Finding The Right Surgical And Dental Loupes

Are you trying to select the right pair of surgical and dental loupes for your medical setting? This post will help you better understand these loupes and a few guidelines to follow when selecting the right pair for you.

It’s common for dentists and surgeons to wear loupes throughout a procedure or exam that requires a close view. Surgical and dental loupes will allow the physician or dentist to better see inside a patient’s mouth or body part while having both hands free. The following are four important factors to consider when selecting the right pair of surgical or dental loupes.

1. Working Distance
It is important to determine your correct working distance. Working distance is the space between the eyes and the work area. It is recommended to measure the working distance in the actual setting you will be using the loupes in. It’s important to keep your back straight, head only slightly dipped so you’re viewing the specific area and your feet should be flat on the floor. You can then simply measure (with a measuring tape) from the bridge of your nose to the specific area you will be working on. One of the most common problems in many clinical applications is that the working distance is measured too short, resulting in unnecessary neck strain.

2. Depth of Field
After measuring the working distance, it is important to understand how the depth of field works. The depth of the field is the visible range in focus offered by the loupe. For example, a pair of loupes has a distance of 18 inches and a depth of 5.5 inches. This means that your pair of loupes will stay in focus in a distance of 15.25 inches to 20.75 inches or 2.75 inches on both sides of the working distance range.

3. Field of View

The field of view is simply the working space you are able to visibly see through your loupes. It is important to note that the working distance and field of view go hand in hand. For example, a longer working distance will equate to a larger field of view.

4. Magnification
When looking through a pair of loupes, the size of the image depends on the magnification. A higher magnification amount results in a larger image, but reduces the depth of field and field of view. Typically the level of magnification depends on the preference of the person wearing the loupe. In dentistry, it is common to find 2.5x – 3.5x magnification on dental loupes.

It’s important to identify and understand these factors before selecting your surgical and dental loupes. Be sure to check out our Selecting Dental Loupes video below for additional information. If you have any questions or comments, please feel free to share your thoughts in the comment section.

The Increasing Importance Of Ultrasound In Medicine

While most probably equate an ultrasound guided procedure with a common diagnostic exam done during pregnancy, hospitals, clinics and physicians are using ultrasound in many more ways. Ultrasound has proven to be an effective diagnostic tool for a variety of medical conditions, and it has increased in importance during the past fifty years.

Ultrasound, which is also commonly referred to as a sonogram, works by using sound waves at higher frequencies than the human ear can hear for the purpose of stimulating the tissues in the body. This stimulation gives the technician the ability to view and monitor images such as the flow of blood and the movement of the body’s internal organs. These images are presented in real-time on a screen. In recent years, the images ultrasound has been able to present have increased in quality. Only twenty years ago, the images were one-dimensional, and difficult to decipher for the untrained eye. However, recent developments in technology have resulted in better-quality pictures, including 3-D images, giving physicians even better diagnostic ability.

Because ultrasound uses non-ionizing radiation, physicians consider it to be minimally-invasive and safe in most cases. In addition to being used during pregnancy to ensure a healthy baby and check for any other abnormalities, ultrasound has proven to be a valuable diagnostic tool in procedures like breast biopsies, liver biopsies and a host of others. It’s also commonly used to view potentially cancerous tumors in the body. In the past, physicians would use surgically-invasive procedures to perform such biopsies. In order to avoid the risk that accompanies any type of surgery, physicians began utilizing ultrasound and found it to be very useful.

Ultrasound is also less expensive than performing a lengthy surgical procedure. Its portability is an added feature; one that has made it a standard piece of equipment utilized by emergency personnel all over the country. EMT response teams are able to make quick use of ultrasound when administering first aid to provide additional information to the hospital before the patient even arrives.

Ultrasound gel is a vital part of the ultrasound guided procedure. It is the conductive medium which is placed on the patient’s skin or on the transducer right before the exam. Not only does ultrasound gel help guide the transducer during the procedure, it also improves the quality of the images the technician is able to see on the screen. Because these images play such a crucial role in helping physicians to make accurate diagnoses, ultrasound gel is necessary wherever ultrasound is performed.

Ultrasound gels such as our Aquasonic Ultrasound Gel provide technicians and physicians with the best possible results during any ultrasound guided procedure. Aquasonic Ultrasound Gel is non-staining, hypoallergenic, and completely safe for all types of transducers. This particular gel is high-quality, with an acoustically-correct formula that works well with the large range of frequencies used in many different types of ultrasounds.

One of the most common complaints from patients who have an ultrasound is the coldness of the gel. For this reason, many physicians prefer the use of gel warmers such as our Thermasonic Gel Warmers. These warmer come in two different sizes, allowing technicians to keep more than one bottle of gel warm at a time.

The importance of ultrasound is increasing. With continuous advances in technology, there’s no doubt there will be even more uses for it in the future. Having the proper equipment on hand is vital to ensure that every patient receives the most accurate diagnosis possible. If you have any questions or comments, please share your thoughts below!

Using Ultrasound Lotion In Therapeutic Ultrasound Treatments

Therapeutic ultrasound treatments generally refer to any type of therapeutic treatment that uses ultrasounds. A therapeutic ultrasound is a technique that consists of stimulating tissue underneath the skin’s surface through sound waves. These ultrasound treatments can include pain management, physical therapy and a variety of other treatments used in rehabilitation centers.

Similar to how ultrasound gel in diagnostic imaging is an essential product, ultrasound lotion for therapeutic ultrasound treatments is just as essential. Polysonic Ultrasound Lotion is available in 1 gallon jugs, dispensers and pump sizes to accommodate your treatment setting. This multi-purpose ultrasound lotion has a rich, moisturizing formula that is recommended for medical ultrasound procedures where lotion is preferred. Compared to ultrasound gel, the ultrasound lotion is often preferred by medical staff and patients in therapeutic ultrasound treatments. This ultrasound lotion is easily absorbed by the skin during massage, manual application and other physical therapy modalities during therapeutic treatments.

At the beginning of a therapeutic ultrasound treatment, ultrasound lotion is applied to the area of the patient’s body that is being treated. The probe from the ultrasound machine will then circulate the ultrasound lotion against the affected area of the patient. Depending on the type of treatment, generally the ultrasound stimulates a patient’s tissue beneath the surface of skin using high frequency sound waves. Therapeutic ultrasounds not only have the possibility to create heating effects, but its also shown to increase tissue relaxation, increase in blood flow to reduce swelling and inflammation and breakdown of scar tissue.

Therapeutic ultrasound treatments can treat a large variety of pain management therapies including muscle strain, muscle tension, chronic pain, and injuries toward tendon, muscle and ligaments. It is important to use the appropriate ultrasound lotion to assist in these types of treatments. If you have any questions or comments regarding this post, please leave your thoughts below!

Diode Laser Glasses Prevent Retinal Damage

Laser medical safety for doctors, nurses and lab technicians involves following safe procedures and wearing protective gear to shield themselves against harmful radiation. When working around diode laser systems, it is important that laser safety precautions are followed.

To prevent accidental eye exposure during a laser procedure or treatment, Universal Medical offers the latest safety eyewear. The diode laser eyewear selection includes adjustable, spectacle style design, soft padded goggles, wrap around, frames with side protection and fit over glasses. With this variety of diode laser glasses, you’ll have no problem finding the right frames for your medical personnel. The adjustable (model 66) diode laser glasses and the wrap around (model 808) diode laser glasses are available in multiple colors to help you differentiate glasses between medical workers.

Certified laser safety officers help to prevent damage from direct laser radiation, reflected beams and accidents. Laser safety requirements in the medical setting include diode laser glasses to meet ANSI and OSHA standards.

Lightweight polycarbonate lenses in laser glasses protect eyes from the appropriate laser and they’re comfortable for medical staff to wear throughout extended procedures and treatments. Many of the diode laser eyewear options include side shields, soft padding, adjustable nose pieces, unisex frames and durable resilience. Laser diode glasses focus on safety as their primary purpose and polycarbonate lenses help filter certain wavelengths of light from diode lasers.

Optical density describes the amount of light that laser glasses allow to pass through the filters. An optical density (OD) of 5.0 allows .001 of laser energy to pass through. The larger the number the greater the protection.

Laser diodes use laser energy for various medical purposes, and with the benefits of today’s technology it is increasingly more common in treatment centers. Lasers emit radiation which can cause permanent eye damage without laser eye protection. Diode laser glasses protect medical staff from accidental eye exposure when operating powerful laser systems. The effects of laser radiation to the eye can cumulatively build over time and may not be noticeable right away. Since eye tissue is delicate and considered a sensitive organ the risk of irreversible laser radiation increases.

Diode laser glasses from the wide selection of safety eyewear prove vital for surgical, medical, dental or optical medical facilities that perform diode laser treatments. Doctors and medical staff perform hundreds of laser procedures and cumulative effects or accidents pose high risks. By following recommended safety protocols it will help to eliminate workplace accidents or long-term safety risks for medical personnel.

Why Ultrasound Guided Procedures Are Common In Medical Settings

Ultrasound guided procedures are becoming more common in today’s medical world. Many hospitals, clinics and doctor offices use ultrasound technology for a variety of diagnostic purposes.

An ultrasound is simply a technique to stimulate the tissue underneath the skin’s surface using high frequency sound waves. The ultrasound images are taken in real-time to show the movement of internal organs, as well as blood flow. Technologists will place ultrasound gel on a patient’s skin or probe before the procedure. The ultrasound gel is used as a conductive medium to transmit the sound of waves from the probe to skin, which will then render images on a screen for the technologist to view. Ultrasound exams do not use ionizing radiation, they are considered safe and minimally invasive. The following are a few common ultrasound guided procedures:

  • Ultrasound Guided Breast Biopsy
  • Ultrasound Guided Cervical Spine Injection
  • Ultrasound Guided Liver Biopsy
  • Ultrasound Guided Thyroid Biopsy
  • Ultrasound Guided Thoracentesis

The safe performance of diagnostic procedures is an important part of any medical practice. Both physicians and patients often prefer an ultrasound guided procedure when compared to a surgical, invasive procedure. Ultrasound technology is commonly used in biopsy procedures. When an ultrasound guided breast biopsy is scheduled, it usually means that during a routine mammogram there was an abnormality detected. A breast biopsy is used to extract fluid or cells from the tissue that will be sent to a laboratory for further testing.

Medical facilities such as hospitals, clinics and doctor offices, will continue to use ultrasound technology to treat patients. If you have any questions or comments regarding this topic, please share your thoughts in the comment section below.

How To Safely Use Sterile Ultrasound Gel Packets

Trying to maintain a sterile environment during an ultrasound procedure? It’s very important that all efforts are made to prevent infection and the spread of germs during these procedures and exams. The amount of ultrasound procedures in hospitals and doctor’s offices are increasing. We recommend that physicians and medical personnel use sterile ultrasound gel packets for any medical ultrasound application that requires sterile instruments.

When using non-sterile ultrasound gel in an ultrasound guided procedure, the risk for contamination is increased. The non-sterile ultrasound gel bottle should be squeezed to dispense gel without making contact with the patient’s skin. Bacteria can spread if an ultrasound gel bottle makes contact with a patient’s skin. To prevent this from happening, it is best to supply your medical staff with sterile ultrasound gel packets. These packets are single-use gels that are packaged in sterilized foil pouches.

There are easy steps for medical personnel to follow to ensure the ultrasound gel is sterile throughout the entire process. It is always important to continue using all sterile techniques in the medical setting. At the top of the ultrasound gel package, simply pull both folds away from one another to open. Without touching the inside pouch, drop the pouch onto a sterile surface (typically on a sterile cart or sterile drape depending on your setting). After the pouch is on a sterilized surface, your medical staff will pick up the packet while wearing sterile gloves. The packet has arrows indicating which side to tear in order to dispense the gel onto the patient or probe. Since our sterile ultrasound gel packet is a one time use only, you should discard the packet in the trash after use.

Always keep in mind the importance of maintaining a sterile medical setting when necessary. These ultrasound gel packets will help prevent contamination and spread of infection that may be caused with non-sterile ultrasound gels.

Medical Facilities Looking To Increase Utilization And Organization Of Exam Gloves

Exam gloves are a vital component of every exam room. Doctors, nurses and other medical personnel rely on exam gloves to keep themselves protected against contracting and spreading germs and infections. Because of the need for exam gloves, it’s important to have a way to store them in exam rooms that will help to keep the room organized and yet keep the gloves readily accessible. The best way to do that is by using a glove dispenser that is made from high-quality materials, making it durable and able to last for many years.

Exam gloves, or medical gloves are one of the most common features of any doctor’s office, exam room or hospital room. Using exam gloves is important to decrease the possibility of the spread of infection. Germs are prevalent everywhere, whether a medical professional is working with a patient’s blood, other bodily fluids, or simply when the patient is sick. A glove dispenser keeps exam gloves readily accessible, in a place that makes them easy to use. Glove dispensers help to remind medical professionals to use exam gloves every time they come in contact with a patient. Most hospitals and clinics recommend or even require for exam gloves to be worn with every patient interaction, so glove dispensers make it easier for doctors, nurses and other professionals to observe these requirements.

Few things are as irritating to a physician as an exam room that is cluttered and unorganized. In order to provide patients with the proper medical care, it’s imperative for every tool to be in its proper place. Not only does this make examinations and procedures easier and more efficient, but it also reflects well on the reputation of the facility. A glove dispenser in every room will ensure that gloves are kept in a safe and organized place, which aids in keeping the rest of the room always looking its best. Because of the fact that all exam rooms are different, the glove dispenser can be placed in a room in many ways. It can be placed on a counter top or mounted to the wall. If the room has glass surfaces, the glove dispenser can even be mounted to the glass using suction cups to keep it in place.

Many of our glove dispensers are made of acrylic and some are even clear, allowing the medical staff to clearly see what’s inside. They also come in two, three or four pocket glove dispensers, so each office or hospital can choose the size that’s right for their needs. In addition to our acrylic models, we also offer steel glove dispensers and wire dispensers. There are many choices to suit any type of room design or preferences.

In order to promote the frequent use of exam gloves, as well as keep exam rooms free from clutter, it’s important to use glove dispensers in the rooms. Glove dispensers will help to keep medical personnel healthy by encouraging the frequent use of exam gloves. They will also provide a durable and organized solution for keeping exam rooms looking their best at all times. If you have any questions or comments regarding this post, please feel free to leave a comment below.

Eye Protection Is Imperative Around YAG Lasers

Eye protection is imperative for surgeons, dentists and other medical professionals who are present when lasers are used to treat patients. Permanent eye damage to the cornea or retina can occur if one’s eyes are exposed and subjected to the powerful radiation of a laser. YAG laser glasses and YAG laser goggles provide superior protection for those working in an environment where a YAG laser is in use.

Lasers work by focusing light in a narrow beam. A beam is emitted in short bursts and focuses precisely on the target. A laser’s energy can be absorbed, scattered, transmitted or reflected. Lasers used in medical procedures transmit most of their energy to the intended target, however it is possible that some of that power can be reflected toward the eyes. In a medical setting, it is important to wear protective safety glasses due to this possibility. YAG laser glasses and YAG laser goggles are fully compliant with ANSI Z136.3 standards when working with Class 3B and Class 4 lasers in a medical setting.

Protective glasses must be matched in terms of wavelength frequency with the type of laser being used. Medical professionals, who work with Class 3B and Class 4 lasers, are protected by using 1064 nm (nanometer) laser glasses and goggles. Instead of using heavier and more expensive glass, the lenses of YAG laser glasses are made of a lighter and less expensive polycarbonate material. These lenses permit 58.7% of the available light to pass through and filter out the harmful wavelength light produced by the laser.

YAG laser glasses and goggles are available in a number of different styles to suit individual preferences. All styles provide the same protection and their lightweight lenses make them very comfortable when using them for long procedures. YAG laser goggles and YAG fit over frames can be worn over regular eyeglasses to accommodate those with existing eyewear.

Whenever YAG lasers are in operation it is absolutely necessary that safety glasses (glasses that meet American National Standards Institute requirements) are worn. Protective eyewear must match the wavelength frequency of the laser being used to properly filter out the harmful radiation. Lasers used in medical procedures are inherently dangerous, particularly to the unprotected eye. Very few incidents of eye injuries are reported when properly fitted YAG laser glasses or YAG laser goggles are worn. Protect your eyesight and never take chances when working around lasers.

A Combination Of Safety And Style In Holmium Laser Safety Glasses

Safety laser glasses are mandated for all medical personnel employed at facilities that work with high power Class 3B and Class 4 lasers in the healthcare industry, including dental, cosmetic, medical and surgical facilities. Holmium laser safety glasses, clear Yag laser glasses and goggles are designed to protect personnel from the dangerous laser radiation associated with Yag, CO2 and Holmium lasers.

Lasers can cause damage due to its thermal effects. Even mildly powered lasers can be harmful. The thermal effects enter the pupil and cause damage to the photoreceptor cells in the retina. Often, the damage is irreversible. Since lasers have a low divergence beam, its wavelength focuses on very small areas. The blink of an eye is not enough to prevent permanent ocular damage. In addition, the wavelength is invisible to the human eye. When selecting Holmium laser safety glasses or clear Yag laser glasses, it’s a matter of selecting a pair with both sufficient eye protection and good visibility. Since laser light has a specific wavelength dependent on the laser medium, protective filters that match the wavelength are needed.

At Universal Medical, we outline frequency ranges and optical density so that you can choose the best laser safety glasses for your medical staff, physicians and patients. The optical density measures the level of absorption of a specific wavelength. The higher the optical density, the more laser radiation is blocked out. Our Holmium laser safety glasses and clear Yag laser glasses have filters that are fabricated of clear glass and allow for superb visible light transmission. As a result, the visibility of objects and patients is clear and crisp. With a clear viewing field, medical procedures can easily be done with accuracy. Our laser safety glasses also last longer because of its durable composition.

You’ll also find that our Holmium laser glasses and clear Yag laser glasses are available in a wide variety of stylish frames that are very comfortable. Choose from aviator, wraparound and fit-over frames. For the best in laser safety glasses, make sure to check out the holmium clear laser glasses section on our website.
