An **Autotransfusion cell saver system** is a hospital medical device designed to collect a patient’s shed blood during surgery or trauma care, process it (typically by filtering and washing), and then return concentrated red blood cells (RBCs) back to the same patient. In many operating rooms (ORs), it sits alongside anesthesia and surgical workflows as part of **patient blood management**—a coordinated approach to reduce avoidable blood loss and optimize transfusion decisions.

Extracorporeal membrane oxygenation (ECMO) is a form of **extracorporeal life support (ECLS)** in which blood is circulated outside the body through a **membrane oxygenator** that adds oxygen and removes carbon dioxide, then returned to the patient. An **Extracorporeal membrane oxygenation ECMO system** is the integrated medical device (console, pump, oxygenator interface, sensors, alarms, and accessories) used to deliver that support safely in critical care environments.

A Retinoscope is a handheld optical medical device used to perform **retinoscopy**—an objective method of estimating refractive error (for example, myopia, hyperopia, and astigmatism) by observing how light reflects from the patient’s retina. Unlike tests that depend heavily on patient responses, retinoscopy can be performed even when communication is limited, which is why this clinical device remains widely used in eye clinics, pediatric services, and training programs.

Prism bar set is a small, non-powered ophthalmic medical device used to quantify ocular misalignment (for example, strabismus) by neutralizing eye movements during standard bedside and clinic examinations. It matters because accurate measurement of deviation helps clinicians document baseline findings, track changes over time, and communicate consistently across teams—especially in pediatrics, neuro-ophthalmology, emergency referrals, and pre-/post-operative assessments.

Occluder paddle is a simple, handheld clinical device used to temporarily block vision in one eye during eye examinations. It is most commonly seen in ophthalmology, optometry, orthoptics (assessment of eye alignment and binocular vision), pediatrics, and vision screening programs. Despite its low-tech appearance, it plays an outsized role in how clinicians measure monocular (one-eye) visual function and assess binocular alignment in a consistent, reproducible way.

Stereoacuity test kit is a **vision-testing medical device** used to assess **stereopsis** (binocular depth perception) by presenting slightly different images to each eye and measuring how well the brain fuses them into a 3D percept. In hospitals and clinics, it is commonly used alongside visual acuity testing, ocular alignment assessment, and broader neuro-ophthalmic evaluation.

Color vision test plates are a widely used, low-technology clinical device designed to screen for color vision deficiencies (also called color vision defects). Although the tool looks simple—typically a booklet or set of printed plates with colored dot patterns—it plays an outsized role in ophthalmology clinics, occupational health programs, primary care screening, and hospital pre-employment assessments.

Portable vision screener is a handheld or easily transportable clinical device used to *screen* for vision problems and vision risk factors—most commonly refractive error (e.g., myopia/near-sightedness, hyperopia/far-sightedness, astigmatism) and ocular misalignment (strabismus). It is designed to help clinicians identify people who may need a more complete eye examination by optometry or ophthalmology, especially in settings where time, patient cooperation, or access to specialty care is limited.

Handheld slit lamp is a portable ophthalmic examination medical device that combines a bright, narrow “slit” beam of light with magnification to help clinicians inspect the front structures of the eye (the “anterior segment”). It matters because many eye problems present outside dedicated eye clinics—such as in the emergency department (ED), intensive care unit (ICU), perioperative areas, pediatrics, and outreach settings where a tabletop slit lamp is not available or a patient cannot sit upright.

A Non mydriatic fundus camera is a retinal imaging medical device designed to capture photographs of the back of the eye (the fundus) through a pupil that has not been pharmacologically dilated. In many care pathways—especially diabetes and hypertension follow-up—fundus imaging supports earlier detection of retinal disease, better documentation, and safer referral decisions.

Corneal pachymeter handheld is a portable medical device used to measure corneal thickness (also called pachymetry). In everyday ophthalmology practice, corneal thickness is more than a number: it can influence how clinicians interpret intraocular pressure (IOP), assess corneal health, and plan or follow procedures where corneal integrity matters.

Auto lensometer is a clinical device used to measure the optical power of spectacle lenses (eyeglasses). In practical terms, it helps a clinic or optical service confirm what a pair of glasses is doing—how strong the lenses are, whether there is astigmatism correction (cylinder and axis), whether prism is present, and (for bifocals/progressives) what the near “add” power is. It measures the lens, not the patient’s eye.

A Kinesiology tape dispenser is a purpose-built tool used to hold, dispense, measure, and cut rolls of kinesiology tape in a controlled and repeatable way. Although it may look simple compared with high-acuity hospital equipment, it can meaningfully affect day-to-day workflow in rehabilitation, sports medicine, orthopedic clinics, and any setting where taping is performed frequently.

A **Cold compression unit** is a clinical device used to deliver **controlled cold therapy (cryotherapy)**—often combined with **intermittent or continuous compression**—through a pad, cuff, or wrap applied to a body region. You will most often see it around orthopedic pathways (sports injuries, postoperative recovery, joint and soft-tissue procedures), but it also appears in rehabilitation and outpatient settings where swelling and discomfort are being managed under supervision.

Compression therapy device sports refers to medical devices and medical equipment that apply controlled external pressure to a limb (most often the legs, sometimes the arms) in contexts that include sports medicine, rehabilitation, and hospital-based care. Depending on design, these devices provide **static compression** (e.g., stockings, sleeves, wraps) or **intermittent pneumatic compression (IPC)** (e.g., powered pumps with inflatable cuffs/boots that cycle pressure).

A Walking boot CAM boot is a removable orthopedic immobilization device designed to protect the foot and ankle while allowing some level of functional mobility. “CAM” commonly refers to **Controlled Ankle Motion**: the boot’s structure limits unwanted movement (especially at the ankle) while its sole and shell help distribute load during standing and walking. In many health systems, it sits in the overlap between **hospital equipment** (issued in emergency departments and clinics), **durable medical equipment (DME)** (managed through outpatient pathways), and an **orthotic clinical device** (fitted and adjusted by trained staff).

Orthopedic brace TLSO is a **thoracolumbosacral orthosis**—a medical device worn on the torso to support and limit movement of the **thoracic (upper/mid back), lumbar (lower back), and sacral (pelvic) spine**. In hospitals and clinics, TLSO bracing sits at the intersection of trauma care, spine surgery, rehabilitation, nursing workflows, and orthotics/prosthetics services. It is frequently used in time-sensitive settings where teams need a practical way to stabilize the trunk, facilitate safer mobility, and standardize care plans while a patient’s definitive treatment (operative or non-operative) is underway.

Internal bone stimulator is an implantable medical device designed to deliver a controlled bone-growth stimulation signal at or near a fracture, nonunion site, or spinal fusion bed. In practical terms, it is one more tool a surgical team may use when bone healing is expected to be challenging or when a prior attempt at healing has not progressed as planned.

External bone stimulator is a noninvasive medical device designed to deliver a controlled physical signal (such as an electromagnetic field, electrical field, or ultrasound energy) through the skin to support bone healing. In many care pathways it is used as an adjunct to standard fracture or fusion management, particularly when healing is slow or the risk of delayed healing is higher.

A **Powered reamer system** is a motor-driven surgical instrument set used to **enlarge, shape, or prepare bone canals and cavities**. You will most often see this medical device in orthopedic trauma and reconstructive surgery, where controlled bone preparation supports accurate implant placement, stable fixation, and efficient operating room (OR) workflow.

An **Orthopedic navigation system** is a computer-assisted surgical navigation **medical device** used in the operating room (OR) to help orthopedic teams **track anatomy and surgical instruments in real time**. By translating patient anatomy and instrument movement into on-screen guidance, it supports tasks such as bone resection alignment, implant positioning, and trajectory planning during procedures like joint replacement and spine instrumentation.

An **ACL fixation device** is a surgical implant and/or associated instrumentation used to **secure an anterior cruciate ligament (ACL) graft** during **ACL reconstruction**. In plain language, it helps the surgeon **anchor a tendon graft to bone** until the body incorporates the graft and restores functional knee stability. These devices are common in orthopedic operating rooms (ORs), ambulatory surgery centers, and sports medicine programs.
