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.

Suture anchor system is a **medical device** used to secure soft tissue (such as tendon, ligament, or labrum) to bone during orthopedic and sports medicine procedures. In practical terms, it combines an **implantable anchor** (placed in bone) with **sutures or suture tape** and the **insertion instruments** needed to deploy and tension the construct. The goal is to create reliable fixation while enabling efficient surgical workflow, often in minimally invasive (arthroscopic) settings.

A Meniscal repair device is a surgical **medical device** used during knee arthroscopy to help **approximate and secure torn meniscal tissue**, most commonly by placing sutures and/or small implantable anchors across a tear. In many hospitals and ambulatory surgery centers, meniscal repair sits at the intersection of clinical outcomes, operating room (OR) efficiency, infection prevention, and supply chain discipline—because these systems often involve **sterile, single-use implants**, specialized delivery instruments, and strict traceability requirements.

An Arthroscopy pump is a fluid management medical device used during arthroscopic (minimally invasive) joint procedures to deliver irrigation fluid at a controlled pressure and/or flow. By maintaining joint distension and clearing blood and debris from the camera’s view, it supports visualization, procedural efficiency, and overall operating room (OR) workflow.

Bone density ultrasound heel is a **quantitative ultrasound (QUS)** medical device designed to assess bone-related parameters at the **calcaneus (heel bone)**. It is used in many clinical and community settings to support **bone health risk assessment**—often where access to dual-energy X-ray absorptiometry (**DXA**, also written DEXA) is limited, or where a fast, portable, non-ionizing test is operationally helpful.

A **Skeletal traction pin set** is a small but high-impact piece of orthopedic **medical equipment** used to apply traction directly to bone using a percutaneous (through-the-skin) pin or wire. Unlike skin traction (which pulls through bandages and soft tissue), skeletal traction transfers force to the skeleton, which can help maintain limb length, alignment, and comfort while a patient awaits definitive treatment or ongoing management.

Orthopedic traction frame is a mechanical medical device used to apply a controlled pulling force (traction) to an injured limb or body segment to help maintain alignment, reduce muscle spasm, and support stabilization during assessment, transport, inpatient care, or selected surgical workflows. In many hospitals it is part of essential orthopedic hospital equipment because it can be deployed quickly, does not require complex electronics, and can be adapted to different patient sizes and clinical settings.

Cast saw is a powered medical device used to cut and remove rigid orthopedic casts and some types of splints. It is common hospital equipment in emergency departments (EDs), orthopedic clinics, plaster rooms, and pediatric services—anywhere immobilization is applied and later needs safe, efficient removal.

Radiofrequency ablation catheter is a sterile, flexible clinical device used to deliver radiofrequency (RF) electrical energy to targeted tissue inside the body. When used with an RF generator and appropriate monitoring, it creates controlled thermal injury (an “ablation lesion”) intended to modify tissue function—most commonly in cardiac electrophysiology (EP) procedures, but also in selected vascular and endoluminal applications depending on the model and specialty.
