An apparatus, tool, or machine made for a specific function.
A trapezoidal pillow, wedge, or splint placed between the arm and torso to prevent adduction. It is commonly used postoperatively for patients having total joint replacement or open reduction or internal fixation of the hip or shoulder. See: illustration
adaptive deviceAssistive technology.
adaptive seating device Abbreviation: ASD
A device that provides a proper sitting position for those with limited motor control. Such devices include seating inserts, wheelchairs, and postural support systems designed to prevent deformities and enhance function. Synonym: seating system

A device that helps people with limited or no speech to communicate. Examples include communication boards, pictographs, or ideographs (symbols representing ideas, not sounds).
BAG MASK DEVICE
bag mask device
A manually operated resuscitator used to ventilate a nonbreathing patient or assist the ventilation of a patient who is not breathing at an effective rate or tidal volume. The device consists of a bag, an oxygen reservoir system, a one-way flow valve, and a clear face mask. It is designed to be attached to an oxygen source by tubing to deliver concentrations approaching 100%. See: illustration
A device using friction to brake or slow the movement of a rope, or to protect a patient, basket, climber, or other rescuer.
biventricular assist device Abbreviation: BiVAD
A device that helps both ventricles of the heart contract more effectively. It is used to treat heart failure by propelling blood out of the chambers of the heart.
cardiac rhythm management device Abbreviation: CRMD
An umbrella term for pacemakers and implantable cardioverter/defibrillators.
cervical immobilization device Abbreviation: CID
A stiff neck brace or collar to prevent movement of the cervical spine in order to maintain spinal alignment and prevent injury or paralysis.
charge-coupled device Abbreviation: CCD
A device used in video and digital imaging (such as in CT scanning) that creates electronic images from light.
clitoral vacuum device
A mechanical device used to engorge and stimulate the clitoris. It is used as a U.S. FDA–approved treatment for female sexual dysfunction.
electronic infusion device Abbreviation: EID
A device for monitoring intravenous infusions. The device may have an alarm in case the flow is restricted because of an occlusion of the line. In that case, the alarm will sound when a preset pressure limit is sensed. The device can also signal that an infusion is close to completion. The pressure is regulated by the height at which the container is positioned above the level of the heart when the patient is lying flat. A height of 36 in (91 cm) provides a pressure of 1.3 lb/sq in (70 mm Hg). Most EIDs are equipped to stop the flow of the infused liquid if accidental free flow occurs. See: infusion pump
esophageal intubation detector device
A syringe attached to the endotracheal tube immediately after an intubation attempt.
If aspiration is difficult or stomach contents are withdrawn, or both, the endotracheal (ET) tube may have been placed in the esophagus and needs to be removed and reinserted. If aspiration is easy and free of stomach contents, it is probable that the ET tube is located in the trachea; the rescuer should then confirm tube placement by other techniques, e.g., a combination of auscultation, x-ray, and pulse oximetry.
femoral compression device
A device used to apply pressure to the large artery or vein in the thigh after it has been cannulated in order to reduce bleeding from the punctured vessel. Femoral compression devices are used, e.g., after angiography.
flow-restricted oxygen-powered ventilation device Abbreviation: FROPVD
Flutter device See: Flutter device
head immobilization device
A device that attaches to a long back board and holds the patient's head in neutral alignment. See: long back board
humanitarian use deviceHumanitarian device exemption.
improvised explosive device Abbreviation: IED
Military jargon for a homemade bomb or land mine used in unconventional warfare.
In assistive technology, the device that activates an electronic device. This can be a manual switch, a remote control, or a joystick. See: switch
inspiratory impedance threshold deviceInspiratory impedance threshold valve.
intrauterine contraceptive device Abbreviation: IUCD, IUD
See: intrauterine contraceptive device.
Kendrick extrication device See: Kendrick extrication device
left ventricular assist device Abbreviation: LVAD
A pump surgically implanted in patients with severe heart failure to move blood from the left ventricle to the ascending aorta. The LVAD usually augments the heart's function until it heals (following a severe myocardial infarction) or until a heart transplant becomes available, e.g., for patients with heart failure with a markedly diminished ejection fraction. The LVAD also may be used permanently for a patient who does not meet criteria for transplantation.
A speech amplifier that aids the hearing-impaired in direct person-to-person communication or telephone conversation. Such devices differ from conventional hearing aids in that they reduce interference from background noises.
Any health care product that is intended for the diagnosis, prevention, or treatment of disease and does not primarily work by effecting a chemical change in the body
Any assistive technology that aids the movement of people with physical impairments. Examples include lift chairs, scooters, or wheelchairs.
A device that has no exposed sharp surface, used to inject drugs and fluids. It is designed to decrease the risk of needle-stick injuries by health care professionals.
oxygen-conserving device Abbreviation: OCR
Any device that reduces the loss of administered oxygen into the environment, e.g., one that releases oxygen to a patient only when the patient inhales.
oxygen-powered ventilation device
A multifunction ventilation devicehat uses high-flow oxygen. This device can often be triggered by negative pressure caused by an inhaling patient; it can also be operated by a button while the operator watches the patient's chest rise.
CAUTION!During resuscitation, it is necessary to use the positive-pressure aspect of this device and manually trigger or compress the button because the patient cannot open the valve by inhaling. These devices should be fitted with an overinflation high-pressure alarm to avoid gastric distention and/or barotrauma.
personal flotation device Abbreviation: PFD
A life vest to prevent drowning and near drowning. People engaged in water sports, such as boating or water skiing, or rescuers working on or near the water should wear PFDs at all times. The U.S. Coast Guard sets standards and establishes specifications for the manufacture and use of PFDs. Personal flotation devices may be used to provide added buoyancy for the patient during aquatic therapy.
personal assistive mobility devicePersonal mobility device.
personal mobility device
Any assistive device that facilitates individual human transportation. Examples include powered wheelchairs, scooters, bicycles and unicycles. Although many such devices are used by people with activity or mobility restrictions, mobility aids can be employed generally, e.g., for urban transportation in place of automobiles. Synonym: personal assistive mobility device
A type of input device for sending commands to a computer. Moving the device results in movement of a cursor on the monitor or computer screen. Pointing devices range from the conventional desktop mouse, trackball, and touch-sensitive screens to infrared and ultrasound pointers mounted on the head. See: light pointer; switch
position-indicating device Abbreviation: PID
A device to guide the direction of the x-ray beam during the exposure of dental radiographs. This devices improves and standardizes dental radiographic imaging and reduces the patient's risk of radiation exposure.

There are many types of terminal devices, some of which are designed for use with specific tools and implements. These devices have two primary actions: voluntary opening and voluntary closing. Synonym: hook
An external support applied to vulnerable joints or other body parts to guard against injury. Protective devices include helmets, braces, tape or wrapping, and padding.
A device fitted for use in the vagina to help prevent urinary incontinence. See: pessary
sequential compression device Abbreviation: SCD.
A device to reduce edema or prevent the formation of blod clots in an extremity. A chambered nylon sleeve is progressively inflated from its distal segment to the proximal segment, forcing venous and lymphatic return. Sequential compression devices are inflated with air (pneumatic compression) or, less commonly, chilled water (cryocompression). SCDs are used frequently in the perioperative period. See: intermittent compression
