Vacuum definition: A space in which the pressure is far below atmospheric pressure so that the remaining gases do not affect processes being carried on in the space.
Vacuum Curettage definition: Aspiration of the contents of the uterus with a vacuum curette.
Vacuum Extraction, Obstetrical definition: Removal of the fetus from the uterus or vagina at or near the end of pregnancy with a metal traction cup that is attached to the fetus' head. Negative pressure is applied and traction is made on a chain passed through the suction tube. (From Stedman, 26th ed & Dorland, 28th ed)
Aspirators definition: Devices that are used to evacuate gas, fluid, tissue, or other foreign materials from a body cavity by means of suction. They generally consist of a motorized suction pump (some hospitals have a central vacuum system), rubber tubing, a plastic/glass specimen container, a pressure gauge, a vacuum control adjustment knob, and sometimes, a microbial filter. The pump creates a vacuum in the suction tubing, which is inserted into the cavity for the removal of gases, fluids, or other particles, which are removed and routed to the specimen container. Aspirators may also consist only of a simple rubber bulb and pipette that is inserted into the cavity and manually squeezed to remove the fluid, gas, or other material. Typically, these devices are used by surgeons, assisting surgeons, or nurses during surgery, but they may also be used at the bedside, in the home, in long-term nursing home facilities, and during emergency medical response.
BOTTLE, COLLECTION, VACUUM definition: A vacuum-powered body fluid suction apparatus is a device used to aspirate, remove, or sample body fluids. The device is powered by an external source of vacuum. This generic type of device includes vacuum regulators, vacuum collection bottles, suction catheters and tips, connecting flexible aspirating tubes, rigid suction tips, specimen traps, noninvasive tubing, and suction regulators (with gauge).
Mattresses, Vacuum definition: Mattresses that mold to the contours of the patient's body when a relative vacuum is obtained by pumping the air out of them. These mattresses are typically made of a strong fabric (e.g., vinyl/polyester laminate) filled with plastic (e.g., polystyrene) beads; the air is evacuated from the mattress using a manual pump. Vacuum mattresses permit the immobilization of patients during transportation, also providing thermal insulation; they are used to transport patients either by using their own handles or by placing them on a portable or ambulance stretcher.
REGULATOR, VACUUM definition: A vacuum-powered body fluid suction apparatus is a device used to aspirate, remove, or sample body fluids. The device is powered by an external source of vacuum. This generic type of device includes vacuum regulators, vacuum collection bottles, suction catheters and tips, connecting flexible aspirating tubes, rigid suction tips, specimen traps, noninvasive tubing, and suction regulators (with gauge).
Splints, Vacuum definition: Soft splints that form around an injured body part by applying suction to a valve in the splint to remove the air inside. This type of splint becomes rigid when all air is removed and the valve is sealed, thus conforming to the injured body part and immobilizing it.
Brushes, Dental, Prophylaxis, Vacuum-Supplemented definition: Dental brushes designed for connection to a suction unit to facilitate simultaneous manual cleaning (i.e., prophylaxis) of teeth and removal of fluid and particles from the mouth. These brushes typically consist of a hollow-handle evacuating brush that may be connected via a flexible tube to a healthcare facility vacuum outlet or to a dedicated portable suction unit. Vacuum-supplemented manual brushes permit the removal of debris, plaque, bacteria, and fluid from the mouth during dental procedures; they are also used in people who are unable to swallow or have difficulty swallowing and expectorating and/or in emergency situations.
EXTRACTOR, VACUUM, FETAL definition: A fetal vacuum extractor is a device used to facilitate delivery. The device enables traction to be applied to the fetal head (in the birth canal) by means of a suction cup attached to the scalp and is powered by an external vacuum source. This generic type of device may include the cup, hosing, vacuum source, and vacuum control.
Vacuum Cleaners definition: Electrical devices that clean by trapping small particles using a suction vacuum pump and appropriate filters and collection bags.
Vacuum Cleaners, Micrometric Filtration definition: Vacuum cleaners employing a high-efficiency particulate-air (HEPA) filter and appropriate air-tight seals and collection bags to trap micrometric particles which cause upper-respiratory disorders and adversely affect allergy sufferers.
CONTROLLER, ABORTION UNIT, VACUUM definition: A vacuum abortion system is a device designed to aspirate transcervically the products of conception or menstruation from the uterus by using a cannula connected to a suction source. This device is used for pregnancy termination or menstrual regulation. This type of device may include aspiration cannula, vacuum source, and vacuum controller.
Electric Permittivity of Vacuum definition: A constant of proportionality that exists between electric displacement and electric field intensity in a vacuum. This constant is equal to approximately 8.854187817x10E-12 farad per meter (F/m).
permittivity of vacuum definition: 8.854187817 x 10-12 F/m
permittivity of vacuum definition: 8.854187817 x 10-12 F/m
permeability of vacuum definition: 1 4.[pi].10*-7.N/A2
permeability of vacuum definition: 1 4.[pi].10*-7.N/A2
Vacuum Cleaners, Laboratory Fluid definition: Vacuum cleaners designed to collect fluids from laboratory equipment. These cleaners typically include a vacuum pump and a refrigerated vapor trap chamber to recover the fluids. Laboratory fluid vacuum cleaners are intended for fluid (e.g., solvent) recovery from equipment that uses vacuum technologies (e.g., gel dryers).
Laboratory Concentrators, Specimen, Centrifugal/Vacuum definition: Specimen concentrators designed to increase the relative content of substances in a sample (i.e., specimen) using a combination of centrifugal force, vacuum, and heat to speed evaporation. Vacuum concentrators usually consist of a tabletop device that includes a centrifugation mechanism capable of using several interchangeable rotors, a vacuum pump, speed and time controls, a display, and vacuum relief valves. Vacuum specimen concentrators are used mainly in clinical laboratories to concentrate biochemistry and/or microbiology samples when maximum throughput is required.
