A medical aspirator is a suction machine used to remove mucus, blood, and other bodily fluids from a patient. They can be used during surgical procedures but an operating theater is generally equipped with a central system of vacuum tubes. [1]
Negative pressure wound therapy device. Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction pump, tubing, and a dressing to remove excess wound exudate and to promote healing in acute or chronic wounds and second- and third-degree burns.
A vacuum mattress, or vacmat, is a medical device used for the immobilisation of patients, especially in case of a vertebra, pelvis or limb trauma (especially for femur trauma). [1] It is also used for manual transportation of patients for short distances (it replaces the stretcher ).
In many hospitals and other health facilities, suction is typically provided by suction regulators, connected to a central medical vacuum supply by way of a pipeline system. The plastic, rigid Yankauer suction tip is one type of tip that may be attached to a suction device. Another is the plastic, nonrigid French or whistle tip catheter.
The intermittent vacuum therapy (IVT) is a treatment conducted in case of venous and arterial issues as well as in rehabilitation (after sports injuries [1] and vascular complaints). With the aid of normal and low pressure , it should enable to control venous reflux, enhance lymphatic flow [ 2 ] and improve blood flow in periphery and muscles.
This article needs to be updated.The reason given is: the section related to E.U. needs further updates (esp. in sections 3.2 and 4.2.2) as the directives 93/42/EEC on medical devices and 90/385/EEC on active implantable medical devices have been fully repealed on 26 May 2021 by Regulation (EU) no. 2017/745 (MDR); furthermore, Brexit triggers updates in these sections (U.K. developed their own ...
The pump of the phacoemulsification system can be a peristaltic type or a vacuum transfer type. In peristaltic pumps aspiration flow rate and vacuum are independent. Vacuum is the suction force which holds cataract nuclear fragments against the phaco tip so that they can be emulsified, and draws the emulsion into the tip. [3]
On the other hand, the vacuum extractor uses a small metal or silicon cap that exerts negative pressure on the fetal scalp to facilitate pulling of the infant. [20] Since vacuum extraction can cause less injuries to the mother than forceps-assisted delivery, it is the preferred technique in some countries.
