How the negative pressure suction device works in the hospital operating room

Medical negative pressure suction device, also known as suction device (negative pressure suction system), is a necessary rescue equipment commonly used in clinical departments. Operating rooms are an important place for the treatment of various surgical diseases, and they are used more frequently.

The operating room negative pressure suction device is used to attract bleeding, exudates, pus, contents of cavity organs, and irrigation fluid during surgery, so that the field of vision during surgery is clear, reducing the chance of contamination, and can also be used for general anesthesia patients to aspirate sputum.
The operating room negative pressure suction device uses the vacuum working principle to generate negative pressure in the cavity, so as to guide the liquid in the cavity out and achieve the purpose of sewage purification. The central negative pressure suction device widely used in the hospital operating room is to form a negative pressure through the central pumping station, which is connected to each operating room by a closed suction pipe, and maintains a constant negative pressure for 24 hours for drainage, sputum discharge, discharge of blood and secretions.

The suction force of the negative pressure suction system and the stability of the work are directly related to the process of surgery. At present, the oil-run rotary vane vacuum unit and the oil-free rotary vacuum unit designed by Yazhi reed are widely used in hospital operating rooms.

The oil rotary vane vacuum negative pressure suction system is mainly composed of the oil rotary vane vacuum pump, vacuum tank, negative pressure automatic control cabinet, dirt collection tank, filter, sound and light alarm, valve instrument, connecting pipe and suction terminal.
Working principle and features:
1. The negative pressure source is the vacuum unit of the oil rotary vane of the central suction station, which makes the suction system pipeline reach the required negative pressure value through the suction of the suction of the suction vane vacuum pump, and provides negative pressure, suction, suction, sputum, pus and other internal dirt for the operating room, rescue room and terminals of each ward.
2, the oil rotary vane vacuum negative pressure suction station is designed as a dual-way system, two vacuum pumps one to work, one standby, when the vacuum flow is insufficient, two can also work at the same time.
3. Self-start and remote sound and light alarm function.
4. Energy saving and environmental protection, no need for water.

Yazlad provides a comprehensive solution for all kinds of medical institutions with central negative pressure suction device, which is suitable for various occasions such as operating rooms and wards. Welcome to inquire!
