Constant pressurizing infusion device for operating room

Abstract

The invention provides a constant-pressurization infusion device for an operating room. The constant-pressurization infusion device comprises an infusion pressurization bag and a circular operation box. After a person sets an infusion pressure value on the control panel, the control panel is used for controlling the air compressor to be started through the controller, and when the pressure sensor detects that the pressure in the infusion pressurization bag exceeds the set pressure value, the controller controls the air compressor to be closed, and meanwhile the pressure sensor and a second electromagnetic pressure release valve are started; when the pressure sensor detects that the pressure in the infusion pressurization bag is lower than a set pressure value, the controller controls the air compressor to be started, and meanwhile, the pressure sensor and the second electromagnetic pressure release valve are closed, so that automatic pressure supplementing is achieved; therefore, the transfusion pressurizing bag can conveniently and uniformly extrude a blood bag and a transfusion bag in the gauze bag at constant pressure, the purpose of rapid blood transfusion and transfusion is achieved, continuous manual operation is not needed, operation is accurate, and repeated use can be achieved.

Description

technical field [0001] The invention relates to the technical field of medical infusion pressure bags, in particular to a constant pressure infusion device used in an operating room. Background technique [0002] The infusion pressure bag is mainly used for rapid pressure input during blood transfusion to help the bagged liquids such as blood, plasma, cardiac arrest fluid enter the human body as soon as possible, and can also continuously pressurize the heparin-containing liquid to flush the built-in arterial pressure measuring tube. , easy to use, safe and reliable, is a must for battlefield, field and clinical emergency treatment; [0003] Usually, the plasma bag or infusion bag is put into the interlayer of the infusion pressure bag, the hanging rope of the plasma bag or infusion bag is stringed into the sling belt of the infusion pressure bag, and then it is hung on the infusion fixed frame, and then squeezed by hand. The ball is inflated, and the gas flows into the air...

AI Technical Summary

Problems solved by technology

[0003] Usually put the plasma bag or infusion bag into the interlayer of the infusion pressurized bag, string the hanging rope of the plasma bag or infusion bag into the ring belt of the infusion pressurized bag, then hang it on the infusion fixed shelf, and pinch it by hand The ball is inflated, and the gas flows into the air bag of the infusion pressurized bag through the valve and the trachea; the speed of the infusion can be adjusted by the high and low pressure of the infusion pressurized bag; The valve is opened to release the air, and the gas in the air storage bag is discharged; if the infusion is continued, the above action will be repeated, which will increase the consumption of artificial physical strength, resulting in the inability to accurately adjust the pressure of the pressurized bag, and further unable to perform infusion at a constant pressure. When working with a controlled compressor, it cannot be assisted in cooling, which increases the risk of use and increases the cost of construction. Therefore, a constant pressurization infusion device for operating rooms is proposed.
