Stable pressurizing equipment for medical emergency blood transfusion and infusion bag

Abstract

The invention discloses stable pressurizing equipment for a medical emergency blood transfusion or infusion bag. The problems that a traditional pressurizing mode is manual, the manual operation pressure fluctuation is large, which is not conducive to safe and rapid infusion, blood transfusion and infusion in an operating room and ICU adopt gravity or manual pressurizing bags, use scenes are limited, which is time-consuming and labor-intensive, the infusion pressure fluctuates greatly, the operation is frequent, a blood bag / liquid bag needs to be bagged when used, a residual gas is left in thebag after closed, and at the time, a pressure-filling operation on the blood bag / liquid bag is more inaccurate are solved. The equipment comprises a casing, a fixing clip and two pressurizing bags, the two pressurizing bags are respectively connected to two sides of the casing through quick-connecting plugs, the inside of the casing is connected with an inflating pressure relief device through arubber pipe, the rubber pipe includes two four-way connecting pipes, two three-way connecting pipes and two silicone pipes, and the inflating pressure relief device includes a plurality of connected single bodies.

Description

technical field [0001] The invention relates to the fields of medical blood transfusion and pressure transfusion, in particular to a stable pressurizing device for medical emergency blood transfusion and transfusion bags. Background technique [0002] At present, clinically, the method of increasing the suspension height of the infusion bag and manually squeezing the soft packaging liquid bag is mainly used to achieve the purpose of rapid infusion of liquid. The emergency operating room in the hospital mainly uses a hand-held air bag for pressurization. Unstable, resulting in large fluctuations in flow rate, and damage to red blood cells, thereby delaying rescue. [0003] When a patient loses a lot of blood, blood must be replenished quickly, but the maximum natural flow rate of a normal blood transfusion / infusion set cannot meet the requirements for rapid infusion. Medical institutions at home and abroad use rapid pressurized blood transfusion / infusion for the rescue of pat...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a stable pressurization device for medical emergency blood transfusion and infusion bags, which can solve the problem that the device used is to hold a balloon in the hand to inflate the pressurized bag, which requires multiple extrusion operations, which is time-consuming and laborious. The volume of the bag / liquid bag decreases with the duration of the infusion, and the infusion pressure decreases, requiring personnel to manually replenish the pressure. Blood bags and liquid bags have different sizes such as 200mL, 300mL, 500mL, 1000mL, 3000mL, etc. The manual operation pressure fluctuates greatly , is not conducive to safe and rapid infusion. Blood transfusion and infusion use gravity or manual pressurized bags in the operating room and ICU. It needs to be bagged and used, and there is still gas inside the bag after it is closed. At this time, it is even more inaccurate to perform pressure supplementation on the blood bag / liquid bag
