Blood transfusion and infusion pressurization method and device for implementing same

Abstract

The invention discloses a blood transfusion and infusion pressurization method, comprising the following steps: 1. arranging an air bag and a guide pipe; 2. arranging a piezometer; 3. arranging an inflation device; 4. arranging a controlling air device at the connection part of the inflation device so as to control air inlet of the inflation device and exhaust of the air bag. The invention also discloses a device for realizing the method; the method provided by the invention can finish pressurization fast, evenly and accurately; the device provided by the invention has simple structure and convenient operation, can realize pressurization to a storage bag in a supporting cavity only in need of starting the inflation device to inflate air to the air bag, and is provided with an air controlling device for controlling pressure accurately, safely and reliably, and the use safety is ensured; the adopted piezometer can accurately display air pressure in the air bag, and two ends of the outershell thereof are provided with transparent parts which are convenient for observing pressure parameters in all aspects.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a blood transfusion pressurization method and a device for implementing the method. Background technique [0002] At present, in the clinical operation and rescue of shock patients or critically ill patients, the patient's blood volume is seriously insufficient or the function of some organs is reduced, resulting in peripheral circulation failure. Even if the venipuncture is successful, it is difficult to rely on normal blood transfusion or infusion speed In order not to delay the rescue and treatment of the patient, rapid blood transfusion or infusion should be performed on the patient. [0003] The existing rapid pressurized blood transfusion and infusion devices generally include rapid pressurized blood transfusion infusion pump, three-way pressurized blood transfusion infusion, direct blood transfusion, air pressurized blood transfusion, infusion, etc. in ...

AI Technical Summary

Problems solved by technology

For example, the blood transfusion infusion pump is cumbersome to use, and it is easy to block the blood transfusion hose, and the mechanical friction is large, which seriously damages the red blood cells; the three-way blood transfusion infusion device needs to use a syringe to continuously pressurize and inject blood. Because the syringe piston slides back and forth, the blood It is easy to attach to the plunger, so each syringe can only be injected several times, and another syringe needs to be replaced after a dozen times at most

Repeated injections of blood and frequent replacement of syringes have a greater chance of contamination of the blood; if the blood transfusion bottle is directly injected with air to pressurize, there will be many inconveniences during operation, and the conditions are high, so it is necessary to beware of liquid contamination at any time

Although a pressurized bag has been introduced in the foreign market recently, its structure is complicated, the operation is cumbersome, the inflation is laborious, the exhaust is not fast enough, the instrument data error is large, and it is not easy to observe, and it cannot achieve fast, uniform and accurate pressurization and exhaust reduction. Purpose

In addition, there is no safety protection device. If the pressure in the airbag exceeds the limit due to the medical staff's misoperation, the pressure cannot be automatically released.
