Embodiment Construction

[0007] A disposable pressure infusion and blood transfusion device shown in Fig. 1 . It consists of two parts: the pressure infusion and regulation system and the pressure generation and observation control system. The pressure infusion and regulation system consists of a liquid bag 1, an infusion hose 2, an infusion speed regulator 3, a self-venting filter 4, and an infusion puncture needle assembly 5; the pressure generation and observation control system consists of a liquefied gas cylinder 6, a liquefied gas release Consists of a speed regulating valve 7, a liquid phase bubble observer 8, a connecting hose 9, and an air pressure bag 10;

[0008] During the treatment, add the liquid medicine and connect the pressure infusion and regulation system with the pressure generation and observation control system in sequence, and then perform the puncture. Open the liquefied gas release speed regulating valve 7, the liquefied gas enters the air pressure bag 10 through the liquid p...

Abstract

The present invention provides a one-off pressure infusion and transfusion device, which comprises two parts that are a pressure infusion and regulation system and a pressure production, observation and control system. The pressure infusion and regulation system comprises a liquid bag, an infusion hose, an infusion speed regulator, a self-discharge filter and an infusion puncture needle module; the pressure production, observation and control system comprises a liquid gas steel bottle, a liquid gas discharge speed regulating valve, a liquid phase bubble observer, a connecting hose and a pressure bag; wherein, the liquid bag of the pressure infusion and regulation system and the pressure bag of the pressure production, observation and control system are integrated into a whole. When in infusion, the liquid gas discharge speed regulating valve is opened, so that the liquid gas enters into the pressure bag by the liquid phase bubble observer and the connecting hose, so as to expand and then transfer the pressure to the liquid bag. The liquid in the liquid bag enters into the body of the patient by the infusion hose, the infusion speed regulator, the self-discharge filter and the infusion puncture needle module.

Description

technical field [0001] The invention relates to a pressure transfusion and blood transfusion device, which can be widely used for transfusion treatment in complex environments. Background technique [0002] Today's infusion and blood transfusion sets are mainly gravity-type, that is, the power of infusing liquid comes from the gravity energy of the liquid itself. The device includes: infusion bottle (bag), infusion needle, drip funnel, catheter, infusion speed regulator, filter, puncture needle and the like. When performing infusion, liquid enters the human body from an infusion bottle (bag) through an infusion needle, a drip funnel, a catheter, an infusion speed regulator, a filter and a puncture needle, so as to achieve the purpose of treatment. But such infusion always can't get rid of the restriction that infusion bottle is placed on the patient's body position, is not suitable for rescue occasions in the field, 120 first aid and disaster. For this reason, Chinese pate...
