Transfusion system capable of conveniently and accurately monitoring transfusion flow

Abstract

The invention belongs to the technical field of transfusion, and relates to a transfusion system capable of conveniently and accurately monitoring the transfusion flow. The transfusion system includes a liquid drug container, a transfusion pipe and a flow monitoring device, wherein the liquid drug container is used for containing liquid drugs and is connected with the transfusion pipe, and the flow monitoring device is arranged on the transfusion pipe and used for monitoring the transfusion flow; the other end of the transfusion pipe is connected with vein vessels of a patient, so that the liquid drugs can flow into the vein vessels of the patient; the flow monitoring device includes a housing, a liquid drug inlet, a valve element, an elastic part and a liquid drug outlet, wherein the liquid drug inlet, the valve element, the elastic part and the liquid drug outlet are sequentially arranged in the flowing direction of the liquid drugs in the housing; a gap is formed between the valve element and the housing and / or an opening is formed in the middle of the valve element, so that the liquid drugs can flow through the flow monitoring device. By means of the transfusion system capable of conveniently and accurately monitoring the transfusion flow, time, labor and worry are saved, and the transfusion flow in the transfusion process of the patient is accurately monitored.

Description

technical field [0001] The invention belongs to the technical field of infusion sets, and relates to an infusion system capable of conveniently and accurately monitoring infusion flow. Background technique [0002] Intravenous infusion therapy is a treatment method that injects drugs or blood into the human blood circulation system. With the development of science and technology, the traditional infusion method has been greatly improved, and the infusion pump has gradually entered the hospital, allowing people to control the infusion more accurately, making medication safer, and at the same time making nurses more worry-free during the infusion process Save effort. However, whether it is the traditional infusion method or the infusion method of the infusion pump, the infusion flow is monitored through the action of gravity, which makes the infusion set longer in length and inconvenient to move. More importantly, both infusion methods are not convenient for medical staff an...

Problems solved by technology

[0004] The disadvantages and problems of the above-mentioned infusion system relying on gravity include: 1) the liquid medicine container must be placed at a high place, relying on the gravity of the liquid to generate a pressure difference to make the liquid medicine flow out; 2) the nurse needs to place the drip pot vertically, It is time-consuming and labor-intensive to calculate the number of droplets, and then estimate the flow rate of the liquid medicine; 3) Since the liquid medicine container needs to be hung high, the infusion tube is usually very long, and more materials are used

[0006] The disadvantages and problems of the above infusion system relying on the infusion pump include: 1) It is still necessary to stand the drip pot vertically and detect the infusion flow by counting the number of drops of medicine, so it will be very inconvenient in emergency situations such as moving or field rescue ; 2) It is still necessary to hang up the liquid medicine container, so the infusion tube will still be very long, and more materials will be used

This is not only time-consuming and laborious, but also the accuracy of flow measurement is not high.
