Transfusion system

Abstract

The invention provides a transfusion system, which comprises a transfusion pump and a transfusion tube, and further comprises a liquor stopping device positioned downstream the transfusion pump, wherein the liquor stopping device provides prestress so as to be in a normally closed state of blocking the transfusion of the transfusion tube; and only when the transfusion tube normally works, a pressure provided by the transfusion tube is counterbalanced with the prestress, so that the liquor stopping device is in an open state of making the transfusion tube at work. The transfusion system can solve the problem of the uncontrollable liquor flow velocity of the transfusion pump in the prior art.

Description

technical field [0001] The invention relates to the field of medical science and technology, in particular to an infusion system. Background technique [0002] Infusion is one of the important treatment methods in clinical medicine. The infusion pump is an automatic infusion device with an infusion set as a consumable. The infusion pump body, the power part of the infusion pump, periodically squeezes the infusion line to control the infusion of the drug into the patient. velocity in the body. Compared with the traditional bottle infusion method, the infusion pump has the characteristics of high precision, wide flow rate range, and can provide greater positive pressure. [0003] Since the infusion pump body is a mechanical moving part, there must be problems such as wear and aging in actual use. In addition, due to the batch differences of infusion sets and the influence of ambient temperature on the hardness of infusion sets, the infusion pump has the risk of out-of-control...
