Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0016] Because the infusion pump cannot normally control the flow rate of the medicinal liquid in the infusion tube when the pressure of the pump body is insufficient, the medicinal liquid will quickly enter the patient's body, causing a great hidden danger to the life safety of the patient. Based on this, an embodiment of the present invention provides an infusion system to better solve the current problem of out-of-control flow rate of medicinal liquid. The prese...

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...
