Liquid stop alarm device

Abstract

The invention relates to a transfusion device, in particular to a liquid medicine and blood transfusion liquid stop alarm device which can realize timely sensing and exhaust, belonging to the technical field of medical appliances. The liquid medicine and blood transfusion liquid stop alarm device comprises a transfusion hose, a dropper and a puncture needle. The puncture needle is arranged at the upper part of the dropper. A liquid outlet is formed in the lower part of the dropper. The puncture needle is used for being connected with a transfusion bottle. The liquid outlet is connected with the transfusion hose. A safety valve is arranged in the dropper. The inner diameter of the safety valve is smaller than the inner diameter of the dropper. A connector is arranged at the connecting position between the transfusion hose and the liquid outlet. The connector is used for being communicatively connected with the transfusion hose and the liquid outlet. An air inlet which can be controlled to be opened and closed is formed in the connector. The liquid medicine and blood transfusion liquid stop alarm device provided by the invention not only can prevent blood from returning, but also can enable liquid medicine to be fully transfused and prevent waste, and is of a great significance to the transfusion of expensive liquid medicine such as anti-tumor medicine.

Description

[0001] This application is a divisional application of an invention patent application with an application date of 2012.06.21, an application number of 201210207387.9, and an invention title of a hemostasis alarm device for transfusion transfusion. technical field [0002] The invention relates to an infusion device, in particular to an infusion transfusion hemostasis alarm device capable of timely sensing exhaust, and belongs to the technical field of medical devices. Background technique [0003] In the prior art, in order to prevent the backflow of blood or air entering the blood vessel after the infusion of the medicinal liquid during clinical infusion, devices such as floating valves or floating plugs are usually installed in the dropper of the infusion set. Devices such as valves or floating plugs block the liquid outlet of the dropper with the sinking of the medicinal liquid, thereby effectively blocking the liquid from the dropper. [0004] In the prior art, the Chin...
