Problems solved by technology

[0003] In the prior art, when the above process is carried out, it is realized manually. This method has a large human negligence factor, which is likely to cause accidents such as backstitching.
[0004] Chinese patent application 201010225967.1 discloses an intelligent intravenous infusion monitoring system, which connects various devices through Ethernet to realize infusion monitoring, but its structure is complicated; Chinese patent application 201120298828.1 discloses a wireless infusion monitoring system, its A variety of devices are connected through wireless devices to achieve real-time understanding of the infusion progress of each patient, but the system is complex and has low practicability; Chinese patent application 201210112636.6 discloses an automatic controller for intravenous infusion levels in medical hanging bottles and Its control method realizes the monitoring of the liquid level in the hanging bottle through a light emitter and two photosensitive receiving tubes. This system has low practicability, is greatly affected by light, and it is difficult to fix the liquid level. The conversion operation is complicated, the margin error is large, and the response time reserved for the medical staff based on the early warning of the drip is short. At the same time, the patent document does not mention how to change the liquid automatically; Chinese patent application 201210078804.4 discloses an automatic control infusion device and Its automatic control method, its core is to realize the control by squeezing the infusion tube with the disc roller, the structure is relatively complicated, the production and assembly of the equipment is complicated, and the flow rate is not easy to control, and the volume is large
[0005] Therefore it can be seen that there are many defects in the prior art, and a kind of comparatively practical infusion system does not exist

Abstract

The invention provides an automatic transfusion liquid switching system and belongs to the field of medical equipment. The automatic transfusion liquid switching system comprises an outward turning type rotatory liquid switcher, transfusion bottles, a driving unit and a control system, and the control system can control the driving unit to drive a shell of the outward turning type rotatory liquid switcher to rotate so as to complete switching of the transfusion bottles. By the automatic transfusion liquid switching system, automatic switching of the transfusion bottles can be realized, switching of the transfusion bottles is unaffected by factors such as human negligence, risk caused to patients in the process is lowered, medical negligence is reduced, medical efficiency is improved, and development of the medical industry is promoted.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an automatic transfusion fluid replacement system. Background technique [0002] Infusion is a treatment process that almost everyone has experienced. In severe cases, doctors generally prescribe multiple bottles (or bags) of injections for patients, and patients inject the injections into the vein one after another during infusion. In this case, after the injection of the previous bottle of injection is completed, the next bottle of injection needs to be replaced for injection. [0003] In the prior art, when the above process is carried out, it is realized manually. This method has a large factor of human negligence, which may cause accidents such as backstitching. [0004] Chinese patent application 201010225967.1 discloses an intelligent intravenous infusion monitoring system, which connects various devices through Ethernet to realize infusion monitoring, but its structure i...
