Abstract

Venous transfusion blood return and over low temperature of liquid medicine for venous transfusion are medical accidents which are caused by loose custody and occur easily in medical treatment, and can cause severe secondary harm to patients. Possibility of occurrence of venous transfusion blood return accidents is higher especially on the conditions that a hospital is in patient transfusion rush hours and the number of caring workers is not enough. The venous transfusion blood return accident is a big difficult problem for the hospital. In order to solve the difficult problems in venous transfusion and overcome the technical defects of an existing product, the invention provides a novel venous transfusion switching and alarming device. A simple and ingenious mechanical structure design is adopted for the device. Reduction of the self weight of an infusion bottle is utilized to control connection and disconnection of two contacts, and then connection and operation of an indication light, a micro-alarm and a stepping motor are controlled, so that stoppage of venous transfusion is controlled, and medical workers and patients are alarmed. The device is simple and ingenious in design and high in reliability, and brings great convenience to monitoring of venous transfusion of the patients.

Description

technical field [0001] The invention relates to an automatic device for medical monitoring, in particular to a novel intravenous infusion switch and an alarm device. Background technique [0002] As we all know, blood return from intravenous infusion is a kind of medical accident caused by poor monitoring that is very likely to occur in medical treatment, and it will cause serious secondary injuries to patients. Especially when the hospital is in the peak period of patient infusion, there are not enough guardians or the care of medical staff is not good enough, the possibility of blood return accidents in intravenous infusion will be greater; There are few relevant technical measures, which not only consumes manpower and energy, but also has unsatisfactory monitoring effect. All these will bring a lot of inconvenience in monitoring and management to hospitals or clinics. [0003] In view of the infusion alarm devices that have appeared in recent years, such as automatic in...
