Automatic transfusion alarm system

Abstract

The invention relates to an automatic transfusion alarm system, which comprises a transfusion bottle, an alarm buzzer, a capacitive proximity switch, an alarm circuit, an alarm resetting circuit and a single-chip microcomputer. The probe of the capacitive proximity switch is arranged above a bottle opening on the lower part of the transfusion bottle, the capacitive proximity switch is connected with the alarm circuit, and the alarm circuit, the alarm resetting circuit and the alarm buzzer are respectively connected with the single-chip microcomputer. When the liquid level in the transfusion bottle is lower than the probe of the capacitive proximity switch, liquid level change signals can be detected by the capacitive proximity switch through the probe and can be converted by the capacitive proximity switch into alarm conduction signals to trigger conduction of the alarm circuit, and when the alarm buzzer can be controlled to alarm when the conduction of the alarm circuit is detected by the single-chip microcomputer. The invention has the advantages that: automatic transfusion alarming can be achieved, blood return and other situations caused by the reason that the transfusion of liquid medicine in the transfusion bottle is completed due to human errors can be avoided, and the automatic transfusion alarm system can be used safely and has low cost.

Description

technical field [0001] The invention relates to a transfusion alarm system, in particular to an automatic transfusion alarm system. Background technique [0002] Infusion therapy is the most common treatment method used in hospitals. The more infusion alarm that the hospital uses at present is that the alarm button is placed on the infusion chair. When the infusion is about to be completed, the patient presses the button to call the police. This alarm system has the following disadvantages: [0003] 1. Infusion patients tend to fall asleep due to long-term infusion, and because of negligence such as chatting and reading, it is easy to cause the infusion bottle (bag) to run out of medicine and not to call the police. increase patient suffering; [0004] 2. Due to the high hanging of the infusion bottle (bag), some patients with poor eyesight, especially the elderly, cannot see the progress of the infusion clearly. the circumstances of the alarm; [0005] 3. At present, t...
