Embodiment Construction

[0016] The solar infusion alarm of the present invention is made up of battery, alarm and spring balance, and wherein on the spring balance, the fixed bar-shaped conductor sheet is used as static contact sheet, and the reading sheet of spring balance is used as moving contact sheet, and moving contact sheet, static contact sheet, alarm and battery They are connected in series to form a circuit, and the alarm is an electronic circuit breaker alarm. When the moving contact piece and the static contact piece are in contact, the alarm works and sends out an alarm sound.

[0017] The implementation steps of a manufacturing method of a solar infusion alarm are as follows:

[0018] 1) Measure the position of the empty infusion bottle with a spring balance and mark it as point A;

[0019] 2) Measure the position of the full infusion bottle with a spring scale and mark it as point B;

[0020] 3) Fix the iron piece on the spring balance from point A to point B as a static contact piece...

Abstract

The invention relates to a solar transfusion alarm, which consists of a battery, an alarm body and a spring scale. Application steps include marking the position, which is measured by the spring scale, of an empty transfusion bottle as a point A; marking the position, which is measured by the spring scale, of a full transfusion bottle as a point B; fixing a conductor plate used as a fixed contact from the point A to the point B on the spring scale; adopting a degree iron plate on the spring scale as a movable contact; connecting one lead on the alarm body to the fixed contact while connecting another lead on the alarm body to the movable contact; respectively connecting two poles of the solar battery to the fixed contact and the movable contact; and switching off a circuit when the liquid in a transfusion bottle is gradually consumed until the point A and the point B on the spring scale contact with each other, and then making an alarming sound by the alarm body. In the technical scheme, the solar transfusion alarm can remind a transfusion patient of paying attention to the change of liquid level.

Description

technical field [0001] The invention relates to an alarm, in particular to a solar infusion alarm used for alarming during infusion. Background technique [0002] At present, there are many kinds of alarms, most of which are used for safety precautions. They can be divided into mechanical alarms and electronic alarms. The alarm mainly uses the existing telephone network or wireless mobile phone GSM.GPS network to connect to the owner's phone or mobile phone through wireless or wired methods to realize the remote anti-theft function of electronic products. [0003] Currently popular products on the market mainly consist of a signal-receiving anti-theft host and a series of police detectors. Such as infrared detectors, door magnets, smoke detectors, infrared fences. For simple alarms, especially for effectively detecting infusion, it is impossible to use the above-mentioned alarm with specific functions to detect the change of liquid level during infusion so as to achieve m...
