Background technique

Medical infusion is a very commonly used treatment method in medical activities. During the infusion process, it is usually observed by medical staff, patients or companions, and the infusion bottle is replaced in time or the needle is pulled out to end the infusion. Due to the large number of infusion patients, the medical staff often cannot know in time whether the patient needs to replace the infusion bottle or has completed the infusion. At the same time, the patient or companion cannot timely notice the situation of the liquid medicine in the bottle due to various reasons, so that the medical staff cannot be notified in time to replace the infusion bottle. Or end the infusion process, so often there will be blood return, and even endanger the health and safety of the patient.

Contents of the invention

The object of the present invention is to provide a kind of medical transfusion alarm device, the medical transfusion alarm device of the present invention is by arranging the sampler at the bottom of the infusion bottle, the bag or the top position of the infusion output pipe, monitors the state of the liquid, and reports to the police in time through the control equipment, Therefore, the medical staff can timely control the replacement of the transfusion and end the transfusion process.

The purpose of the present invention can be achieved through the following technical solutions:

A medical infusion alarm device, including a sampler, a control device and an alarm device, the control device includes a sampling connection wire, a power switch, a power supply, a signal processing unit, an alarm output unit, an alarm output line and an alarm connection line, the There are two sampling needles on the sampler. The alarm device includes an internal alarm device and an external alarm device; The device connection line is connected with the alarm device, and the power supply, switch, signal processing unit, and alarm output unit are connected through wires in turn; the alarm output unit is connected to the peripheral alarm output line, and the alarm output unit has two outputs, one output To the external alarm device, one output to the internal alarm device.

The control device is a device with low conduction voltage; the power supply is powered by power input or a built-in battery.

The alarm device is a photoelectric alarm.

The alarm device can be built into the control device.

The sampling needle is made of medical-grade metal material, and the interface is made of engineering plastics.

The direction of the interface is 90o to the sampling needle.

The sampling needle is conductive metal.

Compared with the prior art, the present invention has the beneficial effects of:

(1) The medical infusion alarm device of the present invention has a simple device structure. When in use, only the sampling needle is sterilized and inserted into the upper end of the infusion system. It is convenient and simple, and will not affect the safety of the infusion system.

(2) The medical infusion alarm device of the present invention has a simple steady-state circuit structure and good stability, and the level output can be used as an alarm alone, or can be connected to other alarm systems or call systems for use.

(3) The medical infusion alarm device invented can play an alarm role in time when the infusion is completed or the infusion bottle needs to be replaced, and the corresponding sound can be emitted to attract medical staff and patients to notice the change of the liquid level in the infusion bottle in time, so as to take timely measures. Appropriate measures.
