Automatically drip-stopping and alarm device for infusion device

Abstract

The invention relates to an automatic drop stopping alarming device for an infusion apparatus, which comprises a puncture outfit, a power assisted air sac, a connecting pipe of gas and liquid guiding and an upper cover of a liquid gathering pipe; among which, a connecting part and an elastic sealing sleeve are arranged at the lower interface of the liquid gathering pipe which is internally provided with a hollow floater, and the upper end and the lower end of the hollow floater are respectively provided with an upper guide bar and a conical plug which is provided with a lower guide bar at the lower end of the conical plug. The upper guide bar and the lower guide bar are respectively inserted into a guide hole and the connecting part on the upper cover of the liquid gathering pipe; the upper surface of the hollow floater is a conical surface and a magnetic body is arranged on the hollow floater; a sound-light alarming device internally provided with a reed switch or a magnetic switch is arranged outside the liquid gathering pipe; the reed switch or the magnetic switch is corresponding to a falling position of the magnetic body. The automatic drop stopping alarming device has the advantages that the alarming device is simple in structure and reliable in work; when the infusion is almost over, the infusion automatically stops and closes, and the vessels of the infusion patients do not have blood returning or take in air and have the function of automatic alarming, which facilitates patients and accompanying persons to get the information of infusion ending in time and the infusion apparatus can be turned off automatically immediately to prevent the occurrence of medical accidents.

Description

technical field [0001] The invention belongs to an automatic control device, in particular to an automatic drip stop and alarm device for an infusion set. Background technique [0002] The existing infusion set alarm device is composed of a liquid collecting pipe, a drip bucket, a float arranged in the liquid collecting pipe and containing magnetic powder, a reed switch arranged on the side wall of the liquid collecting pipe, a power supply and an alarm device connected in series with the reed switch. . When the infusion is finished, the float moves down to make the reed switch act, and the alarm device is connected, and the alarm device is set in the nurse's duty room. The problems of this kind of alarm device are: 1. The float cannot close the liquid outlet of the collecting tube when the infusion is exhausted, and it cannot prevent the air from entering the blood vessels and the phenomenon of blood returning to the patients who are in the sleeping state or the deaf and m...

AI Technical Summary

Problems solved by technology

The problem that this alarm device exists is: 1, floater can not be closed with the liquid outlet of collecting pipe when infusion is waited to the end, can not prevent the medical accidents such as air entering blood vessel and returning blood phenomenon to the patient who is in sleep state or the deaf-mute occur

2. The upper surface of the float is flat, so that the residue of the liquid medicine is wasted, which does not meet the requirements for infusion

3. Since the float has no guiding device, the float shakes with the liquid medicine, so that the magnetic powder is in a floating state, and the reed switch does not work stably, so it cannot provide an accurate alarm.

4. The alarm device is installed in the nurse's duty room, and wiring needs to be added, which not only increases the investment, but also makes the ward look messy, and the patient or accompanying staff cannot get the information that the infusion is pending in time; The monitoring personnel first get the information, and then notify the nurses. The processing process is cumbersome. In addition, the nurses sometimes cannot arrive in time due to other affairs, which delays the processing time and easily leads to medical accidents.
