Automatically drip-stopping and alarm device for infusion device

Abstract

An automatic drip stop and alarm device for an infusion set, including a puncture device, a power-assisted air bag, an air guide and a liquid guide connecting tube, an upper cover of a liquid collection pipe, a connecting piece and an elastic sealing sleeve at the lower port of the liquid collection pipe, and a There is a hollow float in the tube, the upper and lower ends of the hollow float are respectively provided with an upper guide rod and a tapered plug, and the lower end of the tapered plug is provided with a lower guide rod, and the upper and lower guide rods are respectively inserted into the guide hole on the upper cover of the liquid collection pipe and connected Inside, there is a magnetic body on the hollow float, and an audible and visual alarm device with a dry reed switch or a magnetic switch inside the liquid collection pipe. The dry reed switch or magnetic switch corresponds to the falling position of the magnetic body, and the hollow float The end face is a tapered surface, and its special feature is that the positions of the upper airway and the lower airway of the trocar are staggered. The advantages are: simple structure and reliable operation. When the infusion is finished, it can be automatically closed and the drip will be stopped automatically. The blood vessel of the infusion patient will not return blood and air will not enter. And the infusion set can be closed immediately by itself to prevent medical accidents from happening.

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 device alarm device is composed of a liquid collecting pipe, a dripping funnel, a float installed 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 connected in series with the reed switch, and an alarm device. . When the transfusion is waiting to be exhausted, the float moves down to make the reed switch act, and the alarm device is connected, and the alarm device is located in the nurse's duty room. 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 ...
