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.

Embodiment Construction

[0012] Such as figure 1 As shown, the present invention has a puncture device 3, one side of the puncture device 3 is provided with a liquid guide hole 301, the other side is provided with an air guide hole 302, the air guide hole 302 is provided with an air inlet 302a, and the air guide hole 302 is located at the air inlet The part below 302a is the lower airway, and the air guide hole 302 is located above the air inlet 302a and is the upper airway. The positions of the upper airway and the lower airway are alternate. The air guide passage of 2 communicates with the air guide hole 302 and slopes downward along the direction of the air inlet 302a of the air guide hole 302, so as to prevent the liquid medicine entering the booster air bag 2 from being able to completely return during operation. An air filter 1 is installed on the booster airbag 2, an air guide and a liquid guide connecting tube 4 are connected to the lower port of the piercer 3, and a liquid collecting tube wit...

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 ...
