Automatic medicine injection device for switching between pain-relieving state and anti-blocking state

Abstract

The invention provides an automatic medicine injection device for switching between a pain-relieving state and an anti-blocking state, which comprises a first medicine liquid bag for storing first liquid medicine; a second liquid medicine bag used for storing second liquid medicine; a liquid medicine switching conduction part communicated with the first liquid medicine bag through a first pipeline, communicated with the second liquid medicine bag through a second pipeline and further communicated with an input port of the infusion tube, wherein the state that the first liquid medicine bag is communicated with the infusion tube is the pain-relieving state, and the state that the second liquid medicine bag is communicated with the infusion tube is the anti-blocking state, and the liquid medicine switching conduction part is configured to control the automatic medicine injection device to be switched between the pain-relieving state and the anti-blocking state according to a preset instruction. The non-analgesic liquid medicine can be continuously infused when the analgesic liquid medicine is not infused, the phenomenon that an infusion pipeline is blocked due to blood coagulation possibly caused by stopping infusion of the liquid medicine is effectively eradicated, then the situation that an infusion channel is opened due to re-injection is avoided, the satisfaction degree of a patient can be improved while time and labor are saved, and the medical experience is good.

Description

Technical field [0001] The present invention belongs to the technical field of medical device, and more particularly to an automatic injection device for switching between analgesic state and a blocked plug state. Background technique [0002] Electronic infusion pump is widely used in postoperative analgesic and pain treatment, and traditional infusion is set to set an hourly infusion, and the electronic infusion pump is continuously infused according to the amount of setting, and the patient The degree of pain in different time periods is different, sometimes there is no need to infuse the town pain, and the way such continuous infusion is relatively, the drug solution is relatively, and the drug solution is more negative, the patient The satisfaction is not high. Based on the foregoing state, a plurality of pickers (drug vesa) infusion devices have a plurality of pickers (drug veins) can be turned on by controlling each drug foot and the infusion tube, respectively, respective...

Problems solved by technology

[0002] Electronic infusion pumps are widely used in postoperative analgesia and pain treatment. The traditional infusion method is to set the infusion volume per hour, and the electronic infusion pump will continuously infuse according to the set volume, while the patient The degree of pain experienced in different time periods is different, and sometimes there is no need to infuse analgesic liquid, and such a continuous infusion method uses relatively more liquid medicine, and there are many adverse reactions to the liquid medicine. low satisfaction

Based on the aforementioned situation, an infusion device with multiple medicine boxes (medicine capsules) has appeared in the prior art, which can control the sequential conduction of each medicine capsule and the infusion tube, so that each medicine capsule can be administered sequentially. liquid supply (medicine solution infusion in one capsule automatically enters the next capsule after infusion), which greatly facilitates medical staff and patients, but this method of sequential infusion cannot give patients The way of self-control according to the degree of pain of oneself, that is, the infusion of the corresponding analgesic liquid can be automatically disconnected after the patient feels the pain is reduced. This is because the multi-drug capsule in the prior art does not have the continuous Supplementary infusion function, which will cause the patient to disconnect the analgesic solution during the infusion period, that is, outside the patient's self-controlled infusion period, no liquid continues to enter the patient's blood vessels, and it is easy to cause blockage of the infusion line due to blood coagulation

Once blocked, it is often necessary to re-inject and open the infusion channel, which is time-consuming and labor-intensive, and patient satisfaction is greatly reduced
