Safety-protection infusion apparatus

Abstract

The invention provides a safety-protection infusion apparatus. The safety-protection infusion apparatus is characterized in that an air sterilizer is arranged on an air tube and can sterilize bacteria and viruses in outside air; a diaphragm net capable of forming a water surface tension is arranged in a dropper, and can automatically stop flowing of a medicine liquid after infusion is completed so as to avoid situations that air enters the vein and the blood returns; a dripping speed warning device is arranged outside the dropper, can automatically calculate the dripping speed, and can give an alarm when the dripping speed exceeds a preset upper limit and a preset lower limit; a dripping speed regulator has a locking function to avoid the potential safety hazard caused by dripping speed regulation without permission; a needle accommodating sleeve is arranged on a thin infusion tube, and can accommodate a puncture needle, which is pulled out after the infusion is completed, in the sleeve so as to effectively prevent accidental puncture from occurring; a needle handle and a puncture needle fixer are arranged on the puncture needle, the needle handle is perpendicularto the puncture needle, and the puncture needle fixer is matched with the needle handle, so that a situation of puncture needle removal or medicine liquid extravasation can be prevented from occurring.

[0002] Infusion is an important means of hospital treatment. At present, when patients are given intravenous infusion, a large number of disposable infusion sets are used, which has a certain effect on preventing cross-infection, but there are also many safety hazards

[0003] ①Existing infusion sets rely on atmospheric pressure infusion, and need to continuously replenish air into the infusion bottle. The air floats through the liquid in the form of bubbles to the top of the liquid surface. However, in the special environment of the hospital, there are many types of pathogenic microorganisms in the air, including bacteria. The air passes through the liquid medicine, and the liquid medicine becomes an air filter fluid, and the dust and bacteria in the air are all integrated into the liquid. Patients often have adverse reactions and even cross-infection when they enter this heavily polluted liquid.

[0004] ②Currently, clinically, the liquid level in the infusion set needs to be monitored during the clinical infusion process. If the infusion is not processed in time, blood will return, and in severe cases, air will enter the venous blood vessels and form an air embolism.

Due to the inclined structure of the frame and the smoothness of the infusion tube, the adjustment wheel is easy to loosen, resulting in changes in the drip rate; in addition, the drip rate regulator is open, and patients and their families often adjust the drip rate for different reasons. Or diseases need to strictly control the drip rate, otherwise it is easy to produce adverse reactions and unpredictable consequences

[0007] ⑤ After the existing disposable infusion set is used, the puncture needle is exposed, which is easy to puncture the nursing staff or others. According to statistics, there are about 1 million nursing staff in the world who suffer from acupuncture injury accidents every year, which will cause at least 20 kinds of diseases. One of the main risk factors for occupational injury in nursing staff

[0008] ⑥The needle handle of the existing disposable infusion set and the puncture needle are on the same plane. When in use, two fingers are pinched up and down the needle handle. Since there are fingers under the needle handle, the angle between the puncture needle and the skin is relatively large, and the needle handle is fixed after puncture Pressing down will change the original direction of the puncture needle, which will easily cause the puncture needle to puncture the blood vessel. Some nurses put cotton balls under the needle handle in order to maintain the original puncture direction, but this will increase the instability of the puncture needle. The existing needle handle is not easy to hold and force, and it is inconvenient to operate

[0009] ⑦ At present, adhesive tape is commonly used to fix the puncture needle during infusion. Due to the flexibility of the adhesive tape, the effect of adhesive tape on fixing the puncture needle is not good, especially for children who are easy to move, and the puncture needle often rolls and punctures the blood vessel wall, causing liquid extravasation or the puncture needle falls off.
