Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a disposable infusion set with an automatic exhaust precision filter. Background technique [0002] With the passage of time, human beings continue to develop new drugs, but the bacterial resistance to various diseases that threatens human beings is also increasing, and viruses are also constantly mutating, making it more difficult for humans to treat various diseases In the past, diseases that could be treated by taking medicine in the past now need intramuscular injection or infusion to treat. Therefore, intravenous infusion has become one of the most common and effective methods of administration in modern clinical treatment. During the infusion operation of the patient, it is often encountered that there is air in the infusion set. If the air in the infusion tube is not exhausted or the rubber tube device is not tight, the air enters the patient's blood and may form a pulmonary...

Problems solved by technology

During the infusion operation of the patient, it is often encountered that there is air in the infusion set. If the air in the infusion tube is not exhausted or the rubber tube device is not tight, the air enters the patient's blood and may form a pulmonary embolism. The patient's life is endangered. Therefore, the air in the infusion tube needs to be removed. The traditional low-end infusion set encounters this kind of situation. The air in the tube moves up to the Murphy dropper, and then continues to move down to bounce; 2. Use the downward exhaust method, that is, separate the scalp needle, discharge the air from the end of the infusion set, and then connect the scalp needle, but this method 3. The upper row winding method, that is, close the liquid circuit, start from a point about 20-30cm below a certain section of the infusion tube with air bubbles, and while pinching the infusion tube with the right thumb and index finger Wrap the pinched infusion tube tightly around the index finger of the left hand until the liquid level reaches the Mophy dropper, release the right hand, squeeze the Murphy dropper to make the liquid level reach 1 / 2 to 2 / 3 of the Mophy dropper, and then Slowly loosen the infusion tube wrapped around the left hand, check that there are no air bubbles in the tube, and adjust the liquid path to the required number of drops; the above method is both troublesome and easy to start the injection for the second time, which will cause secondary damage to the patient
