Description
Technical Field
The utility model relates to the field of medical appliances, in particular to a disposable automatic exhaust and liquid stop infusion apparatus.
Background
At present, when a hospital carries out intravenous infusion or blood transfusion on clinical patients, a disposable infusion apparatus is generally used, so that the disposable infusion apparatus plays a beneficial role in preventing cross infection among the patients. However, the disposable infusion apparatus has the disadvantages that after the liquid medicine is infused, the disposable infusion apparatus needs to replace a liquid medicine bottle (bag) or pull out an infusion needle in time because of no automatic interception function, otherwise air enters an infusion catheter to bring unsafe factors to patients, and the disposable infusion apparatus is not beneficial to the treatment of clinical patients; in addition, when the liquid medicine in the infusion apparatus begins to enter the dropping funnel, a mixture of gas and liquid is very easily formed, the gas-liquid mixture can rapidly enter the infusion pipeline below the dropping funnel, a bubble phenomenon during infusion is formed, and the health of a patient is threatened, so that medical staff need to completely discharge bubbles in the infusion catheter and then infuse the liquid medicine. The method generally adopted is that after a bottle stopper puncture outfit is punctured into the infusion bottle stopper, a dropping funnel is inverted or extruded to enable the liquid medicine to enter the dropping funnel, and after about half of the liquid is filled into the dropping funnel, the dropping funnel is quickly restored to a normal use state, even if so, bubbles are often adsorbed on the tube wall, and medical personnel need to pinch the bubbles with fingers, so the operation method is complicated, and great inconvenience is brought to the medical personnel.
