At present, the known medical disposable infusion apparatus is mainly used for intravenous infusion, and is a common disposable consumable for establishing a channel between a vein and liquid medicine through aseptic treatment. Generally comprises a vein needle, a protective cap, a transfusion hose, a liquid medicine filter, a flow rate regulator, a drip cup, a bottle stopper puncture outfit, an air inlet pipe air filter and a transfusion bottle or transfusion bag connecting structure. The principle of medical infusion is to utilize: mainly adopts the principle that the infusion liquid freely falls from a high place under the action of gravity (earth gravity) and auxiliary pressure (atmospheric pressure) to finish the process of medicine and infusion for a human body. Because the pharmaceutical process of the infusion medicine that directly is used for human body to administrate is complicated with higher costs, for a long time, the not enough in traditional transfusion system structure and design, cause in the later stage of the infusion process of dripping, can't give the medicine to the human body of receiving the medicine completely, remain in the transfusion system liquid medicine and directly abandoned, be the phenomenon that exists widely for a long time in the medical system, it directly brings the problem to be: 1. the human body is lack of medicine; 2. waste of medical resources and funds is caused; 3. the method increases the invisible burden of pharmaceutical enterprises, medical enterprises and common people, and generates huge accumulated quantity of waste, so that the problem is ignored for a long time.
In view of the above problems, the applicant has made an improvement, and proposed in ZL 201611050138.8 (granted), a bag-in-infusion/drip-clean type medical infusion apparatus for an infusion bottle or an infusion bag, which is obtained by implanting a plastic bag or a spherical bag having six needle holes uniformly distributed on the surface thereof in a conventional infusion bottle or infusion bag. The infusion bottle or the infusion bag is injected with the base liquid during production, meanwhile, the PVC plastic bag or the spherical bag is naturally and auxiliarily filled with the base liquid, when the infusion bottle or the infusion bag is used for medical treatment, before infusion dripping is finished, the infusion bottle or the infusion bag is emptied, wherein the base liquid of the PVC plastic bag or the spherical bag seeps and drips into the infusion bottle or the infusion bag and the infusion hose from the reserved needle hole under the action of negative pressure, the seepage amount of the base liquid is suitable for the dripping amount of the infusion liquid, the liquid medicine in the infusion system and the infusion hose is completely infused and dripped and washed by the base liquid in the dripping process under the action of continuous dripping, and finally the base liquid which is subsequent to the PVC plastic bag or the spherical bag is remained in the. The scheme can solve the problem of residual liquid medicine in the infusion apparatus system, but simultaneously has the following defects: because the utricule is located bottleneck department, under some circumstances, for example when circular infusion bottle adopted circular sacculus, probably caused the absorption in bottleneck department, lead to liquid outflow to be obstructed in the bottle and cause the interior liquid of bag to flow out in advance, perhaps because the position is improper, the pinhole does not be located the utricule bottom, and later stage bag interior liquid can not flow the fluid infusion smoothly. Therefore, further improvements are still needed.
