Technical Field

The invention relates to the field of medical instruments, in particular to a dripping type downward-penetrating puncture outfit and an infusion apparatus matched with the same.

Background

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 puncture outfit, an air inlet pipe air filter and a transfusion container (a transfusion bottle or a transfusion bag) connecting structure. In the case of a conventional puncture device, which is generally of the top-piercing type, in use, the opening of the infusion container is downward, and the tip of the puncture device is upward to pierce the opening cover of the infusion container. The puncture outfit has a hole at the tip and a hollow tubular structure in the body. The structure only considers the convenience of the puncture outfit entering the transfusion bag or the transfusion bottle at the beginning of the design.

The inventor finds in practical work that the puncture outfit of the above type has certain drawbacks: because the trompil of puncture ware is located tip region, in the infusion later stage, the liquid medicine that is less than puncture ware trompil position can be detained in sack or bottleneck position, can't get into in the transfer line, causes the waste of liquid medicine.

After measurement, about 5% of the infusion liquid medicine in a 100ml standard bag is finally retained and can not be completely dripped if a traditional puncture outfit is adopted. For example, about 5ml of a 100ml standard infusion solution is retained and cannot be completely dropped. In recent years, the production of large infusion solutions in China is over 100 hundred million bottles/bag throughout the year, if traditional puncture outfits are used, the total amount of the residual liquid medicine at the mouth of an infusion bag or the mouth of an infusion bottle is large, and the following problems are brought: 1. the human body is lack of medicine; 2. waste of medical resources and funds is caused; 3. the residual liquid medicine, if discarded, can cause serious environmental pollution, and if further processed, will undoubtedly increase the cost. Therefore, the above problems need to be solved.

In view of the above problems, the inventors have previously proposed a solution to the above problem by changing the position of the puncture head opening. Meanwhile, the inventor also finds another completely different idea to solve the problem, so that the position of the liquid outlet of the puncture head can be not limited.

Disclosure of Invention

The invention aims to provide a clean dripping type downward-penetrating puncture outfit and an infusion apparatus matched with the same, which can solve the problem of residual liquid medicine at a liquid outlet of an infusion container when the infusion process is finished.

In order to solve the problems in the prior art, the invention provides a clean-dropping type downward-penetrating puncture outfit, which is provided with a puncture head at one end and an opening at the puncture head.

Preferably, a switch is arranged on the connecting pipe.
