Description

Needleless transfusion system and transfusion bag valve

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a needleless transfusion system and infusion bag valve.

Background

What present transfusion system top was used is the needle point, it is rubber or with the supporting tang of needle point to connect the infusion bag bottom, can alternate repeatedly to the rubber bottom, but the phenomenon of leaking appears easily, to the tang, only allow to alternate once, need promptly change the fluid infusion sometimes in the infusion process, can appear the last bag who has not yet infused the end condition, just so be difficult to not deposit the liquid that does not infuse the end, and pull out when all being easy by the infant activity and cause unplanned tube drawing, and still need subtract the transfusion system needle point when infusing the end processing rubbish, both increased sharp ware treatment cost, increase nurse's work load again, we propose needleless transfusion system and infusion bag valve for this reason.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a needleless infusion device and an infusion bag valve.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the needleless infusion device and the infusion bag valve comprise an infusion device, wherein a connecting device is arranged at the lower part of the infusion device, the connecting device comprises two groups of puncture shells, the cross sections of the puncture shells are semicircular, a puncture catheter is clamped in the puncture shells, and threads are carved on the upper parts of the inner walls of the puncture shells.

Preferably, one side of the vertical section of the puncture shell is uniformly provided with a plurality of groups of connecting pins, and the other side of the vertical section of the puncture shell is uniformly provided with a plurality of pin holes matched with the connecting pins.

Preferably, a plurality of groups of side holes are formed in the top end of the puncture catheter, the top of the puncture catheter is sharp, and the top of the puncture catheter is punctured into the infusion device.

Preferably, the infusion device comprises an infusion bag and a syringe.

Preferably, a needle-free closed joint type opening is installed at the opening at the tail end of the infusion bag, and the output ends of the infusion bag and the injector are in screw shapes matched with the internal threads of the puncture shell.

The utility model has the advantages that:

(1) through the screw-shaped arrangement of the output ends of the infusion bag and the injector, the device is tightly connected, the problem of tube detachment is solved, the workload of nurses is reduced, and the treatment cost of sharp instruments can be reduced;

(2) through the setting of puncture shell and puncture pipe for device convenient to detach and repeated connection avoid the appearance of the condition of the pollution of leaking.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-4, a needleless infusion device and an infusion bag valve comprise an infusion device, wherein the infusion device comprises an infusion bag 3 and an injector 6, a connecting device is arranged at the lower part of the infusion device, the connecting device comprises two groups of puncture shells 1, the cross sections of the puncture shells 1 are semicircular, a puncture catheter 2 is clamped in the puncture shells 1, threads are carved on the upper part of the inner wall of the puncture shells 1, and in the using process, the output end of the infusion device is continuously screwed downwards, so that the puncture catheter 2 penetrates into the infusion device.

Furthermore, one side of the vertical section of the puncture shell 1 is uniformly provided with a plurality of groups of connecting pins 5, and the other side of the vertical section of the puncture shell is uniformly provided with a plurality of pin holes matched with the connecting pins 5, so that the puncture shell 1 can be well detached and installed in the using process, the puncture catheter 2 is convenient to replace, and the puncture catheter is convenient to disinfect and use.

Furthermore, a plurality of groups of side holes 4 are formed in the top end of the puncture catheter 2, the top of the puncture catheter 2 is sharp, the top of the puncture catheter 2 is punctured into the infusion device, and the introduced liquid can well enter the inner knife of the puncture catheter 2 through the side holes 4 for transmission.

Further, needleless close fitting formula opening is installed to infusion bag 3's end opening part, and infusion bag 3 and syringe 6's output are the screw mouth form with 1 inside screw thread adaptation of puncture shell, can reach better and connect inseparable effect in the in-process of using, avoid the emergence of improper tube drawing, and can reduce nurse's work load.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
