Description
Technical field
This utility model belongs to sting device technical field, improves puncture needle more particularly, to one.
Background technology
Existing puncture needle is in use, owing to sleeve pipe and nook closing member are socketed, when performing the operation, if needing infusion medicine in human body, needing to extract the nook closing member being socketed in sleeve pipe out, extract nook closing member out and be inconvenient to operate on the one hand, another is conveniently also easy to cause danger, the operation of doctor is required higher, also has the risk that there is cross-contamination simultaneously.
Therefore, for disadvantages described above, it is badly in need of one and facilitates fluid injection to operate, the device preventing cross-contamination from producing and easy to spread and use can be protected in fluid injection simultaneously.
Utility model content
This utility model is for the deficiency of technology in current sting device, it is provided that a kind of improvement puncture needle.
The convenient infusion of drug carrying out necessity in piercing process of improvement puncture needle that this utility model provides, simultaneously, moreover it is possible to prevent medicine-pouring port to be subject to cross infection, simple to operate, it is easy to accomplish promotion and application.
This utility model reaches above-mentioned technical purpose by the following technical programs:
This utility model provides a kind of improvement puncture needle, and including nook closing member and sleeve pipe, described casing pipe sleeve is contained in outside nook closing member, and described sleeve pipe arranges liquid injection port and opening and closing device, and described liquid injection port is used for providing reservoir channel, and described opening and closing device makes liquid injection port from pollution.
By arranging liquid injection port, nook closing member can carry out the simple to operate of transfusion work, doctor or nurse while being operated, and without repeatedly extracting out or inserting nook closing member, safety increases.
Preferably, described opening and closing device includes activity box and chute, and described activity box realizes opening and closing by the movement on chute. Activity box moves on chute, it is achieved the opening and closing of liquid injection port, and this operation is very simple, and is easily achieved.
Preferably, described opening and closing device includes fill cap, and described fill cap one end is rotationally connected with on sleeve pipe by Hinge, and the described fill cap other end realizes opening and closing by buckling device. Similar with arranging of above-mentioned activity box and chute, this operation and arrange all very simple.
Preferably, described buckling device is protruding and with male cooperation through hole, and described projection is arranged on fill cap, and described through hole is arranged on sleeve pipe.
Preferably, described projection is square, rectangle or circle.
Preferably, described fill cap includes extension, and described extension is provided with contact surface, and described contact surface is curved.By arranging extension on fill cap, and the contact surface of arc is set, when carrying out operation by human hand, relies on the contact force driven opening/closing fill cap of hand and arc contact surface, further enhance the effect of simple operations.
It is highly preferred that described contact surface arranges burr.
Compared with prior art, this utility model has the following advantages and beneficial effect:
The convenient infusion of drug carrying out necessity in piercing process of improvement puncture needle that this utility model provides, simultaneously, moreover it is possible to prevent medicine-pouring port to be subject to cross infection, simple to operate, it is easy to accomplish promotion and application.
