Abstract
The utility model discloses an improvement type venous transfusion needle, including protection tube and venous transfusion needle, near bottom of protection tube is equipped with the opening, the venous transfusion needle is arranged in inside the protection tube, the butterfly wing b of venous transfusion needle arranges the protection tube outer end in through the opening, the protection tube leans on venous transfusion needle syringe needle end to be equipped with and seals, it is equipped with the closed opening of cross to seal the center, it is so not only with low costs, and clinical practical in -process, need not to change medical personnel's operation custom, the intravenous injection finishes and pulls out behind the needle, can guarantee that the syringe needle does not expose, avoid unexpected thorn to injure cross infection, safe intravenous injection has been guaranteed.
Description
Technical field
This utility model relates to a kind of venoclysis needle, particularly a kind of modified form venoclysis needle.
Background technology
Existing venoclysis needle is generally made up of piercing needle, the needle handle being arranged on piercing needle root and the anti-acupuncture sleeve pipe that is set in piercing needle outside; during use; the anti-acupuncture sleeve pipe of piercing needle outside generally takes off and loses by medical worker; after transfusion completes; piercing needle will lose the protection of anti-acupuncture sleeve pipe, and then very easily stabs medical worker.The annual whole world has nearly 1,000,000 syringe needles accident of stabbing to occur according to statistics, being in the great majority wherein because of venous transfusion needlestick injury.Shortcoming is complex structure, and manufacturing cost is high.As everyone knows, venoclysis needle belongs to disposable product, therefore for reaching transfusion needle Antipricking object, the too high improvement of complexity is carried out to its structure, must increase production and the use cost of transfusion needle, the safe intravenous infusion needle of prior art is unfavorable for popularization and the use of himself thus.Show according to investigations, the transfusion bag after transfusion and infusion bottle be all recycling to economize on resources, if return slotting infusion needle very easily cause exogenous infection, while increasing painful and medical expense to patient, too increase the professional risk of medical worker.
Utility model content
It is low that the technical problems to be solved in the utility model is to provide a kind of cost, again the modified form transfusion needle of convenient operation.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of modified form venoclysis needle, comprise hollow cylindrical protecting tube and venoclysis needle, the column limit bottom end vicinity of described protecting tube is provided with longitudinal adjustment closed type open, and Opening length is slightly longer than venoclysis needle length; The opening opposite face outer wall of described protecting tube is fixedly connected with butterfly wing a; Described protecting tube diameter is slightly larger than venoclysis needle diameter; Described venoclysis needle is placed in protecting tube inside, and the butterfly wing b of venoclysis needle is placed in protecting tube outer end by opening; Described protecting tube is provided with sealing by venoclysis needle needle end; Described sealing center is provided with cross closing any opening.
Further, the butterfly wing a on described protecting tube when device folds and the butterfly wing b of venoclysis needle in same level position.
Further, described protecting tube is translucent flexible plastic material.
Further, described sealing is Memorability flexible plastic material.
Further, described protecting tube total length is not less than venoclysis needle length.
The beneficial effects of the utility model are: cost is low, and in clinical practice process, without the need to changing the operating habit of medical personnel, venoclysis is complete pull out pin after, can guarantee that syringe needle does not expose, avoid accidental puncture and cross infection, ensure that safe vein infusion.

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 and Fig. 2 shows overall structure of the present utility model; the protecting tube 1 of this modified form venoclysis needle is enclosed within outside venoclysis needle 2; the butterfly wing b3 of venoclysis needle 2 is placed in outside protecting tube by opening a4; protecting tube 1 outer wall is provided with butterfly wing a5, by mutual reverse slide butterfly wing a5 and butterfly wing b3, venoclysis needle 2 is free to slide in protecting tube 1 along opening a4.Easy to use like this, can easily be taken in protecting tube 1 after pulling out venoclysis needle 2.Opening a4 length is slightly longer than venoclysis needle 2 length, ensures that syringe needle 6 can not expose when venoclysis needle 2 folds.And protecting tube 1 is translucent flexible plastic, opening a4 can close automatically, can fix venoclysis needle 2 position, prevents venoclysis needle 2 from independently sliding because of external force, can also observe the storage situation of venoclysis needle 2 through protecting tube 1.
Fig. 3 shows protecting tube 1 and seals top view; the top of this protecting tube 1 is provided with sealing 7; cross closing any opening b8 is provided with in the middle of sealing 7; sealing 7 is again memory-type flexible plastic; syringe needle 6 not only can be allowed freely to come in and go out; after protecting tube 1 taken in by syringe needle 6, opening b8 recovers and closes, can when without any need for operation ensure that syringe needle 6 does not leak outside.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed this utility model.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
Claims (5)
