Abstract
The utility model discloses a kind of needle guard mechanisms, and including the pinhead sleeve being coated on outside syringe needle and the outer tube sleeve for pulling pinhead sleeve, the flexible boot that the pinhead sleeve is open rearward end, front end is closed, the outer tube sleeve is the hard set of both ends open；The outer tube sleeve is sleeved on outside flexible boot and the front end of flexible boot is connected with the front end of outer tube sleeve, and the rear end inner wall of the outer tube sleeve is equipped with and the mutually fixed buckling body in needle plastic portion；It is connected by needle guard mechanisms with syringe needle, outer tube sleeve pull-up fixation can be completely exposed syringe needle during use, pinhead sleeve and outer tube sleeve are resetted after being finished can effectively prevent pricking wound, and be avoided that syringe needle pollutes.Simple in structure, using effect is good.
Description
Technical field
The utility model belongs to medicine and hygiene fields, and in particular to a kind of needle guard mechanisms.
Background technology
Pricking wound occurs more in clinical position, and many medical personnels are due to the needlestick injuries being used by the patient
Result in infection.Existing syringe needle only there are one the protection of separated needle cap, is primarily present problems with：(1) needle cap exists
It is not easy to put on as returned set with one hand when returning set, and easy contaminated pinhead；(2) because needle cap bore is smaller, set is with the hands returned
Shi Rongyi stabs hand.
The content of the invention
In view of this, the purpose of this utility model is to provide a kind of needle guard mechanisms, make it that can effectively prevent
Syringe needle secondary separation (removes syringe needle) after being finished from syringe, and is avoided that and is damaged to medical personnel.
In order to achieve the above objectives, the utility model provides following technical solution：A kind of needle guard mechanisms, including being coated on
The outer tube sleeve of pinhead sleeve and pulling pinhead sleeve outside syringe needle, the flexible boot that the pinhead sleeve is open rearward end, front end is closed are described
Outer tube sleeve is the hard set of both ends open；The outer tube sleeve is sleeved on flexible boot outer and the front end of flexible boot and the front end of outer tube sleeve
It is connected, the rear end inner wall of the outer tube sleeve is equipped with and the mutually fixed buckling body in needle plastic portion.
Further, the front end of the pinhead sleeve is equipped with easily opening.
Further, the thickness of the pinhead sleeve be 0.5~1.0mm, a length of 2~2.5cm of outer tube sleeve, diameter 0.8~
1.2cm。
The beneficial effects of the utility model are：It is connected by needle guard mechanisms with syringe needle, when use will be in outer tube sleeve
Draw fixation that can be completely exposed syringe needle, pinhead sleeve and outer tube sleeve are resetted after being finished can effectively prevent pricking wound, and be avoided that pin
Head pollution.Simple in structure, using effect is good.
Description of the drawings
In order to make the purpose of this utility model, technical solution and advantageous effect clearer, the utility model provides as follows
Attached drawing illustrates：
Fig. 1 is the structure diagram of the utility model；
The contraction state schematic diagram of Fig. 2 the utility model.
Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
As shown in the figure, the needle guard mechanisms in the utility model, including the pinhead sleeve 2 being coated on outside syringe needle 1 and pull
The outer tube sleeve 3 of pinhead sleeve, the flexible boot that the pinhead sleeve 2 is open rearward end, front end is closed, the outer tube sleeve 3 are both ends open
Hard set；The outer tube sleeve is sleeved on outside flexible boot and the front end of flexible boot is connected with the front end of outer tube sleeve, the outer tube
The rear end inner wall of set is equipped with and 4 mutually fixed buckling body 5 of needle plastic portion.
Specifically, the front end of the pinhead sleeve 2 in the present embodiment is equipped with easily opening, it is easy to syringe needle and punctures pinhead sleeve 2, outer tube sleeve
Front end is connected with 2 front end of pinhead sleeve, when outer tube sleeve is moved to 4 side of needle plastic portion pinhead sleeve 2 can be driven to move up, so as to expose
Syringe needle；Buckling body 5 on the rear end inner wall of outer tube sleeve is fixed with 4 phase of needle plastic portion, can prevent pinhead sleeve 2 from resetting.
In use, first pulling up outer tube sleeve, syringe needle punctures pinhead sleeve and exposes syringe needle；Outer tube sleeve is fixed on needle plastic
In portion, prevent pinhead sleeve 2 from resetting；After being finished, outer tube sleeve and needle plastic portion are freed, pinhead sleeve and outer tube sleeve are resetted, covered
Syringe needle.The structure not only can effectively prevent pricking wound, moreover it is possible to syringe needle be avoided to pollute.
The thickness of pinhead sleeve in the present embodiment is 0.5~1.0mm, and a length of 2~2.5cm of outer tube sleeve (is moulded with syringe needle
Expect that minister's degree is suitable), 0.8~1.2cm of diameter, outer tube sleeve front end 1/3 is connected with pinhead sleeve front end and leaves part at two ends
Gap prevents from surprisingly syringe needle being caused to puncture pinhead sleeve.
Finally illustrate, preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage
Solution, can in the form and details make it various changes, without departing from the utility model claims book institute
The scope of restriction.
