The utility model discloses not only having very high security, making medical personnel not have the potential safety hazard when using, its simple structure is practical in addition, and low cost has the utilization to promote widely and use very much.
Description
Technical field
The utility model relates to medical apparatus and instruments, clothing arts, more particularly a kind of syringe with needle guard mechanisms.
Background technology
A kind of common medical instruments of syringe, it is for extracting and injecting various medicinal liquid or blood, but the syringe needle on syringe has very large potential safety hazard and infected risk to user when in use, a lot of medical personnel are often pricked by how sharp syringe needle in use, abnormally dangerous.At present, medical syringe is divided into ordinary syringe, self-destruction syringe and safety injector, safety injector utilizes push rod that the needle head body of syringe is retracted and inside contracts in injection body, but at safety injector not only complex structure, cost compare is high, price comparison is expensive, and can produce certain sense of discomfort to patient, does not utilize and promotes and use.
Utility model content
It is a kind of syringe with needle guard mechanisms disclosed in this utility model; its main purpose is to overcome prior art above shortcomings and shortcoming; a kind of syringe is provided; it not only has very high safety; medical personnel are made to there is not potential safety hazard when in use; and its is simple and practical, with low cost, the promotion and application widely of highly beneficial use.
The technical solution adopted in the utility model is as follows:
A kind of syringe with needle guard mechanisms, comprise syringe, push rod, piston and syringe needle, described push rod cooperation is installed in described syringe, described piston is equipped with the top end at described push rod, described syringe needle stretches out, form one and extend needle tubing, this prolongation needle tubing is arranged with one to come along this extension pin length of tube direction, returns the pipe box body slided, and the outermost end of this prolongation needle tubing is provided with one to match with injection needle the connecting portion arranged; The both sides of described prolongation needle tubing are respectively equipped with a dragging track, and described pipe box body cooperation is slidably arranged on described two dragging tracks.
Further, the bottommost of described prolongation needle tubing is provided with a clamping raised line, and described pipe box body is movable to be fixed on clamping raised line.
Further, the lateral wall of described dragging track is also provided with friction texture, this friction texture is used for holding of user and takes use.
Further, described prolongation needle tubing is also provided with a fixing salient point protruding upward, described pipe box body is provided with one and matches with described fixing salient point the card interface that card establishes.
Further, when described pipe box body slides into outermost end, this card interface and the suitable clamping of described fixing salient point are arranged.
Further, the upper surface of described pipe box body is also provided with the bar shaped burr for push-and-pull.
By above-mentioned known to description of the present utility model, compared to the prior art, the utility model has the advantage of:
This utility model extends needle tubing and the pipe box body arranged that matches with it by arranging, can medical personnel be effectively protected not stabbed by syringe needle when in use, avoid infected risk, the safety of protection medical personnel, this utility model when in use, can first by pipe box body slide downward, cover cap lives whole syringe needle, when it is desired to be used, press card interface and fixing salient point, then by pipe box body upward sliding, and be fastened on clamping raised line, re-use syringe needle to operate, after having operated, again this pipe box body is set on described prolongation needle tubing again, syringe needle is made to be subject to cover cap protection all the time, medical worker is avoided to be stabbed by it.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Structural representation when Fig. 2 is this utility model use.
Detailed description of the invention
Illustrate with reference to the accompanying drawings and detailed description of the invention of the present utility model is described further.
As shown in Figures 1 and 2; a kind of syringe with needle guard mechanisms; comprise syringe 1, push rod 2, piston 3 and syringe needle 4; described push rod 2 cooperation is installed in described syringe 1; described piston 3 is equipped with the top end at described push rod 2; described syringe needle 4 stretches out; form one and extend needle tubing 5; this prolongation needle tubing 5 is arranged with one can carry out, return slip pipe box body 6 along this extension pin length of tube direction; and the outermost end of this prolongation needle tubing 5 is provided with one to match with injection needle the connecting portion 7 arranged, injection needle can directly be socketed on this connecting portion 7.The both sides of described prolongation needle tubing 5 are respectively equipped with a dragging track 51, and described pipe box body 6 cooperation is slidably arranged on described two dragging tracks 51.
As shown in Figures 1 and 2, the bottommost of described prolongation needle tubing 5 is provided with a clamping raised line 52, described pipe box body 6 is movable to be fixed on clamping raised line 52, the lateral wall of described dragging track 51 is also provided with friction texture (due to visual angle reason, not shown in FIG.), this friction texture is used for holding of user and takes use.Described prolongation needle tubing 5 is also provided with a fixing salient point 53 protruding upward, described pipe box body 6 is provided with one and matches with described fixing salient point 53 card interface 61 that card establishes, when pipe box body 6 slides into outermost end, this card interface 61 is arranged with the suitable clamping of described fixing salient point 53.The upper surface of described pipe box body 6 is also provided with the bar shaped burr 62 for push-and-pull, and push-and-pull easy to use uses this pipe box body 6.
Using method of the present utility model, when deployed, this pipe box body 6 is upwards pushed away and establishes, its activity is made to be fixed on the clamping raised line 52 of described prolongation needle tubing 5, and expose described connecting portion 7, then injection needle and this connecting portion 7 are socket-connected and arrange, carry out extracting or injecting fluid use, after being used to complete, by the sliding downwards of this pipe box body 6, it is made to depart from this clamping raised line 52, and slide into outermost end, card interface 61 then on described pipe box body 6 coordinates the fixing salient point 53 be connected on described prolongation needle tubing 5, and injection needle is now lived by described pipe box body 6 cover cap.
