Abstract
The utility model belongs to the field of medical instruments, and particularly relates to an injector, comprising a needle tube and a needle; a needle mounting seat is arranged at the front end of the needle tube; and the needle and the needle mounting seat are connected in a clamping mode. When the injector disclosed by the utility model is used for injecting viscous medicine, the needle is not easily separated from the needle tube and is convenient to use.
Description
Technical field
This utility model belongs to medical instruments field, relates in particular to a kind of syringe.
Background technology
In medical instruments field, syringe is widely used, and syringe relies on syringe needle with contacting of patient the medicine of syringe inner chamber to be inputted in the patient body.Yet for injection relatively during the medicine of thickness, need in addition larger, permanent thrust to promote push rod drug conveying is arrived in the patient body, syringe needle comes off from syringe easily like this, and it is very inconvenient to use.
The utility model content
The purpose of this utility model is to provide a kind of syringe, to address the above problem.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of syringe, comprises syringe and syringe needle; The front end of described syringe is provided with the syringe needle mount pad; Described syringe needle is connected with described syringe needle mount pad draw-in groove.
Compared with prior art, the advantage of this utility model embodiment is: this utility model is by arranging the syringe needle mount pad at syringe, the syringe needle mount pad is connected by draw-in groove and syringe needle, when the medicine of injection thickness, in addition larger, permanent thrust promotes push rod, syringe needle is difficult for coming off from syringe, and is easy to use.
Description of drawings
Fig. 1 is the structural representation of syringe of the present utility model;
Fig. 2 is the partial sectional view of syringe of the present utility model.
The specific embodiment
Also by reference to the accompanying drawings this utility model is described in further detail below by specific embodiment.
As depicted in figs. 1 and 2, this utility model comprises syringe 1 and syringe needle 2; The front end of described syringe 1 is provided with syringe needle mount pad 3; Described syringe needle 2 and described syringe needle mount pad 3 clampings, syringe needle 2 be fixed with syringe 1 on, can prevent that in injection process syringe needle 2 from coming off from syringe 1.
The inner chamber of described syringe needle 2 is provided with the first groove 2a; Be provided with the first raised line 3a on the described syringe needle mount pad 3; Described the first raised line 3a cooperates with the first groove 2a, cooperates by the first raised line 3a on the syringe needle mount pad 3 and the first groove 2a on the syringe needle 2 syringe needle 2 is fixed on the syringe needle mount pad 3.
Described the first raised line is two, and described the first groove is two simultaneously.Certainly, the number of described the first raised line and described the first groove can be other any number.
Certainly the mode of clamping can be another kind of structure, and the inner chamber of described syringe needle 2 is provided with the second raised line; Be provided with the second groove on the described syringe needle mount pad 3; Described the second groove cooperates with the second raised line, by the second raised line on the syringe needle 2 and the second groove fit on the syringe needle mount pad 3 syringe needle 2 is fixed on the syringe needle mount pad 3.
Described the second raised line is two, and described the second groove is two simultaneously.Certainly, the number of described the second raised line and described the second groove can be other any number.
This utility model also comprises push rod 5; The rear end of described syringe 1 is provided with the propelling cover 6 with female thread; Described push rod 5 is provided with external screw thread; The female thread of described propelling cover 6 cooperates with the external screw thread of described push rod 5; By screw thread is set, only need impose less power rotating push-rod 5, the push rod 5 that then rotates is with respect to advancing cover 6 to move along the axis of push rod 5.
This utility model also comprises the piston 4 that is connected with described push rod 5; The internal chamber wall of described syringe 1 is provided with female thread, and described piston 4 is provided with the external screw thread that matches with the internal chamber wall female thread of described syringe 1; By the internal chamber wall threaded engagement of piston 4 with syringe 1, being conducive to piston 4 can do axially-movable synchronously with push rod 5.
The end face of described piston is tapered; The end face of the inner chamber of described syringe has the cone tank that cooperates with piston-top surface, has improved the sealing of piston 4.
The rear end of described push rod 5 is provided with rotating part 7, makes things convenient for the rotation of push rod 5, and described rotating part 7 is hollow structure, and the internal chamber wall of described rotating part 7 is provided with the female thread that cooperates with the external screw thread of described push rod 5, and rotating part 7 is stabilized on the push rod 5.
Further, described syringe needle 2 can also be the non-toxic medical plastic flexible pipe, and described syringe 1 is special-purpose PP plastic material, and described piston 4 is special-purpose PE material, and the PE material has under the room temperature water insoluble, the characteristics that resistance to acids and bases is strong.
The above is preferred embodiment of the present utility model only, is not limited to this utility model, and for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
