Abstract
The utility model discloses a kind of syringe, comprise syringe needle, syringe, push rod and be arranged on the piston of push rod one end, syringe needle comprises syringe needle tube and Connection Block, Connection Block comprises the needle tubing seat, the profile that are fixedly connected sequentially and is the mount pad of hex nut shape and is provided with externally threaded connection base, the syringe needle junction inwall of described syringe is provided with and the female thread being connected base and adapting, and the leading section of described syringe is also provided with annular flange flange.The beneficial effects of the utility model are: structure is simple, is threaded connection and the mount pad on syringe needle is designed to hex nut shape between syringe needle and needle tubing, both stable connections and easy accessibility, can effectively increase work efficiency.When syringe is extracted out from air-tight bottle, finger can be fastened the annular flange flange being arranged on syringe needle tube leading section, conveniently syringe needle be transferred to.Annular flange flange can be designed to emery wheel further, also syringe can be used as ampoule opener, easy to use and can increase work efficiency.
Description
Technical field
This utility model relates to medical apparatus technical field, especially a kind of syringe.
Background technology
The conventional syringe of current Clinical practice, generally comprise syringe needle, syringe, push rod and be arranged on the piston of push rod one end, the connected mode of its syringe needle and syringe be injection needle is inserted in the breast injecting body front end convex on, undertaken making up a prescription by the mode of pull syringe and be patient injection.Though existing syringe can meet fundamental need, also exist following not enough: 1, syringe needle is connected with syringe very insecure, when extracting needle guard, easily taking out of also suitable for syringe needle, using inconvenience.And it is not syringe needle Connection Block smoother is tiny, easy to operate during replacing.2, the general smoother of syringe, after air-tight bottle extracts medicine, it is more difficult to extract, and too firmly easily makes again syringe needle come off or prick in one's hands, uses inconvenience.3, function is comparatively single, when using syringe to extract medicine in ampoule bottle, needs, with emery wheel scribing ampoule bottle cervical region, to waste time and energy toward contact, but also sometimes because can not find emery wheel soft white hands without plan.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned prior art, provides that a kind of structure is simple, syringe needle stable connection and syringe easy to use.
To achieve these goals, the technical solution adopted in the utility model is: a kind of syringe, comprise syringe needle, syringe, push rod and be arranged on the piston of push rod one end, it is characterized in that: described syringe needle comprises syringe needle tube and Connection Block, Connection Block comprises the needle tubing seat, the profile that are fixedly connected sequentially and is the mount pad of hex nut shape and is provided with externally threaded connection base, the syringe needle junction inwall of described syringe is provided with and the female thread being connected base and adapting, and the leading section of described syringe is also provided with annular flange flange.
Further, described needle tubing seat, mount pad and connection base are one-body molded, and connection base is also set with sealing ring.
Further, described annular flange flange is open the emery wheel of ampoule bottle.
The beneficial effects of the utility model are: structure is simple, is threaded connection and the mount pad on syringe needle is designed to hex nut shape between syringe needle and needle tubing, both stable connections and easy accessibility, can effectively increase work efficiency.When syringe is extracted out from air-tight bottle, finger can be fastened the annular flange flange being arranged on syringe needle tube leading section, conveniently syringe needle be transferred to.
Further, by annular flange flange is designed to emery wheel, also syringe can be used as ampoule opener, directly open after ampoule bottle with syringe and extract medicine, easy to use and can increase work efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of syringe needle in this utility model.
Detailed description of the invention
As shown in Figure 1, 2, a kind of syringe of this utility model, comprises syringe needle 1, syringe 2, push rod 3 and is arranged on the piston 4 of push rod 3 one end.Wherein, syringe needle 1 comprises syringe needle tube 11 and Connection Block 12.Connection Block 12 comprises the needle tubing seat 121, the profile that are fixedly connected sequentially and is the mount pad 122 of hex nut shape and is provided with externally threaded connection base 123.The syringe needle junction inwall of syringe 2 is provided with and the female thread being connected base 123 and adapting, the leading section of syringe 2 is also provided with annular flange flange 5, so designs, when syringe is extracted out from air-tight bottle, finger can be fastened annular flange flange 5 power-assisted, conveniently extract syringe needle.
In the present embodiment, above-mentioned needle tubing seat 121, mount pad 122, with to be connected base 123 one-body molded, connection base 123 are also set with sealing ring 124, to strengthen the sealing property of junction.In order to make the functional diversities of syringe, above-mentioned annular flange flange 5 can be designed for the emery wheel opening ampoule bottle.
Finally should be noted that; above content is only in order to illustrate the technical solution of the utility model; but not the restriction to this utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or equivalently to replace, does not all depart from essence and the scope of technical solutions of the utility model.
