Abstract
The invention relates to the technical field of syringe product design, in particular to an easy-to-destroy syringe which comprises a needle, a cylinder and a needle bar matched with the cylinder. The front end of the needle bar is provided with a rubber piston matched with the inner wall of the cylinder, a rubber ring protruding rib is fixedly arranged on the inner ring surface at the open position of a cylinder opening, the needle comprises a stainless steel injection head and a medical plastic connecting tube which are fixedly connected, the medical plastic connecting tube is of a uniform-diameter cylindrical cavity structure, the inner wall of the medical plastic connecting tube is fixedly connected with a rubber layer, an outlet is arranged at the edge of the front end of the cylinder, the outer diameter of the outlet is in a gradual diameter decreasing type structure, and the inner diameter of the medical plastic connecting tube is between the outer diameters of the two ends of the outlet. The easy-to-destroy syringe is simple in structure, convenient, practical and suitable for popularization and application.
Description
Technical field
The present invention relates to syringe articles for use design field, particularly a kind of easy destruction type syringe.
Background technology
Syringe is the common articles for use of field of medicaments, it is mainly comprised of syringe needle, syringe and shank, in conventional syringe, syringe lacks good restriction to the shank being arranged on wherein, if shank does not slightly notice in the process toward post-tensioning just that easily slippage out from syringe, easily cause malpractice, in addition, the structure of syringe needle and syringe junction arranges and easily makes the more difficult destruction of syringe used, easily to lawless person, builds illegal leak.Therefore, studying a kind of simple in structure, convenient and practical easy destruction type syringe is the current problem that will study.
Summary of the invention
The technical problem to be solved in the present invention is: for overcoming the problem of above-mentioned existence, provide a kind of simple in structure, convenient and practical easy destruction type syringe.
The technical solution adopted for the present invention to solve the technical problems is: a kind of easy destruction type syringe, this syringe comprises syringe needle, syringe and the shank matching with syringe, described shank front end is provided with the rubber piston suitable with syringe inwall, and rubber ring fin is fixedly installed on the inner ring face of opening part of syringe nozzle; Described syringe needle comprises rustless steel injection head and the medical plastic connection tube being fixedly connected with, and medical plastic connection tube is the uniform cylindrical cavity structure of diameter, and medical plastic connection tube inwall is fixedly connected with rubber layer; The front edge of described syringe is provided with outlet, and outlet external diameter is gradually small-scale structure of diameter, and the interior diameter of described medical plastic connection tube is between the external diameter at outlet two ends.
Further, described rubber piston front end is planarized structure.
Further, described rustless steel injection head front end is inclined structure.
Further, described shank end is vertically installed with push rod.
Beneficial effect: the structure of easy destruction type syringe of the present invention is comparatively simple, convenient and practical, in technical scheme of the present invention, the front edge of syringe is provided with to outlet, can be conducive to this syringe and use the destruction that fractures later, medical plastic connection tube inwall is fixedly connected with the setting of rubber layer, can make medical plastic connection tube comparatively tight with outlet combination, also be beneficial to the destruction of later stage syringe, the setting of rubber ring fin, can effectively prevent shank from syringe slippage out, suitable applying.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
1. syringes in figure, 11. rubber ring fins, 12. outlets, 2. shank, 21. rubber pistons, 22. push rods, 31. rustless steel injection heads, 32. medical plastic connection tubes.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only show the formation relevant with the present invention.
A kind of easy destruction type syringe as shown in Figure 1, this syringe comprises syringe needle, syringe 1 and the shank 2 matching with syringe 1, described shank 2 ends are vertically installed with push rod 22, shank 2 front ends are provided with the rubber piston 21 suitable with syringe 1 inwall, the inner ring face of the nozzle of syringe 1 is provided with a rubber ring fin 11, rubber ring fin 11 is fixedly installed on the inner ring face of opening part of syringe 1 nozzle, has the aperture matching with shank 2 diameters in the middle of rubber ring fin 11; Described syringe needle comprises rustless steel injection head 31 and the medical plastic connection tube 32 being fixedly connected with, rustless steel injection head 31 front ends are inclined structure, medical plastic connection tube 32 is the uniform cylindrical cavity structure of diameter, and medical plastic connection tube 32 inwalls are fixedly connected with rubber layer; The front edge of described syringe 1 is provided with outlet 12, exporting 12 external diameters is gradually small-scale structure of diameter, the interior diameter of described medical plastic connection tube 32 is between the external diameter at outlet two ends, described rubber layer can make medical plastic connection tube 32 and outlet 12 tight clampings, is also convenient to the later stage by the destruction herein of this syringe.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content in description, must determine its technical scope according to claim scope.
