Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of syringe.
Background technology
Syringe is the medical apparatus and instruments for the subcutaneous injection medicine, because the unicity of its purposes and the visual stimulus of sharp needle, the resistance that can make the child produce trained reflex is unfavorable for the injection of medicine.
The utility model content
The purpose of this utility model is to provide a kind of syringe needle concealed syringe, mainly solve and resist the problem of injecting after the child sees syringe needle, this syringe can not seen syringe needle by syringe needle is hidden in the rubber sleeve in whole injection process, realize the smoothly purpose of injection.
The technical scheme in the invention for solving the technical problem is: the concealed syringe of syringe needle, its structure comprises cylindrical shell, syringe needle, push rod and ampoule, described inner barrel hollow, the cylindrical shell head center is provided with syringe needle, be provided with the circle rubber ring contour with syringe needle around the syringe needle, inner barrel is provided with dividing plate, and the dividing plate front portion is provided with the ampoule that can take out, the dividing plate rear portion is provided with push rod, is provided with spring between push rod and the dividing plate.
Described ampoule head can be by needle pierces, and afterbody is provided with mobilizable sealing slide block.
The beneficial effects of the utility model are: adopt the structure that rubber ring is set around syringe needle, syringe needle is hidden, syringe needle can not expose in injection process, avoids causing that the child is panic.
Description of drawings
Fig. 1 is schematic top plan view of the present utility model;
Fig. 2 is that cutaway view is looked on the left side of Fig. 1.
Among the figure: 1 needle cover, 2 rubber rings, 3 syringe needles, 4 cylindrical shells, 5 ampoulies, 6 sealing slide blocks, 7 dividing plates, 8 push rods, 9 springs, 10 tail-hoods.
The specific embodiment
As shown in Figure 1 and Figure 2.The concealed syringe of syringe needle, its structure comprises cylindrical shell 4, syringe needle 3, push rod 8 and ampoule 5, described cylindrical shell 4 inner hollow, the center of cylindrical shell 4 heads is provided with syringe needle 3, be provided with the contour rubber ring 2 of a circle and syringe needle 3 around the syringe needle 3, the inside of cylindrical shell 4 is provided with dividing plate 7, and the front portion of dividing plate 7 is provided with the ampoule 5 that can take out, the rear portion of dividing plate 7 is provided with push rod 8, is provided with spring 9 between push rod 8 and the dividing plate 7.
The head of described ampoule 5 can be pierced through by syringe needle 3, and the afterbody of ampoule 5 is provided with mobilizable sealing slide block 6.Be respectively equipped with medicated pillow lid 1 and tail-hood 10 at the two ends of cylindrical shell for the protection of syringe needle 3 and push rod 8.
During use, the ampoule 5 that medicament is housed is put in the cylindrical shell 4, the nurse moves forward with hand propelled push rod 8, and push rod 8 can head on ampoule 5 and move to the direction of syringe needle 3, until syringe needle 3 punctures the head of ampoule 5 and communicates with its inside.The process that the nurse is thrust child's skin with syringe needle 3, syringe needle 3 can be hidden by rubber ring 2, and syringe needle 3 can not expose in injection process, avoids causing that the child is panic, because rubber ring 2 has elasticity, therefore can be out of shape along with thrusting of syringe needle 3 compression.The nurse continues to promote push rod 8, and sealing slide block 6 is moved forward, and it is subcutaneous that medicinal liquid is injected into the patient, finishes injection process.
