Abstract
The utility model discloses a syringe which comprises a needle tube, a piston handle arranged in the needle tube, a needle bolt that is sheathed and connected with the top of the needle tube, a needle point fixedly connected on the needle bolt, and a needle protecting cap arranged outside the needle bolt and the needle point, wherein the outer wall of the needle bolt and the inner wall of the needle protecting cap are respectively provided with thread, and the thread of the needle bolt is matched with that of the needle protecting cap. According to the syringe, the needle protecting cap can be stably and rapidly taken off, so that a medical worker is effectively protected from being hurt by the needle point when pulling out the needle protecting cap in an overexerting way; and furthermore, the abrasion for the needle point caused by the inner wall of the needle protecting cap can be avoided, and the working efficiency is improved.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of syringe.
Background technology
Syringe is a kind of medical instruments commonly used, is mainly used in liquid medicine injection or drawing liquid, ordinary syringe protect the pin medicated cap and pintle is the connected mode of interference fit; Medical personnel are in pulling up the process of protecting the pin medicated cap; Overexerting to receive the injury of needle point because of the inertia retraction of arm, in addition, because needle point is longer; Protected the inner wall abrasion of pin medicated cap easily and influenced result of use, even the needle point that can fracture.
The utility model content
The technical problem that this utility model will solve provides a kind of syringe; Can steadily will protect the pin medicated cap quickly and remove, prevent effectively that medical personnel from pulling out when protecting the pin medicated cap because of overexerting to receive the needle point injury, in addition; Avoided protecting of the wearing and tearing of pin medicated cap inwall, improved work efficiency needle point.
To achieve these goals; The technical scheme that this utility model is taked is: a kind of syringe; Comprise needle tubing, be arranged on the inner piston handle of needle tubing, be socketed in the vertical pintle of needle tubing, be fixedly connected on the needle point on the pintle and be arranged on pintle and needle point is outside protects the pin medicated cap, the outer wall of said pintle and the said inwall that protects the pin medicated cap are provided with the screw thread of mutual coupling.
As a kind of optimal technical scheme of this utility model, said screw thread is one to three circle.
As a kind of optimal technical scheme of this utility model, said screw thread is two circles.
As a kind of optimal technical scheme of this utility model, the said outer wall that protects the pin medicated cap is horizontally arranged with anti-skidding stricture of vagina.
Adopt the beneficial effect that technique scheme produced to be: the protecting to adopt between pin medicated cap and the pintle of this utility model is threaded; Can steadily will protect the pin medicated cap quickly removes; Preventing effectively that medical personnel from pulling out when protecting the pin medicated cap because of overexerting receives the needle point injury, in addition, has avoided protecting the wearing and tearing of pin medicated cap inwall to needle point; Improved work efficiency, anti-skidding stricture of vagina can play anti-skidding effect.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Among the figure: 1, needle tubing 2, piston handle 3, pintle 4, needle point 5, screw thread 6, anti-skidding stricture of vagina 7, protect the pin medicated cap.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done further detailed explanation.
Referring to accompanying drawing; Comprise needle tubing 1 in the structure of a specific embodiment of this utility model, be arranged on the inner piston handle 2 of needle tubing 1, be socketed in the vertical pintle of needle tubing 13, be fixedly connected on the needle point 4 on the pintle 3 and be arranged on pintle 3 and needle point 4 is outside protects pin medicated cap 7; The outer wall of pintle 3 is provided with the two circles screw thread 5 of coupling each other with the inwall that protects pin medicated cap 7, and the outer wall that protects pin medicated cap 7 is horizontally arranged with anti-skidding stricture of vagina 6.
Protecting of this utility model adopts screw thread 5 to connect between pin medicated cap 7 and the pintle 3; During use, protect pin medicated cap 7 through rotation and can steadily will protect pin medicated cap 7 quickly and remove, prevent effectively that medical personnel from pulling out when protecting pin medicated cap 7 to receive needle point 4 injuries because of overexerting; In addition; Avoided protecting the wearing and tearing of pin medicated cap 7 inwalls to needle point 4, improved work efficiency, anti-skidding stricture of vagina 6 can play anti-skidding effect.
Foregoing description only proposes as the enforceable technical scheme of this utility model, not as the single restrictive condition to its technical scheme itself.
