Abstract
The invention relates to a universal needle device. The universal needle device comprises a first needle tube and a second needle tube, wherein a sleeve butt-jointed with a syringe is arranged at one end of the first needle tube, a universal tube joint is arranged between the other end of the first needle tube and one end of the second needle tube, a needle tip is arranged at the other end of the second needle tube, a sliding sleeve is arranged on the outer side of the universal tube joint, the other end of the first needle tube and one end of the second needle tube are sleeved with guiding blocks, peripheries of the guiding blocks are matched with the inner wall surface of the sliding sleeve, an axial extension part is arranged on the sliding sleeve close to one side of the needle tip and is an elastic piece, and a reset spring is arranged between the sliding sleeve and the sleeve. The universal needle device can be in the rigid connection during needle stabbing, smooth conduction of needle stabbing is guaranteed, the axial extension part is contacted with the skin and pushes the sliding sleeve to move backwards along with stabbing of the needle tubes, the universal tube joint is released, flexible connection is realized, and the needle tubes cannot be broken in flesh.
Description
Technical field
The invention belongs to Medical decontaminated apparatus, particularly a kind of universal needle apparatus.
Background technology
The needle tubing of existing syringe needle is the straight tube of rigidity, and front end is provided with needle point, and rear end is provided with the sleeve docked with syringe.Such syringe needle, when to injections such as domestic animals, easily fractures in skin and flesh.Not only affect injection, and not easily take out at the needle tubing of skin and flesh.Therefore, we need a kind of can be the needle tubing of rigidity when having an acupuncture treatment, and penetrate put in place after show as flexible syringe needle.
Summary of the invention
The object of the present invention is to provide a kind of universal needle apparatus, this universal needle apparatus can show as the connection of rigidity when having an acupuncture treatment, ensure carrying out smoothly of acupuncture treatment, and penetrating along with needle tubing, because axial extension touches skin, and move after promoting sliding sleeve, universal pipe joint is untied, realization flexibly connects, and needle tubing can not be fractureed in skin and flesh.
Technical program of the present invention lies in: a kind of universal needle apparatus, comprise the first needle tubing and the second needle tubing, described first needle tubing one end is provided with the sleeve docked with syringe, universal pipe joint is provided with between the other end of described first needle tubing and an end of the second needle tubing, the other end of described second needle tubing is provided with needle point, described universal pipe joint arranged outside has a sliding sleeve, the other end of described first needle tubing and an end of the second needle tubing are all equipped with guide pad, the peripheral part of described guide pad coordinates with sliding sleeve internal face, an axial extension is provided with on the sliding sleeve of needle point one sidepiece, described axial extension is flexure strip, back-moving spring is provided with between described sliding sleeve and sleeve.
In one embodiment, described universal pipe joint comprise be connected to the first needle tubing the other end on spherical rotary head and be connected to an end bell and spigot joint of the second needle tubing, described bell and spigot joint inner chamber coordinates with spherical rotary head, and mating surface is provided with leakproof seal circle.
The invention has the advantages that: one is this universal needle apparatus can show as rigidity connection when having an acupuncture treatment, ensure carrying out smoothly of acupuncture treatment, and penetrating along with needle tubing, because axial extension touches skin, and move after promoting sliding sleeve, universal pipe joint is untied, realizes flexibly connecting, needle tubing can not be fractureed in skin and flesh; Two is easy to use, has higher use value.
Accompanying drawing explanation
Fig. 1 is the universal needle apparatus structural representation in embodiment.
Fig. 2 is the universal needle apparatus using state schematic diagram in embodiment.
In figure: spherical rotary head 42 bell and spigot joint 71 first guide pad 72 second guide pad of the 1 first needle tubing 2 second needle tubing 3 sleeve 4 universal pipe joint 5 needle point 6 axial extension 9 back-moving spring 10 leakproof seal circle 41 of sliding sleeve 8.
Detailed description of the invention
For above-mentioned feature and advantage of the present invention can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
Please refer to Fig. 1 and Fig. 2, universal needle apparatus of the present invention, comprise the first needle tubing 1 and the second needle tubing 2, described first needle tubing 1 one end is provided with the sleeve 3 docked with syringe, universal pipe joint 4 is provided with between the other end of described first needle tubing 1 and an end of the second needle tubing 2, in the present embodiment, described universal pipe joint 4 comprises the spherical rotary head 41 on the other end being connected to the first needle tubing 1 and is connected to an end bell and spigot joint 42 of the second needle tubing 2, described bell and spigot joint inner chamber coordinates with spherical rotary head, and mating surface is provided with leakproof seal circle 10.
The other end of above-mentioned second needle tubing 2 is provided with needle point 5, described universal pipe joint 4 arranged outside has a sliding sleeve 6, the other end of described first needle tubing 1 and the one end portion of the second needle tubing 2 are not equipped with the first guide pad 71 and the second guide pad 72, the peripheral part of described guide pad 7 coordinates with sliding sleeve 6 internal face, an axial extension 8 is provided with on the sliding sleeve 6 of needle point 5 one sidepiece, described axial extension 8 is flexure strip, is provided with back-moving spring 9 between described sliding sleeve 6 and sleeve 3.
Work process of the present invention: when needle tubing does not penetrate skin and flesh, due to the restriction of sliding sleeve 6, first guide pad 71 and the second guide pad 72 pairs of universal pipe joints 4, makes needle tubing general performance be rigidity, is convenient to penetrating of needle tubing; Along with needle point progressively penetrates in skin and flesh, skin first touches axial extension 8, and promote it and move axially, sliding sleeve 6 is driven to slide axially, until sliding sleeve 6 and the second guide pad 72 are separated, the restriction of universal pipe joint 4 is removed, and the needle tubing part making to penetrate skin and flesh realizes universal connection with the needle tubing part not penetrating skin and flesh and syringe etc., ensures that needle tubing can not fracture in skin and flesh.
The foregoing is only preferred embodiment of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to covering scope of the present invention.
