Background
Syringes are a common medical device. The injector consists of a syringe with a small hole at the front end and a matched piston core rod, and is used for injecting a small amount of liquid or extracting the liquid or the liquid from the inaccessible area by other methods, wherein the liquid or gas is sucked from the small hole at the front end of the syringe when the core rod is pulled out, and the liquid or gas is extruded when the core rod is pushed in.
Syringes typically include a needle, a needle cover, a plunger structure, the needle cover having a needle cover before injection, and after injection is completed, the needle and needle cover are typically thrown to a medical waste collection site, but the exposed needle is sharp and prone to personal injury and infection.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a syringe with flexible needle cover, aim at solving the above-mentioned problem that proposes.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an injection syringe with flexible needle cover, includes injection syringe, syringe needle cover, scalable needle cover, syringe needle bottom is fixed with the pintle, and the syringe needle passes through the pintle and installs in the injection syringe upper end, and the pintle is close to the injection syringe end and is fixed with scalable needle cover, after the syringe needle cover, scalable needle cover can be pushed out and extend, flexible needle cover highly is higher than the syringe needle height when extending.
Further, scalable needle cover includes fixed cover, sliding sleeve, fixed cover is fixed in the pintle side, and the sliding sleeve is equipped with a plurality ofly altogether, all can carry out the relative slip between per two sliding sleeves, along fixed cover towards the syringe needle direction, the sliding sleeve internal diameter reduces in proper order, two sliding sleeve roll-off positions department, the sliding sleeve inner wall radius is the same.
Furthermore, a shifting sheet is fixed at the upper end of the sliding sleeve positioned at the innermost part of the fixed sleeve, and the shifting sheet is symmetrically arranged relative to the middle part of the sliding sleeve.
The utility model discloses a substantive characteristics lie in with the technological progress that is showing: (1) the retractable needle sleeve is fixed on the periphery of the pintle, the needle head sleeve is sleeved outside the needle head before the syringe is used, so that the exposed needle head is prevented from being punctured, the potential safety hazard is reduced, the retractable needle sleeve can be pushed out after the injection is finished, the exposure of the needle head is prevented, and the operation is simple and convenient; (2) the utility model discloses mutually noninterfere between syringe needle cover and the scalable needle cover, in the transportation, use syringe needle cover to establish in the syringe needle outside, do not have the problem of the extranal packing of syringe needle puncture in the transportation.
Drawings
Fig. 1 is a schematic structural view of a syringe with a retractable needle sheath according to the present invention;
fig. 2 is a schematic drawing showing the extension of the retractable needle sheath of the syringe with the retractable needle sheath according to the present invention.
In the figures, the reference numerals have the meaning: 1-syringe, 2-syringe needle, 3-syringe needle cover, 4-telescopic needle cover, 5-pintle, 6-fixed cover, 7-sliding sleeve, 8-plectrum.
Detailed Description
In order to further understand the contents, features and functions of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, a syringe with a retractable needle sheath according to an embodiment of the present invention will be described in detail.
The syringe with the telescopic needle sleeve comprises a syringe 1, a syringe needle 2, a needle cover 3 and a telescopic needle sleeve 4, wherein a pintle 5 is fixed at the bottom of the syringe needle 2, the syringe needle 2 is installed at the upper end of the syringe 1 through the pintle 5, the telescopic needle sleeve 4 is fixed at the position, close to the syringe 1, of the pintle 5, the telescopic needle sleeve 4 is higher than the height of the syringe needle 2 when being unfolded, the needle cover 3 is clamped outside the pintle 5, and the telescopic needle sleeve 4 can be pushed out after the needle cover 3 is detached.
Specifically, scalable needle cover 4 is including fixed cover 6, sliding sleeve 7, fixed cover 6 is fixed in the periphery of pintle 5, and sliding sleeve 7 is equipped with a plurality ofly altogether, all can carry out relative slip between two adjacent sliding sleeve 7, along fixed cover 6 towards the syringe needle direction, 7 internal diameters of sliding sleeve reduce in proper order, and 7 roll-off positions departments of two sliding sleeve, 7 inner wall radiuses of sliding sleeve are the same.
Specifically, a shifting piece 8 is fixed at the upper end of the sliding sleeve 7 positioned at the innermost part of the fixed sleeve 6, and the shifting piece 8 is symmetrically arranged relative to the middle part of the sliding sleeve 7.
The poking sheet 8 is propped by fingers to push upwards, all the sliding sleeves 7 are pushed out in sequence, when the sliding sleeves 7 are pushed out to the joint of the two sliding sleeves 7, the sliding sleeves 7 can be fixed because the radiuses of the inner walls of the sliding sleeves 7 at the sliding-out positions of the two sliding sleeves 7 are the same, and the sliding sleeves are prevented from automatically falling off.
The utility model discloses a theory of operation is: when injection is carried out, the needle cover 3 is taken down to expose the needle 2 for injection, and after the injection is finished, the poking piece 8 is pushed upwards to push the sliding sleeve 7 out to cover the whole needle 2.
As can be seen from the above description, the retractable needle sleeve is fixed on the periphery of the pintle, the needle sleeve is sleeved outside the needle before the syringe is used, so that the exposed needle is prevented from being punctured, the potential safety hazard is reduced, the retractable needle sleeve can be pushed out after the injection is finished, the exposure of the needle is prevented, and the operation is simple and convenient; the utility model discloses mutually noninterfere between syringe needle cover and the scalable needle cover, in the transportation, use syringe needle cover to establish in the syringe needle outside, do not have the problem of the extranal packing of syringe needle puncture in the transportation.
Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
