When intramuscular injection medicine is added, the injector is held by the right hand, the medicine bottle is held by the left hand, the needle is aligned with the bottle stopper to penetrate into the medicine bottle, and the latex protective sleeve is penetrated while the medicine bottle is penetrated. After the medicine is added and the needle is pulled out, the elastic latex protective sleeve automatically restores to the original position by virtue of the elasticity of the elastic latex protective sleeve, and the needle is covered, so that the aims of puncture prevention, pollution prevention and cross infection prevention are achieved.
The above scheme realizes the protection of the needle by utilizing the elastic latex protective sleeve, and the protection of the needle can be recovered by the self elasticity of the elastic latex protective sleeve after the injection, but the syringe is not beneficial to the injection of doctors because the elastic latex protective sleeve always coats the needle.
Disclosure of Invention
The utility model discloses a protective device for a syringe for preventing needle puncture and the syringe, which solve the problem that the prior syringe is not beneficial to doctor injection when the needle is safely protected.
In order to achieve the above purpose, the technical scheme provided by the utility model is as follows:
the utility model provides a protector for syringe that prevention needle stabs, includes the sleeve of pegging graft with the syringe, four L shape spouts have been seted up to circumference equidistance on the sleeve, every the length of all being not less than the length of syringe needle of vertical setting on the spout, four common sliding connection has the protection casing in the spout, the upside of protection casing is equipped with four sliding connection's traveller in the spout, the through-hole that the diameter is not less than the syringe needle has been seted up to the bottom of protection casing, the inside downside of protection casing still is equipped with the spring.
Preferably, a clamping groove which is clamped with the sliding column is arranged on the side of the sliding groove which is transversely arranged.
By adopting the scheme, the sliding column can be limited by the aid of the clamping groove, so that the stability of the scheme is enhanced.
Preferably, the same side of the sleeve and the protective cover is embedded with an observation window, and the observation window is opposite to the scale mark of the needle cylinder in the injector
By adopting the scheme, the scale marks on the injector can be conveniently observed.
Preferably, a rubber plug is arranged at the through hole.
By adopting the scheme, the rubber plug can prevent external dust from entering the protective cover to pollute the needle, and meanwhile, the residual liquid medicine on the needle after injection can be ensured not to drop to the ground, so that the problem of environmental pollution is avoided.
According to another technical scheme provided by the utility model, the protection device of any one of the above is applied to the syringe.
Compared with the prior art, the utility model has the beneficial effects that:
the technical scheme has simple structure, is convenient to manufacture, is favorable for large-scale popularization and application, can be matched with the existing injector for use, does not need to improve the existing injector, and enlarges the application range of the technical scheme.
Drawings
FIG. 1 is a schematic view of the structure of the syringe of example 1 when not in operation;
fig. 2 is a schematic view of the structure of the shield in embodiment 1 when rotated.
The names of the corresponding marks in the drawings are: the syringe 1, sleeve 2, spout 3, draw-in groove 4, protection casing 5, traveller 6, rubber buffer 7, spring 8.
Detailed Description
The utility model is described in further detail below with reference to the attached drawings and embodiments:
example 1
As shown in fig. 1 and 2, a protection device for a syringe for preventing needle stick injury comprises a sleeve 2 inserted into a syringe 1, wherein a layer of rubber pad is attached to the inner wall of the sleeve 2, so that an anti-slip function can be achieved in the process of inserting the syringe 1, and the stability of the scheme is enhanced. Four L-shaped sliding grooves 3 are circumferentially equidistant on the upper side of the sleeve 2, the side length of each sliding groove 3 which is vertically arranged is not smaller than the length of the needle, and the side of each sliding groove 3 which is transversely arranged is provided with a clamping groove 4 which is clamped with the sliding column 6. The four sliding grooves 3 are connected with a protective cover 5 in a sliding manner, the same sides of the sleeve 2 and the protective cover 5 are embedded with observation windows, the observation windows are opposite to scale marks of a needle cylinder in the injector 1, and the scale marks on the injector 1 can be conveniently observed by means of the observation windows. The upper side of the protective cover 5 is provided with four sliding columns 6 which are in sliding connection in the corresponding sliding grooves 3, the sliding columns 6 are made of rubber materials, the center of the bottom of the protective cover 5 is provided with a through hole with the diameter not smaller than that of a needle, and the through hole is provided with a rubber plug 7 which can protect the needle by means of the rubber plug 7. The lower side of the interior of the protective cover 5 is also provided with a spring 8.
The working process of the scheme is as follows:
when the protective device is used, the sleeve 2 is inserted outside the injection cylinder of the injector 1, then the four slide posts 6 slide into the corresponding slide grooves 3, the slide posts 6 fall into the bottoms of the edges vertically arranged in the slide grooves 3, at the moment, the needle of the injector 1 is positioned behind the protective cover 5, and the spring 8 does not abut against the bottom of the needle cylinder of the injector 1, so that the protection of the needle is realized.
When injection is needed, firstly, the protective cover 5 is moved upwards, the protective cover 5 is rotated into the clamping groove 4 after the sliding column 6 is moved to the intersection of the sliding grooves 3, in the process of moving the protective cover 5, the needle head of the syringe 1 passes through the rubber plug 7, at the moment, the spring 8 in the protective cover 5 is propped against the bottom of the syringe 1, and the spring 8 is in a compressed state. The sucking and injecting work of the liquid medicine can be realized through the needle head extending out of the protective cover 5, after the injection is finished, the sliding column 6 slides out of the clamping groove 4, then the protective cover 5 is rotated to the intersection of the sliding groove 3, at the moment, the protective cover 5 rapidly slides down to the vertical lowest position of the sliding groove 3 under the action of the gravity of the protective cover and the elasticity of the spring 8, so that the needle head of the injector 1 is protected again, the problem that the needle head stabs staff in the transportation process is prevented, and the safety of the scheme is improved.
