Description
Technical field
The utility model relates to technical field of medical equipment, and in particular to a kind of dust-proof self-destruction syringe.
Background technique
Syringe is a kind of common medical devices, China on the market mass selling and clinically largely use
Syringe is still common disposable syringe, since it does not have self-destructed function, is easy to make by illegal recycling, repeatedly
With generation cross-infection easily causes transmission.And existing syringe does not have a dust reduction capability, syringe and connecting rod it
Between cavity be completely exposed in air, be easily adhered dust and germ, it is very dangerous.
Utility model content
The purpose of the utility model is to overcome the above-mentioned problems in the prior art, provide a kind of dust-proof type self-destroyed note
Emitter.
To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions
:
A kind of dust-proof self-destruction syringe, including syringe needle, syringe, piston, connecting rod and handle, the piston and syringe top
There are gap between end, it is fixed with the dust ring of bucket shape on the inner wall at the syringe lower opening, is set in the connecting rod
There are the two hangnail fixture blocks matched with dust ring, two hangnail fixture blocks are close to the lower surface of dust ring, and two hangnail cards
The distance between block end is greater than the minimum diameter of dust ring, is also provided with safety lock on the barrel at the syringe lower opening
Hole, the safe lockhole offer through-hole on the lower section of dust ring, the connecting rod, and the safe lockhole is mutually passed through with through-hole
It is logical, and run through by a night bolt.
Further, the gap thickness between the piston and syringe top is greater than the thickness of dust ring.
Further, the dust ring and syringe are integrally formed.
Further, the hangnail fixture block and connecting rod are integrally formed.
Further, there are gaps between the dust ring and connecting rod.
The principles of the present invention: when the utility model is used, extraction night bolt, pulls handle to draw injection,
It then begins to inject, after injection, piston reaches syringe top, while hangnail fixture block passes through dust ring, causes this practical new
Type can not reuse to realize self-destruction；Dust ring can be not only used for self-destruction in the utility model, can also effectively prevent
Only in storage, dust germ enters in syringe, ensure that the cleaning health in syringe；In the utility model, safe lockhole leads to
Hole and night bolt match, it is therefore an objective to which preventing from colliding with during transport or storage makes hangnail fixture block pass through dust ring.
The utility model has the following beneficial effects: the utility model is novel in design, structure is simple, can not reuse, prevent
Because of the transmission that cross-infection occurs, while the utility model has dust reduction capability, ensure that the cleaning health in syringe.
Detailed description of the invention
In order to illustrate more clearly of the technical solution of the utility model embodiment, make required for being described below to embodiment
Attached drawing is briefly described, it should be apparent that, the drawings in the following description are merely some embodiments of the present invention,
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings
Other attached drawings.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram after the utility model use；
In attached drawing, parts list represented by the reference numerals are as follows:
1- syringe needle, 2- syringe, 3- piston, 4- connecting rod, 5- handle, 6- dust ring, 7- hangnail fixture block, the safe lockhole of 8-,
9- through-hole, 10- night bolt.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face will combine the attached drawing in the utility model embodiment, carry out to the technical scheme in the embodiment of the utility model clear, complete
Ground description, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Base
In the embodiments of the present invention, institute obtained by those of ordinary skill in the art without making creative efforts
There are other embodiments, fall within the protection scope of the utility model.
Embodiment 1
As shown in Figure 1 and Figure 2, the utility model be a kind of dust-proof self-destruction syringe, including syringe needle 1, syringe 2, piston 3,
Connecting rod 4 and handle 5, it is solid on the inner wall at 2 lower opening of syringe there are gap between 2 top of the piston 3 and syringe
Surely it is equipped with the dust ring 6 of bucket shape, the connecting rod 4 is equipped with the two hangnail fixture blocks 7 matched with dust ring 6, two hangnails
Fixture block 7 is close to the lower surface of dust ring 6, and the distance between two 7 ends of hangnail fixture block are greater than in the minimum of dust ring 6
Diameter, is also provided with safe lockhole 8 on the barrel at 2 lower opening of syringe, the safe lockhole 8 in the lower section of dust ring 6,
Through-hole 9 is offered in the connecting rod 4, the safe lockhole 8 and through-hole 9 connect, and run through by a night bolt 10.
Further, the gap thickness between 2 top of the piston 3 and syringe is greater than the thickness of dust ring 6.
Further, there are gaps between the dust ring 6 and connecting rod 4.
Embodiment 2
As another embodiment of the utility model, the dust-proof self-destruction syringe of the present embodiment is dust-proof with embodiment 1
The structure of self-destruction syringe is essentially identical, the difference is that, the dust ring 6 is integrally formed with syringe 2, the hangnail card
