Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples：
Embodiment 1：A kind of Dispoable medical syringe needle shielding device, referring to Fig. 1 to Fig. 3；The present apparatus is applied to syringe 1
On.
Specifically, the present apparatus it include sleeve 4, the tail end of described sleeve pipe 4 can be sleeved on the front end of syringe 1.
Further, the middle part in described sleeve pipe 4 is equipped with a ring catch 5, when the tail end of described sleeve pipe is sleeved on syringe
When, the front end of the syringe is withstood on ring catch 5, and the syringe needle 2 on syringe extends forward through the ring catch.
Further, the front end of described sleeve pipe is equipped with the first pillar 6, further includes matched with 6 internal diameter of the first pillar
Second pillar 7, the tail end of second pillar 7 are slidably inserted into the first pillar 6, are further included and 7 internal diameter of the second pillar
Matched third pillar 8, the tail end of the third pillar 8 are slidably inserted into the second pillar 7.
By the way that the second pillar 7 is pulled out out of first pillar, third pillar, which is pulled out out of second pillar, can realize pair
The protection of syringe needle avoids needlestick injuries personnel.
Further, the design also on the front opening of the third pillar 8 covered with by the front end of the third pillar
The film 9 of closure of openings, this film 9 can be used cooperatively after being combined with the present apparatus with one-shot injector, before use, syringe needle
In three pillars, and pass through film 9 and syringe needle is isolated with outside air, avoid extraneous bacterium infection, and working as needs to use
When, it is only necessary to push third pillar, the second pillar into the first pillar can be by puncturing film 9 so as to which syringe needle be leaked by syringe needle
Go out.
Further, the design is also stained with doctor on the medial surface of the film in third pillar by medical adhesive
With aseptic cotton layer, by this Medical antiseptic cotton layer when syringe needle punctures film, this Medical antiseptic cotton layer can to syringe needle outer wall into
Row is disinfected.
Further, in order to avoid the risk that third pillar, the second pillar are drawn out, the design is in first pillar
Front end is equipped with the first annular locating part 11 that internal diameter is less than the first pillar internal diameter, and the tail end of second pillar passes through first
Annular stop part 11 is simultaneously located in the first pillar, and the tail end end of second pillar is equipped with the second annular stop part 12, described
The outer diameter of second annular stop part 12 is more than the internal diameter of the first annular locating part 11.
Similarly, the front end of second pillar 7 is equipped with the third annular stop part that internal diameter is less than the second pillar internal diameter
14, the tail end of the third pillar passes through third annular stop part 14 and in third pillar, the tail end of the third pillar
End is equipped with fourth annular locating part 13, and the outer diameter of the fourth annular locating part is more than the interior of the third annular stop part 13
Diameter.
Further, the phenomenon that being slided in order to avoid the third pillar of pull-out, the second pillar, the design is described
By the middle part of the first pillar, both ends are gradually reduced the internal diameter R of one pillar 6 forwards, backwards, and similarly, the internal diameter R of second pillar is by
Both ends are gradually reduced forwards, backwards at the middle part of two pillars, referring to Fig. 3, are designed by this when third pillar, the second pillar are drawn out,
Since the internal diameter of its first pillar, the second pillar is gradually reduced, fourth annular locating part on third pillar, the second pillar,
Second annular stop part and the first pillar, the second pillar inner wall between frictional force gradually increase, and when the first pillar, second
When pillar is drawn out, the first pillar, the second pillar can be fixed by this frictional force, it is avoided loose phenomenon occur
Occur.
Further, the second annular stop part 12, the fourth annular locating part 13 in the design are flexible rubber
Part.
To sum up, by the use of the present apparatus, the present apparatus can use with syringe detachable, syringe needle can be carried out when in use
Protection, avoids needlestick injuries personnel, avoids the generation of malpractice.
What the embodiment of the present invention was announced is preferred embodiment, and however, it is not limited to this, the ordinary skill people of this field
Member easily according to above-described embodiment, understands the spirit of the present invention, and makes different amplification and variation, but as long as not departing from this
The spirit of invention, all within the scope of the present invention.
