Embodiment
To make those skilled in the art be better understood from technical scheme, below in conjunction with the accompanying drawings and specific embodiment party
Formula elaborates the present invention.
As shown in Figures 1 to 6, embodiment of the invention discloses that a kind of self-destructing safety vein needle shield, the type self-destroyed peace
Full vein needle shield includes anterior sheath 1, rear portion pleated sheet 2, and rear portion pleated sheet 2 is connected to the rear end of anterior sheath 1, front portion shield
The lower part of set 1 sets axially open 3, and anterior sheath 1 can be fastened mutually with rear portion pleated sheet 2, is set in the front portion of anterior sheath 1
A pair of buckle 4,3 end of axially open that buckle 4 is integrally disposed upon anterior sheath 1, at rear portion the rear portion of pleated sheet 2 set it is a pair of with
Be buckled 4 corresponding block button holes 5, and at rear portion, the rear portion of pleated sheet 2 sets two panels revetment 6, and two panels revetment 6 is separately positioned on two cards
The outside of button hole 5.As shown in fig. 6, being provided with taper first 15 on anterior sheath 1, taper first 15 is connected to by connecting rod 14
On anterior sheath 1, rear portion pleated sheet 2 offers through hole 16, after anterior sheath 1 and the mutually fastening of rear portion pleated sheet 2, taper head
15 by deforming through through hole 16.Two tapers first 15 are provided with anterior sheath 1, rear portion pleated sheet 2 offers two through holes
16, after anterior sheath 1 and the mutually fastening of rear portion pleated sheet 2, two tapers first 15 are corresponded to through two through holes 16 respectively.
As described above, after anterior sheath 1 is mutually fastened with rear portion pleated sheet 2, taper first 15 passes through through hole 16, cone
Shape first 15 pass through through hole 16 after can not deviate from from through hole 16 so that sheath after using once can not by anterior sheath 1 with
Rear portion pleated sheet 2 is again turned on, and the sheath of mark had used.
Two panels revetment 6 is fastened and connected with the U-shaped passage 11 in anterior sheath 1 by the first card convex 12 and the second card convex 13.
At rear portion, the rear portion of pleated sheet 2 sets a limited step 7.
One angled protrusions 8 are set at the rear portion of anterior sheath 1, angled protrusions 8 are arranged on the axially open 3 of anterior sheath 1
End, at rear portion, the anterior of pleated sheet 2 sets the limit protrusion 9 coordinated with angled protrusions 8.One is equipped with the bottom of U-shaped passage 11
Convex top 10.
The cross sectional shape of first card convex 12 and the second card convex 13 is triangle, the first card convex of a pair 12 being oppositely arranged be in
On it is barb-like, multipair second card convex 13 being oppositely arranged is in downward barb-like.Barb-like card convex is combinable more
Firmly.
For the blood taking needle of the present embodiment in assembling, pleated sheet 2 collapsed forward in rear portion covers the axially open 3 of anterior sheath 1,
By the cooperation of buckle 4 and block button hole 5, complete vein needle shield is formed, after the completion of assembling, woven hose 18 is arranged on anterior shield
In set 1, the fin of intravenous needle is clipped between anterior sheath 1 and rear portion pleated sheet 2, and syringe needle 17 is stretched out vein needle shield, and
Syringe needle 17 is protected by syringe needle tube (attached drawing is not shown)；In use, removing syringe needle tube, make syringe needle 17 exposed and be pierced into patient's blood
Pipe；；After use, syringe needle 17 is pushed into sheath by fin, is then fed into recycling link, can kept away so in removal process
Exempt to be scratched, avoid infection, this jacket structure is simple, using being also convenient for.
The rear portion of rear portion pleated sheet 2 sets two panels revetment 6, and two panels revetment 6 is separately positioned on the outside of two block button holes 5；
Revetment can enter hole in assembling as the convenient buckle 4 of limiter, and buckle 4 can also be protected to prevent it from causing to anticipate because external force loosens
Come off outside.Triangle card convex is set on two panels revetment 6, in that context it may be convenient to screens, while do not influence buckle 4 and enter hole.Rear portion folds
The rear portion of piece 2 sets a limited step 7, and after needle body slips into sheath, intravenous needle fin is positioned in this 7 back cavity of limited step,
It can prevent needle body from easily falling off sheath, further ensure safety.
The rear portion of anterior sheath 1 sets an angled protrusions 8, and angled protrusions 8 are arranged on 3 end of axially open of anterior sheath 1,
At rear portion, the anterior of pleated sheet 2 sets the limit protrusion 9 coordinated with angled protrusions 8；After angled protrusions 8, limit protrusion 9 coordinate,
The fin of intravenous needle falls into two raised spacing fronts to cooperate, such spacing, can limit syringe needle 17 in infusion
Play is with respect to sheath play.
One inside convex top 10 is set on the front end side wall of anterior sheath 1；This set can make the diameter of sheath slightly
Less than the diameter of woven hose 18, using the elasticity of woven hose 18, woven hose 18 is limited in safety shield, it is this spacing same
Play further safety effect.
To further improve the self-destruction effect of the safety shield of the present invention, in a preferred embodiment of the invention, make
Safety shield is arranged to：The structure of sheath can not be released again after making in needle retraction to sheath.Specifically, such as the institutes of Fig. 2 to 4
Show, the front apron 22 extended towards rear portion pleated sheet 2 is set in the inner side of the front end of anterior sheath 1, in the rear end of anterior sheath 1
Inner side set towards rear portion pleated sheet 2 extend rear position margining plate 23, be provided with upward protrusion in anterior sheath 1
21, in this way, after syringe needle 17 is pushed back in sheath, the middle part of syringe needle 17 is supported by protrusion 22, and rear position margining plate 23 not only limits
The rear end of syringe needle 17 cannot tilt, and limitation syringe needle 17 can not form horizontality, so that syringe needle 17 is located in sheath
Upwarped in head, and the heeling condition of stern settlement, in this way, the head of the syringe needle 17 upwarped is by 22 backstop of front apron, so as to limit
Syringe needle 17 processed is pushed out and uses again, so as to effectively prevent being used again for syringe needle 17.Preferably, 22 court of front apron is made
Rear end extends obliquely downward, in this way, when syringe needle 17 is pushed forward contact front apron 22, front apron 22 is so that the head of syringe needle 17
Further upwarp, and then sheath can not be released.
Further to coordinate front apron 22 and rear position margining plate 23, so that syringe needle is in stable heeling condition, in protrusion
The inclined-plane 20 at bottom and limited step 19 is formed at the same time, after syringe needle 17 is retracted into sheath, be arranged after 21 rear side is high before opening up
Be limited that step 20 is spacing in the end face of the woven hose 18 of syringe needle tail end, and the woven hose 18 of the position be contacted with inclined-plane 20 with
Related syringe needle 17 sticks up state before forming relatively stabilization.
Above example is only the exemplary embodiment of the present invention, is not used in the limitation present invention, protection scope of the present invention
It is defined by the claims.Those skilled in the art can make the present invention respectively in the essence and protection domain of the present invention
Kind modification or equivalent substitution, this modification or equivalent substitution also should be regarded as being within the scope of the present invention.
