Description
Technical field
The utility model is related to a kind of medical instrument more particularly to disposable ending blood taking needles.
Background technology
Disposable ending blood taking needle currently on the market mostly uses internal ejection structure, cancels after first use, to keep away
Exempt to reuse.Meanwhile existing ending blood taking needle needs for the blood sampling of different crowd, is provided with different specifications, and main
If puncture dynamics is controlled by the way that needle length and aciculiform is arranged, therefore blood taking needle of the same race is poor for applicability, especially in needs such as hospitals
A large amount of occasions for carrying out tip blood sampling, consume a large amount of cost, have seriously affected working efficiency, and existing blood taking needle holds in addition
It is quick detachable, it is beaten or is easy to fall apart when falling, reused after can neither effectively avoiding criminal from recycling, again
It cannot be guaranteed that the safety for the treatment of of!medical waste personnel.
Therefore, it is necessary to one kind, and puncture dynamics can either be adjusted flexibly so that and a kind of specification product is applicable to all groups,
The new product reused is prevented simultaneously.

Specific implementation mode
The utility model is described further with reference to embodiment and attached drawing.
A kind of disposable ending blood taking needle, including adjusting slider 1, sleeve 2, syringe needle 3, hollow pushing block 5；2 liang of the sleeve
End opening, the adjusting slider 1, pushing block 5 are each passed through both ends open and sleeve 2 is slidably connected；The sleeve 2 is slided close to adjusting
On 1 one end inner wall of block, corresponding both sides be symmetrically arranged with screens protrusion 2-1, on 2 other end inner wall of the sleeve, corresponding
Monosymmetric be provided with 2 screens contact 2-2；The length that the adjusting slider 1 is located at one end in sleeve 2 is more than two cards
Length between the protrusion 2-1 of position；The syringe needle 3 is located in sleeve 2, and between adjusting slider 1 and screens contact 2-2；Institute
Adjusting slider 1 is stated to connect with 3 pedestal of syringe needle by spring 4；The distance between described free ends 2 screens contact 2-2 are less than needle
The length of first 3 pedestal；The pushing block 5 is located at the length and 2 screens contacts of the length more than corresponding end opening of one end in sleeve 2
The distance between free ends 2-2；The syringe needle 3 across screens contact 2-2 be located at pushing block 5 it is hollow in, and its front end is no more than and pushes away
Block 5.
One end that the sleeve 2 is provided with pushing block 5 is provided with needle guard 6.
The quantity per side screens protrusion 2-1 is 3, corresponding with each screens protrusion 2-1 on 2 outer wall of the sleeve
Position be provided with length scale.
The material of the screens protrusion 2-1 is flexible plastic or rubber.
Length between two opposite screens protrusion 2-1 is less than the length of 2 adjusting slider of sleeve, 1 end opening.
2 screens contact 2-2 are tilted to 1 one end of adjusting slider；
The free ends screens contact 2-2 are spherical shape.
As shown in Figure 1, the utility model is made of adjusting slider 1, sleeve 2, syringe needle 3, spring 4, pushing block 5 and needle guard 6,
The interior side of middle sleeve 2 is equipped with equally distributed screens protrusion 2-1, and the other side is equipped with screens contact 2-2；Screens protrusion 2-1
It is integrally formed, can not dismantle with screens contact 2-2 and sleeve 2；The position of the corresponding screens protrusion in 2 outside of sleeve, which is equipped with, carves
Degree；One end ground of the adjusting slider 1 inside sleeve 2 is connected with spring 4；Syringe needle 3 is the medical needle for having pedestal, one
End is connect by spring 4 with adjusting slider 1, can not be dismantled.
The screens contact 2-2 is the shape such as spheroidal of ultimate swelling, is offseted with the pedestal of syringe needle 3 when being not used
It touches so that syringe needle 3 can not stretch out sleeve 2.
The pushing block 5 is hollow, and one end is in the inside of sleeve 2, and its length is more than the Opening length of sleeve 2, to nothing
Method is deviate from from sleeve 2, and on the outside of screens contact 2-2.
The needle guard 5 is dismountable, closely surrounds the plastic sheath of 2 one end of sleeve.
When the utility model is used according to the difference of PATIENT POPULATION, by the operator that takes a blood sample according to PATIENT POPULATION's difference, pressing
Adjusting slider 1 is to different scales, so that internal 4 deformation degree of spring gradually increases, plays and adjusts puncture dynamics
Effect；It is specific as follows：Screens protrusion 2-1 plays the role of positioning to adjusting slider 1, since screens protrusion 2-1 is soft rubber
Or plastic material, when original state, adjusting slider 2-1 is without pressed by external force, due to the blocking of outermost screens protrusion 2-1, and by
Obstruction in 2 open end of sleeve, 1 inner end of adjusting slider are located between outermost screens protrusion 2-1 and the opening of sleeve 2, at this time bullet
Spring is in relaxed state, and the needle stand of syringe needle 3 is located in sleeve inner by screens contact 2-2, and syringe needle is from two screens contacts
It is passed through among 2-2, is located in the hollow part of pushing block 5；In use, according to patient profiles, medical worker judges required elastic force, from
And adjusting slider 1 is pressed to corresponding scale, needle guard 6 is removed after adjusting, 5 outer end of pushing block is placed in site of puncture, firmly
It presses, it is inside pushing block 5 that screens contact 2-2 is open-top so that syringe needle 3 launches, and completes to puncture.
In order to make screens protrusion 2-1 that can play positioning action to adjusting slider 1 but also make it can in external force
With movement, screens protrusion 2-1 is soft rubber or plastic material, and material itself has certain elasticity and deformation restores energy
Power can control the length between two screens protrusion 2-1 to be less than the length of 2 adjusting slider of sleeve, 1 end opening in terms of difference in height
Range in 2-4mm, i.e. the length difference of unilateral side screens protrusion 2-1 and corresponding side adjusting slider 1 is 1-2mm.
Although this specification has more used 1-adjusting slider, 2-sleeves, 2-1-screens protrusion, 2-2-screens
Contact, 3-syringe needles, 4-springs, 5-pushing blocks, the terms such as 6-needle guards, but the possibility using other terms is not precluded.Make
With these terms just for the sake of more easily describing the essence of the utility model, it is additional to be construed as any type
Limitation is all contrary to the spirit of the present invention.
It should be understood that the part that this specification does not elaborate belongs to the prior art.
It should be understood that the above-mentioned description for preferred embodiment is more detailed, can not therefore be considered to this
The limitation of utility model patent protection domain, those skilled in the art are not departing under the enlightenment of the utility model
Under the ambit that the utility model claims are protected, replacement or deformation can also be made, the utility model is each fallen within
Within protection domain, the utility model is claimed range and should be determined by the appended claims.
