Description
Technical field
The present invention relates to a kind of medical instruments, and in particular to a kind of medical needle answers cap device.
Background technique
In the medical field, aseptic parenteral solution often is added in drug using syringe and direct injection enters patient's
In vivo.Existing syringe includes syringe, syringe needle and needle cap, when being injected using syringe, needs to take needle cap
Under, when taking needle cap and when being inserted in needle cap on syringe needle again, it is easy to accidentally injure operator, there is the danger for causing blood borne disease to propagate
Danger.
Needle cap is covered to the process also referred to as cap operation again on syringe needle again after the completion of injection.Original way is on the other hand
There is the syringe of syringe needle to carry out multiple cap operation for holding needle cap, the other hand holding.Either needle cap is put on the table, on the other hand holding tool
There is the syringe of syringe needle, in the case that other objects stop needle cap on the table, inserts the needle into needle cap and realize multiple cap operation.But
Above two mode of operation is easy to cause needle to stab, and seriously endangers the personal safety of medical staff, and above two operation
There are many sufferings and inconvenience in mode.
In response to the above problems, entitled " a kind of syringe needle answer cap device ", Patent No.: 201220023289.5, Granted publication
Number are as follows: the Chinese utility model patent of CN 202459647U provides solution, is mainly characterized in that a kind of " syringe needle
Multiple cap device, including upper cross plate, middle transverse slat and riser, are respectively equipped with upper cross plate and middle cross between the upper end and middle part of two risers
To be arranged in parallel and between each other there are spacing, the upper cross plate is equipped with a plurality of sizes for plate, the upper cross plate and middle transverse slat
Different through-hole, middle transverse slat are equipped with the needle cap putting hole corresponding and equal quantity with upper cross plate through-hole.Though " its energy elementary solution
The certainly above problem, but still can have the following deficiencies:
1, the syringe of syringe is needed during multiple cap through through-hole 3, thus very likely occur syringe needle and through-hole 3 or
The phenomenon that upper cross plate 5 where through-hole 3 is in contact, causes syringe needle to be contaminated.
2, needle cap only passes through 6 single hole of needle cap putting hole and is positioned, and can not be formed to leptosomatic needle cap good
Constraint positioning, it is most likely that there is a phenomenon where needle caps to deflect, and causes syringe needle that can not be inserted into.
3, the mechanism that any pair of needle cap plays clamping action is had no in needle cap putting hole 6, causes needle cap putting hole 6 that can not press from both sides
Tight needle cap, therefore the needle cap after pulling out can only individually be filled in needle cap putting hole 6 and just can be carried out subsequent multiple cap operation, not
It is able to achieve the operation for pulling out needle cap.
Summary of the invention
The purpose of the present invention is: it redesigns a kind of medical needle and answers cap device, it can be achieved that pulling out needle cap and multiple cap operation, keep away
Exempt from the bad phenomenon that needle is stabbed, while syringe needle being avoided to be contaminated, provides convenience for medical staff.
To achieve the goals above, the present invention provides the following technical solution:
A kind of medical needle answers cap device, including matrix and needle cap clamping positioning mechanism；Described matrix includes the first positioning
Plate, the second positioning plate and needle cap clamping plate, first positioning plate are connect with the second positioning plate and needle cap clamping plate respectively, and described

There is needle cap through-hole 2, fixed anti-skidding clip pad 20 is provided in needle cap through-hole 2, is provided with needle cap on second positioning plate 11
Blind hole 3, needle cap through-hole 2 and 3 same axis of needle cap blind hole, the opening of needle cap blind hole 3 is towards needle cap through-hole 2, the needle
Cap blind hole 3 is for positioning the end point of needle cap, the bad phenomenon for avoiding needle cap from deflecting；Needle cap clamps positioning
Mechanism 4 is located in needle cap clamping plate 12 and the glide direction of needle cap clamping positioning mechanism 4 and the axial direction of needle cap through-hole 2 are perpendicular,
The anti-skidding clip pad 42 of sliding is provided on needle cap clamping positioning mechanism 4, the anti-skidding clip pad 42 of sliding is located in needle cap through-hole 2
And it is matched with the position of the anti-skidding clip pad 20 of fixation, the anti-skidding clip pad 42 of sliding and the fixed anti-skidding realization pair jointly of clip pad 20
The clamping of needle cap positions.
Needle cap clamping plate 12 is specially to be flexibly connected with the connection of the first positioning plate 10, i.e., needle cap clamping plate 12 and second is determined
Adjustable interval between the plate 11 of position, to adapt to the needle cap of different length specification.
Gap between second positioning plate 11 and needle cap clamping plate 12 can be used for the processing that carries out disinfection to needle cap blind hole 3.
Needle cap clamping positioning mechanism 4 includes sliding shoe 40, fastening spring 43 and button 44；On the sliding shoe 40
It is provided with straight line through slot 41, straight line through slot 41 plays resigning, and the anti-skidding clip pad 42 of sliding is located in straight line through slot 41.
The button 44 and fastening spring 43 are connect with the both ends of the length direction of sliding shoe 40 respectively, and the sliding is anti-skidding
Clip pad 42 is particularly located at straight line through slot 41 close to one end of fastening spring 43.
The button 44 protrudes end face of the needle cap clamping plate 12 far from 10 one end of the first positioning plate, and the button 44 is for being convenient for
Manual actuation sliding shoe 40 is slided；The button 44 is located on the extended line of the axis of fastening spring 43, the clamping bullet
Spring 43 is in compressive state, and the fastening spring 43 is for providing lasting elastic force to sliding shoe 40；The width of the straight line through slot 41
Degree is matched with the diameter of needle cap through-hole 2.
Fastening positioning mechanism 5, the fastening localization machine are provided on first positioning plate 10 and the second positioning plate 11
Structure 5 is particularly located at end face and second positioning plate 11 end far from needle cap clamping plate 12 of first positioning plate 10 far from needle cap clamping plate 12
Face.
It can allow fastening positioning mechanism 5 and desktop and/or wall surface on the first positioning plate 10 and/or the second positioning plate 11
Be fixedly connected, needle cap through-hole 2 and the axis of needle cap blind hole 3 be parallel to the horizontal plane or vertically, so as to keeping syringe needle horizontal or
