Abstract
Disclosed by the utility model is a kind of fixed device of injector needle cap of medical instruments field, including fixed frame and the c-type bayonet being arranged on fixed frame, the middle inside of the c-type bayonet is equipped with annular groove, the internal diameter of the c-type bayonet and the middle and upper part outer diameter of injector needle cap are identical, the opening of c-type bayonet is greater than the outer diameter of syringe needle handle, and the internal diameter of the annular groove is identical as outer diameter where a circle boss of injector needle cap opening.The beneficial effects of the utility model are: having the c-type bayonet of annular groove by setting one, it takes and penetrates needle cap from top to bottom when cap, it carries out taking cap after blocking the boss of needle cap opening using annular groove, syringe needle is inserted into needle cap when returning set, needle cap is detached from after annular groove to take out from the opening of c-type bayonet again, complete back set operation, whole process is convenient and efficient, medical staff's one hand is improved to take cap and return the efficiency of cap, the risk for effectively avoiding its hand from being stabbed by syringe needle.
Description
Technical field
The utility model relates to medical instruments field more particularly to a kind of fixed devices of injector needle cap.
Background technique
Currently, medical staff generally requires one-handed performance when being carried out with syringe and being taken medicine and injection, one of ratio
Cumbersome step is exactly that taking for injector needle cap covers and return set.It is also easier when removing to take set, need to only use thumb and index finger
Peeling, but bad operation when set is returned, because needle cap is typically in laid-flat status after being removed, one hand is not easy to provoke needle
Cap easily causes needle to stab, and the harm such as transmission increases the difficulty and risk of medical care precess.
Utility model content
For overcome existing one-handed performance take set and return set during above shortcomings, it is to be solved in the utility model
Technical problem is: providing a kind of for assisting the fixed device of the singlehanded injector needle cap for taking set and returning set.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
Injector needle cap fixes device, including fixed frame and the c-type bayonet that is arranged on fixed frame, the c-type bayonet
Middle inside is equipped with annular groove, and the internal diameter of the c-type bayonet and the middle and upper part outer diameter of injector needle cap are identical, c-type bayonet
Opening is greater than the outer diameter of syringe needle handle, and the internal diameter of the annular groove and the one of injector needle cap opening enclose boss institute outside
Diameter is identical.
Further, the inner wall of the c-type bayonet is in up big and down small pyramidal structure, the taper phase of taper and needle cap
Together.
Further, the c-type bayonet is made of plastic material.
Further, the thickness of the c-type bayonet is located at 1~2mm.
Further, the upper end of the fixed frame is equipped with downward opening groove, the lower end of fixed frame is equipped with locking screw
Bolt, clamping screw are threadedly coupled with fixed frame, groove of the head towards fixed frame upper end.
The beneficial effects of the utility model are: the c-type bayonet of annular groove is had by setting one, by needle cap when taking cap
It penetrates from top to bottom, carries out taking cap after the boss of needle cap opening is blocked using annular groove, insert syringe needle when returning set
Enter needle cap, be detached from needle cap after annular groove and taken out again from the opening of c-type bayonet, completes back set operation, it is whole
A process is convenient and efficient, improves medical staff's one hand and takes cap and return the efficiency of cap, its hand is effectively avoided to be stabbed by syringe needle
Risk.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model c-type bayonet cross-sectional view.
Label is 1- fixed frame, 2-C type bayonet, 3- annular groove, 4- fastening bolt in figure.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, the utility model includes fixed frame 1 and the c-type bayonet 2 that is arranged on fixed frame 1, the C
The middle inside of type bayonet 2 is equipped with annular groove 3, the middle and upper part outer diameter phase of the internal diameter and injector needle cap of the c-type bayonet 2
Together, the opening of c-type bayonet 2 is greater than the outer diameter of syringe needle handle, internal diameter and the injector needle cap opening of the annular groove 3
Outer diameter where one circle boss is identical.
The practical process of the utility model is: whole device being fixed on treatment center using fixed frame 1 in advance, works as needs
When carrying out that cap is taken to operate, injector needle cap end is penetrated from the top of c-type bayonet 2, since the opening of needle cap is convex equipped with a circle
Platform, during insertion, boss first strut c-type bayonet 2, are then blocked by annular groove 3, gently mention upwards again after needle cap is fixed
Syringe just completes and cap is taken to operate；When carrying out back cap operation, the syringe needle of syringe is worn above c-type bayonet 2
Enter, syringe needle enters needle cap and connect with needle cap, slightly firmly pulls down syringe again at this time, connect needle cap with syringe needle tightly
Gu and making needle cap be detached from annular groove 3 and c-type bayonet 2, then needle handle position is completed back from the removal of the opening of c-type bayonet 2
Cap operation.
In order to enable c-type bayonet 2 to play preferable firm effect to needle cap, the inner wall of the c-type bayonet 2 is arranged to
Up big and down small pyramidal structure, taper is identical as the taper of needle cap, to increase the contact area of c-type bayonet 2 Yu needle cap, from
And keep the two connection more stable and reliable, needle cap will not be made to be detached from c-type bayonet 2 because of shaking.
Due to requiring to strut c-type bayonet 2 during taking cap and returning cap, it is therefore desirable to which c-type bayonet 2 has preferable bullet
Property, so being made preferably with plastic material.In view of the size of syringe and convenient for taking cap and time cap, the c-type
The thickness of bayonet 2 should be located at 1~2mm.
Fixed frame 1 is fixed on treatment center for convenience, is equipped with downward opening ditch in the upper end of the fixed frame 1
Slot, the lower end of fixed frame 1 are equipped with clamping screw 4, and clamping screw 4 is threadedly coupled with fixed frame 1, and head is towards on fixed frame 1
The groove at end.First the groove of 1 upper end of fixed frame is hung on the guardrail for the treatment of center when use, then rotation lock bolt 4, is locked
4 head of bolt is against on guardrail, and whole device is fixed.
The utility model is fixed needle cap by the fixed device of one simple needle cap of setting, improves medical care people
The singlehanded accuracy and efficiency for taking cap and returning cap of member, the risk for effectively avoiding its hand from being stabbed by syringe needle have practical well
Property and application prospect.
