Preferably, a rubber pad is arranged on the inner wall of the fixed bayonet.
Preferably, the pressing plate is arranged on the back side of the insertion end of the fixed bayonet, so that the pressing plate can rotate to be consistent with the opening of the fixed bayonet.
Preferably, the fixing frame is provided with a baffle for positioning, the baffle is arranged on the front side of the pressing plate, the lower end of the pressing plate is provided with a notch, the baffle faces towards one side of the pressing plate and is provided with a rotating lock catch, and the notch penetrates through the rotating lock catch to be fixed through rotating the pressing plate.
Preferably, the rubber pad is made of styrene butadiene rubber.
The technical scheme of the embodiment of the utility model has following advantage and beneficial effect at least: the utility model discloses a needle fixer when using, accomplish the extraction back with the syringe needle that the needle tubing cup jointed to the liquid in the infusion bottle, operating personnel goes into the downside of infusion bottle bottleneck flange department with this fixer through fixed bayonet socket card, rotate the clamp plate simultaneously towards syringe needle and needle tubing connection department, make the breach card of insertion frame department go into, operating personnel extracts the needle tubing and the syringe needle has certain dilatory displacement along its extraction direction, contact and avoid further removal when insertion frame and syringe needle interface department, thereby operating personnel singlehanded can realize the separation work to needle tubing and syringe needle, the use that has made things convenient for operating personnel and more laborsaving in many times of test process.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Example 1
As described in further detail below with reference to the specific embodiments, referring to fig. 1 to 4, embodiment 1 is a needle holder, which includes a fixing frame 1, where the fixing frame 1 is provided with a fixing bayonet 2 for being fixed to a flange of a bottle mouth of a liquid storage bottle 8 in a clamping manner; the fixed frame 1 is hinged with a pressing plate 3, the front end of the pressing plate 3 is provided with an inserting frame 31 with a notch in the middle, and the inserting frame 31 presses the edge of the inserting port of the needle head 9 by rotating the pressing plate 3, so that the needle head 9 can be fixed. In particular, a flange is arranged at the bottleneck of a general medical liquid storage bottle 8, after a fixing bayonet 2 with the caliber smaller than that of the flange is clamped at the lower end of the bottleneck flange, an operator rotates a pressing plate 3 to an inserting frame 31 and clamps the connecting part of a needle tube and the needle tube 9 without hindering the extraction of the needle tube, so that after the operator takes the liquid, the operator drives the needle tube 9 to carry out dragging displacement with a certain length when the needle tube is extracted, and when the edge of the inserting port of the needle tube 9 contacts two supporting plates of the inserting frame 31, the needle tube is stressed and blocked, thereby realizing the separation between the needle tube and the needle tube 9, because in the biomedical field, particularly in one-time test of production and storage of stem cells and immune cells, the needle tube can be used for extracting a plurality of disposable needle tubes 9, and in order to avoid pollution, the liquid storage bottle 8 and the needle tubes 9 after being taken each time are used as disposable medical garbage, when liquid is required to be extracted for a plurality of times, the needle tube can be directly inserted into the insertion port of the new disposable needle 9, and the needle fixer can be repeatedly used for a plurality of times, so that the problem that the injector is difficult and inconvenient to pull out frequently after the liquid is extracted is avoided.
The inner wall of the fixed bayonet 2 is provided with a rubber cushion 6. Specifically, it is fixed in the middle of the bottleneck to block in the middle of the extrusion deformation that possesses the certain degree through setting up this cushion 6 to more firm stable under the effect of great stiction, the syringe needle 9 to its drawing liquid of the multiple bore stock solution bottle 8 of applicable an within range is fixed simultaneously.
The pressing plate 3 is arranged on the back side of the insertion end of the fixed bayonet 2, so that the pressing plate 3 can rotate to be consistent with the opening of the fixed bayonet 2. Specifically, the arrangement in this direction is beneficial for the operator to clamp the fixing frame 1 of the needle head fixer into the bottle mouth and then rotate the pressing plate 3 to the upper end of the needle head 9.
The rubber cushion 6 is made of styrene butadiene rubber. Specifically, the rubber pad 6 made of the material has the advantages of wear resistance, pressure resistance and aging resistance, and can be used for a long time.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
