The utility model is described in detail below with reference to the figures and examples.
The present invention provides a needle holder for a microneedle, as shown in fig. 1 and 2, comprising: a plate body 1; the plate body 1 is provided with a containing hole 2 for containing injection, a plug hole 3 for plugging a needle body and a dispensing hole 4 for containing glue; one end of the accommodating hole 2 is opened, and the other end of the accommodating hole is communicated with one end of the plug hole 3; one end of the glue dispensing hole 4 is communicated with the other end of the plug hole 3, and the other end of the glue dispensing hole is opened.
In practical application, the needle body is an injection needle body, the inserting hole 3 is matched with the needle body, the input end of the needle body penetrates through the dispensing hole 4 and then is inserted into the inserting hole 3, a gap is reserved between the needle body and the inner wall of the dispensing hole 4, then the glue is dispensed in the gap, dispensing of the needle body is completed, fixing of the needle body is achieved, in the injection process, injection liquid firstly flows through the accommodating hole 2, then enters the needle body from the input end of the needle body, and is injected into skin through the needle body; through the setting of accommodation hole 2, spliced eye 3 and some glue holes 4, need not to run through plate body 1 with the needle body, the grafting of the needle body of being convenient for, and after carrying out some glue to the needle body, can prevent that glue from causing the shutoff to the input of needle body, do not influence the injection entering needle internally.
Specifically, the length ratio of the accommodating hole 2 to the lengths of the plug hole 3 to the glue dispensing hole 4 is 3:1:9, the accommodating hole 2 to the plug hole 3 are communicated with the glue dispensing hole 4 in sequence to form the pinholes, the number of the pinholes is nine in the application, the nine pinholes are arranged in a matrix, the number of the pinholes can be increased or decreased according to actual conditions in other embodiments, and the positions of the pinholes can be adjusted according to actual conditions.
Further, as shown in fig. 2, the accommodation hole 2 has a first opening 21 and a second opening 22; the first opening 21 and the second opening 22 are communicated; the diameter of the receiving hole 2 gradually decreases from the first opening 21 to the second opening 22; the second opening 22 communicates with one end of the insertion hole 3.
Through the setting of accommodation hole 2, and the diameter of accommodation hole 2 reduces from first opening 21 to second opening 22 gradually for accommodation hole 2 can save more injection, and then is convenient for the injection to carry out in bayonet socket 3 through accommodation hole 2, is also convenient for the injection to get into in the needle body of bayonet socket 3 through accommodation hole 2.
Further, the diameter of the second opening 22 is larger than the diameter of one end of the plug hole 3. The diameter through second opening 22 is greater than the diameter of spliced eye 3 one end, has guaranteed that the diameter of accommodation hole 2 is greater than the diameter of spliced eye 3 one end, can prevent that accommodation hole 2 from causing the influence to the grafting of needle body.
Further, as shown in fig. 2, the dispensing hole 4 has a third opening 41 and a fourth opening 42; the third opening 41 and the fourth opening 42 are communicated; the diameter of the dispensing hole 4 is gradually increased from the third opening 41 to the fourth opening 42; the third opening 41 is communicated with the other end of the plug hole 3.
In practical application, the input end of the needle body firstly passes through the fourth opening 42, then passes through the third opening 41, and then enters the inserting hole 3; diameter through some glue holes 4 increases gradually from third opening 41 to fourth opening 42, and the other end intercommunication of third opening 41 and spliced eye 3, and the input of the needle body of being more convenient for gets into in the spliced eye 3, and makes and still leaves the clearance that can hold glue between needle body and some glue holes 4, has guaranteed the some glue operation to the needle body.
Further, the diameter of the third opening 41 is the same as the diameter of the other end of the plug hole 3. The diameter through third opening 41 is the same with the diameter of the spliced eye 3 other end, and the diameter of gluing hole 4 increases from third opening 41 to fourth opening 42 gradually, because spliced eye 3 and the input looks adaptation of needle body, make the input looks adaptation of third opening 41 and needle body, insert spliced eye 3 at the input of needle body after, third opening 41 and the lateral wall butt of needle body input, after carrying out the point and gluing, can further prevent that glue in the gluey hole 4 of point from getting into spliced eye 3 in, thereby further prevent that glue from causing the shutoff to the input of needle body.
According to the needle base for the micro-needle, the accommodating hole 2, the inserting hole 3 and the dispensing hole 4 are arranged, so that a needle body does not need to penetrate through the plate body 1, the needle body can be conveniently inserted, the input end of the needle body can be prevented from being blocked by glue after the needle body is dispensed, and the injection liquid can not be influenced to enter the needle body.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the utility model may occur to those skilled in the art without departing from the principle of the utility model, and are considered to be within the scope of the utility model.
