Description

Insulin injection pen convenient to needle change
Technical Field
The utility model relates to an insulin injection pen convenient to needle changing.
Background
The insulin injection pen occasionally breaks the needle during use, at which time the needle needs to be replaced. The problems with needle replacement are as follows: firstly, when the spare needle is not carried, the needle cannot be replaced in time; secondly, the broken needle that is dismantled can not be abandoned at will, has not had the place that can accomodate temporarily.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an insulin injection pen convenient to trade needle aims at solving above-mentioned problem.
In order to achieve the purpose, the technical scheme of the utility model is to design an insulin injection pen convenient for needle replacement, which comprises a pen cap, a pen body, a needle head and an end cap;
the interior of the pen cap is divided into an upper part and a lower part by a first partition plate, a second partition plate is arranged at the lower end of the lower part of the pen cap and divides the lower part of the pen cap, and a threaded hole is formed in the second partition plate; the needle head comprises a needle tube, a needle head main body, a needle head upper part thread end and a needle head lower part thread end; the upper threaded end and the lower threaded end of the needle head are respectively arranged on the upper end surface and the lower end surface of the needle head main body, and the needle tube penetrates through the upper threaded end of the needle head; a passage with a wide lower part and a narrow upper part is arranged between the threaded end at the lower part of the needle head and the needle head main body and is connected with the needle tube; the threaded end of the upper part of the needle head is in threaded connection with the threaded hole of the second partition plate; the inner wall of the end cover is provided with internal threads, and the end cover is connected with the threaded end at the lower part of the needle head through threads.
Furthermore, the threaded end of the lower part of the needle head is connected with the pen body in a threaded connection mode.
Further, the thread fastening direction of the thread hole on the second partition plate and the thread end on the upper part of the needle head is opposite to the thread fastening direction of the thread end on the lower part of the needle head and the end cover.
When the needle needs to be replaced, the end cover is firstly rotated along the fastening direction of the end cover and the lower threaded end of the needle head, and the fastening direction of the lower threaded end of the end cover and the needle head is opposite to the fastening direction of the threaded hole in the second partition plate and the upper threaded end of the needle head, so that the upper threaded end of the needle head can be screwed out of the threaded hole in the second partition plate by rotating the end cover along the fastening direction of the lower threaded end of the end cover and the needle head, the spare needle head is taken out, then the end cover is unscrewed reversely, and the broken needle head. And finally, screwing the lower threaded end of the broken needle head and the end cover, screwing the upper threaded end of the broken needle head into the threaded hole in the second partition plate to complete temporary storage of the broken needle, and taking out the broken needle when a container capable of processing the broken needle is found.
The utility model has the advantages and the beneficial effects that: the utility model relates to an insulin injection pen convenient to trade needle can portable reserve syringe needle, its simple structure, convenient to use.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the disassembly of each component of the present invention.
Fig. 3 is a cut-away schematic view of the pen cap, needle and end cap.
