Abstract
The utility model relates to a mechanical injection pen cap of latent needle formula relates to medical instrument technical field, has overcome the defect that current injection pen used latent needle very few, including the injection syringe, its characterized in that: the pen cap is internally provided with a needle hiding spring and a needle hiding end cover which are screwed and fastened together through the end cover; the utility model discloses the product is equipped with the mechanical injection pen cap of latent needle formula, and the syringe needle can not injure the people when not only getting to put, and is very safe, can not let the people see the syringe needle among the injection process yet, can reduce user's the feared psychology.
Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to mechanical injection pen cap of hidden needle type.
Background
The existing needle hiding function generally appears on an electronic injection pen, and the mechanical pen is rarely used.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an aim at: provides a mechanical injection pen cap with a hidden needle type, which aims to solve the technical problems in the prior art.
According to the above-mentioned purpose, the basic technical scheme of the utility model is: a mechanical injection pen cap of latent needle formula, includes the syringe, its characterized in that: the pen cap is internally provided with a hidden needle spring and a hidden needle end cover which are screwed and fastened together through the end cover.
Furthermore, a cap is also arranged on the injection needle.
Furthermore, when the hidden needle end cover is compressed into the pen cap under the action of external force, the hidden needle end cover drives the hidden needle spring to contract inwards and keep the hidden needle spring axially immobile, and after the injection is finished and the needle head is pulled out, the hidden needle end cover rebounds to the initial state under the action of the hidden needle spring.
Further, when in use, the concealed needle type injection tube is carried out according to the following steps:
a. the mechanical injection tube is provided with a clamping bottle;
b. installing an injection needle;
c. installing a pen cap component;
d. screwing off the end cover;
e. pressing down the hidden needle end cover;
f. removing the cap on the needle head;
h. and (4) injecting.
Compared with the prior art, the utility model discloses an advantage and beneficial effect: the utility model discloses the product is equipped with the mechanical injection pen cap of hidden pin type, and the syringe needle can not injure the people when not only getting and putting, and is very safe, can not let the people see the syringe needle yet among the injection process, can reduce user's the feared psychology.
