Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to an insulin pen needle. Background Art
[0002] Insulin pen is one of the important tools for diabetic patients to inject insulin. Correct use and management can ensure safe and effective control of blood sugar levels.
[0003] To ensure the safety and hygiene of the injection process, patients must properly clean and disinfect the injection site before injecting insulin. However, sometimes patients forget to bring the necessary disinfection supplies, which can lead to injections without proper disinfection, thereby increasing the risk of local skin infection. Utility Model Content
[0004] The utility model aims to provide an insulin pen needle to solve the above problems existing in the prior art.
[0005] The technical solution of the utility model to solve the above technical problems is as follows:
[0006] An insulin pen needle comprises a needle shell, a needle body and a needle cover, wherein the end of the needle shell is connected to the needle body, the needle cover is arranged on the needle shell to cover the needle body, the needle cover is filled with a sterile sponge, a placement cavity is arranged on the needle cover, an alcohol capsule is placed in the placement cavity, a plurality of through holes are arranged at the connection between the needle cover and the placement cavity, and the material of the placement cavity is a soft material.
[0007] The beneficial effects of the utility model are:
[0008] Before injecting insulin, the patient first connects the end of the needle shell away from the needle body to the insulin pen, then squeezes the alcohol capsule to allow the disinfecting alcohol to flow into the sterile sponge in the needle cover through the through hole, then separates the needle shell from the needle cover, and takes out the sterile sponge containing alcohol in the needle shell to disinfect the injection site. This insulin pen needle comes with alcohol and sterile sponge, which can effectively prevent patients from injecting without proper disinfection due to forgetting to bring disinfectants, reducing the risk of infection at the injection site.
[0009] On the basis of the above technical solution, the present invention can also be improved as follows.
[0010] Furthermore, the needle sleeve is threadedly connected to the needle housing.
[0011] Furthermore, the needle sleeve is in a truncated cone shape, and the placement cavity is arranged at the top end of the needle sleeve.
[0012] Furthermore, a retaining ring is also provided at the bottom of the needle sleeve.
[0013] Furthermore, a sealing film is provided at the bottom of the needle housing. BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 This is a cross-sectional view of the utility model;
[0015] Figure 2 It is a schematic diagram of the overall structure of the utility model.
[0016] In the accompanying drawings, the components represented by the reference numerals are listed as follows:
[0017] 1. needle shell, 2. needle body, 3. needle sleeve, 31. sterile sponge, 33. retaining ring, 4. alcohol capsule, 5. through hole, 6. placement cavity, 7. sealing membrane. DETAILED DESCRIPTION
[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0019] like Figure 1 and Figure 2 As shown, an insulin pen needle includes a needle shell 1, a needle body 2 and a needle cover 3. The end of the needle shell 1 is connected to the needle body 2. The needle cover 3 is arranged on the needle shell 1 to cover the needle body 2. The needle cover 3 is filled with a sterile sponge 31. The needle cover 3 is provided with a placement cavity 6. An alcohol capsule 4 is placed in the placement cavity 6. A plurality of through holes 5 are provided at the connection between the needle cover 3 and the placement cavity 6, and the material of the placement cavity 6 is a soft material.
[0020] Before injecting insulin, the patient first connects the end of the needle shell 1 away from the needle body 2 to the insulin pen, and then squeezes the alcohol capsule 4 to allow the disinfecting alcohol to flow into the sterile sponge 31 in the needle sleeve 3 through the through hole 5, and then separates the needle shell 1 and the needle sleeve 3, and takes out the sterile sponge 31 containing alcohol in the needle shell 1 to disinfect the injection site. This insulin pen needle, which comes with alcohol and sterile sponge 31, can effectively prevent patients from injecting without proper disinfection due to forgetting to bring disinfectants, reducing the risk of infection at the injection site, and before separating the needle shell 1 and the needle sleeve 3, the needle body 2 is located in the sterile sponge 31 soaked with disinfecting alcohol, which can effectively disinfect the needle body 2 and further reduce the risk of infection at the injection site. In a specific implementation, the alcohol capsule 4 is made of polyvinyl alcohol material and can be broken under the action of external force. The placement cavity 6 is made of rubber material. The rubber has good flexibility and can adapt to the deformation of the alcohol capsule 4 during extrusion. At the same time, it has a certain rigidity in the absence of external force, protecting the alcohol capsule 4 from external force damage.
[0021] Embodiment 2 of the present invention is an insulin pen needle. Based on Embodiment 1, the needle cover 3 and the needle housing 1 are threadedly connected.
[0022] The threaded structure allows the sterile sponge 31 soaked in disinfectant alcohol to rotate relative to the needle body 2 when the needle sleeve 3 and the needle housing 1 are separated, thereby further disinfecting the needle body 2 more thoroughly.
[0023] Embodiment 3 of the present invention is an insulin pen needle. Based on Embodiment 1 or 2, the needle sleeve 3 is in a truncated cone shape, and the placement cavity 6 is arranged at the top of the needle sleeve 3.
[0024] When squeezing the alcohol capsule 4, the needle sleeve 3 is placed upright, that is, the needle body 2 is at the lower end and the needle sleeve 3 is at the upper end. The disinfecting alcohol in the broken alcohol capsule 4, under the action of gravity, penetrates the sterile sponge 31 at the bottom and can be completely absorbed by the sterile sponge 31, avoiding leakage of the disinfecting alcohol.
[0025] Embodiment 4 of the present invention is an insulin pen needle. Based on any one of embodiments 1 to 3, a retaining ring 33 is further provided at the bottom of the needle cover 3.
[0026] The retaining ring 33 can prevent the sterile sponge 31 in the needle sheath 3 from accidentally falling off when the needle sheath 3 is separated from the needle housing 1 .
[0027] Embodiment 5 of the utility model is an insulin pen needle. Based on any one of embodiments 1 to 4, a sealing film 7 is provided at the bottom of the needle housing 1.
[0028] The sealing film 7 covers the bottom of the needle housing 1, which can effectively prevent air and pollutants from entering the interior of the needle housing 1, thereby ensuring that the insulin pen needle is in a sterile state before use.
[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
