Description

Technical Field

[0001] This utility model relates to the field of needle tip anti-puncture technology, specifically to an anti-puncture device for insulin pen needles. Background Technology

[0002] The insulin pen needle anti-puncture device is an auxiliary device specifically designed for the safe disposal and storage of used insulin pen needles.

[0003] A search of Chinese patent CN220025790U reveals a needle-prevention device for insulin pens, comprising a needle-prevention box and a needle collection box. The needle collection box is located below the needle-prevention box, and has an open top on its upper side. A first channel runs vertically through the center of the upper side of the needle-prevention box, and two sets of identical, radially symmetrical clamping devices are located inside the needle-prevention box below the first channel. This patent has a simple structure and is easy to use. By using the needle-prevention box and needle collection box, the needle-prevention box removes the insulin pen needle, and the needle collection box collects the needle, thus preventing accidental needle injury to the operator when removing the needle. Furthermore, the needle-prevention box removes and re-capsulates the inner needle of the insulin pen, preventing needle injuries to clinical nurses or patients during insulin injection.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. There is still a risk that the user will directly come into contact with the needle during the installation and removal of the needle. Moreover, the fixing and sealing mechanism of the needle after use is not reliable enough, which may cause the needle to fall off accidentally or puncture the container, causing secondary injury. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a needle-prevention device for insulin pens.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a needle anti-puncture device for insulin pens, including a housing, a support fixedly mounted on the housing, a rotating shell rotatably mounted between the housing and the support, and a blocking mechanism and a clamping mechanism.

[0008] The blocking mechanism is disposed on the housing, and the blocking mechanism includes two sets of first support components disposed on the housing, and a second support component is disposed on each set of first support components;

[0009] Multiple loading mechanisms are movably mounted on the rotating shell;

[0010] The clamping mechanism is mounted on the loading mechanism.

[0011] Furthermore, the outer casing has an opening.

[0012] Furthermore, the first support component includes a fixed shell that is fixedly mounted on the outer casing.

[0013] Furthermore, a first spring is connected to the inner wall of the fixed shell, and a movable block that is slidably connected to the end of the first spring is connected to the fixed shell.

[0014] Furthermore, the second support assembly includes a second spring connected to the inner wall of the movable block, and the end of the second spring is connected to a protrusion that is slidably connected to the movable block.

[0015] Furthermore, the loading mechanism includes an inner shell movably mounted on the rotating shell, a cover threaded onto the inner shell, and a needle body placed inside the inner shell.

[0016] Furthermore, the clamping mechanism includes two sets of third springs connected to the inner wall of the inner shell. The end of each set of third springs is connected to a rubber clip that abuts against the needle body. A button that is slidably connected to the inner shell is fixedly installed on the rubber clip.

[0017] The above-described solution of this utility model has at least the following beneficial effects:

[0018] In this invention, the inner shell and the cover work together to protect the sterile needle body. During use, rotating the rotating shell around the support pillar moves the inner shell to the corresponding opening position. Pressing the cover causes it to press against the protrusion and movable block through the inner shell, moving the protrusion inside the movable block and the movable block inside the fixed shell. This moves the inner shell and the cover out of the rotating shell. Opening the cover and pressing the button causes the rubber clips to press against the needle body, securing the insulin pen threads to the needle body. After use, moving the insulin pen moves the needle body between the two rubber clips, and pressing the button removes the needle body from the insulin pen. This eliminates the need to touch the needle body during use, improving the puncture prevention effect. Furthermore, after disposal, the third spring uses its elasticity to hold the needle body in place through the rubber clips, preventing accidental removal of the needle body even if accidentally opened, thus avoiding injury.

[0026] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0027] like Figures 1 to 5 As shown, an embodiment of this utility model provides a needle anti-puncture device for insulin pens, including a housing 1, a support column 2 fixedly installed on the housing 1, a rotating shell 3 rotatably installed between the housing 1 and the support column 2, and also includes a blocking mechanism and a clamping mechanism.

[0028] The blocking mechanism is provided on the outer shell 1. The blocking mechanism includes two sets of first support components provided on the outer shell 1. Each set of first support components is provided with a second support component. The outer shell 1 has an opening 4. The first support component includes a fixed shell 5 fixedly installed on the outer shell 1. A first spring 6 is connected to the inner wall of the fixed shell 5. The end of the first spring 6 is connected to a movable block 7 that is slidably connected to the fixed shell 5. The second support component includes a second spring 8 connected to the inner wall of the movable block 7. The end of the second spring 8 is connected to a protrusion 9 that is slidably connected to the movable block 7.

[0029] In use, by rotating the rotating shell 3, the rotating shell 3 rotates around the support column 2, causing the rotating shell 3 to move the inner shell 10 to the corresponding position of the opening 4. Pressing the cover 11 causes the cover 11 to press the protrusion 9 and the movable block 7 through the inner shell 10, causing the protrusion 9 to move into the inside of the movable block 7, and the movable block 7 to move into the inside of the fixed shell 5, causing the inner shell 10 and the cover 11 to move out of the inside of the rotating shell 3. At this time, the first spring 6 uses its own elastic force to drive the movable block 7 to move out of the inside of the fixed shell 5, and the second spring 8 uses its own elastic force to drive the protrusion 9 to move out of the inside of the movable block 7.

[0030] Figures 1 to 5 As shown, multiple loading mechanisms are movably mounted on the rotating shell 3. A clamping mechanism is set on the loading mechanism. The loading mechanism includes an inner shell 10 movably mounted on the rotating shell 3. A cover 11 is threaded onto the inner shell 10. A needle body 12 is placed inside the inner shell 10. The clamping mechanism includes two sets of third springs 13 connected to the inner wall of the inner shell 10. The end of each set of third springs 13 is connected to a rubber clip 14 that abuts against the needle body 12. A button 15 that is slidably connected to the inner shell 10 is fixedly mounted on the rubber clip 14.

[0031] The inner shell 10 and the cover 11 work together to protect the sterile needle body 12. By opening the cover 11 and pressing the button 15, the button 15 causes the rubber clips 14 to squeeze the needle body 12, which facilitates the fixing of the insulin pen threads to the needle body 12. After use, the needle body 12 is moved between the two rubber clips 14 by moving the insulin pen, and the button 15 is pressed to remove the needle body 12 from the insulin pen. Thus, the needle body 12 does not need to be touched during use, which improves the anti-puncture effect. After disposal, the third spring 13 uses its own elasticity to hold the needle body 12 through the rubber clips 14. Even if it is accidentally opened, the needle body 12 will not easily move out of the inner shell 10, avoiding accidental injury.

[0032] Working principle: During use, the user rotates the rotating shell 3, causing it to rotate around the support column 2. This causes the rotating shell 3 to move the inner shell 10 to the corresponding position of the opening 4. Pressing the cover 11 causes it to press against the protrusion 9 and the movable block 7 through the inner shell 10. This causes the protrusion 9 to move into the inside of the movable block 7, and the movable block 7 to move into the inside of the fixed shell 5. This causes the inner shell 10 and the cover 11 to move out of the inside of the rotating shell 3. By opening the cover 11 and pressing the button 15, the user can press the rubber clip 14 to press against the needle body 12, thus securing the insulin pen threads to the needle body 12. After use, the user moves the insulin pen to move the needle body 12 between the two rubber clips 14, presses the button 15, removes the needle body 12 from the insulin pen, tightens the cover 11 onto the inner shell 10, and discards it into the trash can.

[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
