Description

Technical Field

[0001] The present application relates to the field of medical devices, and in particular to an insulin needle removal device. Background Art

[0002] The insulin pen saves diabetic patients from the tedious process of drawing insulin from the insulin bottle with a syringe, and also avoids the embarrassment of patients injecting insulin in public places. More importantly, it makes insulin injection more convenient for patients with poor eyesight or even blindness.

[0003] Insulin pens are generally divided into two types. One is a reusable insulin pen. After the cartridge of this pen is used up, you can replace the cartridge and reuse it. This way you can use it for many years or even a lifetime. The other is a disposable insulin pen. After using it, you throw away the pen and the cartridge together and replace it with a new one.

[0004] With respect to the above-mentioned related technologies, the inventors believe that after use, the current reusable insulin pen requires the user to remove the used needle by hand. During the process of removing the needle, it is easy for the user to come into contact with the used needle, which may cause a risk of needlestick injury. Utility Model Content

[0005] In order to avoid direct contact with used needles and reduce the risk of needle stick injuries, the present application provides an insulin needle removal device.

[0006] The present application provides an insulin needle removal device that adopts the following technical solution:

[0007] An insulin needle removal device includes a removal portion and a handle for setting the removal portion. The bottom end surface of the removal portion is concavely provided with a removal groove that matches the front end of the insulin pen. A clamping assembly for clamping the insulin needle is provided in the removal groove.

[0008] By adopting the above technical solution, the support of the removal part is extended by the handle, so that a certain distance is created between the user and the insulin needle. The removal groove opened on the removal part covers the insulin needle inside, thereby further avoiding the user from contacting the used needle. The clamping assembly allows the user to operate the used needle and remove the needle from the insulin pen, which reduces the user's direct contact with the needle during the removal of the insulin pen and effectively avoids the risk of needlestick injuries.

[0009] Optionally, a needle-accommodating groove is provided on the top wall of the removal groove, and the bottom of the needle-accommodating groove is connected to the top of the removal groove.

[0010] By adopting the above technical solution, the needle-receiving groove at the top of the removal groove can specifically accommodate the inserted part of the needle when the insulin pen is inserted into the removal groove, thereby protecting the needle during the needle removal process, reducing the breakage of the tiny needle, protecting the integrity of the removed needle, and avoiding secondary needle stick injuries.

[0011] Optionally, the clamping assembly includes a plurality of spring pieces, which are arranged on the side walls of the removal groove to clamp the insulin needle.

[0012] By adopting the above technical solution, when the needle enters the interior of the removal part, the needle is subjected to the elastic force of the spring sheet, so that the connection between the needle and the removal part is more stable. When the needle is screwed or pushed out, the needle can move synchronously with the removal part, reducing the risk of the needle falling during removal and avoiding contact between the user and the needle.

[0013] Optionally, a plurality of anti-slip stripes are provided on the clamping surface of the elastic piece.

[0014] By adopting the above technical solution, the friction between the spring piece and the needle is increased by the anti-slip strip, thereby increasing the clamping effect of the spring piece on the needle, further reducing the risk of the needle falling during removal.

[0015] Optionally, a connecting sleeve is provided on the outside of the removal part, the removal part is rotatably provided in the connecting sleeve, and a driving member is provided on the connecting sleeve to drive the removal part to rotate.

[0016] By adopting the above technical solution, the removal device can be automatically rotated through the connecting sleeve and the driving member to automatically remove the needle, thereby eliminating the need for the user to manually twist the needle, making it easier to remove the needle. At the same time, the driving member is used to drive the needle, making the needle removal process more stable and more efficient.

[0017] Optionally, the clamping assembly includes a plurality of spring clips, which are arranged on the side walls of the removal groove, and the side walls of the removal part are arranged to be hollow. One end of the spring clip is fixed to the side wall of the removal groove, and the other end of the spring clip extends into the interior of the removal part and is movably arranged. An electromagnetic part is arranged in the side wall of the removal part to drive the spring clip to clamp.

[0018] By adopting the above technical solution, when clamping the needle, the magnetism of the electromagnet can be used to increase the elastic potential energy of the spring, so that the spring has a greater clamping force, so that the needle can remain more stably inside the removal groove after disassembly, reducing the risk of the needle falling and further preventing the user from being injured by needle sticks.

[0019] Optionally, the removal portion is rotatably connected to the handle portion to change the direction of the axis of the removal portion.

[0020] By adopting the above technical solution, the removal part can be changed in the axial direction, so that the angle between the insulin pen and the handle can be changed during the removal of the needle, so that the user can hold the insulin pen and the removal device with one hand at the same time, making it more convenient for the user to remove the needle.

[0021] Optionally, the depth of the removal groove is less than the length of the insulin needle.

[0022] By adopting the above technical solution, the depth of the removal groove is smaller than the length of the insulin needle, so that after the needle is removed, the tail of the needle can be exposed outside the removal groove, thereby facilitating the user to remove the needle from the removal groove and reducing the situation where the needle is stuck in the removal groove.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The handle extends the support of the removal part, thereby creating a certain distance between the user and the insulin needle. The removal groove on the removal part covers the insulin needle inside, further preventing the user from coming into contact with the used needle. The clamping assembly allows the user to operate the used needle and remove it from the insulin pen, reducing direct contact with the needle during the removal process and effectively avoiding the risk of needlestick injuries.

[0025] 2. The needle is subjected to the elastic force of the shrapnel, making the connection between it and the removal part more stable. When the needle is screwed or pushed out, the needle can move synchronously with the removal part, reducing the risk of the needle falling during removal and avoiding contact between the user and the needle.

[0026] 3. The removal device can be automatically rotated to automatically remove the needle, eliminating the need for the user to manually twist the needle, making it easier to remove the needle. At the same time, the drive member is used to drive the needle, making the needle removal process more stable and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] Example 1:

[0035] The embodiment of the present application discloses an insulin needle removal device.

[0036] Reference Figure 1-Figure 2 The insulin needle removal device includes a removal portion 1 and a handle 2 for setting the removal portion 1. The handle 2 includes a rod-shaped gripping portion 21 and a U-shaped supporting portion 22, and one end of the gripping portion 21 is fixed together with the end of the supporting portion 22 facing away from its own opening. Two support rods 3 are fixedly provided on the side wall of the removal portion 1, and the two support rods 3 are respectively located on both sides of the axis of the removal portion 1 and the axes of the two support rods 3 are located on the same straight line and are arranged radially along the removal portion 1. The bottom end surface of the removal portion 1 is recessed with a removal groove 11 that matches the front end of the insulin pen, and a clamping component 4 for clamping the insulin needle is provided in the removal groove 11.

[0037] The handle 2 extends the support of the removal part 1, thereby creating a certain distance between the user and the insulin needle. The removal groove 11 provided on the removal part 1 covers the insulin needle inside, thereby further preventing the user from coming into contact with the used needle. The clamping assembly 4 allows the user to operate the used needle, thereby removing the needle from the insulin pen, reducing the user's direct contact with the needle during the removal of the insulin pen and effectively avoiding the risk of needlestick injuries.

[0038] The top wall of the removal slot 11 is provided with a needle-receiving slot 12, which extends upward from the top wall of the removal slot 11 and has a smaller diameter than the removal slot 11. The bottom of the needle-receiving slot 12 is connected to the top of the removal slot 11. The diameter of the needle-receiving slot 12 gradually decreases as it moves away from the removal slot 11, giving the needle-receiving slot 12 a tapered shape, thereby facilitating the needle's entry from the removal slot 11 into the needle-receiving slot 12.

[0039] The needle-receiving groove 12 at the top of the removal groove 11 can specifically accommodate the inserted part of the needle when the insulin pen is inserted into the removal groove 11, thereby protecting the needle during the needle removal process, reducing the breakage of the tiny needle, protecting the integrity of the removed needle, and avoiding secondary needle stick injuries.

[0040] The clamping assembly 4 includes a plurality of spring clips 41 arranged in an array along the circumference of the removal slot 11. These clips 41 are positioned on the sidewalls of the removal slot 11 to clamp the insulin needle. The ends of the spring clips 41 are fixedly connected to the sidewalls of the removal slot 11. The middle portion of the spring clips 41 is curved in an arched shape along the axis of the removal slot 11. When the needle is inserted into the removal slot 11, the needle pushes on the spring clips 41, causing them to deform, thereby clamping the needle using their elastic potential energy.

[0041] When the needle enters the removal part 1, the needle is subjected to the elastic force of the spring piece 41, so that the connection between the needle and the removal part 1 is more stable. When the needle is screwed or pushed out, the needle can move synchronously with the removal part 1, reducing the risk of the needle falling during removal and avoiding contact between the user and the needle.

[0042] The clamping surface of the spring piece 41 is also provided with a plurality of anti-slip stripes 411. It should be noted that the extension direction of the anti-slip stripes 411 is perpendicular to the direction of needle insertion, so that the spring piece 41 has a better clamping effect on the needle.

[0043] The anti-slip stripes 411 increase the friction between the spring piece 41 and the needle, thereby increasing the clamping effect of the removal part 1 on the needle, further reducing the risk of the needle falling during the removal process.

[0044] The depth of the removal groove 11 is less than the length of the insulin needle.

[0045] The depth of the removal groove 11 is less than the length of the insulin needle, so that after the needle is removed, the tail of the needle can be exposed outside the removal groove 11, thereby facilitating the user to remove the needle from the removal groove 11 and reducing the situation where the needle is stuck in the removal groove 11.

[0046] Example 2:

[0047] The embodiment of the present application provides an insulin needle removal device. The difference between the second embodiment and the first embodiment is that: Figure 3-Figure 4A connecting sleeve 13 is disposed on the exterior of the removal portion 1. The connecting sleeve 13 is coaxially arranged with the removal portion 1 and rotatably disposed within the connecting sleeve 13. A driving member 14 is disposed on the connecting sleeve 13 to drive the removal portion 1 in rotation. The driving member 14 can be a motor. The housing of the driving member 14 is fixedly mounted on the exterior of the connecting sleeve 13. The output shaft of the driving member 14 extends through the top wall of the connecting sleeve 13 and is coaxially fixedly connected to the removal portion 1. When the driving member 14 is activated, the output shaft of the driving member 14 drives the removal portion 1 to rotate, thereby enabling the removal portion 1 to screw the needle.

[0048] By connecting the sleeve 13 and the driving member 14, the removal device can be automatically rotated to automatically remove the needle, eliminating the need for the user to manually twist the needle, making it easier to remove the needle. At the same time, the driving member 14 is used to drive the needle removal process, making it more stable and efficient.

[0049] The clamping assembly 4 includes a plurality of spring clips 41, which are arranged on the side wall of the removal groove 11. The side wall of the removal part 1 is set to be hollow. One end of the spring clip 41 is fixed to the side wall of the removal groove 11, and the other end of the spring clip 41 extends into the interior of the removal part 1 and is movably set. An electromagnetic part 42 is set in the side wall of the removal part 1 to drive the spring clip 41 to clamp. It should be noted that the electromagnetic part 42 can be but is not limited to an electromagnet.

[0050] When clamping the needle, the magnetism of the electromagnet can be used to increase the elastic potential energy of the spring piece 41, so that the spring piece 41 has a greater clamping force, so that the needle can remain more stably inside the removal groove 11 after disassembly, reducing the risk of the needle falling and further preventing the user from being injured by needle sticks.

[0051] One end of the support rod 3 is fixedly connected to the connecting sleeve 13, and the other end of the support rod 3 passes through the support part 22 and is rotatably connected to the support part 22, so that the removal part 1 is rotatably connected to the handle 2 to change the direction of the axis of the removal part 1.

[0052] The removal portion 1 can change the axial direction, so that the angle between the insulin pen and the handle 2 can be changed during the removal of the needle, so that the user can hold the insulin pen and the removal device with one hand at the same time, making it more convenient for the user to remove the needle.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
