Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and specifically relates to an automatic insulin needle disassembly device and injection tray. Background Technology

[0002] Insulin pens and insulin needles are common medical supplies used in clinical practice. Statistics show that the number of patients in my country requiring insulin injections to control blood sugar is increasing year by year. Consequently, the number of insulin pens and needles used in major hospitals is also increasing annually. However, there is currently no convenient and readily available insulin needle remover in clinical practice. Whether in the hospital or after discharge, there is a certain risk of needlestick injury every time the insulin needle is removed after an injection. After an insulin pen injection, the needle needs to be removed as required. Because the needle is short, thin, and sharp, the current conventional method is to cover the needle with an outer needle cap, clamp the outer needle cap with your hand or hemostats, and rotate the outer needle cap to rotate the needle and remove it. However, this operation is prone to situations where the outer needle cap is removed but the needle is not successfully removed, resulting in needlestick injury and increasing the risk of occupational exposure. Patients requiring insulin injections outside the hospital also face this risk. Furthermore, a separate sharps container is needed to collect used needles, which is inefficient for needle removal.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1-6 As shown, this automatic insulin needle disassembly device includes a mounting base 1 and a sharps container 2. The mounting base 1 is provided with a first storage hole 3, a second storage hole 4, and a needle disassembly device 5. The first storage hole 3 and the second storage hole 4 are used to store medical devices. The needle disassembly device 5 includes a limiting device 6 and a rotating device 7. The limiting device 6 is used to restrict the position of the insulin needle, and the rotating device 7 is used to rotate and disassemble the insulin needle. The sharps container 2 is located below the limiting device 6.

[0027] To elaborate further, the mounting base 1 is provided with a receiving cavity 8 for mounting the needle removal device 5 and the sharps container 2. This arrangement is used to hide the sharps container 2 and the needle removal device 5 inside, preventing the needle from flying out during removal.

[0028] To elaborate further, the mounting base 1 is provided with a through hole 9, which connects to the receiving cavity 8. The rotating device 7 includes a drive motor 11, a first gear 12 mounted on the output shaft of the drive motor 11, and a support cylinder 14. The support cylinder 14 is rotatably connected to the through hole 9 and is used to support the limiting device 6. A second gear 13 is provided on the outer surface of the support cylinder 14, which meshes with the first gear 12. An extension plate is provided on the top surface of the support cylinder 14, and a sliding groove is provided on the side wall of the through hole 9. The extension plate is slidably connected to the sliding groove. The drive motor 11 drives the first gear 12 to rotate, thereby driving the second gear 13 to rotate, causing the support cylinder 14 to rotate. This arrangement is used to drive the limiting device 6 to rotate after the limiting device 6 limits the needle, thereby unscrewing the needle.

[0029] To elaborate further, the limiting device 6 includes multiple limiting components 15, which are evenly arranged along the circumference of the inner wall of the supporting cylinder 14. Each limiting component 15 includes an L-shaped limiting block 23, a rotating shaft 24, and a torsion spring. The rotating shaft 24 is fixedly connected to the inner wall of the supporting cylinder 14, and the L-shaped limiting block 23 is rotatably connected to the rotating shaft 24 via the torsion spring. The L-shaped limiting block 23 includes a sliding part 25 and a friction part 26. In this embodiment, four limiting components 15 are provided. In the initial state, the four sliding parts 25 are at their closest distance, and the four friction parts 26 are at their farthest distance. At this time, the distance between the sliding parts 25 is less than the diameter of the needle, and the distance between the friction parts 26 is greater than the diameter of the needle. When a medical staff member inserts an insulin needle, the insulin... The needle first touches the sliding part 25, which then spreads the four sliding parts 25 apart, gradually increasing the distance between them. This causes the friction parts 26 below to move closer together. Due to the design of the sliding parts 25, the insulin needle can continue downward until the needle touches the friction parts 26. At this point, the distance between the four friction parts 26 is the shortest, and the sliding parts 25 touch the syringe. The rotating device 7 is turned on. Due to the design of the sliding parts 25, when the supporting cylinder 14 rotates, the sliding parts 25 and the syringe are in a sliding connection. The friction parts 26 drive the needle to rotate counterclockwise around the syringe. The needle is then unscrewed, and the medical staff removes the syringe. Under the action of the torsion spring, the L-shaped limiting block 23 returns to its initial position, and the needle falls into the sharps container 2, completing the disassembly of the needle.

[0030] To elaborate further, the end of the sliding part 25 is provided with a mounting groove 27, and a ball bearing 28 is provided in the mounting groove 27. The ball bearing 28 rolls in the mounting groove 27. The mounting groove 27 is used to limit the ball bearing 28 from falling out. This arrangement is used to reduce the friction between the sliding part 25 and the insulin needle.

[0031] To elaborate further, the end of the friction part 26 is provided with a friction layer 29, which is provided to increase the friction between the friction layer 29 and the insulin needle, ensuring that the needle can be driven to rotate counterclockwise.

[0032] To elaborate further, the receiving cavity 8 is provided with an opening 16, and an L-shaped sealing plate 17 is detachably connected to the opening 16. The L-shaped sealing plate 17 is provided with a fixing groove 18 for fixing the sharps container 2. An extension plate 19 is provided at the opening of the fixing groove 18. This arrangement is to facilitate medical staff to replace the sharps container 2. At the same time, the fixing groove 18 and the extension plate 19 have the effect of fixing the sharps container 2, preventing the sharps container 2 from tilting and falling when it is taken out, thus preventing medical hazards.

[0033] To elaborate further, the mounting base 1 is equipped with a button, which is used to control the operation of the drive motor 11. This device uses a battery to power the drive motor 11, and the button is also a switch, making it convenient for medical staff to operate.

[0034] To elaborate further, the first storage hole 3 has five holes, and the second storage hole 4 has four holes. This setting allows medical staff to prepare the necessary materials for each injection into a patient.

[0035] like Figure 7-8 As shown, this utility model also provides an injection tray for using an automatic insulin needle disassembly device, including a treatment tray 20 and an automatic insulin needle disassembly device as described above. The side wall of the treatment tray 20 is provided with a slot 22, and the mounting base 1 is provided with a buckle 21. The mounting base 1 is detachably connected to the slot 22 through the buckle 21, so that the treatment tray 20 and the automatic insulin needle disassembly device are detachably set, which facilitates subsequent cleaning and disinfection. At the same time, the treatment tray 20 can also be used independently.
