Detailed Implementation

[0040] It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. In the following description, suffixes such as "module," "part," or "unit" used to denote elements are used solely for illustrative purposes and have no inherent meaning. Therefore, "module," "part," or "unit" may be used interchangeably.

[0041] This utility model provides an insulin needle disassembly device, comprising: a handle 1; a cylinder 4 having a first cylinder sliding hole and a second cylinder sliding hole at its upper end, and an open structure at its lower end; a clamping assembly disposed within the cylinder 4 for clamping the needle base of the insulin needle; and a driving assembly disposed within the cylinder 4 and connected to the clamping assembly for driving the clamping assembly to move by changing the height between the handle 1 and the cylinder 4, thereby clamping and releasing the needle base of the insulin needle.

[0042] Furthermore, the handle 1 is in the shape of a straight line.

[0043] Furthermore, the clamping assembly includes a clamping bracket 5 and a clamping claw 6; wherein, the clamping claw 6 includes a first clamping claw and a second clamping claw; the clamping bracket 5 includes: a first clamping bracket, one end of which is disposed on the inner wall of the cylinder 4, and the other end of which is provided with a first clamping claw; a second clamping bracket, one end of which is disposed on the inner wall of the cylinder 4, and the other end of which is provided with a second clamping claw; wherein, the distance between the first clamping claw and the second clamping claw is adjustable to clamp and release the needle base of the insulin needle.

[0044] Furthermore, such as Figure 1 and Figure 2 As shown, the support bracket 5 includes a first support bracket and a second support bracket; the cylindrical sliding hole 3 includes a first sliding hole and a second sliding hole; wherein, the first sliding hole and the second sliding hole are elongated sliding holes, and the first sliding hole ( Figure 1 and Figure 2 The right side of the middle left) and the second sliding hole ( Figure 1 and Figure 2 The left side of the right side of the device is provided with a retainer to fix the connection position of the first clamping bracket and the first support rod in the first sliding hole and to fix the connection position of the second clamping bracket and the second support rod in the second sliding hole, so that the clamping assembly clamps the needle base of the insulin needle. Then, by rotating the insulin pen and / or rotating the cylinder, the needle base with the needle and the insulin pen are separated.

[0045] The driving assembly includes: a cross bracket 7 disposed between the handle 1 and the cylinder 4, consisting of a first support rod and a second support rod, and fixed at an intersection; wherein one end of the first clamping bracket and the second clamping bracket are disposed at different positions on the cylinder 4, and the first clamping bracket and the second clamping bracket are cross-connected; one end of the first clamping bracket is connected to the first support rod at the first sliding hole position; one end of the second clamping bracket is connected to the second support rod at the second sliding hole position, so that the first clamping bracket and the first support rod can move left and right simultaneously within the first sliding hole, and the second clamping bracket and the second support rod can move left and right simultaneously within the second sliding hole.

[0046] like Figure 1 and Figure 2 As shown, when the cross bracket 7 is stretched, the first clamping bracket and the first support rod simultaneously move to the right within the first sliding hole, while the second clamping bracket and the second support rod simultaneously move to the left within the second sliding hole. This collectively drives the clamping assembly to clamp the needle base of the insulin needle. Then, by rotating the insulin pen and / or rotating the cylinder, the needle base with the needle is separated from the insulin pen. After the needle base with the needle is separated from the insulin pen, it needs to be discarded. At this time, the user needs to compress the cross bracket 7. When the cross bracket 7 is compressed, the first clamping bracket and the first support rod simultaneously move to the left within the first sliding hole, while the second clamping bracket and the second support rod simultaneously move to the right within the second sliding hole. This collectively drives the clamping assembly to loosen the needle base of the insulin needle, thus allowing the needle base with the needle to be discarded.

[0047] Furthermore, such as Figure 3 and Figure 4 As shown, the drive block 9 includes a first drive block and a second drive block; the drive rod 11 includes a first drive rod and a second drive rod; the small spring 12 includes a first small spring disposed below the first drive block and located between the cylinder 4 and the first drive rod, and a second small spring disposed below the second drive block and located between the cylinder 4 and the second drive rod; furthermore, one end of the first small spring is fixedly connected to the inner wall on the left side of the cylinder 4, and the other end is fixedly connected to the first drive rod; one end of the second small spring is fixedly connected to the inner wall on the right side of the cylinder 4, and the other end is fixedly connected to the second drive rod.

[0048] like Figure 3 and Figure 4As shown, the driving assembly includes: a spring 8 disposed between the handle 1 and the cylinder 4; a first driving block (left side of the figure) disposed between the first clamping bracket (left side of the figure) and the inner side of the cylinder 4; a second driving block (right side of the figure) disposed between the second clamping bracket (right side of the figure) and the inner side of the cylinder 4; a first driving rod, one end of which passes through the sliding hole of the first cylinder and is fixed to the handle 1, and the other end of which is fixed to the first driving block; a second driving rod, one end of which passes through the sliding hole of the second cylinder and is fixed to the handle 1, and the other end of which is fixed to the second driving block; wherein, one end of the first clamping bracket and the second clamping bracket are disposed at the same position on the inner wall of the cylinder 4.

[0049] like Figure 3 and Figure 4 As shown, when the spring 8 is compressed, the first drive rod pushes the first drive block to move downward along the cylinder track inside the cylinder 4, and the first small spring is stretched; at the same time, the second drive rod pushes the second drive block to move downward along the cylinder track inside the cylinder 4, and the second small spring is stretched, together driving the clamping assembly to move, so as to clamp the needle base of the insulin needle, and then by rotating the insulin pen and / or rotating the cylinder, the needle base with the needle and the insulin pen are separated. After the needle base with the needle tip is separated from the insulin pen, the needle base with the needle tip needs to be discarded. At this time, the user needs to reset the spring. When the spring 8 is reset, the first drive rod pushes the first drive block to move upward along the cylinder track inside the cylinder 4, and the first small spring is reset. At the same time, the second drive rod pushes the second drive block to move upward along the cylinder track inside the cylinder 4, and the second small spring is also reset. Together, they drive the clamping assembly to move, so as to loosen the needle base of the insulin needle, that is, to discard the needle base with the needle tip.

[0050] Furthermore, such as Figure 5 and Figure 6 As shown, the clamping claw 6 is an arc-shaped clamping claw or a straight rod-shaped clamping claw. Clamping structures 61 are respectively provided on the opposite sidewalls of the clamping claw 6 to facilitate clamping the needle base of the insulin needle; the clamping structures are corrugated patterns or several protrusions provided on the sidewalls of the clamping claw 6.

[0051] In one embodiment of this utility model, the opening structure at the lower end of the cylinder 4 is a trumpet-shaped opening. It should be noted that by using a larger opening, it is beneficial to increase the needle insertion area, which not only improves the alignment efficiency, but also avoids needle puncture injuries to medical staff caused by an excessively small needle insertion area.

[0052] Although the present invention has been described in detail above, it is not limited thereto. Those skilled in the art can make various modifications based on the principles of the present invention. Therefore, all modifications made in accordance with the principles of the present invention should be understood as falling within the protection scope of the present invention.
