Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an insulin pen needle removal device. Background Technology

[0002] An insulin pen is an advanced insulin injection device that is widely used in the treatment of diabetes. An insulin pen typically consists of three parts: the pen body, the cartridge, and the needle.

[0003] In the existing technology, when the needle needs to be removed and properly disposed of after using an insulin pen, the current method is mostly to manually unscrew the needle. Since the needle is thin and sharp, if the operator is not careful, the needle tip can easily prick the operator, which poses a certain safety hazard. Therefore, an insulin pen needle removal device is needed. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an insulin pen needle remover. With the setting of the needle remover, positioning block and positioning groove, when it is necessary to remove the needle, the insert block is inserted into the positioning groove, and then the needle remover is rotated to unscrew the needle from the insulin pen. This eliminates the need for the operator to manually twist the needle, reducing the risk of the operator being pricked. Furthermore, with the setting of the squeezing rod, after the needle is removed, pressing the squeezing rod will push the needle out of the needle remover, which is simple and quick.

[0005] This utility model also provides an insulin pen needle extractor, comprising an insulin pen and a needle extractor. A needle is threaded onto the insulin pen, and an insert block is fixedly connected to the outer surface of the needle. A positioning cylinder is fixedly connected to the needle extractor, and two limiting blocks are fixedly connected to the inner surface of the positioning cylinder. A slider is slidably connected to the inner surface of each of the two limiting blocks, and the same squeezing rod is fixedly connected to the two sliders. A positioning block is fixedly connected to the inner surface of the positioning cylinder, and a positioning groove is formed on the positioning block.

[0006] According to the insulin pen needle extractor, the squeezing rod has a storage groove, and the outer surface of the squeezing rod is slidably connected to the needle extractor. The storage groove can store and protect the needle tip, so that the needle can be easily fixed on the needle extractor.

[0007] According to the insulin pen needle removal device, a protective ring is fixedly connected to the needle removal device, and a second fixing block is fixedly connected to the outer surface of the protective ring. The protective ring can protect structures such as the positioning cylinder.

[0008] According to the insulin pen needle removal device, the side surface of the second fixing block is fixedly connected to the needle removal device, and there are multiple second fixing blocks arranged in a circular array. Under the action of the second fixing blocks, the stability of the protective ring can be improved.

[0009] According to the insulin pen needle dispensing device, a first fixing block is fixedly connected to the inner surface of the protective ring, and the side surface of the first fixing block is fixedly connected to the positioning cylinder. Under the action of the first fixing block, the stability of the positioning cylinder can be improved.

[0010] According to the insulin pen needle dispensing device, a limiting groove is formed on the limiting block, and the outer surface of the slider is slidably connected to the limiting groove to limit the movement direction and movement distance of the slider.

[0011] According to the insulin pen needle dispensing device, the number of positioning blocks is multiple and distributed in a circular array, and the number of positioning slots is multiple and distributed in a circular array.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-5 This utility model discloses an insulin pen needle extraction device, comprising an insulin pen 1 and a needle extraction device 2. A needle 3 is threaded onto the insulin pen 1, and an insertion block 4 is fixedly connected to the outer surface of the needle 3. A positioning cylinder 5 is fixedly connected to the needle extraction device 2, and two limiting blocks 6 are fixedly connected to the inner surface of the positioning cylinder 5. Sliding sliders 7 are slidably connected to the inner surfaces of both limiting blocks 6, and a single extrusion rod 8 is fixedly connected to both sliding sliders 7. A positioning block 9 is fixedly connected to the inner surface of the positioning cylinder 5, and a positioning groove 10 is formed on the positioning block 9. A receiving groove 11 is formed on the extrusion rod 8. The outer surface of the extrusion rod 8 is connected to the needle extraction device 2. The device is slidably connected to a protective ring 12, and a second fixing block 14 is fixedly connected to the outer surface of the protective ring 12. The side surface of the second fixing block 14 is fixedly connected to the needle extractor 2. There are multiple second fixing blocks 14 arranged in a ring array. A first fixing block 13 is fixedly connected to the inner surface of the protective ring 12. The side surface of the first fixing block 13 is fixedly connected to the positioning cylinder 5. There are multiple positioning blocks 9 arranged in a ring array. There are multiple positioning grooves 10 arranged in a ring array. A limiting groove 15 is opened on the limiting block 6. The outer surface of the slider 7 is slidably connected to the limiting groove 15.

[0023] Working principle: When the needle 3 needs to be removed from the insulin pen 1, the insert 4 on the needle 3 is inserted into the positioning groove 10 on the positioning block 9. During insertion, the needle 3 gradually squeezes the squeezing rod 8, causing the squeezing rod 8 to move with the storage groove 11. The moving squeezing rod 8 also drives the limiting block 6 to move within the limiting groove 15 on the slider 7, preventing the squeezing rod 8 from wobbling during movement. After the insert 4 is fully inserted into the positioning groove 10, the needle extractor 2 is rotated, causing the rotating needle extractor 2 to move the structure on the needle extractor 2 and the needle. The head 3 and the insert block 4 are rotated so that the needle 3 can be unscrewed from the insulin pen 1. After the insert block 4 is inserted into the positioning groove 10, the needle 3 can be fixed. Then the device is moved to the position of the medical waste collection box or other processing device. Press the squeezing rod 8 to move the squeezing rod 8 and the limiting block 6. During the movement, the squeezing rod 8 will push the needle 3 to move, so that the moving needle 3 will drive the insert block 4 to move. When the moving insert block 4 is disengaged from the positioning groove 10, the needle 3 will be disengaged from the needle extractor 2 and fall into the processing device.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
