[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides an insulin needle disassembly device, comprising an insulin needle, a sleeve tube 2 for sleeve connection with the insulin needle, and a support base 3. The insulin needle is an insulin needle that can be placed with the front end of an insulin pen in clinical practice. The insulin needle consists of a needle seat 1 and a needle 11. The inner side wall of the needle seat 1 is provided with a thread that can be threadedly connected with the thread groove of the front end of the insulin pen, and the outer side wall of the needle seat 1 is provided with a concave groove that can be plugged with the convex groove of the inner side wall of the outer needle cap. The needle 11 is arranged on the needle seat 1, and the sleeve tube 2 is an annular structure. The inner diameter of the sleeve tube 2 is adapted to the outer diameter of the needle seat 1 on the insulin needle. The inner side wall of the sleeve tube 2 is provided with a plurality of protrusions 21 that can be plugged with the concave groove of the outer side wall of the needle seat 1, and the bottoms of the plurality of protrusions 21 are all fixedly connected to the inner side wall of the sleeve tube 2.

[0026] The support base 3 is arranged below the sleeve tube 2. The support base 3 is in the shape of a truncated cone. A groove 31 having the same inner diameter as the sleeve tube 2 is arranged on the support base 3. The edge of the groove 31 on the support base 3 is fixedly connected with the bottom tube opening of the sleeve tube 2. The length of the groove 31 on the support base 3 and the sleeve tube 2 with an annular structure after combination is adapted to the length of the needle seat 1 and the needle 11 in the insulin needle. A traceless adhesive 32 is arranged at the bottom of the support base 3. The sleeve tube 2 and the support base 3 are both made of lightweight medical plastic material.

[0027] In clinical operation, the support base 3 of the device can be placed downward first, and then the bottom of the support base 3 can be pressed against the folding table on the patient's bed or the bedside table next to the bed, so that the traceless adhesive 32 at the bottom of the support base 3 can be adhered to the folding table or the bedside table next to the bed, and the support base 3 together with the sleeve 2 can be fixed, so as to replace the hands of the nursing staff and the patient to hold the device;

[0028] Then, the needle 11 end of the insulin injection pen can be directed toward the sleeve tube 2 and inserted into the sleeve tube 2. During this operation, since the bottom of the support base 3 is provided with a traceless adhesive 32, the support base 3 and the sleeve tube 2 can be connected to the folding table board on the bed or the bedside table beside the bed, and the nursing staff and the patient do not need to control the support base 3 and the sleeve tube 2 by hand to maintain stability. When the needle seat 1 on the insulin injection needle 11 is connected to the top edge of the sleeve tube 2, the insulin injection pen can be slightly rotated so that the needle The concave grooves on the outer wall of the seat 1 can form an interlaced and pluggable position with the multiple protrusions 21 on the inner wall of the sleeve tube 2, and then the insulin injection pen can continue to be inserted into the sleeve tube 2 until the multiple protrusions 21 on the inner wall of the sleeve tube 2 form a stop state with the bottom area of ​​the concave grooves on the outer wall of the needle seat 1 (that is, the needle seat 1 is in the sleeve tube 2), and then the insulin injection pen is rotated (the rotation direction is the direction in which the front end thread groove of the insulin injection pen and the thread of the needle seat 1 are separated), and the insulin injection pen can be slightly pressed toward the sleeve tube 2 during the rotation process;

[0029] As the insulin injection pen rotates, the multiple protrusions 21 on the inner wall of the sleeve tube 2 will restrict the rotation of the needle seat 1 when they are plugged into the grooves on the outer wall of the needle seat 1, and the front end of the insulin injection pen will gradually separate from the threaded connection state of the needle seat 1, thereby realizing the disassembly operation of the needle 11 on the insulin injection pen. After the needle 11 is removed from the insulin injection pen, the sleeve tube 2 and the supporting base 3 retaining the insulin needle and the needle seat 1 can be removed from the folding table on the patient's bed or the bedside table next to the bed, thereby completing the disassembly operation of the front end needle of the insulin injection pen.

[0030] Furthermore, a guide component 4 is provided at the top of the sleeve tube 2, the bottom end of the guide component 4 is adapted to the outer diameter of the sleeve tube 2, the upper end of the guide component 4 expands and extends to the outside of itself, so that the guide component 4 forms a truncated cone shape, the interior of the guide component 4 is arranged in a cavity shape, and the cavity portion passes through the bottom end of the guide component 4 and forms an opening with the same inner diameter as the sleeve tube 2, the bottom end of the guide component 4 is fixedly connected to the top edge of the sleeve tube 2, and the material of the guide component 4 is consistent with the sleeve tube 2 and the support base 3. The material is the same. When the front end needle 11 of the insulin injection pen is inserted into the sleeve tube 2, the setting of the upper end of the guide component 4 expanding and extending toward the outside of itself is that the guide component 4 forms a trumpet-like structure to expand the diameter of the pluggable end on the guide component 4, so that the front end needle 11 of the insulin injection pen and the needle seat 1 can be gradually transferred along the inner wall of the guide component 4 to the top edge of the sleeve tube 2 when they contact the inner wall of the guide component 4, so that the insertion operation of the front end needle 11 of the insulin injection pen and the sleeve tube 2 can be more convenient.

[0031] Furthermore, the surfaces of the multiple protrusions 21 on the inner wall of the sleeve tube 2 and the inner wall areas of the sleeve tube 2 between the multiple protrusions 21 are provided with an adhesive layer. When the threaded groove at the front end of the insulin injection pen is in a state of being in a state of being adjacent to separation from the threaded connection with the thread of the outer wall of the needle seat 1, the insulin injection pen needs to be slightly pulled during the rotation process to separate the needle seat 1 from it. By providing the adhesive layer on the surfaces of the multiple protrusions 21 on the inner wall of the sleeve tube 2 and the inner wall areas of the sleeve tube 2 between the multiple protrusions 21, the groove area on the outer wall of the needle seat 1 can be adhered to the multiple protrusions 21 on the inner wall of the sleeve tube 2, and when the insulin injection pen is pulled, a certain restriction effect is applied to the needle seat 1, thereby facilitating the removal of the front end of the insulin injection pen from the needle seat 1.

[0032] Furthermore, a silicone gasket 5 is horizontally placed inside the sleeve tube 2, the silicone gasket 5 is located adjacent to the bottom of the sleeve tube 2, the edge of the silicone gasket 5 is fixedly connected to the inner wall of the sleeve tube 2, and a water-absorbing cotton 6 is arranged in the groove 31 on the support base 3;

[0033] When the front end needle 11 of the insulin injection pen extends into the sleeve tube 2, the front end needle 11 can penetrate along the top of the silicone gasket 5 and pass out from the bottom of the silicone gasket 5, so that the silicone gasket 5 forms a filling between the needle 11 and the inner wall side of the sleeve tube 2, so as to avoid insulin overflowing from the sleeve tube 2 when the sleeve tube 2 and the support base 3 are removed. The absorbent cotton 6 arranged in the groove 31 of the support base 3 can be penetrated by the needle 11 passing through the bottom of the silicone gasket 5, so as to absorb the insulin seeping from the needle 11.

[0034] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
