Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to an insulin injection needle remover for a sharps box and a sharps box. Background Art

[0002] The insulin injection needle is threadedly connected to the insulin pen. The needle is disposable and needs to be removed and put into the sharps box after insulin injection. The hospital does not allow medical staff to directly hold the needle and rotate it to remove it, because the hand is close to the needle tip during operation, which can easily cause puncture injuries.

[0003] In order to avoid puncture wounds caused by disassembling insulin injection needles, some disassembly tools have emerged. A better way of disassembly is to directly set a disassembly tool on the sharps box so that the needle falls into the sharps box after being removed. Patent application number 202221082081.0 discloses an insulin needle disassembly sharps box. A disassembly sleeve is provided on the sharps box. The inner wall of the disassembly sleeve is provided with a groove for engaging with the anti-slip pattern of the insulin needle. When the insulin needle is disassembled, the anti-slip pattern of the insulin needle is engaged with the groove, and then the insulin needle can be removed by rotating the insulin pen. Although the disassembly sleeve of this patent can remove the needle, such as Figure 1 and Figure 2 As shown in the figure, the needle groove on the insulin injection needle is not a through groove. After the needle is removed, due to the rear structure of the needle groove ( Figure 1 The needle will come into contact with the protrusion of the removal sleeve at point a, so that the needle cannot be directly dropped into the sharps box. Other methods are needed to make the needle enter the sharps box, which is actually very inconvenient.

[0004] Patent application number 201620346396.X discloses a device for disassembling the needle tip of an insulin needle, which is applied for by the applicant of this application. The disassembly device has a telescopic sleeve and a pressure cover. By pressing the pressure cover, the telescopic sleeve can shrink and tighten the needle tip, and then the insulin pen can be removed by rotating it. Then, the pressure cover is loosened, and the telescopic sleeve rebounds without tightening the needle tip, and the needle tip can fall into the sharps box. The disassembly device solves the problem that the needle tip does not fall into the sharps box after being removed, but the pressure cover needs to be pressed all the time when the disassembly device is used, which is not convenient to use. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an insulin injection needle remover for a sharps box, which can remove an insulin injection needle and easily drop the needle into the sharps box.

[0006] The technical solution adopted to solve the above problems is: the insulin injection needle remover for the sharps box includes a panel, a sleeve, an operating structure and two disassembly structures; the panel is horizontally arranged, the sleeve is vertically arranged and connected to the panel, and the inner hole of the sleeve is the needle hole; the disassembly structure is arranged along the radial direction of the sleeve, and the two disassembly structures are arranged on both sides of the sleeve. The disassembly structure includes a disassembly structure guide sleeve, a disassembly rod and a disassembly structure spring. The disassembly rod includes a disassembly rod body and a disassembly piece located at the inner end of the disassembly rod body and vertically arranged. The outside of the disassembly rod body is inserted into the disassembly structure guide sleeve, the disassembly structure spring is arranged in the disassembly structure guide sleeve and pushes the disassembly rod inward so that the disassembly piece passes through the sleeve and extends into the needle hole. The disassembly rod body is provided with a disassembly rod hole, and the outer wall surface of the disassembly rod hole is a disassembly rod inclined surface; the operating structure includes a connecting plate and a driving plate, the driving plate is arranged one-to-one with the disassembly structure, the driving plate is vertically arranged and passes through the panel, and the driving plate moves downward to push the disassembly rod inclined surface outward so that the disassembly piece exits the needle hole, and the connecting plate is connected to the two driving plates.

[0007] Furthermore, the inner end of the disassembly rod body abuts against the sleeve, the length of the disassembly piece extending into the needle hole is greater than the depth of the needle groove of the insulin injection needle, and the upper end of the disassembly piece has an introduction slope.

[0008] Furthermore, the insulin injection needle remover for a sharps box includes a support structure, which is arranged in a one-to-one correspondence with the disassembly structure. The support structure is arranged along the radial direction of the sleeve and is located below the disassembly structure. The support structure includes a support structure guide sleeve, a support rod and a support structure spring. The outside of the support rod is inserted into the support structure guide sleeve. The support structure spring is arranged in the support structure guide sleeve and pushes the support rod inward so that the support rod passes through the sleeve and extends into the needle hole. The support rod is provided with a support rod hole, and the outer wall surface of the support rod hole is a support rod inclined surface. After the drive plate passes through the disassembly rod and moves further downward, it can push the support rod inclined surface outward to make the support rod withdraw from the needle hole.

[0009] Furthermore, the support rod is provided with a positioning flange, and the positioning flange abuts against the sleeve.

[0010] Furthermore, the operating structure includes a return spring, which is located between the connecting plate and the panel and connected to the two.

[0011] Furthermore, the lower end of the driving plate is provided with a driving inclined surface, and the inclination angles of the driving inclined surface, the disassembly rod inclined surface and the support rod inclined surface are all 45°.

[0012] Furthermore, the connecting plate is an annular plate coaxial with the sleeve.

[0013] Another technical problem to be solved by the utility model is to provide a sharps box into which an insulin injection needle can be removed and the needle can be dropped in easily.

[0014] The technical solution adopted to solve the above problem is: the sharps box includes a box body and a box cover, and the box cover is provided with the aforementioned insulin injection needle remover for the sharps box.

[0015] The beneficial effects of the utility model are: when the utility model is used, Figure 7 As shown, hold the insulin pen and insert the needle into the needle hole, and the disassembly piece is embedded in the needle groove on the needle. Then turn the insulin pen. Since the disassembly piece is embedded in the needle groove on the needle, the needle does not rotate, so the insulin pen can be separated from the needle and the needle can be removed; at this time, due to the structure behind the needle groove ( Figure 1 The needle cannot fall directly into the sharps box. Then the operating structure is pressed, the driving plate moves downward and pushes the inclined surface of the disassembly rod outward, so that the disassembly plate exits the needle hole. At this time, the disassembly plate no longer blocks the needle from falling, and the needle falls into the sharps box. It can be seen that the utility model can remove the insulin injection needle and can easily make the needle fall into the sharps box. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figures 3 to 6 As shown, the insulin injection needle remover for the sharps box includes a panel 1, a sleeve 2, an operating structure 5 and two disassembly structures 3; the panel 1 is horizontally arranged, the sleeve 2 is vertically arranged and connected to the panel 1, and the inner hole of the sleeve 2 is a needle hole 21; the disassembly structure 3 is arranged along the radial direction of the sleeve 2, and the two disassembly structures 3 are arranged on both sides of the sleeve 2, the disassembly structure 3 includes a disassembly structure guide sleeve 31, a disassembly rod 32 and a disassembly structure spring 33, the disassembly rod 32 includes a disassembly rod body 321 and a disassembly piece 322 located at the inner end of the disassembly rod body 321 and vertically arranged, and the outer part of the disassembly rod body 321 is inserted into the disassembly structure The guide sleeve 31 and the disassembly structure spring 33 are arranged in the disassembly structure guide sleeve 31 and push the disassembly rod 32 to make the disassembly piece 322 pass through the sleeve 2 and extend into the needle hole 21. The disassembly rod body 321 is provided with a disassembly rod hole 323, and the outer wall surface of the disassembly rod hole 323 is a disassembly rod inclined surface 324; the operating structure 5 includes a connecting plate 52 and a driving plate 51, and the driving plate 51 is arranged one by one with the disassembly structure 3. The driving plate 51 is vertically arranged and passes through the panel 1. The driving plate 51 moves downward to push the disassembly rod inclined surface 324 outward, so that the disassembly piece 322 withdraws from the needle hole 21, and the connecting plate 52 is connected to the two driving plates 51.

[0028] The insulin injection needle remover for sharps box is installed on the box cover of the sharps box for use, and the sharps box of the utility model is obtained, that is, the sharps box includes a box body and a box cover, and the box cover is provided with the aforementioned insulin injection needle remover for sharps box. Except for the provision of the insulin injection needle remover for sharps box, the other structures of the sharps box are the same as the prior art. The size of the needle hole 21 should match the outer diameter of the needle 6. The groove on the sleeve 2 through the disassembly sheet 322 should cooperate with the disassembly sheet 322 to prevent the disassembly sheet 322 from swinging horizontally.

[0029] When the utility model is used, Figure 7As shown, the insulin pen is held and the needle 6 is inserted into the needle hole 21, and the disassembly piece 322 is embedded in the needle groove 61 on the needle 6. Then the insulin pen is rotated, and since the disassembly piece 322 is embedded in the needle groove 61 on the needle, the needle 6 does not rotate, so the insulin pen and the needle 6 can be separated and the needle 6 can be removed; at this time, due to the rear structure of the needle groove 61 ( Figure 1 The needle 6 cannot fall directly into the sharps box. Then the operating structure 5 is pressed, the driving plate 51 moves downward and pushes the disassembly rod inclined surface 324 outward, so that the disassembly plate 322 withdraws from the needle hole. At this time, the disassembly plate 322 no longer blocks the needle 6 from falling, and the needle 6 falls into the sharps box.

[0030] The needle groove 61 is a shallow groove, and the disassembly piece 322 is preferably extended into the needle groove 61 as much as possible, so as to more effectively prevent the needle 6 from rotating. To this end, the utility model preferably has the inner end of the disassembly rod body 321 abut against the sleeve 2, the length of the disassembly piece 322 extending into the needle hole 21 is greater than the depth of the needle groove 61 of the insulin injection needle, and the upper end of the disassembly piece 322 has an introduction slope 325.

[0031] So Figure 8 As shown, when the needle 6 is inserted, the lower end of the needle 6 first abuts against the introduction slope 325. The needle 6 is pressed down slightly to make the disassembly rod 32 retreat, but the supporting force of the disassembly structure spring 33 still makes the disassembly piece 322 abut against the bottom of the needle groove 61. In this way, the disassembly piece 322 is inserted into the needle groove 61 as much as possible, which is conducive to the removal of the needle 6.

[0032] Although the above method is conducive to removing the needle 6, it may also cause the needle 6 to be removed too much, that is, Fig. 9 In the state, the disassembly sheet 322 abuts against the top of the needle groove 61, and enters the needle groove 61. In order to avoid this situation, the following configuration can be further provided: including a support structure 4, the support structure 4 is arranged one-to-one with the disassembly structure 3, the support structure 4 is arranged along the radial direction of the sleeve 2 and is located below the disassembly structure 3, the support structure 4 includes a support structure guide sleeve 41, a support rod 42 and a support structure spring 43, the outside of the support rod 42 is inserted into the support structure guide sleeve 41, the support structure spring 43 is arranged in the support structure guide sleeve 41 and pushes the support rod 42 inside so that the support rod 42 passes through the sleeve 2 and extends into the needle hole 21, the support rod 42 has a support rod hole 421, and the outer wall surface of the support rod hole 421 is a support rod inclined surface 422; after the driving sheet 51 passes through the disassembly rod 32 and further moves downward, it can push the support rod inclined surface 422 outward, so that the support rod 42 exits the needle hole 21.

[0033] In this way, the support rod 42 limits the deepest insertion position of the needle 6, which can prevent the needle 6 from being over-inserted. Since the driving piece 51 passes through the disassembly rod 32 and moves further downward, it can push the support rod inclined surface 422 outward, so that the support rod 42 withdraws from the needle hole 21; by pressing the operating structure 5, the needle 6 can still fall into the sharps box.

[0034] In order to prevent the support rod 42 from extending too far into the sleeve 2 , the support rod 42 preferably has a positioning flange 423 , which abuts against the sleeve 2 .

[0035] The operating structure 5 needs to be able to reset after being pressed. If the lower end of the driving piece 51 only rests on the disassembly rod inclined surface 324, the disassembly structure spring 33 pushes the disassembly rod 32 inward, and the disassembly rod inclined surface 324 can push the driving piece 51 upward to reset the operating structure 5. However, the driving piece 51 needs to be further moved downward to push the support rod inclined surface 422. In this case, the operating structure 5 cannot be reset only by the reaction of the disassembly structure 3 and the support structure 4. In order to reset the operating structure 5, the following settings can be made: the operating structure 5 includes a reset spring 53, which is located between the connecting plate 52 and the panel 1 and connected to the two.

[0036] Preferably, the lower end of the driving plate 51 has a driving slope 511, and the driving slope 511, the disassembly rod slope 324 and the support rod slope 422 are all inclined at an angle of 45°. The driving slope 511 is used to contact the disassembly rod slope 324 and the support rod slope 422 to push the disassembly rod 32 and the support rod 42.

[0037] In order to facilitate pressing, the connecting plate 52 is an annular plate coaxial with the sleeve 2. In this way, the connecting plate 52 can be pressed from all directions, which is more convenient. When the connecting plate 52 is pressed, the two driving plates 51 are driven to move downward synchronously, driving the two disassembly structures 3 and the two support structures 4.
