Description

Technical Field

[0001] This invention relates to the field of medical protective equipment technology, and more specifically to a smart insulin pen needle disposal box with a reminder function. Background Technology

[0002] Insulin pen needle disposal boxes, often referred to as sharps containers or disposable needle disposal containers, are specialized containers for the safe collection and temporary storage of used insulin pen needles, syringes, and other sharp medical waste. Their robust, puncture-resistant materials effectively protect family members and others, preventing bacterial infections from needle pricks and thus enhancing home safety. In summary, the inventors have found that existing insulin pen needle disposal boxes have the following main defects: Because current insulin pen needle disposal boxes typically have a simple structure, they only serve a storage and protection function after the patient inserts the needle, but there is still a gap between the needle and the disposal box, leading to instability and easy loss during subsequent retrieval. Furthermore, they do not provide a confirmation function after the needle is inserted, making it difficult for the patient to determine if the needle is properly inserted. This reduces the effectiveness and intelligent features of the current disposal boxes. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical objective is: a smart insulin pen needle waste box with reminder function, the structure of which includes: anti-slip plate, main box, charging slot, positioning buckle, groove, smart reminder structure, and protective cover.

The groove is opened inside the main box and determines the position of the smart reminder structure. The smart reminder structure is powered on by the main box and its upper end is covered by the protective cover.

[0004] As a further improvement of the present invention, the intelligent reminder structure is provided with a trigger structure, the upper end of the trigger structure is connected to a vertical sleeve and the edge of the vertical sleeve is provided with a reminder light strip, and a limit plate is provided at the upper end of the vertical sleeve to determine the position of the internal pushing structure.

[0005] As a further improvement of the present invention, the triggering structure is further provided with an energizing block, the upper end of which is connected to a parallel plate and a groove is opened in the center of the parallel plate and a control block is mounted thereon, and an energizing slot is opened at the edge of the parallel plate.

[0006] As a further improvement of the present invention, the trigger structure of the intelligent reminder structure utilizes the power-conducting block inserted into the main box for power connection. Then, the control block at the center of the groove of the parallel plate and the internal pushing structure of the vertical sleeve are on the same vertical center line, and the lower end of the reminder light strip of the vertical sleeve is inserted into the power-conducting groove to trigger the control block.

[0007] As a further improvement of the present invention, the anti-slip plate is made of rubber and its area is the same as that of the main box. The charging slot of the main box is located at the side edge. The positioning buckles of the main box are provided in three sets and set in a parallel direction. The groove is opened in a vertical direction to provide loading space for the smart reminder structure. The protective cover is parallel to the upper end of the main box.

[0008] As a further improvement of the present invention, the triggering structure is perpendicular to the vertical sleeve, the reminder light strips on the edge of the vertical sleeve are set in a symmetrical orientation, the limiting plate is square in shape and perpendicular to the upper end of the vertical sleeve, and the pushing structure is inside the vertical sleeve.

[0009] As a further improvement of the present invention, the energized block and the parallel plate form a "T" shape, and the control block is vertically embedded in the center of the groove of the parallel plate. The control block is electrically connected to the energized block through a line, and the energized groove is located at the edge of the parallel plate and is electrically connected to the lower ends of the two reminder light strips.

[0010] As a further improvement of the present invention, the pushing structure is provided with a toggle block, one end of the toggle block is connected to a slider and the other end of the slider is connected to a pressing block, the pressing block has a clamping groove at its center and a protrusion at its lower center.

[0011] As a further improvement of the present invention, the actuating block and the slider are perpendicular to each other and are symmetrically positioned at the edge of the pressing block. The groove of the pressing block is circular, and the protrusion is solid and is vertically fixed at the lower center of the pressing block.

[0012] As a further improvement of the present invention, the protrusion is also provided with a locking bolt, which is located at the edge of the positioning disk. A block is connected to the center of the positioning disk, and a support rod is mounted inside the block. One end of the support rod is connected to a contact block.

[0013] As a further improvement of the present invention, the locking bolt is arranged in a ring-shaped position at the edge of the positioning disk, and the block of the positioning disk is circular in shape and has four support rods inside to determine the position of the contact block. The contact block presses down on the control block by sliding down the block.

[0014] As a further improvement of the present invention, the protective cover is provided with a pull block, the lower end of the pull block is connected to a solid plate, the edge of the solid plate is connected to an adsorption frame, and an insertion block is provided at the lower edge of the adsorption frame, with a balance block connected to the edge of the insertion block.

[0015] As a further improvement of the present invention, the pull block is perpendicular to the upper center of the solid plate, the edge of the solid plate is covered by the adsorption frame, the adsorption frame is parallel to the upper edge of the main box, and the lower edge of the adsorption frame is equipped with two insert blocks and set in a symmetrical orientation.

[0016] As a further improvement of the present invention, the solid plate is further provided with splicing blocks, which are disposed at the edge of the plate body and a central plate is disposed in the plate body, and the central plate is equipped with a top block.

[0017] As a further improvement of the present invention, the splicing blocks are distributed on the edge of the plate and connected to the inner wall of the adsorption frame. The plate and the central plate are parallel to each other. The top block connected to the surface of the central plate is set in a vertical orientation and covers the upper end of the vertical sleeve.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, with its improved intelligent reminder structure, allows the trigger structure to be electrically connected vertically to the inside of the main box. After the pen needle is inserted into the pushing structure, the pushing structure slides down, thereby pressing down the control block in the central groove of the parallel plate at the position of the energized block. This pressing down of the control block, combined with the energized groove, illuminates the reminder light strip on the edge of the vertical sleeve, achieving the effect of reminding that the needle is inserted securely. If it is not inserted securely, the reminder light strip will not light up, thus improving the usability of the waste box and meeting the characteristics of having a reminder function, further enhancing the safety factor of insulin pen needle recycling.

[0019] 2. With the improved push-moving structure, the slider passes through the edge of the vertical sleeve without the warning light strip. After the pen needle is driven down by the pressing block and the clamping groove, when the retrieval personnel are retrieving the needle, they can be manually driven up vertically by the external toggle block, forcing the needle to vertically detach from the vertical sleeve position. This improves the convenience of retrieval and avoids other safety hazards caused by forceful pulling. At the same time, the pressing block can be combined with the contact block equipped in the lower center to press down the control block, and the center alignment cover can prevent the center point from being misaligned.

[0020] 3. The invention improves upon the protective cover by using a pull block to control the solid plate, enabling convenient control of the solid plate. After the cover is closed, the connection between the cover and the upper part of the main box is strengthened by the cooperation of the adsorption frame and the insert block, preventing the protective cover from automatically falling off during the recycling process and exposing bacteria. Furthermore, the top block in the solid plate can be used to cover the top of the vertical sleeve a second time, improving the airtightness of the cover for the used needle.

[0029] The present invention will be further described below with reference to the accompanying drawings: Example 1: Figures 1 to 5 As shown: This invention provides a smart insulin pen needle disposal box with a reminder function. Its structure includes: anti-slip plate 1, main box 2, charging slot 3, positioning buckle 4, collection slot 5, smart reminder structure 6, and protective cover 7. The anti-slip plate 1 is parallel to the lower end of the main box 2 and the side of the main box 2 is integrated with the charging slot 3 and positioning buckle 4. The collection slot 5 is opened inside the main box 2 and determines the position of the smart reminder structure 6. The smart reminder structure 6 is powered on by the main box 2 and its upper end is covered by the protective cover 7.

[0030] The intelligent reminder structure 6 is provided with a trigger structure 61. The upper end of the trigger structure 61 is connected to a vertical sleeve 62 and an reminder light strip 63 is provided on the edge of the vertical sleeve 62. A limit plate 64 is provided on the upper end of the vertical sleeve 62 to determine the position of the internal pushing structure 65.

[0031] The triggering structure 61 is further provided with an energizing block 611. The upper end of the energizing block 611 is connected to a parallel plate 612, and the center of the parallel plate 612 has a groove 613 and a control block 614. An energizing groove 615 is opened at the edge of the parallel plate 612.

[0032] In this process, the triggering structure 61 of the intelligent reminder structure 6 uses the power block 611 inserted into the main box 2 for power connection. Then, the center position control block 614 of the groove 613 of the parallel plate 612 and the internal pushing structure 65 of the vertical sleeve 62 are on the same vertical center line. Then, the lower end of the reminder light strip 63 of the vertical sleeve 62 is inserted into the power groove 615 to trigger the control block 614.

[0033] The anti-slip plate 1 is made of rubber and has the same area as the main box 2. The charging slot 3 of the main box 2 is located at the side edge. The positioning buckle 4 of the main box 2 is provided in three sets and set in a parallel direction. The collection slot 5 is opened in a vertical direction to provide loading space for the smart reminder structure 6. The protective cover 7 is parallel to the upper end of the main box 2.

[0034] The trigger structure 61 is perpendicular to the vertical sleeve 62. The reminder light strip 63 on the edge of the vertical sleeve 62 is set in a symmetrical position. The limiting plate 64 is square and perpendicular to the upper end of the vertical sleeve 62. The pushing structure 65 is inside the vertical sleeve 62.

[0035] The energized block 611 and the parallel plate 612 form a "T" shape. The control block 614 is vertically embedded in the center of the groove 613 of the parallel plate 612. The control block 614 is electrically connected to the energized block 611 through a line. The energized groove 615 is located at the edge of the parallel plate 612 and is electrically connected to the lower ends of the two reminder light strips 63.

[0036] The pushing structure 65 is provided with a toggle block 651. One end of the toggle block 651 is connected to a slider 652 and the other end of the slider 652 is connected to a pressing block 653. The pressing block 653 has a clamping groove 654 at its center and a protrusion 655 at its lower center.

[0037] The actuating block 651 and the slider 652 are perpendicular to each other and are symmetrically positioned at the edge of the pressing block 653. The groove 654 of the pressing block 653 is circular, and the protrusion 655 is solid and is vertically fixed at the lower center of the pressing block 653.

[0038] The protrusion 655 is also provided with a locking bolt 6551, which is located at the edge of the positioning disk 6552. The center of the positioning disk 6552 is connected to a block 6553, and a support rod 6554 is mounted inside the block 6553. One end of the support rod 6554 is connected to a contact block 6555.

[0039] The locking bolt 6551 is arranged in a ring shape at the edge of the positioning disk 6552, and the block 6553 of the positioning disk 6552 is circular in shape and has four support rods 6554 inside to determine the position of the contact block 6555. The contact block 6555 presses down on the control block 614 by sliding down the block 6553.

[0040] The specific functions and operation procedures of this embodiment are as follows: In this invention, the insulin pen needle waste box can be stably placed in a safe location in the patient's home using the anti-slip plate 1. The charging slot 3 replenishes the battery inside the main box 2. The intelligent reminder structure 6 inside the collection slot 5 reminds the patient to insert the used pen needle securely. The protective cover 7 covers the top of the main box 2 for secondary protection. Finally, after collection by recycling personnel, the entire waste box can be positioned using the positioning buckle 4 for stable recycling. The trigger structure 61 of the intelligent reminder structure 6 can carry the vertical sleeve 62 and be installed inside the main box 2. The reminder light strip 63 on the edge of the vertical sleeve 62 can then be electrically connected to the trigger structure 61, and subsequently, the limiting plate 64 provides positioning. The push structure 65 can slide vertically downwards. After the pen needle is inserted, it drives the push structure 65 downwards until it presses down the trigger structure 61, then activates the reminder light strip 63. The reminder light strip 63 illuminates to indicate that the needle is fully inserted; conversely, if the reminder light strip 63 is not illuminated, it indicates that the needle is not fully inserted. This allows the waste box to function as a reminder, improving its usability. The parallel plate 612 of the trigger structure 61 can be electrically connected to the inside of the main box 2 via the lower energizing block 611. The groove 613 of the parallel plate 612 determines the position of the control block 614, while the edge energizing groove 615 is electrically connected to the lower end of the reminder light strip 63. After the push structure 65 slides down, the center position can then press down the control block 614. 14. Pressing down the control block 614 allows the reminder light strip 63 to be activated via the energizing groove 615. Conversely, when the push structure 65 slides up and resets, the control block 614 loses its force, and the internal rebound spring rebounds, thus turning off the reminder light strip 63. This improves the durability of the waste box. Furthermore, the slider 652 on the edge of the pressing block 653 of the push structure 65 passes through the edge of the vertical sleeve 62 to carry the reminder light strip 63. Then, the toggle block 651 is positioned outside the vertical sleeve 62. Therefore, after the needle is inserted into the groove 654 of the pressing block 653, the needle slides down steadily in conjunction with the slider 652 until the protrusion 655 presses and fixes the control block 614, thus completing the needle insertion. Conversely, the recycling person... When the operator needs to remove the needle, the slider 652 can be moved upwards by the action of the actuating block 651, achieving a quick needle removal effect. This replaces the original method of directly pulling out the needle, which could cause component damage and other safety hazards. Furthermore, the surface of the actuating block 651 can carry an auxiliary pull rod to facilitate control and prevent the difficulty in control due to the small spacing inside the collection tank 5. Finally, the protrusion 655 can be stably installed at the lower end of the pressing block 653 through the positioning plate 6552 and the locking bolt 6551. Then, the center position of the block 6553 of the positioning plate 6552 can be forcibly determined by the support rod 6554, so that the contact block 6555 can cover the upper end of the control block 614 according to its own area.This achieves a vertical downward pressure effect, thus improving the accuracy of triggering.

[0041] Example 2: Figures 6 to 7 As shown: This invention provides a smart insulin pen needle disposal box with a reminder function. Its structure includes a protective cover 7 having a pull block 71, a solid plate 72 connected to the lower end of the pull block 71, an adsorption frame 73 connected to the edge of the solid plate 72, an insertion block 74 provided at the lower edge of the adsorption frame 73, and a balance block 75 connected to the edge of the insertion block 74.

[0042] The pull block 71 is perpendicular to the upper center of the solid plate 72. The edge of the solid plate 72 is covered by the adsorption frame 73. The adsorption frame 73 is parallel to the upper edge of the main box 2. The lower edge of the adsorption frame 73 is equipped with two insert blocks 74 and is set in a symmetrical position. The insert blocks 74, together with the balance block 75, are inserted into the interior of the main box 2.

[0043] The solid plate 72 is further provided with a splicing block 721, which is located at the edge of the plate body 722 and a central plate 723 is provided in the plate body 722, with a top block 724 mounted on the central plate 723.

[0044] The splicing blocks 721 are distributed on the edge of the plate 722 and connected to the inner wall of the adsorption frame 723. The plate 722 and the center plate 723 are parallel to each other. The top block 724 connected to the surface of the center plate 723 is set in a vertical orientation and covers the upper end of the vertical sleeve 62.

[0045] The specific functions and operation procedures of this embodiment are as follows: In this invention, the solid plate 72 of the protective cover 7 can be easily controlled by the upper pull block 71. Then, the adsorption frame 73 on the edge of the solid plate 72 will be parallel to the upper edge of the main box 2, thereby improving the connection with the upper edge of the main box 2 through the adsorption effect, and improving the firmness of the cover protection. In addition, the cooperation of the edge insert block 74 and the balance block 75 can restrain the connection position between the main box 2 and the protective cover 7, improving the accuracy of splicing. Subsequently, the plate body 722 of the solid plate 72 will be connected to the adsorption frame 73 through the edge splicing block 721. Then, the top block 724 carried by the center plate 723 of the plate body 722 can press the upper end of the vertical sleeve 62 a second time. In combination with the adsorption frame 73, the needle can be covered a second time, improving the firmness of the protection and preventing automatic detachment during recycling and transportation, thus further improving the safety factor of the waste box.

[0046] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solutions described in this invention, or by designing similar technical solutions by those skilled in the art under the inspiration of the technical solutions described in this invention, falls within the protection scope of this invention.
