Description

Technical Field

[0001] This disclosure pertains to the field of insulin pen needle collection, specifically relating to an automated collection box for safety insulin pen needles. Background Technology

[0002] In insulin injection therapy, the safe disposal of used needles is an important step in preventing cross-infection and accidental punctures. Currently, most insulin pen needle collection devices on the market rely on visual identification to distinguish between new and used needles. However, for visually impaired patients, they need to touch the top of the needle to see if there is a plastic seal to identify whether the needle has been used. However, if a used needle is touched, there is usually residual medication on the top of the needle, and the touching process can easily lead to cross-contamination. However, an insulin pen needle collection box, such as the one disclosed in CN212308584U, can help users avoid needle pricks when separating needles by using a needle-removing ring, a sliding cover, and a fixing cover. It can also facilitate the collection of used needles, making it easier to centrally store and dispose of medical waste. However, it requires a separate collection box for storing unused needles. However, such solutions have significant limitations for visually impaired patients: patients cannot quickly identify the location of new and old needles by touch or hearing, and need to repeatedly touch to confirm, which can easily lead to accidental contact with contaminated needles. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this disclosure is to provide a safe insulin pen needle automatic collection box, which solves the problem that visually impaired patients have difficulty distinguishing between new and old needles when storing needles before and after use together, and that cross-infection can easily occur when distinguishing them by touch.

[0004] The objective of this disclosure can be achieved through the following technical solutions: An automatic collection box for safety insulin pen needles includes: a collection box, with a collection hole extending through the top of the collection box; The inner side of the collection box is provided with a conversion component, and a number of storage components are equidistantly arranged on the upper end of the conversion component. The storage component includes a storage tube located at the bottom of the collection hole, and a number of filling components are arranged around the outer side of the storage tube. The filling component includes a push rod, a hollow cavity, and a filler. The inner side of the storage component is coaxially provided with a hollow cavity. The push rod is slidably provided at the bottom of the hollow cavity, and the filler is provided at the upper end of the hollow cavity. A magnetic lifting assembly is provided directly below the collection hole to control the vertical displacement of the storage cylinder. When the storage component moves directly above the magnetic lifting component, the magnetic force lifts the storage tube upwards, and the characteristic sound produced by the magnetic lifting of the storage tube forms an auditory positioning mark. The filler expands radially when the push rod is pressed upward. When the needle is inserted into the storage tube, the outer wall of the needle is fixed by the radial pressure of the filler. When the pen body is separated from the needle, the filler is partially embedded in the groove at the upper end of the needle to form a physical isolation.

[0005] In some disclosures, the conversion assembly includes a transmission chain, sprockets, and a drive structure. The bottom surface of the collection box is rotatably connected to multiple sprockets, and the multiple sprockets are meshed with a transmission chain. The inner side of the transmission chain is provided with a drive structure.

[0006] In some disclosures, the drive structure includes an impeller, blades, and a knob, with the impeller rotatably connected to the bottom of the collection box via a bearing, the knob extending through the upper end of the impeller, and multiple blades arranged in an array on the outer side of the impeller, with the blades inserted between multiple adjacent storage components.

[0007] In some disclosures, the storage assembly further includes a base and a magnetic strip, with the upper end of the transmission chain fixed to the base and the magnetic strip slidably disposed on the inner side of the base.

[0008] In some disclosures, a magnetic lifting assembly is fixed to the bottom of the collection box. The magnetic lifting assembly includes a magnetic block and a base. The magnetic block is located directly below the collection hole, and the base is fitted into the bottom of the magnetic block. The magnetic block is fixed to the bottom of the collection box by the base, and the magnetic strip has the same magnetic poles on the opposite side of the magnetic block.

[0009] In some disclosures, a handguard is fixed to the upper surface of the collection box, and the handguard is coaxially arranged with the collection hole, and a guide groove is provided on the side of the collection hole away from the handguard.

[0010] In some disclosures, the filler includes a bag and cotton, the upper end of the hollow cavity is fixed with the bag and the inside of the bag is filled with cotton, and the upper outlet of the hollow cavity faces the storage tube.

[0011] In some disclosures, the push rod includes a baffle and an elastic plate, and the elastic plate is slidably disposed on the inner side of the hollow cavity. One end of the elastic plate is fixed to the baffle, and the other end of the elastic plate is fixedly connected to the filler. The inner diameter of the baffle is smaller than the outer diameter of the storage tube.

[0012] In some disclosures, a first limiting ring is fixed to the outer wall of the storage tube, and a second limiting ring is fixed to the inner wall of the base.

[0013] In some disclosures, the inner bottom surface of the storage tube is a conical groove, and a latex pad is fixed at the center of the inner bottom surface of the storage tube. Axial protrusions are equidistantly arranged on the outer wall of the first limiting ring, and a limiting block is fixed on the inner wall of the base.

[0014] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows: A fixed connection refers to a connection in which parts or components are fixed in place and there is no relative movement between them; A rotating connection is a connection between parts that allows the parts to rotate relative to each other. Threaded connections are a type of detachable fixed connection with advantages such as simple structure, reliable connection, and convenient assembly and disassembly. They are widely used in mechanical engineering and connection structure fields. A sliding connection is a connection between parts that allows the parts to slide against each other.

[0015] The beneficial effects of this disclosure are: 1. Utilizing the linkage between the magnetic lifting component and the conversion component, automatic switching and compartmenting of new and used needles is achieved. The filler is embedded in the groove of the used needle, using tactile differences to help distinguish between new and used needles. At the same time, it absorbs residual medication and forms a physical barrier between the needle and the hand, reducing the risk of cross-contamination. 2. Through the physical guidance of the conical groove, the auditory positioning of magnetic lifting, and the tactile feedback of mechanical locking, a multi-sensory collaborative operation logic is formed to help visually impaired patients reduce their reliance on vision and lower the possibility of misoperation during needle insertion, separation, and retrieval. 3. The guide groove and hand guard structure restrict the needle retrieval path. Combined with the conical groove and latex pad design of the storage tube, the needle moves along the axis and wraps around the needle tip. During operation, the hand and the needle are physically isolated, reducing the possibility of puncture or contamination. Attached Figure Description

[0019] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0020] Please refer to Figures 1 to 9 An automatic collection box for safety insulin pen needles includes: a collection box 1, and a collection hole 2 is provided through the top of the collection box 1; The inner side of the collection box 1 is provided with a conversion component 5, and a plurality of storage components 3 are provided at equal intervals on the upper end of the conversion component 5. The storage component 3 includes a storage tube 31 located at the bottom of the collection hole 2, and a plurality of filling components 4 are arranged around the outer side of the storage tube 31. The filling component 4 includes a push rod 41, a hollow cavity 42 and a filler 43, and the hollow cavity 42 is coaxially arranged on the inner side of the storage component 3. The push rod 41 is slidably arranged at the bottom of the hollow cavity 42, and the filler 43 is arranged at the upper end of the hollow cavity 42. A magnetic lifting assembly 6 is provided directly below the collection hole 2 to control the vertical displacement of the storage cylinder 31. When the storage component 3 moves directly above the magnetic lifting component 6, the magnetic force drives the storage cylinder 31 to lift upwards, and the characteristic sound generated by the magnetic lifting of the storage cylinder 31 forms an auditory positioning mark. The filler 43 expands radially when the push rod 41 is pressed upward. When the needle is inserted into the storage tube 31, the outer wall of the needle is fixed by the radial pressure of the filler 43. When the pen body is separated from the needle, the filler 43 is partially embedded in the groove at the upper end of the needle to form a physical isolation.

[0021] When the needle passes through the collection hole 2 and is placed into the corresponding storage component 3, the pen body moves downward along the storage component 3. The pen body first contacts the push rod 41 through the storage component 3, pushing the push rod 41 to move away from the push rod 41 along the hollow cavity 42. During the movement of the pen body, the filling material 43 at the end of the hollow cavity 42 away from the push rod 41 is pushed outward, squeezing the outer wall of the needle and applying circumferential pressure to the storage component 3. When the storage component 3 is lower than the upper outlet of the hollow cavity 42, the filling material 43 moves outward. At this time, the height of the filling material 43 corresponds to the connection between the needle and the pen body. Then, the pen body is rotated to separate the pen body from the needle. After the pen body is pulled upward, the force resisting the filling material 43 weakens rapidly, causing the filling material 43 to continue to move closer to the needle. The needle moves to one side of the central axis and enters the groove at the top of the needle. The filler 43 blocks the groove at the top of the needle the moment the needle separates from the pen body. When the patient wants to further confirm whether the needle has fallen into the collection chamber, the hand will first touch the filler 43 at the top of the needle during the downward exploration. The filler 43 absorbs the medicine at the top of the needle and forms a physical barrier between the filler 43 and the hand. At this time, even if the hand touches the top of the needle, cross-infection can be reduced. In addition, if the conversion component 5 at the bottom of the device malfunctions and the old and new needles are not replaced in time, when the patient touches the used needle, the difference in feel between the filler 43 at the top of the old needle and the plastic film at the top of the new needle can be used to distinguish between the old and new needles.

[0022] Please refer to Figures 2 to 3 The conversion component 5 includes a transmission chain 51, sprockets 52 and a drive structure 53. The bottom surface of the collection box 1 is rotatably connected to multiple sprockets 52, and the multiple sprockets 52 are meshed with the transmission chain 51. The inner side of the transmission chain 51 is provided with the drive structure 53. In use, the storage component 3 is fixed to the upper end of the transmission chain 51. When the drive structure 53 drives the transmission chain 51 to rotate, the transmission chain 51 meshes with the sprocket 52, so that different storage components 3 pass through the bottom of the collection hole 2 in sequence, and the storage components 3 at the bottom of the collection hole 2 can be replaced. This makes it convenient to store used and unused needles together in the collection box 1. The position of the storage component 3 can be changed by the conversion component 5, which makes it convenient for visually impaired patients to replace the needles.

[0023] Please refer to Figures 2 to 3The drive structure 53 includes an impeller 531, blades 532 and a knob 533. The bottom of the collection box 1 is rotatably connected to the impeller 531 via a bearing. The upper end of the impeller 531 passes through the collection box 1 and is provided with a knob 533. Multiple blades 532 are arranged in an array on the outer side of the impeller 531, and the blades 532 are inserted between multiple adjacent storage components 3.

[0024] In use, the impeller 531 is rotated by turning the knob 533. When the impeller 531 rotates, the blades 532 push the storage assembly 3 and the transmission chain 51 to rotate along the sprocket 52, thereby driving the transmission chain 51 to rotate. Since the gaps between the multiple storage assemblies 3 are the same, the blades 532 with appropriate spacing can be replaced according to the spacing between the storage assemblies 3, so that the impeller 531 can mesh with the storage assembly 3 during the rotation, similar to a gear and rack, so that the next set of storage assemblies 3 moves closer to the collection hole 2 directly below. At the same time, when the next set of storage assemblies 3 moves to the direct below the collection hole 2, the storage cylinder 31 can automatically pop up. Through this linkage structure, the structure of the drive structure 53 is simple and the precision requirements of the drive structure 53 are low, thus making it convenient for patients to use.

[0025] Please refer to Figures 4 to 6 The storage component 3 also includes a base 32 and a magnetic strip 33, and the upper end of the transmission chain 51 is fixed with the base 32, and the magnetic strip 33 is slidably arranged on the inner side of the base 32.

[0026] A magnetic lifting assembly 6 is fixed to the bottom of the collection box 1. The magnetic lifting assembly 6 includes a magnetic block 61 and a base 62. The magnetic block 61 is located directly below the collection hole 2, and the base 62 is fitted into the bottom of the magnetic block 61. The magnetic block 61 is fixed to the bottom of the collection box 1 through the base 62, and the magnetic strip 33 has the same magnetic pole on the opposite side of the magnetic block 61.

[0027] When the storage component 3 moves above the magnetic block 61, the magnetic block 61 and the magnetic strip 33 repel each other, thus pushing the magnetic strip 33 and the storage tube 31 upward along the axis by magnetic force. When the storage tube 31 is coaxially set with the collection hole 2, the storage tube 31 passes through the collection hole 2. At this time, even if the knob 533 is turned, it is difficult to make the conversion component 5 continue to move, so that the storage tube 31 can be stably inserted into the collection hole 2 to reduce the misalignment of the needle and the storage tube 31 when the patient's hand shakes.

[0028] Please refer to Figure 1 The upper end face of the collection box 1 is fixed with a hand guard 7, and the hand guard 7 is coaxially arranged with the collection hole 2. A guide groove 71 is provided on the side of the collection hole 2 away from the hand guard 7.

[0029] In use, the end of the guide groove 71 is directly connected to the collection hole 2, forming a guide path for the needle to be inserted into the collection hole 2. The visually impaired patient supports the outer wall of the hand protector 7 with their left hand, while holding the insulin pen body with their right hand. The needle part of the insulin pen body is inserted into the guide groove 71 on the right side of the hand protector 7, and then slid along the guide groove 71 towards the side closer to the hand protector 7 until the needle moves into the collection hole 2. After the storage tube 31 moves upward, the needle can be automatically inserted into the storage tube 31, so that the storage tube 31 and the needle part can be automatically aligned. Since the patient's left hand is on the outer wall of the hand protector 7 and the patient's right hand is holding the insulin pen body, the risk of puncturing the hand can be reduced during the process of inserting the needle into the storage tube 31.

[0030] Please refer to Figure 7 and Figure 9 The filling material 43 includes a wrapping bag 431 and cotton 432. The upper end of the hollow cavity 42 is fixed with the wrapping bag 431, and the inner side of the wrapping bag 431 is filled with cotton 432. The upper end outlet of the hollow cavity 42 faces the storage tube 31.

[0031] When the packaging bag 431 containing cotton 432 is inserted into the upper groove of the needle after injection, the cotton 432 absorbs water and stores the injection fluid on the needle when it comes into contact with the injection fluid, thereby reducing the contamination of the injection fluid to the external environment. Also, when the hand comes into contact with the filler 43, the fingers touch the side of the cotton 432 away from the needle. The filler 43 forms a physical barrier between the fingers and the upper part of the needle, so that even if the hand touches the upper part of the needle, cross-infection can be reduced.

[0032] Please refer to Figure 9 The push rod 41 includes a baffle 411 and an elastic sheet 412. The elastic sheet 412 is slidably disposed on the inner side of the hollow cavity 42. One end of the elastic sheet 412 is fixed to the baffle 411, and the other end of the elastic sheet 412 is fixedly connected to the filler 43. The inner diameter of the baffle 411 is smaller than the outer diameter of the storage tube 31.

[0033] When the storage tube 31 moves downward, it pushes the baffle 411 downward. Simultaneously, as the baffle 411 moves downward, it presses down on the elastic sheet 412, causing the elastic sheet 412 to deform and bend. This causes the elastic sheet 412 to move along the hollow cavity 42 towards the end away from the baffle 411, thereby compressing the filler 43 outward. Before the storage tube 31 is below the upper end of the hollow cavity 42, the filler 43 is compressed at the upper outlet of the hollow cavity 42. After the storage tube 31 is below the upper end of the hollow cavity 42 and the pen body separates from the needle, the pen body then... 2. The resistance of the filler 43 is removed. At this time, the filler 43 expands rapidly. The elastic sheet 412 pushes the filler 43 to move closer to the inside of the storage cylinder 31 until it enters the storage cylinder 31. This forms a filling of the upper end of the used needle. The deformation of the elastic sheet 412 and the expansion of the filler 43 establish a mechanical timing logic to reduce the risk of cross-infection caused by the hand being placed inside the needle before the filler 43 has moved into the storage cylinder 31, as well as the situation where the delayed triggering causes the patient to forget whether the needle has been ejected, resulting in the hand being suddenly clamped after being placed inside.

[0034] Please refer to Figures 6 to 9 The outer wall of the storage tube 31 is fixed with a first limiting ring 311, and the inner wall of the base 32 is fixed with a second limiting ring 321.

[0035] When the storage tube 31 moves to its bottom, the first limiting ring 311 and the second limiting ring 321 on the outer side of the storage tube 31 are misaligned. At this time, when the storage tube 31 contacts the first limiting ring 311, it undergoes elastic deformation with the second limiting ring 321 until the first limiting ring 311 and the second limiting ring 321 are misaligned. At this point, it cannot pass through the collection hole 2 only by the magnetic repulsion of the magnetic strip 33, thereby reducing the possibility of the storage tube 31 moving upward and helping to reduce the positional changes of the storage tube 31 and the filling material 43. This also makes it easier for patients to confirm whether the used needles are stored in the storage tube 31.

[0036] Please refer to Figures 6 to 9 The inner bottom surface of the storage tube 31 is a conical groove 312, and a latex pad 313 is fixed at the center of the inner bottom surface of the storage tube 31. Axial protrusions 314 are equidistantly arranged on the outer wall of the first limiting ring 311, and a limiting block 322 is fixed on the inner wall of the base 32.

[0037] As the needle pierces the storage cylinder 31, it moves along the conical groove 312 towards its center. The conical groove 312 guides the needle's sliding, reducing reliance on visual perception. Furthermore, as the inner diameter of the conical groove 312 narrows, when the needle reaches the lowest point of the storage cylinder 31, the bottom of the groove fits tightly against the outer wall of the cylinder. At this point, the needle inserts into the latex pad 313, which wraps around the needle's sharp point, reducing the risk of needle puncture during the collection of used needles. This increases the friction between the storage cylinder 31 and the needle, allowing the storage cylinder 31 to rotate when the needle is rotated. The first limiting ring 311 on 31 has passed through the second limiting ring 321. At this time, the position of the axial protrusion 314 corresponds to the position of the limiting block 322. When the injection pen is rotated, the injection pen drives the storage tube 31 to rotate. At this time, the axial protrusion 314 on the storage tube 31 abuts against the limiting block 322, thereby restricting the storage tube 31 circumferentially. At this time, continuing to rotate the injection pen can unscrew the threaded connection between the needle and the pen body, thereby separating the pen body from the needle. The abutment between the axial protrusion 314 and the limiting block 322 forms a mechanical lock, generating obvious tactile feedback, prompting the user that the needle separation stage has been entered. This transforms the complex visually dependent operation into a perceptible tactile / mechanical feedback chain, forming a closed-loop user experience.

[0038] The automatic collection box for safe insulin pen needles provided by the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0039] When using, hold the insulin pen body in your right hand and insert the needle part of the insulin pen body into the guide groove 71 on the right side of the hand guard 7. Then slide it along the guide groove 71 towards the side closer to the hand guard 7 until the needle moves into the collection hole 2. The patient rotates knob 533, which drives impeller 531 and blade 532 to rotate. When blade 532 rotates, it drives conversion component 5 to rotate, causing multiple storage components 3 on conversion component 5 to move below collection hole 2. When the storage component 3 moves directly below the collection hole 2, the magnetic strip 33 at the bottom of the storage component 3 is directly above the magnetic block 61. The magnetic block 61 and the magnetic strip 33 repel each other. The magnetic force of the magnetic block 61 and the magnetic strip 33 drives the magnetic strip 33 to move upward along the base 32 until it passes through the collection hole 2. At this time, the needle automatically falls into the collection hole 2. The sound of the storage tube 31 passing through the collection hole 2 can remind the patient to proceed to the next step. At this time, press the needle down to insert the needle into the latex pad 313 along the conical groove 312, and drive the storage tube 31 to move downward. The bottom of the storage tube 31 pushes the baffle 411 to move downward, and pushes the elastic sheet 412 to move to the side of the filler 43 through the baffle 411. The elastic sheet 412 bends and deforms to push the filler 43 out of the hollow cavity 42.

[0040] Simultaneously, when the first limiting ring 311 on the storage tube 31 passes through the second limiting ring 321, rotating the injection pen utilizes the friction between the injection pen and the conical groove 312 to drive the storage tube 31 to rotate. Continuing to rotate the injection pen will loosen the threaded connection between the needle and the pen body. After the pen body and needle separate, the patient can remove the pen body. At the moment the pen body is removed, the resistance of the pen body sidewall to the filler 43 decreases, and the filler 43 enters the storage tube 31 and blocks the needle. The storage tube 31 is restricted by the second limiting ring 321 and will not move upward quickly to prevent the filler 43 from misaligning with the storage tube 31 again. At the same time, since the used storage component 3 will not spring back when it moves to the bottom of the collection hole 2, visually impaired patients can judge whether the storage tube 31 pops out when looking for unused needles. When the storage tube 31 pops out, it protrudes from the upper surface of the collection box 1, making it convenient for visually impaired patients to retrieve.
