Description
An insulin pen refrigeration cup Technical Field
[0001] This utility model belongs to the field of medical device technology, and in particular relates to a refrigerator cup for an insulin pen. Background Technology
[0002] Diabetes is a common endocrine and metabolic disease, requiring patients to self-inject insulin using insulin pens and take oral hypoglycemic drugs. Insulin use is temperature-sensitive and must be stored in a low-temperature environment. For users who need to travel, existing storage devices present several inconveniences. Most existing insulin thermos cups on the market are designed to store multiple insulin cartridges, while the insulin pens themselves need to be stored separately. There are also insulated medicine boxes that can store both insulin pens and cartridges simultaneously. However, both types of products share a significant problem: their large size makes them unportable. Whether traveling, on business trips, or short daily outings, their large size causes inconvenience and increases the burden of carrying them. Furthermore, some devices using foam as insulation material have unsatisfactory insulation performance. To achieve a certain insulation time, the thickness of the foam insulation layer must be increased, which not only further increases the overall size but also makes the device bulky. Moreover, the foam material itself has limited protective properties and cannot provide a reliable storage environment for insulin. In addition, existing devices also have shortcomings in their power supply components. Many devices' power components cannot be charged independently and are difficult to replace at any time. This makes it difficult for users to replenish the power in time to maintain the low-temperature storage environment required for insulin when the device runs out of power while they are out, which limits the convenience of using the device in different scenarios.
[0003] Utility Model Content
[0004] To address the shortcomings of the existing technology, the purpose of this invention is to provide an insulin pen refrigeration cup that can simultaneously store the insulin pen and the insulin cartridge. While meeting storage requirements, it significantly reduces the size, improves portability, and makes it easy for users to carry in various travel scenarios.
[0005] To achieve the above objectives, this utility model provides a refrigerator cup for an insulin pen, wherein the insulin pen contains an insulin cartridge, also known as insulin injection solution, comprising...
[0006] A cooling assembly includes a thermoelectric cooler, a heat-conducting component, and a cooling fan. The thermoelectric cooler includes a cold end and a hot end, with the hot end in contact with the heat-conducting component.
[0007] A cooling cylinder includes a sealed end and an open end, wherein the cold end is in contact with the sealed end.
[0008] A cup lid adapted to house the cooling component, wherein the sealing end is fixedly connected to the semiconductor cooling chip and / or the cup lid.
[0009] The cup body includes a cup wall and a heat-insulating cavity formed by the cup wall, the open end extends into the heat-insulating cavity, the cup lid is removable to close the heat-insulating cavity, and the cooling component maintains a low temperature inside the heat-insulating cavity.
[0010] Wherein: the cooling cylinder or the heat preservation cavity defines a receiving space that can accommodate up to one or two insulin pens, the receiving space is also suitable for accommodating the insulin pen cartridge, and / or the diameter of the receiving space is between 20 mm and 50 mm.
[0011] Preferably, the diameter of the receiving space is the inner diameter of the cooling cylinder or the inner diameter of the cup.
[0012] Preferably, two insulin pens or one insulin pen and one insulin cartridge are inserted side-by-side into the receiving space through the open end. It is understood that the diameter of the insulin cartridge is smaller than that of the insulin pen, and the length of the insulin cartridge is also smaller than that of the insulin pen; two to three insulin cartridges can be arranged end-to-end in the receiving space. This design helps to shorten the length of the cooling tube and the cup, resulting in a more compact and portable structure.
[0013] Preferably, the heat preservation cavity includes a cup opening, and two insulin pens or one insulin pen and one insulin pen cartridge are adapted to be inserted side by side into the receiving space through the cup opening. At this time, the distance between the cooling cylinder and the bottom of the cup limits the height of the receiving space, that is, limits the number of insulin pen cartridges that can be arranged end to end.
[0014] Preferably, the cup wall includes an inner wall, an outer wall, and a hollow cavity disposed between the two, wherein the hollow cavity is in a vacuum state. An insulation gap exists between the cooling cylinder and the inner wall. This vacuum insulation structure is lighter and more portable than traditional insulation materials, aligning with the product's portability.
[0015] As a preferred design, insulin pens and insulin cartridges are generally irregular shapes, allowing a portion of the insulin pen or cartridge to enter the insulation gap. This design allows the insulin pen or cartridge to fit more closely with the cooling cylinder, improving space utilization and making the placement of the insulin pen in the refrigerated cup more efficient.
[0016] Furthermore, the cooling cylinder includes a clearance groove, through which a portion of the insulin pen or a portion of the insulin pen cartridge can extend into the insulation cavity.
[0017] Preferably, the insulin pen refrigeration cup further includes a power supply component suitable for powering the refrigeration component. The cup lid forms a first cavity and a second cavity arranged side by side. The first cavity is suitable for accommodating the refrigeration component, and the second cavity houses a refrigeration control circuit board. The power supply component is disposed below the second cavity, and the refrigeration control circuit board is electrically connected to the refrigeration component and the power supply component, respectively.
[0018] The interior of the cup lid is rationally planned with different cavities to accommodate various components. This meticulous spatial layout makes full use of the limited space inside the lid, further compressing the overall size of the device and enabling the integration of multiple functions within a confined space. There is no need to install cooling components and control circuit boards separately in different locations on the cup body, eliminating the need for cumbersome wiring connections. This greatly simplifies the production and assembly process, improves production efficiency, and also reduces the risk of malfunctions that may arise from complex assembly.
[0019] Preferably, the semiconductor cooling chip is horizontally disposed in the first cavity and the first cavity is divided to form a heat-conducting cavity and a cold-conducting cavity. The heat-conducting cavity is adapted to accommodate the heat-conducting fan and the heat-conducting component. The cup lid is formed with an air inlet and an air outlet adapted to communicate with the heat-conducting cavity. The closed end is adapted to extend into the cold-conducting cavity. The cup body extends into the cold-conducting cavity and is detachably connected to the cup lid.
[0020] Specifically, the first cavity is cylindrical, the cooling cavity is provided with an internal thread structure, the cup body is formed with an external thread structure, and the cup body is threadedly connected to the cup lid.
[0021] Preferably, the heat-conducting fan includes a fan body and a fan frame adapted to mount the fan body, the fan frame being snapped onto the cup lid.
[0022] Preferably, the power supply assembly includes a battery housing, which in turn includes an annular shell that conforms to the shape of the cup. The power supply assembly and the cup together support the insulin pen refrigeration cup. Because the annular shell fits the shape of the cup, gaps or empty areas caused by shape mismatch are avoided, allowing the power supply assembly to be cleverly integrated into the overall structure, resulting in higher integration. Specifically, the cup includes a first bottom surface, and the battery housing includes a second bottom surface. The first and second bottom surfaces together support the insulin refrigeration cup, making it more stable. The first cavity and the second cavity are connected for easy wiring.
[0023] Preferably, the battery casing is provided with an anti-slip pad on the side away from the cup body. The anti-slip pad is a vertical plane, which provides a more stable plane for the user, making it easier for the fingers to apply lateral force, preventing the cup from rotating or sliding in the hand, and making one-handed operation easier and more accurate.
[0024] Preferably, the power supply assembly includes a rechargeable battery and a power control circuit board disposed within the battery housing. The power control circuit board is provided with a charging interface, which is embedded in the battery housing. The battery housing is detachably connected to the cup lid. The power control circuit board is in contact or pressure contact with the refrigeration control circuit board.
[0025] Preferably, the cooling control circuit board is provided with a plurality of contact pins, the power control circuit board is provided with a plurality of contact pin sockets, the contact pin sockets are provided with metal springs, and the metal springs are in close contact with the contact pins to achieve conduction.
[0026] Specifically, the bottom of the second cavity is provided with a guide block and several cantilever buckles. The guide block has a hollow structure to provide deformation space for the cantilever buckles. The guide block is recessed inward to form a limiting groove, and at least part of the stylus extends into the limiting groove. The upper end of the battery shell is formed with a guide cavity suitable for cooperating with the guide block and a buckle groove suitable for cooperating with the cantilever buckles. A limiting part is protruding in the guide cavity, and the stylus socket is disposed in the limiting part. The limiting part and the limiting groove are inserted and cooperated to guide the stylus socket to cooperate with the stylus. This realizes convenient connection and conduction between the power supply component and the cooling control circuit board, which is convenient for charging and equipment control. At the same time, the detachable connection method facilitates battery replacement and equipment maintenance.
[0027] Preferably, the cup lid is equipped with an operation button and a display unit, both of which are electrically connected to the refrigeration control circuit board. The operation button inputs control commands to the refrigeration control circuit board to control the refrigeration components, and the display unit is suitable for providing refrigeration temperature and battery power, so as to facilitate user operation and real-time understanding of the device's operating status and improve the user experience.
[0028] The beneficial effects of this utility model are:
[0029] By incorporating a cooling cylinder that can hold at most one insulin pen and one insulin cartridge, the overall structure becomes more compact, significantly reducing the volume of the insulin cooling cup and meeting portability requirements, making it easy for users to carry in various travel scenarios. On the other hand, it can more accurately and quickly adjust the internal temperature to reach and maintain the required low temperature, while the volume of the power supply component that powers the cooling component can also be reduced accordingly, thus achieving an overall lightweight design.
[0030] Vacuum insulation offers better insulation performance than foam insulation and is also lighter. It can effectively maintain a low-temperature environment without the need for a thick insulation layer, avoiding the increase in volume caused by the insulation structure and achieving a compact design.
[0031] By incorporating a replaceable power supply component, the power supply can be charged independently, and the battery can be easily removed and replaced when the power is low while out and about. This ensures that the device maintains a low-temperature environment at all times, meeting the requirement that insulin is always kept under suitable storage conditions. For example, users can use a power bank or other devices to charge the battery separately via the charging port while traveling, or quickly replace the battery with a fully charged one when it runs out of power, ensuring that the insulin's refrigerated storage environment remains unaffected.

Detailed Implementation
[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0040] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.
[0041] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0042] As shown in Figures 1-6, an insulin pen cooling cup is provided. The insulin pen contains an insulin cartridge and includes a cup lid 100, a cup body 200, and a power supply assembly 300. The cup lid 100 integrates a cooling assembly, a cooling cylinder 500, a cooling control circuit board 601, an operation button 602, and a display unit 603. The cup body 200 includes a cup wall 201 and a heat-insulating cavity 202 formed by the cup wall 201. The cup lid 100 has a first cavity 101 and a second cavity 102 arranged side by side. The first cavity 101 is adapted to house a cooling component, and the second cavity 102 houses a cooling control circuit board 601. An operation button 602 and a display unit 603 are embedded in the cup lid 100 adjacent to the second cavity 102, and both are electrically connected to the cooling control circuit board 601. The operation button 602 inputs control commands to the cooling control circuit board 601 to control the cooling component. The display unit 603 is adapted to provide the cooling temperature and battery power 302, facilitating user operation and real-time monitoring of the device's operating status, thus improving the user experience. A power supply component 300 is located below the second cavity 102. The cooling control circuit board 601 is electrically connected to both the cooling component and the power supply component 300. The first cavity 101 and the second cavity 102 are connected for easy wiring. The power supply component 300 is adapted to provide power to the cooling component and the display unit 603. The cooling component includes a semiconductor cooling chip 401, a heat-conducting element 402, and a cooling fan 403. The first cavity 101 is cylindrical. The semiconductor cooling chip 401 is horizontally disposed in the first cavity 101 and divides the first cavity 101 to form a heat-conducting cavity 103 and a cold-conducting cavity 104. The heat-conducting cavity 103 is suitable for accommodating a heat-conducting fan and a heat-conducting component 402. The cup lid 100 is formed with an air inlet 106 and an air outlet 105 suitable for communicating with the heat-conducting cavity 103.
[0043] It should be clarified that the placement of the air inlet 106 and the air outlet 105 is flexible. One feasible arrangement is to place the air inlet 106 on the end face of the cup lid 100 and the air outlet 105 on the circumferential surface of the cup lid 100. Alternatively, the air inlet 106 can be placed on the circumferential surface of the cup lid 100, while the air outlet 105 is placed on the end face of the cup lid 100. Regardless of the arrangement, it should be considered within the scope of protection of this patent, and the specific placement of the air inlet 106 and the air outlet 105 should not limit the scope of protection of this patent. This design aims to provide multiple feasible solutions for achieving effective communication and heat exchange between the cup lid and the heat-conducting cavity, to meet different usage scenarios and design requirements.
[0044] Specifically, the thermoelectric cooler 401 includes a cold end and a hot end, with the hot end in contact with the heat-conducting component 402, meaning the thermoelectric cooler 401 supports the heat-conducting component 402. The heat-conducting fan includes a fan body 404 and a fan frame 405 adapted to mount the fan body 404, with the fan frame 405 snapped onto the cup lid 100. The cooling cylinder 500 includes a sealed end 501 and an open end 502. The sealed end is adapted to extend into the cooling cavity 104 and be in contact with the cold end, and the sealed end 501 is fixedly connected to the thermoelectric cooler 401. The open end 502 extends into the insulation cavity 202, and the cup lid 100 can be detachably sealed to close the insulation cavity 202, allowing the cooling components to maintain a low temperature inside the insulation cavity 202. Specifically, the cooling cavity 104 has an internal thread structure, and the cup body 200 has an external thread structure, with the cup body 200 threadedly connected to the cup lid 100. The cooling cylinder 500 has a storage space that can accommodate up to one or two insulin pens, and is also suitable for accommodating insulin cartridges. The inner diameter of the cooling cylinder is 40mm. Two insulin pens can be inserted side-by-side into the cooling cylinder 500 through their open ends 502. Insulin pens and insulin cartridges are also suitable for being inserted side-by-side into the cooling cylinder 500 through their open ends 502. It is understood that the diameter and length of the insulin cartridge are smaller than that of the insulin pen. Two to three insulin cartridges can be arranged end-to-end in the cooling cylinder 500 or the warming chamber 202. The warming chamber 202 or the storage space has a volume of 200ml. One insulin pen containing an insulin cartridge and one spare insulin cartridge can meet the needs of a severely diabetic patient for half a month, or a mild diabetic patient for one month, fully meeting the needs of short trips or business trips.
[0045] In this embodiment, the cup wall 201 includes an inner wall, an outer wall, and a hollow cavity (not shown in the figure) disposed between the two, the hollow cavity being in a vacuum state. A heat-insulating gap exists between the cooling cylinder 500 and the inner wall. The vacuum insulation structure is lighter and more portable than traditional insulation materials, aligning with the product's portable positioning.
[0046] In this embodiment, the cooling cylinder 500 includes a clearance groove 503, which extends from the open end 502 to the closed end. Common insulin pens and insulin cartridges are generally irregular shapes, allowing a portion of the insulin pen or cartridge to extend into or pass through the clearance groove into the insulation gap. The wall thickness of the cooling cylinder 500 is 1 mm. This allows the insulin pen or cartridge to fit more closely to the cooling cylinder 500, improving space utilization and better securing its position, preventing or reducing its movement within the cooling cylinder 500.
[0047] In this embodiment, the power supply assembly 300 includes a battery housing 301, a rechargeable battery 302 disposed in the battery housing 301, and a power control circuit board 303. The power control circuit board 303 is provided with a charging interface 311, which is embedded in the battery housing 301. The battery housing 301 is detachably connected to the cup lid 100. The power control circuit board 303 is in contact with the cooling control circuit board 601. Specifically, the bottom of the second cavity 102 is provided with a guide block 107 and two symmetrically arranged cantilever buckles 108. The guide block 107 has a hollow structure to provide deformation space for the cantilever buckles 108. The guide block 107 is recessed inward to form a limiting groove 109. The cooling control circuit board 601 is provided with a number of contact pins 604, at least some of which extend into the limiting groove 109. The upper end of the battery 302 shell has a guide cavity 307 suitable for cooperating with the guide block 107 and a buckle groove 308 suitable for cooperating with the cantilever buckles 108. The 7-inch inner protrusion has a limiting part 309. The power control circuit board 303 is provided with a number of contact pin sockets 310. The contact pin sockets 310 are located in the limiting part. The limiting part 309 and the limiting groove 109 are inserted and cooperate to guide the contact pin sockets 310 and the contact pins 604 to cooperate. The contact pin sockets 310 have built-in metal springs. The metal springs are in close contact with the contact pins 604 to realize convenient connection and conduction between the power component 300 and the cooling control circuit board 601, which is convenient for charging and equipment control. At the same time, the detachable connection method facilitates the replacement of the battery 302 and equipment maintenance.
[0048] In this embodiment, the battery housing 301 includes an annular housing 304 that matches the shape of the cup body 200. The power supply assembly 300 and the cup body 200 together support the insulin pen refrigeration cup. Because the annular housing 304 is shape-fitted to the cup body 200, gaps or empty areas caused by shape mismatch are avoided, allowing the power supply assembly 300 to be cleverly integrated into the overall structure, resulting in higher integration. Specifically, the cup body 200 includes a first bottom surface 203, and the battery housing 301 includes a second bottom surface 306. The first bottom surface 203 and the second bottom surface 306 together support the insulin refrigeration cup, providing greater stability. An anti-slip pad 305 is provided on the side of the battery housing 301 away from the cup body 200. The anti-slip pad 305 is a vertical plane, providing a more stable surface for the user, facilitating the application of lateral force by the fingers, preventing the cup from rotating or sliding in the hand, making single-handed operation easier and more accurate.
[0049] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
