Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and in particular to an insulin refrigerator box. Background Technology

[0002] Insulin requires specific temperature storage conditions. The storage requirements for unopened and opened insulin are completely different. Unopened insulin is recommended to be refrigerated in the temperature range of 2℃-8℃, while opened insulin is recommended to be stored at room temperature below 28℃.

[0003] However, users often neglect proper insulin storage, storing opened insulin in home refrigerators. The expansion and contraction of the medication due to temperature changes can lead to dosage discrepancies between the injected dose and the actual dosage. Medical studies show that dosage discrepancies can cause hypoglycemia, resulting in dizziness and palpitations; or hyperglycemia, causing thirst and fatigue, thus affecting treatment efficacy. Furthermore, while opened insulin can be stored at room temperature, it's impossible to guarantee a consistently low temperature below 28°C, as temperatures can exceed 30°C. For example, in hot summer weather, indoor temperatures exceeding 30°C can cause the medication to deteriorate, rendering it unusable and jeopardizing health and safety.

[0004] Currently, the refrigerators used for insulin storage on the market typically consist of a refrigerated compartment for holding the insulin. The insulin is placed inside the compartment, the lid is closed to seal it, and the refrigerator operates to adjust the temperature inside to a suitable level for insulin storage. However, existing refrigerators can only store opened or unopened insulin in one container; they cannot separate opened and unopened insulin within a single refrigerator. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an insulin refrigerator box capable of simultaneously storing both opened and unopened insulin.

[0006] An insulin refrigerator box according to an embodiment of the present invention includes: The lower box body has a receiving cavity; A first heat-conducting element and a second heat-conducting element are spaced apart along the vertical direction. Both the first heat-conducting element and the second heat-conducting element are disposed within the receiving cavity to divide the receiving cavity into an installation cavity, a low-temperature cavity, and a normal-temperature cavity. The installation cavity is located below the low-temperature cavity, and the low-temperature cavity is located below the normal-temperature cavity. The low-temperature cavity is used to store unopened insulin, and the normal-temperature cavity is used to store opened insulin.

A semiconductor cooling chip is disposed within the mounting cavity, and the cold end of the semiconductor cooling chip is connected to the first heat-conducting element; The upper cover is rotatably connected to the lower box body to open or close the ambient temperature cavity.

[0007] The insulin refrigerator box according to the first aspect of the present invention has at least the following beneficial effects: The first heat-conducting element is located below the second heat-conducting element. The partial sidewall of the receiving cavity, the first heat-conducting element, and the second heat-conducting element enclose a low-temperature cavity. From top to bottom, the ambient temperature cavity, the low-temperature cavity, and the mounting cavity are arranged alternately. The cold end of the semiconductor cooling chip is directly connected to the first heat-conducting element, which can efficiently and actively cool the low-temperature cavity below, stabilizing its temperature within the range of ℃-℃, meeting the storage requirements of unopened insulin. The ambient temperature cavity is located above and isolated from the semiconductor cooling chip. The temperature of the ambient temperature cavity can be maintained at a relatively high level close to the ambient temperature, meeting the storage requirements of opened insulin. When taking out or putting in unopened insulin, the user opens the top cover and the second heat-conducting element in sequence. When taking out or putting in opened insulin, the user only needs to open the top cover. This effectively meets the differentiated storage needs of unopened and opened insulin at the same time, avoiding drug failure or injection dosage deviation caused by improper storage, and ensuring patient medication safety and treatment effect.

[0023] In related technologies, insulin requires specific temperature storage. The storage requirements for unopened and opened insulin are completely different. Unopened insulin is recommended to be refrigerated in the temperature range of 2℃-8℃, while opened insulin is recommended to be stored at room temperature below 28℃.

[0024] However, users often neglect proper insulin storage, storing opened insulin in home refrigerators. The expansion and contraction of the medication due to temperature changes can lead to dosage discrepancies between the injected dose and the actual dosage. Medical studies show that dosage discrepancies can cause hypoglycemia, resulting in dizziness and palpitations; or hyperglycemia, causing thirst and fatigue, thus affecting treatment efficacy. Furthermore, while opened insulin can be stored at room temperature, it's impossible to guarantee a consistently low temperature below 28°C, as temperatures can exceed 30°C. For example, in hot summer weather, indoor temperatures exceeding 30°C can cause the medication to deteriorate, rendering it unusable and jeopardizing health and safety.

[0025] Currently, the refrigerators used for insulin storage on the market typically consist of a refrigerated compartment for holding the insulin. The insulin is placed inside the compartment, the lid is closed to seal it, and the refrigerator operates to adjust the temperature inside to a suitable level for insulin storage. However, existing refrigerators can only store opened or unopened insulin in one container; they cannot separate opened and unopened insulin within a single refrigerator.

[0026] Reference Figures 1 to 5 An embodiment of the present invention provides an insulin refrigerator box, comprising a lower box body 100, a first heat-conducting element 200, a second heat-conducting element 300, a semiconductor cooling chip 400, and an upper cover 500. The lower box body 100 has a receiving cavity 110. The first heat-conducting element 200 and the second heat-conducting element 300 are spaced apart in the vertical direction and are both disposed within the receiving cavity 110, thereby dividing the receiving cavity 110 into a mounting cavity 111, a low-temperature cavity 112, and a room-temperature cavity 113. The mounting cavity 111 is located below the low-temperature cavity 112, and the low-temperature cavity 112 is located below the room-temperature cavity 113. The low-temperature cavity 112 is used to store unopened insulin. The ambient temperature chamber 113 is used to store opened insulin. The second heat-conducting element 300 is movably connected to the lower box 100 to open or close the low temperature chamber 112. The semiconductor cooling chip 400 is located in the mounting cavity 111, and the cold end of the semiconductor cooling chip 400 is connected to the first heat-conducting element 200. The upper cover 500 is rotatably connected to the lower box 100 to open or close the ambient temperature chamber 113. In this way, the temperature of the low temperature chamber 112 is lower than the temperature of the ambient temperature chamber 113, which effectively meets the differentiated storage needs of unopened and opened insulin at the same time, avoids drug failure or injection dosage deviation caused by improper storage, and ensures the patient's medication safety and treatment effect.

[0027] For example, the first heat-conducting element 200 is located below the second heat-conducting element 300. A portion of the sidewall of the receiving cavity 110, the first heat-conducting element 200, and the second heat-conducting element 300 enclose a low-temperature cavity 112. From top to bottom, the ambient temperature cavity 113, the low-temperature cavity 112, and the mounting cavity 111 are arranged sequentially at intervals. The cold end of the semiconductor cooling chip 400 is directly connected to the first heat-conducting element 200, which can efficiently and actively cool the lower low-temperature cavity 112, stabilizing its temperature within the range of 2℃-8℃, meeting the storage requirements of unopened insulin. Meanwhile, the ambient temperature cavity... Located at the top and isolated from the semiconductor cooling chip 400, the room temperature chamber 113 can maintain a relatively high temperature close to the ambient temperature, meeting the storage requirements of opened insulin. When taking out or putting in unopened insulin, the user opens the top cover 500 and the second heat-conducting component 300 in sequence. When taking out or putting in opened insulin, the user only needs to open the top cover 500. This effectively meets the differentiated storage needs of unopened and opened insulin at the same time, avoiding drug failure or injection dosage deviation caused by improper storage, and ensuring the patient's medication safety and treatment effect.

[0028] In this embodiment, a sealing structure is provided between the second heat-conducting element 300 and the lower box body 100. The sealing structure is used to seal the low-temperature cavity 112. When the second heat-conducting element 300 closes the low-temperature cavity 112, it can effectively seal the low-temperature cavity 112, which can minimize the heat exchange between the cold air in the low-temperature cavity 112 and the normal temperature cavity 113 and the external environment, ensure that the temperature field in the low-temperature cavity 112 is stable and uniform, prevent the temperature fluctuation in the low-temperature cavity 112 from exceeding the set range, and ensure the reliability of unopened insulin storage.

[0029] In this embodiment, the second heat-conducting element 300 is spaced apart from the inner peripheral wall of the receiving cavity 110 to form a heat-conducting channel 102. The low-temperature cavity 112 is connected to the normal temperature cavity 113 through the heat-conducting channel 102, so that the low-temperature air in the low-temperature cavity 112 can enter the normal temperature cavity 113 through the heat-conducting channel 102, so that the temperature in the normal temperature cavity 113 meets the storage requirements of the opened insulin.

[0030] For example, the heat conduction channel 102 extends circumferentially along the receiving cavity 110, which can increase the flow area of ​​the heat conduction channel 102, so that a large amount of low temperature air in the low temperature cavity 112 can enter the normal temperature cavity 113, so that the temperature in the normal temperature cavity 113 meets the storage requirements of opened insulin.

[0031] In this embodiment, a locking structure is provided between the second heat-conducting element 300 and the lower box body 100. The locking structure is used to restrict the second heat-conducting element 300 from opening the low-temperature cavity 112. This can prevent the second heat-conducting element 300 from being accidentally opened, thereby improving the safety and reliability of the insulin refrigerator box and preventing the temperature of the low-temperature cavity 112 from rising due to misoperation. This avoids the risk of unopened insulin deteriorating due to temperature runaway.

[0032] In this embodiment, the locking structure includes a first Velcro 310 disposed on the second heat-conducting component 300 and a second Velcro 130 disposed on the lower box body 100. One of the first Velcro 310 and the second Velcro 130 has a hook side and the other has a rough side. The hook side can connect with the rough side, which can prevent the second heat-conducting component 300 from being accidentally opened. This can improve the safety and reliability of the insulin refrigerator box, prevent the temperature of the low-temperature chamber 112 from rising due to misoperation, and thus avoid the risk of unopened insulin deteriorating due to temperature runaway.

[0033] As another implementation, the locking structure can also be a structure in which the zipper head engages with the zipper, and there is no limitation on this.

[0034] In this embodiment, the thermal conductivity of the second heat-conducting element 300 is less than that of the first heat-conducting element 200. The lower thermal conductivity of the second heat-conducting element 300 can effectively block the upward transfer of cold energy from the lower low-temperature cavity 112, which can reduce unnecessary cooling of the ambient temperature cavity 113 and help the ambient temperature cavity 113 better maintain its required higher ambient temperature. This makes the temperature zones of the low-temperature cavity 112 and the ambient temperature cavity 113 more independent and obvious, and the temperature control more precise.

[0035] In this embodiment, the lower box 100 is connected to a handle 120, which allows the user to easily carry the insulin refrigerator box.

[0036] In this embodiment, a heat sink 600 is also included. The heat sink 600 is disposed in the mounting cavity 111 and is connected to the hot end of the thermoelectric cooler 400. It can efficiently dissipate the large amount of heat generated by the hot end of the thermoelectric cooler 400 into the air in the mounting cavity 111, ensuring that the cold end of the thermoelectric cooler 400 can continuously and efficiently cool, maintain its cooling performance, and prevent the cooling efficiency from decreasing or even damaging the thermoelectric cooler 400 due to heat accumulation at the hot end of the thermoelectric cooler 400. This ensures the long-term stable operation and reliability of the entire insulin refrigerator box.

[0037] In this embodiment, the lower housing 100 is provided with a plurality of heat dissipation holes 101 arranged side by side at intervals. Each heat dissipation hole 101 is connected to the mounting cavity 111. The heat dissipated by the heat sink 600 into the air in the mounting cavity 111 can be effectively discharged to the external environment through these heat dissipation holes 101, forming a continuous heat exchange air duct, which significantly improves the heat dissipation efficiency of the entire system and further assists the heat sink 600 in maintaining the working performance of the semiconductor cooling chip 400.

[0038] It should be noted that the heat sink 600 includes heat sink fins and a cooling fan. The heat sink fins are provided with multiple heat dissipation channels arranged side by side and spaced apart. The heat sink fins are connected to the hot end of the thermoelectric cooler 400. The cooling fan can accelerate the airflow in the heat dissipation channels, thereby improving the heat dissipation efficiency of the hot end of the thermoelectric cooler 400. No limitation is made here.

[0039] This embodiment also includes a display screen 700, a controller, a first temperature detection component, and a second temperature detection component. The display screen 700, the first temperature detection component, and the second temperature detection component are electrically connected to the controller. The display screen 700 is located on the upper cover 500, and the first and second temperature detection components are both located on the lower housing 100. The first temperature detection component is used to detect the temperature of the low-temperature chamber 112, and the second temperature detection component is used to detect the temperature of the ambient temperature chamber 113. The display screen 700 is used to display the temperatures of the low-temperature chamber 112 and the ambient temperature chamber 113, realizing real-time, accurate monitoring and visualization of the temperatures of the low-temperature chamber 112 and the ambient temperature chamber 113. Users can intuitively see the current temperatures of the low-temperature chamber 112 and the ambient temperature chamber 113 through the display screen 700, clearly understand the storage status of insulin, and allow users to confirm at any time whether the storage conditions meet the requirements. Once an abnormal temperature is detected, it can be dealt with in a timely manner, greatly enhancing medication safety.

[0040] It should be noted that the controller is a control element such as a chip or PLC, the display screen 700 is a display element such as a digital tube or an LCD screen, and the first temperature detection component and the second temperature detection component are thermocouple temperature detection sensors or resistance temperature detection sensors, which are not limited here.

[0041] In this embodiment, a battery 800 is also included. The battery 800 is disposed in the mounting cavity 111 and is electrically connected to the controller to provide power to the controller. This frees the insulin refrigerator from dependence on a fixed power source and enables it to be portable and mobile. Users can easily carry it to their workplace, travel, or any other occasion to ensure the correct storage of insulin anytime and anywhere, greatly expanding the applicable scenarios and user convenience of the insulin refrigerator.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
