Description

Technical Field

[0001] The invention relates to the technical field of insulin storage equipment, in particular to a portable insulin insulation box. Background Art

[0002] Insulin is a first-line drug for the treatment of diabetes and is widely used in clinical practice. It is a protein hormone and has strict temperature requirements for its storage. Unopened insulin pen refills must be stored at 2-8°C to maintain their activity and efficacy. Although the refills of insulin pens in use can be stored at normal temperature (around 20°C, not exceeding 25°C to 30°C), they will still be affected if the room temperature exceeds 30°C. However, due to the need to carry it outside, traditional storage methods for insulin pen refills are difficult to meet the continuous constant low temperature (2-8°C) storage requirements.

[0003] In the prior art, the temperature control of pen cartridge storage mainly relies on external cold sources, such as ice packs or refrigeration equipment, but these methods are either bulky and not portable, or the temperature control is not precise, which can easily lead to temperature fluctuations and thus affect the activity of insulin. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies of the prior art, the present invention provides a portable insulin insulation box, which has the advantage of being able to stably store pen cartridges at low temperatures.

[0005] (II) Technical solution In order to achieve the above-mentioned purpose of being able to stably store pen cartridges at low temperatures, the present invention provides the following technical solution: a portable insulin insulation box, comprising a box body and a box cover connected to each other, and also comprising: A through slot is transversely formed in the box body and is used to store insulin pen cartridges. A semiconductor cooling chip is fixedly mounted on one end of the through slot and is blocked by a plug at the other end. The cold surface of the semiconductor cooling chip faces the plug. A supporting mechanism is arranged in the through groove and is used to support the end of the pen core; The positioning mechanism is arranged in the through groove and is used for positioning the pen core.

[0006] As a preferred technical solution of the present invention, magnetic blocks are fixedly installed at corresponding positions on the edges of the box body and the box cover.

[0007] As a preferred technical solution of the present invention, a pen slot for storing insulin pens and a needle slot for storing disposable needles are provided in the box body, and a storage interlayer for storing alcohol cotton pads is fixedly provided on the box cover.

[0008] As a preferred technical solution of the present invention, the hot surface of the semiconductor refrigeration plate is provided with a heat dissipation mechanism.

[0009] As a preferred technical solution of the present invention, the plug is threadedly connected to the end of the through groove.

[0010] As a preferred technical solution of the present invention, it also includes a temperature sensor, which is fixed in the through groove. The output end of the temperature sensor is electrically connected to a controller. The output end of the controller is electrically connected to the input ends of the semiconductor refrigeration sheet and the display screen respectively. The display screen is fixedly installed in the box body.

[0011] As a preferred technical solution of the present invention, the supporting mechanism includes an L-shaped baffle, a support spring and a support plate. An L-shaped baffle is movably arranged on the inner wall of the through groove. The L-shaped baffle is supported by a support spring. The support spring is fixedly mounted on the support plate. The support plate is fixedly mounted on the inner wall of the through groove.

[0012] As a preferred technical solution of the present invention, the positioning mechanism includes a movable plate, a traction spring and a positioning column. An inner cavity is also formed inside the box body. A movable plate is movably arranged in the inner cavity. The movable plate is pulled by the traction spring to move in the direction of the through groove. A positioning column is also fixedly installed on the side of the movable plate facing the through groove for abutting and positioning the pen core.

[0013] As a preferred technical solution of the present invention, the end of the L-shaped baffle extends into the inner cavity and forms a slope, and the end of the movable plate forms a slope coupled with the slope. The L-shaped baffle supported by the support spring can push the movable plate to move through the slope, so that it overcomes the traction force of the traction spring.

[0014] As a preferred technical solution of the present invention, a push rod is elastically and telescopically provided at the end of the plug.

[0015] (III) Beneficial effects Compared with the prior art, the present invention provides a portable insulin insulation box, which has the following beneficial effects: 1.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1: See also Figure 1-Figure 3 A portable insulin insulation box includes a box body 1 and a box cover 2 connected by a hinge. In this embodiment, Figure 1 As shown, magnetic blocks 3 are fixedly installed at corresponding positions on the edges of the box body 1 and the box cover 2. The box body 1 and the box cover 2 are connected by magnetic attraction, which is convenient for opening and closing.

[0022] like Figure 1 and Figure 2As shown, a pen slot 4 for storing insulin pens and a needle slot 6 for storing disposable needles are provided in the box body 1, and a storage interlayer 5 for storing alcohol cotton pads is fixedly provided on the box cover 2. By designing a special pen slot 4, needle slot 6 and storage interlayer 5, accessories such as insulin pens, disposable needles and alcohol cotton pads can be classified and stored, which is convenient for quick access during use, thereby improving operating efficiency.

[0023] In addition, if Figure 3 As shown, a through slot 7 is transversely provided in the box body 1 for storing an insulin pen cartridge 10. A semiconductor cooling sheet 8 is fixedly mounted on one end of the through slot 7, and the other end is blocked by a plug 9, with the cold surface of the semiconductor cooling sheet 8 facing the plug 9. The refill 10 is stored in the through slot 7, and the temperature in the through slot 7 can be effectively controlled by the semiconductor refrigeration sheet 8, avoiding the temperature fluctuation problem of traditional ice bags and the defect of large size and unportability of refrigeration equipment, and effectively ensuring the efficacy and activity of insulin.

[0024] In order to ensure the cooling effect of the semiconductor cooling plate 8 , a heat dissipation mechanism such as a heat dissipation fin or a fan may be provided on the hot surface of the semiconductor cooling plate 8 .

[0025] In this embodiment, a temperature sensor is also provided, which is fixed in the through groove 7. The output end of the temperature sensor is electrically connected to the controller. The output end of the controller is electrically connected to the input end of the semiconductor cooling sheet 8 and the display screen 11 respectively. The display screen 11 is fixedly installed in the box body 1. The temperature in the through slot 7 can be monitored in real time by the temperature sensor, and the temperature data can be transmitted to the controller. The controller can display the temperature on the display screen 11 for the convenience of the user. On the other hand, the controller can adjust the cooling power of the semiconductor refrigeration sheet 8 according to the temperature data, so as to achieve the purpose of accurate temperature control and stabilize the temperature in the through slot 7. In addition, a temperature sensor may be installed on the inner wall of the pen slot 4 to monitor the temperature of the insulin pen storage environment to prevent the temperature from exceeding 30°C; if the temperature of the pen slot 4 is too high, or the temperature in the through slot 7 fluctuates, the controller can promptly generate an alarm to remind the user; In this embodiment, the box body 1 and the box cover 2 are both made of heat-insulating materials, which can maintain a relatively low temperature in the box body 1 in summer; a connecting groove (which can be closed, for example, by blocking it with a plug plate) can also be opened to connect the through groove 7 and the pen slot 4, and the pen slot 4 can be cooled by using the cooling of the semiconductor refrigeration sheet 8. After cooling, the connecting groove can be closed and the box cover 2 can be covered, which not only achieves the cooling of the pen slot 4, but also does not affect the constant temperature in the through groove 7.

[0026] The specific circuit structure can be constructed by those skilled in the art according to actual needs, and will not be described in detail in this embodiment; the specific power supply method can also be set according to actual needs, for example, a battery can be used for power supply, and charging interfaces of multiple specifications can be set, which can be used for home charging or car charging.

[0027] In this embodiment, the plug 9 is threadedly connected to the end of the through groove 7 to block the end of the through groove 7 , which not only has a heat preservation effect, but also prevents the pen core 10 from falling off from the through groove 7 .

[0028] Embodiment 2: See also Figure 3-Figure 6 On the basis of the first embodiment, in this embodiment, a supporting mechanism is further provided in the through groove 7 for supporting the end of the refill 10, specifically, as Figure 4 As shown, the supporting mechanism includes an L-shaped baffle 12, a supporting spring 13 and a supporting plate 14. An L-shaped baffle 12 is movably provided on the inner wall of the through groove 7. The L-shaped baffle 12 is supported by the supporting spring 13. The supporting spring 13 is fixedly mounted on the supporting plate 14. The supporting plate 14 is fixedly mounted on the inner wall of the through groove 7. When the pen core 10 is placed in the through groove 7, the pen core 10 can be supported by the L-shaped baffle 12 to prevent it from contacting the semiconductor refrigeration sheet 8.

[0029] In order to further position the refill 10, as Figure 6 As shown, a push rod 22 is elastically and telescopically provided at the end of the plug 9. Specifically, the push rod 22 is fixedly mounted on a pressure plate 23. The pressure plate 23 is movably arranged in a cavity in the plug 9 and supported by a buffer spring 24. When the plug 9 is screwed on, the push rod 22 can tighten a number of pen cores 10, and the pen cores 10 are positioned between the push rod 22 and the L-shaped baffle 12 (through the tightening force, the L-shaped baffle 12 will compress the support spring 13).

[0030] like Figure 4 As shown, a force-sensitive sensor 16 is fixedly mounted on the support plate 14, and a pressure rod 15 for triggering the force-sensitive sensor 16 is mounted on the L-shaped baffle 12. When the pen core 10 is positioned between the push rod 22 and the L-shaped baffle 12, the L-shaped baffle 12 will also trigger the force-sensitive sensor 16 by moving with the help of the pressure rod 15. The output end of the force-sensitive sensor 16 is electrically connected to the controller. When the force-sensitive sensor 16 is triggered, the signal is transmitted to the controller, and the controller automatically controls the operation of the semiconductor cooling sheet 8. On the contrary, when the force-sensitive sensor 16 is not triggered, it means that there is no pen core 10 in the pen slot 4 at this time, and the controller controls the semiconductor cooling plate 8 to stop running to save power.

[0031] In the present invention, a positioning mechanism is also provided for further positioning the pen core 10, specifically, as Figure 3 , Figure 4 and Figure 5 As shown, the positioning mechanism includes a movable plate 18, a traction spring 20 and a positioning column 21. An inner cavity is also formed inside the box body 1. The movable plate 18 is movably arranged in the inner cavity. The movable plate 18 is pulled by the traction spring 20 to move toward the through groove 7. A positioning column 21 is also fixedly installed on the side of the movable plate 18 facing the through groove 7 for abutting and positioning the pen core 10. Two groups of movable plates 18 are provided. When the two groups of movable plates 18 are pulled close to each other by the traction spring 20, the two groups of positioning columns 21 can abut and position the pen core 10 to maintain the radial position of the pen core 10 in the through groove 7.

[0032] Further, such as Figure 4 As shown, the end of the L-shaped baffle 12 extends into the inner cavity and is formed with an inclined surface 17, and the end of the movable plate 18 is formed with a slope 19 coupled with the inclined surface 17. The L-shaped baffle 12 supported by the support spring 13 can push the movable plate 18 to move through the inclined surface 17 to overcome the traction force of the traction spring 20. When the L-shaped baffle 12 is pushed to move, the pressing of the inclined surface 17 is lost, and the movable plate 18 will move toward the through groove 7 under the traction force of the traction spring 20 to position the pen core 10; Thus, when the plug 9 is screwed on and the refill 10 is positioned between the ejector rod 22 and the L-shaped baffle 12, the positioning post 21 can also automatically extend to position the refill 10 in the radial position in the through groove 7; Through the spring-type design, the above positioning can also be applicable to refills 10 of different sizes.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
