Description

Technical Field

[0001] The invention relates to the technical field of cooling patches, and in particular to a recyclable safe cooling patch. Background Art

[0002] The antipyretic patch is a fever-reducing tool frequently used by patients with fever. Fever in children is a common symptom of pediatric diseases. The normal body temperature of children is usually measured by a rectal temperature of 36.5-37.5℃ and an axillary temperature of 36-37℃. Under normal circumstances, the axillary temperature is 0.2-0.5℃ lower than the oral temperature (sublingual), and the rectal temperature is about 0.5℃ higher than the axillary temperature. If the axillary temperature exceeds 37.4℃ and the temperature fluctuates by more than 1℃ during the day, it can be considered as a fever. The antipyretic patch has the effect of reducing fever and cooling down, and can relieve the pain and heat symptoms caused by fever, headache, toothache, sun exposure, and muscle sprains associated with colds. It has the effect of reducing fever and cooling down, and can relieve the pain and heat symptoms caused by fever, headache, toothache, sun exposure, and muscle sprains associated with colds.

[0003] The existing cooling patches mainly achieve physical cooling through water evaporation and gel heat absorption. In actual use, the effect of each cooling patch lasts about 6 to 8 hours. Beyond this time range, the cooling effect will gradually decrease and disappear. At the same time, using it for too long may cause skin discomfort. In order to ensure the cooling effect and further improve the applicability of the skin, a reusable safe cooling patch is proposed. There are two types of cooling patches, rectangular and round, which can be used to cool the patient's forehead, neck, armpits and other high-fever areas as needed, and a circulating cooling structure is provided, so that the cooling patch can exchange and dissipate heat for a long time to ensure the heat exchange effect. The cooling patch is composed of a fiber material mixed with 70% bamboo fiber and 30% polyester, thereby improving the antibacterial property and retaining the moisture absorption and quick-drying function. The cooling patch is easy to disassemble and replace as a whole, so that it can be quickly replaced after absorbing sweat, thereby ensuring comfort and preventing skin sweat eczema. Summary of the invention

[0004] The present invention provides a reusable safe cooling patch, which solves the problems raised in the above-mentioned background technology and can perform long-term cyclic cooling treatment on the high-fever parts of the patient, thereby ensuring the cooling effect. The composite fiber material is used as a whole, which has antibacterial properties while retaining the moisture absorption and quick-drying function, making the patient more comfortable when applying the patch. The cooling patch is easy to disassemble, assemble and replace, thereby facilitating cleaning.

[0005] The solution of the present invention to solve the above technical problems is as follows: a recyclable safe cooling patch, comprising a rectangular cooling patch, a round cooling patch, and a circulating water tank, wherein the circulating water tank is fixedly installed with a semiconductor cooling sheet, the cooling surface of the semiconductor cooling sheet is evenly fixedly installed with a heat dissipation fin, the inner wall of the circulating water tank is evenly fixedly installed with a partition plate, the inner wall of the circulating water tank is provided with a water flow channel through the heat dissipation fin and the partition plate, the circulating water tank is installed with a temperature detector and a micro water pump, and the micro water pump is fixedly connected with a water pump pipe and a drainage main pipe , the circulating water tank is fixedly connected with a return main pipe, the drainage main pipe is evenly fixedly connected with a branch drainage pipe, the return main pipe is evenly fixedly connected with a branch return pipe, the branch drainage pipes and the branch return pipes are respectively sleeved with pipe sleeves, the pipe sleeves are fixedly installed with card covers, the rectangular cooling patch and the circular cooling patch are both installed with hot water exchange pipes, the two ends of the hot water exchange pipes are respectively connected with the branch drainage pipes and the branch return pipes, the rectangular cooling patch and the circular cooling patch are both installed with joints corresponding to the card covers, and the rectangular cooling patch and the circular cooling patch are both bonded with a cooling gel layer;

[0006] The method of use includes the following steps:

[0007] S1: Connect the joints of the rectangular cooling patch and the circular cooling patch with the card cover, and the branch drain pipe and the branch return pipe can be inserted into the hot water exchange pipe. The branch drain pipe and the branch return pipe are both provided with an annular rubber ring to ensure the sealing of the connection, so that the branch drain pipe and the branch return pipe are connected with the hot water exchange pipe. Start the micro water pump to pump the coolant through the water pump pipe through the drain main pipe and the branch drain pipe into the hot water exchange pipe of the rectangular cooling patch. The coolant can be guided back to the circulating water tank through the branch return pipe and the return main pipe, so that the coolant can be recycled;

[0008] S2: The semiconductor refrigeration sheet can cool the coolant in the circulating water tank, and the temperature detector can monitor the cooling temperature. The circulating water tank forms a water flow channel through the heat dissipation fins and the partition plate, so that the coolant can be quickly cooled in the curved water flow channel. The coolant can circulate in the heat exchange water pipes of the rectangular cooling patch and the circular cooling patch, so that the rectangular cooling patch and the circular cooling patch can maintain the cooling effect;

[0009] S3: The outer wall of the rectangular and circular cooling patches is provided with a cooling gel layer. The cooling gel layer can be adhered to the skin by tearing off the PE isolation film. The rectangular cooling patch can be pasted on the forehead, and the circular cooling patch can be pasted on the neck, armpits and other high-temperature parts. The rectangular and circular cooling patches are selected in appropriate sizes according to the patient's body shape. The cooling liquid circulating in the heat exchange water pipe can perform cyclic heat exchange and cooling on the pasted parts;

[0010] S4: After the rectangular cooling patch and the round cooling patch have been used for a long time, the rectangular cooling patch can be removed from the skin, the cooling gel layer can be torn off and removed from the card cover, so that a new rectangular cooling patch and a new round cooling patch can be replaced for use. The rectangular cooling patch and the round cooling patch can then be cleaned so that a new cooling gel layer can be adhered and recycled again.

[0011] Based on the above technical solution, the present invention can also be improved as follows.

[0012] Furthermore, the rectangular cooling patch and the round cooling patch are both made of a mixture of 70% bamboo fiber and 30% polyester. The natural bamboo fiber and the polyester fiber are spun into single yarns respectively and then twisted together to form composite yarns, which are then spun to make the cooling patch. Such a cooling patch material combines the moisture absorption of cotton and the strength of polyester, so that the cooling patch can ensure the sweat absorption effect while having better strength.

[0013] Furthermore, the cooling gel layer is cross-linked by sodium alginate (2%), glycerol (5%), menthol (1%), and deionized water (92%). The cooling gel layer made of such pure natural rubber can ensure adhesion and moisturizing properties while having better safety, thereby reducing discomfort when it fits against the skin.

[0014] Furthermore, the heat exchange water pipe is laid uniformly on the inner walls of the rectangular cooling patch and the circular cooling patch according to their shapes, and the heat exchange water pipe is tightly bonded to the inner walls of the rectangular cooling patch and the circular cooling patch through adhesive, so that the heat exchange water pipe in the rectangular cooling patch can evenly exchange heat for the skin contact area.

[0015] Furthermore, a clamping block is fixedly mounted on the inner wall of the clamping cover, and a clamping groove is provided in the connector corresponding to the clamping block, so that the clamping cover can be tightly clamped with the connector.

[0016] Furthermore, the cooling gel layer is provided with a PE isolation film, which can protect the cooling gel layer and prevent it from being dirty or stale and affecting its use.

[0017] Furthermore, the circulating water tank is fixedly connected to a liquid replenishing tube, and the liquid replenishing tube is threadedly connected to a sealing cap, and the sealing cap can be unscrewed to replenish the interior through the liquid replenishing tube.

[0018] Furthermore, the branch drain pipe and the branch return pipe can be inserted into the hot water exchange pipe. The branch drain pipe and the branch return pipe are fixedly installed with annular rubber rings, which are placed at the connection between the branch drain pipe and the branch return pipe and the hot water exchange pipe, thereby ensuring a tight connection while ensuring a sealing effect.

[0019] The beneficial effects of the present invention are as follows: the present invention provides a recyclable safe cooling patch, which has the following advantages:

[0020] 1. Such cooling patches are provided in two types: rectangular and round. They can be used to cool down the patient's forehead, neck, armpits and other high-fever areas as needed. The round cooling patch can be used to dissipate heat in small areas such as the armpit and neck, while the rectangular one can be used for large areas such as the forehead, and has better applicability.

[0021] 2. A circulating cooling structure is provided, so that the cooling patch can exchange heat and dissipate heat for a long time, ensuring the heat exchange effect;

[0022] 3. The cooling patch is made of a fiber material mixed with 70% bamboo fiber and 30% polyester, which enhances the antibacterial property and retains the moisture absorption and quick-drying function. The cooling patch is easy to disassemble and replace, so it can be quickly replaced after absorbing sweat, thus ensuring comfort and preventing skin sweat eczema;

[0023] 4. The cooling patch is made of natural fibers and natural colloids, with few added ingredients and mild properties.
