[0017] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. The present invention is described in more detail by way of example with reference to the accompanying drawings in the following paragraphs. It should be noted that the accompanying drawings are all in a very simplified form and are not in precise proportions, and are only used to facilitate and clearly assist in explaining the purpose of the embodiments of the present invention.
[0018] See also Figures 1-2 In an embodiment of the present invention, an adjustable cooling ice bag includes two symmetrically arranged hand-shaped ice bags 6, the two hand-shaped ice bags 6 are connected to each other by two connecting belts 8, the opposite side walls of the two hand-shaped ice bags 6 are connected to each other by two elastic belts 9, and a hand strap 7 is provided on the side wall of each hand-shaped ice bag 6. Each hand-shaped ice bag 6 is formed by bonding and fixing a first cold fabric layer 1, a first waterproof layer 2, a cold storage layer 3, a second waterproof layer 4, and a second cold fabric layer 5 in sequence from top to bottom. The first cold fabric layer 1 and the second cold fabric layer 5 are both 3 0-silk Polyester cold-sensing fabric is soft and breathable, ensuring that no irritation or discomfort is caused to the skin during the cold compress process; the first waterproof layer 2 and the second waterproof layer 4 are composite films of PE and DET, which are used to prevent condensed water from seeping out and keep dry, while avoiding contamination of clothes or sheets; the hand strap 7 is an elastic and adjustable strap, and by adjusting the length or tightness of the hand strap 7, the hand-shaped ice pack 6 can be more stably fixed on the hand, making it convenient to hold the hand-shaped ice pack 6 for cold compressing the skin.
[0019] The cold storage layer 3 is composed of a hand-shaped covering bag and a cold storage agent filled in the covering bag; The weight components of the cold storage agent include 5%-8% thickening gelling agent, 3%-5% modified nano alumina particles, 75%-85% water, and 12%-15% antifreeze agent (preferably, the weight components of the cold storage agent include 6% thickening gelling agent, 4% modified nano alumina particles, 77% water, and 13% antifreeze agent), wherein the modified nano alumina particles are gamma phase nano alumina particles with polyacetal grafted on the surface, the thickening gelling agent is selected from at least one of sodium polyacrylate, sodium alginate, sodium hydroxymethyl cellulose, and chitosan, and the antifreeze agent is ethylene glycol.
[0020] The preparation method of the coolant is as follows: The first step is to weigh the thickening gelling agent, modified nano-alumina particles and antifreeze agent according to the weight components, and mix the above materials evenly for later use; In the second step, the mixture prepared in the first step is added into water to prepare a mixed solution; The third step is to leave the solution in the second step to stand for 8 hours to obtain a cooling agent for ice packs.
[0021] Test of the performance of the refrigerant: The DSC test of the preferably prepared refrigerant showed that the phase change temperature of the refrigerant was -9.54°C and the latent heat of phase change was 428.6 kj / kg.
[0022] The above-mentioned coolant contains gamma-phase nano-alumina particles with polyacetal grafted on the surface. The gamma-crystalline phase nano-alumina particles have a high surface area and activity, and can form a stably dispersed alumina nanofluid by interacting with the molecules in the thickening gelling agent. The gamma-phase alumina nanofluid has a high thermal conductivity and latent heat of phase change, which can increase the cold storage capacity. At the same time, the polyacetal grafted on the surface of the gamma-phase nano-alumina particles can establish a steric hindrance stabilization layer on the surface of the particles, which can reduce the cooling rate of the ice bag.
[0023] During use, the user can easily put the ice bag into the freezer of the refrigerator for pre-cooling. After taking it out, the two hand-shaped ice bags 6 can be tied to both hands through the hand straps 7 for use. The combination of the ice bag with a hand-shaped structure design and the high-efficiency coolant enables the product to provide an efficient and comfortable cold compress effect. The hand-shaped ice bag 6 can better fit various parts of the patient because of its hand shape. In addition, when cold compresses are needed on two tonsils, the two hand-shaped ice bags 6 can also be put on the neck through the elastic band 9, so that after the hand-shaped ice bag 6 is placed on the cold compress area, it can be elastically tied through the elastic band 9 without being held in the hand, which is very convenient.
[0024] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
