Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-4As shown, this utility model provides a technical solution: a multi-purpose self-cooling medical ice pack, including an ice pack body 1, the ice pack body 1 including a first ice pack 2 and a second ice pack 3, the first ice pack 2 and the second ice pack 3 are fixedly connected at one end along their width direction and at both ends along their length direction, and a break line 4 is provided at the connection point at both ends of the first ice pack 2 and the second ice pack 3 along their length direction, and the other end of the first ice pack 2 and the second ice pack 3 along their width direction is connected by a self-sealing strip.

[0018] A sterile gauze 5 is placed between the first ice pack 2 and the second ice pack 3. The sterile gauze 5 makes it easy to wrap the first ice pack 2 and the second ice pack 3 when using them, so as to sterilely cover the area that needs to be iced.

[0019] like Figure 3-4 As shown, the self-sealing strip includes a sub-seal 6 and a mother seal 7. The sub-seal 6 is embedded inside the mother seal 7 to form a mechanical seal. The self-sealing strip seals the self-sealing bag structure formed by the first ice pack 2 and the second ice pack 3. It is suitable for temporary placement and transfer of specimens, storage and transportation of severed fingers and limbs, and other scenarios.

[0020] The first ice pack 2 and the second ice pack 3 both include an inner bag and an outer bag, with the inner bag located in the middle of the outer bag. The inner bag is filled with refrigerant, and the outer bag is filled with water. By squeezing the inner bag, the refrigerant and water are mixed and reacted, thereby rapidly lowering the temperature of the first ice pack 2 and the second ice pack 3, thus achieving ice application.

[0021] like Figure 1 As shown, the front surface of the ice pack body 1 is coated with a writing film layer 8, which facilitates the recording of information. The writing film layer 8 is a PET film or a matte PP film.

[0024] Working principle: When in use, the inner bag is broken by external force, causing the refrigerant to mix and react with water, thereby rapidly lowering the temperature of the first ice pack 2 and the second ice pack 3. Specimens, severed fingers, limbs, and other objects requiring temporary storage and transport are then placed between the first ice pack 2 and the second ice pack 3 in their closed state. The sub-seal 6 is then inserted into the mother seal 7, closing the opening between the first ice pack 2 and the second ice pack 3. The self-sealing bag structure formed by the first ice pack 2, the second ice pack 3, and the self-sealing strip allows for temporary storage and transport of specimens, severed fingers, limbs, etc. When emergency large-area cooling is required, the opening between the first ice pack 2 and the second ice pack 3 is opened, and the connection points on the left and right sides of the first ice pack 2 and the second ice pack 3 are torn along the tear line 4. The unfolded cold compress structure formed by the first ice pack 2 and the second ice pack 3 can then be used to wrap and cool the area. It can be used in multiple scenarios and is convenient to use.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
