Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary devices, in particular to a cooling bag. Background Art

[0002] When treating patients with high fever, hospitals often place cooling bags on the neck, forehead, and armpits for physical cooling to help patients cool down quickly. Because the temperature of the cooling bags is relatively low, placing them directly in the above-mentioned locations will cause physical discomfort to the patients. Therefore, the common clinical ice compress is to wrap the ice bag with a treatment towel or a towel and then place it directly on the patient's neck, forehead or armpits. However, during use, due to the large temperature difference between it and the outside world, the cooling bag is affected by the outside world, resulting in poor constant temperature effect and easy to melt. During the physical cooling period, the cooling bag needs to be replaced frequently, which will increase the workload of medical staff. After the cooling bag melts into liquid, if the medical staff forgets to replace it due to work errors or busy work, the cooling effect of the cooling bag will be greatly reduced, which will affect the patient's physical cooling. In this process, the treatment towel or towel will be soaked by the water vapor released by the cooling bag and accumulate water, which will cause the patient's clothes and body to be soaked, causing discomfort to the patient. Therefore, the present application provides a cooling bag to meet the needs. Utility Model Content

[0036] like Figures 1 to 8As shown, an embodiment of the utility model provides a cooling bag, including a waterproof bag 1, which is a closed bag structure formed by pasting two pieces of waterproof cloth. A thermal insulation lining 2 is fixedly connected to the top of the waterproof bag 1, and water-blocking edge strips 4 are fixedly connected to the symmetrical two side edges of the waterproof bag 1. By setting the water-blocking edge strips 4, water droplets generated during ice compress can be absorbed to prevent the water droplets from soaking the patient's clothes, thereby improving the patient's comfort. A strap 6 is fixedly connected to the outer wall of one end of the waterproof bag 1, and the strap 6 is made of elastic fabric. A second Velcro 7 is fixedly connected to the inner surface of the end of the strap 6 away from the waterproof bag 1. A rough surface matched with the second Velcro 7 is provided on the outer wall of the end of the waterproof bag 1 away from the strap 6. By setting the strap 6, it is convenient to bind the waterproof bag 1 to the patient, to prevent the cold source from falling, and thus to facilitate the patient during ice compress. Move the body to improve the patient's comfort during ice compress. A cold storage bag 5 is fixedly connected to the top of the thermal insulation lining 2. The cold storage bag 5, as a cold source, is detachably connected to the waterproof bag 1, which is convenient for updating and replacing the cold source. At the same time, the detachable cold storage bag 5 is convenient for being put into the refrigerator for freezing and is convenient for reuse. First Velcro 3 is respectively provided on both sides of the thermal insulation lining 2. The first Velcro 3 is hot-melt connected to the waterproof bag 1. The cold storage bag 5 is detachably connected to the waterproof bag 1 through the first Velcro 3. A compensation bracket 9 is provided inside the waterproof bag 1, and the compensation bracket 9 is provided in the hollow part of the waterproof bag 1. The compensation bracket 9 can prop up the waterproof bag 1. By setting the compensation bracket 9, the gap between the cold storage bag 5 and the patient's skin after melting and shrinking can be compensated, so that the cold storage bag 5 always fits the patient's skin to maintain the best ice compress effect.

[0037] like Figure 4 and Figure 5 As shown, the water-blocking edge strip 4 is a cylindrical structure with closed ends and is made of the same material as the waterproof bag 1. The water-blocking edge strip 4 is hot-melt connected to the waterproof bag 1. A plurality of groups of water absorption holes 12 are opened on the surface of the water-blocking edge strip 4. A water absorption core 11 is arranged inside the water-blocking edge strip 4. The water absorption core 11 is a water-absorbing sponge and its structure is adapted to the water-blocking edge strip 4. The water vapor generated during the ice compress condenses on the patient's skin to form water droplets. Since the skin at the ice compress site is wrapped by the waterproof cover, waterproof bag 1 and the water-blocking edge strip 4, the rolling water droplets can be blocked. When the water droplets are concentrated at the water-blocking edge strip 4, the water absorption core 11 enters the water-blocking edge strip 4 through the water absorption holes and is absorbed by the first accommodating cavity 8 of the water absorption core, thereby preventing the water droplets from rolling onto the patient's clothes and soaking them during the ice compress, thereby further improving the patient's comfort.

[0038] like Figure 6 and Figure 7As shown, the cold storage bag 5 includes an ice pack layer 13 and a waterproof layer 14. The edges of the ice pack layer 13 and the waterproof layer 14 are pressed together to form a closed cavity. The closed cavity is filled with a cold storage layer 15. The ice pack layer 13 is made of cotton cloth, and the waterproof layer 14 is made of high-density plastic material. The cold storage layer 15 is a hydrogel. When in use, the cold storage bag 5 is placed in water, and water passes through the ice pack layer 13 and is absorbed by the cold storage layer 15. The cold storage layer 15 absorbs water and expands, and can be placed in a refrigerator or freezer for freezing. The cold storage bag after freezing 5 can be installed on the waterproof bag 1 as a cold source. When applying ice, the ice layer 13 is placed close to the patient's skin. The compensation bracket 9 includes a plurality of groups of parallel supporting cross bars 16. The two ends of the supporting cross bars 16 are respectively fixedly connected with inner buckle bars 17. The supporting cross bars 16 and the inner buckle bars 17 are an integrally formed structure. The plurality of groups of inner buckle bars 17 are fixedly connected by supporting connecting rods 18. The supporting connecting rods 18 are located at the ends of the inner buckle bars 17. A compensation bent rod 19 is welded in the middle of the supporting cross bars 16. The compensation bent rod 19 is an arched structure.

[0039] The working principle provided by the utility model is that before applying ice, the operator can remove the cold storage bag 5 from the waterproof bag 1, put it into water, let the cold storage bag 5 absorb water and swell, and then put the cold storage bag 5 after absorbing water into the refrigerator for freezing. After freezing, the cold storage bag 5 can be fixed on the waterproof bag 1 through the first Velcro 3. When installing the cold storage bag 5, it is necessary to embed the two ends of the cold storage bag 5 into the two ends of the compensation bracket 9 respectively, that is, embed the two ends of the cold storage bag 5 into the bent part of the inner buckle rod 17 respectively, so that the inner buckle rod 17 has a limiting effect on the cold storage bag 5, increasing the cold storage bag 5 is used to ensure the stability between the cold storage bag 1 and the waterproof bag 1. The whole surface of the cold storage bag 5 will be in close contact with the thermal insulation lining 2. The thermal insulation lining 2 will wrap the cold storage bag 5 as the compensation bracket 9 is bent, reducing the contact area of ​​the cold storage bag 5 with the outside air, thereby reducing the melting speed of the cold storage bag 5 and effectively extending the cold storage time of the cold storage bag 5. Then, the ice compress layer 13 is placed in close contact with the patient's affected area, and the strap 6 is passed around the appropriate part of the human body and tied to the waterproof bag 1, so that the patient can move the body during the ice compress process to avoid stiffness and numbness caused by long-term immobility, thereby improving the patient's comfort.

[0040] At the initial stage of ice compress, the pressure generated by the binding is transmitted to the compensation bracket 9, and the compensation bracket 9 is deformed under pressure, wherein the gap between the supporting cross bar 16 and the compensation bent bar 19 is reduced, and the elastic force generated by the deformation of the compensation bracket 9 is transmitted to the cold storage bag 5, so that the cold storage bag 5 is close to the patient's affected part to achieve a better ice compress effect. During the ice compress process, the cold storage bag 5 gradually melts and shrinks, and the pressure on the compensation bracket 9 gradually decreases, so that the compensation bracket 9 gradually recovers its deformation, thereby compensating for the gap between the flattened cold storage bag 5 and the patient's affected part, so that the cold storage bag 5 is always in close contact with the patient's affected part, thereby maintaining the ice compress effect.

[0041] During the ice compress process, condensed water droplets will be generated on the patient's skin, and the water droplets will roll down along the skin after gathering on the skin. Since the waterproof bag 1 is tightly attached to the patient's affected area after being bound, the water droplets will be blocked by the end of the waterproof bag 1 and the water-blocking edge strip 4, and the water droplets gathered at the water-blocking edge strip 4 will be absorbed by the water-absorbing core 11 through the water absorption holes 12. Because the waterproof water-blocking edge strip 4 wraps the water-absorbing core 11, the water droplets are prevented from continuing to roll down, and the condensed water droplets during the ice compress process are prevented from soaking the patient's clothes, thereby further improving the patient's comfort.

[0042] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
