Description

Technical Field

[0001] The invention relates to the technical field of medical constant temperature patches, in particular to a constant temperature patch for flushing liquid. Background Art

[0002] Medical flushing fluid is mainly used to flush and moisten wounds, incisions, ulcers, abrasions, burns and other wounds. It can not only quickly control infection, but also indirectly promote blood circulation around the wound and promote healing. It is suitable for burns, general surgery, emergency department, orthopedics, dermatology, endocrinology, anorectal, urology, gynecology, dressing room, etc. When flushing the wound of the patient with flushing fluid, the flushing fluid is usually heated to a temperature of about 25-30°C, which will not affect the cold stimulation of the patient and make the patient the most comfortable state. At present, most of the medical flushing fluids supplied on the market are bagged and disposable. When cleaning the patient's wound, basically a bag will be used up in a few hours, which is very convenient. Hot water is used to heat the bagged flushing fluid before use, but after heating with hot water, the flushing fluid is difficult to maintain a constant temperature.

[0003] To achieve the above purpose, the technical personnel in this field usually put the bagged flushing liquid into a water bath heating device for constant temperature treatment during use. However, after the existing bagged flushing liquid is heated in a water bath, it is usually hung at a certain height for use, and the wound surface is flushed by the height difference of the liquid level. In order to keep the flushing liquid at an optimal and comfortable temperature, the medical staff must constantly repeat the constant temperature treatment, which will cause unnecessary trouble to the medical staff. In order to keep the temperature of the flushing liquid for several hours, it is of great significance to provide the flushing liquid with a self-heating constant temperature protection device so that the medical staff can use the flushing liquid conveniently. Summary of the invention

[0004] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a constant temperature patch for flushing liquid, which controls the heat generated by the self-heating layer to prevent it from dissipating outward, and self-heats and keeps the flushing liquid warm for several hours, which is convenient for medical staff to use.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme, a constant temperature patch for flushing liquid, comprising:

[0006] Self-heating layer;

[0027] In order to enable those skilled in the art to better understand and implement the technical solution of the present invention, the present invention is further described below in conjunction with specific embodiments and drawings, but the embodiments are not intended to limit the present invention.

[0028] Example 1

[0029] A constant temperature patch for flushing liquid, see Figure 1 As shown, including:

[0030] Self-heating layer 2: The self-heating layer is made of iron powder, activated carbon, vermiculite, water-absorbing material and water as raw materials. The total thickness of the self-heating layer is set to 2-4 mm according to the needs. The thickness also has a certain effect on the duration of heat generation of the self-heating layer. According to experience, the self-heating layer is set to 2-4 mm, which is just enough to ensure the temperature of each bag of flushing liquid before use;

[0031] The adhesive layer 22 is arranged on the inner surface of the self-heating layer 2, so that the self-heating layer 2 adheres to the surface of the flushing fluid bag 1; the adhesive layer is processed into a rectangle as needed, and adhered to the surface of the flushing fluid bag by winding, so that the adhesive layer can just adhere to the surface of the flushing fluid bag, which is convenient for directly heating the flushing fluid; the provided flushing fluid constant temperature patch is flexible to use, and constant temperature patches of different specifications can be produced according to the size of the flushing fluid bag, which is convenient for medical staff to use.

[0032] The thermal insulation layer 21 is arranged on the outer surface of the self-heating layer 2 and is provided with a plurality of air holes 23. The thermal insulation layer can insulate the heat generated by the self-heating layer to prevent it from being transmitted outward, and can effectively maintain the temperature of the flushing liquid for several hours, thereby ensuring the required temperature during the use of each bag of flushing liquid; wherein, the material used for the thermal insulation layer is aerogel thermal insulation material, and its thickness is 3 to 5 mm.

[0033] In addition, a protective film is provided on the surface of the insulation layer. When it is not in use, the main function of the protective film is to prevent air from entering. When it is in use, the protective film is torn off to ensure that air enters the self-heating layer.

[0034] To this end, this embodiment is based on a self-heating material, and an adhesive layer is provided on its inner surface, so that the self-heating layer adheres to the surface of the bag containing the flushing liquid, and can heat the bag containing the flushing liquid more directly. By providing an insulating layer on its outer surface and multiple air holes on it, during use, air passes through the air holes, and generates heat after contacting the self-heating material to heat it, thereby effectively heating the flushing liquid. The insulating layer can effectively maintain the temperature of the flushing liquid for several hours.

[0035] Example 2

[0036] A constant temperature flushing liquid patch, based on Example 1, see Figure 2 As shown, the longitudinal section of each vent hole 23 is conical, so that the inner port diameter of each vent hole 23 is smaller than the outer port diameter, which can facilitate air entry, but prevent the heat generated by the self-heating layer from dissipating from the vent hole.

[0037] In order to further prevent the heat generated by the self-heating layer from being dissipated from the air holes, each air hole 23 is further provided with:

[0038] The grille mesh 231 is horizontally arranged at the inner side port of the air vent 23, and the circumferential edge of each grille mesh 231 is connected to the inner edge of the inner side port of the air vent 23;

[0039] The reflecting part 233 is arranged in the air vent 23, and is used to prevent the internal airflow from diffusing outwards; specifically, the reflecting part 233 is arranged as an umbrella-shaped reflecting plate, and a gap is reserved between the edge of the reflecting plate and the inner wall of the air vent 23, and the central axis of the reflecting plate and the central axis of the air vent 23 are the same center axis, which further prevents the heat generated by the self-heating layer from being dissipated from the air vent, and can effectively prevent the hot air generated inside from diffusing outwards from the air vent, and further effectively maintain the temperature of the flushing liquid for several hours;

[0040] The connecting portion 232 is used to connect the grille mesh 231 and the reflecting portion 233. To this end, one end of the connecting portion 232 is vertically connected to the center of the grille mesh 231, and the other end of the connecting portion 232 is fixedly connected to the center of the reflecting plate. The connecting portion 232 supports the umbrella-shaped reflecting plate so that the plane of the reflecting plate is parallel to the plane of the grille mesh, so that the reflecting plate effectively prevents the heat generated inside from diffusing outward from the air vents.

[0041] Example 3

[0043] The heat conduction layer is arranged between the self-heating layer 202 and the adhesion layer 22. The material used for the heat conduction layer is graphene, and its thickness is 1 to 2 mm, which is conducive to the heat generated by the self-heating layer to be evenly transferred to the surface of the flushing liquid bag, so that the flushing liquid is heated evenly and uneven heat is avoided.

[0044] In summary, the constant temperature patch for flushing liquid provided in Examples 1 to 3 is based on a self-heating material, and an adhesive layer is provided on its inner surface, so that the self-heating layer adheres to the surface of a bag containing flushing liquid, and can heat the bag containing flushing liquid more directly. By providing an insulating layer on its outer surface and a plurality of air holes thereon, during use, air passes through the air holes, and generates heat after contacting the self-heating material to heat it, thereby effectively heating the flushing liquid, and the insulating layer can effectively maintain the temperature of the flushing liquid for several hours.

[0045] In addition, each of the air holes is also provided with a reflective portion, which can effectively prevent the hot air generated inside from diffusing outward from the air holes, and further effectively maintain the temperature of the flushing liquid for several hours.
