The term "burst bag" refers to a phenomenon in which the bag body is broken, causing the first thermal storage agent to flow out.

To further clarify the objects, advantages and features of the present invention, a more particular description of the utility model will be rendered by reference to the appended drawings. It is to be noted that the drawings are in a very simplified form and are not to precise scale, which is merely for the purpose of facilitating and distinctly claiming the embodiments of the present invention. The same or similar reference numbers in the drawings identify the same or similar elements.

Fig. 1 is a schematic diagram of a medical device 10 according to an embodiment of the present invention. As shown in FIG. 1, the medical device 10 includes a dressing 100, the dressing 100 being configured as shown in FIGS. 2-4. The dressing bag 100 comprises a bag body 110, an isolation layer 120 and a first thermal storage agent 130, wherein the bag body 110 is provided with a first inner cavity 111 which is closed, the isolation layer 120 is arranged in the first inner cavity 111 and connected with the bag body 110, the first inner cavity 111 is divided into a first sub-inner cavity 111a and a second sub-inner cavity 111b, and a plurality of through holes 121 are further arranged on the isolation layer 120, so that the first sub-inner cavity 111a and the second sub-inner cavity 111b are communicated through the through holes 121. The first thermal storage agent 130 is filled in the first inner cavity 111 (i.e., the first thermal storage agent 130 is filled in the first sub-inner cavity 111a and the second sub-inner cavity 111 b).

The embodiment of the present invention does not limit the specific type of the first thermal storage agent 130, as long as it has a certain thermal insulation capability, and the selectable types include water, thermal insulation gel, and the like. When the first thermal storage agent 130 is a thermal insulation gel, the thermal insulation gel may be one or two of polyacrylamide and sodium polyacrylate, or the thermal insulation gel may be prepared by one skilled in the art according to the prior art using a thickener, an antifreeze, a preservative, and water. The heat-insulating gel can be reused, and the heat-insulating gel is not easy to crystallize at low temperature and cannot scratch the bag body 110 and the isolation layer 120.

The first thermal storage agent 130 generally has a strong fluidity. The first inner cavity 111 is partitioned by the isolation layer 120, such that a portion of the first thermal storage agent 130 is filled in the first sub-inner cavity 111a and another portion is filled in the second sub-inner cavity 111 b. That is, the isolation layer 120 divides the first inner cavity 111 with a larger space into two sub-inner cavities with a smaller space, and the two sub-inner cavities respectively accommodate a portion of the first thermal storage agent 130, so that the range of motion of each portion of the first thermal storage agent 130 can be reduced, and the flow of the first thermal storage agent 130 can be slowed down and the accumulation phenomenon can be alleviated. On the other hand, when the local area of the dressing bag 100 is subjected to the external pressure, the first thermal storage agent 130 can circulate in the first sub-inner cavity 111a and the second sub-inner cavity 111b through the through hole 121, and the flow activity of the effective fluid amount of the first thermal storage agent 130 per unit time is reduced, so that the pressure is reduced, the stress concentration is reduced, the pressure in the first sub-inner cavity 111a and the second sub-inner cavity 111b is kept balanced, and the bag explosion is reduced or even avoided. The shape of the through hole 121 is not particularly limited in the embodiments of the present invention, and may be at least one of a circular shape, a square shape, a circular waist shape, an oval shape, a polygonal shape, or an irregular shape.

It should be noted that the aperture of the through hole 121 cannot be too small, and the first thermal storage agent 130 cannot effectively circulate between the first sub-inner cavity 111a and the second sub-inner cavity 111b, so that the purpose of pressure equalization is not achieved. The aperture of the through hole 121 cannot be too large, which may cause the first thermal storage agent 130 to jump between the first sub-inner cavity 111a and the second sub-inner cavity 111b, and is also not favorable for pressure balance.

Further, a second inner cavity 101 is formed on the dressing bag 100, and the second inner cavity 101 is isolated from the first inner cavity 111. And, the medical device 10 further includes a heat conduction part 200, the heat conduction part 200 being separable from the compress bag 100 to perform a cooling process and store cold or a heat treatment and store heat, the heat conduction part 200 being further provided in the second inner chamber 101 and supplying the cold or the heat to the first thermal storage agent 130. As previously mentioned, the medical device 10 may be used to apply cold or hot compress therapy to an affected area. When medical device 10 is used for the cold compress treatment, heat-conducting portion 200 is used for to first temperature storage agent 130 provides cold volume, works as when medical device 10 is used for the hot compress treatment, heat-conducting portion 200 is used for to first temperature storage agent 130 provides the heat.

The method for cold compress treatment of the affected part by using the medical device 10 comprises the following steps: the dressing bag 100 and the heat conduction part 200 are placed in a refrigeration device such as a refrigerator to be cooled, and the first temperature storage agent 130 and the heat conduction part 200 store cold. The dressing 100 is then removed and the dressing 100 is secured to the affected area by any suitable means. Since the first thermal storage agent 130 has a short heat preservation time, if a long treatment time is required, the heat conduction portion 200 is placed in the second inner cavity 101 when the temperature of the first thermal storage agent 130 is about to return to normal temperature, and the cold stored in the heat conduction portion 200 is transferred to the first thermal storage agent 130, so that the temperature of the first thermal storage agent 130 is reduced, and the compress bag 100 can be continuously used for cold compress treatment. Compared with the conventional cold compress method, the cold compress time of the compress bag 100 is prolonged by supplementing cold to the first temperature storage agent 130 through the heat conduction part 200, so that the first temperature storage agent 130 or the compress bag 100 does not need to be replaced frequently, and the treatment process is simplified. Particularly, when the dressing bag 100 is of a wearable structure and the first thermal storage agent 130 cannot be separated from the bag body 110, the arrangement can prevent the patient from repeatedly wearing and taking off the bag body 110 in a long treatment process, so that the treatment process is simpler and more convenient.

It will also be understood by those skilled in the art that the same is true for the application of heat to the medical device 10, except that the application bag 100 and the heat conducting portion 200 are heated in a hot water or microwave oven prior to the start of the application.

In one exemplary embodiment, as shown in fig. 4, the second cavity 101 is formed using the isolation layer 120. Specifically, the bag body 110 includes a first surface layer 112 and a second surface layer 113, and the first surface layer 112, the barrier layer 120, and the second surface layer 113 are sequentially stacked in a third direction, such that a space between the first surface layer 112 and the second surface layer 113 constitutes the first inner cavity 111, a space between the first surface layer 112 and the barrier layer 120 constitutes the first sub-inner cavity 111a, and a space between the barrier layer 120 and the second surface layer 113 constitutes the second sub-inner cavity 111 b. The isolation layer 120 has first regions 102 and second regions 103 alternately arranged in a first direction, which is perpendicular to the third direction. The barrier layer 120 includes a first structural layer 122 and a second structural layer 123, wherein the first structural layer 122 is adjacent to the first skin layer 112 and is connected to the first skin layer 112, and the second structural layer 123 is adjacent to the second skin layer 113 and is connected to the second skin layer 113. In the first region 102, the first structural layer 122 and the second structural layer 123 are attached to each other, and in the second region 103, the first structural layer 122 and the second structural layer 123 are separated from each other and form the second inner cavity 101. That is, in the second region 103, the space between the first structural layer 122 and the second structural layer 123 constitutes the second inner cavity 101. In practice, the isolation layer 120 may be produced using an integral hot press molding process.

Preferably, the number of the first regions 102 is one more than that of the second regions 103, and then the number of the second regions 103 is equal to that of the second cavities 101, and each of the second cavities 101 is located between two of the first regions 102. When the heat conduction portion 200 is disposed in the second inner cavity 101, the heat conduction portion 200 supports the walls of the second inner cavity 101 (i.e., the portions of the first structural layer 122 and the second structural layer 123 at the second region 102) such that the first sub-inner cavity 111a is divided into at least two portions arranged in the first direction (each portion corresponds to the first region 102), and the second sub-inner cavity 111b is also divided into at least two portions arranged in the first direction. This has the advantage of further dividing the first inner cavity 111, so that the first thermal storage agent 130 located in any part of the first sub-inner cavity 111a and the second sub-inner cavity 111b has a smaller moving range, slows down the flow, avoids the accumulation, and the volume of the first sub-inner cavity 111a and the second sub-inner cavity is fixed, so that the volume of the first thermal storage agent 130 contained therein is fixed, which is beneficial to improving the distribution uniformity of the first thermal storage agent 120 in the first inner cavity 111.

In the present embodiment, it can be understood by those skilled in the art that the through hole 121 is disposed in the first region 102 to ensure that the second inner cavity 101 and the first inner cavity 111 are isolated from each other. Furthermore, it is preferable that one elongated through hole 121 (including any one of a rectangle, a oval, and an ellipse) is disposed at each first region 102, and the through hole 121 extends along a second direction perpendicular to the first direction and the third direction. Further, in any of the first regions 102, the area of the through hole 121 occupies about 1/5 of the area of the first region 102. In more detail, the size of the through hole 121 in the first direction is 5mm to 10mm, and the distance between the through hole 121 and the edge of the bag body 110 in the second direction is 5mm to 10 mm.

Referring back to fig. 1, the shape of the heat conducting portion 200 matches the shape of the second cavity 101. For example, when the second inner cavity 101 is an elongated cavity, the heat conducting portion 200 is a long rod-shaped structure. Generally, the material of the heat conducting part 200 has good heat conductivity and/or has a certain heat retaining property. Alternatively, the heat conduction part 200 may be a metal component, such as a stainless steel rod, or the heat conduction part 200 includes a rod-shaped first base (not shown in the figure) having a sealed third inner cavity filled with a second thermal storage agent, which may include a thermal insulation gel.

Preferably, the second lumen 101 extends in the second direction. When the medical device 10 is used for treating a certain part such as an arm or a leg, the dressing 100 can be bent and attached to the skin of the part so that the second direction extends in the longitudinal direction of the arm or the leg without interfering with the use of the heat conductive portion 200.

With continued reference to fig. 1 in conjunction with fig. 2 and 4, the medical device 10 further includes a temperature monitoring unit 300, wherein the temperature monitoring unit 300 is configured to monitor and display the temperature of the first thermal storage agent 130. The temperature monitoring unit 300 may enable a user to intuitively and accurately obtain the current temperature of the first thermal storage agent 130, so that the user can supplement the cold or heat to the first thermal storage agent 130 in time by using the heat conduction part 200.

Optionally, the temperature monitoring unit 300 comprises a temperature measuring end 310 and a display end 320 which are connected with each other, wherein the temperature measuring end 310 is arranged in the first inner cavity 111 and is in contact with the first thermal storage agent 130 to obtain the temperature of the first thermal storage agent 130, and the display end 320 is arranged outside the dressing bag 100 and displays the temperature of the first thermal storage agent 130. In a specific implementation, the temperature monitoring unit 300 is a color-changing thermal chip configured to display a first predetermined color when the temperature of the first thermal storage agent 130 is lower than a preset temperature, and display a second predetermined color when the temperature of the first thermal storage agent 130 is higher than the preset temperature. Thus, a part of the color-changing temperature-sensing chip is the temperature measuring terminal 310, and the other end of the color-changing temperature-sensing chip is the display terminal 320. The preset temperature is set according to actual needs, and may be a temperature slightly lower than normal temperature. In this embodiment, the color-changing temperature sensing chip includes a second substrate and a reversible temperature-changing material disposed on the second substrate, where the reversible temperature-changing material may be any one of the prior arts, including but not limited to iodides, complexes, double salts of Ag, Cu, and Hg, and compounds formed by cobalt salts, nickel salts, and hexamethylenetetramine.

In addition, in the embodiment of the present invention, the bag body 110 and the isolation layer 120 may be made of PVC material, which has the advantages of good flexibility, strong ductility and extrusion resistance. More specifically, the edges of the first surface layer 112, the isolation layer 120 and the second surface layer 113 are connected and sealed by a high-frequency hot-press fusion technology, so that the edges of the dressing bag are firm and do not foam, and the service life of the dressing bag 100 is further prolonged.

Although the present invention is disclosed above, it is not limited thereto. Various modifications and alterations of this invention may be made by those skilled in the art without departing from the spirit and scope of this invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
