Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a heat therapy pad for uterine care. Background Technology

[0002] Currently, many patients in the reproductive medicine department need to undergo egg retrieval surgery or suffer from ovarian hyperstimulation syndrome. After the surgery, they need to apply heat to the ovarian area to relieve discomfort. However, most existing heat packs only control the temperature, which can cause the local temperature to be too high. The ovaries are easily stimulated by the high temperature, which is not conducive to the patient's recovery. Summary of the Invention

[0003] To address the above problems, this utility model provides a heat therapy pad for uterine care.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a heat therapy pad for uterine care, comprising a pad body, wherein a trapezoidal heating zone with an upper bottom edge length shorter than the lower bottom edge length is provided in the middle of the pad body, the heating zone comprising at least one first heating film and at least two second heating films, the first heating film being located in the middle and upper part of the heating zone, and the second heating film being provided on both the left and right sides of the lower part of the heating zone, both the first and second heating films having etching grooves, the etching grooves being arranged in a radial spiral, the groove width of the first heating film etching groove being greater than the groove width of the second heating film etching groove, the spiral spacing of the first heating film etching groove being greater than the spiral spacing of the second heating film etching groove, and a wire being connected to the outermost end of the etching groove, the wire being connected to a controller.

[0005] Preferably, the heating zone has a groove in the middle, and the bottom of the groove is larger than the lower half of the first heating film.

[0006] Preferably, the pad includes a heat insulation layer, an aluminum foil heat-equalizing layer, a heating film layer, a silicone buffer layer, and a surface antibacterial layer, which are stacked and glued together in sequence. The surface antibacterial layer is located at the bottom and contacts the skin, while the heat insulation layer is located at the top and contacts the environment.

[0007] Preferably, a temperature sensor is provided between the first heating film and the second heating film.

[0008] Preferably, the pad body has a fixing strap on its side, the free end of the fixing strap is fixed with a hook and loop fastener, and the top surface of the pad body is fixed with a hook and loop fastener on the side away from the fixing strap.

[0009] Preferably, the thickness of the heat insulation layer is 1.5~2mm, the thickness of the aluminum foil heat-equalizing layer is 0.05~0.1mm, the thickness of the heating film layer is 0.2~0.3mm, the thickness of the silicone buffer layer is 2~3mm, and the thickness of the surface antibacterial layer is 0.5~1mm.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses a heating film for heating, resulting in uniform heat distribution and no risk of electromagnetic interference. The different spiral spacing and groove width of the etching grooves cause different resistances of the heating film. The spiral spacing and groove width of the first heating film etching groove are both greater than those of the second heating film etching groove, making the resistance of the first heating film greater than that of the second heating film. This results in the temperature of the first heating film being lower than that of the second heating film, and the temperature of the ovarian area being lower than that of other areas, avoiding direct high-temperature stimulation of the ovary, alleviating postoperative discomfort for the patient, and promoting local blood circulation. The heating area is divided into multiple independent temperature zones, which can adapt to the heat needs of different parts of the abdomen. The heating zone is trapezoidal and extends to the iliac vessel area, promoting pelvic collateral circulation and avoiding the sensitive area directly corresponding to the ovary. The grooves prevent the pad from completely covering the ovary, avoiding compression of the ovary after egg retrieval. Attached Figure Description

[0016] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0017] Please refer to the reference. Figure 1A heating pad for uterine care according to an embodiment of the present invention includes a pad body 1. The pad body 1 has a trapezoidal heating zone 2 in the middle, with the upper bottom edge being shorter than the lower bottom edge. The heating zone 2 includes at least one first heating film 21 and at least two second heating films 22. The first heating film 21 is located in the middle and upper part of the heating zone 2. The second heating film 22 is provided on both the left and right sides of the lower part of the heating zone 2. Both the first heating film 21 and the second heating film 22 are provided with etching grooves 29. The etching grooves 29 are arranged in a radial spiral. The groove width of the first heating film 21 is greater than the groove width of the second heating film 22. The spiral spacing of the first heating film 21 etching grooves 29 is greater than the spiral spacing of the second heating film 22 etching grooves 29. The outermost end of the etching groove 29 is connected to a wire 41, and the wire 41 is connected to a controller 4.

[0018] The trapezoidal heating zone 2 extends to the iliac vessels on both sides, enhancing heat coverage; heating is achieved through a heating film, ensuring uniform heat distribution and eliminating the risk of electromagnetic interference; the different spiral spacing and width of the etching grooves result in different resistances of the heating film. The spiral spacing and width of the etching groove 29 of the first heating film 21 are both greater than those of the etching groove 29 of the second heating film 22, making the resistance of the first heating film 21 higher than that of the second heating film 22. This results in the temperature of the first heating film 21 being lower than that of the second heating film 22, and the temperature of the ovarian area being lower than that of other areas. Heating zone 2 is divided into multiple independent temperature zones to meet the heat requirements of different parts of the abdomen; the controller 4 is used to control the heating of the heating film, using a Eurotherm 3504 controller, which can be connected to a temperature sensor 5.

[0019] In one embodiment, such as Figure 1 and Figure 3 As shown, the heating zone 2 has a groove 23 in the middle. The bottom of the groove 23 is larger than the lower half of the first heating film 21. The groove 23 avoids compressing the ovary after egg retrieval.

[0020] In one embodiment, such as Figure 4 As shown, the pad 1 includes a heat insulation layer 24, an aluminum foil heat-equalizing layer 25, a heating film layer 26, a silicone buffer layer 27, and a surface antibacterial layer 28, which are stacked and glued together in sequence. The surface antibacterial layer 28 is located at the bottom and contacts the skin, while the heat insulation layer 24 is located at the top and contacts the environment. The surface antibacterial layer 28 uses medical-grade silicone containing silver ions to achieve antibacterial effect through physical coverage. The silicone buffer layer 27 uses liquid silicone to adapt to the body contour through elastic deformation. The heating film layer 26 uses a polyimide (PI) based carbon fiber film, and the resistance distribution is controlled by etching circuits. The aluminum foil heat-equalizing layer 25 uses anodized aluminum foil to quickly conduct heat laterally and eliminate local hot spots in the heating film. The heat insulation layer 24 uses aerogel felt to isolate heat through low thermal conductivity.

[0021] In one embodiment, such as Figure 1 As shown, a temperature sensor 5 is provided between the first heating film 21 and the second heating film 22. The temperature sensor 5 is used to provide real-time temperature feedback to the controller 4.

[0022] In one embodiment, such as Figure 1 and Figure 2 As shown, the pad body 1 has a fixing strap 3 on its side. The free end of the fixing strap 3 is fixed with a hook and loop fastener 31, and the top surface of the pad body 1 is fixed with a hook and loop fastener 32 away from the fixing strap 3. The fixing strap 3 is used to fix the pad body 1.

[0023] In one embodiment, the thermal insulation layer 24 has a thickness of 1.5~2mm to balance thermal insulation with overall thickness; the aluminum foil heat-dissipating layer 25 has a thickness of 0.05~0.1mm, which has high thermal conductivity and does not affect flexibility; the heating film layer 26 has a thickness of 0.2~0.3mm, which is thin enough to bend and thick enough to provide uniform heating; the silicone buffer layer 27 has a thickness of 2~3mm to effectively buffer pressure and fill in body curves; and the surface antibacterial layer 28 has a thickness of 0.5~1mm to ensure antibacterial properties and not affect heat conduction.

[0024] Usage: Combine Figures 1-4 As shown, the spiral spacing and groove width of the etching groove 29 of the first heating film 21 are both greater than those of the etching groove 29 of the second heating film 22, so that the resistance of the first heating film 21 is greater than that of the second heating film 22, the temperature of the first heating film 21 is lower than that of the second heating film 22, and the temperature of the ovarian region is lower than that of other regions.

[0025] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
