Description

Technical Field

[0001] This invention relates to the field of hot compress devices, specifically to a hot compress device for dysmenorrhea. Background Technology

[0002] Dysmenorrhea is one of the most common gynecological symptoms, mainly manifested as lower abdominal pain or other discomfort. Applying heat to the lower abdomen can dilate blood vessels, improve local blood circulation, and promote local metabolism, making it one of the effective ways to relieve dysmenorrhea.

[0003] Most existing methods of applying heat to relieve menstrual cramps use hot water bottles. However, the temperature of the hot water bottle decreases over time, affecting its effectiveness. In addition, hot water bottles can only provide simple heat therapy and have limited effect on relieving menstrual cramps. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a hot compress device for dysmenorrhea, so as to solve the technical problem that when using hot water bottles to relieve dysmenorrhea symptoms in the prior art, hot water bottles can only provide simple heat application and have limited effect on relieving dysmenorrhea symptoms.

[0005] This invention is achieved through the following technical solution:

[0006] A menstrual cramp hot compress device, characterized in that: it includes a housing, the housing having a receiving cavity with the opening of the receiving cavity facing outward, and a water bladder fixed at the opening of the receiving cavity; the side of the housing is provided with a liquid injection component, the liquid injection component being used to inject a solution with temperature into the water bladder to expand the water bladder to apply a hot compress to the user's lower abdomen.

[0007] The liquid injection assembly includes a liquid storage tank containing a solution. The liquid storage tank is equipped with a temperature control mechanism for heating and maintaining the temperature of the solution. The liquid storage tank is connected to the water bladder via a first liquid guiding mechanism.

[0008] An electric telescopic rod is fixedly connected to the top of the liquid storage tank. The output end of the electric telescopic rod extends into the interior of the liquid storage tank, and a piston is fixedly connected to the output end of the electric telescopic rod. The electric telescopic rod pushes and pulls the piston up and down repeatedly, which can inject a solution into the water bag and then draw out the injected solution, thereby repeatedly driving the water bag to expand and protrude from the containing cavity to squeeze the user's lower abdomen.

[0009] Furthermore, the first liquid guiding mechanism includes a first liquid guiding pipe for connecting the liquid storage tank and the water bag, and a first solenoid valve is installed on the first liquid guiding pipe.

[0010] Furthermore, a partition is fixedly connected to the liquid storage tank, and a solution extrusion channel is formed between the partition and the liquid storage tank. The area of ​​the channel is adapted to the area of ​​the piston.

[0011] Furthermore, a pressing plate is rotatably connected to the receiving cavity. The pressing plate is located behind the water bladder, and the pressing plate is provided with a pushing component for pushing the turntable to deflect and squeeze the water bladder to perform massage.

[0012] Furthermore, the pushing assembly includes a sleeve fixedly connected to the inner wall of the housing, a movable rod inserted in the sleeve, one end of the movable rod extending out of the sleeve and rotatably connected to the pressing plate, and a second liquid guiding mechanism provided on the sleeve. When the electric telescopic rod pushes the piston down, the second liquid guiding mechanism can inject solution into the sleeve to drive the movable rod to push the pressing plate to deflect and squeeze the water bag for massage.

[0013] Furthermore, the second liquid guiding mechanism includes a second liquid guiding tube for connecting the first liquid guiding tube and the sleeve, and a second solenoid valve is installed on the second liquid guiding tube.

[0014] Furthermore, a slider is fixedly connected to one end of the movable rod that extends into the sleeve, and a blocking element is provided between the sleeve and the movable rod.

[0015] Furthermore, a spring telescopic rod is fixedly connected to the side of the pressing plate near the water bladder, and a pressing head is rotatably connected to the end of the spring telescopic rod away from the pressing plate.

[0016] Furthermore, a number of pressing protrusions are fixedly connected to the outer circumferential surface of the pressing head.

[0017] Furthermore, the housing is provided with a plurality of positioning blocks, which are respectively located at the corners of the water bladder for positioning and installation of the water bladder and for restricting the expansion direction of the water bladder.

[0018] The beneficial effects of this invention are as follows:

[0019] This menstrual cramp relief hot compress device heats a supersaturated saline solution in a reservoir using a temperature control mechanism. After heating, the solution is kept warm. The user then wears the device, placing the housing on their lower abdomen. By controlling the electric telescopic rod to push the piston downwards, the solution in the reservoir is forced into the water bladder through a first liquid guiding mechanism. The water bladder then expands, protruding from the receiving cavity and contacting the user's lower abdomen for heat therapy, thereby relieving lower abdominal pain. The piston moves up and down repeatedly by the electric telescopic rod. After the solution is injected into the water bladder, it is then drawn out, causing the water bladder to expand intermittently. This intermittent expansion of the water bladder allows for repeated compression and massage of the user's lower abdomen. Furthermore, when a solution with a certain temperature is injected into the water bladder, the heat transfer effect causes the solution to heat the air between the water bladder, the shell, and the user's body. As the electric telescopic rod pushes and pulls the piston up and down, it simultaneously massages and applies heat to the user's lower abdomen, thus better relieving the discomfort caused by menstrual cramps.

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible. The term "perpendicular" simply means that the positional relationship between components is more perpendicular than "parallel," not that the structure must be perfectly perpendicular; a slight tilt is acceptable.

[0031] Please see Figures 1 to 4This invention provides a technical solution: a menstrual cramp hot compress device, comprising a housing 11, the housing 11 having a receiving cavity 2 with the opening of the receiving cavity 2 facing outwards, and a rubber frame being fitted onto the housing 11 near the opening of the receiving cavity 2 to improve the comfort of the user's body in contact with the hot compress device; a water bladder 3 is fixedly provided at the opening of the receiving cavity 2, the water bladder 3 being made of silicone and initially containing no gas; a liquid injection component 4 is provided on the side of the housing 11, the liquid injection component 4 being used to inject a solution with temperature into the water bladder 3 to expand the water bladder 3 to provide a hot compress to the user's lower abdomen;

[0032] The liquid injection component 4 includes a liquid storage tank 41. A waist belt is provided on the outside of the liquid storage tank 41 for the user to wear the hot compress device of the present invention. The liquid storage tank 41 stores a solution, which is a supersaturated salt solution commonly used in electric hot water bags. The liquid storage tank 41 is provided with a temperature control mechanism 42 for heating and keeping the solution warm. The temperature control mechanism 42 includes an electric heating rod, a storage battery, and a temperature controller (not shown). The storage battery provides energy for the operation of the electric heating rod, while the temperature controller is used to control the temperature of the solution so that the solution reaches the set temperature. The specific structure and working principle of the temperature control mechanism 42 are existing technologies and will not be described in detail here. The liquid storage tank 41 and the water bag 3 are connected through a first liquid guiding mechanism 43.

[0033] An electric telescopic rod 44 is fixedly connected to the top of the liquid storage tank 41. The output end of the electric telescopic rod 44 extends into the interior of the liquid storage tank 41, and a piston 45 is fixedly connected to the output end of the electric telescopic rod 44. The electric telescopic rod 44 pushes and pulls the piston 45 up and down, which can inject a solution into the water bag 3 and then draw out the injected solution, thereby repeatedly driving the water bag 3 to expand and protrude from the receiving cavity to squeeze the user's lower abdomen.

[0034] In use, the hot compress device for menstrual cramps of the present invention first heats the supersaturated salt solution in the storage tank 41 through the temperature control mechanism 42. After heating, it is kept warm. Then, the user wears the hot compress device and places the housing 11 on the lower abdomen. By controlling the electric telescopic rod 44 to push the piston 45 downward, the solution in the storage tank 41 is forced into the water bag 3 through the first liquid guiding mechanism 43. At this time, the water bag 3 expands and protrudes from the receiving cavity 2 to contact the user's lower abdomen for hot compress, thereby relieving the user's lower abdominal pain. The electric telescopic rod 44 pushes and pulls the piston 45 back and forth. The piston 45 moves up and down, injecting the solution into the water bladder 3 and then drawing the solution out of the water bladder 3, thereby intermittently driving the water bladder 3 to expand. By intermittently driving the water bladder 3 to expand, it can repeatedly squeeze and massage the user's lower abdomen. When a solution with a certain temperature is injected into the water bladder 3, due to the effect of heat transfer, the solution with a certain temperature will heat the air between the water bladder 3, the shell 11 and the user's body. Therefore, when the electric telescopic rod 44 pushes and pulls the piston 45 up and down, it can simultaneously perform massage and heat application on the user's lower abdomen to better relieve the discomfort caused by dysmenorrhea symptoms.

[0035] Please see Figure 3 In this embodiment, the first liquid guiding mechanism 43 includes a first liquid guiding pipe 431 for connecting the liquid storage tank 41 and the water bag 3, and a first solenoid valve 432 is installed on the first liquid guiding pipe 431.

[0036] In this design, the interior of the storage tank 41 is connected to the interior of the water bag 3 via the first liquid guide tube 431. The first solenoid valve 432 controls the opening and closing of the first liquid guide tube 431. When the electric telescopic rod 44 pushes the piston 45 downward to squeeze the solution, the first solenoid valve 432 controls the first liquid guide tube 431 to open, and the solution is introduced into the water bag 3 through the first liquid guide tube 431 to apply heat to the user's lower abdomen. Two sets of injection components 4 are respectively provided at both ends of the housing 11. When the user feels that the temperature in the water bag 3 has dropped, the electric telescopic rod 44 pulls the piston 45 upward to move it, and the solution in the water bag 3 is re-drawn into the storage tank 41 for heating. Then, the first solenoid valve 432 controls the first liquid guide tube 431 to close. Finally, the other set of injection components 4 works to re-inject hot water into the water bag 3. Thus, the alternating circulation of the two sets of injection components 4 can ensure the heat application effect.

[0037] Please see Figure 2In this embodiment, a partition 46 is fixedly connected in the liquid storage tank 41, and a solution squeezing channel is formed between the partition 46 and the liquid storage tank 41. The area of ​​the channel is adapted to the area of ​​the piston 45.

[0038] In this design, the area of ​​the solution squeezing channel formed between the partition 46 and the liquid storage tank 41 is adapted to the area of ​​the piston 45. Thus, when the electric telescopic rod 44 pushes the piston 45 to press down the solution, a vacuum appears above the piston 45, which facilitates the smooth injection of the solution into the water bladder 3 or the extraction of the solution from the water bladder 3.

[0039] Please see Figure 3 and Figure 4 In this embodiment, a pressing plate 5 is rotatably connected in the receiving cavity 2. The pressing plate 5 is located behind the water bag 3. A pushing component 6 is provided on the pressing plate 5 for pushing the pressing plate 5 to deflect and squeeze the water bag 3 to perform massage.

[0040] The pushing component 6 includes a sleeve 61 fixedly connected to the inner wall of the housing 11. A movable rod 62 is inserted into the sleeve 61. One end of the movable rod 62 extending out of the sleeve 61 is rotatably connected to the pressing plate 5. A second liquid guiding mechanism 63 is provided on the sleeve 61. When the electric telescopic rod 44 pushes the piston 45 down, the second liquid guiding mechanism 63 can inject solution into the sleeve 61 to drive the movable rod 62 to push the pressing plate 5 to deflect and squeeze the water bag 3 for massage.

[0041] The second liquid guiding mechanism 63 includes a second liquid guiding pipe 631 for connecting the first liquid guiding pipe 431 and the sleeve 61, and a second solenoid valve 632 is installed on the second liquid guiding pipe 631.

[0042] In this design, the volume of the solution stored in the storage tank 41 is greater than the volume of the water bladder 3. When a certain volume of solution is filled into the water bladder 3 without completely filling it, the water bladder 3 does not come into contact with the user's lower abdomen. However, due to heat transfer, the warm solution will heat the air between the water bladder 3, the shell 11, and the user's body, thus providing a heat compress to the user's lower abdomen. At this time, the first solenoid valve 432 controls the first liquid guide tube 431 to close, and the second solenoid valve 632 controls the second liquid guide tube 631 to open. When the electric telescopic rod 44 continues to push the piston 45 to press down the solution, the solution is introduced into the sleeve 61 through the second liquid guide tube 631, and pushes the movable rod 62 to extend out of the sleeve. When the sleeve 61 and the movable rod 62 extend, they push the pressing plate 5 to deflect, causing the pressing plate 5 to squeeze the water bag 3. The water bag 3 is squeezed and deformed, moving closer to the user's lower abdomen, giving the user a pressing sensation. At the same time, the water bag 3 is squeezed, and the solution inside flows to the other side of the water bag 3, causing the other side of the water bag 3 to protrude from the receiving cavity 2 to massage the user's lower abdomen. The electric telescopic rod 44 pushes the piston 45 up and down to squeeze and draw out the solution, driving the pressing plate 5 to deflect back and forth to massage the user's lower abdomen. Compared with the method of repeatedly drawing out the solution to drive the water bag 3 to repeatedly expand, this massage method requires less solution to flow, has a higher massage frequency per unit time, and can massage both sides of the lower abdomen, resulting in a better massage effect.

[0043] Please see Figure 4 In this embodiment, a slider 64 is fixedly connected to one end of the movable rod 62 that extends into the sleeve 61, and a blocking member 65 is provided between the sleeve 61 and the movable rod 62.

[0044] In this solution, the stroke of the slider 64 is limited by the blocking member 65, thereby preventing the movable rod 62 from being squeezed and slid apart from the sleeve 61 by the solution. The slider 64 is fitted with a sealing ring (not shown) to prevent leakage at the connection between the sleeve 61 and the movable rod 62.

[0045] Please see Figure 4 In this embodiment, a spring telescopic rod 66 is fixedly connected to the side of the pressing plate 5 near the water bag 3, and a pressing head 67 is rotatably connected to the end of the spring telescopic rod 66 away from the pressing plate 5.

[0046] In this design, when the pressing plate 5 deflects, it can drive the pressing head 67 to approach and squeeze the water bag 3. At this time, the spring telescopic rod 66 is compressed and shortened. The thrust generated by the deformation of the spring in the spring telescopic rod 66 pushes the pressing head 67 to press the user's lower abdomen. After the spring telescopic rod 66 is compressed, as the pressing plate 5 deflects, it drives the pressing head 67 to move along the length of the water bag 3, which can better push the solution in the water bag 3 to flow to the other side. This causes the other side of the water bag 3 to expand and protrude from the receiving cavity 2 to squeeze and massage the user's lower abdomen. At the same time, the lateral movement of the pressing head 67 can squeeze and move laterally to massage the user's lower abdomen, further improving the massage effect on the user's lower abdomen and better relieving the symptoms caused by menstrual cramps.

[0047] Please see Figure 4 In this embodiment, a plurality of pressing protrusions 68 are fixedly connected to the outer circumferential surface of the pressing head 67.

[0048] In this solution, when the deflection of the pressing plate 5 drives the pressing head 67 to move along the length of the water bag 3, the pressing head 67 rotates with the spring telescopic rod 66. When the pressing head 67 rotates, it can squeeze multiple points of the water bag 3 through the pressing protrusion 68, thereby squeezing and massaging multiple points of the user's lower abdomen, further improving the massage efficiency.

[0049] Please see Figure 3 In this embodiment, the housing 11 is provided with a plurality of positioning blocks 7, which are respectively located at the corners of the water bladder 3 for positioning and installation of the water bladder 3 and for restricting the expansion direction of the water bladder 3.

[0050] In this solution, the positioning block 7 is used for positioning and installing the water bag 3, so that the water bag 3 expands in both forward and backward directions when it expands. When it expands forward, it can extend out of the receiving cavity 2 to squeeze and massage the user's lower abdomen. When it expands backward, it can extend to the front of the pressing head 67, which is beneficial for the pressing head 67 to squeeze the water bag 3 for massage.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
