DETAILED DESCRIPTION

[0027] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0028] like Figure 1-2 As shown, the prenatal hip stretching exercise device proposed by the present invention includes a stretching exercise device 1, a seat 2, a lifting base 3, a backrest 5, a back ventilation device 6, armrests 7, and a real-time monitoring device 8. The stretching exercise device 1 is connected to the seat 2 and is located in the middle of the front end of the seat 2. The lifting base 3 is disposed at the bottom of the seat 2, the backrest 5 is mounted on the back of the seat 2, the back ventilation device 6 is disposed on the surface of the backrest 5, the armrests 7 are symmetrically disposed on both sides of the seat 2, and the real-time monitoring device 8 is disposed on the armrests 7. A support adjustment device 4 is disposed on the upper surface of the seat 2.

[0029] The stretching exercise device 1 includes a first telescopic portion, a second telescopic portion, and a third telescopic portion. The extension lengths of the first telescopic portion, the second telescopic portion, and the third telescopic portion increase in sequence, and the first telescopic portion, the second telescopic portion, and the third telescopic portion can operate independently. The exercise intensity of the stretching exercise device is divided into three levels: 1) In the first state, only the first telescopic portion is in operation, and the first telescopic portion periodically extends and contracts; 2) In the second state, the first and second telescopic portions are in operation. When the legs are apart, the first telescopic portion extends first, and then the second telescopic portion extends. When the legs are closed, the second telescopic portion contracts first, and then the first telescopic portion contracts; 2) In the third state, the first, second, and third telescopic portions are all in operation. When the legs are apart, the first, second, and third telescopic portions extend in sequence. When the legs are closed, the third telescopic portion, the second telescopic portion, and the first telescopic portion contract in sequence. During exercise, the pregnant woman's legs are located on both sides of the stretching exercise device, and each telescopic part acts on the thigh, stretching and contracting in stages, making the exercise process more soothing and gentle, and more suitable for pregnant women. Figure 3As shown, the first telescopic part includes two parts symmetrically arranged on both sides of the stretching exercise device. The two parts have the same structure and both include a first telescopic airbag 111, a first air chamber 113, a first inflation pump 114 and a first exhaust pump 115. A first pressure sensor 112 is provided on the surface of the first telescopic airbag 111. The first inflation pump 114 and the first exhaust pump 115 are arranged between the first telescopic airbag 111 and the first air chamber 113, and are used to realize the inflation and exhaust of the first telescopic airbag. When the first telescopic airbag is inflated, the first telescopic airbag continues to expand and gradually pushes the legs apart. When the data of the first pressure sensor is greater than the set threshold, it indicates that the first telescopic airbag is in close contact with the legs and it is necessary to stop inflating. When the first telescopic airbag is exhausted, the first telescopic airbag continues to shrink and the legs gradually close. The second telescopic part includes two parts symmetrically arranged on both sides of the stretching exercise device. The two parts have the same structure and both include a second telescopic airbag 121, a second air chamber 123, a second air pump 124 and a second air pump 125. A second pressure sensor 122 is provided on the surface of the second telescopic airbag 121. The second air pump 124 and the second air pump 125 are arranged between the second telescopic airbag 121 and the second air chamber 123 to realize the inflation and deflating of the second telescopic airbag. The working mode of the second telescopic airbag is the same as that of the first telescopic airbag. The third telescopic section comprises two symmetrically arranged sections on either side of the stretching exercise device. Both sections have identical structures, including a third telescopic airbag 131, a third air chamber 133, a third inflation pump 134, and a third deflator 135. A third pressure sensor 132 is provided on the surface of the third telescopic airbag 131. The third inflation pump 134 and the third deflator 135 are positioned between the third telescopic airbag 131 and the third air chamber 133, respectively, to inflate and deflat the third telescopic airbag. The third telescopic airbag operates in the same manner as the first telescopic airbag. The lengths of the first, second, and third telescopic airbags increase sequentially when fully extended, thereby increasing the extended lengths of the first, second, and third telescopic sections.

[0030] The lifting base 3 includes a cylinder, an air supply chamber is provided at the bottom of the cylinder, an air intake bag is provided on the air supply chamber, a one-way air intake valve is provided on the air intake bag, and an exhaust valve is also provided on the air supply chamber. The air intake bag on the air supply chamber is squeezed to make the air supply chamber push the cylinder to move, thereby raising the seat, and through the intermittent squeezing of the air intake bag, the seat can be slowly raised and the height can be adjusted. When the seat needs to be lowered, the exhaust valve is opened to lower the seat.

[0031] like Figure 2 As shown, the support adjustment device 4 includes a plurality of support adjustment units 41 arranged in an array. The support adjustment unit can adjust the support strength according to the contact pressure with the pregnant woman. By adjusting the contact pressure of each support adjustment unit, each support adjustment unit can achieve the same contact pressure, thereby achieving a more uniform support effect. Figure 4 As shown, the support adjustment unit 41 includes a support airbag 411, a support air chamber 413, a support inflation pump 414 and a support exhaust pump 415. A contact pressure sensor 412 is provided on the surface of the support airbag 411. The support inflation pump 414 and the support exhaust pump 415 are provided between the support airbag 411 and the support air chamber 413 to realize the inflation and exhaust of the support airbag. When the contact pressure is too large, the support airbag is exhausted. When the contact pressure is too small, the support airbag is inflated.

[0032] like Figure 5-6 As shown, the back ventilation device 6 is in a "U" shape and can wrap the back of a pregnant woman. The back ventilation device 6 includes an air heating unit 61, a support unit 62 and a temperature sensor 63. The air heating units are symmetrically distributed at the bottom of the side of the device, the temperature sensor is set at the center of the device, and the support units are evenly distributed along the top edge of the device. Figure 7 As shown, the support unit 62 includes a top plate 621, a movable rod 622, a base 623, a spring 624, a first connecting block 625, a micro-fan 626, and a second connecting block 627. The top plate 621 contacts the pregnant woman's back. The top plate 621, movable rod 622, and base 623 are sequentially connected. The elasticity of the spring ensures a certain gap between the pregnant woman's back and the back ventilation device. The first connecting block connects the micro-fan and the spring together, and the second connecting block connects the micro-fan to the surface of the back ventilation device. During operation, the air heating unit heats the air on the back and determines whether the air temperature reaches a specific threshold based on data from the temperature sensor. When the air temperature reaches the specific threshold, the micro-fan in the support unit is activated, causing air to flow upward. This reduces sweating on the back while ensuring that the pregnant woman does not catch a cold, thereby improving exercise comfort.

[0033] Real-time monitoring device 8 includes a millimeter-wave radar and a processor. The millimeter-wave radar emits signals that can penetrate clothing and measure tiny disturbances on the arm's skin surface. The processor receives the radar signals and calculates the pregnant woman's heart rate through processing. When the pregnant woman's heart rate exceeds a warning threshold (e.g., 125), the stretching device is controlled to stop functioning and an alarm is issued to medical staff. The millimeter-wave radar uses Infineon's XENSIV radar chip, a 60GHz frequency-modulated continuous wave radar ideally suited for measuring tiny disturbances on the skin surface caused by arterial pulses.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1) Multiple telescopic parts are used to achieve leg stretching exercises, which can not only adjust the training intensity, but also stretch and contract in stages, making the exercise process more soothing and gentle;

[0036] 2) The back ventilation device ensures air flow on the pregnant woman's back, reducing sweat on the back while ensuring that the pregnant woman does not catch a cold, thereby improving the comfort of exercise;

[0037] 3) The heart rate of pregnant women can be obtained in a non-contact manner through a real-time monitoring device to ensure the safety of exercise.

[0038] The above disclosure is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. It should be noted that for those skilled in the art, any equivalent changes made to the present invention without departing from the design structure and principles of the present invention are considered to be within the scope of protection of the present invention.
