Description

Technical Field

[0001] The present invention belongs to the technical field of examination support devices, and in particular relates to a support device for gynecological examination. Background Art

[0002] Gynecological examinations are an important part of women's health management. However, existing examination equipment has many problems. For example, the support structure of traditional examination chairs is fixed and cannot adapt to different body shapes, causing discomfort to patients. During the examination, patients are in a state of high physical and mental tension, so higher requirements are placed on the comfort of the chair. A comfortable chair can significantly help patients relax.

[0003] Most current seats use an integrated backrest design, but in fact, different parts of the human body require different support. Since the buttocks bear most of the body's weight, they must have sufficient support. The back should be softer to improve the shock absorption performance during pitching and rolling movements. The support for the waist is between the two. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a support device for gynecological examinations that can provide support in different areas; the present invention divides the backboard into three different areas, and respectively provides independent hip support airbags, waist support airbags and back support airbags. Since the hip support airbags, waist support airbags and back support airbags have independent air pressure requirements, they need to be individually controlled for intake and exhaust under normal circumstances; the present invention takes a different approach and creatively proposes an adaptive body pressure distribution support mechanism, which, through diversion and combined with springs of different elastic moduli, can automatically close the valve assembly after the air pressure increases to a threshold, thereby achieving the technical effect of automatically controlling the switch of the valve assembly during continuous air intake.

[0005] The technical solution adopted by the present invention is as follows: The present invention proposes a support device for gynecological examination, including an adaptive body pressure distribution support mechanism, an airbag support mechanism, and a leg support mechanism. The airbag support mechanism includes a backboard and an airbag assembly. The airbag assembly is arranged on the backboard and contains multiple sub-airbags with different pressures. Furthermore, the adaptive body pressure distribution support mechanism includes a diversion component, a valve component and a pressure sensing component. The diversion component is arranged on the back plate, and the valve component and the pressure sensing component are arranged in the diversion component.

[0006] The airbag assembly adopts a honeycomb air cushion array and air pressure self-balancing technology, which can provide personalized support with different pressure distributions on the hips, waist and back. It can ensure that the hip support airbag has strong support, and that the back support airbag and lumbar support airbag have good shock absorption performance.

[0007] Preferably, the diversion assembly includes a diversion valve and a diversion pipe. The diversion valve is fixed to the back plate. One side of the diversion valve is provided with a main channel connected to an external air source. The other side of the diversion valve is provided with three diversion ports in an array. The diversion pipe is also provided with three groups, and the diversion pipe is provided on the diversion port.

[0008] As a further preferred embodiment of the present invention, the valve assembly includes a valve seat and a valve cover, the valve seat is fixed to the inside of the diversion pipe, the valve cover is slidably arranged inside the diversion pipe, the valve seat is annularly evenly provided with circular holes, and the valve cover is annularly evenly provided with notches.

[0009] Through the structural design of the valve assembly and the pressure sensing assembly, the valve can be automatically closed when the pressure reaches a certain threshold, thereby limiting the maximum pressure inside the airbag.

[0010] The two ends of the valve cover are subjected to different air pressures, so the pressure difference on the valve cover can be balanced by the elastic force of the spring. As the air pressure changes, the compression amplitude of the spring will also change accordingly.

[0011] Preferably, the circular hole 1 and the notch do not overlap in the axial projection direction of the diverter tube.

[0012] As a further preferred embodiment of the present invention, the pressure sensing component includes a guide seat, which is fixed to the inside of the diverter pipe. A sliding rod is provided on the valve cover, and the sliding rod is engaged and slidably arranged in the guide seat. Two circular holes are evenly distributed in an annular shape on the guide seat, a flange is provided on the sliding rod, and a spring is provided between the flange and the guide seat.

[0013] Furthermore, the airbag assembly includes a buttocks support airbag, a waist support airbag and a back support airbag, and the buttocks support airbag, the waist support airbag and the back support airbag are arranged on the backboard in sequence.

[0014] Preferably, the three shunt tubes are respectively connected to the hip support airbag, the lumbar support airbag and the back support airbag, and the elastic moduli of the three springs are different, among which the elastic modulus of the spring in the shunt tube connected to the hip support airbag is the largest, and the elastic modulus of the spring in the shunt tube connected to the back support airbag is the smallest.

[0015] The springs connecting the three airbags adopt different elastic moduli, which can independently limit the maximum air pressure in the three airbags, thereby achieving the technical effect of different pressures in the three airbags under the diversion of the same air inlet.

[0016] Furthermore, the leg support mechanism includes a base and a leg support frame, the base is arranged below the backboard, and the leg support frame is arranged on the base.

[0017] Preferably, the leg support frame can be adjusted in angle and height.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The airbag assembly adopts a honeycomb air cushion array and air pressure self-balancing technology, which can provide personalized support with different pressure distributions on the buttocks, waist and back, ensuring that the buttocks support airbag has strong support and that the back support airbag and waist support airbag have good shock absorption performance.

[0019] (2) Through the structural design of the valve assembly and the pressure sensing assembly, the valve can be automatically closed when the pressure reaches a certain threshold, thereby limiting the maximum pressure inside the airbag.

[0020] (3) The air pressures at both ends of the valve cover are different, so the pressure difference on the valve cover can be balanced with the elastic force of the spring. As the air pressure changes, the compression amplitude of the spring will also change accordingly.

[0021] (4) The springs connecting the three airbags have different elastic moduli, which can independently limit the maximum air pressure in the three airbags, thereby achieving the technical effect of different pressures in the three airbags under the diversion of the same air inlet.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0027] like Figures 1 to 8 As shown, the present invention proposes a support device for gynecological examination, including an adaptive body pressure distribution support mechanism 1, an airbag support mechanism 2 and a leg support mechanism 3. The airbag support mechanism 2 includes a backboard 20 and an airbag assembly 21. The airbag assembly 21 is provided on the backboard 20 and contains multiple sub-airbags with different pressures. The adaptive body pressure distribution support mechanism 1 includes a diverter assembly 4 , a valve assembly 5 and a pressure sensing assembly 6 . The diverter assembly 4 is arranged on the back plate 20 , and the valve assembly 5 and the pressure sensing assembly 6 are arranged in the diverter assembly 4 .

[0028] The airbag assembly 21 adopts a honeycomb air cushion array and air pressure self-balancing technology, which can provide personalized support with different pressure distributions on the buttocks, waist and back, ensuring that the buttocks support airbag 22 has strong support, and ensuring that the back support airbag 24 and the waist support airbag 23 have good shock absorption performance.

[0029] The shunt assembly 4 comprises a shunt valve 7 and a shunt pipe 8, the shunt valve 7 is fixedly connected to the back plate 20, one side of the shunt valve 7 is provided with a main flow channel 14 connected to an external air source, and the other side of the shunt valve 7 is provided with three shunt openings 15 in an array, and the shunt pipe 8 is also provided with three groups, and the shunt pipe 8 is arranged on the shunt opening 15.

[0030] The valve assembly 5 comprises a valve seat 9 and a valve cover 10, the valve seat 9 is fixedly connected to the inside of the shunt pipe 8, and the valve cover 10 is slidingly arranged in the inside of the shunt pipe 8, and a plurality of circular holes one 16 are uniformly arranged in an annular shape on the valve seat 9, and a plurality of notches 17 are uniformly arranged in an annular shape on the valve cover 10.

[0031] Through the structural design of the valve assembly 5 and the pressure sensing assembly 6, the valve can be automatically closed when the pressure reaches a certain threshold, thereby realizing the function of limiting the maximum pressure inside the air bag.

[0032] The air pressure acting on the two ends of the valve cover 10 is different, so the pressure difference acting on the valve cover 10 can balance the elastic force of the spring 13, and with the change of the air pressure, the compression amplitude of the spring 13 will also change accordingly.

[0033] The circular hole one 16 and the notch 17 do not coincide in the axial projection direction of the shunt pipe 8.

[0034] The pressure sensing assembly 6 comprises a guide seat 11 fixedly connected to the inside of the shunt pipe 8, the valve cover 10 is provided with a sliding rod 18, the sliding rod 18 is slidingly clamped in the guide seat 11, a plurality of circular holes two 19 are uniformly arranged in an annular shape on the guide seat 11, a flange 12 is arranged on the sliding rod 18, and the spring 13 is arranged between the flange 12 and the guide seat 11.

[0035] The air bag assembly 21 comprises a hip support air bag 22, a waist support air bag 23 and a back support air bag 24, which are arranged in sequence on the back plate 20.

[0036] The three shunt pipes 8 are respectively connected to the hip support air bag 22, the waist support air bag 23 and the back support air bag 24, and the elastic moduli of the three springs 13 are different, among which the spring 13 in the shunt pipe 8 connected to the hip support air bag 22 has the largest elastic modulus, and the spring 13 in the shunt pipe 8 connected to the back support air bag 24 has the smallest elastic modulus.

[0037] The springs 13 connected to the three air bags have different elastic moduli, which can independently limit the maximum air pressure in the three air bags, thereby achieving the technical effect of different pressures in the three air bags under the shunt of the same air inlet.

[0038] The leg support mechanism 3 comprises a base 25 arranged below the back plate 20 and a leg support frame 26 arranged on the base 25.

[0039] The leg support frame 26 is capable of angle and height adjustment.

[0040] In use, first, the user needs to supply air to the main flow channel 14 through an external air source, and the air flow in the main flow channel 14 enters the three branch flow pipes 8 at the same pressure and enters the hip support air bag 22, the waist support air bag 23 and the back support air bag 24 respectively; As the pressure of the hip support air bag 22, the waist support air bag 23 and the back support air bag 24 continues to increase, the internal air pressure of the branch flow valve 7 and the branch flow pipe 8 also continues to increase, and the two ends of the valve cover 10 are subjected to different air pressure areas, so that the valve cover 10 has a pressure difference, which can be balanced with the elastic force of the spring 13; therefore, as the air pressure changes, the compression amplitude of the spring 13 also changes accordingly; The greater the internal air pressure of the branch flow valve 7 and the branch flow pipe 8, the greater the compression amplitude of the spring 13, so when the air pressure increases to a certain extent, the valve seat 9 and the valve cover 10 will be in close contact; Because the circular hole one 16 and the notch 17 do not coincide in the axial projection direction of the branch flow pipe 8, the branch flow pipe 8 changes from an open state to a closed state after the valve seat 9 and the valve cover 10 are in close contact, and thereafter even if the air pressure continues to increase, the branch flow pipe 8 will not open until the air pressure in the branch flow valve 7 decreases to below the threshold value.

[0041] Because the elastic modulus of the spring 13 in the three branch flow pipes 8 is different, the elastic modulus of the spring 13 in the branch flow pipe 8 connected to the hip support air bag 22 is the largest, and the elastic modulus of the spring 13 in the branch flow pipe 8 connected to the back support air bag 24 is the smallest, so during the process of continuously increasing the internal air pressure of the branch flow valve 7, the back support air bag 24 will first reach the set air pressure and close the corresponding valve assembly 5, then the waist support air bag 23 reaches the set air pressure and closes the corresponding valve assembly 5, and finally the hip support air bag 22 reaches the set air pressure and closes the corresponding valve assembly 5.

[0042] Finally, only the internal air pressure of the branch flow valve 7 needs to be maintained at a high value, and even if the air pressure in the air bag assembly 21 fluctuates due to the weight and movement impact of the human body during subsequent use, it is not enough to push away the valve cover 10 and the valve seat 9.

[0043] After the patient lies on the air bag support mechanism 2, the legs are placed on the leg support frame 26, and the leg support frame 26 is adjusted to the appropriate position.
