Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, to an auxiliary device for obstetrics and gynecology ultrasonic examination. Background Art

[0002] In the prior art, flat examination beds are mostly used for ultrasonic diagnosis of pregnant women. During use, the patient needs to lie on the examination bed and receive the examination in a supine position. When pregnant women in the late pregnancy lie down on the flat bed and get up, due to the limitation of their bulky body shape, they need the assistance of medical staff. Because pregnant women are heavier and female medical staff in hospitals have relatively poor physical strength, the experience of pregnant women during ultrasonic diagnosis is poor. At the same time, it also increases the workload of medical staff. In order to improve this problem in the prior art, the examination bed has been improved. However, the improved examination bed in the prior art can only be lifted up and down, thus assisting pregnant women to sit up. When lying down, first, the pregnant woman needs to sit on the edge of the bed from the side of the examination bed, then move her body to the middle of the bed, and then use the lifting device to lie down or get up. Although it provides certain assistance to the movement of pregnant women, it is still not convenient enough.

[0003] When performing a B-ultrasound examination on a pregnant woman, she often needs to lie on her side. However, the prior art cannot assist the pregnant woman to lie on her side. Especially for pregnant women in the late pregnancy, it is extremely inconvenient to lie on their side by themselves. In addition, after the pregnant woman adjusts her body position, some parts of her body will bear greater pressure, such as the waist, back, etc., increasing the fatigue and discomfort of the pregnant woman. The prior art has a limited range of adjustment for the body position angle of pregnant women, and may not be able to provide appropriate support and adjustment for obese, pregnant women with special body shapes or short stature.

[0004] Therefore, the present invention provides an auxiliary device for obstetrics and gynecology ultrasonic examination. Summary of the Invention

[0012] Preferably, the second flipping assembly includes a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod. The first connecting rod and the second connecting rod are respectively hinged to the bottom of the seat plate, and the third connecting rod and the fourth connecting rod are respectively hinged to the bottom of the leg plate. The free ends of the first connecting rod and the third connecting rod are hinged to each other. The free ends of the second connecting rod and the fourth connecting rod are hinged to each other, and the middle parts of the second connecting rod and the third connecting rod are hinged to each other. The first connecting rod and the fourth connecting rod, and the second connecting rod and the third connecting rod are arranged in central symmetry.

[0013] Preferably, the linkage assembly includes a motor installed on the top of the mounting seat. The output shaft of the motor is fixedly connected to the second connecting rod through a rotating shaft. A transmission rod is rotatably provided on the top of the mounting seat away from the motor.

In addition, the extension plate can be suitable for pregnant women of different heights and body types.

[0017] 2. When a pregnant woman lying on her back needs to turn over to the left, she bends her right leg. Since the contact area becomes smaller, the pressure will increase. In the second airbag group on the leg board, among the micro airbags on the right side of the pregnant woman, the pressure sensors on some of the micro airbags will sense a sudden increase in pressure, and then transmit the signal to the intelligent micro control board. The intelligent micro control board controls the air pump to inflate the corresponding micro airbags in the first airbag group, the second airbag group, and the third airbag group to assist the pregnant woman in turning over. Although during the turning-over process, the pressure sensors on the micro airbags on the left side of the pregnant woman will sense an increase in pressure, since the contact area between the left leg and the micro airbags has not changed, the pressure sensors will not sense a sudden increase in pressure, so it will not cause the air pump to inflate the micro airbags on the left side of the pregnant woman, thus achieving the purpose of assisting the pregnant woman in turning over. The provided lumbar support airbag and abdominal support airbag can relieve the pressure on the waist and abdomen of the pregnant woman, and further relieve the fatigue and discomfort of the pregnant woman.

DETAILED DESCRIPTION OF THE INVENTION

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments: Embodiment

[0021] As Figures 1 to 6 shown, an auxiliary device for obstetrics and gynecology ultrasound examination includes a support frame 1, which is composed of a U-shaped frame and four support legs distributed at the bottom of the U-shaped frame. A seat plate 2 is fixedly provided at the top of the opening of the U-shaped frame. One end of the seat plate 2 close to the opening of the U-shaped frame is hinged with a leg plate 4 through a first flipping assembly, and the other end of the base is hinged with a back plate 3 through a second flipping assembly. The back plate 3 includes a back region and a waist region, and a linkage assembly is provided between the first flipping assembly and the second flipping assembly.

[0022] An installation seat 11 is provided at the bottom of the U-shaped frame. The first flipping assembly includes first connecting rods 16 symmetrically hinged to both sides of the bottom of the back plate 3. The first connecting rods 16 are hinged with second connecting rods 17 that are rotationally clamped to the installation seat 11. The two second connecting rods 17 are fixedly connected through a rotating shaft. One end of the back plate 3 close to the seat plate 2 is rotationally clamped to the support frame 1.

[0023] Through the first flipping assembly, the patient can be assisted to lie down and get up. Under the limitation of the back plate 3, the second connecting rod 17 rotates, which can push the angle between the first connecting rod 16 and the second connecting rod 17 to change, thereby achieving the purpose of flipping the back plate 3.

[0024] The second flipping assembly includes a first connecting rod 18, a second connecting rod 19, a third connecting rod 20, and a fourth connecting rod 21. The first connecting rod 18 and the second connecting rod 19 are respectively hinged to the bottom of the seat plate 2, and the third connecting rod 20 and the fourth connecting rod 21 are respectively hinged to the bottom of the leg plate 4; the free ends of the first connecting rod 18 and the third connecting rod 20 are hinged; the free ends of the second connecting rod 19 and the fourth connecting rod 21 are hinged, and the middle parts of the second connecting rod 19 and the third connecting rod 20 are hinged; the first connecting rod 18 and the fourth connecting rod 21, and the second connecting rod 19 and the third connecting rod 20 are symmetrically arranged about the center. There are two groups of the second flipping assemblies, which are symmetrically distributed on both sides of the seat plate 2 and the leg plate 4.

[0025] The linkage assembly includes a motor 22 installed on the top of the installation seat 11. The output shaft of the motor 22 is fixedly connected to the second connecting rod 17 through a rotating shaft. A transmission rod 23 is rotatably provided on the top of the installation seat 11 away from the motor 22. A first belt 24 is sleeved on the rotating shafts between the transmission rod 23 and the two second connecting rods 17 through fixed transmission wheels. A second belt 25 is sleeved on the transmission rod 23 and the first connecting rod 18 close to the seat plate 2 through transmission wheels.

[0026] Through the settings of the first flipping component, the second flipping component and the linkage component, it is possible to realize that a motor 22 drives the backboard 3 and the leg board 4 to flip, so as to assist the pregnant woman to get up and lie down. In the initial state, the backboard 3 is perpendicular to the seat board 2 upwards, and the leg board 4 is downwards and parallel to the seat board 2. The pregnant woman sits on the seat board 2, and moves her buttocks as close to the backboard 3 as possible, and presses her back tightly against the backboard 3. Start the motor 22, and the output shaft of the motor 22 rotating counterclockwise can drive the second connecting rod to rotate counterclockwise. Since one end of the backboard 3 is rotatably connected to the support frame 1, the rotating second connecting rod 17 can drive the angle between the first connecting rod 16 and the second connecting rod 17 to decrease, so as to achieve the purpose of flipping the backboard 3 downwards counterclockwise. At the same time, the rotating shaft between the second connecting rods 17 rotating counterclockwise rotates counterclockwise with the second connecting rod 17, driving the first belt 24 and the second belt 25 to rotate counterclockwise in turn, and then driving the first connecting rod 18 to rotate counterclockwise; thus transmitting the force to the second flipping component. The rotating first connecting rod 18 pushes the third connecting rod 20 to move clockwise, and then drives the second connecting rod 19 to rotate counterclockwise and the fourth connecting rod 21 to rotate clockwise; so that the angles between the first connecting rod 18 and the third connecting rod 20 and between the second connecting rod 19 and the fourth connecting rod 21 continue to increase, so as to achieve the purpose of flipping the leg board 4 upwards until the upper surfaces of the backboard 3, the leg board 4 and the seat board 2 are on the same horizontal plane. At this time, the support frame 1 can support the backboard 3, and thus assist the pregnant woman to lie flat. Similarly, the output shaft of the motor 22 rotating clockwise can drive the backboard 3 to flip upwards and drive the leg board 4 to flip downwards at the same time, so as to assist the pregnant woman to sit up, avoiding the compression of the pregnant woman's abdomen caused by only assisting the upper body of the pregnant woman to get up and lie down in the prior art.

[0027] In this embodiment, when the pregnant woman gets up and lies down, due to the inability to borrow strength and relying entirely on the support of the backboard and the leg board, it is easy to cause a sense of weightlessness and easily cause the pregnant woman to be nervous and lead to uterine contractions; therefore, handle 28 assemblies are symmetrically arranged on both sides of the support frame 1. The handle 28 assembly includes five support rods 27 hinged to the top of the support frame 1, and a handle 28 is jointly hinged to the tops of the five support rods 27; a limiting plate 29 is sleeved on the support rod 27 close to the push plate, a limiting hole 30 is arranged at the top of the limiting plate 29, and a wedge block 33 is arranged at one end of the limiting plate 29 away from the support rod 27; the bottom of the handle 28 is slidably clamped with a limiting block 31 through a spring, a limiting rod 32 adapted to the limiting hole 30 is arranged at the bottom of the limiting block 31, and the bottom of the limiting rod 32 is a curved surface.

[0028] When assisting a pregnant woman to get up or lie down, lift the handle 28 upward, which can drive the support rod 27 to rotate counterclockwise. When the bottom of the limit rod 32 abuts against the wedge block 33, the spring between the limit block 31 and the handle 28 is compressed. Until the support rod 27 is in a vertical state with the support frame 1, the limit rod 32 is directly above the limit hole 30; the restoring force of the compressed spring drives the limit rod 32 to insert into the limit hole 30, playing a role in locking the handle 28. The pregnant woman can hold the handle 28 for leverage to relieve the sense of weightlessness when getting up or lying down. When medical staff perform a B-ultrasound examination on the pregnant woman, they can hold the limit block 31 and the handle 28. The limit block 31 moves upward, squeezing the spring, and the limit rod 32 disengages from the limit hole 30 to release the limit on the handle 28. Applying force to make the support rod 27 rotate clockwise can lower the handle 28 to avoid interfering with the medical staff.

[0029] When performing a B-ultrasound examination on a pregnant woman, the pregnant woman often needs to lie on her side. It is extremely inconvenient for the pregnant woman to turn from lying flat to lying on her side by herself. On the basis of the above technical solution, the top parts of the seat board 2, the leg board 4, and the back board 3 are respectively provided with a first airbag group 5, a second airbag group 6, and a third airbag group 7. The first airbag group 5, the second airbag group 6, and the third airbag group 7 are provided with nine groups of micro airbags along the width direction of the support frame 1. Each group of micro airbags is composed of several micro airbags 8 that are connected and distributed in a linear array. Each group of micro airbags is respectively connected to an air pump 9 and an air extraction pump through an air charging pipe and an air discharging pipe. The air pump 9 and the air extraction pump 10 are arranged on the top of the mounting seat 11; solenoid valves are installed on the air charging pipe and the air discharging pipe. Pressure sensors 12 are installed on the surfaces of the micro airbags 8 in each group of micro airbags; a smart micro control board 13 electrically connected to the pressure sensors 12, the air pump 9, and the air extraction pump is arranged on the side of the support frame 1.

[0030] When a pregnant woman lying flat needs to turn over to the left, first bend the right leg. Since the contact area becomes smaller, the pressure will increase. Among the second airbag group 6 on the leg board 4, the pressure sensors 12 on individual micro airbags 8 on the same group of micro airbags on the right side of the pregnant woman will sense a sudden increase in pressure, and then transmit the signal to the smart micro control board 13. The smart micro control board 13 controls the air pump 9 to inflate all the micro airbags 8 in the corresponding same group of micro airbags in the first airbag group 5, the second airbag group 6, and the third airbag group 7 to assist the pregnant woman to turn over. During the turning-over process, the handle 28 on the left side can also be pulled up for leverage to prevent excessive weightlessness during the turning-over. Although during the turning-over process, the pressure sensors 12 on the micro airbags 8 in the micro airbags on the left side of the pregnant woman will sense an increase in pressure, since the contact area between the left leg and the micro airbag 8 has not changed, the pressure sensors 12 will not sense a sudden increase in pressure, so it will not cause the air pump 9 to inflate the micro airbags on the left side of the pregnant woman, thus achieving the purpose of assisting the pregnant woman to turn over.

[0031] In the late pregnancy, a pregnant woman's abdomen and waist need to bear a relatively large force. To improve the comfort of B-ultrasound examination for pregnant women, the backboard 3 is provided with a back area and a waist area, and the third airbag group 7 is distributed in the back area of the backboard 3; the first airbag group 5 is distributed on the top of the seat board 2 and the waist area of the backboard 3; the first airbag group 5 located in the waist area of the backboard 3 is provided with a fourth airbag group, and the fourth airbag group is provided with lumbar support airbags 14 corresponding to each of the nine micro airbags in the first airbag group 5 along the width direction of the support frame 1. Each micro airbag and the corresponding lumbar support airbag 14 are respectively connected to an air inflation pipe and an air deflation pipe through a three-way pipe, and are connected to an air inflation pump 9 and an air extraction pump 10; a solenoid valve is installed on the three-way pipe. The intelligent micro control board 13 controls the air inflation pump 9 to inflate the lumbar support airbags 14 corresponding to the waist of the pregnant woman. After inflation, the lumbar support airbags 14 abut against the waist of the pregnant woman, which can relieve the pressure borne by the waist of the pregnant woman, and thus relieve the fatigue and discomfort of the pregnant woman.

[0032] As a preferred solution of this embodiment, the thickness of the airbag walls at both ends of the lumbar support airbag 14 is thicker than that of the middle area. Thus, when inflated, the lumbar support airbag 14 can better fit the body curve of the human waist.

[0033] When a pregnant woman in the late pregnancy lies on her side, her abdomen also bears a relatively large pressure. A fifth airbag group is provided on the top of the fourth airbag, and the fifth airbag group is provided with abdominal support airbags 15 corresponding to each of the nine micro airbags in the first airbag group 5 along the width direction of the support frame 1; the abdominal support airbags 15 are connected to the air inflation pump 9 and the air extraction pump 10 through an air inflation pipe and an air deflation pipe. The thickness of the airbag walls at both ends of the abdominal support airbag 15 is thinner than that of the middle area. Thus, when inflated, the abdominal support airbag 15 can better fit the abdominal curve of the human body, and thus relieve the pressure borne by the abdomen of the pregnant woman, and relieve the fatigue and discomfort of the pregnant woman.

[0034] An elastic airbag is provided between two micro airbags 8 located at the connection between the backboard 3 and the seat board 2 and at the connection between the leg board 4 and the seat board 2. In order to be applicable to pregnant women of different heights, one end of the leg board 4 away from the seat board 2 is hinged with an extension board 26 through a damper. When the extension board 26 is in the same horizontal plane as the seat board, the extension board 26 abuts against the leg board 4, so as to ensure that the extension board 26 will not turn down. When performing B-ultrasound examination, medical staff often need to bend down, and the lumbar spine of medical staff is prone to be damaged after bending down for a long time. In order to be applicable to medical staff of different heights, hydraulic cylinders can also be installed at the bottoms of the four support legs of the support frame 1; in order to further improve the comfort of pregnant women; breathable pads are provided on the tops of the first airbag group 5, the second airbag group 6 and the third airbag group 7.

[0035] In addition, the intelligent micro control board can also manually adjust the inflation and deflation of the micro airbags 8, the lumbar support airbags 14 and the abdominal support airbags 15 in each group of micro airbags.

[0036] The working principle is as follows: In the initial state, the backboard 3 is perpendicular to the seat board 2 upwards, the leg board 4 is downwards and perpendicular to the seat board 2. The pregnant woman sits on the seat board 2 and moves her buttocks as close as possible to the backboard 3, pressing her back tightly against the backboard 3. The pregnant woman holds the armrests for leverage and starts the motor 22. The output shaft of the motor 22 rotating counterclockwise can drive the backboard 3 to flip down counterclockwise. At the same time, power is transmitted through the linkage assembly to drive the leg board 4 to flip upwards until the upper surfaces of the backboard 3, the leg board 4 and the seat board 2 are on the same horizontal plane, thereby assisting the pregnant woman to lie flat. When the lying pregnant woman needs to be examined in a side-lying position, such as when turning over to the left, first bend the right leg. Since the contact area becomes smaller, the pressure will increase. Among the second airbag group 6 on the leg board 4, the pressure sensors 12 on individual micro airbags 8 of the same group on the right side of the pregnant woman will sense a sudden increase in pressure, and then transmit the signal to the intelligent micro control board 13. The intelligent micro control board 13 controls the air pump 9 to inflate the corresponding micro airbags in the first airbag group 5, the second airbag group 6 and the third airbag group 7 to assist the pregnant woman to turn over. The lumbar airbag 14 and the abdominal airbag 15 can relieve the pressure on the waist and abdomen of the pregnant woman, thereby alleviating the fatigue and discomfort of the pregnant woman.

[0037] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application shall be subject to the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
