Description

Technical Field

[0001] The present invention relates to the technical field of gynecological delivery instruments, and particularly relates to a delivery ball fixing device for free-position delivery. Background Art

[0002] Delivery, commonly known as giving birth, specifically refers to the period and process in which a fetus detaches from the mother's body and becomes an independent individual. The whole process of delivery is divided into 3 stages, also known as 3 labor stages. The first stage is the cervical dilation stage. The second stage is the fetal expulsion stage. The third stage is the placental expulsion stage. In order to ensure the smooth delivery of the fetus, some obstetrics and gynecology instruments are used for auxiliary training before the fetus is born, so as to assist in dilation and relieve the anxiety of pregnant women.

[0003] An existing delivery ball used in obstetrics and gynecology generally adopts a sitting or standing position during use. When a pregnant woman uses this surgical instrument, due to the smooth surface and strong elasticity of the delivery ball, the pregnant woman is prone to problems such as unstable center of gravity or side slip when moving on it. And because most delivery balls do not have a limiting device during use, they are also prone to side slip when being squeezed, further increasing the risk of the pregnant woman falling. Therefore, during the training of pregnant women, medical staff or family members need to watch at all times and use their bodies to help the pregnant woman maintain stability. And when family members and medical staff assist the pregnant woman in exercising, they can also gently massage the pregnant woman's waist and back to further relieve the anxiety of the pregnant woman, make her body and mind more comfortable, and then increase the effect of exercise. However, the above operations not only consume a lot of manpower, but also are more troublesome to operate. Therefore, the present application provides a delivery ball fixing device for free-position delivery to meet the needs. Summary of the Invention

[0004] The present invention provides a delivery ball fixing device for free-position delivery. By setting an auxiliary limiting mechanism and a back support limiting mechanism, it can not only be flexibly adjusted according to the specific on-site use situation, so that the adjusted device can be applicable to the auxiliary movements of the sitting and standing postures of pregnant women, but also the structure effectively enhances the stability of the device.

[0013] Optionally, a reinforcing frame is fixedly connected to the top of the second limiting plate. A plurality of fourth lightening grooves are equidistantly arranged on the reinforcing frame, and the cross section of the reinforcing frame is corrugated.

[0014] Optionally, the back support limiting mechanism includes a back plate installed on the connecting plate. A bump is provided on the outer wall of the side of the back plate away from the connecting plate, and second guiding parts are fixedly connected to both sides of the back plate.

[0015] Optionally, the back plate is a circular arc structure adapted to the shape of the human back. A buffer cavity is formed in the second guiding part. Fifth lightening grooves are equidistantly formed in the back plate, and connecting blocks are fixedly connected to both sides of the bottom of the back plate.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by providing the auxiliary limiting mechanism and the back support limiting mechanism, it can not only be flexibly adjusted according to the specific use situation on site, so that the adjusted device can be applicable to the auxiliary movements of the sitting and standing postures of pregnant women, but also the structure effectively enhances the stability during the use of the birthing ball, effectively confines the birthing ball to move within a specific movement space, so that it will not skid, and while limiting the birthing ball, it also has an auxiliary limiting and supporting effect on the posture of the pregnant woman, effectively preventing the problem that the pregnant woman may fall due to unstable center of gravity during the movement. And by using the elastic cooperation between the structures, when the birthing ball between the two first limiting plates is squeezed and deformed, the structures will generate corresponding deformation activities along with the deformation of the birthing ball, so that the parts in the auxiliary limiting mechanism and the back support limiting mechanism that are in contact with the skin of the pregnant woman not only play a role in supporting and limiting the pregnant woman, but also massage the contact parts, thereby increasing the comfort of the pregnant woman. The combined use of the structures not only makes the device more practical, but also has a simple structure and is convenient and fast to use.

[0018] By providing a first limiting plate in the auxiliary limiting mechanism, connecting the first limiting plate and the main body of the mounting plate together by using a support rod, and through the combined use of the second mounting groove, the first lightening groove and the first mounting screw, the first limiting plate can be installed at different heights according to the height of the pregnant woman on site, so as to better limit birthing balls of different specifications. And when the two first limiting plates are installed and used, they are oppositely arranged on both sides of the birthing ball. By using the two oppositely arranged first limiting plates, the birthing ball can be stably restricted therein, so that the birthing ball will not skid no matter how much it is squeezed. And adjusting the installation distance between the two first limiting plates can also make the two first limiting plates better used for limiting birthing balls of different sizes. And by providing the first guiding part, the edge of the first limiting plate is made more smooth, so that the first limiting plate will not scratch the pregnant woman and the birthing ball during use. And the edges of the first limiting plate are all circular, with no obvious sharp corners, and the safety is better. And the combined use of the structures further makes the use effect of the auxiliary limiting mechanism better.

[0019] By arranging a second limiting plate and a reinforcing frame in the auxiliary limiting mechanism, the edges of the second limiting plate are all round, and the arc shape has no obvious edges and corners, which has better safety. In addition, the arrangement of the two second limiting plates can limit the waist of the pregnant woman when she exercises, thereby enhancing the stability of the center of gravity of the pregnant woman during exercise. At the same time, massage convex balls are equidistantly arranged on the side of the second limiting plate close to the delivery ball, and the massage convex balls are made of hollow rubber material, so that the patient can rub and squeeze against the second limiting plate during exercise to massage the patient's waist, thereby enhancing the patient's comfort. Similarly, the third lightweight groove opened on the second limiting plate makes it easier for the second limiting plate to deform under the action of external force, so that the second limiting plate can better provide auxiliary support and massage effect on the waist of the pregnant woman, and the first weakened portion opened in the middle of the second limiting plate further makes the second limiting plate easier to deform when subjected to force. It is easy to produce a stronger deformation from the first weakened part. The fourth installation groove and the fifth lightweight groove are used to quickly adjust the installation position of the second limit plate by using the second installation screw, so that the two oppositely arranged second limit plates can be well fitted to the user's waist when used by patients of different body shapes, so that the second limit plate can better assist the user's limiting support and massage, and the reinforcement frame is set to make the strength of the second limit plate better, thereby enhancing the support and limiting effect of the second limit plate, and the corrugated structure of the reinforcement frame also makes the side of the second limit plate away from the connecting plate have an inward bending tendency, so that the massage convex ball on the second limit plate can better massage the waist of the pregnant woman, wherein the fourth lightweight groove opened on the reinforcement frame makes the deformation trend of the reinforcement frame stronger, and the coordinated use of the structures further makes the use effect of the auxiliary limiting mechanism better.

[0020] By providing a connecting plate in the auxiliary limiting mechanism, the connecting plate can not only be used to connect the two first limiting plates together, but also the connecting plate can produce a certain range of elastic deformation when adjusting the spacing between the first limiting plates, and the shape of the connecting plate is adapted to the delivery ball and the human waist. The second lightweight groove opened on the connecting plate makes it easier for the connecting plate to deform under the action of external force, and the opening of the second lightweight groove reduces the manufacturing cost and quality of the connecting plate. The use of the connecting plate effectively enhances the stability of the device, so that the limiting effect between the structures for the delivery ball and the pregnant woman is better, and the coordinated use of the structures further makes the use effect of the auxiliary limiting mechanism better.

[0021] By providing a backboard within the back support limiting mechanism, not only can the second guiding portion be utilized to further support both sides of the pregnant woman's back when the backboard limits and supports the back of the pregnant woman, but the addition of the second guiding portion enhances the strength at the edges of the backboard, making the backboard's support and limiting effect on the pregnant woman better. Moreover, with the equidistantly arranged bumps, when the backboard comes into contact with the pregnant woman's skin, the bumps contact the pregnant woman's skin and press on it, thereby enabling the backboard to massage the area in contact with the pregnant woman while supporting and limiting her, further improving the usage effect of the backboard, and the coordinated use of the structures further enhances the usage effect of the back support limiting mechanism.

[0022] In summary, through the coordinated use of the auxiliary limiting mechanism, the back support limiting mechanism, and each component within it, the device can not only have a good limiting effect on both the birthing ball and the pregnant woman herself, enhancing the stability of the birthing ball during use, but also ensure that the pregnant woman will not fall during exercise, thus guaranteeing the safety of the pregnant woman and the fetus. At the same time, the device can also assist in massaging the pregnant woman's body during use, further increasing the usage effect of the device, improving the comfort of the pregnant woman during exercise, and also reducing the pregnant woman's anxiety to a certain extent. Additionally, the device has a simple structure, is convenient and fast to use, has good practicality, and low production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] As Figure 1 and Figure 2 shown, an embodiment of the present invention provides a childbirth ball fixing device for free position childbirth, including a mounting plate body 1, a first mounting groove 2 is equidistantly opened on the mounting plate body 1, a suction cup body 3 is installed in the first mounting groove 2, and a limiting strip 4 is installed on the top of the suction cup body 3; an auxiliary limiting mechanism for assisting in limiting the position of a pregnant woman, the auxiliary limiting mechanism is connected to the mounting plate body 1; a back support limiting mechanism for supporting and assisting in limiting the back of the user, the back support limiting mechanism is connected to the auxiliary limiting mechanism.

[0040] This device has two usage states. In the first usage state, the mounting plate body 1 is horizontal to the ground, the suction cup body 3 tightly adheres to the ground of tiles or other smooth surfaces that are easy to adsorb, and the installation height and spacing of the two first limiting plates 7 are adjusted according to the height of the pregnant woman and the size of the childbirth ball, as Figure 4The figure shows the first usage state diagram. The backboard 16 is closely attached to the back of the pregnant woman, and the second limiting plate 13 is closely attached to the buttocks of the pregnant woman. The installation position of the second limiting plate 13 is flexibly adjusted on-site according to the height and body shape of the patient; in the second usage state, the main body 1 of the mounting plate is horizontal to the wall surface, and the suction cup body 3 is adsorbed on the wall surface of tiles or other smooth materials that are easy to adsorb, such as Figure 6 The figure shows the second usage state diagram. At this time, the backboard 16 is closely attached to the buttocks of the pregnant woman, and the second limiting plate 13 is closely attached to the side of the pregnant woman's waist near the thigh. Similarly, the installation position of the second limiting plate 13 is flexibly adjusted on-site according to the height and body shape of the patient.

[0041] By using the auxiliary limiting mechanism, the back support mechanism and the cooperation of each component therein, the device can be flexibly adjusted according to the specific on-site usage conditions, so that the adjusted device can be applicable to the auxiliary movements of the sitting and standing postures of pregnant women. Moreover, the structure effectively enhances the stability of the device, effectively confines the birthing ball within a specific movement space, preventing it from slipping sideways. At the same time, while limiting the birthing ball, it provides auxiliary limiting and supporting effects on the body position of the pregnant woman, effectively preventing the problem of the pregnant woman falling due to unstable center of gravity during exercise. By using the elastic cooperation between the structures, when the birthing ball between the two first limiting plates 7 is squeezed and deformed, the structures will generate corresponding deformation activities along with the deformation of the birthing ball. Thus, the parts of the auxiliary limiting mechanism and the back support limiting mechanism that come into contact with the skin of the pregnant woman not only provide support and limitation to the pregnant woman, but also massage the contact parts, thereby increasing the comfort of the pregnant woman. The cooperation of the structures not only makes the device more practical, but also has a simple structure and is convenient and fast to use. The specific working principles of the above-mentioned auxiliary limiting mechanism, the back support limiting mechanism and each component therein are described in detail below.

[0042] A support rod 5 is fixedly connected to the top of the first installation groove 2. Second installation grooves 6 are equidistantly arranged on the support rod 5. A first installation screw 10 is installed in the second installation groove 6. The limiting strip 4 is made of steel wire, and the suction cup body 3 is made of rubber. The top structure of the suction cup body 3 is adapted to the shape of the first installation groove 2. The mounting plate body 1 is perpendicular to the support rod 5. The first installation screw 10 consists of a screw and a nut. The side of the screw close to the delivery ball is arc-shaped. With this structure, the first limiting plate 7 and the mounting plate body 1 can be connected together by using the support rod 5. Moreover, through the combined use of the second installation groove 6, the first lightweight groove 9 and the first installation screw 10, the first limiting plate 7 can be installed at different heights according to the height of the pregnant woman on site, so as to better limit delivery balls of different specifications. The limiting strip 4 made of steel wire can deform at any angle within a certain range. Therefore, after the suction cup body 3 is installed in the first installation groove 2 by using the limiting strip 4, the suction cup body 3 can be further stably restricted at the required characteristic position in the first installation groove 2 by winding the limiting strip 4, so that the suction cup body 3 will not shift during use. In addition, two support rods 5 are in a group, and a total of four in two groups are evenly distributed on the top of the mounting plate body 1, making the device have better support and stronger stability during use. The combined use of the structures further makes the use effect of the device better, and the structure is simple and convenient to use.

[0043] As Figures 1 to 7 shown, the auxiliary limiting mechanism includes a first limiting plate 7 installed on the top of the mounting plate body 1. First guiding parts 8 are provided on both the top and the bottom of the first limiting plate 7. A connecting plate 11 is installed between the two first limiting plates 7. Second limiting plates 13 are installed on both sides of the connecting plate 11. The two first limiting plates 7 are oppositely arranged on both sides of the delivery ball during installation and use.

[0044] By using the two oppositely arranged first limiting plates 7, the delivery ball can be stably restricted therein, so that the delivery ball will not skid laterally no matter how much extrusion it receives. Moreover, adjusting the installation distance between the two first limiting plates 7 can make the two first limiting plates 7 better used to limit delivery balls of different sizes.

[0045] The connecting plate 11 is used to connect the two first limiting plates 7 together. When adjusting the distance between the first limiting plates 7, the connecting plate 11 can deform elastically within a certain range. With the arrangement of the first guiding parts 8, the edges of the first limiting plates 7 are made smoother, so that the first limiting plates 7 will not scratch the pregnant woman and the delivery ball during use. In addition, the edges of the first limiting plates 7, the connecting plate 11 and the second limiting plates 13 are all circular, and the arc shape has no obvious sharp edges, so the safety is better.

[0046] By providing two second limiting plates 13, the waist of the pregnant woman can be limited during exercise, thereby enhancing the stability of the pregnant woman's center of gravity during exercise. At the same time, massage convex balls are equidistantly arranged on one side of the second limiting plate 13 close to the birthing ball, and the massage convex balls are made of hollow rubber material. When the patient exercises, they rub and squeeze against the second limiting plate 13 to massage the patient's waist, thereby enhancing the comfort of the patient. Moreover, the structure is simple, and the coordinated use of the structures further improves the practicality of the device.

[0047] The first limiting plate 7 is a circular arc structure with a convex middle part. The first limiting plate 7 is equidistantly provided with first lightweight grooves 9. The first limiting plate 7 and the first guiding part 8 are integrally formed. The first limiting plate 7 is made of plastic material. The connecting plate 11 is made of plastic material. The connecting plate 11 is a circular arc structure with a narrow top and a wide bottom. The connecting plate 11 is equidistantly provided with second lightweight grooves 12. The second limiting plate 13 is a circular arc structure adapted to the shape of the pregnant woman's waist. The second limiting plate 13 is made of plastic material. The second limiting plate 13 is equidistantly provided with third lightweight grooves 14. A first weakening part 26 is provided in the middle of the second limiting plate 13. Fourth mounting grooves 24 are equidistantly provided in the middle of the connecting plate 11. Third mounting grooves 23 are equidistantly provided on one side of the second limiting plate 13 close to the connecting plate 11. Second mounting screws 15 are installed in the third mounting grooves 23 and the fourth mounting grooves 24. A second weakening part 27 is provided in the middle of the connecting plate 11. A reinforcing frame 21 is fixedly connected to the top of the second limiting plate 13. Fourth lightweight grooves 22 are equidistantly provided on the reinforcing frame 21. The cross-section of the reinforcing frame 21 is corrugated.

[0048] Through the arc-shaped structure design of the first limiting plate 7, the shape of the first limiting plate 7 can better adapt to the shape of the birthing ball, so that it can produce a better limiting effect on the birthing ball. Moreover, by using the first lightweight grooves 9 provided on the first limiting plate 7, not only the mass of the first limiting plate 7 is reduced, the production cost of the first limiting plate 7 is lowered, but also the first limiting plate 7 is more likely to deform under the action of external forces. And by using the integrally formed structure, the stability of the first limiting plate 7 and the first guiding part 8 is better. At the same time, the cost of the plastic material is lower and it has a certain deformability.

[0049] The shape of the connecting plate 11 is set to fit the childbirth ball and the human waist. The second lightening groove 12 formed on the connecting plate 11 makes the connecting plate 11 more likely to deform under external force, and the formation of the second lightening groove 12 reduces the manufacturing cost and quality of the connecting plate 11. Similarly, the third lightening groove 14 formed on the second limiting plate 13 makes the second limiting plate 13 more likely to deform under external force, so that the second limiting plate 13 can better play an auxiliary supporting and massaging effect on the waist of the pregnant woman. Moreover, the first weakening part 26 formed in the middle of the second limiting plate 13 further makes the second limiting plate 13 more likely to generate a stronger deformation from the first weakening part 26 when stressed.

[0050] The formation of the fourth installation groove 24 and the fifth lightening groove 25 is used to quickly adjust the installation position of the second limiting plate 13 by means of the second installation screw 15. Thus, when used by patients with different body shapes, the two oppositely arranged second limiting plates 13 can closely adhere to the waists of the users, so that the second limiting plate 13 can better assist in the limiting support and massage of the users. By means of the second weakening part 27 formed on the connecting plate 11, when the pregnant woman relies on the back plate 16 and the back plate 16 approaches the connecting plate 11, the connecting plate 11 can first deform from the second weakening part 27 when stressed. Thus, the back plate 16 and the connecting plate 11 play a good role in supporting, limiting and massaging the patient.

[0051] By means of the arrangement of the reinforcing frame 21, the strength of the second limiting plate 13 is better, thus enhancing the supporting and limiting effects of the second limiting plate 13. Moreover, the corrugated reinforcing frame 21 also makes the side of the second limiting plate 13 away from the connecting plate 11 have a tendency to bend inward, so that the massage convex balls on the second limiting plate 13 can better massage the waist of the pregnant woman. The fourth lightening groove 22 formed on the reinforcing frame 21 makes the deformation tendency of the reinforcing frame 21 stronger. The structure is simple, and the combined use of the structures further makes the use effect of the auxiliary limiting mechanism better. The specific structure and working principle of the above-mentioned back plate 16 are described in detail below.

[0052] Such as Figures 1 to 7As shown in the figure, the back support and limit mechanism includes a back plate 16 installed on the connecting plate 11. A bump 19 is provided on the outer wall of the side of the back plate 16 away from the connecting plate 11. Second guiding parts 17 are fixedly connected to both sides of the back plate 16. The back plate 16 and the second guiding parts 17 are integrally formed structures. Through the integrally formed structure, the stability between the back plate 16 and the second guiding parts 17 is better. By using the setting of the second guiding parts 17, when the back plate 16 limits and supports the back of a pregnant woman, the second guiding parts 17 further support both sides of the back of the pregnant woman. The addition of the second guiding parts 17 enhances the strength at the edge of the back plate 16, making the support and limit effect of the back plate 16 on the pregnant woman better. And by using the equidistantly arranged bumps 19, when the back plate 16 contacts the skin of the pregnant woman, the bumps 19 contact the skin of the pregnant woman and press on the skin of the pregnant woman, so that while the back plate 16 supports and limits the pregnant woman, it can also massage the parts in contact with the pregnant woman, thereby making the use effect of the back plate 16 better. The structure is simple, and the combined use of the structures further makes the use effect of the back support and limit mechanism better, and the production cost of the structure is relatively low, which is convenient for popularization and use.

[0053] The back plate 16 is a circular arc structure adapted to the shape of the human back. A buffer cavity 18 is opened in the second guiding part 17. Fifth lightening grooves 25 are equidistantly opened on the back plate 16. Connecting blocks 20 are fixedly connected to both sides of the bottom of the back plate 16. Through the design of the arc structure of the back plate 16, the back plate 16 can closely fit the back of the pregnant woman during use, so that the back plate 16 can better support, limit and massage the back of the pregnant woman. And by using the opened buffer cavity 18, the second guiding part 17 can produce a certain buffering effect when being squeezed. And by using the opened fifth lightening grooves 25, the back plate 16 is more likely to deform under the action of external force, and effectively reduces the mass of the back plate 16, reducing the production cost of the back plate 16. And by using the setting of the two connecting blocks 20, the back plate 16 and the connecting plate 11 are connected together. And through the connection of the connecting blocks 20, the bottom of the back plate 16 has better deformation ability. And the structure is simple, and the combined use of the structures further makes the use effect of the back support and limit mechanism better.

[0054] The working principle of the technical solution provided by the present invention is as follows:

[0055] During use, the device has two usage states. In the first usage state, the mounting plate body 1 is horizontal to the ground, and the suction cup body 3 tightly adsorbs on the ground of tiles or other smooth materials that are easy to adsorb. Adjust the installation height and spacing of the two first limit plates 7 according to the height of the pregnant woman and the size of the delivery ball. For example Figure 4The following is a diagram of the first usage state. The backboard 16 is closely attached to the back of the pregnant woman, and the second limiting plate 13 is closely attached to the buttocks of the pregnant woman. The installation position of the second limiting plate 13 is flexibly adjusted on-site according to the height and body shape of the patient; in the second usage state, the main body 1 of the mounting plate is horizontal to the wall surface, and the suction cup body 3 is adsorbed on the wall surface of tiles or other smooth materials that are easy to adsorb, such as Figure 6 The following is a diagram of the second usage state. At this time, the backboard 16 is closely attached to the buttocks of the pregnant woman, and the second limiting plate 13 is closely attached to the side of the pregnant woman's waist near the thigh. Similarly, the installation position of the second limiting plate 13 is flexibly adjusted on-site according to the height and body shape of the patient.

[0056] During use, first select the exercise posture. For example, if the user selects a sitting position to use the surgical instrument, then first install the first limiting plate 7 at the corresponding height of the support rod 5 according to the specific on-site usage situation, and use the first mounting screw 10 to pass through the second mounting groove 6 and the first lightweight groove 9 to fix the relative positions of the first limiting plate 7 and the support rod 5. After installing the first limiting plate 7, place the required delivery ball between the two oppositely placed first limiting plates 7. Subsequently, adjust the distance between the two first limiting plates 7. The connecting plate 11 is used to connect the two first limiting plates 7 together. When adjusting the distance between the first limiting plates 7, the connecting plate 11 can produce a certain range of elastic deformation. After adjusting until the delivery ball is within the optimal movement range, make the main body 1 of the mounting plate horizontal to the ground. The top of the suction cup body 3 passes through the first mounting groove 2, and the limiting strip 4 is used to fix the suction cup body 3 on the main body 1 of the mounting plate. A card slot adapted to the shape of the limiting strip 4 is provided at the top of the suction cup body 3. After the limiting strip 4 is wound into the card slot, an external force is applied to make it bend and deform so as to limit the top of the suction cup body 3. Then make the suction cup body 3 tightly adsorb on the ground of tiles or other smooth materials that are easy to adsorb. Then, according to the body shape of the patient, after adjusting the second limiting plate 13 to the required position, pass the second mounting screw 15 through the fourth mounting groove 24 and the fifth lightweight groove 25 to quickly and stably fix the second limiting plate 13 to the side of the connecting plate 11. The combined use of the structures can closely adhere to the user's waist well when patients of different body shapes use it, so that the second limiting plate 13 can better assist the user in limiting support and massage.

[0057] After the second limiting plate 13 is installed, the pregnant woman sits on the delivery ball inside the two first limiting plates 7, and then squeezes the delivery ball up and down, or rotates. During the exercise, the pregnant woman's back is close to the back plate 16, and the two second limiting plates 13 are located on both sides of the pregnant woman's waist. The two second limiting plates 13 can be used to limit the pregnant woman's waist when she exercises, thereby enhancing the stability of the pregnant woman's center of gravity during exercise. At the same time, massage convex balls are equidistantly arranged on one side of the second limiting plate 13 close to the delivery ball, and the massage convex balls are made of hollow rubber material, so that the patient rubs and squeezes against the second limiting plate 13 during exercise, and massages the patient's waist, thereby enhancing the patient's comfort. During the exercise of the pregnant woman, the back is squeezed and rubbed against the back plate 16 and the convex blocks 19 thereon, and the waist on both sides and the back waist are squeezed and rubbed against the second limiting plates 13. The coordinated use of the structures makes the pregnant woman have better stability and higher comfort during exercise.

[0058] The arc-shaped structural design of the first limiting plate 7 in the above structure allows the shape of the first limiting plate 7 to be better adapted to the shape of the delivery ball, so that it can have a better limiting effect on the delivery ball, and the first lightweight groove 9 opened on the first limiting plate 7 not only reduces the weight of the first limiting plate 7, but also reduces the production cost of the first limiting plate 7, and makes the first limiting plate 7 easier to deform when subjected to external force, and the integrated structure is used to make the first limiting plate 7 and the first guide part 8 more stable, and the plastic material is relatively low in cost and has a certain degree of deformability, the shape of the connecting plate 11 is adapted to the delivery ball and the human waist, and the second lightweight groove 12 opened on the connecting plate 11 makes it easier for the connecting plate 11 to deform when subjected to external force, and The opening of the second lightweight groove 12 reduces the manufacturing cost and quality of the connecting plate 11. Similarly, the third lightweight groove 14 opened on the second limiting plate 13 makes it easier for the second limiting plate 13 to deform under the action of external force, so that the second limiting plate 13 can better provide auxiliary support and massage effects on the waist of the pregnant woman. The first weakened portion 26 opened in the middle of the second limiting plate 13 further makes it easier for the second limiting plate 13 to produce stronger deformation from the first weakened portion 26 when subjected to force. The second weakened portion 27 opened on the connecting plate 11 allows the pregnant woman to lean on the back plate 16 and bring the back plate 16 close to the connecting plate 11. When the connecting plate 11 is subjected to pressure, it can first be deformed from the second weakened portion 27, so that the back plate 16 and the connecting plate 11 can provide good support, limitation and massage effects for the patient.

[0059] With the arrangement of the reinforcing frame 21, the strength of the second limiting plate 13 is better, thus enhancing the supporting and limiting effects of the second limiting plate 13. Moreover, the corrugated reinforcing frame 21 also makes the side of the second limiting plate 13 away from the connecting plate 11 have an inward bending tendency, so that the massage convex balls on the second limiting plate 13 can massage the waist of the pregnant woman better. The fourth lightweight groove 22 opened on the reinforcing frame 21 makes the deformation tendency of the reinforcing frame 21 stronger. The structure is simple, and the combined use of the structures further makes the use effect of the auxiliary limiting mechanism better. And through the integral structure, the stability between the back plate 16 and the second guiding part 17 is better. With the arrangement of the second guiding part 17, when the back plate 16 limits and supports the back of the pregnant woman, the second guiding part 17 further supports both sides of the back of the pregnant woman. The addition of the second guiding part 17 enhances the strength at the edge of the back plate 16, making the supporting and limiting effect of the back plate 16 on the pregnant woman better. And with the equidistantly arranged bumps 19, when the back plate 16 contacts the skin of the pregnant woman, the bumps 19 contact the skin of the pregnant woman and press on the skin of the pregnant woman, so that the back plate 16 can massage the part in contact with the pregnant woman while supporting and limiting the pregnant woman, and further makes the use effect of the back plate 16 better. Through the arc-shaped structure design of the back plate 16, the back plate 16 can closely fit the back of the pregnant woman during use, so that the back plate 16 can better support, limit and massage the back of the pregnant woman.

[0060] With the opening of the buffer cavity 18, the second guiding part 17 can produce a certain buffering effect when being squeezed. And with the opening of the fifth lightweight groove 25, the back plate 16 is more likely to deform under the action of external force, effectively reducing the mass of the back plate 16 and the production cost of the back plate 16. And with the arrangement of the two connecting blocks 20, the back plate 16 and the connecting plate 11 are connected together. And with the connection of the connecting blocks 20, the bottom of the back plate 16 has better deformation ability. And the structure of the device is simple, with good practicability and is convenient to use.
