Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and specifically relates to an auxiliary positioning bed for intraspinal analgesia during painless labor. Background Art

[0002] The promotion of painless childbirth is of great significance for improving the childbirth experience of mothers, alleviating pain during childbirth, reducing the risk of complications for mothers and newborns, and improving the safety and success rate of childbirth.

[0003] During painless delivery, the mother needs to lie on the painless delivery assisted bed to receive spinal analgesia before lying on the delivery bed. The spinal puncture process takes at least 30 minutes. During the puncture process, the mother needs to be in an arched position so that the intervertebral distance at the puncture site can be expanded to facilitate accurate and smooth puncture. However, due to the large belly of the mother, it is difficult for the mother to put herself in the arched position; at the same time, during the puncture process, the mother will experience uterine contraction pain, and it is difficult to maintain the arched posture, so the puncture cannot be performed or the puncture is inaccurate. Summary of the invention

[0004] In view of the above analysis, an embodiment of the present invention aims to provide an auxiliary positioning bed for spinal analgesia during painless delivery, so as to solve the problem that the body position of the parturient is difficult and easy to change when receiving spinal analgesia during painless delivery.

[0013] Furthermore, the inner pad is fixedly connected to the supporting unit.

[0014] Furthermore, it also includes a fourth limiting unit, which is fixed on the first limiting unit and is used for the parturient to actively limit her body through her arms.

[0015] Furthermore, the fourth limiting unit includes a limiting rod for the parturient's hand to pull.

[0016] Furthermore, the fourth limiting unit also includes a limiting column, which is used for the mother's arms to hold.

[0017] Furthermore, it also includes a third limiting unit, which includes an arc-shaped limiting pad, which is connected to the second limiting pad and is used to limit the waist and abdomen of the parturient.

[0018] Furthermore, one side of the arc-shaped limiting pad is rotatably connected to one side of the second limiting member, and the other side of the arc-shaped limiting pad is provided with a locking assembly.

[0021] Furthermore, the limiting pad is located above the side-lying pad and is slidably connected to the second limiting unit.

[0022] Furthermore, the driving mechanism can drive the limiting pad to flip to both sides.

[0023] Furthermore, the outer pad and the inner pad are movably connected.

[0024] Furthermore, one side of the inner pad is rotatably connected to one side of the working window via a rotating shaft, and a folding bracket is provided at the bottom of the inner pad.

[0028] Furthermore, the slide plate is provided with a screw block, and the second screw rod is installed in the threaded through hole of the screw block.

[0029] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0030] (1) The auxiliary positioning bed of the present invention has a structure in which the upper surface of the inner pad is lower than the upper surface of the outer pad. The doctor does not need to manually position the body of the parturient. The parturient only needs to lie naturally on the device, and the parturient's posture can be naturally and passively limited by the effect of gravity. This is simple and easy to use, which not only saves the doctor's time and physical strength, but also does not need to rely on the parturient's repeated cooperation, so that the parturient's emotions and psychology will not be affected.

[0031] (2) The auxiliary positioning bed of the present invention, by setting four limiting units, can assist the parturient to form a side-lying posture with legs curled up and waist arched and maintain it during the analgesia process, so that the anesthesiologist can smoothly implement spinal analgesia on the parturient and maintain the position of the puncture needle during the spinal analgesia process, so as to smoothly and uninterruptedly complete the spinal analgesia process of painless delivery and achieve the expected effect of spinal analgesia.

[0032] (3) The auxiliary positioning bed of the present invention, by arranging a driving mechanism on the first limiting unit, can enable the parturient to turn over to a side-lying position while maintaining the naturally curled-up leg and arched waist posture when lying flat, so that the parturient can achieve the posture required for intrathecal analgesia without the parturient's active cooperation. At the same time, when the parturient feels uncomfortable due to lying on the side for a long time, the first limiting unit can be appropriately rotated to change the gravity on the parturient, and at the same time relieve the pressure on one side of the parturient's body, so as to effectively alleviate the parturient's discomfort and improve the parturient's psychological and physical freedom and comfort.

[0033] (4) The auxiliary positioning bed of the present invention, by providing a third limiting unit, can gently and effectively limit the abdomen of the parturient, effectively prevent the abdomen from moving forward when lying on the side, avoid the position change of the puncture needle, and ensure the analgesic effect.

[0034] (5) The auxiliary positioning bed of the present invention, by arranging a plurality of flexible protrusions on the third limiting unit, can not only enable the arc-shaped limiting pad to gently massage the abdomen, but also enable the arc-shaped limiting pad to limit the abdomen to play a buffering role, thereby avoiding hard squeezing of the abdomen, and can also adapt to abdomens of different shapes. At the same time, the gaps between the gill structures can also keep the abdomen in contact with the air, so that the abdomen of the parturient will not feel stuffy.

[0035] (6) The auxiliary positioning bed of the present invention, by providing the fourth limiting unit, can not only enable the parturient to perform active limiting conveniently and labor-savingly, but also increase the parturient's sense of security.

[0036] (7) The second limiting member of the present invention, by providing a structure in which the outer pad and the inner pad are movably connected, can provide support and protection for the waist and back of the parturient, thereby improving the safety of the intrathecal analgesia process.

[0037] (8) The auxiliary positioning bed of the present invention can reduce the overall width of the device by arranging the limiting pad above the side-lying pad and slidably connecting it to the second limiting unit, thereby saving operating space and facilitating the movement of the device.

[0038] (9) The second driving mechanism of the present invention can drive the limiting pad to flip to both sides, so that the doctor can set the direction of the parturient's side-lying position according to the parturient's habits and needs, so that the parturient can experience the considerate care, so that she can smoothly cooperate and successfully complete the entire process of intrathecal analgesia.

[0039] (10) The present invention can achieve the effect of positioning the body of parturients of different heights by providing a screw-type first adjustment member, making the parturients more comfortable when positioning.

[0040] (11) The present invention can adjust the curvature of the surface of the first limiting pad by providing a screw-type second adjusting member, so that the thoracic spine of the parturient remains curved.

[0041] In the present invention, the above-mentioned technical solutions can also be combined with each other to achieve more preferred combination solutions. Other features and advantages of the present invention will be described in the following content, and some advantages can be obvious from the description or understood by practicing the present invention.

DETAILED DESCRIPTION

[0055] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0056] Example 1

[0057] A specific embodiment of the present invention, as Figure 1 and Figure 2As shown, an auxiliary positioning bed for intrathecal analgesia for painless delivery is disclosed. The auxiliary positioning bed is used for the parturient to lie on before lying on the delivery bed during the painless delivery process, so as to assist the parturient to form a side-lying posture with curled legs and bent waist and keep it unchanged during the puncture process, so that the anesthesiologist can smoothly implement intrathecal analgesia for the parturient, and the intrathecal puncture process of painless delivery can be completed smoothly and uninterruptedly, thereby achieving the expected effect of intrathecal analgesia.

[0058] The auxiliary positioning bed of the present invention comprises a first limiting unit 1, a second limiting unit 2, a third limiting unit 3, a fourth limiting unit 4 and a supporting unit 5. Figure 1 The support unit 5 is located at the lower part of the auxiliary device. Optionally, the support unit 5 is a bed frame, including a vertical support component 51 and a horizontal support component 52, which are used to support and fix other functional units of the auxiliary positioning bed.

[0059] The first limiting unit 1 includes a limiting pad and a driving mechanism 14, and the second limiting unit 2 includes a side-lying pad. The limiting pad and the side-lying pad are arranged side by side above the horizontal supporting member 52 to form a mattress located on the supporting unit 5. The side-lying pad is a fixed member, which is fixedly connected to the horizontal supporting member 52; the limiting pad is a movable member, including a first limiting pad 11, a second limiting pad 12 and a third limiting pad 13, as shown in FIG. Figure 1 As shown in FIG. 1 , the third limiting pad 13 supports the upper body, waist and back, and lower body of the parturient when she lies flat. Figure 2 As shown, the lower limb limiter 131 can be bent to form a middle bulge, which is used to support the leg fossa of the parturient, so that the lower limbs of the parturient can keep the legs curled up, so that the lumbar vertebrae that need to be punctured can protrude backwards, which is convenient for implementing intraspinal analgesia; the driving mechanism 14 can drive the first limit pad 11, the second limit pad 12 and the third limit pad 13 as a whole, as shown in FIG. Fig.10 As shown, the side-lying cushion rotates around the side adjacent to the first limiting unit 1, so that the body of the parturient can passively lie on the second limiting unit 2.

[0060] A pillow pad 111 is provided at one end of the first limiting pad 11. Figure 2 As shown, it is used to support the head and neck of the parturient, which can not only make the parturient feel comfortable, but also limit the parturient's shoulders to prevent the body from moving toward the head when the parturient's lower body is lifted.

[0061] The second limiting pad 12 is used to limit the lumbar spine of the parturient. The upper surface of the second limiting pad is curved, so that the lumbar spine of the parturient is in a state of natural backward bending when the parturient lies flat. In order to enable the parturient to expose her waist and back when lying on her side, the second limiting pad 12 includes an outer pad 121 and an inner pad 122, as shown in FIG. Figure 2As shown. The outer pad 121 is a frame component located around the second limiting pad 12, with a hollow working window 1211 in the middle. One side of the outer pad 121 is fixedly connected to the first limiting pad 11, and the other side is rotatably connected to the third limiting pad 13; the inner pad 122 is a square pad located in the middle of the outer pad 121, fixed on the horizontal support component 52, and the outer side wall of the inner pad 122 matches the working window 1211. When the inner pad 122 is tightly attached to the outer pad 121, the upper surface of the inner pad 122 is lower than the upper surface of the outer pad 121. When the parturient lies flat on the first limiting unit 1, due to the lower upper surface of the inner pad 122, the lumbar vertebrae protrude toward the inner pad 122 through the working window 1211 under the action of gravity, achieving a natural passive limiting posture. At the same time, the support of the inner pad 122 also prevents the parturient from feeling uncomfortable due to excessive bending of the waist. When the first limiting unit 1 rotates, the inner pad 122 is fixed. When the first limiting unit 1 is rotated into place, the parturient is in a side-lying position, and the part of the waist and back located in the working window 1211 is exposed, which is convenient for the doctor to perform intraspinal puncture in the waist and back of the parturient.

[0062] The third limiting pad 13 is used to limit the lower limbs of the parturient. For example, a foot pedal 132 is provided at one end of the third limiting pad 13 away from the second limiting pad 12. Figure 2 As shown, it is convenient for parturients to place their feet. The footrest 132 can be extended and fixed after extension, so that parturients with different leg lengths can comfortably place their feet on the footrest 132.

[0063] like Figure 1 and Figure 3 As shown, the third limiting unit 3 is used to perform passive and flexible limiting on the abdomen of the parturient, and includes an arc-shaped limiting pad 31, and the distance between the two sides of the arc-shaped limiting pad 31 is the same as the width of the second limiting pad 12. One side of the arc-shaped limiting pad 31 is rotatably connected to one side of the second limiting pad 12, and the other side is provided with a locking assembly 32, so that the arc-shaped limiting pad 31 can be closed, locked or opened with the second limiting pad 12. The inner side of the arc-shaped limiting pad 31 is made of fluffy and soft material, and the outer side is made of harder material, so that the abdomen of the parturient can be gently and effectively limited to prevent the abdomen from moving forward when lying on the side, and to avoid changes in the puncture posture. The arc-shaped limiting pad 31 can also be detachably connected to the second limiting pad 12, and installed according to the side-lying position of the parturient to ensure that the waist on the side lying is completely covered.

[0064] like Figure 1 and Figure 4As shown, the parturient actively limits the position by pulling the fourth limiting unit 4 with her arms, and the fourth limiting unit 4 includes a limiting rod 41 and a limiting column 42. Exemplarily, the fourth limiting unit 4 is rotatably connected to the first limiting pad 11, and the limiting rod 41 is located on both sides of the limiting column 42. Before use, the fourth limiting unit 4 is rotated to one side of the first limiting pad 11. When the parturient lies flat on the first limiting unit 1, the fourth limiting unit 4 is rotated so that the limiting rod 41 and the limiting column 42 are located above the first limiting pad 11, so that the parturient can lie on the first limiting pad 11 and actively keep the body curled up by grabbing with her hands. In order to facilitate gripping, the surface of the limiting rod 41 is provided with an anti-slip convex-concave structure, and a material with high friction can also be used. In order to prevent the parturient's hands from slipping when sweating, a sweat-absorbing anti-slip material can also be used.

[0065] Considering that it is difficult for the parturient to maintain a posture with her arms, a limiting column 42 is fixed in the middle of the limiting rod 41, so that the parturient can also change to a posture of hugging the limiting column 42 with her arms to implement active limiting. The center of the limiting column 42 is made of hard material, and the surface of the opposite side of the first limiting pad 11 is covered with soft material, which can facilitate the parturient to hold the limiting column 42 while the chest or head can be against the limiting column 42, increasing the comfort and sense of security of the parturient.

[0066] In order to make the active limiting function more effective and comfortable, the side of the limiting column 42 that contacts the arm is set to a smooth concave surface, so that when the parturient hugs the limiting column 42, both arms can fit into the smooth concave surface, so that the arms can be stably placed on the limiting column 42 without having to hug tightly, saving the parturient's energy.

[0067] In order to prevent the fourth limiting unit 4 from affecting the lying-down of the parturient, the limiting rod 41 can be detachably connected or rotatably connected to the first limiting pad 11, and can also be set as a telescopic lifting structure, and the position of the limiting rod 41 is fixed after the parturient lies flat on the first limiting pad 11. The telescopic lifting limiting rod 41 can also be adjusted to the most comfortable height for the parturient according to the body posture of the parturient.

[0068] When implementing intraspinal analgesia, the parturient first lies flat on the first limiting unit 1, with the upper body, middle body and lower body corresponding to the first limiting pad 11, the second limiting pad 12 and the third limiting pad 13 respectively, especially the middle waist and back need to be located on the second limiting pad 12, so that the waist and back will form a natural bending state under the action of gravity. Then, after the doctor instructs the parturient to hold the limiting rod 41 or hug the limiting column 42, the doctor rotates the arc limiting pad 31 on the second limiting unit 2. When the inner wall of the arc limiting pad 31 fits the abdomen of the parturient, the other side of the arc limiting pad 31 is locked with the locking assembly 32, so that the relative position between the arc limiting pad 31 and the second limiting pad 12 is fixed. Finally, the doctor operates the driving mechanism 14 to slowly rotate the limiting pad and the third limiting unit 3 in the direction of the second limiting unit 2 until the parturient is in a comfortable side-lying position.

[0069] The auxiliary positioning bed of this embodiment does not require the doctor to manually position the body of the parturient. The parturient only needs to lie naturally on the bed. Through the action of the first limiting unit 1, the second limiting unit 2 and gravity, the position of the parturient can be naturally and passively limited. It is simple and easy to operate, which not only saves the doctor's time and physical strength, but also does not need to rely on the repeated cooperation of the parturient, so that the parturient's emotions and psychology will not be affected. In addition, when the parturient feels uncomfortable due to lying on the side for a long time, the doctor can also appropriately rotate the first limiting unit 1 to change the gravity on the parturient, and at the same time relieve the pressure on one side of the parturient's body, which can effectively relieve the discomfort of the parturient and improve the psychological and physical freedom and comfort of the parturient. At the same time, by setting the fourth limiting unit 4, this embodiment can not only enable the parturient to perform active limiting conveniently and labor-savingly, but also increase the parturient's sense of security.

[0070] Further, such as Figure 3 As shown, the center of the arc-shaped limiting pad 31 is an abdominal limiting plate 311, and the abdominal limiting plate 311 is a protruding circular guard plate used to limit the protruding position of the abdomen of the parturient. The inner wall of the arc-shaped limiting pad 31 is regularly provided with a plurality of flexible protrusions 312. Preferably, the flexible protrusions 312 are flexible convex strips, which can be straight lines, curves or rings, like the structure of the gills on the inner side of the mushroom cap, and can also be hemispherical, arc-shaped, etc. The plurality of flexible protrusions 312 can not only enable the arc-shaped limiting pad 31 to gently massage the abdomen, but also enable the arc-shaped limiting pad 31 to buffer the position of the abdomen, avoid hard squeezing of the abdomen, and can also adapt to abdomens of different shapes. At the same time, the gaps between the gill structures can also keep the abdomen in contact with the air, so that the abdomen of the parturient will not feel stuffy.

[0071] Furthermore, due to the low temperature in the delivery room, the maternal skin is exposed over a large area, which often results in loss of body temperature and discomfort to the maternal body. Considering that the maternal back is exposed, the inner wall of the arc-shaped limit pad 31 is also provided with a heat preservation component 313 and a temperature measuring probe. Optionally, the heat preservation component 313 uses a graphene heating sheet, and the heat preservation component 313 can be appropriately heated according to the temperature measured by the temperature measuring probe, so as to keep the maternal side waist and abdomen warm and reduce the maternal discomfort.

[0072] Furthermore, the arc-shaped limiting pad 31 also includes a damping shaft 314, such as Figure 3 As shown, the arc-shaped limiting pad 31 and the second limiting pad 12 are rotatably connected via a damping shaft 314, so that when the arc-shaped limiting pad 31 is opened on the second limiting pad 12, it can be conveniently stopped at any angle, thereby improving the convenience and safety of operation.

[0073] Furthermore, the locking assembly 32 is provided with a plurality of locking gears, so that the space between the arc-shaped limiting pad 31 and the second limiting pad 12 can be adjusted, which can not only adapt to the waist and abdomen circumferences of different sizes of parturients, but also adjust the tightness of the abdominal limit according to the comfort of the parturient.

[0074] Optionally, the driving mechanism 14 can be set as a manual mechanical structure, and an electric control mechanism can also be used. The manually controlled and electrically controlled lifting and flipping mechanisms are both existing technologies and are not within the scope of protection of this application.

[0075] Example 2

[0076] The auxiliary positioning bed of this embodiment is different from that of embodiment 1 in that Figure 5 As shown, the first limiting unit 1 also includes an adjusting mechanism 16, which can adjust the distance between the pillow pad 111 and the second limiting pad 12, and can not only adjust the curvature of the thoracic spine of the parturient.

[0077] Specifically, the adjustment mechanism 16 is installed in the installation cavity inside the first limiting pad 11, and includes a first adjustment member 161 and a second adjustment member 162. The first adjustment member 161 is used to adjust the distance between the pillow pad 111 and the second limiting pad 12 to accommodate parturients of different heights. The second adjustment member 162 is used to adjust the protruding height of the pillow pad 111 to adjust the inner bending angle of the parturient's upper body.

[0078] like Figure 6 and Figure 7As shown, the first adjusting member 161 includes a slide plate 1611, a first screw rod 1612 and a first knob 1613 connected in sequence; the axis of the first screw rod 1612, the symmetry plane of the first limiting pad 11 and the symmetry plane of the first limiting unit 1 are coplanar, and two T-shaped slide grooves 16111 are symmetrically arranged on the slide plate 1611, and the T-shaped slide grooves 16111 are parallel to the first screw rod 1612. The bottom plate of the first limiting pad 11 is provided with a slide rail matching the T-shaped slide groove 16111 and a screw hole matching the first screw rod 1612. The first knob 1613 is located outside the first limiting pad 11.

[0079] like Figure 6 As shown, the second adjusting member 162 includes an adjusting plate 1621, a second screw rod 1622 and a second knob 1623 connected in sequence. One end of the second screw rod 1622 passes through the slide plate 1611 and is rotatably connected to the center of the adjusting plate 1621 through a bearing. The other end of the second screw rod 1622 is fixed with a second knob 1623. Considering the stability of the connection between the second screw rod 1622 and the slide plate 1611, the slide plate 1611 includes a screw block 16112 with a threaded through hole in the center. The second screw rod 1622 is matched and installed with the threaded through hole of the screw block 16112. The screw block 16112 is arranged in two T-shaped slots 16111. The adjusting plate 1621 is located below the pillow pad 111 on the first limiting pad 11, and the second knob 1623 protrudes from the first limiting pad 11.

[0080] Due to the differences in height among mothers, when the position of the pillow 111 needs to be adjusted, the first knob 1613 is rotated to make the adjustment mechanism 16 move linearly in the first limiting pad 11, thereby adjusting the distance between the pillow 111 and the second limiting pad 12, thereby meeting the purpose of ensuring that the pillow 111 can be positioned at the neck for mothers of different heights.

[0081] In order to enable the thoracic spine of the parturient to maintain the arched posture during puncture, the second knob 1623 is rotated to increase the distance between the adjustment plate 1621 and the slide plate 1611, thereby gradually pushing the upper surface of the first limiting pad 11 close to and fit the back of the parturient, so as to keep the thoracic spine of the parturient in a bent posture.

[0082] Further, such as Figure 8 As shown, a plurality of elastic slats 16211 are provided on the adjustment plate 1621. Since the elastic slats 16211 can be elastically deformed and the soft pad is provided on the upper surface of the first limiting pad 11, when the thoracic spine of the parturient is limited, the parturient will not feel a hard sense of pressure.

[0083] It should be noted that, in order to allow the upper surface of the first limiting pad 11 to bend, the side surface of the first limiting pad 11 is a folding structure or the bottom and upper soft pad of the first limiting pad 11 are set as a split structure at one end.

[0084] Furthermore, the present embodiment is different from the embodiment 1 in that the outer pad 121 and the inner pad 122 of the second limiting pad 12 are movably connected. Figure 5 As shown, when the limiting unit rotates to the side-lying position, the outer pad 121 drives the inner pad 122 to move together. Once the parturient's upper body protrudes too far backward from the working window 1211 due to uterine contractions, the inner pad 122 can block the parturient's waist and back, preventing the parturient from drilling out of the working window 1211 and falling.

[0085] like Fig. 9 As shown, illustratively, one side of the inner pad 122 close to the second limiting unit 2 is rotatably connected to the outer pad 121 via a rotating shaft 123, and the back of the inner pad 122 is connected to a folding bracket 124. When the second limiting pad 12 is in a lying state, the folding bracket 124 is folded; when the second limiting pad 12 is rotated to the side-lying position, the inner pad 122 rotates synchronously with the second limiting pad 12, which plays a role in protecting and limiting the waist and back of the parturient. After the second limiting pad 12 is rotated to the side-lying position, the folding bracket 124 is opened and the inner pad 122 is rotated, and the working window 1211 is opened to expose the puncture site of the parturient, so as to facilitate the doctor to implement spinal analgesia.

[0086] Furthermore, the horizontal support member 52 is provided with a plurality of slots (not shown in the figure), which enable the folding bracket 124 to support the inner pad 122 at a plurality of angles. Preferably, when implementing intraspinal analgesia, the folding bracket 124 can lock the inner pad 122 at a position where the angle between the inner pad 122 and the outer pad 121 is 60 degrees, so that once the lower back of the parturient falls out of the working window 1211, the inner pad 122 can safely receive the inner pad 122.

[0087] Example 3

[0088] The auxiliary positioning bed of this embodiment is different from that of embodiment 2 in that: Fig.10 As shown, the limiting pad of the first limiting unit 1 is located above the side lying pad of the second limiting unit 2, and the first limiting unit can move along the width direction of the second limiting unit 2, while the driving mechanism 14 drives the first limiting unit 1 to rotate. The width of the auxiliary positioning bed of this embodiment can be the same as that of a standard bed, which saves more space.

[0089] Exemplarily, the driving mechanism 14 includes two electric telescopic rods, which are respectively fixed on one side of the two ends of the support unit 5, and the driving ends of the two electric telescopic rods are respectively connected to the connecting parts 15 at the two ends of the first limiting unit 1. Both ends of the second limiting unit 2 are provided with linear limiting grooves 21, and the linear limiting grooves 21 are in the shape of an inverted "T", and the upper part of the linear limiting grooves 21 is open; the four corners of the bottom of the first limiting unit 1 are provided with pulleys 112 matching the linear limiting grooves 21, and the pulleys 112 are hinged to the first limiting unit 1. When the driving mechanism 14 drives the limiting pad to rotate to one side, the pulley 112 on the same side slides on the linear limiting groove 21, so that while the limiting pad rotates, one side of the limiting pad always moves horizontally on the second limiting unit 2 to ensure that when the parturient rotates to the side-lying position, she can lie on her side on the second limiting unit 2.

[0090] The auxiliary positioning bed of this embodiment overlaps the limiting pad and the side-lying pad to reduce the overall width of the bed, saving operating space and facilitating the movement of the bed. The driving mechanism 14 is arranged at both ends of the supporting unit 5, which can avoid the driving mechanism 14 from blocking the waist and back of the parturient, making it easier for the doctor to operate.

[0091] Furthermore, the two electric telescopic rods of the driving mechanism 14 are respectively fixed in the middle of the two ends of the supporting unit 5, and the two ends of the first limiting unit 1 are provided with two connecting parts 15, which are respectively located on both sides of the first limiting unit 1, and the driving ends of the two electric telescopic rods can be switched between the connecting parts 15 on both sides. The doctor can set the direction of the side-lying position of the parturient according to the habits and needs of the parturient, so that the parturient can experience the consideration, so as to smoothly cooperate and smoothly adhere to the whole process of spinal analgesia.

[0092] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
