[0018] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Embodiment 1: A delivery bed for obstetric care, referring to Figure 1-Figure 3 As shown, it includes: a bed body 1, which is provided with rollers, an adjustable backrest and a folding guardrail; a fixing sleeve 11, which has two and is fixed to the bed body 1; a fixing rod 12, which has two and is arranged on an adjacent fixing sleeve 11; a first rotating frame 13, which has two and is rotatably arranged on an adjacent fixing rod 12; a first sliding column 14, which has two and is arranged on an adjacent first rotating frame 13, and the first sliding column 14 is provided with a support frame 15, and a Velcro is installed on the support frame 15; a support plate 16, which has two, and the two support plates 16 are plug-in installed on the bed body 1, and the disassembly arrangement of the support plate 16 is used to adapt to different delivery positions and operation requirements; a stabilizing mechanism, which is arranged on the bed body 1, and the stabilizing mechanism is used to improve the stability of the bed body 1; a limiting mechanism, which has two and is arranged on adjacent fixing rods 12, and the limiting mechanism is used to limit the movement of adjacent fixing rods 12.

[0020] In the above scheme, the bed body 1 is connected to the bed board through a hydraulic lifting structure, and the height of the bed board is adjusted by the hydraulic lifting structure to facilitate the parturient to get on the bed. The foldable guardrail on the bed body 1 is used to protect the parturient thereon. The rollers on the bed body 1 are convenient for transferring pregnant women. At the same time, a braking structure is provided at the rollers on the bed body 1 to keep the bed body 1 stable relative to the ground. The upper surface of the support plate 16 is provided with a plug hole for installing the guardrail (the guardrail is shown in the figure). The detachable design of the support plate 16 combines the functions of the delivery bed and the midwifery bed. Combined with the setting of the rollers, it is convenient for medical staff to quickly and smoothly transport the parturient, reducing the number of transfers of the parturient. At the same time, this design greatly improves the comfort of the parturient and the convenience of operation of the medical staff. The first rotating frame 13 and the fixed rod 12 are both provided with through holes, and the insertion rod is inserted into the through hole where the first rotating frame 13 and the fixed rod 12 overlap, so that the first rotating frame 13 remains stationary relative to the fixed rod 12.

[0021] When the parturient needs to give birth, the medical staff removes the support plate 16, and then adjusts the positions of the two first rotating frames 13 to the positions adjacent to the support plate 16. Figure 2 The state in the middle (this state is a schematic diagram of the three-dimensional structure of the device in the working state), and then the legs of the parturient are fixed on the support frame 15, and the Velcro on the support frame 15 is used to fix the legs of the parturient, so that the parturient is in a lithotomy position (the positions of the two support frames 15 in the figure are only schematic, and the distance between the two can be adjusted according to the size of the bed body 1 to be produced), to assist the parturient in delivery. If the parturient needs to give birth in a side-lying position, the medical staff only needs to install the support plate 16 on the corresponding side to the bed body 1, and then use the support frame 15 on the corresponding side to support the upper legs to assist the parturient in delivery. The support plate 16 can be disassembled in corresponding quantities according to actual needs to adapt to different delivery positions and operation requirements, thereby improving the diversity of the device.

[0022] Reference Figure 1 and Figure 2 As shown, the stabilizing mechanism includes: a swing arm 2, which has two pieces, both of which are rotatably arranged on the bed body 1, and rollers are arranged on the swing arms 2, and the swing arms 2 are used to expand the contact area between the bed body 1 and the ground; a second sliding column 21, which has two pieces, is slidably arranged on adjacent swing arms 2, and the second sliding column 21 is limitedly cooperated with the bed body 1 to lock the relative position of the adjacent swing arms 2 and the bed body 1; a support assembly, which has two pieces, is arranged on adjacent swing arms 2, and the support assembly is used to support adjacent support plates 16.

[0023] In the above scheme, a tension spring in a stretched state is arranged between the second sliding column 21 and the adjacent swing arm 2, and the tension spring is used to increase the contact force between the second sliding column 21 and the bed body 1, so that the swing arm 2 remains stationary relative to the bed body 1, and the roller on the swing arm 2 and the roller on the bed body 1 are located in the same horizontal plane. During the delivery process of the parturient, the medical staff pulls the second sliding column 21 to swing the two swing arms 2 to the adjacent Figure 2 In the state, the subsequent medical staff moves the second sliding column 21 to cooperate with the bed body 1 to lock the swing arm 2 and the bed body 1, thereby preventing the bed body 1 from shaking due to the pain of the parturient turning over during delivery, that is, improving the working stability of the bed body 1, which is convenient for medical staff to deliver the baby smoothly.

[0024] Reference Figure 1 and Figure 2 As shown, the support assembly includes: a support column 3, which is rotatably set on the adjacent swing arm 2, and the support column 3 is in contact with the adjacent support plate 16; a first sliding frame 31, which is slidably set on the adjacent support column 3, and the first sliding frame 31 is limitedly matched with the adjacent swing arm 2 to lock the relative position of the support column 3 and the adjacent swing arm 2.

[0025] In the above scheme, a tension spring in a stretched state is installed between the first sliding frame 31 and the adjacent support column 3. The tension spring maintains the limiting cooperation relationship between the first sliding frame 31 and the swing arm 2. The lower side of the support plate 16 is provided with a groove that is limited and cooperates with the adjacent support column 3, thereby improving the connection stability between the support column 3 and the adjacent support plate 16. The support column 3 supports the adjacent support plate 16, thereby improving the stability of the device under the delivery bed function and improving the supporting strength of the device. Medical staff change the position of the support plate 16 by pulling the first sliding frame 31 to adapt the device to different scenarios.

[0026] Reference Figure 1 and Figure 3 As shown, the limiting mechanism includes: a first ratchet 4, installed on an adjacent fixed rod 12; a second ratchet 41, installed on an adjacent fixed sleeve 11, the second ratchet 41 and the adjacent first ratchet 4 limiting cooperation; a second sliding frame 42, slidably arranged on the adjacent fixed sleeve 11, and fixedly connected to the adjacent second ratchet 41, a tension spring is installed between the second sliding frame 42 and the adjacent fixed sleeve 11.

[0027] In the above scheme, in the initial state, the tension spring connected to the fixed rod 12 is in a stretched state, and the second ratchet 41 only limits the downward movement of the adjacent first ratchet 4, which is convenient for medical staff to lift the fixed rod 12 and quickly adjust the height of the fixed rod 12, so that the support frame 15 can adapt to different parturients and improve the applicability of the device. After the supporting function of the support frame 15 is used up, the medical staff pulls the second sliding frame 42, and the second sliding frame 42 drives the adjacent second ratchet 41 away from the adjacent first ratchet 4, and then resets the first ratchet 4 and the fixed rod 12 and releases the second sliding frame 42.

[0028] Example 2: Based on Example 1, refer to Figure 2-Figure 5 As shown, it also includes a reciprocating mechanism, which has two reciprocating mechanisms, which are respectively arranged on adjacent first rotating frames 13, and the first sliding column 14 is slidingly connected to the adjacent first rotating frame 13 in a limited position. The reciprocating mechanism is used to control the reciprocating movement of the adjacent first sliding column 14, and the reciprocating mechanism includes: a fixed frame 5, which is fixedly connected to the first rotating frame 13, and the fixed frame 5 is fixedly connected to the motor 51; a second rotating frame 52, which is fixedly connected to the output shaft of the motor 51, and the second rotating frame 52 is provided with a slide groove; a sliding rod 53, which is slidably arranged on the slide groove of the second rotating frame 52; a T-shaped rod 54, which is arranged on the adjacent first sliding column 14, and the T-shaped rod 54 is provided with a slide groove, and the sliding rod 53 is located in the slide groove of the T-shaped rod 54 and slides; an adjusting component, which is arranged on the adjacent second rotating frame 52, and the adjusting component is used to adjust the position of the sliding rod 53 on the adjacent second rotating frame 52.

[0029] In the above scheme, the cross-section of the sliding rod 53 in the vertical direction is approximately T-shaped. When the motor 51 works, the output shaft of the motor 51 drives the adjacent second rotating frame 52 and the sliding rod 53 to rotate. The sliding rod 53 rotates and squeezes the slide groove of the adjacent T-shaped rod 54, so that the T-shaped rod 54 drives the adjacent first sliding column 14 and the support frame 15 to move back and forth left and right, wherein the reciprocating movement of the support frame 15 is used to reciprocate the legs of the parturient. At the same time, by changing the rotation frequency of the output shaft on the motor 51, the activity frequency of the parturient's legs is changed, thereby improving the diversity of the device and facilitating the device to drive at different frequencies during different stages of the parturient.

[0030] There are the following benefits for mothers to move their legs during delivery: 1. The movement of the mother's legs can assist the fetus in moving downward into the birth canal, that is, promote the descent of the fetus; 2. The movement of the legs can slightly change the position and shape of the pelvis, expand the pelvis, and help the fetus pass through the birth canal better; 3. The movement of the legs can distract the mother from the pain and relieve the pain; 4. The movement of the legs can promote blood circulation in the lower limbs, reduce swelling and fatigue, and good blood circulation helps to improve the oxygen supply to the fetus and keep the fetus healthy; 5. Exercise can release endorphins, help mothers relax and reduce anxiety; this function can be selectively applied according to the mother's wishes and the actual delivery situation.

[0031] Reference Figure 4 and Figure 5 As shown, the adjustment component includes: a third sliding frame 6, which is slidingly arranged on the adjacent second rotating frame 52 in a limited manner, and the third sliding frame 6 is provided with an oblique groove, and the sliding rod 53 is located in the oblique groove of the adjacent third sliding frame 6 and slides; a fourth sliding frame 61, which is slidingly arranged on the adjacent fixed frame 5 and is rotationally connected to the adjacent third sliding frame 6; a threaded rod 62, which is threadedly arranged on the adjacent fixed frame 5 and is rotationally connected to the adjacent fourth sliding frame 61.

[0032] In the above scheme, the third sliding frame 6 is composed of a disc and two inclined slide rails. Before the motor 51 works to move the legs of the parturient, the medical staff rotates the threaded rod 62. The threaded rod 62 rotates to adjust the positions of the adjacent fourth sliding frame 61 and the adjacent third sliding frame 6. The third sliding frame 6 moves so that the inclined groove on it squeezes the adjacent sliding rod 53. The sliding rod 53 will move along the sliding groove of the adjacent second rotating frame 52, changing the distance between the sliding rod 53 and the center of the adjacent second rotating frame 52, so that when the motor 51 is working normally, the reciprocating movement distance of the support frame 15 is changed, that is, the range of motion of the parturient's legs is changed, and different ranges of motion are selected for parturients in different situations. The rotation adjustment of the threaded rod 62 can also be designed to be driven by electronic components.

[0033] Example 3: Based on Example 2, refer to Figure 6 and Figure 7As shown, it also includes a locking mechanism, which has two, and the two locking mechanisms are respectively arranged on adjacent first sliding columns 14, the first sliding column 14 is connected to the adjacent support frame 15 in a limited sliding manner, and a spring is installed between the first sliding column 14 and the adjacent support frame 15, and the locking mechanism is used to lock the first sliding column 14 and the adjacent support frame 15, and the locking mechanism includes: a first limiting column 7, which is limitedly slidably arranged on the adjacent first sliding column 14, and a spring is installed between the adjacent first sliding column 14, and the support frame 15 is arranged There is a blind hole, and the first sliding column 14 is limitedly matched with the blind hole on the adjacent support frame 15; the fifth sliding frame 71 is slidably set on the adjacent support frame 15, and a spring is installed between the adjacent support frame 15, and the fifth sliding frame 71 is provided with an inclined surface, and the inclined surface of the fifth sliding frame 71 is squeezed and matched with the adjacent first limiting column 7; the locking assembly is arranged on the first sliding column 14, and the T-shaped rod 54 is slidably connected with the adjacent first sliding column 14, and the locking assembly is used to lock the relative position of the T-shaped rod 54 and the adjacent first sliding column 14.

[0034] In the above scheme, in the initial state, the spring between the support frame 15 and the adjacent first sliding column 14, the spring between the first limiting column 7 and the adjacent first sliding column 14, and the spring between the fifth sliding frame 71 and the adjacent support frame 15 are all in a compressed state, and the first limiting column 7 is inserted into the blind hole of the adjacent support frame 15. If the parturient tightens her legs due to pain during delivery, her legs will squeeze the fifth sliding frame 71 to move, and the fifth sliding frame 71 moves so that its upper inclined surface squeezes the adjacent first limiting column 7, and the first limiting column 7 is pressed and moves gradually from the blind hole of the adjacent support frame 15. After the first limiting column 7 is pulled out from the inside, and the cooperation with the blind hole on the adjacent support frame 15 is released, the legs of the parturient squeeze the two support frames 15 together, reducing the opening angle between the legs of the parturient and reducing the discomfort of the parturient. After the tingling sensation of the parturient subsides, the tightening force of the legs of the parturient becomes smaller, so that the fifth sliding frame 71 moves in the opposite direction and resets under the elastic force of the connected spring, and the support frame 15 moves in the opposite direction and resets at the same time. After the blind hole on the support frame 15 is facing the adjacent first limiting column 7, the first limiting column 7 is reinserted into the blind hole of the adjacent support frame 15, and the above operation is repeated subsequently.

[0035] Reference Figure 6 , Figure 8 and Fig. 9As shown, the locking assembly includes: a second limiting column 8, which is slidably set on the adjacent first sliding column 14, and a spring is installed between the adjacent first sliding column 14, a T-shaped rod 54 is provided with a blind hole, the second limiting column 8 is limitedly matched with the blind hole of the adjacent T-shaped rod 54, the first sliding column 14 is provided with a plurality of air guide holes 81, the first sliding column 14 is provided with two sliding chambers, the two sliding chambers are respectively used for the sliding of the adjacent second limiting column 8 and the sliding of the adjacent support frame 15, and the plurality of air guide holes 81 are used to connect the two adjacent sliding chambers; a one-way valve is installed in half of the air guide holes 81 on the first sliding column 14 to hinder the flow of the flowing medium.

[0036] In the above installation, in the initial state, the spring connected to the second limit column 8 is in a compressed state, and the second limit column 8 is inserted into the blind hole of the adjacent T-shaped rod 54. A ball is provided at the upper end of the second limit column 8 to reduce the friction between the second limit column 8 and the adjacent first sliding column 14. Two air guide holes 81 are provided, and a one-way valve is installed in one of the air guide holes 81. The number of these air guide holes 81 is schematically shown in the figure, and the actual number can be set to a specified number according to the size of the actual parts.

[0037] During the movement of the support frame 15 relative to the adjacent first sliding column 14, the support frame 15 draws the gas in the sliding chamber of the adjacent second limiting column 8 into its sliding chamber through the two adjacent air guide holes 81, so that the gas pressure in the sliding chamber of the second limiting column 8 gradually decreases to form a negative pressure. Under the action of the negative pressure, the second limiting column 8 moves and is gradually pulled out of the blind hole of the adjacent T-shaped rod 54, disconnecting the power transmission between the T-shaped rod 54 and the adjacent first sliding column 14, so that the legs of the parturient remain still and avoid secondary stimulation to the parturient. After the tingling sensation of the parturient subsides, as the T-shaped rod 54 reciprocates, when the T-shaped rod 54 moves to the point where the blind hole on it is facing the adjacent second limiting column 8, the second limiting column 8 is reinserted into it to restore the initial state, and the above operation is subsequently repeated.

[0038] Reference Figure 8 As shown, the locking assembly also includes: a sliding plate 9, which is slidably set on the adjacent first sliding column 14, the sliding plate 9 is provided with a wavy surface, the first rotating frame 13 is provided with a wavy surface, the wavy surface of the sliding plate 9 is limitedly matched with the wavy surface of the adjacent first rotating frame 13; an elastic telescopic column 91, which is fixedly connected to the adjacent second limiting column 8, and penetrates the adjacent first sliding column 14 and is fixedly connected to the adjacent sliding plate 9.

[0039] In the above scheme, the elastic telescopic column 91 is composed of two cylindrical shells and a spring, and in the initial state, the wavy surface on the sliding plate 9 does not cooperate with the wavy surface on the adjacent first rotating frame 13, so that the first sliding column 14 can move back and forth in the adjacent first rotating frame 13 to adapt to the reciprocating movement of the legs of the parturient. When the parturient is severely stimulated and tightens her legs, the above operation is repeated, and the power transmission between the T-bar 54 and the adjacent first sliding column 14 is disconnected, wherein the second limiting column 8 moves through the adjacent elastic telescopic column 91 to drive the adjacent sliding plate 9 to move, and the sliding plate 9 moves so that its upper wavy surface is tightly fitted with the wavy surface of the adjacent first rotating frame 13 and the two are relatively fixed. At this time, the first sliding column 14 is fixed relative to the adjacent first rotating frame 13 to avoid the complete merging of the legs of the parturient. After the tingling sensation of the parturient is reduced, the wavy surface on the sliding plate 9 is released from the cooperation with the wavy surface on the adjacent first rotating frame 13, and then the initial state is restored to work.
