Description

Technical Field

[0001] The present invention relates to the technical field of delivery beds, and more particularly to a delivery bed for midwifery. Background Art

[0002] The delivery bed is a support and midwifery tool used to assist pregnant women in giving birth to newborns. It helps technicians to adjust the posture of the delivery bed according to the different pregnancy conditions of pregnant women, thereby ensuring the safety of pregnant women's force production. The delivery bed is evaluated based on its use after the pregnant women give birth, and the delivery beds that pass the evaluation are mass-produced and put on the market for sale and use in obstetrics and gynecology hospitals.

[0003] In the existing process of giving birth while a pregnant woman lies on a hand-cranked delivery bed, the pregnant woman is usually first made to sit on the edge of the delivery bed, and then the pregnant woman's legs are raised and placed flat on the bed board, and then the medical staff manually cranks the delivery bed to drive the backrest to lift up, so that the bed backrest can be close to the pregnant woman's back to drive the pregnant woman to slowly stand up, and the pregnant woman can start to pull the handle to exert force to give birth according to the support of the delivery bed.

[0004] However, in this method, since the handle pulled by the pregnant woman is in a fixed state, the pregnant woman's back will be pulled up after applying force, so the pregnant woman's back and the bed backrest will still be separated. As a result, the pregnant woman has to apply greater force to maintain her balance while applying force for delivery, causing the pregnant woman to consume too much force, resulting in uneven force application, mental fatigue, and uterine contractions and dystocia, which reduces the efficiency of the delivery bed in assisting delivery. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) This scheme provides a stretching and clamping component. When the pregnant woman pulls the hand lever to the left, the bed backrest can be indirectly driven to lift and adjust the angle. Therefore, after the bed backrest is in close contact with the pregnant woman's back, an unobstructed integrated force production state can be formed. The pregnant woman can drive the bed backrest to fit the pregnant woman's back by pulling the hand lever by herself, so as to avoid the pregnant woman lying on the delivery bed to give birth to the fetus. Because the bed backrest is not an angle backrest formed after the pregnant woman adjusts it, when the pregnant woman pulls the hand lever in a fixed state, the pregnant woman's back and the adjusted and fixed bed backrest will still be separated. As a result, after the pregnant woman is pulled up, she needs to apply more force to maintain her body balance, resulting in uneven force application during delivery, increased risk of delivery, dystocia, cervical edema, etc., to improve the comfort of the pregnant woman's delivery force, enhance the effect of multi-angle bending of the bed backrest, and ensure the normal use of the pregnant woman to deliver the fetus.

[0019] (2) This scheme provides a shock-absorbing component, which can indirectly cause arc rod one to compress spring three to contract inwardly towards arc rod two when the bed back continues to turn to the right, so that arc rod one can remove the shaking force generated when the bed back is lifted and turned, thereby enhancing the safety of pregnant women during childbirth and avoiding the vibration and impact force generated by the bed back during the lifting process, which may make some large pregnant women uncomfortable during childbirth and reduce the efficiency of stable childbirth for pregnant women. It can also cause vibration wear and looseness of various parts of the delivery bed, increasing the possibility of unsafe childbirth for large pregnant women, improving the efficiency of the bed back in providing stable childbirth for large pregnant women, enhancing the strength of the bed back and the delivery bed to be lifted without vibration, and ensuring the normal use of the delivery bed.

[0020] (3) This solution provides a push-back assembly, which can drive the top back cushion to push the back tightly against the pregnant woman's back under the action of the up and down movement force of the top back cushion, so as to avoid the bed back being lifted at too high a speed and with too much impact force, which may cause the pregnant woman's back to contact the bed back and cause impact tension, physical discomfort, excessive frightening to the pregnant woman, and dystocia of the fetus. This improves the effectiveness of safe delivery without injury to pregnant women, enhances the effect of the delivery bed in assisting delivery without interference, increases the comfort of the pregnant woman's back force delivery, and ensures the normal use of the bed for healthy delivery.

[0038] The telescopic swing rod 26 is composed of a movable rod and a telescopic rod, and the telescopic rod is rotatably connected to the sliding column 24, and the movable rod is rotatably connected to the swing rod 27. When the sliding column 24 pushes the telescopic rod to rotate and move, the movable rod can pull the swing rod 27 to form a mutual transmission effect.

[0039] The bottom of the bed board 12 is fixedly connected to the delivery bed 1, the cylinder 1 212 and the cylinder 2 213 are both fixedly connected to the delivery bed 1, the top of the concave rod 21 is fixedly connected with a hand rod 22, and two hand rods 22 are provided, and the two hand rods 22 are symmetrically distributed, and the two sides of the bed board 12 are fixedly connected with a slide rail 1 23, and the slider on the top side of the concave rod 21 is in a sliding card connection with the slide rail 1 23.

[0040] A spring 25 is fixedly connected to the left side of the concave rod 21 . Two springs 25 are provided. The two springs 25 are symmetrically distributed. The left end of the spring 25 is fixedly connected to the inner wall of the delivery bed 1 .

[0041] A slot rod 211 is fixedly connected to the inner wall of the delivery bed 1, and a bevel telescopic block 29 is slidably engaged in the slot wall of the slot rod 211. Two bevel telescopic blocks 29 are provided, and the two bevel telescopic blocks 29 are symmetrically distributed.

[0042] The main body of the slot rod 211 is a rod, and slots are evenly opened on the side of the rod. The slots can provide adaptive adjustment capabilities for the two inclined surfaces of the bevel telescopic block 29 according to the plug-in and telescopic movement of the bevel telescopic block 29, thereby reducing the degree of wear of the slots and the bevel telescopic block 29.

[0043] A spring 210 is fixedly connected to the front side of the bevel telescopic block 29. Two springs 210 are provided. The two springs 210 are symmetrically distributed on the inner wall of the concave rod 21. One end of the spring 210 is fixedly connected to the concave rod 21. The front side of the bevel telescopic block 29 penetrates and is slidably connected to the concave rod 21.

[0044] With regard to the existing delivery bed 1 in the prior art, when adjusting the comfortable angle of the pregnant woman's back bend, it is necessary to use external force to adjust it, and the pregnant woman herself cannot pull the hand pull rod 22 to synchronously adjust the lifting angle of the bed backrest 11 to adjust the comfort. Therefore, when the pregnant woman pulls the hand pull rod 22 in a fixed state, the pregnant woman's back will be pulled up after applying force, so that the pregnant woman's back and the bed backrest 11 will still be separated, causing the pregnant woman to consume too much force when applying force for delivery, causing the pregnant woman to feel uncomfortable after applying force for a long time, and the pregnant woman will be listless and have uterine contractions and dystocia. The present application provides a stretching and fixing component 2. When in use, the pregnant woman is first helped to sit on the bed board 12, and the pregnant woman's back is facing the bed board 12. The pregnant woman is placed on the top surface of the bed backrest 11. If her feet are off the ground and she is half lying on the bed backrest 11, she can be told to hold the hand pull rod 22. At this time, the pregnant woman can pull the hand pull rod 22 to move to the left, driving the fixedly connected concave rod 21 to slide to the left, thereby causing the concave rod 21 to drive the sliding column 24 to move to the left, so that the sliding column 24 squeezes the spring 1 25 to contract to the left, and causes the sliding column 24 to push the right end of the telescopic swing rod 26 to move to the left. At this time, the telescopic swing rod 26 will rotate around the axis of the cylinder 1 212 as the center, so that the telescopic swing rod 26 can rotate clockwise. At the same time, when the right end of the telescopic swing rod 26 rotates, the right end of the telescopic swing rod 26 can also gradually contract inward. When the telescopic swing rod 26 is further rotated, the right end of the telescopic swing rod 26 contracts inward to reduce the problem of mechanical interference, so that the left end of the telescopic swing rod 26 pulls the swing rod 1 27 to rotate clockwise, and the swing rod 1 27 pulls the swing rod 2 28 to rotate clockwise. At this time, the swing rod 2 28 can rotate around the axis of the cylinder 2 213, so that the swing rod 2 28 can rotate clockwise, and the top of the swing rod 2 28 can push the bed back 11 to rotate around the axis of the left end of the bed board 12. At this time, the bed back 11 can be lifted and rotated clockwise. After the bed back 11 contacts the back of the pregnant woman, the bed back 11 and the pregnant woman can form an unobstructed integration. The pregnant woman can synchronously drive the bed backrest 11 to fit the pregnant woman's back by pulling the hand pull rod 22, ensuring that the bed backrest 11 will not separate from the pregnant woman's back when the pregnant woman pulls the hand pull rod 22 hard during childbirth. From the perspective of gynecological childbirth, it can reduce the problem of uneven force application during childbirth and increase the comfort of the pregnant woman. In addition, the sliding column 24 can squeeze the spring 25 to the left under the action of contraction and accumulation of force, which will gradually increase the reverse thrust formed by the spring 25, causing the speed of the bed backrest 11 turning and pushing the back to slow down, thereby increasing the pregnant woman's ability to clearly perceive the push back, relieving the tension of the pregnant woman during childbirth, and ensuring the normal use of the safe childbirth of the pregnant woman.

[0045] After the pregnant woman gives birth, she will be powerless and her body will lean back. At this time, the bed backrest 11 can squeeze the swing rod 28 to rotate counterclockwise, and indirectly push the bottom of the telescopic swing rod 26 to rotate counterclockwise, and at the same time make the telescopic swing rod 26 push the sliding column 24 to move right. At this time, the sliding column 24 can push the concave rod 21 to move right, and make the concave rod 21 can drive the two beveled telescopic blocks 29 to move right. Therefore, after the right bevel of the beveled telescopic block 29 contacts the left side of the slot of the slot rod 211, under the action of the rightward movement force of the concave rod 21, the bevel end of the beveled telescopic block 29 will squeeze the spring 210 to shrink into the concave rod 21. When the beveled telescopic block 29 shrinks to the inside of the slot rod 211, the concave rod 21 can continue to move to the right. When the left wall of the other slot is flush with the left wall of the other slot, under the action of the continuous rightward movement force of the concave rod 21, the bevel telescopic block 29 can gradually contact with the other slot of the slot rod 211 and be in a semi-suspended state. At this time, the spring 210 in the squeeze storage can form a reverse thrust to push the bevel telescopic block 29 to extend backward, so that the bevel telescopic block 29 can gradually extend into the other slot of the slot rod 211. At this time, the bevel telescopic block 29 that is gradually telescoped to the right can gradually slow down the speed of the bed backrest 11 descending, reduce the risk of the bed backrest 11 suddenly descending when the pregnant woman leans back in a powerless state, maintain the safety of the pregnant woman leaning back in a powerless state after delivery, enhance the effect of the bed backrest 11 buffering the descent, improve the safety of the pregnant woman during delivery, increase the probability of safe and normal delivery, and ensure the normal use of the delivery bed 1 and the bed backrest 11 for assisting delivery.

[0046] The present invention provides a stretching and clamping component 2, and when the pregnant woman pulls the hand pull rod 22 to the left, the bed backrest 11 can be indirectly driven to lift and adjust the angle. Therefore, after the bed backrest 11 is in close contact with the pregnant woman's back, an unobstructed integrated force-applying production state can be formed. The pregnant woman can synchronously drive the bed backrest 11 to fit the pregnant woman's back by pulling the hand pull rod 22 by herself, so as to avoid the pregnant woman lying on the delivery bed 1 to deliver the fetus. Because the bed backrest 11 is an angle backrest formed only after adjustment by the non-pregnant woman, when the pregnant woman pulls the hand pull rod 22 in the fixed state, the pregnant woman's back and the adjusted and fixed bed backrest 11 will still be separated, so that after the pregnant woman is pulled up, she needs to apply more force to maintain her body balance, resulting in uneven force application during delivery, increased risk of delivery, dystocia, cervical edema, etc., improve the comfort of pregnant women in delivery, enhance the effect of multi-angle bending of the bed backrest 11, and ensure the normal use of pregnant women in delivery.

[0047] like Figures 5 to 7 As shown, the outer surface of the bed backrest 11 is symmetrically provided with shock absorbing components 3, and the shock absorbing components 3 are provided with two groups;

[0048] The shock absorbing assembly 3 includes an arc-shaped rod 31 , and the arc-shaped rod 31 is fixedly connected to the front side of the bed backrest 11 .

[0049] The right end of the arc rod 1 31 passes through and is slidably connected to the left end of the arc rod 2 32. The right end of the arc rod 1 31 is fixedly connected to a spring 33. The right end of the spring 33 is fixedly connected to the inner bottom wall of the arc rod 2 32. The rear side of the arc rod 2 32 is fixedly connected to the bed board 12.

[0050] By setting the shock absorbing component 3, when in use, the bed backrest 11 can be lifted and the clockwise rotation force is applied, so that the bed backrest 11 drives the arc rod 1 31 to rotate clockwise, so that the arc rod 1 31 squeezes the spring 33 to shrink into the arc rod 2 32, so that when the arc rod 1 31 squeezes the spring 33 to shrink and accumulate force, the spring 33 can form a reverse thrust, driving the left end of the spring 33 to push the arc rod 1 31, so that the slight shaking of the bed backrest 11 during the corner turning process can be eliminated, reducing the interference of the shaking of the bed backrest 11 on the delivery of pregnant women, improving the efficiency of the stable delivery of pregnant women, enhancing the use effect of the bed backrest 11, and ensuring that pregnant women can use it normally during delivery without worries.

[0051] It should be noted that after the bed backrest 11 is lifted, the elastic push-pull force formed by the arc rod 1 31 and the spring 3 33 can not only reduce the shaking generated during the lifting process of the bed backrest 11, but also at the moment when some large pregnant women apply force, through the action of the large pregnant women applying force on the backrest, the bed backrest 11 is driven to press the arc rod 1 31 and the spring 3 33, so that the spring 3 33 squeezed to a certain position forms a shock force opposite to the bed backrest 11, thereby removing the excess force applied by large pregnant women during delivery, reducing the impact force, enhancing the comfort of large pregnant women during delivery, and ensuring the normal and safe delivery of large pregnant women.

[0052] By setting up the shock absorbing component 3, the present scheme can indirectly make the arc rod 1 31 press the spring 3 33 to shrink into the arc rod 2 32 when the bed back 11 continues to turn to the right, so that the arc rod 1 31 can remove the shaking force generated when the bed back 11 is lifted and turned, thereby enhancing the safety of pregnant women in delivery, avoiding the vibration and impact force generated by the bed back 11 in the process of lifting, which may make some large pregnant women uncomfortable during delivery and reduce the efficiency of stable delivery of pregnant women, and also cause vibration wear and looseness of various parts of the delivery bed, thereby increasing the possibility of unsafe delivery for large pregnant women, improving the efficiency of the bed back 11 in providing stable delivery for large pregnant women, enhancing the force of the bed back 11 and the delivery bed 1 to lift without vibration, and ensuring the normal use of the delivery bed 1.

[0053] like Figure 8 and Fig. 9As shown, a back-pushing assembly 4 is provided through the top of the bed backrest 11 and the top of the mattress 13;

[0054] The push back assembly 4 includes a support plate 46, which passes through and is fixedly connected to the inner wall of the bed backrest 11. Two sides of the support plate 46 are fixedly connected with two bidirectional telescopic rods 42. The two bidirectional telescopic rods 42 are symmetrically distributed about the support plate 46.

[0055] The front sides of the two-way telescopic rods 42 are fixedly connected with column blocks 48, and the front sides of the column blocks 48 are fixedly connected to the inner walls of the bed backrest 11. The outer surfaces of the column blocks 48 are rotatably connected with diamond-shaped support frames 41, and the outer surfaces of the diamond-shaped support frames 41 penetrate and are slidably connected with the bed backrest 11 and the mattress 13. The top of the diamond-shaped support frame 41 is rotatably connected with a top back cushion 44, and the bottom of the diamond-shaped support frame 41 is rotatably connected with a movable plate 43, and the movable plate 43 is located between the two telescopic swing rods 26. The top of the movable plate 43 is fixedly connected to the two two-way telescopic rods 42, and the tops of the two two-way telescopic rods 42 are fixedly connected to the top back cushion 44.

[0056] The top of the movable plate 43 is fixedly connected to a spring four 45, the top of the spring four 45 is fixedly connected to the support plate 46, the bottom of the top back pad 44 is fixedly connected to a deformable elastic leather cover 47, and the bottom of the deformable elastic leather cover 47 is fixedly connected to the mattress 13.

[0057] By setting up the push-back assembly 4, when working, the pregnant woman can indirectly control the bed backrest 11 to turn right by pulling the hand pull rod 22, so that the bed backrest 11 can gradually contact with the pregnant woman's back, and at the same time, the bed backrest 11 drives the push-back assembly 4 to move toward the back of the pregnant woman. When the top back cushion 44 moves to the right until it is in contact with the pregnant woman's back, under the action of the continuous right-turning force of the bed backrest 11, the pregnant woman can squeeze the top back cushion 44 to move downward, and the top back cushion 44 presses the top of the diamond support frame 41 and the top of the two-way telescopic rod 42 to move downward, so that the bottom of the diamond support frame 41 pulls the movable plate 43 to move upward, and at the same time, the movable plate 43 squeezes the spring four 45 to shrink upward, so that the movable plate 43 pushes the bottom of the two-way telescopic rod 42 The top back pad 44 contracts upward, and when the top surface of the top back pad 44 contracts downward to be flush with the top surface of the bed back 11, the bed back 11 can be completely fitted with the back of the pregnant woman. Therefore, by pre-fitting the top back pad 44 with the back of the pregnant woman, the pregnant woman is prepared when fitting with the bed back 11. The squeezing and conducting force of the top back pad 44 increases the reaction time and psychological preparation of the pregnant woman to the pre-fitting of the bed back 11, reduces the phenomenon of fright and panic of the pregnant woman after the bed back 11 suddenly fits with the back of the pregnant woman, avoids the problem of dystocia and miscarriage caused by the sudden fit of the bed back 11, improves the accuracy of the efficient delivery of the pregnant woman, enhances the strength of the bed back 11 to assist delivery without damage, and ensures the normal delivery of the pregnant woman.

[0058] On the other hand, through the back-pushing operation of the top back pad 44, when the pregnant woman moves her back, the spring four 45 in the squeezed state can form a reverse thrust, pushing the movable plate 43 to move downward, and driving the movable plate 43 to pull the bottom of the two-way telescopic rod 42 and the bottom of the diamond-shaped support frame 41 to move downward, so that the top of the diamond-shaped support frame 41 can push the top back pad 44 to move upward, so that the top back pad 44 can reversely push the pregnant woman's back, making the pregnant woman's waist more comfortable, avoiding the pregnant woman from maintaining a backrest posture for a long time, causing the pregnant woman to have backache and fatigue, thereby improving the convenience of pregnant women to exert force during delivery.

[0059] It should be noted that the up and down movement of the diamond-shaped support frame 41 can be guided by the two-way telescopic rod 42 to fix the up and down movement trajectory, so that the diamond-shaped support frame 41 can smoothly adjust the movement distance of the top back pad 44 and the movable plate 43;

[0060] The deformable elastic leather cover 47 is used to shield and protect the diamond-shaped support frame 41 and the two-way telescopic rod 42, and is stretched and deformed in coordination with the movement of the top back pad 44.
