Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, specifically an adjustable medical bed for patients in traditional Chinese medicine obstetrics and gynecology. Background Technology

[0002] In the clinical diagnosis and treatment of obstetrics and gynecology in traditional Chinese medicine, patients often need to undergo a variety of body position changes, including supine position for pregnancy preservation and rest, semi-recumbent position for postpartum recovery, lithotomy position for gynecological examination and perineal operation, and prone position for moxibustion and massage treatment of the lumbosacral region. The obstetrics and gynecology patient group has its own special characteristics. During pregnancy, the abdomen is bulging and pressure should be avoided. Postpartum patients have perineal wounds and need to reduce traction. Patients who are bedridden for a long time to preserve pregnancy face the risk of deep vein thrombosis in the lower extremities and pressure sores. The existing adjustable medical beds for obstetric and gynecological patients in traditional Chinese medicine often use independent electric push rods to drive the backrest and legrests. When the backrest is raised, the patient's torso slides down the bed surface due to gravity, causing the abdominal skin and subcutaneous tissue to be pulled by shear force. For obstetric and gynecological patients who are pregnant or have undergone cesarean section, this shear force can directly pull on the abdominal wall incision or increase uterine pressure, which is not conducive to wound healing and fetal stability. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable medical bed for patients in traditional Chinese medicine obstetrics and gynecology. When the first rotating shaft rotates, it drives the gears at both ends to rotate synchronously. The gears mesh with the rack and drive the rack to move horizontally towards the tail of the bed. The rack pushes the seat plate and its internal telescopic layer to slide towards the tail of the bed. When the backrest is raised, the seat plate moves backward synchronously, which effectively increases the sacral support space and avoids abdominal pressure caused by the patient sliding down due to inertia. It is suitable for patients with threatened miscarriage or postpartum wound recovery period.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an adjustable medical bed for patients in traditional Chinese medicine obstetrics and gynecology, comprising a bed body, an adjustment mechanism installed on the bed body, a support installed at the bottom of the bed body, and an auxiliary mechanism installed on the bed body; The adjustment mechanism includes a first electric push rod mounted on a bracket. A back plate is movably mounted on the output end of the first electric push rod. A first rotating shaft is rotatably connected to one end of the back plate. The first rotating shaft rotates inside the bed. Gears are mounted on both ends of the first rotating shaft. A rack meshes with one side of the gear. A seat plate is connected to one end of the rack. A telescopic layer is movably mounted inside the seat plate. A movable block is movably installed inside the back panel. An elastic rope is installed at one end of the movable block. One end of the elastic rope passes through the back panel and connects to the bed frame. A compression rod is installed on one side of the seat plate. The auxiliary mechanism includes a leg plate that is rotatably connected to the bed. A second electric push rod is installed at the bottom of the leg plate. The output end of the second electric push rod is connected to two sets of lifting seats. An inclined block is installed at the bottom of the leg plate. One end of the pressing rod is movably connected to the inclined block.

[0005] Preferably, the bottom of the bracket is equipped with multiple sets of omnidirectional wheels, and the output end of the first electric push rod is connected to a flexible joint, one end of which is movably connected to the back plate.

[0006] Preferably, both sets of gears and racks move inside the bed, and an elastic rod is installed inside the seat plate, with one end of the elastic rod connected to the telescopic layer.

[0007] Preferably, each end of the movable block is provided with a connecting plate, and each of the two sets of connecting plates is equipped with a spring at its bottom. One end of each of the two sets of springs is connected to the back plate, and one end of each of the two sets of connecting plates is connected to an elastic rope. Two sets of connecting parts are installed at the bottom of the bed, and one end of each of the two sets of elastic ropes is connected to the two sets of connecting parts.

[0008] Preferably, guardrails are installed on both sides of the bed, and two sets of electric telescopic rods are installed inside the bed, with the output ends of the two sets of electric telescopic rods respectively connected to the guardrails.

[0009] Preferably, limiting blocks are installed on both sides of the seat plate, and the bed body has a groove with a size that matches the limiting blocks.

[0010] Preferably, one end of the extrusion rod is provided with an extrusion head, and one end of the extrusion head is movably connected to the inclined block.

[0011] Preferably, a mounting base is provided at the bottom of the leg plate, the second electric push rod is mounted on the mounting base, the output end of the second electric push rod is connected to a movable plate, and two sets of connecting rods are installed on the movable plate, with one end of each set of connecting rods connected to a lifting seat.

[0012] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes the rotation of the first rotating shaft to drive the gears at both ends to rotate synchronously. The gears mesh with the rack and drive the rack to move horizontally towards the end of the bed. The rack pushes the seat plate, along with its internal telescopic layer, to slide towards the end of the bed. When the backrest is raised, the seat plate moves backward synchronously, effectively increasing the sacral support space and avoiding abdominal pressure caused by the patient sliding down due to inertia. It is suitable for patients with threatened miscarriage or postpartum wound recovery period.

[0013] This invention utilizes a first electric push rod to lift the upper part of the backrest, gradually tightening the elastic rope and generating a downward pulling force on the movable block. The movable block overcomes the supporting force of the spring, slides backward and downward along the groove of the backrest, and slightly tilts upward. The movement of the movable block backward and downward transfers the stress point of the patient's lumbosacral region from the hard bed board to the flexible elastic support, avoiding pressure on the sacrum and coccyx when sitting up. It is suitable for patients who have undergone episiotomy after childbirth or are at risk of pressure sores in the sacrum and coccyx. At the same time, the downward movement of the movable block conforms to the physiological curve of the pelvis naturally tilting backward when the human body is in a sitting position, keeping the lumbar spine in a neutral position and avoiding excessive tension in the abdominal muscles. This is especially important for patients with threatened miscarriage who are trying to maintain their pregnancy.

[0014] As the seat slides towards the foot of the bed, the invention causes the compression rod on its side to move synchronously. The compression head at the front end of the compression rod gradually contacts and compresses the inclined block at the bottom of the leg board. After the inclined block is compressed, it causes the leg board to tilt upward around the rotation connection point between itself and the bed. The leg board rises, raising the patient's lower limbs as a whole, with the feet positioned above the level of the heart. Gravity assists in the return of venous blood to the heart, reducing the risk of deep vein thrombosis in the lower limbs. At the same time, the popliteal fossa is flexibly supported by the lifting seat, avoiding compression of the popliteal artery and ensuring that the blood supply to the distal lower leg is not affected.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] See Figures 1 to 7 As shown, the present invention provides an adjustable medical bed for patients in traditional Chinese medicine obstetrics and gynecology, including a bed body 1, an adjustment mechanism 2 installed on the bed body 1, a support 11 installed at the bottom of the bed body 1, and an auxiliary mechanism 3 installed on the bed body 1. The adjustment mechanism 2 includes a first electric push rod 21 mounted on the bracket 11. A back plate 22 is movably mounted on the output end of the first electric push rod 21. A first rotating shaft 24 is rotatably connected to one end of the back plate 22. The first rotating shaft 24 rotates inside the bed 1. Gears 25 are mounted on both ends of the first rotating shaft 24. A rack 26 meshes with one side of the gear 25. One end of the rack 26 is connected to a seat plate 212. A telescopic layer 213 is movably mounted inside the seat plate 212. A movable block 29 is movably installed inside the back panel 22. An elastic rope 28 is installed at one end of the movable block 29. One end of the elastic rope 28 passes through the back panel 22 and is connected to the bed frame 1. A compression rod 218 is installed on one side of the seat plate 212. The auxiliary mechanism 3 includes a leg plate 31 that is rotatably connected to the bed 1. A second electric push rod 34 is installed at the bottom of the leg plate 31. Two sets of lifting seats 32 are connected to the output end of the second electric push rod 34. An inclined block 37 is installed at the bottom of the leg plate 31. One end of the pressing rod 218 is movably connected to the inclined block 37.

[0019] When in use, the first electric push rod 21 is activated, and its output end pushes the back plate 22 to rotate upward around the first rotating shaft 24 through the flexible joint 23. When the first rotating shaft 24 rotates, it drives the gears 25 at both ends to rotate synchronously. The gears 25 mesh with the rack 26 and drive the rack 26 to move horizontally towards the end of the bed. The rack 26 pushes the seat plate 212 together with the telescopic layer 213 inside it to slide towards the end of the bed. At the same time, the telescopic layer 213 can always keep in contact with the leg plate 31 under the action of the elastic rod 217. The limiting blocks 221 on both sides of the seat plate 212 slide in the groove inside the bed body 1 to ensure that the seat plate 212 moves in a straight line without deviation. When the back plate 22 is raised, the seat plate 212 moves backward synchronously, which effectively increases the sacral support space and avoids the abdominal pressure caused by the patient sliding down due to inertia. It is suitable for patients with threatened miscarriage or postpartum wound recovery period. When the first electric push rod 21 pushes the upper part of the back plate 22 to rise, the elastic rope 28 is gradually tightened, generating a downward pulling force on the movable block 29. The movable block 29 overcomes the supporting force of the spring 211, slides backward and downward along the groove of the back plate 22 and tilts slightly. The movable block 29 moves backward and downward, so that the stress point of the patient's lumbosacral region is transferred from the hard bed board to the flexible elastic support, avoiding pressure on the sacrum and coccyx when sitting up. It is suitable for patients who have undergone episiotomy after childbirth or have a risk of pressure sores in the sacrum and coccyx. At the same time, the sinking of the movable block 29 conforms to the physiological curve of the pelvis naturally tilting backward when the human body is in a sitting position, keeping the lumbar spine in a neutral position and avoiding excessive tension in the abdominal muscles. This is especially important for patients with threatened miscarriage who are trying to save their pregnancy. When the seat 212 slides toward the foot of the bed, it drives the compression rod 218 on its side to move synchronously. The compression head 220 at the front end of the compression rod 218 gradually contacts and compresses the inclined block 37 at the bottom of the leg board 31. After the inclined block 37 is compressed, it causes the leg board 31 to tilt upward around its rotation connection point with the bed 1. The leg board 31 rises, raising the patient's lower limbs as a whole, with the foot position higher than the level of the heart. Gravity assists in the return of venous blood to the heart, reducing the risk of deep vein thrombosis in the lower limbs. At the same time, the popliteal fossa is flexibly supported by the lifting seat 32, avoiding compression of the popliteal artery and ensuring that the blood supply to the distal lower leg is not affected.

[0020] The second electric push rod 34 is activated, which pushes the two sets of lifting seats 32 upward through the movable plate 35 and the two sets of connecting rods 36 to lift the patient's lower leg. This achieves a secondary lift after the basic linkage of the leg board 31, which raises the lower limb as a whole to promote venous return. At the same time, the perineal exposed area increases, and doctors can complete vaginal speculum examinations, cervical smears and other operations without repeatedly lifting the patient's lower limbs. During perineal irrigation, nursing staff can complete the irrigation operation with one hand, and the cleaning solution can flow down the buttock crease naturally to avoid contaminating the bed surface.

[0021] In an optional embodiment, multiple sets of casters 12 are installed at the bottom of the bracket 11, and a flexible joint 23 is connected to the output end of the first electric push rod 21. One end of the flexible joint 23 is movably connected to the back plate 22.

[0022] It should be noted that the multiple sets of casters 12 installed at the bottom of the bracket 11 are equipped with brake locking devices. After the bed 1 is positioned in the treatment or nursing position, stepping on the brake can fix the bed 1 in place. The flexible joint 23 connected to the output end of the first electric push rod 21 is a rubber universal joint structure, which allows the back plate 22 to produce an angular sway between itself and the output end of the first electric push rod 21 during the rotation of the first rotating shaft 24, thus avoiding the push rod bending or the back plate 22 getting stuck due to rigid connection.

[0023] In an optional embodiment, both sets of gears 25 and rack 26 are movable inside the bed 1, and an elastic rod 217 is installed inside the seat plate 212, with one end of the elastic rod 217 connected to the telescopic layer 213.

[0024] It should be noted that both sets of gears 25 and racks 26 are set in the closed slide groove inside the bed body 1. The rack 26 moves back and forth in a straight line along the slide groove. When the seat plate 212 slides towards the foot of the bed, the elastic rod 217 pushes the telescopic layer 213 to always fit the patient's buttocks. When the seat plate 212 returns to its original position, the elastic rod 217 assists the telescopic layer 213 to retract to the initial position.

[0025] In an optional embodiment, the movable block 29 is provided with connecting plates 210 at both ends, and springs 211 are installed at the bottom of the two sets of connecting plates 210. One end of the two sets of springs 211 is connected to the back plate 22, and one end of the two sets of connecting plates 210 is connected to the elastic rope 28. Two sets of connectors 27 are installed at the bottom of the bed body 1, and one end of the two sets of elastic ropes 28 is connected to the two sets of connectors 27.

[0026] It should be noted that the elastic rope 28 is a highly elastic rubber rope. One end of it is fixed to the connecting plates 210 at both ends of the movable block 29, and the other end passes through the guide hole at the bottom of the back panel 22 and is fixed to the connector 27 at the bottom of the bed frame 1. When the back panel 22 is flipped from a supine to a sitting position, the elastic rope 28 is gradually stretched, which drives the connecting plate 210 to transmit to the movable block 29, pulling the movable block 29 to slide along the slide groove towards the head of the bed.

[0027] In an optional embodiment, guardrails 215 are installed on both sides of the bed 1, and two sets of electric telescopic rods 216 are installed inside the bed 1, with the output ends of the two sets of electric telescopic rods 216 connected to the guardrails 215 respectively.

[0028] It should be noted that the height of the guardrail 215 can be adjusted by two sets of electric telescopic rods 216, making it convenient for patients of different heights to use.

[0029] In an optional embodiment, limiting blocks 221 are installed on both sides of the seat plate 212, and the bed body 1 has a groove inside, the size of which is adapted to the limiting blocks 221.

[0030] It should be noted that the groove inside the bed body 1 is a T-shaped groove that matches the cross-sectional shape of the limiting block 221. The limiting block 221 slides in the T-shaped groove, ensuring that the seat plate 212 moves linearly without deviation while reducing sliding friction resistance.

[0031] In an optional embodiment, one end of the extrusion rod 218 is provided with an extrusion head 220, and one end of the extrusion head 220 is movably connected to the inclined block 37.

[0032] It should be noted that the end face of the extrusion head 220 that contacts the inclined block 37 is an arc surface. When the seat plate 212 slides towards the tail of the bed, the arc surface of the extrusion head 220 rolls and slides along the inclined surface of the inclined block 37, converting the horizontal thrust of the seat plate 212 into a lifting torque on the leg plate 31, thereby lifting the leg plate 31.

[0033] In an optional embodiment, a mounting base 33 is provided at the bottom of the leg plate 31, and a second electric push rod 34 is mounted on the mounting base 33. The output end of the second electric push rod 34 is connected to a movable plate 35, and two sets of connecting rods 36 are mounted on the movable plate 35. One end of each set of connecting rods 36 is connected to the lifting seat 32.

[0034] It should be noted that the mounting base 33 is fixed to the bottom of the leg plate 31, and the cylinder of the second electric push rod 34 is bolted to the mounting base 33. The extension and retraction direction of the output end of the second electric push rod 34 is perpendicular to the bottom surface of the leg plate 31. The center of the movable plate 35 is fixedly connected to the output end of the second electric push rod 34. Two sets of connecting rods 36 are symmetrically installed on the movable plate 35. One end of the connecting rod 36 is hinged to the movable plate 35, and the other end is hinged to the lifting seat 32. The surface of the lifting seat 32 is covered with a medical silicone pad. The upper surface of the silicone pad has an arc-shaped groove that matches the curvature of the lower leg. When the second electric push rod 34 extends, it pushes the movable plate 35 away from the bottom surface of the leg plate 31. The movable plate 35 drives the lifting seat 32 to move away from the bottom surface of the leg plate 31 through the two sets of connecting rods 36. The lifting seat 32 supports the patient's lower leg from below and lifts it upward.

[0035] Working principle: When in use, the first electric push rod 21 is activated. Its output end pushes the back plate 22 to rotate upward around the first rotating shaft 24 through the flexible joint 23. When the first rotating shaft 24 rotates, it drives the gears 25 at both ends to rotate synchronously. The gears 25 mesh with the rack 26 and drive the rack 26 to move horizontally towards the tail of the bed. The rack 26 pushes the seat plate 212 together with the telescopic layer 213 inside it to slide towards the tail of the bed. At the same time, the telescopic layer 213 can always keep in contact with the leg plate 31 under the action of the elastic rod 217. The limiting blocks 221 on both sides of the seat plate 212 slide in the groove inside the bed body 1 to ensure that the seat plate 212 moves in a straight line without deflection. When the first electric push rod 21 pushes the upper section of the back plate 22 to rise, the elastic rope 28 is gradually tightened, generating a downward pulling force on the movable block 29. The movable block 29 overcomes the supporting force of the spring 211, slides backward and downward along the groove of the back plate 22 and tilts slightly upward. The movable block 29 moves backward and downward. When the seat 212 slides toward the foot of the bed, it drives the pressing rod 218 on its side to move synchronously. The pressing head 220 at the front end of the pressing rod 218 gradually contacts and presses the inclined block 37 at the bottom of the leg plate 31. After the inclined block 37 is pressed, it causes the leg plate 31 to tilt upward around its rotation connection point with the bed 1.

[0036] The second electric push rod 34 is activated, and through the movable plate 35 and two sets of connecting rods 36, it pushes the two sets of lifting seats 32 upward to lift the patient's lower leg, realizing a secondary lifting after the leg plate 31 is basically lifted upward.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
