Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of body measurement bed, in particular to a lying posture body measurement bed. BACKGROUND

[0002] The lying posture body measurement bed is a medical measurement device specially designed for bedridden patients, which integrates body weight and body shape parameter detection functions, senses the body weight of the patient through the pressure sensor array at the bottom of the bed body, and accurately measures the height of the patient in the supine position in combination with mechanical positioning structure and encoder components. The device does not require the patient to stand up, and can adapt to people who are not convenient to stand up, such as infants, critically ill patients, postoperative rehabilitation patients, etc.

[0003] The traditional measurement bed usually has a marking block that can slide on the top of the bed body. The height of the patient is calculated by recording the moving distance of the marking block. However, when the bed body is not in use, the marking block protrudes from the top of the bed body. The exposed hard object on the top of the bed body may cause safety hazards in the complex environment of the hospital. In actual use, when the patient needs to be moved to the bed body, the protruding hard object may cause bumps to the patient's body, thereby causing discomfort to the patient. Therefore, it is necessary to improve it. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a lying posture body measurement bed, which solves the problem that the position of the marking block cannot be adjusted in the existing device, resulting in a protrusion on the top of the bed surface, which increases the safety hazard and is not convenient for moving the patient to the bed surface.

[0005] To achieve the above purpose, the present application is realized by the following technical scheme: a lying posture body measurement bed, comprising a support seat, the bottom surface of the support seat is provided with a base, the inside of the base is provided with a pressure sensing array, and the bottom of the support seat extends into the inside of the base and is in contact with the pressure sensing array, the top surface of the support seat is fixedly installed with guide rods at the four corners, the top end of the guide rod is fixedly connected with a bed plate, the top surface of the bed plate is provided with a scale line, the inside of the bed plate is provided with an inner plate, the top of the inner plate is respectively provided with a first measurement block and a second measurement block, the two sides of the inner plate are fixedly connected with fixed blocks, the inside of the support seat is provided with a linkage assembly, and the linkage assembly is fixedly connected with the bed plate and the fixed blocks.

[0006] Through the above technical means: when in use, the height of the inner plate in the bed body can be controlled by the linkage assembly, and then the first measurement block and the second measurement block can be retracted into the inside of the bed plate when the bed body is not in use, so as to ensure the flatness of the bed plate surface, thereby reducing the occurrence of safety hazards, and facilitating the movement of the patient to the top of the bed plate, thereby enhancing the practicability in use.

[0007] Preferably, the linkage assembly includes a first threaded cylinder, a second threaded rod, a driving gear, a driven gear, a first sprocket, a second sprocket, a chain, a second threaded cylinder, and a first threaded rod. The second threaded rod is fixedly installed on the bottom surface of the bed board. The first threaded cylinder is sleeved on the outside of the second threaded rod. The driving gear is fixedly sleeved on the outside of the first threaded cylinder. The two driven gears are symmetrically arranged on both sides of the driving gear, and the driven gears are meshed with the driving gear. The first sprocket is fixedly installed on the top of the driven gear through a rod. The first threaded rod is fixedly installed on the bottom surface of the fixed block. The second threaded cylinder is sleeved on the outside of the first threaded rod. The second sprocket is fixedly installed at the bottom end of the second threaded cylinder. The chain is disposed between the first sprocket and the second sprocket.

[0008] Preferably, the support base is equipped with a first motor, and the output end of the first motor is connected to the drive gear.

[0009] Preferably, the support base is fixedly mounted with a housing on both sides, and the second threaded cylinder and the first threaded rod are disposed inside the housing.

[0010] Preferably, a movable seat is fixedly connected to the bottom surface of the first metering block, a screw is inserted inside the movable seat, and smooth rods are provided on both sides of the screw, with the smooth rods passing through the movable seat.

[0011] Preferably, the inner plate has a second motor inside, and the output end of the second motor is connected to the screw. The surface of the inner plate has a sliding groove, and the top of the movable seat extends into the inner side of the sliding groove.

[0012] Preferably, the first metering block has a telescopic rod inside, one end of which is fixedly connected to a stop block, and a telescopic spring inside which a pressure sensor is connected to one end.

[0013] Preferably, the bed board has movable grooves on both sides, and the fixing block extends into the interior of the movable groove.

[0014] Preferably, the top surface of the bed board is provided with a first docking groove, a second docking groove and a third docking groove in sequence, and the top surface of the inner board is symmetrically equipped with guardrails.

[0015] Preferably, a plurality of rollers are rotatably mounted on the top of the bed board.

[0016] Working principle: During use, the patient can be moved to the top of the bed board. By pulling the patient's limbs, the patient's head comes into contact with the second measuring block. The rolling of the rollers reduces the discomfort of pulling the patient. The second motor is turned on, which drives the screw to rotate. The screw drives the moving seat to move, and the moving seat drives the first measuring block to move, bringing the abutment block into contact with the patient's foot. The first measuring block is continuously moved, allowing it to move inward. At the same time, when the abutment block moves inward, the telescopic rod retracts, which in turn compresses the telescopic spring. The pressure sensor detects the elasticity of the telescopic spring, thus ensuring that the first measuring block is in contact with the patient's foot. The displacement distance of the first measuring block can be determined by the scale lines. By subtracting the displacement distance of the first measuring block from the initial position of the first and second measuring blocks, the patient's height data can be obtained. The pressure sensor array can detect the gravity data of the top component. When measuring the patient's weight, the weight data of the top component can be zeroed in advance. When the patient lies on the bed board, the patient's weight data can be measured. When the device is not in use, the first motor can be turned on. The first motor drives the first threaded cylinder to rotate, which in turn drives the second threaded rod to extend and retract, thereby controlling the downward movement of the bed board. Simultaneously, when the first threaded cylinder rotates, it drives the drive gear to rotate, which in turn drives the driven gears on both sides to rotate. The driven gears drive the first sprocket to rotate, which in turn drives the second sprocket to rotate via a chain. The second sprocket drives the second threaded cylinder to rotate, which in turn drives the first threaded rod to extend and retract. The first threaded rod can then drive the inner plate to rise and fall via a fixed block, raising and lowering the inner plate and the bed board to their lowest point. This allows the guardrail, the first metering block, and the second metering block to retract into the bed board, ensuring the flatness of the bed board top and reducing safety hazards.

[0017] This invention provides a bed for measuring body posture in a supine position. It has the following beneficial effects: 1. The present invention, through the setting of the linkage component, can control the height of the inner board inside the bed. When the bed is not in use, the inner board can be moved down to the lowest point inside the bed board, and the first and second measuring blocks can be retracted into the bed board, ensuring the flatness of the top of the bed board and preventing the protrusions on the top of the bed board from causing safety hazards or causing discomfort to the patient.

[0018] 2. When the linkage component controls the height of the inner panel, the height of the bed board can be controlled synchronously. Thus, when it is necessary to move the patient to the bed board, the height of the bed board can be at its lowest, making it convenient to move the patient to the top of the bed board. Furthermore, when the bed is not in use, the height of the bed board can be moved down synchronously when the inner panel is retracted, thereby reducing the space occupied by the bed and making it convenient to store.

[0019] 3. In this invention, through the cooperation between the telescopic spring and the pressure sensor, when the abutment block comes into contact with the patient, the abutment block retracts into the interior of the first measuring block, simultaneously squeezing the telescopic rod and thus squeezing the telescopic spring inward. The pressure sensor detects the telescopic spring's elastic force, thereby ensuring that the first measuring block is in contact with the patient's limb and guaranteeing the accuracy of the measurement.

Detailed Implementation

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0023] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 Appendix Figure 9 and attached Figure 10 This invention provides a recumbent body shape measurement bed, including a support base 1, a base 2 on the bottom surface of the support base 1, a pressure sensor array 34 inside the base 2, and the bottom of the support base 1 extending into the interior of the base 2 and contacting the pressure sensor array 34. Guide rods 6 are fixedly installed at the four corners of the top surface of the support base 1, and a bed board 3 is fixedly connected to the top of the guide rods 6. The top surface of the bed board 3 is provided with scale lines 9. An inner plate 10 is provided inside the bed board 3. A first measuring block 13 and a second measuring block 14 are respectively provided on the top of the inner plate 10. Fixing blocks 35 are fixedly connected to both sides of the inner plate 10. A linkage component is provided inside the support base 1, and the linkage component is fixedly connected to the bed board 3 and the fixing blocks 35 respectively.

[0024] Specifically, the pressure sensor array 34 can detect the pressure of its top component. A control panel is provided on one side of the bed board 3, and the pressure detected by the pressure sensor array 34 can be displayed on the control panel. In actual use, the patient can be lifted to the top of the bed board 3. Before measurement, the weight data can be zeroed in advance. When the patient is lifted to the top of the bed board 3, the patient's weight can be transmitted to the support seat 1. The support seat 1 can press down the pressure sensor array 34 inside the base 2, and the pressure sensor array 34 can detect the patient's weight data. The first measuring block 13 and the second measuring block 14 are on the same horizontal line. When detecting the patient's height, the patient's head can be brought into contact with the second measuring block 14, and then the first measuring block 13 can be moved to contact the patient's feet. The scale line 9 makes it easy for medical staff to judge the moving distance of the first measuring block 13. By subtracting the moving distance of the first measuring block 13 from the initial distance between the first measuring block 13 and the second measuring block 14, the patient's height data can be obtained, thus demonstrating the function of this measuring bed. Example 2:

[0025] When the first measuring block 13 and the second measuring block 14 are used to measure the patient's height, they protrude from the top of the bed board 3. When not in use, the protrusions cause unevenness in the bed board 3, which may pose a safety hazard in the complex environment of a hospital. Furthermore, when moving the patient onto the bed board 3, the protrusions may bump into the patient's limbs, causing discomfort. To solve this problem, this embodiment proposes the following structure based on the above embodiment: Please see the appendix Figure 5 The linkage assembly includes a first threaded cylinder 17, a second threaded rod 18, a driving gear 19, a driven gear 21, a first sprocket 22, a second sprocket 23, a chain 25, a second threaded cylinder 24, and a first threaded rod 7. The second threaded rod 18 is fixedly installed on the bottom surface of the bed plate 3. The first threaded cylinder 17 is sleeved on the outside of the second threaded rod 18. The driving gear 19 is fixedly sleeved on the outside of the first threaded cylinder 17. Two driven gears 21 are symmetrically arranged on both sides of the driving gear 19, and the driven gears 21 are meshed with the driving gear 19. The first sprocket 22 is fixedly installed on the top of the driven gear 21 through a rod. The first threaded rod 7 is fixedly installed on the bottom surface of the fixing block 35. The second threaded cylinder 24 is sleeved on the outside of the first threaded rod 7. The second sprocket 23 is fixedly installed on the bottom end of the second threaded cylinder 24. The chain 25 is disposed between the first sprocket 22 and the second sprocket 23.

[0026] Specifically, the first threaded cylinder 17 and the second threaded rod 18 are connected by threads, and the second threaded cylinder 24 and the first threaded rod 7 are connected by threads. Therefore, when the first threaded cylinder 17 and the second threaded cylinder 24 are rotated, and the second threaded rod 18 and the first threaded rod 7 are limited, they can be extended respectively. When the first threaded cylinder 17 rotates, it can extend the second threaded rod 18. When the second threaded rod 18 extends, it can push the bed plate 3 to rise and fall. Simultaneously, when the first threaded cylinder 17 rotates, it can drive the drive gear 19 to rotate. The drive gear 19 can drive the driven gears 21 on both sides to rotate, and the driven gears 21 can drive the first sprocket. When the first sprocket 22 rotates, the first sprocket 22 drives the second sprocket 23 to rotate via the chain 25. The second sprocket 23 drives the second threaded cylinder 24 to rotate, and the second threaded cylinder 24 drives the first threaded rod 7 to extend. The extension of the first threaded rod 7 pushes the fixed block 35 to rise and fall. The fixed block 35 drives the inner plate 10 to move inside the bed board 3. Furthermore, through conventional and reasonable design by industry professionals, the pitch of the second threaded rod 18 and the first threaded cylinder 17 is smaller than the pitch of the first threaded rod 7 and the second threaded cylinder 24. Therefore, when the driving gear 19 drives the first threaded cylinder 17 to rotate, it drives the second threaded rod 18 to extend, and through the driven gear 21, chain 25, first sprocket 22, and second sprocket 23, it drives... When the two second threaded cylinders 24 rotate to extend the first threaded rod 7, the threaded rod with a larger pitch moves axially faster, while the threaded rod with a smaller pitch extends slower. Therefore, the extension rate of the first threaded rod 7 is slightly greater than that of the second threaded rod 18. Consequently, when the second threaded rod 18 pushes the bed board 3 to rise at a speed less than the speed at which the first threaded rod 7 pushes the inner plate 10 to rise, in this embodiment, when the second threaded rod 18 pushes the bed board 3 to its maximum height, the first threaded rod 7 can simultaneously push the inner plate 10 to the highest point inside the bed board 3 via the fixing block 35. This ensures that the guardrail 36 can extend to the top surface of the bed board 3, preventing the guardrail 36 from extending too far due to the consistent lifting speed of the inner plate 10 and the bed board 3. In cases where the extension is not possible, similarly, when the bed is not in use, the inner panel 10 can be lowered to the lowest point inside the bed board 3, thereby allowing the first measuring block 13 and the second measuring block 14 to retract into the bed board 3. This ensures the flatness of the top surface of the bed board 3, reducing safety hazards. At the same time, when moving a patient onto the bed board 3, the flatness of the bed board 3 surface prevents protruding objects from causing bumps to the patient, enhancing the practicality of the device. Furthermore, when the inner panel 10 is lowered to the lowest point inside the bed board 3, the bed board 3 is at its lowest point, making it easier for medical staff to move the patient to the top surface of the bed board 3. Additionally, when not in use, the bed board 3 is at its lowest point, reducing the floor space required and facilitating storage.

[0027] Please see the appendix Figure 1 and attached Figure 5The support base 1 is equipped with a first motor 20, and the output end of the first motor 20 is connected to the drive gear 19. The support base 1 is fixedly installed with a housing 5 on both sides, and the second threaded cylinder 24 and the first threaded rod 7 are arranged inside the housing 5.

[0028] Specifically, by activating the first motor 20, the first threaded cylinder 17 can be rotated. The second sprocket 23 is rotatably mounted inside the outer casing 5 via a rotating shaft, thus ensuring the stability of the transmission of the second sprocket 23. The first threaded cylinder 17 is rotatably mounted inside the outer casing 5, thus ensuring the normal extension and retraction of the first threaded rod 7 inside the outer casing 5. The guide rod 6 is extendable, so when the bed board 3 is raised or lowered, it can drive the guide rod 6 to extend or retract, thereby increasing the stability and directional accuracy of the bed board 3 during raising and lowering. Rods are fixedly mounted at the bottom ends of the second sprocket 23 and the first sprocket 22. A bearing is connected to the bottom end of the rod, which is installed inside the housing 5. When the second threaded cylinder 24 rotates, the rod at the bottom end of the second sprocket 23 and the first sprocket 22 can rotate within the bearing, increasing the stability of the second threaded cylinder 24 when it rotates. The first threaded cylinder 17 is rotatably connected to the bed plate 3, and a bearing for fixing the first threaded cylinder 17 is provided at the connection between the first threaded cylinder 17 and the bed plate 3. When the drive gear 19 drives the first threaded cylinder 17 to rotate, the first threaded cylinder 17 can rotate stably inside the bed plate 3.

[0029] Please see the appendix Figure 6 The bottom surface of the first measuring block 13 is fixedly connected to a movable seat 26. A screw 27 is inserted inside the movable seat 26. Smooth rods 28 are provided on both sides of the screw 27 and are inserted through the movable seat 26. A second motor 29 is provided inside the inner plate 10, and the output end of the second motor 29 is connected to the screw 27. A sliding groove 12 is opened on the surface of the inner plate 10, and the top of the movable seat 26 extends into the inner side of the sliding groove 12.

[0030] Specifically, the movable seat 26 and the screw 27 are connected by a thread, so when the screw 27 rotates, it can drive the movable seat 26 to move. When the movable seat 26 moves, it can drive the first measuring block 13 to move. When in use, the movable seat 26 drives the first measuring block 13 to move. The first measuring block 13 contacts the patient's foot. The displacement distance of the first measuring block 13 can be determined by the scale line 9. By subtracting the displacement distance of the first measuring block 13 from the initial distance between the first measuring block 13 and the second measuring block 14, the patient's height data can be obtained. The smooth rod 28 and the movable seat 26 are connected by a sliding connection, so when the screw 27 rotates and drives the movable seat 26 to move, the movable seat 26 can slide on the smooth rod 28, thus ensuring the stability and directionality of the movable seat 26 when moving, and directly increasing the stability of the first measuring block 13 when moving.

[0031] Please see the appendix Figure 7and attached Figure 8 The first measuring block 13 has a telescopic rod 31 inside, one end of which is fixedly connected to a stop block 30. The telescopic rod 31 has a telescopic spring 32 inside, and one end of the telescopic spring 32 is connected to a pressure sensor 33.

[0032] Specifically, when the first measuring block 13 is moved, the abutment block 30 can come into contact with the patient's foot. When the abutment block 30 is in contact with the patient's foot, continuous movement of the first measuring block 13 can cause the abutment block 30 to press inward against the telescopic rod 31. The telescopic rod 31 can press inward against the telescopic spring 32. The pressure sensor 33 can detect the telescopic force of the telescopic spring 32. When the abutment block 30 retracts to overlap with the first measuring block 13, the pressure sensor 33 can detect the retraction of the abutment block 30 and transmit it to the control panel for display via an electrical signal. This ensures that the first measuring block 13 is in contact with the patient's foot, thus ensuring the accuracy of measuring the patient's height.

[0033] Please see the appendix Figure 1 and attached Figure 2 The bed board 3 has movable grooves 4 on both sides, and the fixing block 35 extends into the interior of the movable groove 4. The top surface of the bed board 3 has a first docking groove 11, a second docking groove 15 and a third docking groove 16 in sequence. The top surface of the inner board 10 is symmetrically equipped with guardrails 36.

[0034] Specifically, the installation position of the guardrail 36 corresponds to the third docking groove 16, the position of the sliding groove 12 and the first metering block 13 corresponds to the position of the first docking groove 11, and the position of the second metering block 14 corresponds to the position of the second docking groove 15. Thus, when the inner plate 10 moves inside the bed board 3, the first metering block 13 can extend out from inside the first docking groove 11, the second metering block 14 can extend out from the second docking groove 15, and the guardrail 36 can extend out from inside the third docking groove 16. This ensures the normal lifting and lowering of the inner plate 10 inside the bed board 3, and also allows the first metering block 13 to move normally on the top of the bed board 3.

[0035] Please see the appendix Figure 1 Multiple rollers 8 are rotatably mounted on the top of the bed board 3.

[0036] Specifically, the roller 8 is rotatably mounted on the top of the bed board 3. When the patient lies on the bed board 3, the patient's limbs can be pulled. Through the rolling of the roller 8, the patient can move easily on the top of the bed board 3, thereby facilitating the adjustment of the patient's position and making it easier for the patient's head to contact the second measuring block 14, thus facilitating the detection of the patient's height.

[0037] This embodiment provides a supine body measurement bed. In use, the patient can be moved to the top of the bed board 3. By pulling the patient's limbs, the patient's head comes into contact with the second measuring block 14. The rolling of the roller 8 reduces the discomfort of pulling the patient. The second motor 29 is activated, driving the screw 27 to rotate. The screw 27 moves the moving seat 26, which in turn moves the first measuring block 13, bringing the abutment block 30 into contact with the patient's feet. Continuing to move the first measuring block 13 further causes the abutment block 30 to... When the first measuring block 13 moves inward, the telescopic rod 31 can retract when the abutment block 30 moves inward towards the first measuring block 13. The telescopic rod 31 can compress the telescopic spring 32 inward, and the pressure sensor 33 can detect the elastic force of the telescopic spring 32, thereby ensuring that the first measuring block 13 is in contact with the patient's foot. The displacement distance of the first measuring block 13 can be determined by the scale line 9. The patient's height data can be obtained by subtracting the displacement distance of the first measuring block 13 from the initial position of the first measuring block 13 and the second measuring block 14. The pressure sensor array 34 can detect the gravity data of the top device. When measuring the patient's weight, the weight data of the top device can be zeroed in advance. When the patient lies on the bed board 3, the patient's weight data can be measured. When the device is not in use, the first motor 20 can be turned on. The first motor 20 drives the first threaded cylinder 17 to rotate, and the first threaded cylinder 17 drives the second threaded rod 18 to extend and retract, thereby controlling the downward movement of the bed board 3. Simultaneously, when the first threaded cylinder 17 rotates, it drives the drive gear 19 to rotate. The drive gear 19 drives the driven gears 21 on both sides to rotate. The driven gears 21 drive the first sprocket 22 to rotate. The first sprocket 22 drives the second sprocket 23 to rotate via the chain 25. The second sprocket 23 drives the second threaded cylinder 24 to rotate. The second threaded cylinder 24 drives the first threaded rod 7 to extend and retract. The first threaded rod 7 drives the inner plate 10 to rise and fall via the fixing block 35, raising and lowering the inner plate 10 and the bed board 3 to the lowest point. This allows the guardrail 36, the first metering block 13, and the second metering block 14 to retract into the interior of the bed board 3, ensuring the flatness of the top of the bed board 3 and reducing safety hazards.

[0038] 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.
