Description

Technical Field

[0001] This application relates to the field of nursing bed technology, and more particularly to a bed for bedridden patients with excretion care functions. Background Technology

[0002] With the increasing aging of the population and the rising prevalence of chronic diseases, the number of long-term bedridden patients is increasing year by year. For bedridden patients who have lost the ability to move independently, excretion care is one of the most frequent, labor-intensive, and dignified aspects of daily care.

[0003] Currently, there are various nursing beds on the market with excretion care functions. These beds typically have an excretion hole on the bed board corresponding to the patient's buttocks, and a removable bedpan is installed below the hole. When the patient needs to defecate, the caregiver manually or electrically moves the bedpan directly below the excretion hole, and the patient can then directly empty the waste into the bedpan, thus avoiding the difficulty of getting up to use the toilet.

[0004] The aforementioned technology of nursing beds with excretion care functions has a problem: nursing beds typically consist of a mattress and a bed frame. If the patient lies directly on the mattress, part of the mattress can be made movable, but this makes the mattress difficult to clean and unsuitable for use in public places. If the patient lays a sheet on the mattress, the sheet will still interfere with the patient's excretion process even after the mattress is moved. Summary of the Invention

[0005] This application provides a bed for bedridden patients with excretion care function, which can improve the technical problems in related technologies where the bed sheet needs to be manually removed before the patient urinates and manually re-laid on the mattress after urination.

[0006] This application provides a bed for bedridden patients with excretion care functions, including: The main body of the hospital bed includes a backrest, a seat, and a leg rest. One end of the seat is hinged to the backrest, and the other end is hinged to the leg rest. A partitioned mattress is installed on the main body of the hospital bed; A bed sheet is laid on the partitioned mattress; A manure bucket, movably disposed below the leg plate, is used to collect manure; and A bed sheet moving mechanism, a portion of which is fixed to one end of the backrest portion away from the seat portion, and another portion which is movably disposed on one end of the leg plate portion away from the seat portion; the bed sheet moving mechanism is used to move the bed sheet away from the seat plate portion and the leg plate portion so that the patient can directly face the septic tank for defecation; The bed sheet moving mechanism is used to rotate the bed sheet on the seat and leg panels to the backrest when the seat and leg panels are rotated away from the ground, so that there is no bed sheet above the seat when the patient adjusts the sitting position, thereby preventing the bed sheet from being contaminated by the patient during defecation.

[0007] The technical solutions described in this application embodiment have at least the following technical effects: This application provides a bed for bedridden patients with excretion care functions. The bed body is divided into three parts: a rotatable backrest, a seat, and a legrest. This allows the bed to have two states: a first state for the patient to lie flat, and a second state for the patient to excrete. This design helps patients adjust their posture, easily transitioning from a lying position to a sitting position for excretion. The mattress is a partitioned mattress to accommodate the three-part bed body. A movable chamber pot is positioned under the push-up panel, allowing it to move to the seat when the bed is in the second state. This design allows family members to place the chamber pot in the legrest instead of the relatively distant seat. A sheet-moving mechanism allows the sheet above the seat to be moved to the hinge between the backrest and seat before the bed is in the first state, preventing soiling of the sheet during excretion.

[0008] In some embodiments, the sheet moving mechanism includes: A guide member, comprising a seat plate guide member and a leg plate guide member, wherein the seat plate guide member is disposed on one side of the seat plate portion and the leg plate guide member is disposed on one side of the leg plate portion, and the seat plate guide member and the leg plate guide member are located on the same straight line when the seat plate portion and the leg plate portion are in the same plane; A guide roller is movably mounted on the main body of the hospital bed, and one end of the bed sheet is fixed to the guide roller; and A power unit is movably mounted on the guide member, and the power output end of the power unit is connected to the guide roller; The power unit is used to drive the guide roller to rotate in the winding direction when the seat plate and the leg plate rotate away from the ground, so that the bed sheet is wound onto the guide roller, and at the same time drive the guide roller to move along the guide member towards the back plate member.

[0009] In some embodiments, the sheet moving mechanism further includes a rack and a gear. The rack includes a first tooth segment and a second tooth segment. The first tooth segment is disposed on the side of the seat plate portion away from the seat plate guide, and the second tooth segment is disposed on the side of the leg plate portion away from the leg plate guide. The straight line of the first tooth segment is parallel to the straight line of the seat plate guide, and the straight line of the second tooth segment is parallel to the straight line of the leg plate guide. The gear is disposed at the end of the guide roller away from the power device.

[0010] In some embodiments, a drainage hole is provided on the seat portion, and the partitioned mattress includes a fixed pad and a movable pad. One end of the movable pad is fixed to the back panel portion, and the movable pad is used to form a complete mattress with the fixed pad when the back panel portion and the seat portion are on the same plane. The movable pad is also used to completely move above the drainage hole when the back panel portion and the seat portion are at a right angle, so that the patient can use the drainage hole to defecate without affecting the movable pad. The fixed pad is located in other positions of the main body of the bed.

[0011] In some embodiments, the backrest portion is moved away from the seat portion to create a certain distance between the backrest portion and the seat portion, thereby preventing the partitioned mattresses from abutting each other and allowing the bedridden patient bed to be folded normally.

[0012] In some embodiments, the bed for bedridden patients further includes a linkage mechanism, one end of which is connected to the end of the guide roller away from the power device, and the other end is detachably mounted on the feces bucket. The linkage mechanism is used to associate the position of the feces bucket with the position of the guide roller, so that the power device can bring the feces bucket directly below the discharge hole via the guide roller.

[0013] In some embodiments, the guide roller has a protruding rod at the end away from the power unit, and an annular groove is formed on the side wall of the protruding rod. The linkage mechanism includes: A connector, fitted within the annular groove, is designed to move with the protruding rod but not rotate with it; and A locking element, one end of which is connected to the connector, and the other end of which is used to cooperate with the feces bucket so that the feces bucket can be fixed on the locking element; The locking member is used to cooperate with the feces bucket when the included angle between the seat plate and the leg plate is 90 degrees, so that the feces bucket is fixed on the locking member, thereby enabling the power device to drive the feces bucket directly below the discharge hole through the connecting member and the guide roller.

[0014] In some embodiments, the locking element includes a first locking rod and a second locking rod, the first locking rod, the second locking rod and the guide roller are located on the same plane, and the first locking rod and the second locking rod both cooperate with one side of the feces bucket so that the feces bucket can be stably located directly below the discharge hole.

[0015] In some embodiments, the waste container includes: The toilet body is detachably disposed below the leg plate portion, and the toilet body has a first mating hole, a second mating hole and an excretion space. The first mating hole and the second mating hole are both disposed on the side of the toilet body away from the leg plate portion, and the excretion space is disposed on the side of the toilet body close to the seat plate portion. Two locking fittings are movably disposed on the sidewalls of the first fitting hole and the second fitting hole, respectively; A locking motor is mounted on the toilet bowl body, and the power output end of the locking motor is simultaneously connected to two locking mating parts; and Two distance sensors are respectively installed on the bottom wall of the first mating hole and the second mating hole; When both distance sensors detect that the distances from the two locking components are within a predetermined distance, the locking motor pushes the two locking components to move away from the locking motor, so that the two locking components restrict the first locking rod and the second locking rod in the first mating hole and the second mating hole respectively, thereby allowing the toilet body to be fixed on the locking components.

[0016] In some embodiments, the bedridden patient bed further includes a control unit electrically connected to the power unit and the feces container; the control unit is configured to perform the following control steps upon receiving excretion information: The seat plate portion is controlled to move away from the back plate portion by a preset distance to form a folding clearance gap; The seat plate is controlled to rotate away from the ground, while the seat plate and the leg plate are kept on the same plane at all times. The power unit is controlled to drive the guide roller to move along the bed to the connection position between the seat plate and the leg plate. Control the leg plate to rotate toward the ground, so that the feces bucket is fixed on the guide roller; The power unit is controlled to drive the guide rollers to move along the bed to the connection between the back panel and the seat, thereby bringing the bed sheet to the connection and simultaneously bringing the manure bucket directly below the discharge hole; and Control the seat and backrest to adjust the bed for bedridden patients to a sitting position.

Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0027] With the increasing aging of the population and the rising prevalence of chronic diseases, the number of long-term bedridden patients is increasing year by year. For bedridden patients who have lost the ability to move independently, excretion care is one of the most frequent, labor-intensive, and dignified aspects of daily care.

[0028] Currently, there are various nursing beds on the market with excretion care functions. These beds typically have an excretion hole on the bed board corresponding to the patient's buttocks, and a removable bedpan is installed below the hole. When the patient needs to defecate, the caregiver manually or electrically moves the bedpan directly below the excretion hole, and the patient can then directly empty the waste into the bedpan, thus avoiding the difficulty of getting up to use the toilet.

[0029] The aforementioned technology of nursing beds with excretion care functions has a problem: nursing beds typically consist of a mattress and a bed frame. If the patient lies directly on the mattress, part of the mattress can be made movable, but this makes the mattress difficult to clean and unsuitable for use in public places. If the patient lays a sheet on the mattress, the sheet will still interfere with the patient's excretion process even after the mattress is moved.

[0030] Based on this, in order to improve the problem in related technologies that patients need to manually remove the sheets before defecating and manually put the sheets back on the mattress after defecating, the embodiments of this application provide the following solutions.

[0031] Please refer to the following: Figures 1 to 4 This application provides a bed 100 for bedridden patients with excretion care functions. The bed 100 includes a bed body 10, a partitioned mattress 20, a bedpan 30, and a bed sheet moving mechanism 40, wherein: The main body 10 of the hospital bed includes a backrest 11, a seat 12 and a leg rest 13. One end of the seat rest 12 is hinged to the backrest 11 and the other end is hinged to the leg rest 13.

[0032] The partitioned mattress 20 is installed on the main body of the hospital bed 10.

[0033] The sheet is placed on the partitioned mattress 20.

[0034] The feces bucket 30 is movably disposed below the leg plate 13 for collecting feces.

[0035] A portion of the sheet moving mechanism 40 is fixed to one end of the backrest 11 away from the seat 12, and another portion is movably disposed on one end of the leg rest 13 away from the seat 12; the sheet moving mechanism 40 is used to remove the sheets on the seat 12 and the leg rest 13 so that the patient can defecate directly into the latrine 30.

[0036] The sheet moving mechanism 40 is used to rotate the sheets on the seat 12 and leg 13 to the backrest 11 when the seat 12 and leg 13 are rotated away from the ground, so that there are no sheets on the seat 12 when the patient adjusts his sitting position, thereby preventing the sheets from being soiled by the patient during defecation.

[0037] It is understood that the backrest 11, seat 12, and legrest 13 are all part of the main body 10 of the hospital bed. For example, the backrest 11 includes a backrest, a first stepper motor, and a linear motor, etc., with the partitioned mattress 20 partially located on the backrest. The end of the backrest near the seat 12 is connected to the power output of the first stepper motor. The linear motor is located on the side of the backrest facing the ground, and its power output is connected to the bed frame. For example, the seat 12 includes a seat and a second stepper motor, with the partitioned mattress 20 partially located on the seat, which is positioned on the power output of the second stepper motor. For example, the legrest 13 includes a leg and a third stepper motor, with the partitioned mattress 20 partially located on the leg, which is connected to the power output of the third stepper motor. The partitioned mattress 20 is a mattress used in conjunction with the foldable bedridden patient bed 100 in this solution. The chamber pot 30 is a component used to collect feces; for example, the chamber pot 30 can be a plastic bucket. As another example, the chamber pot 30 includes a main body 31, two locking fittings 32, a locking motor 33, and two distance sensors, etc. The sheet moving mechanism 40 is a component used to remove the sheet from the seat plate 12 and leg plate 13; for example, the sheet moving mechanism 40 includes a guide 41, guide rollers 42, and a power unit 43, etc.

[0038] As can be seen from the above, the bed 100 for bedridden patients with excretion care function provided in this application embodiment divides the main body 10 of the bed into three parts: a rotatable backrest 11, a seat 12, and a leg rest 13. This allows the bed 100 to have two states: a first state adapted to the patient lying flat, and a second state adapted to the patient excretion. The bed 100 of the above solution can help the patient adjust their posture, so that the patient can easily change from a resting lying position to a sitting position for excretion. By setting the mattress as a partitioned mattress 20, it can accommodate the three-part bed body 10. By movably setting the bedpan 30 under the push board, the bedpan 30 can be moved to under the seat 12 when the bed 100 is transformed into the second state. This solution makes it easier for family members to place the bedpan 30 under the leg rest 13, rather than the relatively far seat 12. By setting up a bed sheet moving mechanism 40, the bed sheet located above the seat board 12 can be moved to the hinge point between the backrest 11 and the seat board 12 before the bedridden patient bed 100 is converted to the first state, thereby preventing the bed sheet from being soiled during the patient's excretion.

[0039] In some embodiments, please refer to the following: Figures 1 to 4 The bed sheet moving mechanism 40 includes a guide 41, a guide roller 42, and a power unit 43, wherein: The guide member 41 includes a seat plate guide and a leg plate guide. The seat plate guide is disposed on one side of the seat plate portion 12, and the leg plate guide is disposed on one side of the leg plate portion 13. The seat plate guide and the leg plate guide are located on the same straight line when the seat plate portion 12 and the leg plate portion 13 are on the same plane.

[0040] The guide roller 42 is movably mounted on the main body 10 of the hospital bed, and one end of the bed sheet is fixed to the guide roller 42.

[0041] The power unit 43 is movably mounted on the guide member 41, and the power output end of the power unit 43 is connected to the guide roller 42.

[0042] The power unit 43 is used to drive the guide roller 42 to rotate in the winding direction when the seat plate 12 and leg plate 13 are rotating away from the ground, so that the bed sheet is wound onto the guide roller 42, and at the same time drive the guide roller 42 to move along the guide member 41 towards the back plate member.

[0043] It can be understood that the guide member 41 is a component that works in conjunction with the power unit 43 to guide the rotation of the guide roller 42; for example, the guide member 41 can be a metal rod or a plastic rod, etc. The guide roller 42 is a component used to assist in collecting bed sheets. The power unit 43 is a device used to provide power to the guide roller 42; for example, the power unit 43 can be a servo motor or a stepper motor, etc.

[0044] This configuration, with the guide members 41 positioned separately on the sides of the seat plate 12 and leg plate 13, allows the guide rails to automatically align or form an angle as the bed frame is folded and flattened, perfectly adapting to the geometric changes of the hospital bed in both lying and sitting positions. By movably mounting the guide roller 42 on the guide member 41 and fixing one end of the sheet to the guide roller 42, the power unit 43 drives the guide roller 42 to rotate in the winding direction and simultaneously move it along the guide member 41 towards the backrest 11, achieving a simultaneous moving and retracting sheet-collecting action.

[0045] Optionally, in some embodiments, please refer to Figures 1 to 4 The bed sheet moving mechanism 40 also includes a rack 45 and a gear 46. The rack 45 includes a first tooth segment 451 and a second tooth segment 452. The first tooth segment 451 is located on the side of the seat plate portion 12 away from the seat plate guide, and the second tooth segment 452 is located on the side of the leg plate portion 13 away from the leg plate guide. The straight line of the first tooth segment 451 is parallel to the straight line of the seat plate guide, and the straight line of the second tooth segment 452 is parallel to the straight line of the leg plate guide. The gear 46 is located at the end of the guide roller 42 away from the power unit 43.

[0046] It is understood that the rack 45 and the gear 46 are components that provide the force carrier for the movement of the power unit 43 and the guide roller 42.

[0047] This configuration, by setting the rack 45 as a first tooth segment 451 and a second tooth segment 452 respectively located on the seat plate portion 12 and the leg plate portion 13, and making the first tooth segment 451 parallel to the seat plate guide and the second tooth segment 452 parallel to the leg plate guide, ensures that the gear 46 maintains a stable meshing relationship with the rack 45 throughout its movement along the guide member 41. The guide roller 42 is driven to move along the bed body through the meshing transmission of the gear 46 and rack 45. This means that the traction force required for the movement of the guide roller 42 is mainly borne by the gear 46 and rack 45 pair, rather than by the bed sheet. The bed sheet is merely the object being rolled up, passively wound along with the movement of the guide roller 42, avoiding the risks of stretching deformation, tearing, or slippage from the guide roller 42 caused by direct force on the bed sheet. This significantly improves the reliability of the bed sheet winding action and the service life of the bed sheet itself.

[0048] Optionally, please refer to Figures 1 to 4The seat plate 12 has a drain hole 120. The partitioned mattress 20 includes a fixed pad 21 and a movable pad 22. One end of the movable pad 22 is fixed to the back plate 11. The movable pad 22 is used to form a complete mattress with the fixed pad 21 when the back plate 11 and the seat plate 12 are on the same plane. The movable pad 22 is also used to completely move out of the drain hole 120 when the back plate 11 and the seat plate 12 are at a right angle, so that the patient can use the drain hole 120 to defecate without affecting the movable pad 22. The fixed pad 21 is located in other positions of the bed body 10.

[0049] This configuration, by dividing the partitioned mattress 20 into two parts, a fixed pad 21 and a movable pad 22, with one end of the movable pad 22 fixed to the backrest 11, creates a mechanical linkage between the displacement of the movable pad 22 and the flipping motion of the backrest 11. In a supine position where the backrest 11 and seat 12 are on the same plane, the movable pad 22 automatically extends into and fills the drainage hole 120 on the seat 12, forming a complete and flat support plane together with the fixed pad 21. The patient will not feel the drainage hole 120 while lying down, ensuring a comfortable sleep experience. When the backrest 11 is flipped upwards to a sitting position approximately perpendicular to the seat 12, the lower end of the backrest 11 moves backwards, causing the movable pad 22 to be completely withdrawn from above the drainage hole 120, fully opening the drainage channel and allowing the patient to urinate directly downwards. Throughout this process, the movable pad 22 requires no independent drive source. This non-powered follow-up design eliminates the cost, noise, and potential for failure associated with configuring a separate motor for sealing / opening the drain hole 120. Furthermore, the mechanical forced linkage ensures that the opening and closing of the drain hole 120 is strictly synchronized with the patient's position changes, fundamentally preventing accidents caused by forgetting to open the sealing device and resulting in excrement contaminating the mattress.

[0050] For example, please refer to Figures 1 to 4 The backrest 11 is used to move away from the seat 12 so that a certain distance is created between the backrest 11 and the seat 12, thereby preventing the partitioned mattresses 20 from abutting each other, and allowing the bedridden patient bed 100 to be folded normally.

[0051] This configuration, by positioning the backrest 11 to move a predetermined distance away from the seat 12 before the folding action begins, creates a clear folding clearance between the backrest 11 and the seat 12. This clearance provides ample space to accommodate the bending deformation of the thick, partitioned mattress 20 during folding. Specifically, when the backrest 11 flips upwards, the ends of adjacent mattress panels will not come into contact and experience rigid compression, thus avoiding problems such as the folding motor stalling or overloading due to the mattress pressing against the surface. This clearance ensures smooth folding action, reduces the load on the folding drive mechanism, extends the lifespan of the mattress and mechanical structure, and maintains stability and reliability during repeated switching between lying and sitting positions.

[0052] In some embodiments, please refer to Figures 1 to 4 The bed for bedridden patients 100 also includes a linkage mechanism 50. One end of the linkage mechanism 50 is connected to the end of the guide roller 42 away from the power unit 43, and the other end is detachably mounted on the feces bucket 30. The linkage mechanism 50 is used to connect the position of the feces bucket 30 with the position of the guide roller 42 so that the power unit 43 can bring the feces bucket 30 directly below the discharge hole 120 through the guide roller 42.

[0053] It can be understood that the linkage mechanism 50 is a mechanism used to connect the movement of the manure bucket 30 with the movement of the guide roller 42; for example, the linkage mechanism 50 includes a connector 51 and a locking member 52, etc.

[0054] With this configuration, a linkage mechanism 50 is set up, with one end connected to the end of the guide roller 42 facing away from the power unit 43, and the other end detachably connected to the waste container 30. During the process of the power unit 43 driving the guide roller 42 to move along the bed body towards the back panel 11 to roll up the bed sheet, the guide roller 42 simultaneously drives the waste container 30 to move along the bed body via the linkage mechanism 50, so that the waste container 30 automatically reaches directly below the discharge hole 120. This design eliminates the need for a separate drive source for the waste container 30, instead reusing the power of the bed sheet moving mechanism 40, reducing the number of motors and transmission components required for the entire machine, and lowering system complexity and manufacturing costs. Simultaneously, because the movement of the waste container 30 is strictly synchronized with the movement of the guide roller 42, the positioning action of the waste container 30 and the bed sheet's avoidance action are naturally coordinated. The detachable connection also allows the waste container 30 to be easily separated from the linkage mechanism 50 when cleaning or replacement is needed.

[0055] Optionally, in some embodiments, please refer to Figures 1 to 4 The guide roller 42 has a protruding rod 44 at the end away from the power unit 43. An annular groove 440 is formed on the side wall of the protruding rod 44. The linkage mechanism 50 includes a connecting member 51 and a locking member 52, wherein: The connector 51 is fitted inside the annular groove 440. The connector 51 is used to move with the protruding rod 44, but will not rotate with the protruding rod 44.

[0056] One end of the locking member 52 is connected to the connector 51, and the other end is used to cooperate with the feces bucket 30 so that the feces bucket 30 can be fixed on the locking member 52.

[0057] The locking member 52 is used to cooperate with the feces bucket 30 when the included angle between the seat plate portion 12 and the leg plate portion 13 is 90 degrees, so that the feces bucket 30 is fixed on the locking member 52, thereby enabling the power unit 43 to drive the feces bucket 30 directly below the discharge hole 120 through the connecting member 51 and the guide roller 42.

[0058] It is understood that the connecting member 51 is a component used to connect the locking member 52 to the guide roller 42; for example, the connecting member 51 includes a metal ring and a metal rod, the metal ring being fitted inside the annular groove 440, and the metal rod being connected to the side wall of the metal ring. The locking member 52 is a component used to connect the manure bucket 30 to the guide roller 42; for example, the locking member 52 can be a metal rod or a metal bar, etc.

[0059] This configuration, with a protruding rod 44 featuring an annular groove 440 at the end of the guide roller 42 furthest from the power unit 43, and the connector 51 fitted within the annular groove 440, allows the connector 51 to move synchronously with the guide roller 42 along the longitudinal direction of the bed, but it will not rotate with the guide roller 42 when it rotates to roll up the bed sheet. While driving the guide roller 42 to complete the bed sheet roll-up, the power unit 43 can smoothly drag the feces bucket 30 directly below the discharge hole 120, eliminating the need for a separate motion conversion mechanism between rotation and translation for the feces bucket 30. The engagement between the annular groove 440 and the connector 51 is purely mechanical, without electrical components, resulting in high reliability. It maintains stable motion transmission performance even under long-term, frequent use of the nursing bed, and is inexpensive to manufacture and easy to assemble and maintain.

[0060] Optionally, please refer to Figures 1 to 4 The locking element 52 includes a first locking rod 521 and a second locking rod 522. The first locking rod 521, the second locking rod 522 and the guide roller 42 are located on the same plane. The first locking rod 521 and the second locking rod 522 are both engaged with one side of the feces bucket 30 so that the feces bucket 30 can be stably located directly below the discharge hole 120.

[0061] This configuration, by setting the locking element 52 as a first locking rod 521 and a second locking rod 522, and ensuring that both locking rods are located on the same side of the feces bucket 30, forms a dual-point constraint on the same side. When the guide roller 42 moves the feces bucket 30 via the linkage mechanism 50, the first locking rod 521 and the second locking rod 522 are inserted into their corresponding mating holes from the same side of the feces bucket 30, and the feces bucket 30 is subjected to two spaced-apart constraint forces on the same plane. Since the straight line containing the two locking rods is coplanar with the position of the guide roller 42, the feces bucket 30 cannot rotate around either the first locking rod 521 or the second locking rod 522. Throughout the entire transfer process and when reaching directly below the discharge hole 120, the feces bucket 30 maintains precise alignment of the discharge space 312. This purely mechanical anti-rotation solution eliminates the need for additional auxiliary supports or guide structures on the other side of the feces bucket 30.

[0062] In some embodiments, please refer to Figures 1 to 4 The latrine bucket 30 includes a bucket body 31, two locking fittings 32, a locking motor 33, and two distance sensors, wherein: The toilet body 31 is detachably disposed below the leg plate portion 13, and the toilet body 31 is provided with a first mating hole 310, a second mating hole 311 and an excretion space 312. The first mating hole 310 and the second mating hole 311 are both disposed on the side of the toilet body 31 away from the leg plate portion 13, and the excretion space 312 is disposed on the side of the toilet body 31 near the seat plate portion 12.

[0063] Two locking fittings 32 are movably disposed on the sidewalls of the first mating hole 310 and the second mating hole 311, respectively.

[0064] The locking motor 33 is mounted on the toilet bowl body 31, and the power output end of the locking motor 33 is simultaneously connected to two locking mating parts 32.

[0065] Two distance sensors are respectively installed on the inner bottom wall of the first mating hole 310 and the second mating hole 311.

[0066] When the two distance sensors detect that the distances from the two locking engagement parts 32 are both within a predetermined distance, the locking motor 33 is used to push the two locking engagement parts 32 to move away from the locking motor 33, so that the two locking engagement parts 32 restrict the first locking rod 521 and the second locking rod 522 in the first mating hole 310 and the second mating hole 311 respectively, thereby allowing the toilet body 31 to be fixed on the locking parts 52.

[0067] It is understood that the bedpan body 31 is a component used to collect patient excrement; for example, the bedpan body 31 can be a plastic tube or a metal tube, etc. The locking engagement member 32 is a component used to confine the first locking member 52 within the first engagement hole 310 and the second locking member 52 within the second engagement hole 311; for example, the locking engagement member 32 can be a metal rod or a metal bar, etc. The locking motor 33 is a component used to drive the movement of the two locking engagement members 32; for example, the locking motor 33 can be a linear motor or a cylinder, etc. The distance sensor is a component used to detect the positions of the first locking member 52 and the second locking member 52.

[0068] This configuration involves creating a first mating hole 310 and a second mating hole 311 on the toilet body 31. Distance sensors are installed on the bottom walls of these holes, and movable locking components 32 are installed on the side walls. A locking motor 33 simultaneously drives both locking components 32. When the first locking rod 521 and the second locking rod 522 are inserted into the first and second mating holes 310 and 311 respectively, the two distance sensors continuously monitor the distance between the locking components 32 and the bottom of the holes. Only when both distance sensors confirm that the locking rods have been inserted to the predetermined depth does the locking motor 33 drive the two locking components 32 to move away from the locking motor 33, thus confining the first and second locking rods 521 and 522 within their respective mating holes. This design ensures that the locking action is only performed when the locking rods are indeed fully inserted. The two locking parts 32 are driven synchronously by the same locking motor 33, which ensures the simultaneity of the locking action on both sides and the uniformity of the force. The connection between the feces bucket 30 and the locking part 52 is completed instantly and is firm and reliable.

[0069] In some embodiments, please refer to Figures 1 to 4 The main body 10 of the hospital bed is made of ferromagnetic material, and a permanent magnet is provided on the side of the bedpan 31 facing the leg plate 13 so that the bedpan 31 can be fixed to the side of the leg plate 13 near the ground.

[0070] In some embodiments, please refer to Figures 1 to 4 The bedside patient bed 100 also includes a control unit electrically connected to the power unit 43 and the feces container 30; the control unit is configured to perform the following control steps upon receiving excretion information: The control seat plate 12 moves a preset distance away from the back plate 11 to form a folding clearance.

[0071] The seat plate 12 is controlled to rotate away from the ground, while the seat plate 12 and the leg plate 13 are kept on the same plane.

[0072] The control power unit 43 drives the guide roller 42 to move along the bed to the connection position between the seat plate 12 and the leg plate 13.

[0073] Control the leg plate 13 to rotate toward the ground, so that the manure bucket 30 is fixed on the guide roller 42.

[0074] The control power unit 43 drives the guide roller 42 to move along the bed to the connection between the back panel 11 and the seat panel 12, so as to bring the bed sheet to the connection between the back panel 11 and the seat panel 12, and at the same time bring the manure bucket 30 directly below the discharge hole 120.

[0075] Control the seat 12 and backrest 11 to adjust the bed 100 of the bedridden patient to a sitting position.

[0076] With this configuration, by placing the seat 12 and leg rest 13 at a certain angle to the horizontal plane and setting the backrest 11 on the horizontal plane, most of the patient's weight is distributed on the backrest 11, thereby making it easier for the guide roller 42 to bring the sheet to the backrest 11.

[0077] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
