[0002] In clinical practice, many critically ill patients, such as those with heart failure, need to stay in bed due to their serious condition. These patients can often solve their urination and defecation problems by themselves, but they cannot get out of bed and need to solve them in bed. This is because getting out of bed may aggravate heart failure, leading to sudden death of the patient, which is not conducive to the patient's recovery, and may even aggravate the patient's condition.

[0003] In order to increase the function of defecation and urination, the nursing bed disclosed in the related art is provided with an opening on the bed board of the bed, and a bedpan is fixedly placed thereunder. This simple structure has many inconveniences in use. For example, since the bedpan is located at the bottom of the bed, a person is required to put the bedpan to the bottom of the bed, and the bedpan needs to be taken out and cleaned after use. This process requires the nursing staff to squat down and stretch their arms to put in or take out the bedpan, which is extremely inconvenient. Utility Model Content

[0069] The nursing bed with auxiliary defecation and urination function according to an embodiment of the utility model is described in detail below with reference to the accompanying drawings.

[0070] Reference Figures 1 to 6 As shown, the nursing bed with auxiliary defecation and urination function provided according to the embodiment of the utility model includes a bed frame 10, a bed board 20, a cover board, an ejection mechanism 30, a lifting mechanism 40 and a sliding mechanism 50.

[0071] Specifically, the bed frame 10 is generally a metal bed frame 10, which has high structural strength and is more reliable and durable to use. The bed board 20 is arranged on the bed frame 10, and a window H20 for defecation and urination is opened on the bed board 20. The bed board 20 can be a whole bed board 20 or multiple bed boards 20 for the patient to lie down.

[0072] The cover plate is adapted to the window H20 and covers the window H20. The cover plate can be made of the same material as the bed board 20. When the cover plate is covered on the window H20, the cover plate and the bed board 20 are located in the same plane. Preferably, the cover plate is arranged on the bed frame 10 and supported by the bed frame 10 to ensure that the cover plate has the same load-bearing capacity as the bed board 20.

[0073] The ejection mechanism 30 is provided on the bed frame 10 for the user to operate and lift the cover plate to facilitate the removal of the cover plate. When the cover plate needs to be removed to open the window H20, the ejection mechanism 30 can be used to conveniently lift the cover plate on the bed frame 10 and then remove the cover plate.

[0074] The lifting mechanism 40 is arranged on the bed frame 10 and below the bed board 20. The lifting mechanism 40 is mainly used to drive the bedpan to rise and fall, so that the bedpan rises and is close to the bottom surface of the bed board 20, ensuring that the bedpan can be close to the window H20 on the bed board 20.

[0075] The sliding mechanism 50 is provided on the lifting mechanism 40, and is used to be lifted and lowered vertically within a predetermined height range under the drive of the lifting mechanism 40. The sliding mechanism 50 is suitable for carrying a bedpan, and can drive the bedpan to move between a first position and a second position along the width direction of the bed frame 10. When the bedpan is located at the first position, the bedpan is located directly below the window H20, and when the bedpan is located at the second position, the bedpan is adjacent to one side of the bed frame 10 in the width direction.

[0076] That is to say, on the one hand, the sliding mechanism 50 is arranged on the lifting mechanism 40, and can be raised or lowered vertically under the drive of the lifting mechanism 40. On the other hand, the bedpan can be placed on the sliding mechanism 50, and the sliding mechanism 50 drives the bedpan to slide between the first position and the second position along the width direction of the bed frame 10, thereby realizing the movement of the bedpan to the bottom of the window H20 or to the side of the bed frame 10. When the bedpan is located directly below the bedpan, it is convenient for the patient to urinate and defecate. When the bedpan is located on the side of the bed frame 10, it is convenient to take out the bedpan and clean it. It can be understood that the bedpan is located on the sliding mechanism 50 and can be raised or lowered with the sliding mechanism 50.

[0077] The following briefly describes the use process of the nursing bed with auxiliary defecation and urination function of this embodiment.

[0078] First, the patient lies on the bed board 20, and when the patient needs to urinate or defecate, the caregiver can operate the ejection mechanism 30 to lift the cover plate, and then remove the cover plate. At this time, the window H20 can be opened.

[0079] Next, the sliding mechanism 50 is used to drive the bedpan from the second position to the first position, so that the bedpan moves to the bottom of the window H20. The lifting mechanism 40 is then used to drive the sliding mechanism 50 and the bedpan to rise, so that the bedpan is close to the bottom surface of the bed board 20. At this time, the bedpan can be close to the bed board 20 and remain directly below the window H20.

[0080] Further, in this state, the patient can urinate or defecate on the bed aligned with the window H20. After the urination or defecation is completed, the cover plate is re-covered. The lifting mechanism 40 can be used to drive the sliding mechanism 50 and the bedpan to descend to a certain height position.

[0081] Finally, the bedpan is driven to move to the second position by the sliding mechanism 50, so that the bedpan can be moved to one side of the bed frame 10. The caregiver cleans the bedpan after taking it out.

[0082] According to the nursing bed with auxiliary defecation function provided by the embodiment of the utility model, the lifting mechanism 40 can drive the sliding mechanism 50 and the bedpan to lift and lower, and the sliding mechanism 50 can drive the bedpan to slide between the first position and the second position. In use, the bedpan can be slid to the first position by the sliding mechanism 50, so that the bedpan is directly below the window H20, and then the lifting mechanism 40 is used to raise the bedpan so that the bedpan is close to the bed board 20, and after the ejection mechanism 30 lifts the cover plate, the cover plate can be removed and the window H20 can be opened, so that defecation can be achieved on the bed. After defecation and urination are completed, the lifting mechanism 40 lowers the bedpan, and then drives the bedpan to move to the second position, that is, the side of the bed, through the sliding mechanism 50, which is very convenient for cleaning the bedpan. The nursing bed can make the use process easier and simpler, and at the same time, it is also convenient to take out and clean the bedpan, which provides great convenience for bedridden patients.

[0083] In one embodiment of the present invention, the lifting mechanism includes an X-shaped lifting frame 401, a bracket 402 and a first driving mechanism 403. The X-shaped lifting frame 401 is an X-shaped pivot structure composed of two crossed pivot arms. The X-shaped lifting frame 401 can provide good stability and load-bearing capacity. The X-shaped lifting frame 401 is usually made of metal material and has high strength and durability.

[0084] The support is arranged on the X-shaped lifting frame 401, and the sliding mechanism 50 is arranged on the support 402. The support 402 is a component for placing the sliding mechanism 50 and the bedpan, and is installed on the top of the X-shaped lifting frame 401. The sliding mechanism 50 can enable the bedpan to move horizontally on the platform, for example, drive the bedpan to slide from a first position to a second position in the width direction of the bed frame 10, or slide from the second position back to the first position.

[0085] The first driving mechanism 403 is connected to the X-shaped lifting frame 401 to drive the X-shaped lifting frame 401 to move up and down, so that the bracket 402 moves up and down accordingly. The first driving mechanism 403 controls the movement of the X-shaped lifting frame 401 to move the bracket 402 up and down accordingly. In this way, the toilet bowl on the sliding mechanism 50 can be adjusted to different heights with the movement of the lifting mechanism.

[0086] In this embodiment, the design can realize the lifting and horizontal sliding of the bedpan. The control of the first driving mechanism 403 enables the lifting mechanism to be accurately adjusted to the required height, and the design of the sliding mechanism 50 enables the bedpan to be conveniently moved in the width direction of the bed frame 10, so that the automatic adjustment control of the bedpan position can be realized.

[0087] In one embodiment of the utility model, the first driving mechanism 403 includes a first screw rod 4031, a first nut 4032, a first driving motor 4034 and a bevel gear set 4033, the first screw rod 4031 is pivotally disposed at the bottom of the X-shaped lifting frame 401, the first screw rod 4031 is threadedly mounted on the first screw rod 4031 and is connected to a pivot arm of the X-shaped lifting frame 401, and the first driving motor is transmission-connected to the first screw rod 4031 via the bevel gear set 4033.

[0088] When the first driving motor 4034 is started, the power is transmitted to the first screw rod 4031 through the transmission of the bevel gear set 4033. The first screw rod 4031 starts to rotate, and the first nut 4032 moves on the first screw rod 4031 accordingly. Since the bracket 402 is connected to the first nut 4032, the bracket 402 will also move in the horizontal direction with the movement of the first nut 4032, thereby driving the two pivot arms of the X-shaped lifting frame 401 to rotate relative to each other, so that the entire X-shaped lifting frame 401 can be lifted and lowered.

[0089] In this embodiment, the first driving mechanism 403 utilizes the transmission mechanism of the first driving motor 4034 and the bevel gear set 4033 to drive the rotation of the first screw rod 4031, thereby realizing the lifting movement of the X-shaped lifting frame 401. This design has the characteristics of simple structure, high reliability and smooth lifting, which provides convenience and reliability for the use of the nursing bed.

[0090] In one embodiment of the utility model, the sliding mechanism 50 includes a sliding support plate 501 and a second driving mechanism 502. The sliding support plate 501 is slidably disposed on the support seat 402 along the width direction of the bed frame 10, and a placement opening suitable for positioning the bedpan is provided on the sliding support plate 501. The design of the placement opening allows the bedpan to be stably placed on the sliding support plate 501 and maintained at a desired position.

[0091] The second driving mechanism 502 is disposed on the bracket 402 and connected to the sliding support plate 501, and is used to drive the sliding support plate 501 to slide. The second driving mechanism 502 controls the sliding support plate 501 to move in the horizontal direction to adjust the position of the toilet bowl. When the second driving mechanism 502 is started, it can transmit power to the sliding support plate 501 to slide along the width direction of the bed frame 10, so that the toilet bowl can slide between the first position and the second position.

[0092] In this embodiment, the sliding mechanism 50 drives the sliding tray 501 to slide, so as to adjust the position of the bedpan in the width direction of the bed frame 10. The structure is simple, the position adjustment is reliable and stable, and the placement opening on the sliding tray 501 can ensure that the bedpan remains stable during the sliding process.

[0093] In one embodiment of the present invention, the bracket 402 includes a bottom plate 4021 and two side plates 4022, the two side plates 4022 are arranged on the bottom plate 4021 in a direction perpendicular to the length of the bed frame 10, and a storage space suitable for accommodating the bedpan is defined between the two side plates 4022 and the bottom plate 4021. That is, the two side plates 4022 are arranged on the bottom plate 4021 in a direction perpendicular to the length of the bed frame 10, forming a U-shaped structure. Such an arrangement forms a storage space between the two side plates 4022 and the bottom plate 4021 for accommodating the bedpan.

[0094] The inner wall of each side plate 4022 has a slide groove, and one side edge of the sliding support plate 501 is slidably matched with the slide groove of one side plate 4022, and the other side edge of the sliding support plate 501 is slidably matched with the slide groove of another side plate 4022. This design allows the sliding support plate 501 to slide along the slide groove of the side plate 4022, thereby adjusting the position of the toilet bowl.

[0095] In this embodiment, the sliding groove between the sliding support plate 501 and the side plate 4022 is used to slide and cooperate to ensure the smooth sliding and stable fixation of the sliding support plate 501. In addition, the U-shaped structure composed of the bottom plate 4021 and the two side plates 4022 is used to facilitate the placement of the bedpan and keep the bedpan stable and reliable.

[0096] In one embodiment of the utility model, the second driving mechanism 502 includes a second screw rod 5021, a second nut 5022 and a second driving motor 5023, the second screw rod 5021 is pivotally arranged at the bottom of the bracket 402, the bottom plate 4021 is provided with a guide groove extending along the width direction of the bed frame 10, the second nut 5022 is threadedly matched with the second screw rod 5021, and the second nut 5022 is provided with a connecting portion, the connecting portion is slidably matched with the guide groove, and the bottom of the sliding support plate 501 is provided with a fixing portion connected to the connecting portion.

[0097] When the second drive motor 5023 is started, power is transmitted to the second screw rod 5021 to rotate. The rotational motion of the second screw rod 5021 is transmitted to the second nut 5022 through threaded engagement, and the second nut 5022 is connected to the fixed portion at the bottom of the sliding support plate 501 through the connecting portion, so that the second nut 5022 can push the sliding support plate 501 to slide, thereby realizing the driving of the sliding support plate 501.

[0098] In this embodiment, the second driving mechanism 502 realizes the sliding drive of the sliding support plate 501. The threaded cooperation of the second screw rod 5021 and the second screw nut 5022 allows the rotational motion of the second driving motor 5023 to be converted into the linear sliding motion of the sliding support plate 501. The sliding cooperation of the connecting part and the guide groove ensures the smooth sliding of the sliding support plate 501. The design of the second driving mechanism 502 provides precise drive and control, so that the sliding support plate 501 can be accurately adjusted to the desired position.

[0099] In one embodiment of the present invention, the ejection mechanism 30 comprises a pivot rod 301 , an eccentric toggle member 302 and an operating handle 303 . The pivot rod 301 is pivotally disposed on the bed frame 10 around a horizontal axis. The horizontal axis extends along the width direction of the bed frame 10 .

[0100] The eccentric toggle member 302 is fixed to the inner end of the pivot rod 301 and is located below the cover plate. When the pivot rod 301 rotates around the horizontal axis, the eccentric toggle member 302 will also rotate. The operating handle 303 is fixed to the outer end of the pivot rod 301, and is used for the user to operate to rotate the pivot rod 301, so as to drive the eccentric toggle member 302 to lift the cover plate through the pivot rod 301. Through the operating handle 303, the user can rotate the pivot rod 301, thereby driving the eccentric toggle member 302 to rotate, and then lift the cover plate through the eccentric toggle member 302.

[0101] Through the design of this embodiment, the ejection mechanism 30 realizes the function of lifting the cover plate by driving the eccentric toggle member 302 through the pivot rod 301. The operating handle 303 provides a convenient operation mode, and the user can control the action of the ejection mechanism 30 by turning the operating handle 303. The rotational movement of the pivot rod 301 is transmitted to the cover plate through the eccentric toggle member 302, thereby realizing the lifting of the cover plate. This ejection mechanism 30 is simple and effective in design, has high reliability, provides convenient operation and control, and is used to realize the lifting function of the cover plate.

[0102] Preferably, the operating handle 303 rotates in opposite directions to the eccentric toggle member 302. For example, when the operating handle 303 is pressed downward and rotated, the eccentric toggle member 302 can rotate upward to lift the cover plate, so that the operation is more convenient and labor-saving.

[0103] Advantageously, the cover plate has a protrusion protruding outward in a horizontal direction, and the eccentric push piece 302 is located below the protrusion. In this way, the eccentric push piece 302 can be used to push up the protrusion, so that one side of the cover plate can be lifted. The user can remove the cover plate from the lifted side, which is more convenient to use.
