Description

Technical Field

[0001] This invention specifically relates to the field of medical bed technology, and more specifically to a medical bed that facilitates the handling of urination and defecation for bedridden patients. Background Technology

[0002] Medical nursing beds are essential equipment in hospitals for caring for bedridden patients. Existing nursing beds consist of a headboard and a bed frame, with the bed frame made up of several relatively flexible bed boards. These boards can be bent at a certain angle to accommodate changes in the patient's lying position during daily care. The most challenging aspect is managing the patient's bowel and bladder functions. Patients on these beds require assistance to urinate or defecate, and the room is often filled with unpleasant odors afterward. This not only creates discomfort for the patient but also adds inconvenience for family members and medical staff.

[0003] The invention patent with publication number CN111803297A discloses a multifunctional medical bed that facilitates patients' urination and defecation. It includes a toilet component, a movable bed board, a lift mechanism, and a medical bed. The toilet component and the lift mechanism are placed in the medical bed. The upper board of the toilet component is hinged to the movable bed board, and the movable bed board is hinged to the lift mechanism. The angle between the toilet component and the movable bed board is adjusted by the lift mechanism so that the toilet component can be transformed into a seat shape, and the patient can sit on the toilet component to urinate and defecate.

[0004] Although the aforementioned invention patent can fold a horizontal hospital bed into a seat position to help patients with limited mobility to relieve themselves in bed, the device needs to be adjusted to a seat position during use. Paralyzed or orthopedic patients have limited mobility and cannot adjust their body posture during the recovery period, so this type of medical bed still cannot handle patients' urination and defecation. Summary of the Invention

[0005] The purpose of this invention is to provide a medical bed that facilitates the handling of urination and defecation for bedridden patients, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

The bed frame includes a mattress, a support frame for the mattress, and a rotatable, movable pad disposed within the mattress. The mattress has a drainage opening for accommodating the movable pad. For ease of use, the drainage opening is located in the middle of the bed frame, allowing the patient to quickly align their hips with the opening without moving their body, thus facilitating urination and defecation. The collection box is rotatably mounted beneath the bed frame, positioned below the drainage opening, and has a horizontal design. The bed has an initial state and a tilted rotating state. When the collection box rotates from the initial state to the rotating state, it can collect the patient's excrement. The bed is equipped with a rotation adjustment mechanism that drives the movable pad to rotate and open, and a drive mechanism that controls the rotation adjustment mechanism and the collection box to rotate in sequence. When the patient needs to urinate or defecate, the drive mechanism first controls the rotation adjustment mechanism to rotate, which in turn controls the movable pad to rotate and open, so that the excretion opening is exposed. The drive mechanism then controls the collection box to rotate from the horizontal state to the rotating state, so that the collection box passes through the excretion opening and is aligned with the patient's crotch, thereby collecting urine and feces.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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.

[0035] Please see Figures 1-10In this embodiment of the invention, a medical bed for facilitating the handling of urine and feces in bedridden patients includes a bed frame 10 and a collection box 20 disposed below the bed frame 10. The bed frame 10 includes a mattress 11, a support frame 12 supporting the mattress 11, and a movable pad 14 disposed within the mattress 11 and capable of being rotated and opened. The mattress 11 has a drain opening for accommodating the movable pad 14. For the convenience of the patient, the drain opening is located in the middle area of ​​the bed frame 10, allowing the patient to quickly align their hips with the drain opening without moving their body, thus facilitating the patient's urination and defecation. Furthermore, the collection box 20 is rotatably mounted below the bed frame 10. In this embodiment, the collection box 20 is located below the drain opening. The collection box 20 has a horizontal initial state and an inclined rotating state. When the collection box 20 rotates from the initial state to the rotating state, it can collect the patient's excrement. The bed body 10 is equipped with a rotation adjustment mechanism 40 that drives the movable pad 14 to rotate and open, and a drive mechanism 30 that controls the rotation adjustment mechanism 40 and the collection box 20 to rotate in sequence. When the patient needs to defecate, the drive mechanism 30 first controls the rotation adjustment mechanism 40 to rotate, which in turn controls the movable pad 14 to rotate and open so that the excretion opening is exposed. The drive mechanism 30 then controls the collection box 20 to rotate from the horizontal state to the rotating state so that the collection box 20 passes through the excretion opening and is aligned with the patient's crotch, thereby collecting urine and feces.

[0036] Please see Figures 3-6 In this embodiment of the invention, the rotation adjustment mechanism 40 includes a mounting base 41, a connecting rod 42, and a drive rod 47. The mounting base 41 is fixedly installed on the bottom of the movable pad 14. One end of the connecting rod 42 is rotatably connected to the movable pad 14, and the other end of the connecting rod 42 is rotatably connected to the bed frame 10. It should be noted that the installation position of the other end of the connecting rod 42 is specifically in the inner wall of the discharge port. One end of the drive rod 47 is rotatably connected to the movable pad 14, and the other end of the drive rod 47 is rotatably installed on the bracket 12 via a drive shaft. Additionally, a fixing pin 44 is provided on the bracket 12. The fixing pin 44 is connected to the mounting base 41 via a connecting spring 43. It is understood that the movable pad 14 also has a horizontal state and a tilted state after rotation. In this embodiment, the tilted state is preferably a vertical state. When the movable pad 14 is in a horizontal state, the movable pad 14 covers the drain port to form a flat bed surface, which is convenient for the patient to lie down. When the movable pad 14 is in a tilted state, the drain port is open so that the collection box 20 can enter and receive the patient's urine and feces.

[0037] Furthermore, a first gear 45 is fixedly mounted on the drive shaft, and a second gear 46 is rotatably mounted on the inner side of the bracket 12. The second gear 46 meshes with the first gear 45. When the second gear 46 rotates, it drives the first gear 45 to rotate. When the second gear 46 rotates clockwise, the first gear 45 rotates counterclockwise, causing the drive shaft and drive rod 47 to rotate counterclockwise. The drive rod 47, with the cooperation of the connecting rod 42, expands the movable pad 14, such as... Figures 3-5 It is worth noting that when the movable pad 14 is opened, the connecting spring 43 is in a retracted state, thereby positioning the opened position of the movable pad 14 so that the movable pad 14 remains in an open state; when the movable pad 14 is retracted, the connecting spring 43 is also in a retracted state to prevent the movable pad 14 from falling off the drain port at will.

[0038] Please refer to it again. Figure 2 The bottom of the bracket 12 is provided with a side plate 15. The drive mechanism 30 includes an adjusting screw 32 rotatably mounted on the side plate 15 and a sliding seat 31 slidably mounted on the side plate 15. The adjusting screw 32 is threadedly connected to the sliding seat 31. An upper rack 311 is mounted on the upper side of the sliding seat 31. The upper rack 311 cooperates with the second gear 46. When the adjusting screw 32 rotates, it drives the sliding seat 31 to slide along the side plate 15. When the sliding seat 31 approaches the second gear 46, the upper rack 311 contacts and meshes with the second gear 46, causing the second gear 46 to rotate clockwise.

[0039] like Figure 7 As shown, in this embodiment of the invention, a frame 26 is provided on the outside of the collection box 20. The frame 26 is rotatably mounted on the bracket 12 via a connecting shaft. A third gear 261 is fixedly mounted on the connecting shaft. A lower rack 312 is mounted on the lower side of the sliding seat 31. The lower rack 312 cooperates with the third gear 261. When the sliding seat 31 approaches the third gear 261, the lower rack 312 contacts and meshes with the third gear 261, driving the third gear 261 to rotate counterclockwise.

[0040] To enable the drive mechanism 30 to sequentially control the rotation adjustment mechanism 40 and the collection box 20, the upper rack 311 is positioned on the front section of the upper side of the sliding seat 31, and the lower rack 312 is positioned on the rear section of the lower side of the sliding seat 31. The sliding seat 31 slides under the control of the adjusting screw 32. First, the upper rack 311 contacts the second gear 46, driving the movable pad 14 to rotate and open to expose the discharge port. Then, the lower rack 312 contacts the third gear 261, driving the collection box 20 to rotate and pass through the discharge port. Figure 6 As shown.

[0041] It should be noted that, in order to ensure that the upper rack 311 and the lower rack 312 can mesh with the second gear 46 and the third gear 261 respectively, the second gear 46 is located on the upper side of the sliding seat 31, and the third gear 261 is located on the lower side of the sliding seat 31. In addition, in order to improve the stability of the drive mechanism 30, two adjusting screws 32 are symmetrically arranged on the front and rear sides of the bed 10, and a synchronous pulley is installed at the end of each adjusting screw 32. The two synchronous pulleys are connected by a synchronous belt 33. Correspondingly, there are two sliding seats 31, two second gears 46, and two third gears 261.

[0042] Furthermore, in this embodiment, a drive motor is installed on the outer side of the side plate 15. The output end of the drive motor is connected to the adjusting screw 32 via a gearbox to control the rotation of the adjusting screw 32. To facilitate patient use, a button (not shown in the figure) for controlling the drive motor is provided on the bed 10. The button is electrically connected to the drive motor. After the patient manually presses the button, the drive motor works and controls the adjusting screw 32 to rotate, thereby opening the drain port.

[0043] Please refer to it again. Figure 7 The collection box 20 includes a housing 21, a receiving tube 22 slidably installed inside the housing 21, and a sliding control mechanism for controlling the sliding of the receiving tube 22. The receiving tube 22 has an arc-shaped structure. One end of the receiving tube 22 is connected to a receiving head 23 for receiving the patient's urine and feces, and the other end of the receiving tube 22 is connected to an excretion tube 25 for excreting the patient's urine and feces. After the collection tube 20 passes through the excretion opening, the sliding control mechanism controls the receiving tube 22 to slide so that the receiving head 23 is aligned with the patient's crotch to receive the patient's urine and feces. In order to make the receiving head 23 fit tightly against the patient's crotch, the receiving head 23 is connected to the receiving tube 22 through a retractable connecting tube 24. In this embodiment, the connecting tube 24 is a corrugated pipe. The patient's urine and feces are discharged from the collection box 20 after passing through the receiving head 23, the connecting tube 24, the receiving tube 22, and the excretion tube 25 in sequence, so as to achieve effective, fast and convenient treatment of the patient's excrement.

[0044] Furthermore, in this embodiment of the invention, the sliding control mechanism includes a driving gear 213 and a driven gear 212 rotatably mounted inside the housing 21. The driving gear 213 and the driven gear 212 mesh, and the driven gear 212 is provided with a disc protrusion. The disc protrusion is connected to the receiving tube 22 through a connecting arm 214. The driving gear 213 controls the driven gear 212 to rotate, thereby driving the receiving tube 22 to rotate through the connecting arm 214. In addition, a rotary motor is also provided on the outside of the housing 21. The output end of the rotary motor is connected to the driving gear 213 to control the rotation of the driving gear 213. Similarly, a button for controlling the rotary motor is provided on the bed 10 to facilitate the patient's operation.

[0045] Please see Figure 8 and Figure 9 The receiving tube 22 has a sealing plate 222 inside. One end of the sealing plate 222 is rotatably mounted on the receiving tube 22 via a rotating shaft, and the other end of the sealing plate 222 is provided with a sealing groove. The inner wall of the receiving tube 22 is provided with a sealing strip 223 corresponding to the sealing groove. When the receiving tube 22 extends out of the collection box 20, the sealing plate 222 opens to allow the patient's excrement to pass through the receiving tube 22. When the receiving tube 22 is retracted into the collection box 20, the sealing plate 222 closes to isolate the odor inside the receiving tube 22 and prevent the odor of the excrement from leaking out.

[0046] Furthermore, a connecting gear 221 is provided on the outer side of the receiving tube 22. The connecting gear 221 is fixedly connected to the end of the rotating shaft. An arc-shaped rack 211 is fixedly installed on the inner wall of the housing 21. The arc-shaped rack 211 meshes with the connecting gear 221. When the receiving tube 22 extends out of the collecting box 22, the connecting gear 221 rotates counterclockwise under the action of the arc-shaped rack 211, thereby driving the sealing plate 222 to rotate counterclockwise and open. When the receiving tube 22 is retracted into the collecting box 22, the connecting gear 221 rotates clockwise under the action of the arc-shaped rack 211, thereby driving the sealing plate 222 to rotate clockwise and close.

[0047] Furthermore, the receiving pipe 22 is also provided with an outlet 224 for connecting to the discharge pipe 25 so as to discharge the excrement.

[0048] Please see Figure 10 In this embodiment of the invention, the receiving head 23 is adapted to the shape of the patient's hip. Two arc-shaped grooves 231 are symmetrically opened on the left and right sides of the bottom of the receiving head 23. An excretion groove 232 is opened in the middle of the bottom of the receiving head 23. A protective pad 233 is provided on the upper part of the receiving head 23. An elastic strip 234 is provided at the bottom of the protective pad 233. The receiving head 23 is made of elastic material. In this embodiment, rubber is preferred to improve the patient's comfort.

[0049] In addition, a cleaning and drying mechanism can be installed at the bottom of the receiving head 23 to clean the patient's groin area and keep it clean. The cleaning and drying mechanism can use existing technologies, such as the cleaning nozzle and hot air drying head in a smart toilet.

[0050] Furthermore, in this embodiment of the invention, the bottom of the bed 10 is provided with a base 16 for support, and casters are provided at the four corners of the bottom of the base 16. In addition, guard plates 13 are provided on the front and rear sides of the bed 10.

[0051] In summary, this invention provides a drainage port on the bed frame of a medical bed, with a movable pad that can be opened within the drainage port. It also includes a rotation adjustment mechanism to drive the movable pad to open, and a drive mechanism to sequentially control the rotation of the rotation adjustment mechanism and the collection box. When a patient needs to urinate or defecate, the drive mechanism first controls the rotation adjustment mechanism to rotate, which in turn controls the movable pad to open, exposing the drainage port. The drive mechanism then controls the collection box to rotate from a horizontal position to a rotating position, allowing the collection box to pass through the drainage port and be aligned with the patient's groin. This not only allows for quick and accurate collection of the patient's urine and feces but is also convenient to operate and use, and can provide privacy by shielding the patient during defecation.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
