Description

Technical Field

[0001] This invention relates to the field of commode chair technology, specifically an automatically sealing bedside commode chair. Background Technology

[0002] A commode chair is an assistive device specifically designed for patients with limited mobility, especially those recovering from myocardial infarction. Due to their condition, these patients often require absolute bed rest in the early postoperative period and are unable to go to the toilet independently, relying instead on a commode chair at their bedside. The design of the commode chair prioritizes patient convenience and comfort, typically featuring a removable collection container or bag for easy bedside urination. This device not only avoids increased cardiac load due to movement but also effectively prevents accidents that may occur while traveling to the toilet. Furthermore, the use of a commode chair prevents waste from polluting the indoor environment and reduces the embarrassment caused by unpleasant odors. However, if waste is not disposed of promptly after use, the waste in the collection bag can easily become a source of contamination, leading to bacterial growth and odor spread. This not only affects indoor air quality but may also increase the risk of cross-infection. Therefore, timely disposal is crucial during use.

[0003] Existing commode chairs employ various sealing technologies to prevent the spread of contamination, with rapid heat sealing being a common solution. This technology uses a heating device to create a seal at the opening of the collection bag, effectively preventing leakage of excrement and the spread of odors. However, existing devices have significant limitations; they focus solely on the sealing action itself and employ a single-use sealing design. This means that after each use, the entire collection bag must be removed and a new one installed before the next use. While this single-use design ensures a good seal, it significantly increases the workload of caregivers, especially when patients have high bowel movement frequency, requiring repeated replacements. Summary of the Invention

[0010] Preferably, the second lifting assembly includes a support frame, a movable plate, a second motor, a second lead screw, and a second guide rod; The top and bottom ends of the support frame are fixedly connected to the bottom end of the back plate and the top of the base, respectively; the movable plate is slidably disposed in the support frame along the height direction; the second motor is fixedly disposed at the bottom of one side of the support frame; one end of the second lead screw is drivenly connected to the output shaft of the second motor, and the other end passes through one end of the movable plate and is rotatably connected to the top of the support frame; the second lead screw is threadedly engaged with the movable plate.

[0023] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of the invention, unless otherwise stated, "a plurality of" means two or more.

[0024] Example 1 like Figures 1-7 As shown, an embodiment of the present invention provides an automatically sealing bedside commode chair, including a commode chair body, a bag retrieval assembly, a sealing assembly, and a base 3.

[0025] like Figure 1 and Figure 2 The figures shown are schematic diagrams of the structure from two different perspectives. The base 3 has a waste storage tank 9 and an annular storage bag cavity surrounding the waste storage tank 9; the annular storage bag cavity contains a cylindrical bag 13 wound in a ring shape, and the top of the base 3 has an annular groove through which the cylindrical bag 13 passes.

[0026] like Figure 3 and Figure 4 These are schematic diagrams of the internal structure of the toilet seat from two different perspectives, excluding the top structure. The bag retrieval assembly is located inside the toilet seat body and includes a first lifting assembly and a heating ring 18. The first lifting assembly is located on the wall of the toilet seat body. The heating ring 18 is driven to rise and fall by the first lifting assembly, descending to the top of the base 3 to melt and absorb the top of the tubular bag 13, then rising to retrieve the tubular bag 13.

[0027] like Figure 5 and Figure 6 These are schematic diagrams of the toilet seat removal structure from two different perspectives. The sealing assembly includes a second lifting assembly, a synchronous drive assembly, and two hot cutting blades 12; the back of the toilet seat body has an opening; the second lifting assembly is located on the back of the toilet seat body and drives the synchronous drive assembly to lift and lower; the two hot cutting blades 12 are mounted on the synchronous drive assembly and are synchronously driven by the synchronous drive assembly to move relative to or opposite to each other. Furthermore, as... Figure 7 As shown, Figure 7 This is a schematic diagram of the hot cutting blade 12. The length of the hot cutting blade 12 is greater than the diameter of the tubular bag 13, and from top to bottom, it has a positioning rib 12-1 for clamping and a welding and bonding rib 12-2 for energizing and bonding the tubular bag 13.

[0028] The bedside commode chair proposed in this invention deeply integrates the sealing action with the usage process. During preparation, the bag-retrieving component, via the first lifting component, drives the heating ring 18 to electrothermally melt and adsorb the top of the tubular bag 13, pulling it to form a preliminary collection bag shape. Further, the sealing component, via the second lifting component, drives two hot-cutting blades 12 to descend to a designated position. Through a synchronous drive component, the hot-cutting blades 12 move relative to each other, and the fusion-bonding ribs 12-2 on the two hot-cutting blades 12 are electrically heated, completing the melting and sealing of the lower end of the tubular bag 13 in a very short time. The adhesive forms a sealed collection bag at the bottom. After the patient finishes urinating, the sealing assembly drives two hot-cutting blades 12 to rise to a designated position via the second lifting assembly. The synchronous drive assembly moves the hot-cutting blades 12 relative to each other. The positioning ribs 12-1 on the hot-cutting blades 12 first precisely clamp the neck of the bag 13 filled with excrement. Then, the adhesive ribs 12-2 are heated by electricity, completing the melting and bonding of the bag 13 in a very short time. The remaining bag is pulled away from the heating ring 18 by the clamping force provided by the positioning ribs 12-1. This action seals the contaminants the moment the urination is completed, fundamentally cutting off the path of odor diffusion and bacterial growth, avoiding indoor environmental pollution and patient embarrassment caused by the failure to clean the traditional commode chair in time. The signal for automatically triggering the sealing and preparing the next collection bag is provided by the toilet seat 1. Multiple pressure sensors are set around the bottom of the toilet seat 1. The controller (which can be a microcontroller or other controllers, not limited here) determines whether urination is complete based on the sensor signals, and then controls the various components to perform actions.

[0029] Secondly, this bedside commode chair solves the problem of frequent bag replacement required by traditional single-seal structures through its annular bag chamber design. Specifically, a circularly wound cylindrical bag 13 is pre-installed in the base 3. After the sealing assembly completes the fusion sealing of the used cylindrical bag 13, the bag retrieval assembly starts working again. This series of actions achieves automatic replenishment and placement of the collection bag, eliminating the need for manual rearrangement by caregivers and greatly facilitating high-frequency use scenarios.

[0030] The entire process of sealing and unfolding the new bag in this invention's bedside commode chair is completed by a mechanical structure, requiring no human assistance. The synchronous drive assembly ensures the precision and synchronization of the movement of the two hot-cutting blades 12 during clamping and melting, guaranteeing the reliability of each seal; the cooperation between the heating ring 18 and the first lifting assembly ensures the precise positioning and unfolding of the new tubular bag 13. After use, the patient only needs to stand up normally, and the device automatically completes the sealing of contaminated materials and the preparation of a new collection bag, significantly reducing the dependence of post-myocardial infarction patients on nursing staff, while also alleviating the workload and psychological burden on nursing staff when handling excrement.

[0031] Furthermore, the base 3 integrates both a waste storage trough 9 and an annular storage bag cavity. The waste storage trough 9 is used to temporarily store sealed excrement bags, while the annular storage bag cavity surrounds the waste storage trough. This nested design achieves both storage and feeding functions within a limited space, resulting in a compact and reasonable structure. The opening on the back of the toilet seat body facilitates the installation and maintenance of the sealing assembly, ensuring that the entire device meets functional requirements while maintaining the portability and aesthetics expected of a bedside toilet seat.

[0032] Furthermore, the hot cutting blade 12 of the present invention has a built-in thermoelectric wire in the fusion bonding rib 12-2; the end of the hot cutting blade 12 is an arc-shaped structure made of flexible metal, and the length of the straight section of the hot cutting blade 12 is greater than the diameter of the tube bag 13, so as to achieve complete wrapping of the tube bag 13.

[0033] Among them, the heating ring 18 and the fused adhesive rib 12-2 both rely on built-in thermoelectric wires to achieve the thermal effect, but because they play completely different roles in the automatic bag taking and automatic sealing process, they have significant differences and specific requirements in structural design, temperature control and mode of action.

[0034] Firstly, in terms of function and heating method, the heating ring 18 is primarily responsible for "fusion and lifting." Its core task is to adsorb and fix the top of the new cylindrical bag inside the annular storage bag cavity onto the ring body for upward pulling and unfolding. This requires the heating of the heating ring 18 to be uniform and gentle. Therefore, its built-in thermoelectric wires typically employ a low power density design, evenly distributed around the entire ring body to ensure a consistent ring wall temperature and avoid localized overheating that could burn through the cylindrical bag or cause a weak fusion. When the heating ring 18 descends into the annular groove of the base, its annular contact surface needs to achieve a large-area, light-pressure contact with the cylindrical bag material. Adsorption can be completed by only slightly melting the surface of the cylindrical bag to create adhesion, rather than completely melting it off.

[0035] The fusion-bonding rib 12-2 is responsible for "clamping and sealing," requiring the simultaneous completion of three processes: clamping the tube bag 13, fusing and separating, and bonding and sealing. This places extremely high demands on the coordination of temperature and mechanical action. Its built-in thermoelectric wire typically employs a high-power-density design, concentrated on the cutting edge or specific working surface of the fusion-bonding rib 12-2 to generate high temperatures instantaneously. Meanwhile, the hot-cutting blade 12 is designed with a double-layer structure from top to bottom: the upper positioning rib 12-1 mainly serves a mechanical clamping function, usually without heating or only providing auxiliary heating, used to fix the position of the tube bag 13 to prevent displacement; the lower fusion-bonding rib 12-2 concentrates the heat, requiring the melting and pressing of multiple layers of tube bag 13 material together at the moment of clamping, achieving an airtight seal while separating the upper and lower sections of the tube bag 13.

[0036] Regarding material and structural requirements, the heating ring 18, due to its repeated lifting and lowering and contact with the tubular bag 13, must have an anti-stick coating on its surface, and the ring itself must have sufficient rigidity to maintain its circular outline and prevent deformation that could lead to lifting failure. The fusion bonding rib 12-2 requires a certain degree of flatness in the cutting edge. When the two hot cutting blades 12 are closed under the synchronous drive assembly, the fusion bonding rib 12-2 must fit tightly to ensure that the width of the weld line is consistent and the seal is reliable, avoiding incomplete sealing or poor welding.

[0037] In terms of control logic, the heating ring 18 usually adopts timed temperature control, and can be de-energized and cooled after reaching the preset temperature and completing adsorption; while the fused adhesive rib 12-2 requires precise pulse heating control, which releases high temperature the moment it is clamped in place, and quickly maintains pressure to cool and solidify after melting, so as to form a strong sealing line.

[0038] To facilitate the replenishment of the tubular bag 13, an annular cover plate 14 is provided at the top of the annular storage bag cavity; the outer circumferential edge of the annular cover plate 14 is inserted and fixed to the cavity wall of the annular storage bag cavity; the top of the annular cover plate 14 and the base 3 are reserved with grooves in the shape of a hot cutting blade 12 to avoid the bag-removing action of the heating ring 18. In addition, a groove communicating with the waste storage tank 9 is opened on the back of the base 3; a collection drawer 17 is slidably fitted in the tank to facilitate the rapid collection, accumulation and sealing of excrement.

[0039] The following is one preferred embodiment of the present invention. Both the lifting assembly and the moving assembly adopt a motor lead screw transmission structure to ensure the accuracy of movement. Specifically: like Figure 1 As shown, the toilet chair body includes a seat 2, a backrest 4, a toilet seat ring 1, and two support plates 6; the back of the seat 2 has an opening; the two support plates 6 are set on both sides of the top of the seat 2; the lower end of the backrest 4 is fixedly connected to the two support plates 6; each support plate 6 has an armrest 7 at its top; the rear end of the toilet seat ring 1 is hinged to the rear edge of the seat 2; and multiple pressure sensors are arranged circumferentially at the bottom of the toilet seat ring 1.

[0041] Specifically, such as Figure 5 and Figure 6 As shown, the second lifting assembly includes a support frame 5, a movable plate 15, a second motor, a second lead screw 8, and a second guide rod 11. The top and bottom ends of the support frame 5 are fixedly connected to the lower end of the back plate 4 and the top of the base 3, respectively. The movable plate 15 is slidably disposed within the support frame 5 along the height direction. The second motor is fixedly disposed at the bottom of one side of the support frame 5. One end of the second lead screw 8 is drivenly connected to the output shaft of the second motor, and the other end passes through one end of the movable plate 15 and is rotatably connected to the top of the support frame 5. The second lead screw 8 is threadedly engaged with the movable plate 15. The second guide rod 11 passes through the other end of the movable plate 15 and is slidably engaged with the movable plate 15. The two ends of the second guide rod 11 are rotatably connected to the top and bottom of the support frame 5, respectively.

[0042] Furthermore, the synchronous drive assembly includes a third motor and a bidirectional lead screw 16; the bidirectional lead screw 16 is welded together from two lead screws with opposite threads; the moving plate 15 has a sliding groove along its transverse length; the third motor is fixedly mounted at one end of the sliding groove; the starting ends of the two hot cutting blades 12 are slidably mounted in the sliding groove; both ends of the bidirectional lead screw 16 pass through the two hot cutting blades 12 respectively, and the two lead screws with opposite threads are threadedly engaged with the two hot cutting blades 12 respectively; one end of the bidirectional lead screw 16 is drivenly connected to the output shaft of the third motor, and the other end is rotatably connected to the other end of the sliding groove.

[0043] All of the above motors are controlled by microcomputer-based controllers. The preset control logic can be executed. The transmission of control signals and sensor signals can be wireless or wired, which are all control methods that can be achieved by existing technology, and will not be elaborated here.

[0044] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
