Description

Technical Field

[0001] The present invention relates to the field of medical equipment, in particular to a mobile toilet for use in wards. Background Art

[0002] At present, some patients hospitalized in hospitals and patients with mobility problems recuperating at home often need to urinate and defecate on the spot in the ward or bedroom with the help of nursing staff. The most commonly used convenient appliance is a combination of a seat with a hole in the middle and a bedpan.

[0003] When the patient needs to go to the bathroom, the nurse will first help the patient squat on the chair, and the patient's urine and feces will be directly discharged into the bedpan under the chair; after going to the bathroom, the nurse will help the patient get off the chair, then take out the bedpan under the chair and go to the bathroom to clean and flush it.

[0004] Due to the open structure of the bedpan, the patient will spread the unpleasant smell of excrement to the surrounding space when defecating, which directly causes discomfort to others in terms of smell, especially when sharing a ward with others, more people will be involved; when cleaning and flushing the bedpan, the nurse has to hold the bedpan and push it directly, which causes visual discomfort to the nurse.

[0005] Therefore, it is urgent to solve the problem of not only facilitating patients' use of the toilet, but also monitoring their health, reducing the spread of odor and improving their privacy. Summary of the Invention

[0006] In order to solve the problem that critically ill patients cannot go to the bathroom when their vital signs are continuously monitored, and at the same time ensure that patients have a suitable environment for use under any circumstances and protect their privacy, this application provides a mobile toilet for use in wards.

[0007] The mobile toilet provided in this application adopts the following technical solution:

[0008] A mobile toilet for use in a ward comprises a movable toilet body, an exhaust system and a collector; wherein the toilet body comprises a seat ring box, a back plate and a support column fixed to each other; wherein the back plate is arranged on the top end surface of the seat ring box; the support column is fixed to the bottom end surface of the seat ring box; the seat ring box is hollow and has an opening on the top of the seat ring box; the exhaust system cover is arranged on the outside of the toilet body, the exhaust system comprises a pressure sensor and an exhaust assembly arranged on the top of the seat ring box, the exhaust assembly is used to extract air around the toilet body and transport it to a set position; when the pressure sensor detects pressure at both the first time and the second time, the exhaust assembly runs for the first set time, and the interval between the first time and the second time is the second set time; the collector is detachably connected to the seat ring box, and the collector is at least partially located in the inner cavity of the seat ring box opposite to the opening, and is used to collect excrement passing through the opening.

[0009] By adopting the above technical solution, a movable toilet is used, and the seat and backboard are used to provide support for patients during toileting. The patient's excrement is collected by a collector arranged inside the seat for unified treatment. While its function is the same as that of a traditional toilet, it is convenient for medical staff to move and deploy quickly in an emergency.

[0010] When the patient sits on the sitting box, the pressure sensor can detect the pressure. At this time, the exhaust component will not start immediately, reducing the accidental activation of the exhaust component; and after the patient sits on the sitting box, the odor will not be generated immediately, which can reduce unnecessary energy consumption.

[0011] When the patient sits on the toilet seat for longer than the second set time, the exhaust assembly begins to operate, extracting odors from the toilet seat. When the patient stands up after using the toilet, the exhaust assembly continues to operate for a period not exceeding the first set time, until all odors from the toilet seat are largely extracted. It then stops automatically, facilitating use while reducing the spread of odors within the ward.

[0012] At the same time, the exhaust system covered on the outside of the toilet body is used to ensure air circulation and freshness, while also protecting the patient's privacy. When the patient needs to defecate, the call center staff can easily transfer the patient from his bed to the mobile toilet, while also maintaining continuous monitoring of the patient's vital signs, providing a convenient, safe and hygienic toilet solution for people with limited mobility such as critically ill patients. Nurses do not need to frequently assist patients to go to and from the toilet, saving physical energy and time, and ensuring that the patient's needs are effectively met.

[0013] Optionally, two sets of armrests are provided on the seat plate, at least one armrest is provided with a pager, the two sets of armrests are respectively provided on both sides of the opening, a first rotating shaft is provided on the seat plate, the bottom end of the armrest is rotatably connected to the seat plate through the first rotating shaft so as to rotate away from the opening, and a locking assembly is provided on the seat plate to keep the armrest at a certain angle.

[0014] By adopting the above technical solution, the armrest with a rotating arrangement can be rotated to a certain angle when the patient needs to move, thereby reducing the height of the patient during movement, reducing the risk of movement, and avoiding the safety hazards of patients who are bedridden or have limited mobility falling due to lack of physical strength, dizziness or limb weakness. At the same time, the locking component can be used to keep the armrest at a certain angle, thereby reducing the complexity of operations for medical staff during the patient's movement.

[0015] Optionally, the locking assembly includes a locking gear and a locking rack that mesh with each other, the locking gear is coaxially fixed to the first rotating shaft, one end of the locking rack is provided with a second rotating shaft and is connected to the seat plate for rotation, and the other end of the locking rack is provided with an operating handle extending out of the seat plate to control the locking gear and the locking rack to lock or separate, an elastic member is provided on the first rotating shaft to automatically reset the armrest, and the first rotating shaft adopts a damping shaft.

[0016] By adopting the above technical solution, the armrest can be locked more stably by utilizing the mutually meshing locking gear and locking rack. The armrest can automatically rotate back to its initial position by utilizing the elastic member during the process of separation of the locking rack and the locking gear, thereby facilitating the resetting of the armrest. The first rotating shaft adopts a damping shaft, which can reduce the kinetic energy of the armrest during rotation, thereby making the resetting process of the armrest smoother, reducing the possibility of injury to the patient due to the excessive rotation speed of the armrest, and improving practical safety.

[0017] Optionally, the armrest includes a support frame rotatably connected to the seat plate, and a first support plate and a second support plate are provided on the support frame. The first support plate is fixedly connected to the support frame, and the second support plate is slidably connected to the first support plate to increase the height of the armrest.

[0018] By adopting the above technical solution, the first support plate and the second support plate that are slidingly arranged can extend the overall length of the armrest. During use, the second support plate can be extended and placed next to the patient's bed. At the same time, the first support plate and the second support plate can be used to support the patient during transfer, so that the patient can be smoothly transferred from the bed to the toilet body through the first support plate and the second support plate, reducing the medical staff's handling of the patient and making the transfer of the patient more convenient.

[0019] Optionally, a stabilizing assembly is provided at the bottom of the seat plate, which includes a retractable connecting rod and a clamping ring. The clamping ring is hinged at the end of the connecting rod, and a clamping interface is provided on the side wall of the clamping ring to facilitate the clamping ring to be placed on the bed.

[0020] By adopting the above technical solution, during the patient transfer process, the connecting rod is extended, and the clamping ring is clamped on the leg or beam of the patient's bed using the clamping interface on the clamping ring. Through the rotatable clamping ring and the clamping interface opened laterally, the clamping ring can be connected or separated between the side and the bed, and good axial limitation can be obtained, thereby improving the connection stability between the clamping ring and the bed.

The flange on the top surface of the collection box can be used to tie the bag opening of the collection bag to the flange to keep the bag opening open. At the same time, the bag opening of the collection bag can be opened and closed in time using the closing component, which is convenient for quick cleaning and disinfection. At the same time, the closing component can reduce the odor and leakage of excrement overflow, reducing the risk of cross-infection.

[0023] Optionally, the closing assembly includes a plurality of fan-shaped sealing plates, which are slidably connected to the collection box along the radial direction of the opening, and a drive ring is rotatably connected to the outer periphery of the opening, and a spiral drive groove is provided on the drive ring. A slider is provided on the sealing plate, and the slider is located in the drive groove. A telescopic push-pull device is provided in the collection box to drive the drive groove to rotate.

[0024] By adopting the above-mentioned technical solution, multiple fan-shaped sealing plates and driving rings are used to drive the sealing plates at the same time, and the edges of the sealing plates are used to squeeze the collection bag to achieve the effect of sealing the collection bag. The spiral driving groove makes the driving ring of the sealing plate smoother, reducing the risk of the sealing plate damaging the collection bag.

[0025] Optionally, a heater is embedded in the seat plate.

[0026] By adopting the above technical solution, the seat plate can be heated to a certain temperature using a heater, thereby improving the patient's comfort during use, reducing the patient's psychological pressure during the recovery process, and enhancing the patient's confidence in self-care.

[0027] Optionally, a flexible filler is provided on the front of the back panel, the back panel is hollow, a deodorizing material is placed inside the back panel, and ventilation holes are provided on the side walls of the back panel.

[0030] By adopting the above technical solution, the exhaust system can be used to exchange the air inside and outside the curtain. Driven by the aerodynamic device, the air outside the curtain enters the curtain through the ventilation holes on the hollow exhaust bracket, and the ventilation inside the curtain is discharged outside the curtain through the aerodynamic device, which can maintain the air flow inside the curtain and improve the air quality in the mobile toilet.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. Use a movable toilet, with the seat and backboard providing support for patients during toileting. Use a collector inside the seat to collect the patient's excrement for unified treatment. While its function is the same as that of a traditional toilet, it is convenient for medical staff to move and deploy quickly in an emergency. At the same time, the exhaust system covered on the outside of the toilet body ensures air circulation and freshness, while also protecting the patient's privacy. When the patient needs to defecate, the call center staff can easily transfer the patient from his bed to the mobile toilet, and at the same time maintain continuous monitoring of the patient's vital signs, providing a convenient, safe and hygienic toilet solution for people with limited mobility such as critically ill patients. Nursing staff do not need to frequently assist patients to and from the toilet, saving physical energy and time, and ensuring that the patient's needs are effectively addressed.

[0033] 2. The armrest can be locked more stably by using the locking gear and locking rack that mesh with each other. The armrest can automatically return to its original position by using the elastic member during the separation of the locking rack and the locking gear, making it easier to reset the armrest. The first rotating shaft adopts a damping shaft, which can reduce the kinetic energy of the armrest during rotation, thereby making the armrest reset process smoother, reducing the risk of injury to the patient due to the excessive rotation speed of the armrest, and improving practical safety.

[0034] 3. The patient's excrement can be collected using the collection box and the collection bag.

[0048] The present application will be further described in detail below through the accompanying drawings and examples, through which the features and advantages of the present application will become more clear and distinct.

[0049] The word "exemplary" is used exclusively herein to mean "serving as an example, example, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0050] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0051] The following is combined with Figure 1-7 This application is described in further detail.

[0052] The embodiment of the present application discloses a mobile toilet for use in a ward. Figure 1-Figure 7 The mobile toilet used in the ward includes a movable toilet body 1 and an exhaust system 2. The exhaust system 2 is covered on the outside of the toilet body 1 and fixed to the toilet body 1. The toilet body 1 includes a seat plate 11, a back plate 12 and support columns 13 fixed to each other. The back plate 12 is set on the top surface of the seat plate 11, and the support columns 13 are fixed at the four corners of the bottom surface of the seat plate 11. The bottom end of each support column 13 is equipped with a lockable universal wheel to move and lock the toilet body 1. The seat plate 11 is hollow, and an opening is set at the top of the seat plate 11. A collector 3 is set inside the seat plate 11 and is arranged opposite to the opening for collecting patient excrement. The collector 3 is slidably connected to the seat plate 11, so that the collector 3 can be taken out in front of the seat plate 11 to clean the patient's excrement.

[0053] The seat plate 11 and the back plate 12 are used to provide support for the patient during the toileting process, and the collector 3 arranged inside the seat plate 11 is used to collect the patient's excrement for unified treatment. Its function is the same as that of a traditional toilet, and it is convenient for medical staff to move and deploy quickly in an emergency. At the same time, the exhaust system 2 covered on the outside of the toilet body 1 is used to ensure air circulation and freshness, while also protecting the patient's privacy. When the patient needs to defecate, the call staff can easily transfer the patient from his bed to the mobile toilet, and at the same time can maintain continuous monitoring of the patient's vital signs, providing a convenient, safe and hygienic toilet solution for people with limited mobility such as critically ill patients. Nursing staff do not need to frequently assist patients to go to and from the toilet, saving physical strength and time, and ensuring that the patient's needs are effectively addressed.

[0054] As a preferred embodiment, the seat 11 is provided with two sets of armrests 14, at least one of which is equipped with a call button 15, allowing patients to call medical staff during or after using the toilet. The two sets of armrests 14 are respectively provided on either side of the opening. Because critically ill and heavy patients are inconvenient to transfer, a first rotating shaft 141 is provided on the seat 11. In the embodiment of the present application, the first rotating shaft 141 is a damping shaft. The bottom end of the armrest 14 is rotatably connected to the seat 11 via the first rotating shaft 141 so that it can rotate away from the opening. A locking assembly 16 is provided inside the seat 11 to maintain the armrest 14 at a certain angle.

[0055] By utilizing the rotatable armrest 14, when the patient needs to move, it can be rotated to a certain angle, thereby reducing the height of the patient during movement, reducing the risk of movement, and avoiding the safety hazard of patients who are bedridden or have limited mobility falling due to lack of physical strength, dizziness or limb weakness. At the same time, the locking component 16 can be used to keep the armrest 14 at a certain angle, thereby reducing the complexity of operations for medical staff during the patient's movement.

[0056] Furthermore, the locking assembly 16 includes a locking gear 161 and a locking rack 162 that mesh with each other. The locking gear 161 is coaxially fixed to the first rotating shaft 141, and the locking rack 162 is located below the locking gear 161. A second rotating shaft is provided at one end of the locking gear 161 and is rotatably connected to the base plate 11. The other end of the locking rack 162 is fixedly provided with an operating handle 163 that extends out of the base plate 11 to control the locking or separation of the locking gear 161 and the locking rack 162.

[0057] When the operating handle 163 is in the initial position, the locking gear 161 and the locking rack 162 are engaged with each other, thereby limiting the rotation of the armrest 14; when the operating handle 163 is in the end position, the locking gear 161 and the locking rack 162 are disengaged, so that the armrest 14 can be grasped at will.

[0058] An elastic member is provided on the first rotating shaft 141 to automatically return the armrest 14 to its original position. In this embodiment, the elastic member is a coil spring. One end of the elastic member is fixedly connected to the first rotating shaft 141, and the other end is fixedly connected to the inner wall of the collection box 31. A compression spring is also provided between the locking rack 162 and the collection box 31 to automatically rotate the locking rack 162 back to a position where it meshes with the locking gear 161.

[0059] By utilizing the mutually meshing locking gear 161 and locking rack 162, the armrest 14 can be locked more stably. By utilizing the elastic member, the armrest 14 can automatically rotate back to its initial position during the separation of the locking rack 162 and the locking gear 161, thereby facilitating the resetting of the armrest 14. The first rotating shaft 141 adopts a damping shaft, which can reduce the kinetic energy of the armrest 14 during rotation, thereby making the resetting process of the armrest 14 smoother, reducing the possibility of injury to the patient due to the excessively fast rotation speed of the armrest 14, and improving practical safety.

[0060] As a preferred embodiment, the armrest 14 includes a support frame 142 rotatably connected to the seat plate 11. A first support plate 143 and a second support plate 144 are provided on the support frame 142. The first support plate 143 is fixedly connected to the support frame 142, and the second support plate 144 is slidably connected to the first support plate 143 to increase the height of the armrest 14. A locking bolt 145 is threadedly connected to the second support plate 144. Tightening the locking bolt 145 causes the locking bolt 145 to abut against the first support plate 143, thereby fixing the relative position between the first support plate 143 and the second support plate 144.

[0061] The first support plate 143 and the second support plate 144 that are slidingly arranged can extend the overall length of the armrest 14. During use, the second support plate 144 can be extended and placed next to the patient's bed. At the same time, the first support plate 143 and the second support plate 144 can be used to provide support during the patient's transfer, so that the patient can be smoothly transferred from the bed to the toilet body 1 through the first support plate 143 and the second support plate 144, reducing the medical staff's handling of the patient and making the patient's transfer more convenient.

[0062] As a preferred embodiment, a stabilizing assembly 17 is provided at the bottom of the seat plate 11, and the stabilizing assembly 17 includes a retractable connecting rod 171 and a snap ring 172. One end of the connecting rod 171 is fixedly connected to the seat plate 11, and the snap ring 172 is hinged to the end of the other end of the connecting rod 171. The cross-section of the connecting rod 171 is circular so that the snap ring 172 can rotate along the circumference of the connecting rod 171. Bolts are threaded on the connecting rod 171 to fix the length of the connecting rod 171. The axis of the rotating shaft of the snap ring 172 is perpendicular to the axis of the connecting rod 171, so that the snap ring 172 can be flipped. The side wall of the snap ring 172 is provided with a snap interface 1721, which is flared. The snap ring 172 can be rotated to be mounted on the legs or beams of the bed.

[0063] During the patient transfer process, the connecting rod 171 is extended, and the clamping ring 172 is clamped on the leg or beam of the patient's bed using the clamping interface 1721 on the clamping ring 172. Through the rotatable clamping ring 172 and the clamping interface 1721 opened laterally, the clamping ring 172 can be connected or separated between the side and the bed, and good axial limitation can be obtained, thereby improving the connection stability between the clamping ring 172 and the bed.

[0064] In a preferred embodiment, collector 3 includes a collection box 31 and a collection bag 32. The top of collection box 31 is provided with an opening, which is positioned opposite the opening of seat plate 11. A flange 33 is provided on the top surface of collection box 31 to hold collection bag 32 open. Collection bag 32 can be tied to flange 33 with an elastic band or rope. A closure assembly 34 is also provided on the top of collection box 31 to seal collection bag 32.

[0065] The patient's excrement can be collected by using the collection box 31 and the collection bag 32. The flange 33 on the top surface of the collection box 31 can be used to tie the bag opening of the collection bag 32 to the flange 33 to keep the bag opening open. At the same time, the bag opening of the collection bag 32 can be opened and closed in time by using the closing component 34, which is convenient for quick cleaning and disinfection. At the same time, the closing component 34 can reduce the odor and leakage of excrement overflow, reducing the risk of cross infection.

[0066] Furthermore, the closing assembly 34 includes a plurality of fan-shaped sealing plates 341, which are slidably connected to the collection box 31 along the radial direction of the opening. The plurality of fan-shaped sealing plates 341 can be assembled into a complete circular plate. The outer periphery of the opening is rotatably connected to a drive ring 342, which is provided with a spiral drive groove 3421. A slider 3411 is fixedly provided on the sealing plate 341, and the slider 3411 is located in the drive groove 3421. A telescopic push-pull device 343 is provided in the collection box 31 to drive the drive groove 3421 to rotate. When the telescopic push-pull device 343 is extended or shortened, the drive ring 342 rotates, and the spiral drive groove 3421 drives the sealing plates 341 to move toward or away from each other. The edges of the sealing plates 341 are made of elastic material to reduce hard contact with the collection bag 32.

[0067] By adopting the above-mentioned technical solution, using multiple fan-shaped sealing plates 341 and driving rings 342, the sealing plates 341 can be driven at the same time, and the edges of the sealing plates 341 are used to squeeze the collection bag 32 to achieve the effect of sealing the collection bag 32. The spiral driving groove 3421 makes the driving of the sealing plate 341 by the driving ring 342 smoother, reducing the risk of the sealing plate 341 causing damage to the collection bag 32.

[0068] As a preferred embodiment, a heater 111 is embedded in the seat plate 11. A flexible filler is provided on the front of the back plate 12. The back plate 12 is hollow and contains a deodorizing material 4. In the embodiment of the present application, the deodorizing material 4 is activated carbon. The side walls of the back plate 12 are provided with ventilation holes.

[0069] The heater 111 can heat the seat 11 to a certain temperature, improving patient comfort during use, reducing psychological stress during recovery, and enhancing patient confidence in self-care. The padded back panel 12 reduces hard contact between the patient and the back panel 12, further improving patient comfort during use. The deodorizing material 4 placed inside the back panel 12 reduces odors in the portable restroom, ensuring hygiene during use.

[0070] The exhaust system 2 is covered on the outside of the toilet body 1. The exhaust system 2 includes a pressure sensor and an exhaust component arranged on the top of the seat ring box 11. The exhaust component is used to extract the air around the toilet body 1 and transport it to a set position.

[0071] When the pressure sensor detects pressure at both the first time and the second time, the exhaust assembly operates for a first set time, and the interval between the first time and the second time is a second set time.

[0072] Specifically, a groove is provided on the top of the seat ring box 11, into which a pressure sensor is embedded. The exhaust system 2 also includes a controller connected to the pressure sensor and the exhaust assembly signal. The controller receives the signal detected by the pressure sensor and sends a signal to the exhaust assembly to control the operation of the exhaust assembly.

[0073] The first set time and the second set time are both times set by the designer, but can also be set by the user as needed. In this embodiment, the first set time is 60 seconds and the second set time is 20 seconds. With a 20-second cycle, when the pressure sensor detects pressure at both the beginning and end of the cycle, the controller sends a signal to the exhaust assembly, and the exhaust assembly operates for 60 seconds. If the pressure sensor does not detect pressure at the end of the cycle, the controller no longer sends a signal to the exhaust assembly, and the exhaust assembly ends after completing 60 seconds of the previous cycle.

[0074] It should be noted that, in this embodiment, the controller is integrated with the air dynamic device 24. The air dynamic device 24 is turned on and off when the exhaust assembly is running and finished.

[0075] The exhaust assembly includes an exhaust bracket 21, an aerodynamic device 24, an exhaust pipe and a curtain 22; wherein, the exhaust bracket 21 is fixed on the seat ring box 11, the exhaust bracket 21 is hollow, and a plurality of ventilation holes 211 are opened on the exhaust bracket 21, and the ventilation holes 211 are used to absorb the air around the toilet body 1.

[0076] The air inlet end of the aerodynamic device 24 is connected to the inner cavity of the exhaust bracket 21, and the air outlet end is connected to the exhaust pipe. The aerodynamic device 24 is connected to the pressure sensor signal. The aerodynamic device 24 is used to extract air from the inner cavity of the exhaust bracket 21 and send it into the exhaust pipe, so that a negative pressure is formed in the inner cavity of the exhaust bracket 21.

[0077] The barrier curtain 22 is hung and surrounds the outside of the toilet body 1 .

[0078] As a preferred embodiment, the exhaust system 2 includes an exhaust bracket 21, a curtain 22, and a lighting system 23. The bottom end of the exhaust bracket 21 is fixed to the seat plate 11 so that it moves simultaneously with the toilet body 1. The curtain 22 is hung on the exhaust bracket 21, and a notch is provided on one side of the curtain 22 to facilitate the patient's entry into the curtain 22. The exhaust bracket 21 is hollow and is also fixed with an aerodynamic device 24. The exhaust bracket 21 has multiple ventilation holes 211 connecting the two sides of the curtain 22. The air inside the curtain 22 is exchanged with the air outside the curtain 22 through the aerodynamic device 24.

[0079] Furthermore, the aerodynamic device 24 is in communication with the interior of the back plate 12 .

[0080] The air around the toilet body 1 in the curtain 22 passes through the ventilation holes 211 and enters the back panel 12 from the exhaust bracket 21. The deodorizing material 4 in the back panel 12 filters the air in the curtain 22, and then passes through the aerodynamic device 24 and is discharged to the outside of the curtain 22 through the exhaust pipe, thereby reducing pollution to the external air.

[0081] The exhaust system 2 can be used to exchange the air inside and outside the curtain 22. Under the drive of the air dynamic device 24, the air outside the curtain 22 enters the curtain 22 through the ventilation holes 211 on the hollow exhaust bracket 21, and the ventilation inside the curtain 22 is discharged to the outside of the curtain 22 through the air dynamic device 24, which can maintain the air flow inside the curtain 22 and improve the air quality in the mobile toilet.

[0082] The implementation principle of a mobile toilet in a ward of an embodiment of the present application is as follows: during use, the curtain 22 is first pushed aside, and the medical staff unlocks and screws the locking bolt 145 and unfolds the first support plate 143 and the second support plate 144, and then presses down the operating handle 163 to separate the locking rack 162 and the locking gear 161 from each other, and then rotates the armrest 14 and puts the second support plate 144 together with the patient's bedside. Next, the connecting rod 171 is extended, and the snap ring 172 is rotated to clamp the snap ring 172 on the support leg or beam of the bed, and then the telescopic push-pull device 343 is driven to make the sealing plate 341 open the bag mouth of the collection bag 32, and then the patient is moved to the toilet body 1 and the curtain 22 is blocked. After the patient uses the toilet, the above steps are reversed to complete the patient's re-transfer and the cleaning of the patient's excrement.
