Description

Technical Field

[0001] The invention relates to the field of nursing beds for defecation and urination, and in particular to a toilet seat for a nursing bed for defecation and urination and a method thereof. Background Art

[0002] As the number of disabled / semi-disabled elderly people gradually increases, the decline in their physiological functions forces them to stay in bed for long-term care. However, traditional nursing beds still use methods that meet the patient's sitting posture or toilet function, and cannot meet the patient's physiological needs for urination and defecation. The current nursing beds can enable patients to defecate in bed, and use the bedpan to collect and process excrement. However, after the patient defecates in bed, the patient's body is cleaned by spraying water. Since spraying water requires a water flow with a certain pressure, the flushing water flow is prone to splashing, making it easy for the splashing water to overflow between the patient's body above the bedpan and the bed, contaminating the mattress around the bedpan, and the mattress is inconvenient to clean and replace; if the water pressure of the spray flushing water flow is reduced, it will affect the cleaning effect of dirt attached to the patient's body and increase the cleaning time.

[0003] A Chinese patent (publication number CN 219184615 U) discloses a nursing bed with a function of draining and cleaning a toilet bowl. A toilet bowl is embedded in the bed body. The nursing bed also includes a flushing mechanism and a drainage mechanism. The flushing mechanism includes a number of nozzles, a water supply pipe and a water supply pump installed on the inner wall of the toilet bowl. At least some of the nozzles are universal nozzles. After the patient defecates, the toilet bowl and the patient's defecation area can be automatically and comprehensively and effectively flushed and cleaned, and the flushing angle can also be adjusted. However, it only considers the problem of flushing and cleaning the toilet bowl and the patient's defecation area, and does not consider the possible leakage of water during the flushing and cleaning process. This also leads to the problem that the mattress around the toilet bowl is easily wetted and contaminated due to the leakage of water during flushing, which affects the hygiene of the nursing bed. Summary of the invention

[0004] The purpose of the present invention is to address the defects of the prior art and to provide a toilet seat and method for a nursing bed with two toilets. The air bag connected to the toilet seat body is expanded to fit the patient's body, so that the fitting position forms a limited area to block the flow of water. After the water flows to contact the air bag, it is blocked by the air bag and flows downward into the toilet bowl, preventing the water from flowing along the body to outside the opening of the toilet bowl, thereby reducing the pollution caused by water leakage. At the same time, the pressure of the air bag is reduced to shrink and then be stored. The contact area on the top of the stored air bag is flush with the surface of the toilet seat body, thereby reducing the discomfort caused to the human body by the protrusion and improving the comfort.

[0005] The first object of the present invention is to provide a toilet seat for a nursing bed with two stools, which adopts the following scheme: The utility model comprises a toilet seat body and an airbag, wherein the toilet seat body is provided with a toilet hole, and the airbag is distributed in a strip shape along the opening edge of one end of the toilet hole, and the airbag is provided with a fixing area and a contact area, and the fixing area is connected to the toilet seat body along the opening edge of one end of the toilet seat, and the contact area and the fixing area are distributed relatively to each other. When the air pressure in the airbag is adjusted, the contact area protrudes from the surface of the toilet seat body, and the distance between the contact area and the fixing area changes, so that the contact area keeps fitting the human body or fits in the fixing area for storage.

[0006] Furthermore, the interior of the airbag is divided into a plurality of chambers, and each chamber is connected to a pressure gas source via a separate control valve.

[0007] Furthermore, the chamber is connected to the sub-control valve through an air pipe, and an air pressure sensor is connected in series to the air pipe connected to the chamber. The air pressure sensor is connected to the controller, and the air pressure sensor is used to send air pressure information in the chamber to the controller.

[0008] Furthermore, the plurality of chambers are divided sequentially along the strip distribution direction of the airbags, and diaphragms are provided between adjacent chambers to form partitions.

[0009] Furthermore, the airbags are distributed along the toilet seat body to form a U-shape, and an installation portion is formed at an opening position of one end of the toilet hole of the toilet seat body where the U-shaped airbag is not arranged, so as to install the urine shield.

[0010] Furthermore, the airbag side portion is between the contact area and the fixing area, and when the airbag is stored, the airbag side portion is folded between the contact area and the fixing area.

[0011] Furthermore, a plurality of pressure sensors are provided on the surface of the toilet seat body, and the pressure sensors are arranged in sequence and at intervals around the toilet hole.

[0012] Furthermore, the pressure sensors are respectively connected to the controller.

[0013] The second object of the present invention is to provide a working method of the toilet seat for a nursing bed with two toilets as described in the first object, comprising: When not defecating, the air pressure in the airbag is reduced to shrink the airbag, and the contact area fits the fixed area and is stored, and the surface of the contact area is flush with the surface of the toilet seat body; During defecation and post-defecation cleaning, the air pressure in the airbag is increased to expand the airbag, and the contact area gradually moves away from the fixed area, so that the airbag protrudes from the surface of the toilet seat body, and the contact area fits the user's body to block the leakage of water; After the human body is cleaned, the airbag is cleaned and dried, and the air pressure in the airbag is reduced to shrink the airbag and return to the storage state.

[0014] Furthermore, after the airbag is inflated, the contact area can form a U-shaped curve, which is combined with the external urine shield to form a closed curve to prevent the leakage of washing water.

[0015] Compared with the prior art, the present invention has the following advantages and positive effects: (1) In order to solve the problem that water is easily leaked out and causes pollution when washing and cleaning the human body during use of the current nursing bed, the airbag connected to the toilet seat body is expanded to fit the patient's body, so that the fitting position forms a limited area to block the flow of water. After the water flows to the contact airbag, it is blocked by the airbag and flows downward into the toilet bowl, preventing the water from flowing along the body to the outside of the toilet bowl opening, thereby reducing the pollution caused by water leakage. At the same time, the airbag pressure is reduced so that the airbag shrinks and is stored. After the airbag is stored, the contact area on the top of the airbag is flush with the surface of the toilet seat body, reducing the discomfort caused by the protrusion to the human body and improving the comfort.

[0016] (2) Reduce splashing and leakage when flushing the body, and reduce pollution to the outside of the toilet seat. In addition, when the airbag is inflated and fits the human body, the external flushing element can be used to flush the side of the airbag body that is easily exposed to dirt. During the flushing process, since it is in a close fit, it will not cause leakage of pollutants. Combined with air drying, the airbag body can be kept clean and hygienic for use.

[0017] (3) When the airbag is in the storage state, the side of the airbag is folded and stored between the contact area and the fixed area, making the entire airbag structure more compact. After the side of the airbag is folded and stored, the contact area with the external environment is reduced, thereby reducing the risk of contamination. When cleaning and drying the airbag, the folded and stored airbag structure makes the cleaning process simpler and more convenient, and the water between the contact area and the fixed area can be discharged by squeezing, which can make it easier to remove stains and residual moisture.

[0022] Example 1 In a typical embodiment of the present invention, Figure 1-Figure 2 As shown, a toilet seat for a nursing bed with two bowel movements is provided.

[0023] The current nursing bed for two defecations and one urination can flush and clean the human body and the toilet bowl, but only the flushing and cleaning problem is considered, and the problem of water leakage that may be caused during the flushing process is not dealt with, which may cause water splashes to leak out during flushing, wet the mattress around the toilet bowl, causing pollution, and thus affecting the hygiene of the nursing bed. Based on this, this embodiment provides a toilet seat and method for a nursing bed for two defecations and one urination, which solves the problem of water leakage during the flushing and cleaning process, and at the same time improves the comfort of the patient.

[0024] like Figure 1 As shown, the toilet seat for the nursing bed for two defecations mainly includes a toilet seat body 1, an airbag 2 and a pressure sensor 5. The toilet seat body 1 is a bearing structure of the main body, which can cooperate with the toilet bowl on the nursing bed for two defecations, and is buckled on the top opening of the toilet bowl. The toilet bowl body is provided with a toilet hole 3 for patients to use for excretion, so that the excrement passes through the toilet hole 3 and falls into the toilet bowl. The toilet hole 3 is a through-hole structure, and the airbag 2 is arranged at the edge of the opening facing the human body, so that the airbag 2 is distributed in a strip shape, and the opening of the toilet hole 3 away from the human body faces the toilet bowl.

[0025] The airbag 2 is divided into a fixed area and a contact area 4. The fixed area is connected to the toilet seat body 1 along the edge of the opening at one end of the toilet seat, and plays the role of fixing the airbag 2. The contact area 4 is distributed relative to the fixed area. When the air pressure in the airbag 2 is adjusted, the airbag 2 can be expanded or contracted. When the air pressure in the airbag 2 is maintained, the shape of the airbag 2 is also maintained. When the airbag 2 is expanded, the fixed area keeps the airbag 2 connected to the toilet seat body 1, so that the contact area 4 is away from the fixed area. The contact area 4 can protrude from the surface of the toilet seat body 1, forming a structure that fits the human body or fits the fixed area. When the airbag 2 shrinks, the contact area 4 gradually approaches the fixed area until it fits the fixed area and is flush with the surface of the toilet seat body as a whole.

[0026] By adjusting the air pressure in the airbag 2, the distance between the contact area 4 and the fixed area can be changed, so that the contact area 4 can remain close to the human body or be stored in the fixed area. When the airbag 2 is inflated, the contact area 4 fits the human body, forming a limiting area to block the flow of water, preventing water from flowing along the body to outside the opening of the toilet bowl. When the pressure of the airbag 2 is reduced to shrink the airbag 2, the contact area 4 is stored under the surface of the toilet seat body 1 and is flush with the surface of the toilet seat body 1, reducing the discomfort caused to the human body by the protrusion.

[0027] By introducing the airbag 2 structure and configuring the fixing area and the contact area 4, the problem of water leakage during the flushing and cleaning process is solved. When the airbag 2 is expanded, it can fit the human body to form a limiting area to block the flow of water, effectively preventing water from leaking out, avoiding the problem of wetting the mattress around the toilet and causing pollution.

[0028] After installing the bedpan on the two-toilet nursing bed, a urine shield needs to be installed at the rear end of the bedpan to meet the patient's urination and defecation needs in a supine position. A nozzle can be installed on the urine shield to spray water or output dry air to clean or dry the patient's body. When spraying water to clean the patient's body, the water attached to the body will flow along the legs to the outside of the bedpan opening. In this embodiment, the airbag 2 connected to the toilet seat body 1 is expanded to fit the patient's body, so that the fitting position encloses a limited area to block the flow of water. After the water flows to contact the airbag 2, it is blocked by the airbag 2 and flows downward into the bedpan, preventing the water from flowing along the body to the outside of the bedpan opening, reducing the pollution caused by water leakage.

[0029] It can be understood that in this embodiment, after the toilet seat body 1 is installed on the toilet bowl, other positions on the surface of the toilet seat body 1 where the airbag 2 is not installed serve as bearing positions, and the airbag 2 is used together with the mattress of the two-defecation nursing bed to bear the user. In the standby state, the airbag 2 is tightened and fits the toilet bowl body, which minimizes the contact with the human buttocks and ensures the comfort of lying in bed; in the defecation state, the airbag 2 is inflated and fits tightly with the buttocks, providing defecation support and waterproof and anti-fouling effects for the buttocks. The surface of the airbag 2 is not easy to stick to dirt, can be scrubbed and cleaned, and can be dried.

[0030] like Figure 1 and Figure 2 As shown, since the position where the airbag 2 contacts the user's body is relatively long, different areas of the human body need to provide different support forces to ensure comfort. In this regard, in this embodiment, the airbag 2 is designed to have a structure containing multiple chambers inside. Each chamber is connected to the pressure gas source through a sub-control valve to achieve independent control. The chamber is connected to the sub-control valve through an air pipe to achieve gas input and output. In order to achieve the air pressure change in the chamber of the airbag 2, an air pressure sensor is connected in series on the air pipe to monitor the air pressure change in the chamber in real time. The air pressure sensor sends the collected air pressure information to the controller, and the controller regulates the airbag 2 based on this information.

[0031] The chamber is connected to the sub-control valve through an air pipe to realize the input and output of gas. A pressure sensor is connected in series on the air pipe to monitor the pressure change in the chamber in real time. By dividing the airbag 2 into multiple chambers and independently controlling them through the sub-control valve, precise adjustment of different areas can be achieved to improve the user's comfort and support. The introduction of the pressure sensor can monitor the pressure change in the airbag 2 in real time, ensure the stability and safety of the airbag 2, and avoid safety problems caused by excessive or low pressure.

[0032] Multiple chambers are divided in sequence along the strip distribution direction of the airbag 2 to form a multi-stage structure. Adjacent chambers are separated by diaphragms to ensure the independence and sealing of the gas.

[0033] The air pressure sensor is a component that can sense and measure gas pressure. The air pressure sensor is used to monitor the air pressure changes in the internal chamber of the airbag 2. When the user's posture changes, his center of gravity also shifts, and the external pressure applied to different positions of the airbag 2 also changes. When the air pressure in the airbag 2 changes, the air pressure sensor can capture this change in real time and convert it into an electrical signal for output and send it to the controller.

[0034] The controller is used to determine the state of the airbag 2 based on the received air pressure information. For example, when the air pressure is lower than the preset value, the controller may determine that the airbag 2 needs to be inflated; and when the air pressure is higher than the preset value, it may determine that the airbag 2 needs to be deflated. Based on the judgment result, the controller will issue instructions to the inflation or deflation system of the airbag 2. These instructions can be used to control the airbag 2 through actuators such as sub-control valves. During the control process, the controller may also continuously obtain feedback information through the air pressure sensor to adjust the accuracy and execution effect of the instructions. For example, if the air pressure in the airbag 2 is still lower than the preset value after inflation, the controller will increase the duration or intensity of the inflation instruction to keep the airbag 2 in close contact with the user's body.

[0035] The airbags 2 are distributed along the toilet seat body 1 to form a U-shaped structure, covering most of the toilet seat area. At the opening position at one end of the toilet hole 3, the part without the airbags 2 forms a mounting portion for mounting a urine shield. The design of the U-shaped airbags 2 can better adapt to the shape of the toilet seat and the user's posture, improving the comfort and convenience of use. At the same time, the setting of the mounting portion also facilitates the installation of accessories such as urine shields, increasing the functionality and practicality of the product.

[0036] When the airbag 2 is stored, its side can be folded and placed between the contact area 4 and the fixing area to reduce the occupied space. In the different stages of non-defecation, defecation and post-defecation cleaning, as well as washing and drying the airbag 2, the airbag 2 adapts by expanding or contracting.

[0037] When the airbag 2 is in the storage state, the side of the airbag 2 is folded and stored in the space between the contact area 4 and the fixed area, making the entire airbag 2 structure more compact and not occupying additional space. When the airbag 2 is not in use, the surface of the toilet seat remains flat, and the bulge of the airbag 2 will not cause discomfort to the user or affect the appearance. After the side of the airbag 2 is folded and stored, the contact area with the external environment is reduced, thereby reducing the risk of contamination. When the airbag 2 is cleaned and dried, the folded and stored structure of the airbag 2 makes the cleaning process simpler and more convenient, and the stains and residual moisture can be more easily removed through the squeezing effect during the contraction process. When the airbag 2 is stored, the side of the airbag 2 is folded between the contact area 4 and the fixed area, reducing the wear and deformation caused by frequent expansion and contraction, thereby improving the durability and service life of the airbag 2. It also helps to maintain the shape and elasticity of the airbag 2, ensuring that it can be quickly and effectively expanded and fit the human body when needed.

[0038] On the surface of the toilet seat body 1, a plurality of pressure sensors 5 are arranged in sequence around the toilet hole 3. These pressure sensors 5 are also connected to the controller to monitor the user's usage status and comfort. The pressure sensors 5 can sense the pressure distribution of the contact surface between the user and the toilet seat in real time. When the user lies flat and contacts the toilet seat, the weight and posture will cause different pressure distribution patterns. These pressure data are captured by the sensor and converted into electrical signals, which are then processed and analyzed by the electronic system.

[0039] The pressure sensor 5 surrounds the toilet hole 3. According to the principle of ergonomics, the sensor is arranged at key stress points, such as the buttocks and the root of the thigh, to obtain more comprehensive pressure distribution data. The sensor converts the captured pressure data into an electrical signal and transmits it to the data acquisition module via wired or wireless means. The data acquisition module amplifies, filters and digitally processes the received electrical signal to extract useful pressure distribution information. The analysis results are presented to users or product developers in an intuitive manner (such as charts, reports, etc.), providing data support for product optimization and personalized customization.

[0040] Based on the analysis results, the shape, material, airbag 2 layout, etc. of the toilet seat can be optimized, and the pressure of the airbag 2 chamber at the corresponding position can be adjusted according to the pressure distribution to improve the comfort and support of the toilet seat for defecation and urination care.

[0041] Example 2 In another typical embodiment of the present invention, Figure 1-Figure 2 As shown, a working method of a toilet seat for a nursing bed with two stools is provided, using the toilet seat for a nursing bed with two stools as in Example 1.

[0042] A working method of a toilet seat for a nursing bed comprising: When not defecating, the air pressure in the airbag 2 is reduced to shrink the airbag 2, and the contact area 4 is accommodated in the fixed area, and the surface of the contact area 4 is flush with the surface of the toilet seat body 1; During defecation and post-defecation cleaning, the air pressure in the airbag 2 is increased to expand the airbag 2, and the contact area 4 gradually moves away from the fixed area, so that the airbag 2 protrudes from the surface of the toilet seat body 1, and the contact area 4 fits the user's body to block the leakage of water; After the human body is cleaned, the airbag 2 is cleaned and dried, and the air pressure in the airbag 2 is reduced to shrink the airbag 2 and return to the storage state.

[0043] After the airbag 2 is inflated, the contact area 4 can form a U-shaped curve to adapt to the user's body surface, and form a closed curve in combination with the external urine shield to prevent the leakage of cleaning water.

[0044] The airbag 2 is flush with the surface of the toilet seat body 1 in the stored state, which will not cause discomfort or foreign body sensation to the user. When needed, the airbag 2 can expand quickly and fit the human body to form an effective limiting area to block the flow of water, thereby improving the comfort and satisfaction of the user.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
