Description

Technical Field

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

[0002] With the development of society and the aging of the population, the number of long-term bedridden patients has increased, and the functionality and comfort of nursing beds have become increasingly important. Traditional nursing beds use an embedded bedpan design to reduce the inconvenience of patient movement, but the existing bedpan system mostly relies on the patient to actively operate the bedpan lid, which is a great obstacle for patients with incontinence or cognitive impairment (such as patients with Alzheimer's disease). They cannot open the bedpan lid on their own, resulting in the inability of excrement to fall accurately, affecting the effectiveness of the bedpan, causing discomfort and hygiene problems, and reducing the user experience.

[0003] A Chinese patent (publication number CN116270071A) discloses a nursing bed with an automatic bedpan system. The user lies on the bed with the buttocks facing the bedpan. When the user defecates, the urine in the excrement will be blocked by the urine cover and then fall on the upper surface of the basin cover, and the feces will directly fall on the upper surface of the basin cover. Since the excrement is a wet object, it will trigger several humidity sensing switches on the upper surface of the basin cover, and the controller will immediately control the cover opening mechanism to open the basin cover. The user's subsequent defecation will automatically fall into the bedpan, and the excrement previously falling on the basin cover will also fall into the bedpan; currently, when cleaning the bedpan, it mostly relies on the water spray element embedded in the bedpan for flushing, but with the installation of the water spray element, there will also be a cleaning dead angle at its installation position, resulting in poor cleaning effect at the installation position of the water spray element, and reducing the installation of the water spray element on the bedpan requires increasing the cleaning range of a single water spray element, and it is necessary to increase the water pressure and more easily cause splashing and overflowing problems, affecting the sanitation and safety of the bedpan of the nursing bed with two defecations. Summary of the invention

[0004] The purpose of the present invention is to provide a bedpan cover and method for a double-defecation nursing bed in view of the defects of the prior art. By distributing the nozzles on the circumferential sides of the cover body, the bedpan cover and the bedpan can be cleaned in all directions, avoiding the problem of cleaning dead corners. The nozzles adjust their directions as the bracket and the cover body rotate, thereby ensuring uniformity and comprehensiveness of cleaning. Since the nozzles are distributed on the circumferential sides of the cover body instead of being concentrated inside the bedpan, even if the water pressure is increased, there will be no obvious splashing and overflowing problems. By accurately controlling the water spraying amount and spraying time of the nozzles, the risk of splashing and overflowing can be further reduced.

[0005] The first object of the present invention is to provide a bedpan cover for a nursing bed with two urination and defecation, adopting the following scheme: It includes a cover body, a nozzle and a bracket. The cover body is rotatably installed on the external toilet bowl through the bracket. One side of the cover body is a detection surface. A feces storage tank is arranged on the detection surface. The feces storage tank is connected to a urinary catheter tank. A defecation identification element is installed in the feces storage tank. The circumferential side of the cover body is distributed around the detection surface and is equipped with nozzles. A water supply pipeline is embedded in the cover body. The nozzles are respectively connected to the water supply pipelines. The directions of the nozzles are adjusted as the bracket drives the cover body to rotate. The water supply pipeline is connected to an external pressure water source.

[0006] Furthermore, both sides of the feces storage tank are connected to urinary catheterization grooves respectively, and the urinary catheterization grooves extend to the ends of the cover body. The urinary catheterization grooves and the feces storage tank are distributed on the connecting line at the two ends of the cover body.

[0007] Furthermore, the urine-conducting groove is distributed obliquely, and the depth of the urine-conducting groove relative to the detection surface gradually increases along the direction from the end of the cover body to the feces storage tank.

[0008] Furthermore, in a direction perpendicular to the line connecting the two ends of the cover body, the width of the feces storage groove is greater than the width of the urinary catheter groove, and the position where the feces storage groove connects to the urinary catheter groove has a smooth transition.

[0009] Furthermore, the defecation identification element includes a temperature sensor and a humidity sensor, and a humidity sensor is also arranged on the side wall of the urinary catheter.

[0010] Furthermore, one end of the bracket is connected to a side of the cover body away from the detection surface, and the other end extends to the outside of the cover body in a direction perpendicular to a line connecting two ends of the cover body.

[0011] Furthermore, a plurality of nozzles are installed on the circumferential side of the cover body, and adjacent nozzles are distributed at intervals, and output ends of the nozzles face in a direction away from the cover body.

[0012] Furthermore, the multiple nozzles are divided into multiple groups, and each group of nozzles is connected to the same water supply pipeline through a control valve, and the water supply pipeline is a channel distributed inside the cover body.

[0013] The second object of the present invention is to provide a working method of a bedpan cover for a nursing bed with two stools as described in the first object, comprising: The cover body is installed on the bedpan of the double-defecation nursing bed through a bracket. The bracket rotates to drive the cover body to flip and block the bedpan opening. The bracket rotates in the opposite direction to drive the cover body to rotate to the side of the bedpan below the bedpan opening. When the cover body blocks the opening of the toilet bowl, it can support the user. When the defecation recognition element recognizes urination or defecation, the bracket drives the cover body to flip to open the opening of the toilet bowl. After use, water is delivered into the water supply pipeline and sprayed on the inner wall of the toilet bowl through the nozzle to clean the inner wall of the toilet bowl; After the cover and the toilet bowl are cleaned, the bracket rotates to drive the cover to flip and block the toilet bowl opening, waiting for the next defecation to be identified.

[0014] Furthermore, when the nozzle sprays water to clean the inner wall of the toilet bowl, the bracket drives the cover body to rotate and adjust the angle, and repeatedly swings to clean the inner wall of the toilet bowl.

[0015] Compared with the prior art, the present invention has the following advantages and positive effects: (1) In order to solve the problem of blind corners caused by too many cleaning elements such as water spray elements in the toilet bowl, the nozzles are distributed on the circumferential side of the cover body, so that the toilet bowl cover and the toilet bowl can be cleaned in all directions, avoiding the problem of blind corners. The nozzles adjust their directions as the bracket and the cover body rotate, ensuring uniformity and comprehensiveness of cleaning. Since the nozzles are distributed on the circumferential side of the cover body instead of being concentrated inside the toilet bowl, even if the water pressure is increased, there will be no obvious splashing and overflowing problems.

[0016] (2) The nozzles are divided into multiple groups and connected to the same water supply pipeline through control valves. The water spray volume and spray time of the nozzles can be precisely controlled to further reduce the risk of splashing and overflow, thereby maintaining the hygiene of the defecation and confinement care bed.

[0017] (3) By designing the connecting structure between the urinary catheter and the fecal storage tank, effective collection of urine and feces is achieved. The inclined distribution of the urinary catheter and the smooth transition design between the fecal storage tank and the urinary catheter improve the collection efficiency of urine and feces, improve the collection efficiency and hygiene, and install temperature sensors and humidity sensors to monitor defecation activities in real time, thereby triggering the corresponding cleaning or treatment mechanism. The nozzle is arranged on the cover to achieve automatic cleaning of the cover and its surrounding area, reducing the frequency and difficulty of manual cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Example 1 In a typical embodiment of the present invention, Figure 1-Figure 2 As shown, a bedpan cover for a nursing bed is provided.

[0023] At present, the nursing bed with automatic bedpan system realizes the automatic opening of the bedpan cover and the automatic falling of excrement into the bedpan, but there are problems in cleaning the bedpan. The water spray element embedded in the bedpan is easy to form a cleaning dead corner at the installation position, and the cleaning effect of these positions is poor, which affects the sanitation and safety of the bedpan. In order to reduce the cleaning dead corner, it is necessary to increase the cleaning range of a single water spray element, but this usually requires increasing the water pressure, and increasing the water pressure is prone to splashing and overflowing, further affecting the sanitation and safety of the nursing bed for two urination and defecation. Based on this, this embodiment proposes a bedpan cover for a nursing bed for two urination and defecation, and the nozzle 3 for cleaning the bedpan is integrated and installed on the cover body 2 of the bedpan cover, reducing the number of nozzles 3 set inside the bedpan, thereby reducing the cleaning dead corners existing on the inner wall of the bedpan, and the nozzle 3 moving with the cover body 2 can adjust the direction and work within the range of the bedpan, solving the problems of cleaning dead corners and splashing and overflowing, and improving the cleaning effect and sanitation and safety of the bedpan.

[0024] like Figure 1 As shown, the bedpan cover for the two-defecation nursing bed mainly includes a cover body 2, a bracket 4 and a defecation identification element 1. The cover body 2 is used in combination with the bedpan of the two-defecation nursing bed. The cover body 2 can block the opening of the bedpan, and can also leave the opening position of the bedpan to open the opening of the bedpan. When the cover body 2 blocks the opening of the bedpan, it can contact the user's body and support the user's body part. The bracket 4 is connected to the cover body 2, and the cover body 2 is installed in the bedpan position of the two-defecation nursing bed through the bracket 4. The bracket 4 drives the cover body 2 to complete the required rotation and flipping actions to achieve blocking or opening the opening of the bedpan.

[0025] The cover body 2 is rotatably mounted on the external toilet bowl through the bracket 4, and the direction can be adjusted as the bracket 4 rotates. One side of the cover body 2 is a detection surface for detecting the presence of excrement. A feces storage tank is provided on the detection surface for temporarily storing excrement. The feces storage tank is also connected to a urinary catheterization tank, which can guide excrement outside the range of the feces storage tank into the feces storage tank. A feces identification element 1 is also installed in the feces storage tank for identifying the type of excrement. A plurality of nozzles 3 are distributed around the detection surface on the circumferential side of the cover body 2, and the nozzles 3 can adjust the direction as the bracket 4 drives the cover body 2 to rotate. A water supply pipeline 5 is embedded in the cover body 2, and the nozzles 3 are respectively connected to the water supply pipeline 5, and the water supply pipeline 5 is connected to an external pressure water source. The external pressure water source conveys water into the water supply pipeline 5, so that the water body is discharged through the nozzle 3 after passing through the water supply pipeline 5, forming a water jet to rinse and clean the action position.

[0026] By distributing the nozzles 3 on the circumferential sides of the cover 2, the toilet lid and toilet bowl can be cleaned in all directions, avoiding the problem of cleaning dead corners. The nozzles 3 adjust their directions as the bracket 4 and the cover 2 rotate, ensuring the uniformity and comprehensiveness of the cleaning. Since the nozzles 3 are distributed on the circumferential sides of the cover 2, instead of all the water spraying elements being concentrated inside the toilet bowl, the number of water spraying elements arranged inside the toilet bowl is reduced, while meeting the requirement of covering the cleaning range inside the toilet bowl. At the same time, the risk of splashing and overflowing can be further reduced by accurately controlling the water spraying amount and water spraying time of the nozzles 3.

[0027] By cleaning in all directions and avoiding cleaning dead corners, the bedpan cover can significantly improve the cleaning effect of the bedpan and maintain the hygiene and safety of the bedpan. Through a reasonable layout of the nozzle 3, the nozzle 3 on the cover body 2 can clean the inner wall of the bedpan in the bedpan, reducing the distance from the nozzle 3 to the target cleaning position, reducing pressure loss, and improving the water jet cleaning effect. After the cover body 2 is sealed with the opening of the bedpan, the inside of the bedpan can also be isolated from the outside world, so that when cleaning the inside of the bedpan, the problem of splashing and overflow can be effectively reduced, further ensuring the hygiene and safety of the two-defecation nursing bed.

[0028] The improvement of cleaning effect and the reduction of splashing and overflow can significantly improve the user experience and make the defecation and urination care bed more comfortable, convenient and safe.

[0029] like Figure 2 As shown, the feces storage tank is the main collection area for feces before the cover body 2 is opened, and the feces storage tank is located near the center of the cover body 2. Among them, the cover body 2 is a gourd-shaped plate structure with a narrow front end and a wide rear end. It is manufactured using PU foaming molding technology and has embedded antibacterial components to effectively inhibit bacterial growth and ensure hygiene and safety. It is not only easy to clean, but also improves the strength and durability of the bedpan cover. The gourd-shaped cover body 2 has a relatively smooth curved surface, which reduces the hiding space for dirt and bacteria, makes cleaning more convenient, keeps the equipment clean and hygienic, prevents cross infection, and ensures the health of patients. In addition, the cover body 2 can better fit the curve of the human body, effectively disperse pressure, reduce the sense of oppression on the patient's body, and reduce discomfort.

[0030] The urinary catheter is connected to the fecal storage tank and is distributed on both sides of the fecal storage tank. The urinary catheter is distributed obliquely. From the end of the cover 2 to the fecal storage tank, the depth of the urinary catheter relative to the detection surface gradually increases. The inclined urinary catheter is used to guide the urine to flow to the fecal storage tank to prevent the urine from spreading everywhere. The two sides of the fecal storage tank are connected with urinary catheters, which extend to the end of the cover 2. The urinary catheter and the fecal storage tank are distributed on the connecting line at both ends of the cover 2 to ensure that the excrement can fall smoothly into the fecal storage tank, so as to be easily identified by the defecation identification element 1, thereby triggering the action of opening the cover 2.

[0031] In the direction perpendicular to the line connecting the two ends of the cover body 2, the width of the feces storage tank is greater than the width of the urinary catheterization tank, and the feces storage tank is smoothly connected to the urinary catheterization tank, so that the feces storage tank has a basic accommodating function and reduces the overflow of excrement.

[0032] The defecation identification element 1 includes a temperature sensor and a humidity sensor for detecting defecation activities. The temperature sensor and the humidity sensor are installed in the feces storage tank, and the humidity sensor is installed in the urine catheter tank, which can identify urination faster.

[0033] The defecation identification element 1 is installed on the cover 2 and placed near the excretion organ, and the detection range is set (such as 32°C to 40°C). When the excrement (especially feces) is discharged, its temperature is different from the temperature of the surrounding environment. The temperature sensor can capture this temperature change, which is used as a basis for identifying the defecation activity. The humidity sensor is used to detect the moisture content in the excrement. Since there is a significant difference in humidity between feces and urine, the humidity sensor can be used to distinguish between feces and urine. For feces, its humidity is relatively low, but still higher than the surrounding environment. When feces are discharged, the humidity sensor can detect the change in humidity. For urine, its humidity is higher and is usually in liquid form. Therefore, the humidity sensor installed in the urinary catheter can identify the discharge of urine more quickly. Specifically, a temperature sensor and a humidity sensor are installed in the fecal storage tank and the urinary catheter respectively. The temperature sensor and humidity sensor in the fecal storage tank are used to detect the discharge of feces, while the humidity sensor in the urinary catheter is specifically used to detect urine.

[0034] When the defecation identification element 1 detects excrement, it generates corresponding electrical signals, which are collected and transmitted to the processing unit (such as a microcontroller) for further processing. The processing unit analyzes and judges based on the received signals (such as temperature, humidity, etc.) to determine whether defecation activity has occurred, and further distinguishes whether it is defecation or urination. Once the processing unit determines that defecation activity has occurred and identifies whether it is defecation or urination, the system will trigger the corresponding alarm or feedback mechanism. For example, the cover body 2 is opened so that the excrement on the cover body 2 and the user's subsequent excretion can enter the toilet bowl; for incontinent patients or the elderly, the system can automatically send an alarm message to the caregiver to prompt them to clean and care.

[0035] One end of the bracket 4 is connected to the side of the cover body 2 away from the detection surface, and the other end extends outside the cover body 2 and is connected to the toilet bowl, and is configured with a corresponding driving element. The driving element drives the cover body 2 to rotate and adjust the position through the bracket 4. The driving element can be a servo, an electric motor, a rotary cylinder, etc.

[0036] like Figure 1 and Figure 2As shown, the nozzle 3 is installed on the circumferential side of the cover body 2 for water spraying and cleaning. A plurality of nozzles 3 are installed on the circumferential side of the cover body 2, and adjacent nozzles 3 are spaced apart. The output end of the nozzle 3 faces away from the cover body 2. The nozzles 3 are divided into multiple groups, and each group is connected to the same water supply pipeline 5 through a control valve. By accurately controlling the water spraying amount and water spraying time of the nozzle 3, the risk of splashing and overflowing can be further reduced, and the use hygiene of the two-defecation nursing bed can be maintained.

[0037] By dividing the multiple nozzles 3 into multiple groups and connecting them to the same water supply pipeline 5 through control valves, more flexible water spray control can be achieved. In the actual cleaning process, some groups of nozzles 3 can be selectively opened or closed as needed, so as to more accurately cover the area to be cleaned. This group control method avoids the problem of waste of resources and poor cleaning effect caused by opening all nozzles 3 at the same time, and improves the cleaning efficiency.

[0038] Specifically, in order to achieve accurate control of the water spraying amount and water spraying time of the nozzle 3, an intelligent control system is adopted, and an intelligent control system such as a PLC (programmable logic controller) or a single chip microcomputer is introduced to accurately control the nozzle 3. Through programming settings, the water spraying amount, water spraying time and water spraying interval of each nozzle 3 or each group of nozzles 3 can be accurately adjusted.

[0039] A flow sensor may also be installed on the water supply pipeline 5 to monitor the flow of water in real time to ensure that the amount of water sprayed by the nozzle 3 meets the preset requirements. A pressure sensor may be installed to monitor the water supply pressure to avoid unstable water spraying caused by pressure fluctuations.

[0040] According to actual needs, the shape, size and water outlet design of the nozzle 3 are optimized to reduce the risk of splashing and overflowing. For example, a fan-shaped or conical water outlet can be used to make the water flow more evenly and gently sprayed. A variety of water spray modes are set in the intelligent control system, such as gentle mode, strong mode, etc., to meet the cleaning needs in different scenarios. According to actual needs, the most suitable water spray mode is selected to reduce the risk of splashing and overflowing. The group configuration control method also helps to enhance the cleaning effect. In actual applications, different nozzle 3 combinations and water spray modes can be selected according to different cleaning needs. For example, for stubborn stains or difficult-to-clean areas, a nozzle 3 combination with a larger water spray intensity can be selected for key cleaning; and for some more sensitive or easily damaged areas, a nozzle 3 combination with a smaller water spray intensity can be selected for gentle cleaning. The flexible control method makes the cleaning process more flexible and diverse, and can better meet the cleaning needs in different scenarios.

[0041] The water supply pipeline 5 is a channel distributed inside the cover body 2, which can maximize the use of the space inside the cover body 2. It avoids the space occupation problem caused by the external placement of the traditional water supply pipeline 5, making the entire device more compact and small, and suitable for installation in a toilet bowl with limited space. The water supply pipeline 5 is built into the cover body 2, which can simplify the installation and maintenance process. During installation, there is no need to worry about the layout and connection of the pipeline, just install the cover body 2 in the designated position. The water supply pipeline 5 is not easily disturbed or damaged by the external environment, which improves the durability and service life of the equipment. At the same time, since the water supply pipeline 5 is integrated with the cover body 2 structure, it can also reduce the leakage problem caused by loose or damaged pipelines.

[0042] Example 2 In another typical embodiment of the present invention, Figure 1-Figure 2 As shown, a working method of a bedpan cover for a nursing bed with two defecations and one urination is provided, using the bedpan cover for a nursing bed with two defecations and one urination as in Example 1.

[0043] A working method of a bedpan cover for a nursing bed with two defecations, comprising: The cover body 2 is installed on the toilet bowl of the two-toilet nursing bed through the bracket 4. The bracket 4 rotates to drive the cover body 2 to flip and block the toilet bowl opening. The bracket 4 rotates in the opposite direction to drive the cover body 2 to rotate to the side of the toilet bowl below the toilet bowl opening. When the cover 2 blocks the opening of the toilet bowl, it can support the user. When the defecation identification element 1 identifies urination or defecation, the bracket 4 drives the cover 2 to flip and open the opening of the toilet bowl. After use, water is supplied to the water supply pipe 5, and water is sprayed on the inner wall of the toilet bowl through the nozzle 3 to clean the inner wall of the toilet bowl; After the cover body 2 and the toilet bowl are cleaned, the bracket 4 rotates to drive the cover body 2 to flip and block the toilet bowl opening, waiting for the next defecation to be identified.

[0044] When the nozzle 3 sprays water to clean the inner wall of the toilet bowl, the bracket 4 drives the cover body 2 to rotate and adjust the angle, and repeatedly swings to clean the inner wall of the toilet bowl.

[0045] Through the design of the bracket 4 and the cover 2, the automatic blocking and opening of the toilet opening is realized, which improves the convenience and hygiene of use. The introduction of the defecation recognition element 1 can automatically identify urination or defecation and trigger corresponding actions, such as the flipping of the cover 2, which improves the intelligence level of the device. Through the design of the water supply pipeline 5 and the nozzle 3, the inner wall of the toilet can be sprayed with water to clean, reducing the trouble of manual cleaning and health hazards.

[0046] Specific, combined Figure 1 and Figure 2 , the working method of the bedpan cover for the two-defecation nursing bed is explained in detail: Initial state: the cover 2 is firmly mounted on the bedpan of the two-defecation nursing bed through the bracket 4 and is in a state of blocking the opening of the bedpan. At this time, the cover 2 can support the user and ensure the stability and safety of the user on the bedpan.

[0047] Defecation identification: When the user defecates, the defecation identification element 1 (such as a temperature sensor and a humidity sensor) will immediately detect the defecation activity. It can accurately identify whether it is defecation or urination, thereby providing an accurate signal for subsequent cleaning actions.

[0048] The cover 2 flips and the toilet bowl opening is opened: Once the defecation identification element 1 sends a signal, the bracket 4 will immediately start and drive the cover 2 to flip. This action is quick and smooth, ensuring that the user will not experience any interference or discomfort. As the cover 2 flips, the toilet bowl opening is completely opened to facilitate the discharge of excrement.

[0049] Defecation and collection: When the toilet bowl is open, the user's excrement will be discharged smoothly into the toilet bowl. The toilet bowl is designed with a reasonable collection structure to ensure that the excrement will not splash or leak.

[0050] Water spray cleaning: After use, the system will supply water to the water supply pipe 5. The water is sprayed out through the nozzle 3 at an appropriate pressure and angle to cover the entire inner wall of the toilet bowl. It can completely remove the residue and stains on the inner wall of the toilet bowl, ensuring the hygiene and cleanliness of the toilet bowl.

[0051] Angle adjustment of the cover 2 and repeated cleaning: During the water spray cleaning process, the bracket 4 will drive the cover 2 to adjust its angle. This action allows the nozzle 3 to cover the inner wall of the toilet bowl more comprehensively, ensuring that every corner can be thoroughly cleaned. By repeatedly swinging the cover 2 and the nozzle 3, the inner wall of the toilet bowl can be cleaned in all directions.

[0052] The cover 2 is reset and waits for the next defecation: After cleaning, the bracket 4 will drive the cover 2 to flip back to the initial position again to block the opening of the toilet bowl. At this time, the whole system is in standby mode, waiting for the signal of the next defecation recognition.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
