Abstract
Description
Technical Field
[0001] This invention relates to the fields of medical care equipment and environmental protection, and in particular to an intelligent nursing bed and method for urination and defecation that integrates vacuum negative pressure collection, in-situ crushing, and deodorization and sterilization. Background Technology
[0002] Nursing beds are generally powered beds, which can be divided into electric or manual nursing beds. They are designed with multiple nursing functions according to the bedridden living habits and treatment needs of patients or the elderly. They are mainly used for the rehabilitation and nursing care of patients and are mainly used in hospitals, nursing homes and homes.
[0003] Bowel and bladder care for long-term bedridden disabled patients (such as critically ill patients, paraplegics, and elderly patients) presents a significant challenge in medical and home care. Traditional methods rely on manual handling, wiping, and changing bedpans or diapers, which have the following problems: extremely heavy nursing burden, requiring frequent and physically demanding procedures; poor patient dignity and comfort, with skin maceration and pressure sores caused by body exposure and prolonged contact with soiled areas; high hygiene and infection risks, as open handling can easily lead to ward environmental contamination and cross-infection; and difficulty in controlling odors, affecting patient psychology and the ward environment.
[0004] Traditional methods for managing patients' bowel and bladder functions include: bedpans or urinal pads, but these require manual operation and post-procedure care; some electric nursing beds only have lifting and turning functions, failing to address the issue of automatic waste disposal; some flushing nursing beds require complex water systems, which can lead to leaks, incomplete flushing, and the need to handle large amounts of wastewater, and cannot remove solid feces immediately; vacuum sewage technology (such as airplane toilets) uses direct suction, which may cause discomfort for bedridden patients, and lacks integrated, miniaturized, and in-situ treatment designs for bedridden settings, making it unsuitable for hospital bed use. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to overcome the defects of the prior art, such as heavy nursing burden, high risk of hygiene and dry infection, and difficulty in controlling odor, and to provide an intelligent nursing bed and method for urination and defecation that integrates vacuum negative pressure collection, in-situ crushing and deodorization and sterilization.

[0075] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.
[0076] Figures 1 to 14 The diagram shown is a structural schematic of an embodiment of the intelligent nursing bed and method for urination and defecation that integrates vacuum negative pressure collection, in-situ crushing, and deodorization and sterilization according to the present invention.
[0077] A smart nursing bed for urination and defecation that integrates vacuum negative pressure collection, in-situ crushing and deodorization and sterilization includes a bed structure, which includes an upper bed body 1 and a lower support frame 2 distributed vertically. The bed structure also includes guardrails, support legs and other support and functional modules.
[0078] An opening and closing unit is installed on the upper bed body 1. The upper bed body 1 has a drain port. The opening and closing unit is used to open and close the drain port.
[0079] The negative pressure collection unit is located below the discharge port and installed on the top of the lower support frame 2 to collect the patient's urine and feces under negative pressure.
[0080] The in-situ processing unit is located at the negative pressure collection unit and is used to perform in-situ crushing of the collected urine and feces.
[0081] The collection and storage unit is connected to the in-situ processing unit and is used to collect and store the waste after processing.
[0082] The cleaning and drying unit is connected to the negative pressure collection unit and is used to clean and dry the negative pressure collection unit.
[0083] The upper bed body 1 includes a bed board support and a mattress structure.
[0084] In this technical solution, the patient's excrement is collected directly under negative pressure through a negative pressure collection unit, which greatly reduces the physical labor of nursing staff and the frequency of direct contact with waste. Immediately after the patient excretes, the waste is crushed and deodorized in a closed negative pressure collection unit to prevent the spread of odor and environmental pollution. The cleaning and drying unit cleans and dries the parts that come into contact with the excrement, which greatly improves the hygiene level of the ward.
[0085] Furthermore, the negative pressure collection unit uses a two-stage negative pressure suction when collecting urine and feces to avoid strong suction causing discomfort to the patient.
[0086] At the same time, patients do not need to be moved when defecating, achieving "bedtime defecation," protecting privacy, keeping skin dry and clean, reducing the risk of infection, enhancing patient dignity, and improving patient comfort.
[0087] The opening and closing unit includes a blocking component 3, which is installed at the discharge port of the upper bed 1. The blocking component 3 is connected to the actuator end of the sliding component 4, which is installed at the bottom of the upper bed 1.
[0088] In this technical solution, the opening and closing of the discharge port of the upper bed 1 is controlled by the opening and closing unit. After sensing the discharge command, the sliding component 4 controls the blocking component 3 to move and open the discharge port of the upper bed 1. After the discharge and treatment operations are completed, the sliding component 4 controls the blocking component 3 to block the discharge port of the upper bed 1.
[0089] It is worth noting that the defecation command is manually controlled by the opening and closing unit. That is, after the patient feels the urge to defecate, he or she controls the opening and closing of the unit himself, or the staff opens and closes the unit according to the patient's defecation cycle.
[0090] The excretion command can also be automatically sensed, that is, excretion sensing sensors such as humidity, temperature, and gas sensors are installed in the upper bed body 1 to trigger the excretion command and control the system.
[0091] The sealing assembly 3 includes a sealing plate 31 and a flexible pad 32. The flexible pad 32 is disposed above the sealing plate 31, and the sealing plate 31 and the flexible pad 32 are connected by an inflatable airbag 33.
[0092] Furthermore, the inflatable airbag 33 is connected to one end of the telescopic connecting tube 35, and the other end of the telescopic connecting tube 35 is connected to the output end of the airbag air source 34, which is installed on the airbag.
[0093] In this technical solution, the discharge port of the upper bed body 1 is blocked and opened by the blocking component 3.
[0094] The side of the blocking plate 31 is connected to the execution end of the sliding assembly 4. The sliding assembly 4 includes a mounting housing 41, which is connected to the bottom of the upper bed body 1.
[0095] A sliding power source 42 is installed at the bottom of the housing 41. The output end of the sliding power source 42 is connected to a central gear 43. Actuating gears 44 are meshed on both sides of the central gear 43. The side of the actuating gear 44 meshes with a moving rack 45. One end of the moving rack 45 is connected to the side of the sealing plate 31.
[0096] In this technical solution, the sealing component 3 is moved by the sliding component 4, so that the sealing component 3 can block or open the discharge port of the upper bed body 1.
[0097] Furthermore, the movable rack 45 has a movable opening, and the inner wall of the bottom surface of the mounting housing 41 is connected to an anti-deviation rail 46, which is slidably connected to the movable rack 45 through the movable opening.
[0098] According to the opening command, the gas in the inflatable airbag 33 is first extracted using the airbag air source 34 and the telescopic connecting pipe 35, so that the inflatable airbag 33 is compressed. At this time, the flexible pad 32 is moved down, so that the flexible pad 32 is close to the sealing plate 31 and moves downward away from the discharge port of the upper bed body 1.
[0099] Then, the sliding power source 42 drives the central gear 43 to rotate, which in turn drives the execution gears 44 on both sides to rotate, which in turn drives the moving rack 45 to move. When the moving rack 45 moves, it drives the sealing plate 31 to move in the same direction, which in turn drives the flexible pad 32 and the inflatable airbag 33 and other structures to move in the same direction, so that the sealing plate 31 and other structures move away from the drain port of the upper bed body 1 in the horizontal direction, exposing the drain port of the upper bed body 1. At this time, the patient can perform defecation.
[0100] After the entire defecation process is completed, the sealing plate 31 and flexible pad 32 are moved in the opposite direction to the outlet of the upper bed 1. Then, the airbag 33 is inflated by the air source 34 and the telescopic connecting tube 35, causing it to expand and move the flexible pad 32 up and down to fill the outlet of the upper bed 1, so that the upper surface of the flexible pad 32 is flush with the upper surface of the upper bed 1, making the patient more comfortable when using the nursing bed.
[0101] The negative pressure collection unit includes a processing frame 5, which is installed on the top of the upper bed 1. One side of the processing frame 5 is connected to the negative pressure funnel group 6. The top opening of the negative pressure funnel group 6 is located directly below the discharge port of the upper bed 1. The bottom of the negative pressure funnel group 6 is connected to the execution end of the lifting assembly 7, which is installed on the top of the lower support frame 2.
[0102] In this technical solution, the patient's urine and feces are collected under negative pressure using a negative pressure collection unit.
[0103] The negative pressure funnel group 6 includes a collecting funnel 61 and an inner sealing ring 62. The inner sealing ring 62 is connected to the inner wall of the collecting funnel 61, and a flexible sealing ring 63 is connected to the upper end of both the collecting funnel 61 and the inner sealing ring 62.
[0104] The bottom of the collecting funnel 61 is connected to a conveying pipe 64, and the end of the conveying pipe 64 away from the collecting funnel 61 is connected to the top of the processing frame 5.
[0105] The collecting funnel 61 and the inner closed ring 62 are connected to the negative pressure generator 65 through a section of pipe 66, and the processing frame 5 is connected to the negative pressure generator 65 through two sections of pipe 67.
[0106] Specifically, a section of pipe 66 has two connectors at the end furthest from the negative pressure generator 65. One connector is connected to the space between the collecting funnel 61 and the inner closed ring 62, and the other connector is connected to the space inside the inner closed ring 62.
[0107] In this technical solution, the negative pressure funnel group 6 performs two stages of negative pressure suction on the patient's urine and feces. The first stage is low negative pressure, which forms a gentle seal and guides the patient to defecate and guides the urine and feces into the inner closed ring 62. The second stage is high negative pressure, which can suction the urine and feces in the collection funnel 61 into the processing frame 5.
[0108] When in use, the flexible sealing ring 63 at the collecting funnel 61 contacts and adheres tightly to the bottom of the upper bed body 1, and the flexible sealing ring 63 at the inner sealing ring 62 contacts and adheres tightly to the patient's buttocks, thus achieving a seal from both sides, ensuring the sealing effect and increasing the fault tolerance rate.
[0109] Then the negative pressure generator 65 works. At this time, one section of the pipeline 66 is opened and the two sections of the pipeline 67 are closed. The negative pressure is generated in the collection funnel 61 and the inner closed ring 62 by the one section of the pipeline 66. This is a low negative pressure. The patient's urine and feces are gently guided into the lower space inside the collection funnel 61 by the low negative pressure, which facilitates the patient's defecation operation.
[0110] Then, section 66 is closed and section 67 is opened. At this time, the working negative pressure is high. The urine and feces collected in the collection funnel 61 can be sucked into the treatment frame 5 through the delivery pipe 64 to avoid the large initial negative pressure causing a large impact on the patient and avoid patient discomfort.
[0111] The bottom of the collecting funnel 61 is connected to the execution end of the lifting assembly 7. The lifting assembly 7 includes a lifting plate 71, and a plurality of lifting connecting columns 72 are connected to the top of the lifting plate 71. The top of the lifting connecting columns 72 is connected to the bottom of the collecting funnel 61.
[0112] The bottom of the lifting plate 71 is connected to the output end of the lifting power source 73, which is installed on the top of the lower support frame 2.
[0113] Furthermore, multiple anti-deviation components are provided between the bottom of the lifting plate 71 and the top of the lower support frame 2. The anti-deviation components consist of two sliding columns 74 and a fixed sleeve 75 that are slidably connected to each other. The end of the sliding column 74 away from the fixed sleeve 75 is connected to the bottom of the lifting plate 71, and the end of the fixed sleeve 75 away from the sliding column 74 is connected to the top of the lower support frame 2.
[0114] In this technical solution, the height of the negative pressure funnel group 6 is adjusted by the lifting component 7 so that the negative pressure funnel group 6 is close to the discharge port of the upper bed body 1.
[0115] In use, the lifting power source 73 drives the lifting plate 71 to move up or down. When the lifting plate 71 moves, it drives the sliding column 74 and the lifting connecting column 72 to move in the same direction. When the lifting connecting column 72 moves, it drives the collecting funnel 61 to move in the same direction, thereby adjusting the height of the collecting funnel 61 so that the collecting funnel 61 can be closer to or further away from the discharge port of the upper bed body 1.
[0116] When the sliding column 74 moves, it moves along the fixed sleeve 75, and the sliding column 74 and the fixed sleeve 75 are used to limit the movement trajectory of structures such as the lifting plate 71.
[0117] The in-situ treatment unit includes a crushing component 8 and a deodorizing component 9, both of which are located at the treatment frame 5.
[0118] The crushing assembly 8 includes a rotating shaft 81. Four rotating shafts 81 arranged in a rectangular structure are provided in the inner cavity of the processing frame 5. All rotating shafts 81 are connected to the synchronous drive component for transmission. Multiple crushing blades 82 are connected to the surface of the rotating shaft 81.
[0119] Furthermore, the synchronous drive component is installed at the protective housing 83, and the protective housing 83 is connected to the top of the processing frame 5;
[0120] The synchronous drive component includes a synchronous power source 84, which is installed on the top of the processing frame 5. The output end of the synchronous power source 84 is connected to a drive gear 85. Both sides of the drive gear 85 are meshed with transmission gears 86. The transmission gears 86 are meshed with driven gears 87. One side of the driven gear 87 is connected to one end of the transmission shaft 88, and the other end of the transmission shaft 88 is rotatably connected to the inner wall of the protective housing 83.
[0121] Two bevel gear transmission parts 89 are connected to the surface of the transmission shaft 88, and the bevel gear transmission parts 89 are connected to the top end of the rotating shaft 81.
[0122] Specifically, the bevel gear transmission unit 89 consists of two meshing bevel gears, one of which is connected to the transmission shaft 88, and the other is connected to one end of the rotating shaft 81.
[0123] The deodorization component 9 includes a spray head 91, which is installed on the inner wall of the top surface of the treatment frame 5. The spray head 91 is connected to the outlet end of the spray pump 92, and the inlet end of the spray pump 92 is connected to the liquid storage tank 93.
[0124] Specifically, the spray pump 92 is installed on the top of the treatment frame 5, and the liquid storage tank 93 is installed on the top of the protective housing 83.
[0125] Furthermore, a synchronous power source 84 is installed on the top surface of the treatment frame 5, and a multi-layer deodorizing adsorption plate 95 is provided inside the synchronous power source 84 to adsorb and remove the odor emitted from the treatment frame 5.
[0126] In addition, ultraviolet lamps or ozone generators are installed at 91 spray nozzles to sterilize the broken-up feces and urine immediately.
[0127] In this technical solution, the excrement inside the treatment frame 5 is crushed and deodorized by the in-situ treatment unit.
[0128] When in use, when the two urination devices enter the processing frame 5, the synchronous power source 84 drives the drive gear 85 to rotate, which in turn drives the transmission gear 86 to rotate, which in turn drives the driven gear 87 to rotate. When the driven gear 87 rotates, it drives the transmission shaft 88 to rotate, which in turn drives the bevel gear transmission part 89 to rotate. When the bevel gear transmission part 89 rotates, it drives the rotating shaft 81 to rotate.
[0129] When the rotating shaft 81 rotates, it drives the crushing cutter 82 to rotate, and the rotating crushing cutter 82 is used to crush the two parts.
[0130] The surfaces of the rotating shaft 81 and the crushing blade 82 are made of corrosion-resistant material. The crushing blade 82 is used to crush solid feces into fine particles to form a slurry.
[0131] During crushing, the deodorant in the storage tank 93 is pumped into the spray nozzle 91 by the spray pump 92, and then sprayed onto the toilet through the spray nozzle 91 to eliminate odors at the source.
[0132] When it is necessary to release pressure from the treatment frame 5, the pressure release valve pipe 94 is opened. At this time, the gas is adsorbed by the deodorization adsorption plate 95 and then discharged into the external environment, further achieving deodorization treatment.
[0133] The storage unit includes a storage component 10, which includes a collection valve pipe 101 and a liquid valve pipe 103. The collection valve pipe 101 is connected to the lower part of the processing frame 5, and the liquid valve pipe 103 is connected to the side of the processing frame 5.
[0134] The end of the collection valve pipe 101 away from the processing frame 5 is detachably connected to the collection box 102, and the end of the liquid valve pipe 103 away from the processing frame 5 is detachably connected to the collection cylinder 104.
[0135] Specifically, the connection between the collecting valve pipe 101 and the collecting box 102, and between the liquid valve pipe 103 and the collecting cylinder 104, can be achieved by means of threads, etc.
[0136] It should be noted that the connection position between the liquid valve pipe 103 and the treatment frame 5 is higher than the connection position between the collection valve pipe 101 and the treatment frame 5. In actual use, when the dirt in the treatment frame 5 is still, a rough sedimentation can be carried out. At this time, the supernatant enters the collection cylinder 104 through the liquid valve pipe 103 for collection, and the heavier dirt at the bottom enters the collection box 102 through the collection valve pipe 101 for collection.
[0137] In this technical solution, the storage component 10 collects the waste processed by the processing frame 5.
[0138] The cleaning and drying unit includes a cleaning component 11 and a drying component 12. The cleaning component 11 includes a water tank 111, which is installed on the top of the lower support frame 2. A cleaning pump 112 is installed on the top of the water tank 111. The inlet end of the cleaning pump 112 is connected to the water tank 111, and the outlet end of the cleaning pump 112 is connected to a cleaning pipe 113. The end of the cleaning pipe 113 away from the cleaning pump 112 is connected to the side of the collection funnel 61. The collection funnel 61 and the inner closed ring 62 are provided with multiple rinsing ports, and all of the multiple rinsing ports are connected to the cleaning pipe 113.
[0139] The drying assembly 12 includes a drying fan 121, which is installed on the top of the water tank 111. The inlet end of the drying fan 121 is connected to the filter heating box 122, which is also installed on the top of the water tank 111. The outlet end of the drying fan 121 is connected to an inlet pipe 123. The end of the inlet pipe 123 away from the filter heating box 122 is connected to the side of the collection funnel 61. The collection funnel 61 and the inner closed ring 62 are provided with multiple air blowing ports, all of which are connected to the inlet pipe 123.
[0140] Specifically, the filter heating box 122 achieves airflow filtration and heating through a filter screen and a heater.
[0141] When in use, the flushing liquid in the water tank 111 is first pumped into the cleaning pipe 113 by the cleaning pump 112, and then the collection funnel 61, the inner closed ring 62 and other pipes in contact with the toilet are cleaned through multiple cleaning ports.
[0142] After cleaning, the filtered and heated airflow is sent into the inlet pipe 123 by the drying fan 121, and blown through multiple air ports to the collection funnel 61, the inner closed ring 62 and other pipes that come into contact with the toilet for drying.
[0143] Both are used to achieve self-cleaning of the collection channel, keeping the collection channel dry and hygienic, ready for the next use.
[0144] It is worth noting that a heating device can be placed in the water tank 111 to control the water temperature during rinsing.
[0145] In addition, the entire nursing bed is equipped with an intelligent control system, which includes a central controller, a human-machine interface, and a network module.
[0146] The central controller is responsible for coordinating the sequential operation of all modules, namely sensing, opening the lid, docking, negative pressure collection, crushing, disinfection, sterilization and deodorization, self-cleaning, etc.
[0147] The human-computer interaction interface is a touch screen or remote control, which allows users or caregivers to manually start, set modes, and view status.
[0148] The networking module is used to upload device status and nursing records to the cloud.
[0149] The nursing care method includes the following steps:
[0150] S1. Sensing and preparation: Confirming the occurrence or imminent occurrence of excretion through manual or sensor commands. At this time, the opening and closing unit operates to open the excretion port of the upper bed 1. Then, the negative pressure collection unit rises to the excretion port and seals the connection.
