Description

Technical Field

[0001] This invention relates to the field of bed technology specifically for nursing care, and more particularly to an intelligent nursing bed with a bathing function. Background Technology

[0002] Showering is the best way for humans to cleanse their skin and maintain cleanliness and comfort. However, critically ill patients and those in a vegetative state who are bedridden for extended periods must be moved to a bathtub or tub in the bathroom for bathing. This transfer process generally requires at least two people, either by carrying the patient directly or using specialized lifting and transfer equipment. This is not only strenuous but also poses numerous safety hazards. The workload is heavy, causing fatigue for nursing staff, especially in the difficult task of maintaining the patient's personal hygiene.

[0003] For example, Chinese patent CN111616896A discloses a nursing bed with a shower function. By setting a lifting platform on the bed frame, and installing a waterproof zippered waterproof sheet and a removable cotton sheet on the lifting platform, the nursing bed can provide a place for patients to sleep normally in daily life. When it is necessary to bathe, shower, or wipe the patient's body, the cotton sheet can be removed, and then the lifting platform can be raised by the lifting component. A cavity is formed between the lifting platform and the bed frame. Due to the patient's weight, the middle of the zippered waterproof sheet will be recessed, thus forming a water storage level to achieve the effect of showering. However, neglecting the adjustment of the soaking depth will result in the entire nursing bed being bulky and huge.

[0004] In addition, the existing technology has the following shortcomings:

[0005] 1. In traditional nursing procedures, patients need to be moved from their nursing bed to the bathroom or special bathing facilities by caregivers when taking a bath, which may cause discomfort or even injury to the patient.

[0006] 2. Existing nursing shower processes typically lack automated turning modules, requiring caregivers to operate them manually, which is time-consuming and prone to inaccuracies, easily resulting in the shower and washing areas not being fully displayed.

[0007] 3. In traditional nursing care, caregivers need to manually assist patients with bathing and cleaning, which is not only physically demanding but also prone to causing discomfort to patients. Especially for patients who are bedridden for a long time, frequent manual repositioning may lead to muscle damage or other complications.

[0008] This invention was made to address the common problems in the field of nursing beds, such as limited functionality, poor manual shower adjustment capabilities, lack of shower position adjustment, low patient comfort, non-adjustable soaking depth, and low level of intelligence. Summary of the Invention

[0009] The purpose of this invention is to address the shortcomings of current methods by proposing an intelligent nursing bed with a bathing function.

[0010] To overcome the shortcomings of the prior art, the present invention adopts the following technical solution:

[0011] A smart nursing bed with a bathing function includes a server and a nursing bed. The smart nursing bed also includes a position adjustment module, a support deformation module, and a water tank shower module. The server is connected to the position adjustment module, the support deformation module, and the water tank shower module respectively.

[0012] The nursing bed is equipped with a shower tank with one end open. The water tank shower module, the position adjustment module and the support deformation module are respectively set in the shower tank. The water tank shower module showers the user who falls into the shower tank, the position adjustment module adjusts the user's showering posture, and the support deformation module adjusts the user's showering depth.

[0013] The support deformation module includes a support deformation unit, a deformation analysis unit, and a height feedback unit. The height feedback unit provides feedback on the adjusted height of the support deformation unit. The deformation analysis unit analyzes the deformation of the support deformation unit based on the adjustment height set by the operator to generate an analysis result. The support deformation unit adjusts the shower height of the user based on the analysis result.

[0014] Optionally, the supporting deformation unit includes a water storage pad, a supporting airbag, an air supply pipe, a supporting plate, an air pump, an electronic air release valve, and a pressure sensor. The water storage pad is nested in the shower tub, and the bottom wall of the shower tub is provided with a storage cavity. The air pump is connected to the supporting airbag through an air supply pipe to form a supporting part. The supporting part is disposed in the storage cavity. The supporting plate is disposed on the supporting airbag to form a raised part. The raised part is disposed under the water storage pad and is disposed opposite to the opening direction of the shower tub.

[0015] Optionally, the position adjustment module includes a position adjustment unit and a pull detection unit. The position adjustment unit adjusts the user's shower posture, and the pull detection unit collects the pull amount that pulls on the position adjustment unit.

[0016] The position adjustment unit includes an adjustment belt, an adjustment rod, an adjustment drive mechanism, and an adjustment cavity. One end of the adjustment rod is driven to be connected to the adjustment drive mechanism to form an adjustment part. The adjustment cavity is disposed on both sides of one end of the shower tank. The adjustment parts are symmetrically disposed in the adjustment cavity and the one end of the adjustment rod is hinged to the side wall of the adjustment cavity to form a hinge part. The adjustment drive mechanism drives the adjustment rod to rotate along the axis of the hinge part.

[0017] The two ends of the adjustment belt are respectively connected to the adjustment rods on both sides of the shower tank.

[0018] Optionally, the deformation analysis unit obtains the adjustment height set by the operator and calculates the inflation volume Q according to the following formula:

[0019]

[0020] In the formula, H 设定 The target height set by the operator, H 当前 H represents the current height of the support unit. 差 The height difference is equal to H. 差 =H 设定 -H 当前 ΔH is the difference between the previous and current heights, representing the feedback amount of historical adjustments; dH / dt is the rate of height change; and Times is the system's set reaction time.

[0021] The deformation analysis unit transmits the calculated inflation volume Q to the support deformation unit and triggers the support deformation unit to adjust the shower height of the user.

[0022] Optionally, the water tank shower module includes a sliding plate, a shower unit, a traction unit, and a folding unit. The sliding plate is disposed at one end of the shower tank and extends toward the center of the shower tank to form a sliding part. The folding unit is disposed on the bed board of the nursing bed and communicates with the shower tank. The traction unit assists in pulling the user and slowly pulls the user into the shower tank. The shower unit is disposed in the shower tank and sprays shower water into the shower tank.

[0023] Optionally, the folding unit includes a folding plate, an auxiliary rod, and an auxiliary drive mechanism. The folding plate is hinged to the two side walls of the shower tub. One end of the auxiliary rod is driven to the auxiliary drive mechanism to form an auxiliary part. The other end of the auxiliary rod is hinged to one side face of the folding plate facing the shower tub. The auxiliary part is disposed on the side wall of the shower tub and is hinged to the side wall of the shower tub.

[0024] Optionally, the traction unit includes a traction belt, a traction seat, a traction rod, and a traction drive mechanism. The traction seat is provided with an actuation cavity. One end of the traction rod is drivenly connected to the traction drive mechanism to form a traction part. The traction part is disposed in the actuation cavity. The other end of the traction rod is hinged to the side wall of the actuation cavity to form an actuation part. The traction belt is disposed on the traction rod and is wound on the traction rod.

[0025] The traction seat is located at the head of the nursing bed and is arranged in the same direction as the sliding plate.

[0026] The beneficial effects achieved by this invention are:

[0027] 1. Through the combination of the position adjustment module and the support deformation module, users can freely adjust their bathing posture and soaking depth according to their personal needs, accurately adjust the patient's bathing angle and posture, and ensure that each patient can bathe in the most comfortable posture, thereby maximizing the comfort of care.

[0028] 2. By combining the support deformation module with the water tank shower module, the shower depth can be precisely adjusted according to the patient's body shape and needs, avoiding the defect of the non-adjustable soaking depth in traditional nursing beds, thus providing a personalized water bath care plan and ensuring that the soaking effect reaches the best care state.

[0029] 3. By combining the position adjustment module with the water tank shower module, the nursing bed can intelligently adjust the water level and water flow direction according to the patient's condition and needs, reducing the intervention and operation of nursing staff, thereby improving the automation and intelligence of nursing care and avoiding the tedious process of manual adjustment in traditional beds.

[0030] 4. By combining the support deformation module with the water tank shower module, the system ensures that patients receive comprehensive support and safety during soaking or bathing, avoiding falls or physical discomfort caused by improper soaking depth or unstable position, thus improving patient safety.

[0045] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of the present invention. Furthermore, the accompanying drawings of the present invention are for simple illustrative purposes only and are not depictions of actual dimensions; this is stated beforehand. The following embodiments will further describe the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention.

[0046] Example 1: According to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, this embodiment provides an intelligent nursing bed 1 with a bathing function. The intelligent nursing bed 1 includes a server and a nursing bed 1. The intelligent nursing bed 1 also includes a position adjustment module, a support deformation module, and a water tank shower module. The server is connected to the position adjustment module, the support deformation module, and the water tank shower module respectively, and stores the intermediate data and process data of the position adjustment module, the support deformation module, and the water tank shower module in the server for querying and retrieval.

[0047] The nursing bed 1 is provided with a shower tank 4 with one end open. The water tank shower module, the position adjustment module and the support deformation module are respectively arranged in the shower tank 4. The water tank shower module showers the user who falls into the shower tank 4. The position adjustment module adjusts the user's showering posture and the support deformation module adjusts the user's showering depth.

[0048] The intelligent nursing bed 1 also includes a central processing unit, which is connected to the position adjustment module, the support deformation module, and the water tank shower module. The central processing unit centrally controls the position adjustment module, the support deformation module, and the water tank shower module to improve the overall nursing bed 1's ability to provide refined care and reliability for the user.

[0049] Optionally, the water tank shower module includes a sliding plate 3, a shower unit, a traction unit, and a folding unit. The sliding plate 3 is disposed at one end of the shower tank 4 and extends toward the middle of the shower tank 4 to form a sliding part. The folding unit is disposed on the bed board of the nursing bed 1 and communicates with the shower tank 4. The traction unit assists in pulling the user and slowly pulls the user into the shower tank 4. Specifically, the traction unit assists in pulling the user onto the position adjustment module. The shower unit is disposed in the shower tank 4 and sprays shower water into the shower tank 4.

[0050] Optionally, the folding unit includes a folding plate 2, an auxiliary rod 5, and an auxiliary drive mechanism. The folding plate 2 is hinged to the two side walls of the shower tank 4. One end of the auxiliary rod 5 is driven to the auxiliary drive mechanism to form an auxiliary part. The other end of the auxiliary rod 5 is hinged to one side face of the folding plate 2 facing the shower tank 4. The auxiliary part is disposed on the side wall of the shower tank 4 and is hinged to the side wall of the shower tank 4.

[0051] like Figure 11 or Figure 12As shown, the sides of the auxiliary rod 5, the shower tank 4, and the folding plate 2 form a stable triangular structure.

[0052] When the auxiliary drive mechanism drives the auxiliary rod 5, the auxiliary rod 5 extends and retracts, causing the folding plate 2 to rotate along the hinge position. This causes the folding plate 2 to slowly open and place the user in the shower tank 4, thereby achieving the purpose of showering.

[0053] When the folding plate 2 is opened, the user slowly immerses himself into the shower tank 4 along the sliding plate 3. At the same time, due to the inclined surface of the sliding plate 3, the user comes into contact with the inclined end face of the sliding plate 3, thereby immersing himself into the shower tank 4.

[0054] In this embodiment, water can be placed in the shower trough in advance, or the user can take a shower through the shower unit after entering the shower trough 4.

[0055] Meanwhile, during the process of the user entering the shower tub 4, the traction unit can be used to assist traction as needed to prevent excessive impact from the user entering the shower tub 4 and causing new injuries, while also improving the safety and reliability of care.

[0056] Optionally, the traction unit includes a traction belt 15, a traction seat 12, a traction rod, and a traction drive mechanism. The traction seat 12 is provided with an action cavity. One end of the traction rod is drivenly connected to the traction drive mechanism to form a traction part. The traction part is disposed in the action cavity. The other end of the traction rod is hinged to the side wall of the action cavity to form an action part. The traction belt 15 is disposed on the traction rod and is wound on the traction rod.

[0057] The traction seat 12 is located at the head of the nursing bed 1 and is arranged in the same direction as the sliding plate 3.

[0058] The traction unit also includes a control handle for operation by nursing or medical personnel. The control handle is equipped with a control button, which is electrically connected to the traction drive mechanism. When the control button is triggered, the traction drive mechanism can be controlled.

[0059] When assistance is needed for the user, the caregiver wraps the traction strap around the user's armpit and operates the control handle to drive the traction drive mechanism to rotate the traction rod, thereby slowly lowering the user into the shower tank 4.

[0060] In addition, a cushioning material is provided on the contact surface between the traction belt 15 and the user. The cushioning material reduces the traction force of the traction belt 15 on the user and improves the user's comfort.

[0061] The shower unit includes a shower head 21, a shower pipe 18, a cold water supply pipe 20, a hot water supply pipe 22, a control valve, a hot water tank 10, a water storage tank 9, a supply pump 13, a suction pump 14, and a heating element disposed in the hot water tank 10. The control valve has a first inlet, a second inlet, and an outlet. The water storage tank 9 is used to store cold shower water. The supply pump 13 is disposed at one end of the hot water supply pipe 22 to form a supply section, which is disposed in the hot water tank 10 and supplies hot shower water from the hot water tank 10. The other end of the hot water supply pipe 22 is connected to the first inlet of the control valve. One end of the cold water supply valve is connected to the suction pump 14. The other end of the cold water supply pipe 20 is connected to the second inlet of the control valve. One end of the shower pipe 18 is connected to the outlet of the control valve, and the other end of the shower pipe 18 is connected to the shower head 21 to form a shower water supply passage.

[0062] The heating element is installed in the hot water tank 10 and heats the hot water in the hot water tank 10.

[0063] The heating component includes a heating element 11 and a current controller. The heating element 11 is disposed in the hot water tank 10 and heats the hot water in the hot water tank 10. The current controller is electrically connected to the heating element 11 to control the current passing through the heating element 11, thereby achieving precise control of the heat.

[0064] The shower unit further includes a control valve for adjusting the water flow rate of the shower pipe 18; the control valve is installed on the shower pipe 18 and controls the flow rate of the shower pipe 18.

[0065] When the user enters the shower tank 4, the support deformation module provides auxiliary support for the user's body and helps collect shower water.

[0066] In addition, the support deformation module includes a support deformation unit, a deformation analysis unit, and a height feedback unit. The height feedback unit provides feedback on the adjusted height of the support deformation unit. The deformation analysis unit analyzes the deformation amount of the support deformation unit based on the adjustment height set by the operator to form an analysis result. The support deformation unit adjusts the shower height of the user based on the analysis result.

[0067] The height feedback unit includes a control panel and a memory. The control panel is designed to be touch-sensitive and allows caregivers and operators to set the user's height adjustment. The memory stores the height adjustment data cached after the operator manipulates the control panel.

[0068] Optionally, the deformation analysis unit obtains the adjustment height set by the operator and calculates the inflation volume Q according to the following formula:

[0069]

[0070] In the formula, H 设定 The target height set by the operator, H 当前 The current height of the support unit is H, which is obtained by a height sensor installed on the support unit. 差 The height difference is equal to H. 差 =H 设定 -H 当前 ΔH is the difference between the previous and current heights, representing the feedback amount of historical adjustments; Times is the system's set reaction time; and dH / dt is the rate of height change.

[0071] The rate of change of altitude, dH / dt, is calculated according to the following formula:

[0072]

[0073] In the formula, H(t) is the actual bed height at the current time t, and H(t+Δt) is the target bed height at the target time t+Δt, or the target height adjusted according to the output of the control system.

[0074] The deformation analysis unit transmits the calculated inflation volume Q to the support deformation unit and triggers the support deformation unit to adjust the shower height of the user.

[0075] Optionally, the supporting deformation unit includes a water storage pad 6, a supporting airbag 8, an air supply pipe, a supporting plate 7, an air pump, an electronic air release valve, and a pressure sensor. The water storage pad is nested in the shower tank 4, and the bottom wall of the shower tank 4 is provided with a storage cavity. The air pump is connected to the supporting airbag 8 through an air supply pipe to form a supporting part. The supporting part is disposed in the storage cavity. The supporting plate 7 is disposed on the supporting airbag 8 to form a raised part. The raised part is disposed under the water storage pad 6 and is disposed opposite to the opening direction of the shower tank 4.

[0076] The water-retaining pad 6 is made of a wear-resistant plastic film and is placed in the shower tank 4 to collect water after showering;

[0077] In this embodiment, when the user is about to enter the shower tub 4, the padding part is inflated by the air pump to the support airbag 8, so that the support airbag 8 inflates and slowly supports the user, and assists the user in entering the shower tub 4;

[0078] At the same time, the inflation adjustment of the padding part can also enable the user's height position to be adjusted, thereby changing the depth of the user's immersion in the shower tank 4, improving the convenience and reliability of showering or cleaning.

[0079] By combining the support deformation module with the water tank shower module, the shower depth can be finely adjusted according to the patient's body shape and needs, avoiding the defect of the non-adjustable soaking depth in the traditional nursing bed 1, thus providing a personalized water bath care plan and ensuring that the soaking effect reaches the best care state.

[0080] By combining the support deformation module with the water tank shower module, the system ensures that patients receive comprehensive support and safety during soaking or bathing, avoiding falls or physical discomfort caused by improper soaking depth or unstable position, thus improving patient safety.

[0081] Optionally, the position adjustment module includes a position adjustment unit and a pull detection unit. The position adjustment unit adjusts the user's shower posture, and the pull detection unit collects the pull amount that pulls on the position adjustment unit.

[0082] The position adjustment unit includes an adjustment belt 17, an adjustment rod 16, an adjustment drive mechanism 19, and an adjustment cavity. One end of the adjustment rod 16 is driven to be connected to the adjustment drive mechanism 19 to form an adjustment part. The adjustment cavity is disposed on both sides of one end of the shower tank. The adjustment parts are symmetrically disposed in the adjustment cavity, such that one end of the adjustment rod 16 is hinged to the side wall of the adjustment cavity to form a hinge part. The adjustment drive mechanism 19 drives the adjustment rod 16 to rotate along the axis of the hinge part.

[0083] The two ends of the adjustment band 17 are respectively connected to the adjustment rods 16 on both sides of the shower tank 4.

[0084] In this embodiment, the two ends of the adjustment belt 17 are detachably connected to the rods of the adjustment rods 16 symmetrically arranged on both sides of the rain trough.

[0085] After the traction unit pulls the user onto the adjustment belt, the user can freely adjust the bathing posture and soaking depth according to their personal needs through the cooperation of the position adjustment module and the support deformation module. This allows for precise adjustment of the patient's bathing angle and posture, ensuring that each patient can bathe in the most comfortable posture and maximizing the comfort of care.

[0086] Meanwhile, the adjustment strap 17 is made of waterproof material and is a disposable item to prevent cross-infection.

[0087] The tension detection unit includes a tension rope and a tension sensor. The tension rope is hidden and woven into the adjustment belt 17 and connected to the tension sensor so that the tension rope is captured by the tension sensor during operation.

[0088] After the tension sensor collects the tension force, it feeds it back to the central processing unit, which then controls the adjustment drive mechanism 19 to drive the adjustment rod 16, thereby pulling the adjustment belt 17 and adjusting the user's posture.

[0089] In this embodiment, the adjustment drive mechanism 19's adjustment operation on the adjustment part effectively improves the adjustment of the shower posture, ensuring that the entire nursing bed 1 has a wide range of applicable scenarios.

[0090] By combining the position adjustment module with the water tank shower module, the nursing bed 1 can intelligently adjust the water level and water flow direction according to the patient's condition and needs, reducing the intervention and operation of nursing staff, thereby improving the automation and intelligence of nursing care and avoiding the tedious process of manual adjustment in traditional beds.

[0091] Through the coordinated operation of the position adjustment module, the support deformation module, and the water tank shower module, the nursing bed 1 can intelligently adjust its position, posture, depth, and water temperature with the assistance of nursing staff. This reduces the workload of nursing staff on patients during the bathing process and improves the efficiency of nursing work.

[0092] Example 2: This example should be understood as including all the features of any of the foregoing examples, and further improving upon them, according to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the intelligent nursing bed 1 also includes a temperature control module, which monitors the water temperature and air-drying temperature during the shower process, and evaluates the water temperature and air-drying temperature of the shower unit based on the user's personalized temperature data and the current supply water temperature to form an evaluation result, and adjusts the water temperature of the shower unit according to the evaluation result.

[0093] The temperature control module includes a temperature monitoring unit, a temperature analysis unit, a drying unit, and a water temperature control unit. The temperature monitoring unit collects the water temperature and drying temperature supplied during the shower process. The temperature analysis unit evaluates the water temperature and drying temperature of the shower unit based on the user's personalized temperature data and the current supply water temperature to form an evaluation result. The water temperature control unit adjusts the water temperature of the shower unit and the drying temperature of the drying unit based on the evaluation result.

[0094] The temperature monitoring unit includes an α temperature sensor, a β temperature sensor 27, and a data buffer. The α temperature sensor collects temperature data from at least two detection locations of the shower unit, the β temperature sensor 27 collects the air-drying temperature, and the data buffer stores the temperature data collected by the temperature sensors.

[0095] The α temperature sensor is set to detect locations including, but not limited to, the following: water outlet, water inlet, and on the water flow path.

[0096] Specifically, the temperature sensors are configured to be installed at the water outlet, water inlet, and water flow path, respectively, to monitor the water outlet, water inlet, and water flow path.

[0097] The temperature monitoring unit also includes a wind speed sensor 26, which is located at the air outlet of the air drying unit and collects the air flow rate at the air outlet.

[0098] The β temperature sensor 27 and the wind speed sensor 26 are both located at the air outlet of the air drying unit, and both are miniature sensors.

[0099] The temperature analysis unit acquires the user's personalized temperature data and the current supply water temperature relative to the shower unit's water temperature, and calculates the water temperature control index Worm according to the following formula:

[0100]

[0101] In the formula, T in T represents the inlet water temperature. out T represents the outlet water temperature. ref The target temperature set by the user, ΔT path The temperature difference along the water flow path is defined as: ΔT path =T out -T in ;k adjust The dynamic adjustment factor is set based on the user's temperature sensitivity and comfort level, with a range of [0,1], and is input by the operator from the human-computer interaction interface according to actual needs.

[0102] In this embodiment, the dynamic adjustment factor k adjust The value of this factor is directly related to the user's sensitivity to temperature changes. Different users have different tolerances for temperature changes; some may be very sensitive to temperature fluctuations and require the system to adjust rapidly, while others may be less sensitive to fluctuations. Example values ​​for the dynamic adjustment factor are provided below:

[0103] 1) Typical household user care scenario (in this scenario, the user's comfort requirements for water temperature are moderate)

[0104] Among these, the dynamic adjustment factor k is typically suitable for general household environments as it does not require particularly rapid temperature adjustments. adjust The value can be:

[0105] k adjust =0.3;

[0106] 2) Elderly care scenario (addressing the care needs of elderly users, who are typically very sensitive to fluctuations in water temperature);

[0107] Slight changes in water temperature can cause discomfort, especially during bathing. When elderly people use nursing beds, the system needs to adjust the water temperature more precisely, hence the need for a dynamic adjustment factor k. adjust The value can be:

[0108] k adjust =0.7;

[0109] 3) Postpartum care scenario (In the scenario of child bathing and care, changes in water temperature have a significant impact on the child's comfort and safety);

[0110] Among them, children have poor adaptability to water temperature, so a more precise temperature control system is needed to ensure water temperature stability, hence the need for a dynamic adjustment factor k. adjust The value can be:

[0111] k adjust =0.8;

[0112] 4) Severe patient care scenario (for the care of severe patients, the patients may be bedridden for a long time, have weak physical strength, and temperature changes may have an adverse effect on the patient's physical condition).

[0113] Among them, severely ill patients have poor thermoregulation and are easily affected by fluctuations in external temperature. Therefore, the temperature control system needs to react quickly to ensure that the water temperature is within a very precise range, avoiding drastic temperature fluctuations that could affect the patient.

[0114] Use a higher dynamic adjustment factor k adjust To enable the system to respond more quickly to water temperature fluctuations and meet the high comfort and safety requirements of severely ill patients, the dynamic adjustment factor k is used.adjust The value can be:

[0115] k adjust =0.9;

[0116] 5) Respiratory disease care scenario (For patients with respiratory diseases (such as asthma or difficulty breathing), changes in water temperature may worsen their condition, especially when there are large temperature fluctuations in the bathroom)

[0117] Patients with respiratory illnesses require a stable environment to prevent breathing problems caused by water temperature fluctuations. In this scenario, the temperature control system does not need an overly aggressive response, but rather a more stable adjustment of the water temperature; therefore, the dynamic adjustment factor k is crucial. adjust The value can be:

[0118] k adjust =0.5;

[0119] Meanwhile, medium k adjust =0.5 can balance the response sensitivity and stability of the temperature control system, ensuring that patients bathe in a comfortable water temperature environment.

[0135] 5) Patient care scenarios in high humidity environments (in environments with high humidity (such as tropical regions or indoor environments with high humidity in winter), patients may be less sensitive to wind speed, but high humidity may affect drying efficiency and require higher wind speed to accelerate moisture evaporation), then k = 2.0.

[0142] Postoperative patient care: k heat =1.0 (moderate response, stable air temperature);

[0143] High-efficiency drying requirements: k heat =1.2 (Fast response, slightly higher air temperature).

[0144] In summary, the thermal regulation coefficient k heat Configure the settings according to the actual situation and input them from the human-computer interaction interface.
