Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to an intelligent remote control system for indwelling urinary catheters after spinal surgery. Background Art

[0002] Spinal cord injuries are usually accompanied by spinal cord or cauda equina nerve injuries. The symptoms of this disease can cause dysuria, leading to symptoms such as urinary incontinence in patients. At the same time, it may also be accompanied by lower limb paralysis, which will seriously reduce the quality of life of patients. Therefore, indwelling urinary catheters are often used in critically ill patients with spinal trauma and after spinal surgery.

[0003] The urination mechanism of spinal cord injury patients is relatively complex, and spinal cord injuries at different locations will cause different types of neurogenic bladder. Existing technologies have developed bladder care methods that evaluate bladder volume through bladder pressure and then use urinary catheters to assist patients in intermittent catheterization to empty the bladder. Shen Hongmei et al. explored the application value of bladder pressure volume measurement in the bladder function rehabilitation of high-level spinal cord injury patients in the article "The Application Value of Bladder Pressure Volume Measurement in the Bladder Rehabilitation of High-level Spinal Cord Injury Patients". In this article, the correlation between bladder pressure volume and urodynamics was explored, and it was confirmed that urodynamic examination or bladder pressure detection can be used as indicators to reflect the urination ability of patients.

[0004] The results of urine volume detection can indirectly reflect the hemodynamic state of the body, directly reflect renal function and renal perfusion. Renal perfusion can comprehensively reflect the clinical status of hemodynamics, blood volume, cardiac function and blood vessels. At the same time, abnormal urine volume often indicates that the body has diseases in clinical practice, and the clinical significance of urine volume needs to be judged according to different situations.

[0005] Regarding the existing technologies for urine volume detection and adjustment, a urine monitoring device for non-invasive extracorporeal circulation surgery disclosed in Chinese Patent No. CN104116516A includes a urine dropper and a urinary catheter connected to its lower end; a drip rate sensor for measuring the drip rate of urine and a red light sensor for measuring the hemoglobin content in urine are sequentially arranged on the urinary catheter. The drip rate sensor and the red light sensor are respectively connected to a microprocessor, and the microprocessor is connected to a monitoring device. This device can statically observe urine volume and urine color. Or a hydration treatment device disclosed in Chinese Patent No. CN116173346A. The device includes a housing, on which a main control module and a peristaltic pump are installed. The peristaltic pump is electrically connected to the main control module; a support rod is fixedly connected inside the housing, and weighing sensors are fixedly connected to both sides of the support rod. A hook is fixedly connected to the weighing end of the weighing sensor; a liquid replenishment cylinder, a urine storage cylinder, a balance tank, a liquid storage cylinder and a waste liquid bucket are installed inside the housing.

[0006] However, in the prior art, there is no solution for assisting doctors in judging how to balance urine volume and fluid infusion volume based on the real-time physiological state of patients during the postoperative or rehabilitation care process, so as to ensure that patients can achieve normal urine excretion during the postoperative or rehabilitation care process, especially the oral intake required by patients at different rehabilitation stages that cannot be grasped by the patient guardians.

[0007] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, when the applicant made this invention, a large number of documents and patents were studied, but all the details and content were not listed in detail due to space limitations. However, this does not mean that this invention does not possess the features of these prior arts. On the contrary, this invention already possesses all the features of the prior arts, and the applicant reserves the right to add relevant prior arts in the background art. Summary of the Invention

[0008] In the prior art, indwelling catheters are manually operated. It is not easy for spinal surgery patients to control them by themselves, and often their escorts need to operate for them; for severely injured spinal trauma patients who are bedridden for a long time, the traditional indwelling catheters are manually operated, and the patients have no self-control ability to urinate. When accidents occur, such as when the escort forgets, the patients are at risk of overdistension of the bladder or even catheter-related urinary tract infections; because the traditional indwelling catheters adopt manual control of urination or no control of urination, for critically ill patients who need to monitor urine volume, such devices cannot accurately determine the bladder pressure and the urine output. Due to problems such as the cultural level or cognitive bias of the escorts, they cannot accurately judge the time of clamping the catheter to release urine and record the urine output, thus delaying the treatment of the patients.

[0009] To accurately balance the relationship between a patient's water intake and the catheterization control process, existing technologies have emerged that combine a diet management device with a catheterization management device to jointly control the relationship between the water content of a patient's food intake and catheterization parameters. For example, patent publication number CN112569414A discloses a diet and catheterization management system and its control method. The diet and catheterization management system includes a diet management device and a catheterization management device. The diet management device includes a weighing component, a first sensing component connected to the weighing component, and a display. The first sensing component is used to identify the type of food consumed by the patient, the weighing component is used to weigh the food, and the display is used to display the water content of the food. The catheterization management device includes a catheterization management component, which is used to catheterize the patient and detect the patient's catheterization volume and residual urine volume. The diet and catheterization management system of this technical solution accurately measures the water content of the patient's food intake and, based on this water content, accurately determines the next catheterization time, thereby facilitating the patient's health recovery. However, this technical solution aims to detect the actual water content of the patient's food intake and use this as a control basis for adjusting catheterization parameters. The amount of water consumed by the patient does not directly participate in the control process of urine drainage. Therefore, even if the catheterization parameters in this technical solution change due to the water content of the patient's food intake, its adjustment control logic is still limited to focusing on the control parameters related to catheterization, and does not combine the patient's active or passive adjustment of water intake to control the parameters related to the catheterization process. This regulation method is still detrimental to the patient's health. For example, if the patient has excessive water intake through food, the measure taken by this technical solution is to increase the number of catheterizations or the amount of urine per catheterization, which is not conducive to the patient's recovery of autonomous urination control function.

[0010] This application provides an intelligent remote control system for indwelling urinary catheters after spinal surgery, comprising: a urine control module that switches control status based on detected bladder pressure; and a physician-side program connected to a hospital management cloud and capable of regulating the urine control module's automatic control of the patient's urination behavior. This application also relates to an intelligent remote control system for indwelling urinary catheters.

[0011] When the urine volume detected by the urine control module exceeds the range preset by the doctor's side, the hospital management cloud obtains the patient's actual total fluid replacement volume based on the oral intake volume related to the patient's food intake and the patient's injection volume generated by the data transmitted by the oral intake detection module, and generates a program for selectively adjusting the patient's injection volume and / or oral intake volume by comparing the patient's actual total fluid replacement volume with the preset total fluid replacement volume, wherein the adjustment of the injection volume is evaluated and authorized by the doctor's side based on the data related to the patient's urine volume fed back by the hospital management cloud; the adjustment of the oral intake volume is evaluated and authorized by the doctor's side based on the data related to the patient's eating senses fed back by the patient's personal control terminal.

[0012] Different from the prior art, the doctor's end in the present invention can communicate with the hospital management cloud and can adjust the urine control module to automatically control the patient's urination behavior program. When the urine volume detected by the urine control module is abnormal compared with the preset reference value at the doctor's end, the hospital management cloud of the present invention can generate a program for selectively adjusting the injection volume and / or oral intake of the patient based on different associated data according to the detected total fluid intake of the patient. Based on the above different technical features, the problems to be solved by the present invention may include: how to adjust the active and passive water intake according to the real-time change of the urine volume discharged by the patient, so that the urine volume discharged by the patient can meet the preset index. Specifically, the beneficial effects of the present technical solution:

[0013] The urine control module of the present application is provided with a bladder pressure detection component and a urethral catheter opening and closing component. Through the dual detection of the excretion of urine volume and the pressure value representing the urine volume in the bladder, the automatic control of the patient's urination is realized.

[0014] The system of the present application is respectively provided with two control methods, namely automatic and manual, and the control state is switched in real time based on the patient's urination state.

[0015] Compared with the urine detection system involved in the prior art, the system involved in the present application takes the urine volume as the judgment benchmark to adjust and consider the patient's intake (including oral intake and injection volume) and the patient's urine production speed. Urination control - urine volume detection - intake control is a cycle that restricts each other. The present system realizes the control of the patient's postoperative kidney state by incorporating each factor in the cycle into the monitoring range and setting intelligent benchmarks for the conditions of each factor, rather than simply urination control.

[0016] According to a preferred embodiment, when the bladder pressure collected by the bladder pressure detection component of the urine control module is lower than the preset first threshold for a time exceeding the preset range or the urine volume of the patient collected by the urine volume detection component of the urine control module is lower than the preset threshold, the hospital management cloud respectively obtains the injection volume and oral intake of the patient, and selectively adjusts the injection volume and / or oral intake of the patient based on the physiological data of the patient feedback by the physiological detection module under the authorization of the doctor's end.

[0017] The beneficial effects of the present technical solution:

[0018] Different from the prior art, the present application further makes a further division of the adjustment of the two main factors in the fluid replacement volume, that is, the oral intake and the injection volume. Taking the patient's urine storage capacity (or the muscle capacity of the detrusor muscle) as the judgment benchmark, through the control of medical staff, the actual method of considering increasing the fluid replacement volume is adopted, rather than simply thinking that when the urine is less, the fluid replacement volume is increased.

[0019] According to a preferred embodiment, the system is further provided with an oral intake detection module placed in the same space as the patient to collect the oral intake of the food entering the patient's mouth when the patient eats. Among them, the hospital management cloud generates the oral intake data corresponding to the food based on the weight characteristics and images of the food collected by the oral intake detection module.

[0020] According to a preferred embodiment, the total fluid infusion volume includes the injection volume generated based on the injection solution in the doctor's order sent by the doctor side and stored in the hospital management cloud, and the oral intake confirmed by the patient through the oral intake detection module or the personal control terminal.

[0021] According to a preferred embodiment, when the urine volume detected by the urine control module is lower than the minimum endpoint value of the range preset by the doctor side, and the fluid infusion volume including the patient's injection volume and oral intake obtained by the hospital management cloud is also lower than the minimum endpoint value of the range preset by the doctor side, the hospital management cloud generates a prompt program to increase the patient's oral intake based on the patient's rehabilitation progress feedback by the doctor side or a program to increase the patient's injection volume under the authorization of the doctor side.

[0022] According to a preferred embodiment, when the doctor's order related to the patient's rehabilitation progress feedback is in the rehabilitation state at the initial stage of the operation when eating is not allowed after the operation, the hospital management cloud generates a program to increase the patient's injection volume under the authorization of the doctor side based on the patient's rehabilitation progress feedback by the doctor side.

[0023] According to a preferred embodiment, the urine control module is configured as follows:

[0024] When the bladder pressure is lower than the preset first threshold or higher than the second threshold, the urine control module is provided with a program to control the patient's urination as the first priority. The program includes an intelligent switch of the urine catheter opening and closing component of the urine control module based on the bladder pressure collected by the bladder pressure detection component of the urine control module. The intelligent switch of the urine catheter opening and closing component can be to generate an instruction to switch the urine catheter opening and closing component by the system based on a preset standard.

[0025] According to a preferred embodiment, the urine control module is configured as follows:

[0026] When the bladder pressure is within the range with the first threshold and the second threshold as critical points, the program for controlling the patient's urination with the manual switching of the urethral catheter opening and closing component of the urine control module by the patient through the personal control terminal is taken as the first priority. Different from the prior art, the urine control module of the present invention can adjust the urination control method of the program for controlling the patient's urination with the first priority when the bladder pressure collected by the bladder pressure detection component of the urine control module is within different preset ranges. Based on the above distinguishing technical features, the problems to be solved by the present invention may include: how to adjust the program for controlling the patient's urination according to the real-time bladder pressure collected by the bladder pressure detection component of the urine control module, so as to perform corresponding training on the urination reflex ability during the postoperative rehabilitation process of the patient, and further improve the patient's ability to independently control the urination process. Specifically, for example, when the bladder pressure of the patient is higher than the set second threshold, in order to prevent the problem of urinary retention in the patient's bladder that may cause urethral infection, especially for patients with over-tight detrusor or low urination reflex perception, the present invention can set the urethral catheter opening and closing component to an automatically opened control mode, so that the urine in the patient's bladder can be discharged in time; or when the bladder pressure of the patient is lower than the set first threshold, in order to achieve the purpose of postoperative detrusor muscle exercise, especially for patients with relaxed detrusor or sensitive urination reflex, at this time, even if the patient chooses to manually open the urethral catheter opening and closing component, the urethral catheter opening and closing component remains in the closed state, so as to realize switching the corresponding urethral catheter state according to the actual state of the detected bladder pressure, and improve the matching degree of the urination process and the urination ability currently possessed by the patient.

[0027] According to a preferred embodiment, the urine control module includes a back plate and a urine volume detection component arranged on the back plate for detecting and hanging the urine volume in the urine bag hanging on the back plate. The urine bag is hung on the back plate through a hook arranged on the back plate.

[0028] The beneficial effects of this technical solution:

[0029] Prior art methods for measuring urine volume often involve placing a sensor on a urine bag or inserting and removing a catheter from an integrated urine volume measurement container. Considering the former's increased weight and the risk of catheter dislodgement, and the latter's problem of loosening the distal opening of the catheter and reducing its seal due to repeated insertion and removal (since the catheter is inserted into the body, it is generally not replaced until the patient has completely lost control of passive urination), this application addresses the need for catheter opening and closing control and urine volume measurement, providing a device that allows patients to adjust the position of their urine bag under different conditions. When patients need to get out of bed or move around, or otherwise find it inconvenient to carry the device, given that this process is often brief, they can detach the device and hang the urine bag on their body, avoiding the effects of repeated rubbing of the catheter against the urethra caused by the device. When the patient is stationary (e.g., bedridden), they can simply reattach the urine bag to the device. The device is simple to operate, inexpensive, and reusable (it avoids direct contact with patient bodily fluids, reducing the difficulty of disinfection). Even when promoting the device, it can be integrated with the system described in this application and deployed in wards with demand.

[0030] According to a preferred embodiment, the doctor uses the patient's circadian rhythm to program the conditions for the urine control module to switch the urinary catheter state when in the automatic control program.

[0031] Beneficial effects of this technical solution:

[0032] The patient's urination behavior and urine volume are often used as important indicators to assess the patient's renal function risk and postoperative recovery status. However, the existing technology for urine volume assessment relies on manual observation of the residual volume in the bag. Due to the uncertain update time of the bag and the large error in the bag's volume measurement, medical staff have no way to detect some short-term postoperative sequelae that can be detected early through urine volume, resulting in the sequelae being discovered only after they have worsened. On the other hand, with the increase in the aging population and the younger age of diseases, many historical diseases that affect renal function will also frequently appear in hospitalized patients. The existing technology for urine volume assessment is often based on the assessment of people with a normal baseline and ignores the impact of historical diseases on renal function. The impact of the patient's urine volume. At the same time, due to work restrictions, medical staff can neither go to the ward rhythmically to check the patient's urine volume nor pay attention to the patient's 24-hour diet. The error in assessing the patient's physical condition by irregularly testing the patient's urine volume is huge. For example: due to frequent dry mouth the day before, the patient was fed a large amount of high-water content food by the guardian that day and produced more urine than the previous day; or the urine volume of patients with a history of nephrotic syndrome will be less than that of normal people (because the patient's bed label card does not indicate the historical disease, this part of the content often requires the doctor to retrieve the database to understand it, and the high-frequency urine volume check before this is very likely to overlook this factor).

Detailed implementation manners

[0040] The following will be described in detail with reference to the accompanying drawings.

[0041] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, terms such as "configured to", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal communication of two components. The meaning of "several" is two or more, unless otherwise clearly specifically limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0042] Severely injured patients with spinal trauma and those after spinal surgery will have an indwelling urinary catheter to help them urinate. During spinal surgery, after the urinary catheter is indwelling for 48 hours before or during the operation, due to reasons such as anesthesia, body position, psychology, surgery, and individual differences, patients will become dependent on the urinary catheter during the indwelling period and be affected by factors such as urethral irritation, resulting in difficulty in urination even after the urinary catheter is removed postoperatively, thus causing the phenomenon of urinary retention. In particular, after general anesthesia, the recovery speed of bladder nerves is relatively slow, and the contractility of the detrusor muscle of the bladder weakens. Even though the urination reflex is affected by the urinary catheter, there will still be difficulty in urination and the problem of urinary retention. It is reported that the incidence of postoperative urinary retention is 2.3 - 75.0%. Postoperative urinary retention can lead to bladder weakness, increase the risk of urinary tract infection and sepsis, cause overdistension and damage of the detrusor muscle, ultimately prolong the hospital stay, and increase medical costs. To prevent the occurrence of urinary retention, clamping tube training makes the bladder empty and fill regularly, exercising the bladder function, which is considered an effective measure to prevent the occurrence of urinary retention after catheter removal.

[0043] Therefore, exercising the contractility of the detrusor muscle by controlling bladder pressure through urination is a method to help patients quickly recover the bladder urination reflex ability postoperatively. Embodiment 1

[0044] This embodiment provides a fluid infusion monitoring system. This embodiment provides a body fluid balance detection system. This embodiment provides a fluid infusion prompt system based on in - vivo and in - vitro urine volume detection data.

[0045] Figure 1 The functional structure diagram of this system is shown. In this application, the physiological detection module 600, urine control module 100, personal control terminal 500, oral intake detection module 200, doctor's terminal 400, and hospital management cloud 300 can establish communication connections (such as data, signals, and / or control signals, etc.) through a wireless network (such as Bluetooth, WIFI, NFC, infrared technology, etc.).

[0046] This application relates to a urine monitoring module on the one hand. The urine control module 100 includes a main body 110, a backplane 1101 connected to the main body 110, a urine volume detection component 1104 for detecting the urine volume in the urine bag 700 hanging on the backplane 1101, and a urinary catheter opening and closing component 1105 for wrapping the urinary catheter 710 and provided on the backplane 1101. In this application, considering that the patient may need to get out of bed or move around, the urine control module 100 and the urine bag 700 are separated, and the urine bag 700 is provided with a bladder pressure detection component 720. The bladder pressure detection component 720 includes a balloon 7201 and a bladder pressure sensor 7202. The structural setting of the urine bag 700 refers to the structural setting of the urine bag 700 for bladder pressure detection in the prior art. Figure 2The figure shows a disposable urine bag 700 used in the current working environment of the inventor. An inlet connected to a urinary catheter 710 and an outlet for emptying the urine in the urine bag 700 are respectively provided at both ends of the urine bag 700. The Y-shaped pipeline of the urinary catheter 710 is divided into three parts: a sub-pipeline for pressure detection, a diversion sub-pipeline inserted into the bladder, and a main pipeline where the two sub-pipelines converge and are connected to the inlet of the urine bag 700. A medical Luer taper is installed at the proximal end of the sub-pipeline for pressure detection and is connected to the pressure sensing joint of the bladder pressure sensor 7202. As Figure 2 shown, the bladder pressure sensor 7202 is provided at the proximal end of the sub-pipeline for pressure detection of the urinary catheter 710. A balloon 7201 is installed at the proximal end of the diversion sub-pipeline inserted into the bladder. Medical staff inflate the proximal end of the sub-pipeline for pressure detection through the medical Luer taper, and the gas flows through the diversion sub-pipeline inserted into the bladder to the balloon 7201 communicated with it, so that the balloon 7201 arranged in the bladder is clamped therein to prevent the urinary catheter 710 from slipping out of the bladder.

[0047] Specifically, the surface of the main body 110 facing the patient is divided into two parts by the display screen 1102 and the back plate 1101, as Figure 2 shown. Preferably, the back plate 1101 is integrally provided with the main body 110. A hook 1103, a urinary catheter opening and closing component 1105 and a urine volume detection component 1104 are provided on the back plate 1101. The hook 1103 is used for hanging the urine bag 700, so that the urine bag 700 hangs on the back plate 1101 based on gravity. The urine volume detection component 1104 is arranged on the back plate 1101 along the first direction, for example, arranged in parallel with the urine bag 700. One end of the urine bag 700 is provided with an opening connected to the urinary catheter 710, and a liquid stop valve is provided at the opening at the other end. Preferably, the urine volume detection component 1104 can be an optical liquid level sensor, for example, the liquid level is detected by an infrared sensor. The first direction is the extending direction of the back plate 1101.

[0048] The urinary catheter 710 is buckled at the position of the urinary catheter opening and closing component 1105. Specifically, the urinary catheter 710 is arranged as a Y-shaped pipeline, and the pipelines of its two branches are respectively connected to the balloon 7201 and the bladder pressure sensor 7202. When the main pipeline is controlled by the urinary catheter opening and closing component 1105 and is in a closed state, the pipelines of the two branches are in a communicating state, and the pressure detected by the pressure sensor is the bladder and urethra pressure. The pressure sensor transmits the detected pressure value to the main body 110 and generates corresponding bladder pressure data.

[0049] In use, a pipeline with a balloon 7201 at one end is inserted into the patient's bladder. The balloon 7201 is made of medical-grade materials, such as silicone or other soft and biocompatible polymers. After the balloon 7201 is inserted into the bladder, normal saline or other sterile solutions are injected into the balloon 7201 through an external pipeline to make it expand until a predetermined pressure or volume is reached. The balloon 7201 is clamped inside the patient's bladder, so that the urine inside the bladder can only flow out through the urinary catheter 710.

[0050] A pressure sensor is provided at the other end of the urinary catheter 710 of the Y-shaped pipeline. Since the distal end of the urinary catheter 710 is connected to the sealed bag, and the end with the balloon 7201 is substantially connected to both the bladder and the end with the pressure sensor, when the urine stored in the bladder changes, the pressure sensor can sense the pressure change inside the bladder. Preferably, the pressure sensor can be a micro piezoelectric sensor, a capacitive sensor or other types of pressure sensors. The pressure sensor detects and converts the pressure change into an electrical signal. These signals are then transmitted to an external monitoring device (such as the hospital management cloud 300), so that the bladder pressure of the patient can be recorded and analyzed. Preferably, the bladder pressure sensor 7202 can include a wireless data transmission function to ensure its ability to transmit data to the hospital management cloud 300 in real time. In addition, the pressure sensor can be integrated with a battery or powered by wireless energy transmission technology to reduce the number of maintenance times and improve patient comfort.

[0051] As Figure 4 shown, in the actual use process, when the patient lies in bed, the height of the urine bag 700 shall not be higher than the height of the patient's perineum to avoid urine reflux and infection. However, due to the different requirements of the patient for the height of the hospital bed after surgery, such as the height of the perineum of the supine and prone patients from the ground, the main body 110 involved in this application is provided with a support rod with adjustable height. When the urine bag 700 is hung on the back plate 1101, by adjusting the height of the main body 110, the urine bag 700 can always be lower than the height of the patient's perineum.

[0052] The display screen 1102 can display the real-time urine volume, the preset urine volume transmitted by the doctor terminal 400 or the hospital management cloud 300, the fluid replacement volume transmitted by the hospital management cloud 300, and the evaluation result of whether the current patient's oral intake is healthy. In order to facilitate the patient's guardian to obtain a prompt for the patient's oral intake of liquid through the difference between the real-time urine volume and the preset urine volume, the display screen 1102 is provided with the above basic data.

[0053] On the one hand, this application relates to a physiological detection module 600 wirelessly connected to the hospital management cloud 300. The physiological detection module 600 can be any monitoring device matched to the patient in the current hospital. For example: The physiological detection module 600 is configured as a monitor, a wearable medical device, etc.

[0054] On the other hand, this application relates to an oral intake detection module 200 that is placed in the same space as the patient to collect the oral intake of the food entering the patient's mouth when the patient eats.

[0055] Preferably, the oral intake detection module 200 can be integrated into a bedside table dedicated to the ward in the patient's ward, such as Figure 4 As shown, the tabletop of the bedside table dedicated to the ward is provided with a weight acquisition component that can be manually switched on and off and a camera 210 for acquiring the image of the tabletop. The patient's guardian can place the food to be ingested by the patient on the tabletop and turn on the switch. The oral intake detection module 200 can transmit the collected weight and image data of the food to the hospital management cloud 300. The hospital management cloud 300 performs a similarity comparison based on the images stored in its database to confirm the type of food, and generates the corresponding liquid oral intake characteristics in combination with the weight data.

[0056] Preferably, the oral intake detection module 200 can be a medical device independently set in the ward, such as Figure 3 As shown. The oral intake detection module 200 includes a weighing component, a camera 210 disposed on the weighing component, and an identity recognition component disposed inside the housing 220 of the weighing component. The identity recognition component can be related components for the patient and his or her guardian to identify the patient's identity by swiping a card, fingerprinting, etc. The weighing component includes a housing 220, a weight sensor, and a communication part with information transmission function. The communication part and the weight sensor are disposed inside the housing 220. The camera 210 faces the gravity sensing area 230 disposed on the surface of the housing 220 of the gravity sensor to acquire an image of the food when the relevant food is placed on the gravity sensing area 230. The communication part sends the data collected by the gravity sensor and the camera 210 to the hospital management cloud 300. The hospital management cloud 300 converts the oral intake corresponding to the food.

[0057] Taking the food conversion formula stored in the hospital cloud in the prior art as an example (there are certain errors in the water content of the same food measured by different water content measurement methods):

[0058] 1. Classified according to water content, among which, the water content of water, tea, beverages, and fresh milk is 100%; the water content of porridge, soup, tofu, fresh vegetables, and fruits is 90%; the water content of yogurt, ice cream, and thick porridge is 80%; the water content of rice, potatoes, fresh fish and shrimp, meat, eggs, dried tofu, and pancake is 70%; the water content of steamed buns, cakes, bread, baked buns, noodles, various cooked meats, vermicelli, dried bean curd sticks, pastries, and dried goods (cooked food) is 30%.

[0059] Taking this as the standard, when the food is the staple food (rice) with a weight of 0.1 kg, based on the relevant conversion formula stored in the database of the hospital management cloud 300, the hospital management cloud 300 learns that the oral intake of the patient is 0.07 kg.

[0060] 2. If according to the corresponding ratio of food and water volume shown in Table 2, when the food is watermelon with a weight of 0.5 kg, based on the relevant conversion formula stored in the database of the hospital management cloud 300, the hospital management cloud 300 learns that the oral intake of the patient is 0.395 kg.

[0061] The doctor terminal 400 and the patient's personal control terminal 500 in this application can be set as mobile intelligent devices, such as: mobile phones, controllers, PCs, medical PDAs, etc.

[0062] The urine control module 100 can switch the control state under the influence of the detected bladder pressure. The urine control module 100 provided with the bladder pressure detection component 720 switches to the state with manual control as the first priority or the state with intelligent switch as the first priority based on the collected bladder pressure data.

[0063] According to a preferred embodiment, when the bladder pressure collected by the bladder pressure detection component 720 of the urine control module 100 is lower than the preset first threshold or higher than the second threshold, the urine control module 100 is provided with a program for controlling the patient to urinate as the first priority. The program includes intelligent switching of the urinary catheter opening and closing component 1105 of the urine control module 100 based on the bladder pressure collected by the bladder pressure detection component 720 of the urine control module 100. The intelligent switching of the urinary catheter opening and closing component 1105 can be to generate corresponding instructions for switching the urinary catheter opening and closing component 1105 by the system based on the preset standard. Specifically, when the patient's bladder pressure is higher than the second threshold, for patients with over-tight detrusor or low sensitivity of the micturition reflex, in order to prevent the problem of urinary retention in the patient's bladder that may cause urethral infection, the urinary catheter opening and closing component 1105 automatically opens, so that the urine in the patient's bladder can be discharged in time; when the patient's bladder pressure is lower than the first threshold, for patients with relaxed detrusor or sensitive micturition reflex, in order to achieve the purpose of postoperative detrusor muscle exercise, even if the patient chooses to manually open the urinary catheter opening and closing component 1105, the urinary catheter opening and closing component 1105 remains in the closed state.

[0064] According to a preferred embodiment, when the doctor's terminal 400 feedbacks that the doctor's order related to the patient's rehabilitation progress is in the rehabilitation state at the initial stage of the operation when eating is not allowed after the operation, the hospital management cloud 300 generates a program to increase the patient's injection volume with the authorization of the doctor's terminal 400 based on the patient's rehabilitation progress feedbacked by the doctor's terminal 400. Preferably, the patient's rehabilitation progress feedbacked by the doctor's terminal 400 includes: the patient is in the rehabilitation state at the initial stage of the operation when eating is not allowed after the operation, and increasing the patient's injection volume is used as a means to increase the patient's fluid infusion volume; the patient is in the rehabilitation state at the middle stage of the operation when taking liquid food, and increasing the patient's injection volume is used as a means to increase the patient's fluid infusion volume; the patient is in the rehabilitation state at the end stage of the operation when having normal diet after the operation, and increasing the patient's injection volume is used as a means to increase the patient's fluid infusion volume.

[0065] According to a preferred embodiment, when the bladder pressure is within the range with the first threshold and the second threshold as the critical points, a program for controlling the patient's urination with the manual switch of the urinary catheter opening and closing component 1105 of the urine control module 100 by the patient through the personal control terminal 500 as the first priority. When the bladder is in a normal state (the pressure is within the range with the first threshold and the second threshold as the critical points), the detrusor has been exercised, and affected by the difference in the patient's personal perception, the patient will generate a reaction to urinate in combination with their own state when the bladder is at different pressure values, and this reaction is beneficial to the exercise of the urination reflex in the patient's postoperative rehabilitation process, that is, the patient consciously chooses to urinate in a reasonable bladder state. Therefore, in this situation, the urinary catheter opening and closing component 1105 is opened or closed under manual influence.

[0066] According to a preferred embodiment, the first threshold and the second threshold can be adjusted in the urine control module 100 under the instruction sent by the hospital management cloud 300 according to the change in urine volume. The behavior of forced urination or forced urine retention needs to be managed in combination with the patient's urine volume on the same day or at that time. Based on the information about the patient's recovery process sent by the doctor terminal 400 (the doctor updates the patient's status through the doctor terminal 400 by means such as ward rounds), the hospital management cloud 300 can generate the first threshold and the second threshold in combination with the patient's real-time urine volume, and send the judgment criteria related to the first threshold and the second threshold to the urine control module 100. For example: For patients in the initial stage of surgery, the occurrence of urination behavior and the achievement of a reasonable urine volume are more important for medical staff to timely detect the patient's physical problems. Therefore, the first threshold generated by the hospital management cloud 300 when the patient's real-time urine volume is 0 is the smallest value among the multiple first thresholds given by the doctor terminal 400; when the hospital management cloud 300 modifies the patient's recovery process to the end stage of surgery and / or the patient's real-time urine volume reaches 1500 mL (the urine volume of a normal person is about 1500-2000 mL) based on the information about the patient's recovery process sent by the doctor terminal 400, the hospital management cloud 300 can increase the value of the first threshold. Preferably, for each additional stage of the patient's recovery process (for example: changing from the initial stage of surgery to the middle stage of surgery; the urine volume increases by 500 mL), the first threshold can increase by a preset gradient value.

[0067] According to a preferred embodiment, the doctor terminal 400 plans the conditions for the urine control module 100 to switch the state of the urinary catheter 710 when it is in the automatic control program according to the patient's circadian rhythm. Under the condition that the patient's urine volume and recovery process are determined, the patient's disease and historical urination data can be used to evaluate the conditions for switching the state of the urinary catheter 710 when the patient is in the waking state and the drowsy state. When the patient is in the drowsy state, due to the lack of conditions for manually switching the state of the urinary catheter 710, the urinary catheter opening and closing component 1105 of the urine control module 100 can use the urination frequency in the patient's historical urination data stored in the database of the hospital management cloud 300 as the frequency for automatically opening the urinary catheter 710, and when the bladder pressure is higher than the second threshold, the urinary catheter opening and closing component 1105 of the urine control module 100 automatically opens the urinary catheter 710. When the patient is in the waking state, the urinary catheter opening and closing component 1105 of the urine control module 100 can switch the state of the urinary catheter 710 based on the above-mentioned "affected by the detected bladder pressure" method.

[0068] The doctor's terminal 400 held by the medical staff in charge of the patient is communicatively connected to the hospital management cloud 300. The doctor's terminal 400 held by the medical staff in charge of the patient can, based on the physiological indicators fed back by the physiological detection module 600, adjust the program for automatically controlling the urination behavior of the patient so that the bladder pressure is lower than the first threshold or higher than the second threshold by opening or closing the urinary catheter 710 when the patient is awake, in the case of changes in the patient's rehabilitation process, total fluid infusion volume, or physical condition. Preferably, the hospital management cloud 300 can be an HIS system.

[0069] According to a preferred embodiment, the hospital management cloud 300 generates oral intake data corresponding to the food based on the weight characteristics and images of the food collected by the oral intake detection module 200. The total fluid infusion volume includes the injection volume generated based on the injection solution in the doctor's order issued by the doctor's terminal 400 and stored in the hospital management cloud 300, and the oral intake based on the oral intake confirmed by the patient through the oral intake detection module 200 or the personal control terminal 500.

[0070] As Figure 5 shown, when the urine volume detected by the urine control module 100 exceeds the range preset by the doctor's terminal 400, the hospital management cloud 300 generates a program for selectively adjusting the patient's injection volume and / or oral intake based on the total fluid infusion volume of the patient obtained from the patient detection module.

[0071] As Figure 5 shown, when the time during which the bladder pressure collected by the bladder pressure detection component 720 of the urine control module 100 is lower than the preset first threshold exceeds the preset range, or when the urine volume of the patient collected by the urine volume detection component 1104 of the urine control module 100 is lower than the preset threshold, the hospital management cloud 300 respectively obtains the patient's injection volume and oral intake, and selectively adjusts the patient's injection volume and / or oral intake based on the physiological data of the patient fed back by the physiological detection module under the authorization of the doctor's terminal 400.

[0072] As Figure 5 shown, when the urine volume detected by the urine control module 100 is lower than the minimum endpoint value of the range preset by the doctor's terminal 400, and the fluid infusion volume including the patient's injection volume and oral intake obtained by the hospital management cloud 300 is also lower than the minimum endpoint value of the range preset by the doctor's terminal 400, the hospital management cloud 300 generates a program for prompting to increase the patient's oral intake based on the patient's rehabilitation process fed back by the doctor's terminal 400 or a program for increasing the patient's injection volume under the authorization of the doctor's terminal 400.

[0073] Specifically, when the urine volume U detected by the urine control module 100 is lower than the minimum endpoint value V of the range preset by the doctor's terminal 400 minWhen the fluid replacement volume R obtained by the hospital management cloud 300, which includes the injection volume and oral intake volume of the patient, is also lower than the minimum endpoint value P preset at the doctor's end, the hospital management cloud 300 generates a prompt program to increase the patient's oral intake or a program to increase the patient's injection volume with the authorization of the doctor's end based on the patient's recovery progress fed back by the doctor's end 400, which can be expressed as:

[0074] When U < V min And R < P, execute f(T) (1)

[0075] Where f(T) is a program generated according to the patient's recovery progress T.

[0076] In this program, the hospital management cloud can preset the patient's recovery progress, for example, divided into three stages. The doctor's end can feed back to the hospital management cloud when there is a change in the patient's recovery progress.

[0077] According to a preferred embodiment, when the medical advice related to the patient's recovery progress fed back by the doctor's end is in the recovery state at the initial stage of the operation when the patient cannot eat after the operation, the hospital management cloud generates a program to increase the patient's injection volume with the authorization of the doctor's end based on the patient's recovery progress fed back by the doctor's end, which can be expressed as:

[0078] g(M) (2)

[0079] Where g(M) is a program generated for the medical advice M.

[0080] In this program, the program generated for the medical advice M can be manually input and confirmed by medical staff or automatically generated and confirmed based on an experience table. The table can be as shown in Table 1 below, and medical staff pre-generate the following table based on their own experience.

[0081]

[0082] The configuration of the urine control module can be expressed by the following formula:

[0083]

[0084] Where B is the bladder pressure, and θ1 and θ2 are preset first and second thresholds.

[0085] The problem to be solved by the present invention, that is, to adjust the program for controlling the patient's urination according to the real-time bladder pressure B collected by the bladder pressure detection component of the urine control module, can be expressed as:

[0086]

[0087] Based on the detection of the above real-time bladder pressure to adjust the urination mechanism can achieve the purpose of enhancing the patient's autonomous control ability.

[0088] According to a preferred embodiment, the urine volume detection component 1104 of the urine control module 100 detects the urine volume in the urine bag 700 in real time. The doctor's terminal 400 held by the medical staff responsible for the patient sends the patient's rehabilitation progress to the hospital management cloud 300. When the urine volume collected by the urine volume detection component 1104 of the urine control module 100 exceeds the range preset by the doctor's terminal 400 and the doctor's terminal 400 that receives the data sent by the physiological detection module confirms that the patient has no accident (the confirmation information of the doctor's terminal 400 confirming no accident is sent to the hospital management cloud 300 after the medical staff inputs the confirmation information through the doctor's terminal 400), the hospital management cloud 300 promotes the increase of urine volume for the patient in the initial stage of the operation by increasing the injection volume (so as to increase the total fluid infusion volume). When the urine volume collected by the urine volume detection component 1104 of the urine control module 100 exceeds the range preset by the doctor's terminal 400 and the doctor's terminal 400 that receives the data sent by the physiological detection module confirms that the patient has no accident, the hospital management cloud 300 promotes the increase of urine volume for the patient in the terminal stage of the operation by increasing the oral intake volume (so as to increase the total fluid infusion volume). When the urine volume collected by the urine volume detection component 1104 of the urine control module 100 exceeds the range preset by the doctor's terminal 400 and the doctor's terminal 400 that receives the data sent by the physiological detection module confirms that the patient has no accident, the hospital management cloud 300 promotes the increase of urine volume for the patient in the middle stage of the operation by increasing the oral intake volume / injection volume (so as to increase the total fluid infusion volume).

[0089] The adjustment of the injection volume is evaluated and authorized by the doctor's terminal 400 based on the data related to the patient's urine volume feedback by the hospital management cloud 300; the adjustment of the oral intake volume is evaluated and authorized by the doctor's terminal 400 based on the data related to the patient's eating senses feedback by the patient's personal control terminal 500. Specifically, for patients in the middle stage of surgery who can eat normally but may have postoperative reactions, through the feedback of the eating senses information (for example: the patient selects "can increase the food volume" from "can increase the food volume" and "cannot increase the food volume" through the personal control terminal 500 to the hospital management cloud 300 (or the medical staff feedback to the hospital management cloud 300 through the doctor's terminal 400 during the ward round), the hospital management cloud 300 can selectively adjust the oral intake volume / injection volume. For example: when the patient sends the feedback information of "cannot increase the food volume" to the hospital management cloud 300 through the personal control terminal 500, the hospital management cloud 300 can increase the injection volume (for example: increase the injection volume of 2 bottles of normal saline) with the authorization of the doctor's terminal 400, or when the patient sends the feedback information of "can increase the food volume" to the hospital management cloud 300 through the personal control terminal 500, the hospital management cloud 300 can increase the oral intake volume and injection volume with the authorization of the doctor's terminal 400 (for example: based on the data related to the oral intake volume transmitted by the oral intake volume detection module 200, when the patient's single-day oral intake volume is less than 1000 mL, the hospital management cloud 300 calculates the difference in the patient's oral intake volume and prompts the patient to drink the water of the calculated difference). Preferably, the balance between the total fluid infusion volume and the urine volume is set in advance by the medical staff through the doctor's terminal 400 in the hospital management cloud 300. For example: the total fluid infusion volume being more than 0.8 times the urine volume indicates that the patient's total fluid infusion volume is normal.

[0090]

[0091] Specifically, the total amount of raw materials for processed food in Table 2 refers to the weight of the main raw materials for preparing the food, such as rice, flour, eggs, meat (oil, water, or seasonings used in the processing process are not included in the weight calculation). For example: when the processed food is rice, the water content of 50 g of raw rice after cooking is 80 g. When the processed food is rice porridge, the water content of 50 g of raw rice in the cooked rice porridge is 400 g. The water content of 250 g of soaked soybeans after being prepared into soy milk is 230 g. The water content of 100 g of raw noodles after cooking into a small amount of noodles with soup is 200 g.
