Description

[0001] The original basis of the divisional application is a patent application with the application number 202410692156.4, the application date of May 31, 2024, and the invention name of "Intelligent remote control system for indwelling urinary catheter after spinal surgery". TECHNICAL FIELD

[0002] The present application relates to the field of medical devices, and in particular to a fluid replacement monitoring system and method. BACKGROUND

[0003] Spinal injury is usually combined with spinal cord or cauda equina nerve injury, and the symptoms of the disease can cause urinary and fecal dysfunction, which can cause patients to have symptoms such as urinary incontinence, and can also be accompanied by lower extremity paralysis, which can seriously reduce the quality of life of patients. Therefore, patients with severe spinal trauma and patients after spinal surgery often have indwelling urinary catheters.

[0004] The urination mechanism of patients with spinal injury is relatively complex, and spinal injury at different positions can cause different types of neurogenic bladder. The existing technology has developed a bladder care method that uses bladder pressure to evaluate bladder volume and then uses a urinary catheter to assist patients in intermittent urinary bladder emptying. Shen Hongmei et al. discussed the application value of bladder pressure volume determination in the rehabilitation of bladder function in patients with high spinal cord injury in the article "Application Value of Bladder Pressure Volume Determination in Bladder Rehabilitation in Patients with High Spinal Cord Injury". In this article, the relationship between bladder pressure volume and urodynamic was explored, and it was confirmed that urodynamic examination or bladder pressure detection can be used as an indicator to reflect the patient's urination ability.

[0005] The results of urine volume detection can indirectly reflect the hemodynamic state of the body, directly reflect the renal function and renal perfusion, and the renal perfusion can comprehensively reflect the hemodynamic, blood volume, cardiac function and vascular clinical state. At the same time, urine volume abnormalities often indicate that the body has a disease, and the clinical significance of urine volume needs to be judged according to different situations.

[0006] Regarding existing technologies for urine volume detection and adjustment, Chinese Patent Publication No. CN104116516A discloses a urine monitoring device for non-invasive extracorporeal circulation surgery, comprising a urine dropper and a urine tubing connected to its lower end; a drip rate sensor for measuring the urine drip rate and a red light sensor for measuring the hemoglobin content in the urine are sequentially arranged on the urine tubing, and the drip rate sensor and the red light sensor are respectively connected to a microprocessor, which is connected to a monitoring device. This device can statically observe urine volume and urine color. Alternatively, a hydration therapy device disclosed in Chinese Patent Publication No. CN116173346A is also described. This device includes a housing, on which a main control module and a peristaltic pump are mounted, the peristaltic pump being electrically connected to the main control module; a support rod is fixedly connected inside the housing, with weighing sensors fixedly connected to both sides of the support rod, and hooks fixedly connected to the weighing ends of the weighing sensors; an infusion cylinder, a urine storage cylinder, a balance tank, a reservoir, and a waste liquid tank are installed inside the housing.

[0007] However, current technologies do not address the real-time physiological state of patients during surgery or rehabilitation to help doctors determine how to balance urine output and fluid replacement to ensure that patients can achieve normal urine output during surgery or rehabilitation, especially the oral intake required by patients at different stages of rehabilitation, which cannot be grasped by the patient's caregiver.

[0008] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this invention, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that the present invention does not possess the features of these prior art. On the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Summary of the Invention

[0009] In current technologies, indwelling urinary catheters are inserted manually. Spinal surgery patients often cannot control their urination independently and require a caregiver to operate them. For severely injured spinal patients who are bedridden for extended periods, traditional indwelling catheters require manual intervention, as patients lack urinary control. In case of accidents, such as caregivers forgetting, patients may experience bladder overdistension or even catheter-related urinary tract infections. Because traditional indwelling catheters require manual or no urination control, they cannot accurately determine bladder pressure and urine output for critically ill patients requiring urine volume monitoring. Caregivers, due to limited education or cognitive biases, may not accurately determine the timing of catheter clamping and record the urine output, thus delaying patient treatment.

[0010] To accurately balance the relationship between a patient's fluid intake and the catheterization process, existing technologies have developed solutions that combine a diet management device and a catheterization management device to jointly control the relationship between the water content of the patient's ingested food and catheterization parameters. For example, patent document 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 and a first sensing component and a display connected to the weighing component. The first sensing component identifies the type of food ingested by the patient, the weighing component weighs the food, and the display shows the water content of the food. The catheterization management device includes a catheterization management component for catheterizing the patient and detecting the amount of urine and residual urine. This technical solution's diet and catheterization management system accurately measures the water content of the patient's ingested food, and based on this water content, accurately determines the next catheterization time, thus facilitating the patient's recovery. However, this technical solution aims to detect the actual water content ingested by the patient through food and use this as the basis for adjusting catheterization parameters. The amount of water ingested by the patient does not directly participate in the urine drainage process. Therefore, even if the catheterization parameters change due to the patient's water intake, the adjustment logic remains limited to parameters related to catheterization and does not consider adjustments to the patient's active or passive water intake to control parameters related to the catheterization process. This approach is still detrimental to the patient's health. For example, if the patient ingests excessive water through food, the solution might increase the frequency or volume of catheterization, which is detrimental to the patient's ability to regain voluntary urination control.

[0011] This application provides an intelligent remote control system for indwelling urinary catheters after spinal surgery, comprising: a urine control module that switches control states based on detected bladder pressure; and a doctor's terminal that communicates with a hospital management cloud and is capable of adjusting the urine control module to automatically control the patient's urination behavior. This application also relates to an intelligent remote control system for indwelling urinary catheters.

[0012] When the urine volume detected by the urine control module exceeds the preset range on the doctor's end, the hospital management cloud obtains the patient's actual total fluid replacement volume based on the oral intake volume generated by the oral intake detection module and the patient's injection volume. By comparing the patient's actual total fluid replacement volume with the preset total fluid replacement volume, a program is generated for selectively adjusting the patient's injection volume and / or oral intake volume. The adjustment of the injection volume is evaluated and authorized by the doctor 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 based on the data related to the patient's sensory perception of eating fed back by the patient's personal control terminal.

[0013] Unlike existing technologies, the doctor's end in this invention can communicate with a hospital management cloud and adjust the urine control module to automatically control the patient's urination behavior. When the urine volume detected by the urine control module is abnormal compared to the preset reference value on the doctor's end, the hospital management cloud of this invention can generate a program to selectively adjust the patient's injection volume and / or oral intake based on different correlated data according to the detected total fluid replacement volume. Based on the above distinguishing technical features, the problem to be solved by this invention may include: how to adjust active and passive fluid intake according to the real-time changes in the patient's urine output so that the patient's urine output can meet preset indicators. Specifically, the beneficial effects of this technical solution are:

[0014] The urine control module of this application is equipped with a bladder pressure detection component and a urinary catheter opening and closing component. Through dual detection of urine output and the pressure value in the bladder that represents urine output, the module enables automated control of the patient's urination.

[0015] The system in this application is equipped with both automated and manual control, and the control status is switched in real time based on the patient's urination status.

[0016] Compared to existing urine testing systems, the system described in this application uses urine volume as a benchmark to adjust and consider the patient's intake (including oral and injected amounts) and urine production rate. Urinary control, urine volume monitoring, and intake control form an interconnected cycle. This system monitors all factors within this cycle and sets intelligent benchmarks for each factor to control the patient's postoperative renal condition, rather than simply focusing on urination control.

[0017] According to a preferred embodiment, when the bladder pressure collected by the bladder pressure detection component of the urine control module is lower than a preset first threshold for a period of time exceeding a preset range, or when the patient's urine volume collected by the urine volume detection component of the urine control module is lower than a preset threshold, the hospital management cloud obtains the patient's injection volume and oral intake volume respectively, and selectively adjusts the patient's injection volume and / or oral intake volume under the authorization of the doctor based on the patient's physiological data fed back by the physiological detection module.

[0018] The beneficial effects of this technical solution are:

[0019] Unlike existing technologies, this application further categorizes the adjustments to the two main factors in fluid replacement: oral intake and injection volume. It uses the patient's urine storage capacity (or the detrusor muscle's strength) as the benchmark, and considers practical methods for increasing fluid replacement through the control of medical staff, rather than simply increasing fluid replacement when urine output is low.

[0020] According to a preferred embodiment, the system is further provided with an oral intake detection module placed in the same space as the patient so as to collect the oral intake of the food when the patient eats. The hospital management cloud 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.

[0021] According to a preferred embodiment, the total fluid replacement volume includes the injection volume generated based on the injection fluid in the doctor's order stored in the hospital management cloud and the oral intake volume confirmed by the patient through an oral intake detection module or personal control terminal.

[0022] According to a preferred embodiment, when the urine volume detected by the urine control module is lower than the minimum endpoint value preset by the doctor, and the fluid replacement volume obtained by the hospital management cloud, which includes the patient's injection volume and oral intake volume, is also lower than the minimum endpoint value preset by the doctor, the hospital management cloud generates a prompt program to increase the patient's oral intake volume based on the patient's recovery progress feedback from the doctor, or a program to increase the patient's injection volume with the doctor's authorization.

[0023] According to a preferred embodiment, when the doctor's feedback on the patient's recovery process indicates that the patient is in the early recovery stage after surgery and cannot eat, the hospital management cloud generates a program to increase the patient's injection volume with the doctor's authorization based on the patient's recovery process feedback.

[0024] According to a preferred embodiment, the urine control module is configured as follows:

[0025] When bladder pressure is below a preset first threshold or above a second threshold, the urine control module has a program that prioritizes controlling the patient's urination. This program includes an intelligent on / off switch for the urinary catheter opening and closing component of the urine control module, based on bladder pressure data collected by the bladder pressure detection component. The intelligent on / off switch for the urinary catheter opening and closing component can be based on preset standards and generated by the system with corresponding instructions for opening and closing the urinary catheter.

[0026] According to a preferred embodiment, the urine control module is configured as follows:

[0027] When bladder pressure is within a range defined by a first threshold and a second threshold, the procedure for controlling urination is prioritized by the patient manually switching the urethral opening and closing component of the urine control module via a personal control terminal. Unlike existing technologies, the urine control module of this invention can adjust the urination control method, which is the first priority, based on the bladder pressure collected by the bladder pressure detection component of the urine control module when it falls within different preset ranges. Based on these distinguishing technical features, the problem this invention aims to solve may include: how to adjust the procedure for controlling urination based on the real-time bladder pressure collected by the bladder pressure detection component of the urine control module, so as to train the patient's urination reflex ability during postoperative recovery and thereby improve the patient's ability to autonomously control the urination process. Specifically, for example, when a patient's bladder pressure is higher than a set second threshold, in order to prevent urinary retention that may cause urethral infection, especially for patients with excessive detrusor muscle tension or low urination reflex sensitivity, this invention can set the urinary catheter opening and closing component to an automatic opening control mode so that urine in the patient's bladder can be discharged in a timely manner; or when a patient's bladder pressure is lower than a set first threshold, in order to achieve the purpose of postoperative detrusor muscle training, especially for patients with detrusor muscle relaxation or sensitive urination reflex, even if the patient chooses to manually open the urinary catheter opening and closing component, the urinary catheter opening and closing component will remain in the closed state, thereby achieving the switching of the corresponding urinary catheter state according to the actual state of the detected bladder pressure, so as to improve the matching between the urination process and the patient's current urination ability.

[0028] According to a preferred embodiment, the urine control module includes a back plate and a urine volume detection component disposed on the back plate for detecting the amount of urine in a urine bag attached to the back plate, wherein the urine bag is suspended on the back plate by a hook disposed on the back plate.

[0029] The beneficial effects of this technical solution are:

[0030] Existing urine volume detection methods mostly involve placing sensors on urine bags or inserting and removing catheters into integrated urine volume detection containers. Considering that the former increases the weight of the urine bag and poses a risk of catheter dislodgement, and the latter causes the distal end of the catheter to loosen and reduce its seal due to repeated insertion and removal (since it is inserted into the body, catheter replacement is generally not considered until the patient is completely free from passive urination control), this application proposes a device that allows patients to change the position of the urine bag in different states, combining the need for catheter opening and closing control and urine volume detection. When the patient is out of bed or in other situations where carrying the device is inconvenient, considering that this process is usually brief, the patient can remove the detection device and hang the urine bag on their body, avoiding the impact of repeated friction of the catheter in the urethra caused by the device being carried around. When the patient is static (e.g., bedridden), the urine bag can be hung back on the device. The device is simple to operate, inexpensive, and reusable (it does not directly contact the patient's bodily fluids, reducing the difficulty of disinfection). Even during promotion, it can be integrated with the system involved in this application and promoted to wards where it is needed.

[0031] According to a preferred embodiment, the doctor's end plans the conditions for the urine control module to switch the urinary catheter state when it is in an automatic control program based on the patient's circadian rhythm.

[0032] The beneficial effects of this technical solution are:

[0033] A patient's urination behavior and urine volume are often important indicators for assessing renal function risk and postoperative recovery. However, current urine volume assessment techniques rely on two main issues. First, they involve manually checking the residual amount in the urine bag. Because the bags are replaced at irregular intervals and have large measurement errors, medical staff cannot detect some early, transient postoperative sequelae that could be identified through urine volume analysis. These sequelae may only be discovered after they have worsened. Second, with the aging population and the increasing prevalence of diseases in younger people, many historical conditions affecting renal function are frequently found in hospitalized patients. Current urine volume assessment techniques often base their assessments on a baseline population, neglecting the impact of historical conditions. The impact of patients' urine output is significant. Furthermore, due to work constraints, medical staff cannot routinely visit wards to check patients' urine output or monitor their 24-hour diet. Using irregular urine output checks to assess a patient's condition introduces considerable error. For example, a patient who experienced frequent dry mouth the previous day might be fed a large amount of high-water-content food, resulting in significantly more urine than the previous day. Alternatively, patients with a history of nephrotic syndrome may have lower urine output than normal (since patient labels do not specify medical histories, this information often requires doctors to access a database, and frequent urine output checks can easily overlook this factor).

Detailed Implementation

[0041] The following is a detailed explanation with reference to the accompanying drawings.

[0042] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. It should be noted that, unless otherwise explicitly specified and limited, the terms "configured as," "provided with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. "Several" means two or more, unless otherwise explicitly and specifically defined. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0043] Patients with severe spinal injuries and those undergoing spinal surgery often have indwelling urinary catheters to assist with urination. During spinal surgery, if a urinary catheter is inserted preoperatively or intraoperatively for 48 hours, factors such as anesthesia, positioning, psychological state, surgical procedures, and individual differences can cause patients to develop a dependence on the catheter during its placement and be affected by urethral irritation, leading to persistent difficulty urinating after catheter removal and resulting in urinary retention. In particular, after general anesthesia, the bladder nerves recover more slowly, and the detrusor muscle contractility weakens. Even if the urination reflex is affected by the catheter, difficulty urinating can still occur, leading to urinary retention. The reported incidence of postoperative urinary retention ranges from 2.3% to 75.0%. Postoperative urinary retention can lead to bladder weakness, increasing the risk of urinary tract infections and sepsis, causing excessive detrusor muscle expansion and damage, ultimately prolonging hospital stays and increasing medical costs. To prevent urinary retention, clamping training allows the bladder to empty and fill regularly, thus exercising bladder function. This is considered an effective measure to prevent urinary retention after catheter removal.

[0044] Therefore, controlling bladder pressure through urination to train the detrusor muscle's contraction ability is a way to help patients quickly regain their bladder voiding reflex after surgery.

[0045] Example 1

[0046] This embodiment provides a fluid replacement monitoring system. This embodiment provides a fluid balance detection system. This embodiment provides a fluid replacement prompt system based on in vivo and in vitro urine output data.

[0047] Figure 1 The functional structure diagram of this system is shown. In the application, the physiological detection module 600, urine control module 100, personal control terminal 500, oral intake detection module 200, doctor terminal 400, and hospital management cloud 300 can establish communication connections via wireless networks (such as Bluetooth, WIFI, NFC, infrared technology, etc.) for data, signals, and / or control signals.

[0048] This application relates to a urine monitoring module. The urine control module 100 includes a main unit 110, a backplate 1101 connected to the main unit 110, a urine volume detection component 1104 disposed on the backplate 1101 to detect the urine volume in a urine bag 700 attached to the backplate 1101, and a catheter opening / closing component 1105 disposed on the backplate 1101 to enclose a catheter 710. 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 separately disposed, 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 structure of the urine bag 700 is based on the structure of a bladder pressure detection urine bag 700 in the prior art. Figure 2The diagram shows a disposable urine bag 700 used in the inventor's current work environment. The urine bag 700 has an inlet at each end connected to a urine catheter 710 and an outlet for emptying the urine from the bag. The Y-shaped tubing of the urine catheter 710 consists of three parts: a pressure detection branch tube, a drainage branch tube inserted into the bladder, and a main tube connecting the two branch tubes to the inlet of the urine bag 700. A medical Luer taper is installed at the proximal end of the pressure detection branch tube to connect to the pressure sensing connector of the bladder pressure sensor 7202. Figure 2 As shown, the bladder pressure sensor 7202 is located at the proximal end of the pressure detection branch of the urinary catheter 710. A balloon 7201 is installed at the proximal end of the drainage branch inserted into the bladder. Medical personnel inflate the proximal end of the pressure detection branch through a medical Luer connector. The gas flows through the drainage branch inserted into the bladder to the balloon 7201, which is connected to it, causing the balloon 7201 placed in the bladder to be locked in place, preventing the urinary catheter 710 from dislodging from the bladder.

[0049] Specifically, the patient-facing side of the main unit 110 is divided into two parts by the display screen 1102 and the back panel 1101, as follows: Figure 2 As shown. Preferably, the back plate 1101 is integrated with the main unit 110. The back plate 1101 is provided with a hook 1103, a urine catheter opening / closing assembly 1105, and a urine volume detection assembly 1104. The hook 1103 is used to attach the urine bag 700, allowing the urine bag 700 to be suspended from the back plate 1101 by gravity. The urine volume detection assembly 1104 is disposed on the back plate 1101 along a first direction, for example, parallel to the urine bag 700. One end of the urine bag 700 has an opening for connection to the urine catheter 710, and the other end has an opening with a stop valve. Preferably, the urine volume detection assembly 1104 can be an optical liquid level sensor, for example, using an infrared sensor to detect the liquid level. The first direction is the extending direction of the back plate 1101.

[0050] The urinary catheter 710 is fastened to the urinary catheter opening and closing assembly 1105. Specifically, the urinary catheter 710 is configured as a Y-shaped tube, with its two branches connected to the balloon 7201 and the bladder pressure sensor 7202, respectively. When the main tube is closed under the control of the urinary catheter opening and closing assembly 1105, the two branches are connected, and the pressure detected by the pressure sensor is the bladder and urethral pressure. The pressure sensor transmits the detected pressure value to the host 110 and generates corresponding bladder pressure data.

[0051] In use, a tubing 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, biocompatible polymers. After the balloon 7201 is inserted into the bladder, saline or other sterile solution is injected into it through the external tubing to inflate it until a predetermined pressure or volume is reached. The balloon 7201 engages with the inside of the bladder, allowing urine to flow only from the urinary catheter 710.

[0052] A pressure sensor is installed at the other end of the Y-shaped catheter 710. Since the distal end of the catheter 710 is connected to a sealed bag, and the end with the balloon 7201 substantially connects the bladder and the end with the pressure sensor, the pressure sensor can detect changes in pressure within the bladder when the urine volume changes. Preferably, the pressure sensor can be a miniature piezoelectric sensor, a capacitive sensor, or other type of pressure sensor. The pressure sensor detects and converts pressure changes into electrical signals. These signals are then transmitted to an external monitoring device (e.g., a hospital management cloud 300), whereby the patient's intrabladder pressure can be recorded and analyzed. Preferably, the bladder pressure sensor 7202 may include wireless data transmission capabilities to ensure real-time data transmission to the hospital management cloud 300. Furthermore, the pressure sensor may be powered by an integrated battery or wireless power transfer technology to reduce maintenance frequency and improve patient comfort.

[0053] like Figure 4 As shown, in actual use, when the patient is lying in bed, the height of the urine bag 700 must not exceed the height of the patient's perineum to avoid urine reflux and infection. However, due to different postoperative bed height requirements of patients, such as the height of the perineum from the ground for supine and prone positions, the main unit 110 involved in this application is equipped with a height-adjustable support rod. When the urine bag 700 is hung on the back panel 1101, by adjusting the height of the main unit 110, the urine bag 700 can always be kept below the height of the patient's perineum.

[0054] The display screen 1102 can display real-time urine volume, preset urine volume transmitted from the doctor's terminal 400 or the hospital management cloud 300, fluid replacement volume transmitted from the hospital management cloud 300, and an assessment result regarding whether the patient's current oral intake is healthy. To facilitate the patient's caregiver in obtaining prompts about the patient's oral fluid intake through the difference between the real-time urine volume and the preset urine volume, the display screen 1102 is equipped with the aforementioned basic data.

[0055] This application relates, in one aspect, to a physiological monitoring module 600 that is wirelessly connected to a hospital management cloud platform 300. The physiological monitoring module 600 can be any monitoring device currently used by patients in the hospital. For example, the physiological monitoring module 600 can be configured as a patient monitor, wearable medical device, etc.

[0056] Another aspect of this application relates to an oral intake detection module 200, which is placed in the same space as the patient so as to collect the oral intake of the food the patient is eating.

[0057] Preferably, the oral intake detection module 200 can be integrated into a bedside table in the patient's ward. For example... Figure 4 As shown, the bedside table in the ward is equipped with a manually switchable weight acquisition component and a camera 210 for capturing images of the table surface. The patient's caregiver can place the food to be ingested on the table and turn it on. The oral intake detection module 200 transmits the collected food weight and image data to the hospital management cloud 300. The hospital management cloud 300 performs similarity comparisons based on images stored in its database to identify the type of food and, combined with the weight data, generates corresponding liquid oral intake characteristics.

[0058] Preferably, the oral intake detection module 200 can be a medical device that is independently installed in the ward, such as... Figure 3 As shown. The oral intake detection module 200 includes a weighing component, a camera 210 mounted on the weighing component, and an identification component disposed inside the housing 220 of the weighing component. The identification component can be a component that identifies the patient and their guardian through methods such as card swiping or fingerprint recording. The weighing component includes the housing 220, a weight sensor, and a communication component with information transmission function. The communication component 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 to capture an image of the food when it is placed in the gravity sensing area 230. The communication component sends the data collected by the gravity sensor and the camera 210 to the hospital management cloud 300. The hospital management cloud 300 calculates the oral intake corresponding to the food.

[0059] Taking the food conversion formula stored in the hospital cloud as an example (there is a certain error in the measurement of the same food moisture content using different methods):

[0060] 1. Classified by water content: water, tea, beverages, and fresh milk have a water content of 100%; porridge, soup, tofu, fresh vegetables, and fruits have a water content of 90%; yogurt, ice cream, and thick porridge have a water content of 80%; rice, potatoes, fresh fish and shrimp, meat, eggs, dried tofu, and pancakes have a water content of 70%; steamed buns, pancakes, bread, baked flatbread, noodles, various cooked meats, vermicelli, dried bean curd sticks, snacks, and dried goods (cooked) have a water content of 30%.

[0061] Based on this standard, when the food is staple food (rice) and weighs 0.1kg, according to the relevant conversion formula stored in the database of Hospital Management Cloud 300, Hospital Management Cloud 300 knows that the patient's oral intake is 0.07kg.

[0062] 2. According to the corresponding ratio of food to water shown in Table 2, when the food is watermelon, the weight is 0.5kg. Based on the relevant conversion formula stored in the database of Hospital Management Cloud 300, Hospital Management Cloud 300 knows that the patient's oral intake is 0.395kg.

[0063] The doctor's terminal 400 and the patient's personal control terminal 500 in this application can be configured as mobile smart devices, such as mobile phones, controllers, PCs, medical PDAs, etc.

[0064] The urine control module 100 can switch control states based on the detected bladder pressure. The urine control module 100, equipped with a bladder pressure detection component 720, switches between a state where manual control is the first priority and a state where intelligent switch is the first priority based on the collected bladder pressure data.

[0065] 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 a preset first threshold or higher than a second threshold, the urine control module 100 is equipped with a program for controlling the patient's urination with a first priority. This program includes an intelligent switch for 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. The intelligent switch for the urinary catheter opening and closing component 1105 can be based on preset standards, with the system generating corresponding instructions for opening and closing the urinary catheter opening and closing component 1105. Specifically, when the patient's bladder pressure is higher than the second threshold, for patients with excessive detrusor muscle tension or low urination reflex perception, in order to prevent urinary retention problems that may cause urinary tract infection in the patient's bladder, the urinary catheter opening and closing component 1105 will automatically open, 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 muscle or sensitive urination reflex, in order to achieve the purpose of postoperative detrusor muscle training, even if the patient chooses to manually open the urinary catheter opening and closing component 1105, the urinary catheter opening and closing component 1105 will remain in the closed state.

[0066] According to a preferred embodiment, when the doctor's terminal 400 provides a medical order related to the patient's recovery process, indicating a postoperative period of fasting and no food intake, the hospital management cloud 300 generates a program, with authorization from the doctor's terminal 400, to increase the patient's injection volume based on the patient's recovery process reported by the doctor's terminal 400. Preferably, the patient's recovery process reported by the doctor's terminal 400 includes: a patient in the initial postoperative recovery period of fasting and no food intake who is using increased injection volume as a means to increase fluid replacement; a patient in the middle postoperative recovery period of consuming liquid foods who is using increased injection volume as a means to increase fluid replacement; and a patient in the final postoperative recovery period of normal diet who is using increased injection volume as a means to increase fluid replacement.

[0067] According to a preferred embodiment, when the bladder pressure is within a range defined by a first threshold and a second threshold as critical points, the procedure for controlling the patient's urination is prioritized by having the patient manually switch the urinary catheter opening / closing component 1105 of the urine control module 100 on and off via a personal control terminal 500. When the bladder is in a normal state (pressure within a range defined by the first and second thresholds as critical points), the detrusor muscle has been exercised, and due to differences in individual patient perception, the patient will generate a need to urinate based on their own state when the bladder is at different pressure values. This response is beneficial for training the urination reflex during the patient's postoperative recovery process, i.e., the patient consciously chooses to urinate under reasonable bladder conditions. Therefore, in this scenario, the urinary catheter opening / closing component 1105 is opened or closed manually.

[0068] According to a preferred embodiment, the first threshold and the second threshold can be adjusted by the urine control module 100 under instructions sent by the hospital management cloud 300 according to changes in urine volume. Forced urination or forced urination needs to be managed in conjunction with the patient's daily or current urine volume. Based on information about the patient's recovery progress sent by the doctor's terminal 400 (the doctor updates the patient's status through the doctor's terminal 400 through activities such as ward rounds), the hospital management cloud 300 can generate the first threshold and the second threshold by combining 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 early stages of surgery, urination and achieving a reasonable urine output are more important for medical staff to detect potential health problems promptly. Therefore, when the patient's real-time urine output is 0, the first threshold generated by the hospital management cloud platform 300 is the smallest value among multiple first thresholds given by the doctor's terminal 400. When the hospital management cloud platform 300 modifies the patient's recovery process based on information sent from the doctor's terminal 400 to the end of surgery and / or when the patient's real-time urine output reaches 1500 mL (normal daily urine output is approximately 1500-2000 mL), the hospital management cloud platform 300 can increase the value of the first threshold. Preferably, for each additional stage of the patient's recovery process (e.g., from the early stage of surgery to the middle stage; urine output increasing by 500 mL), the first threshold can be increased by a preset gradient value.

[0069] According to a preferred embodiment, the doctor's terminal 400 plans the conditions for the urine control module 100 to switch the state of the urinary catheter 710 when it is in an automatic control program based on the patient's circadian rhythm. Given a determined patient urine output and recovery progress, the patient's disease and historical urination data can be used to assess the conditions for switching the state of the urinary catheter 710 when the patient is awake or in a comatose state. When the patient is in a comatose 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 frequency of urination in the patient's historical urination data stored in the database of the hospital management cloud 300 as the frequency of automatically opening the urinary catheter 710, and automatically opening the urinary catheter 710 when the bladder pressure is higher than a second threshold. When the patient is awake, 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 aforementioned "influence of detected bladder pressure".

[0070] The physician's terminal 400, held by the medical staff responsible for the patient, communicates with the hospital management cloud 300. Based on physiological indicators fed back by the physiological monitoring module 600, the physician's terminal 400 adjusts the urine control module 100, which has the ability to detect urine output and control catheter opening and closing, to automatically control the patient's urination behavior when the bladder pressure is below a first threshold or above a second threshold by opening or closing the catheter 710 when the patient is awake, based on physiological indicators fed back by the physiological monitoring module 600. Preferably, the hospital management cloud 300 can be a HIS system.

[0071] 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 replacement volume includes the injection volume generated based on the injection order issued by the doctor's terminal 400 and stored in the hospital management cloud 300, and the oral intake volume confirmed by the patient through the oral intake detection module 200 or the personal control terminal 500.

[0072] like Figure 5 As shown, when the urine volume detected by the urine control module 100 exceeds the preset range of the doctor's terminal 400, the hospital management cloud 300 generates a program to selectively adjust the patient's injection volume and / or oral intake volume based on the total fluid replacement volume obtained from the patient detection module.

[0073] like Figure 5 As shown, 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 for a period of time exceeding a preset range, or when the patient's urine volume 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 obtains the patient's injection volume and oral intake volume respectively, and selectively adjusts the patient's injection volume and / or oral intake volume under the authorization of the doctor's end 400 based on the patient's physiological data fed back by the physiological detection module.

[0074] like Figure 5 As shown, when the urine volume detected by the urine control module 100 is lower than the minimum endpoint value preset by the doctor's terminal 400, and the fluid replacement volume including the patient's injection volume and oral intake volume obtained by the hospital management cloud 300 is also lower than the minimum endpoint value preset by the doctor's terminal 400, the hospital management cloud 300 generates a prompt program to increase the patient's oral intake volume or a program to increase the patient's injection volume with the authorization of the doctor's terminal 400 based on the patient's recovery progress reported by the doctor's terminal 400.

[0075] Specifically, when the urine volume U detected by the urine control module 100 is lower than the minimum endpoint value V preset by the doctor's terminal 400... minWhen the fluid replacement volume R including the patient's injection volume and oral intake obtained by the hospital management cloud 300 is also lower than the minimum endpoint value P of the range preset by the doctor's terminal, 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 terminal based on the patient's recovery process feedback by the doctor's terminal 400, which can be expressed as:

[0076] When U < V min And when R < P, execute f(T)(1).

[0077] In the formula, f(T) is a program generated according to the patient's recovery process T.

[0078] In this program, the hospital management cloud 300 can preset the patient's recovery process, for example, divided into three stages. The doctor's terminal can feedback to the hospital management cloud when there is a change in the patient's recovery process.

[0079] According to a preferred implementation manner, when the medical advice related to the patient's recovery process feedback by the doctor's terminal is in the recovery state of the initial stage of the operation where the patient cannot eat after surgery, the hospital management cloud generates a program to increase the patient's injection volume with the authorization of the doctor's terminal based on the patient's recovery process feedback by the doctor's terminal, which can be expressed as: g(M)(2). 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.

[0083] The configuration of the urine control module 100 can be expressed by the following formula:

[0084]

[0085] In the formula, B is the bladder pressure, and θ1 and θ2 are the preset first and second thresholds.

[0086] 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:

[0087]

[0088] Based on the detection of the above real-time bladder pressure to adjust the urination mechanism, the purpose of enhancing the patient's autonomous control ability can be achieved.

[0089] 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 in charge of the patient, sends the patient's recovery 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 preset range of the doctor's terminal 400 and the doctor's terminal 400 confirms that the patient is without complications after receiving data from the physiological detection module (the confirmation information of the doctor's terminal 400 confirming that there are no complications 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 increased urine volume for patients in the early stage of surgery by increasing the injection volume (so as to increase the total fluid replacement volume). When the urine volume collected by the urine volume detection component 1104 of the urine control module 100 exceeds the preset range of the doctor's terminal 400, and the doctor's terminal 400 confirms that the patient is in good condition after receiving data from the physiological detection module, the hospital management cloud 300 promotes increased urine volume for patients in the final stage of surgery by increasing oral intake (thus increasing the total fluid replacement volume). When the urine volume collected by the urine volume detection component 1104 of the urine control module 100 exceeds the preset range of the doctor's terminal 400, and the doctor's terminal 400 confirms that the patient is in good condition after receiving data from the physiological detection module, the hospital management cloud 300 promotes increased urine volume for patients in the middle stage of surgery by increasing oral intake / injection volume (thus increasing the total fluid replacement volume).

[0090] Adjustments to the injection volume are assessed and authorized by the doctor (400) based on data related to the patient's urine output fed back from the hospital management cloud (300); adjustments to the oral intake volume are assessed and authorized by the doctor (400) based on data related to the patient's sensory experience of eating fed back from the patient's personal control terminal (500). Specifically, for patients in the mid-stage of surgery who can eat normally but may experience postoperative reactions, the hospital management cloud (300) can selectively adjust the oral intake / injection volume based on sensory feedback information on food provided by the patient (500) to the hospital management cloud (300) (or by medical staff during ward rounds via the doctor (400)). This feedback includes information such as the patient selecting "allowing to increase food intake" on their personal control terminal (500) and the patient selecting "allowing to increase food intake" on their personal control terminal (500). For example, when a patient sends a feedback message to the hospital management cloud 300 via their personal control terminal 500 stating that they cannot increase their food intake, the hospital management cloud 300 can increase the injection volume (e.g., by adding two bottles of normal saline) with authorization from the doctor's terminal 400. Conversely, when a patient sends a feedback message to the hospital management cloud 300 stating that they can increase their food intake, the hospital management cloud 300 can increase both oral intake and injection volume with authorization from the doctor's terminal 400 (e.g., based on oral intake data transmitted by the oral intake detection module 200, the hospital management cloud 300 calculates the difference in the patient's daily oral intake when it is less than 1000 mL, and prompts the patient to drink water equal to the calculated difference). Preferably, the balance between total fluid replacement and urine output is pre-set by medical staff in the hospital management cloud 300 via the doctor's terminal 400; for example, a total fluid replacement volume greater than 0.8 times the urine output indicates that the patient's total fluid replacement volume is normal.

[0093] Specifically, the total amount of raw materials for processed foods in Table 2 refers to the weight of the main raw materials used to prepare the food, such as rice, noodles, eggs, and meat (oil, water, or seasonings used during processing are not included in the weight calculation). For example: when processing rice, 50g of raw rice contains 80g of water after cooking. When processing rice porridge, 50g of raw rice contains 400g of water after cooking. 250g of soaked soybeans contains 230g of water after being made into soy milk. 100g of raw noodles contains 200g of water after being cooked into a small amount of noodles with broth.
