Description

Technical Field

[0001] This invention belongs to the technical field of medical dialysis auxiliary equipment, specifically an adjustable multifunctional peritoneal dialysis stent and its linkage control method. Background Technology

[0002] With the incidence of chronic kidney disease rising year by year and the number of patients with end-stage renal disease continuing to increase, peritoneal dialysis, as the preferred home-based renal replacement therapy, is widely used in clinical treatment due to its advantages of being minimally invasive, convenient, operable at home, and having minimal impact on hemodynamics. The therapeutic effect of peritoneal dialysis highly depends on standardized operating procedures. Among these, constant temperature preheating of the dialysate, accurate monitoring of fluid intake and output, stable equipment positioning, sterile consumable storage, and appropriate operating angles are the core keys to ensuring dialysis safety, avoiding complications, and monitoring the patient's condition. Currently, most mainstream peritoneal dialysis support stents on the market are traditional, simple mechanical structures with limited functions, only providing basic fluid bag suspension. These are insufficient to meet the needs of modern, intelligent, and age-appropriate dialysis treatment, and the overall level of intelligence, integration, and safety in the industry is generally low.

[0003] Existing peritoneal dialysis stents suffer from several core defects, severely limiting dialysis treatment efficacy and patient autonomy: First, traditional stents lack intelligent movement, alignment, and anti-collision functions, requiring manual handling for equipment transport and bedside alignment. This is cumbersome, results in poor alignment accuracy, and is highly susceptible to equipment collisions and displacement, affecting the stability of the dialysis tubing. Second, they lack a precise constant-temperature heating system. Conventional heating equipment uses only a single heating mode without dual hardware and software protection, leading to large temperature fluctuations, the risk of overheating and dry burning, and an inability to stably maintain the optimal medical dialysis temperature of 40°C. Low-temperature medication solutions are easily contaminated. The problems include: firstly, the use of an adjustable multifunctional peritoneal dialysis stent that can cause peritoneal irritation and abdominal pain in patients; secondly, the use of a rudimentary weighing method, which is mostly single-point weighing without anti-shake error tolerance or automatic calculation functions, relying on manual reading and calculation of intake and output, resulting in large measurement errors, easy data omissions, and inability to accurately monitor the patient's ultrafiltration dehydration; and thirdly, the fixed and non-adjustable control panel that cannot adapt to the operating perspective of patients of different heights and postures, making it difficult for elderly and mobility-impaired patients to operate independently. Therefore, this invention proposes an adjustable multifunctional peritoneal dialysis stent and its linkage control method to solve the above problems. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides an adjustable multifunctional peritoneal dialysis stent and its linkage control method, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable multifunctional peritoneal dialysis stent, comprising a moving mechanism, a supporting mechanism on the top of the moving mechanism, a heat preservation mechanism on the top of the supporting mechanism, and a control panel on the side of the supporting mechanism; The moving mechanism includes a support platform, an industrial camera is detachably connected to the end of the support platform, and several anti-collision laser displacement gauges are fixed to the side wall of the support platform.

[0008] Preferably, the support body is slidably connected to the waste cabinet inside it, and at least two waste cabinet moving screws are hinged inside the support body. Each waste cabinet moving screw is engaged with a waste cabinet moving block, and each waste cabinet moving block is fixedly connected to the waste cabinet. At least two waste cabinet motors are also fixed to the side wall of the main body of the bracket. The output shaft of each waste cabinet motor is fixedly connected to the waste cabinet moving screw inside it. A rotation counter is fixed to the bottom of the output shaft of each waste cabinet motor. The peritoneal dialysis bag and the waste bag are fixedly connected by a connecting tube.

[0009] Preferably, the bracket body has a plurality of positioning holes inside, each positioning hole is slidably connected to a positioning shaft, and the plurality of positioning shafts are fixedly connected to the support plate at its top. The other end of the adapter push rod is fixedly connected to the support body at its bottom.

[0010] Preferably, the top pressure sensor has several connecting rods fixed to its top, and the connecting rods are fixedly connected to the main heating box. Both the main heating box and the auxiliary heating shell have heating chambers inside, and the heating chambers are in close contact with the peritoneal dialysis fluid bag inside them. The main heating box and the auxiliary heating shell are detachably connected to the PTC self-regulating heating element inside them, and each PTC self-regulating heating element is detachably connected to a cover plate on the outside. A temperature sensor is fixed inside each of the heating chambers.

[0011] Preferably, the bracket body has a positioning groove inside, and a plurality of positioning strips are slidably connected inside the positioning groove, and an adapter block is fixed inside the plurality of positioning strips; The bracket body is also fixed inside a positioning rail, and a positioning head is slidably connected to the top of the positioning rail. Several springs are fixed to the top of the positioning head, and the top of each spring is fixedly connected to the top wall of the cavity of the adapter block. The positioning head is slidably connected to the cavity of the adapter block. Several positioning rods are fixed inside the cavity of the adapter block, and the positioning rods are slidably connected to the positioning head.

[0012] Preferably, a hinged spherical shell is fixed to the outside of the adapter block, a hinged ball is hinged inside the hinged spherical shell, a flange is fixed to the outside of the hinged ball, a positioning plate is detachably connected to the outside of the flange, and the positioning plate is fixedly connected to the control panel outside it.

[0013] Preferably, a connecting plate is fixed to the side of the hinged spherical shell, a locking screw is engaged with the connecting plate, a connector is fixed to the inner side of the locking screw, a positioning tube is hinged to the outside of the connector, and a brake block is fixed to the inner side of the positioning tube.

[0014] This invention also provides a linkage control method for an adjustable multifunctional peritoneal dialysis stent, which, based on the aforementioned adjustable multifunctional peritoneal dialysis stent, includes the following steps: Step 1: After the equipment is powered on, it automatically completes a self-test, including sensor zeroing, weighing and tare, temperature calibration, motor reset, and zeroing of the rotation counter. The peritoneal dialysis bag is placed inside the heating chamber, and the main heating box and auxiliary heating shell are locked by the positioning screw. A PTC self-limiting temperature heater is installed inside the main heating box and auxiliary heating shell. The waste liquid bag is placed inside the waste tank. The waste tank is controlled by the control panel, which drives the waste tank moving screw to rotate, causing the waste tank moving block to move and close the waste tank. The rotation counter monitors the number of rotations of the waste tank moving screw and transmits the data to the control panel. The control panel determines the moving distance of the waste tank moving block based on the number of rotations of the waste tank moving screw, and determines the moving distance of the waste tank. When the waste tank moves to the preset position, the control panel drives the waste tank actuator to stop working. Step 2: The industrial camera and anti-collision laser displacement meter are controlled by the control panel to work together to monitor the movement of the entire support in real time. The control panel drives the track motor to work, so that the sprocket rotates and drives the two chain tracks to rotate, driving the entire support to move and can be reversed at the same time. When the industrial camera and anti-collision laser displacement meter monitor the distance data between the whole machine and surrounding obstacles, walls and hospital beds in real time, a dual anti-collision logic of visual recognition and distance prediction is formed: when the distance is less than the preset safety threshold, the control immediately triggers deceleration, stopping and voice alarm to prevent collision and displacement. When the main body of the support moves to the side of the bed and the control panel faces the side of the bed, the control panel controls the track motor to stop working. Step 3: Control the extension of the support push rod through the control panel. The height monitoring camera monitors the positional relationship between the control panel and the bed and transmits the data to the control panel. The laser displacement meter transmits the extension data of the support push rod to the control panel in real time. When the control panel is higher than the bed, the support push rod stops extending through the control panel. Step 4: Fix the connecting tube to the reserved tube outside the patient. The patient pulls the positioning plate according to comfort. At this time, due to the action of the spring and positioning rod, the positioning head is tightly attached to the positioning rail, which also facilitates the movement of the positioning head along the positioning rail, thereby ensuring the stability of the adapter block. Step 5: The patient then rotates the positioning plate according to their own posture, which causes the articulated ball to rotate inside the articulated ball shell. When the control panel is adjusted to the required angle, the locking screw is rotated to move the positioning tube, which causes the brake block to move inward until it is in close contact with the articulated ball, thereby preventing the control panel from rotating. Step Six: The patient controls the PTC self-regulating temperature heater via the control panel to heat the peritoneal dialysis bag. Simultaneously, a temperature sensor on the outside of the PTC heater monitors the temperature of the peritoneal dialysis bag and transmits the data to the control panel in real time. Once the bag reaches the required temperature, dialysis begins. Dialysis fluid is drained from the bag. A top pressure sensor monitors the weight of the bag's top in real time and transmits the data to the control panel, comparing it to the weight without the bag to determine the amount of dialysis fluid inside. The dialysis fluid enters the patient's body through the connecting tube after a set dialysis time. After a set time, the control panel directs waste fluid from the patient's body through the connecting tube into the waste fluid bag. A bottom pressure sensor monitors the weight of the waste fluid in real time and transmits the data to the control panel. When the bottom pressure sensor detects that the waste fluid weight has reached the required value, the control panel alarms, allowing the connecting tube to be removed.

A waste container 5 is slidably connected inside the support body 1. A bottom pressure sensor 505 is detachably connected inside the waste container 5. A waste fluid bag 402 is located on top of the bottom pressure sensor 505. The overall movement status of the support is monitored in real time by the industrial camera 201 and the anti-collision laser displacement meter 202, and the monitoring data is transmitted to the control panel 3. The weight data of the peritoneal dialysis fluid bag 401 is collected in real time by the top pressure sensor 604, and the weight information of the waste fluid bag 402 is dynamically monitored by the bottom pressure sensor 505. The bottom pressure sensor 505 and the top pressure sensor 604 transmit the monitoring data to the control panel 3. In this embodiment, the moving mechanism can move and reverse the entire support structure. The supporting mechanism supports the entire support structure, ensuring its stability. The heat preservation mechanism ensures the peritoneal dialysis bag 401 is kept at 40°C, guaranteeing dialysis effectiveness. The entire support structure can be controlled via the control panel 3. The supporting platform 2 supports the supporting push rod 102. The industrial camera 201 and the anti-collision laser displacement meter 202 form a vision + laser dual-mode collaborative monitoring system, collecting data on the overall displacement, surrounding obstacles, and relative position of the bed without blind spots, thereby determining the position of the support body 1 relative to the bed.

A laser displacement meter 202 measures distance in real-time; it automatically decelerates when the distance is ≤5cm and immediately stops with a voice alarm when the distance is ≤3cm. An industrial camera 201 identifies the edge features of the bed and automatically locks the walking mechanism when the horizontal distance between the panel and the bed is 10±2cm. The support body 1 supports the entire support.

There are several support push rods 102, and the other end of each support push rod 102 is fixedly connected to the support body 1 at its top. A storage cabinet 101 is slidably connected inside the support body 1. The support body 1 is slidably connected to the waste cabinet 5 inside it. At least two waste cabinet moving screws 502 are hinged inside the support body 1. Each waste cabinet moving screw 502 is engaged with a waste cabinet moving block 503. Each waste cabinet moving block 503 is fixedly connected to the waste cabinet 5. At least two waste cabinet motors 501 are also fixedly fixed to the side wall of the support body 1. The output shaft of each waste cabinet motor 501 is fixedly connected to the waste cabinet moving screw 502 on its inner side. A rotation counter 504 is fixedly fixed to the bottom of the output shaft of each waste cabinet motor 501. The peritoneal dialysis bag 401 and the waste bag 402 are fixedly connected by a connecting pipe 4. In this embodiment, the chain track 203 facilitates the movement of the entire support frame. The sprocket 204 drives the chain track 203 to rotate. The balance wheel 205 ensures the stability of the chain track 203. A rubber layer is adhered to the outer surface of the chain track 203. The positioning frame 206 is used to position the balance wheel 205. The support rod 208 is used to position the positioning frame 206. The track motor 207 drives the sprocket 204 to rotate. Dual motor independent speed control achieves differential steering, allowing for straight-line movement / in-place reversal without a steering mechanism. The height monitoring camera 209 monitors the relative position image data of the control panel 3 with the patient bed and the human operating area, thereby facilitating the operation of the control panel 3 by staff. The laser displacement meter 104 monitors the extension and retraction length of the support push rod 102. The battery 103 provides the necessary power for the entire support frame. The support push rod 102 is telescopic, thereby driving the support body 1 to rise and fall. The storage cabinet 101 is used to store consumables such as iodine caps, scissors, and tubing. The inner wall is made of antibacterial medical ABS material to meet the requirements of aseptic operation. The waste cabinet moving screw 502 can drive the waste cabinet moving block 503 to move by rotating. The waste cabinet moving screw 502 can drive the waste cabinet moving screw 502 to rotate. The rotation counter 504 can monitor the waste cabinet moving screw 502 and collect the number of rotations of the screw in real time, convert the opening and closing stroke and positioning position of the waste cabinet 5, and realize precise displacement control. The battery 103 is a DC24V isolated power supply battery. The displacement conversion formula is: moving distance = number of rotations × lead. During dialysis, the waste cabinet 5 is half-open and positioned to reserve the tubing channel. When idle, it is completely closed. After the peritoneal dialysis bag 401 is placed, it is automatically positioned with the outlet facing down, without air bubbles and with smooth gravity guidance. In use, the peritoneal dialysis bag 401 is placed inside the heating chamber 706, and the main heating box 7 and the auxiliary heating shell 701 are locked by the positioning screw 703. The PTC self-limiting temperature heater 705 is installed inside the main heating box 7 and the auxiliary heating shell 701. The waste bag 402 is placed inside the waste cabinet 5. The waste cabinet 5 is controlled by the control panel 3, which drives the waste cabinet moving screw 502 to rotate, causing the waste cabinet moving block 503 to move and close the waste cabinet 5. The number of rotations of the waste cabinet moving screw 502 is monitored by the rotation counter 504 and the data is transmitted to the control panel 3. The control panel 3 determines the moving distance of the waste cabinet moving block 503 based on the number of rotations of the waste cabinet moving screw 502, and thus determines the moving distance of the waste cabinet 5. When the waste cabinet 5 moves to the preset position, the control panel 3 drives the waste cabinet 5 to stop working. The control panel 3 controls the industrial camera 201 and the anti-collision laser displacement meter 202 to work together to monitor the movement status of the entire support in real time. The control panel 3 drives the track motor 207 to work, so that the sprocket 204 rotates and drives the two chain tracks 203 to rotate, driving the entire support to move at a differential speed and can be reversed. When the industrial camera 201 and the anti-collision laser displacement meter 202 detect that the support body 1 has moved to the side of the bed and the control panel 3 is facing the side of the bed, the control panel 3 controls the track motor 207 to stop working. The control panel 3 controls the extension of the support push rod 102. The height monitoring camera 209 monitors the positional relationship data between the control panel 3 and the bed and transmits the data to the control panel 3. The laser displacement meter 104 transmits the extension data of the support push rod 102 to the control panel 3 in real time.

The top of the top pressure sensor 604 has a plurality of connecting rods 704 fixedly connected to the main heating box 7. Both the main heating box 7 and the secondary heating shell 701 have heating chambers 70 inside. 6. The heating chamber 706 is in close contact with the peritoneal dialysis fluid bag 401 inside it; the main heating box 7 and the auxiliary heating shell 701 are detachably connected to the PTC self-regulating heating element 705 inside them, and each PTC self-regulating heating element 705 is detachably connected to a cover plate 702; a temperature sensor is fixed inside each heating chamber 706; the bracket body 1 is provided with a positioning groove 803 inside, and a plurality of positioning strips 802 are slidably connected inside the positioning groove 803, and an adapter block 8 is fixed inside the plurality of positioning strips 802; The support body 1 is also equipped with a positioning rail 801, and a positioning head 806 is slidably connected to the top of the positioning rail 801. Several springs 804 are fixed to the top of the positioning head 806, and the top of each spring 804 is fixedly connected to the top wall of the cavity of the adapter block 8. The positioning head 806 is slidably connected to the cavity of the adapter block 8. Several positioning rods 805 are fixed inside the cavity of the adapter block 8, and these positioning rods 805 are slidably connected to the positioning head 806. A hinged spherical shell 304 is fixed to the outside of the adapter block 8. The hinged spherical shell 304 has a hinged ball 303 hinged inside, and a flange 302 is fixed to the outside of the hinged ball 303. A positioning plate 301 is detachably connected to the outside of the flange 302. The positioning plate 301 is fixedly connected to the control panel 3 outside the flange 302. A connecting plate 901 is fixed to the side of the hinged spherical shell 304. A locking screw 9 is engaged with the connecting plate 901. A connector 904 is fixed to the inside of the locking screw 9. A positioning tube 902 is hinged to the outside of the connector 904. A brake block 903 is fixed to the inside of the positioning tube 902. In this embodiment, the positioning hole 601 ensures the stability of the positioning shaft 602, which is used to stabilize the support plate 603. The connecting rod 704 supports the main heating box 7, and the heating chamber 706 positions the peritoneal dialysis bag 401. The cover plate 702 facilitates the removal of the PTC self-regulating heating element 705. The positioning groove 803 positions the positioning strip 802, which positions the adapter block 8. The positioning rail 801 positions the positioning head 806. The cooperation between the positioning rail 801 and the positioning head 806 allows the adapter block 8 to move while ensuring the stability of the support plate 603. When the mounting block 8 is not subjected to external force, it remains stationary. The spring 804 is elastic. The spring 804 and the positioning rod 805 cooperate to ensure the stability of the positioning head 806 when it is raised or lowered. The hinge ball shell 304 and the hinge ball 303 cooperate to facilitate the rotation of the positioning plate 301, thereby facilitating the change of the angle of the positioning plate 301. The locking screw 9 can rotate the connecting head 904 inward by rotating, thereby driving the positioning tube 902 to move inward, thereby causing the brake block 903 to move inward and fit tightly against the hinge ball 303, thereby preventing the hinge ball 303 from rotating on its own, thus ensuring the stability of the positioning plate 301. Before starting dialysis, the connecting tube 4 is fixed to the pre-installed tube outside the patient's body. The patient pulls the positioning plate 301 according to their comfort level. At this time, due to the action of the spring 804 and the positioning rod 805, the positioning head 806 is tightly attached to the positioning rail 801, which facilitates the movement of the positioning head 806 along the positioning rail 801, thereby ensuring the stability of the adapter block 8. Furthermore, the patient rotates the positioning plate 301 according to their own posture, thereby driving the hinge ball 303 to rotate inside the hinge ball shell 304. When the control panel 3 is adjusted to the required angle, the locking screw 9 is rotated, causing the positioning tube to... 902 moves, causing the brake block 903 to move inward until it is in close contact with the hinge ball 303, thereby preventing the control panel 3 from rotating; the patient controls the PTC self-regulating heating element 705 through the control panel 3 to heat the peritoneal dialysis bag 401. At the same time, the temperature sensor outside the PTC self-regulating heating element 705 monitors the temperature of the peritoneal dialysis bag 401 and transmits the temperature data of the peritoneal dialysis bag 401 to the control panel 3 in real time. The patient presets a constant temperature parameter of 40℃ through the control panel 3, and the system starts a two-stage temperature control mechanism: the temperature sensor monitors the temperature of the heating chamber 706 in real time, and if it is lower than 3℃, the temperature will be controlled. The PTC heating element 705 is activated at 8℃ for supplemental heating, and heating stops immediately upon reaching 40℃, maintaining a dynamic constant temperature. Simultaneously, the PTC heating element 705 has a built-in 45℃ physical temperature limit, preventing overheating even in the event of a circuit malfunction, thus thoroughly protecting the peritoneal dialysis fluid's activity and the packaging bag's safety. The temperature is displayed in real-time during heating, and a voice prompt announces the completion of temperature control, making it suitable for elderly patients with poor vision. Dialysis begins, and the dialysate inside the peritoneal dialysis bag 401 is discharged. The top pressure sensor 604 monitors the weight at the top in real-time, calculates the fluid volume based on the weight difference, and transmits the data in real-time to the control panel 3, comparing it with the data when the peritoneal dialysis bag 401 is not in use. The weight is compared to determine the amount of dialysis fluid inside the peritoneal dialysis bag 401 in real time. The dialysis fluid inside the peritoneal dialysis bag 401 enters the patient's body along the connecting tube 4. After a fixed dialysis time, the waste fluid in the patient's body is transported to the waste fluid bag 402 through the control panel 3 along the connecting tube 4. At this time, the bottom pressure sensor 505 monitors the weight of the waste fluid in real time and transmits the data to the control panel 3 in real time. When the bottom pressure sensor 505 detects that the weight of the waste fluid has reached the required value, the waste fluid in the patient's body is discharged, and the control panel 3 alarms, making it convenient to remove the connecting tube 4.

[0023] This embodiment of the adjustable multifunctional peritoneal dialysis stent linkage control method, based on the adjustable multifunctional peritoneal dialysis stent as described above, includes the following steps: Step 1: After the equipment is powered on, it automatically completes a self-test, including sensor zeroing, weighing and tare, temperature calibration, motor reset, and zeroing of the rotation counter. The peritoneal dialysis bag 401 is placed inside the heating chamber 706, and the main heating box 7 and the auxiliary heating shell 701 are locked by the positioning screw 703. A PTC self-limiting temperature heater 705 is installed inside the main heating box 7 and the auxiliary heating shell 701. The waste liquid bag 402 is placed inside the waste tank 5. The waste tank 5 is controlled by the control panel 3, which drives the waste tank moving screw 502 to rotate, causing the waste tank moving block 503 to move and close the waste tank 5. The rotation counter 504 monitors the number of rotations of the waste tank moving screw 502 and transmits the data to the control panel 3. The control panel 3 determines the moving distance of the waste tank moving block 503 based on the number of rotations of the waste tank moving screw 502, and thus determines the moving distance of the waste tank 5. When the waste tank 5 moves to the preset position, the control panel 3 drives the waste tank 5 actuator to stop working. Step 2: Control the industrial camera 201 and the anti-collision laser displacement meter 202 through the control panel 3 to work together and monitor the movement status of the entire support in real time. The control panel 3 drives the track motor 207 to work, so that the sprocket 204 rotates and drives the two chain tracks 203 to rotate, driving the entire support to move and can be reversed at the same time. When the industrial camera 201 and the anti-collision laser displacement meter 202 monitor the distance data between the whole machine and surrounding obstacles, walls and hospital beds in real time, a dual anti-collision logic of visual recognition + distance prediction is formed: when the distance is less than the preset safety threshold, the control immediately triggers deceleration, stopping and voice alarm to prevent collision and displacement. When the support body 1 moves to the side of the bed and the control panel 3 faces the side of the bed, the control panel 3 controls the track motor 207 to stop working. Step 3: Control the extension of the support push rod 102 through the control panel 3. The height monitoring camera 209 monitors the positional relationship data between the control panel 3 and the bed and transmits the data to the control panel 3. The laser displacement meter 104 transmits the extension data of the support push rod 102 to the control panel 3 in real time. When the control panel 3 is higher than the bed, the support push rod 102 stops extending through the control panel 3. Step 4: Fix the connecting tube 4 to the reserved tube outside the patient. The patient pulls the positioning plate 301 according to comfort. At this time, due to the action of the spring 804 and the positioning rod 805, the positioning head 806 is tightly attached to the positioning rail 801, which also facilitates the movement of the positioning head 806 along the positioning rail 801, thereby ensuring the stability of the adapter block 8. Step 5: The patient then rotates the positioning plate 301 according to their own posture, thereby causing the articulated ball 303 to rotate inside the articulated ball shell 304. When the control panel 3 is adjusted to the required angle, the locking screw 9 is rotated, causing the positioning tube 902 to move, causing the brake block 903 to move inward until it is in close contact with the articulated ball 303, thereby preventing the control panel 3 from rotating. Step Six: The patient controls the PTC self-regulating temperature heater 705 via control panel 3 to heat the peritoneal dialysis bag 401. Simultaneously, a temperature sensor external to the PTC self-regulating temperature heater 705 monitors the temperature of the peritoneal dialysis bag 401 and transmits the temperature data to control panel 3 in real time. Once the peritoneal dialysis bag 401 reaches the required temperature, dialysis begins. At this time, the dialysate inside the peritoneal dialysis bag 401 is discharged. The top pressure sensor 604 monitors the weight at the top of the bag in real time and transmits the data to control panel 3 in real time, comparing it with the weight of the bag without a pressure sensor. The weight of the peritoneal dialysis bag 401 is compared to the actual weight to determine the amount of dialysis fluid inside the bag in real time. The dialysis fluid inside the bag 401 enters the patient's body through the connecting tube 4. After a fixed dialysis time, the waste fluid in the patient's body is transported to the waste fluid bag 402 through the connecting tube 4 via the control panel 3. At this time, the bottom pressure sensor 505 monitors the weight of the waste fluid in real time and transmits the data to the control panel 3 in real time. When the bottom pressure sensor 505 detects that the weight of the waste fluid has reached the required value, the control panel 3 will sound an alarm, which will facilitate the removal of the connecting tube 4.

The peritoneal dialysis bag (401) is placed inside the heating chamber (706), and the main heating box (7) and the auxiliary heating shell (701) are locked by the positioning screw (703). A PTC self-limiting temperature heater (705) is installed inside the main heating box (7) and the auxiliary heating shell (701). The waste bag (402) is placed inside the waste cabinet (5). The waste cabinet (5) is controlled by the control panel (3) to drive the waste The material cabinet moving screw (502) rotates, causing the waste cabinet moving block (503) to move, thus closing the waste cabinet (5). The number of rotations of the waste cabinet moving screw (502) is monitored by the rotation counter (504), and the data is transmitted to the control panel (3). The control panel (3) determines the moving distance of the waste cabinet moving block (503) based on the number of rotations of the waste cabinet moving screw (502), and determines the moving distance of the waste cabinet (5). When the waste cabinet (5) moves to the preset position, the control panel (3) drives the waste cabinet (5) to stop working. Step 2: Control the industrial camera (201) and the anti-collision laser displacement meter (202) through the control panel (3) to work together and monitor the movement status of the entire support in real time. The control panel (3) drives the track motor (207) to work, so that the sprocket (204) rotates and drives the two chain tracks (203) to rotate. While driving the entire support to move, it can change direction. When the industrial camera (201) and the anti-collision laser displacement meter (202) monitor the distance data between the whole machine and surrounding obstacles, walls and hospital beds in real time, a dual anti-collision logic of visual recognition + distance prediction is formed: when the distance is less than the preset safety threshold, the control immediately triggers deceleration, stopping and voice alarm to prevent collision displacement. When the support body (1) moves to the side of the bed and the control panel (3) faces the side of the bed, the control panel (3) controls the track motor (207) to stop working. Step 3: Control the extension of the support push rod (102) through the control panel (3), the height monitoring camera (209) monitors the positional relationship data between the control panel (3) and the bed, and transmits the data to the control panel (3). The laser displacement meter (104) transmits the extension data of the support push rod (102) to the control panel (3) in real time. When the control panel (3) is higher than the bed, control the support push rod (102) to stop extending through the control panel (3). Step 4: Fix the connecting tube (4) to the reserved tube outside the patient. The patient pulls the positioning plate (301) according to the comfort level. At this time, due to the action of the spring (804) and the positioning rod (805), the positioning head (806) is tightly attached to the positioning rail (801), which facilitates the movement of the positioning head (806) along the positioning rail (801), thereby ensuring the stability of the adapter block (8). Step 5: The patient rotates the positioning plate (301) according to their own posture, thereby causing the articulated ball (303) to rotate inside the articulated ball shell (304).

Step Six: The patient controls the PTC self-regulating heating element (705) via the control panel (3) to heat the peritoneal dialysis bag (401). Simultaneously, a temperature sensor outside the PTC self-regulating heating element (705) monitors the temperature of the peritoneal dialysis bag (401) and transmits the temperature data to the control panel (3) in real time. When the peritoneal dialysis bag (401) reaches the required temperature, dialysis begins. At this time, the dialysate inside the peritoneal dialysis bag (401) is discharged. The top pressure sensor (604) monitors the weight at the top of the bag in real time and transmits the data to the control panel (3) in real time, comparing it with the weight of the bag without a peritoneal dialysis bag. The weight of the peritoneal dialysis bag (401) is compared to the actual weight of the peritoneal dialysis bag (401) to determine the amount of dialysis fluid inside the bag in real time. The dialysis fluid inside the peritoneal dialysis bag (401) enters the patient's body along the connecting tube (4). After a fixed dialysis time, the waste fluid in the patient's body is transported to the waste fluid bag (402) along the connecting tube (4) through the control panel (3). At this time, the bottom pressure sensor (505) monitors the weight of the waste fluid in real time and transmits the data to the control panel (3) in real time.
