[0001] This application relates to the technical field of medical devices, and particularly to a detection device for a hemodialysis device and a hemodialysis system. Background Art

[0002] When using a hemodialysis device to perform dialysis treatment on a patient, the device supplies reverse osmosis water and concentrated liquid to a dialysis liquid supply system, which configures the dialysis liquid, and then pushes the dialysis liquid to a dialyzer. In the dialyzer, solute diffusion, osmosis, and ultrafiltration occur between the dialysis liquid and the patient's blood, achieving the replacement of renal function, purification and elimination of toxins in the blood, and elimination of excess water.

[0003] Currently, the number of hemodialysis patients is huge, and the water treatment equipment and hemodialysis equipment are operating under load. Moreover, peracetic acid disinfection is carried out on the water treatment every six months, and hot water citric acid disinfection is carried out on the dialysis machine after each treatment, which may increase the failure rate and cause dialysis water pollution. Currently, engineers perform off-line reagent tests on the hardness and residual chlorine and total chlorine of dialysis water before starting the machine every day, but they cannot monitor dialysis water in real time. For example, it is impossible to detect in time when the ions in the dialysis water exceed the standard or there is disinfectant residue, which greatly increases the dialysis risk for patients.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

[0024] The core of the present application is to provide a detection device for a hemodialysis device and a hemodialysis system, which are used to monitor the parameters of dialysis water in real time and reduce the dialysis risk of patients.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the following will further describe the present application in detail in conjunction with the accompanying drawings and specific implementation manners.

[0026] Figure 1 It is a top view of a detection device for a hemodialysis device provided in an embodiment of the present application. Figure 2 It is a side view of a detection device for a hemodialysis device provided in an embodiment of the present application. As Figure 1 and Figure 2 shown, a detection device for a hemodialysis device includes: a control CPU board 1, a control drive board 2, a protection CPU board 3, a first PH sensor 4, a second PH sensor 5, a first conductivity sensor 6, a second conductivity sensor 7, and a two-way solenoid valve 8; the control CPU board 1 is respectively connected to the control drive board 2, the protection CPU board 3, the first PH sensor 4, and the first conductivity sensor 6, the protection CPU board 3 is respectively connected to the second PH sensor 5 and the second conductivity sensor 7, the two-way solenoid valve 8 is respectively connected to the control drive board 2 and the protection CPU board 3, and the first PH sensor 4, the second PH sensor 5, the first conductivity sensor 6, the second conductivity sensor 7, and the two-way solenoid valve 8 are all arranged on the water supply pipeline 21 of the dialysis machine 20. The control CPU board 1 can send control commands to the control drive board 2 according to the PH data and conductivity data obtained by itself and / or the PH data and conductivity data sent by the protection CPU board 3, so that the control drive board 2 controls the opening and closing of the two-way solenoid valve 8. The control CPU board 1 can also compare the data obtained by itself with the data obtained by the protection CPU board 3 to determine whether the first PH sensor 4, the second PH sensor 5, the first conductivity sensor 6, and the second conductivity sensor 7 are faulty.

[0027] Among them, the acidity and alkalinity (Pondus Hydrogenii)) describes the degree of acidity and alkalinity of an aqueous solution, and the acidity and alkalinity of a solution is commonly represented by PH; the central processing unit (Central Processing Unit, CPU).

[0028] It is considered that if the water supply pressure does not meet the preset requirements, it will also affect the safety of patient dialysis. In this regard, it also includes a first water pressure sensor 9, a second water pressure sensor 10 and a pressure relief valve 11 provided on the water supply pipeline 21 of the dialysis machine 20. The first water pressure sensor 9 is connected to the control CPU board 1, the second water pressure sensor 10 is connected to the protection CPU board 3, and the pressure relief valve 11 is respectively connected to the control drive board 2 and the protection CPU board 3. The control CPU board 1 can compare the water pressure data obtained by itself with the water pressure data obtained by the protection CPU board 3 to determine whether the first water pressure sensor 9 and the second water pressure sensor 10 are faulty. In addition, by setting the first water pressure sensor 9 and the second water pressure sensor 10, the water pressure of the water supply pipeline 21 can be monitored in real time. When the obtained water pressure data is greater than the preset water pressure, the control drive board 2 controls the pressure relief valve 11 to open for pressure reduction.

[0029] When the staff conducts equipment inspections, they cannot directly see whether there is liquid leakage at the bottom and rear of the equipment. If there is a hidden water outlet point, it cannot be discovered and repaired in time. Only when the liquid area on the ground is too large can it be discovered, which greatly increases the dialysis risk of patients. In this regard, this application also includes a load-bearing base 12 for carrying the dialysis machine 20. The load-bearing base 12 is provided with a funnel-shaped groove 13 for collecting the liquid leakage of the dialysis machine 20. The load-bearing base 12 can use tempered resin material, and the specifications of the load-bearing base 12 can be determined according to the size of the dialysis machine 20. Specifically, a sunken funnel-shaped groove 13 is provided in the middle of the load-bearing base 12, and the bottom edge of the dialysis machine 20 is placed on the load-bearing base 12 at the edge of the funnel-shaped groove 13. The funnel-shaped groove 13 is located below the bottom of the dialysis machine 20. When the dialysis machine 20 leaks, the water flows into the funnel-shaped groove 13 and gathers at the lowest point of the funnel-shaped groove 13. The diameter of the funnel-shaped groove 13 gradually decreases from the top to the bottom, which is convenient for gathering the liquid leakage and facilitating the user to discover the liquid leakage of the dialysis machine 20 in time. As Figure 1 shown, the control CPU board 1, the control drive board 2, and the protection CPU board 3 can be arranged on the load-bearing base 12. In addition, it also includes a power supply 19, which is also installed on the load-bearing base 12, and the power supply 19 is used to supply power to each circuit board.

[0030] Based on this, a first water immersion sensor 14 and a second water immersion sensor 15 are provided at the bottom of the funnel-shaped groove 13. The first water immersion sensor 14 is connected to the control CPU board 1, and the second water immersion sensor 15 is connected to the protection CPU board 3. By setting the first water immersion sensor 14 and the second water immersion sensor 15, the automation of liquid leakage detection can be realized, and the timeliness of liquid leakage detection can be further improved. In addition, the control CPU board 1 can compare the electrical signals obtained by itself with the electrical signals sent by the protection CPU board 3 to determine whether the first water immersion sensor 14 and the second water immersion sensor 15 are faulty.

[0031] Both the first water immersion sensor 14 and the second water immersion sensor 15 include a housing, a probe, and a controller. The controller is disposed within the housing. One end of the probe is connected to the controller, and the other end of the probe extends out of the housing. A waterproof and corrosion-resistant sealing layer is wrapped around the surface of the controller. Specifically, the sealing layer can be made of epoxy resin material, and the design of the sealing layer can extend the service life of the water immersion sensor.

[0032] Based on the above embodiments, in the embodiment of the present application, a positioning groove is provided on the load-bearing base 12. The positioning groove is arranged around the edge of the funnel-shaped groove 13 and is adapted to the universal wheels at the bottom of the dialysis machine 20. A gravity sensor is provided in the positioning groove, and the gravity sensor is connected to the control CPU board 1. The number of the positioning grooves matches the number of the universal wheels at the bottom of the dialysis machine 20. By providing the positioning groove, it is convenient for the staff to place the dialysis machine 20 at a suitable position on the load-bearing base 12. Additionally, when the control CPU board 1 receives the feedback signal from the weight sensor, it can be known that the dialysis machine 20 is placed accurately.

[0033] Based on the above embodiments, in the embodiment of the present application, an extension panel 16 is provided at the edge of the load-bearing base 12. The edge of the extension panel 16 is rotatably connected to the edge of the load-bearing base 12. By providing the extension panel 16, when the extension panel 16 is rotated to contact the ground, a ramp is formed, which can facilitate pushing the dialysis machine 20 onto the load-bearing base 12, making it convenient and labor-saving. Moreover, the extension panel 16 also acts as a guardrail for protection. In the embodiment of the present application, the shape of the extension panel 16 is not specifically limited. It can be a rectangular panel, and one side edge of the panel is rotatably connected to the edge of the load-bearing base 12. As Figure 2 shown, the extension panel 16 is a triangular prism-shaped panel. The cross-section of the triangular prism-shaped panel is a right triangle, and the side edge of the triangular prism-shaped panel is rotatably connected to the edge of the load-bearing base 12. The triangular prism-shaped panel has a stronger load-bearing capacity than the rectangular panel.

[0034] Based on the above embodiments, the embodiment of the present application further includes a display 17 and an alarm device 18 respectively connected to the control drive board 2. Specifically, the display 17 can be a touch display screen, and the alarm device 18 can be an audible and visual horn. The touch display screen is convenient for the user to issue commands, and the touch display screen can display the data of each sensor detected by the control CPU board 1 and the protection CPU board 3, facilitating the staff to monitor and record. The audible and visual horn gives an alarm prompt when the data is abnormal, which can facilitate the staff to discover the situation in time.

[0035] A detection device for a hemodialysis device provided by an embodiment of the present application includes: a control CPU board, a control drive board, a protection CPU board, a first pH sensor, a second pH sensor, a first conductivity sensor, a second conductivity sensor, and a two-way solenoid valve; the control CPU board is respectively connected to the control drive board, the protection CPU board, the first pH sensor, and the first conductivity sensor, the protection CPU board is respectively connected to the second pH sensor and the second conductivity sensor, the two-way solenoid valve is respectively connected to the control drive board and the protection CPU board, and the first pH sensor, the second pH sensor, the first conductivity sensor, the second conductivity sensor, and the two-way solenoid valve are all arranged on the water supply pipeline of the dialysis machine. The control CPU board compares the data obtained by the same type of sensor, can judge whether the sensor fails, and effectively avoids the problem that the data detected by the sensor is inaccurate due to its own failure. The control drive board can control the closing of the two-way solenoid valve when the data detected by the sensor is abnormal. Compared with manual inspection, it can monitor the parameters of dialysis water in real time and reduce the dialysis risk of patients. In addition, the first water pressure sensor and the second water pressure sensor can monitor the water supply pressure in real time, and the first water immersion sensor and the second water immersion sensor can monitor whether there is liquid leakage, further reducing the dialysis risk of patients.

[0036] To better understand the present application, the following introduces the usage method of the detection device for the hemodialysis device.

[0037] After the hemodialysis machine 20 is shut down, turn on the detection device of the present application. The parameters of each sensor are transmitted to the touch screen display through the control drive board 2, and the values of each sensor and the valve state (the opening and closing states of the two-way solenoid valve 8 and the pressure relief valve 11) are displayed in real time. Click self-check to enter the self-check program. The control CPU board 1 receives the instruction of the touch screen display, performs self-check on the two-way solenoid valve 8 and the pressure relief valve 11. The control drive board 2 sends a signal to control the two-way solenoid valve 8 and the pressure relief valve 11 to do work. The control CPU board 1 and the protection CPU board 3 obtain the valve state. If the states are consistent, the data of each sensor obtained by the control CPU board 1 and the protection CPU board 3 are respectively compared with the input value. If the requirements are met, the self-check is completed. If the self-check fails, the control CPU board 1 transmits the information to the control drive board 2, and the control drive board 2 sends a signal to the touch screen display and the sound and light horn. The touch screen display shows the alarm information, and the sound and light horn flashes and emits a beeping sound.

[0038] After the self-check of the detection device is completed, the hemodialysis machine 20 is powered on for patient treatment. Under normal circumstances, the control CPU board 1 and the protection CPU board 3 receive the data detected by each sensor, and compare the data detected by the same type of sensor. For example, compare the data detected by the first pH sensor 4 and the data detected by the second pH sensor 5. If the difference is within the normal range, the control drive board 2 is controlled to send the data detected by each sensor to the touch screen display, and the engineer can monitor and record. When a sensor is damaged, the difference between the data respectively transmitted by the same type of sensor to the control CPU board 1 and the protection CPU board 3 is outside the normal range, an alarm signal is output to the control drive board 2, the control drive board 2 sends out a signal to control the double-pass solenoid valve 8 to close, and the touch screen display shows the alarm information, and the sound and light horn flashes and emits a beeping sound. The hemodialysis machine 20 cuts off the water supply alarm and only maintains the blood circuit circulation, so that the engineer can check and repair in time.

[0039] When the difference between the data detected by the first pH sensor 4 and the second pH sensor 5 is within the reasonable range, but the pH exceeds the normal value, it indicates that the ions in the dialysis water exceed the standard. The control drive board 2 sends out a signal to control the double-pass solenoid valve 8 to close, and the touch screen display shows the alarm information and the data detected by the first pH sensor 4 and the second pH sensor 5, and the sound and light horn flashes and emits a beeping sound. The hemodialysis machine cuts off the water supply alarm and only maintains the blood circuit circulation so that the engineer can check and repair in time.

[0040] When the difference between the data detected by the first conductivity sensor 6 and the second conductivity sensor 7 is within the reasonable range, but the data exceeds the normal value, it indicates that there is disinfectant residue. The control drive board 2 sends out a signal to control the double-pass solenoid valve 8 to close, and the touch screen display shows the alarm information and the data detected by the first conductivity sensor 6 and the second conductivity sensor 7, and the sound and light horn flashes and emits a beeping sound. The hemodialysis machine 20 cuts off the water supply alarm and only maintains the blood circuit circulation so that the engineer can check and repair in time.

[0041] When the difference between the data detected by the first water pressure sensor 9 and the second water pressure sensor 10 is within a reasonable range, if the pressure is too low, the control drive board 2 is signaled to control the double-pass solenoid valve 8 to close. The touch screen display shows an alarm message, and the sound and light horn flashes and emits a beeping sound. The water supply of the hemodialysis machine 20 is cut off and an alarm is issued, and only the blood circuit is maintained so that engineers can check and repair it in time. If the pressure is too high, the control drive board 2 is signaled to control the pressure relief valve 11 to work. The touch screen display shows an alarm message, and the sound and light horn flashes and emits a beeping sound. The engineer checks the water treatment equipment and repairs it urgently. The water pressure parameters detected by the first water pressure sensor 9 and the second water pressure sensor 10 are fed back to the control CPU board 1 and the protection CPU board 3 in real time. When the water pressure returns to normal, the control CPU board 1 sends a signal to the control drive board 2, and the control drive board 2 controls the pressure relief valve 11 to stop working, stops the sound and light horn, and transmits the signal of returning to normal to the touch screen display for easy identification by the engineer to ensure patient dialysis.

[0042] When the control CPU board 1 and the protection CPU board 3 receive the signals fed back by the first water immersion sensor 14 and the second water immersion sensor 15, it indicates that liquid leakage has occurred. The control drive board 2 is signaled to control the double-pass solenoid valve 8 to close. The touch screen display shows an alarm message, and the sound and light horn flashes and emits a beeping sound. The water supply of the hemodialysis machine 20 is cut off and an alarm is issued, and only the blood circuit is maintained so that engineers can check and repair it in time.

[0043] This application can detect each sensor to prevent inaccurate monitoring data caused by the sensor itself and resulting in misjudgment. The touch screen display provides good human-computer interaction and can view the data parameters monitored by each sensor in real time. The funnel-shaped groove design allows the leaked liquid to gather at the first water immersion sensor and the second sensor, improving the timeliness of liquid leakage monitoring.

[0044] Finally, this application provides a hemodialysis system, which includes a dialysis machine and the detection device of the above-mentioned hemodialysis equipment. Since the components of the detection device have been described in detail above, they will not be elaborated in this embodiment.
