Description

Technical Field

[0001] This utility model relates to the field of hemodialysis equipment, and more specifically, to an intelligent management system for disinfectant types. Background Technology

[0002] Hemodialysis is a treatment for end-stage renal failure. After each hemodialysis session or use, some dirt and bacteria remain inside the machine. If this residue is not cleaned promptly, it can clog the internal tubing, affecting subsequent dialysis results. If the machine is not thoroughly disinfected, residual bacteria and their endotoxins can pass through the dialysis membrane into the patient's body, leading to a series of complications. Therefore, daily cleaning and disinfection of the machine are of paramount importance. This ensures the safety of the next patient and adherence to medical standards. However, there is no single, universal disinfectant that can eliminate residual substances in dialysis equipment, such as bacteria, calcium deposits, and lipids / proteins. Therefore, regular disinfection with multiple disinfectants is necessary. Citric acid is typically used for thermochemical disinfection, while sodium hypochlorite is used for chemical disinfection. Sodium hypochlorite has strong disinfection and bactericidal effects and is effective at removing lipids and proteins, but it is also highly corrosive, which can affect the lifespan of the equipment, and it lacks calcium removal capabilities. Citric acid disinfection requires a high temperature of at least 85°C for at least 20 minutes to achieve strong disinfection and bactericidal effects, and it also removes inorganic calcium and other precipitates. In existing medical systems, the disinfection process of hemodialysis equipment usually relies on manual operation. This manual operation can easily lead to problems such as connecting the wrong disinfectant suction tube to the dialysis equipment. Our dialysis equipment has two disinfectant suction tubes for citric acid and sodium hypochlorite, and problems such as using the wrong disinfectant or applying the wrong disinfectant type can occur. If the dialysis equipment can intelligently identify the correct disinfectant type, the above problems can be reduced. Furthermore, if a weekly disinfection plan is introduced, the disinfection cycle and type can be determined every week, reducing the problem of medical staff making mistakes and reducing their disinfection workload.

[0003] How to design an intelligent management system for disinfectant types to accurately identify the types of disinfectants based on existing dialysis equipment, and to ensure that the disinfection of dialysis equipment is completed regularly, thereby reducing operational errors and workload of medical staff, is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] This utility model aims to overcome at least one of the defects (deficiencies) of the prior art and provide an intelligent management system for disinfectant types. This system is used to solve the problem of incorrect disinfectant selection due to possible human error during the disinfection process of hemodialysis equipment, which affects the disinfection effect; and the problem of the huge workload caused by relying on manual records for the regular disinfection of hemodialysis equipment.

[0005] The technical solution adopted by this utility model is an intelligent management system for disinfectant types, comprising: a circulation pipeline including an inlet valve, a waste discharge valve, a first circulation pipeline, and a second circulation pipeline; the first circulation pipeline includes a first inlet end, a first return end, a pre-dialysis mixing pipeline, a balancing chamber, a post-dialysis mixing pipeline, a replacement fluid port, and a waste liquid end; liquid flowing into the first inlet end sequentially passes through the inlet valve, the pre-dialysis mixing pipeline, the balancing chamber, and the post-dialysis mixing pipeline before flowing out through the replacement fluid port; liquid flowing into the first return end flows out through the waste liquid end and then through the waste discharge valve; the second circulation pipeline includes a second inlet end, a second return end, a pre-dialysis mixing pipeline, a balancing chamber, a post-dialysis mixing pipeline, an outlet, and a return port; liquid flowing into the second inlet end... The incoming liquid flows sequentially through the inlet valve, pre-dialysis mixing pipeline, balance chamber, and post-dialysis mixing pipeline before being diverted to the replacement fluid port and outlet. The liquid flowing in from the second return end merges with the return port and waste liquid end before flowing out through the waste discharge valve. The disinfectant pipeline includes a detection device connected to the pre-dialysis mixing pipeline, an MCU module connected to the detection device, and a disinfectant device connected to the post-dialysis mixing pipeline. The disinfectant in the disinfectant device flows into the pre-dialysis mixing pipeline along with the circulation pipeline. The detection device sends the conductivity detection value of the disinfectant to the MCU module. The MCU module determines whether the type of disinfectant in the disinfectant pipeline is correct by comparing whether the conductivity detection value is within the conductivity set value range.

[0006] This system facilitates the pre- and post-dialysis loop circulation of the hemodialysis equipment through the circulation tubing. A detection device connected to the pre-dialysis mixing tubing and a disinfectant device connected to the post-dialysis mixing tubing allow the disinfectant to enter the circulation tubing, eliminating the need for additional detection tubing and improving the flexibility of the management system.

The output end of the circulation pump is connected to the input end of the dry powder cartridge and the input end of the mixing chamber. The output end of the dry powder cartridge is connected to the input end of the degassing chamber and is output to the input end of the mixing chamber by the ultrafiltration B pump connected to the degassing chamber.

[0010] It facilitates extracorporeal circulation of blood through the circulation pump in the pre-dialysis mixing line, degasses the circulating fluid before it enters the balance chamber through the degassing chamber, and ensures that extracorporeal circulation is always maintained at a certain pressure through the pre-dialysis pump.

[0011] Furthermore, an ultrafiltration branch is provided between the inlet valve and the pre-mixing pipeline. The input end of the ultrafiltration branch is connected to the output end of the inlet valve, and the output end of the ultrafiltration branch includes a first ultrafiltration output end connected to the input end of the circulation pump, a second ultrafiltration output end connected to the input end of the mixing chamber via ultrafiltration pump A, and a third ultrafiltration output end connected to the input end of the degassing chamber. The output end of the degassing chamber is connected to the input end of the mixing chamber via ultrafiltration pump B. This facilitates the filtration of the circulating fluid entering the extracorporeal circulation via the ultrafiltration branch, further filtration of the circulating fluid entering the mixing chamber via ultrafiltration pump A, and further filtration of the solution discharged from pump B after degassing via ultrafiltration pump B. Furthermore, the post-dialysis mixing pipeline includes a dialysate filter, a post-dialysis degassing chamber, a post-dialysis pump, and an ultrafiltration pump. The input end of the post-dialysis degassing chamber is simultaneously connected to the output end of the dialysate filter, the output end of the waste liquid end, the output end of the return liquid port, and the output end of the balance chamber. The output end of the post-dialysis degassing chamber is connected to the input end of the waste discharge valve. The output end of the post-dialysis degassing chamber is connected to the input end of the post-dialysis pump and the input end of the ultrafiltration pump. The output end of the dialysate filter is also connected to the input end of the replacement fluid port. The output end of the ultrafiltration pump is connected to the input end of the waste discharge valve.

[0012] It facilitates dialysis of the circulating fluid through the dialysate filter and removes harmful substances from the blood, degasses the postdialysis mixing line through the postdialysis degassing chamber, and further filters the circulating fluid after dialysis through the ultrafiltration pump.

[0013] Furthermore, the balancing chamber is connected between the predialysis mixing pipeline and the postdialysis mixing pipeline. The output end of the predialysis pump and the output end of the postdialysis pump are both connected to the input end of the balancing chamber. The output end of the balancing chamber is respectively connected to the input end of the dialysate filter, the input end of the waste discharge valve, and the input end of the postdialysis degassing chamber.

[0014] It is beneficial to achieve pressure balance between the pre-transfer mixing line and the post-transfer mixing line through the balance chamber, so that the discharged liquid in the circulation line can flow back into the circulation line.

[0015] Furthermore, a circulation valve is provided between the waste discharge valve and the water inlet valve, through which the first return liquid end and the second return liquid end flow back to the first inlet liquid end and the second inlet liquid end.

[0016] It is beneficial to connect the first circulation pipeline and the second circulation pipeline through the circulation valve, thereby achieving the circulation effect of the circulation pipeline.

[0017] Furthermore, the MCU module includes a schedule management module, a cleaning parameter management module, and an alarm module. The schedule management module is used to set the cleaning type, cleaning time, and actions after cleaning of the circulation pipeline. The cleaning parameter management module is used to set the pre-rinse time, circulation rinsing time, post-rinse time, circulation temperature, original disinfectant concentration, diluted disinfectant concentration, and diluted disinfectant conductivity value corresponding to the first or second disinfectant. The alarm module is used to issue an alarm when the conductivity detection value exceeds the conductivity setting range of the MCU module.

[0018] It facilitates the regular disinfection of hemodialysis equipment through the schedule management module, thereby reducing the workload of manual disinfection; it enables the setting of different parameters for hemodialysis equipment under different types of disinfectants through the cleaning parameter management module; and it enables rapid prompting for replacement in case of incorrect disinfectant connection through the alarm module.

[0019] Furthermore, the disinfectant pipeline also includes a signal input module, a communication module, a voltage stabilizing module, a data isolation module, a data conversion module, and a temperature measurement module. The output terminals of the signal input module, the voltage stabilizing module, and the temperature measurement module are electrically connected to the input terminal of the MCU module. The data isolation module, the data conversion module, and the communication module are all bidirectionally electrically connected to the MCU module. The signal input module is used to generate a reference signal for conductivity detection and an input signal for the detection head. The voltage stabilizing module is used to provide a stable voltage. The temperature measurement module is used to measure the temperature value of the standard solution. The MCU module is used for data processing. The communication module is used to realize data interaction. The data isolation module is used to realize communication data isolation. The data conversion module is used to convert the output data. The disinfectant pipeline uses a carbon ring and isolation column assembly as the input detection head. A sine wave signal with adjustable amplitude and frequency is input at one end of the carbon ring and isolation column assembly. The signal flows through multiple sets of carbon ring and isolation column assemblies. A wire is connected at the junction of each carbon ring and isolation column assembly as the signal output. The conductivity value is calculated using the resistance value of the liquid flowing inside the carbon ring and isolation column assembly.

[0021] Furthermore, the signal input module includes several operational amplifiers. The sine wave output by the MCU module passes through a follower composed of operational amplifiers and is combined with another signal using an adder to finally output a signal, which is then output to an external conductor. Both signals are input to operational amplifiers for detection, inversion, and amplification after passing through the conductors. After filtering, they are amplified again by operational amplifiers to obtain a DC voltage input to the MCU module for processing. The operational amplifier amplifies the signal in the first stage more times than it amplifies the signal in the second stage.

[0022] It is beneficial to amplify the signal through an operational amplifier, thereby improving the capture of the signal amplitude.

It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0030] Example

[0031] like Figure 1-5 As shown, this embodiment provides an intelligent management system for disinfectant types, comprising: a circulation pipeline including an inlet valve, a waste discharge valve, a first circulation pipeline, and a second circulation pipeline; the first circulation pipeline including a first inlet end, a first return end, a pre-dialysis mixing pipeline, a balancing chamber, a post-dialysis mixing pipeline, a replacement fluid port, and a waste liquid end; liquid flowing into the first inlet end sequentially passes through the inlet valve, the pre-dialysis mixing pipeline, the balancing chamber, and the post-dialysis mixing pipeline before flowing out through the replacement fluid port; liquid flowing into the first return end flows out through the waste liquid end and then through the waste discharge valve; the second circulation pipeline including a second inlet end, a second return end, a pre-dialysis mixing pipeline, a balancing chamber, a post-dialysis mixing pipeline, an outlet, and a return port; liquid flowing into the second inlet end...

The disinfectant pipeline includes a detection device connected to the pre-dialysis mixing pipeline, an MCU module connected to the detection device, and a disinfectant device connected to the post-dialysis mixing pipeline. The disinfectant in the disinfectant device flows into the pre-dialysis mixing pipeline along with the circulation pipeline. The detection device sends the conductivity detection value of the disinfectant to the MCU module. The MCU module determines whether the type of disinfectant in the disinfectant pipeline is correct by comparing whether the conductivity detection value is within the conductivity set value range.

[0032] In this embodiment, the circulation pipeline draws in disinfectant from the disinfectant device and mixes it. The detection device detects the conductivity of the mixture. When the conductivity value is within the set conductivity value in the MCU module, the disinfectant connected to the surface hemodialysis device is correct. When the conductivity value exceeds the set conductivity value, the disinfectant connected to the surface hemodialysis device is incorrect. The MCU module intelligently distinguishes whether the disinfectant in the disinfectant device is connected correctly based on the conductivity value detected by the detection device, which can prevent equipment damage and accidents. In particular, some disinfectants cannot be heated, and heating them may even cause violent reactions.

[0038] A circulation valve is provided between the waste discharge valve and the water inlet valve, and the first return liquid end and the second return liquid end flow back to the first inlet liquid end and the second inlet liquid end through the circulation valve.

[0039] The MCU module includes a schedule management module, a cleaning parameter management module, and an alarm module. The schedule management module is used to set the cleaning type, cleaning time, and actions after cleaning of the circulation pipeline.

[0040] In this embodiment, the interface of the schedule management module includes a toggle button for the weekly plan, buttons for creating or deleting tasks, a task page display button, and for each task, the day of the week, start time, cleaning type, and actions to take after cleaning. In the disinfection schedule management, by setting the day of the week, start time, cleaning type, and actions to take after cleaning, and opening the weekly cleaning plan, the disinfection type and content for the day can be automatically set before disinfection, avoiding staff misselecting the wrong type. Schedule management through the device reduces errors caused by operational mistakes. If today is the set day of the week, the disinfection type and content for that day will be automatically set.
