Description

Technical Field

[0001] The invention relates to the technical field of disinfection, and in particular to a safe heating device for thermal disinfection of dialysis water pipelines. Background Art

[0002] Dialysis is a medical treatment that is mainly used to replace kidney function that is damaged by kidney disease. The main function of the kidney is to remove waste and excess water from the blood while maintaining electrolyte balance and acid-base balance. When kidney function is severely damaged, dialysis can help patients remove these harmful substances to maintain life. Since the water pipes used for dialysis must be completely pollution-free, the water pipes need to be disinfected before use. Hot water is often used for disinfection, so a heating device is needed to heat and disinfect the disinfectant water.

[0003] When the heating device of the prior art heats disinfectant water, the water in the water pipe may not be full, which may cause empty burning, thereby affecting the service life of the water pipe and the heater. In addition, the heating device of the prior art often cannot be fully discharged when it is used.

[0004] Based on this, the present invention designs a safe heating device for thermal disinfection of dialysis water pipelines to solve the above problems. Summary of the invention

[0023] The present invention has the following technical effects:

[0024] 1. When it is necessary to disinfect the dialysis water pipe, start the booster pump. The booster pump transports the disinfectant water in the buffer water tank to the disinfectant water pipe through the outlet pipe. When the disinfectant water moves to the inclined area of ​​the disinfectant water pipe, the PCT heating plate is energized through the power ring and the power block. At this time, the disinfectant water pipe is heated by the PCT heating plate, thereby achieving the disinfection of the disinfectant water inside the disinfectant water pipe. In addition, since the disinfectant water pipes wrapped by the PCT heating plate are all inclined areas with the water inlet lower than the water outlet, when the disinfectant water enters the inclined area of ​​the disinfectant water pipe, it will first fill the inclined area of ​​the disinfectant water pipe and then be transmitted forward, eliminating the situation where the water flow does not fill the pipe, and then eliminating the situation where the pipe is burned out, ensuring the full utilization of all PCT heating plates and improving the service life of the equipment. After disinfection, the disinfectant hands re-enter the buffer water tank through the water inlet pipe, and then the cycle is repeated, and the water temperature is always monitored in real time through the temperature transmitter and control components at the inlet and outlet of the disinfectant water pipe. After the water temperature reaches the required temperature and remains for a period of time, water is taken from the water point, and the disinfectant water at the water point is flushed into the dialysis water pipe to disinfect the water pipe, thereby achieving the disinfection of the dialysis water pipe. When the instrument is not in use, the water in the disinfection water pipe needs to be drained. At this time, the drain valve is opened to allow the water in the disinfection water pipe to be discharged through the drain pipe, and since the disinfection water pipe is an inclined pipe, the disinfection water in the disinfection water pipe can be quickly drained. When the PCT heating plate is damaged or the disinfection water pipe leaks and water is urgently needed, the disinfection water outlet valve and the disinfection water inlet valve are closed and the emergency water valve is opened, so that the water outlet pipe is connected to the water inlet pipe through the emergency water pipe. At this time, water can still be taken from the water point, so that water is still available when the disinfection water pipe or the PCT heating plate fails, and since the PCT heating plate is used to heat the disinfection water pipe and then heat the disinfection water, the PCT heating plate has no contact with the disinfection water, thereby ensuring the purity of the disinfection water.

[0025] 2. When the PCT heating plate needs to be replaced, loosen the bolts to separate the upper and lower parts of the protective sleeve. At this time, turn the two sets of locking caps to make the locking caps detach from the support tube. At this time, the support tube is unlocked, and then the two parts of the support tube are separated and the PCT heating plate to be replaced is pulled out and replaced. When the replacement is completed, the support tube is reassembled and the PCT heating plate is driven to rewrap the disinfection water pipe, and the support tube is slid to the left and right ends of the PCT heating plate. At this time, the protective sleeve is assembled and the length fixing block is clamped in the length fixing slot, and then the locking cap is used to cover and lock the end of the support tube that is away from each other. When the locking cap moves until the power-on ring contacts the power-on block The locking of the support tube and the connection of the PCT heating plate are completed at the same time, thereby realizing the easy disassembly and assembly of the PCT heating plate. When it is necessary to heat the disinfection water pipes of different lengths, it is only necessary to replace the PCT heating plate of the required length, slide the support tube to the left and right ends of the PCT heating plate, and connect the length fixing card block to the appropriate length fixing card slot on the protective sleeve, so that it is applicable to all lengths of disinfection water pipes and PCT heating plates without replacing a new heating device, and when the PCT heating plate needs to be removed, the locking cap must be removed as soon as possible, so that the power must be turned off before the disassembly operation can be performed, thereby ensuring the safety of the operator.

[0056] When it is necessary to disinfect the dialysis water pipe, start the booster pump 15. The booster pump 15 transports the disinfectant water in the buffer water tank 11 to the disinfectant water pipe 13 through the outlet pipe 12. When the disinfectant water moves to the inclined area of ​​the disinfectant water pipe 13, the PCT heating plate 641 is energized through the power ring 632 and the power block 642. At this time, the disinfectant water pipe 13 is heated by the PCT heating plate 641, thereby achieving disinfection of the disinfectant water inside the disinfectant water pipe 13. In addition, since the disinfectant water pipe 13 wrapped by the PCT heating plate 641 is an inclined area with a water inlet lower than the water outlet, when the disinfectant water enters the inclined area of ​​the disinfectant water pipe 13, it will first fill the inclined area of ​​the disinfectant water pipe 13 and then be transmitted forward, thereby preventing the situation where the water flow does not fill the pipe, and further preventing the situation where the pipe is burned out, thereby ensuring the full utilization of all PCT heating plates 641 and improving the service life of the equipment. 4 re-enters the buffer water tank 11, and then the cycle is repeated, and the temperature of the water is monitored in real time by the temperature transmitter and control component at the water inlet and outlet of the disinfection water pipe 13.

At this time, water can still be taken from the water point 4, so that water is still available when the disinfection water pipe 13 or the PCT heating plate 641 fails. In addition, since the PCT heating plate 641 is used to heat the disinfection water pipe 13 and then heat the disinfection water, the PCT heating plate 641 has no contact with the disinfection water, thereby ensuring the purity of the disinfection water;

[0057] When the PCT heating plate 641 needs to be replaced, loosen the bolts to separate the upper and lower parts of the protective sleeve 621, and then rotate the two sets of locking caps 631 to make the locking caps 631 detach from the support tube 611. At this time, the support tube 611 is unlocked, and then the two parts of the support tube 611 are separated and the PCT heating plate 641 to be replaced is pulled out and replaced.
