Description

Technical Field

[0001] The utility model relates to medical equipment, in particular to a 150°C high-temperature sterilization device used for reverse osmosis pure water delivery pipelines for dialysis. Background Art

[0002] The temperature range of 150°C high-temperature moist heat sterilization is generally between 121°C and 134°C. This temperature range is suitable for most conventional moist heat sterilization processes and can effectively kill various microorganisms, including bacteria, viruses and spores. For some special microorganisms or to ensure a more thorough sterilization effect, the sterilization temperature is increased to 150°C and maintained for a few seconds or tens of seconds, and the sterilization time is extremely short. The pure water delivery pipeline in the ward passing through the dialysis water treatment equipment is long, with low flow rate and pressure, and it is relatively easy to form biofilm. High-temperature sterilization at 150°C can meet the high frequency of pipeline disinfection, achieve the purpose of preventive disinfection, and completely eliminate the formation of biofilm. However, the structure of the high-temperature delivery pipeline should be as simple as possible, the pipeline length should be minimized, and the structure should be reasonably designed to reduce temperature loss while ensuring the safety of the high-temperature operating system. Utility Model Content

The inlet pipeline composed of the inlet valve, the circulating pump, the heating component, the inlet water temperature sensor and the inlet water pressure sensor is connected to the ward inlet pipeline, the return pipeline composed of the return valve, the return water pressure sensor and the return water temperature sensor is connected to the ward return pipeline, a drain pipeline is provided on the return pipeline and directly connected to a floor drain, and a one-way valve is provided on the circulation pipeline between the inlet pipeline and the return pipeline.

[0005] The discharge pipeline is provided with a discharge valve, a discharge regulating valve and a safety valve. If the pipeline pressure exceeds the set value, the discharge is automatically carried out through the safety valve to regulate the pipeline pressure.

[0006] The heating component is an over-current resistance heating rod or an electromagnetic induction heating rod.

BRIEF DESCRIPTION OF THE DRAWINGS

[0008] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following is a brief introduction to the drawings required for use in the embodiments. It should be understood that the following drawings only show certain embodiments of the present invention and therefore should not be regarded as limiting the scope. For ordinary technicians in this field, other relevant drawings can be obtained based on these drawings without creative work.

[0010] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0011] like Figure 1 As shown, a 150°C high-temperature sterilization device for reverse osmosis pure water delivery pipeline for dialysis is mainly composed of an inlet valve 11, a return valve 1, a drain valve 3, a circulating pump 12, an inlet water temperature sensor TT1, a return water temperature sensor TT2, an inlet water pressure sensor PT1, a return water pressure sensor PT2, a heating component 13, a safety valve 6 and a control system. The inlet pipeline 10 composed of the inlet valve 11, the circulating pump 12, the heating component 13, the inlet water temperature sensor TT1, and the inlet water pressure sensor PT1 is connected to the ward inlet pipeline, and the return pipeline 2 composed of the return valve 1, the return water pressure sensor PT2, and the return water temperature sensor TT2 is connected to the ward return pipeline. A drain pipeline 4 is provided on the return pipeline and directly connected to the floor drain. A one-way valve 9 is provided on the circulation pipeline 8 between the inlet pipeline and the return pipeline.

[0012] The drainage pipeline is equipped with a drain valve 3, a drain regulating valve 5, and a safety valve 6. If the pipeline pressure exceeds the set value, the safety valve automatically releases the liquid to regulate the pipeline pressure. The heating component is a flow-through resistance heating rod or an electromagnetic induction heating rod. All pipeline instruments are made of 304 or 316 stainless steel.

[0013] During high-temperature sterilization, the dialysis water treatment equipment supplies reverse osmosis pure water to the piping system. The return valve closes and the inlet valve opens. When the pressure sensors for the inlet and return water reach 3 bar, the inlet valve closes, the circulation pump starts, and the heating element begins heating. After the return water temperature reaches 150°C and the disinfection time has expired, the heating element stops heating and circulates to cool the water. When the temperature drops below 80°C, the water is discharged. During the circulating heating process, if the pipeline pressure exceeds the set value, it is automatically discharged through the safety valve to regulate the pipeline pressure.

[0014] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
