The application provides a medical waste high-temperature steam permeation control treatment method, relates to the field of harmless treatment of medical waste, and comprises the following steps: loading medical waste in a treatment cabin and performing vacuumization on the treatment cabin, so that the pressure in the treatment cabin is reduced to a first target negative pressure value; saturated steam is injected into the treatment cabin, and a multi-stage gradient pressure increasing program is performed, so that the working pressure of the treatment cabin is maintained in a slightly positive pressure state in which a slightly positive pressure offset of the target sterilization pressure is increased; the target sterilization temperature in the slightly positive pressure state is maintained to perform basic heat penetration, and the treatment cabin is subjected to periodic pressure pulse cycle treatment; the target sterilization temperature in the slightly positive pressure state is maintained to perform final sterilization, the treatment cabin is subjected to vacuum drying and air injection into the treatment cabin for cooling, and the treatment cabin is opened to unload the treatment product.

The utility model belongs to the technical field of medical apparatus and instruments, concretely relates to a Tibetan medicine negative pressure copper cupping device, including the jar body, the upper end of jar body is connected with the bottom fixed connection of air inlet pipe, the utility model discloses a air inlet pipe, sealing disc, connecting cylinder, exhaust pipe and pressure measuring cylinder are arranged at the upper end of jar body, when using the device to carry out cupping therapy, can be inserted with the connecting cylinder of connecting pipe, then utilize vacuum pump to draw out the air in jar body to make the negative pressure in jar body, and can utilize the pressure gauge to measure the pressure in jar body to the medical staff accurate control treatment pressure improves the treatment effect, when taking off jar body from the skin of patient, the user can pull up connecting cylinder to make exhaust pipe, fixed disc and sealing disc move up, when sealing disc separates from air inlet pipe, the outside air enters jar body through air inlet pipe to make jar body pressure restore normal, thereby making the process of taking jar not causing damage to the skin of patient also can not aggravate the uncomfortable feeling of patient.

The application discloses a method for geopolymer solidification-thermal consolidation coupling intelligent regulation and control treatment of soft soil foundation, and relates to the field of soft soil foundation treatment. The method comprises the following steps: arranging a vertical drainage path in a target soil body of a soft soil foundation to be treated and laying a sealing film on the ground surface; preparing a precursor and an alkali activator to be incorporated into the target soil body to obtain a mixed solidified soil body; obtaining an average consolidation degree of the last time, determining a target temperature of the current time, and applying a controlled thermal field to make pore water be discharged through the drainage path while a continuous negative pressure field is applied to the mixed solidified soil body; calculating a current average consolidation degree, judging whether an end condition is met, repeating the above steps if the end condition is not met, and gradually reducing the temperature to a preset termination temperature at a preset step length if the end condition is met, then the negative pressure field and the thermal field are removed, and a consolidated soft soil foundation to be treated is obtained. The application solves the problem that the thermal field parameters depend on experience setting and cannot be dynamically adjusted, improves the soft soil foundation treatment efficiency, reduces energy consumption, and reduces carbon emissions.
