Problems solved by technology

[0005] However, the dissipation coefficient of temperature is greatly related to the environment. It is difficult to control different climatic conditions, indoor temperature, the temperature of water pipes, and the temperature of added liquid. Therefore, the fixed dissipation coefficient K must not meet different requiremen

Embodiment Construction

[0031] When performing dialysis on a patient, the temperature of the final dialysate needs to be consistent with the temperature of the human body. Generally, the temperature of the final dialysate is set at 37°C. However, referring to figure 1 As shown, the initial liquid in the water tank is heated, and the initial liquid is added with A and B liquids during the process of flowing along the water pipe to prepare the dialysate, and finally flows into the dialyzer. During the whole process, the flow of liquid along the water pipe and the process of adding other solutions will cause temperature dissipation, and the coefficient of dissipation in the entire pipeline can be set as the K value.

[0032] Because of this, the temperature of the dialysate in the final dialyzer will be unstable, affecting the treatment of patients. If the dissipation coefficient K is a fixed value, the temperature of the final dialysate will be unstable due to changes in the temperature and environmen...

Abstract

The invention discloses a flowing-liquid temperature control method capable of automatically correcting the dissipation factor. According to the flowing-liquid temperature control method, the temperature and the tolerant dissipation factor of target liquid are set, so that the temperature value which the temperature of initial liquid needs to reach through heating is worked out; next, according to the actual temperature of the final target liquid, the correction factor of the dissipation factor is worked out; a new temperature value which the temperature of the initial liquid needs to reach through heating is worked out according to the correction factor, heating is conducted again, and then the target liquid meeting the demand for the temperature can be obtained finally. By the adoption of the flowing-liquid temperature control method, the dissipation factor can be automatically corrected; the flowing-liquid temperature control method can be adapted to the influence of different environment changes on the temperature; the temperature of dialyzate is kept stable all the time, and therefore the treatment effect on a patient is further improved.

Description

technical field [0001] The invention relates to the medical field, in particular to a method for controlling the temperature of flowing liquid that can automatically correct the dissipation coefficient. Background technique [0002] The hemodialysis machine is divided into two parts: the blood monitoring alarm system and the dialysate supply system. Blood monitoring alarm system includes blood pump, heparin pump, arteriovenous pressure monitoring and air monitoring, etc.; dialysate supply system includes temperature control system, liquid distribution system, degassing system, conductivity monitoring system, ultrafiltration monitoring and blood leakage monitoring, etc. Partial composition. Its working principle is: the dialysis concentrate and dialysis water are prepared through the dialysis fluid supply system to prepare a qualified dialysis fluid, and through the hemodialyzer, it will perform solute dispersion, osmosis and ultrafiltration with the patient's blood drawn by...
