-: 31.1, carry out with the reverse osmosis water after heating the peritoneal dialysis solution that proportioning becomes 37 DEG C, this peritoneal dialysis solution is detected and feedback regulation by conductivity detection module, makes it reach the dialysis solution of preset concentration 135ms/cm-145ms/cm.Before dialysis starts, machine by peritoneal dialysis liquid good for proportioning after antibacterial, endotoxin filter, be stored in the peritoneal dialysis solution storage container of 10L taper, have dialysis solution weight sensor, dialysate temperature sensor, dialysis solution heater and conductivity of dialysate monitoring sensor in peritoneal dialysis solution storage container, the amount that peritoneal dialysis liquid stores is less than or equal to 8L.To be sent in human abdominal cavity according to the flow velocity of 50-200ml/min of setting by dialysis solution front pump and go, when (account form of this pre-filled 2L peritoneal dialysis liquid is learnt by the dialysate meter weight sensor sense in 10L taper peritoneal dialysis solution storage container) after the peritoneal dialysis liquid of 2L enters into abdominal cavity, dialysis solution rear pump starts to rotate with the consistent flow velocity of dialysis solution front pump, this ensures that theres the peritoneal dialysis liquid that intraperitoneal takes 2L in and is in metastable state.Dialysis solution and body metabolism waste exchange must be more, and dialysis-effect is more abundant, and abdominal cavity can not take too many liquid in, designs like this, although intraperitoneal has just taken the peritoneal dialysis liquid of 2L in, in fact abdominal cavity has carried out dialysing with 8L peritoneal dialysis liquid exchanging.Fresh peritoneal dialysis liquid enters in abdominal cavity, utilizes the peritoneum of human body self to dialyse as dialyzer.Carried out the exchange of solute and moisture by the plasma fraction in the blood capillary of the peritoneal dialysis liquid and peritoneum opposite side that pour into abdominal cavity, the metabolite of retention in purged body and too much moisture, supplement the necessary material of body by dialysis solution simultaneously.By constantly upgrading peritoneal dialysis liquid, reaching kidney and substituting or the object of Supporting Therapy.When peritoneal dialysis treatment, dialysis solution is delivered to two-chamber dual-polyester cover X-shaped peritoneal dialysis catheters by dialysis solution front pump and fills with into abdominal cavity.The side of intraperitoneal peritoneum is the blood containing refuse and excessive moisture in peritoneum blood capillary, and opposite side is peritoneal dialysis solution, and the refuse in blood and unnecessary moisture enter in peritoneal dialysis liquid through peritoneum.Peritoneal dialysis solution enters abdominal cavity through two-chamber dual-polyester cover X-shaped peritoneal dialysis catheters Single port, flow out through this pipe other end after intraperitoneal is dialysed, then by dialysis solution rear pump, the peritoneal dialysis solution containing refuse and excessive moisture is extracted from abdominal cavity, the peritoneal dialysis liquid that dialysis solution front pump is drawn is got back in peritoneal dialysis solution storage container after blood leakage monitor, bubble detector, be transported to abdominal cavity by dialysis solution front pump again, so constantly circulate.In figure, the first negative pressure pump and the second negative pressure pump provide power for dialysis solution flows.
In the process of dialysis, the temperature of dialysate temperature Sensor monitoring peritoneal dialysis liquid, heats when temperature is less than 35 degree, and temperature is greater than 37 degree and stops heating, ensures that peritoneal dialysis liquid is in 37 degree.
Dialysis solution front pump and two-chamber dual-polyester overlap between X-shaped peritoneal dialysis catheters a branch, this branch is connected to the pressure of the first pressure transducer being monitored Pipeline transport peritoneal dialysis liquid, when conveying is obstructed, pressure can raise, and machine monitoring will send alarm sound to this situation and stop the rotation of two pumps; Also a branch is had between two-chamber dual-polyester cover X-shaped peritoneal dialysis catheters and dialysis solution rear pump, this branch is connected on the second pressure transducer and monitors the pressure that pipeline extracts peritoneal dialysis liquid out, when extraction is obstructed, pressure can reduce, and machine monitoring will send alarm sound to this situation and stop the rotation of two pumps.Above Liang Ge branch pressure monitoring alarm threshold value can manual adjustments, and pressure can affect to abdominal cavity, and manually can set this value when patient feels under the weather is alarm threshold value.
A dialysis process for automatic carbon hydrochlorate peritoneal dialysis unit, is characterized in that: the method includes the steps of:
First step heating reverse osmosis water: water is heated to 35 DEG C-40 DEG C by the reverse osmosis water water heating rod 92 in water tank 110;
