Description
Technical field
The present invention relates to automated peritoneal dialysis field, particularly a kind of peritoneal dialysis solution heater.
Background technology
One of the effective ways of nephrotic's renal function replacement therapy during peritoneal dialysis, because the shortage of kidney source causes the patient of renal transplantation gradually few, and the patient of Blood Dialyzing Center at different levels is gradually saturated, peritoneal dialysis just adopt by increasing patient.In peritoneal dialysis automated peritoneal dialysis due to have quality of life, the dialysis-effect that can significantly improve patient good, not easily cause the advantages such as the complication relevant with operation, estimating that For The Next 3-5 Years is interior will welcome explosive growth.
Dialysis solution is injected abdominal cavity by peritoneal dialysis, and in abdominal cavity, dialysis solution and toxins in human body exchange, and then toxin is got rid of external with dialysis solution.Current peritoneal dialysis dialysis solution used is adopted and is ensured that input dialysate temperature is similar to body temperature in two ways, to ensure that patient's in peritoneal dialysis treatment process is comfortable, one inserts in couveuse by dialysis solution before treatment, take out in time arriving suitable problem and carry out peritoneal dialysis, the method dialysate temperature can with the carrying out for the treatment of, and temperature constantly reduces; Another kind adopts to be provided with heater in one end of infusion pump, dialysis solution after heater process is directly pumped into human body, need medical personnel to intervene heating over the course for the treatment of, and be easy to cause temperature too high, all have adverse effect to dialysis solution and therapeutic effect.
Summary of the invention
The object of the present invention is to provide a kind of peritoneal dialysis solution heater that is rapid, temperature precise control of heating.
The technical scheme realizing object of the present invention is: a kind of peritoneal dialysis solution heater, comprises heating film, heated tray, temperature sensor, relay and temperature control panel;
Heated tray is for placing peritoneal dialysis liquid bag, and heating film is arranged on the back side of heated tray, for dialysis solution provides thermal source; Temperature sensor is for measuring the temperature of heated tray and peritoneal dialysis liquid bag, measuring tempeature value is transferred to temperature control panel by temperature sensor, temperature control panel is according to the dialysate temperature control relay preset, and the heating power of relay to heating film controls.
Compared with prior art, remarkable advantage of the present invention is:
(1) the present invention is controlled relay by temperature control panel, realizes controlling the temperature of heating film;
(2) the present invention is connected in series temperature detect switch (TDS) on heating film electric power loop, automatic cut-off power loop after heated tray temperature reaches predetermined threshold, realizes the temperature control defencive function in the too high situation of temperature.
Accompanying drawing explanation
Fig. 1 is the structural representation of peritoneal dialysis solution heater of the present invention.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Composition graphs 1, a kind of peritoneal dialysis solution heater of the present invention, comprises heating film 1, temperature detect switch (TDS) 2, heated tray 3, temperature sensor, relay 10 and temperature control panel 12;
Heated tray 3 for placing peritoneal dialysis liquid bag, and has heat conduction function, and heating film 1 is arranged on the back side of heated tray, for dialysis solution provides thermal source; Temperature sensor is for measuring the temperature of heated tray 3 and peritoneal dialysis liquid bag, measuring tempeature value is transferred to temperature control panel 12 by temperature sensor, temperature control panel 12 is according to the dialysate temperature threshold value control relay 10 preset, and the heating power of relay 10 pairs of heating films 1 controls; Temperature detect switch (TDS) 2 is arranged in the heating film power supply major loop at the heated tray back side, automatic cut-off power after heated tray temperature reaches predetermined threshold value.
Further, heated tray is also provided with metal button 11, peritoneal dialysis liquid bag is placed on metal button 11, is provided with the temperature sensor for measuring peritoneal dialysis liquid bag in metal button 11.
Below in conjunction with specific embodiment, the invention will be further described.
Embodiment
As shown in Figure 1, the present embodiment comprises 6 temperature sensors, wherein the first temperature sensor 4, second temperature sensor 5 is arranged in Metal buttons 11, for carrying out temperature survey to dialysis solution, three-temperature sensor 6, the 4th temperature sensor 7, the 5th temperature sensor 8, the 6th temperature sensor 9 are arranged on heated tray 3 back side, for carrying out temperature survey to heated tray 3; Above-mentioned 6 temperature sensor measurement temperature values by bus transfer to temperature control panel 12.
The dialysate temperature value of the dialysis solution of acquisition, heated tray 3 temperature value and setting compares by temperature control panel 12, exports pwm control signal; Pwm signal control relay 10 action, realizes controlling the output of heating film 1, and then dialysate temperature is stabilized in setting value.After the temperature of dialysis solution or heated tray 3 exceedes certain threshold value, temperature control panel 12 will cut off PWM and export, and stop heating film 1 to heat, and wait for that dialysis solution and heating film 1 temperature drop to below design temperature, pwm signal control relay 10 action, continue heating.
Temperature detect switch (TDS) 2 is independent of outside temperature control panel 12, and when heated tray 3 temperature is higher than temperature detect switch (TDS) 2 design temperature, temperature detect switch (TDS) action, cuts off 220V power supply, guarantee that heated tray does not produce excessive temperature.
