Description
Technical field
The present invention relates to field of medical, relate in particular to a kind of dialysate temperature monitoring method, device and peritoneal dialysis instrument.
Background technology
Peritoneal dialysis technology is to be similar to the variant that artificial blood purifies.It is the filter membrane of the good peritoneum of blood supply by utilizing patient as health self.Dialysis solution is inputed to patient's abdominal cavity by conduit, according to penetration theory, urine composition is got rid of and is entered abdominal cavity from blood.After a few hours, then this is carried to the dialysis solution of this urine composition and discharge from abdominal cavity, thereby realize the effect of dialysing.
In existing technology, generally can adopt several diverse ways to carry out peritoneal dialysis.For example, for CAPD (CAPD), patient oneself can manually change dialysis solution, for example, can change dialysis solution every day 4 to 5 times; And for automatization's peritoneal dialysis (APD), one is known as the equipment of circulating instrument (Cycler) can realize at night replacing bag filter automatically, thereby patient can not be restricted by day.
In the peritoneal dialysis of this automatization, abdominal cavity is filled dialysis solution by circulating instrument, and fill volume needs to control, and provide maximum loading to patient is for example 3500ml left and right for common adult.Conventionally, can adopt a standard value as loading, can avoid determining by test the complex work that the peculiar loading of each patient brings.
Conventionally, in peritoneal dialysis instrument, input dialysis solution by a conduit that inserts patient abdominal cavity, this dialysis solution is before flowing to patient abdominal cavity, need be heated suitable temperature (for example 37 DEG C of left and right), for example, to avoid inputting the sense of discomfort that improper temperature (supercool or overheated) dialysis solution causes to patient to patient.Therefore the dialysate temperature in bag filter is very important treatment parameter, and the monitoring of this dialysate temperature is even more important.
In the prior art, before dialysis solution is flowed to patient abdominal cavity, generally adopt heated tray to heat it, now can on heated tray, monitor with the temperature to dialysis solution by set temperature sensor.In the prior art, can adopt the scheme that a sensor is set, in this scheme, in therapeutic process, in the time that the absolute value of the difference between the temperature T 1 of its dialysis solution detecting and default human normal body temperature value T is greater than predetermined threshold value (as 2.5 DEG C), can send alarm signal.Because the service time of APD dialysis machine is long, and high to security requirement, once go wrong, can bring very large harm to patient.Therefore this technical scheme of monitoring dialysate temperature by single-sensor of the prior art, cannot directly judge that whether this sensor is normal, can bring potential risks to like this patient's treatment.Once this sensor due to inside or external cause malfunctioning, cannot obtain the accurate temperature of dialysis solution, can bring very large harm to patient.

Non-therapeutic state comparing unit, for in the time that the residing duty of described peritoneal dialysis instrument is non-therapeutic state, judge the first temperature parameter of dialysis solution that described the first temperature sensor obtains and the second temperature parameter of the dialysis solution that the second temperature sensor obtains between the two the absolute value of difference whether be greater than first threshold;
Non-therapeutic state processing unit, is greater than described first threshold if the judged result of described non-therapeutic state comparing unit is described absolute value, the instruction of reporting to the police, otherwise proceed monitoring.
8. the dialysate temperature monitoring device as described in claim 6 or 7, is characterized in that, described therapeutic state monitoring processing unit further comprises:
Therapeutic state the first comparing unit, for judge the first temperature parameter of dialysis solution that described the first temperature sensor obtains and the second temperature parameter of the dialysis solution that the second temperature sensor obtains between the two the absolute value of difference whether be greater than first threshold,
The first processing unit, for being that described absolute value is greater than described first threshold in the judged result of described therapeutic state the first comparing unit, the instruction of reporting to the police;
Therapeutic state the second comparing unit, for being that described absolute value is while being less than or equal to described first threshold in the judged result of described therapeutic state the first comparing unit, whether the absolute value that judges the difference of described the first temperature parameter and a default fiducial temperature is greater than Second Threshold, and judges whether the absolute value of the difference of described the second temperature parameter and described fiducial temperature parameter is greater than described Second Threshold;
The second processing unit, for being greater than described Second Threshold in the judged result of described therapeutic state the second comparing unit for one of them absolute value, report to the police and point out described in be greater than the corresponding temperature sensor of Second Threshold; All be less than described Second Threshold if judged result is two absolute values, proceed monitoring.
9. dialysate temperature monitoring device as claimed in claim 7, is characterized in that the twice that described first threshold is Second Threshold.
10. a peritoneal dialysis instrument, is characterized in that, is provided with two for monitoring the temperature sensor of its dialysate temperature parameter, and at least further includes the dialysate temperature monitoring device as described in claim 5-9 any one.
