Description
Technical field
The present invention relates to field of medical device, particularly relate to a kind of dialysate temperature monitoring method, device and peritoneal dialysis instrument.
Background technology
Peritoneal dialysis technology is the variant being similar to artificial blood purification. It is the filtering membrane of the peritonaeum by utilizing the blood supply of patient good as health self. Dialyzate is inputed to the abdominal cavity of patient by conduit, and according to penetration theory, urinary fractions by getting rid of from blood and enters abdominal cavity. After a few hours, then this dialyzate carrying this urinary fractions is discharged from abdominal cavity, thus realize the effect of dialysis.
In existing technology, several different method generally can be adopted to carry out peritoneal dialysis. Such as, for persistence Non-staying in bed peritoneal dialysis (CAPD), patient oneself can manually change dialyzate, and such as, every day can change 4 to 5 dialyzates; And for automatization peritoneal dialysis (APD), the equipment that one is referred to as circulating instrument (Cycler) can realize automatically changing dialysis tubing at night, thus patient can not be restricted on daytime.
In this kind of automatization peritoneal dialysis, abdominal cavity is filled dialyzate by circulating instrument, and fill volume needs control, provides maximum loading level to be such as about 3500ml for average adult to patient. Usually, a standard value can be adopted to be used as loading level, it is possible to avoid determining, by test, the complex work that loading level specific to each patient brings.
Usually, in peritoneal dialysis instrument, the conduit being inserted patient abdominal cavity by one inputs dialyzate, this dialyzate is before conveying is to patient abdominal cavity, suitable temperature (such as about 37 DEG C) need to be heated to, input, to patient, the uncomfortable sense that improper temperature (such as cross cold or overheated) dialyzate causes to patient to avoid. Therefore the dialysate temperature in dialysis tubing is extremely important treatment parameter, the monitoring of this dialysate temperature is especially important.
In the prior art, before being carried by dialyzate to patient abdominal cavity, it is heated by general employing heated tray, now can monitor with the temperature to dialyzate by set temperature sensor on heated tray. In the prior art, the scheme that a sensor is set can be adopted, in this kind of scheme, when the absolute value of the difference that the temperature T1 of the dialyzate detected when it over the course for the treatment of and default normal body temperature are worth between T is greater than predetermined threshold value (such as 2.5 DEG C), then can send guard signal. Owing to the duration of service of APD dialysis machine is long, and to security requirement height, once go wrong, very big harm can be brought to patient. Therefore this kind of the prior art monitors the technical scheme of dialysate temperature by single-sensor, cannot directly judge that whether this sensor is normal, potential risks can be brought to like this treatment of patient. Once this sensor is due to inner or external cause is malfunctioning, then cannot obtain the accurate temperature of dialyzate, very big harm can be brought to patient.

Wherein, described monitoring processing unit comprises further:
Non-treatment condition monitoring processing unit, for adopting the first monitoring logic corresponding with non-treatment state that the first temperature parameter and the 2nd temperature parameter are carried out monitoring process;
Therapeutic state monitoring processing unit, for adopting the two monitoring logic corresponding with therapeutic state that the first temperature parameter and the 2nd temperature parameter are carried out monitoring process;
Wherein, described therapeutic state monitoring processing unit comprises further:
Therapeutic state first compares unit, and whether the absolute value of the 2nd temperature parameter of the dialyzate that the first temperature parameter and the 2nd temperature sensor for judging the dialyzate that described first temperature sensor obtains obtains difference between the two is greater than the first threshold value,
First processing unit is that described absolute value is greater than described first threshold value for the judged result comparing unit at described therapeutic state first, then carry out instruction of reporting to the police;
Therapeutic state the 2nd compares unit, judged result for comparing unit at described therapeutic state first is that described absolute value is when being less than or equal described first threshold value, judge whether the absolute value of the difference of described first temperature parameter and a reference temperature preset is greater than Second Threshold, and whether the absolute value judging the difference of described 2nd temperature parameter and described reference temperature is greater than described Second Threshold;
2nd processing unit, is greater than described Second Threshold for the judged result comparing unit at described therapeutic state the 2nd for one of them absolute value, then carry out reporting to the police and point out the corresponding temperature sensor being greater than Second Threshold; If it is determined that result is two absolute values is all less than described Second Threshold, then proceed monitoring.
5. dialysate temperature monitoring device as claimed in claim 4, it is characterised in that, described non-treatment condition monitoring processing unit comprises further:
Non-treatment epidemic situation comparison unit, for when the working order residing for described peritoneal dialysis instrument is non-treatment state, whether the absolute value of the 2nd temperature parameter judging the dialyzate that the first temperature parameter of the dialyzate that described first temperature sensor obtains and the 2nd temperature sensor obtain difference between the two is greater than the first threshold value;
Non-treatment state processing unit, if the judged result of described non-treatment epidemic situation comparison unit is described absolute value is greater than described first threshold value, then carries out instruction of reporting to the police, otherwise proceeds monitoring.
6. dialysate temperature monitoring device as described in claim 4 or 5, it is characterised in that, described first threshold value is the twice of Second Threshold.
