Field of the Invention The present invention relates to an artificial dialysis device used for treating patients with renal failure or the like for the purpose of removing waste products in blood. By continuously measuring the amount of liquid containing waste products that are continuously dialyzed from blood during dialysis, that is, the amount of ultrafiltration, it is possible to know the progress of dialysis and the total amount of ultrafiltration, and The present invention relates to an artificial dialysis device equipped with an ultrafiltration amount measuring device for performing dialysis.

It is known that artificial dialysis is carried out by removing the waste products in the blood and then returning it to the body. The purpose of artificial dialysis is to remove waste products from the blood of patients with renal failure, etc., but conventionally, from the experience of doctors, dialysis is performed for a sufficient fixed time, for example, for 5 hours with a constant flow rate at the dialysate inlet. The purpose was achieved by this.

一定時間、例えば５時間の間透析は継続される。As an example of an artificial dialysis device according to the conventional method, a device having a structure shown in FIG. 3 is known. FIG. 4 is a schematic diagram showing the structure of the dialyzer. Blood guided from the blood vessel of the patient 1 is sent to the dialyzer 3 by the pump 2. At this time, the dialysate is also sent from the dialysate tank 4 to the dialyzer 3 by the dialysate pump 5.
The flow rate of the dialysate at this time is adjusted to a predetermined fixed amount by the adjusting flow meter 6. In the dialyzer 3, the blood 8 entering from the blood inlet 7 flows to the respective blood outlet 12 and dialysate outlet 13 with the dialysate 10 entering from the dialysate inlet 9 and the dialysis membrane 11 separated. At this time, the waste products in the blood 8 are dialyzed into the dialysate 10 contained in the ultrafiltrate 14 and discharged, and are discharged as waste liquid 15 through the dialysate outlet 13. Dialysis is continued for a certain period of time, for example, 5 hours, until waste products in blood 8 are sufficiently removed.

いという欠点がある。By the way, in such a conventional artificial dialysis apparatus, it is not possible to adjust the dialysate inlet side flow rate and the blood inlet side flow rate to the dialyzer to a predetermined fixed amount at the start of dialysis. However, there is a drawback in that the amount of ultrafiltration that is drained from the patient's blood is not monitored at all.

る。[0006] The total amount of ultrafiltration that is slowly drained from the patient during dialysis treatment is very important for dialysis treatment, and too little or too much burdens the patient. That is,
If the amount is too small, the blood waste will not be sufficiently removed, and the blood waste will increase in concentration by the time of the next dialysis treatment, resulting in a uremic condition. On the other hand, if the amount is too large, the concentration of low molecular weight substances in blood, such as electrolytes and blood sugar, will decrease, and side effects such as fever and chills will occur during dialysis.
In the conventional method, the dialysis time is set based on the experience of a doctor, and the amount of ultrafiltration cannot be monitored during dialysis.

It is easy to make the output voltage characteristics the same, and since each flow rate detector is affected by the change in the magnetic field in the same way even when the magnetic field changes, it can be obtained as the difference between the outputs of the flow rate detectors. It does not affect the amount of ultrafiltration. Therefore, a stable ultrafiltration amount can be continuously output during dialysis (about 4 to 5 hours).
