2. Description of the Related Art The abdominal wall and the abdominal organs of the human body are covered with the peritoneum. Since this peritoneum has the property of a semipermeable membrane, the peritoneum can be used as a dialysis membrane instead of the artificial dialysis membrane. A dialysis method applying this principle is called a peritoneal dialysis method (peritoneal perfusion method), and the peritoneal dialysate (peritoneal perfusate) is injected into the abdominal cavity by using the peritoneum in the human body as a dialysis membrane at the same position. The blood and lymph circulating in the peritoneum are dialyzed by allowing this to stay for a certain period of time. The continuous outpatient peritoneal perfusion method (CAP), which is attracting attention as a particularly powerful treatment method among the peritoneal dialysis methods, is described below.
D: Continuous Ambulatory Peritoneal Dialysis) will be described.

First, a catheter is inserted into the abdominal cavity by inserting a catheter into the abdominal cavity by puncturing a predetermined position of the abdominal cavity and then filling a dialysate bag filled with peritoneal dialysate whose components have been adjusted in advance and temperature adjusted. And connect with a tube. Here, this tube is provided with a tube clamp capable of blocking the peritoneal dialysate in the middle of the tube, and by closing the tube clamp, the dialysate bag is connected when the dialysate bag and the catheter are connected. Block peritoneal dialysate on the side.

Next, a dialysate bag filled with peritoneal dialysate is hung at a high place, the peritoneal dialysate is filled in the tube blocked by the tube clamp, and then the blocked tube clamp is opened. As a result, 2.0 l of peritoneal dialysate is usually injected into the abdominal cavity by utilizing the difference between the dialysate bag and the abdominal cavity. After the injection, the peritoneal dialysate is blocked on the abdominal cavity side by closing the tube clamp, and the empty dialysate bag and tube are wound up and put in the pants pocket or abdomen roll, etc. You can act.

Finally, after peritoneal dialysis is usually performed for 4 to 8 hours with the peritoneal dialysate injected into the abdominal cavity,
An empty dialysate bag is used as a drainage bag, which is hung or placed at a low place and the tube clamp is opened to drain the peritoneal dialysate injected into the abdominal cavity into the drainage bag. Note that these steps are continuously repeated with the above steps as a unit.

[0006] The above-mentioned CAPD has advantages that it can be carried out in a general home, activity during dialysis is free, dialysis procedure is simple, and cost is low, but on the other hand, peritoneal dialysate is retained in the abdominal cavity for a long time. Therefore, since peritonitis is likely to occur, it is necessary to constantly monitor the occurrence of peritonitis.

For example, when leukocytes are mixed in the drainage of CAPD, white turbidity occurs, and if there are leukocytes at a concentration of 100 cells / μl or more in the drainage, it is suspected that peritonitis occurs concurrently. , Patients, etc. visually confirm subjective symptoms and cloudiness in drainage, and if there are subjective symptoms or cloudiness in drainage, go to the hospital for a detailed examination. However, the turbidity of the drainage does not always occur due to leukocytes, but also due to the mixing of lipids such as triglyceride, it is difficult to judge whether the patient himself / herself has peritonitis. Therefore, even if white turbidity occurs in the drainage, it does not necessarily mean that it is pathological. Therefore, objectively judge the patient's state from the state of drainage,
There is a strong demand for a monitoring device that can reliably judge whether treatment is necessary or not.

Further, since the peritoneal perfusate is to be put into the abdominal cavity, it is required to be completely aseptic, and the drainage must be discarded without contacting the outside as much as possible. Although the amount of drainage differs depending on the osmotic pressure of the liquid used, the stagnation time, and the conditions on the patient side, it is usually 10 to 20% higher than the amount of injection. However, there is an exception only for the first time of one cool, and there is a considerable difference depending on the position of the tip of the inserted catheter. The amount decreases when the tip is in the shallow position of the abdominal cavity, and increases when it is in the deep position. However, since the remaining liquid fills this difference from the second time, it is usual to drain more than the injected liquid amount. The drainage weight serves as an index for whether or not the peritoneal dialysis is operated smoothly as described above, and also serves as an index for detecting an abnormality such as a decrease in the effective dialysis area due to adhesion of the peritoneum and clogging of the catheter.

Here, the weight measuring mechanism 40 comprises a strain gauge 40a and a strain measuring circuit 40b, measures the weight of the drainage, corrects it, and transmits the result to the microcomputer 50. The strain gauge 40a detects an error at the time of weight measurement due to the bias of the drainage bag inserted into the bag insertion portion 32, and corrects the error at the strain measuring circuit 40b to eliminate the error at the time of weight measurement of the drainage. Eliminate and anyone can use it to measure the weight of the drainage as accurately. Also, for example, if a drainage bag having a constant weight is used, or if the weight of an empty bag is measured and stored in advance, drainage is discharged by storing the weight of the empty drainage bag in advance. The weight can be easily corrected by subtracting the weight of the empty drainage bag from the weight of the drainage bag (the drainage bag filled with drainage).
