Here, the living body contact gauze 1 is configured by laminating an adhesive portion 11, a gauze portion 12, an aluminum foil portion 13, and a release paper portion 14. Here, the gauze portion 12 is made of normal cotton. The sensor adhesive double-sided tape 2 is made of polyethylene resin.

FIG. 2 is an external view of a state in which the distal end portion of the sensor 16 for detecting body sound is attached to the hollow hole 4 of the probe gauze 100 for dialysis patient of the present invention shown in FIG. 1 and fixed to the arm 18 of the dialysis patient. It is. FIG. 2A is a diagram showing a state in which an antibacterial waterproof film 15 for preventing sensor rubber contamination is attached to the tip portion of the sensor 16, and FIG. 2B is a diagram in which the release paper portion 14 of the biological contact gauze 1 is peeled off. FIG. 2 is a diagram showing a state in which the probe gauze 100 for a dialysis patient is adhered to the arm 18 of the dialysis patient. In order to improve the followability of the skin shape, a gel-like substance or a jelly-like substance may be introduced between the sensor rubber (the exposed surface side of the sensor 16) and the antibacterial waterproof film 15 for preventing the sensor rubber contamination. The antibacterial waterproof film 15 for preventing sensor rubber contamination or the skin of the antibacterial waterproof film 15 for preventing sensor rubber contamination is used for the purpose of eliminating an air layer that attenuates body sound between the antibacterial waterproof film 15 for preventing sensor rubber contamination and the skin of the arm 18 of the dialysis patient. By applying a jelly-like substance, it is possible to detect biological sound more stably.

Here, the state of FIG. 2B is a state in which the dialysis patient probe gauze is in close contact with the dialysis patient's arm, and the dialysis patient probe gauze is disposed in the vicinity of the shunt of the patient's arm. The shunt sound applied to the patient or from the shunt is converted into an electrical signal by the sensor 16 and connected to a measuring device (not shown) via the signal line 17.

The aluminum foil part 1 of the biological contact gauze 1 is in close contact with the skin of the arm 18 of the dialysis patient and has an action of making the skin potential in the peripheral part of the sensor uniform, so that the sensor can stably output a biological signal. Contributes to collecting.

FIG. 3 shows correlation data between the intensity of the shunt sound and the blood pressure. The intensity of the shunt sound of the shunt formed on the dialysis patient's arm has a correlation with the blood pressure. This correlation data can be used to detect a decrease in blood pressure in a dialysis patient.
In other words, a predetermined shunt sound intensity is set as a threshold value by a determination device in the measuring instrument. Thereby, a decrease in blood pressure of a dialysis patient can be detected.
