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. It is a figure of the state which adhered the probe gauze 100 for dialysis patients to the arm 18 of a 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 portion 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 portion of the sensor uniform, so that the sensor stably outputs the 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.

This probe gauze for dialysis patients contributes to the smooth transmission of biological signals between the dialysis patient's arm and the sensor and eliminates noise. It can contribute to improvement.
