Electrode device for stimulating anal canal and rectum

Abstract

The invention provides an electrode device for simulating the anal canal and the rectum. The electrode device for simulating the anal canal and the rectum comprises a rubber balloon used for being placed in the rectum of the human body, the surface of the rubber balloon is provided with four electrodes, a rectum pressure sensor is arranged besides each electrode, the rear end of the rubber balloon is provided with a cylindrical sponge body which corresponds to the anal canal position of the human body and is used for fixing and supporting, the cylindrical sponge body is provided with one or more ring-shaped electrodes, a corresponding anal canal pressure sensor is arranged besides each ring-shaped electrode, a supporting guide tube is arranged inside the rubber balloon and the cylindrical sponge body in a penetrating mode, and a ventilating tube for inflating and deflating of the balloon is arranged inside the supporting guide tube. Each electrode is connected with a motor control wirer, each rectum pressure sensor is connected with a signal transmitting wire, a ring-shaped electrode control wire is led out of each ring-shaped electrode, a signal transmitting wire is led out of each anal canal pressure sensor, and all the control wires and the transmitting wires form a wiring harness, and the wiring harness is led out of the supporting guide tube.

Description

technical field [0001] The invention relates to a medical detection device, in particular to an anal canal and rectal double-stimulation electrode device designed for human anal canal and rectal sensory function detection. Background technique [0002] In the known technology, the current detection of human rectal sensory function is mainly through anorectal pressure measurement, which evaluates the human rectal maximum tolerance, initial threshold, defecation threshold, etc., thus indirectly reflecting the human rectal sensory function . At present, the electrodes used for neurophysiological detection on the market are mainly divided into surface electrodes, needle electrodes, disc electrodes, etc., but these electrodes cannot be used for stimulation in the digestive tract, which affects the detection of sensory function of the digestive tract by clinicians. Contents of the invention [0003] Purpose of the invention: The existing problem to be solved by the present inve...
