Description

Technical Field

[0001] This utility model relates to the field of rectal electrode technology, specifically to a multi-channel myoelectric force conduction rectal electrode. Background Technology

[0002] Abnormal bowel movements caused by rectal and anal diseases typically manifest as chronic constipation, functional fecal incontinence, pain, and hypertonia, and these symptoms increase with age, significantly impacting people's daily lives. For example, patent CN116115902A discloses a rectal electrode probe for a pelvic floor electromyographic biofeedback therapy device. The rectal electrode includes a head electrode, a middle electrode, and a rear electrode. The head electrode is used to generate electrical stimulation on the rectal wall; the middle and rear electrodes are used to generate electrical stimulation on the puborectalis muscle and anal sphincter, and to collect electromyographic signals. Each electrode can independently adjust its frequency and current intensity to achieve coordinated movement training of the rectal wall, puborectalis muscle (anal canal), and external anal sphincter, as well as to achieve precise training. Patent CN103989468B discloses a rubber balloon corresponding to the rectal wall portion, with four electrodes on the surface of the rubber balloon. Each electrode is accompanied by a rectal pressure sensor, and multiple conductive electrodes are arranged in the anal canal portion.

[0003] Therefore, existing rectal electrodes can only collect or stimulate the puborectalis muscle (anal canal), rectal wall, and external anal sphincter, and transmit pressure signals between the device and the rectal wall. However, in clinical applications, constipation and bloating may also be caused by factors affecting the anal canal. Current technologies lack rectal electrodes that can simultaneously transmit pressure signals to the rectal wall, transmit pressure signals to the anal canal, and provide anal canal electrical stimulation.

These air guide tube groups are referred to as the first air guide tube group 14 and the second air guide tube group 15, wherein the first air guide tube group 14 is used to communicate with the anal canal balloon assembly 2. For pressure signal transmission, the second air tube group 15 is used to communicate with the rectal wall balloon assembly 1 to transmit pressure signals. The first and second air tube groups are only used to distinguish the air tube groups that transmit pressure signals supporting different areas, and do not limit the use of the same hardware structure for each air tube group. The anal tube balloon assembly 2 is provided with a conductive part corresponding to the location of the anal tube. The conductive part is connected to the electrode line, which is designated as the first electrode line 17 and the second electrode line 18.

A first conductive part 6 and a second conductive part 11, corresponding to the position of the anal tube, are respectively disposed at both ends of the anal tube balloon frame 3. The first conductive part 6 is connected to a first electrode wire 17, and the second conductive part 11 is connected to a second electrode wire 18. The second conductive part 11 is confined between the anal tube balloon frame 3 and the rectal wall balloon assembly 1. The anal tube balloon frame 3, together with the plastic body 7 assembled and docked with the end where the first conductive part 6 is located, positions and fixes the first conductive part 6. Both the anal tube balloon frame 3 and the plastic body 7 have positioning structures that cooperate with the first conductive part 6 on their end faces.

[0029] The end of the rectal wall balloon support 9 is connected to the anal canal balloon support 3 via a connecting frame 12. The connecting frame 12 and the rectal wall balloon support 9 are detachably connected via a snap-fit ​​structure. The second conductive part 11 is disposed between the mating surfaces of the connecting frame 12 and the anal canal balloon support 3. Both the connecting frame 12 and the anal canal balloon support 3 have positioning structures that cooperate with the second conductive part 11 on their end faces.

[0030] The positioning structure is used to limit the axial position of the corresponding conductive part 11. Therefore, in the embodiment of this utility model, the positioning structure adopts a stepped surface structure opened on the corresponding end face, and the stepped surface cooperates with the end face of the conductive part to perform axial positioning, thereby ensuring accurate transmission of electrical signals.

[0031] The plastic body 7 of this utility model adopts a hollow structure, forming a channel inside for the air guide tube assembly and the electrode wire connected to the conductive part to pass through. In order to maintain the stability of the position of the air guide tube assembly and the electrode wire inside the plastic body 7, a plastic plug 16 is provided at the end of the plastic body 7. The tubes and wires inserted inside are fixed by controlling the hole diameter of the plastic plug. A docking component for assisting structural docking is provided between the anal tube airbag skeleton 3 and the plastic body 7, and between the connecting skeleton 12 and the anal tube airbag skeleton 3. The docking component extends from one end to the other component, thereby realizing the docking assembly between the two components.

[0032] Based on the electrode structure disclosed in this utility model, multiple pairs of electrodes can be additionally set at the rectal electrode corresponding to the external rectal sphincter without departing from the design concept of this utility model, so as to transmit electrical signals of the external rectal sphincter.
