Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and in particular to an intestinal deformable bidirectional bioelectric signal conduction device that is easy to clean. Background Art

[0002] Replicating animal experimental models in the intestine and biopsy sampling of the patient's intestinal mucosa generally cause invasive damage to the intestine, and the location and range of the lesions are limited and inaccurate, and multiple sampling will cause the damage to the affected area to worsen. Postoperative observation and prognosis also require secondary invasive damage, which causes multiple injuries to both experimental animals and patients. The utility model with announcement number CN210228126U relates to an intestinal deformable bidirectional bioelectric signal conduction device, including a pipeline portion, an inflatable balloon, a bidirectional guide electrode, a detachable power supply and a storage chip; an inflatable balloon is installed on the pipeline portion, and a bidirectional guide electrode is installed on the inflatable balloon... It can be placed in the body of an experimental animal or patient for a long time, on the one hand, dynamically monitor the electrophysiological activity of the intestine, and on the other hand, release stimulation signals to intervene in the electrophysiological activity of the intestine. It is easy to clean and will not cause invasive damage to experimental animals and patients.

[0003] However, feces will be collected in the pipe portion of the hollow tubular structure of the device. Since the pipe portion of the hollow tubular structure is deep, it is inconvenient to clean the feces in the pipe portion of the hollow tubular structure after use. Therefore, in order to solve the above problem, the patent with publication number CN214807909U has been further designed. The device includes fixing the cylindrical plastic bag in the annular groove through an arc-shaped pressing block, and using the expansion force of the inflated balloon to reinforce the cylindrical plastic bag again. At this time, the card block is engaged with the card slot, and the cylindrical plastic bag will not fall off when it is taken out. The card block and the card slot can be released by pressing the pressing plate, and the cylindrical plastic bag can be taken out.

[0004] Although the above design can facilitate the cleaning of the deformable bidirectional bioelectric signal conduction device, its design structure is complex. When installing the cylindrical plastic bag, the bag mouth needs to be folded over and stuffed into the inside of the annular groove, which is not convenient for the quick fixation of the cylindrical plastic bag. At the same time, the head of the device still needs to be cleaned. Therefore, a new design is proposed to address this problem. Utility Model Content

At the same time, after the bidirectional guiding electrode 3 is in close contact with the intestinal wall, it can guide the current to stimulate the intestinal wall, and then collect the bioelectric signals emitted by the intestinal wall, and transmit the collected bioelectric signals to the storage chip 4. The bidirectional guiding electrode 3 is connected to the storage chip 4 signal, and the inflatable balloon 2 is connected to the surface of a plurality of bidirectional guiding electrodes 3, one end of the hollow pipe 1 is detachably connected to a detachable power supply 5 with a storage chip 4, and an annular fixed end head 8 is fixed to the end of the hollow pipe 1 away from the detachable power supply 5, and the outer surface of the annular fixed end head 8 is provided with a fixing sleeve 6 for fixing the opening of the plastic bag 7 so that the opening of the plastic bag 7 is located between the fixing sleeve 6 and the annular fixed end head 8 to achieve clamping and fixing. The plastic bag 7 is arranged inside the hollow pipe 1, and excrement can directly enter the plastic bag 7 without contaminating the inner wall of the hollow pipe 1. A quick connection component is provided between the fixing sleeve 6 and the annular fixed end head 8, and an alignment mark is provided between the inflatable balloon 2 near the position of the fixing sleeve 6 and the fixing sleeve 6.

[0027] The fixing sleeve 6 is made of medical plastic and is a disposable material. It can be discarded after each use without dirtying the end of the device. The outer edges of the fixing sleeve 6 are all curved and smooth, which is conducive to pushing it into the anus. The quick connection component includes at least two groups to achieve uniform fixation. The quick connection component includes a clamping head 801 fixed on the outer surface of the annular fixing end 8. The outer inner wall of the fixing sleeve 6 is provided with a vertical slide groove 601, a horizontal slide groove 602 and a bayonet 603.

When in use, the clamping head 801 first slides into the vertical slide groove 601. At this time, the first positioning mark 9 is aligned with the alignment mark 11. Then the fixing sleeve 6 is rotated so that the clamping head 801 slides into the horizontal slide groove 602. When the second positioning mark 10 is used to align the alignment mark 11, the clamping head 801 enters the bayonet 603 to complete the connection.

[0029] During specific use, first place the plastic bag 7 into the hollow tube 1, and fold the opening of the plastic bag 7 to the outer surface of the annular fixed end 8, then align the fixing sleeve 6 with the clamping head 801 and put it on, and rotate the clamping head 801 to enter the inside of the clamping mouth 603, so that the opening of the plastic bag 7 is located between the fixing sleeve 6 and the annular fixed end 8, then the hollow tube 1 can be inserted from the anus, and the inflatable balloon 2 can be inflated, so that the bidirectional guiding electrode 3 is in close contact with the intestinal wall, guides the current to stimulate the intestinal wall, and then collects the bioelectric signals emitted by the intestinal wall.
