Problems solved by technology

This method judges the intention to defecate only based on the information of the intestinal pressure, and the misjudgment rate is high. In addition, when the intestinal contents are of different types (solid, liquid and gas), the system cannot judge the specificity of the excretion through the intestinal pressure information. type
[0006] In summary, although the implantable artificial anal sphincter can help patients with anal incontinence to achieve bowel control, the existing system cannot meet the needs of patients for sensing intestinal contents

Embodiment 1

[0034] Such as figure 1 As shown, this embodiment includes: motor drive mechanism 1, upper fixing mechanism 2, lower fixing mechanism 3, middle swing arm 4, intestinal flexible pressure sensors 5, 6, 7, 8, infrared transmitter 9, infrared receiver 10 .

[0035] In the present embodiment, there are 4 intestinal flexible pressure sensors, and the number of sensors in the specific application is not limited to 4, which are respectively arranged on the middle swing arm 4 of the artificial anal sphincter actuator, the inner wall and the upper layer of the upper and lower two-layer fixing mechanisms 2 and 3 The upper surface of the fixing mechanism 2 is bent into a semi-circular shape, and fits closely with the intestinal tract.

[0036] The infrared emitter and receiver are a pair, and in this embodiment, they are arranged on the inner wall of the upper fixing mechanism 2 of the artificial anal sphincter actuator, and the emitter and receiver are respectively arranged at opposite po...

Abstract

A system and method for detecting content in intestinal tract based on flexible pressure transducers and infrared detection. The system comprises an artificial anus sphincter execution mechanism, a plurality of flexible pressure transducers used for acquiring the pressure of intestinal tract, an infrared transmitting and receiving device, a pressure information processing module and a microcontroller. The flexible pressure transducers are arranged in the inner wall of the artificial anus sphincter execution mechanism and tightly cling to the surface of the intestinal tract, and the flexible pressure transducers are used for acquiring the pressure of the intestinal tract. The pressure information processing module is used for acquiring the pressure of the intestinal tract and then transmitting to the microcontroller. The microcontroller is used for outputting start instructions to the infrared transmitting and receiving device after receiving and determining the pressure of the intestinal tract, and receiving intensity information of infrared signal transmission so as to determine content type information. The microcontroller is used for calculating the quantity of content in the intestinal tract based on the intestinal tract pressure information, and transmitting the intestinal tract pressure information and the content type information out of the body so as to reestablish a defecate perception system.

Description

technical field [0001] The invention relates to a system in the technical field of gastrointestinal medical devices, specifically a flexible pressure sensor and an infrared detection head embedded in the artificial anal sphincter mechanical arm to detect the type and quantity of intestinal contents system. Background technique [0002] Anal incontinence means that the anal sphincter loses the ability to control the excretion of feces (solid, liquid and gas), which belongs to a kind of defecation disorder, which seriously interferes with the normal life and work of patients, and has a huge impact on the patient's body and mind. Unhealthy lifestyle, increasingly prominent social aging and rising mental pressure, anal incontinence has become a social problem that cannot be ignored. The existing conventional treatment method is mainly colostomy, which has poor therapeutic effect, easily causes complications, and seriously affects the quality of life of patients. The implantabl...
