Abstract

The invention relates to a catheter comprising a member (1) that can be inserted into a person's rectum, said member including a first rear opening (11) that communicates with a first passage (12) for discharging bodily fluids from an aperture (13) at the front end of the insertable member (1). The insertable member (1) includes an expandable ring element (14) communicating with a second rear opening (15) for connection to an inflation device. The catheter includes a probe (2) disposed at the front end of a connection pipe (4), which pipe is housed in the first passage (12) and connected at the rear end thereof to a device (3) for supplying a pressurised liquid, said probe (2) including several holes (21) in the rear portion thereof for projecting the liquid backwards, cleaning the colon and pushing the probe (2) forwards.

Description

technical field [0001] The present invention relates to a catheter for performing image-based colonoscopy, and more particularly to a catheter capable of collecting bodily waste and insufflation of gas to dilate the colon. Background technique [0002] Currently, catheters are used to perform image-based colonoscopies. A common catheter comprises an insertable member insertable into a body cavity of a person, in this case the rectum, said member having a first insertable rear opening communicating with a first channel for drainage of bodily fluids, and connectable to at least one device for supplying gas into the body cavity of the individual through the opening at the forward end of the insertable member. The insertable part is provided with an expandable ring element adjacent to the front end, which communicates with the second rear opening of the insertable part through a second channel for communicating with an inflation device (the inflation device for an inflatable r...
