Description

Large Intestine Irrigation Probe

The technical field to which the utility model relates.

The utility model relates to medicine and can be used in colon surgery (coloproctology) when performing measures for the conservative resolution of tumor colonic obstruction.

State of the art

At present, in emergency surgery of the colon, when colon obstruction occurs due to the closure of the lumen of the colon by a tumor, the only effective method to remove stool from the colon and to resolve obstruction before surgery is an enema.

It is known the use of glass tips for enemas I. The disadvantage of this solution is also the low efficiency of the activities carried out using such tips.

Also known is a single-channel probe used for enemas 2 in order to clean the rectum and end sections of the colon from fecal contents. The disadvantage of this solution is also low efficiency due to the lack of tightness between the probe and the walls of the intestine, as well as the possibility of its rupture.

Utility Model Disclosure

The problem solved by the utility model is the creation of a probe that allows for efficient irrigation of the colon.

The problem is solved in that the probe containing the gastric canal and two injection channels isolated from each other, contain two

sequentially located flexible cylinders connected to the discharge channels

A useful medical and technical result from the use of the proposed solution is as follows: Consistent injection of 100 ml and 80 ml of saline into cylinders, respectively, into each cylinder, ensures a tight location of the probe in the rectum and a tight connection with the intestinal walls and prevention of water leakage from the rectum If it is impossible to enter the entire working part of the probe into the rectum, it is possible to carry out the procedure with the introduction of one balloon with injection of a smaller amount of fluid The sizes and volumes of the cylinders, the dimensions of the working part of the probe were selected empirically, based on the average anatomical sizes of the rectum. The sequential arrangement of the cylinders is due to the need to be in the mid-ampullar section of the rectum (first balloon) and lower ampullary section (second balloon). The anatomically rectum bends the frontal plane, therefore, between the cylinders a gap of 20 mm is made, which allows reliable fixation of the probe in the patient’s body

The length of the probe is 1400 mm in order to perform enemas, draining water into a container on the floor and not lifting the patient from the couch. This is very important for the convenience of the procedure, since many patients are weakened

The design of the probe allows you to perform both cleaning and siphon enemas

When the probe is located in the rectum, the tightness between the balloon (in the inflated state) and the inner wall of the rectum is achieved by ease of regulation of the volumes of fluid introduced into the balloon. The softness and elasticity of the materials used in the manufacture of the probe (silicone rubber) avoids injuries of the rectal mucosa when it is introduced

Brief Description of the Drawings

The utility model is illustrated in the drawing, which shows a diagram of a probe for irrigation of the colon.

Utility Model Implementation

The implementation of the utility model is disclosed by the example of a specific implementation of the probe

The probe is made in the form of a three-channel tube 1 made of silicone rubber (hardness 60-70 units Shore) with a length of 1400 mm and an outer diameter of 15 mm. On the working part with a length of 110 mm, two elastic working cylinders 2 and 3 are arranged in series with a distance between the cylinders of about 20 mm. For the convenience of introducing the probe in the idle (not inflated) state, the cylinders 2 and 3 have a diameter close to the diameter of the three-channel tube and exceed it by about 3-4 mm.

The injection channels of the probe are connected to a dilution unit having autonomous channels 5 for introducing liquid into the working cylinders 2 and 3. In the autonomous channels 5 there are control cylinders 4, which allow monitoring the status of working cylinders. The gastric channel 6 of the probe is designed to introduce fluid and irrigate the colon.

The probe is as follows.

The probe is inserted into the rectum of the patient to a length of 110 - 120 mm in the unblown state of the working cylinders 2 and 3. The fluid through the injection channel is supplied to the first working cylinder 2 in an amount of about 100 ml, while the balloon is inflated, fixed in the rectum. The mobility of the probe is controlled by a medical professional by applying a slight axial force (back and forth). Upon reaching fixation of the first balloon 2, that is, with a snug fit of its walls to the inner wall of the rectum, along the second injection channel

liquid is supplied (in a volume of up to 80 ml) into the second balloon 3, which provides even greater tightness of the probe-rectum contact.

Since the device is designed so that the working cylinders 2 and 3 can be located above and below the bend of the rectum - in the middle ampullar section (first working balloon 2) and lower ampullar section (second working balloon 3), the probe is securely fixed in the patient's body, preventing the leakage of fluid from the rectum with sphincter weakness.

Control cylinders 4 allow you to monitor the condition of the elastic cylinders 2iZ.

Then, liquid for irrigation of the colon (water, a solution of drugs, a decoction of medicinal plants, etc.) is supplied to the gastric channel 6 of the probe in the required volume (1 - 1.5 L) under the supervision of a medical professional, taking into account the patient’s well-being.

Then the gastric channel 6 of the probe is disconnected from the source of fluid without changing the position of the probe in the patient’s body, and the end of the probe is lowered into a container into which water with feces is poured. A sufficient probe length (up to one and a half meters) allows you to carry out the entire procedure without lifting the patient from the couch.

If necessary, the procedure is repeated as many times as necessary for a complete cleansing of the intestines from feces.
