Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to medical devices, and more particularly to colon cleansing devices.

The present invention is useful in the treatment of paresis or paralysis of the intestine, in important procedures for emergency preoperative treatment of the colon, in post-operative and postoperative cardiac surgery patients prone to constipation in a state of decompensation before surgery. It has been found to have wide application in patients suffering from paralysis of the pelvic organs as well as in patients suffering from paralysis of the pelvic organs.

[Conventional technology]

Devices for colonic cleansing or evacuation are widely known in the art. In other words, it is a cleaning or evacuation promoting enema device.

However, since this method is performed without monitoring the internal state of the intestine, the colon cannot be sufficiently cleansed even with such an enema device. Additionally, this procedure is accompanied by intense patient tension.

Other prior art devices for cleaning the colon include:
consisting of a cylindrical envelope with a circular end, the envelope having a discharge channel and a suction channel, both of which are separated from each other;
Each has an opening in the distal part of the jacket, and each reservoir and receiver of the cleaning solution is connected via its own pipe with the discharge channel and the suction channel, respectively, which are connected to the discharge head and the suction channel for the discharge and suction liquid. By means of such a device (see SU, A, 806,040) it is possible to adjust the ejection head and suction head of ejection and suction liquids, respectively. However, the colon cleansing process with this device is unsupervised, as mentioned above, and the amount of cleansing solution injected into the colon cannot be controlled by measuring the internal pressure of the intestine; The irrigation solution is introduced into the colon in an instrumented manner only, without the need for irrigating fluid, and the flow rate of the irrigation solution is adjusted without having to match the volume of feces.

Furthermore, the known devices are of rigid construction and do not allow adequate irrigation of the distal portion of the colon.

[Problem that the invention seeks to solve]

The main and essential object of the present invention is to provide a colon of a structure which allows both the central and distal portions of the colon to be adequately evacuated and the flow rate of the irrigation solution to be adjusted to suit the internal conditions of the colon. The object of the present invention is to provide a device for cleaning.

[Means for solving problems]

The essence of the invention is a colonic irrigating device, which consists of a cylindrical jacket with an oval end, which has an ejection channel and a suction channel separated from each other, and in the end part of the jacket. It comprises an opening, a cistern for cleaning solution, and a receiving cistern, the cistern being connected via a pipe to the discharge channel, while the receiving cistern is connected via another pipe to the suction channel, thereby discharging the liquid to be discharged and aspirated. The head and the suction head are respectively adjusted, the jacket is made of elastic material, the endoscope is in the suction channel, the actuating part is at the end of the jacket, and the transparent inflatable balloon is inserted into the endoscope. It is attached to the working part of the mirror.

In order to monitor the pressure inside the intestine, a capillary tube is placed in the discharge channel, one end of which is open and exits through an opening in the distal part of the envelope, while the other end of this capillary tube is connected to a cylindrical outside. Connect to a pressure measuring device outside the cover.

The discharge path 2 leads to a water tank 5 for cleaning solution via a pipe 4, which is equipped with a scale 6 for reading the amount of liquid discharged from the water tank, and is further fitted with an electric heater 7 and a thermometer 8. ing.

The suction channel 3 connects via a pipe 9 to a receiving tank 10, which is fitted with a tightly sealed cover 1) and contains a tube 12 with an inflatable rubber valve 13, and furthermore A reservoir scale 14 indicating the amount of liquid in the receiving tank 12 is provided. A variable displacement pump I5 is attached to the pipe 4, and a variable displacement pump 16 is further assembled to the pipe 9. An endoscope 17 is attached to the suction channel 3 (FIG. 2.3), the working part 18 of which extends out of the oval distal opening of the jacket 1 with a hermetic seal;
It is connected to a transparent inflatable balloon 19 which provides an air tube for putting excessive pressure into the balloon 19.

An internal septum 20 is attached to the end region of the envelope, while an opening 21 (Fig. 2.3.4) is made in the suction channel 3 near the septum 20, for receiving the colonic contents. The discharge channel 2 and the septum 20 are opened, and the discharge connectors 22 are attached thereto (four in this embodiment), and the distal opening 23 (
4), the openings 23 of which extend evenly over the terminal surface to the jacket. The suction channel 3 (FIG. 3) has a circular cross-section, while the outlet channel has a slit-shaped cross-section, the ratio of the cross-sectional areas of the channels 2 and 3 being 3:1.

In a preferred embodiment of the invention, the discharge channel 2 leads to a capillary tube 24, one of whose ends is open and which leads out through an opening 25 at the distal end of the jacket, the other end of which is open. It is connected to a pressure measuring device 26, for example an electric manograph.

This colon cleansing device operates as follows.

The elastic sheath 1 is inserted into the rectum and pressure is applied to the inflated transparent balloon 19 to prevent feces from entering the operating area of the endoscope 170 and visually monitor the movement of the colon and the sheath 1 therein.

2 and an opening 23 to send a cleaning fluid into the colon. The flow strength (flow rate) of the cleaning solution is adjusted in the range of 100 to 2000 m/min depending on the concentration of feces.

Due to the small diameter of the discharge opening 23, a strong cleaning action is obtained.

Electric heater 7 controls the preset temperature of the cleaning solution.
and monitored by a thermometer 8, while the flow rate of the cleaning solution is read from a scale 6.

The flow rate of the fluid drawn from the colon through the opening 21 into the channel 21 and along the pipe 9 into the receptor 10 is regulated by the pump 16 according to the pressure value in the intestine, which pressure The measurement is performed by an electromanograph connected to the capillary tube 24 extending into the opening 25 of the tube. The pump 16 dampens the pulsations within the colon and thus prevents the end of the envelope l from being sucked into the colon wall. The flushed faeces and gases are conveyed through pipe 9 to a receptacle 10 which is tightly closed with a cover 1) comprising a tube 12 with a rubber valve 13 fitted onto it; Expands with gas carried from the colon. The amount of wash water is indicated on scale 14. At the same time as the colon is evacuated, the mucosa of the colon is examined with an endoscope.
