Description

Intestinal probe for monitoring abdominal pressure and electrical stimulation of the duodenum in the postoperative period

The utility model relates to medicine, in particular to abdominal surgery, namely, designs of probes for intubation of the small intestine.

A known probe for intraintestinal electrical stimulation, made in the form of a tube of flexible, biologically neutral material and two electrodes, in which an electrode (anode) is sealed to the distal end is an olive (metal tip), to which an electric conductor is brought out from the probe’s lumen, which is brought out to connection to the first output of the stimulating current source, characterized in that the second electrode (cathode) is made in the form of a tube with a spherical middle part and is installed in a transverse section of the probe oyanii ^~ 650 mm from the distal end, wherein the spherical portion of the second electrode extends above the surface of the probe at 0.5-1.5 mm and the second conductor from the second output of the stimulation current source is connected to the inner wall of the second electrode, in addition, the walls of the probe symmetrically located drainage holes are made along its length. (RU 48785, 11/10/2005)

A device for circular sounding of the intestine. The invention relates to medicine, namely to surgery. The essence of the invention lies in the fact that the device is made in the form of two PVC tubes: a guide with a diameter of 0.9 cm, having on the inner surface every 30 cm an electrically conductive sealing ring connected to a monopolar electrode, and both ends of the tube are closed with foam rubber circular couplings, and the distal end has an evacuation tube for connection to a vacuum pump, and a working tube with a diameter of 0.5 cm and marks every 10 cm, located inside the guide, which has two restrictive valves (rubber pads on the outer wall of the working tube) between which there is an electrically conductive restriction valve (rubber cuff with a bulb connected by an electrode). Between two different valves in one gap there is a hole for supplying a medical solution, in the second - evacuation holes. A special locking device is provided for connecting the ends of the working tube. The use of this probe allows circular intubation of both the small and large intestines, the evacuation of intestinal contents, the fragmentary administration of drug solutions with a uniform distribution along the length of the intestine, and the intra-intestinal electrical stimulation. (RU 2104054,10.02.02.1998).

A known probe for intubation of the intestine in the form of a tube with holes, characterized in that the proximal end of the tube is made smoothly oval, with a diameter of 5 / 3-3 / 2 and a length of 1 / 4-1 / 5 with respect to the diameter and length of the distal part of the tube, at the proximal end of the tube, the oval holes are located in two planes in parallel, and on the distal part of the hole are located in three planes in a checkerboard pattern. (RU 106116, 08/08/2011)

The objective of the utility model is to develop a more advanced probe design that would allow for less traumatic intubation of the intestine and facilitate the passage of the probe through the small intestine.

The solution is achieved by the fact that the intestinal probe for monitoring intra-abdominal pressure and electrical stimulation of the duodenum in the postoperative period, characterized in that it is made in the form of a tube with side openings located in a checkerboard pattern and contains a cuff for filling with liquid at the proximal end of the probe, a microirrigator for cuff filling, distal to the cuff on the probe wall are coils of copper wire, consisting of two groups of coils 5 cm long, located at a distance and 3 cm from each other, made with the possibility of connecting to an electrostimulation apparatus, while at the distal end of the probe there are inflated cuffs in the form of two olives located at a distance of 3 cm from each other, and a micro-irrigator for inflating cuffs in the form of two olives.

The technical result is a more advanced probe design, which allows for less traumatic intubation of the intestine, to facilitate the passage of the probe through the small intestine, to conduct electrical stimulation of the duodenum and to monitor intra-abdominal pressure.

The essence of the utility model is illustrated in the drawing, which shows a General view of the probe. FIG. one.

The probe consists of:

1 - Cuff (capacity) for filling with water and measuring intra-abdominal pressure

2 - Microirrigator for inflating cuffs 3

3 - Inflated cuffs

4 - Microirrigator to fill the cuff with water 1

5 - Coils of thin copper wire on the probe wall, connected to the electrical stimulation apparatus.

The probe performs frame and decompression-detoxification functions, can be used to prevent intestinal paresis and for enteral tube feeding in the postoperative period.

The operation of the device is as follows.

Before starting the probe, the anesthetist controls the cuff extension of the endotracheal tube and empties the stomach to prevent aspiration of the contents into the airways. Next, a coordinated and synchronous advance of the probe along the gastrointestinal tract in the distal direction is carried out due to pressure along its axis in the usual way using a thickened short part of the probe 1. This allows monitoring the progress of the probe through the pyloric pulp and duodenal horseshoe into the small intestine . Further advancement of the probe in the small intestine is facilitated by bloated olives, which allow the small intestine to be fixed and the probe to be easily advanced in the lumen of the small intestine. Decompression-detoxification, skeleton function and enteral nutrition are carried out using the main silicone tube.

An intestinal probe, in the form of a tube with side holes in a checkerboard pattern, is inserted into the intestine, at the distal end (terminal part) of the probe, inflated cuffs in the form of two olives, located 3 cm apart, filled through the microirrigator 2 facilitate the passage of the probe through the small intestine, after installing the probe, the cuff for measuring intra-abdominal pressure, filled with microirrigator 4, is located in the stomach, below (distal) the cuff (capacity) for measuring intra-abdominal pressure, after installing the probe, coils of thin copper wire ki on the wall of the probe connected to the unit of electrical stimulation are in the duodenum.

The determination of intra-abdominal pressure is carried out by using the wall of the container as an elastic membrane that transfers intra-abdominal pressure to a liquid, which is in the volume of 10-12 ml in its cavity at zero pressure. The maximum capacity of the container, provided that atmospheric pressure is maintained in it, is 15-16 ml. This difference of 4-5 ml makes it possible to completely eliminate the pressure of the vessel wall on the liquid, which is extremely important in determining the true value of intra-abdominal pressure.

A liquid in a volume of 10-12 ml (saline) is poured into the container or at the end of the operation. For visual measurement accuracy, the liquid is slightly tinted with brilliant green. The most convenient means of measurement is a transparent capillary and a ruler. A measurement value of zero is set at the mid axillary line. To implement this method, any drainage tube, including a standard silicone, with a diameter of 8.5 mm with a cuff, can be used.

The proposed probe design allows to facilitate intubation of the small intestine, to conduct electrical stimulation of the duodenum in order to combat paresis of the small intestine, and to monitor (measure) intra-abdominal pressure in the postoperative period.
