RU63686U1 - DRAIN PIPE - Google Patents

Abstract

The utility model relates to medical equipment and can be used in surgery, urology, cardiovascular surgery, gynecology, neurosurgery for drainage of cavities and hollow organs. The objective of the utility model is to create a drainage tube that provides for a long time a continuous outflow of biological fluids from organs and cavities and reduces the traumatic effect on adjacent tissues. The drainage tube is made of elastic material and contains in the tube of a larger diameter a freely placed tube of a smaller diameter. The new fact is that at the working end of the tube of a larger diameter in the area placed in the drainage zone, a spiral incision in the form of a groove is made around the circumference of the tube. The cut is made with a step of spiral turns not smaller than the diameter of the tube. Atraumatic rounding is made at the end of the spiral tape formed by the cut.

Description

The utility model relates to medical equipment and can be used in surgery, urology, cardiovascular surgery, gynecology, neurosurgery for drainage of cavities and hollow organs.

Known drainage tube [1], containing side holes made of absorbable material. Depending on the function performed, the place of application and the required specified period of stay in it, a tube of the desired length, wall thickness, diameter is selected. The drainage tube can be in the ducts and organs for a long time, while remaining in working condition. Under the action of hydrolysis, the tube completely resolves after 10-45 days.

The disadvantage of the tube is its rigidity, which is why traumatic effects on tissues in the area of its location are possible.

Also known is a drainage tube [2] made of an elastic material and containing a freely placed tube of a smaller diameter in a tube of a larger diameter. The tube has a T-shape and is made of two L-shaped tubes of various diameters inserted one into the other. Each of the tubes has openings on the outside of the bend angle. This drainage tube can be used for Keru T-shaped drainage. It allows you to eliminate tissue trauma during its removal.

The disadvantage of the tube is due to its rigidity, as a result of which, being in the drained cavity, it can cause painful sensations by pressing on adjacent tissues when the patient is moving.

The objective of the claimed utility model is to create a drainage tube that provides for a long time a continuous outflow of biological fluids from organs and cavities and reduce traumatic effects on adjacent tissues.

The technical result from the solution of the task is:

- to accelerate the healing of wounds and the prevention of postoperative complications due to the effective outflow of biological fluids and the removal of clots and pieces of tissue;

- in the effective supply through the inner tube of pharmaceuticals needed for treatment;

- in reducing the stress load experienced by the patient in the postoperative period, due to the reduction of pain due to the soft contact of the tube with adjacent tissues.

The essence of the utility model is as follows.

The drainage tube is made of elastic material and contains in the tube of a larger diameter a freely placed tube of a smaller diameter.

The new fact is that at the working end of the tube of a larger diameter in the area placed in the drainage zone, a spiral incision in the form of a groove is made around the circumference of the tube. The cut is made with a step of spiral turns not smaller than the diameter of the tube. Atraumatic rounding is made at the end of the spiral tape formed by the cut.

The drawing shows the inventive drainage tube.

In the outer tube of larger diameter 1, an inner tube of smaller diameter 2 is installed. Both tubes are made of an elastic material, for example, silicone. Openings 3 are made in the tube 2. At the end portion of the tube 1 placed in the drained cavity, a through spiral groove 4 is made. Atraumatic rounding 5 is made at the end of the spiral tape formed by the cut.

Thanks to the spiral cut, the tube 1 bends in any direction from light exposure. In the process of drainage during bending of the spiral section, the groove 4 is constantly open, and in curved places it can become somewhat wider. This contributes to the ingress into the tube 1 of almost all clots and torn away tissue particles and their removal to the outside. In addition, the outflow of biological fluid is facilitated by the supply of disinfectant and therapeutic pharmaceuticals through the tube 2. Due to the spiral section, the tube is more gently in contact with adjacent tissues, reducing the traumatic effect and pain. Effective drainage accelerates wound healing.
