Description

[0001] The utility model relates to catheters, namely to a device for attaching a catheter tube to the body for draining urine.

[0002] In cases of extensive bladder cancer, such as carcinoma, where partial bladder preservation is impossible, surgeons resort to a radical solution: bladder ectomy (removal). In this procedure, one or both ureters are brought out onto the anterior abdominal wall. Special catheters are inserted into the resulting channel, such as a J-shaped polypropylene tube. One end has holes for draining urine from the kidneys, and the other has a special nipple for connection to a plastic bag into which urine flows from the catheter. As these bags fill, patients periodically drain the urine, thus replacing the natural function with medical means. Some J-shaped tubes contain fasteners for suture to the skin, while others do not have fasteners and are attached with medical tape.Both suturing to the skin and securing the tube with medical tape have various disadvantages. For example, when the tube retainer is sutured to the skin, a wet area forms underneath it, and the sutures cause pain when the catheter tube is pulled dynamically. When securing the tube itself with medical tape, prolonged brisk walking can cause the tape to loosen, causing the J-shaped polypropylene tube to slip out, eventually causing it to fall out completely. The instability of this type of attachment is due to the tape significantly losing its adhesive properties after two to three days due to sweat and skin movement. The adhesive layer's adhesion to the smooth polypropylene tube weakens, leading to the tube slipping out.

[0003] A device (CN210205054 (U) - 2020-03-31) of a permanent fixation support used after ureterostomy is known, in which the upper part of the stent body is provided with a fixation frame, the lower part of the stent body is provided with a support frame, the fixation frame is petal-shaped or bottle-hole-shaped, the entire support frame is barrel-shaped, the four ring walls are mesh-shaped and are compressed in the axial direction of the support frame after being pressed, and the lower part of the support frame is a curved arc.

[0004] The disadvantage of this solution is its complexity and the fact that it does not include a urine drainage tube.

[0005] J-shaped ureterocutaneostomy tube catheters are known, the disadvantage of which is the need to sew the fastening element of the J-shaped tube to the skin.

[0006] The technical objective of the claimed solution is to simplify the design while increasing the reliability of attaching the catheter to the body.

[0007] The technical result of the claimed solution is the use of a device for attaching a tube to the body.

[0008] The specified technical result is achieved in that a device for attaching a catheter tube to a body for draining urine is proposed, comprising a housing made in the form of a plate with one side of which a groove is made for placing a catheter tube in it, while a clamp for fixing the catheter tube is placed on the housing, and the entire device is made with the possibility of attaching to the skin by means of a medical patch, the clamp for the tube is made in the form of a plate placed on the housing, the clamp for the tube is made in the form of a clamp, while in the center of the housing there is an opening for placing a clamp in it, tightening the tube, the groove on one of the sides is made with a bend from its axis at an angle of α = 25-40 degrees, one of the sides of the clamp, in contact with the tube, is covered with an abrasive layer.

[0009] Figure 1 shows a general diagram of a device for attaching a catheter tube to the body for draining urine, in which the clamp is made in the form of a plate.

[0010] Figure 2 shows a general diagram of a device for attaching a catheter tube to the body for draining urine, in which the clamp is made in the form of a collar placed in an opening in the body plate.

[0011] Figure 3 shows a diagram of a device for attaching a catheter tube to the body for draining urine with a clamp in the form of a plate, in which a medical patch is attached to the entire structure.

[0012] Figure 4 shows a general diagram of the device for attaching a catheter tube to the body for draining urine with a clamp in the form of a clamp, in which a medical patch is attached to the entire structure.

[0013] A device for attaching a urinary drainage catheter tube to the body comprises a housing in the form of a plate with a groove (3) formed on one side and containing a tube secured with a clamp. The tube clamp is formed as a plate (4) mounted on the housing. In another embodiment, shown in Fig. 2, the tube clamp is formed as a clamp (5), with a hole formed in the center of the housing for accommodating the clamp, which tightens the tube.

[0014] The device works as follows: after connecting the J-shaped polypropylene tube to the ureter cavity brought out to the abdominal wall, at a sufficient distance from the place of entry into the abdominal wall, the tube is placed in the groove of the body of the flat element (plate), made with a bend, secured with a clamp, then a medical patch - 6 of a given size is attached on top of this entire structure and the skin located around it, the adhesive force of which exceeds the tensile force of the tube with a filled urine bag.
