Description

DETAILED DESCRIPTION OF THE INVENTION The field of industrial application and the disadvantages which the invention seeks to solve The present invention relates to a bladder puncture device according to the preamble of claim 1. Known cystocentesis devices include cannulation of a substantially cylindrical sleeve (Id;
One front face (5tirn 5eAte) is shaped like a blade, while the other front face is provided with a plastic handle. When such a cystocentesis device is inserted through the abdominal wall and into the bladder, a catheter tube can be inserted through the inner aperture of the sleeve and inserted into the bladder. After insertion of such a catheter tube into the bladder, the stub is withdrawn from the abdominal wall and then folded in two along a predetermined weak point through the handle. The two parts are easily removed from the catheter tube. This device removes urine (Uring) without guiding the catheter tube through the urethra.
) has the advantage of being able to be removed from the bladder, but has the disadvantage that it can only be used once and that the catheter tube may be damaged during intubation and cutting. Also, when force must be applied during intubation cutting, the tube may be accidentally pulled out of the body again.

Means for Solving the Problems The object of the invention is based on creating a cystocentesis device in which, while maintaining the advantages of the known arrangement, damage to the catheter tube is avoided. Furthermore, this tool can be used multiple times. This object is solved by the features specified in claim 1.

In principle, the cannulation according to the invention consists of two mutually pushable and mutually twistable sleeve parts, each of which is designed to allow the catheter tube to be removed through a longitudinal slit. It has a longitudinal slit with an aperture width of .

This longitudinal slit allows removal of the catheter tube when both of them overlap each other. Insertion of the cannulation into the bladder was accomplished by forcing the outer tape wall to cover the longitudinal slit of the inner sleeve, and at the same time allowing the inner sleeve wall to pass through the longitudinal slit of the outer sleeve. Twisted together to close the aperture.

For a detailed explanation of the present invention, one embodiment will be described below with reference to the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1 a cystocentesis device is shown having two mutually fitted sleeves 1 and 2. In FIG. In order to clarify the structure, the sleeves 1.2 are shown in a different position relative to each other. The lower front surface 3 of the outer sleeve 1 is formed in the form of a blade, the sharpness of which is improved by the oblique formation of this front surface 3. The front face 4 of the inner sleeve is likewise shaped like a blade and ends at an angle so that in the operating state both blades meet optimum cutting conditions. Each sleeve 1 or 2 is provided with a longitudinal slit 5 or 6, the width of which is selected such that the catheter tube 7 can be passed through this slit. The slit opening is rounded so that the catheter tube 7 is not damaged or damaged during removal. Sleeve 1,
The upper front face 9, 10 of 2 is bent in such a way that a handle 11.12 results. For operation aid, this handle 1
1.12 is provided with an angle 13.14, which is convenient for threading the sleeve. The handles 10.11 are arranged so that they overlap in the open state of the implement, the angles 13.14 being opposite in this case. The torsion of the sleeve is thus guided to the point of contact of the angle, and the two slit openings automatically overlap one another. There is therefore no need to check whether the sleeve is actually in the open position.

FIG. 2 shows a cross-section of adjacent walls of sleeves 1 and 2. This cross-sectional view shows the front surfaces 3 and 4 of both sleeves 1 and 2 in the cutting position to facilitate penetration of the abdominal wall. Since the cystocentesis device described up to now can be used again, a sterilizable material is selected for this device.

Stainless steel was used for this purpose.

The bladder devices described so far have at least 16 Char-r
ier (tCharrier is episode 0.3),
In particular, it allows the use of catheter tubes of different diameters, which are automatically coiled, thus resulting in little or no bladder wall damage. Both sleeves fit into each other in such a way that there is only a small intermediate space between them, so that the adipose tissue is not compressed. When using the device described so far, The cannula is inserted into the abdominal wall with a mutually twisted sleeve with a closed aperture, through which the cannula 7 is inserted, and after insertion of the tube 7, the cannula is withdrawn and both sleeves have their apertures opened. The sleeve is then easily separated from the catheter tube and provided for cleaning.
