Description

Catheter securing device

The present invention relates to a catheter fixation device, and more specifically, to allow a drainage catheter to be positioned between a pair of fixing parts made of silicone, so that the drainage catheter is less affected by the patient's position change, and It is characterized in that it is possible to prevent complications such as infection caused by folding of the drainage catheter due to the change in position.

The urine produced by the kidneys due to the obstruction of the urinary tract of the patient cannot be discharged to the urethra through the ureters and ducts, causing back pain, fever and uremia. In this case, a percutaneous nephrostomy (PCN) is performed in which a drainage catheter is inserted into the kidney through the skin to drain urine directly from the kidneys out of the body.

First, after passing through the skin with a thin needle and going to Shinwoo, a thin guide wire is inserted and replaced with a thicker guide wire. After several path extension procedures, a drainage catheter is inserted into the pyelone and the part that comes out of the body is fixed to the skin using a separate fixing device. Thereafter, a drainage bag (hereinafter, a drainage bag) is connected to allow urine to be discharged by itself.

At this time, when the patient is lying on the side of the bed near the back on the insertion position of the drainage catheter, the drainage catheter frequently collapses or falls out every time the position is changed. Due to this, urine through the drainage catheter is not drained smoothly, or serious complications due to stagnation of urine may be caused. In addition, in severe cases, when the drainage catheter exploded and the procedure had to be repeated several times, there was a problem of increasing ineffective medical treatment.

To supplement this, a device for increasing the fixing force of the drainage catheter was developed in Korean Patent Registration No. 10-1822793, which is a prior art document. A seating groove (2) was formed in the fixing unit (1), and the drainage catheter (3) was inserted into the seating groove (2) to improve the fixation of the drainage catheter.

However, the conventional fixing device is limited to the fixing force by being opened on the top of the fixing unit, for example, when changing the position of the patient, there is a problem that the drainage catheter is released into the open portion.

Therefore, there is a need to develop a fixing device that is less affected by the patient's position change.

Also, the term “longitudinal direction” is an unshown y-axis direction perpendicular to the x-axis direction and the z-axis direction.

Hereinafter, with reference to Figures 2 and 3, look at the configuration and effect of the catheter fixing device according to the present invention.

The catheter fixing device according to the present invention includes a first body portion 100, a second body portion 200, a first groove portion 300, a second groove portion 400, a third groove portion 500, and a fixing portion 600 And an adhesive portion 700.

The first body portion 100 has a predetermined thickness in the vertical direction, and the lower surface is in contact with the patient's skin. In this case, in FIG. 2, as an example, the overall shape is a rectangular parallelepiped shape, but is not necessarily limited to this shape.

In this case, the first body portion 100 may be, for example, a cushioning feeling like a Mediform material, and a material that protects the patient's skin.

The second body portion 200 is positioned on the upper portion of the first body portion 100 and is coupled. It is preferable that the second body portion 200 also has a predetermined thickness in the vertical direction. In this case, in FIG. 2, as an example, the overall shape is a rectangular parallelepiped shape, but is not necessarily limited to this shape.

The first groove portion 300 is formed so that the upper portion is opened on the upper surface of the first body portion 100, it is preferable that the shape is formed to extend in the longitudinal direction.

At this time, it is preferable that the first groove portion 300 has a semi-circular cross section in the width direction as shown in FIG. 2. Due to this shape, since the first groove portion 300 and the second groove portion 400 to be described later are wrapped around the drainage catheter having a generally circular cross-section, the penetration of the drainage catheter is facilitated and the worker's working speed is improved. There is this.

The second groove 400 is formed so that the lower portion is opened from the lower surface of the second body portion 200, and is preferably formed to extend in the longitudinal direction.

At this time, it is preferable that the second groove 400 has a semi-circular cross section in the width direction as shown in FIG. 2. Due to this shape, as described above, there is an advantage in that the speed of penetration of the drainage catheter is improved.

At this time, it is preferable that the first groove part 300 and the second groove part 400 face each other, and the widths of the first groove part 300 and the second groove part 400 are preferably the same. Due to this, since the structure surrounding the entire outer surface of the drainage catheter is formed, the possibility of departure is low, so the probability of occurrence of the problem of re-treatment is lowered.

The third groove part 500 is formed to extend from the second groove part 400. Therefore, the second groove part 400 and the third groove part 500 are connected to form one groove when viewed from the outside.

The third groove portion 500 is preferably a cross-section in the width direction and a shape extending in the longitudinal direction.

At this time, the width of the third groove portion 500 is preferably shorter than the width of the lower end portion of the second groove portion 400. Due to this, one groove formed by the second groove part 400 and the third groove part 500 based on the second main body part 200 becomes narrower and narrower as it goes upward, and the second groove part 400 and At the point where the third groove 500 is connected, a shape is formed that extends in a vertical direction at regular intervals.

After the operator penetrates the drainage catheter between the first groove portion 300 and the second groove portion 400, the lifter is lifted in the vertical direction to place the drainage catheter between the third groove portion 500. Since the cross sections of the first groove part 300 and the second groove part 400 are semicircular, it is easy to penetrate the drainage catheter, but when the drainage catheter is positioned between the third groove parts 500, the movement in the width direction is limited and the fixing force This has the advantage of being increased.

The fixing part 600 is coupled to the inner surface of the third groove part 500. In more detail, it is coupled to the inner surface of the second body portion 200 formed by the third groove portion 500.

In addition, the fixing part 600 is provided in a pair. For convenience of description, the pair of fixing parts 600 are referred to as the first fixing part 610 and the second fixing part 620 based on FIGS. 2 and 3, respectively.

The first fixing part 610 and the second fixing part 620 are formed to extend in the longitudinal direction, and are respectively coupled to the inner surfaces of the third groove parts 500 facing in the width direction. For this reason, the pair of fixing parts 600 are formed to face each other in the width direction, and are formed to be spaced apart at predetermined intervals in the width direction.

At this time, the material of the pair of fixing parts 600 is preferably silicon. In the case of silicone material, it has flexibility and elasticity, and has a constant friction. The drainage catheter inserted into the third groove portion 500 is fixed by a pair of fixing portions 600. At this time, due to the fixing portion 600 made of silicone, it is easy to insert, and there is an advantage in that the fixing force is increased due to a predetermined frictional force after insertion.

The adhesive portion 700 is a layer positioned between the first body portion 100 and the second body portion 200. It is preferable that it has a predetermined thickness and is formed to extend in the longitudinal direction, and corresponding to the shapes of the first groove part 300 and the second groove part 400 in portions that come into contact with the first groove part 300 and the second groove part 400. Is open.

The upper surface of the adhesive portion 700 is combined with the lower surface of the second body portion 200, and the lower surface of the adhesive portion 700 is combined with the upper surface of the first body portion 100. The adhesive portion 700 serves to increase the adhesive force between the first body portion 100 and the second body portion 200, and the bonding force with the second body portion 200 due to the material characteristics of the first body portion 100 having a cushion feeling. Since it is weak, it serves to supplement it.

Due to the configuration of the drainage catheter fixing device as described above, the fixing force of the drainage catheter is increased compared to the conventional fixing device. Due to this, the drainage catheter is less affected by the position change of the patient, so that complications such as infection caused by folding of the drainage catheter according to the change of the position of the patient can be prevented.
