Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a catheter fixing device for fixing a catheter indwelled in the body and preventing the catheter from coming out of the indwelling site.

<Prior Art> When a catheter is placed in a patient's body, such as a vein, it is necessary to secure the catheter so that it does not fall out. The fixing position of a catheter varies from patient to patient, so conventional methods of fixing an indwelling catheter include attaching the tube directly to the skin with a bandage, etc., so that the catheter can be fixed at any position. For example, using a wing-shaped fixture with a tube insertion groove and a hole for sewing, as shown in Figure 5, insert the tube into the groove, turn the tube downward, and sew the fixture to the skin at the hole. In addition, using a fixing device having a tube insertion groove and an annular groove on the circumferential wall of the tube as shown in Fig. 6, insert the tube into the groove, and sew the fixing device to the skin at the annular groove with the tube facing downward. I was doing a lot of things.

However, although the method of pasting with a bandage or the like is simple, the tube is likely to come off, and the fixing devices shown in FIGS. 5 and 6 pose a problem in that there is a risk that the tube may come off or shift back and forth.

<Problem that the invention aims to solve> This invention was made in view of the above problems.
To provide a catheter fixing device which can be smoothly moved to any position of the fixing device, can prevent the tube from shifting or coming off, and can be securely fixed to the skin.

<Means for Solving the Problems> In order to solve the above problems, the present invention consists of a pair of wings having a hinge, and the wings are coupled around the tube of a catheter inserted into the hollow part of the hinge. A catheter fixing device characterized in that the center of the hollow portion of the hinge is eccentric with respect to the center of the hinge so that it deviates when the wings are opened and substantially coincides with the center when the wings are closed. is adopted.

<Function> According to the above configuration, when the tube of the catheter inserted into the catheter fixing device is opened, the centers of the left and right hollow portions will be shifted the most when the pair of wings are open, so It is fixed (see Figure 3 A), and when the wings are closed, that is, when the pair of wings are rotated around the hinge and aligned, the hollows of the left and right hollow parts will match, so it can be released from the fixing device. (See Figure 3B). Therefore, when the tube is fixed to the fixture,
The tube will not come off from the fixture,
Also, when the tube is released from the fixture,
The fixture can be moved to any position on the tube.

<Example> Next, an example of the present invention will be described based on the drawings.

Fig. 1 is a perspective view of a catheter fixing device according to an embodiment of the present invention, Fig. 2 is a plan view of the right wing in Fig. 1, and Fig. 3 is a diagram explaining the operation of the catheter fixing device of the present invention. FIG. 4 is a diagram showing another embodiment of the hinge portion of the present invention.

The catheter fixing device 1 of the present invention is a fixing device that is used by being fixed to the skin of a patient in order to prevent a catheter placed in the body from falling off. , 3, and the wings 2, 2 are connected around the tube of the catheter which is inserted into the hollow part 4 of the hinges 3, 3. The center of the hollow portion 5 is eccentric with respect to the center of the hinges 3, 3.

The wing 2 is a part that fixes the catheter to the patient's skin, and is generally made of plastic, etc., although it is not particularly limited, and the wing 2 that fixes the catheter is preferably attached to the skin at the end using sutures or the like. A suture hole 5 for sewing is formed.

The hinges 3, 3 are parts that connect the wings 2, 2,
It is formed into a substantially cylindrical shape, and the hinges 3, 3 of the left and right wings 2, 2 are connected so that their convex portions and concave portions are engaged with each other. The hollow portion 4 of the hinge 3 is eccentrically formed so that its center is offset from the center of the hinge 3 when the wings 2, 2 are opened, and substantially coincides with the center when the wings 2, 2 are closed.

To explain clearly (see Figure 3), when the wings 2, 2 are fully opened as shown in Figure 3A,
The hollow parts 4, 4 have the largest deviation, and as the wings 2, 2 are closed (Fig. 3B), the deviation of the hollow parts 4, 4 becomes smaller, and when the wings 2, 2 are completely closed, the hollow parts 4 and 4 substantially match. The shape of the hollow part 4 is not particularly limited, but in addition to circular shape,
Various shapes such as an ellipse as shown in FIG. 4 can be adopted.
