Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a medical catheter that is easy to fix. Background Technology

[0002] In current clinical medical treatment, medical catheters, as conduits connecting the inside and outside of the human body, are widely used in the medical field, such as drainage tubes, infusion tubes, transfusion blood vessels, and indwelling urinary catheters. After successful placement, medical tape is often used to fix the catheter in place to prevent displacement.

[0003] The existing technology still has the following shortcomings:

[0004] Existing fixation straps are fixed to the skin through adhesive surfaces. However, since the position cannot be adjusted after application, it is necessary to repeatedly confirm the placement before application. Also, when removing them, the tight adhesion to the skin can easily cause damage to the skin's surface, resulting in poor practicality. Furthermore, they cannot absorb sweat from the patient's body. When sweat wets the adhesive surface wrapped around the catheter, the adhesiveness of the adhesive surface decreases sharply, and the comfort level is also low. Utility Model Content

[0005] This invention provides a medical catheter that is easy to fix, aiming to solve the problems of existing fixation straps, which are fixed to the skin by adhesive surfaces. However, after the straps are applied, the position cannot be adjusted, so the position needs to be repeatedly confirmed before application. Also, when removing the straps, the tight adhesion to the skin can easily cause damage to the skin surface, resulting in poor practicality. Furthermore, the straps cannot absorb sweat from the patient's body. When sweat wets the adhesive surface of the catheter, the adhesiveness of the adhesive surface decreases sharply, resulting in low comfort.

[0007] Preferably, each of the fixing components further includes a screw located at the middle of the upper end of the limiting frame; the extended end of the screw passes through the limiting frame and is connected to an arc-shaped clamping seat via a bearing; guide rods are fixedly connected to both sides of the upper end of the arc-shaped clamping seat, and the extended ends of the two guide rods pass through both sides of the limiting frame.

[0008] Preferably, both of the mounting components include fixing blocks that are fixedly connected to both sides of the base fabric. A fixing groove is provided on one side of the fixing block, and a connecting block is fixedly connected to the side of the elastic band near the fixing groove. The connecting block and the fixing groove are inserted into each other.

[0009] Preferably, both mounting components also include a through groove formed on the connecting block, and through holes are formed on both sides of the fixing block, with the two through holes respectively communicating with the fixing groove.

[0010] Preferably, each of the two mounting components further includes a support plate fixedly connected to the middle of the through slot, springs fixedly connected to both sides of the support plate, limit blocks fixedly connected to the extended ends of the two springs, and the two limit blocks respectively engaging with the two through holes.
