Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a dressing patch for fixing an intra-aortic balloon counterpulsation catheter. Background Art

[0002] Intra-aortic balloon pump (IABP) is one of the most widely used mechanical circulatory assist devices, which is convenient to use, has relatively few complications, and has important therapeutic significance for critically ill cardiovascular patients with impaired heart function and decreased cardiac output.

[0003] IABP mainly consists of a counterpulsation balloon, a catheter and an external control device. The counterpulsation balloon is placed in the descending aorta and is periodically inflated and deflated according to the cardiac cycle.

[0004] In clinical use of intra-aortic balloon pump, most of them use sterile gauze or sterile dressings to cover the puncture site and exposed tubes for fixation. Due to the length or material, it is impossible to directly observe whether the exposed catheter is bent or dislocated. Since the IABP is usually left in the body for 3-7 days or longer, it is particularly important to properly fix the tube and avoid infection. Utility Model Content

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0021] like Figure 1-4 As shown, a dressing patch for fixing an intra-aortic balloon counterpulsation catheter according to a preferred embodiment of the utility model comprises a first dressing portion 1 for separating the skin and the balloon counterpulsation catheter and a second dressing portion 2 for covering the puncture port, a plurality of fixing components 3 arranged at intervals along the length direction of the first dressing portion 1 are provided on the top of the first dressing portion 1, the fixing components 3 comprise a fixing buckle 31 and a fixing belt 32, the fixing buckle 31 is fixed on one side of the first dressing portion 1, a first end of the fixing belt 32 is fixed on the other side of the first dressing portion 1, a first Velcro 321 is provided on the top surface of the first end of the fixing belt 32, a second Velcro 322 is provided on the top surface of the second end of the fixing belt 32, the second end of the fixing belt 32 passes through the fixing buckle 31 and then wraps around the top of the first end of the fixing belt 32, the first Velcro 321 is bonded to the second Velcro 322, and the second dressing portion 2 is separated from the first dressing portion 1.

[0022] The working principle of this embodiment is as follows: when in use, first cover and fix the second dressing part 2 on the puncture hole, at which time the exposed part of the balloon counterpulsation catheter extends from one side of the second dressing, then fix the first dressing part 1 on the skin near the puncture hole, and separate the fixing belt 32 from the fixing buckle 31, then place the exposed part of the balloon counterpulsation catheter on the first dressing part 1, and adjust the position of the balloon counterpulsation catheter so that it is located between the fixing buckle 31 and the first end of the fixing belt 32, then pass the second end of the fixing belt 32 around the top of the exposed part of the balloon counterpulsation catheter, pass through the fixing buckle 31, and then go around to the top of the first end of the fixing belt 32, finally bond the first Velcro 321 and the second Velcro 322, at which time the fixing belt 32 presses the exposed part of the balloon counterpulsation catheter to achieve fixation of the balloon counterpulsation catheter. The exposed part of the tube is fixed; the first dressing part 1 and the second dressing part 2 of the present embodiment are separated from each other for easy use. The first dressing part 1 and the second dressing part 2 can be replaced separately without replacing the whole part, which reduces the tearing area, helps to protect the skin and is easy to replace; the exposed part of the balloon counterpulsation catheter is fixed by multiple fixing components 3, and the condition of the exposed part of the balloon counterpulsation catheter can be observed intuitively. The first Velcro 321 and the second Velcro 322 are repeatedly bonded to facilitate adjustment of the length of the exposed part of the balloon counterpulsation catheter and then fixation again; the first dressing part 1 serves to separate the skin and the exposed part of the balloon counterpulsation catheter, and to protect the skin, and can prevent the skin from being directly squeezed by the exposed part of the balloon counterpulsation catheter (the exposed part of the balloon counterpulsation catheter is provided with hard plastic, which will squeeze the skin after fixation).

[0023] Exemplarily, the first dressing portion 1 is provided with a scale 4 arranged along its length direction, and medical personnel can adjust the exposed length of the balloon counterpulsation catheter according to the scale 4, which is more accurate and reliable.

[0024] Exemplarily, one end of the first dressing portion 1 is provided with a tear line 5 arranged along its width direction. A plurality of tear lines 5 are provided, and the plurality of tear lines 5 are arranged at intervals along the length direction of the first dressing portion 1. The first dressing portion 1 is torn along the tear line 5 to adjust the length of the first dressing portion 1. In the present embodiment, the length of the first dressing portion 1 is 30 cm and the width is 10 cm. Three tear lines 5 are provided, and the distances from one end of the first dressing to the three tear lines 5 are 24 cm, 26 cm and 28 cm, respectively, to meet the use requirements of different exposed lengths of the balloon counterpulsation catheter.

[0025] Exemplarily, the first dressing part 1 includes a release paper layer 11, a silicone layer 12 and a polyurethane foam layer 13 which are arranged in sequence from bottom to top. The fixing component 3 is arranged on the polyurethane foam layer 13. The polyurethane foam layer 13 has good pressure resistance. The material of silicone is mild, low-sensitivity, and can be repeatedly pasted. The release paper layer 11 has anti-stickiness. Glue is applied on the bottom surface of the silicone layer 12 in advance, and then the release paper layer 11 is attached to the bottom surface of the silicone layer 12. When in use, the release paper layer 11 can be directly torn off to stick the silicone layer 12 to the skin, which is easy to use.

[0026] Exemplarily, the second dressing part 2 includes an antibacterial layer 21, a hygroscopic layer 22, a self-adhesive layer 23 and an isolation layer 24, which are arranged in sequence from bottom to top. In this embodiment, the antibacterial layer 21 is a nano-silver coating, the hygroscopic layer 22 is a cotton non-woven fabric, and the self-adhesive layer 23 is a medical tape. The four sides of the self-adhesive layer 23 extend beyond the four sides of the antibacterial layer 21 and the hygroscopic layer 22, respectively, to facilitate sticking the self-adhesive layer 23 to the skin to achieve fixation of the second dressing part 2. In this embodiment, the antibacterial layer 21 and the hygroscopic layer 22 have the same size, both are rectangles of 6 cm*4 cm, and the self-adhesive layer 23 and the isolation layer 24 have the same size, both are rectangles of 10 cm*8 cm.

[0027] Illustratively, a trumpet-shaped avoidance opening 25 is provided on one side of the self-adhesive layer 23, and the exposed portion of the balloon counterpulsation catheter is provided with a protective cover that can be stretched and adjusted in length. When the second dressing portion 2 covers the puncture port, one end of the protective cover is located in the avoidance opening 25 to prevent the end of the protective cover from being adhered to the self-adhesive layer 23, thereby preventing the protective cover from being damaged during subsequent tearing off and affecting the sterility of the protective cover.

[0028] Exemplarily, the four corners of the second dressing portion 2 are provided with rounded corners, which are not easy to form curling edges and the fit is more secure.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
