[0030] Refer to Figures 1 - 5 A temporary dialysis catheter fixator provided by the present utility model includes: a first rigid piece 1, a second rigid piece 2, a baseband 9, a first adhesive patch 13, and a second adhesive patch 14.
[0031] Among them, the first rigid piece 1 and the second rigid piece 2 are symmetrically distributed at intervals, and the catheter to be fixed is located in the gap between the first rigid piece 1 and the second rigid piece 2, thereby restricting the catheter. The bottom of the first rigid piece 1 and the bottom of the second rigid piece 2 are fixedly connected to a baseband 9 together, so that the relative positions of the first rigid piece 1 and the second rigid piece 2 are basically unchanged. A first horizontal notch 4 is provided on the side of the first rigid piece 1, and a second horizontal notch 3 is provided on the side of the second rigid piece 2. Generally, a horizontal protrusion is provided at the joint of the catheter to be fixed. The first horizontal notch 4, the second horizontal notch 3 correspond to the horizontal protrusion provided at the joint of the catheter to be fixed. After the protrusion is stuck between the first horizontal notch 4 and the second horizontal notch 3, the entire catheter to be fixed is not likely to slide along its length direction anymore, so that the catheter can be fixed better.
[0032] The first adhesive patch 13 is folded in an "S" shape, and it includes a first horizontal part 131, a second horizontal part 132, and a fitting part 134 which are integrally arranged; among them, the bottom of the first horizontal part 131 is an adhesive surface for fitting with the human skin, the top of the second horizontal part 132 is an adhesive surface for fitting with the bottom of the first rigid piece 1 and the bottom of the baseband 9, and the bottom of the fitting part 134 is an adhesive surface corresponding to the second rigid piece 2 and fitting with the catheter to be fixed and the second rigid piece 2. The second adhesive patch 14 has the same structure as the first adhesive patch 13 and is symmetrically distributed about the center.
[0033] In this solution, only the first adhesive patch 13 and the second adhesive patch 14 are needed to complete the fitting with the patient's skin, the fitting with the first rigid piece 1 and the second rigid piece 2, and the fitting with the catheter to be fixed, thus saving adhesive tape relatively; moreover, as the structure of the first adhesive patch 13 shows, when it is unfolded, only one surface is the bonding surface. Compared with using double-sided adhesive tape, the adhesive tape used has a lower cost and is easier to manufacture.
[0034] In one embodiment, the fitting portion 134 is in a horizontally placed L shape. When in use, the first adhesive patch 13 and the second adhesive patch 14 can complement each other to fix the catheter to be fixed together with the first rigid piece 1 and the second rigid piece 2.
[0035] Among them, the first rigid piece 1 and the second rigid piece 2 can be made of cardboard or lightweight plastic material.
[0036] In one embodiment, a plurality of first horizontal notches 4 and second horizontal notches 3 are provided, and the number of the first horizontal notches 4 is the same as that of the second horizontal notches 3.
[0037] Each group of the first horizontal notch 4 and the second horizontal notch 3 corresponds to a horizontal protrusion provided at the joint of the catheter to be fixed, so that the temporary dialysis catheter fixator can be used in matching with various models of catheters to be fixed.
[0038] In one embodiment, a first notch 5 is locally provided at the bottom of the first rigid piece 1, and a first protrusion 6 is formed at the bottom of the first rigid piece 1 (that is, the first protrusion 6 is formed at the position where the first notch 5 is not opened at the bottom of the first rigid piece 1). A second hole portion 11 corresponding to the first protrusion 6 is provided on the base band 9, so that the base band 9 and the first rigid piece 1 are not prone to lateral sliding.
[0039] A second notch 7 is locally provided at the bottom of the second rigid piece 2, and a second protrusion 8 is formed at the bottom of the second rigid piece 2 (that is, the second protrusion 8 is formed at the position where the second notch 7 is not opened at the bottom of the second rigid piece 2). A first hole portion 10 corresponding to the second protrusion 8 is provided on the base band 9, so that the base band 9 and the second rigid piece 2 are not prone to lateral sliding.
[0040] In one embodiment, a third hole portion 133 corresponding to the first protrusion 6 is provided on the second horizontal portion 132 to increase the connection stability between the first protrusion 6 and the second horizontal portion 132 and make them not prone to lateral relative sliding.
[0041] In one embodiment, the base band 9 is made of elastic fabric, and an installation rope 12 is provided between the first rigid piece 1 and the second rigid piece 2. The distance between the first rigid piece 1 and the second rigid piece 2 can be adjusted within the maximum distance between the first rigid piece 1 and the second rigid piece 2 defined by the installation rope 12 to adapt to catheters of different thicknesses.
[0042] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
