This modification can increase the holding strength of the catheter fixing device on the skin of the patient by providing the adhesive substrate 12 with a large area.

Another preferred embodiment according to the present invention will be described in detail below with reference to fig. 6 and 7, wherein fig. 6 shows a catheter fixing device according to another preferred embodiment of the present invention; and figure 7 shows a view of the catheter fixing device of figure 6 in use.

As shown in the drawings, the catheter fixing device 1 'generally includes a positioning body 11', the positioning body 11 'includes a base 112 and two band portions 113 extending from the base 112, the two band portions 113 are configured to be capable of being disposed around a portion of the catheter 10, preferably, as shown in the drawings, the two band portions 113 of the positioning body 11' are provided with hook and loop type magic tapes (not visible in fig. 6 and 7) as previously described, the two band portions 113 of the positioning body 11 'are fixedly connected to each other by engaging the loops with the hooks, thereby causing the positioning body 11' to be disposed around a portion of the catheter 10 as shown in fig. 7. Similarly, any other suitable fixing means may be used instead of the velcro tape.

Also, the catheter fixing device 1 ' further comprises a retaining means, which in this embodiment comprises a plurality of teeth 14, which teeth 14 are evenly distributed on one side of the positioning body 11 ', as shown, in particular on the inner surfaces of the base 112 and the two band portions 113, such that the plurality of teeth 14 can abut the catheter 10 to provide a gripping force to the catheter 10 when the positioning body 11 ' is arranged around a portion of the catheter 10. Advantageously, the size of the gap between the plurality of teeth 14 can be adjusted by adjusting the engagement position of the two band portions 113, so that it is possible to provide an appropriate gripping force for catheters 10 of different shapes and thicknesses. The catheter fixing device 1' with the configuration is easy to operate, can be reused and has high cost efficiency.

Preferably, the plurality of teeth 14 are made of an elastically deformable material, more preferably rubber, thereby further improving the dimensional adaptability to the catheter 10 and the flexible grip of the catheter 10.

Preferably, as best shown in fig. 6, the plurality of teeth 14 are configured to taper distally from the positioning body 11', which further facilitates deformation of the teeth to improve dimensional adaptability to the catheter 10 and flexible grip of the catheter 10. And preferably an arcuate recess 141 is provided at the distal end of the tooth 14, such arcuate recess 141 facilitating better accommodation of the arcuate outer wall of the catheter 10 when the tooth 14 abuts the catheter 10.

Also, as shown in fig. 6, the positioning body 11 'comprises a width direction a, and when the positioning body 11' is arranged around a portion of the catheter 10, the positioning body 11 'surrounds a radial direction B forming a substantially circular shape and perpendicular to the width direction a, i.e. a direction radiating from the center of the circle formed by the positioning body 11' towards the periphery of the circle as schematically shown in the figure (i.e. comprising a plurality of radial directions B, e.g. shown in fig. 6, which lie in the same circular plane). Preferably, each tooth 14 is configured to be inclined at substantially the same angle toward the inside in the width direction a of the positioning body 11', which also contributes to improving the dimensional adaptability of the tooth 14 to the catheter 10 and the flexible grip of the catheter 10. Furthermore, alternatively, as shown in fig. 7, each tooth 14 may also be configured to be inclined toward the same circumferential direction (i.e., all clockwise inclined, or all counterclockwise inclined, all counterclockwise inclined in fig. 7) by substantially the same angle with respect to the radial direction B of the positioning body 11', which can also bring about the same effect of improving the dimensional adaptability of the teeth 14 to the catheter 10 and the flexible grip of the catheter 10.

Further, preferably, as shown in fig. 6, the plurality of teeth 14 are arranged in two rows, and the teeth 14 in different two rows are staggered with each other. This can provide a more uniform, reliable grip for the catheter 10 and reduce excessive force on certain parts of the catheter 10. Alternatively, the plurality of teeth 14 may be arranged in a single row, or three and more rows, and it is feasible that the teeth 14 in different rows are staggered or aligned with each other, or have different sizes, shapes, and/or inclination directions and angles, etc., to each other, which may be adjusted as the case may be.

Further, by fixing the positioning body 11 'together with the catheter 10 as described above, the catheter 10 can be prevented from being displaced with respect to the positioning body 11'. Also, as shown in fig. 7, the outer side surface of the base portion 112 of the positioning body 11 'includes an adhesive region (not visible in the drawing) to be fixed to a predetermined position such as a patient's body, thereby reliably positioning the catheter 10. Alternatively, an adhesive substrate 12 as shown in fig. 5 may be provided, and the positioning body 11 ' may be adhesively fixed to the adhesive substrate 12, or the positioning body 11 ' may be fixed in position by providing the base 112 of the positioning body 11 ' with the two insertion openings 122 provided in the adhesive substrate 12 as described above.
