摘要：
A catheter securing device for securing a catheter on the body surface of a patient, comprising a securing body (2), a skin bonding layer (1), and at least one hoop strip (4). A rotary guiding mechanism is provided between a rotary ring (22) and a fixed ring (21). The rotary guiding mechanism comprises a sliding piece (23), the shape of said sliding piece (23) being adapted to that of the rotary ring (22) and said sliding piece (23) being fixedly connected to the rotary ring (22). Connecting columns (42) are provided on the sliding piece (23), the number of said connecting columns (42) being the same as that of the hoop strips (4) and said connecting columns (42) are connected one-to-one to the hoop strips (4). The sliding piece (23) is a circular whole, and is fixedly connected to the rotary ring (22). The number of the sliding piece (23) has no correspondence to that of the hoop strips (4). The strength among the rotary ring (22), the sliding piece (23), and the fixed ring (21) is increased, the rotary ring (22), the sliding piece (23), and the fixed ring (21) would not easily separate from each other and would not easily be separated under the effect of an external force； the catheter securing device has technical advantages of high strength and a long service life.L'invention concerne un dispositif de fixation de cathéter pour fixer un cathéter sur la surface corporelle d'un patient, comprenant un corps de fixation (2), une couche de liaison à la peau (1), et au moins une bande de frette (4).
