Description

Fistula anti-drop device capable of eliminating friction drop Technical Field The utility model relates to a medical appliance, in particular to a fistulization pipe anti-drop device for eliminating friction drop. Background Fistulae are a type of tubing used for medical purposes, which surgically connects a site inside the body with the outside of the body, and are commonly used to drain waste or body fluids from the body, and whose primary function is to assist those who are unable to drain waste by normal routes, such as by disease, surgery or other reasons, to maintain normal physiological function. In the use process of the fistulization pipe, a very troublesome problem is often encountered, because the extending end of the fistulization pipe needs to be directly contacted with the skin of a patient, in daily activities, friction is generated between the fistulization pipe and clothes, bedsheets or bedclothes of the patient, the friction is particularly remarkable when the patient moves or changes postures, particularly in the processes of dressing, turning over, walking or sleeping, when the friction force is overlarge, the fistulization pipe inserted into the body is easily pulled, so that the fistulization pipe is partially or completely detached, the normal function of the fistulization pipe is directly influenced, additional secondary injury is brought to the patient, and the patient is possibly forced to receive emergency treatment or medical operation for many times by losing the original fixed fistulization pipe, so that the medical burden of the patient is further increased. At present, many fistulae are tightly attached to the skin of a patient by adopting a sterile patch, although the method can reduce the friction between the fistulae and external articles such as clothes, bed sheets and the like to a certain extent, thereby reducing unnecessary external force action, in practical application, a plurality of problems still exist, especially in terms of fixing effect and stability, as the fistulae are cylindrical, the attaching effect of the sterile patch when being in contact with a tube body is not ideal due to the shape, the sterile patch is usually based on a planar design, the contact with the fistulae is mainly 'point-to-point' or 'line-to-line' contact when being applied, the cylindrical surface cannot be fully attached, the fixing effect is greatly discounted due to the contact mode, stable all-round support cannot be formed, the defect in the design is particularly obvious in daily activities of the patient, when the patient performs the action of turning over, walking or other possibly causing the displacement of the fistulae, the extension part of the fistulae often bears the pulling force from the body or the external clothing, if the fixing is not ideal, the sterile patch is in contact with the skin, the sliding effect can not be caused, the poor skin is prevented from being removed, the bad, the skin is prevented from being easily pulled down, and the bad skin is prevented from being caused by the sliding, the bad skin is caused, the bad is caused, and the bad skin is prevented from being easily pulled, and the bad is caused.
