The present embodiment is a method embodiment corresponding to embodiment 3, and repeated details are not repeated.

The embodiment provides a pipeline fixing method, which at least comprises the following steps:

a skin far region 110 is arranged, and skin near regions 120 are arranged on two sides of the skin far region 110;

the distal skin region 110 extends along a side where the proximal skin region 120 is not disposed to form a separate tubing connection region;

the near skin region 120 enables sustained administration.

The fixing method of the present embodiment further includes:

A preferred embodiment is provided wherein the fixation device further comprises a variable attachment lumen, at least a portion of the sidewall of which is surrounded by the distal skin region 110. The variable connecting chamber is constructed in a structure capable of changing at least the chamber volume thereof, and a typical example is a spherical or olive-shaped chamber structure constructed of an elastic material. The variable connecting cavity is provided with at least two opening channels communicated with the internal cavity, and the two opening channels are respectively coupled with the upstream and downstream ports of the pipeline to form a circulating pipeline path. When the inside of the variable connecting cavity is in an empty state, namely the variable connecting cavity is in natural elasticity, the volume of the variable connecting cavity is called a first volume at the moment; when the variable connection chamber is filled with a filler conforming to the volume of the first volume and continues to fill so that the variable connection chamber itself deforms to expand to a volume greater than the first volume, the parameter greater than the first volume is referred to as the second volume. It will be appreciated that when the variable connection chamber is in the second volume, its external volume increases, i.e. it expands. In this case, the two open channels of the variable connection chamber are divided into an upstream channel and a downstream channel according to the position of the pipe in which they are coupled in the flow line, wherein the downstream channel is configured to be openable at least in the event of a change of the variable connection chamber from the first volume to the second volume by the filling being fed in, so that the filling can be discharged by the downstream channel to bring the variable connection chamber back to the first volume from the second volume deformation. Depending on the context of use of the device, the filler is typically a substance having fluid properties, such as urine from the patient, nutrient solution to be fed to the patient, etc. The above-described selective opening of the downstream channel under certain conditions may be achieved based on a correlation between a varying pressure of the variable connection chamber at the interface of the downstream channel and an opening pressure selected when the downstream channel is constructed. A typical example is that the downstream channel is configured as a valve, e.g. a duckbill valve, that is automatically openable based on a certain pressure, and that the opening pressure of the downstream channel is configured to be at least greater than the pressure generated at the interface of the downstream channel when the first volume of the variable connection chamber is filled. Further, the downstream channel may also be configured to be able to close slowly, e.g. by selecting some valve structures with pre-stress, so that the variable connection chamber can slowly decrease from the second volume to the first volume after the downstream channel is opened. When the variable connection chamber is at the second volume, the first pressure at which the variable connection chamber is in contact with the skin increases, thereby causing the near-skin region 120, which is separated on either side of the variable connection chamber, to relieve its own second pressure on the patient's skin due to the variable connection chamber being recessed into the patient's skin to a greater extent.

The pipeline fixing device provided by the arrangement realizes that the part of the pipeline fixing device, which is contacted with the skin of the patient, is periodically subjected to pressure change massage by utilizing certain events which are periodically generated in the life of the patient and are utilized to the drainage tube, so that the pressure sore of the patient can be prevented and treated under the condition that any external power source is not introduced. For example, in the case of a medical professional injecting a nutritional liquid into a patient's nasal feeding tube, the variable connection chamber is filled with the filling material and the volume is increased, and the provision of the downstream channel ensures that the variable connection chamber can expand to a significant change in pressure against the patient's skin, which is indicative of the variable connection chamber transitioning from an original only slight contact to the patient's skin to compression against the patient's skin, in which case the pressure of the skin proximal regions 120 on either side of the variable connection chamber is relatively reduced due to the shift in the center of gravity of the overall pressure of the fastening device, the patient's skin is in a concave middle, a U-shaped state with the ends deflected, and thus the patient's skin compressed by the skin proximal regions 120 over a prolonged period of time can be alleviated by the reduced second pressure. Further, since the flow rate of the filler entering the variable connecting chamber is different and the flow rate is different, the downstream channel is arranged at the same time, so that the volume of the variable connecting chamber can be slowly reduced, and the pressure of the skin of the patient on the middle part contacted with the variable connecting chamber and the two side parts contacted with the skin near area 120 is changed at any time, thereby forming the massage effect. The scheme does not introduce any external power source, but only relies on the filler passing through the pipeline connected to the patient as power, and the filler is used as a substance which is necessary to participate in the flow for recycling. It should be noted that, the additional power equipment, such as a motor and an air charging device, which are provided for generating the variable pressure at the pipeline fixing device, further aggravate the pressure of the pipeline fixing device at the skin of the patient, but the pressure of the pipeline fixing device may not be reimbursed.
