Specific implementation

[0019] For example, Figures 1 to 4As shown, the utility model relates to a kind of retention protection application for hemodialysis, including the fixed bottom piece 1 made of latex material, fixed bottom piece 1 is made of outer edge 101 and the hollow area 102 in central region, hollow area 102 inside is used to accommodate dialysis catheter, outer edge 101 surface is adhered with fixed layer 2, outer edge 101 surface one side is provided with crimping piece 6, outer edge 101 both sides are provided with fixed band 7, two fixed band 7 end portion is movably fixed, crimping piece 6 and fixed layer 2 and the end portion of two fixed band 7 are all fixed by magic tape, crimping piece 6 includes frame part 601 and protruding part 602, protruding part 602 is equipped with breathable gauze layer, breathable gauze layer plays the role of auxiliary ventilation, outer edge 101 edge is adhered with several strip-shaped positioning adhesive tape 9, positioning adhesive tape 9 plays the role of auxiliary positioning, reduce the possibility of fixed band 7 movement deviation, specific use can also not use positioning adhesive tape 9 to be fixed.

[0020] Working principle, when using, fixed bottom piece 1 is placed in dialysis catheter position, then fixed band 7 is passed around the neck of patient, and is fastened and fixed using magic tape, finally according to demand, the positioning adhesive tape 9 of adaptive quantity is used, i.e. can realize position fixing, thereby greatly reduce the amount of adhesive tape, improve comfort.

[0021] In the embodiment of the utility model, in order to fix the position of dialysis catheter, hollow area 102 is equipped with air bag layer 3 for pressing dialysis catheter, air bag layer 3 is communicated with multiple inflatable layers 4, air bag layer 3 one side is connected with the inner wall of outer edge 101 and has restraint strip 8, air bag layer 3 one side and outer edge 101 have gap, gap is mainly used for dialysis operation, inflatable layer 4 is equidistantly distributed at the outer edge of outer edge 101, notch is set on fixed layer 2 for inflatable layer 4 to pass through, thereby when crimping piece 6 is movably fixed with fixed bottom piece 1, the gas inside inflatable layer 4 can be extruded, inflatable layer 4 is provided with recovery structure 5 inside, recovery structure 5 includes sheet 501, the outer periphery of sheet 501 is same as the inner wall size of inflatable layer 4 and is adhered and fixed, sheet 501 one side is provided with elastic member 502 between outer edge 101 surface, and elastic member 502 is latex soft column or spring, and elastic member 502 only needs to have the effect of resilience.

[0022] Working principle, move crimping piece 6, make it adhere with fixed layer 2 through magic tape, realize position fixation with fixed bottom piece 1, sheet 501 will be extruded, sheet 501 drops, extrude internal gas to inflate air bag layer 3, realize the inflation of air bag layer 3, make air bag layer 3 periphery and skin adhere to constrain protection dialysis catheter, when dialysis is needed, crimping piece 6 is separated from fixed bottom piece 1, at this time, elastic member 502 makes the movement of recovery, and inflatable layer 4 returns gas, cancels the constraint state, and then dialysis operation can be carried out through the gap of air bag layer 3 one side.
