Between connect into an entirety, gap can be formed between negative pressure box, the presence in gap can make air circulation at patient skin, no
Easily grow bacterium；
After negative pressure box is attached on patient skin, the transmission fluid in negative pressure box is extracted, between negative pressure box lower face and patient skin
It is formed negative pressure space, to which negative pressure box to be adsorbed on patient skin, can be very good to connect in negative pressure box and patient skin
Together, dialysis tubing is fixed with clamping piece, firmly turns bolt, the space in B seal chambers becomes smaller, and resin particle will
Cotton is squeezed, cotton can wrap dialysis tubing, and resin particle can be very good to fix dialysis tubing, and dialysis tubing is made not allow fallibility
Position, in this way, effect through the invention, can be very good dialysis tubing and patient skin being fixed together, consolidate to dialysis tubing
It is fixed better；
When fixing dialysis tubing with clamping piece, the reset condition of dialysis tubing is kept, bolt is turned, these tiny resin particle meetings
Position and the size for adapting to dialysis tubing to the greatest extent, dialysis tubing are wrapped up well, and dialysis tubing is fixed, so no matter
Dialysis tubing is in which kind of angle or position, can not become in holding dialysis tubing state, be carried out very to dialysis tubing
Good fixation；
Resin particle is harder, and many resin particle stack ups are equivalent to an entirety, and resin particle will not be easily wrong
Position, so carrying out extruding fixation to dialysis tubing with resin particle, exactly holds together dialysis tubing and resin particle, to saturating
The fixed effect for analysing pipe is more preferable.
2, gasket can make the possibility of the negative pressure space formed between negative pressure box and patient skin reduction gas leakage, gasket
Gasket can also be made to stick together with patient skin using silica gel material, help fixed negative pressure box.
3, deformation can be preferably carried out as the elastic membrane of natural rubber material, and elastic membrane can be very thin, will not made
The skin of patient does not feel well.
