Definitions
- the object of the present invention is to provide a skin stretcher that can simultaneously use negative pressure suction.
- a skin stretcher that can use negative pressure suction at the same time including:
- Fig. 3 is a schematic diagram of the skin stretcher that can simultaneously use negative pressure suction according to the present invention.
- the skin stretcher that can use negative pressure suction at the same time also includes: a winding mechanism, the winding mechanism includes: a winding shaft outer cylinder 51 arranged on the top of the bottom dressing 2, a lower end The bobbin 52 inside the bobbin outer cylinder 51 and the knob 53 matched with the upper end of the bobbin 52, wherein the bobbin outer cylinder 51 is provided with an outlet hole, and the other end of the tension line 3 is connected to the wire through the outlet hole.
- the winding shaft 52 is connected, and by rotating the winding shaft 52, one end of the tension wire 3 is moved toward the winding shaft 52 or one end of the tension wire 3 is allowed to move away from the winding shaft 52 .
- the tension wire 3 is tightened by rotating the winding shaft 52 , and the tension wire 3 is loosened by reversely rotating the winding shaft 52 . This results in stretching and adjustment of the skin.

Abstract
Dispositif d'étirement cutané pouvant simultanément utiliser une aspiration à pression négative, comprenant : un tube flexible perforé (1), qui est agencé le long d'une première direction ; un pansement inférieur (2), dont au moins une partie vient en contact avec le tube flexible perforé (1) ; un fil de tension (3), qui est agencé le long d'une seconde direction croisant la première direction, une extrémité du fil de tension (3) étant reliée à une plaque de traction (4), et la plaque de traction (4) étant reliée à la peau ; et un mécanisme d'enroulement, qui comprend : un cylindre externe d'arbre d'enroulement (51) disposé au-dessus du pansement inférieur (2), un arbre d'enroulement (52) dont l'extrémité inférieure est disposée à l'intérieur du cylindre externe d'arbre d'enroulement (51), et un bouton (53) qui est associé à l'extrémité supérieure de l'arbre d'enroulement (52), un trou de sortie de fil étant prévu sur un cylindre externe de l'arbre d'enroulement (52), l'autre extrémité du fil de tension (3) étant relié à l'arbre d'enroulement (52) par l'intermédiaire du trou de sortie de fil, et une extrémité du fil de tension (3) étant amenée à se déplacer vers l'arbre d'enroulement (52) ou une extrémité du fil de tension (3) étant amenée à s'éloigner de l'arbre d'enroulement (52) au moyen de la rotation de l'arbre d'enroulement (52). Une traction cutanée et une aspiration à pression négative peuvent être simultanément réalisées, et la technologie d'aspiration à pression négative peut être utilisée pour éviter une infection lors d'un étirement cutané.
