Definitions

  • the present invention relates to a device for maintaining negative pressure under the skin which is capable of maintaining the state of the negative pressure under the skin generated by lifting the skin and speeding up the metabolism of the cells under the skin to allow activation of the cells.
  • a gas-impermeable rigid housing is placed to cover the wound region of a patient and form a cavity between the housing and the skin, from within which oxygen is removed to produce a negative pressure by sealing the cavity and reducing the pressure of the cavity in an air-tight manner for the purpose of promoting healing of the wound region.

  • the upper portion 22A of the holding part 20A need not necessarily be flat as illustrated in Fig. 8 , but may be of a shape as part of a sphere such as a hemisphere, a shape which is obtained by intersecting an oval sphere with a plane perpendicular to the major axis thereof, or any other shape with the upper portion of the holding part protruding away from the lower portion.
  • the distance between the adhering surface and the skin can be larger to generate a larger restoring force.
  • the device 1A for maintaining negative pressure under the skin includes the holding part 20A having an upper portion, as an example, of a shape which is obtained by intersecting an oval sphere with a plane perpendicular to the major axis thereof as described above, rather than the planer shape. As shown in Fig. 9 , the device 1A for maintaining negative pressure under the skin includes the holding part 20A having an upper portion, as an example, of a shape which is obtained by intersecting an oval sphere with a plane perpendicular to the major axis thereof as described above, rather than the planer shape. As shown in Fig.
  • the device 1A for maintaining negative pressure under the skin includes the holding part 20A having an upper portion as an example of a shape which is obtained by intersecting an oval sphere with a plane perpendicular to the major axis thereof as described above, rather than the planer shape.
  • FIG. 9 shows the device 1A for maintaining negative pressure under the skin placed on the skin S, (b) shows the upper portion of the holding part 20A which is pushed down in order that the adhering surface of the plate 11 is attached to the skin S, and (c) shows the holding part 20A which is lifting up the skin S to a predetermined position by the restoring force caused by the elasticity thereof when releasing the force of pushing the upper portion of the holding part 20A after the skin S is attached to the adhering surface of the plate 11.
  • a sheet covering the adhering surface is first removed to expose the adhesive or the adhering surface of a double coated adhesive tape, and then the holding part 20A of the device 1A for maintaining negative pressure under the skin is placed on the skin S as illustrated in (a).
  • the adhering surface is urged against the skin S by pressing the upper portion of the holding part 20A of the device 1A for maintaining negative pressure under the skin with a finger or the like. Namely, since the device 1A for maintaining negative pressure under the skin has elasticity, the upper portion has to be pressed against the restoring force caused by the elasticity.
  • the adhering surface of the plate 11 can be attached to the skin S in this way.
  • the plate 11 attached to the skin S as shown in (c) can be removed from the skin S by pulling the plate 11, while twisting the holding part 20A, in order to detach the plate 11, which is fixed to the holding part 20A through the fixed part 12A, from the skin S.
  • the present embodiment has been explained with the holding part 20A and the plate 11 of the stuck part 10 of the same shapes as in the first embodiment, and explained with the upper portion of a different shape.
  • the holding part 20A and the plate 11 are not limited to those as illustrated in the drawings, but can be formed of various shapes such as has been described for the first embodiment.
  • Fig. 10 is a front view for showing the device for maintaining negative pressure under the skin of the third embodiment
  • Fig. 11 is a plan view for showing the device for maintaining negative pressure under the skin of Fig. 10
  • Fig. 12 is a bottom view for showing the device for maintaining negative pressure under the skin of Fig. 10 .
  • the device 1B for maintaining negative pressure under the skin of the present embodiment consists of a stuck part 10B to be stuck to the skin S, and a holding part 20B to be placed on the skin S such that the stuck part 10B is held in a predetermined position in the same manner as those of the first and second embodiments, but differs from the first and second embodiments in that the stuck part 10B comprises an adhering surface provided in the ceiling 25 which is the surface of the upper portion 22B of the holding part 20B located opposite the skin when the holding part 20B is placed on the skin S.
  • the stuck part 10B comprises an adhering surface provided in the ceiling 25 which is the surface of the upper portion 22B of the holding part 20B located opposite the skin when the holding part 20B is placed on the skin S.
  • it mainly features the configuration without the supportee part 12 and the fixed part 12A as used in the above embodiments.
  • the device 1B for maintaining negative pressure under the skin as illustrated appears to resemble a helmet having a hemispheric profile with its lower portion 21B which is placed on the skin and whose diameter is increased outward to some extent in the same manner as the brim of a hat.
  • the device 1B for maintaining negative pressure under the skin is not limited to that illustrated the drawings, but may be formed in the shape of an ellipse or polygon rather than a round shape in a plan view as seen from above or below.
  • the operation and usage of the present embodiment is the same as in the second embodiment, and therefore no redundant description is repeated. Since the stuck parts and adhesives used in the above embodiments respectively are used in direct contact with the skin, these are selected in order not to trigger allergies when used.
