Problems solved by technology

[0006] However, VSD technology still faces some problems to be solved in practice
VSD technology must use a special wound filling dressing, which requires the interior to be kept unobstructed to ensure that the tissue and exudate sucked out by negative pressure can be sucked out normally. The porous fiber material commonly used in my country is loofah. Strong tension, densely covered with a large number of gaps with a diameter of 0.2-1.0mm that communicate with each other. Although the appearance is similar to sponges, when encountering irregular or complex or uneven wounds, this material has the problem that it cannot be cut according to the size of the wound.
Therefore, not only the intact skin will be damaged by different negative pressure, but also the negative pressure will not be able to fully reach the wound that needs drainage, which seriously hinders the repair of the wound

Embodiment 1

[0025] An assembled negative pressure drainage filling dressing skeleton structure, including a flushing interface 1, a drainage outlet 2, and several dressing units with regular or irregular shapes connected to each other to form an overall structure that adapts to the shape of the wound; each dressing unit has a built-in At least one drainage connecting pipe is connected to each other to form a drainage circuit between the flushing interface and the drainage outlet. The flushing interface is connected with other drainage connecting pipes in sequence and finally reaches the drainage outlet. The side wall of the drainage connecting pipe is provided with several openings for drainage.

[0026] The shape of the drainage connecting pipe is any one or a combination of straight rod shape, Y shape, ring shape, arc shape and irregular shape. The dressing unit is any one or a combination of strips, circles, fans, polygons and irregular shapes.

[0027] The dressing body described in...

Embodiment 2

[0029] like figure 1 As shown, an assembled negative pressure drainage filling dressing skeleton structure includes a flushing interface 1 at one end, a drainage outlet 2 at the other end, and a plurality of rectangular dressing units arranged between the flushing interface 1 and the drainage outlet 2 31 are connected one by one to form an elongated overall structure. The dressing unit 31 includes a main body 310 and a drainage connecting pipe 311 that runs through the main body 310 along the midline. The drainage connecting pipe 311 is provided with a drainage branch pipe 312 buried in the free end of the main body 310 on both sides; the drainage connecting pipes 311 of a plurality of dressing units 31 are sequentially arranged. Connect to form a drainage circuit between the flushing interface 1 and the drainage outlet 2. In order to ensure the drainage effect, the drainage connecting pipe connected to the flushing interface 1 has an opening 313 on the side wall of the upstr...

Embodiment 3

[0033] like figure 2 As shown, this embodiment is a further improvement based on Embodiment 2. An assembled negative pressure drainage filling dressing skeleton structure includes a flushing interface 1 at one end, a drainage outlet 2 at the other end, and a plurality of dressing units 32 arranged between the flushing interface 1 and the drainage outlet 2 .

[0034] The dressing unit 32 includes a main body 322 and a drainage connecting pipe 323. The drainage connecting pipes 323 are connected one by one in the longitudinal direction, and there are drainage branch pipes 324 buried in the free end of the dressing body 322 on both sides. The drainage connecting pipes of multiple dressing units are connected in sequence to form a drainage circuit. .

[0035] The dressing body includes two types, one is a plurality of sheet-shaped bodies 320 distributed in the middle of the drainage circuit and combined to form an overall shape; the other is a long strip body that surrounds the ...

Abstract

The invention discloses an assembled negative pressure drainage filling dressing skeleton structure, which belongs to consumable products in the medical and health field. The structure has a flushing interface, a drainage outlet, and several dressing units with regular or irregular shapes connected to each other to form a wound surface adaptable The overall structure of the dressing unit; each dressing unit is connected to each other through at least one built-in drainage pipe, forming a drainage loop between the flushing interface and the drainage outlet. The present invention can flexibly change the shape and arrangement of the skeleton according to specific applications to meet wounds of different shapes, angles, and distribution areas.

Description

technical field [0001] The invention relates to the medical and health field, in particular to an assembled negative pressure drainage filling dressing skeleton structure. Background technique [0002] The concept of vacuum sealing drainage (VSD technology for short) was first created by Dr. Fleischmann of ULM University in Germany in 1992, and formed a theoretical prototype for the drainage of extremity wounds. In 1997, Morykways et al. found that the device can promote local blood circulation of the wound, promote the growth of granulation tissue in the wound, reduce the bacterial content of the tissue, and improve the survival rate of skin flaps or free skin grafts. Later, Moues et al. confirmed that the negative pressure sealing drainage technique significantly shortened the wound healing time compared with the traditional moist dressing dressing. Fbaian found through experimental research that negative pressure drainage can promote granulation tissue hyperplasia compar...
