Detailed Description

As shown in fig. 1 to 3, the present embodiment provides a removable drainage device. Specifically including setting up dressing 2 that is used for adsorbing surface of a wound shallow exudate on surface of a wound 1, set up in the pad pasting 3 in dressing 2 outsides, the used pad pasting of this embodiment is the biological semipermeable membrane, and this biological semipermeable membrane can be in order to guarantee that the liquid in the dressing does not ooze outward, can keep good gas permeability again. The drainage device also comprises a drainage tube 4, one end of which is inserted in the deep part 8 of the wound surface, and the other end of which penetrates through the dressing 2 and is hermetically arranged with the pad pasting 3.

As shown in fig. 1, the drainage tube of the present embodiment is a removable drainage tube, and after the drainage is completed, the drainage tube can be removed without moving the dressing and the film, so that the replacement frequency of the drainage device is reduced, the probability of cross infection of the wound surface is reduced, and the drainage device has a simple structure and is convenient to operate.

As shown in figure 3, the cross section of the drainage tube 4 is of a cross structure, under the action of negative pressure, necrotic tissues or exudates in the wound surface flow in the direction shown by the arrow in figure 1 and are sucked into the drainage tube from different directions, so that the drainage area is enlarged, the drainage effect is improved, and the drainage time is shortened. In addition, due to the cross-shaped structure of the cross section, the problem that the drainage tube is easy to block in the using process is solved, and the drainage efficiency is improved.

As shown in fig. 1 and 2, a suction cup 81 is further disposed on the upper portion of the dressing 2, and a through hole for the drainage tube 4 to pass through is formed on the suction cup 81; the side of the suction cup 81 is further provided with a negative pressure suction device, which comprises a suction tube 5, and further comprises a control structure for controlling the opening and closing of the suction tube 5, namely a three-way structure 6 and a valve 9 matched with the three-way structure.

The above-mentioned structural design of this embodiment all sets up the drainage tube on the sucking disc with the mouth of pipe of attracting the pipe, has simplified whole drainage device's structure, has reduced the shared space area of device, has improved the convenience of using.

As shown in fig. 2, the suction tube 5 is a double suction tube, the double suction tube 5 is communicated with the same side of the suction cup 81 and is respectively provided with a control structure, namely, each suction tube 5 is provided with a three-way structure and a valve, so as to achieve the purpose of tube division control and tube division, and further change the flow direction of liquid and gas in the drainage tube by changing the opening size of the three-way valve, thereby realizing the flushing of the suction tube and the suction cup.

When not needing the degree of depth drainage, can extract the drainage tube, with sealed lid sealing connection in opening part, can let whole device still closed condition, blocked the chance that the surface of a wound contacted with external environment, reduced the probability of surface of a wound infection, shortened treatment time.

As shown in fig. 1 and 2, a suction cup base plate 8 is further arranged between the suction cup 81 and the dressing 2, and the covering surface of the suction cup base plate 8 is larger than that of the suction cup. The arrangement of the sucking disc base plate 8 further ensures the tightness of the connection between the drainage tube and the suction tube and between the dressing, reduces the probability of cross infection of the wound surface and improves the speed of wound healing.

Since the polyurethane sponge is a porous foam material, soft and elastic in texture, and has good plasticity and air permeability, the polyurethane sponge is preferably used as the dressing in this embodiment.

The utility model discloses a concrete application as follows:

step one, placing a drainage tube. 1. Debridement: completely remove necrotic inactivated tissue or easily necrotic tissue, abnormal secretion, foreign matters and the like of the wound surface, open all cavities, ensure blood supply of soft tissue and bone tissue, and clean the skin around the wound surface. 2. Preparing drainage materials: and trimming the dressing into which the drainage tube and the negative pressure suction tube are inserted according to the size and the shape of the wound surface. The cross section of the drainage tube is of a cross-shaped structure. The direction of the drainage tube outlet pipe is based on the principle of facilitating the sealing of the drainage tube. 3. Filling: covering and filling the dressing, and sewing and fixing the dressing to ensure that the dressing completely covers the wound surface. When the wound surface is deep, the dressing needs to be filled to the bottom, and no dead space is left in the wound surface.

And step two, sealing. The negative pressure sucker chassis is adhered to the dressing, the sucker is arranged on the sucker chassis, then the drainage tube is placed into the wound cavity through the openings of the sucker and the sucker chassis, and the dressing and the outer side of the negative pressure sucker are covered with the sealing adhesive film.

And step three, connecting negative pressure. One end of the negative pressure suction tube is hermetically connected with the opening of the sucker, and the other end is connected with a negative pressure device (not shown in the figure). The negative pressure is adjusted to a suitable value.

And step four, after the normal negative pressure closed drainage is ensured, observing and recording the negative pressure condition and the character and quantity of the effluent. When drainage through the drainage tube is not needed, the negative pressure device is closed, the sealing cover is opened, the negative pressure suction tube is taken out, then the sealing cover is covered on the end part of the drainage tube to enable the drainage tube to be in a sealing state, and finally the negative pressure device is opened. And when the negative pressure drainage is not needed, removing the negative pressure drainage device. The device is simple to operate and high in practicability.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation.
