Problems solved by technology

However, this negative pressure drainage dressing can only carry out negative pressure suction. Once the wound secretion is thick and thick, it is difficult to be sucked out or adsorbed on the spongy body to block its micropore structure, and even the negative pressure suction tube is blocked, resulting in Vacuum suction failure
In addition, all the negative pressure suction devices currently on the market do not have the effect of intervening on the wound surface

no. 1 example

[0025] The first embodiment: as Figure 1 to Figure 2 as shown,

[0026] A negative pressure drainage dressing with suction and flushing functions, comprising a sponge body 1 and at least one drainage catheter 2, one end of the drainage catheter 2 is inserted into the sponge body 1, the other end is connected to a negative pressure source, and the drainage catheter 2 is inserted into the sponge body 1 There are several negative pressure suction through holes 3 on the catheter tube wall, wherein: the negative pressure drainage dressing also includes a perfusion pipeline 4, and the perfusion pipeline 4 is inserted into the sponge body 1 and can inject flushing liquid or medicinal liquid into the sponge body 1 To intervene on the wound, the drainage catheter 2 can absorb the wound exudate, rinsing liquid and medicinal liquid in the spongy body 1 under negative pressure.

[0027] In the embodiment, the number of drainage catheter 2 is one.

[0028] In the embodiment, the negativ...

[0032] The second embodiment: as Figure 3 to Figure 4 as shown,

[0033] In the embodiment, the perfusion pipeline 4 includes a main pipe 41 and a branch pipe 42. The branch pipe 42 is placed in the sponge body 1, and the end of the branch pipe 42 is connected to the main pipe 41. There are several injection holes on the wall of the branch pipe 42, so that the perfusion pipe 4 injects The irrigating liquid or medicinal liquid can be evenly sprayed to every place in the spongy body 1 .

[0034] In the embodiment, the branch pipes 42 are arranged in a net shape in the sponge body 1 .

[0035] In the embodiment, the branch pipe 42 is several horizontal and vertical interconnecting pipelines.

[0036] In an embodiment, the injection hole is arranged at the intersection of the horizontal pipeline and the vertical pipeline.

[0037] In this embodiment, the sub-pipes 42 of the perfusion pipeline 4 are laid out in a net shape, allowing the perfusion pipeline 4 to extend to every c...

[0039] The third embodiment: as Figure 5 to Figure 6 as shown,

[0040] In the embodiment, the branch pipe 42 is arranged in the shape of leaf veins in the sponge body 1 .

[0041] In the embodiment, the branch pipe 42 includes a thick branch pipe 42a. The thick branch pipe 42a diverges to several subdivided pipes 42b around the spongy body 1. Both the thick branch pipe 42a and the subdivided pipe 42b are provided with injection holes.

[0042] In this embodiment, the branch pipes 42 of the perfusion pipeline 4 are arranged in the shape of leaf veins, allowing the perfusion pipeline 4 to extend to every corner of the sponge body 1 for uniform injection, so that the medicinal liquid can be evenly dispersed in the entire sponge body 1 without It may happen that some wounds are intervened by liquid medicine, and some wounds are not in contact with liquid medicine.

[0043] The parts not described are the same as the first embodiment.

Abstract

The present invention discloses a negative pressure drainage dressing having attraction and flushing functions. The negative pressure drainage dressing comprises a sponge body and at least one drainage conduit; one end of the drainage conduit is inserted into the sponge body; the other end of the drainage conduit is connected with a negative pressure source; and a conduit wall of the drainage conduit inserted into the sponge body is provided with a plurality of negative pressure attraction through holes. The negative pressure drainage dressing also comprises a perfusion pipeline, the perfusion pipeline is inserted into the sponge body and capable of injecting flushing liquid or soup into the sponge body to intervene in a wound, and negative pressure attraction of the wound secretion, the flushing liquid and the soup in the sponge body can be carried out by the drainage conduit. The negative pressure drainage dressing has the advantages that the liquid can be injected to the wound, the wound can be wetted and cleaned, the efficiency of attracting the secretion and edema liquid is higher, the wound can be intervened, and inhalation channels are not easy to be blocked.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a negative pressure drainage dressing with suction and flushing functions. Background technique [0002] The wound-closed negative pressure treatment technology is based on the traditional clinical negative pressure treatment method. The wound is placed with a medical sponge, the wound is sealed with a biological transparent film, and then the medical sponge and the wound are sealed with a semi-permeable film to form an airtight environment. The drainage system prevents the invasion of external bacteria, improves the blood flow rate of the wound microcirculation, expands the capillaries, and promotes the growth rate of granulation, thereby increasing the effect of rapid wound healing. Wound sealing negative pressure therapy technology is a new wound treatment technology developed in recent years, especially for patients with burn (wound) injuries and chronic refractory wo...
