Description

Multifunctional negative pressure flushing drainage tube

Technical Field

The utility model relates to equipment in the field of medical instruments, in particular to a multifunctional negative pressure flushing drainage tube.

Background

In China, maxillofacial space infection is a common clinical disease, and serious consequences such as mediastinitis, necrotizing fasciitis, septicemia, osteomyelitis and the like can be caused if the maxillofacial space infection is not intervened in time, and even the patient with inflammation oppressing the airway can threaten life. At present, the traditional treatment method for the infection of the maxillofacial gap is to place a drainage tube at the pus cavity of a patient to establish a drainage channel after incision and pus discharge, and the traditional drainage tube only relies on gravity for drainage and needs a clinician to manually wash at least once every day after operation, so that the effective clinical effect can be ensured. In clinical practice, the above-mentioned conventional treatment regimens have the following drawbacks: the workload of doctors is large; the drainage which only depends on the gravity cannot achieve the continuous flushing effect, and the clinical treatment effect is poor; the necrotic tissue fragments easily block the drainage tube, affecting the drainage effect.

Chinese patent documents: CN203090204U discloses a double-cavity negative pressure drainage tube, which mainly comprises an outer tube with a closed end and an opening at the other end and a hollow inner tube with openings at both ends; the length of the inner pipe is larger than that of the outer pipe, one end of the inner pipe is arranged in the outer pipe, but the bottom ends of the inner pipe and the outer pipe are not contacted; the other end extends out of the outer pipe; the wall of the outer tube is provided with a plurality of drainage holes. When intestinal juice is in the abdominal cavity, the intestinal juice enters the gap between the inner tube and the outer tube from the drainage hole of the outer sleeve tube and is sucked by the inner tube with negative pressure. When there is no liquid in the abdominal cavity, the suction tube sucks air entering from the gap between the inner tube and the outer tube. Therefore, the tissues and organs in the abdominal cavity are not in direct contact with the inner tube with negative pressure, and the tissues cannot enter the negative pressure tube to be damaged. The drainage tube can effectively prevent the suction tube cavity from being blocked by pus or tissue fragments to a certain extent, and is combined with negative pressure suction drainage, but continuous flushing is not used, and the flushing effect is not good. And the drainage tube has a single function, and cannot provide relevant treatment for patients suffering from anaerobic bacteria infection.

Chinese patent documents: CN210813414U discloses "a double cannula for medical drainage, which comprises an inner tube and an outer tube, wherein the inner tube is sleeved in the inner cavity of the outer tube, and one end of the inner tube passes through the side wall of the outer tube and extends out of the outer tube; the outer tube is provided with a through hole, the through hole is communicated with the inner cavity of the outer tube, and a plug is connected to the through hole. The double-cannula for medical drainage provided by the utility model can meet the requirements of natural drainage and negative pressure drainage, avoid the manual addition of side holes and prevent infection. The utility model can realize negative pressure continuous suction drainage, but the structure of the front end of the drainage tube arranged in the pus cavity is not clearly described, so that the blockage of the drainage tube opening still exists, the drainage efficiency is reduced, and the utility model is not beneficial to patients with high pus viscosity and more tissue fragments in the pus cavity.

In summary, there is a need for a multifunctional negative pressure irrigation drainage tube which can provide continuous negative pressure suction drainage and continuous abscess cavity irrigation, can ensure that a drainage channel is not blocked and can be always kept smooth, and can provide a channel for targeted adjuvant therapy.
