Continuous negative-pressure drainage device capable of intermittently inflating and flushing

Abstract

The invention provides a continuous negative-pressure drainage device capable of intermittently inflating and flushing and belongs to the technical field of medical instruments in the orthopedics department. The device is used for continuous negative-pressure drainage, that is, inflating and flushing are intermittently conducted on the surface of a wound. The device is characterized in that a negative-pressure drainage pipe is connected with an inflating pipe and a flushing water pipe, an air inlet end of the inflating pipe and an water inlet end of the flushing water pipe are connected with an oxygen delivery pipe and a flushing water pipeline respectively, the inflating pipe and the flushing water pipe are provided with electric control valves respectively, and the electric control valves are connected with a programmable controller respectively. According to the device, oxygen and physiological saline are supplied intermittently, anaerobic bacteria infection can be inhibited, exudate and contaminated tissue can be cleared away, repeated debridement is avoided, when oxygen supply and flushing are conducted, a continuous negative pressure environment can be created, exudate and necrotic tissue of the wound can be timely cleared away and drained, the local microcirculation is improved, relieving of edema of soft tissue is promoted, the growth of granulation tissue is stimulated, wound healing is accelerated, a good condition is provided for the follow-up treatment, and the treatment process is sped up.

Description

technical field

[0001] The invention relates to a device capable of intermittently giving oxygen to the wound surface, intermittently flushing, and continuously performing negative pressure drainage, and belongs to the technical field of orthopedic medical devices. Background technique

[0002] At present, in orthopedic medical clinics, the incidence of various high-energy injuries such as open fractures caused by various traffic accidents, industrial accidents, sports injuries, and travel and adventure accidents is increasing day by day. This type of injury fracture is severely displaced and comminuted, and the surrounding muscles, ligaments and other soft tissues are severely damaged. During the treatment, for open fractures, there are often a large number of bone defects, soft tissue defects, and pollution, which require repeated debridement treatments; for closed fractures, if the diagnosis and treatment are improper, or the operation time is too early, wound infection i...
