Description
Technical Field
The utility model belongs to the technical field of medical instrument, more specifically relates to a negative pressure drainage device.
Background
Bodily system surgery includes breast surgery, thyroid surgery, etc., and the amount of drainage after such surgery is relatively small, requiring more accurate measurement of the amount of drainage. The wound surface is better in fitting degree through negative pressure suction, drainage is smoother, the wound is better in healing, the incidence rate of subcutaneous seroma can be reduced, the hospitalization time and the postoperative recovery time of a patient are reduced, and therefore the negative pressure drainage is basically the standard configuration of systemic postoperative drainage at present.
The principle of negative pressure drainage device at present clinically is to utilize spherical silica gel bag through the lasting negative pressure suction that produces from kick-backing after the compression by the drainage position, and this kind of sacculus negative pressure drainage device has three big drawbacks: (1) the drainage liquid directly enters the negative pressure drainage balloon, and under the condition that the negative pressure drainage balloon is compressed, the quantity of the drainage liquid is difficult to judge through the scales on the balloon; when the drainage is measured every day, the negative pressure drainage balloon needs to be separated from a drainage tube connected with the surgical wound surface, so that the balloon is restored to an expanded natural state, and the drainage quantity can be read through the scales on the balloon; in the drainage liquid metering process, after the surgical wound drainage tube is separated from the balloon, the tube cavity of the surgical wound drainage tube needs to be exposed in the air for a period of time, so that the possibility of surgical area infection caused by liquid backflow in the main drainage tube is increased; (2) when the negative pressure drainage balloon leaks air or a large amount of drainage liquid enters, the balloon is restored to a natural state, and then the negative pressure disappears, and at the moment, if the negative pressure cannot be found in time, the drainage of the surgical wound surface is seriously influenced, and even the occurrence of retrograde infection is caused; (3) systemic surgery, particularly complex breast reconstruction surgery, often causes poor drainage due to blockage of side holes in the operation area of a main drainage tube by fallen fat particles, the situation often needs to be flushed, the conventional main drainage tube does not provide a flushable pipeline, and the possibility of retrograde infection still exists when the main drainage tube is directly flushed. For systemic surgery, where aseptic manipulation is an important prerequisite, conventional negative pressure drainage devices certainly increase the chances of infection, particularly in breast reconstruction surgery involving self or prosthesis, with serious consequences once infected.
