Abstract

A method and apparatus for aspirating secreted fluids from a wound is disclosed which involves the placement of a drain into a wound via the tissue adjacent the wound. After the wound is closed, a secretion aspiration and collection device, which is connected to the drain via a tube, is placed into operation. The device is designed to have a suction effect controlled between a minimum value and a maximum value according to the quantity of secreted fluid to be aspirated. This is achieved by one or more sensors which control a tube pump. When a second sensor is used, the pump will not be shut off by a passing air bubble in the fluid. A sleeve may also be provided to facilitate introduction of the drain into the wound. Additionally, a needle may be detachably connected to the sleeve to aid the insertion of the sleeve.

Claims

1. The method for placing a drain in a wound, comprising the steps of:

(a) introducing a sterile sleeve into the tissue adjacent the wound from the wound side of the tissue;

(b) pushing said sterile sleeve outward through the tissue toward a body surface defining an outward surface of the tissue in such a manner that a forward end of said sleeve projects above said body surface and a rear end of said sleeve still lies in the wound;

(c) introducing said drain into the wound through the forward end of said sleeve projecting above said body surface;

(d) withdrawing said sleeve outwardly from the tissue.

2. The method of claim 1 further comprising a method for aspirating secreted fluid out of said wound further comprising the steps of:

(a) connecting said drain via a tube with a secretion aspiration and collection device to form a sterile system;

(b) closing said wound;

(c) parting said sleeve longitudinally after withdrawing said sleeve from the tissue;

(d) removing said sleeve from said tube connecting said drain with said secretion aspiration and collection device; and

(e) placing said secretion aspiration and collection device into operation.

3. The method of claim 2 further comprising the steps of:

(a) using a sterile needle detachably connected to the forward end of said sleeve to facilitate said step of introducing said sleeve into said tissue; and

(b) detaching said sleeve from said needle.
