The invention is directed to a surgical wound retractor for retracting and sealing an incision and forming a functional opening or channel through which a surgical procedure may be executed. The wound retractor provides a path for a surgeon to insert his hand and / or instruments through the opening formed by the wound retractor. The wound retractor is sized and configured to be easily placed through a small incision and removed without further insult to the body tissue adjacent to the incision. The wound retractor is adapted to dilate a surgical wound incision to a desired diameter, and comprises a first ring having a diameter greater than the desired diameter of the wound incision and being adapted for disposition interiorly of the wound incision; a second ring having an annular axis and a diameter greater than the desired diameter of the wound incision and being adapted for disposition exteriorly of the wound incision; and a flexible sleeve disposed in a generally cylindrical form between the first ring and the second ring, the first ring having at least one notch to facilitate folding or collapsing of the first ring during insertion and removal of the first ring through the wound incision. The first ring may further comprise a second notch disposed on an opposing end of the first notch to further facilitate folding or collapsing of the first ring. With this aspect, the first ring is folded by squeezing between the first and second notches during insertion and removal of the retractor from the incision. In another aspect, the wound retractor may further comprise a tether having a length, a first end attached to the first ring interiorly of the sheath, and a second end disposed outside of the wound incision, wherein the tether facilitates removal of the first ring by pulling on the second end to retrieve the first ring through the wound incision.

Several techniques are disclosed for isolating either heart or breath rate data from a photoplethysmograph, which is a time domain signal such as from a pulse oximeter. The techniques involve the use of filtering in the frequency domain, after a Fast Fourier Transform (FFT) has been conducted on a given photoplethysmograph also references as a given set of discrete time-domain data. The filtering may be applied to an identified fundamental frequency and one or more harmonics for heart related parameters. The filter may be truncated to the frequency data set and further applied multiple times to improve roll off. After filtering, an Inverse FFT (IFFT) is used to reconstruct the time-domain signal, except with undesirable frequency content eliminated or reduced. Calculation or measurement of parameters is then conducted on this reconstructed time-domain signal.
