Medical measuring device and method
View Patent ↗A subsurface wound measuring device and method are provided for measuring a subsurface wound or cavity of a patient, the device including a flexible strip having first and second sections, the sections having first and second ends respectively with an intermediate bend being located between the first and second ends. The first end is adapted for being located internally to a patient, the second end being adapted for being located externally to the patient. The first and second sections have generally concave-shaped cross-sections with measuring indicia being located along at least one of the sections. The device also optionally includes a measuring strip and a receiver mounted on the second end for receiving the measuring strip, where the measuring strip and the flexible strip form complementary structure for measuring a subsurface wound or cavity.
1. A wound measuring method for measuring at least one physical parameter of a patient with a subsurface wound having a cavity with a cavity opening and a sidewall, said method comprising:
providing a measuring device with a flexible measuring strip having a first end, a second end and an exterior surface with measuring indicia;
providing said measuring device with a flexible guide strip having a first end, a second end and an exterior surface;
providing each said strip with a generally arcuate, concave, transverse, cross-sectional configuration;
providing a collar or sleeve with a passage extending therethrough;
slidably receiving said measuring strip in said collar or sleeve passage in a frictional, gripping relation;
inserting the flexible guide strip at least partially into the cavity by the flexible guide strip second end, the second end extending towards the cavity opening, the first end extending towards the cavity sidewall;
inserting the flexible measuring strip at least partially into the cavity in sliding contact on the guide strip with the measuring strip first end extending towards the cavity sidewall;
locating the measuring device in association with the cavity sidewall;
identifying a distance along the cavity sidewall with the measuring indicia;
forming a bend in the flexible measuring strip at a variably repositionable bend location between said measuring strip first and second ends;
relating the bend location to a dimension of the cavity;
dividing said flexible measuring strip at said bend into first and second semi-rigid sections terminating at said first and second strip ends respectively;
moving the collar or sleeve into position in proximity said bend to maintain the bend and to provide a visual reference for the bend location along the flexible measuring strip, and further to lock the position of the flexible measuring strip in place;
identifying the distance with said first and second semi-rigid sections extending along respective portions of said cavity;
recording the distance;
providing a receptacle with a closed end at the measuring strip first end;
providing the receptacle with an opening in spaced relation and oriented away from said measuring strip first end;
obtaining a tissue or fluid sample in said receptacle from within said wound; and
extracting said sample from the wound and analyzing said sample.
2. The wound measuring method according to claim 1 , which includes the additional step of providing said receptacle with a radiused configuration.
