Abstract: A method of measuring blood clotting ability of a patient. A known volume of blood is dispensed on a reference disc of blotter paper, such that at least one reference blotch is formed on the reference disc. The surface area of the reference blotch formed on the reference disc, such that a relationship between the volume of blood and the surface area of the reference blotch can be obtained. An incision is made at the patient. A piece of blotter paper to the incision is applied to the incision to collect blood flowing therefrom, such that at least one blotch is formed on the piece of blotter paper. The surface area of the blotch formed on the piece of blotter paper is measured. The volume of the blood absorbed blood by the blotter paper is calculated according to the relationship between the blood volume and the surface area of the blotch.

Abstract: A peristaltic pump system includes elastomeric pump tubing and a roller pump. The pump tubing has a pumping segment and an inlet segment. The inlet segment has an inlet segment outer diameter. The pumping segment has a pumping segment outer diameter less than the inlet segment outer diameter. The roller pump has a roller assembly and a roller assembly housing. The roller assembly is disposed within the roller assembly housing and engaged with the pumping segment within the roller assembly housing. The roller assembly housing has an inlet gap formed through the roller assembly housing. The inlet gap defines an inlet gap inner diameter smaller than the pumping segment outer diameter. The inlet gap is adapted to frictionally receive the inlet segment for aligning the pump tubing with a roller assembly and mitigate longitudinal movement of the pump tubing into the roller assembly housing.

Abstract: An infiltration cannula and method of using the infiltration cannula during a tumescent infiltration procedure are disclosed herein. The infiltration cannula may have an outwardly flaring hub which may be wedged into an adit of a patient to minimize leakage of fluid being infiltrated into the patient. Also, the infiltration cannula may be utilized to hydrate a dehydrated patient by a medically untrained person. The infiltration cannula may also be used to deliver an antibiotic/vasoconstrictive drug solution to minimize surgical site infections.

Abstract: A system is described for breast imaging that includes spatially registering sequential mammographic images of the same breast. The system includes a first compression member configured to contact a first side of a breast, a second compression member configured to contact a second side of a breast that is substantially opposite the first side. The system further includes a first image sensor, coupled to the first compression member and configured to detect a position of a first fiducial marker located at the first side of the breast, and a second image sensor, coupled to the second compression member and configured to detect a position of a second fiducial marker located at the second side of the breast.

Abstract: An infiltration cannula and method of using the infiltration cannula during an infiltration procedure are disclosed herein. The infiltration cannula has a flexible cannula and a hub. The cannula has a proximal end and a distal end. The cannula also has a plurality of apertures disposed in a pattern about the distal end. The apertures are configured to infiltrate fluid into the subcutaneous or muscle tissue of a patient. The hub is configured to be held by a person performing the infiltration procedure. The hub has a first end and an opposing second end. The first end is attached to the proximal end of the flexible cannula and the second end includes a connector configured to connect to an input source for receiving the fluid to be infiltrated into the subcutaneous tissue of the patient. The fluid flows from the connector, through the hub and into the cannula.

Abstract: An infiltration cannula and method of using the infiltration cannula during an infiltration procedure are disclosed herein. The infiltration cannula includes: a tubular needle and a hub. The tubular needle has a proximal end and a distal end. The tubular needle also has a plurality of apertures disposed in a pattern about the distal end. The apertures are configured to infiltrate fluid into the subcutaneous tissue of a patient. The hub is configured to be held by a person performing the infiltration procedure. The hub has a first end and an opposing second end. The first end is attached to the proximal end of the tubular needle and the second end includes a connector configured to connect to an input source for receiving the fluid to be infiltrated into the subcutaneous tissue of the patient. The fluid flows from the connector, through the hub and into the tubular needle.

Abstract: A method for accelerating subcutaneous absorption of a fluid or drug into the systemic circulation of a specific targeted tissue. A first drug operative to produce local capillary vasodilatation and/or increase the rate of bulk flow of solution through the interstitial space is mixed with a fluid. The fluid may contain a crystalloid solution or a dilute solution of a pharmacologic drug required for a routine or emergency therapeutic treatment for a patient. The first drug is substantially non-toxic to the patient. The fluid mixed with the first drug is then delivered subcutaneously or into deeper tissues of the patient, by use of a hyperdermic needle or infiltration cannula. As the capillaries are dilated, the fluid is efficiently absorbed and circulated systemically.
