摘要： The specific disclosure provides a device and method of making an incision of precise dimensions in a patient, preferably in the forearm, and determining exact bleeding from initial puncture of the skin until the flow of blood has ceased, i.e. hemostatis is complete. The device comprises a housing including a blade aperture at one end thereof adapted to be positioned in abutting engagement with the skin of the subject. A spring member and a blade member having at least one cutting edge are located in the housing. Means are also provided in the housing and is connected to the blade member for retracting the blade member inwardly from the blade aperture and against the bias of the spring member. Manually operable means are provided for releasably engaging the retracting means to maintain the blade member in a retracted position against the bias of the spring member until the device is ready for use. The engaging means is manually operable to irretrievably disengage the retracting means, thereby permitting the retracting means and the blade member to move under the bias of the spring member to position the at least one cutting edge a predetermined distance outwardly from the blade aperture.

摘要： A cleaning mechanism for a flexible, twin-blade, wet-shaving unit designed to remove the debris that becomes lodged between the blades during shaving. The cleaning mechanism may be employed with a flexible razor units having a "slim" configuration and a centrally-fixed securing post extending through the unit. The cleaning mechanism includes an ejector bar operable between an advanced position and a retracted position and a pair of actuation return members for biasing the ejector bar to the retracted position.
