Abstract

There is disclosed an instrument for cutting bandages which has a handle and a base guide foot section. The base guide foot has a nose section which extends past the edge of a blade positioned within the instrument. The base guide unit has an enlarged portion on its bottom area which permits the instrument to ride on only a small area and be pivoted on the area when in use. In one version the instruments has a removable blade unit which can be installed and removed without being contacted by the installer thereby reducing possibility of contamination.

Claims

1. An instrument for cutting bandages comprising an elongated handle, a guide foot elongated in the same direction as the handle and constructed at an angle to said handle, a blade within said handle and guide foot, a pivot area on the lower part of said guide foot, a nose end on said guide foot, said pivot area including an enlarged area on the lower part of said guide foot between the blade and the nose end constructed to contact the body from which a bandage is to be cut, thereby allowing the operator of said instrument to maneuver the guide foot under a bandage with only a minimal area of said instrument contacting a body part from which the bandage is being removed.

2. The instrument of claim 1 wherein the blade is permanently fixed in the instrument.

3. A bandage cutter constructed of a material which can be repeatedly sterilized, comprising an elongated handle, an elongated guide foot, a mouth formed by the handle and upper part of the guide foot, a cavity in said mouth, a blade ejector means in said cavity, said blade ejector means extending externally of said elongated handle, a fixed blade base in said cavity, said fixed blade base having a passageway through which the blade ejector means travels, notches in said fixed blade base for receiving corresponding elements of a blade unit which snap into said notches and hold the blade unit in place whereby the blade unit can be inserted and removed from the bandage cutter.

4. The bandage cutter of claim 3 wherein said fixed blade base is shaped with inwardly slanted sides toward the top so legs of the blade unit fit snugly over said fixed blade base.

5. The bandage cutter of claim 3 in which said blade ejector means is fastened centrally of said handle and when an externally extending means of the ejector means is pushed toward the cavity the blade ejector means recesses into said handle, then when the extending means is pulled away from the cavity the blade ejector means travels through the passageway in the fixed blade base and contacts the blade unit for removing said blade unit.

6. The bandage cutter of claim 3 further including a bottom on said guide foot, an enlarged area on said bottom which permits the bandage cutter to be maneuvered when in use.

7. In combination, a blade unit and a bandage cutter instrument, said blade unit having a blade, legs fastened to said blade and spread to form a saddle shape, locking elements on the end of each leg opposite the blade, and a cap on said blade;

said bandage cutter instrument being constructed of a material capable of being repeatedly sterilized and having a handle joined at an angle with a guide foot section, said guide foot section having an enlarged area on its bottom and a nose section, said instrument having a mouth and a cavity formed in said mouth between said handle and said guide foot section, said cavity having a blade base fixed therein, said blade base being shaped to fit snugly between the legs of said blade unit, said blade base having notches in which the locking elements of said blade unit fit, said blade base having a passageway centrally thereof through which a blade ejector passes downward to permit insertion of the blade unit and passes upward to eject the blade unit, said blade ejector being positioned central of the handle and having a portion extending above the top of the handle whereby when the portion of the ejector extending externally of the top of the handle is pushed forward, the blade unit can be pushed into the cavity and over the blade base until the blade unit fastens in place over the blade base, and after use, the ejector is pulled backward to eject the blade unit from the cavity.

8. The combination of claim 7 wherein the bandage cutter instrument is constructed of stainless steel.

9. A method for cutting a bandage comprising the steps of selecting a cutter having a handle, a guide foot, a mouth with a cavity and a blade ejector in said cavity, selecting a sterile blade unit having a blade, a cap for said blade, and legs including means to lock said blade unit into said cutter;

holding the blade unit by the cap and pushing said cap into said cutter mouth until it locks in place within the cavity, providing a nose end on said guide foot and providing an enlarged area on the bottom of said guide foot near the nose end, placing the nose end under the bandage, pushing downward on the handle until the cutter rests only on the enlarged area, then moving the instrument forward to move the blade into the bandage, and pivoting the cutter from side to side to guide around tender or sore parts of a body, continuing the movements until the bandage has been severed;

turning the bandage cutter instrument over a disposal and engaging said blade ejector to eject said blade unit, thereby minimizing chances of contamination.
