Patent number: 4652261Abstract: A drug-injection animal collar includes electrically operated drug injection darts or syringes that are controlled by control circuitry mounted on the collar which may be preset and self-timed and actuated, or may be remotely actuated by radio signals. The collar is placed on the neck of an animal and upon receipt of a signal, a suitable drug is injected into the neck muscles of the animal. The collar and its method of operation allow regular recapture of individual animals at will for research purposes. The collar and darts may be reconditioned and then reused. The power for operation is also contained in the control package carried by the collar.Type: GrantFiled: June 22, 1984Date of Patent: March 24, 1987Assignee: Regents of the University of MinnesotaInventors: L.

Patent number: 4644941Abstract: A splint device for the immobilization of a preselected portion of the body, such as a digital member. The splint device preferably comprises a splint means comprising a ring-like base portion adapted to fit snugly around a digit in proximity to its proximal end. Extending from the base portion there are provided a plurality of essentially rigid elongated support members which are spaced apart around the base portion so as to immobilize the contained digit, preferably on more than one of its sides, each of the support members terminating at a free end which is in the vicinity of, or beyond the distal end, of the digit. The ring-like base portion is preferably expandable. The splint device may also comprise restraining means which may be positioned around the support member for retaining the support members adjacent the digital member, and an end cap which may be positioned on the free ends of the support members.Type: GrantFiled: May 15, 1985Date of Patent: February 24, 1987Inventor: George B.

Patent number: 4643713Abstract: A venous reservoir is provided in which a blood inlet (42) is located at an inlet end (70) of the container (48) which extends upwardly with a fast rise and for a sufficient distance to allow the blood entering the inlet to enter a large volume and to expand rapidly. The top (74) of the inlet end wall (70) of the container communicates with a vent outlet (46) whereby a sharp decrease in the velocity of the blood flow resulting from its rapid expansion provides buoyancy to air in the blood causing air bubbles to rise to the top of the container and be vented through the vent opening. A top wall (76) of the container extends from the vent opening and toward a blood outlet (44), with the top wall being curved in a manner to prevent the velocity of blood from increasing until the blood is substantially at the blood outlet.Type: GrantFiled: November 5, 1984Date of Patent: February 17, 1987Assignee: Baxter Travenol Laboratories, Inc.Inventor: Daniel W. Viitala

Patent number: 4613329Abstract: A catheter placement device is provided which includes an adapter with an elastomeric grommet having a bore through which a pliable catheter is fed into a blood vessel of a patient. The grommet has a flange engageable with the catheter and effects a relatively low resistance to distal movement of the catheter and relatively high resistance to proximal movement of the catheter. A pair of adapters may be used with one adapter carrying a grommet and the other having a frusto-conical bore receiving an end of the grommet. The adapters are relatively rotatable to cause the grommet to lock the catheter against axial movement relative to the adapters. Retention members may be used to prevent inadvertent separation of the adapters during relative rotation.Type: GrantFiled: September 30, 1983Date of Patent: September 23, 1986Assignee: Sherwood Medical CompanyInventor: Raymond O.

Patent number: 4606735Abstract: A detachable holder for immobilizing a flexible tubing at a site adjacent its point of connection to a medical device inserted in a patient to feed a therapeutic fluid into a vein or artery or to withdraw fluid from the patient. The holder is formed by a flexible plastic strip having upstanding end wings provided with snap-in key hole slots in axial alignment. These slots are adapted to receive a short section of the tubing which then bridges the wings and is held thereby. Attached to the underside of the strip is one component of a hook and loop fabric fastener whose other component is bonded to the outer face of an adhesive tape. By adhering the tape to the skin of the patient at a position adjacent the inserted medical device and then fastening the holder thereto, one is able to immobilize the tubing to prevent a tug thereon from displacing the inserted medical device.Type: GrantFiled: September 24, 1984Date of Patent: August 19, 1986Inventors: Joseph R. Wilder, Franklin G. Reick
