Abstract: A method and device are disclosed for sampling cells of the human female reproductive tract. According to the method, cells can be collected and observed on the same surface. The device comprises a cell collection substrate and a support member to hold the substrate, and optionally a grasping member.

Abstract: An improved fibrin glue delivery system is disclosed. The delivery system is comprised of a pair of syringe tubes which can be actuated by plungers simultaneously or independently, a connecting member which holds the syringe tubes in parallel alignment and a unique needle assembly which ensures the components in the syringe bodies will not be comingled until they reach the treatment site. The unique needle assembly also permits the user to manipulate the needles to enhance visibility when the surgeon is working through a speculum or when direct access is difficult.

Abstract: A bone marrow transplant method and apparatus has been devised for the efficient recovery of bone marrow from a donor or patient by inserting a pair of aspiration needles at the intended site of removal and, through connection with a pair of syringes, the pressure is regulated to bring about selective removal of bone marrow and sinusoidal blood through one of the aspiration needles while positively forcing an intravenous solution through the other of the aspiration needles to replace the bone marrow removed from the site. The bone marrow and sinusoidal blood are drawn into a chamber for mixture with another intravenous solution and thereafter forced into a collection bag. A disposable assembly is provided for ready interchangeable use in association with a fluid flow and valve control unit in carrying out the method and principles of the present invention.

Abstract: The removal and separation of bone marrow cells for the purpose of analysis is carried out in a minimum number of steps by interposing a filtration chamber between a bone marrow needle and aspirator, withdrawing bone marrow particles together with sinusoidal blood through the filtration chamber so as to filter out or separate the bone marrow particles from the blood, and thereafter opening the filtration chamber to expose the particles for removal from the filter. The filtration chamber is constructed to define a fitting which can be releasably but sealingly connected at one end to the end of the needle and at the opposite end to the aspirator or syringe so that the necessary vacuum can be established and maintained for withdrawal of the specimen through the chamber without danger of contamination; and a seating surface within the chamber is so formed as to facilitate placement of a filter pad to collect the bone marrow particles and expose the particles for removal when the chamber is opened.

Abstract: A prepackaged coagulant composition and method of preparing same has been devised for use in direct or topical application to wounds so as to cause superficial clotting in which thrombin is combined with special preservatives and a saline solution. A ready-to-use bandage is saturated with the resultant solution, sealed and stored so as not to lose its reactive properties with the fibrinogen in the blood when applied to a wound or cut.
