Abstract
A disposable one-time use, inexpensive, capillary-action safety micro-pipet for obtaining a sample of blood or other liquid comprises a transparent glass tube which is capable of drawing blood or other liquid into the tube by capillary action, and a resilient sheet, with an adhesive layer adhering the resilient sheet in one or more layers around the outside surface of the tube for covering the outside surface of the tube and protecting a user against being cut by any jagged edges of a broken tube. The method of the invention comprises making a safety pipet by taking an elongated glass tube, taking a resilient sheet having an inner surface coated with a layer of adhesive, wrapping the resilient sheet around the outer surface of the tube and around inner layers of the resilient sheet, adhering the resilient sheet to the outer surface of the tube and to the inner layers of the sheet, to provide a wrapped safety glass tube in which the wrapping strengthens the tube against breaking and also protects the user against being cut by any jagged edges of a broken tube and from being infected by the contents of the tube which may be contaminated.
