An autotransfusion system for collecting blood from a patient and reinfusing the blood back into the patient is disclosed. The system includes a collection unit, a manually operable portable suction evacuator removably connected to the collection unit, and a blood reinfusion bag removably connected to the collection unit. The collection unit includes a collection chamber that is oversized relative to the volume of blood that the unit is intended to contain, and an airflow port located and oriented in the collection chamber to prevent blood from leaking into the port when the collection unit is oriented upright or on its side. When connected to the patient, the collection unit and portable suction evacuator are maintained free of blood by enclosing them within a substantially transparent, flexible envelope. The envelope enables the unit and evacuator to be connected and set-up for proper operation while preventing blood from contacting the outer surfaces of the unit and evacuator.

Autotransfusion system and method

A collagen fiber and methods for producing and using the collagen fiber of the inventions to prepare hemostatic fabrics to control bleeding are provided. The collagen particles (e.g., fibrils) of the fiber, preferably, have a hemostatic activity that is equivalent to the hemostatic activity of the collagen particles from which the fiber is formed. The collagen fibers of the invention and hemostatic fabrics formed thereof optionally include hemostatic agents and/or other therapeutic agents, to further promote hemostasis and wound healing.

Collagen hemostatic fibers

A blood processor for separating blood into cellular blood components and blood fluids including means for receiving a source of blood whose components are to be separated; means, operatively associated with the means for receiving, for separating cellular blood components from blood fluids, the means for separating including means for permitting passage therethrough of blood fluids but inhibiting the passage of blood components therethrough; a pulsating pump for pumping blood from the means for receiving into the means for separating and for agitating the blood within the means for separating; and, wherein the cellular components in the blood are inhibited from blocking the means for permitting passage, thereby facilitating the movement of blood fluids through the means for permitting passage.

Disposable blood washing and apheresis device and method of using thereof

A handpiece for a surgical irrigator and suction device includes a drip-free valve arrangement in which the portion of the flexible irrigation conduit is kinked in a V-shape. The handpiece carries a suction wand and an irrigation wand. The wands are easily detachable from the handpiece and can be substituted for wands having other configurations. A retainer clip is provided to prevent inadvertent separation of the wands. The irrigation wand may be used with a debridement nozzle which emits a plurality of distinct irrigation streams in a plane which provides an approved degree of manipulative control for the irrigation procedure.

Control handle for surgical irrigation and suction device

A control module for regulating the flow of gases in a suction drainage apparatus. The drainage apparatus includes a collection container in communication with a body cavity to receive body fluids (including liquids and gases) therefrom and a suction source for creating a negative pressure within the collection container and removing the gases of the body fluids. The control module includes a serial arrangement of chambers and a plurality of flow control means in a unitary compact structure which fits within a recess provided in the collection container. The control module is adapatable to different sizes and types of collection means and does not add appreciably to the overall size of the device. Baffle means are provided to prevent the loss of the indicator liquid from the air leak indicator means if the device is tipped in any direction.

Control module for thoracic drainage apparatus

An autotransfusion system for collecting and salvaging blood from a patient's body cavity and for returning it to the patient includes a collection bottle which is detachably connected by an arrangement of ports and an adapter to a source of suction as well as to a conduit from the patient. When the bottle is connected to the system the suction draws the blood into the bottle. When the bottle has been filled and it is desired to return the blood to the patient or for further processing before returning it to the patient the container is easily detached and may be connected to an intravenous delivery set. During reinfusion blood may continue to be collected by the system by replacing the original container with another container. The system may be operated by suction from commonly available fittings in hospital environments or may be connected to a thoracic drainage system to utilize the suction from that system to operate the autotransfusion device. The system may be formed from molded plastic materials and is adapted for disposable one-time use.

Autotransfusion system

A package and device for collecting urine wherein the parts comprising the device are packaged so that they are removed in the order that they are used and are maintained in a sterile condition prior to use. The device includes instructions, cleansing means, a container, funnel assembly, a cap for the container and an identification label packaged in such a manner so as to be sterile before use and removed aseptically in the order that such parts are used.
