Abstract: A siphoning device suited for automatically removing fluid/blood from a surgical site is described, having a length of sterile flexible tubing that is configurable into a loop, the tubing having a first open end, a second open end, and a central portion. A plurality of holes punctuate the circumference of either the first open end or the central portion of the loop, the one or more sets of holes being distributed along a longitudinal direction of the tubing. A sterile absorbent covering encompasses the one or more sets of the plurality of holes, the covering being permeable to bodily fluids. The siphoning device is connected to a vacuum system that generates a negative pressure, causing fluids that have accumulated in the absorbent covering to be withdrawn into the vacuum system. Accordingly, a durable, simple non-gauze system for automatically clearing blood/fluid from a surgical site is described.

Webbing extends between the lip retractors and cheek distention arms to support the soft tissue within the patient's mouth distal to the orbicularis oris muscle.

Abstract: A dental suction device includes a hollow tube having both flexibility and shape retainability. The tube has its both ends connected to a connector and is formed with suction holes. The connector can be connected to a vacuum source. A suction force produced by the vacuum source can thus be applied to the suction holes of the tube through a passage formed in the connector. The connector includes a valve for adjusting the degree of opening of the passage formed in the connector and thus the suction force applied to the suction holes. The valve includes a valve body mounted in the connector and a manual lever for controlling the valve body.

Abstract: A suction device for use in medical dental and veterinary operations comprises a body (X) incorporating a clamp (D) for detachably securing the device to a patient to enable the device to be self-supporting. For use in dental operations the clamp (D) may be designed to be detachably secured to a patient's tooth (A).

Abstract: A mouth prop and tongue retractor apparatus for use in dental procedures. The apparatus includes a handle rotatably mounted within a base. A ball joint on the base fits within a socket in a mouth prop to provide pivotal positional adjustment of the apparatus. An elongated aspirator tube extends through the handle and base, and is coupled to a tongue retractor. A suction aperture on the tongue retractor communicates with the aspirator tube and provides for saliva removal from a patient's mouth. Rotation of the handle provides extension adjustment for the aspirator tube and tongue retractor.

Abstract: A device and methods of use and manufacture are disclosed for controlled diffusion of chemical substances of interest intraorally. The device includes ported structure formed of material that is substantially impermeable to the substance of interest, an inner wall of which defines a compartment communicating through the ports with the exterior of the device. A dispersed layer is formed in the compartment of material having limited permeability, the layer being formed so that contact is maintained with the inner wall across the ports after formation, the ports and the layer thus providing a region of permeability to diffusion of the chemical substance of interest. In use, either the chemical substance of interest or a composition capable of binding itself to the chemical substance of interest is placed in the compartment and the device is positioned in the mouth of a subject where it may remain for extended periods.

Abstract: A dental instrument for removing saliva from a patient's mouth is disclosed that includes a pair of tubes configured to be operatively positioned within the patient's mouth to support a pair of absorbent rolls at the sides of alveolar ridge. One of the tubes terminates at its proximal end in a suction adaptor having a sealing face for contact interface with a suction tube connected to a dental suction device. The proximal end of the other of the tubes intersects the first tube at its mid-length. An absorbent roll supporting perforated stem is removably inserted into the distal end of each of the tubes. Each stem includes a number of apertures in fluid communication with the passageways through the pair of tubes so that suction applied at the suction adapter operates through the apertures to remove fluid absorbed by the absorbent rolls. An adjustable clamping structure is connected to one of the tubes and is mountable under the jaw of the patient to support the instrument.
