Abstract
A method is described for treatment of aphthous ulcers or canker sores whereby brief high-pressure vacuum is administered to the aphthous ulcer, resulting in swelling and minor hemorrhage, with immediate relief of pain and hastening of healing of the ulcer.
Claims
1. A method for treating ulcers of the oral mucosa accomplished by creating a high vacuum pressure (between minus 0.5 and minus 1.0 atmospheres of vacuum pressure) using a hand-held device comprising a pump mechanism and applying the suction using a cup interface from the device to the oral mucosa such that vacuum is applied to part of all of the ulcer surface.
2. A method for treating ulcers of the oral mucosa of claim 1 where the vacuum chamber is at least 2 cubic centimeters in volume.
3. A method for treating ulcers of the oral mucosa of claim 1 where the treatment is applied for less than 5 seconds.
4. A method for treating ulcers of the oral mucosa of claim 1 where mild to moderate soft tissue swelling is apparent immediately after termination of the treatment application.
5. A method for treating ulcers of the oral mucosa of claim 1 where petechial hemorrhage of the ulcer surface results from the treatment.
6. A method for treating ulcers of the oral mucosa of claim 1 where extraction of a small amount (less than a few drops) of frank blood is achieved.
Description
BRIEF DESCRIPTION OF THE DRAWINGS
[0020] FIG. 1 is a cutaway longitudinal perspective of the suction or vacuum device, comprising a syringe chamber 1, a piston 2, a spring 3, a tab on the proximal end of the syringe 4, stops 5 within the piston chamber to prevent disengagement of the plunger, and a cup 6 at the distal tip of the syringe that is used to engage the oral mucosa surrounding the aphthous ulcer.
[0021] FIG. 2 is also a cutaway longitudinal perspective of the suction or vacuum device, with a larger cup 6 at its distal tip.
[0022] FIG. 3 is a similar longitudinal cutaway view of the suction or vacuum device, with a straight extension 7 from the syringe chamber 1 to the distal tip 6.
[0023] FIG. 4 is a cutaway longitudinal view of the suction or vacuum device with a curved extension 7 from the syringe chamber 1 to the cup 6.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0024] Referring to the drawing figures, like reference numerals designate identical or corresponding elements throughout the several figures. The singular forms a, an, and the include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to a syringe includes reference to one or more of such syringes, and reference to the cup includes reference to one or more of such cups.
[0025] To apply the treatment for aphthous ulcers disclosed herein, a suction apparatus like the one depicted in FIG. 1 is used. The suction apparatus has a proximal end that is held in the hand of the user, and a distal end with a cup whose rim in one embodiment encompasses the peripheral margin of the ulcer. In one exemplary embodiment of the suction apparatus depicted in FIG. 1, the piston 2 is depressed while holding the tabs 4 on the syringe body to fully purge the syringe chamber 1, and then the cup 6 is pressed into contact with the oral mucosa so that the rim of the cup surrounds the ulcer in its entirety, or nearly so, in an air-tight seal. Alternatively, for large ulcers, to minimize discomfort, subtotal sections of the ulcer can be treated, with multiple overlapping treatments applied to treat the entire ulcer. The piston 2 is then released, and the spring 3 pushes the piston out of the back or proximal end of the syringe chamber 1 until it hits stops 5 on the syringe and can't move any further proximally, thereby creating a vacuum or suction within the syringe 1 and cup 6. In this example, the cup 6 has a small diameter (e.g., less than 5 mm). As depicted in the figures, the spring apparatus enables the user to generate suction force by compressing the piston 2 rather than extracting it from the syringe, thereby permitting single hand use. Sufficient suction is administered such that a small amount of blood is extracted from the ulcer to coat the surface of the ulcer where the oral mucosa has broken down. After a brief time, e.g., less than 5 seconds of suction, the user depresses the piston 2 again and releases the vacuum, and removes the suction device. When suction is released and the suction device removed mild to moderate swelling of the treated tissues is apparent immediately, and a small amount of hemorrhage may be apparent as petechial or microscopic spots of hemorrhage within the ulcer, or even a small amount (less than one drop) of frank hemorrhage in the ulcer, or in the cup 6 of the suction device. That sequence comprises the treatment method. Note that in this preferred embodiment the vacuum is generated using a syringe chamber and piston, but that other methods of generating suction such as for example a roller pump or Venturi effect are envisioned and incorporated herein.
[0026] FIG. 2 shows a different embodiment of the suction device, wherein said suction device has a large (e.g., less than 2 cm) cup 6 at its distal end.
[0027] FIG. 3 shows yet another embodiment of the suction device, wherein said device has a straight extension tube component 7 between the cup 6 and syringe chamber 1.
[0028] FIG. 4 show still another embodiment of the suction device, wherein said device has a curved extension tube component 7 between the cup 6 and syringe chamber 1.
