    • A wart removal device and method of using same are disclosed. The device has a handle and a pad affixed to the handle. The pad has a base and a plurality of tines. Each tine preferably has a height that is not less than approximately twice its width and that is more preferably not less than approximately three times its width. The tine height is preferably less than approximately 0.1 inch and is more preferably less than approximately 0.05 inch. The pad has a width that is preferably not greater than approximately null inch and a length that is preferably not less than approximately twice its width. The pad has a width that is more preferably not greater than approximately null inch and a length that is more preferably not less than approximately null inch. Each tine is preferably sharpened so that opposing sides form a point at an upper edge with the opposing sides forming an angle that is substantially within a range of from approximately 20null to approximately 40null. In operation, the device is raked against wart tissue to create a plurality of incisions in the wart tissue. The sharpness and cutting depth of the device are designed to create a plurality of incisions without causing noticeable bleeding. The device may be used in combination with a medicament, such as pyruvic acid, to improve the effectiveness of the medicament. The device and medicament may be provided as a kit, such as by prescription, for use by a patient in a non-clinical setting.
    • 公开了一种疣去除装置及其使用方法。 该装置具有固定在手柄上的手柄和垫。 垫具有基部和多个尖齿。 每个齿优选具有不小于其宽度的大约两倍的高度,并且更优选地不小于其宽度的大约三倍。 齿高度优选小于约0.1英寸,更优选小于约0.05英寸。 垫的宽度优选不大于约1/4英寸,并且长度优选不小于其宽度的大约两倍。 垫具有更优选不大于约1/8英寸的宽度,更优选不小于约1/2英寸的长度。 每个齿优选地被磨尖,使得相对侧在上边缘形成点,相对的侧面形成基本上在大约20°至大约40°的范围内的角度。 在操作中,将装置倾斜到疣组织以在疣组织中产生多个切口。 设备的清晰度和切割深度被设计成产生多个切口而不引起明显的出血。 该装置可以与药物如丙酮酸组合使用,以提高药物的有效性。 该装置和药物可以作为试剂盒提供,例如通过处方,供非临床环境中的患者使用。

    • A device for administering a quantity of liquid cooling agent, contained in an aerosol container provided with a normally closed valve has an operating device for temporarily opening the valve. The positioning device positions at least a part of an administering element so that the cooling agent leaving the valve can reach the administering element. The cooling agent leaving the valve reaches that part of the administering element which comes into contact with a wart to be frozen, so that it is used effectively. According to a first preferred embodiment the positioning device has a chamber which is connects to the valve and into which the cooling agent is carried when the valve is operated. The chamber is adapted to receive of at least a part of the administering element.
    • 包含在设置有常闭阀的气溶胶容器中的一定量的液体冷却剂的装置具有临时打开阀的操作装置。 定位装置定位给药元件的至少一部分,使得离开阀的冷却剂可以到达给药元件。 离开阀的冷却剂到达与冷冻疣接触的给药元件的那部分,从而有效地使用。 根据第一优选实施例,定位装置具有连接到阀的腔室,当阀被操作时,该腔室被承载在该腔室中。 腔室适于接收给药元件的至少一部分。

    • A cryogenic probe is disclosed comprising a barrel having a plunger mechanism movably mounted therein and having a valve on the lower end thereof. The valve normally closes the lower end of the barrel but the plunger may be moved relative to the barrel to permit cryogenic liquid such as liquid nitrogen to by-pass the valve and to move upwardly into the interior of the barrel. The valve has a tip portion at the lower end thereof. The barrel is removably positioned in a guard so that the tip portion extends outwardly through the bottom of the guard and so that the upper end of the plunger is exposed above the guard. The tip portion has a lower end portion which is extremely thin so that the cryogenic liquid will be positioned closely adjacent the skin but not in actual contact therewith when the tip portion is placed into contact with the patient's skin. The method of charging the device is disclosed as is the method of using the same.
    • 公开了一种低温探针,其包括具有可移动地安装在其中且在其下端具有阀的柱塞机构的筒体。 阀通常关闭桶的下端,但是柱塞可以相对于筒移动,以允许诸如液氮的低温液体绕过阀并向上移动到桶的内部。 该阀在其下端具有尖端部分。 枪管可拆卸地定位在防护装置中,使得尖端部分向外延伸穿过护罩的底部,并且使得柱塞的上端暴露在护罩的上方。 尖端部分具有非常薄的下端部,使得当尖端部分与患者皮肤接触时,低温液体将被定位成紧邻皮肤而不是实际接触。 公开了对该装置进行充电的方法,其使用方法也是如此。
