<p><P>PROBLEM TO BE SOLVED: To provide a sanitary hand pump spherical body cover for a blood-pressure manometer which is easily removed and exchanged without absolutely deteriorating workability for handling the blood-pressure manometer, its function and performance. <P>SOLUTION: The hand pump spherical body cover is mounted on a pump spherical body by tightly fitting, which is made of an expansible material so as to cover at least a part of the outer wall of the rubber-made hand pump spherical body for the blood-pressure manometer. The material for constituting the hand pump spherical body cover is adopted as an excellently air-permeable diamond-patterned mesh material. A part of the material is opened/closed at a prescribed position from the distal end of the pump spherical body cover. Furthermore, a cover main body is arranged, which is cylindrically formed with an expansible material or formed with a cylindrical seamless fabric. Narrowing means are arranged at both the ends of the cover body. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
