| Number | Title | Issue Date |
| 7000483 | Inflatable manometers An inflatable air cell pressure transducer. The air cell has a concavity formed therein. The concavity has two edges, wherein increased pressure within the air cell causes contraction of the concavity moving the two edges closer. ... | 02/21/2006 |
| 6151968 | Wrist band type electronic sphygmomanometer A wrist band type electronic sphygmomanometer including an inflatable wrist band for fastening to the user's wrist, a rubber-bulb operated to inflate the inflatable wrist band, a relief valve controlled to release air from the inflatable wrist band, and a... | 11/28/2000 |
| 5490514 | Medical manometer with flexible fluid collection tube A medical manometer replaces the conventional rigid vertical graduated cylinder with a flexible, graduated tube which is sufficiently pliable that it may be bent to drain the fluid collected during use. This flexibility further obviates the need for a sto... | 02/13/1996 |
| 4282881 | Manometer for infusion apparatus A manometer for measuring the hydrodynamic pressure of fluids parenterally administered to a patient. The manometer includes a transparent housing which has a passageway formed in the housing that accommodates continuous flow of fluid therethrough. A pres... | 08/11/1981 |
| 4146018 | Fluid pressure measuring or testing system and bleed regulation thereof according to schedule A sphygmomanometer system having a cuff, etc, and including both a regulator valve which normally bleeds the cuff pressure down at a substantially constant slow rate, and an exhaust valve which is operable to provide three rates of bleed, to wit nil, fast... | 03/27/1979 |
| 4139000 | Bleedable pressure system for measuring or testing A sphygmomanometric system having a pump for pumping air into a sphygmomanometer cuff connected to the cuff via a regulator valve for bleeding the cuff pressure at a constant rate. The pump has a leak to atmosphere so that the regulator valve can bleed th... | 02/13/1979 |
| 4130114 | Fluid pressure measuring or testing system and bleed regulator valve therefor A sphygmomanometric system having a cuff, etc., and regulator valve for bleeding air out of the sphygmomanometer cuff so that the cuff pressure drops at a substantially constant rate. The valve is in the form of a closed rubber tube having a slit with a p... | 12/19/1978 |
