Wheatstone Bridge-Type Transducers With Reduced Thermal Shift

View page
US Patent:
46586512, Apr 21, 1987
Filed:
May 13, 1985
Appl. No.:
6/732946
Inventors:
Da Hong Le - La Verne CA
Assignee:
Transamerica DeLaval Inc. - Lawrenceville NJ
International Classification:
G01L 906
US Classification:
73708
Abstract:
Thermal shift in Wheatstone bridge-type transducers is reduced by providing a diaphragm of semiconductor material accepting formation of strain gages therein having a uniform temperature coefficient of resistance therethrough. That diaphragm is supported in a mechanically floating condition, such as by interposing a cushion of compliant material between the diaphragm and a support which is subject to mechanical strains. An amount of unbalance required for balancing the strain gages on the diaphragm is determined. One of these strain gages is provided with a series balance equal to one-half of that determined amount, while an adjacent one of the strain gages is provided with a shunt balance equivalent to one-half of that determined amount. Alternatively, the strain gages are provided with an initial thermal zero shift offset requiring only a shunt balance for compensation, and thermal zero shift is then compensated only with that shunt balance, or the strain gages are provided with an initial thermal zero shift offset requiring only a series balance of compensation, and that thermal zero shift is then compensated with only that series balance.

Catheter Flushing Systems

US Patent:
46246622, Nov 25, 1986
Filed:
Apr 13, 1983
Appl. No.:
6/483207
Inventors:
Da H. Le - Pasadena CA
Assignee:
Transamerica Delaval Inc. - Lawrenceville NJ
International Classification:
A61M 500
F16K 5100
US Classification:
604249
Abstract:
A catheter is flushed intermittently at a flushing flow rate higher than a seeping flow rate with the aid of a valve connected to a supply of flushing liquid. The valve has an operator of an elastic material providing an integral elastic sleeve about a valve stem, for biasing the operator to a rest position before and after manual actuation to a depressed position for a temporary opening of the valve. The operator is protected against accidental depression at all points thereof by a shield completely surrounding and surpassing the operator, so that a human finger has to penetrate into the shield for engagement of the operator prior to depression from its rest position against the bias of the elastic sleeve for an opening of the valve. The seeping flow rate is realized with a capillary passage which may extend along either a valve body or a valve seat in the valve and which is laterally bounded either by the valve seat or the valve body when the valve body is seated in the valve seat. The capillary passage is intermittently opened between continual flushings at the seeping flow rate and is then flushed at the higher flushing flow rate simultaneously with the catheter.

Transducers With Quick Dome Connect Systems

View page
US Patent:
45051577, Mar 19, 1985
Filed:
Aug 5, 1983
Appl. No.:
6/520680
Inventors:
Da Hong Le - Pasadena CA
Assignee:
Transamerica DeLaval Inc. - Lawrenceville NJ
International Classification:
A61B 502
G01L 1900
US Classification:
73756
Abstract:
Methods and apparatus for interconnecting a transducer body with a fluid-receiving transducer dome provide the transducer body with a radial shoulder, where an annular tightening member, rotatable relative to the transducer body, is also provided. An axial bias between the tightening member and the radial shoulder resiliently restrains the tightening member and the transducer body against movement away from each other. A groove for receiving a fastening member projecting either from the tightening member or the dome is provided at the dome or the tightening member. This groove is delimited with a stepped rigid tongue for retaining the fastening member therein. The dome and the transducer body are biased into fluid-tight engagement with the axial bias acting between the radial shoulder and the annular tightening member and acting on the dome through the projecting fastening member and rigid tongue.
