International Classification:

G01L 7/08

US Classification:

73715, 73714, 73723

Abstract:

The present invention lessens the amount of air entering between mating membranes of a pressure sensor. The pressure sensor of the present invention includes a transducer portion and separate patient or medical fluid transfer portion or dome. The transducer portion is reusable and the dome is disposable. The dome defines a fluid flow chamber that is bounded on one side by a dome membrane. Likewise, the transducer is mounted inside a housing, wherein the housing defines a surface that holds a transducer membrane. The two membranes mate when the dome is fitted onto the transducer housing. The pressure sensor enhances the seal between the mated membranes by creating higher localized contact stresses. The pressure sensor also reduces the amount of gas that permeates from the fluid chamber across the dome membrane and between the interface by making the dome membrane from a material having a low vapor transmission.

US Classification:

607 63

Abstract:

A medical instrument includes a sound card or an internal capability for generating sounds from a digital music or sound file. The medical instrument is one which generates unwanted noise and is constantly in the presence of a patient or an operator, and may be in a home, a clinic, a laboratory, or other intimate setting. For instance, a patient may be typically connected for hours to a hemodialysis machine that has a noisy pump. A blood-plasma volunteer may be hooked to a noisy blood separation machine for a period of time. A laboratory technician may work in close proximity to a sample preparation machine that constantly gurgles and whirrs. In each instance, a sound card and a speaker can generate previously-recorded masking noises that make that the presence and operation of the machine more tolerable.

Abstract:

An adjustable retractor blade and retractor system are disclosed. The retractor blade includes a fixed portion, extendible portion, and means for adjusting the length of the retractor blade. The means for adjusting may include a threaded rod engaging the fixed portion with the extendible portion. In one aspect, the extendible portion includes a plurality of stackable members, with the length of the adjustable blade adjusted by attaching stackable members. In one aspect, the fixed portion includes a plurality of holes, and the extendible portion includes at least one post, the plurality of holes configured to receive the at least one post, with the length of the adjustable blade adjusted by slidably displacing the extendible portion until the at least one post engages with at least one of the plurality of holes. Methods are provided for adjusting the length of a retractor blade.
