A combination artificial airway device and esophageal obturator (10) includes a esophageal cuff (16) and supraglottic cuff (14) that are inflated in a sequence to provide quick isolation of the esophagus relative to the tracheal air passage. The supraglottic cuff is asymmetrical in shape with a wedge like or cone like shape that is ergonomically shaped for providing less trauma to the pharyngeal tissues. A pressure indicator (25) surrounds a pilot balloon (28) for continuous monitoring of the internal pressure within the cuffs (14&16).

Methods and systems for reverse-circulation cementing in subterranean formations are provided. An example of a method is a method of cementing casing in a subterranean well bore, comprising inserting a casing into the well bore, the casing comprising a casing shoe; equipping the casing with a well head, and a casing inner diameter pressure indicator; flowing an equilibrium fluid into the well bore; flowing a cement composition into the well bore after the equilibrium fluid; determining from the well-bore pressure indicator when the well bore pressure has reached a desired value; discontinuing the flow of cement composition into the well bore upon determining that the well bore pressure has reached a desired value; and permitting the cement composition to set in the subterranean formation. Examples of systems include systems for cementing casing in a well bore.

The present invention provides a device for non-invasive monitoring thermal stress of a user. The device is capable of monitoring the internal body temperature and changes in the internal body temperature of a user. Also, the device is capable of alerting a user when the user is in danger of thermal stress.

A tire pressure indicator for coupling with a valve stem of a tire. The tire pressure indicator provides a first visual indication in the event that the tire pressure is below a first threshold limit and a second visual indication if the tire pressure is above a second threshold limit. The pressure indicator includes a dome shaped indicator and a dome shaped cover that is mounted over the indicator. The cover includes a plurality wedge shaped transparent viewing windows extending from near the top of the dome. The transparent viewing windows are separated by opaque portions. The indicator has a plurality of alternating wedge shaped areas of first and second colors extending from near the top of the dome to the lower peripheral edge of the indicator. The rotation of the indicator is related to the tire pressure. In one orientation of the indicator that occurs when the tire pressure is below a first predetermined limit, the first color is visible through the transparent viewing windows of the outer dome. In a second orientation of the inner dome that exists when the tire pressure is above a second predetermined limit, the second color is visible through the viewing windows of the outer dome.

An air pressure gauge assembly is mounted to the valve stem of a tire or integrated into a wheel rim for continuous monitoring of the tire inflation pressure. The gauge assembly includes a check valve functionally coupled to the valve stem so that the check valve provides the common function of the valve stem, including allowing for inflation and deflation. The assembly also includes a pressure sensor coupled to a visually perceptible pressure indicator on a dial face.

A compact, robust, and inexpensive magnetically coupled pressure gauge includes a spiral-faced or helical bellows coupled for rotating a magnetic field source (permanent magnet) within a pressure vessel the orientation of which is externally sensed and correlated to pressure within the pressure vessel. Mechanisms of extraneous magnetic field compensation are discussed Applications contemplated include measuring pressure in pressure vessels and pressure of pneumatic vehicle tires without breaching the integrity of the particular pressurized vessels. Embodiments included a visual, manual tire pressure monitoring system.

Disclosed are systems and methods for preserving wine in a decanter. The system comprises a stopper adapted for engaging and airtight sealing the mouth of the decanter; the stopper comprises a valve assembly operable to draw and maintain a pressure differential within the decanter and a pressure indicator operable to indicate vacuum pressure within the vessel. The system further comprises a pump operable to engage the valve assembly and to draw gas from within the decanter to an external atmosphere.

The invention discloses a structure of a double-balloon laryngeal mask airway for gastroenterological endoscope examination. The double-balloon laryngeal mask airway comprises a ball balloon, a cover balloon, an air vent pipe, an air source joint, inflation tubes, a plug and pressure indicators, wherein the ball balloon is ball-shaped; the cover balloon is oval-shaped; the air vent pipe sequentially passes through the ball balloon and the cover balloon; a front-end opening of the air vent pipe is wrapped by the ball balloon to form a ring-shaped balloon buffering opening, the middle part of air vent pipe is connected with the cover balloon to form a back balloon, and an opening in the back end of the air vent pipe is connected with the plug; a bypass channel opening in a side wall of the air vent pipe is connected with the air source joint; and the side wall or the rear part of the air vent pipe is connected with the inflation tubes communicated with the pressure indicators. A gastroenterological endoscope enters the esophagus and the stomach or an intestine of a human body through independent cavity channels at the inner part of the air vent pipe; and a supporting table and a blocking piece are arranged at an air vent opening in the middle part of a laryngeal mask, and the air vent opening is communicated with a trachea of the human body to form a closed respiration channel. Through the adoption of the double-balloon laryngeal mask airway, gastroenterological endoscope examination can be conducted while a patient has an anesthesia operation or is rescued, and reflux content in the stomach can be prevented from entering the trachea, so as to reduce pain of the patient and improve the safety of the operation.

Pressure gauges used to indicate the pressure of the air being supplied to a patient during resuscitation should be able to indicate the pressure quickly and simply. In the present disclosure, a medical apparatus includes an apparatus body defining a fluid cavity that is fluidly connected to an expandable pressure chamber of a pressure gauge. The pressure chamber, a battery and at least one pressure indicator are, at least partially, positioned within a gauge body of the pressure gauge. An electrical conductor is moveable with the expandable pressure chamber among a plurality of positions and with respect to the gauge body. When the electrical conductor is in a first position, the battery is out of electrical connection with the at least one pressure indicator. When in the second position, the electrical conductor electrically connects the battery with the at least one pressure indicator.

A multiple-function valve cap is disclosed for mounting on a valve stem of a tire for indicating a safe pressure condition or a low pressure warning. The multiple-function valve cap includes a pressure indicator assembly having a piston including a safe pressure indicator, and an internal bore. A warning indicator is seated within the internal bore of the piston. A biasing spring is fitted between the low pressure warning indicator and the safe pressure indicator, and acts to urge them apart, such that the warning indicator is displayed when low pressure is applied to the piston. When a safe level of air pressure is applied to the piston, the piston is moved against the force of the biasing spring to surround the warning indicator, and the safe pressure indicator is displayed.
