摘要:
A dispensing closure assembly includes an outer closure body having an upper tubular portion which can function as a mouthpiece for users. The closure assembly includes a flexible valve member mounted within the tubular portion of the closure body for dispensing of liquids or like contents by either the application of suction by a consumer, or by squeezing the associated container. By the provision of a liquid seal lip which coacts with an inside surface of the flexible valve member, the closure assembly can be configured to facilitate convenient use by consumers, while avoiding undesirable leakage attendant to normal handling during use.
摘要:
A surgical instrument for at least partial occlusion of the uterus blood vessels comprising two opposing jaws with scissor-type handles and a latching mechanism.Each jaw has a straight member 1 and a straight member 2 connected with an angle 30-45 degrees. Each said member 1 has a tubular cover. Each member 2 is integrated with the scissor-type handle. Each jaw has an inner side and an outer side. The jaws are made movable relative to each other in order to at least partially occlude the uterus blood vessels by the opposite sides of the covers on the inner sides of the members 1. The latching mechanism is made to retain the jaws in the working position over a needed period of time and release the jaws when the need for occlusion is over.Each cover has an inner cavity open from one end for receiving and retaining the member 1 of said jaw. The thickness of each said cover on the inner side of the member 1 is 8-12 mm, the width of said cover is 10-30 mm, the length of said cover is 50-60 mm, and said cover is made of soft plastic, silicon, fabric, gauze or non woven material.
摘要:
A method for performing a cesarean section includes the occlusion of uterine arteries using an atraumatic occlusion instrument, for example, an atraumatic clamp, after pulling the uterus from the pelvic cavity and placing it on the patient abdomen, The method significantly reduces blood loss in patients. An atraumatic occlusion clamp has disposable covers made of gauze.

In one embodiment, a vortex tube has a gas inlet port, a cold gas outlet port and a hot gas outlet port. A thermoelectric potential generator having hot gas inlet port coupled to the hot gas outlet port of the vortex tube, a cold gas inlet port coupled to the cold gas outlet port of the vortex tube, and a thermoelectric element coupled in heat conducting relationship between the cold gas inlet port and the hot gas inlet port to promote the flow of heat/cold through the thermoelectric element from the hot gas flowing into the hot gas inlet port to the cold gas flowing through the cold gas inlet port. In another, a compressed gas source, a thermoelectric element having first and second sides, and an expansion nozzle are coupled in series. The expansion nozzle is coupled between the compressed gas source and the first side. The thermoelectric element includes an electrical output port.

A surgical instrument for at least partially occlusion of the uterus blood vessels during a cesarean section comprising two jaws movable relative to each other to at least partially occlude the uterus blood vessels, latching mechanism to retain the jaws the in the working position over needed period of time and release the jaws when the need for occlusion is over,a disposable tubular cover on the end member of each jaw, said end member of a jaw is connected with the other member of the jaw with an angle 25-45 degrees, preferred angle is 30-45 degrees, said cover has an inner cavity open from one end for receiving and retaining the jaw, the thickness of the side of the cover to be engaged with the blood vessels is 3-15 mm, preferably, 8-12 mm, the width of said cover is 10-30 mm, the length of said cover is 50-60 mm, and said cover made of gauze or fabric.
摘要:
An aerosol spray can is provided. The aerosol spray can includes but is not limited to a housing, an initial amount of a chemical within the housing in both liquid and gaseous states, a valve assembly attached to the housing, an extension tube connected with the valve assembly, and a flotation device connected with the extension tube. The chemical in a liquid state forms a top surface above which there is the chemical in a gaseous state. The extension tube is connected with the valve assembly at a first end and extends into the housing at a second end. The second end of the extension tube forms an opening. The flotation device floats on the chemical in a liquid state.
摘要:
An apparatus and method for detecting a surgical implement retained within a surgically exposed human body cavity, include tagging means adapted to be attached to a surgical implement insertable within a human body cavity and including means for receiving an electromagnetic signal and converting it into electric current (pulses); and means to conduct said current (pulses) to the internal human (or an animal) body where said medical product is used; and means to transmit said electromagnetic signal; and detecting means including reception means for receiving a signal from a tagging means, detector means connected to the reception means for sensing a signal received from a tagging means. The envelope of the induced RF wave is demodulated, thus allowing the voltage at output to vary at a significantly lower frequency. In the event such pulses are sensed, a sensory alert is actuated and corrective action taken.
