Patent number: 11865293Abstract: A body-fluid-and-medication leak-proof and closed medical connector has a first connecting assembly and a second connecting assembly. The first connecting assembly has a first sleeve and a first resilient valve. The first resilient valve tends to seal a first opening of the first sleeve. The second connecting assembly has a second sleeve and a second resilient valve. The second resilient valve tends to seal a second opening of the second sleeve. The two resilient valves can avoid leakage of the medication remaining in an injector and a vial, or remaining in a fluid infusion tube and a catheter. The two resilient valves also can seal in two directions to avoid leakage during connecting or separating the two connecting assemblies after supplying medication. Therefore, the transfer of the medication is more hygienic and safe, and the waste of medical resources is effectively reduced.Type: GrantFiled: November 20, 2020Date of Patent: January 9, 2024Inventor: Hsi-Chin Tsai

Patent number: 6279608Abstract: The invention relates to a connection for connecting a measuring device (6) to a gas pipe, comprising: a connecting element (1) for arranging in the gas pipe which divides the gas pipe into a first and a second piece (2, 3); a connecting plug (4) which can be coupled to the connecting element and which is connected to the measuring device by means of a measuring line (5), wherein the connecting element comprises a valve which is actuable by the connecting plug and which normally mutually connects the first and the second piece of the gas pipe and which, when the connecting plug is coupled to the connecting element, connects the first piece of the gas pipe to the measuring line and closes the second piece of the gas pipe. As a result of these measures the valve is operated by the connecting plug, so that opening and closing of taps is no longer necessary. The operation of such a connection is therefor greatly simplified.Type: GrantFiled: September 7, 2000Date of Patent: August 28, 2001Assignee: Kamstrup B.V.Inventor: Jacobus F. A. Langeveld

Patent number: 6257550Abstract: A drain valve adapter is for use with a hose and a drain valve mounted to a container, wherein the drain valve of the container defines a passageway for aqueous solution. The drain valve adapter comprises a tubular body having a mating member and a plunger member which are in fluid communication with each other, the plunger member being configured to be disposed inside the drain valve along the passageway. The drain valve further comprises a ring cap defining a through hole and being disposed in surrounding relation to the tubular body for releasably engaging the drain valve. The plunger member has at least one prong extending therefrom to force open a drain plug blocking the passageway of the drain valve. Preferably, the plunger member has a plurality of prongs extending therefrom. The plurality of prongs define spaces therebetween to allow free flow of the aqueous solution in the container. The mating member has a threaded outer surface for engaging with a female coupler of a standard garden hose.Type: GrantFiled: April 6, 2000Date of Patent: July 10, 2001Assignee: Intex Recreation Corp.Inventors: Richard A.
