Title: Nonreturn valves for medical uses
IPC: A61M5/00
Filed: 1968-01-23
Abstract: A valve for use with a medical syringe includes a bored stem 11 constituting part of the fluid path through the valve, a chamber 16 in which the stem is located, and a sock 17 slidingly engaged over the side walls of the stem, the side walls of the sock yielding to permit fluid to pass through the stem into the chamber and being urged into engagement with the stem by pressure fluid on the downstream side of the valve, and the adjacent chamber wall serving to limit sliding movement of the sock. The sock 17 may be rubber or synthetic resin and is extended against ridges at the outlet from the chamber 16 by air flowing from a syringe 22 into the outer concentric tube of a catheter 20 to inflate a balloon by which the catheter may be held in the bladder. To deflate the balloon, the sock is punctured by a needle mounted in the syringe.

Title: 11,12-secoprostaglandins
IPC: C07C323/12
Filed: 1975-06-20
Abstract: 9-Thia-, 9-oxothia- and 9-dioxothia-11,12-secoprostaglandins of the formula II < IMAGE > are prepared, wherein A, R<4>, R<9> and R<10> are defined in Claim 1 and m is 0, 1 or 2. If n = 0, these compounds are obtained by reacting, in optional sequence, di-tert.-butyl malonate with two different appropriate halogeno-esters in order to introduce the two side chains. The reaction product obtained is a disubstituted malonic ester. By heating this ester in the presence of a strong acid, the corresponding substituted decarboxylated malonic acid derivative is obtained. This derivative is then reacted with bromine in the presence of mercury(II) oxide, whereby the carboxyl group is replaced by bromine. The resulting substituted bromo-ester is then reacted with the alkali metal salt of a mercaptan of the formula R<9>SH, and finally the ester group is hydrolysed. To prepare 9-oxothia- and 9-dioxothia-11,12-secoprostaglandins, the 9-thia-11,12-secoprostaglandins are oxidised. The compounds exhibit a prostaglandin-like activity and may be used for the treatment of skin diseases.
