Method and apparatus for dealing with intravenous fluids
First Claim
1. An apparatus for intravenous administration of fluid wherein some fluid may or may not be already contained in a hollow portion of said apparatus, and the apparatus is fed with fluid through at least one opening therein, a normally closed backflow check valve securely received in said opening in fluid-tight fashion, said valve including as a component, a valve member, a receptacle for the introduction of fluid therethrough, a movable means within the receptacle, said receptacle having a first removable cap associated therewith, whereby removal of said cap can enable a non-invasive fluid feeding device to be associated with said receptacle to feed fluid into said apparatus, whereby the valve member is forced away from its sealed, flow-preventing position by movable means contacting against said valve member in response to the forceful introduction of fluid from this device, whereafter the feeding device is removed, the valve member returns to its seated position, and the first cap is replaced on the receptacle.

Abstract
An apparatus is disclosed for intravenous administration of fluid to which fluid may be added according to the process also disclosed, by injecting same, using a syringe, but not a needle, directly into the hollow portion of the apparatus through an opening therein. A normally closed backflow check valve device, having a component thereof acting as a means for receiving the fluid by engagement to the syringe, has been permanently sealed into the opening in the hollow portion of the apparatus. The apparatus is capped by a double luer locking cap, the purpose of which is to protect the opening into the apparatus from contamination. This is accomplished by using a cap structure wherein the cap which will ultimately re-cover the opening is locked into and protected by the cap which initially covers the opening and then discarding this initial cap after the apparatus has been filled.

10. A process for the transfer of biological fluid from an external source into an apparatus for intravenous administration of fluid, wherein there is employed a flexible plastic container including a hollow portion, at least one opening leading into said hollow portion, a normally closed backflow check valve device received in said opening, said valve device including, as a component, a receptacle for the introduction of fluids therethrough, which receptacle can accept fluid by engagement with a non-invasive fluid feeding device, a removable cap associated with said receptacle, and a non-invasive fluid feeding device, and wherein the steps comprise:
-
(a) securely fastening, in a fluid-tight manner, the normally closed backflow check valve device into the opening of the intravenous container; (b) covering the opening of said valve device with the cap structure and locking same into said valve device; (c) filling the fluid feeding device with the fluid to be transferred into the intravenous container; (d) removing the cap structure from the intravenous container; (e) locking the fluid feeding device into the fluid receptacle component of the valve device; (f) injecting a desired amount of fluid from the fluid feeding device through the check valve, non-invasively, into the opening of the intravenous container; (g) unlocking and withdrawing the fluid feeding device; and (h) re-covering the opening of said valve device. - View Dependent Claims (11, 12, 13)
