Method for stomach lavage
First Claim
1. A method for providing a closed stomach lavage, comprising the steps of:
- (a) supplying liquid by gravity feed from a flexible reservoir bag having graduations thereon, to an attached feed line having a bore size of about 8-10 mm and a length of about 3-10 feet, the feed line having manual closure means, and being connected to a connection-T;
(b) feeding the liquid from the feed line to a connection-T and to a manually closable, multi-perforated stomach lavage tube attached to the connection-T;
(c) supplying liquid through the lavage tube to the stomach of a patient, and manipulating the lavage tube to remove, by siphoning, foreign matter from the stomach, without the formation of red suction bruises;
(d) siphoning the foreign matter from the stomach lavage tube to a manually closable discharge line connected to the connection-T and then to a discharge bag having an effluent line;
the reservoir bag, feed line, lavage tube, discharge line and discharge bag being disconnectably mounted from each other and the connection-T to form a closed system;
whereby;
i. the feed line is sized to admit by hand metering, about 7-8 liters of liquid from the reservoir bag in about 10-30 minutes for multiple washings of about 300-500 ml each during a period of about 8-25 seconds;
ii. by gravity feed through the lavage tube to a patient;
iii. the volume of liquid admitted from the reservoir bag to the patient being correlated with the graduated scale;
v. material from the stomach of the patient being siphoned through the discharge line and into the discharge bag;
vi. during use, the connection-T can be disconnected to enable removal of material clogging the connection-T;
vii. the closure means on the feed line and lavage tube are open and the discharge line is closed to admit liquid from the reservoir through the feed line, and to the lavage tube, and the closure means on the feed line is closed when the discharge line is open to admit material from the stomach to the discharge line and discharge bag; and
, viii. following use, the lavage parts are discarded.

Abstract
A sanitary, disposable, gastric lavage closed system is disclosed that quickly and effectively flushes material from a patient'"'"'s stomach. The system includes an elevated, plastic reservoir bag connected through a feed line having a specified bore range, to a T-connection. A gastric tube is fitted to the T-connection and is adapted for insertion into the patient'"'"'s stomach. A fixed volume of liquid from the reservoir bag is admitted to the patient by pump or by hand control of the feed line over a short, measured period of time.
Material in the patient'"'"'s stomach is then quickly removed into a disposable container that forms a closed system with the rest of the components.
An injection syringe may be employed to inject treatment materials into the stomach, remove test samples, and maintain the system free of clogged material.
An attachment for colonic irrigation and enemas may be employed to replace and/or by-pass the gastric tube.
