Abstract

Disclosed is a system for administering medication through the nasal passage of a patient into the patient'"'"'s stomach. The system includes a connector having a body member with the passageway therein and extending between open ends in the body member. At each of these ends is a series of flanges with tapered edges. One of these ends is inserted into a tube extending through a patient'"'"'s nose and into the patient'"'"'s stomach. The other end is connected to either a suction or feeding pump at the appropriate time by a nurse. Within the body member is a port through which medication is introduced. A valve at the port either opens or closes the passageway as required.

Claims

1. In administering medication to a patient,

(1) inserting through a nostril of a patient a tube that has a first end extending into the stomach of the patient and a second end extending from the nostril,

(2) inserting into the second end a connector including,

(a) a port for receiving medication from a gastric syringe, and

(b) a manually operable valve which controls the flow of medication introduced by the syringe into the port, so that when the valve is open medication flow through the tube into the stomach of the patient, and

(3) with the valve open, inserting a gastric syringe containing medication into the port and feeding the medication from the syringe into the port, through the open valve and tube into the stomach of the patient.

2. In administering medication to a patient in accordance with claim 1,

wherein the port is surrounded by a barrel that is tapered inwardly to receive a tapered end of the gastric syringe.

3. In administering medication to a patient in accordance with claim 2,

wherein an end of the connector is free and has an internal taper that allows a tapered end of a feeding pump to be inserted into a held securely in the connector.

4. In administering medication to a patient in accordance with claim 3, the connector has opposed ends with each end having a series of different sized tapered flanges that are adapted to receive tubes of different diameters.

5. A medical connector adapted to be removably attached to the open end of one of several different flexible tubes of varying diameters comprising,

a body member having a passageway therein extending between opposed open ends in the body member,

each of said open ends having thereat flanges with tapered edges so that either end of the body member may be inserted into an open end of a selected tube,

a port between the open ends of the body member which is in communication with the passageway, said port being enlarged and said passageway being enlarged to allow medication that is granular to flow through the connector,

a funnel member at the port which is adapted to receive the delivery end of a gastric syringe an direct medication flowing from said delivery end through the port and into the passageway, the funnel member including a barrel section having an inwardly tapered portion for receiving the delivery end of the syringe which is tapered and fits snug within said tapered portion of the barrel section, and

valve means for the port for opening and closing said port.
