Method of controlling fluid flow with an electronically activated access valve
A method of controlling fluid flow from a fluid source to a patient includes the step of mating a first connector comprising a first body with a first fluid passage therethrough and a conductive element disposed the first body to a second connector comprising a second body with a second fluid passage therethrough and two separated electrical contacts disposed on the body such that the two electrical contacts engage the conductive element when the first and second connectors are mated. The two electrical contacts are electrically coupled to a normally closed, electrically activated valve that is fluidically coupled to the second fluid passage and configured to open only when a circuit is completed through the two electrical contacts.
1. A method of controlling fluid flow from a fluid source to a patient, the method comprising the step of:
mating a first connector comprising a first body with a first fluid passage therethrough and a conductive element disposed on the first body to a second connector comprising a second body with a second fluid passage therethrough and two separated electrical contacts disposed on the body such that the two electrical contacts engage the conductive element when the first and second connectors are mated, the two electrical contacts being electrically coupled to a normally closed, electrically activated valve that is fluidically coupled to the second fluid passage and configured to open only when a circuit is completed through the two electrical contacts.
2. The method of claim 1 , wherein the first and second fluid passages are fluidically coupled when the first and second connectors are mated.
3. The method of claim 1 , wherein the first connector is fluidically coupled to one of the fluid source and the fluid recipient and the second connector is fluidically coupled to the other of the fluid source and the fluid recipient.
4. The method of claim 1 , further comprising the step of:
providing electrical power to the valve such that the valve will open when the first and second connectors are mated.
5. The method of claim 1 , wherein the valve opens automatically when the circuit is completed between the two electrical contacts.
6. The method of claim 5 , wherein the valve opens automatically when the first and second connectors are mated.
7. The method of claim 1 , wherein the valve closes automatically when the first and second connectors are separated.
