Abstract

A needleless fluid delivery device can be coupled to a valve to deliver fluid to a patient. When the device is withdrawn from the valve, the fluid inside the valve can leak out of the valve. This problem can be addressed with an anti-leak valve. The anti-leak valve can include a housing having a reception lumen and a delivery lumen that is transverse to the reception lumen. A guide bush is positioned in the reception lumen, and a silicon tube bears outwardly against the delivery lumen. When the device is inserted into the reception lumen, the device displaces the guide bush and compresses the silicon tube. This compression fluidly connects a hole in the guide bush to the delivery lumen, which facilitates delivery of the fluid. When the device is removed, the silicon tube seals the delivery lumen and restricts fluid from leaking out of the valve.
