An intravenous set with an automatic stopping mechanism in the drip chamber is provided. A top portion of the drip chamber may have a cap with a sharp tooth for puncturing a container or bottle. A lower portion of the drip chamber may be connected to a joint or stem that is connected to a flexible tube ending in a valve to be connected to a catheter. The drip chamber may contain a stopper for automatic control of fluid flow from the drip chamber. The stopper may include a lower part or diaphragm, a middle part or stem and an upper part. The stem and diaphragm may be connected by a stud, which is a part of the diaphragm. The stopper falls as the fluid flows through an exit of the drip chamber and closes the exit of the drip chamber when the fluid in the drip chamber is finished. |
