Embodiment Construction

[0010] first reference figure 1 , monitoring instrument 10 is shown connected to blood pressure cuff 16 through pneumatic conduit sections 12 and 14 . The inflatable cuff 16 is typically wrapped around the patient's upper arm and held securely by overlapping hook and loop fasteners. A relatively short section 14 of small bore flexible catheter is secured to a cuff 16 and provides air to inflate a balloon inside the cuff. The conduit section 14 terminates in a pneumatic connector 20 .

[0011] Furthermore, a generally longer section 12 of the catheter is connected at one end to the inflation port 8 of the monitoring instrument 10 . The conduit section 12 terminates in a pneumatic connector 40 . The monitoring instrument shown in this example is to monitor various bodily functions (e.g. patient's ECG, heart rate, CO 2 and other functions) instruments. The patient's most recent blood pressure measurement is shown on the second line of the monitor display 6, which in this exa...

Abstract

A connector apparatus for small-bore medical tubing includes a male connector (20) with a dome (22) which fits into a mating cavity (42) of a female connector (40) when the two connectors are coupled together. A fluid channel extends through the connectors, the dome, and into the cavity to form a continuous fluid passageway when the connectors are coupled together. The dome is compressed into the cavity to form a fluid-tight connection when the connectors are coupled together. Each connector has a coupling structure which mates with the other to compress the connectors together when fully engaged. The connectors are engaged by inserting the dome of one of the connectors into the cavity of the other connector, then rotating the connectors to fully couple them together.

Description

technical field [0001] The present invention relates to a fluid connection for a medical device, and more particularly to a pneumatic connector for a small bore catheter that guides a fluid, such as a liquid or a gas. Background technique [0002] Many medical devices use pneumatic catheters to direct fluids, such as liquids or gases, to or from a patient. The saline bag can be attached to the IV needle to administer the drug compound to the patient. Tubing is needed to connect the patient's mask to an instrument that measures the patient's breathing gas or supplies oxygen to the patient. Another example that requires pneumatic catheters is non-invasive blood pressure monitoring. For periodic monitoring at the bedside, an inflatable pressure cuff is wrapped around the patient's arm. The pressure cuff is connected to a non-invasive blood pressure monitor via a pneumatic catheter. Periodically, the blood pressure monitor will inflate the cuff around the patient's arm, then...
