Abstract

In a trumpet valve style manifold it is possible to get material that is suctioned through the valve, trapped on the trumpet valve stem, or between the valve stem and manifold bore. These are several ideas that describe features in a trumpet valve style manifold that will aid in the removal of trapped material, or features that will minimize the potential for trapped material.

Improved Flowpath Clearing with a Trumpet Style Valve

Summary

Problem statement:

In a trumpet valve style manifold it is possible to get material that is suctioned through the valve, trapped on the trumpet valve stem, or between the valve stem and manifold bore.

These are several ideas that describe features in a trumpet valve style manifold that will aid in the removal of trapped material, or features that will minimize the potential for trapped material.

Description

One solution, the valve could be configured to have serrated "teeth" along the valve stem which would allow the "trapped" material to be freed by cycling the valve up and down, so that the teeth cut through and/or displace the material.

Another solution is to add a "blade" to the valve by coring the valve to accept a blade rod, and adding a slot to both valve and blade rod to accept the blade. A spring can be added either proximal or distal to the blade rod

A 2-stage operation for valve opening is created with the following steps


1. Resting state
2. Blade moves to distal position
3. Valve moves to open position allowing suction
4. Valve moves to closed position
5. Blade moves to proximal position, cutting any trapped material, allowing removal by suction

Another solution is to attach a cylindrical blade to the stem of the trumpet valve that rotates as tissue/fluids pass through the valve channel. This rotation would morcelate any large clumps of tissue. The cylindrical blade could be stationary or travel up and down the stem of the trumpet valve.

Another solution is to implement a "chomper" valve design, where up...
