Problems solved by technology

The disadvantage of the blocking system shown in the '978 patent is that it is rather bulky
Also, when the trigger is placed in the lock open position, the module will not load properly into the pump as the pump door will not close

Embodiment Construction

[0056] The drawings will be described below with reference to reference numerals in the drawings in order to enable those skilled in the art to practice the present invention. The drawings and descriptions are examples of aspects of the invention and do not narrow the scope of the appended claims.

[0057] refer to figure 1 , which shows a perspective view of an occluder, generally indicated at 10 , which is arranged along the line 14 of the infusion set 14 . For clarity, a shorter section of tubing is shown. It should be understood, however, that tubing 14 is typically connected at one end to a solution reservoir and at the opposite end to an infusion adapter. The infusion adapter may be an adapter for connection with a stoma tube for enteral feeding or an IV needle for parenteral solutions.

[0058] figure 1 The occluder 10 is shown in a first closed or blocked position. The occluder 10 includes a body 18 and a plunger 22 . The body 18 includes a void in which the plun...

Abstract

An improved safety occluder and method of use provides an occluder for an infusion set having a first, occluding position, a second, non-occluding position which returns to the first, occluding position when the occluder's plunger is released, and a third, non-occluding position which retains the plunger in a configuration which allows fluid flow through the infusion set. The occluder may also include a locking mechanism to prevent accidental movement of the plunger out of the first, occluding position.

Description

technical field [0001] The present invention relates to a device and method for selectively preventing free flow during administration of enteral or parenteral solutions through an infusion line. In particular, the present invention relates to an occluder / valve and method for use in an infusion set or the like, wherein the occluder / valve prevents undesired free-flowing solution from passing through the infusion set while allowing a healthcare professional to place the infusion set in free-flow state to facilitate rapid delivery of fluid to the patient. Background technique [0002] The use of infusion sets to administer solutions to patients is well known in the medical arts. The infusion set is for enteral and parenteral use. Enteral feeding pumps are used to provide nutrition and medication to patients when they cannot eat normally for some reason. Parenteral (intravenous) solutions are given to patients to ensure adequate hydration and to provide needed nutrients, mine...
