One-piece unitary occluder

Abstract

A one-piece unitary occluder is disclosed which is utilized with a fluid administration set to occlude a portion of a tube assembly which is interconnected between a source of fluid and a patient. The one-piece unitary occluder has a body with a pair of openings which are diametrically aligned with an aperture to allow fluid flow therethrough; however, once activated, the openings are misaligned relative to the aperture to occlude a portion of the tubing to prevent fluid free-flow if the tube assembly becomes disassociated from the pump.

I claim:  
     
       1. A one-piece unitary occluder comprising: 
       a pair of end portions at least partially overlapping, each end portion having an opening, a body including at least one hook portion proximate one of said openings for engagement with the other opening, said body further including an aperture through said body.  
     
     
       2. A one-piece unitary occluder according to  claim 1 , wherein said one-piece unitary occluder further comprises a generally cylindrical shape. 
     
     
       3. A one-piece unitary occluder according to  claim 1 , wherein at least one of said end portions further comprises a generally V-shaped portion. 
     
     
       4. A one-piece unitary occluder according to  claim 1 , wherein said at least one hook further comprises a pair of hooks. 
     
     
       5. A one-piece unitary occluder according to  claim 1 , wherein said one-piece unitary occluder is formed from a plastic material. 
     
     
       6. A one-piece unitary occluder according to  claim 1 , wherein said body further includes a shoulder disposed about said aperture. 
     
     
       7. A one-piece unitary occluder comprising: 
       a pair of ends at least partially overlapping, each end having an opening therethrough, said body further including an aperture;  
       means for retaining said openings in an aligned configuration relative to said aperture; and  
       means for urging said openings into misalignment relative to said aperture.  
     
     
       8. A one-piece unitary occluder according to  claim 7 , wherein said means for retaining includes at least one hook portion disposed proximate one end for engagement with the other end. 
     
     
       9. A one-piece unitary occluder according to  claim 8 , wherein said at least one hook comprises two hooks oppositely disposed about the one opening. 
     
     
       10. A one-piece unitary occluder according to  claim 8 , wherein said means for urging comprises said body being formed from an elastic material. 
     
     
       11. A one-piece unitary occluder comprising: 
       a pair of ends at least partially overlapping, each end having an opening therethrough; and  
       an aperture formed therethrough;  
       whereby said ends are movable between an aligned position having said openings aligned with said aperture and a misaligned position with said openings misaligned relative to said aperture.  
     
     
       12. A fluid administration system for delivering fluid from a fluid source to a patient, said fluid administration system comprising: 
       a pump having a rotor and a recess formed adjacent the rotor, said pump further including a cover pivotably attached over the recess;  
       a tube fitted about the rotor; and  
       a one-piece unitary occluder fitted within the recess with a portion extending outwardly therefrom.  
     
     
       13. A fluid administration system according to  claim 12 , wherein said one-piece unitary occluder further comprises a generally cylindrical shape. 
     
     
       14. A fluid administration system according to  claim 12 , wherein at least one of said end portions further comprises a generally V-shaped portion. 
     
     
       15. A fluid administration system according to  claim 12 , wherein said at least one hook further comprises a pair of hooks. 
     
     
       16. A fluid administration system according to  claim 12 , wherein said one-piece unitary occluder is formed from a plastic material. 
     
     
       17. A fluid administration system according to  claim 12 , wherein said one-piece unitary occluder further includes a shoulder disposed about said aperture.
