Abstract

Abstract A catheter device is described with a safety needle guard that covers and protects the needle after use of the device. The device includes a semi-tubular needle housing containing a flash chamber with a hollow needle extending from the distal end of the flash chamber. A tubular needle guard concentrically fits and slides within the needle housing. The needle guard has a longitudinal slot through which the mounting base of the flash chamber passes as the guard slides within the housing. The top of the semi-tubular housing is open so that a user may access the top of the tubular needle guard with a finger to urge the needle guard to an extended position from the distal end of the housing and in a surrounding position about the needle. The proximal end or hose of the needle guard detaches for the needle housing and has a luer fitting for an infusion set. The catheter hub contains a lever capable of occluding the catheter to inhibit fluid flow.

Claims Analysis

Total Claims: 10

Claim 1

Independent Claim 56 words

A catheter assembly comprising: a catheter attached to a catheter hub; a hollow needle extending into said catheter and removable from said catheter; and occludable means on hub for preventing fluid flow through said catheter, wherein said occludable means includes a lever mounted on and pivotable about said catheter hub and capable of occluding said catheter.

Claim 2

Dependent Claim 56 words

Claim 3

Dependent Claim 21 words

The catheter assembly of claim 1, further including means for inserting said lever through said catheter hub and into said catheter.

Claim 4

Dependent Claim 15 words

The catheter assembly claim 2, wherein said catheter and catheter hub are tubular and concentric.

Claim 5

Dependent Claim 24 words

The catheter assembly of claim 3, wherein said lever is spring-loaded so that in its normal position said lever does not occlude said catheter.

Claim 6

Dependent Claim 28 words

The catheter assembly of claim 4, wherein said lever further includes a tab insertable through said means in said catheter assembly such that such tab occludes said catheter.

Claim 7

Dependent Claim 37 words

The catheter assembly of claim 1, wherein said catheter is formed from a material having a memory so that when said occludable means does not occlude said catheter, said catheter returns to a position permitting fluid flow.

Claim 8

Dependent Claim 11 words

The catheter assembly of claim 6, where said material is polyurethane.

Claim 9

Dependent Claim 21 words

The assembly of claim 1, wherein said lever contains a tab located proximal said catheter and capable of occluding said catheter.

Claim 10

Dependent Claim 17 words

The assembly of claim 8, wherein said catheter hub contains a post around which said lever rotates.
