Abstract

A locking device for a tubing connection used in intravenous feeding. The invention comprises a body with a channel therein adapted to receive a tubing connection. The body is resiliently compressible transverse to the channel. To secure the locking device against a tubing connection, the body is compressed and a retainer installed. Once in place, the locking device prevents separation of the intravenous tubing connection between a vein insert tube and the termination of an intravenous supply tube. Installation and removal of the locking device is readily effected, thus permitting secure connection and ready separation of an intravenous fluid line without pulling or twisting.

Claims

1. In a locking device for firmly but releasably holding a tubing connection between a vein insert and supply tubing for intravenous fluid, a body formed of resilient material, said body being provided with a shaped channel extending along its length, said body being compressible transverse to said channel whereby side portions of said body on each side of said channel can be forcibly depressed toward one another, and means for releasably applying compression on said side portions of said body to forcibly depress said side portions toward one another to engage and hold both the vein insert and the supply tubing within said shaped channel of said body.

2. A locking device as in claim 1 wherein said means for releasably applying compression on said side portions of said body includes a retainer slidably attached to said body.

3. A locking device as in claim 1 wherein said body includes groove means penetrating a lower surface of said shaped channel at one end of said body thereby facilitating the forcible depression of said side portions toward one another.

4. A locking device as in claim 1 wherein said vein insert has a radially extending flange and groove means are provided in said body transverse to said channel to receive said flange.

5. In a locking device for firmly but releasably holding a tubing connection between a vein insert and supply tubing for intravenous fluid, a body formed of resilient material, said body being provided with a shaped channel extending along its length, groove means penetrating a lower surface of said channel at one end of said body whereby portions of said body on each side of said groove means can be forcibly depressed toward one another, additional groove means on the outside of said body on each side of said first named groove means, and releasable clamp means slidably engagable in said additional groove means, said clamp means being movable from an outward position wherein said body portions are forcibly depressed toward one another but remain spaced from one another, to an inner position wherein said body portions are further depressed toward one another into a locking position by said clamp means, whereby said tubing connection is held within said shaped channel of said body.

6. A locking device as in claim 5 wherein said groove means penetrating the lower surface of said channel has a longitudinal dimension which is at least half the length of said body.

7. A locking device as in claim 5 wherein said releasable clamp means is generally C-shaped in configuration.

8. A locking device as in claim 5 wherein said vein insert has a radially extending flange and groove means are provided in said body transverse to said channel to receive said flange.
