Apparatus for irradiating tubing connections

Claim 2

In apparatus for irradiating a connected pair of tubing ends for antibacterial effect therein, the improvement comprising, in combination: a housing which carries an antibacterial radiation source; drawer means slidable into and out of said housing, said drawer means defining a pair of vertical slots in opposed side walls thereof having open upper ends for receiving and positioning said connected tubing ends in the drawer means when the drawer means is in open position, and moving the tubing ends into proximity with the antibacterial radiation source by closing of the drawer means.

Claim 3

The apparatus of claim 1 in which said radiation source is a convoluted ultraviolet light bulb which defines a channel for receiving the connected pair of tubing ends, with sections of said ultraviolet light bulb positioned on opposite sides of said channel.

Claim 4

The apparatus of claim 1 in which opposed side walls of said housing lie against the side walls of said drawer means, said housing side walls defining horizontal slots which intersect the vertical slots when the drawer means is closed, to define opposed apertures at the intersections of the vertical and horizontal slots through which said tubing ends can extend to be positively positioned by said apertures.

Claim 5

The apparatus of claim 1 in which said housing comprises a pair of substantially identical hollow halves joined together at their edges, said edges defining asymmetrically positioned steps and flanges, whereby the flanges of the respective hollow halves at the joined edges overlap to block leakage of radiation from said source.

Claim 6

The apparatus of claim 1 in which said vertical slots define channels along their inner peripheries to each receive a flange carried by one of the connected pair of tubing ends, for retaining the tubing ends in a fixed position.

Claim 7

The apparatus of claim 5 in which said vertical slots are each tapered to form a narrowed, closed end.

Claim 8

The apparatus of claim 6 in which said horizontal slots are each tapered to form a narrowed, closed end.

Claim 9

In apparatus for irradiating a pair of connected tubing ends for antibacterial effect therein, the improvement comprising, in combination: a housing which carries an antibacterial radiation source; drawer means slidable into and out of said housing, said drawer means defining a pair of vertical slots in opposed side walls thereof having open upper ends for receiving and positioning said connected tubing ends in the drawer means when the drawer means is in open position, and moving the tubing ends in proximity with the antibacterial radiation source by closing of the drawer means, said radiation source defining a convoluted ultraviolet light bulb which defines a channel for receiving said connected pair of tubing ends when the drawer means is closed, sections of the ultraviolet light bulb being positioned on opposite sides of the channel for irradiation of the connected pair of tubing ends from a multiplicity of directions, the side walls of said housing lying against the side walls of the drawer means, said housing side walls defining horizontal slots which intersect the vertical slots when the drawer means is closed to define opposed apertures at the intersections of the vertical and horizontal slots through which said tubing ends can extend to be positively positioned by said apertures.

Claim 10

In apparatus for irradiating a pair of connected tubing ends for antibacterial effect therein, the improvement comprising, in combination: a housing which carries an antibacterial radiation source; drawer means slidable into and out of said housing, said drawer means defining a pair of vertical slots in opposed side walls thereof having open upper ends for receiving and positioning said connected tubing ends in the drawer means when the drawer means is in open position, and moving the tubing ends in proximity with the antibacterial radiation source by closing of the drawer means, said radiation source defining a convoluted ultraviolet light bulb which defines a channel for receiving said connected pair of tubing ends when the drawer means is closed, sections of the ultraviolet light bulb being positioned on opposite sides of the channel for irradiation of the connected pair of tubing ends from a multiplicity of directions, the side walls of said housing lying against the side walls of the drawer means, said housing side walls defining horizontal slots which intersect the vertical slots when the drawer means is closed to define opposed apertures at the intersections of the vertical and horizontal slots through which said tubing ends can extend to be positively positioned by said apertures.

Claim 11

The apparatus of claim 8 in which said vertical slots define channels along their inner peripheries to each receive a flange carried by one of the connected pair of tubing ends, for retaining the tubing ends in a fixed position.

Claim 12

The apparatus of claim 9 in which said vertical slots are tapered to form a narrowed, closed end.

Claim 13

The apparatus of claim 10 in which said housing comprises a pair of substantially identical hollow halves joined together at their edges, said edges defining asymmetrically positioned steps and flanges whereby the flanges of the respective hollow halves at the joined edges overlap to block leakage of radiation from said source.

Claim 14

The apparatus of claim 11 in which said horizontal slots are each tapered to form a narrowed, closed end.

Claim 17

The apparatus of claim 13 in which said vertical slots are tapered to form a narrowed, closed end.

Claim 18

The apparatus of claim 1 in which said drawer means has an open bottom.

Claim 19

The apparatus of claim 8 in which said drawer means has an open bottom.

Claim 20

The apparatus of claim 13 in which said drawer means has an open bottom.
