## Abstract

A biochemical analyzer delivery system, comprising a sample feeding track (42), an advancing track (43), a recovery track (44), at least one to-be-tested sub-track (45), at least one emergency sub-track (46) and at least one return sub-track (47); the sample feeding track (42), the advancing track (43) and the recovery track (44) are parallel to each other; the to-be-tested sub-track (45), the emergency sub-track (46) and the return sub-track (47) are disposed between and perpendicular to the sample feeding track (42) and the advancing track (43), an emergency sample may enter the emergency sub-track via the advancing track (43), and then enters the sample feeding track for sample suction. The track-based delivery system can be horizontally disposed in a biochemical analyzer, and can be butt-jointed with a vertical track in the biochemical analyzer, thereby greatly increasing the buffer amount of sample holders without increasing the length of the biochemical analyzer.

## Claims

### Claim 1

A biochemical analyzer delivery system, comprising:
a sample feeding track, an advancing track, a recovery track, at least one to-be-tested sub-track, at least one emergency sub-track and at least one return sub-track; the sample feeding track, the advancing track and the recovery track are parallel to each other; the to-be-tested sub-track, the emergency sub-track and the return sub-track are disposed between and perpendicular to the sample feeding track and the advancing track; an emergency sample may enter the emergency sub-track via the advancing track, and then enters the sample feeding track for sample suction; a sample holder on the sample feeding track is delivered to the advancing track by the return sub-track for next test or to the recovery track for recovery.

### Claim 2 (depends on 1)

A biochemical analyzer delivery system of claim 1, wherein the to-be-tested sub-track, the emergency sub-track and the return sub-track are arrayed sequentially along the length direction of the biochemical analyzer.

### Claim 3 (depends on 1)

A biochemical analyzer delivery system of claim 1, wherein the junction part of the to-be-tested sub-track and the advancing track is provided with a to-be-tested sub-track inlet push plate for pushing a sample holder on the advancing track to the to-be-tested sub-track; the junction part of the emergency sub-track and the advancing track is provided with an emergency sub-track inlet push plate for pushing a sample holder on the advancing track to the emergency sub-track.

### Claim 4 (depends on 3)

A biochemical analyzer delivery system of claim 3, wherein the junction part of the to-be-tested sub-track and the advancing track is further provided with a to-be-tested sub-track inlet detector and a to-be-tested sub-track inlet baffle; the junction part of the emergency sub-track and the advancing track is further provided with an emergency sub-track inlet detector and an emergency sub-track inlet baffle.

### Claim 5 (depends on 1)

A biochemical analyzer delivery system of claim 1, wherein one end proximate the sample feeding track of the to-be-tested sub-track is provided with a to-be-tested sub-track outlet push plate for pushing a sample holder on the to-be-tested sub-track to the sample feeding track; one end proximate the sample feeding track of the emergency sub-track is provided with an emergency sub-track outlet pushing mechanism for pushing a sample holder on the emergency sub-track to the sample feeding track.

### Claim 6 (depends on 5)

A biochemical analyzer delivery system of claim 5, wherein one end proximate the sample feeding track of the to-be-tested sub-track is further provided with a to-be-tested sub-track outlet limit baffle mechanism; one end proximate the sample feeding track of the emergency sub-track is provided with an emergency sub-track outlet limit baffle mechanism.

### Claim 7 (depends on 1)

A biochemical analyzer delivery system of claim 1, wherein the junction part of the to-be-tested sub-track and the sample feeding track is provided with a to-be-tested sample in-place detector and a conventional avoiding shield; the junction part of the emergency sub-track and the sample feeding track is provided with an emergency sample in-place detector and a sequential sample, suction shield.

### Claim 8 (depends on 1)

A biochemical analyzer delivery system of claim 1, wherein the return sub-track has a return transmission rack that reciprocates among the return sub-track, the sample feeding track, the advancing track and the recovery track for delivering a sample holder on the sample feeding rack to the advancing track or the recovery track.

### Claim 9 (depends on 8)

A biochemical analyzer delivery system of claim 8, wherein the junction part of the sample feeding track and the return sub-track is provided with a return sample holder in-place detector.

### Claim 10 (depends on 8)

A biochemical analyzer delivery system of claim 8, wherein a bridging avoidance component is disposed between the advancing track and the recovery track, for bridging the advancing track with the recovery track and avoiding the return transmission rack.
