Track is transported to be pushed to the return track in outside.Rack for test tube can only be pushed into inside and transport track by existing rack for test tube pushing hands,
If the problems such as attempting to be pushed into outer side track there are strokes insufficient, mechanical interferences, reduces detection efficiency.Therefore it is badly in need of designing one kind
Novel telescopic rack for test tube pushing hands solves the problems, such as this.
The Chinese patent of Publication No. " CN108535503A ", describes automatic coagulation analyzer and application method, should
Patent summary are as follows: automatic coagulation analyzer includes sample module, reagent position module, handgrip module and into cup module etc., handgrip
Module is located in main cavity, and the test for having added sample is crawled to area is incubated by handgrip, incubates after a certain period of time, then grabbed by handgrip
It takes to magnetic bead detection zone or optical detection zone and is detected.Although this method can be realized the crawl and release of test cup, still
Its volume is big, especially on the automatic coagulation analyzer of limited space, be easy to cause test cup transfer difficult, testing efficiency by
To limitation.
The Chinese patent of Publication No. " CN108717113A ", discloses a kind of bio-chemical detector, patented technology summary
Are as follows: the detector realizes the automatic feed/discharge of rack for test tube, and is automatically sent to detection station and is detected, and realizes automatic
Change, quickly, easily detect, can satisfy the demand of mass detection.Although this method can realize test tube in a limited space
The movement of frame, but cannot by rack for test tube, side be transferred on the outside of track on the inside of the track, full automatic blood-coagulation assembly line apply by
To limitation.
