(67) Meanwhile, a removal unit 700 may further be provided which is disposed between the plurality of longitudinal moving units 410 and which serves to separate the sample collection member 100 from the vertical moving unit 420. After the use of the sample collection member 100, the removal unit 700 serves to separate the used sample collection member 100 from the vertical moving unit 420 in order to connect a fresh sample collection member 100 to the vertical moving unit 420.
(68) The removal unit 700 will now be described with reference to
(69) The removal unit 700 is positioned on a path along which the sample collection member 100 is moved laterally by the first laterally moving unit 430. Accordingly, when the use of the sample collection member 100 is completed, the sample collection member 100 may be positioned on the removal unit 700 using the first laterally moving unit 430, and then separated by insertion into the through-hole 701. As shown in

The jig 706 has a sliding hole 704 which is formed vertically so as to form a path along which the slide 702 moves slidably, in which the sliding hole extends longitudinally. Accordingly, the slider 702 is disposed in the sliding hole 704 formed in the jig 706 and is slidable along the sliding hole 704. The sliding hole 704 is configured such that it extends vertically so that the slider 702 can be exposed in a vertical direction.
(71) The waste box 708 is disposed below the jig 706, and is configured such that the sample collection member 100 separated from the vertical moving unit 420 is dropped into the waste box.
(72) Meanwhile, a spring may further be provided which is disposed in the sliding hole 704 and which serves to apply elasticity between the inner surface of the sliding hole 704 and the slider 702 so as to elastically bias the slider 702.

When sample testing is started, the sample collection member 100 is automatically bound to the end of the arm 423 by the longitudinal moving unit 410 and the vertical moving unit 420. The arm serves to bind the sample collection member so as to prevent internal pressure from being removed. In addition, in order to increase adhesion to the surface of a hard material, a portion of the arm, which binds to the sample collection member, may be covered with a highly adhesive material, for example, an urethane-based rubber material.

The second driven pulley 424d is provided on the other side of the second belt 424b and serves to rotatably support the second belt 424b. In particular, the pulley-belt type longitudinal driving part 424 is provided which can prevent vibration and foreign matter from being caused by friction during lateral movement, unlike a gear type, so that more accurate testing can be achieved. Furthermore, lateral vibration of the aim 423 during vertical movement can be prevented, and thus the sample collection member 100 can be accurately moved vertically. In addition, the vertical guiding rail 422 is configured to correspond to the groove, and thus vibration may further be prevented.

(125) In addition, the holder 411 may further comprise a heater configured to heat the holder 411, and a temperature sensor configured to sense the temperature of the holder 411. Thus, the sample received in the sample chamber 220, the reagent received in the reagent chamber 230, and the reaction product received in the detection part 240 may be maintained at suitable temperatures required in analysis.
(126) In addition, the holder 411 may have specific sensors that senses whether or not the sample collection member 100 and the cuvette 200 would be mounted. The sensor that senses mounting of the sample collection member will now be described with reference to
(127) In addition, as shown in, for example,
(128) Hereinafter, steps of analyzing an analyte in a sample by use of the station according to one embodiment of the present disclosure will be described briefly.
(129) After the cuvette is mounted into the holder of the station, the sample collection member is placed in the sample collection member standby chamber of the cuvette to allow insertion of the sample collection member to be recognized, and a start button for the station is clicked. Then, the cuvette moves backward, and then the information of the barcode is read by the barcode scanner, and this information is linked with the information of an ID chip, and thus the station is suitably driven depending on the kind of analyte. Accordingly, the arm is driven and a sample is suitably dispensed, and then a reaction between the sample and the reagent is performed at a specific temperature for a specific time. Next, the reaction product is dispensed into the detection part including lateral flow-type chromatography, and is developed in the chromatography membrane, and the resulting fluorescent signal is detected. Using this information, qualitative or quantitative results for a specific analyte contained in the sample are obtained. Each step appears through the display provided in the station. After completion of the analysis, the sample collection member is not present in the sample collection member standby chamber, and the cuvette is in a state mounted in the holder. This state is recognized, and a massage to remove the cuvette pops up, and the analysis is terminated.
