A sample collecting and preprocessing apparatus according to an embodiment of the present invention is a sample collecting and preprocessing apparatus for collecting and pre-processing a target sample using an extraction solution, comprising a solution bag holder 100, A solution bag 200 and a sample input rod 300 injected into the solution bag 200.

Description

[0001] APPARATUS FOR COLLECTING AND PREPROCESSING SAMPLE [0002]

The present invention relates to a sample collecting and pretreatment apparatus, and more particularly, to a sample collecting and pretreatment apparatus capable of extracting a sample to be analyzed, particularly a biomarker in a snot, and directly applying the sample to a detection kit or the like.

Blood, tissue, and other invasive specimens not only cause patient pain during sampling, but are also uneconomical in terms of time and manpower.

Therefore, non-invasive specimens which do not cause pain to the patient and can be easily sampled in a relatively short time are widely used for diagnosis of diseases and the like, and typical examples are runny nose.

Since the concentration of biomarkers present in the nasal mucosa is very variable depending on the collection method, in order to ensure the accuracy and reproducibility required for the diagnosis, it is necessary to standardize the collection and treatment of the sample and to minimize the loss of the biomarker to be analyzed A sample pretreatment device is needed.

In general, centrifugal separation and extraction methods are used as pretreatment methods for runny nose collected by absorbing material. However, in order to use centrifugation, a separate device and a container are used. Since centrifugation must be performed directly, it is inconvenient to use by the general public, and the process is also complicated, making it difficult to be used for on-site diagnosis or self-diagnosis. In the case of the extraction method using the extraction solution, there may be a problem in the accuracy due to the deterioration of the extraction efficiency in the spontaneous extraction, and in the active extraction through the physical stimulation such as stirring, the variable by the user can not be controlled and it may be difficult to obtain the precision and the reproducibility. In addition, there is a disadvantage in that a separate micro outlet is required to dispense a certain amount of sample with the diagnostic kit after extraction.

Therefore, in order to overcome these disadvantages, it is necessary to develop a standardized form of sample collection and pretreatment device that can easily apply non-invasive specimen of nasal sample to the detection kit easily in the field.

[ The presser plate 120 is a portion that presses the sample insertion rod 300 inserted into the solution bag 200. Since the first mounting grooves 111a and 112a are formed in a long elongated shape, the pressing plate 120 is slidable forward and rearward of the cradle frame 110 in a state of being mounted in the first mounting grooves 111a and 112a. And pushes the sample insertion rod 300 through the sliding of the pressure plate 120. When the sample input rod 300 is pushed, the sample embedded in the sample input rod 300 and the extraction solution S of the solution bag 200 can be mixed well.

The protruding plate 130 is mounted in the second mounting grooves 111b, 112b formed in the mounting portions 111, 112. The baffle plate 130 is a part that opens the mouth of the solution bag 200 mounted on the solution bag holder 100.

Therefore, the solution bag 200 can be opened only by the first hooking hook 132 and the second hooking hook 142 while being mounted on the cradle frame 100.

A first guide groove 141 is formed in the bottom plate 140 and a second guide groove 131 is formed in the opening plate 130 at a position corresponding to the first guide groove 141. The first guide groove 141 and the second guide groove 131 are gathered to form a guide groove 170. The sample insertion rod 300 is inserted into the solution bag 200 through the guide groove 170.

It is preferable that first threads 131a and 141a are formed in the first guide groove 141 and the second guide groove 142.

The sample input rod 300 must pass through the second receiving bag 220 so that the extraction solution S accommodated in the first receiving bag 210 can be removed from the sample input rod 300, Lt; / RTI > Therefore, it is preferable that the second bag 220 is made of a vinyl material that is easily torn even by physical force.

The sample input rod 300 is a portion for collecting a sample to be analyzed. When the sample to be analyzed is a nasal discharge, the sample insertion rod 300 is inserted into the nasal cavity of the patient to collect the nasal discharge.

The sample input rod 300 includes an input rod body 310 and a collecting unit 320 disposed at the tip of the body 310 and collecting samples to be analyzed.

In the case of the collecting part 320 of the sample input rod 300, it is necessary to quickly absorb a certain amount of nasal water, and to be able to easily escape through the extraction solution without loss of the biomarker. Therefore, it is preferable to use an absorbent material of cotton, paper, polyurethane or polyester, and it is most preferable to use a polyester material.

Experiments were conducted to see how well the snout is absorbed and recovered depending on the material of the collecting part 320. The comparative experiments were carried out using four types of materials, Cotton, Polyester (PE), Polyurethane (PU) and Paper.

Polyurethane, small (T2.4xW6.6xl12mm) PE-L: Polyester, large (T2.8xW7xL16.8 mm) PU-S: Polyurethane, small (T2. PU-M: Polyurethane, medium (T4ⅹW3xL13 mm) PU-L: Polyurethane, large (T5ⅹW6ⅹL17 mm) Paper-S: Dental absorbent paper point 80 Paper-L: Dental absorbent paper point 140 was used.

First, the volume recovery test was conducted using PBS solution. As a result, four materials (Cotton, PE-S, PE-L, and PU-L) with high recovery were selected as shown in FIG.

Next, protein recovery test was performed by adding bovine serum albumin (BSA) protein (0.1 μg / ml, 1 μg / ml) to Cotton, PE-S, PE-L and PU-L. As shown in Fig. 4- (B), PE and PU materials having excellent experimental results were selected.

Next, the BSA concentration of the model protein was changed to 0 ~ 100 μg / ml for PE and PU materials, and then the protein elution solution (PBS, pH 7.2, 1% NP-40) Proteins were extracted from PE and PU materials and protein quantification was performed by BCA assay. As shown in FIG. 5, it was found that the PE (polyester) material had the best recovery rate depending on the protein concentration change.

The input rod body 310 is formed with a second thread 311 that engages with the first threads 131a and 141a. Here, it is preferable that the first threads 131a and 141a and the second threads 311 are threads of the M4 standard.

The gripper body 310 is provided at the rear end of the input rod body 310 and has a grip 330 that is thicker than the input rod body 310.

The sample input rod 300 is guided through the guide groove 170 to the solution bag 200 through the first screw threads 131a and 141a formed in the guide groove 170 and the second screw thread 311 and the grip portion 320, A method of controlling the number of revolutions of the sample input rod 300 of the first embodiment will be described in detail.

First, the sample input rod 300 is inserted into the solution bag 200 through the guide groove 170. The second thread 311 formed on the body 310 of the sample insertion rod 300 is allowed to move freely through linear motion until it is engaged with the first threads 131a and 141a. When the second thread 311 is engaged with the first threads 131a and 141a, it can not be inserted into the solution bag 200 through a linear movement and can be inserted into the solution bag 200 only through the rotational motion. Then, when the gripper 330 comes into contact with the guide groove 170, it can not be inserted into the solution bag 200 through the rotational movement.
