Description

Adapter for positioning trace samples and sample rack

Technical Field

The invention belongs to the technical field of biological experimental equipment, and relates to the field of accurate positioning and detection on a full-automatic analyzer by using trace patient samples, calibrators and quality control products, such as a full-automatic biochemical immunoassay analyzer, a specific protein analyzer and the like; in particular to an adapter and a sample rack for positioning a micro sample.

Background

At present, the liquid level sensor based on the capacitance detection principle is mostly adopted for detecting the liquid level in a sample tube of the high-speed full-automatic analytical instrument, so that the automatic liquid suction sampling needle can be inserted into a proper height below the liquid level for sampling, and the bottom contact firing pin of the sampling needle cannot be caused. In order to ensure that a fully automatic analyzer can accurately and automatically detect a detection object, manufacturers of the analyzer often require that the liquid level of the detection object placed in a sample tube cannot be too low, otherwise, the detection precision of the sample of the analyzer is affected and even a sample adding needle is damaged.

However, in clinical laboratories and scientific research institutions in hospitals, a small amount of patient samples or full-automatic analytical instruments on calibration and quality control products are often used for testing and analysis, and the reasons are two main reasons: firstly, many patients are infants or elderly people with special ages, blood sampling is very difficult and painful, and a small amount of detection samples can be obtained; and secondly, the prices of a plurality of calibration products and quality control products are not good, and if too many sample tubes are poured into the sample tubes at one time, the cost of the use unit of the analysis instrument is undoubtedly and greatly increased.

In order to solve the above problems, the use unit of the full-automatic analyzer especially prefers to use a centrifugal tube (abbreviated as EP tube), as shown in fig. 1, the bottom of the EP tube is V-shaped, the liquid level depth of the micro-sample can be increased, and the top of the EP tube is provided with a sealing cover, so that the full-automatic analyzer is especially convenient to store, transport and store without risk of spilling. However, because the flip cover of the EP tube is usually in a natural movement state, the EP tube rotates within 360 ° and may cause the sampling needle of the analyzer to touch the flip cover when rotating left and right and sampling up and down, resulting in a small amount of alarm striker and a large amount of damage to the sampling needle. If the flip is cut, not only is the workload of the operator increased, but if the trace sample is to be kept, the trace sample also needs to be transferred to another EP tube with a flip, which also increases the workload and the cost of use.

In addition, because the EP tube is not bar-coded, medical staff usually writes a sample number manually to record corresponding patient information, which is easy to cause human negligence and reduces the work efficiency of the medical staff.
