[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a lid for a screening sample container used when analyzing a liquid sample, particularly a urine sample or a blood sample in a clinical test, and a screening sample container using the same. By forming a horseshoe-shaped thin film groove in the thin film portion provided on the lid of the container body, the horseshoe-shaped thin film portion can be easily formed when the nozzle is punctured to aspirate a urine sample or blood sample. Since it is cut and inclined downward, no scum (a piece of thin film generated by puncturing) is generated and the thin film remains on the lid, preventing scum from adhering to the tip of the nozzle when aspirating the sample and allowing the liquid sample to be accurately measured. The present invention relates to a lid for a sample container for screening which can be well sucked, and a sample container for screening using the same.

[Prior art]

 Conventionally, urinalysis has been important as a screening test for renal function tests and diabetes diagnosis because urine tests can easily collect samples and provide quick test results. It is an essential inspection item. Unlike mass examinations in clinics and hospitals, group examinations differ from examinations at clinics and hospitals in that urine is collected in test sample containers distributed in advance, collected and analyzed by a testing organization, and the results are reported. take.

[0003] These laboratories have introduced automatic analyzers for processing a large number of samples. At present, most of the automatic analyzers that are used require a pretreatment in which the urine sample in the sample container for screening is once transferred to a test tube or sample container. For this reason, extra work is required and urine may be attached to hands during transfer, which is unsanitary, and there is a risk of mistaking a sample.

In order to solve this problem, a sample container for medical examination is directly supplied to an automatic analyzer, and the upper portion of the container is cut and removed with a special blade, opened, and a nozzle is inserted through the opening to perform sampling. Technology has been developed. However, in this method, urine may be spilled or scattered due to pressure applied during cutting.

In order to solve this problem, the present applicant has provided a thin film portion having a thickness that allows a nozzle to puncture the lid of a sample container for examination, and punctures the nozzle into the thin film portion to suck a sample. A sample container for screening and a sample aspiration method have already been proposed (Japanese Patent Application No. 8-166875).

[0006]

[Problems to be solved by the invention]

 However, in the sample container for examination according to the above-mentioned application, when the nozzle is punctured into a lid having a uniform thickness, a part of the torn film falls into the container and adheres to the tip of the nozzle when aspirating the sample, This could interfere with sample aspiration.

The present invention has been made in view of such a conventional problem, and a lid for a sample container for a medical examination that prevents falling of a sting residue generated when a nozzle is punctured into the lid. In other words, an object of the present invention is to provide a lid for a sample container for medical examination, which can prevent clogging of a nozzle tip and can aspirate a sample with extremely high accuracy, and a sample container for medical examination using the same.

[0008]

[Means for Solving the Problems]

 The inventors of the present invention have conducted intensive studies to solve the above-described problems, and as a result, have found that when a horseshoe-shaped thin film groove is formed in the thin film portion provided on the lid of the container body, a nozzle is punctured in the lid. The present inventors have found that a crack is formed along the thin film groove and the thin film portion is inclined downward, so that little piercing is generated and the clogging of the nozzle tip can be prevented, and the present invention has been reached.

[0009] The lid for a sample container for medical examination of the present invention is a lid having a thin film portion for sealing the upper end of the container body and piercing a nozzle therein, wherein the thin film portion has a horseshoe shape. It is characterized by having a groove. Here, the horseshoe-shaped thin film groove is an arc-shaped groove that leaves a small part of the circumference. When the nozzle comes into contact with this lid, the horseshoe-shaped thin film groove is easily cut, but the thin film does not form a groove. Since the part is connected to the lid, the thin film part does not fall into the container. The horseshoe shape was used for forming the lid mold because it was the easiest to machine. However, even if a groove left one side of the polygon, it was a groove that left one of the vertices of the star. Even if there is, the purpose is achieved.

[0010] By forming a thinner thin film groove in the thin film portion of the lid, the thin film portion may be easily broken by a physical stimulus and may cause liquid leakage. Despite normal handling of urine samples by ordinary users of sample containers, it is necessary to strictly prevent the membrane from being destroyed. The upper part of the lid of the present invention is provided with a cylindrical projection for guiding the sample suction nozzle to the inside of the container, and the thin film part is located at the back of this cylinder. Never touch. Further, the examination sample container of the present invention has a container main body for storing the collected sample therein, and a horseshoe-shaped thin film groove formed in a thin film portion for piercing a nozzle inserted into the container main body. And a lid.

[0011]

[Embodiment of the invention]

 According to the configuration of the present invention, the sample container for examination stores the collected sample, is sealed with the above-mentioned lid, and is sent to the inspection organization.The inspection organization supplies this to the automatic analyzer, and The thin film provided on the lid of the main body is punctured with a nozzle to suck the sample contained in the container body. At this time, a crack is formed along the horseshoe-shaped thin film groove formed in the thin film portion provided on the lid, and the horseshoe-shaped thin film portion is inclined downward, so that a sting residue is left on the lid, and a stab is left on the lid. Scraps can be prevented from sticking to the tip of the nozzle, so that the sample stored in the container body can be aspirated very simply and accurately.
