Urine analysis tubes impermeable to sunlight

Abstract

This invention relates to a urine analysis tube that is impermeable to sunlight and that can be used in urine analysis to prevent the penetration of sunlight so that the sample can be stored for a long time without its structure being affected, characterized in that it has an outer layer (1) made of plastic, ceramic or metal, which forms the outer surface of the tube, a lid (2) which is placed on the opening of the tube and is made of silicone or plastic, and an inner layer (3) made of glass or ceramic, which forms the inner surface of the tube.

Description

Field of technology:

[0001] This invention relates to a urinalysis tube which is impermeable to sunlight and which can be used in urinalysis to prevent the penetration of sunlight, so that the sample can be stored for a long time without its structure being affected. State of the art:

[0002] Nowadays, urinalysis is performed in laboratories for purposes such as disease diagnosis, differential diagnosis, and determining the severity of a disease. Urinalysis involves testing a patient's urine in a laboratory setting. Laboratory analysis uses urine samples collected at specific time periods such as 1, 2, 4, and 24 hours. Especially for 24-hour analyses, the urine sample should be stored in a clean, sterile, colored bottle. If a colored bottle cannot be found, the urine container should be stored in a dark place or the bottle should be surrounded by an opaque material. This is because if the sample in the container is exposed to sunlight, its contents will deteriorate, and the analysis results will be negatively affected.

[0003] The utility model application CN211652911U describes an "automatic sampling tube for urinalysis." The invention relates to the technical field of medical devices, in particular to an automatic sampling tube for urinalysis, consisting of a sample tube and a lid body. The lid body covers the sample tube, with an open hole in the center. A film is placed over the lid body and the open hole. By inserting the thin film into the open hole, the sampler of the urinalysis device can easily enter the sample tube to collect samples, eliminating the need for uncapping and significantly improving sampling efficiency.

[0004] The utility model application CN204719060U describes a "new sample tube for urine analysis." The invention relates to the technical field of medical equipment and includes the tube body, the test tube cap, and the liquid container. The upper part of the tube body is provided with a screw thread and connected to the upper end of the tube body. The test tube cap guides the liquid container through the paper tape. The test tube cap is equipped with a sealing membrane and an opening on the sealing membrane. The upper end of the liquid container is equipped with a heavy gauge, and the lower end of the liquid container is equipped with a small inlet opening. The middle part of the liquid container is equipped with a scale marking layer.Its simple structure, convenient operation, the detection of the direct operation of the computer can have uncapping the sample to save pollution in the transportation and volatilize and have prevented the sample from the overflow and spillage of the polluted environment scheduling problem, makes the test process easier at the same time, and it is more convenient that the postdetection sample is treated.

[0005] Urine tubes with various properties are described above. These urine tubes are designed to facilitate analysis for laboratory personnel. However, these tubes do not have a mechanism to protect the sample inside from sunlight, especially during 24-hour analyses. In this case, the structure of the sample is damaged because the analysis tube was not stored under proper conditions, and inaccurate results are obtained.

[0006] There is therefore a need for a new technology that can overcome the above-mentioned disadvantages. Definition of the invention:

[0007] This invention is a urinalysis tube that is opaque to sunlight and can overcome the above-mentioned disadvantages, characterized in that it is composed of two layers, the outer layer is made of opaque materials, the lid is made of opaque materials, the inner layer is made of a hard and sterile material, a vacuum chamber is provided between the outer layer and the inner layer, and it prevents light transmission and heat transfer.

[0008] The invention consists of two layers. The outer layer is made of opaque materials such as plastic and ceramic, preventing sunlight from reaching the sample in the tube. The lid, which is attached to the tube opening, prevents sunlight from entering because it is made of opaque material. The inner layer is made of a hard, sterile material. The air in the chamber between the inner and outer layers is extracted, preventing the sample from releasing heat into the external environment. Because the transfer of light and heat between the sample and the external environment is prevented, the sample is preserved for a long time without its structure being compromised.

[0009] Thanks to the simple attachment of the components that comprise the invention, it is easy to install, and costs are also low thanks to the short assembly time. Furthermore, the invention has a robust structure. Description of the drawings:

[0010] The invention will be described with reference to the accompanying drawings in order that the features of the invention may be better understood and appreciated, but it is not intended to limit the invention to these particular embodiments. Rather, it is intended to cover all alternatives, modifications, and equivalents which may be included within the scope of the invention as defined by the appended claims. It is to be understood that the details shown are for the sole purpose of describing preferred embodiments of the present invention and are presented for the purpose of providing the most useful and easily understood description of both the embodiment of the methods, rules, and conceptual features of the invention. In these drawings; Fig. 1 is the perspective view of the system. Fig. 2 is the perspective view of the system. Fig. 3 is the detailed perspective view of the system.

[0011] The figures which contribute to the understanding of the invention are numbered in the accompanying drawings and are listed below with their designations. Description of the reference list: 1. Outer layer 2. Lid 3. Inner layer Description of the invention:

[0012] This invention comprises an outer layer (1) made of plastic, ceramic or metal, which forms the outer surface of the tube, a lid (2) which is placed over the opening of the tube and is made of silicone or plastic, and an inner layer (3) made of glass or ceramic, which forms the inner surface of the tube.

[0013] The invention has an inner layer (3) which forms a vacuum chamber by evacuating most of the air between the outer layer (1) and itself and preventing heat transfer. Detailed description of the invention:

[0014] The parts of which the invention consists are essentially an outer layer (1), a lid (2) and an inner layer (3).

[0015] There is an outer layer (1) that forms the outer surface of the urinalysis tube. The outer layer (1) is made of an opaque material such as ceramic, plastic, or metal. This prevents light from entering the tube. A lid (2) is attached to the opening of the tube. The lid (2) is made of plastic or silicone and prevents light from entering. On the inner surface of the tube is an inner layer (3). The inner layer (3) is made of materials such as glass or ceramic. Most of the air in the space between the inner layer (3) and the outer layer (1) is evacuated, creating a vacuum area. This prevents the urine in the tube from losing heat to the outside world.
