Description

FIELD OF TECHNOLOGY

The technical solution relates to laboratory glassware, namely to test tubes, and can be used in chemical, physical, biological and clinical diagnostic laboratories, for the collection, storage and transportation of biomaterial, as well as at home for self-collection of biomaterial.

BACKGROUND

It is known that the study of feces for the presence of parasites is a way to identify microscopic organisms that cause serious digestive problems and often affect a person’s well-being. Moreover, the accuracy of the results largely depends on how soon the material collected for analysis reaches the laboratory. In particular, 4 hours after collecting the material, lamblia and cysts die, and some microorganisms die within an hour after excretion of feces from the human body and they cannot be detected in laboratory conditions. In cases where the material for analysis cannot be delivered at the recommended time interval, or the collection of feces is required for several days, a special preservative Safaralieva is used.

The problem with this preservative is that Safaraliev’s preservative is toxic. When working with a reagent, the rules for safe work and personal hygiene measures, for example, such as:

wear disposable plastic or rubber gloves, as human feces are potentially infected material, capable of storing and transmitting bacterial pathogens for a long time, namely, vegetative and cystic forms of protozoa.

skin contact, spilling, or accidental ingestion while pipetting should be avoided, as poisoning is possible.

In addition, it is also known that Safaraliev’s preservative is given in special laboratories (according to information from search sites), while the patient buys the container himself (http://netparazitam.ru/lyamblii/analiz-kala.html) or gives a glass bottle in the laboratory with a cork like penicillin vials (http://diagnoster.ru/bolezni/glistyi-parazityi/diagnostika-glistov-parazitov/).

The disadvantage of this use is the insecurity of using the preservative Safaraliev at home.

A prior art device for collecting, preparing and / or cultivating microorganisms is also known (WO 2016198715, another ES number 2596659). The device contains: a test tube consisting of two parts: a body and a cover, made together with a rod (the original is a tampon, we have a spatula), where the latter is designed to collect / collect biomaterials, including microorganisms. At the same time, the length of the rod in this technical solution (the original is a tampon, we have a spatula) is such that when the tube body is closed with a cap, its free end is placed at the bottom of the tube body, while the lower part of the tube body contains a transport medium. The claimed device for collecting, preparing and / or cultivating microorganisms allows storing microorganisms for some time in the transport medium to obtain analysis results.

The disadvantages of the above device, in addition to the fact that it is impossible to establish a transport medium, is:

the inability to ensure safe operation, since when the lid is closed, the tampon remains inside the tube, where it is constantly wetted by the drug, and when the laboratory assistant opens and removes the tampon from the tube, the solution can reach unprotected skin areas of the laboratory technician.

A device (US 4,789,639 (A)) is also known, which is a container with a transport medium, with a screw cap, inside of which is a removable rod with a tampon at the end, said tampon is immersed in a transport medium. The container includes a receiver, a tampon for transferring the sample to the liquid in the receiver, and an squeezing unit for removing liquid from the tampon after transferring the sample. The cover consists of two parts: upper and lower. The swab shaft passes through the passage in the closure. When the swab in the receiver rises while moving up the shaft, the absorbent pad at the lower end of the shaft enters the channel and contracts. Compression of squeezing squeeze liquid that drips back into the container. The device can be used in a method for preparing sample solutions in a minimum amount of liquid.

The disadvantages of the above device, in addition to the fact that it is impossible to establish a transport medium, is:

the inability to provide cheaper production of such jars due to the complex profile of the two-component lid;

the inability to ensure safety, since after removing the rod with a tampon at the end (putty knife) from the container, a hole remains in the lid, which can provide a spillage of the transport medium.

A set of test jars is also known (patent for industrial design RU 96074). The specified device is a jar and characterized by the composition of the composite elements: the outer and inner jars. In this case, the body of the jars is made in the form of a truncated cone narrowed to the bottom. On the outer jar, on the outer side surface in the upper part of the body, there are vertical protrusions in the form of ribs distributed at equal intervals relative to each other. The bottom of the jar body is made in the form of an annular section of a flat shape with a transition along the rounding radius, in two truncated cones directed into the body and ending in a flat section. The lid of the outer jar is made in the form of a cylindrical surface, passing from above into the end surface, while the top of the lid of the upper jar is made in the form of a flat section, and vertically elongated cylindrical protrusions rounded at the top are located on the sides. Also, the lid has a fixed spoon-shaped spatula.

The disadvantage of the above device is:

lack of transport environment;

fixed spoon-shaped blade that does not provide thorough mixing due to the structure of the spoon itself, since the length of the spoon does not reach the end of the container, which makes mixing with the lower layers impossible, which affects the storage conditions of the biomaterial.

A device for collecting a sample is known, which according to its technical characteristics is closest to the claimed technical solution (US 7141033 B2). The device comprises: a test tube consisting of two parts: a housing and a cover made with a rod (putty knife) designed to collect biomaterial, which can be removed after screwing the cap. After removing the rod (putty knife), the lid is closed by a sealed gasket. The lower part of the tube body contains a transport medium for storing some analysis time, while the case itself is rounded on the bottom. The rod (spatula) of the claimed device is a product, elongated in shape, along the length of the rod and having a rectangular frame at the end to allow mixing of the test substance with the medium.

The disadvantages of the above device, in addition to the fact that it is impossible to establish a transport medium, is:

the inability to ensure safety, since after removing the rod with a tampon at the end (putty knife) from the container, a hole remains that is closed by a sealed gasket, but when external forces, such as vibrations during transportation of the container, can spill the transport medium with biomaterial, which is unsafe during operation with the preservative Safaraliev.

The objectives of the claimed utility model is to create a container with Safaraliev’s preservative transport medium for taking, storing (including archival) and transporting stool preparations with subsequent research, the combination of elements of which ensures safe use, taking, transportation and convenient storage of biomaterial in a preservative at home Safaralieva.

DISCLOSURE OF THE ESSENCE OF A USEFUL MODEL

The technical result of the above task is achieved by creating a container with Safaraliev’s preservative transport medium for taking, storing, including archiving and transporting stool preparations, consisting of a lid that is worn on a jar, where the latter contains a certain amount of transport medium, and characterized in that the amount of transport medium, namely the preservative Safaraliev, is in the range from 1 ml to 2/3 of the volume of the jar, and the jar itself is corked with a screw cap.

These signs provide safe use at home, due to:

tightness, which is ensured by a screw cap.

According to one embodiment of the proposed utility model, the neck of the container jar with the transport medium inside is smooth. This feature provides the possibility of unhindered passage of a spatula with biomaterial.

IMPLEMENTATION OF A USEFUL MODEL

The claimed technical solution is a container with a transport medium - Safaraliev’s preservative, and provides the possibility of taking, storing, including archiving and transporting biomaterials, mainly feces, and consists of a jar 2 with a lid 3 and a spatula 4.

In FIG. 1-3 shows one example of the implementation of the proposed utility model, where:

the container assembly (1), while on top of the jar (2) of the container (1), the lid (3) is screwed. The spatula (4) is part of the container (1), but is a separate device, not attached to the container, and can be supplied separately. Transport medium - Safaraliev preservative (5), is poured into a container of at least 0.1 ml. In this case, the preferred embodiment is the filling of the preservative Safaraliev 2/3 of the height of the jar (an example is shown by line A). All of these container parts are made of material approved for use with biological material.

The use of the claimed technical solution is illustrated in one example.

The patient takes the container (1) with the transport medium (5) in his hands, unscrews the lid (3) of the jar (2). He picks up a spatula (4) and, depending on the consistency of the biomaterial, namely feces, uses either end of the spatula (4), namely, with the liquid consistency of the biomaterial, the end of the spatula (4) with a window is used to drain excess fluid. And with a solid consistency of biomaterial, namely feces, the second end of the spatula (4) without windows is used. In this case, precise dosages are not required, and the amount of biomaterial can be determined by eye. The declared volume of not more than 2/3 provides the ability to save analyzes and with the absence of spills of the preservative Turdyev in the case of a larger amount of biomaterial.

Then, with the same end of the spatula (4), the patient mixes the biomaterial with the transport medium (5) - Safaraliev’s preservative. The composition of the transport medium (5) is such that when biomaterial is placed in it, the vegetative and cystic forms of protozoa are immediately tinted and preserved in tinted form. The canning period can reach a year. In this case, mixing is carried out with a spatula (4), at which the ends are rounded, and he can thoroughly mix the biomaterial to the end of the jar (2) using a spatula (4), including the lower layers. Then the patient tightens the jar (3) with a lid (3), which ensures tightness, and the biomaterial does not spill together with Safaraliev’s transport medium (5), which eliminates the risk of this preservative getting into the patients hands. Container (1), can be given to patients on their hands for taking biomaterial at home.

When biomaterials, for example, feces are suspended in Safaraliev’s preservative (5), the decomposition of the biomaterial is stopped, which allows revealing the vegetative and cystic forms of protozoa in the feces during storage of the drug for 1 year.

The claimed technical solution, namely, a container with a transport medium - Safaraliev’s preservative for taking, storing (including archival) and transporting stool preparations, ensures safe use, taking, transportation and convenient storage at home of biomaterial in Safaraliev’s preservative.
