Description

The proposed utility model relates to medical equipment and is intended for medical use, in the microbiological laboratories of health care institutions and the state sanitary and epidemiological service.

To date, the state of the art of a similar purpose is characterized by the absence of a standardized set of technical means for collecting biological material of human feces and the requirements for collecting biological material of human feces and the parameters of the containers in which it is selected (volume, material, shape, sterility, the presence of graduation and etc.).

Known containers for sampling are containers made of polypropylene or polystyrene with or without graduation, with a volume of 50 to 100 ml with a spatula or a spoon separately inside the container (RU No. РЗН 2017/5591 dated 04/07/2017).

The disadvantages of such devices include partial or selective selection of material (incomplete defining) for research, violation of sterility during the collection of human feces, the possibility of infection of the selected material by the subject, ingress of other biological fluids, lack of a device for convenient collection of material (lining on the toilet).

In addition, in the containers for collecting feces of a person it is not possible to put the full result of the deformation. The collection of human feces requires the use of additional devices for the deformation and further selection of human feces in the container. With partial or selective collection of human feces in contact with oxygen, anaerobic bacteria die, which are the main evaluation link in assessing dysbiotic disturbance of human microflora, from the selected biological material.

From the prior art, the closest analogues have not been identified.

Achievable when using the proposed utility model, the technical result is to provide a unified approach to research on the assessment of dysbiotic disorders of human microflora by collecting complete deformation of biological material (feces) and preserving the entire microbial volume contained in biological material.

The technical result is achieved by the fact that the device for collecting biological material of human feces for medical purposes, is a universal lining on the toilet bowl in the form of a regular rectangle with a round hole in the center, in which there is a volumetric body designed to collect biological material of human feces, with the possibility of free insertion and its removal from the hole, the bulk body is a transparent container with a diameter of 144 mm and a spacing of 59 mm with a transparent lid with a diameter of 144 mm 17 mm high, made of a synthetic thermoplastic non-polar polymer that can withstand temperatures of 160-180 degrees Celsius, has high resistance to acids, alkalis, salt solutions and other inorganic aggressive environments, while the universal lining on the toilet is made of a material based on polyvinyl chloride (PVC) and has a thickness of 3 mm, a length of 320 mm, a width of 200 mm, a distance along the length of the lining on each side to the hole on one side is 25 mm and on the other hand 47 mm, a width distance from each edge to the hole TIFA - 95 mm diameter holes disposed inside lining of 130 mm.

The proposed design allows the entire process to be carried out using a standardized set of technical means for collecting the complete deformation of biological material (feces).

The presence of a voluminous body in the form of a container with a lid designed to collect biological material of human feces, with the possibility of providing a free insert and removing it from the hole, allows you to save the entire microbial volume contained in the defect product - feces, while the delivery technology of the collected biological material for research is fully ensured for the presence of bacteria, including aerobes and anaerobes, fungi, viruses and parasites, excluding additional infection of biological material m.

The choice of parameters for a transparent container with a diameter of 144 mm and a spacing of 59 mm with a transparent lid with a diameter of 144 mm and a height of 17 mm is determined by its versatility and allows you to collect feces for one adult deformation, preserve the entire microbial and parasitological landscape before laboratory studies and, by its design, is suitable under any toilet bowl of any producer (production of Russia, Italy, France, Czech Republic).

The implementation of the container with a lid made of synthetic thermoplastic non-polar polymer, which can withstand temperatures of 160-180 degrees Celsius, has high resistance to acids, alkalis, salt solutions and other inorganic aggressive environments, which ensures the delivery of feces for laboratory purposes in integrity, since feces are not affected on the properties of the container (do not decompose it) and the container, in turn, does not adversely affect the biological material of human feces, moreover, for sterile selected ma Methods and material for laboratory container must be sterile, i.e. additional contamination of the biological material of human feces is excluded, and the claimed container can be sterilized at high temperatures.

The universal lining for the toilet is made of PVC-based material and has a thickness of 3 mm, a length of 320 mm, a width of 200 mm, a distance along the length of the lining from each side to the hole on one side is 25 mm and on the other hand 47 mm, the width from each edge to the hole is 95 mm; the diameter of the hole located inside the lining is 130 mm. The dimensions of the pad are selected on the condition that the pad is suitable for any toilet of any manufacturer (manufactured in Russia, Italy, France, Czech Republic) and the container with the declared parameters is placed in it, designed in such a way that excludes urine from entering the container with feces, That is an essential condition for collecting feces for research.

The proposed device is additionally equipped with a bag for packaging, storage and transportation of a transparent container, both with collected biological material and without it, on the outside of which an indicator is applied, allowing to distinguish sterilized products from unsterilized ones.

The bag is made of brown moisture-resistant paper self-adhesive for steam, air, steam formaldehyde, ethylene oxide and radiation sterilization "Steri ^® ", easily permeable to the appropriate sterilizing agents, the bag is sealed when closed, impervious to microorganisms, preserving integrity after sterilization with the following characteristics that meet the requirements of GOST ISO 11607 2011, EN 868; an indicator of class 1 is applied on the outside of the bag, which makes it possible to distinguish sterilized products from unsterilized ones; do not require additional equipment for tight sealing; has a self-adhesive valve; the shelf life of sterility is up to 24 months, the warranty shelf life is 24 months (TU 9398-020-11764404-2004).
