Description

The proposed utility model relates to equipment for postal technologies, namely, devices for collecting postal packets with biological samples in transport tubes for laboratory diagnostics. The utility model can be used in the collection, temporary storage and subsequent mailing of biological samples obtained in transport tubes to specialized laboratories for the production of laboratory and diagnostic research in medicine, veterinary medicine and the food industry.

A mailbox is previously known, comprising a housing with an upper slot for lowering newspapers, a drawer door and a guide plate for newspapers installed in the cavity of the drawer (see SU No. 251791, class A47G 29/122, 1969).

Also known is the mailbox, which includes the case, the drawer door, the slot on the housing cover for lowering correspondence and the upper and lower guides placed in the cavity of the drawer, and the slot for lowering correspondence is offset from the diameter of the drawer closer to the wall (see RU # 2103899, cl A47G 29/12, 1996).

Most of the known devices for the collection of mailings are designed to collect paper mailings with the maximum mechanical protection of data shipments.

A disadvantage of the known devices is the impossibility of collecting and temporary storage of postal packages with biological samples in transport tubes, since there are no conditions for collecting postal packages, there are no conditions for maintaining biological safety, tightness and thermal stability of the internal environment of the device.

Known autonomous cooled container for transporting tubes with blood, containing a box of two pivotally connected parts and a lid. The box is an isothermal cap, made of two parts, in the cavity of which there are test tubes, the cap is sealed by means of a membrane. Cooling is carried out using a Peltier effect module, which is powered by batteries controlled by a thermostat (see French application 2621685, class F25B 21/02, publ. 1989).

The disadvantages of the known devices are cumbersome and complexity in its manufacture. When functioning and especially when opening the lid, conditions are created for cold outflow into the environment.

Also known is a stationary or mobile thermal container for cooling insulin, which contains a thermally insulated storage chamber on the outer surface, connected through two adapters and a Peltier effect energy transducer, with an external radiator for cooling which has a fan. The chamber contains a cassette with insulin ampoules. The thermal container is equipped with a thermal sensor (see Application EPO 0248120, cl. F25B 21/02, publ. 1987).

The presence of radiator and fan located outside the case increases the dimensions and complicates the design of the device and its operation. The thermal container includes an electronic device (a regulator and a network switch) made in the form of separate units that are included in the container package. At the same time for autonomous power car battery is required. It also creates inconvenience in operation.

The closest in technical essence to the proposed device is a thermal container, comprising a housing in which there is a chamber with a lid thermally insulated on the outer surface. The body is made of aluminum alloy with a reflective coating. The camera is made in the form of an open-top tank, installed by the bottom part on the supports. Inside the chamber there are guides for installing ampoules with medicines and the top of the chamber is closed by the number of ampoules with transparent swivel plates of heat-insulating material. The thermal container has four separate energy converters with an adapter operating on the Peltier effect, evenly spaced along the outer surface of the chamber. A temperature sensor is placed directly on the outer surface of the chamber. The thermal container is used as a portable container for storage and carrying of medical preparations, with ensuring the specified temperature conditions of their storage in the range of ambient temperatures from -10 to + 50 ° С (see RU №2005965, F25B 21/02, 15.01.1994) .

A disadvantage of the known device, taken as a prototype, is the impossibility of using it as a stationary device for collecting postal packets with biological samples in transport test tubes for laboratory diagnostics, due to the absence of postal packets in the device of the scanning device. The known device also lacks an infrared heater, a sealing valve and a bactericidal ultraviolet irradiator for disinfecting the internal environment of the device. There are no conditions for disposing a disposable two-layer polymer bag (for medical waste class B is yellow, 16-20 microns thick), the presence of a dry adsorbent layer with a disinfectant substance is not indicated on the bottom of the polymer bag, there is no anti-vandal protection.

The technical result is also achieved by the fact that a bactericidal ultraviolet irradiator is installed on the lower surface of the upper part of the device, on the one side of the receiving chamber, and an infrared heater connected to the thermostat is installed on the opposite side of the receiving chamber.

Distinctive features of the claimed device are:

- the presence of a sealing valve opening the passage from the rectangular channel to the receiving chamber of the device and hermetically closing it after passing through the postal bag ensures the tightness of the internal environment of the device and does not allow particles of biological material to go outside when the postal bag and transport tube with biological sample is damaged;

- the presence in the repository of postal packages of a bactericidal ultraviolet irradiator and polymer bag with a dry mixture of the adsorbent with a disinfectant substance at the bottom allows, if the postal bag and the transport tube with biological sample is damaged, to neutralize the pathogenic microorganisms and determine the biological safety of using the entire device;

- the presence of a heater, cooling elements and a heat-insulated body ensures the thermal stability of the internal environment of the device, which does not allow pathogenic microorganisms to multiply inside the transport tubes with biological samples - this also determines the biological safety of using the entire device;

- execution of the sheet metal device body - determines the presence of the device tightness and increases the security of the internal environment of the device - which also determines the biological safety of using the whole device;

The upper part 1 and the lower part 2 of the device are connected by means of two reinforced outer hinges 7 located on the outer rear surface of the device at the junction of the connection between the upper and lower parts of the device. On the outer side surfaces of the device at the interface of the upper 1 and lower 2 parts of the device there are screw locks 8, which firmly connect both parts of the device into a single unit. On the outer bottom surface of the device, the fasteners are made in the form of rubber pads 9 to exclude external temperature transfer to the steel envelope 3 of the device from the adjacent surface. The external surface of the device is painted in “silver metallic” color or “white metallic” color to exclude heat from solar radiation. The steel case of the device is grounded.

The upper part of the device, receiving and control part 1, on the outer front surface of which is located an external rectangular opening 10 used to receive postal packets. The outer rectangular hole 10 continues inwards in the form of a rectangular channel 11 up to 10 cm deep. Scanning device 12 is installed in the upper wall of the rectangular channel. A sealing valve 13 separates the rectangular channel 11 from the receiving chamber 14. The sealing valve 13 opens the passage from the rectangular channel 11 to the receiving chamber 14 only after a positive scan of the mail package. Receiving chamber 14 is made in the form of an open-down container, which opens into the capacity 15 of the mail package storage. The dimensions of the receiving chamber 14 correspond to the dimensions of postal packets with transport tubes with biological samples located inside them. The side edges of the sealing valve 13 are installed in parallel grooves of the side vertical guides 16. In these guides, the sealing valve 13 can slide up or down under the action of the electromagnetic solenoid 17. The scanning device 12 is connected to the control unit 18, which regulates the operation of the electromagnetic solenoid 17 and most regulates the position of the sealing valve 13.

Also on the lower surface of the upper part of the device, which is facing downwards, a bactericidal ultraviolet irradiator 20 is installed to the left of the receiving chamber and a infrared heater 20 to the left of the receiving chamber, and an infrared heater 21 to the right of the receiving chamber. Infrared heater 21 is connected to a thermostat 22 devices. Electric power to all devices of the device is provided from a common power supply unit 23, from which an external electrical cable 24 extends to supply power from an external electrical network.

The lower part of the device, the storage of 2 mail packages, is made in the form of a storage tank opened up, surrounded by a thick heat-insulating shell 4 and a thick steel shell 3 of the device. The lower part 2 of the device with its upper edges is hermetically connected to the lower edges of the upper part of the device, the receiving-control part 1. Hooks 25 are located on the inner surfaces of the upper edges of the storage container of the postal bags, behind which are mounted the edges of the polymer bag 19. The entire inner surface of the postal storage container 15 The packages are lined with a disposable two-layer polymer bag 19 (for medical waste, class B is yellow, between 16 and 20 microns thick). At the bottom of this disposable polymer bag 19 is a layer of a dry mixture of the adsorbent with a disinfectant. In the lower part of the storage of postal packages, along the perimeter, through the thermal insulation layer 4 and the wall of the storage container 15, 4 grooves are laid, 1 groove on each side of the device. The notches are laid to the inner surface of the steel shell 3 of the device. In each cavity there is 1 Peltier cooling element 26, which are attached to the inner surface of the steel shell 3. The section of the outer steel shell 3 of the device adjacent to the Peltier element 26 functions as a heat dissipating and heat dissipating radiator. Air cooling with these Peltier elements 26 inside the container 15 of the mail package storage is possible up to 0 degrees Celsius. Maintaining the set temperature inside the tank 15 of the mail package storage is performed automatically by the thermostat 22 of the device.

The device works as follows. When the postal package is inserted into the external rectangular opening 10, the postal package is immersed in the rectangular channel 11 to a depth of 10 cm. With a positive scanning of the postal package, the sealing valve 13 rises, under the action of the electromagnetic solenoid 17, the passage to the storage container 15 2 postal packages . The postal package is advanced by the sender deeper into the receiving chamber 14, after which the postal package falls into the storage container 15 of postal packages into the lumen of a disposable polymer bag 19. After that, the sealing valve 13 goes down, hermetically closing the inner opening of the rectangular channel under the action of electromagnetic solenoid 17. When the temperature rises in the lumen of the container 15 of the storage of mail packages above the set temperature, the thermostat 22 triggers, which activates the Peltier cooling elements 26. P After reducing the temperature in the lumen of the storage container 15 of mail packages to the set temperature, the thermostat 22 turns off the Peltier 26 cooling elements. When the temperature in the lumen of the storage tank 15 drops below the set temperature, the thermostat 22 turns on the infrared heater 21. After the temperature in the lumen rises tanks 15 store mail packages to the set temperature, thermostat 22 turns off the infrared heater 21. For disinfection of the internal environment of the store mail packets continuously working germicidal ultraviolet irradiator 20, and the air decontamination inner surface of the container 15, storage of postal packages and polymeric disposable bag 19. In addition to the bottom of the polymeric bag 19 filled disposable dry adsorbent bed with disinfectant. If the postal bag is damaged and the biological sample is poured from the transport tube, the adsorbent absorbs spilled liquid and the disinfectant neutralizes possible pathogenic microorganisms.

When filling the storage tank 15 with postal packages with a certain number of postal packages, the control unit 18 closes the outer opening with a sealing valve 13 and stops receiving new postal packages until the next service, and also sends a signal that the device is being filled by cellular telephone. Then a worker arrives, who opens the side screw locks 8 with the key, lifts up and retracts the upper part 1 of the device, and then takes out the full disposable polymer bag 19 with postal bags. Next, it replaces it with an empty polymer disposable bag 19. The edges of the empty polymer disposable bag 19 are fixed on hooks 25 located on the inner surfaces of the upper edges of the container 15 of the mail bags. After replacing the polymer disposable bags 19, the employee performs the service maintenance of the device. Next, the upper part 1 of the device is lowered, the screw locks 8 are closed. The device is again ready for operation.
