Description

The field of technology to which the utility model relates

The utility model relates to the construction of quickly erected modular structures of medical or hospital centers, as well as the creation of additional temporary bed capacity. The utility model is a wall block that can be used for the rapid construction of temporary hospitals to provide emergency and urgent care, to treat patients with infectious diseases, including COVID-19. It is preferable to use the utility model for the construction of temporary hospitals on free closed areas of constructed and commissioned facilities. Such facilities can include shopping and exhibition centers, sports facilities, etc.

State of the art

In the context of a pandemic, an explosive uncontrollable increase in the number of infected patients and limited healthcare resources, the development of designs for quickly erected structures of medical centers and mobile hospitals that meet the requirements of epidemiological safety for the prompt isolation and treatment of patients with COVID-19 is of particular importance. At the same time, the possibility of expanding the existing bed capacity by converting public areas into mobile hospitals and inpatient facilities for coronavirus patients with a large number of beds is of great importance in containing the scale of the pandemic. In particular, temporary hospitals can be deployed in shopping centers, sports complexes, as well as in any free areas of indoor premises with connected communications, including water supply, electricity, heat, air conditioning, ventilation, and water drainage. It is preferable to convert large indoor facilities with wide access roads for ambulances, free parking, as well as free spaces inside the premises for dividing them into wards, cabins and rooms using the declared wall blocks into mobile hospitals, incl. for medical personnel, while the structures and premises being constructed must be designed with the possibility of their easy disinfection. In this regard, the development of wall blocks is relevant, with the help of which it is possible to re-equip these premises for temporary hospitals in the shortest possible time.

The use of sandwich panels is known from the prior art for the construction of prefabricated structures. Sandwich panels can be made with a load-bearing frame of vertical load-bearing posts and horizontal distribution beams. However, the use of only sandwich panels of known designs as wall blocks does not provide the ability to quickly erect hospitals with intensive care units (ICU), for example, for isolating patients with COVID-19, since such ICUs must be equipped with the necessary communications and equipment for managing such patients, including fixing brackets and medical equipment to the wall panel, lighting, fire extinguishing equipment, as well as the ability to supply and connect a medical gas supply system (2 oxygen valves, 1 compressed air valve, 1 vacuum valve). In addition, the known sandwich panels are significant in weight and are also made of materials that are not applicable in medical facilities without additional insulation, as a result of which wall blocks made of such panels require additional revision, which significantly increases the deployment time of such a hospital.

The closest to the claimed solution is a wall block for the construction of modular wards for accommodating patients (US 6405491), which can be installed in a medical institution with gas, electricity and water supply lines. The wall blocks are configured with the possibility of their quick connection to each other. The wall block includes: two side wall panels fixed at a certain distance from each other, wherein one of the side panels is part of the wall of one ward, the second side panel is part of the wall of the adjacent ward; as well as end panels, an upper and lower panel, forming the internal cavity of the wall block, wherein the lower panel is made with the possibility of fixing the block to the floor of the medical institution. The panels are equipped with consoles with electrical sockets, sockets for connecting medical gases, wherein the means (channels) for supplying electrical cables and medical gases are placed in the cavity of the wall block with terminals from the side of the upper panel for connection to the gas, electricity and water supply lines. In addition, the wall unit is designed with the possibility of fastening modular equipment, including a monitor 70, pressure regulators, etc., as well as a lighting unit. The coupling outlets passing through the wall panels are located and configured on the wall panels for connection with couplings and connectors on the modular equipment for servicing patients. The lighting unit is pivotally fixed in the wall unit and includes a decorative panel and a lamp installed with the possibility of rotation relative to the axis: in the working position of the lamp, the decorative panel is located at an angle of 90° to the surface of the wall panel, in the non-working position - the decorative panel is located parallel to the surface of the wall panel with the placement of the lamp inside the wall unit. The console is also pivotally fixed in the wall unit by analogy with the lighting unit, and has a decorative surface and a working surface. In the non-working position, electrical sockets and sockets for connecting medical gases are hidden inside the wall unit, in the working position - they are available for connecting modular equipment for servicing patients to them. The wall unit also includes connecting elements made in the end panels, which are designed to be connected to the channels of adjacent wall units. Electrical cables and tubes for medical gases pass inside the wall unit to connect to the appropriate sockets.

This wall unit is configured for rapid erection of a patient ward, contains consoles and brackets for fastening basic medical equipment required to provide emergency medical care to the patient, and is designed with the ability to place communications inside the wall unit. However, this unit is characterized by insufficient reliability, does not provide the ability to place inside it a medical isolating transformer (power) used to supply medical electrical equipment, patient life support systems, other electrical equipment located in the patient's accessibility zone, with the ability to service it during operation and provide medical care to the patient. In addition, fastening sockets and valves for connecting medical gases on a rotating console is inconvenient and unreliable, requiring additional actions from medical personnel to access its working surface if it is necessary to "connect" the patient to oxygen.

The technical problem is the development of a design for a convenient and reliable side panel for a wall block intended for rapid construction on the territory of existing indoor buildings and structures of intensive care units that have the ability to connect to the building's utility lines.

Disclosure of a utility model

The technical result of the claimed utility model consists in the development of reliable side panels for the rapid assembly of wall blocks (partitions) of the intensive care unit (or intensive care wards) of a temporary hospital, where each of the panels is designed to connect two intensive care beds for the treatment of patients with COVID-19, while the wall block is designed with the ability to provide autonomous power supply for medical equipment.

The side panels of wall blocks are characterized by ease of transportation and mobility due to the unification of the side panel designs; low weight; the possibility of "manual" installation without the use of additional equipment and machinery; which facilitates the rapid construction of wall blocks (partitions) of intensive care units from side panels. The side panels are hygienic and easy to disinfect.

The technical result is achieved in that the side panel of the wall block of the intensive care unit of a temporary hospital, deployed in indoor structures with utility lines, is made for installation on a frame of vertical and horizontal elements and contains an internal layer of gypsum fiber sheet with a thickness of at least 12.5 mm, an external layer of gypsum board laminated panels with a polyvinyl chloride coating and a layer thickness of at least 12.5 mm, on which a removable protective box for utility lines, a removable horizontally oriented LED strip, fasteners and an external console with means for connecting electricity, emergency signaling, communication and medical equipment are placed.

The side panel is designed for installation on a frame made of vertical and horizontal metal elements, for example, in the form of metal profile pipes, which may contain additional horizontal elements (stiffeners), for example, in the form of wooden bars, designed with the possibility of attaching to them means for connecting electricity, emergency signaling, communication and medical equipment, located on the outside of the side panels, including lines (tubes) for supplying medical gases.

The side panel is preferably designed to accommodate two intensive care beds and has a height of no more than 3 m, a length of at least 5.5 m, for example from 5.5 to 8.9 m, and a thickness of 25 - 28 mm.

The side panel contains technological holes.

The means of connecting electricity can be implemented in the form of two groups of power electrical sockets with 4 sockets in each group and two low-current electrical sockets with double connectors. The means of connecting medical equipment contain gas sockets for compressed air, oxygen and vacuum.

The external protective box for communication lines is configured to accommodate medical gas supply lines. The fastening elements can be made removable in the form of external elements for a local fire extinguishing device, for a monitor, for a local lighting lamp.

The console can be made removable and placed on the side panel at a height of 1.5 m from the end of the panel oriented towards the floor of the indoor structure, and the removable horizontally oriented LED strip is located at the opposite end.

In addition to the ease of assembly, the declared side panel of the wall block allows for a flexible approach to designing the interior space of a temporary hospital depending on the size of the room used. The use of side panels of the declared design in the construction of medical hospitals simplifies the construction process, reduces labor costs and cost. When building medical wards from wall blocks with the declared side panels, no interior finishing and related work is required, including those related to the removal of construction waste.

The use of wall blocks with the declared side panels ensures the acceleration of the construction of intensive care units due to its optimized configuration, the presence of ergonomic and technical parameters that ensure the convenience of patient treatment and equipment maintenance. A typical side panel of a wall block for the construction of an intensive care unit has certain dimensions (3×5.5 m), which simplifies and reduces the cost of transportation from the place of its production to the construction site and the process of building a temporary hospital without the use of complex lifting mechanisms.

The wall blocks of the intensive care unit are assembled from side panels fixed on a metal frame, which are placed opposite each other, for example, at a distance of 0.8 m, and connected to each other by any means known from the state of the art (for example, using cross beams that ensure the rigidity of the resulting wall block structure). The specified distance between the side panels ensures the possibility of installing a medical isolating transformer (either single-phase with a rated power of at least 0.5 kW, or three-phase with an output line voltage not exceeding 250 V) inside the resulting wall block (wall partition) and servicing it during operation. The resulting wall block can be equipped with an inspection hatch for access to the transformer and communications located inside it, as well as top and end panels.

The simplicity of connecting the side partitions to each other allows you to independently assemble the wall blocks of the wards and the hospital without professional assistance and the use of additional fasteners, which significantly (by 1.5-2 times) reduces the cost of 1 m ² of the wall and, as a result, the medical complex as a whole. Simplicity in the implementation of the technological process, the absence of complex technical devices in it, low cost and availability of consumables ensure the economic efficiency of the hospital being built. The absence of parts made of chemically aggressive materials in the side panel of the wall block makes the technological process and the medical room built from the blocks environmentally and fire safe. Achieving short construction times for medical hospitals while providing the necessary functionality for the treatment of patients with COVID-19 in combination with environmental friendliness and low cost of building structures is an important task in increasing bed capacity during the pandemic.
