SU128574A1 - Universal apparatus UNA-1 for inhalation anesthesia - Google Patents

Description

Known anesthesia machines can work only with a closed and semi-closed breathing system - In this case, with a closed system, they have a rather high resistance to breathing (up to 10-12 m-i water. Art.). In addition, they do not provide a mixture of air and oxygen; The evaporators do not have smooth adjustment, and when artificial respiration is required, the use of additional special equipment is required.

The proposed universal apparatus for inhalation parks of the UNA-1 is free from these disadvantages. An injector is introduced into it, which delivers pure oxygen or a mixture of oxygen and air, and also uses a ventless evaporator, which allows anesthesia to be carried out with any concentrates necessary for the operation. The transfer from one anesthesia system to another is made by simply switching devices.

The device uses a prefix for controlled manual breathing with active inhalation and exhalation and with active inhalation and passive exhalation. Resistance to breathing during anesthesia is reduced 5-b times compared to known devices. The device is designed to use four gases: nitrous oxide, cyclopropane, oxygen or carbon dioxide. The supply of gases is carried out from standard cylinders, giving, 1He 11e is reduced by special medical reducers.

The drawing schematically shows a universal apparatus for inhalation anesthesia INA-1. The dosage of gases in the apparatus is carried out using rotameters /, designed to supply up to 10 liters per minute of oxygen and nitrous oxide and 1.5 liters per minute of cyclopropane and carbon dioxide. For supplying large quantities of gas at a time, there are emergency oxygen and nitrous oxide buttons, which provide a maximum of 128574

filling of the ptilitrov bag within 10-15 sec. The dosage of volatile drugs is from an evaporator 2 for ether with a working capacity of 250 ml and a small evaporator 3 for another drug with a working capacity of 100 ml. The device has two replaceable adsorber 4 with a capacity of 700 g of soda lime each. Switching from one adsorber to another is carried out by valve 5 and can be performed during the operation without interrupting the anesthesia. Crane 6 switches i (a work with an evaporator or an open system (without supplying gases from cylinders) The apparatus is equipped with a breathing bag 7, and with a fur for manual, manual breathing 8. Switching from fur to a siding is performed by a crane .9 In the apparatus there are three safety valves — on the mixing chamber of the dosimeter — a valve 10 set to a constant pressure value in a range of 50 to 300 mm water flow - clan 11 and a valve 12 for adjusting the pressure during spontaneous breathing from 6 to 20 mm water flow The apparatus provides the ability to work with the closed, semi-closed, half-open. In order to connect a small evaporator, in the supply trins, independently of the recirculation system, there is a transition nipple that allows the trilenic evaporator to be positioned n. barely a dosimeter There is an injector 13 on the apparatus for supplying a mixture of oxygen with air; The apparatus is attached with a set of adsorbers for an anatomical system with capacities of 600, 350 and 170 g of soda lime, special squares for an anatomical system, a tee 14 with a valve for attaching a mask / 5.

The device also has an inhalation valve 16, an exhalation valve U7, a breathing apparatus 18 and gas cylinders 19.

The device is mounted on a rack that can be easily moved on rotating wheels.

Subject invention

Claims (1)

one; The universal apparatus for inhalation anesthesia, UNA-1, containing a mask with inhalation and expiratory valves, gas cylinders, a pressure regulator, a safety valve and an evaporator, is required in order to ensure all modern operations appropriate anesthesia, with any content. concentrations, reduced breathing resistance during anesthesia and the possible supply of pure oxygen and a mixture of oxygen with air, an injector, a vacuumless evaporator, was introduced into it, as a result of which the design makes it possible to perform anesthesia with a closed, half-open, half-closed, open henna system nitroxide, cyclopropane, oxygen or carbon dioxide, while switching from one system to another is accomplished by simply switching the device-. . . 2- Apparatus according to claim 1, of tl and h. So that,, in order to provide a possible implementation5. artificial respiration without the use of additional funds, a device for manual controlled breathing was introduced into the device.
