Abstract

New flight motion concept. It consistsof a decrease of the front pressure of helicoplanes to lower thanthe downstream separation zone pressure. So helicoplanes are pushed forward by atmospheric air instead of being dragged as conventional aircraft are. This decrease of front pressure, according tothe Magnus phenomenon, is effected by adding to the front air flow a rotational velocity. That is done by the external surface (8)of a horizontal mixed-flow blower (11). So the blower (11) provides vertical take-off, vertical landing and initial low speed horizontal motion by its blades, and by its external surface (8), there is provided a supersonic speed in horizontal motion. The blower is incorporated in a low drag semilens-shaped hull (1, 2), being uncovered only in a front segment. Helicoplanes can accomplish low level speed of 2, 5 MACH, a ceiling range which is practically unlimited, glide capability, manoeuverability acceleration 8g, and time to ceiling 3 min.

Description

The invention relates to a time sequence control device for medical ventilators. The purpose of the invention is the provision of independent installation of respiratory frequency from the ratio of time of inhalation and exhalation. The device consists of two chains of shift registers, formed by connecting three bit counters 1,2 and 3, 4 and two binary

2

Of the eight decoders 5, 6 and 7, 8. The clock inputs C of the three bit counters of the first circuit of the shift registers are connected to a generator of 9 square-wave pulses through a frequency divider. Different stages of division together with a weekly sequence of pulses are conducted on a four-pole switch 11. The generated respiration frequencies depend on the position of the twelve pole switch 12 and are sequentially controlled in the 1Tg cycle with three-bit counters 3, 4 and binary of eight decoders 7, 8. The divider 10 frequencies are switchable exits both with stronger, and with smaller division of frequency of impulses. To implement the forms of artificial ventilation of the lungs, in which extremely long expiratory phases are necessary, the output deals with a stronger division of the frequency of the pulses. The last output pulse returns the three-bit counters of the second chain of shift registers to the initial state, which allows an independent setting of the inhalation-expiratory time ratio. 1 hp ff, 1 ill.

The invention relates to a time sequence control device for electronically controlled artificial lung ventilation apparatus using integrated circuits of sensitive equipment techniques and can be applied to anesthetic apparatus and therapeutic lung ventilation apparatus.

The purpose of the invention is the provision of independent installation of respiratory frequency from the ratio of time of inhalation and exhalation.

The drawing shows a diagram of the proposed device.

The time sequence control device consists of two known fines of shift registers formed by interconnecting two three-bit counters 1, 2 and 3, 4 and two binary ones

Of the eight decoders 5, 6 and 7, 8. Interconnection also allows sequential adjustment in such a way that the second decoder 6, 8, respectively, is activated only after the first decoder 5, 7. Switched clocks are input to the clock input from three-bit counters 1, 2 frequencies 1 _T. The pulses are generated in the generator 9 rectangular pulses, and in the divider 10 frequency and their frequency is divided appropriately. The various division stages together with the allocated pulse sequence are conducted on a four-pole switch 11, which is connected to the clock inputs C of three-bit counters 1, 2. Twelve suitable binary outputs from eight decoders 5, 6 are conducted on the twelve-pole switch 12, which is connected as e clock inputs C three-bit counters 3, 4 of the second chain of shift registers, and through the signal wire 13 with the input 0 of the three-bit counter 1.

When the signal reaches the binary output of switch 12 from eight decoders 5 or 6, a pulse is sent to the clock inputs from three-bit counters 3.5. By the same impulse, the three-bit counter 1 through the signal wire 13 and the three-bit counter 2 through communication are returned to the initial state. A new clock clocking of ί _{τ <} begins. The generated respiration rates depend on the position of the twelve pole switch 12 and are sequentially controlled in tact _ί Τϊ by _three- bit counters 3, 4 and binary of eight decoders 7. 8.

The zero binary output of eight decoders 7 is connected to input 5 of trigger 14, while twelve other binary outputs from eight decoders 7, 8 are connected to a twelve-pole switch 15, which in turn is connected to input K of trigger 14.

In the presence of a signal at the zero output of the binary of eight decoders 7, the trigger 14 outputs a signal to the next executive body (not shown).

When the signal reaches the busy output, the trigger 14 returns to its previous state and issues a signal. The output 7 of the eight binary decoders 8 is connected to the input of the element OR 16. The other input of the element OR 16 is connected via a differentiating element 17 to the closing link of the pneumoelectric transducer 18. The output of the element OR 16 has a signal connection with the zero input of a three-bit counter 3.

When the signal reaches output 7 of binary out of eight decoders 8 during further clocking, the three-bit counter 3 goes through the OR 16 element and the three-bit counter 4 returns to its original state through the connection and a new counting cycle begins with the next ί _Τι pulse.

The number of cycles from the zero binary output of eight decoders 7 to the occupied switch output gives the inspiration time, the number of steps from the busy switch output to the last binary output of eight decoders 8 expiration time.

To implement assisted ventilation, three-bit counters 3, 4 of the second chain of shift registers must be returned to their initial state at any time during the expiratory phase if the patient triggers an assistant's pulse. When a short-term closing contact of the pneumatic-electric converter 18 of the assistant's sensor (not shown), receive a sharp pulse from the direct voltage through the differentiating link 17, which through the element OR 16 immediately returns the three-bit counters 3, 4 to the initial state.

The frequency divider 10 is equipped with switchable outputs with both stronger and smaller frequency division of the pulses. To implement the forms of artificial ventilation of the lungs, in which extremely long expiratory phases are necessary, the output deals with a stronger division of the frequency of the pulses. For the realization of high-frequency forms of ventilation of the lungs, there is an output of a frequency divider 10 with a smaller frequency division of the pulses, which, together with non-interlaced pulses, provide different frequency bands within the high-frequency ventilation of the lungs.
