Description
The present invention relates to respiratory assistance apparatus.
Well-known this kind equipment comprise as the respiratory gas source of pressure cylinder, gas generator etc. and by as described in the control valve device of respiratory gas source air feed, the cycle and the persistent period of the respiratory gas pulse that is produced in the outfan may command of valve.
This kind equipment is independently, and only can help a patient.
By control control valve device, can cooperate patient to control the persistent period air-breathing and that exhale successively at any time, can regulate required break time by the operator simultaneously.
This type of separate equipment can use its patient to obtain best assisted respiartion.But, have a large amount of unexpected injuries and needing in the natural disaster or major accident of assisted respiartion, be necessary to provide auxiliary facilities with victim's number as much.
In general this is impossible, thereby can not be equipped with respiratory assistance apparatus for before arriving hospital some victims.Obviously this jeopardizes victim's health, even can cause death.If in time provide assisted respiartion to the victim, even be not sufficiently complete, they also can also be rescued.
Disclose the pulsed auxiliary facilities of the above-mentioned type in publication number is the patent documentation of US-A-4495946, the document points out that described equipment can be a plurality of service for patients simultaneously by a shared oxygen generator and a control valve.Obviously in this case, except the regulating impulse oxygen gas flow rate and no longer have any adjusting, just same breath cycle is defeated by all patients, this may be deleterious to some, or even fatal.
The objective of the invention is to overcome above-mentioned shortcoming and provide a kind of can be simultaneously for a plurality of patients provide in time, the effective equipment of assisted respiartion.
Therefore, according to the present invention, respiratory assistance apparatus includes respiratory gas source and by the control valve device of described respiratory gas source air feed, produce the respiratory gas pulse that cycle and persistent period controlled by base at the outfan of control valve, described equipment comprises a plurality of outfans, and each outfan is configurable gives a patient.This equipment also comprises the first group of connecting line that respectively described control valve device is connected with each outfan of described equipment, it is characterized in that this respiratory assistance apparatus comprises: second group of connecting line that described respiratory gas source is connected with each outfan of described equipment respectively, thus the outfan of each described equipment receives described first group of connecting line and described second group of connecting line;-be contained in the air flow regulator on some described first and second groups of connecting lines at least.
In addition, for the respiratory gas pulse, each patient can obtain keeping the voltage stabilizing respiratory air flow of constant malleation in lung.This constant malleation can be slowed down the influence to single respiratory frequency, it can :-make patient's alveolar keep opening; Carbon dioxide in the-discharge lung;-improvement is to patient's oxygen supply.
Therefore, the quality of the assisted respiartion that equipment of the present invention provided is very high.
For the outfan of each described equipment, described air flow regulator can comprise first cock and second cock, this cock be contained in respectively first group of connecting line with second group of connecting line that described auxiliary facilities outfan is connected on.
Therefore, by means of said structure, both may command was from the air-flow of the voltage stabilizing respiratory gas of described generator generation, the also air-flow of the described pulse respiratory gas of may command.
Another form is: each the described air flow regulator that matches with each outfan of described equipment can comprise so-called " balance " valve, and its input is connected with the second group of connecting line that is connected in described equipment output end with first group of connecting line.The stretching degree of known this type of valve is directly proportional with the gas flow rate that is received, thereby it is particularly suitable for described respiratory gas pulse is added on the air-flow of described voltage stabilizing respiratory gas.
Described control valve device is preferably adjustable, with cycle and the persistent period of adjusting described respiratory gas pulse.Equipment of the present invention can be set pulse period and the persistent period that at least roughly is fit to each patient.
In first simple embodiment of present device, described control valve device comprises all first group of control valve that connecting line is shared.Equipment of the present invention is distributed to all patients with the gas pulses of same period and persistent period, and the described cock of reuse is regulated assisted respiartion respectively, to control successive and air-flow pulse.
This shows in first embodiment, respiratory assistance apparatus according to the present invention is not best for a patient, but it can be a plurality of patients assisted respiartion is provided, although be living to accepting independent best assisted respiartion with described patient of trading off.In addition, because only need handle the cock of the gas flow rate that is used to control successive and pulse,, all can operate through the people of initial training so this equipment is very simple.
Second embodiment has higher safety and more complete, and described control valve device comprises a plurality of independent control valves, and each valve respectively is contained on first group the connecting line.
As seen the cycle of respiratory gas pulse and persistent period can be satisfied each patient's needs.
Equipment of the present invention comprises the gas-accumulating tank that is arranged on the storage respiratory gas between described respiratory gas source and the described control valve device.
Equally, described equipment also can comprise the gas-accumulating tank that is arranged on other storage respiratory gas between described respiratory gas source and the described second group of connecting line.
Described gas-accumulating tank constitutes surge chamber.
Equipment of the present invention comprises a plurality of patient's devices on one's body that are contained in respectively, and as air tube, respirator or other analog, each device is all through an outfan supply gas of described equipment.European patent EP-A-0366524 discloses the equipment with air tube.
In addition for safety, this equipment also comprises the measurement baric systerm that is connected with described independently installing device respectively.Can measure the respiratory system under the situation that any patient can not have superpressure like this.
It shall yet further be noted that publication number is that the patent documentation of EP-A-0097060 discloses the respiratory assistance apparatus with two outfans, on this outfan, can produce pulse respiratory gas or respiratory gas continuously.
