Abstract
The utility model discloses a pressure regulating device of negative pressure suction in an air pressurization oxygen cabin, which belongs to the field of hyperbaric oxygen therapy devices and structurally comprises a cabin body and a suction bottle. The suction bottle is disposed inside the cabin body and respectively communicated with a suction pipe and an exhaust pipe, an air capacitor, an air resistor, a jet vacuum pump and a compression air valve are connected in series onto the exhaust pipe, and a branched circuit mounted with a fixed differential reducing valve and a bypass valve is connected in parallel onto the exhaust pipe. Compared with the prior art, the pressure regulating device of negative pressure suction in an air pressurization oxygen cabin has the advantages of reasonable design, easy processing, convenient operation, flexible pressure regulation and the like.
Description
Technical field
This utility model relates to the hyperbaric oxygentherapy apparatus field, specifically the regulator of vacuum suction in the air pressurization oxygen cabin.
Background technology
Air pressurization oxygen cabin is the airtight manned pressure vessel that is used for hyperbaric oxygentherapy, and hyperbaric oxygentherapy relates to clinical each section, and indication is widely arranged.The patient who carries out hyperbaric oxygentherapy has many critical patients of being, usually needs to inhale the expectorant operation in therapeutic process, therefore is provided with negative pressure suction device in the cabin.The limit negative pressure value of negative pressure suction device can reach 2Mpa in the now general cabin, and the medical negative pressure suction that is not accordant to the old routine is to the requirement (0.04-0.07Mpa) of negative pressure source, the actual very behaviour's inconvenience of doing.When if high negative appears in misoperation, easily patient is damaged.In addition,, force down when certain value, attract negative pressure little, can't attract to operate, be unfavorable for during this period nursing patient in the cabin because the negative pressure of negative pressure device is decided by that the cabin presses in the cabin.
Summary of the invention
Technical assignment of the present utility model is at above weak point, provides a kind of easy to operate, pressure to regulate the regulator of vacuum suction in the air pressurization oxygen cabin flexibly.
The technical scheme that its technical problem that solves this utility model adopts is: this regulator comprises cabin body and suction bottle, suction bottle is arranged in the body of cabin, suction bottle is communicated with suction catheter and exhaustor respectively, be in series with air-capacitor, vapour lock, jet vacuum pump and compressed air valve on the exhaustor, the diverter branch that uniform-pressure-drop valve and bypass valve are housed also in parallel on the exhaustor.
Vacuum table, pressure regulator valve and suction valve are installed on the described exhaustor.
Operation principle:
When the cabin internal pressure is higher than critical field, uniform-pressure-drop valve is opened, diverter branch is inflated to air-capacitor, the throughput of vapour lock is to attract flow and bypass flow sum, and its pressure drop changes with the variation of flow, and the pressure of air-capacitor also changes thereupon, the variation of pressure feeds back to uniform-pressure-drop valve, influence the flow of uniform-pressure-drop valve, realized automatic adjusting, keep suction pressure to be lower than 0.07Mpa pressure.Regulate pressure regulator valve, suction pressure can change at 0.04-0.07Mpa, even regulate improperly, also the superpressure situation can not take place.
When the cabin internal pressure was in critical field, jet vacuum pump was shut down, and utilized the cabin living negative pressure of cutting down output, and attracted air-flow to discharge.
When the cabin internal pressure is higher than critical field, uniform-pressure-drop valve is opened, diverter branch is inflated to air-capacitor, the throughput of vapour lock is to attract flow and bypass flow sum, and its pressure drop changes with the variation of flow, and the pressure of air-capacitor also changes thereupon, the variation of pressure feeds back to uniform-pressure-drop valve, influence the flow of uniform-pressure-drop valve, realized automatic adjusting, guarantee that pressure is in critical field pressure.
The regulator of vacuum suction is compared with prior art in the air pressurization oxygen cabin of the present utility model, have reasonable in design, be easy to processing, easy to operate, safe and reliable, pressure is regulated characteristics such as flexible.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Accompanying drawing is the structural representation of the regulator of vacuum suction in the air pressurization oxygen cabin.
Among the figure: 1, cabin body, 2, suction bottle, 3, suction catheter, 4, vacuum table, 5, pressure regulator valve, 6, suction valve, 7, exhaustor, 8, bypass valve, 9, uniform-pressure-drop valve, 10, air-capacitor, 11, vapour lock, 12, jet vacuum pump, 13, compressed air valve.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The regulator of vacuum suction in the air pressurization oxygen cabin of the present utility model, its structure comprises cabin body 1 and suction bottle 2, suction bottle 2 is arranged in the cabin body 1, suction bottle 2 is communicated with suction catheter 3 and exhaustor 7 respectively, vacuum table 4, pressure regulator valve 5 and suction valve 6 are installed on the exhaustor 7, exhaustor 7 is in series with air-capacitor 10, vapour lock 11, jet vacuum pump 12 and compressed air valve 13, the diverter branch that uniform-pressure-drop valve 9 and bypass valve 8 are housed also in parallel on the exhaustor 7.
Its processing and fabricating of regulator of vacuum suction is very simple and convenient in the air pressurization oxygen cabin of the present utility model, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
