On the basis of compression and decompression controlling valve groups, an automatic protecting circuit is additionally arranged. The valve bodies of the compression and decompression electromagnetic valve in the circuit are respectively connected in series to the passageway of the air source in front of the compression and decompression controlling valve groups. Coilers are respectively connected in parallel with a photoelectric alarm and are connected in series with the circuit. A pressure gauge with electric contacts is connected in series in a compression and decompression protecting branch circuit. The pressure gauge with electric contacts is also communicated with a hyperbaric oxygen chamber through the passageway of the air source. The automatic protecting device has the advantages of flexible setting of number value of pressure, automatic completion of protecting action, sensitivity and reliability. The utility model is suitable for the compression and decompression system for a hyperbaric oxygen chamber operated by hand or by a microcomputer.
Description
This utility model relates to a kind of automatic protection circuit device, and especially a kind of medical hyperbaric oxygen chamber that is applicable to adds the automatic safety device of depressurized system.
At present, the adding of domestic medical hyperbaric oxygen chamber, decompression process, usually adopt two kinds of manually-operated and computer operations, its control mode can be summed up as three classes, promptly control the break-make of gas passage by manual operating valve, pneumatic control valve and electric control valve, all be the variation of opening in essence along with control valve, change the size of air mass flow in the turnover cabin, make add, pressure changes in the decompression process speed and numerical value satisfies pre-provisioning request, then, must make pressure stability on predefined numerical value again by artificial or computer operation valve.The common deficiency that above-mentioned three class control modes exist is: lack automatic safety device in the adding of hyperbaric oxygen chamber, the depressurized system; in case for a certain reason; carelessness appears in operator or faulty operation appears in microcomputer, and the pressure in the oxygen cabin can continue to rise or reduce, thereby causes malpractice.
The purpose of this utility model provides a kind of medical hyperbaric oxygen chamber that can effectively avoid malpractice to take place automatic safety device that adds, reduces pressure, to remedy the deficiency of above-mentioned control mode.
For achieving the above object; the technical scheme that this utility model is taked is: on the basis of the adding of original hyperbaric oxygen chamber, pressure reduction control valve group; design a kind of decompression automatic protection circuit that adds, this circuit by the contact pressure table, add vacuum solenoid valve, photoelectric alarm, on and off switch and display lamp and form.Wherein add pressure electromagnetic valve and vacuum solenoid valve is normally open solenoid valve; its valve body part is connected on respectively on pressurization control valve group and the pressure reduction control valve group source of the gas passage before; its coiler part is in parallel with photoelectric alarm respectively; be connected in the circuit then; be controlled by the electro connecting pressure gauge in the circuit jointly; electro connecting pressure gauge is connected on the centre of pressurization protection branch road and pressure reducing protection branch road, and by source of the gas passage and hyperbaric oxygen chamber UNICOM.Electro connecting pressure gauge by gas passage from hyperbaric oxygen chamber, extract at any time pressure signal and with the numeric ratio of prior setting; when the pressure in the cabin rises or drop to setting numerical value; the upper limit of electro connecting pressure gauge or lower limit contact are connected; pressurization or vacuum solenoid valve power connection also begin action; cut off the source of the gas passage; cause the cabin internal pressure to be stabilized in and set on the numerical value, meanwhile photoelectric alarm gives the alarm, and adds the decompression purpose of protection automatically thereby reach hyperbaric oxygen chamber.
Hyperbaric oxygen chamber by the such scheme design adds the decompression automatic safety device; pressure value is provided with flexibly; owing to all adopted electronic device control; protection action finishes automatically, only need 0.5 millisecond sensitive reliable, movement time; can play the automatic protection functions that adds decompression, obvious social benefit effectively.This device is applicable to that all kinds of new old models, hyperbaric oxygen chamber artificial or computer operation add depressurized system.
Accompanying drawing is the electric principle schematic that hyperbaric oxygen chamber adds the automatic safety device that reduces pressure.
Below in conjunction with drawings and Examples this utility model is described in further detail:
Among the figure; pressurization control valve group 6 of installing on the gas passage of hyperbaric oxygen chamber 1 and pressure reduction control valve group 7 are prior art; the decompression automatic safety device that adds that this utility model provides designs on this basis; it is by electro connecting pressure gauge 2; add pressure electromagnetic valve 3; vacuum solenoid valve 4; photoelectric alarm 5; on and off switch 8 and power supply indicator 9 are formed; wherein add pressure electromagnetic valve 3 and vacuum solenoid valve 4 is normally open solenoid valve; they are as the actuator of electromechanical integration; its valve body part is connected on respectively on pressurization control valve group 6 and the pressure reduction control valve group 7 source of the gas passage before; its coiler part is in parallel with photoelectric alarm 5 respectively; be connected in the circuit then; be controlled by the electro connecting pressure gauge 2 in the circuit jointly; electro connecting pressure gauge 2 is connected on the centre of pressurization protection branch road and pressure reducing protection branch road, and by source of the gas passage and hyperbaric oxygen chamber 1 UNICOM.Electro connecting pressure gauge 2 extracts pressure signal at any time by gas passage from hyperbaric oxygen chamber 1; and with the pressure value of prior setting relatively; when the pressure in the cabin rises or drop to setting numerical value; the upper limit of electro connecting pressure gauge 2 or lower limit contact are connected; the power connection of pressurization or vacuum solenoid valve 3 or 4; and begin to move; cut off the source of the gas passage; set on the numerical value thereby keep the cabin internal pressure to be stabilized in; meanwhile; photoelectric alarm 5 starts also and gives the alarm, and that realizes hyperbaric oxygen chamber jointly adds the decompression automatic protection functions.
Work process of the present utility model is an example with the pressure process of hyperbaric oxygen chamber: before hyperbaric oxygen chamber 1 pressurization, turn on the power switch 8, power supply indicator 9 luminous indication mechanisms are in running order, adjust the pointer of electro connecting pressure gauge 2, the numerical value of upper limit pressure is set by the needs of therapeutic scheme, add pressure electromagnetic valve 3 and be in normally open, operation pressurization control valve group 6, make compressed air flow on demand through adding pressure electromagnetic valve 3, pressurization control valve group 6 flows into hyperbaric oxygen chamber 1, pressure in the hyperbaric oxygen chamber 1 raises, the numerical value of electro connecting pressure gauge 2 and the pressure value in the cabin increase synchronously, when the pressure in the hyperbaric oxygen chamber 1 reaches setting numerical value, the upper limit contact of electro connecting pressure gauge 2 is connected, the power connection that adds pressure electromagnetic valve 3, add pressure electromagnetic valve 3 actions, the source of the gas passage of pressurization is cut off, simultaneously, photoelectric alarm 5 luminous warnings, so far the pressure in the hyperbaric oxygen chamber tops out, be stabilized on the numerical value of setting, this time behind the EO, the staff operates pressurization control valve group 6 makes it reset into original state, for pressurization next time is got ready.
The decompression process of hyperbaric oxygen chamber and pressure process in like manner are not repeated at this.
