The utility model discloses a chamber operation control rod of a pressure oxygen chamber. The chamber operation control rod comprises a shell and a connecting rod. The chamber operation control rod is characterized in that a rotary shaft which transversely penetrates is rotatably arranged in the shell; the bottom of the connecting rod is connected to the rotary shaft; the axes of the connecting rod and the rotary shaft are perpendicular to each other; one end of the rotary shaft is connected with a sensor which can test the rotating angle of the rotary shaft through a transmission device; and an output end of the sensor is connected with a control circuit board. The chamber operation control rod can independently drive a regulating valve, and a ventilation function which is required by an oxygen chamber can be reliably realized by matching of two control rods; the control rod does not have a neutral zero position state, and zero position is always biased in the operation process, so an available angle value of output of the same electric signal is increased, and the regulation accuracy of the control rod is improved; and by adding a side cover and a bottom cover to the shell, transmission parts and circuit elements in the shell can be well protected, failure rate is reduced, and the service life of equipment is prolonged.
Description
Technical field
The utility model relates to behaviour cabin, a kind of oxygen cabin controlling rod, particularly a kind of behaviour cabin controlling rod that is applicable to manned air pressure oxygen cabins such as medical hyperbaric oxygen chamber, diving pressurization oxygen cabin, negative pressure oxygen cabin, high-altitude.
Background technique
Manned air pressure oxygen such as medical hyperbaric oxygen chamber cabin is the operation that adds, reduces pressure in the cabin; Perhaps press operations such as carrying out ventilation under the constant situation, all be unable to do without the staff and manipulate the handwheel of machinery valve directly or rotate the instrument knob that to export control signal and realize in the cabin.At present, except that computer behaviour cabin, a large amount of oxygen both domestic and external cabin all is to lean on this clockwise or counterclockwise rotation to realize grasping the cabin, in operating process, is easy to direction is done instead, produces misoperation.
Problem to the rotary manipulation existence; In the existing technology as the patent No. be the Chinese model utility " a kind of air pressure oxygen cabin add decompression operating handle " of ZL201120044801.X a kind of air pressure oxygen cabin disclosed add the decompression operating handle; It is characterized by: it contains shell combination, the control of operating handle rectilinear path, 4～20mA output and four unit of control contact output; And control contact output unit can be divided into the output of micro-switch contact and button output two-part are secretly buried on the joystick lever top; With the rotation steel ball is the center of circle, and the supporting joystick lever moves along the straight line chute that has the cambered surface that rubs.This patent is changed into existing rotary manipulation with human action and is accustomed to corresponding to front and back linear operating, so not only can overcome and lift the fatigue that the arm turning knob brings in the past for a long time, more can avoid the staff to change wrong direction.
But above-mentioned patent also shows some imperfection of self in the lifting of accomplishing original technology; Conclusion is got up; Mainly contain following problem: first problem, an operating handle of above-mentioned patent is controlled two valves respectively, and promptly operating handle does not have electrical signal output when the neutral position; (4～20mA) control pressurization (air inlet) modulating valve are exported an electrical signal (4～20mA) control decompression (exhaust) modulating valve again backward by the neutral position to export an electrical signal forward by the neutral position; Obviously, operating handle is in the manipulation process of front and back, and the same time can only start a valve; For the simple pressurization in the behaviour cabin or the flow process of simple decompression, be satisfiable, still; For the ventilation flow process of behaviour in the cabin, be and keep the cabin and press constant ventilation must open the pressurization and two modulating valve that reduce pressure simultaneously, adopt this moment the operating handle of above-mentioned patent just can't satisfy the requirement of ventilation; Can cause oxygen concentration value rising in the oxygen cabin thus, the use in oxygen supply cabin brings potential safety hazard.
In order to satisfy the requirement of ventilation; Can adopt the method that increases by the 3rd valve; Promptly utilize the button on the operating handle top of above-mentioned patent to control a solenoid valve exhaust, cooperatively interacting with the pressurizing valve of operating handle control itself constitutes the function of ventilation again, but has produced second problem thus again; Be that the ventilation amount is the chance quantity that the factors such as endurance of type selecting and the oxygen inhalation therapy of a designing quality with working pressure, oxygen supply and discharge system in oxygen cabin treatment number, the cabin, oxygen uptake equipment change; Rather than a fixed amount, adopting the ventilation amount of the operating handle realization of above-mentioned patent is a fixed amount, this will cause the ventilation amount of treating early stage in the oxygen cabin excessive; And, can have influence on patient's result of treatment and safe in utilization in the later stage especially in the not enough phenomenon of ventilation amount in oxygen cabin treatment later stage.
The 3rd problem that the operating handle of above-mentioned patent exists is: the control fineness is not enough.The most significantly performance is that the operating handle of above-mentioned patent is done slight moving forward by the neutral position, and pressurizing valve just has a bigger aperture, causes the air inflow surge, and the inflow noise of generation is strong excessively, causes that personnel do not feel well in the cabin.
In sum, the behaviour cabin controlling rod of existing technology also exists variety of issue, can't adapt to the demand of clinical use well, also need do further improvement.
