Description
Technical field
This utility model relates to the oxygen inhalation system in the medical apparatus and instruments, particularly a kind of oxygen inhalation system of accumulating timing.
Background technology
At present a lot of hospital wards have all been installed central oxygen supply system, and each sick bed is equipped with oxygen inhalation system separately, and by charge service time.So but general oxygen inhalation system does not have clocking capability often to cause the charge dispute.Existing several at present oxygen time sets occur, and can address this problem.But all there is certain deficiency in using.What have will transform pipeline, and the covering device that adds in addition that has takes up space greatly.Have that a kind of to add the effect of accumulating timing circuit on inhaler better, but because of gas, electricity are worked asynchronous, be that gas circuit is opened lagging circuit and picked up counting more, the hysteresis that circuit suspended when gas circuit was closed is also more, cause the knob angle very big, not too convenient in the use, also show slightly unfairness to patient.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can cumulative calculation the oxygen inhalation system of service time, and its gas circuit, circuit synchronous working, easy to use, simple in structure.
For achieving the above object, technical solution of the present utility model is as follows:
The oxygen inhalation system of the timing accumulated that this utility model provides comprises: gas flowmeter a, air valve b, water pot d, hour counter jumper totalisator and shell c thereof;
The detailed structure of air valve b is seen Fig. 2, the input channel b2 of the air valve b that is connected with source of oxygen is connected with the central passage of gas flowmeter a, the output channel that puts in the airway e within the water pot d is connected with gas flowmeter a output channel a1, and the pore b3 that is positioned on the air valve body 7 of water pot d upper end is connected with suction pipe joint b1 centre bore; Suction pipe joint b1 is communicated with flooded suction by flexible pipe; One side of air valve body 7 is installed timer, and described timer is made up of accumulation timing circuit, LCDs, band key gauge tap 8 and battery, and is encapsulated in the shell 9; Air valve body 7 is provided with the swivel nut 6 that an insulant is made, and it is characterized in that: the push rod 2 that the outside is provided with insulation sleeve 4 is positioned at described swivel nut 6 centre bores and turn therein, and its rear portion is provided with jump ring 3; The front end of push rod 2 sets gradually spool 10 and spring 11 in the input channel b2 of air valve body 7, and is positioned at the centre bore of the inlet suction port 12 that is fixedly mounted on the air valve body 7; The accumulation timing circuit input of described timer links to each other with air valve body 7 with jump ring 3 respectively.Spool 10 is that steel ball or end are the metalwork of sphere.Described gas flowmeter a float-ball type or pointer gas flowmeter.
The work process of the oxygen inhalation system of the timing accumulated that this utility model provides is: when turning knob 1 precession is installed on the push rod 2 of insulation on the swivel nut 6, the front end of push rod 2 at first contacts the spool 10 of sealing gas circuit, the closing of contact that is equivalent to contactor makes " timing begins " input conducting of accumulation timing circuit; Spool 10 has been backed down in the precession of push rod 2 simultaneously, and the oxygen gas circuit is opened to the aperture of suitable flow, and patient can carry out oxygen uptake.When patient does not need oxygen uptake knob 1 backward rotation certain angle, spool 10 is on the combined effect lower seal of the spring force of spring 11 and the oxygen pressure road of holding one's breath, simultaneously push rod 2 leaves spool, and " timing begins " signal disconnects, and the accumulation timing circuit is quit work and keeps data constant.When patient needs oxygen uptake once more, open air valve, the accumulation timing circuit begins to work on, the accumulation timing.Only after the staff has added up service time,, just can make the display digit zero clearing ready for using next time with private key rotating switch 8.
The oxygen inhalation system of the timing accumulated that this utility model provides has following tangible advantage:
1, easy to use.To the patient that uses and the common oxygen inhalation system before making peace is the same does not increase any new operation; Can obtain patient's statistical data service time accurately to the staff.
2, simple in structure, air valve works asynchronously with the accumulation timing circuit, and is not only easy to use, more embodies just, accurate.
