Description
Technical field
This utility model relates to a kind of timing constant current oxygen gauge.
Background technology
Critical patient, various postoperative patient and dyspnea patient clinically; all applying oxygen sucks; but the flow valve of oxygen gauge is often loosening; so sometimes, oxygen flow is too low or too high; all do not reach the object for the treatment of, and in existing technology, product can, because patient is to producing query the service time of oxygen gauge, produce the situation that can be interrupted oxygen uptake in oxygen uptake process; patient's oxygen time exists uncertainty, therefore usually can produce dispute.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of easy to use, simple in structure, not only can avoid flow too high or too low, also can accurately carry out the timing constant current oxygen gauge of intermittent timing.
For addressing the above problem, this utility model adopts following technical scheme:
A kind of timing constant current oxygen gauge, comprise timer, flow control valve and buoy district, described timer top is provided with timing trigger switch and reset switch, described timing trigger switch and reset switch are all articulated and connected with timer, described flow control valve is by oxygen output interface, graduation indication fixed disk, spring reset button and adjusting knob form, the graduation indication line corresponding position of described graduation indication fixed disk is provided with rectangular depression, described spring reset button is rectangular rectangle, described spring reset button snap is held in rectangular depression, described timer one end is provided with annular protrusion, described flow control valve one end is provided with the annular groove holding mutually with annular protrusion, described flow control valve and buoy district are tightly connected.
As preferably, the rectangular depression place of described graduation indication fixed disk is provided with corresponding number of division.
As preferably, described buoy district is provided with corresponding index.
The beneficial effects of the utility model are: owing to being provided with graduation indication fixed disk and spring reset button, can utilize card holding structure that flow control valve is fixed, avoid the loosening flow causing unstable, guarantee the constant of flow, owing to being provided with timer, timing trigger switch and reset switch, can be in intermittent oxygen supply, carry out intermittent timing, avoid producing dispute because of the problem of oxygen time, owing to being provided with ring-shaped depression and annular protrusion, can utilize card holding structure flexibly timer to be dismantled, use and pack up more for convenience.
Accompanying drawing explanation
Fig. 1 is the plane graph of a kind of timing constant current of this utility model oxygen gauge.
Fig. 2 is the structural representation of the Flow-rate adjustment valve portion of a kind of timing constant current of this utility model oxygen gauge.
The specific embodiment
Consult shown in Fig. 1-Fig. 2, a kind of timing constant current oxygen gauge, comprise timer 1, flow control valve 2 and buoy district 3, described timer 1 top is provided with timing trigger switch 4 and reset switch 5, described timing trigger switch 4 and reset switch 5 are all articulated and connected with timer 1, can utilize timing trigger switch 4 and reset switch 5 to carry out intermittence timing, when not using, press timing trigger switch 4 and stop timing, during use, press timing trigger switch 4 and start timing, need not make to press reset switch 5 is convenient to use next time, described flow control valve 2 is by oxygen output interface 6, graduation indication fixed disk 7, spring reset button 8 and adjusting knob 9 form, the graduation indication line corresponding position of described graduation indication fixed disk 7 is provided with rectangular depression 10, described spring reset button 8 is rectangular rectangle, described spring reset button 8 is held in rectangular depression 10, press spring reset button 8 and can carry out adjust flux with adjusting knob 9, after completing, adjusting again presses spring reset button 8, can block graduation indication fixed disk 7 is fixed, described timer 1 one end is provided with annular protrusion (not shown), described flow control valve one end is provided with the annular groove (not shown) holding mutually with annular protrusion, card holding structure is flexible, can arbitrarily dismantle and assemble, described flow control valve 2 is tightly connected with buoy district 3
Rectangular depression 10 places of described graduation indication fixed disk 7 are provided with corresponding number of division, are convenient to observe size and operate.
Described buoy district 3 is provided with corresponding index, is convenient to observe size and operates.
In use, utilize the annular protrusion of timer 1 one end to be held in the ring-shaped depression of 2 one sections of flow control valves, then press spring reset button 8, with adjusting knob 9, carry out adjust flux, after adjusting completes, again press spring reset button 8 and block graduation indication fixed disk 7, finally press timing trigger switch 4 and can start timing, as started intermittence oxygen supply midway, can be according to circumstances during accommodatometer trigger switch 4 carry out intermittent timing, after being used to complete, press reset switch 5 and will reset the time.
The beneficial effects of the utility model are: owing to being provided with graduation indication fixed disk and spring reset button, can utilize card holding structure that flow control valve is fixed, avoid the loosening flow causing unstable, guarantee the constant of flow, owing to being provided with timer, timing trigger switch and reset switch, can be in intermittent oxygen supply, carry out intermittent timing, avoid producing dispute because of the problem of oxygen time, owing to being provided with ring-shaped depression and annular protrusion, can utilize card holding structure flexibly timer to be dismantled, use and pack up more for convenience.
The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement all should be encompassed in the new protection domain of this practicality and be as the criterion.
