Abstract
The utility model relates to a medical instrument, particularly a medical oxygen pressure reducing device. The medical oxygen pressure reducing device comprises an upper valve body, a lower valve body, an air inlet screw rod, a safety valve, a main switch, a piston, an air outlet switch and an external connection rod. The utility model is characterized in that a barometer (13) is arranged between the main switch (20) and the air inlet screw rod (15). The utility model has the advantages of simple structure, convenient manufacture and lower cost because of the removal of one pressure gauge.
Description
This utility model relates to a kind of medical apparatus and instruments, specifically, is a kind of medical oxygen decompressor.
At present the medical oxygen decompressor that uses except that upper valve body, down valve body, air inlet screw rod, relief valve, main switch, piston, go out outside air cock, the extension bar, also be provided with two air gauges, complex structure, cost height.
It is a kind of simple in structure that the purpose of this utility model is to provide, the medical oxygen decompressor that cost is low.
For achieving the above object, this utility model adopts following technical scheme: it is similar that its other parts structure and existing medical oxygen subtract device, comprise upper valve body, following valve body, air inlet screw rod, relief valve, main switch, piston, go out air cock, outer extension bar, it is characterized in that: between main switch and the air inlet screw rod air gauge is set.
Prior art is compared under this utility model, and its advantage is: owing to reduced by a Pressure gauge, so simple in structure, easy to make, cost is lower.
Fig. 1 is this utility model structural representation.
Fig. 2 is Fig. 1 vertical view.
The utility model is described in further detail below in conjunction with accompanying drawing:
As accompanying drawing 1, shown in 2, this utility model at first comprises valve body (1) and upper valve body (2) down, it also comprises an air inlet screw rod (15), last pad drainage screen (14), be communicated with relief valve (22), main switch (20) and Pressure gauge (13), main switch (20) comprises airtight and watertight padding (12), sealing ring (16), press (17), control valve rod (18), end a screw (19), main switch (20) also is communicated with piston (9) and goes out air cock (4), piston (9) is set up airtight and watertight padding (12), sealing ring (11), sealing ring (10), go out air cock (4) and comprise pressure female (3), valve rod (5), end a screw (6), sealing ring (7), go out air cock (4) and connect outer extension bar (8), relief valve (22) comprises drainage screen (21), pressure cap (23) and sealing gasket (4).
