Abstract
The utility model provides an oxygen concentration adjusting device, consisting of a Venturi tube (1) and a concentration control tray (6), wherein the Venturi tube (1) comprises an air inlet (3), a nozzle (2), a lateral opening (7) and an air outlet (5), the lateral opening (7) is positioned at the nozzle (2) of the Venturi tube (1) and is provided with the concentration control tray (6) as well as is communicated with air; the concentration control tray (6) is provided with a valve handle (9) and a splitter vane (12) which is provided with an air hole; the concentration control tray (6) is used for controlling the flow rate absorbing air, thereby changing the oxygen concentration of the outputted gas. The oxygen concentration has an adjustable range between 37 and 100 percent. The utility model does not use high pressure air, only uses one kind of high pressure oxygen to change the oxygen concentration of the outputted gas, and has the advantages of simple structure and convenient use.
Description
Technical field
This utility model relates to a kind of oxygen concentration adjusting device, and especially relating to the Wen Qiuli valve is the oxygen concentration adjusting device of sky oxygen mixing device.Belong to armarium manufacturing technology field.
Background technology
Respirator is mainly used in treatment respiratory failure patient clinically, its operation principle is to utilize the auxiliary by force patient respiration of gases at high pressure, the gas oxygen concentration height that patient sucks has a direct impact therapeutic effect, and can regulating patient, to suck the oxygen concentration of gas significant.It is adjustable that present technology is that the matched proportion density that utilizes oxygen and two kinds of gases at high pressure of air to change two kinds of gases by an empty oxygen mixing device reaches the oxygen concentration of output gas, and its precondition is that two kinds of gases at high pressure---oxygen and air must be arranged.
Summary of the invention
In order to overcome the defective that existing oxygen concentration adjusting device must use two kinds of gases at high pressure, this utility model provides a kind of oxygen concentration adjusting device, can overcome this defective effectively.
A kind of oxygen concentration adjusting device of the present utility model does not use pressure-air, only with a kind of high pressure oxygen, realizes the adjustable purpose of oxygen concentration of output gas.Scheme of the present utility model is as follows:
Oxygen concentration adjusting device is made of Wen Qiuli pipe and concentration console panel; The Wen Qiuli pipe comprises: gas access, nozzle, side mouth, gas outlet; The side mouth is positioned at the nozzle place of Wen Qiuli pipe, and the side mouth is provided with the concentration console panel, is communicated with atmosphere.The concentration console panel is provided with valve rod and splitter, and splitter is provided with pore, rotates the sectional area that splitter can be adjusted air suction inlet.Rotate splitter during rotation valve rod, thereby adjust the sectional area of air suction inlet, change the air inhalation flow.
During work, high pressure oxygen enters the Wen Qiuli pipe by the gas access, produces negative pressure during by nozzle; The air of negative pressure from side mouth suction atmosphere generates the mist of air and oxygen, and mist is exported from gas outlet.The concentration console panel is used for controlling the flow that sucks air, thereby changes the oxygen concentration of output gas.Oxygen concentration adjustable extent 37%～100%.
This utility model does not use pressure-air, only with a kind of high pressure oxygen, can change the oxygen concentration of output gas; Has advantage simple in structure, easy to use.
