Abstract
Provided is a coordinated typed oxygen-supply device to control the oxygen quantity according to the feedback oxygen with controlling rods and pulling rods. An elastic gasbag is additionally fixed on the lower portion of the oxygen controlling valve. The real end of the valve pin is connected with the pulling rod, and the pulling rod is vertically arranged between the oxygen controlling valve and the elastic gasbag. The upper and lower ends of the elastic gasbag are provided with upper and lower controlling rods. The junction can rotate around the shaft and is connected with the inside wall of the elastic gasbag, and the lower controlling rod is connected to the pallet arranged at the end portion of the puling rod. Oxygen is employed as the motor source to adjust the supply according to the oxygen absorbed quantity of the patients, thereby enabling the oxygen absorbing to be more approximate to the feelings of normal breathing. The utility model also has the advantages of simple structure, reasonable design and stable property, besides the device can not be influenced by the pressure changes of oxygen source.
Description
This utility model relates to a kind of device that utilizes oxygen to realize oxygen supply as power source, feedback control pull bar linked system.
Existing apparatus of oxygen supply though structure has nothing in common with each other, all is a negative pressure of utilizing air-breathing generation after all, and the oxygen uptake passage is opened in the motion of control oxygen uptake valve, realizes the purpose of oxygen uptake.These are referred to as lung formula oxygen supply by the device of air-breathing generation negative pressure realization oxygen supply.This class device in use, not only be subjected to varying in size of vital capacity to influence the size of negative pressure, and the pressure of source of oxygen is high more, it is big more to open the needed negative pressure numerical value of oxygen uptake valve, and the functional reliability of oxygen uptake valve is also just poor more, and the result causes the deficiency of oxygen quantity delivered in the oxygen uptake process, oxygen therapic patient sensation oxygen uptake resistance is increased, the oxygen uptake effort, even cause intermittently oxygen uptake, influence therapeutic effect.
The purpose of this utility model is to provide a kind of makes oxygen uptake more approach air-breathing at ordinary times sensation, can according to how many adjusting supplies automatically of oxygen absorbed, and the oxygen uptake resistance is little, the oxygen feedback control pull bar coordinated type apparatus of oxygen supply of stable performance.
For achieving the above object, the technical scheme that this utility model is taked is: this oxygen feedback control pull bar coordinated type apparatus of oxygen supply, comprise oxygen absorption mask, oxygen control valve etc., the below that it is characterized in that oxygen control valve has additional and oxygen control valve, the elastic bag that oxygen absorption mask is communicated with, the needle of oxygen control valve is terminal to link with pull bar, pull bar is vertically set among oxygen control valve and the elastic bag, the pull bar lower end that is positioned at elastic bag is provided with, lower control arm, on, the junction of lower control arm can rotate around the axis, and link to each other with the inwall of elastic bag, lower control arm links to each other with the pallet of pull bar end.
Above-mentioned apparatus of oxygen supply has changed traditional oxygen uptake mode of operation, has realized utilizing oxygen to realize the purpose of oxygen supply as power source, feedback control pull bar linked system.The unlatching of oxygen uptake valve is no longer controlled by the vacuum magnitude of the air-breathing generation of patient, but by how many automatically adjusting supplies of device according to patient's oxygen absorbed itself.The oxygen of patient respiratory, that directly gets is stored in oxygen in the oxygen capsule, has overcome in traditional inhalation device, and each oxygen of breathing all needs the oxygen uptake resistance that action caused through a plurality of controlling units, makes oxygen uptake more approach air-breathing at ordinary times sensation.Especially wait the patient who carries out hyperbaric oxygentherapy to getting old and weak, better oxygen uptake instrument is provided.According to GB regulation, the oxygen uptake resistance of medical hyperbaric oxygen chamber 〉=-400Mpa, and in the reality oxygen uptake resistance of conventional apparatus generally all≤-400Mpa, the influence that changed by source of oxygen pressure.After testing, the oxygen uptake resistance of this device 〉=-1OMpa, stable performance, and the influence that not changed by source of oxygen pressure.This installs advanced design, and is scientific and reasonable, simple in structure, is easy to promote, and changes a little on existing apparatus of oxygen supply and can realize that this device can be widely used in hyperbaric oxygen chamber and common oxygen inhalation therapy.
Accompanying drawing is the structural representation of this utility model embodiment.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof:
Among the figure: the 1-oxygen absorption mask; 2-one-way control valve sheet; The 3-rubber balloon; The 4-pull bar; The 5-needle; The 6-sealing gasket; The 7-oxygen control valve; The last control stick of 8-; The 9-lower control arm; The junction point of 10-control stick and air bag inwall; The 11-pallet; The 12-spring.
As shown in the figure, this oxygen feedback control pull bar coordinated type apparatus of oxygen supply comprises oxygen absorption mask 1, oxygen control valve 7 etc., and needle 5, sealing gasket 6 and spring 12 etc. in the oxygen control valve 7 are prior art.Main improve be in: below oxygen control valve 7, set up the rubber balloon 3 that is communicated with oxygen control valve 7, oxygen absorption mask 1, needle 5 ends of oxygen control valve 7 link with pull bar 4, pull bar 4 is vertically set among oxygen control valve 7 and the rubber balloon 3, the lower end that is positioned at the pull bar 4 of rubber balloon 3 is provided with upper and lower control stick 8,9, the junction of upper and lower control stick 8,9 can rotate around the axis and links to each other with the inwall of rubber balloon 3, and lower control arm 9 links to each other with the pallet 11 of pull bar 4 ends.
It is air-breathing that the patient puts on oxygen absorption mask 1, one-way control valve sheet 2 is opened, oxygen in the rubber balloon 3 reduces, rubber balloon 3 lax contractions, pull bar 4 is because own wt produces the gravity that moves downward, thereby the end that drives the needle 5 that links to each other with it moves downward, and sealing gasket 6 is opened, and oxygen flows in the rubber balloon 3 by oxygen control valve 7.Oxygen uptake stops, and during expiration, one-way control valve sheet 2 is closed.Continue to flow in the rubber balloon 3 greater than the oxygen about pressure 0.3Mpa in the air bag, inflow along with oxygen, rubber balloon 3 beginning expanding volumes increase, the junction point 1O of last lower control arm 8,9 and air bag 3 inwalls is gradually to the both sides horizontal open, pallet 11 pushing drawing rods 4 move upward, and the end of needle 5 moves upward, under needle 5, sealing gasket 6 and spring 12 synergy, make oxygen control valve 7 recover closed condition, oxygen stops to flow in the rubber balloon 3.
