Description
Technical Field
The utility model belongs to the technical field of clinical medical instrument and specifically relates to a novel oxygen tube check valve structure.
Background
Currently, the current state of the art commonly used in the industry is such that: oxygen therapy is to use various methods to make the oxygen concentration in the inhaled gas of a patient higher than atmospheric concentration so as to increase the oxygen partial pressure in alveoli, improve the symptoms of hypoxia and correct hypoxemia. Oxygen therapy is not only a common technical operation, but also an emergency treatment measure for rescuing patients with acute diseases. In clinical work it was found that the effectiveness of oxygen therapy is not only dependent on the oxygen uptake concentration. The concentration and type of oxygen deficiency depend on the oxygen uptake route and the oxygen uptake mode. The existing oxygen inhalation methods mainly comprise two methods, one is a traditional nasal obstruction type oxygen inhalation method; the one is mask type oxygen inhalation mode, no matter whether patient breathes or inhales, oxygen all lasts large-traffic supply through the oxygen uptake pipeline, and oxygen is extravagant great, can lead to oxygen concentration in the local space air to increase moreover, forms the potential safety hazard, and nasal insert type oxygen inhalation method needs patient's nasal cavity to breathe in the oral cavity and exhale, uses the oxygen tube for a long time and can make patient's throat dry and mute discomfort, provides a novel oxygen tube check valve structure now and solves above-mentioned problem.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the prior art, the utility model provides a novel oxygen tube one-way valve structure.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a novel oxygen tube check valve structure, includes the valve body, the oxygen tube is connected in the valve body left side, establish first check valve between oxygen tube and valve body, the oxygen tube is connected out to the valve body below, establish the one-way valve of second between oxygen tube and valve body, the breathing pipe is connected to the valve body top, establish the one-way valve of third between breathing pipe and valve body, the outlet duct is connected to breathing pipe one side, the fourth check valve is established to outlet duct and breathing intertube.
Foretell novel oxygen tube check valve structure, oxygen inlet pipe left end is connected the apparatus of oxygen suppliment.
The novel oxygen tube one-way valve structure is characterized in that the air storage bag is connected below the oxygen outlet tube.
The beneficial effects of the utility model are that, the utility model are simple in structure, and convenient in design, the patient is connected to the breathing pipe, advance the oxygen pipe to the valve body oxygen suppliment of check valve structure, when the patient breathes in, breathing pipe department atmospheric pressure reduces, third check valve is opened, oxygen flow direction patient, when the patient exhales, breathing pipe department pressure increase, the one-way valve of third is closed, the one-way valve of second is opened, the oxygen that flows into the valve body flows into the gas storage bag through going out the oxygen pipe by the one-way valve of second, avoid oxygen extravagant, the waste gas of patient's exhalation can not get into the gas storage bag, because third check valve is closed, waste gas is discharged through the outlet duct by fourth check valve, the patient can breathe in and exhale with the nasal cavity simultaneously, avoid long-term use.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, 1, a valve body, 2, an oxygen inlet pipe, 3, a first one-way valve, 4, an oxygen outlet pipe, 5, a second one-way valve, 6, an oxygen absorption pipe, 7, a third one-way valve, 8, an air outlet pipe and 9, a fourth one-way valve are arranged.
Detailed Description
