Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
It should be noted that, in the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are directions or positional relationships indicated on the basis of the drawings, and are only for convenience of description and simplification of description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.
As can be seen from FIG. 1, the magnitude of the flow (V) is negatively correlated to the tube diameter (A), and the magnitude of the negative pressure (P) is positively correlated to the flow. After oxygen with a certain flow passes through the jet hole with a small cross section area, the flow speed is increased to form high-speed airflow, certain negative pressure is generated, and then surrounding air is involved, and finally high-flow air-oxygen mixed airflow is formed.
As can be seen from fig. 2, the venturi device 50 is manufactured by using the above principle, and air is mixed through the two air opening adjusting ports, and further mixed with oxygen injected from the jet hole of the venturi device 50, and then high-flow air-oxygen mixed gas is output. Typically, the venturi device 50 has an oxygen flow rate of 15 liters/minute maximum.
As can be seen from fig. 3, the conventional oxygen supplying device is connected to the temperature-humidity device 40, and is connected to the venturi device 50 through the oxygen flowmeter, wherein: the oxygen pipe 31 is connected with the air inlet of the Venturi device; the air-oxygen mixing pipe 32 is connected with the air outlet of the Venturi device 50; then the patient is heated and humidified by the temperature and humidity sterilizer 40 and then connected with the heating and humidifying breathing pipeline to be connected with the nasal obstruction to provide oxygen for the patient.
As can be seen in fig. 4-6, the high flow oxygen therapy regulating device comprises an oxygen receiving sleeve 10 and a regulating sleeve 20; one end of the oxygen receiving sleeve 10 is provided with an oxygen receiving hole 11, and the other end is provided with a first sleeving hole 12; the oxygen-contacting hole 11 is communicated with the first sleeve hole 12, and the inner diameter of the first sleeve hole is larger than that of the oxygen-contacting hole. Since the diameter of the oxygen-contacting hole 11 is smaller than that of the first connection hole 12, the flow rate of oxygen entering the oxygen-contacting sleeve 10 is slowed down.
One end of the adjusting sleeve 20 is provided with a second sleeving hole 21, the other end is provided with a third sleeving hole 22, and the inner diameter of the third sleeving hole 22 is larger than that of the second sleeving hole 21; an interface 23 is arranged at the junction of the second casing hole 21 and the third casing hole 22, an inner through pipe 24 extending towards the third casing hole 22 is arranged on the interface 23, and the length of the inner through pipe 24 is smaller than that of the third casing hole 22; the outer diameter of the first registration hole 12 is detachably connected to the second registration hole 21. When the oxygen reaches the second sleeving hole 21, the oxygen enters the inner through pipe 24, and the flow rate of the oxygen is increased at the moment because the aperture of the inner through pipe 24 is smaller than that of the second sleeving pipe 21; so that the flow rate of oxygen out of the third socket hole 22 may be greater than 15 liters/minute; further, the oxygen can be buffered in the third socket hole 22, and since the flow rate in the oxygen-receiving socket is small, the separation of the oxygen tube from the high-flow oxygen therapy adjusting device does not occur.
Further, the outer diameter of the first staking hole 12 is the same as the inner diameter of the second staking hole 21. At this time, the first splicing hole 12 can be inserted into the second splicing hole 21, so that the outer wall of the first splicing hole 12 is attached to the inner wall of the second splicing hole 21, and then the first splicing hole 12 and the second splicing hole 21 can be spliced and connected by rotating forcibly.
Another way of engaging the first and second engagement holes 12 and 21 is: the internal diameter of the first socket hole 12 is the same as the external diameter of the second socket hole 21, and at this time, the second socket hole 21 can be inserted into the first socket hole 12, so that the outer wall of the second socket hole 21 is attached to the inner wall of the first socket hole 12, and then the first socket hole 12 and the second socket hole 21 are connected in a sleeved mode through forced rotation and clamping.
Further, an external thread 12a is disposed on the outer wall of the first coupling hole 12, and an internal thread 21a matched with the external thread 12a is disposed on the inner wall of the second coupling hole 21. In addition, the first and second staking holes 12 and 21 are provided with internal threads 21a on the inner wall of the first staking hole 12 and external threads 12a on the outer wall of the second staking hole 21 that mate with the internal threads 21 a. Through setting up to the helicitic texture on first box hole 12 and the second box hole 21, also can make things convenient for this high flow oxygen therapy adjusting device to dismantle the equipment.
Since the first and second registration holes 12 and 21 are provided in a detachable form, it is convenient for the doctor to wash and sterilize the device.
Further, an air tube 25 communicated with the third sleeving hole 22 is arranged on the wall of the third sleeving hole 22, a blocking cap 26 is arranged at the tail end of the air tube 25, and the blocking cap 26 can be buckled with the tube opening of the air tube 25. By arranging the air pipe 25 and the blocking cap 26, air can enter the third sleeving hole 22, and air-oxygen mixed gas can be obtained; when air is not required to enter the third sleeving hole 22, the blocking cap 26 is buckled at the tail end of the air pipe 25 to achieve the purpose.
Further, in order to control the flow rate of air flowing into the third regulation hole 22, a flow rate regulator 27 is provided on the air pipe 25; the flow rate regulator 27 may employ a regulating valve or a regulating clamp. The flow rate of air into the third socket bore 22 can be controlled by a regulating valve or clamp.
