Detailed Description
For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings 1-4 and the accompanying examples.
Example 1
Combine attached 1 and 2, the nasal oxygen tube with function of taking a breath of this embodiment, include nasal oxygen tube body 1 and locate two on the nasal oxygen tube body 1 and advance nasal tube 2, nasal oxygen tube body 1 and the intercommunication of advancing nasal tube 2, 1 both ends of nasal oxygen tube body are equipped with air inlet 11 and gas outlet 12 respectively, air inlet 11 and 12 departments of gas outlet install check valve 3, and the check valve 3 of air inlet 11 sets to allow gas to get into nasal oxygen tube body 1 through this check valve 3 in, and the check valve 3 of gas outlet 12 sets to allow the gas in the nasal oxygen tube body 1 to outwards discharge through check valve 3.
When a patient inhales, the pressure in the nasal oxygen tube body 1 is reduced, the one-way valve 3 of the air inlet 11 is opened so that oxygen can enter the nasal oxygen tube body 1 through the one-way valve 3, the oxygen enters the nasal oxygen tube body 1 and then enters the nasal cavity of the patient through the nasal inlet tube 2 for breathing, when the patient exhales, air exhaled from the nasal cavity enters the nasal oxygen tube body 1, the pressure in the nasal oxygen tube body 1 is increased so as to open the one-way valve 3 of the air outlet 12, and the exhaled air can be discharged outwards through the one-way valve 3; by adopting the structure, the nasal oxygen tube has the ventilation function, the exhaled gas can not pollute the subsequently inhaled oxygen, and the concentration of oxygen supply is ensured while the ventilation purpose is realized.
As an alternative of the present embodiment, the nose inlet pipe 2 and the nose oxygen pipe body 1 have an inclination angle, and the nose inlet pipe 2 is inclined to the direction of the other nose inlet pipe 2 by a certain angle; adopt above-mentioned structural design for it accords with human nasal cavity structure more to advance nasal tube 2 when using, according to the principle of anthropology, improves the comfort level when the patient uses the nasal oxygen tube.
As an alternative of the present embodiment, the nose inlet tube 2 is sleeved with a slip-off preventing ring 21, and the slip-off preventing ring 21 is an annular protrusion integrally formed on the outer wall of the nose inlet tube 2; the anti-slip ring 21 can reduce the risk that the nasal tube 2 falls from the nasal cavity of the patient, and meanwhile, the anti-slip ring 21 effectively avoids the problem that the nasal plug extends into the nasal cavity of the patient for too long time, so that the nasal plug damages the nasal mucosa of the patient and causes cross infection, so that the nasal plug can be used for oxygen delivery of the patient, the patient cannot be injured, and the use is convenient.
As an alternative of the embodiment, a sealing tape is wrapped at the joint of the nasal oxygen tube body 1 and the nasal inlet tube 2; the sealing tape can prevent the junction of the nasal oxygen tube body 1 and the nasal inlet tube 2 from oxygen leakage, improve the utilization rate of oxygen and ensure that the patient obtains sufficient oxygen supply.
As an alternative to this embodiment, the air inlet 11 and air outlet 12 are different sizes; the purpose of adopting the above structural design is to prevent misconnection, and an operator can distinguish the air inlet 11 from the air outlet 12 conveniently.
In this embodiment, the inner diameters and the outer diameters of the air inlet 11 and the air outlet 12 are different, the inner diameters are different, so that an operator can determine whether to misconnect according to whether the operator can install the air inlet and the air outlet 12, and the outer diameters are different, so that the operator can directly distinguish the air inlet 11 and the air outlet 12 through naked eyes, thereby improving the speed during assembly.
As the alternative of this embodiment, the both ends of nasal oxygen cannula body 1 all are connected with bellows 4, and bellows 4 and nasal oxygen cannula body 1's tip are through the mode fixed connection of pegging graft, compare the hose, and bellows 4 has certain effect of preventing buckling, and the stable supply of oxygen when guaranteeing the oxygen suppliment.
Example 2
With reference to fig. 1-4, in the nasal oxygen cannula with ventilation function of this embodiment, compared with embodiment 1, the check valve 3 includes a fixing bracket 31 and a membrane 32 disposed on one side of the fixing bracket 31, the fixing bracket 31 and the membrane 32 are connected by a connecting structure, and under the action of air pressure, the membrane 32 can be flushed away in a direction opposite to the fixing bracket 31 to be in an open state.
In this embodiment, connection structure locates the edge of fixed bolster 31, connection structure is including locating the through-hole 311 of fixed bolster 31 edge and locating diaphragm 32 edge and through-hole 311 matched with bolt 321, can realize the fixed connection of fixed bolster 31 and diaphragm 32 in inserting into through-hole 311 through corresponding with bolt 321, because connection structure locates the edge of fixed bolster 31, when diaphragm 32 outwards flicks under the effect of atmospheric pressure, the clearance between diaphragm 32 and the fixed bolster 31 is bigger when connection structure locates the axle center department of fixed bolster 31, thereby guarantee gaseous instantaneous throughput, can realize more large-traffic gas flow in the same time.
