Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, to help the contents of the present invention are understood.
Method used in the present invention is conventional method unless otherwise required；Used raw material and device, such as without special rule
It is fixed, it is conventional commercial product.
As shown in Fig. 1-Figure 10, the present invention provides a kind of venturi oxygen mask, including the left and right sides is provided with for solid
Determine the hangers of bungee, the oxygen outlet for being equipped with and connecting with oxygen hose is run through in mask body, it is convex that mask body is equipped with triangle
9 are played, triangular hill 9 is equipped with oxygen outlet, and oxygen hose is fixed on mask after passing through oxygen outlet by oxygen elbow nozzle 1
On ontology, the lateral wall of the oxygen elbow nozzle 1 inside mask body is equipped with first back-off 2 of circle, and the first back-off 2 is connected to
On the base station of oxygen outlet, simple and ingenious structure, oxygen hose with oxygen elbow nozzle 1 can 360 ° of rotations in mask body, can be with
Good support is provided according to the oxygen elbow nozzle 1 that needs to rotate of different situations for operation etc..
Tubular lobes card slot 4, card in tubular lobes card slot 4 are equipped in oxygen elbow nozzle 1 inside mask body
It is connected to the mushroom protrusion baffle 5 that mushroom head top is directed away from 4 side of tubular lobes card slot, the mushroom of mushroom protrusion baffle 5
Mushroom bar bottom is connected in tubular lobes card slot 4, and the lateral wall of tubular lobes card slot 4 and the inner sidewall of oxygen elbow nozzle 1 enclose
At the inlet channel 6 being connected with oxygen hose；The junction of triangular hill 9 and mask body is to mask body inside along mushroom
The direction of the mushroom head of mushroom shape protrusion baffle 5 extends to form a circle triangular cross section enclosure 7, and by mushroom protrusion baffle 5
It is trapped among in triangular cross section enclosure 7；Several perforative air are equipped in the mask body of 7 two sides of triangular cross section enclosure
Hole 8.Airport 8 in mask body is symmetric setting along the two sides of triangular cross section enclosure 7, makes to be located at mask sheet
The oxygen in internal portion and the more convenient adjusting of the mixed proportion of air, mixed effect are more preferable.In the outside of triangular cross section enclosure 7
It is installed with reinforcing rib on wall and the inner sidewall of mask body, further strengthens the firm of venturi oxygen mask structure of the invention
Property, it prolongs its service life.
As shown in figure 12, venturi oxygen mask of the invention is made of according to venturi principle, in use, oxygen passes through
The inlet channel 6 of oxygen elbow nozzle 1 enters after triangular cross section enclosure 7 by after the interception of mushroom protrusion baffle 5, reversely passes through
Behind the top interior space of triangular cross section enclosure 7, then reversely enter mask along the inner sidewall of triangular cross section enclosure 7
Body interior when entering mask body from the narrow duct of triangular cross section enclosure 7, generates negative around jet-stream wind
Pressure carries a certain amount of air from airport 8 and flows into mask body, and the size of oxygen flow changes the ratio of air and oxygen.By
Peak flow rate (PFR) and tidal volume when the air-flow spurted into mask body is greater than patient's air-breathing, it is possible to maintain concentration of oxygen inhalation
It is constant, while because the gas of high flow rate constantly rinses inside mask body, the gas of patient's exhalation is difficult to stagnant in mask body
It stays, thus substantially without repeated breathing, it needs to select venturi mask with the patient of hypercapnia in treatment hypoxemia, it can be accurate
Control oxygen concentration in ground.
Triangular hill 9 is set among mask body at upper position, and oxygen outlet is located at 9 middle position of triangular hill
Place, mushroom protrusion baffle 5 is trapped among at intermediate position by triangular cross section enclosure 7, and the mushroom that mushroom protrusion baffle 5 encloses
The edge of mushroom head is greater than the outer diameter of the inlet channel 6 of oxygen elbow nozzle 1.Such structure can preferably and human nose
Shape match, on the one hand convenient for positioning, it is easy to use, can accurately control oxygen concentration；On the other hand, it enables air to more
It is effectively quickly mixed with oxygen, plays the performance of oxygen mask more fully with comfort level；Finally also make mask sheet
The gas of internal patient's exhalation is also quickly and effectively from air air discharge.
As shown in Figure 5 and Figure 6, also interior in mask body to be embedded with breathing watch window, breathing watch window is set to three
Angular raised 9 lower section, convenient for observation.Breathing watch window includes upper cover 12 and pedestal 10 and movable peace with through-hole
Plugging sheet 11 loaded on the space interior that upper cover 12 and pedestal 10 surround.Upper cover 12 is set on the outside of mask body and edge has
Second back-off 3, pedestal 10 are set on the inside of mask body, and 10 top of pedestal is equipped with the annular projection being embedded in mask body, bottom
The fixed card slot that clamping is matched with the second back-off 3 is additionally provided on the edge of seat 10.The through-hole of pedestal 10 is equipped with the first support bar；
The through-hole of upper cover 12 is equipped with and outwardly protrudes the second support bar.Plugging sheet 11 is made of non-woven fabrics.The material of mask body is modeling
Material, organosilicon or rubber any one therein.Using venturi oxygen mask of the invention, can be breathed according to user
When open a conjunction to caused by the plugging sheet 11 in breathing watch window one and judge the breath state of user, therefore it is of the invention
Mask has small volume and less weight, can observe user's breath state in real time, and visual observation is practical reliable.
In conclusion venturi oxygen mask provided by the invention, structure is simple, easy to use, can do around oxygen outlet
The oxygen elbow nozzle 1 of 360 ° of rotations can need swivel to provide good support for operation etc. according to different situations；
Using venturi principle, the oxygen concentration in mask can be accurately controlled, safety and comfort are used；The breathing of visual observation patient
Situation, it is practical reliable.
It can be any shape the above is only the shape of the embodiment of the present invention, such as mushroom protrusion baffle 5.
In the description of the present invention, it is to be understood that, term " on ", "lower", "top", "bottom", "front", "rear", "inner",
