Detailed Description
In the following detailed description of the embodiments, reference is made to the accompanying drawings, which form a part hereof. The drawings show, by way of example, specific embodiments in which the invention may be practiced. The embodiments shown are not intended to be exhaustive of all embodiments according to the invention. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. With respect to the drawings, directional terminology, such as "lower," "upper," "left," "right," etc., is used with reference to the orientation of the drawings as described. Because components of embodiments of the present invention can be implemented in a variety of orientations, the directional terminology is used for purposes of illustration and is in no way limiting. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.
Referring to fig. 1-8, an object of the present invention is to provide an oxygen mask body 18, the oxygen mask body 18 comprising a mask body 1, a face-fitting edge 2 and an oxygen guiding cylinder 3, wherein the mask body 1 comprises a breathing cavity and an oronasal region configured to correspond to the oronasal region of a wearer, the face-fitting edge 2 is disposed at the peripheral edge of the mask body 1 to fit the facial contour of the wearer in use, the oxygen guiding cylinder 3 is disposed on the oronasal region, the oxygen guiding cylinder 3 comprises an air inlet end 4, an air outlet end 5 and an oxygen delivery passage section 6 between the air inlet end 4 and the air outlet end 5, the air inlet end 4 is configured to be capable of being mounted with an oxygen connector 7, the air outlet end 5 is in communication with the breathing cavity, and the volume of the oxygen guiding cylinder 3 is 2000mm3-16000mm3。
In the oxygen mask body 18, the volume of the oxygen guide tube 3 is 2000mm3-16000mm3By means of the volume of the oxygen guide cylinder, the time required for the oxygen concentration in the oxygen guide cylinder to rise to the effective concentration is short while the oxygen flow rate is reduced, the level of the inhaled oxygen concentration is kept stable, the oxygen concentration is sufficient, and even if the breathing frequency and the oxygen flow rate of a wearer change, the oxygen mask body can still ensure the effective and stable oxygen inhalation concentration and ensure the oxygen inhalation treatment effect.
In addition, the oxygen mask body 18 of the present application also has significant clinical significance in attenuating the intensity of oxygen flow directly to the oronasal region of the wearer. Because the nasal mucosa of a human body can continuously secrete water to moisten inhaled air when breathing, the nasal cavity can not be dried. The excessive oxygen flow intensity directly flowing to the mouth and nose area of the wearer can directly take away a large amount of moisture of nasal mucosa when the nasal mask is inhaled, so that the nasal cavity of the wearer is dry and uncomfortable. The utility model provides an oxygen mask body 18 is because can effectively weaken the oxygen flow strength that directly flows to the person's of wearing mouth nose region to can reduce the air current oppression sense of oxygen by showing, consequently, can avoid directly taking away the moisture of nasal cavity mucous membrane secretion objectively, thereby make the person's of wearing nasal cavity remain good mucous membrane moisture all the time and come the moist air of inhaling, promote the comfort level of treatment.
Note that, in the oxygen mask body, when the thickness of the wall of the oxygen conduit 3 is relatively thin and is ignored, the volume of the oxygen conduit 3 is the volume of the oxygen conduit 3.
In the oxygen mask body 18, in some embodiments, the air outlet end 5 of the oxygen guiding cylinder 3 may protrude from the inner surface 9 of the mask wall in the oronasal region by a predetermined distance, and the predetermined distance may be selected according to actual requirements.
Alternatively, in some embodiments, the outlet end 5 is attached to the oronasal region, and the nozzle rim 8 of the outlet end 5 is lower than or flush with the inner surface 9 of the mask wall in the oronasal region over the entire circumference of the nozzle. This allows oxygen flowing at the peripheral region within the oxygen guiding cylinder 3 to continue to flow peripherally along the inner face of the mask wall in the oronasal region at the rim of the mouth of the outlet 5 for diffusion. Thus, in practical use, when oxygen enters the oxygen guiding cylinder 3 through the oxygen connector and flows along the oxygen guiding cylinder 3, and when oxygen in the peripheral area of the oxygen guiding cylinder 3 flows to the rim of the mouth of the air outlet end 5 along the oxygen guiding cylinder 3, the oxygen diffuses all around and continues to flow along the inner surface 9 of the mask wall in the mouth-nose area to diffuse, and finally forms an oxygen ring substantially surrounding the mouth-nose area of the wearer, which can effectively weaken the intensity of oxygen flow directly flowing to the mouth-nose area of the wearer, thereby remarkably reducing the airflow oppression of the oxygen, enabling the oxygen to uniformly diffuse in the mouth-nose area and the peripheral area of the wearer, avoiding discomfort such as nasal cavity dryness and headache, and improving the comfort level of the wearer.
In addition, the oxygen mask body 18 of this application still very is favorable to the carbon dioxide of wearer's exhalation to be discharged fast, avoids carbon dioxide to remain in the oxygen mask body. In the existing oxygen mask, a plurality of retention areas exist in the mask body, so that a part of carbon dioxide exhaled by a patient can enter and remain in the retention areas and is difficult to discharge, and when the patient inhales, the patient can directly inhale the carbon dioxide repeatedly, which is particularly unfavorable for the patient, especially a critically ill patient. Since repeated inhalation of carbon dioxide directly leads to increased heart rate and increased respiratory rate, in some patients with serious illness, carbon dioxide retention may also be caused, which disturbs the human body's internal environment and thus affects the blood pH, and respiratory acidosis may be caused, thus affecting the treatment. In the oxygen mask body 18 of the present application, the edge of the nozzle at the air outlet end is lower than or even with the inner surface of the mask wall in the oral-nasal region in the whole circle direction, so that the occurrence of a carbon dioxide retention area in the mask body can be completely avoided, and the carbon dioxide exhaled by the wearer can not be retained, which can completely avoid the repeated inhalation of carbon dioxide, thereby having more important clinical treatment effect, especially for critically ill patients.
In addition, in the oxygen mask body, in some embodiments, the included angle between the inner surface of the edge of the nozzle edge and the inner surface of the mask wall can be 180 degrees to form a flush transition connection, or the included angle between the inner surface of the edge of the nozzle edge and the inner surface of the mask wall can be 180 degrees to 270 degrees to form a non-flush transition connection, and the flush transition connection or the non-flush transition connection can allow oxygen in the peripheral area in the oxygen guide cylinder to diffuse around when flowing along the oxygen guide cylinder to the nozzle edge of the air outlet end and flow along the inner surface of the mask wall in the oral-nasal area to continue diffusion.
In other embodiments, in order to improve the smoothness of the air flow while adapting to the extended contour of the mask body 1, referring to fig. 2, the inner surface of the rim of the mouthpiece rim 8 is smoothly connected to the inner surface of the mask wall through an arc surface protruding toward the breathing chamber in the entire circumferential direction, so that the oxygen in the peripheral region of the oxygen guide tube smoothly and smoothly flows through the arc surface at the mouthpiece rim 8 by the arc surface, smoothly flows onto the inner surface of the mask wall in the oronasal region while changing the direction to diffuse all around, and continues to flow to continue diffusion. Thus, the arc-shaped surface between the rim inner surface of the nozzle rim 8 and the mask wall inner surface can allow the oxygen flow to smoothly flow from the rim inner surface to the mask wall inner surface. Of course, the curvature of the arc-shaped surface can be specifically selected according to actual requirements.
In addition, in order to further improve the stability of oxygen inhalation concentration and ensure the oxygen inhalation therapeutic effect, in some embodiments, the tube mouth area of the air outlet end 5 is 200mm2-1200mm2. By such a tube mouth area, it is possible to form an appropriate oxygen region at the oronasal region of the wearer while combining the volume of the oxygen guide tube 3 of 2000mm3-16000mm3Since the time required for raising the oxygen concentration in the oxygen guide tube to the effective concentration is further shortened, the level of the inhaled oxygen concentration is maintained stable and the oxygen concentration is sufficient, even if the breathing frequency and the oxygen flow rate of the wearer change, the oxygen mask body 18 can further ensure the effective and stable oxygen inhalation concentration and ensure the oxygen inhalation therapeutic effect.
In addition, in one embodiment, the area of the mouth of the air outlet end 5 of the oxygen guiding cylinder 3 is 200mm2-1200mm2The volume of the oxygen guide cylinder 3 is 2000mm3-16000mm3By such a mouthpiece area, a volume of the oxygen guiding canister 3, and a mouthpiece edge of the air outlet end 5 being lower than or equal to the mask wall inner surface 9 of the oronasal region in the entire circle direction, even if the breathing frequency and the oxygen flow rate of the wearer change, the oxygen mask body 18 can ensure an effective and stable oxygen inhalation concentration, ensure an oxygen inhalation therapeutic effect, and allow oxygen flowing in the peripheral region inside the oxygen guiding canister 3 to continue to flow around along the mask wall inner surface of the oronasal region at the mouthpiece edge of the air outlet end 5 to be diffused. Thus, it isIn practical use, oxygen enters the oxygen guiding cylinder 3 through the oxygen connector and flows along the oxygen guiding cylinder 3, and when oxygen in the peripheral region of the oxygen guiding cylinder 3 flows to the cylinder mouth edge of the air outlet end 5 along the oxygen guiding cylinder 3, the oxygen diffuses around and continues to flow along the inner surface 9 of the mask wall in the oral-nasal region to diffuse, and finally an oxygen ring substantially surrounding the oral-nasal region of the wearer is formed, so that the oxygen flow strength directly flowing to the oral-nasal region of the wearer can be effectively weakened, the airflow pressure sense of the oxygen can be remarkably reduced, the oxygen can be uniformly diffused in the oral-nasal region of the wearer and the peripheral region thereof, and the use comfort of the wearer is improved.
In addition, in order to further improve the stability of the oxygen concentration and ensure the therapeutic effect of oxygen inhalation, so that the time required for the oxygen concentration in the oxygen guide cylinder to rise to the effective concentration is kept, the oxygen concentration level is maintained, and the maximum oxygen concentration level reaches the better effect, in some embodiments, the cylinder mouth area of the air outlet end 5 is 240mm2-1120mm2The volume of the oxygen guide cylinder 3 is 2200mm3-15000mm3. In order to maintain the inhaled oxygen concentration level for the time required for the oxygen concentration in the oxygen guiding cylinder to rise to the effective concentration and achieve the most effective inhaled oxygen concentration level, in some preferred embodiments, the cylinder mouth area of the air outlet end 5 is 300mm2-1000mm2The volume of the oxygen guide cylinder 3 is 3000mm3-13000mm3. In order to maintain the intake oxygen concentration level for the time required for the oxygen concentration in the oxygen guiding cylinder to rise to the effective concentration and the maximum intake oxygen concentration level for the optimum effect, in some further preferred embodiments, the cylinder opening area of the gas outlet end 5 is 400mm2-650mm2The volume of the oxygen guide cylinder 3 is 4100mm3-7700mm3。
In addition, it should be noted that the thickness is 200mm2-1200mm2Meanwhile, the area of the opening of the air outlet end 5 can be any value, for example, see the specific values in table 1 below (the area size is from the first row to the left, then from the second row to the left, then from the third row to the left).
TABLE 1
In addition, it should be noted that the thickness is 2000mm3-16000mm3The volume of the oxygen guiding cylinder 3 may be any value, for example, see the specific values in table 2 below (the volume is from the first row to the left, then the second row to the left, then the third row to the left).
TABLE 2
In addition, in some embodiments, referring to fig. 1, a nose avoidance opening (not shown) is formed in a nose corresponding region 10 of the mask body 1 for corresponding to the nose of the wearer, and extends to the mouthpiece edge 8 of the air outlet end 5 or at a predetermined distance from the mouthpiece edge 8 of the air outlet end 5, for example, the nose avoidance opening extends to the upper mouthpiece edge 11 of the mouthpiece edge 8 or at a predetermined distance from the upper mouthpiece edge 11. Therefore, the nose of the wearer can be prevented from touching the mask body 1, and the wearing comfort is improved. For example, in the oxygen mask body shown in fig. 1, since the nose corresponding region 10 extends in a direction away from the face, the nose corresponding region 10 may not be formed with a nose avoidance opening, or may be formed with a nose avoidance opening. For another example, in the oxygen mask body shown in fig. 4, since the connecting line L can be rotated clockwise with respect to the reference horizontal plane of 0 °, the nose corresponding region 10 extends in the direction toward the face, and at this time, a nose avoiding opening may be formed in the nose corresponding region 10, and of course, the nose corresponding region 10 may not be formed with a nose avoiding opening.
In addition, in the oxygen mask body 18, the cross-sectional shape of the oxygen guiding cylinder 3 such as the oxygen delivery passage section 6 may have various forms, but it should be noted that, regardless of the form of the cross-sectional shape of the oxygen guiding cylinder 3, it is sufficient that the area of the opening of the outlet end 5 is 200mm2-1200mm2And the volume of the oxygen guide cylinder 3 is 2000mm3-16000mm3And (4) finishing. For example, in some embodiments, no matter what the cross-sectional shape of the oxygen guiding cylinder 3 is, it is sufficient that the area of the cylinder opening of the gas outlet end 5 is 200mm2-1200mm2And the volume of the oxygen guide cylinder 3 is 2000mm3-16000mm3And (4) finishing. For example, in some embodiments, the cross-sectional shape of the oxygen guiding cylinder 3 is a polygon, and the polygon may be a triangle, a square (refer to fig. 1 and 3), a rectangle, a trapezoid, a pentagon, a hexagon, or the like. For example, in some other embodiments, the oxygen guide 3 has a circular cross-sectional shape, see fig. 5 and 6. For another example, in some other embodiments, the cross-sectional shape of the oxygen guide 3 is elliptical. For another example, in some other embodiments, the cross-sectional shape of the oxygen guiding cylinder 3 includes a protruding section 13 protruding radially toward the inside of the oxygen guiding cylinder, for example, the cross-sectional shape of the oxygen guiding cylinder 3 is a quincunx shape or a pentagonal shape (refer to fig. 7 and 8). Of course, the cross-sectional shape of the oxygen guiding cylinder 3 may also be other shapes.
In addition, in some embodiments, the cross-sectional dimension of at least a part of the oxygen guiding cylinder 3, such as the oxygen delivery channel section 6, is gradually enlarged in the direction from the air inlet end 4 to the air outlet end 5, so that the cross-sectional dimension is gradually enlarged, thereby further slowing down the oxygen flow rate while ensuring the oxygen concentration, reducing the sense of oppression of the air flow, enabling the oxygen to be uniformly diffused in the nose and mouth of the wearer and the surrounding area thereof, thereby ensuring the oxygen inhalation therapy effect and improving the comfort level of the wearer. In addition, in some embodiments, the entire length of the oxygen guiding cylinder 3 in the axial direction is gradually expanded in the direction from the gas inlet end 4 to the gas outlet end 5. In addition, in an alternative embodiment, the cross-sectional dimension of the oxygen guide cylinder 3 may be changed in a stepwise manner in the axial direction. In addition, in some embodiments, the oxygen guide cylinder 3 may be an equal diameter cylinder, that is, the inner diameter of the oxygen guide cylinder 3 is the same from the gas inlet end to the gas outlet end.
In addition, referring to fig. 1, the transition area of the mask body 1 between the oronasal area and the face engaging edge 2 is provided with an air permeable structure. The ventilation structure can allow the exhaled air of the wearer to be exhausted to the external environment, and in addition, air in the external environment is also allowed to enter the breathing cavity, so that the wearer can have the feeling similar to natural breathing when wearing the oxygen mask body, and the feeling of respiratory urgency is not generated.
Of course, the air-permeable structure may have various types, for example, in one type of the air-permeable structure, the air-permeable structure may be a plurality of air holes formed in a part of the transition region in a gathering manner, and of course, the number, size and shape of the air holes may be set according to actual requirements. Alternatively, in another type of the air permeable structure, referring to fig. 1 and 2, the air permeable structure includes a plurality of open openings 14 arranged at intervals in the circumferential direction of the mask body 1, the plurality of open openings 14 are sized such that the transition region between the adjacent open openings 14 is formed as a connecting strip 15, and a reinforcing rib 16 extending between the oxygen guide tube 3 and the face attaching edge 2 is formed on the inner surface of the connecting strip 15, for example, extending from the oxygen guide tube 3 to the face attaching edge 2. That is, the open openings 14 may have a larger size, and the number and shape of the open openings 14 may be set according to the requirement, for example, the number of the open openings 14 may be 3, 4 or 5, and the shape may be a circular hole, a square hole or an elliptical hole, for example, the shape of each open opening 14 may be as shown in fig. 1 and 2. The open mouth 14 may allow the wearer to speak and drink naturally. For example, the open opening 14 under the mask body 1 may allow the wearer to drink directly from a cup, or alternatively, may allow a straw to pass through, allowing the wearer to drink through the straw.
In addition, in the oxygen mask body 18, the oxygen mask body 18 may be made of a soft material, so that the oxygen mask body 18 may be deformed to adapt to the face shape change of different wearers. Alternatively, the oxygen mask body 18 may be made of a hard material, and in this case, the face engaging edge 3 may have flexibility so as to be more suitable for being worn by different wearers, and the soft face engaging edge 2 may adapt to the face shape change of different wearers.
Furthermore, another object of the present invention is to provide an oxygen mask, which comprises an oxygen connector 7 (refer to fig. 9 and 10) and an oxygen mask body 18 as described in any of the above, wherein the oxygen connector 7 comprises a connector 19 and a baffle 20, the connector 19 comprises an oxygen inlet channel 21, the baffle 20 comprises a baffle surface 22, the baffle surface 22 can be a concave baffle surface or a convex baffle surface, the baffle 20 is connected to an outlet of the oxygen inlet channel 21, the baffle surface 22 faces an outlet of the oxygen inlet channel 21, the connector 19 can be rotatably mounted on the air inlet 4, for example, a section of a cylinder of the connector 19 can be rotatably mounted in a mounting hole 23 of the air inlet 4, and the outlet of the oxygen inlet channel 21 and the baffle 20 are located in the oxygen guiding cylinder 3.
In the oxygen mask, since the baffle cover 20 of the oxygen connector 7 has the baffle surface 22, the baffle cover 20 is connected at the outlet of the oxygen inlet passage 21 and the baffle surface 22 faces the outlet of the oxygen inlet passage 21, and the outlet of the oxygen inlet passage 21 and the baffle cover 20 are positioned in the oxygen guiding cylinder 3, which can make the oxygen flow flowing out from the outlet of the oxygen inlet passage 21 contact the baffle surface 22, the baffle surface 22 can diffuse the oxygen flow to the surrounding by using its own baffle surface shape to weaken the oxygen flow strength, so that the oxygen flow flows into the oxygen guiding cylinder 3 from the surrounding of the baffle surface and mainly flows forward in the surrounding area of the oxygen guiding cylinder 3, thus, as mentioned above, the oxygen mask can still ensure effective and stable oxygen inhalation concentration when the breathing frequency and oxygen flow rate of the wearer change, and can also remarkably reduce the flow sense of the oxygen, so that the oxygen can be uniformly diffused in the mouth and the surrounding area of the wearer, thereby ensuring the oxygen inhalation therapy effect and improving the comfort level of the wearer.
In addition, in the oxygen mask, the shape of the baffle 20 may be an umbrella shape, or may be a bowl shape, and the cross section may be a circular shape, or may be a polygonal shape. In addition, the baffle concave surface of the baffle housing 20 may not be provided with any baffle plate, and referring to fig. 10, a baffle space is formed between adjacent baffle plates. Thus, after contacting the concave baffle surface, the oxygen flow is divided into a plurality of smaller oxygen flows baffled in the baffle space by the plurality of baffle plates, and the plurality of smaller oxygen flows flow to the edge along the baffle space and enter the peripheral area of the oxygen guide cylinder, so that the baffle plates can fully disperse the oxygen flow entering through the oxygen inlet channel to further weaken the intensity of the oxygen flow. In addition, a plurality of baffle plates can be uniformly distributed at circumferential intervals or non-uniformly distributed.
In addition, in the oxygen mask, the oxygen joint may have various types.
