Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a positive pressure ventilation nasal mask. Background Art

[0002] Most of the existing positive pressure ventilation nasal masks are composed of a nasal mask body equipped with a headband, which is used to fix the position of the nasal mask body on the user's face, and the headband is made of a fabric composite.

[0003] However, the existing positive pressure ventilation nasal mask has the following shortcomings:

[0004] 1. The mask body and headband of the existing positive pressure ventilation nasal mask are formed in one piece. When the positive pressure ventilation nasal mask needs to be removed, the headband must be removed first, and then the mask body must be taken off the face. The steps are cumbersome and the wearing or taking off time is long. Even in some emergency situations, when the mask needs to be worn in time, the best wearing time may be missed.

[0005] 2. In order to ensure that the existing positive pressure ventilation nasal mask does not leak, the headband of the existing positive pressure ventilation nasal mask is tightly tied to the user's head when worn, which causes the user to have a greater foreign body sensation on the head. The headband material is relatively hard and does not fit the user's face well. When the positive pressure ventilation nasal mask is taken off after use, an indentation will be formed on the user's face where the headband was originally worn, affecting the aesthetics of the user's face and providing a poor user experience.

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described features. In addition, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0049] The principle and structure of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0050] In one embodiment, referring to the attached Figure 1-7 The utility model provides a positive pressure ventilation nasal mask, including a nasal mask body 10 and a facial sealing portion 20 that matches the human face; the nasal mask body 10 is also connected to a ventilator to assist the user wearing the positive pressure ventilation nasal mask to maintain normal human breathing.

[0051] The side of the nose mask body 10 facing the facial sealing part 20 matches and fits the human face and is provided with a first magnetic body 11. The side of the facial sealing part 20 is correspondingly provided with a second magnetic body 21. The opposite surfaces of the second magnetic body 21 and the first magnetic body 11 can attract each other.

[0052] The interior of the nasal mask body 10 is a hollow structure.

[0053] When the user needs to use the positive pressure ventilation nasal mask, the facial sealing part 20 is first worn on the user's face, and then the nasal mask body 10 is magnetically connected to the second magnetic body 21 of the facial sealing part 20 through the first magnetic body 11. Such a connection can shorten the time of wearing or removing the nasal mask body 10 relative to the facial sealing part 20, thereby shortening the time of wearing or removing the positive pressure ventilation nasal mask, and the steps are simple. Even if the user needs to use a ventilator to assist breathing in time in some emergency situations, the positive pressure ventilation nasal mask of the utility model can be quickly worn, so that the user will not miss the best wearing time.

[0054] Because the side of the nasal mask body 10 facing the facial sealing portion 20 matches the human face and the facial sealing portion 20 matches the human face, the nasal mask body 10 can tightly fit the skin near the nose, preventing air leakage when the user wears the positive pressure ventilation nasal mask, which affects the use effect of the ventilator.

[0055] In one embodiment, referring to the attached Figure 1 Or 4, ear hooks 22 are respectively provided at both ends of the facial sealing portion 20.

[0056] Among them, the facial sealing part 20 is quickly worn on the user's face through the ear hanging part 22, and the structure of the facial sealing part 20 matches the human face, and the degree of fit with the human face is relatively high. Therefore, it can not only shorten the time for the user to wear the positive pressure ventilation nasal mask, but also prevent the user from having a strong foreign body sensation on the face, and the structure of the facial sealing part 20 is simple; and when the user uses the positive pressure ventilation nasal mask and takes it off, the user's face will not have indentations like wearing a headband, which will not affect the aesthetics of the user's face, thereby improving the user's experience.

[0057] Moreover, the facial sealing portion 20 is disposable. When the user uses the positive pressure ventilation nasal mask again, a new facial sealing portion 20 will be replaced, but the nasal mask body 10 still needs to be repeatedly cleaned and disinfected to reduce the risk of cross infection for the user.

[0058] Moreover, the material of the disposable facial sealing portion 20 is non-woven fabric, soft silicone, hydrogel or a composite material similar to a medical mask. Thus, compared with the headband of the existing positive pressure ventilation nasal mask made of a fabric composite or other special materials, the manufacturing cost of the facial sealing portion 20 of the utility model is lower.

[0059] In one embodiment, referring to the attached Figure 4 The side of the ear hook 22 facing away from the second magnetic body 21 is provided with an adhesive layer 24; the adhesive layer 24 can further fix the ear hook 22 at the rear edge of the user's ears. The adhesive layer 24 is preferably a medical adhesive tape, so that when the user takes off the positive pressure ventilation nasal mask after using it (i.e., when taking off the facial sealing part 20), the user's face will not have an indentation like wearing a headband, which will not affect the aesthetics of the user's face and improve the user's experience.

[0060] In this way, when the user puts the ear hooks 22 of the facial sealing part 20 on the user's ears, the isolation paper on the adhesive layer 24 is torn off first, so that the ear hooks 22 are bonded to the rear edges of the ears through the adhesive layer 24, so that the ear hooks 22 will not fall off the user's ears easily, and the facial appearance will not be affected after being torn off. When the adhesive layer 24 is bonded to the rear edges of the ears, the grease at the rear edges of the ears needs to be cleaned first to prevent bubbles from being generated during bonding, resulting in unstable bonding between the ear hooks 22 and the rear edges of the ears.

[0061] In one embodiment, referring to the attached Figure 2 , at least two of the first magnetic body 11 and the second magnetic body 21 are provided.

[0062] In this embodiment, two first magnetic bodies 11 and two second magnetic bodies 21 are used as examples. The side of the nose mask body 10 facing the facial seal part 20 is an annular structure, and a first magnetic body 11 is provided on both sides of the inner ring; correspondingly, two second magnetic bodies 21 are provided on one side of the facial seal part 20.

[0063] In this way, two first magnetic bodies 11 and two second magnetic bodies 21 can make the connection between the nasal mask body 10 and the facial sealing part 20 more stable, so that the nasal mask body 10 will not fall off relative to the facial sealing part 20 easily. However, three or more first magnetic bodies 11 and second magnetic bodies 21 will increase the cost, and one first magnetic body 11 and second magnetic body 21 will cause the connection between the nasal mask body 10 and the facial sealing part 20 to be unstable, so that the nasal mask body 10 will easily fall off relative to the facial sealing part 20.

[0064] Of course, in other embodiments (not shown in the figures), four first magnetic bodies 11 and four second magnetic bodies 21 are provided, and the four first magnetic bodies 11 are arranged in a "cross" shape around the inner ring of the nasal mask body 10 on one side facing the facial sealing portion 20.

[0065] The first magnetic body 11 is preferably made of a magnet, and the side of the first magnetic body 11 facing the second magnetic body 21 is the S pole; the second magnetic body 21 is preferably made of a magnet, and the side of the second magnetic body 21 facing the first magnetic body 11 is the N pole.

[0066] In other embodiments, the material of the first magnetic body 11 is preferably a magnet, and the side of the first magnetic body 11 facing the second magnetic body 21 is an N pole; the material of the second magnetic body 21 is preferably a magnet, but the side of the second magnetic body 21 facing the first magnetic body 11 is an S pole.

[0067] In other embodiments, the material of the first magnetic body 11 is preferably a magnet, and the material of the second magnetic body 21 is preferably a magnetic metal, and the magnetic metal is preferably iron.

[0068] In other embodiments, the material of the first magnetic body 11 is preferably a magnetic metal, and the magnetic metal is preferably iron, and the material of the second magnetic body 21 is preferably a magnet.

[0069] In one embodiment, referring to the attached Figure 2 The facial sealing part 20 is provided with a limiting piece 23 corresponding to each of the second magnetic bodies 21, and the bottom of each limiting piece 23 is provided with a second magnetic body 21; each of the first magnetic bodies 11 can be removed and inserted into the corresponding limiting piece 23 and attract each other with the second magnetic body 21 at the bottom.

[0070] Among them, the limiter 23 is a groove structure, so that when the first magnetic body 11 is matched and inserted into the limiter 23 and attracts the second magnetic body 21 at the bottom, the limiter 23 can prevent the connection between the first magnetic body 11 and the second magnetic body 21 from being offset, further enhancing the stability of the connection between the nose mask body 10 and the facial sealing part 20, and will not fall off easily.

[0071] In one embodiment, referring to the attached Figure 1 and attached Figure 3 The nasal mask body 10 includes a breathing duct 12, a shell 13, an annular connector 14 and an annular cushion 15; the shape of the side of the annular cushion 15 facing the facial sealing part 20 matches the human face.

[0072] One end of the breathing duct 12 is connected to one side of the shell 13, the other side of the shell 13 is connected to one side of the annular connector 14, the other side of the annular connector 14 is connected to one side of the annular gasket 15, and the other side of the annular gasket 15 is provided with a first magnetic body 11.

[0073] Among them, the side of the nasal mask body 10 facing the facial sealing part 20 is provided with a breathing duct 12, a shell 13, an annular connector 14 and an annular cushion 15 in sequence.

[0074] Among them, a circular through hole 133 is provided on the side of the shell 13 facing the breathing duct 12, and then one end of the breathing duct 12 is sleeved in the circular through hole 133, so that the breathing duct 12 is connected to the shell 13, and the nasal mask body 10 is a hollow structure, which is convenient for the ventilator to assist the user's nose breathing through the nasal mask body 10.

[0075] An exhaust hole 121 is provided on the top wall of the breathing duct 12, and the exhaust hole 121 is used to exhaust the carbon dioxide exhaled by the user.

[0076] In a specific embodiment, referring to the attached Figure 5 A first annular groove 131 is provided on the other side of the shell 13 facing the annular connector 14, and a plurality of grooves 132 are provided in the first annular groove 131; a first annular clamping member 141 is provided on the side of the annular connector 14 facing the shell 13, and a buckle 142 is provided in the first annular clamping member 141 corresponding to the groove 132.

[0077] When the first annular clamping member 141 is inserted into the first annular clamping groove 131 , the buckle 142 can be clamped with the clamping groove 132 .

[0078] In this way, the first annular clamping member 141 is inserted into the first annular clamping groove 131 and the buckle 142 is clamped with the clamping groove 132 , so that the connection between the housing 13 and the annular connecting member 14 is stable and will not fall off easily.

[0079] Preferably, three triangularly distributed grooves 132 are provided in the first annular groove 131 ; and correspondingly, three triangularly distributed buckles 142 are provided on the first annular clamping member 141 .

[0080] In a specific embodiment, referring to the attached Figure 6 The other side of the annular connector 14 facing the annular gasket 15 is provided with a second annular clamping member 143, and the side of the annular gasket 15 facing the annular connector 14 is correspondingly provided with a second annular clamping groove 151; the second annular clamping member 143 can be matched and inserted into the second annular clamping groove 151.

[0081] In this way, the second annular clamping member 143 is matched and inserted into the second annular clamping groove 151 and then bonded or secondary injection molded, so that the connection between the annular connector 14 and the annular gasket 15 is stable and will not fall off easily.

[0082] In one embodiment, the annular pad 15 is made of an elastic material, and the side of the annular pad 15 facing the facial sealing part 20 matches and fits the human face. In this way, when the user wears the positive pressure ventilation nasal mask, the elastic annular pad 15 can match and fit the skin near the user's nose to prevent air leakage from the facial sealing part 20. In this way, when the positive pressure ventilation nasal mask is used and the facial sealing part 20 is torn off, it is not easy to cause indentations on the user's face, which will not affect the aesthetics of the user's face and improve the user's experience.

[0083] In a specific embodiment, referring to the attached Figure 1 A through hole 25 is correspondingly provided in the middle of the facial sealing portion 20 , and the shape of the through hole 25 matches the inner ring shape of the annular gasket 15 .

[0084] In this way, when the user wears the facial sealing part 20, the user's nose will be exposed from the through hole 25, and then the nose mask body 10 will cover the user's face through the inner ring of the annular pad 15 to align with the user's nose, so that the respirator can assist the user's breathing.

[0085] In a specific embodiment, the connection between the annular gasket 15 and the first magnetic body 11 is preferably bonding or secondary injection molding, and the connection between the facial sealing portion 20 and the second magnetic body 21 is preferably bonding or secondary injection molding.

[0086] The method of using the positive pressure ventilation nasal mask of the utility model:

[0087] First, clean the grease at the rear edge of the ears, then tear off the isolation paper of the adhesive layer 24 of the facial sealing part 20, then put the ear hooks 22 behind the user's ears respectively, and then press the ear hooks 22 to make the adhesive layer 24 at the ear hooks 22 adhere to the rear edge of the ears.

[0088] Then, the first magnetic body 11 of the nasal mask body 10 is brought close to the second magnetic body 21 of the facial sealing part 20 so that the two attract each other, and then the nasal mask body 10 is turned upside down on the user's nose, and the annular pad 15 of the nasal mask body 10 will tightly adhere to the skin near the nose to prevent air leakage from occurring in the facial sealing part 20.

[0089] Then, after the breathing tube 12 is connected to the ventilator, the positive pressure ventilation nasal mask is checked for leakage. If there is leakage, the adhesive layer 24 needs to be torn off, rearranged and bonded to ensure that the positive pressure ventilation nasal mask does not leak when worn on the user's nose.
