Description

Technical Field

[0001] The invention relates to the technical field of breathing masks, in particular to a novel atomizing mask. Background Art

[0002] For the traditional method of taking medicine to treat respiratory diseases such as asthma, the medical nebulizer atomizes the liquid medicine into tiny particles, and the medicine enters the respiratory tract and lungs through inhalation, thereby achieving the purpose of painless, rapid and effective treatment. It can treat respiratory infections, eliminate inflammation and edema, relieve spasms, thin sputum, and help expectoration.

[0003] Existing atomization masks for atomization therapy generally include a mask body, a fixing belt arranged on the mask body, and an air inlet hole arranged on the mask body. The air inlet hole is connected to an air inlet pipe. Patients often inhale medicine through the mouth and exhale through the nostrils. The medicine can effectively enter the respiratory tract, so that the atomized medicine liquid can reach deep into the lungs to achieve a therapeutic effect. However, people are accustomed to breathing through their nostrils in daily life, and part of the medicine liquid is inhaled through the nostrils, resulting in insufficient medication and waste of medicine liquid. Summary of the invention

[0004] In order to solve the problem that the existing atomizer mask covers the mouth and nose together, which makes it easy for part of the medicine liquid to be inhaled by the nostrils, resulting in insufficient medication, the present invention provides a new type of atomizer mask, which separates the oral area and the nasal area by arranging a partition inside the mask body, effectively assisting the patient to perform oral inhalation and nasal breathing, thereby improving the atomization treatment effect.

[0005] The present invention provides a novel atomizing mask, comprising a mask body connected to an atomizer, a cavity being arranged in the mask body, a partition being arranged inside the mask body, the partition dividing the cavity into an upper nasal area and a lower oral area, the nasal area and the oral area being two independent areas, an air outlet being arranged in the upper part of the mask body, the nasal area being connected to the external air through the air outlet, an air inlet being arranged in the lower part of the mask body, the oral area being connected to the atomizer through the air inlet. The cavity inside the mask body is divided into a nasal area and an oral area by the partition, and an air inlet pipe is connected to the oral area, the nasal area and the oral area are not connected to each other, so as to assist the patient in performing oral inhalation and nasal exhalation operations, and improve the utilization rate of liquid medicine.

[0006] Furthermore, two air outlets are provided on the upper part of the mask body, and the two air outlets are symmetrically arranged on both sides of the mask body, and a one-way valve is installed in the air outlet holes. The two air outlets are arranged corresponding to the nostrils on both sides, and the one-way valve can ensure that the nasal cavity can only exhale but not inhale.

[0007] Furthermore, the partition is an arc-shaped plate, and the arc surface of the arc-shaped plate is bent toward the nasal cavity area. The arc-shaped partition can better fit the philtrum position between the oral cavity and the nasal cavity, thereby ensuring that the nasal cavity area and the oral cavity area are not connected.

[0008] Furthermore, one side of the partition is fixedly connected to the inner wall of the cover body, and the other side is provided with a sealing strip. By providing the sealing strip at the part of the partition contacting the philtrum, it is further ensured that the nasal cavity area and the oral cavity area are not connected.

[0009] Furthermore, the sealing strip includes a limiting portion and a sealing portion. The limiting portion is formed on the end surface of the partition and is composed of an upper sealing strip and a lower sealing strip. The sealing portion is a thin sheet arranged between the upper sealing strip and the lower sealing strip. The upper sealing strip and the lower sealing strip are used to seal and position the partition, and the thin sheet is used to hold the gas exhaled from the nasal cavity to prevent the gas from leaking downward to the oral area.

[0010] Furthermore, the width of the thin sheet is greater than the width of the upper seal and the lower seal, and the thin sheet extends from between the upper seal and the lower seal. The thin sheet is first positioned by the upper seal and the lower seal, and then sealed by the thin sheet.

[0011] Furthermore, the upper seal is inclined toward the nasal area, the lower seal is inclined toward the oral area, and the thin sheet extending from the upper seal and the lower seal is inclined toward the nasal area. The upper seal and the lower seal are in a V-shape that opens outward, and the positioning effect is good. The thin sheet inclined toward the nasal area can better hold the gas exhaled from the nasal cavity.

[0012] Furthermore, the upper seal strip, the lower seal strip and the thin sheet are all arc-shaped. The arc-shaped surface can better fit closely with the face and improve the sealing performance.

[0013] Furthermore, a sealing ring in contact with the face is arranged around the mask body, and the sealing ring includes a limiting ring and a sealing ring sheet, the limiting ring is formed around the mask body, and is composed of an inner ring and an outer ring, and the sealing ring sheet is arranged between the inner ring and the outer ring. The sealing ring improves the overall sealing effect of the mask body.

[0014] Furthermore, the inner ring, the outer ring and the sealing ring are all arc-shaped, the inner ring is bent toward the inside of the cover, the outer ring is bent toward the outside of the cover, and the sealing ring is bent toward the inside of the cover. Positioning is performed by the inner ring and the outer ring, and the sealing ring bent toward the inside of the cover prevents gas leakage.

[0015] The beneficial effects of the present invention are: The present invention provides a novel atomizing mask, which divides the inner cavity of the mask body into a nasal area for exhalation only and an oral area for inhalation only by arranging a partition, and connects an air inlet pipe with the oral area, while the nasal area and the oral area are not connected with each other, so as to assist the patient in performing oral inhalation and nasal exhalation operations, so as to improve the utilization rate of liquid medicine; with the sealing strip arranged at the end of the partition and the sealing ring arranged around the mask body, not only can the mask body be effectively fixed on the face, but also the gas can be trapped by the thin sheet to prevent the gas from leaking out, and the thin sheet structure is not easy to cause pressure sores on the face, so as to effectively improve the atomizing efficiency.

DETAILED DESCRIPTION

[0017] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] In order to assist patients in oral inhalation and nasal exhalation, a new type of atomizer mask is designed. Figure 1 As shown, it includes a mask body 2 connected to the atomizer 1, a cavity is provided in the mask body 2, a partition 3 is provided inside the mask body 2, the partition 3 divides the cavity into an upper nasal area 4 and a lower oral area 5, the nasal area 4 and the oral area 5 are two independent areas, an air outlet 6 is opened at the upper part of the mask body 2, the nasal area 4 is communicated with the external air through the air outlet 6, an air inlet 7 is opened at the lower part of the mask body 2, and the oral area 5 is communicated with the atomizer 1 through the air inlet 7. The gas delivery end of the nebulizer 1 is detachably connected to a mask body 2, and a partition 3 is arranged inside the mask body 2 to divide the mask body cavity into two chambers. The upper side of the partition 3 is a nasal area 4, and the lower side of the partition 3 is an oral area 5. The nasal area 4 is provided with two air outlets 6 connected to the outside air, which is convenient for the patient to exhale gas. The oral area 5 is provided with an air inlet 7 connected to the nebulizer 1. The air inlet 7 inputs the liquid medicine atomized into tiny particles by the nebulizer 1 into the oral area 5, which is convenient for the patient to inhale the liquid medicine with the mouth, and the medicine can effectively enter the respiratory tract and then reach deep into the lungs to play a therapeutic role.

[0019] In order to assist the patient to exhale through the nasal cavity, two air outlet holes 6 are provided on the upper part of the mask body 2, and the two air outlet holes 6 are symmetrically arranged on both sides of the mask body 2, and a one-way valve 61 is installed in the air outlet hole 6. The one-way valve 61 is arranged so that the nasal area 4 can only exhale gas, but not inhale gas, and cooperate with the inhalation of the liquid medicine in the oral area 5, which can better assist the patient in treatment.

[0020] like Figure 2 As shown, the partition 3 is an arc-shaped plate, and the arc surface of the arc-shaped plate is bent toward the nasal cavity area 4. The arrangement of the arc-shaped plate can more effectively fit the philtrum area between the nasal cavity and the oral cavity, so that the airflows of the nasal cavity area 4 and the oral cavity area 5 will not conflict with each other, thereby improving the utilization rate of the atomized liquid medicine and reducing waste.

[0021] In order to further improve the sealing performance, one side of the partition 3 is fixedly connected to the inner wall of the mask body 2, and the other side is provided with a sealing strip 9. The sealing strip 9 is against the philtrum to improve the sealing performance of the nasal area 4 and the oral area 5, so that the airflow between the two areas will not be connected.

[0022] like Figure 3 As shown, the core of the technical solution is that the sealing strip 9 includes a limiting portion and a sealing portion. The limiting portion is formed on the end surface of the partition 3 and is composed of an upper sealing strip 91 and a lower sealing strip 92. The sealing portion is a thin sheet 93 arranged between the upper sealing strip 91 and the lower sealing strip 92. The width of the thin sheet 93 is greater than the width of the upper sealing strip 91 and the lower sealing strip 92, and the thin sheet 93 extends from between the upper sealing strip 91 and the lower sealing strip 92. The upper sealing strip 91 and the lower sealing strip 92 are used for primary sealing, and the thin sheet 93 is used for secondary sealing. Among them, the upper sealing strip 91 is inclined toward the nasal cavity area 4, the lower sealing strip 92 is inclined toward the oral cavity area 5, and the thin sheet 93 extending from the upper sealing strip 91 and the lower sealing strip 92 is inclined toward the nasal cavity area 4. Preferably, the upper sealing strip 91, the lower sealing strip 92 and the thin sheet 93 are all arc-shaped.

[0023] The partition 3 is generally made of PVC or PP, and the upper seal 91 and the lower seal 92 are integrally formed with the partition 3, and then the thin sheet 93 is bonded between the upper seal 91 and the lower seal 92 for sealing. The thin sheet 93 is generally made of nitrile rubber. When the mask body 2 is worn on the patient's face, the thin sheet 93 first touches the philtrum and bends along the bending direction inclined toward the nasal cavity area 4 until the upper seal 91 and the lower seal 92 touch the philtrum. At this time, the upper seal 91 and the lower seal 92 press against the philtrum to limit and seal, and the bent thin sheet 93 fits tightly with the philtrum, further improving the sealing performance and preventing the airflow in the upper and lower areas of the partition 3 from communicating. When there is gas exhaled in the nasal cavity area 4, the bent thin sheet 93 will hold it, and the exhaled gas will apply a thrust toward the oral cavity area 5 to the thin sheet 93. Under the action of this thrust, the contact area between the end of the bent thin sheet 93 and the philtrum will become larger, which will make the contact tighter. Therefore, the sealing performance can be guaranteed.

[0024] like Figure 3As shown, in order to improve the overall sealing performance of the mask body 2, a sealing ring 8 in contact with the face is arranged around the mask body 2, and the sealing ring 8 includes a limiting ring and a sealing ring piece 83. The limiting ring is formed around the mask body 2 and is composed of an inner ring 81 and an outer ring 82, and the sealing ring piece 83 is arranged between the inner ring 81 and the outer ring 82. Preferably, the inner ring 81, the outer ring 82 and the sealing ring piece 83 are all arc-shaped, the inner ring 81 is bent toward the inside of the mask body 2, the outer ring 82 is bent toward the outside of the mask body 2, and the sealing ring piece 83 is bent toward the inside of the mask body 2.

[0025] The mask body 2 is generally made of PVC or PP, the inner ring 81 and the outer ring 82 are integrally formed with the mask body 2, and then the sealing ring piece 83 is bonded between the inner ring 81 and the outer ring 82 for sealing, and the sealing ring piece 83 is made of nitrile rubber. When the mask body 2 is worn on the patient's face, the sealing ring piece 83 first contacts the face and bends along the bending direction inclined toward the inside of the mask body 2 until the inner ring 81 and the outer ring 82 contact the face. At this time, the inner ring 81 and the outer ring 82 contact the face for limiting and sealing, and the curved sealing ring piece 83 fits tightly with the face, further improving the sealing performance, preventing the internal gas of the mask body 1 from communicating with the external gas. When there is gas exhaled from the inside of the mask body 2, the curved sealing ring piece 83 will hold it, and the exhaled gas will apply a thrust toward the outside of the mask body 2 to the sealing ring piece 83. Under the action of this thrust, the end of the curved sealing ring piece 83 will increase the contact area with the face, which will make the contact tighter, so the sealing performance can be guaranteed.

[0026] The above description is only illustrative rather than restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the appended claims, but all will fall within the scope of protection of the present invention.
