Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an oral and nasal mask type atomizer. Background Art

[0002] Nebulizer therapy mainly refers to aerosol inhalation therapy. The so-called aerosol refers to tiny solid or liquid particles suspended in the air. Therefore, nebulizer inhalation therapy uses a nebulizer to disperse the drug into tiny droplets or particles, suspending them in the gas and entering the respiratory tract and lungs to achieve the therapeutic purposes of moistening the airway, relieving cough and phlegm, relieving spasms and asthma, and inhaling anesthetic drugs before surgery.

[0003] There are two main forms of atomization: oxygen atomization and ultrasonic atomization inhalation. Compared with taking medicine or injections, atomization therapy has certain advantages. First, atomization can deliver drugs directly to the patient's respiratory tract and lungs, and it takes effect faster than oral drugs. Secondly, since the drug acts directly on the target cells and does not need to circulate through the blood, the systemic absorption is small, the dosage is small, the side effects are reduced, and the systemic adverse reactions are small. In addition, since atomization therapy does not require the patient to deliberately cooperate, it is suitable for children and critically ill patients.

[0004] However, the existing nebulizers have the following problems: first, the patient needs to hold the nebulizer in hand during nebulization, and holding it for a long time will cause fatigue in the patient's hands; second, when the patient needs nasal nebulization, a nasal tube nebulizer is needed, and when the patient needs oral nebulization, an oral tube nebulizer is needed. On the one hand, there is a problem of inconvenience in use, and on the other hand, since nasal and oral nebulization cannot be performed at the same time, there are problems of low nebulization efficiency and long nebulization time.

Among them, the mist outlet device 42 can adopt an existing compressed air mist outlet structure or an ultrasonic mist outlet structure. Its specific structure and principle are well known to those skilled in the art, so they are not described here.

[0029] See also Figure 4 and Figure 5 In this embodiment, the liquid medicine container 41 includes an upper sphere 412 and a lower sphere 413. The lower part of the upper sphere 412 and the upper part of the lower sphere 413 are detachably connected and surround a medicine storage space 411.

When separate nasal atomization is required, the control valve 34 can be used to control the first connector 31 to be connected to the third connector 33 and the second connector 32 to be disconnected from the third connector 33. Then, the drug atomized by the atomization assembly 4 can enter the nasal space 12 through the third connector 33, the first connector 31 and the nasal passage connector 14 to achieve nasal atomization treatment. At the same time, it will not affect the oral cavity in the oral space 13. When separate oral atomization is required, the drug atomized by the atomization assembly 4 can be used to enter the nasal space 12 through the third connector 33, the first connector 31 and the nasal passage connector 14. The control valve 34 controls the second connector 32 to be connected to the third connector 33 while the first connector 31 is disconnected from the third connector 33. The drug atomized by the atomizing assembly 4 can enter the oral cavity space 13 through the third connector 33, the second connector 32 and the oral cavity passage connector 15 to achieve oral atomization treatment without affecting the nasal cavity in the nasal cavity space 12. When the nasal cavity and the oral cavity need to be atomized at the same time, the control valve 34 controls both the first connector 31 and the second connector 32 to be connected to the third connector 33, so that the drug atomized by the atomizing assembly 4 can enter the oral cavity space 13 through the third connector 33, the second connector 32 and the oral cavity passage connector 15. Through the third connector 33, they enter the first connector 31 and the second connector 32 respectively, and then enter the nasal space 12 and the oral space 13 respectively, so as to realize nasal atomization treatment and oral atomization treatment at the same time.

It has strong compatibility, so that patients can choose according to their actual situation, without having to switch between nasal tube-type nebulizers and oral tube-type nebulizers, which can improve the efficiency of atomization treatment and make it more convenient and comfortable to use. Furthermore, the oral-nasal mask-type nebulizer 100 of the utility model is provided with a strap 2 on the mask body 1, and the oral-nasal mask-type nebulizer 100 can be fixed to the patient's head by the strap 2. There is no need to hold the nebulizer during atomization, which frees the patient's hands. In addition, due to the double-capsule structure at the bottom of the medicine liquid container 41 and the weight of the mist outlet device 42 itself, under the action of gravity, the lower part of the medicine liquid container 41 naturally sags, so that the medicine is gathered at the air flow hole 413f (the lowest point), avoiding the inefficient or ineffective mist outlet caused by the medicine being higher than the air flow hole 413f. The double-capsule structure can help in the atomization process. The gap 413d between the outer capsule 413a and the inner capsule 413b can collect and store the condensed water generated in the medicine storage space 411, while reducing the cooling stimulation brought by the medicine liquid container 41 during atomization, and it is also very convenient to clean.
