Description

Nebulizer mask to prevent drug leakage

Technical Field

The utility model relates to an atomizing mask, in particular to an atomizing mask which can prevent medicine from leaking out.

Background Art

Nebulizer therapy refers to using a nebulizer to disperse drugs into tiny droplets or particles, suspend them in the gas, and inhale them into the respiratory tract and lungs to clean the airway, humidify the airway, and achieve local and systemic treatment. Existing drug nebulizers include a nebulizer for forming aerosols, and the nebulizer is formed with an aerosol outlet, and the aerosol outlet is detachably connected to a nebulizer mask. The patient wears the nebulizer mask on the mouth and nose and inhales the droplets or particles for treatment.

Atomizer masks are divided into oral type and mask type. The oral atomizer mask is provided with an oral mouthpiece connected to the aerosol outlet, and the drug particles enter the patient's mouth directly from the aerosol outlet through the oral mouthpiece. The oral atomizer mask can effectively avoid drug leakage and waste, but because the oral mouthpiece directly enters the oral cavity, as the treatment time continues, the patient's foreign body sensation and rejection will become more and more intense, and for patients with poor self-care ability, it is also very inconvenient to let them rely on self-oral control to cooperate with the treatment. The mask atomizer mask is provided with a conical cup connected to the aerosol outlet. In order to make the patient breathe more smoothly when using it, a vent is provided on the cup. When using it, the cup is directly covered on the mouth and nose, and the drug particles enter from the aerosol outlet and fill the cup. The patient can inhale the drug particles with normal breathing, which is convenient to operate and will not produce a foreign body sensation and rejection. For example, the invention patent application with publication number CN104606760A discloses an atomizer mask, including a cup, and the cup is provided with a vent.

Although the above-mentioned mask-type atomizing mask does not produce a foreign body sensation or a sense of rejection, as the patient breathes normally, drug particles will also leak out from the air holes when exhaling, resulting in a waste of drug.

Example 1 Atomizing mask to prevent drug leakage

As shown in FIG. 1 and FIG. 2 , this embodiment is an atomizing mask for preventing drug leakage, comprising a cup 1, one side of the cup 1 is connected to a connecting portion 2 for being fixedly connected to the aerosol outlet of the atomizing device, the other side of the cup 1 is an opening for fitting over the mouth and nose, a guide channel 3 connected to the aerosol outlet of the atomizing device is arranged inside the cup 1, and an air vent 4 is arranged on the cup 1.

Currently, common mask-type atomizing masks are divided into two types: horizontal type and vertical type. The horizontal type atomizing mask is suitable for atomizers with aerosol outlets arranged horizontally, and the vertical type atomizing mask is suitable for atomizers with aerosol outlets arranged vertically. This embodiment is described by taking the horizontal type atomizing mask as an example. The cup 1 of the horizontal type atomizing mask is a horizontally placed conical structure, and the side with a larger size of the conical structure is an opening for fitting on the face. The outer edge of the side with a larger size of the conical structure is provided with a mounting hole 5, and an elastic rope can be provided on the mounting hole 5 to fix the cup 1 on the user's face.

The smaller side of the conical structure is connected to a connecting portion 2 for being fixedly connected to the aerosol outlet of the atomizer. The connecting portion 2 is connected to the center position of the cone of the cup 1. The connecting portion 2 is a tubular structure extending toward the inner side of the cup 1 and connected to the side wall of the cup 1. The tubular structure is used to be sleeved on the aerosol outlet of the atomizer. The inner diameter of the tubular structure is adapted to the outer diameter of the aerosol outlet of the atomizer. Since the axial direction of the connecting portion 2 is arranged horizontally, this embodiment is called a horizontal atomizing mask.

The guide channel 3 is integrally connected to the end of the tubular structure of the connecting part 2. The guide channel 3 is trumpet-shaped. The size of the guide channel 3 on the side close to the connecting part 2 is adapted to the connecting part 2, and the size of the guide channel 3 on the side away from the connecting part 2 is larger than the size of the guide channel 3 on the side close to the connecting part 2. Since the connecting part 2 is arranged in the middle of the cup 1, the opening of the guide channel 3 is also toward the middle of the cup 1. This position allows the opening of the guide channel 3 to face the patient's mouth and nose after the patient wears it. The end of the guide channel 3 on the side away from the connecting part 2 is shorter than the outer edge of the cup 1, so that the end of the guide channel 3 is closely connected to the wearer's face. There is a distance, the ventilation hole 4 is arranged on the back side of the guide channel 3 on the cup 1, where the back side refers to the outside of the guide channel 3, that is, the ventilation hole 4 is arranged on the cup 1 at a position corresponding to the outside of the guide channel 3. Specifically, the ventilation hole 4 of this embodiment is arranged on one side of the cup 1 close to the connecting portion 2, and one is arranged on each side of the connecting portion 2 in the horizontal direction, which can effectively prevent the drug particles in the guide channel 3 from leaking out of the ventilation hole 4. Of course, the number and position of the ventilation holes 4 can also be adjusted according to actual needs, and it is only necessary to ensure that the ventilation holes 4 are arranged on the back side of the guide channel 3 on the cup 1.

Since the connecting part 2 needs to be sleeved on the aerosol outlet of the atomizing device, in order to ensure that the connecting part 2 is accurately sleeved, a limiting shoulder 6 is fixedly provided on the inner wall between the guide channel 3 and the connecting part 2. The limiting shoulder 6 is an annular protrusion formed on the inner wall between the guide channel 3 and the connecting part 2, which plays a limiting role to prevent the aerosol outlet of the atomizing device from being sleeved into the guide channel 3.

When in use, the connecting portion 2 of this embodiment is sleeved on the aerosol outlet of the atomizing device, and the atomizing device is turned on. The drug particles enter the cup 1 from the guide channel 3. The guide channel 3 allows the drug particles to directly reach the user's face. When the user inhales, the drug particles can be almost completely inhaled into the mouth and nose. When the user exhales, the location of the air vent 4 can avoid the drug particles from leaking out directly without being inhaled to the greatest extent, thereby preventing the leakage and waste of drug particles.

Example 2 Atomizing mask to prevent drug leakage

This embodiment is a spray mask for preventing medicine from leaking out, as shown in Figures 3 and 4. The spray mask in this embodiment is a vertical spray mask, which is suitable for a sprayer with a vertically arranged aerosol outlet.

The cup 1 of the atomizing mask in this embodiment is an elliptical open shape with a protruding portion. The elliptical shape refers to an elliptical shape whose main viewing direction of the outer edge of the cup 1 is along the vertical direction. The open shape refers to one side of the side view of the cup 1 being an opening for fitting on the face, and the other side of the cup 1 being a protruding portion. The lower edge of the protruding portion is connected to a connecting portion 2 with a tubular structure that is opened downward. The guide channel 3 is integrally connected to the end of the tubular structure of the connecting portion 2 located at one end inside the cup 1, and the opening of the guide channel 3 faces the upper part of the cup 1. Further, since the connecting portion 2 of the vertical atomizing mask itself is relatively close to the side wall of the cup 1, the guide channel 3 in this embodiment is a convex arc structure formed on the wall of the cup 1, so that part of the side wall of the cup 1 forms the side wall of the guide channel 3, and the guide channel 3 is adapted to the connecting portion 2 on the side close to the connecting portion 2, and the size of the guide channel 3 away from the connecting portion 2 is larger than the size of the guide channel 3 on the side close to the connecting portion 2, so that the guide channel 3 forms an open structure arranged toward the opening side of the cup 1. Since the opening of the guide channel 3 is toward the upper part of the cup 1, there are two air holes 4 in this embodiment, both of which are arranged in the middle of the cup 1 (for a clearer illustration, the position of the air holes 4 is shown in FIG. 4 ). The middle position is farther away from the flow direction of the drug particles. The arrangement position of the air holes 4 can effectively prevent the drug particles in the guide channel 3 from leaking out. Of course, the number and arrangement position of the air holes 4 can also be adjusted according to actual needs, and it is only necessary to ensure that the air holes 4 are arranged on the back side of the guide channel 3 on the cup 1.

For the method of using this embodiment, please refer to Example 1.
