Description

Technical Field

[0001] The present invention relates to the technical field of nebulizers, in particular to a nebulizer specially used for children. Background Art

[0002] Children's gastrointestinal function is not fully developed, and the gastrointestinal mucosa is relatively fragile. Oral medications can easily irritate children's gastrointestinal tract, causing increased gastric acid. Therefore, when treating children, the drug solution will be atomized through a nebulizer so that the drug can reach the lesion directly and eliminate local inflammatory infection.

[0003] The nebulizer is mainly composed of a main unit and a mask. During use, the mask is attached to the child's face, the main unit is started, the medicine liquid is atomized, the atomized medicine liquid enters the mask, and the child inhales the atomized medicine liquid for treatment. During the treatment, the child may feel unfamiliar and uneasy about the nebulizer, and the mask may cause the child's breathing to be restricted, causing the child to resist. The child may push the mask away, while the main unit is working, and the medicine mist is discharged from the mist outlet of the mask, resulting in a waste of medicine liquid. Summary of the invention

[0031] like Figure 6-Figure 8 As shown, the fixing mechanism 13 includes a headband 131, an arc-shaped shell 132, a winding shaft 133 and a fixing assembly. The headband 131 is connected to the front and rear sides of the mask 5. The two headbands 131 slide through the front and rear sides of the arc-shaped shell 132 respectively. Two winding shafts 133 are rotatably connected to the middle part of the arc-shaped shell 132. The headband 131 is wound around the winding shaft 133. The two winding shafts 133 are driven by transmission gears. The fixing assembly is used to fix the headband 131.

[0032] like Figure 6-Figure 8 As shown, the fixing assembly includes a slider 134, an elastic member 135 and a card pin 136. The slider 134 is slidably connected to the front and rear sides of the right side of the arc shell 132. Two elastic members 135 are connected between the slider 134 and the arc shell 132. The elastic member 135 is located in the arc shell 132. The elastic member 135 is a spring. A plurality of card pins 136 are evenly spacedly connected to the left side of the slider 134. The card pin 136 passes through the headband 131.

[0033] The medical staff puts the mask 5 on the child's face, and puts the headband 131 and the arc-shaped shell 132 on the child's head. The airbag 12 shrinks after being compressed, and the air in the airbag 12 enters the piston cavity through the trachea 11. The air pushes the piston block 7 to move upward, and the piston block 7 drives the connecting rod 10 to move upward, and the connecting rod 10 drives the sliding ring 9 to move upward, and the sliding ring 9 drives the fixed block 125 to move upward, and the fixed block 125 moves upward and drives the rack 124 to move forward through the guide groove 126, and the rack 124 drives the opposite gear 124 at the rear side. 23 rotates, and the two connecting shafts 121 rotate in opposite directions through the opposing gears 123. The connecting shaft 121 drives the baffle 122 to rotate, so that the baffle 122 no longer blocks the right end of the hard tube 4, and then pulls the slider 134 to the right, the elastic member 135 is compressed, and the slider 134 drives the card pin 136 to move to the right, loosening the headband 131, and then rotating one of the winding shafts 133. The two winding shafts 133 can rotate at the same time through the transmission gear, and the winding shaft 133 rewinds the headband 131, and the headband 131 is slowly tightened to fix the mask 5 on the child's face. Finally, the slider 134 is released. Under the action of the second elastic member 135, the slider 134 moves to the left, and the slider 134 drives the card pin 136 to move to the left. The card pin 136 is inserted into the headband 131 to fix the headband 131, and the atomizer body 1 is started. The atomizer body 1 atomizes the liquid medicine, and the atomized liquid medicine enters the box 3 through the hose 2, and then the atomized liquid medicine enters the mask 5 through the hard tube 4. The child inhales the atomized liquid medicine, thereby achieving the effect of curing the disease. If the child resists and takes off the mask 5, the airbag 12 will be out of contact with the child's face. , the airbag 12 is no longer under pressure, and under the action of the elastic member 8, the piston block 7 moves downward, the piston block 7 drives the connecting rod 10 to move downward, the connecting rod 10 drives the sliding ring 9 to move downward, the sliding ring 9 drives the fixed block 125 to move downward, the fixed block 125 moves downward and drives the rack 124 to move backward through the guide groove 126, the rack 124 drives the opposite gear 123 on the rear side to rotate in the opposite direction, so that the baffle 122 can rotate in the opposite direction, and the baffle 122 blocks the right end of the hard tube 4 again, and the atomized liquid medicine cannot enter the mask 5, avoiding waste.

[0034] Second implementation method: Based on the first implementation method, Fig. 9 and Fig.12 As shown, it also includes a rotating shaft 14 and a clamping block 15. The lower part of the box body 3 is rotatably connected to the rotating shaft 14. There is damping between the rotating shaft 14 and the box body 3. The front and rear ends of the rotating shaft 14 are connected to the clamping blocks 15. The front and rear sides of the sliding ring 9 are both provided with clamping grooves 16, and the top of the clamping groove 16 is provided with an arc groove 20.

[0035] There is damping between the rotating shaft 14 and the box body 3, so the rotating shaft 14 and the block 15 will not rotate downward easily, preventing the block 15 from affecting the up and down movement of the sliding ring 9. When the box body 3 and the inside of the hard tube 4 need to be cleaned, the medical staff will remove the mask 5, then push the sliding ring 9 upward, open the baffle 122, and then rotate the block 15 into the slot 16 to lock the sliding ring 9, so that the baffle 122 remains in the open state, which is convenient for medical staff to clean the inside of the box body 3 and the hard tube 4. At the same time, the block 15 will enter the arc groove 20, and the arc groove 20 can limit the block 15 to prevent the block 15 from moving out of the slot 16.

[0036] like Fig.10 and Fig.11 As shown, a reflux pipe 17 is also included. The lower part of the box body 3 and the lower part of the hard tube 4 are connected together by the reflux pipe 17. The lower end of the reflux pipe 17 is connected to the left side of the atomizer body 1. A reflux groove 18 is opened on the right side of the bottom of the hard tube 4. The reflux groove 18 is connected to the reflux pipe 17.

[0037] like Fig.11 As shown, a stopper 19 is also included, and the stopper 19 is connected to the left side of the bottom of the hard tube 4.

[0038] When treatment is not needed, the nebulizer body 1 is closed, and the baffle 122 is also closed. The atomized medicine liquid will remain in the hard tube 4 to form water droplets. The water droplets flow downward, and the block 19 blocks the medicine liquid to prevent the medicine liquid from flowing into the box body 3. The medicine liquid will flow into the reflux groove 18, and the medicine liquid will flow back to the nebulizer body 1 through the reflux pipe 17. In this way, the medicine liquid remaining in the hard tube 4 can be recovered, thereby saving resources.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
