Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a medical atomization device. 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 an atomizing device to disperse the drug into tiny droplets or particles, suspending them in the gas and entering the respiratory tract and lungs to achieve the purpose of cleaning the airway, humidifying the airway, local treatment and systemic treatment. Nebulizer inhalation therapy is one of the main means of respiratory treatment for preschool children. Commonly used nebulized drugs include inhaled corticosteroids, adrenergic receptor agonists, muscarinic receptor blockers, expectorants, hypertonic saline, etc. While the sick child is breathing oxygen, the expectorant is atomized through the high-frequency vibration of the atomizing end of the nebulizer and inhaled into the body through the respiratory tract. However, when performing the nebulization operation, young infants are often in a lying position. Therefore, when nebulizing them, medical staff or parents are often required to hold the nebulizer device to keep the mask in contact with the child's face for nebulization. On the one hand, manual holding for a long time is tiring. On the other hand, fatigue from manual holding may cause the mask to not fit the patient's face, resulting in poor nebulization effect. Therefore, it is necessary to provide a nebulizer device that can nebulize child patients in different postures. Summary of the invention

[0003] The present invention is intended to provide a medical atomization device, so as to provide an atomization device capable of atomizing pediatric patients in different postures.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a medical atomization device, comprising a bracket unit and an atomization unit, the atomization unit comprising an atomization barrel, a medicine capsule and a mask portion connected to the atomization barrel, the bracket unit is also provided with a rotating portion capable of adjusting the angle of the atomization barrel, the atomization barrel and the rotating portion are detachably connected, a connecting portion is provided on one side of the atomization barrel, the connecting portion comprises a rotary block, a connecting pipe and an ear plate fixedly connected to the atomization barrel, the rotary block is rotatably mounted on the ear plate and can be rotated at least 180 degrees, an installation groove for installing the medicine capsule is opened on the rotary block, and the connecting pipe connects the installation groove with the atomization barrel.

[0005] The beneficial effects of this program are:

[0006] In the technical solution, the rotating part is arranged as mentioned above to drive the nebulizer tube to rotate a certain angle, so that the nebulizer tube can be bent down a certain angle, driving the mask part to be close to the face of the lying child. After adjusting to the set position, the medicine bag is installed on the rotary block after the rotary block is rotated, so that the medicine bag is in a vertical state during operation, and the medicine liquid can completely enter the nebulizer tube to ensure full utilization of the medicine; on the other hand, the nebulizer unit is arranged on the bracket unit, and the bracket unit provides reliable support for the nebulizer equipment, avoids fatigue problems caused by hand-held operation, ensures that it can work stably, and ensures that the mask and the face are closely fitted during treatment by adjusting the angle between the mask and the patient's face. At the same time, the adjustment function of the rotating part enables the device to adapt to different patient postures, such as lying, semi-lying, and sitting, to ensure that the device is stable during operation and will not affect the treatment effect due to patient movement or posture changes.

[0007] Preferably, as an improvement, there are two ear plates and they are distributed on both sides of the rotary block, annular grooves are provided on the sides of the ear plates relative to the rotary block, retention parts are provided on both sides of the rotary block, the retention parts include a plurality of spring grooves evenly distributed circumferentially on the rotary block, a spring is provided in each spring groove, one end of the spring is fixed to the bottom surface of the spring groove, and the other end is against the annular groove.

[0008] The beneficial effects are as follows: by arranging a spring to resist the annular groove, the friction force of the rotary block relative to the ear plate can be increased. When the rotary block is manually moved to a suitable position during use, the elastic force generated by the spring can increase the friction force of the rotary block relative to the ear plate when it rotates; the damping effect of the rotary block during rotation is enhanced, so that the rotary block will not loosen or rotate accidentally due to slight vibration or external interference. By manually moving the rotary block, the elastic resistance of the spring can be overcome to achieve precise adjustment of the angle; the rotary block can carry the medicine capsule and stay at this angle without continuing to swing; the vertical state of the medicine capsule can be adjusted to the position at any time according to actual needs, ensuring the best effect of the medicine liquid flowing into the atomizer tube, and avoiding leakage of medicine liquid or interruption of atomization due to loosening of the rotary block.

[0009] Preferably, as an improvement, the bracket unit includes a base part and a sliding rod, the base part includes two U-shaped frames, both ends of the sliding rod are slidably connected to the two U-shaped frames respectively, a sliding seat is slidably provided on the sliding rod, a chassis is provided on the sliding seat, and the rotating part is rotatably arranged on the chassis.

[0010] The beneficial effects are as follows: when in use, the U-shaped frame is placed on both sides of the lying baby's body, and the slide bar slides along the U-shaped frame to a suitable position, providing a stable foundation for the nebulizer tube to support it. It can be placed on both sides of the baby's body without hindering the baby's activities. The angle of the rotating part is adjusted, and then the angle of the nebulizer tube is adjusted by the rotating part, so that the mask part fits the face of the child more closely. Even if the child swings his head in sleep, since the rotating part is rotatably arranged on the chassis, the nebulizer tube can rotate a certain amplitude with the swing of the baby's head, so that the mask part is always in contact with the child's face, avoiding the mask detachment caused by the movement of the head, thereby ensuring the effectiveness and continuity of the nebulizer inhalation. The above-mentioned setting provides a flexible adjustment space, which can adapt to babies in different postures, and at the same time ensures that the mask can be accurately aligned with the baby's face, avoiding the effect of the nebulizer treatment affected by the position offset, and the adjustment of the nebulizer tube can be completed quickly, saving preparation time and improving the treatment efficiency.

[0011] Preferably, as an improvement, the rotating part includes a rotating disk, a mounting support, a gear part and a rotating seat arranged on the rotating disk, the upper part of the mounting support is detachably sleeved with the mounting seat, the atomizer can be placed on the mounting seat, the gear part includes a first gear, a second gear and a first rotating shaft, the bottom of the mounting support is hinged to the rotating seat, and one side of the mounting bottom is fixed to the second gear, the second gear is meshed with the first gear, one end of the first rotating shaft passes through the rotating seat and is fixedly connected to the second gear, and the other end is provided with a crank handle, and the first rotating shaft is rotatably connected to the rotating seat.

[0012] The beneficial effect is that when in use, the crank is turned to drive the first gear to rotate, the first gear is meshed with the second gear, the rotation of the second gear drives the mounting support to rotate, and the atomizer tube placed on the mounting support to rotate, thereby adjusting the inclination angle of the atomizer tube, which helps to ensure the stability of the atomizer tube during use.

[0013] Preferably, as an improvement, the atomizer tube includes a barrel, an air pipe, a nozzle and a partition arranged in the barrel, the nozzle is fixedly installed in the center of the partition, an air hole connected to the air pipe is opened in the center of the partition, and a drug guiding part is also integrally formed on the partition, the drug guiding part and the nozzle are both conical, an annular cavity is provided between the nozzle and the bottom of the drug guiding part, and there is a gap between the drug guiding part and the upper part of the nozzle, and the annular cavity is connected to the connecting pipe.

[0014] The beneficial effects are as follows: through the above arrangement, the annular cavity is connected to the connecting tube, and when the medicine in the medicine bag is connected to the annular cavity and compressed air or oxygen is connected to the air supply pipe, the high-speed air flows through the end of the nozzle, driving the medicine in the annular cavity to flow out and break into mist, which is convenient for the child to inhale. At the same time, the annular cavity is provided in conjunction with a conical medicine guide part in the technical scheme. Even if the atomizer tube in the technical scheme is in an inclined state, the medicine liquid flows in the annular cavity and will not flow to the surroundings so that the medicine liquid cannot flow out through the medicine guide part. Through the above arrangement, the atomizer tube can be quickly converted into tiny droplets no matter what state it is in, which is convenient for the child to inhale; the medicine liquid can be fully utilized, waste can be reduced, and efficient atomization of the medicine liquid can be ensured during the entire treatment process.

[0015] Preferably, as an improvement, the inner cone array of the drug guiding portion has longitudinal stripes.

[0016] The beneficial effect is: through the above-mentioned arrangement, it is convenient to guide the medicine liquid, and the medicine liquid in the annular groove is evenly distributed on the inner cone surface of the medicine guiding part, avoiding that the droplets flowing up on one side are larger when tilted, resulting in a larger volume of mist droplets, which cannot reach the inhalation depth after entering the lungs or trachea.

[0017] Preferably, as an improvement, a sealing ring is provided at the bottom of the mounting groove, and a thread for connecting with the medicine bag is provided on the upper inner wall of the mounting groove; a horizontal bar is provided at the top outlet of the nozzle, and the horizontal bar is fixedly connected to the barrel.

[0018] The beneficial effects are: by setting the thread and the sealing ring, the sealing performance of the connection between the medicine bag and the rotary block can be effectively improved; by setting a horizontal bar at the top outlet of the nozzle, the medicine liquid brought out by the high-speed airflow can hit the horizontal bar, which can effectively improve the atomization efficiency of the medicine liquid.

[0019] Preferably, as an improvement, a limiting block is fixedly provided on the ear plate on the side of the rotating block close to the cylinder.

[0020] The beneficial effect is that the above arrangement can limit the angle of rotation of the rotary block toward one side of the cylinder body, so that when the nebulizer is used vertically, the rotary block can be swung until it abuts against the limit block to put the medicine bag in a vertical state, which is convenient for patients to use.

[0021] Preferably, as an improvement, a ratchet is keyed to the first rotating shaft, and the rotating seat is slidably provided with a latching tooth that can latch the ratchet.

[0022] The beneficial effect is that by setting the ratchet, when the inclination of the atomizer tube is adjusted downward, the ratchet rotates smoothly. After adjusting to the set position, the sliding teeth can clamp the main ratchet to prevent it from continuing to rotate, thereby fixing the position of the atomizer tube.
