Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an atomizing drug delivery device for pediatric respiratory medicine. Background Art

[0002] An atomizing inhaler is a device used for treating upper respiratory diseases and belongs to medical devices. It is mainly used for treating various upper and lower respiratory system diseases and is an important and effective treatment method in the treatment of respiratory diseases. The atomizing inhaler 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.

[0003] A common atomizing drug delivery device for pediatric respiratory medicine usually has a cavity for adding medicine in the atomizing box. Since the box body is closed, it is impossible to calculate the amount of the injected liquid medicine, which is inconvenient for doctors to quantitatively control the amount of the liquid medicine. In addition, a relatively long hose is arranged at the air outlet end of the atomizer, and there is no specific storage device, so the hose is likely to fall to the ground and cause pollution. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose an atomizing drug delivery device for pediatric respiratory medicine. Through the quantitative mechanism, the amount of the added liquid medicine can be known, which is convenient for doctors to quantitatively control the amount of the liquid medicine. Through the storage mechanism, the too-long hose is restricted and stored, ensuring the cleanliness of the hose.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

The sliding grooves are arranged on the inner walls of the front and rear sides of the cavity, and the sliding rod is slidably connected to the inside of each sliding groove;

[0008] The storage mechanism includes a storage bag, a round rod, a ring and a limiting plate. The rear end of the storage bag is fixedly connected to the front end of the box body. The rear ends of the round rods are fixedly connected to the front end of the box body and are located above the storage bag. The outer circumferences of the round rods are slidably connected to the rings. The bottom ends of the rings are fixedly connected to the front top ends of the storage bag, and the front ends of the round rods are fixedly connected to the limiting plates.

[0009] Further, the metering mechanism further includes a glass plate and scale lines. The glass plate is fixedly connected inside the front chute of the box body, and scale lines are provided on the front end surface of the glass plate.

[0010] Further, the metering mechanism further includes rollers. The rollers are arranged at both ends of the sliding rod, and the outer circumferences of the rollers are all slidably connected to the inner wall of the chute.

[0011] Further, the storage mechanism further includes that one end of each spring is fixedly connected with a ring, the other end of each spring is fixedly connected to the front end of the box body, and the springs are all wound around the outer circumference of the round rod.

[0012] Further, the storage mechanism further includes that both ends of the cross bar are fixedly connected to the outer circumference of the ring, and a handle is fixedly connected to the front end of the cross bar.

[0013] Further, a connection head is provided at the upper left part of the front end of the box body. The front end of the connection head is fixedly connected to one end of a hose, and the other end of the hose is fixedly connected to a mask.

[0014] Further, the mask can be replaced by a fixing frame, an outer arc plate, side arc plates, a filtering mechanism and an air distribution mechanism. An outer arc plate is fixedly installed at the upper end of the fixing frame. Two side arc plates are fixedly installed on both sides of the outer arc plate. A filtering mechanism is fixedly installed inside the side arc plates. An air distribution mechanism is fixedly installed inside the fixing frame;

[0015] The filtering mechanism includes a filter valve pipe, a semi-circular plate, a first filter plate, a fixed vertical plate, a fan blade and a second filter plate. A filter valve pipe is fixedly installed at the lower end inside the side arc plate. A first filter plate and a second filter plate are fixedly installed on the inner wall of the filter valve pipe in sequence. A fixed vertical plate is fixedly installed in the middle of the inner wall of the filter valve pipe. A fan blade is movably connected to the side of the fixed vertical plate.

[0018] The present invention has the following beneficial effects:

[0019] 1. In the present invention, liquid medicine is injected into the cavity through the liquid inlet pipe. After the liquid medicine enters the cavity, it will push the floating ball to float upward, and then drive the sliding rod to move upward. Through the glass plate, the scale line aligned with the sliding rod can be observed, and thus the amount of liquid medicine added can be known, which is convenient for doctors to quantitatively control the amount of liquid medicine.

[0020] 2. In the present invention, when holding the handle and pulling the cross bar forward, the movement of the cross bar drives the ring to move, and the movement of the ring will pull the storage bag to open. At this time, the excess hose can be put into the interior of the storage bag. When the handle is released, the spring contracts and pulls the ring to move backward, realizing the contraction of the mouth of the storage bag, restricting the hose in the storage bag, avoiding the situation that the hose is too long and falls to the ground, and ensuring the cleanliness of the hose.

[0021] 3. By providing a filtering mechanism, when breathing through the mouth and nose, air is introduced from the outside into the wearing mechanism through the filter valve pipe. After the outside air enters the filter valve pipe, it is filtered by the cooperation of the first filter plate and the second filter plate. At the same time, with the cooperation of the fan blades on the side of the fixed vertical plate, the air entering the filter valve pipe can be accelerated, ensuring the air required during the treatment process and also filtering the air entering the wearing mechanism.

[0022] 4. By providing an air distribution mechanism, after connecting the nebulizer to the connecting pipe and starting the nebulizer after the connection is completed, the mist is introduced into the wearing mechanism through the connecting pipe. Using several curved holes in the conical cover, the mist is dispersed, improving the dispersion range of the mist and enhancing the effect of atomization treatment.

[0036] The metering mechanism 4 includes a sliding rod 401, a sliding groove 402, a balance piece 405 and a floating ball 406. The bottom end of the sliding rod 401 is fixedly connected to the top end of the balance piece 405. The balance piece 405 can ensure the balanced floating of the sliding rod 401 and avoid jamming. A number of floating balls 406 are evenly distributed at the bottom end of the balance piece 405. The sliding grooves 402 are arranged on the inner walls of the front and rear sides of the cavity 9. The sliding rod 401 is slidably connected to the inside of each sliding groove 402. The metering mechanism 4 further includes a glass plate 403 and scale lines 404. The glass plate 403 is fixedly connected to the inside of the front sliding groove 402 of the box body 1. Scale lines 404 are arranged on the front end surface of the glass plate 403. When the liquid medicine is injected into the cavity 9 from the liquid inlet pipe 2, the liquid medicine will push the floating balls 406 to float after entering the cavity 9, and then drive the sliding rod 401 to move upward. The scale line 404 aligned by the sliding rod 401 can be observed through the glass plate 403, and then the amount of the added liquid medicine can be known, which is convenient for the doctor to quantitatively control the amount of the liquid medicine. The metering mechanism 4 further includes rollers 407. The rollers 407 are arranged at both ends of the sliding rod 401. The outer circumference of each roller 407 is slidably connected to the inner wall of the sliding groove 402.

Hold the handle 707 and pull the cross bar 706 forward. The movement of the cross bar 706 drives the movement of the rings 704. The movement of the rings 704 will pull the storage bag 701 open. At this time, the excess hose 6 can be put into the inside of the storage bag 701. Release the handle 707, and the contraction of the springs 705 will pull the rings 704 backward, realizing the contraction of the mouth of the storage bag 701 and restricting the hose 6 in the storage bag 701, avoiding the situation that the hose 6 is too long and falls to the ground, and ensuring the cleanliness of the hose 6.

[0038] Working principle: Inject the liquid medicine into the cavity 9 from the liquid inlet pipe 2. After the liquid medicine enters the cavity 9, it will push the suspension ball 406 to float upward, and then drive the slide rod 401 to move upward. Through the glass plate 403, the scale line 404 aligned by the slide rod 401 can be observed, and then the amount of the added liquid medicine can be known, which is convenient for the doctor to quantitatively control the amount of the liquid medicine. Hold the handle 707 and pull the cross bar 706 forward. The movement of the cross bar 706 drives the ring 704 to move. The movement of the ring 704 will pull the storage bag 701 to open. At this time, the redundant hose 6 can be placed inside the storage bag 701. Release the handle 707, and the contraction of the spring 705 will pull the ring 704 to move backward, realizing the contraction of the mouth of the storage bag 701 and restricting the hose 6 in the storage bag 701, avoiding the situation that the hose 6 is too long and falls to the ground, and ensuring the cleanliness of the hose 6.
