[0001] The invention relates to the technical field of respiratory nursing, in particular to an atomizing spraying device for respiratory nursing. Background Art

[0002] In the treatment of respiratory diseases, nebulized inhalation therapy is an important method of local drug delivery. It converts drugs into tiny droplets or particles, allowing the drugs to directly enter the respiratory tract and lungs, thereby increasing local drug concentrations and reducing systemic side effects. As the core tool for implementing this therapy, the development of nebulized spray equipment is closely related to the needs of respiratory care.

[0003] However, although commonly used atomizing sprayers can achieve optimal utilization of the liquid medicine by controlling the concentration of the liquid medicine, as the atomized liquid medicine is continuously produced, part of it is absorbed by the human body, and the other part will escape into the air, resulting in waste of the liquid medicine.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention is provided with a mist pipe, a pre-bent film and a fixed valve seat. Since the initial state of the pre-bent film is to block the air inlet port of the mist pipe, when the patient inhales, the pre-bent film is stretched toward one end of the nozzle under the action of air pressure. At this time, the air inlet port of the mist pipe is opened, so that the medicine in the atomization pipe can be delivered to the patient through the mist pipe. When the patient exhales, the airflow entering the atomization pipe will assist the pre-bent film to reset, thereby reducing the patient's exhaled airflow entering the atomization pipe and contaminating the medicine. At the same time, it can also enable the precise delivery of the medicine and reduce the waste of medicine escaping. The fixed valve seat limits the deformation of the pre-bent film, thereby preventing the pre-bent film from excessively deforming inward.

[0019] The present invention is provided with a screen membrane, which can be adjusted by aligning the lever and the connecting rod, thereby controlling the fixed position of the screen membrane and further refining the atomized particles. The connecting baffle can also block the rotating notch of the baffle to prevent the drug solution from escaping from the notch. At this time, the atomization degree of the drug solution is poor, and the effect after being absorbed by the patient is poor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] See also Figure 1-Figure 5 The present invention provides a technical solution: a respiratory care atomizing spray device, comprising an atomizing tube 8 and a liquid medicine tube 10, and further comprising:

[0028] The air pump 1 has a piston inside that can compress air to generate high-speed airflow. A connecting pipe 7 is provided on one side of the air pump 1, which is connected to the liquid medicine pipe 10 through the connecting pipe 7.

[0029] The spray tube 4 has a pre-bent film 22 fixedly connected to its interior and a mist pipe 9 fixedly connected to its side. When no airflow is generated, the pre-bent film 22 blocks the air inlet port of the mist pipe 9.

[0030] The trachea 15 and the liquid suction tube 20 can be used to atomize the liquid medicine;

[0031] The suction nozzle 5 is movably connected to one end of the spray tube 4 and is used for absorbing the liquid medicine.

[0032] Furthermore, one end of the spray tube 4 passes through and is fixedly connected to one side of the atomizing tube 8. A fixed column 11 is movably installed inside the atomizing tube 8. The top of the fixed column 11 is fixedly connected to a tube cover 3. The tube cover 3 is movably inserted into the top of the atomizing tube 8. The bottom of the fixed column 11 is fixedly connected to a fixed plate 13. The fixed plate 13 is semicircular. The top of the fixed plate 13 is fixedly connected to a baffle 19. The bottom of the fixed plate 13 is fixedly connected to a fixed block 28, which can be used to atomize the liquid medicine. The pipette 20 is fixedly connected to the bottom end of the fixed block 28, and the pipette 20 is movably sleeved on the outside of the trachea 15.

[0033] Furthermore, the interior of the medicine liquid tube 10 is fixedly connected to a fixed base plate 21, the bottom of the fixed base plate 21 is passed through and fixedly connected to a fixed tube 17, the bottom of the air pipe 15 is passed through and fixedly connected to the top of the fixed base plate 21, the top of the fixed base plate 21 is fixedly connected to a liquid collecting hopper 16, and the top of the medicine liquid tube 10 is fixedly connected to a stud ring 14. The separate design facilitates the operation of adding medicine, and the stud ring 14 is threadedly connected to the bottom of the atomizing tube 8.

[0034] Furthermore, the tube cover 3 and the internal part of the fixed column 11 are rotatably connected with a connecting rod 26, the bottom of the connecting rod 26 is fixedly connected with a fixed inner ring 29, the outer side of the fixed inner ring 29 is fixedly connected with a screen membrane 12, the side of the screen membrane 12 away from the fixed inner ring 29 is fixedly connected with a fixed outer ring 18, the top of the connecting rod 26 is fixedly connected with a shift rod 6, the fixed inner ring 29 is rotatably connected to the side of the fixed column 11, the fixed outer ring 18 is rotatably connected to the inner wall of the atomizing tube 8, the outer side of the fixed inner ring 29 and the inner side of the fixed outer ring 18 are fixedly connected with a connecting baffle 30, which can perform screening operations on the atomized liquid medicine to further refine the liquid medicine particles, and the connecting baffle 30 is rotatably connected to the side of the baffle 19.

[0035] Furthermore, the internal thread of the tube cover 3 is connected to an adjusting screw 24, which is rotatably connected to the inside of the fixed column 11, the fixed plate 13 and the fixed block 28. The top of the adjusting screw 24 is fixedly connected to the knob 2, and the bottom of the adjusting screw 24 is fixedly connected to the adjusting core block 25. The width of the channel at the top of the pipette 20 can be adjusted to achieve control of the flow rate of the liquid medicine.

[0036] Furthermore, a fixed valve seat 23 is fixedly connected to the inner wall of the spray tube 4, which limits the deformation of the pre-bent film 22 and prevents the pre-bent film 22 from being excessively deformed inward.

[0037] Furthermore, one end of the connecting tube 7 is movably connected to the air outlet end of the air pump 1, which can increase the high-speed airflow for atomization, and the end of the connecting tube 7 away from the air pump 1 is movably connected to the bottom of the fixed tube 17.

[0038] Furthermore, a fixed block 27 is fixedly connected to the bottom of the tube cover 3 to further improve the stability of the tube cover 3 when it is fixed. A clamping groove is opened on the top of the atomizing tube 8, and the fixed block 27 is movably clamped to the inner wall of the clamping groove.

[0039] Working principle: First, remove the liquid medicine tube 10 by rotating the stud ring 14, and then pour the liquid medicine into the liquid collecting hopper 16. After pouring, re-rotate the liquid medicine tube 10 to fix it to the bottom of the atomizing tube 8, and then connect the air pump 1 and the fixed tube 17 through the connecting tube 7. At this time, connect the liquid suction tube 20 to the air pipe 15 through the tube cover 3, and then rotate the tube cover 3 so that the fixed block 27 is clamped into the clamping groove at the top of the atomizing tube 8. After installation, Figure 1 As shown, the suction nozzle 5 is then sleeved onto the spray tube 4. After the suction nozzle 5 is sleeved, the fixed direction of the screen membrane 12 can be adjusted according to the size of the particles to be atomized. If it is necessary to filter finer particles of the liquid medicine, the screen membrane 12 can be rotated 180 degrees by the lever 6 and the connecting rod 26 so that the screen membrane 12 is located on the side away from the spray tube 4.

[0040] Then the air pump 1 can be started, and the air pump 1 delivers airflow to the atomizing tube 8 through the connecting tube 7 and the air pipe 15. According to Bernoulli's theorem, the liquid medicine channels on both sides of the pipette 20 and the blocking operation of the fixed block 28 are used to make the airflow drive the liquid medicine to collide with the fixed block 28 to break and atomize. The floating liquid medicine will be discharged from the spray tube 4 along the airflow and absorbed by the patient, while the non-floating liquid medicine will be blocked by the fixed plate 13 and then fall back into the liquid collecting hopper 16 to be atomized. The concentration of the liquid medicine can be adjusted by rotating the knob 2. The knob 2 can adjust the distance between the regulating core block 25 and the top of the pipette 20 through the adjusting screw 24. By controlling the size of the channel, the flow rate of the liquid medicine can be controlled.

[0041] The pre-bent film 22 inside the spray tube 4 can block the air inlet port of the mist tube 9 in its initial state, and the end away from the suction nozzle 5 is the air inlet port of the mist tube 9. Therefore, when the patient inhales, under the action of air pressure, the pre-bent film 22 is stretched toward one end of the suction nozzle 5. At this time, the air inlet port of the mist tube 9 is opened, so that the medicine in the atomization tube 8 can be delivered to the patient through the mist tube 9. The suction nozzle 5 can also be replaced with an absorption device in the form of a mask. When the patient exhales, the airflow entering the spray tube 4 will assist the pre-bent film 22 to reset, thereby reducing the patient's exhaled airflow entering the atomization tube 8, and also allowing the precise delivery of the medicine. The fixed valve seat 23 at one end of the pre-bent film 22 limits the deformation of the pre-bent film 22, thereby preventing the pre-bent film 22 from excessively deforming inward.
