Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medical atomizer, more specifically, a compressed atomizer providing drug mist according to breathing state. BACKGROUND

[0002] In recent years, with the increase of respiratory system diseases, more and more patients use inhalation therapy, so the demand for medical atomizers has also increased significantly. The atomizer atomizes the liquid medicine into small particles, which is inhaled into the respiratory tract and lungs by the patient, so as to directly apply medicine to the treatment site, improve the absorption of medicine, and reduce the side effects of medicine, such as treating cold, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis and other diseases in the trachea, bronchus, alveoli and chest cavity. Therefore, atomization therapy is also an important and effective treatment method for respiratory system diseases.

[0003] The compressed atomizer uses compressed air to form a high-speed airflow through a small nozzle, and the negative pressure generated drives the liquid medicine to be sprayed onto the obstruction. Under the high-speed impact, the liquid droplets are scattered around and become mist particles that are sprayed out of the air pipe. The mist spraying mode of such compressed atomizers is active, and in actual use, patients wear masks to inhale the atomized liquid. During the patient's exhalation, some of the liquid medicine will be discharged from the exhalation hole of the mask, resulting in waste of some of the liquid medicine. Moreover, since the atomizer is always spraying mist, when the amount of mist sprayed is greater than the amount of liquid medicine inhaled by the patient, some of the liquid medicine will also overflow from the exhalation hole or the gap between the mask and the patient's face during the patient's inhalation. This results in a low actual atomization absorption rate of the liquid medicine, greatly reducing the treatment effect.

[0004] To solve the above problems, some technical solutions have appeared in the prior art that use breathing detection to control the operation of the atomizer, with the purpose of providing drug mist when the patient inhales and stopping the supply of drug mist when the patient exhales, thereby reducing the waste of liquid medicine. For compressed atomizers, an electromagnetic valve is generally arranged between the air compressor and the atomizing cup, and the breathing detection is used to control the opening and closing of the electromagnetic valve, so as to achieve the purpose of opening the high-pressure gas channel when inhaling and closing the high-pressure gas channel when exhaling. However, due to the high pressure of the compressed air generated by the air compressor, when the electromagnetic valve closes and blocks the high-pressure gas channel, the high-pressure gas will impact the air-tight mechanism of the air compressor, the electromagnetic valve and the pipeline, which can easily damage the air compressor itself and the electromagnetic valve, and can also cause the pipeline connection to loosen, thereby affecting the working stability and service life of the atomizer.

DETAILED DESCRIPTION

[0041] In order to further understand the content of the present application, the present application is described in detail in combination with the drawings and embodiments.

[0042] [Embodiment 1]

[0043] Figures 1 to 3 Figure 1 shows the structural principle and accessories of the compressed nebulizer of the present embodiment. Referring to Figures 1 to 3As shown, this embodiment of a compression nebulizer that provides drug mist based on breathing status includes a breathing mask 1, a breathing sensor 2, a control module 3, an air compressor assembly 8, a nebulizer cup 9, and a reversing valve 4. The air compressor assembly 8 is driven by a motor and is connected to the nebulizer cup 9 for nebulizing the drug. The breathing mask 1 is connected to the mist outlet of the nebulizer cup 9 for exhalation and inhalation. The breathing sensor 2 is connected to the breathing mask 1 to detect the exhalation or inhalation state within the breathing mask 1. The control module 3 is communicatively connected to the breathing sensor 2. The control module 3 is used to process the detection signal fed back by the breathing sensor 2. The reversing valve 4 has a first valve path and a second valve path that are controlled and switched by the control module 3. The first valve path is located between the high-pressure gas channel of the air compressor assembly 8 and the nebulizer cup 9, and the second valve path is located between the air compressor assembly 8 and the atmosphere. The control module 3 controls the reversing valve 4 to operate according to the exhalation or inhalation state detected by the breathing sensor 2: when inhaling, the second valve path is disconnected and the first valve path is opened to generate drug mist; when exhaling, the first valve path is disconnected and the second valve path is opened to connect the air compressor assembly 8 to the atmosphere. Specifically, the patient wears a breathing mask 1, and the airflow is detected by a breathing sensor 2, which feeds back to the control module 3. The control module 3 determines the patient's inhalation and exhalation states. When the patient inhales, the first valve of the reversing valve 4 is opened, and the high-pressure gas generated by the air compressor assembly 8 enters the nebulizer cup 9 to atomize the medication, which is then inhaled by the patient through the breathing mask 1. When the patient exhales, the first valve of the reversing valve 4 closes, at which point the nebulizer cup 9 stops producing medication mist, and the second valve opens, allowing the air compressor to exhaust to the atmosphere. In this way, medication mist is produced when the patient inhales and stops when exhaling, reducing medication waste and ensuring the effectiveness of nebulization therapy. Furthermore, during exhalation, the air compressor is open to the atmosphere, reducing the impact of high-pressure gas on the air compressor's sealing mechanism, reversing valve, and pipelines, thus ensuring the operational stability and service life of the compressor nebulizer.

[0044] Because air compressors tend to generate significant noise during the exhaust process, therefore... Figure 2 As shown, in a preferred embodiment, a silencer 14 is also provided at the air outlet of the reversing valve 4 that is open to the atmosphere. The silencer 14 can effectively reduce the noise generated by the air compressor assembly 8, which is beneficial to improving the noise environment of the nebulization treatment. Of course, the silencer 14 is optional. If the exhaust noise of the air compressor is within an acceptable range, the silencer 14 may not be installed.

[0045] The reversing valve 4 described above can adopt a combined valve design or an integrated valve design. For example, when a combined valve is adopted, one on-off electromagnetic valve can be arranged on each of the first valve path and the second valve path, and the two on-off electromagnetic valves are always in a state of one closed and one open, and the switching of the two valve paths of the reversing valve 4 is realized through the control of the two on-off electromagnetic valves. When an integrated valve is adopted, the reversing valve 4 can be a three-way electromagnetic valve. The embodiment preferably adopts a three-way electromagnetic valve design, which is simple and compact in structure, stable and reliable in work, fast in switching action response speed, and small in drug mist delivery hysteresis, thereby ensuring the accuracy and timeliness of the switching action of the drug mist delivery. Specifically, the three-way electromagnetic valve has one air inlet and two air outlets, and the air inlet is connected to different air outlets through the on-off electric control of the three-way electromagnetic valve. Specifically, the air inlet of the three-way electromagnetic valve is connected to the air outlet of the air compressor assembly 8, one air outlet of the three-way electromagnetic valve is connected to the atomizing cup 9, and the other air outlet is connected to the atmosphere. In the inhalation state, the three-way electromagnetic valve connects the air compressor assembly 8 and the atomizing cup 9, and atomizes the liquid medicine for the patient to inhale; in the exhalation state, the three-way electromagnetic valve connects the air compressor assembly 8 and the atmosphere. In this way, the air compressor assembly 8 can be consistently in a working state, and the on-off of the high-pressure air is controlled by the three-way electromagnetic valve, which is faster in action response speed than directly controlling the start and stop of the air compressor, and can more accurately and timely realize the switching of the drug mist delivery in cooperation with the breathing sensor 2. Moreover, the air compressor can be connected to the atmosphere during exhalation, reducing the impact of high-pressure gas on the compressor, the reversing valve 4 and the pipeline, and ensuring the working stability and service life of the atomizer.

[0046] As shown in Figure 2 and Figure 3 In the embodiment, the breathing mask 1 and the mist outlet of the atomizing cup 9 are connected through the three-way joint 7, and the breathing sensor 2 is connected to the three-way joint 7 through the hose 6. Specifically, the three-way joint 7 has an air inlet and outlet and a bypass interface 7-1, the mist outlet of the atomizing cup 9 is connected to the air inlet of the three-way joint 7, the air outlet of the three-way joint 7 is connected to the air inlet of the breathing mask 1, and the bypass interface 7-1 is connected to the breathing sensor 2 through the hose 6. In this way, the existing breathing mask 1 and atomizing cup 9 can be used, and the development and investment cost of the breathing mask 1 and the atomizing cup 9 can be reduced. Of course, the breathing mask 1 and the mist outlet of the atomizing cup 9 can also be directly connected, and at this time, a breathing detection port can be arranged on the breathing mask 1, and the breathing sensor 2 can be connected to the breathing detection port through the hose 6.

[0047] In the embodiment, the detection element of the breathing sensor 2 is an ultrasonic probe or an infrared probe, which is less affected by the temperature and humidity of the breathing air, has good working stability, and can quickly and accurately detect the breathing state. For details, refer to Figure 4 and Figure 5As shown, the respiration sensor 2 comprises a detection tube 2-1, and two different position tube openings 2-2 are provided on the detection tube 2-1, one of which is connected to the breathing mask 1, and the other is connected to the atmosphere, and a flow detection element 2-3, i.e. an ultrasonic probe or an infrared probe, is arranged at each of the two tube openings 2-2. The respiratory airflow can flow in the detection tube 2-1, and the airflow signals detected by the two detection elements have a sequence due to the different detection positions of the two detection elements, and this sequence reflects the flow direction of the airway in the detection tube 2-1, i.e. reflects the change of exhalation or inhalation. The control module 3 is in communication connection with the respiration sensor 2, and the two detection elements of the respiration sensor 2 feed the detection signals to the control module 3, which processes and analyzes the detection signals.

[0048] The compressed nebulizer according to the respiration state of the embodiment is connected between the reversing valve 4 and the atomizing cup 9 through the first air pipe 10, and the air compressor assembly 8 is connected between the reversing valve 4 and the air compressor assembly 8 through the second air pipe 13.

The breathing mask 1, the atomizing cup 9 and their pipelines are disposable supplies, and corresponding interfaces can be provided on the main machine shell 5 to facilitate the connection of the atomizing cup 9 and the reversing valve 4 and the connection of the breathing mask 1 and the respiration sensor 2. When the muffler 14 is provided, the muffler 14 is also integrated in the main machine shell 5. In addition, a conversion switch 11 for converting the continuous mist output mode of the nebulizer to the breathing mask 1 or the intermittent mist output mode according to the respiration state is arranged on the main machine shell 5, the conversion switch 11 is in electrical connection with the control module 3, and the conversion switch 11 can control the conversion of the continuous mist output mode of the nebulizer to the breathing mask 1 or the intermittent mist output mode according to the respiration state, and the conversion switch 11 can be flexibly selected according to the use needs to meet the use needs of different patients. Of course, a start switch 12 and a power plug are also arranged on the main machine shell 5, the start switch 12 can be used to control the start and stop of the air compressor, and the power plug is used to power the nebulizer.
