Description

Technical Field

[0001] The present disclosure relates to the field of medical treatment devices, and more precisely, to an oxygen supply and atomization device. Background Art

[0002] For patients suffering from chronic hypoxic lung diseases such as chronic obstructive pulmonary disease (COPD), long-term oxygen inhalation is usually required, which helps to relieve the hypoxic symptoms of the patients and improve the quality of life.

[0003] Currently, for patients in need of oxygen inhalation, the standard treatment method is still to deliver oxygen from an oxygen source through a nasal catheter. However, oxygen inhalation through a nasal catheter not only wastes a large amount of oxygen, but also causes nasal pain and irritation, and may exacerbate rhinitis and sinusitis.

[0004] Other oxygen inhalation methods, such as emergency cricothyrotomy and tracheostomy tube techniques, are generally limited to emergency situations where patients are suffocating due to airway obstruction, and are only applicable to patients with acute and chronic respiratory failure, and are not suitable for the long-term treatment of chronic lung diseases, so they are not suitable as a long-term oxygen therapy means for patients with chronic hypoxic lung diseases.

[0005] Moreover, for patients suffering from chronic hypoxic lung diseases such as chronic obstructive pulmonary disease (COPD), adjuvant drug administration treatment is usually also required. However, the existing drug administration methods generally have poor treatment effects and require separate drug administration, which is rather cumbersome. Summary of the Utility Model

[0040] The present disclosure provides an oxygen supply atomization device, which at least includes a tracheal catheter, an oxygen supply component, and an atomization component. Among them, the tracheal catheter is configured to be inserted into the trachea of a user, and is provided with an outlet end and an inlet end; the oxygen supply component is detachably communicated with the inlet end of the tracheal catheter, and is configured to supply oxygen to the trachea of the user through the outlet end of the tracheal catheter when the tracheal catheter is inserted into the trachea of the user; the atomization component is detachably communicated with the inlet end of the tracheal catheter, and is configured to supply a drug aerosol to the trachea of the user through the outlet end of the tracheal catheter when the tracheal catheter is inserted into the trachea of the user.

[0041] In this way, during the working process of the oxygen supply atomization device of the present disclosure, the doctor first inserts the tracheal tube into the trachea of the user. Then, the oxygen supply component can supply oxygen to the trachea of the user through the tracheal catheter, and the atomization component can supply a drug aerosol to the trachea of the user through the tracheal catheter. In this way, the oxygen supply atomization device of the present disclosure can simultaneously supply oxygen and a drug aerosol to the trachea of the user, so as to achieve the purpose of oxygen supply and atomization drug delivery.

[0042] For the sake of easy understanding, hereinafter, with reference to Figures 1 to 2 , in combination with an embodiment, the specific structure and working principle of the oxygen supply atomization device of the present disclosure will be described in detail.

[0043] As Figure 1 shown, the present disclosure provides an oxygen supply atomization device, which at least includes a tracheal catheter 10, an oxygen supply component 20, and an atomization component 30. Among them, the tracheal catheter 10 is configured to be inserted into the trachea of a user, and is provided with an outlet end and an inlet end; the oxygen supply component 20 is detachably communicated with the inlet end of the tracheal catheter 10, and is configured to supply oxygen to the trachea of the user through the outlet end of the tracheal catheter 10 when the tracheal catheter 10 is inserted into the trachea of the user; the atomization component 30 is detachably communicated with the inlet end of the tracheal catheter 10, and is configured to supply a drug aerosol to the trachea of the user through the outlet end of the tracheal catheter 10 when the tracheal catheter 10 is inserted into the trachea of the user. It can be understood that the oxygen supply component 20 can also supply oxygen-rich gas to the trachea of the user to achieve the purpose of oxygen supply.

[0044] In this way, during the working process of the oxygen supply atomization device of the present disclosure, the doctor first inserts the tracheal tube into the trachea of the user. Then, the oxygen supply component 20 can supply oxygen to the trachea of the user through the tracheal catheter 10, and the atomization component 30 can supply a drug aerosol to the trachea of the user through the tracheal catheter 10. In this way, the oxygen supply atomization device of the present disclosure can simultaneously supply oxygen and a drug aerosol to the trachea of the user, so as to achieve the purpose of oxygen supply and atomization drug delivery.

[0045] Specifically, the tracheal catheter 10 of the present disclosure can be inserted into the trachea of a patient under local anesthesia. Moreover, since the oxygen supply assembly 20 and the atomization assembly 30 are detachably connected to the inlet end of the tracheal catheter 10, the tracheal catheter 10 can be separated from the oxygen supply assembly 20 or the atomization assembly 30 when oxygen supply or atomization drug administration is not required, and the patient can adjust it according to needs.

[0046] For patients suffering from chronic hypoxic lung diseases such as chronic obstructive pulmonary disease (COPD), after the tracheal catheter 10 is implanted in a treatment place such as a hospital, oxygen supply and atomization drug administration can be regularly performed using the oxygen supply assembly 20 and the atomization assembly 30 at home or other places, which can provide long-term oxygen therapy and highly efficient atomization treatment to the patient, greatly relieve the patient's chronic hypoxia symptoms, improve the quality of life, and the operation method is relatively simple, without the need to use two sets of equipment for oxygen supply and atomization drug administration.

[0047] As Figure 2 shown, the oxygen supply and atomization device of the present disclosure further includes a main communication valve 40; the port of the main communication valve 40 is connected to the oxygen supply assembly 20 and the atomization assembly 30 through a first one-way valve 41, the second port of the main communication valve 40 is configured to be connected to the inlet end of the tracheal catheter 10, and the third port of the main communication valve 40 is connected to the outside through a second one-way valve 42; the first one-way valve 41 is configured to open when gas flows from the oxygen supply assembly 20 and / or the atomization assembly 30 to the tracheal catheter 10, and close when gas flows out of the tracheal catheter 10, and the second one-way valve 42 is configured to close when gas flows from the oxygen supply assembly 20 and / or the atomization assembly 30 to the tracheal catheter 10, and open when gas flows out of the tracheal catheter 10.

[0048] During the use of the oxygen supply and atomization device of the present disclosure, during the patient's inhalation process, the oxygen provided by the oxygen supply assembly 20 and / or the drug aerosol provided by the atomization assembly 30 can flow through the first one-way valve 41 and the tracheal catheter 10 into the trachea of the user. During the patient's exhalation process, the gas exhaled by the patient can be discharged to the outside through the second one-way valve 42 along the tracheal catheter 10. In this way, the gas exhaled by the patient will not contaminate the oxygen supply assembly 20 and the atomization assembly 30, and the secretions and sputum in the gas exhaled by the patient can also be continuously discharged to the outside through the second one-way valve 42, without blocking the outlet pipelines of the oxygen supply assembly 20 and the atomization assembly 30, ensuring the normal operation of the oxygen supply and atomization device of the present disclosure.

[0049] In one embodiment of the present disclosure, the oxygen supply and atomization device further includes a control unit configured to control the oxygen supply component 20 and / or the atomization component 30 to operate separately to supply oxygen or a drug aerosol to the user's trachea alone, or to supply both oxygen and a drug aerosol to the user's trachea simultaneously.

[0050] In this way, the oxygen supply and atomization device of the present disclosure can separately control the oxygen supply component 20 to supply oxygen to the user's trachea alone, or can separately control the atomization component 30 to supply a drug aerosol to the user's trachea, or can also simultaneously supply both oxygen and a drug aerosol to the user's trachea by using the oxygen supply component 20 and / or the atomization component 30, so as to better meet various treatment needs and improve the treatment experience.

[0051] As Figure 2 shown, in one embodiment of the present disclosure, the oxygen supply and atomization device of the present disclosure further includes a carbon dioxide sensor 50. The carbon dioxide sensor 50 is disposed in the pipeline of the second one-way valve 42 and is configured to detect the content of carbon dioxide in the gas exhaled by the user; the control unit is configured to control the operating parameters of the oxygen supply component 20 based on the content of carbon dioxide in the gas exhaled by the user. Since the carbon dioxide sensor 50 is disposed in the pipeline of the second one-way valve 42, in this way, the carbon dioxide sensor 50 can effectively detect the end-tidal carbon dioxide content of the patient, so as to effectively monitor the patient's respiratory conditions such as pulmonary ventilation and pulmonary blood flow. The control unit can control the operating parameters of the oxygen supply component 20 based on the content of carbon dioxide in the gas exhaled by the user, so as to improve the oxygen supply performance when the patient's hypoxia symptoms are relatively severe, and can appropriately reduce the oxygen supply performance when the patient's hypoxia symptoms are relatively mild, thereby promoting the patient's spontaneous breathing ability.

[0052] Specifically, in one embodiment of the present disclosure, the operating parameters of the oxygen supply component 20 at least include at least one of respiratory rate, inspiratory-expiratory ratio, tidal volume, minute ventilation volume, positive end-expiratory pressure, and oxygen concentration. Among them, the inspiratory-expiratory ratio refers to the proportion of the inspiratory time, the tidal volume refers to the amount of gas delivered by the oxygen supply component 20 to the patient, the minute ventilation volume refers to the total amount of gas delivered to the patient per minute, and the oxygen concentration refers to the oxygen concentration in the gas output by the oxygen supply component 20. Specifically, the control unit can adjust various parameters among the respiratory rate, inspiratory-expiratory ratio, tidal volume, minute ventilation volume, positive end-expiratory pressure, and oxygen concentration according to the patient's respiratory conditions.

[0053] As Figure 2As shown, in an embodiment of the present disclosure, the atomization assembly 30 includes a drug storage chamber 31, a delivery pump 32, and an atomization unit 33. The delivery pump 32 is configured to pump the liquid drug in the drug storage chamber 31 to the atomization unit 33, and the atomization unit 33 is configured to form a drug aerosol from the liquid drug. That is, during the operation of the oxygen supply atomization device of the present disclosure, the delivery pump 32 pumps the liquid drug in the drug storage chamber 31 to the atomization unit 33. After the atomization unit 33 forms a drug aerosol from the liquid drug, it can be input into the trachea of the user through the tracheal catheter 10.

[0054] Specifically, in an embodiment of the present disclosure, the atomization unit 33 is one of an ultrasonic atomization unit 33, a compression atomization unit 33, or a mesh atomization unit 33. Among them, the drug aerosol droplets generated by the ultrasonic atomization unit 33 are small and relatively uniform; the compression atomization unit 33 can generate a drug aerosol with a higher concentration, and the aerosol stability is relatively high; the mesh atomization unit 33 has a large fog output, and the structure is simple and easy to maintain. Specifically, an appropriate atomization unit 33 can be selected according to the specific properties of the liquid drug.

[0055] It can be understood that, as Figure 2 shown, in an embodiment of the present disclosure, the atomization assembly 30 further includes a jet pump 34. The jet pump 34 is configured to form a jet airflow to eject the drug aerosol from the outlet end of the tracheal catheter 10. Since the jet airflow formed by the jet pump 34 can eject the drug aerosol from the outlet end of the tracheal catheter 10, it can ensure that the drug aerosol is evenly distributed in the patient's trachea, thereby making the drug administration more uniform.

[0056] In an embodiment of the present disclosure, the oxygen supply atomization device of the present disclosure further includes a negative pressure suction device 60. The negative pressure suction device 60 is disposed at the outlet of the pipeline of the second one-way valve 42 and is configured to suck out the secretions in the user's respiratory tract when the tracheal catheter 10 is installed in the user's respiratory tract. In this way, the secretions and sputum in the gas exhaled by the patient can be continuously discharged from the second one-way valve 42 to the external negative pressure suction device 60, while preventing the patient's respiratory tract from being blocked by excessive sputum.

[0057] It can be understood that, in an embodiment of the present disclosure, the inner diameter range of the tracheal catheter 10 is from 0.9 mm to 20 mm. Among them, for patients who do not require sputum suction, a tracheal catheter 10 with a smaller inner diameter can be selected, for example, a tracheal catheter 10 with an inner diameter of 0.9 mm to 5 mm. In this way, the usage barrier for the patient is smaller. For patients who need to perform sputum suction, a tracheal catheter 10 with a larger inner diameter can be selected, for example, a tracheal catheter 10 with an inner diameter of 5 mm to 20 mm, so as to facilitate sucking out the sputum in the patient's trachea.

[0058] The embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, the practical application, or the improvement of technology in the market, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
