Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to an atomizing inhalation device for elderly critically ill patients. Background Art

[0002] Medical problems of the elderly are becoming increasingly prominent; for elderly critically ill patients, due to the decline of the respiratory system, atomizing inhalation has become a commonly used treatment method for such patients.

[0003] Atomizing inhalation is a method of treating diseases by converting drugs into tiny particles through a specific device and allowing patients to inhale them into the respiratory tract and lungs; its main principle is to use high-speed airflow or ultrasonic energy to disperse drug solutions or suspensions into tiny droplets or particles; when the patient inhales, these tiny drug particles can enter the respiratory tract along with the airflow; generally, when the droplet diameter is 1 - 5μm, it can reach the respiratory tract and alveoli and exert the drug effect locally.

[0004] An atomizing inhalation device generally includes a medicine cup and a mouthpiece; the medicine cup includes an air flow regulating valve, a medicine pool, a nozzle, an air inlet, a primary screening aerosol particle baffle, etc., and its main function is to convert drugs into droplet particles; the mouthpiece includes a diversion tube, a secondary screening baffle, and an exhalation window, and its main function is for the patient to directly hold it in the mouth or connect a bent tube.

[0005] It should be noted that the medicine cup must always be kept in a vertical position, otherwise the liquid medicine will flow back; therefore, for most elderly critically ill patients lying flat, an additional long bent tube needs to be connected; currently, the working mode of the atomizer in hospitals is single, generally only having a duckbill-shaped mouthpiece; for patients who can hold it in the mouth by themselves, the mouthpiece can be directly used for atomizing inhalation; for patients who cannot hold it in the mouth, a face mask needs to be replaced for atomizing inhalation; for patients with a tracheal catheter inserted, a bent tube needs to be used to connect with the atomizer to carry out atomizing inhalation.

[0006] Generally, the atomizing inhalation time is 15 minutes, and the interface device is removed or replaced after use; for different patients, the atomizing inhalation device needs to be frequently replaced, which increases the workload of medical staff and the treatment time; for elderly critically ill patients, using a more convenient and fast atomizing inhalation device is extremely urgent and important for ensuring the life safety of patients. Summary of the Invention

[0007] Aiming at the deficiencies of the prior art, the present invention provides an atomizing inhalation device for elderly critically ill patients, which can easily switch between three working modes of a face mask, a mouthpiece, and a bent tube.

[0008] To achieve the above object, the present invention adopts the following technical solutions:

[0009] An atomizing inhalation device for elderly critically ill patients provided by the present invention includes: a flip-up face mask, a medicine cup connecting tube, and a telescopic mouthpiece; one end of the medicine cup connecting tube is connected to the output port of the medicine cup, and the other end is connected to the flip-up face mask; the flip-up face mask has two layers of bowl-shaped structures that can be extended and folded; the telescopic mouthpiece is a cylindrical structure with a middle hole and an outer fold.

[0010] Furthermore, the medicine cup connecting tube is a flexible connecting tube, and the bending angle can be adjusted.

[0011] Furthermore, the inside of the flip-up face mask is an inflatable structure to fit different facial structures.

[0012] Furthermore, when the telescopic mouthpiece is folded, the outer diameter increases, but the inner diameter remains unchanged.

[0013] The first aspect of the present invention provides a working mode of the flip-up face mask of the atomizing inhalation device; in this working mode, the telescopic mouthpiece is in a contracted state and is inside the face mask; the inner layer of the face mask is in a folded state, and the outer layer is in an extended state; there are threading holes on both sides of the face mask to facilitate wearing the face mask on the patient's face through a lanyard.

[0014] The second aspect of the present invention provides a mouthpiece working mode of the atomizing inhalation device; in this working mode, the inner layer of the face mask is in an extended state, and the outer layer is in a folded state, realizing the flipping of the face mask direction; at this time, the mouthpiece is outside the face mask, and the patient can perform mouthpiece atomizing inhalation.

[0015] The third aspect of the present invention provides a working mode of the telescopic elbow of the atomizing inhalation device; in this working mode, the face mask is in an everted state, and the mouthpiece is outside the face mask; at this time, the mouthpiece can be extended and bent according to the direction of the tracheal catheter, and without adjusting the patient's position, the atomizer can be connected to the tracheal catheter while ensuring that the medicine cup is always vertical.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] It has a working mode of one body with three functions, and can easily switch between the three working modes of the face mask, mouthpiece, and elbow through one device, and can be used immediately after switching; the structure of the present invention is simple, has strong adjustability, and is easy to operate, is suitable for different types of patients, and can greatly improve the atomizing inhalation efficiency of elderly critically ill patients; the device has a simple structure, low production cost, is easy to use, durable, and has excellent economic and social benefits.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The embodiment of the present invention provides an atomization inhalation device for elderly critically ill patients. As Figure 1 shown, it includes: a flip-up mask 1, a medicine cup connecting tube 2, and a telescopic mouthpiece 3; one end of the medicine cup connecting tube 2 is connected to the medicine cup outlet, and the other end is fixedly connected to the flip-up mask 1; the flip-up mask 1 has two layers of extendable and foldable bowl-shaped structures; the telescopic mouthpiece 3 is a cylindrical structure with a middle hole and an outer fold; after the medicine is atomized into an aerosol, it flows through the medicine cup connecting tube 2 from the medicine cup connecting outlet to the mask 1 and the telescopic mouthpiece 3.

[0025] For patients who can perform atomization inhalation by mouth, the mouthpiece working mode can be adopted. As Figure 2 shown; turn the mask 1 outward so that the telescopic mouthpiece 3 is on the outside of the mask 1, and the patient can adjust the length of the mouthpiece according to their own comfort for mouth atomization inhalation.

[0026] For patients who cannot perform atomization inhalation by mouth, the mask working mode can be adopted. As Figure 1 shown; contract the telescopic mouthpiece 3, turn the mask 1 to the left, and finally the mask is buckled on the patient's mouth and nose by medical staff, or after connecting the mask 1 with an elastic rope, wear the elastic rope on the patient's ears or head.

[0027] For patients with a tracheal catheter, the elbow connection working mode can be adopted. As Figure 3 shown; turn the mask 1 outward, stretch the telescopic mouthpiece 3, adjust the bending direction of the telescopic mouthpiece 3 according to the angle of the tracheal catheter, and finally nest the outlet of the telescopic mouthpiece 3 with the inlet of the tracheal catheter.

[0028] In some preferred embodiments, the outer shape of the face mask 1 can be designed as an ellipse or a water droplet shape to make it more conform to the shape of the human face.

[0029] In some preferred embodiments, the length and diameter of the medicine cup connecting tube 2 can be designed according to the limitations of the site and the medicine cup.

[0030] In some preferred embodiments, the diameter of the outlet section of the retractable mouthpiece 3 can be designed to be smaller than the diameter of the tracheal catheter opening and is made of an elastic material to adapt to the mouth shapes of different patients. At the same time, the retractable mouthpiece 3 can be tightly nested together when connected to the tracheal catheter to prevent the connecting tube from falling off due to the pulling of the pipeline.
