Description

Technical Field

[0001] This utility model relates to the field of respiratory assist device technology, specifically a high-pressure oxygen nebulization synchronous respiratory assist device. Background Technology

[0002] Hyperbaric oxygen chambers often use synchronized respiratory assist devices (RADs). These devices are typically connected to an oxygen source. The patient wears a mask and inhales oxygen. A high-speed oxygen flow atomizes the medication, creating a mist-like suspension that is then inhaled into the respiratory tract, achieving the therapeutic effect. The basic principle is that a high-speed oxygen flow carries the medication out through an adjacent tube. The inhaled medication is atomized into fine droplets by the oxygen flow, creating an aerosol that enters the respiratory tract with the patient's respiration, thus achieving a therapeutic effect.

[0003] However, current respiratory assist devices usually require a certain amount of medication to be pre-injected into the mixer before being sprayed out through oxygen atomization. The disadvantage is that when the amount of medication injected is too small, the treatment effect will be poor. The process of injecting medication depends on the operator's subjective judgment. Therefore, when the amount of medication is insufficient, the mask needs to be removed and medication needs to be added to the mixer, which is very inconvenient.

[0004] Therefore, we propose a hyperbaric oxygen nebulizer-assisted breathing device to address the problems mentioned above.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.

[0046] Example 1:

[0047] Please see Figures 1-3A hyperbaric oxygen nebulizer-assisted breathing device includes: a connecting end 1, an air delivery tube 2, a mixer 3, a sleeve 4, a mask 5, and a nebulizer head 6. The connecting end 1 and the mixer 3 are connected through the air delivery tube 2. The sleeve 4 is located outside the mixer 3, the mask 5 is located on the sleeve 4, and the nebulizer head 6 is located on the mask 5 and connected to the mixer 3. A liquid storage tank 7 is fixedly installed on the sleeve 4. The liquid storage tank 7 is provided with a liquid inlet assembly 8. The liquid inlet assembly 8 includes an injection tube 81, which is fixedly installed on the liquid storage tank 7. A first connecting tube 82 and a second connecting tube 83 are fixedly installed on the injection tube 81. The first connecting tube 82 is connected to the liquid storage tank 7, and the second connecting tube 83 is connected to the mixer 3. One-way connecting tubes 84 are provided on both the first connecting tube 82 and the second connecting tube 83, and the one-way connecting directions of the two one-way connecting tubes 84 are opposite. A piston rod 85 is also movably installed in the inner cavity of the injection tube 81 and is sealed to the injection tube 81. The liquid storage tank 7 is also provided with a liquid inlet tube 9.

[0048] In the above technical solution, the one-way connecting pipe 84 connected to the first connecting pipe 82 only connects the injection tube 81 to the first connecting pipe 82 when the piston rod 85 is pulled, and the one-way connecting pipe 84 connected to the second connecting pipe 83 only connects the injection tube 81 to the second connecting pipe 83 when the piston rod 85 is pushed.

[0049] By adopting the above scheme, when using the medicine, first inject the medicine into the storage tank 7 through the inlet pipe 9, then repeatedly extract the medicine into the mixer 3, and then carry it out through the oxygen flow. When injecting the medicine, inject it in small amounts and multiple times to avoid having to remove the mask and re-inject the medicine when the amount of medicine is too small.

[0050] Another advantage is that the small, frequent injection method can avoid injecting too much medication, preventing patients from inhaling excessive amounts of medication, and also avoiding waste of medication.

[0051] Please see Figure 3 and Figure 4 The one-way connecting tube 84 includes a tapered tube 841, and an elastic rope 842 is fixedly installed in the inner cavity of the tapered tube 841. The tapered tube 841 includes an end face 841a and an end face 841b. A blocking ball 843 is also provided in the inner cavity of the tapered tube 841 between the end face 841b and the elastic rope 842. The end face 841a of the tapered tube 841 installed on the first connecting tube 82 faces the injection tube 81, and the end face 841b of the tapered tube 841 installed on the second connecting tube 83 faces the injection tube 81. The injection tube 81 is also provided with a scale 86 and a handle 10.

[0052] The injection tube 81 is made of transparent material. When injecting the drug solution through the injection tube 81, the amount extracted can be observed through the scale 86, thereby achieving quantitative extraction and injection.

[0053] Please see Figure 5 The connecting end 1 includes an air inlet cylinder 11, which is provided with a first insertion tube 12, and the end of the first insertion tube 12 is located at the bottom of the inner cavity of the air inlet cylinder 11; the air inlet cylinder 11 is also provided with a second insertion tube 13, and the air guide tube 2 is connected to the second insertion tube 13; the top of the air inlet cylinder 11 is provided with a flow monitoring bottle 14, which is provided with a float ball 16; the first insertion tube 12 is provided with a control valve 15.

[0054] Example 2:

[0055] Please see Figure 6 and Figure 7 and combined Figure 2 In comparison, based on embodiment 1, the mask 5 includes a mask body 51, a fixed section 52 is fixedly installed on the mask body 51, the fixed section 52 is connected to the atomizing head 6, a soft section 53 is fixedly installed on the fixed section 52, and the soft section 53 is connected to the mixer 3; the sleeve 4 includes a cylinder 41 and a mounting plate 42 fixed on the cylinder 41, the mounting plate 42 has an elongated groove 43; the fixed section 52 is rotatably connected to the elongated groove 43 of the mounting plate 42 through a rotating shaft 54; the end of the rotating shaft 54 ​​has a thread, and a locking nut 55 threaded onto the rotating shaft 54 ​​is locked to the mounting plate 42.

[0056] By adopting the above technical solution, the locking nut 55 can be unscrewed during use, and the rotating shaft 54 ​​can be slid along the long groove 43 to remove the entire mask 5 for replacement. The installation and disassembly are both relatively simple.

[0057] Furthermore, after the mask 5 is installed, its angle can be adjusted to accommodate the different angle requirements of operators or users.

[0058] Working principle: When in use, first connect the first cannula 12 to the oxygen source, adjust the oxygen flow rate through the control valve 15, and the oxygen enters the mixer 3 through the air guide tube 2 to carry out the medicine solution. It is then sprayed out through the nebulizer head 6, and the operator inhales the oxygen containing the medicine solution to complete the treatment process. During the process of injecting the medicine solution into the mixer 3, by pulling the piston rod 85, the injection tube 81 draws the medicine solution from the storage tank 7, and then pushes the piston rod 85 to inject the medicine solution into the mixer 3.
