Description

Technical Field

[0001] This application relates to the field of medical nebulizer technology, and more particularly to a nebulizer device for treating respiratory patients. Background Technology

[0002] Nebulized inhalation is a treatment method that involves atomizing medication and delivering it through the mouth and nose to the patient's pharynx, bronchi, and lungs. Compared to traditional oral medication, nebulized inhalation allows the medication to act directly on the affected area, exerting its effects and achieving therapeutic goals at the fastest speed. As a result, it is widely used in the treatment of various respiratory diseases.

[0003] Among them, the main tool used for nebulized inhalation therapy for patients is the medical nebulizer, which is designed based on the principles of fluid mechanics (high flow rate, low pressure, and low flow rate, high pressure). It uses a high-speed flow of oxygen to draw out and atomize the medication, and then delivers it to a mask or mouthpiece through a tubing to treat the patient's lesion. However, in the process of using existing medical nebulizers, as the amount of medication at the bottom of the shell decreases and the relative cavity volume increases, the remaining medication becomes more difficult to draw out and atomize, leading to medication waste. At the same time, because the amount of medication added is relatively small, some remains at the bottom of the medical nebulizer shell, resulting in a reduced amount delivered to the patient's lesion, which greatly affects its therapeutic effect on the lesion.

[0004] Therefore, there is an urgent need for a medical nebulizer to address the shortcomings of existing medical nebulizers in practical use. Summary of the Invention

[0005] This application proposes a nebulizer for treating respiratory patients, which effectively extracts and atomizes the medication in the medical nebulizer without wasting any medication. Simultaneously, it ensures that the entire amount of medication is atomized and delivered to the patient's affected area, resulting in better treatment efficacy. This addresses the problem in existing medical nebulizers where, as the medication at the bottom of the housing decreases and the relative cavity volume increases, the remaining medication becomes increasingly difficult to extract and atomize, leading to medication waste. Furthermore, because the amount of medication added is relatively small, some remains at the bottom of the nebulizer housing, reducing the amount delivered to the patient's affected area and resulting in poorer treatment efficacy.

[0006] To achieve the above objectives, this application adopts the following technical solution: a nebulizer for treating respiratory patients, comprising an outer shell for containing a drug solution, a flow tube communicating with its inner cavity on the top of one side of the outer surface of the outer shell, two sets of symmetrically arranged L-shaped grooves on the top of the outer shell, and an inner plug movably sleeved in the inner cavity of the outer shell, which is secured in the inner cavity of the outer shell by the L-shaped grooves, a conical body at the bottom of the inner cavity of the outer shell, and a straight through hole with its bottom end communicating with the bottom of the outer shell inside the conical body. The top of the hole connects to the top of the cone, and the top of the cone has a first connecting hole inside; the inner plug includes a piston that is movably fitted into the inner cavity of the outer shell, the bottom of the piston has a conical groove that matches the cone, and a drainage groove that extends through to the upper and lower ends of the conical groove is formed on the inner wall of the conical groove; the top of the piston is axially movably engaged with a connecting rod, and an end cap that engages with an L-shaped groove on the outer shell is radially movably fitted at the middle of the outer surface of the connecting rod; a first spring is movably fitted at the bottom of the outer surface of the connecting rod and between the end cap and the piston.

[0007] Furthermore, a guide rod is fixedly sleeved on the top of the piston cavity, and a sealing plate with its bottom end in contact with the bottom of the piston cavity is movably sleeved on the bottom of the guide rod. A second spring is movably sleeved on the outer surface of the guide rod between the piston and the sealing plate. A second connecting hole is opened inside the bottom end of the sealing plate, which connects to its bottom.

[0008] Furthermore, a sealing ring is movably fitted into the gap formed between the conical body and the inner wall of the outer shell, and the sealing ring divides the gap into upper and lower layers. The upper layer of the gap is used to contain the liquid medicine, while the lower layer of the gap is connected to the through hole through a diversion hole opened inside the conical body.

[0009] Furthermore, the first connecting hole is designed with a broken line structure, and the upper half of the broken line is parallel to the drainage groove at the corresponding position.

[0010] Furthermore, the second spring adopts a constant pressure elastic structure, and the downward pressure it applies to the sealing plate is less than the pressure of the oxygen flow flowing in the through hole.

[0011] Furthermore, an adjustment hole with a fan-shaped structure that runs through both the upper and lower ends is provided inside one side of the end cap, and a baffle that can rotate along the central axis of the inner plug body is movably sleeved inside the end cap to adjust the size of the adjustment hole opening.

[0012] Furthermore, the outer surface of the piston is provided with a groove in an annular structure, and a sealing ring is fixedly fitted inside the groove, thereby effectively increasing the sealing between the piston and the inner wall of the outer casing.

[0013] This invention application has the following technical effects:

[0014] This application provides a nebulizer for treating respiratory patients. Under the action of the inner plug and its structure, the liquid medication located in the upper layer of the gap can be sealed first. Then, a portion of the oxygen pressure is used to force the sealing ring to move upward and squeeze the liquid medication in the upper layer of the gap. This allows all the liquid medication in the medical nebulizer to be completely drawn out and nebulized, preventing waste due to residue. At the same time, it ensures that all the liquid medication is nebulized and delivered to the patient's lesion, thereby effectively improving the treatment effect on the patient's lesion.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] like Figures 1-2As shown, a nebulizer for treating respiratory patients includes an outer shell 1 for containing medication. A flow tube 3, connected to its inner cavity, is located on the top of one side of the outer surface of the outer shell 1. One end of the flow tube 3 can be engaged with a face mask or mouthpiece to deliver the nebulized medication to the patient's affected area through the mouth and nose. Two sets of symmetrically arranged L-shaped grooves 2 are located at the top of the outer shell 1. An inner plug 4 is movably fitted into the inner cavity of the outer shell 1 and secured therein by the L-shaped grooves 2. Figure 3 As shown, a cone-shaped body 7 is provided at the bottom of the inner cavity of the outer shell 1. A gap for containing liquid medicine is left between the cone-shaped body 7 and the outer shell 1. A straight through hole 8 is opened inside the cone-shaped body 7, with its bottom end connected to the bottom of the outer shell 1. It is connected to an external pumping system through a hose so that high-speed flowing oxygen can be delivered to the inner cavity of the outer shell 1 through the straight through hole 8 on the cone-shaped body 7. The top end of the straight through hole 8 is connected to the top of the cone-shaped body 7. Three sets of first connecting holes 9 arranged in a ring array are opened inside the top end of the cone-shaped body 7.

[0025] like Figure 4 As shown, the inner plug 4 includes a piston 12 that is movably fitted into the inner cavity of the outer shell 1. The bottom of the piston 12 is provided with a conical groove 20 that cooperates with the conical body 7, and a drainage groove 21 that extends through to the upper and lower ends of the conical groove 20 is provided on the inner wall of the conical groove 20. When there is a high-speed oxygen flow in the through hole 8, the liquid medicine located at the bottom of the inner cavity of the outer shell 1 can be drawn out through the drainage groove 21 under the principle of fluid dynamics.

[0026] The piston 12 is axially and movably engaged with a connecting rod 13, and an end cap 14 is radially and movably sleeved on the middle of the outer surface of the connecting rod 13, which engages with the L-shaped groove 2 on the outer shell 1. The end cap 14 has two sets of symmetrically arranged protrusions at its top to facilitate rotation. A first spring 15 is movably sleeved on the bottom of the outer surface of the connecting rod 13, between the end cap 14 and the piston 12. Thus, under the action of the first spring 15, when the end cap 14 is engaged with the L-shaped groove 2, it can always apply downward pressure to the piston 12, and make the conical groove 20 fit tightly against the outer surface of the conical body 7.

[0027] like Figure 3 As shown, in this technical solution, a guide rod 16 is fixedly sleeved on the top of the inner cavity of the piston 12, and a sealing plate 17 with its bottom end in contact with the bottom of the inner cavity of the piston 12 is movably sleeved on the bottom of the guide rod 16 to prevent leakage of the medicine liquid during the movement of the medical nebulizer in the initial state. A second spring 18 is movably sleeved on the outer surface of the guide rod 16 between the piston 12 and the sealing plate 17. A second connecting hole 19 is opened inside the bottom end of the sealing plate 17, which communicates with its bottom.

[0028] In the initial state, under the elastic force of the second spring 18, the sealing plate 17 always has downward pressure to block the drainage groove 21. At the same time, the second connecting hole 19 and the first connecting hole 9 on the cone 7 are offset from each other.

[0029] When oxygen flows through the through hole 8, the sealing plate 17 is forced to move upward and compress the guide rod 16, so that the second connecting hole 19 and the first connecting hole 9 are connected to each other, and the liquid medicine located at the bottom of the inner cavity of the outer shell 1 is drawn out and atomized through the drainage groove 21.

[0030] like Figure 3 As shown, in this technical solution, a sealing ring 10 is movably fitted into the gap formed between the conical body 7 and the inner wall of the outer shell 1. The sealing ring 10 divides the gap into upper and lower layers. The upper layer of the gap is used to contain the liquid medicine, while the lower layer of the gap is connected to the through hole 8 through the diversion hole 11 opened inside the conical body 7. This allows a portion of the oxygen flowing through the through hole 8 to enter the lower layer of the gap through the diversion hole 11, forcing the sealing ring 10 to move upward and squeeze the liquid medicine located in the upper layer of the gap. This ensures that the liquid medicine can be completely drawn out and atomized, and that there will be no excessive residue at the bottom of the inner cavity of the outer shell 1.

[0031] like Figure 2 As shown, in this technical solution, the first connecting hole 9 is designed as a broken line structure, and the upper half of its broken line is parallel to the corresponding drainage groove 21. Therefore, when the liquid medicine is drawn out according to the principle of fluid mechanics, it will not cause excessive turbulence impact, so that it can be atomized evenly.

[0032] In this technical solution, the second spring 18 adopts a constant pressure elastic structure, and the downward pressure it applies to the sealing plate 17 is less than the oxygen flow pressure flowing in the through hole 8. Thus, when oxygen flows through the through hole 8, a portion of the oxygen can first be ensured to enter the lower layer of the gap through the diversion hole 11, forcing the sealing ring 10 to move upward and squeeze the liquid medicine located on the upper layer of the gap. Then, the sealing plate 17 is forced to move upward and compress the second spring 18 to connect the first connecting hole 9 and the second connecting hole 19. Under the action of high-speed oxygen flow, the liquid medicine located on the upper layer of the gap is drawn out and atomized through the drainage groove 21.

[0033] like Figure 5 As shown, in this technical solution, an adjustment hole 5 with a fan-shaped structure that runs through both the upper and lower ends is provided inside one side of the end cap 14, and a baffle 6 that can rotate along the central axis of the inner plug 4 is movably sleeved inside the end cap 14 to adjust the size of the opening of the adjustment hole 5. In this way, the oxygen flow pressure in the inner cavity of the outer shell 1 can be adjusted by adjusting the size of the opening of the adjustment hole 5, thereby achieving the purpose of adjusting the atomization speed of the liquid medicine.

[0034] In this technical solution, the outer surface of the piston 12 is provided with a groove in an annular structure, and a sealing ring made of rubber is fixedly sleeved inside the groove, thereby effectively increasing the sealing between the piston 12 and the inner wall of the outer shell 1, and preventing leakage of the liquid medicine located in the upper layer of the gap during the upward movement of the compression sealing ring 10.

[0035] When using this medical nebulizer, first rotate the end cap 14 and remove the inner plug 4 from the inner cavity of the outer shell 1. Then, put the prepared medicine solution into the inner cavity along the inner wall of the outer shell 1. After that, put the inner plug 4 back into the inner cavity of the outer shell 1 and use the end cap 14 to snap it into the L-shaped groove 2 of the outer shell 1. At the same time, connect the bottom of the outer shell 1 to the pumping system through the tubing, and attach a mask or mouthpiece to the flow tube 3 to connect it to the patient's face.

[0036] Then, the pumping system is activated, generating a high-speed oxygen flow that enters the inner cavity of the outer casing 1 through the hose and through-hole 8. Part of the oxygen in the through-hole 8 enters the lower layer of the gap through the diversion hole 11, forcing the sealing ring 10 to move upward and squeeze the medicine in the upper layer of the gap. Most of the oxygen applies upward pressure to the sealing plate 17 through the through-hole 8, forcing it to move upward and compress the second spring 18, causing the first connecting hole 9 and the second connecting hole 19 to connect with each other, and the channel of the drainage groove 21 is opened. Then, under the principle of fluid mechanics and the upward squeezing action of the sealing ring 10, the medicine in the upper layer of the gap is drawn out through the drainage groove 21 and atomized under the action of the high-speed oxygen flow. The atomized medicine then enters the patient's lesion through the mask or mouthpiece on the flow tube 3 to achieve the therapeutic effect.
