Description

Technical Field

[0001] This invention relates to the field of nebulized medical equipment technology, specifically to a nebulizer mask and nebulizer for use by supine patients. Background Technology

[0002] Currently, commonly used nebulizer masks in clinical practice typically consist of a mask body, an air inlet, and an exhaust valve. Their initial design was primarily for patients who can sit up or be semi-recumbent, relying on gravity to help expel condensed moisture from the mask. When these masks are used on supine patients (such as those with severe illnesses, post-operative patients, or patients with spinal injuries), the air intake, exhaust, and condensation management all occur on the same horizontal plane, creating an inherent contradiction between the working principle and the intended use scenario. Therefore, there is a need to develop and design nebulizer masks specifically for supine patients.

[0003] The patent publication CN118987416B, entitled "An Airflow Nebulizer Applicable to Supine Positions," describes a nebulizer comprising a cup body, a nebulizer core, a mask, a connecting tube, and a fixing strap. The nebulizer core has a cap at its top, and the bottom of the cup body protrudes inward to form an air inlet. An air inlet tube connects to the bottom of the air inlet. The nebulizer core includes an upper connecting rod and a lower nebulizer rod, which are rotatably connected. A connecting cap that can be fastened to the air inlet is located at the bottom of the nebulizer rod. An outlet is opened at the top of the connecting cap, and a medication absorption groove communicating with the outlet is opened on the inner wall of the connecting cap. A flow divider is located above the outlet, and guide plates perpendicular to it are located on both sides of the flow divider. The two ends of the guide plates protrude from the sides of the flow divider. A mist outlet channel is formed between the connecting rod and the cup body, solving the problem of limited use of existing nebulizers in supine positions.

[0004] Neither the aforementioned patents nor existing publicly available technologies have been able to solve the problem of condensation that occurs when the patient's exhaled warm, moist air mixes with the low-temperature medication mist inside the mask. This condensation cannot be effectively channeled away by gravity and easily accumulates at the point of contact between the mask and the patient's face. This not only wastes medication and causes facial discomfort due to moisture, but also poses a serious safety risk of aspiration of the accumulated fluid into the airway. Secondly, the residual waste gas inside the mask (including exhaled carbon dioxide and excess medication mist) is difficult to be naturally replaced by fresh airflow, causing the patient to repeatedly inhale moist, low-oxygen waste gas, resulting in poor comfort and potentially affecting treatment efficacy. Furthermore, it requires medical staff to frequently wipe and tilt the mask, increasing the nursing burden and often having limited effectiveness, failing to fundamentally solve the problems caused by the supine position. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a nebulizer mask and nebulizer for supine patients, solving the problem that traditional nebulizer masks and nebulizers are unsuitable for supine patients or have unsatisfactory effects.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A nebulizer mask for use by a supine patient includes: The mask body has ear loop holes on its side; An exhaust assembly is fixed to the inner wall of the mask body. The exhaust assembly has an air collection part that opens toward the inside of the mask and an exhaust pipe that communicates with the inside of the air collection part. The outlet end of the exhaust pipe extends to the outside of the mask body or is connected to a first interface that communicates the inside and outside of the mask body. An air intake assembly is suspended inside the mask body, with its outlet facing the patient's mouth and nose area. The air intake assembly has an air intake channel, the inlet of which extends to the outside of the mask body or is connected to an external interface that connects the inside and outside of the mask body. An exhaled gas overflow channel is formed between the outer side of the air intake component and the inner wall of the mask body.

[0007] Preferably, the inner wall of the mask body is provided with a top cavity, and the air collection part of the exhaust assembly is fixedly disposed inside the top cavity.

[0008] Preferably, the side of the mask body is provided with an air tube section, and the end part of the air tube section is connected to an external interface, a first interface, and a second interface; A valve or a damping hollow tube is installed at one end of the second interface.

[0009] Preferably, the damping hollow tube includes: a protective tube, an inner tube body, and inner protrusions. The inner tube body is fixedly disposed inside the protective tube, and a plurality of inner protrusions are disposed inside the inner tube body and spaced apart along the axial direction of the inner tube body.

[0010] Preferably, the air intake assembly has a clearance notch corresponding to the shape of the human nose bridge.

[0011] Preferably, the inner wall of the mask body is integrally provided with a first annular collecting part, and the cross-sectional shape of the first collecting part is "C".

[0012] Preferably, the bottom plate of the gas collecting section has grid holes.

[0013] A nebulizer for use by a supine patient includes: Atomizer mask, which is the atomizer mask described above; The atomizing cup has its outlet connected to the air inlet assembly of the atomizer mask via a first pipe, and the air inlet of the atomizing cup is connected to an air inlet pipe. A venturi, the venturi having a drive gas inlet, a suction gas inlet, and a mixed gas outlet; The driving air inlet is connected to the air inlet pipe upstream of the air inlet of the atomizing cup via a branch pipe, and the suction inlet is connected to the exhaust assembly of the atomizer mask via a second pipe.

[0014] Preferably, the venturi component includes: A first tube, a neck, and a second tube are coaxially arranged and integrally formed, wherein the neck constitutes a Venturi throat and its diameter is smaller than that of the first tube and the second tube. The first tube is closed at one end, and the driving air inlet is provided on its tube wall or end. The suction inlet is provided on the side wall of the neck. A sealing cap is installed at the end of the second tube section, and at least one side hole is opened on the side wall of the second tube section. Several metal pillars are fixedly connected to the side of the sealing cap facing the inside of the second tube section.

[0015] Preferably, the interior of the second tube is provided with a sponge layer.

[0016] This invention provides a nebulizer mask and nebulizer for use by supine patients. It has the following beneficial effects: This invention, through the internal design of an exhaust component and an intake component within the mask body, with the intake component suspended inside the mask body and not in contact with the patient's skin, effectively confines the atomized gas containing medication to a small area, allowing for efficient inhalation of the medication. Furthermore, a gap is formed between the bottom of the intake component and the patient's skin, allowing exhaled gas to overflow through this gap (as the patient exhales, atomized gas containing medication is continuously introduced, increasing the gas volume within the confined area of ​​the intake component, causing natural overflow). The gas then flows through the exhaled gas overflow channel formed between the outer side of the intake component and the inner wall of the mask body to the exhaust component, where it is discharged. Compared to traditional masks, the patient's exhaled warm and humid gas is quickly expelled, resulting in less condensation on the inner wall of the mask body. This eliminates the need for frequent wiping and tilting of the mask by medical staff, and provides a better user experience, making it particularly suitable for supine patients (such as those with severe illness, post-operative conditions, or spinal injuries).

[0017] This invention designs a second interface, one end of which is equipped with a valve or a damping hollow tube, to maintain a stable air pressure inside the mask body (slightly higher than the positive pressure of the environment), ensuring a good user experience for patients.

[0018] This invention designs a nebulizer that uses a venturi component to draw in the patient's exhaled gas from the exhaust assembly. When in use, it does not require an additional pump source and can start working synchronously with the nebulizer cup, ensuring that the exhaust assembly and the air intake assembly work in sync.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0022] like Figures 1-3As shown, this embodiment of the invention provides a nebulizer mask for supine patients, which belongs to the nebulizer industry of medical engineering. It is mainly used for nebulization treatment of supine patients (such as critically ill, postoperative, and spinal injury patients). Of course, this nebulizer mask realizes all the functions of a general mask and can also be used in general scenarios; it includes a mask body 1, an exhaust component 11, and an air intake component 6.

[0023] The mask body 1 is designed based on the contours of the human face and is used to cover the patient's mouth and nose. Ear loop holes 3 are provided on the side of the mask body 1. Two sets of ear loop holes 3 are symmetrically arranged about the central axis of the mask body 1 for attaching ear loops. The ear loops can be worn on the patient's ears or head, ensuring a stable fit of the mask body 1 on the patient's face. The exhaust assembly 11 is fixed to the inner wall of the mask body 1. Figure 1 As shown, the exhaust assembly 11 can be fixed to the inner top of the mask body 1. The exhaust assembly 11 has an air collecting part that opens towards the inside of the mask and an exhaust pipe 11b that communicates with the inside of the air collecting part. The gas exhaled by the patient inside the mask body 1 is collected by the air collecting part and then drawn out from the exhaust pipe 11b. The outlet end of the exhaust pipe 11b extends to the outside of the mask body 1 or is connected to the first interface 9 that connects the inside and outside of the mask body 1. Using the first interface 9 as a transition method makes the structure simpler and easier to mold and manufacture the mask body 1. The air intake assembly 6 is suspended inside the mask body 1. It can be directly connected to the air intake assembly 6, or it can be based on the air intake channel 6b of the air intake assembly 6 to keep the main body of the air intake assembly 6 relative to the mask body 1. The mask body 1 is fixedly connected. After the mask body 1 is worn on the patient's face, a gap is formed between the outlet of the air intake component 6 and the patient's face, and an exhaled gas overflow channel is formed between the outer side of the air intake component 6 and the inner wall of the mask body 1. The outlet of the air intake component 6 faces the patient's mouth and nose area, which can form a small area above the patient's mouth and nose area, confining the atomized gas containing the drug solution within this small area. The patient can efficiently inhale the atomized drug solution. The air intake component 6 has an air intake channel 6b. The inlet of the air intake channel 6b extends to the outside of the mask body 1 or is connected to the external interface 7 that connects the inside and outside of the mask body 1. Using the external interface 7 as a transition method makes the structure simpler and easier to mold and manufacture the mask body 1.

[0024] It is understood that the exhaust assembly 11 is used to expel the exhaled gas inside the mask body 1, and a suction pump or other structure that can realize suction function can be installed externally (such as the Venturi component used in Embodiment 2). The air intake assembly 6 is used to guide the external (medication-containing) atomized gas into the mask body 1. Its corresponding air intake channel 6b end or the end of the external interface 7 as a transition is connected to the air outlet pipe of the atomizing cup. In use, the (medication-containing) atomized gas enters through the external interface 7 and the air intake channel 6b, and is concentrated in a small area corresponding to the patient's nose-picking area under the restriction of the air intake assembly 6 body, so that the patient can efficiently inhale the atomized medication. At the same time, the patient's exhaled gas can come into contact with the patient's skin from the bottom of the air intake assembly 6. The gas overflows through the gap formed between the air intake component and the mask body 1 (as the patient exhales, the nebulized gas containing the medication is continuously introduced, increasing the amount of gas within the range limited by the air intake component, and the gas naturally overflows. When the patient inhales, the nebulized gas (containing the medication) entering through the air intake component 6 is inhaled). Then, the exhaled gas flows through the exhalation overflow channel formed between the outer side of the air intake component 6 and the inner wall of the mask body 1 to the exhaust component 11 and is discharged from the exhaust component 11. In this periodic cycle, the patient's exhaled gas can be discharged, preventing the formation of excessive condensation in the mask body 1. This eliminates the need for medical staff to frequently wipe or tilt the mask, and provides a better user experience for patients, especially suitable for use by supine patients (such as critically ill, postoperative, or spinal injury patients).

[0025] In one embodiment, the inner wall of the mask body 1 is provided with a top cavity 5, and the air collection part of the exhaust assembly 11 is fixedly disposed inside the top cavity 5.

[0026] The top cavity 5 is integrally formed on the inner top of the mask body 1 and is used to install the exhaust assembly 11. For example, the inner cavity design of the top cavity 5 is matched with the outer side of the exhaust assembly 11, and the exhaust assembly 11 is tightly snapped into the inside of the top cavity 5. This structural design makes it easy for the mask body 1 and the exhaust assembly 11 to be manufactured independently and then assembled for installation and use.

[0027] In the above structure, the mask body 1 needs to be formed with a first interface 9, and the exhaust pipe 11b of the exhaust assembly 11 is ultrasonically welded to the end of the first interface 9.

[0028] In one embodiment, an air tube section 4 is provided on the side of the mask body 1. The air tube section 4 and the mask body 1 are integrally molded. The air tube section 4 is basically parallel to the top of the mask body 1, which facilitates the arrangement of externally connected air tubes. An external interface 7, a first interface 9, and a second interface 10 are connected to the end face 8 of the air tube section 4.

[0029] The external interface 7 serves as an adapter for the air intake assembly 6, and the first interface 9 serves as an adapter for the exhaust assembly 11; one end of the second interface 10 is equipped with a valve or a damping hollow tube 17 to maintain stable air pressure inside the mask body 1 (e.g., maintain a positive pressure slightly higher than the environment) to ensure a good user experience.

[0030] For example, the valve is selected as an adjustable valve to adjust the cross-sectional area of ​​the second interface 10 that connects to the outside. There is resistance in the process of the gas inside the mask body 1 flowing to the outside, so that the air pressure inside the mask body 1 is kept at a positive pressure slightly higher than the environment.

[0031] For example, using a damping hollow tube 17, gas flowing outward from the second interface 10 enters the damping hollow tube 17. There is resistance to the flow of gas in the damping hollow tube 17, and the resistance increases with the length of the damping hollow tube 17. The user can cut the damping hollow tube 17 according to actual needs, leaving a suitable length of damping hollow tube 17 to ensure that the air pressure inside the mask body 1 is kept slightly higher than the positive pressure of the environment.

[0032] In one embodiment, such as Figure 7 As shown, the damping hollow tube 17 includes: a protective tube 173, an inner tube body 171, and inner protrusions 172. The inner tube body 171 is fixedly disposed inside the protective tube 173, and a plurality of inner protrusions 172 are disposed inside the inner tube body 171 and spaced apart along the axial direction of the inner tube body 171.

[0033] It is understandable that the airflow flows inside the inner tube 171 and passes through the narrow channel formed by the inner protrusions 172. This narrow channel has an obstructive effect on the airflow. When passing through multiple inner protrusions 172, it will have a certain obstructive effect on the gas. When in use, the damping hollow tube 17 is cut off at an appropriate position, leaving an appropriate length of damping hollow tube 17 (corresponding to an appropriate number of inner protrusions 172).

[0034] In one embodiment, the air intake assembly 6 is provided with a clearance notch 6a corresponding to the shape of the human nose bridge. The clearance notch 6a corresponds to the human nose bridge, so that a gap is formed between the bottom of the clearance notch 6a and the nose bridge, allowing airflow to flow outward (outside the air intake assembly 6).

[0035] In one embodiment, the inner wall of the mask body 1 is integrally provided with a first annular collection part 2, the cross-sectional shape of the first collection part 2 is "C" shaped, and a tank is formed between the first collection part 2 and the inner wall of the mask body 1 to retain some liquid.

[0036] Although the design of the exhaust assembly 11 and the intake assembly 6 allows most of the patient's exhaled air to be directly discharged, some of the patient's exhaled air may still come into contact with the mask body 1 and produce liquid. This part of the liquid can be temporarily stored in the groove formed between the first collection part 2 and the inner wall of the mask body 1.

[0037] In one embodiment, the bottom plate 1101 of the gas collecting section has grid holes 11a, through which gas flows upward and then enters the interior of the gas collecting section. Example

[0038] like Figures 1-7 As shown, this embodiment of the invention provides a nebulizer for supine patients, which belongs to the nebulizer industry of medical engineering. It is mainly used for nebulization treatment of supine patients (such as critically ill, postoperative, and spinal injury patients). Of course, this nebulizer realizes all the functions of a general nebulizer and can also be used in general scenarios. It includes: nebulizer mask, nebulizer cup 13, and venturi component 16.

[0039] In this embodiment, the nebulizer mask is the same as that in Embodiment 1. The outlet of the nebulizer cup 13 is connected to the air inlet assembly 6 of the nebulizer mask via the first pipe 12, for delivering nebulized gas containing medication to the nebulizer mask through the first pipe 12. The air inlet of the nebulizer cup 13 is connected to an air inlet pipe 14, the other end of which is connected to a high-oxygen-content gas supply port / other gas supply equipment in the hospital, for supplying gas to the nebulizer cup 13 through the air inlet pipe 14. The venturi component 16 has a driving function. The device includes a driving air inlet 163, a suction air inlet 169, and a mixed air outlet. The driving air inlet 163 is connected to the air inlet pipe 14 upstream of the air inlet of the atomizing cup 13 via a branch pipe 15. The suction air inlet 169 is connected to the exhaust assembly 11 of the atomizer mask via a second pipe 18. The branch pipe 15 introduces some gas from the air inlet pipe 14, which passes through the interior of the venturi 16, creating a negative pressure at the suction air inlet 169, and drawing the gas from the exhaust assembly 11 along the second pipe 18.

[0040] The connection between the bronchus 15 and the inlet pipe 14 can be designed with a three-way structure, and a flow regulating valve can be installed at the bronchus 15 to distribute the airflow into the bronchus 15 and the inlet pipe 14 based on user settings.

[0041] The connection between the bronchus 15 and the inlet pipe 14 can be a one-piece structure. By designing the pipe diameters of the bronchus 15 and the inlet pipe 14, the airflow entering the bronchus 15 and the inlet pipe 14 can be distributed. For example, the airflow ratio between the bronchus 15 and the inlet pipe 14 can be 1:5.

[0042] Understandably, the nebulizer is designed to use a venturi component 16 to draw in the patient's exhaled gas from the exhaust assembly 11. When in use, no additional pump source is required, and it can start working synchronously with the nebulizer cup 13, ensuring that the exhaust assembly 11 and the air intake assembly 6 work synchronously.

[0043] In one embodiment, such as Figure 6 As shown, the venturi component 16 includes a first tube portion 161, a neck portion 162, and a second tube portion 164 that are coaxially arranged and integrally formed. The neck portion 162 constitutes the venturi throat, and its diameter is smaller than that of the first tube portion 161 and the second tube portion 164. The diameter of the first tube 161 is smaller than that of the second tube 164, and the connection between the first tube 161, the second tube 164 and the neck 162 is a tapered transition structure. The end of the first tube 161 is closed, and a driving air inlet 163 is provided on the tube wall or end of the first tube 161. For example, a driving air inlet 163 is provided at the center of the end of the first tube 161. The driving air inlet 163 is fixedly connected to one end of the bronchus 15. An air extraction inlet 169 is provided on the side wall of the neck 162. The air extraction inlet 169 is fixedly connected to one end of the second pipe 18. A sealing cap 167 is installed at the end of the second tube 164. At least one side hole 165 is opened on the side wall of the second tube 164. Several metal pillars 168 are fixedly connected to the side of the sealing cap 167 facing the inside of the second tube 164.

[0044] Understandably, when the bronchus 15 introduces a high-speed airflow through the first tube section 161 and the neck 162, the cross-sectional area through which the airflow passes is small when it enters the neck 162, the airflow velocity increases, and a negative pressure is formed around it. Part of the airflow is drawn in from the suction inlet 169, and the mixed airflow enters the second tube section 164 together. This part of the gas comes into contact with several metal columns 168. The surfaces of the several metal columns 168 are smooth and the temperature is low, which is conducive to the liquefaction of the moisture carried in the gas. The mixed gas is discharged through the side hole 165.

[0045] In one embodiment, a sponge layer 166 is provided inside the second tube 164. The sponge layer 166 has the function of absorbing liquid. Liquid generated on the surface of the metal column 168 flows to the sponge layer 166 and is absorbed.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
