Description

Technical Field

[0001] This utility model relates to the field of medical nebulization equipment technology, and in particular to an oxygenated nebulizer for pneumoconiosis. Background Technology

[0002] Pneumoconiosis is a systemic disease characterized by diffuse fibrosis of the lungs, caused by long-term inhalation and retention of industrial dust in the lungs. Patients often experience symptoms such as cough, sputum production, chest tightness, and difficulty breathing, and their lung ventilation and gas exchange functions gradually decline. Oxygenated nebulizers for pneumoconiosis are medical devices specifically designed for these patients. Their core function is to convert liquid medications into tiny droplets while simultaneously delivering oxygen, allowing the medication droplets to enter the patient's lungs along with the oxygen. This achieves precise drug delivery and alleviates the patient's hypoxia symptoms, making it an important tool for the daily treatment and adjunctive treatment during acute exacerbations of pneumoconiosis.

[0003] In the prior art, such as Chinese Patent Publication No. CN221713178U, an oxygen nebulizer inhaler is disclosed. It includes a base, an oxygen cylinder body on top of the base, a nebulizer on the outside of the oxygen cylinder body, an inhalation tube on the outside of the nebulizer, and a protective assembly on top of the base. The protective assembly includes a first protective ring, a second protective ring, a first connecting seat, a connecting rod, and a second connecting seat. The first protective ring is fixedly connected to the top of the base, and the second protective ring is fixedly connected to the outside of the oxygen cylinder body. The first connecting seat is fixedly connected to the outside of the second protective ring. The oxygen nebulizer inhaler provided by this utility model solves the problem that in some existing oxygen nebulizer inhalers, when the oxygen cylinder is placed on the ground, it may be bumped by passing people, causing fluctuations in the oxygen cylinder pressure and affecting its normal use.

[0004] Although the oxygen nebulizer in the above-mentioned technical solution uses a protective assembly consisting of a first and second protective ring to surround and protect the oxygen cylinder, thus preventing collisions and ensuring its stability, the following problems still exist for clinical use and the treatment needs of pneumoconiosis patients: First, the extended connecting rod, second connecting seat, and fixing strip in the protective assembly protrude from the outside of the base, increasing the overall footprint and lateral range of the device. In scenarios with high personnel flow, such as wards and treatment rooms, this can easily trip passing medical staff or patients, posing a safety hazard. Second, the use of fixed-size protective rings to limit the oxygen cylinder, without an adjustable fixing structure, only accommodates a single size of oxygen cylinder. When it is necessary to change to a different size oxygen cylinder, the protective assembly cannot effectively fix it, resulting in unstable placement of the oxygen cylinder and affecting the safety of the treatment process. Therefore, we propose a new type of oxygen nebulizer for pneumoconiosis to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology where the protective components, such as the extended connecting rod, the second connecting seat, and the fixing strip, are prone to snagging on people and the fixing structure is of a fixed size. Therefore, this invention proposes an oxygenated nebulizer for pneumoconiosis.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an oxygenated nebulizer for pneumoconiosis, comprising a support base, a fixed bracket fixedly connected to the top center of the support base, an oxygen cylinder disposed on the inner side of the fixed bracket, and a nebulizing component fixedly connected to the top of the oxygen cylinder.

[0007] The fixed bracket includes two connecting ring frames arranged vertically. A movable groove is opened in the middle of the connecting ring frame. A drive wheel is rotatably connected to both the left and right sides of the movable groove. A driven gear ring is meshed with the outer surfaces of the two drive wheels on the same side. Three push rods are rotatably connected in a ring array on the inner surface of the driven gear ring. A rotating arm is rotatably connected to the end of the push rod away from the driven gear ring. One end of the rotating arm is rotatably connected to the inner side of the connecting ring frame, and the other end of the rotating arm is rotatably connected to a pressure wheel.

[0008] Preferably, each of the four bottom corners of the support base is provided with a movable wheel, and each of the four top corners of the support base is fixedly connected with a drive motor. The output shaft of the drive motor is fixedly connected with a drive screw. The outer surface of the drive screw is threaded with a lifting slide plate. The top of the drive screw is fixedly connected with a limit baffle. The lower surface of the lifting slide plate away from the drive screw is fixedly connected with a sliding column. The bottom end of the sliding column extends through to the bottom of the support base and is fixedly connected with an anti-slip base plate.

[0009] Preferably, the bottom connecting ring frame is fixedly connected to the top center of the support base, and a column is fixedly connected to the left and right sides of the opposite faces of the two connecting ring frames. A connecting shaft is fixedly connected to the opposite faces of the two drive wheels on the same left and right sides, and the connecting shaft is rotatably connected to the column.

[0010] Preferably, drive motors are fixedly connected to the top left and right sides of the top connecting ring frame, and the output shaft of the drive motor passes through the interior of the top movable groove and is fixedly connected to the middle of the top drive wheel.

[0011] Preferably, an electric push rod is fixedly connected to the front side of the connecting ring frame, and the output end of the electric push rod extends through the interior of the movable groove and is fixedly connected to a positioning tooth.

[0012] Preferably, the push rod includes a connecting plate, which is movably connected to the inner surface of the driven gear ring, and a sliding plate is fixedly connected to the end of the connecting plate away from the driven gear ring.

[0013] Preferably, a connecting sleeve is slidably connected to the outer surface of the sliding plate, and the end of the connecting sleeve away from the sliding plate is movably connected to the outer surface of the rotating arm.

[0014] Preferably, a sliding pressure plate is fixedly connected to the end of the sliding plate away from the connecting plate, the sliding pressure plate is slidably connected to the inner surface of the connecting sleeve, and a buffer spring is fixedly connected to the side of the sliding pressure plate away from the sliding plate, the end of the buffer spring away from the sliding pressure plate is fixedly connected to the inner wall of the connecting sleeve.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. In this utility model, through the cooperation between the transmission motor, transmission screw, lifting slide plate, sliding column, and anti-slip base plate on the support base, this structure firstly solves the problems of the extended structure increasing the equipment's footprint and easily tripping passersby, thus eliminating safety hazards in personnel flow scenarios such as wards and treatment rooms; secondly, by adjusting the forward and reverse rotation of the transmission motor, the lifting height of the anti-slip base plate can be controlled. This not only increases the friction between the equipment and the ground by lowering the anti-slip base plate to prevent the device from slipping, but also allows for fine-tuning of the overall height of the support base according to the operating habits of medical staff or the treatment posture of patients, improving the flexibility and comfort of equipment use, and better meeting the operational needs of pneumoconiosis patients during long-term treatment.

[0017] 2. In this utility model, through the cooperation of the drive motor, drive wheel, driven gear ring, push rod, rotating arm, and clamping wheel on the fixed bracket, as well as the electric push rod, positioning teeth, and the internal buffer structure of the push rod, this structure has two main advantages. First, the adjustable clamping structure driven by the drive motor solves the problem that the existing technology can only fix a single type of oxygen cylinder and is unstable, ensuring the safety of oxygen cylinder placement during treatment. Second, the locking cooperation between the electric push rod and the positioning teeth prevents the driven gear ring from loosening due to external force or transmission gap, further improving the reliability of clamping and fixing. At the same time, the buffer spring inside the push rod absorbs the slight shaking of the oxygen cylinder or the instantaneous impact force during clamping through elastic deformation, which can not only prevent the outer wall of the oxygen cylinder from being damaged by rigid compression, but also reduce the vibration and noise of the equipment during operation, creating a more stable and quiet treatment environment for patients with pneumoconiosis.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution: it includes a support base 1, a fixed bracket 2 is fixedly connected to the top center of the support base 1, an oxygen cylinder 3 is arranged inside the fixed bracket 2, an atomizing component 4 is fixedly connected to the top of the oxygen cylinder 3, movable wheels 11 are arranged at the four corners of the bottom of the support base 1, a drive motor 12 is fixedly connected to the four corners of the top of the support base 1, a drive screw 13 is fixedly connected to the output shaft of the drive motor 12, a lifting slide plate 14 is threadedly connected to the outer surface of the drive screw 13, a limit baffle 15 is fixedly connected to the top of the drive screw 13, a sliding column 16 is fixedly connected to the lower surface of the lifting slide plate 14 away from the drive screw 13, and the bottom end of the sliding column 16 extends through to the bottom of the support base 1 and is fixedly connected to an anti-slip base plate 17;

[0026] The overall effect of Embodiment 1 is as follows: the moving wheels 11 can easily push the support base 1 to move the entire device, meeting the treatment needs of patients in different beds in the ward; when the device moves to the designated position, the drive motor 12 is started, and the output shaft of the drive motor 12 drives the drive screw 13 to rotate. Because the lifting plate 14 is threadedly engaged with the drive screw 13, and the sliding column 16 slides with the support base 1, the lifting plate 14 is restricted from rotating with the drive screw 13. The lifting plate 14 moves downward along the axis of the drive screw 13, driving the sliding column 16 to move downward synchronously, so that the anti-slip base plate 17 is in close contact with the ground. The anti-slip base plate 17 increases the friction with the ground and prevents the device from slipping; the limiting baffle 15 can prevent the lifting plate 14 from disengaging from the top of the drive screw 13, ensuring the stability of the structure; if it is necessary to adjust the height of the device to suit the operation of medical staff or the posture of patients, the lifting range of the sliding column 16 can be adjusted by controlling the forward and reverse rotation of the drive motor 12, thereby changing the overall height of the support base 1 and improving the flexibility of use.

[0027] Example 2: Figure 3 As shown, this utility model provides a technical solution: the fixed bracket 2 includes two vertically arranged connecting ring frames 21. A movable groove is formed in the middle of each connecting ring frame 21. Driving wheels 23 are rotatably connected to both the left and right sides of the movable groove. A driven gear ring 24 is meshed with the outer surfaces of the two driving wheels 23 on the same vertical side. Three push rods 25 are movably connected in a circular array to the inner surface of the driven gear ring 24. A rotating arm 26 is movably connected to the end of each push rod 25 away from the driven gear ring 24. One end of the rotating arm 26 is movably connected to the inner side of the connecting ring frame 21, and the other end of the rotating arm 26 is rotatably connected to a pressure wheel 27. The bottom... The connecting ring frame 21 is fixedly connected to the top center of the support base 1. A column is fixedly connected to the left and right sides of the opposite faces of the two connecting ring frames 21. A connecting shaft is fixedly connected to the opposite faces of the two drive wheels 23 on the same left and right sides. The connecting shaft is rotatably connected to the column. A drive motor 22 is fixedly connected to the left and right sides of the top of the connecting ring frame 21. The output shaft of the drive motor 22 passes through the interior of the top movable groove and is fixedly connected to the middle of the top drive wheel 23. An electric push rod 28 is fixedly connected to the front side of the connecting ring frame 21. The output end of the electric push rod 28 passes through the interior of the movable groove and is fixedly connected to a positioning tooth 29.

[0028] The overall effect of Embodiment 2 is as follows: the column supports and fixes the two connecting ring frames 21, and at the same time, it provides stable rotational support for the driving wheel 23 through the rotating engagement of the connecting shaft with the driving wheel 23; after the oxygen cylinder 3 is placed inside the two connecting ring frames 21, the drive motor 22 is started, and the output shaft of the drive motor 22 drives the top driving wheel 23 to rotate. The top driving wheel 23 drives the driven gear ring 24 to rotate around the circumference of the movable groove of the connecting ring frame 21 through meshing transmission. When the driven gear ring 24 rotates, it pulls or pushes the three push rods 25 of the annular array, and the push rods 25 drive the rotating arm. Rotating arm 26 rotates around the hinge point on the inner side of the connecting ring frame 21, causing the clamping wheel 27 at the end of rotating arm 26 to move closer to and press against the outer wall of oxygen cylinder 3, thus fixing oxygen cylinder 3. After the clamping wheel 27 is in close contact with oxygen cylinder 3, the electric push rod 28 is activated. The output end of the electric push rod 28 pushes the positioning tooth 29 to engage in the tooth gap of the driven tooth ring 24, restricting the reverse rotation of the driven tooth ring 24 and preventing the rotating arm 26 from loosening due to external force or transmission clearance, further improving the fixing stability of oxygen cylinder 3. Moreover, the three clamping wheels 27 act synchronously to ensure that oxygen cylinder 3 is subjected to uniform force and prevent it from shifting.

[0029] Example 3: As Figure 4 As shown, this utility model provides a technical solution: the push rod 25 includes a connecting plate 251, the connecting plate 251 is movably connected to the inner surface of the driven gear ring 24, a sliding plate 252 is fixedly connected to one end of the connecting plate 251 away from the driven gear ring 24, a connecting sleeve 253 is slidably connected to the outer surface of the sliding plate 252, one end of the connecting sleeve 253 away from the sliding plate 252 is movably connected to the outer surface of the rotating arm 26, a sliding pressure plate 254 is fixedly connected to one end of the sliding plate 252 away from the connecting plate 251, the sliding pressure plate 254 is slidably connected to the inner surface of the connecting sleeve 253, a buffer spring 255 is fixedly connected to one side of the sliding pressure plate 254 away from the sliding plate 252, and one end of the buffer spring 255 away from the sliding pressure plate 254 is fixedly connected to the inner wall of the connecting sleeve 253;

[0030] The overall effect achieved by embodiment 3 is as follows: the connecting plate 251 realizes the movable connection between the push rod 25 and the driven gear ring 24, ensuring that the driven gear ring 24 can drive the push rod 25 to move flexibly when it rotates; when the push rod 25 pushes the rotating arm 26 to make the clamping wheel 27 press against the oxygen cylinder 3, if there is a slight difference in the outer diameter of the oxygen cylinder 3 or it is subjected to a slight external impact, the connecting sleeve 253 will slide along the sliding plate 252, causing the sliding pressure plate 254 to squeeze the buffer spring 255. The buffer spring 255 absorbs the impact force through elastic deformation, avoiding the clamping wheel 27 from causing rigid compression on the oxygen cylinder 3 and preventing damage to the outer wall of the oxygen cylinder 3; at the same time, the rebound force of the buffer spring 255 can keep the clamping wheel 27 in contact with the outer wall of the oxygen cylinder 3, ensuring that the fixing effect is not weakened and improving the protection and adaptability of the equipment to the oxygen cylinder 3.

[0031] The working principle of the entire device is as follows: Before use, the device is pushed to the treatment position of the pneumoconiosis patient by the moving wheels 11 at the bottom of the support base 1. The drive motor 12 is started, which drives the drive screw 13 to rotate, causing the lifting plate 14 to move the sliding column 16 down. The anti-slip base plate 17 contacts the ground to fix the device. If the height needs to be adjusted, the lifting range of the sliding column 16 can be adjusted by continuing to control the drive motor 12. Then, the oxygen cylinder 3 is placed inside the two connecting ring frames 21 of the fixed bracket 2. The drive motor 22 is started, which drives the top drive wheel 23 to rotate. The drive wheel 23 meshes with the driven gear ring 24, which drives the rotating arm 26 to rotate through the push rod 25, so that the pressure wheel 27 presses the oxygen cylinder. The outer wall of the oxygen cylinder 3 is then closed. Next, the electric push rod 28 is activated, and the positioning tooth 29 engages with the teeth of the driven tooth ring 24 to complete the locking. At this time, the outlet of the oxygen cylinder 3 is connected to the nebulizer 4. The nebulizer 4 converts the therapeutic drug into droplets, and the oxygen carrying the droplets is delivered to the patient's lungs through the mask to achieve drug administration and oxygen supplementation. During the treatment, the buffer spring 255 inside the push rod 25 can absorb the slight shaking of the oxygen cylinder 3 to ensure stable operation of the equipment. After the treatment, the oxygen cylinder 3 and the nebulizer 4 are closed first, then the electric push rod 28 is activated to retract the positioning tooth 29, the drive motor 22 is activated in reverse to disengage the pressure wheel 27 from the oxygen cylinder 3, and finally the transmission motor 12 is activated in reverse to lift the anti-slip base plate 17, which can then push the equipment away from the treatment position.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
