Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomization administration device, in particular to a handheld medical atomization administration device. BACKGROUND

[0002] The medical atomization administration device is mainly used for treating various upper and lower respiratory system diseases, such as cold, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases occurring in trachea, bronchus, alveolus and chest cavity.

[0003] In order to improve the convenience of the atomization administration device, most of the atomizers on the market have the characteristics of small size and portability, which are loved by the public. However, most of the handheld atomizers are generally provided in an integrated structure, and do not have the function of quickly switching from a handheld use state to a wearable use state. When a patient switches from a handheld use state to a wearable use state, the device can only be tied to the head by two ear bands. However, due to the large weight of the integrated handheld atomizer, when the atomization administration device is worn on the head of the patient by means of the ear bands, the pressure on the head of the patient is too large, thereby reducing the comfort of the patient. Therefore, the present application provides a handheld medical atomization administration device to meet the needs. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a handheld medical atomization administration device. By providing the mounting and connecting mechanism, the base body, the medicine box body and the administration device body can be quickly and stably connected together for use. The mounting and connecting mechanism also considers the stability of the elderly or people with weak hands when holding the device. The user can easily hold the device. When the device needs to be worn, the components in the mounting and connecting mechanism can be removed and reorganized to convert the device into a wearable state for use. The above settings can solve the problem of inconvenient wearing of the handheld atomizer.

[0005] To solve the above technical problems, the present application provides the following technical solutions: A handheld medical atomization administration device, comprising a base body, a storage cavity is formed in the base body, a connecting line body is installed on the top of the base body, a medicine box body is installed on the top of the base body, an administration device body is installed at the bottom of the medicine box body, a connecting mechanism body is installed on one side of the medicine box body, a face mask body is installed on the side away from the medicine box body of the connecting mechanism body, a ventilation opening is formed in the top of the base body, and a control screen body is installed on the base body; a mounting and connecting mechanism is used to connect the base body, the medicine box body and the administration device body together, and the mounting and connecting mechanism is connected with the base body.

[0006] Optionally, the base body is provided with a first limiting groove, and the drug delivery device body is provided with a third limiting groove.

[0007] Optionally, the installation and connection mechanism includes a first limiting frame mounted on the base body, a connecting skeleton mounted on the top of the first limiting frame, a third limiting frame fixedly connected to the bottom of the connecting skeleton away from the first limiting frame, a connecting piece fixedly connected to the top of the connecting skeleton, a fourth limiting groove formed on the connecting piece, a limiting block adapted to the shape of the fourth limiting groove fixedly connected to the top of the medicine box body, and a second limiting groove adapted to the shape of the connecting piece formed on the top of the medicine box body.

[0008] Optionally, the connecting mechanism body is adapted to the contour shape of the patient's mouth and nose, and the edges of the connecting mechanism body are made of silicone material.

[0009] Optionally, the connecting frame is an arc-shaped structure that protrudes away from the body of the medicine box, and a second limiting frame is provided on the connecting frame.

[0010] Optionally, the shape of the first limiting frame is adapted to the shape of one side of the first limiting groove and the third limiting groove, and the shape of the third limiting frame is adapted to the shape of the other side of the first limiting groove and the third limiting groove.

[0011] Optionally, the first limiting frame is provided with a first lightweight groove, and the third limiting frame is provided with a third lightweight groove.

[0012] Optionally, a limiting strip body is installed at the top and bottom of the first limiting frame. The limiting strip body has a groove, a guide portion is provided on the side of the limiting strip body away from the base body, and a limiting portion is provided on the side of the limiting strip body close to the guide portion.

[0013] Optionally, a first cavity is provided on the side of the limiting strip body near the base body, and a second cavity is provided on the side of the limiting strip body near the limiting part. The first cavity and the second cavity are interconnected, and the limiting strip body is made of rubber.

[0014] Optionally, the first limiting frame, the connecting skeleton, the third limiting frame, and the connecting piece are made of plastic. The first limiting frame has a weakening part near its central axis, and the outer edge of the first limiting frame is arc-shaped.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up an installation and connection mechanism, not only can the base body, medicine box body and drug delivery device body be quickly and stably connected together for use, but the installation and connection mechanism also takes into account the stability of the grip when the elderly or people with weak hands hold the device, allowing users to easily grip the device for use. Furthermore, when the device needs to be worn, the components in the installation and connection mechanism can be removed and the device disassembled and reassembled, and the internal structure of the device can be converted into a wearable state for use, making the structure worn on the patient's face lighter, thereby improving the patient's comfort.

[0016] By incorporating a first limiting frame and a third limiting frame within the installation and connection mechanism, not only can the base body and the drug delivery device body be quickly and tightly connected together, but the first and third limiting frames also enhance the anti-slip properties of the outer walls of the base body and the drug delivery device body, allowing the device to stably conform to the patient's hand. This enables the patient to hold the device securely in their hand for use. The coordinated use of the structures effectively improves the handheld use of the installation and connection mechanism, and the structure is simple and practical.

[0017] By setting a connecting skeleton and a connecting piece in the installation and connection mechanism, not only can the main body of the medicine box and the main body of the drug delivery device be tightly connected together, but the connecting skeleton and the third limiting frame are also locked on the main body of the drug delivery device. The connecting skeleton is in a state of being folded towards the center, and the third limiting frame and the limiting strip are in a state of being folded towards the center of the main body of the drug delivery device, thereby making the main body of the medicine box and the main body of the drug delivery device tightly connected together.

[0018] By incorporating a limiting strip body within the installation and connection mechanism, when the patient's hand grips the first and third limiting frames, their index finger and little finger are placed within the two limiting strip bodies respectively. The limiting strip bodies can clamp and limit the patient's fingers, allowing the patient to easily hold the device. This makes the device suitable for people with poor hand grip strength. A guide portion is provided on the side of the limiting strip body away from the base body. The guiding effect of the guide portion makes it easier for the patient's fingers to be locked in the groove. A limiting portion is provided on the side of the limiting strip body near the guide portion. The limiting portion clamps and limits the side of the patient's fingers, further ensuring that the fingers are more stably locked in the groove.

[0019] In summary, through the installation and connection mechanism and the cooperation of its various components, the structure of this nebulizer can be quickly disassembled, and the disassembled structure can be stably spliced ​​together. This facilitates quick switching between handheld and worn modes of use. Furthermore, the device is suitable for people with poor hand grip. The overall structure of the nebulizer is simple, convenient and quick to use, and has low production costs, making it practical and easy to promote and use.

[0020] In this technical solution, by replacing the nebulization module with microporous nebulizing plates of different pore sizes, the nebulizer can produce mist particles of different sizes, which can be applied to different diseased sites to achieve precise treatment of diseases by region. Furthermore, this device can be connected to mobile devices via Bluetooth, and the client can detect and record the nebulization status. The structure of this device is relatively simple, making it convenient and quick to carry and use when going out. The device has good practicality and is easy to promote and use.

[0030] like Figures 1 to 3As shown, an embodiment of the present invention provides a handheld medical nebulizer, including a base body 1, a storage cavity 2 inside the base body 1, a connecting cable body 4 installed on the top of the base body 1, a medicine box body 5 installed on the top of the base body 1, a drug delivery device body 11 installed at the bottom of the medicine box body 5, a connecting mechanism body 7 installed on one side of the medicine box body 5, a mask body 8 installed on the side of the connecting mechanism body 7 away from the medicine box body 5, a vent 10 opened on the top of the base body 1, and a control screen body 22 installed on the base body 1.The mounting connection mechanism connects the base body 1, the medicine box body 5, and the drug delivery device body 11. The mounting connection mechanism is connected to the base body 1. The top of the base body 1 has a slot, and the bottom of the drug delivery device body 11 has an insert. The slot and insert are used together to quickly and initially connect the base body 1 and the drug delivery device body 11. An atomizing module is installed inside the drug delivery device body 11. The bottom of the medicine box body 5 has a mounting groove, and the top of the drug delivery device body 11 has an mounting strip. The mounting groove and mounting strip are magnetically connected. The mounting groove and mounting strip are used together to connect the medicine box body 5. The body 5 and the drug delivery device body 11 are quickly and initially connected together. The base body 1 contains a battery and is rechargeable. The charging port is located at the bottom of the base body 1. The base body 1 contains a data recording module and a control module, both of which are existing mature technologies and will not be elaborated upon here. The drug delivery device body 11 is equipped with replaceable microporous atomizing plates. The working principle and specific installation structure of the microporous atomizing plates are existing mature technologies and will not be elaborated upon here. By replacing the atomizing module with microporous atomizing plates containing different pore sizes, atomized particles of different sizes are generated, acting on different diseased areas to achieve precise treatment of diseases by region. This device can connect to mobile devices via Bluetooth, allowing the client to detect and record nebulization. The mask body 8 can be quickly attached to one side of the medicine box body 5 and the connecting mechanism body 7 using the connecting mechanism body 7. The specific structure of the connecting mechanism body 7 is based on existing mature technology and will not be elaborated upon here. Different models of the connecting mechanism body 7 can be replaced depending on the usage. A breathing sensor is installed inside the base body 1, which pauses nebulization when the patient exhales, thereby minimizing drug waste. The breathing sensor is also based on existing mature technology and will not be elaborated upon here. When the device is used handheld… The base body 1, medicine box body 5, and dispensing device body 11 are quickly and stably connected together using an installation and connection mechanism. This mechanism also considers the stability of the grip for elderly people or those with weak hands, allowing users to easily hold the device. When the device needs to be worn, simply remove and reassemble the components within the installation and connection mechanism to convert it into a wearable state. The specific structure and working principle of the installation and connection mechanism are detailed below. This device has a simple structure, is convenient and quick to use, and has good practicality, making it easy to promote and use.

[0031] Furthermore, the connecting mechanism body 7 is adapted to the contour shape of the patient's mouth and nose. The edges of the connecting mechanism body 7 are made of silicone material. Through the shape design of the connecting mechanism body 7, the connecting mechanism body 7 and the patient's skin can fit closely, thereby enhancing the atomization treatment effect of the device. In addition, the silicone material is skin-friendly, so the patient feels more comfortable when using this device. Moreover, the structure is simple, and the cooperation between the structures further improves the effect of the device.

[0032] like Figures 3 to 7 As shown, the base body 1 has a first limiting groove 3, and the drug delivery device body 11 has a third limiting groove 12. The installation and connection mechanism includes a first limiting frame 13 installed on the base body 1. A connecting frame 16 is installed on the top of the first limiting frame 13. A third limiting frame 18 is fixedly connected to the bottom of the connecting frame 16 away from the first limiting frame 13. A connecting piece 20 is fixedly connected to the top of the connecting frame 16. A fourth limiting groove 21 is opened on the connecting piece 20. A limiting block 6 that matches the shape of the fourth limiting groove 21 is fixedly connected to the top of the medicine box body 5. A second limiting groove 9 that matches the shape of the connecting piece 20 is opened on the top of the medicine box body 5. Limiting strip bodies 15 are installed on both the top and bottom of the first limiting frame 13. Figure 3 and Figure 4 As shown, when the top of the base body 1 and the bottom of the drug delivery device body 11 are in contact, the first limiting groove 3 and the third limiting groove 12 are connected and connected to form an integral limiting groove. The structure formed by the first limiting groove 3 and the third limiting groove 12 is adapted to the structural shape formed by the third limiting groove 12 and the third limiting frame 18. The bottom of the connecting frame 16, away from the third limiting frame 18, is fixedly connected to the top of a limiting strip body 15. Figure 6 As shown, a top limiting strip body 15 is connected to the first limiting frame 13 via Velcro. Both the limiting strip body 15 and the first limiting frame 13 have a Velcro strip. The first limiting frame 13 consists of two overlapping pieces. A soft magnetic tab is located on one edge of each first limiting frame 13, ensuring a tight connection when the two pieces are overlapped. Figure 11The mask body 8 shown has Velcro patches on both sides. The first limiting frame 13 has another Velcro patch on one side that matches the shape of the Velcro patch on the mask body 8. By using the first limiting frame 13, the connecting frame 16 and the third limiting frame 18 together, the base body 1, the medicine box body 5 and the drug delivery device body 11 can be quickly and tightly connected together. With the use of the limiting strip body 15, the device can be easily held by the patient. The limiting block 6 is placed in the fourth limiting groove 21 and the connecting piece 20 is placed in the second limiting groove 9. The use of the connecting frame 16 and the connecting piece 20 further makes the connection between the device structures tighter. The limiting strip body 15 clamps and limits the patient's fingers, further making the device fit stably against the patient's hand. The patient can hold the device stably with less force, making the device more convenient to use. The structure is simple, and the cooperation between the structures further improves the device's performance.

[0033] like Figures 7 to 11 As shown, the first limiting frame 13, the connecting skeleton 16, the third limiting frame 18, and the connecting piece 20 are all made of plastic. Plastic is a relatively strong material with good deformation capacity and malleability. The connecting skeleton 16 is an arc-shaped structure that protrudes away from the medicine box body 5. Utilizing the shape design of the connecting skeleton 16, it works in conjunction with other structures within the device. When connecting and fixing the drug delivery device body 11 and the medicine box body 5, it has a tendency to deform inwards, making the connection of the device tighter. A second limiting frame 17 is provided on the connecting skeleton 16, reducing its weight and simultaneously increasing its deformation capacity. Even better, the shape of the first limiting frame 13 is adapted to the shape of one side of the first limiting groove 3 and the third limiting groove 12, and the shape of the third limiting frame 18 is adapted to the shape of the other side of the first limiting groove 3 and the third limiting groove 12. The first limiting frame 13 is provided with a first lightweight groove 14, which reduces the weight of the first limiting frame 13 and also enhances the deformation capability of the first limiting frame 13, so that the first limiting frame 13 can quickly deform under different usage conditions. The third limiting frame 18 is provided with a third lightweight groove 19, which reduces the weight of the third limiting frame 18 and enhances the deformation capability of the third limiting frame 18.

[0034] Furthermore, this device has two operating states, such as... Figure 1As shown, in the first usage state, the base body 1, the drug delivery device body 11, and the medicine box body 5 are tightly fitted together using connecting components. The first limiting groove 3 and the third limiting groove 12 form an integrated limiting groove. The first limiting frame 13 and the third limiting frame 18 are engaged in the groove formed by the first limiting groove 3 and the third limiting groove 12. The limiting block 6 is engaged in the fourth limiting groove 21. The connecting piece 20 is engaged in the second limiting groove 9. The connecting frame 16 is in a state of being folded towards the center. A limiting strip body 15 at the top is connected to the first limiting frame 13 by Velcro. Each of the limiting strip body 15 and the first limiting frame 13 has a Velcro piece. The first limiting frame 13 consists of two overlapping pieces. A soft magnetic suction piece is provided on one side edge of the frame 13, so that the two first limiting frames 13 are tightly connected when they are stacked together. The structure formed by the first limiting frame 13 and the third limiting frame 18 tends to converge towards the center of the base body 1, so that the base body 1, the drug delivery device body 11 and the medicine box body 5 are tightly connected together. The mask body 8 is installed on one side of the medicine box body 5 and the drug delivery device body 11 through the connecting mechanism body 7. When using nebulization, the patient holds the first limiting frame 13 and the third limiting frame 18 with their hand, and places their index finger and little finger in the two limiting strip bodies 15 respectively. The limiting strip bodies 15 are used to hold and limit the patient's fingers, so that the patient can easily hold the device, thus making the device suitable for handheld use by different people.

[0035] like Figure 9As shown, in the second usage state, the medicine box body 5 and the drug delivery device body 11 are connected together, the base body 1 is separated, the first limiting frame 13 is separated from a limiting strip body 15, the two first limiting frames 13 that were originally stacked together unfold into two separate individuals and are respectively installed on both sides of the mask body 8, the limiting block 6 is engaged in the fourth limiting groove 21, the connecting piece 20 is engaged in the second limiting groove 9, and the connecting frame 16, in conjunction with the use of the third limiting frame 18, tightly connects the medicine box body 5 and the drug delivery device body 11 together. At this time, the connecting frame 16 and the third limiting frame 18 are engaged in the third limiting groove 12 opened on the drug delivery device body 11, the connecting frame 16 is in a state of being folded towards the center, and the third limiting frame 18 and the limiting strip body 15 are in a state of being folded towards the center of the drug delivery device body 11. Due to the first limiting... The first lightweight groove 14 on the frame 13 forms a side strip at a convenient location on the first limiting frame 13. The outer edge of the side strip is arc-shaped and wrapped with cotton pads. After bending and deforming the two side strips of the first limiting frame 13, they are hung on the ears with gentle pressure. The first limiting frame 13 is subjected to tensile force and undergoes a certain deformation, so that the edge of the first limiting frame 13 fits against the patient's skin, and the edge of the mask body 8 fits tightly against the patient's skin. The device under this device is used by the patient to wear, which can free the patient's hands and make the device more convenient to use. When wearing the device, it is not necessary to wear the entire device. The base body 1 and the drug delivery device body 11 are connected by the connecting line body 4. When wearing the device, the base body 1 can be placed aside. This makes the weight of the device on the patient's face less, thus making the patient more comfortable.

[0036] Furthermore, the limiting strip body 15 has a groove 23, which facilitates the user to insert their fingers into the first limiting frame 13. This allows the limiting strip body 15 to assist in limiting the patient's hand, enabling patients with weak hand grip to easily and stably hold and use the device. A guide portion 24 is provided on the side of the limiting strip body 15 away from the base body 1, which helps the patient's fingers to be more easily engaged in the groove 23. A limiting portion 27 is provided on the side of the limiting strip body 15 near the guide portion 24, which clamps and limits the side of the patient's fingers, further ensuring the fingers are more stably engaged in the groove 23. A first cavity 25 is provided on the side of the limiting strip body 15 near the base body 1, and a second cavity 26 is provided on the side of the limiting strip body 15 near the limiting portion 27. The first cavity 25 and the second cavity 26 are interconnected. The combined use of 6 enhances the deformation capability of the limiting strip body 15, allowing it to elastically deform according to the shape of the patient's fingers when compressed. The limiting strip body 15 is made of rubber, which is relatively soft and has good deformation capability, making it easier for the limiting strip body 15 to deform when compressed. The first limiting frame 13 has a weakening part 28 near its central axis, so that the first limiting frame 13 deforms first from the weakening part 28 under the action of external force, allowing the first limiting frame 13 to bend under force and fit against the patient's facial skin. The outer edge of the first limiting frame 13 is arc-shaped without obvious sharp edges, preventing the first limiting frame 13 from accidentally scratching the patient's skin during use. Moreover, the above structure is simple, and the combination of the structures further improves the effectiveness of the device, making the device more practical.

[0037] The working principle of the technical solution provided by this invention is as follows: In use, when the device needs to be held by hand, the top of the base body 1 has a slot, and the bottom of the drug delivery device body 11 has an insert. The slot and insert are used to initially connect the base body 1 and the drug delivery device body 11. An atomizing module is installed inside the drug delivery device body 11. Before connecting the medicine box body 5 and the drug delivery device body 11, the microporous atomizing plate inside the drug delivery device body 11 is replaced with the required diameter. Then, the mounting groove at the bottom of the medicine box body 5 and the mounting strip at the top of the drug delivery device body 11 are used for magnetic connection, initially connecting the medicine box body 5 and the drug delivery device body 11. After the base body 1, the drug delivery device body 11, and the medicine box body 5 are initially tightly fitted together, the first limiting groove 3 and... The third limiting groove 12 forms an integrated limiting groove. Then, the first limiting frame 13 and the third limiting frame 18 are engaged in the groove formed by the first limiting groove 3 and the third limiting groove 12, so that the limiting block 6 is engaged in the fourth limiting groove 21, the connecting piece 20 is engaged in the second limiting groove 9, and the connecting frame 16 is in a state of being folded towards the center. The structure formed by the first limiting frame 13 and the third limiting frame 18 also tends to fold towards the center of the base body 1. The cooperation between the structures makes the base body 1, the drug delivery device body 11 and the medicine box body 5 tightly connected together. The mask body 8 is installed on one side of the medicine box body 5 and the drug delivery device body 11 through the connecting mechanism body 7, and then handheld nebulization is performed. The patient holds the first limiting frame 1 in their hand. 3 and the third limiting frame 18, the index finger and little finger are respectively placed in the two limiting strip bodies 15, the limiting strip bodies 15 are used to clamp and limit the patient's fingers, and at the same time the limiting strip bodies 15 also have a tendency to converge towards the center of the base body 1, further enhancing the tightness of the connection between the device structures. The use of the limiting strip bodies 15 and other structures makes it easy for the patient to hold the device, thus making the device suitable for hand-held use by different people. Then, when the patient needs to wear and use this device, the medicine box body 5 and the drug delivery body 11 remain connected, and then the base body 1 is separated separately. Then the first limiting frame 13 is removed from one of the top limiting strip bodies 15, and then the two first limiting frames that were originally stacked together are removed. The body 13 is separated into two individual units. The individual first limiting frame 13 is then attached to both sides of the mask body 8 via Velcro. At this time, the limiting block 6 remains engaged in the fourth limiting groove 21, and the connecting piece 20 is engaged in the second limiting groove 9. The cooperation of the connecting frame 16 and the third limiting frame 18 tightly connects the medicine box body 5 and the drug delivery device body 11 together. The connecting frame 16 and the third limiting frame 18 are engaged in the third limiting groove 12 on the drug delivery device body 11. The connecting frame 16 is in a state of convergence towards the center, and the third limiting frame 18 and the limiting strip body 15 are in a state of convergence towards the center of the drug delivery device body 11, thus tightly connecting the medicine box body 5 and the drug delivery device body 11 together.The two side strips of the first limiting frame 13 are gently attached to the ears, and the edges of the first limiting frame 13 are fitted against the patient's face, ensuring that the edge of the mask body 8 is tightly fitted against the patient's skin. When the device is worn, the base body 1 is placed aside. This device can be worn by the patient or held in hand, allowing for easy gripping of the main body and freeing the patient's hands, making it more convenient to use. Furthermore, the device has a simple structure and is relatively easy and quick to use.
