Description

Technical Field

[0001] The present application relates to the technical field of nebulizers, and in particular to a medical nebulizer nozzle and a medical nebulizer. Background Art

[0002] With the diversification of life and the aggravation of environmental pollution, respiratory diseases have become common diseases nowadays, such as asthma, chronic obstructive pulmonary disease, etc., and the number of patients is still increasing. At present, inhalation drug administration is the simplest and most effective drug administration route for the treatment of respiratory diseases such as asthma and chronic obstructive pulmonary disease. At present, inhalation drug administration is mainly achieved through a nebulizer. When using it, the drug solution is added into the nebulizer and atomized, and the atomized drug solution in the nebulizer is discharged through the nozzle to enter the patient's mouth;

[0003] Existing atomizer nozzles have the following problems when used:

[0004] First, in order to be better held by the patient, it will extend from the side wall of the nebulizer, so that a bulge is formed on the side wall of the nebulizer, and then a corner is formed between the inner wall of the nebulizer and the inner wall of the nozzle. When the nebulization is completed and the nebulizer is cleaned, it is difficult to clean the corner, which increases the possibility of residual liquid medicine.

[0005] Secondly, the existing nozzle only has the function of guiding the atomized liquid medicine when in use. When the atomization treatment is completed, the nozzle will be idle and has a relatively single function.

[0023] The beneficial effects of this application are as follows:

[0024] 1. The present application forms a nozzle structure through an extension tube, and a mounting sleeve and a flat sleeve are installed on the extension tube, so that the medicine liquid can be discharged smoothly. When atomization is performed, the cylinder plate is rotated so that the opening of the through cavity is blocked. When cleaning is required, the bristles are brushed and cleaned on the inner wall of the extension tube through the sliding rack and the cooperation of the teeth.

[0026] 3. In the present application, when the patient's lung condition improves, the blowing ball may be blown to the top of the cavity in the middle stage of recovery. At this time, the connecting rod is pulled outward to connect the external air hole with the outside world, so that when the patient blows air into the cavity, part of the air flow will enter the inner cavity and then be discharged outward through the external air hole. At this time, greater force is required to blow air to make the blowing ball move upward, which increases the practicality of the device.

[0027] 4. When the present application is in use, when the device needs to add medicine, the resistance plate is in a position away from the rotating plate. At this time, the rotation of the rotary cover is not restricted, which is convenient for adding medicine. When the device needs to perform blowing exercise, the rotating cylinder plate drives the resistance plate to resist the rotating plate, so that one side of the rotating plate is away from the mounting shell, and the other end drives the limiting plate close to the mounting shell, thereby resisting the rotary cover and restricting the rotation of the rotary cover. When the device is blowing, there is no need to free up hands to stabilize the rotary cover so that it cannot rotate, thereby increasing the convenience of the device.

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Embodiment 1

[0044] like Figure 1 - Fig.12 As shown, the medical nebulizer nozzle proposed in the first embodiment of the present application includes:

[0045] The installation shell 1 has an extension tube 101 installed on its side wall, and the extension tube 101 is connected to the inside of the installation shell 1. The installation shell 1 is provided with a drug adding port 102 for the drug liquid to pass through. When in use, the drug liquid is injected into the installation shell 1 through the drug adding port 102. The extension tube 101 is installed on the side wall of the installation shell 1 in a direction perpendicular to the axial direction of the installation shell 1, and is used to guide the atomized drug liquid;

[0046] The cleaning member 2 is installed on the extension tube 101. The cleaning member 2 includes a mounting sleeve 201 mounted on the extension tube 101. A rotating rod 202 is rotatably mounted on the mounting sleeve 201. Bristles 203 are mounted on the peripheral side of the rotating rod 202. When the extension tube 101 needs to be cleaned, the rotation of the rotating rod 202 drives the bristles 203 to brush and clean the inner wall of the extension tube 101, thereby reducing the possibility of residual liquid in the extension tube 101, thereby increasing the cleaning effect of the device;

[0047] A plurality of teeth 204 are arranged in a circular array along the axis direction of the rotating rod 202 on the rotating shaft, and a rack 206 is slidably installed on the mounting sleeve 201 through a connecting spring 205, and the rack 206 meshes with the teeth 204. A flat sleeve 207 is installed on the side of the mounting sleeve 201 away from the mounting shell 1. When in use, the rack 206 is pressed to make the rack 206 slide on the mounting sleeve 201, and mesh with the teeth 204, thereby driving the rotating rod 202 to rotate, so that it can drive the bristles 203 to brush the extension tube 101. When the rack 206 is released, the connecting spring 205 is reset, pushing the rack 206 to reset, so that the rotating rod 202 is reversed, so that the bristles 203 clean the inner wall of the extension tube 101 again, further increasing the cleaning effect of the device, and also facilitating the cleaning of the extension tube 101.

[0048] The flat sleeve 207 is used to reduce the opening size of the extension tube 101, making it easier for the patient to hold it in his mouth, thereby increasing the practicality of the device;

[0049] The blowing member 3 is mounted on the mounting shell 1. The blowing member 3 includes an L-shaped plate 301 mounted on the mounting shell 1. The angle between the L-shaped plate 301 and the extension tube 101 is 180°. The L-shaped plate 301 is provided with a through cavity 302 connected to the inside of the mounting shell 1. A shielding plate 303 is installed in the through cavity 302. A vent hole 304 for air flow is provided on the shielding plate 303. A blowing ball 305 is installed above the shielding plate 303 in the through cavity 302. A through hole 306 is provided on the L-shaped plate 301 to connect the through cavity 302 with the outside world. Figure 1 From the main perspective, the shielding plate 303 is located at one end of the L-shaped plate 301 in the vertical direction. Since the nebulizer is mostly used to treat patients with lung diseases, it is also necessary to perform recovery exercises on the lungs during the treatment. When the patient's nebulization treatment is completed or ended, air is blown into the mounting shell 1 through the flat sleeve 207, so that the airflow enters the through cavity 302, and the airflow passes through the vent hole 304 and the shielding plate 303 to blow the blowing ball 305. The blown airflow is discharged to the outside of the through cavity 302 through the through hole 306, so that the patient can exercise the lungs, thereby increasing the practicality of the device;

[0050] The barrel plate 4 is rotatably mounted on the mounting shell 1. A connecting hole 401 is provided on the barrel plate 4. There are three connecting holes 401, and the angle between adjacent connecting holes 401 is 90°. When the barrel plate 4 rotates, it is used to block or unblock the opening of the through cavity 302. A cover plate 402 is installed on the barrel plate 4. An injection port 403 connected to the drug adding port 102 is provided on the cover plate 402. A rotating cover 404 is rotatably mounted on the cover plate 402. An inlet 405 is provided on the rotating cover 404. When the device needs to be atomized, the barrel plate 4 is rotated so that one of the connecting holes 401 is aligned with the extension tube 101, and the side without the connecting hole 401 blocks the opening of the through cavity 302. For the convenience of subsequent description, this state is set as the atomization state of the device, so that the drug liquid cannot enter the through cavity 302, thereby reducing the waste of the drug liquid.

[0051] When in use, the rotary cover 404 is rotated to align the inlet port 405 thereon with the injection port 403, and the barrel plate 4 is rotated to cover the opening of the through cavity 302, and the liquid medicine is added into the mounting shell 1, and then the rotary cover 404 is rotated to make the inlet port 405 and the injection port 403 misaligned, so as to reduce the possibility of liquid medicine waste. After atomization is completed, the inside of the extension tube 101 is cleaned by sliding the rack 206. When the cleaning is completed and it is necessary to perform blowing exercise, the rotary cover 404 continues to keep the inlet port 405 and the injection port 403 misaligned, and the barrel plate 4 is rotated to make the connecting hole 401 communicate with the opening of the through cavity 302. For the convenience of subsequent description, this state is set as the blowing state of the device, and then the remaining openings on the mounting shell 1 are covered by hands or other airtight objects to maintain the airtightness of the device. At this time, the patient can blow air to exercise the lungs, which increases the practicality of the device.

[0052] Compared with the prior art, the nozzle structure is formed by the extension tube 101, and the installation sleeve 201 and the flat sleeve 207 are installed on the extension tube 101, so that the medicine can be discharged smoothly. When atomization is performed, the cylinder plate 4 is rotated so that the opening of the through cavity 302 is blocked. When cleaning is required, the bristles 203 are brushed and cleaned on the inner wall of the extension tube 101 through the sliding rack 206 and the cooperation of the teeth 204. When the atomization treatment is completed, the cylinder plate 4 is rotated to connect the extension tube 101 with the through cavity 302. At this time, the blowing ball 305 can be floated in the through cavity 302 by blowing air, which plays a role in exercising the lungs and increases the practicality of the device. Embodiment 2

[0053] like Figure 2 , Fig.10 and Fig.12As shown, the second embodiment further discloses the cleaning member 2, the blowing member 3 and the cylinder plate 4 on the basis of the first embodiment. In the second embodiment, the installation sleeve 201 is provided with an inserting plate 5 for inserting into the extension tube 101. When in use, the inserting plate 5 is inserted into the inner wall of the extension tube 101, thereby increasing the contact area between the installation sleeve 201 and the extension tube 101, and thus increasing the connection strength between the two.

[0054] An elastic plate 6 is installed on the installation sleeve 201, and a blocking block 7 is installed on the extension tube 101. When the elastic plate 6 conflicts with the blocking block 7, the tendency of the installation sleeve 201 to move away from the extension tube 101 is restricted. The bristles 203 are arranged in a ring shape on the rotating rod 202. The diameter of the bristles 203 facing the installation shell 1 is smaller than the diameter of the side away from the installation shell 1. When the installation sleeve 201 is disconnected from the extension tube 101, the inner wall of the extension tube 101 is scraped by the side with the larger diameter of the bristles 203, which further increases the cleaning effect. The elastic plate 6 is L-shaped. When the installation sleeve 201 is inserted into the extension tube 101, the elastic plate 6 is moved so that it can pass through the blocking block 7. When the installation sleeve 201 is inserted When it is set to the maximum limit, the elastic plate 6 is loosened. The elastic plate 6 is now blocked by the blocking block 7, thereby limiting the tendency of the mounting sleeve 201 to separate from the extension tube 101. When the mounting sleeve 201 needs to be removed, the elastic plate 6 is also bent to deform it to a degree that it can pass through the blocking block 7, and the mounting sleeve 201 is pulled outward to release the connection between the mounting sleeve 201 and the extension tube 101. The mounting sleeve 201 and the extension tube 101 are detachably connected, so that after cleaning, the mounting sleeve 201 can be released from the extension tube 101, and the two can be separated and dried, thereby reducing the possibility of water remaining on the bristles 203 causing bacterial growth, and further increasing the cleaning effect of the device.

[0055] like Figure 6 As shown, in the second embodiment, a connecting rod 8 is movably inserted on the L-shaped plate 301, an inner cavity 9 is provided on the connecting rod 8, and a plurality of outer air holes 10 penetrating through the side wall of the connecting rod 8 are provided on the side wall of the connecting rod 8. When the connecting rod 8 slides in the inner cavity 9, the outer air holes 10 are connected or disconnected with the outside world. When the patient performs lung exercises and the patient's lung condition improves, the blowing ball 305 may be blown to the top of the through cavity 302 in the middle stage of recovery. At this time, the connecting rod 8 is pulled outward to connect the outer air holes 10 with the outside world, so that when the patient blows air into the through cavity 302, part of the air flow will enter the inner cavity 9 and then be discharged outward through the outer air holes 10. At this time, a greater force is required to blow air to make the blowing ball 305 move upward, thereby increasing the practicality of the device.

[0056] Moreover, the external air holes 10 are linearly arrayed on the connecting rod 8 along the axial direction of the connecting rod 8. By pulling outward at different distances, the area connected to the outside world is gradually increased, thereby increasing the intensity of exercise. The exercise intensity of the device can be adjusted according to the patient's recovery degree, further increasing the practicality of the device.

[0057] like Figure 3 , Figure 6 and Fig. 9 As shown, in the second embodiment, the cylinder plate 4 is provided with a resisting plate 11. Since there are three communicating holes 401 and the angles between them are 90°, there must be two communicating holes 401 aligned with each other. In the vertical direction, the resisting plate 11 is in a straight line with one of the communicating holes 401 aligned with each other, that is, the device is in a blowing state at this time.

[0058] A rotating plate 12 is hinged on the L-shaped plate 301, one end of the rotating plate 12 is used to contact the contact plate 11, and the other end is hinged to a limiting plate 13, a return spring 14 is installed between the limiting plate 13 and the L-shaped plate 301, and the free end of the limiting plate 13 is used to contact the rotating cover 404. When the device needs to add medicine, the contact plate 11 is in a position away from the rotating plate 12, and the rotation of the rotating cover 404 is not restricted, so that the addition of medicine is convenient;

[0059] When the device needs to perform air blowing exercise, the rotating plate 4 is rotated to drive the resisting plate 11 to resist the rotating plate 12, so that one side of the rotating plate 12 is away from the mounting shell 1, and the other end drives the limiting plate 13 to approach the mounting shell 1, thereby resisting the rotating cover 404, and limiting the rotation of the rotating cover 404, so that when the device is blowing, there is no need to free up hands to stabilize the rotating cover 404 so that it cannot rotate, which increases the convenience of the device;

[0060] When the abutting plate 11 rotates to release the abutment with the rotating plate 12 , the return spring 14 pulls the limiting plate 13 to return to its original position, so that the limiting plate 13 releases the abutment with the rotating cover 404 .

[0061] like Figure 4 and Figure 8 As shown, in the second embodiment, the cylinder plate 4 includes a cylinder base plate 406 and an upper ring plate 407, the communication hole 401 is provided on the cylinder base plate 406, the cover plate 402 and the contact plate 11 are both installed on the upper ring plate 407, the upper ring plate 407 is provided with a limited rotation rod 15, the limited rotation rod 15 slides through the cylinder base plate 406, the mounting shell 1 is provided with an atomizing hole 16 and an air blowing hole 17 for accommodating the limited rotation rod 15, when the limited rotation rod 15 is inserted in the atomizing hole 16, the communication hole 401 is disconnected from the opening of the through cavity 302, when the limited rotation rod 15 is inserted in the air blowing hole 17, the communication hole 401 is connected to the opening of the through cavity 302, so as to Figure 1From the main perspective, the upper ring plate 407 is slidably installed on the barrel base plate 406 in the vertical direction. When the barrel plate 4 is adjusted, the upper ring plate 407 is first slid to make the limiting rod 15 away from the bottom of the barrel base plate 406, reducing the influence of the limiting rod 15 on the rotation of the barrel plate 4. If the device needs to be atomized, the barrel plate 4 is rotated and the limiting rod 15 is inserted into the atomization hole 16. At this time, the barrel base plate 406 blocks the opening of the through cavity 302, and the device is in the atomization state. When the device needs to be blown, the barrel base plate 406 is rotated and the limiting rod 15 is inserted into the blowing hole 17. At this time, the connecting hole 401 connects the through cavity 302 with the inside of the mounting shell 1. At this time, the device is in the blowing state. When in use, the limiting rod 15 is blocked by the inner wall of the blowing hole 17 or the atomization hole 16, thereby limiting the rotation of the barrel plate 4, making the device more stable when performing blowing exercises or atomizing, thereby increasing the practicality of the device.

[0062] like Figure 5 , Figure 6 and Figure 7 As shown, in the second embodiment, an arc groove 18 is provided on the connecting rod 8, and the arc groove 18 is connected to one of the outer air holes 10. A fixing rod 19 is installed on the mounting sleeve 201, and an expansion plate 20 is installed on the free end of the fixing rod 19. The diameter of the expansion plate 20 is larger than the rod diameter of the fixing rod 19 and smaller than the aperture of the outer air hole 10. The groove width of the arc groove 18 is smaller than the diameter of the expansion plate 20 and larger than the rod diameter of the fixing rod 19. The connecting rod 8 can rotate and slide on the L-shaped plate 301. When the mounting sleeve 201 is disassembled and assembled too many times, the shielding block 7 and the elastic plate 6 are worn more. When the patient needs to increase the blowing intensity, the force of the airflow impact increases. It is easy to make the installation sleeve 201 and the extension tube 101 fall off, therefore, the connecting rod 8 is pulled to the outside of the through cavity 302, the connecting rod 8 is rotated so that the outer air hole 10 faces the extension tube 101, and then the installation sleeve 201 is inserted into the extension tube 101, so that the fixing rod 19 drives the expansion plate 20 to be inserted into the outer air hole 10, and the connecting rod 8 is rotated so that the outer air hole 10 is rotated to a direction away from the extension tube 101. At this time, the fixing rod 19 is located in the arc groove 18, and the expansion plate 20 is blocked by the edge of the arc groove 18, further limiting the tendency of the installation sleeve 201 to separate from the extension tube 101, thereby further increasing the practicality of the device;

[0063] When in use, the connecting rod 8 and the external air hole 10 can not only adjust the patient's exercise intensity, but also enhance the installation strength of the installation sleeve 201, thereby increasing the practicability of the device. Embodiment 3

[0064] like Figure 1 - Fig.12As shown, the third embodiment further discloses the present application on the basis of the second embodiment.
