[0034] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0035] In the description of the present invention, it should be understood that the terms "center", "length", "width", "height", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "side" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0036] See also Figure 1 As stated, Figure 1 It is a structural schematic diagram of the Dubao device 100 in the prior art. The Dubao device (a kind of inhalation medication device) includes a bottle body 102 and a rotating base 101, and a suction nozzle 103 is arranged on the top of the bottle body 102. When in use, it is necessary to hold the bottle body with one hand and the rotating base 101 with the other hand, rotate the rotating base 101 to the bottom in a certain direction, and then rotate it to the bottom in the opposite direction after hearing a "click" sound. Repeat twice to turn on the device. Take the bottle body vertically, repeat the above steps of rotating the rotating base 101, and hear a "click" sound once, that is, the drug application is completed (each rotation completes the drug application of one dose). After the drug application is completed, you can wrap your lips around the suction nozzle 103 and inhale deeply and deeply, and the drug is directly delivered to the lungs for treatment. If the base is not rotated to apply the drug before inhaling the drug, no drug will reach the suction nozzle, the drug cannot be administered, and the patient cannot inhale the drug into the lungs. Therefore, rotating the rotating base 101 to apply the drug is a necessary operation before inhaling the drug. In the prior art, the inhalation medication device, such as the Dubao device, needs to manually rotate the rotating base 101 of the inhalation medication device to complete the medication operation before inhaling the medication. This is inconvenient for the user to use and the medication operation is cumbersome, especially for elderly users.

[0037] In view of the above problems, the embodiments of the present invention provide a medication application device and a medication application system for inhalation, which do not require manual rotation of the rotating base 101, assist the patient in completing the medication application operation, and are easy to use.

[0038] Combine the following Figure 2-Figure 8 The technical solution provided by the present invention is described in more detail.

[0039] Embodiment 1:

[0040] like Figure 2-Figure 8As shown, the medication application device provided by the present invention includes a shell, a driving mechanism located inside the shell and a fixed seat 3, wherein: the shell is used to accommodate an inhalation medication device, and the two are detachably connected, and the shell allows the nozzle of the inhalation medication device to extend; the fixed seat 3 is positioned and connected to the rotating base 101 of the inhalation medication device, and after the fixed seat 3 and the rotating base 101 are connected in place, the two can rotate synchronously; the driving mechanism is transmission-connected to the fixed seat 3, and is used to drive the fixed seat 3 to rotate, thereby driving the rotating base 101 to rotate, and then completing the medication application.

[0041] The inhalation medication device may be the Dubao device 100 in the prior art (a type of inhalation medication device). As an existing mature technology, it will not be described in detail here.

[0042] The medication applying device of this embodiment installs the inhalation medication device into a shell, and the base of the inhalation medication device is positioned and connected with the fixing base 3. When the medication applying operation is required, the driving mechanism in the shell drives the fixing base 3 to rotate, thereby driving the rotating base 101 to rotate left or right, thereby completing the medication applying of the inhalation medication device. At this time, the user can hold the mouthpiece in his mouth for inhalation medication without manually rotating the rotating base 101, which is convenient to use.

[0043] As an alternative embodiment, see Figure 7 and Figure 8 As shown, the fixing seat 3 has an installation cavity with an open upper side, and a raised strip 31 or a recessed strip is provided on the cavity wall of the installation cavity. The raised strip 31 or the recessed strip is arranged at intervals around the central axis of the fixing seat 3, and the raised strip 31 or the recessed strip is meshed with the rib 1011 on the rotating base 101.

[0044] join Figure 1 As shown, the rotating base 101 of the inhalation medication device is provided with ribs 1011 for easy rotation. When the rotating base 101 of the inhalation medication device is installed in the installation cavity, the raised strips 31 or recessed strips on the cavity wall of the installation cavity engage with the ribs 1011 on the rotating base 101. With such a configuration, when the driving mechanism drives the fixed base 3 to rotate in the horizontal direction, the rotating base 101 can rotate synchronously.

[0045] As an alternative embodiment, see Figure 7 and Figure 8 As shown, the driving mechanism includes a first driving device 41 and a gear set 42, wherein: a transmission rod is fixed on the fixed seat 3, a tooth portion 32 is fixed on the periphery of the transmission rod, the gear set 42 and the tooth portion 32 are meshed with each other, and the first driving device 41 is drivingly connected to the gear set 42 to drive the gear set 42 to rotate, thereby driving the fixed seat 3 to rotate in the forward or reverse direction with its axial direction as the rotation axis.

[0046] Among them, the first driving device 41 can be a motor, and the first driving device 41 is meshed with the tooth portion 32 at the bottom of the fixed base 3 through the gear set 42. The first driving device 41 outputs power, and through the deceleration and transmission torque of the gear set 42, the first driving device 41 drives the fixed base 3 to rotate in the forward or reverse direction with the axial direction as the rotating shaft, wherein one of the forward and reverse directions is clockwise, and the other is counterclockwise.

[0047] Since the device 100 (a kind of inhalation medication device) includes a bottle body and a base, and a suction nozzle is arranged on the top of the bottle body. In the prior art, when using it, one needs to hold the bottle body with one hand and the base with the other hand. In order for the driving mechanism of this embodiment to drive the rotating base 101 to rotate through the fixed base 3 to prevent the bottle body from rotating, that is, to realize the relative rotation of the rotating base 101 and the bottle body, see Figure 5 , Figure 6 and Figure 8 As shown, the medication device of this embodiment also includes a clamping mechanism, which is located in the shell. The clamping mechanism includes a moving rod 51. At least two moving rods 51 are provided. The two moving rods 51 can move toward or away from each other, thereby clamping, fixing or releasing the bottle body of the inhalation medication device.

[0048] When the rotating base 101 needs to be rotated, the two moving rods 51 move toward each other and tightly clamp the bottle body of the inhalation medication device. When the rotating base 101 does not need to be rotated, the two moving rods 51 can only play a role in straightening the bottle body.

[0049] Before the driving mechanism drives the fixed seat 3 and the rotating base 101 to rotate, the clamping mechanism of this embodiment is activated, and the two moving rods 51 move toward each other and tightly clamp the bottle body of the inhalation medication device to prevent the bottle body from rotating, so that the driving mechanism drives the fixed seat 3 and the rotating base 101 to rotate in the next step, and the rotating base 101 and the bottle body can rotate relative to each other. The bottle body and the rotating base 101 are prevented from rotating synchronously, and the purpose of applying medicine cannot be achieved.

[0050] As an alternative embodiment, see Figure 5 , Figure 6 and Figure 8 As shown, the clamping mechanism of this embodiment also includes a second driving device 52, which can be a motor. The number and position of the second driving devices 52 correspond to the number and position of the moving rods 51. The output end of the second driving device 52 is provided with driving teeth 53, and the moving rod 51 is provided with tooth grooves 511. The tooth grooves 511 are arranged at intervals along the length direction of the moving rod 51. The driving teeth 53 are meshed with the corresponding moving rod 51, and the moving rod 51 moves along its own axial direction under the drive of the driving teeth 53.

[0051] Specifically, the notch of the tooth groove 511 faces the driving tooth 53. Since the tooth groove 511 on the moving rod 51 is meshed with the driving tooth 53, the second driving device 52 drives the driving tooth 53 to rotate, and the driving tooth 53 is meshed with different tooth grooves 511, thereby driving the moving rod 51 to move horizontally along its own axis. The corresponding driving teeth 53 drive the corresponding moving rod 51 to move, and the two moving rods 51 move toward each other and tightly clamp the bottle body of the inhalation medication device. When there is no need to rotate the rotating base 101, the two moving rods 51 can only play a role in straightening the bottle body.

[0052] As an alternative embodiment, see Figure 6 As shown, the shell includes a positioning inner shell 111, the inner contour of the positioning inner shell 111 matches the outer contour of the bottle body of the inhalation medication device, thereby positioning the bottle body; a sleeve 112 is provided on the side wall of the positioning inner shell 111, both ends of the sleeve 112 are open, and the sleeve 112 is connected to the inner cavity of the positioning inner shell 111, and the moving rod 51 can extend into the sleeve 112 and abut against the bottle body.

[0053] Since the inner contour of the positioning inner shell 111 matches the outer contour of the bottle body of the inhalation medication device, when the inhalation medication device is inserted into the positioning inner shell 111 of the shell, the positioning inner shell 111 is positioned with the bottle body and the bottle body does not shake. When the moving rod 51 moves, it is aligned with the sleeve 112, and the moving rod 51 extends into the sleeve 112 and tightly abuts against the bottle body. With this arrangement, the moving rod 51 realizes the positioning of the positioning inner shell 111 and the bottle body. The positioning inner shell 111 can limit the position of the bottle body and will not affect the clamping mechanism to clamp the bottle body.

[0054] As an alternative embodiment, see Figure 2 and Figure 3 As shown, the shell includes an upper shell 1, a lower shell 12 and a dust cover 2, wherein: the upper shell 1 includes a positioning inner shell 111, the inner contour of the positioning inner shell 111 matches the outer contour of the bottle body of the inhalation medication device, thereby positioning the bottle body; the top of the upper shell 1 is provided with an opening for the suction nozzle of the inhalation medication device to extend out; the driving mechanism and the fixing seat 3 are located in the lower shell 12, and the upper shell 1 is detachably fixedly connected to the lower shell 12; the dust cover 2 covers the outside of the upper shell 1 and is detachably connected to the lower shell 12.

[0055] The dust cover 2 is arranged outside the upper shell 1, and the mouthpiece is covered therein to prevent dust. When in use, the upper shell 1 can be disassembled to separate the inhalation medication device and the upper shell 1 from the lower shell 12, and then the inhalation medication device can be separated from the upper shell 1 to achieve replacement of the inhalation medication device.

[0056] The positioning inner shell 111 is a part of the upper shell 1, and serves as the inner shell of the upper shell 1. When the upper shell 1 is disassembled from the inhalation medication device, the second driving device 52 drives the moving rod 51 to move through the driving gear 53, and the two moving rods 51 are separated from each other. The moving rod 51 no longer clamps the bottle body, and the bottle body can be taken out of the positioning inner shell 111. After replacing a new inhalation medication device or refilling the inhalation medication device, it can be reinstalled into the positioning inner shell 111. At this time, the moving rod 51 can slightly contact the bottle body without being tightly pressed, and only plays the role of limiting and straightening.

[0057] This embodiment provides a locking and positioning implementation of the upper shell 1 and the lower shell 12, which can lock the upper shell 1 and the lower shell 12. As an optional implementation, see Figure 4 As shown, the upper shell 1 is provided with an insertion portion 6, and a locking hole 61 is provided on the insertion portion 6; a locking member 7 is provided in the lower shell 12, and the locking member 7 is movably provided; after the upper shell 1 and the lower shell 12 are aligned, the insertion portion 6 passes through the through hole of the lower shell 12 and extends into the lower shell 12, and the locking member 7 moves and passes through the locking hole 61, thereby locking the upper shell 1 and the lower shell 12. Among them, the insertion portion 6 is a rod body structure, and the rod body structure can pass through the through hole in the lower shell 12 to achieve initial positioning.

[0058] After the inhalation medication device is installed in the upper shell 1, the upper shell 1 is aligned with the lower shell 12, see Figure 4 As shown, after the upper shell 1 and the lower shell 12 are aligned, the insertion portion 6 passes through the through hole of the lower shell 12 and extends into the lower shell 12, and the locking member 7 moves and passes through the locking hole 61, thereby locking the upper shell 1 and the lower shell 12. When the locking member 7 passes through the locking hole 61 to lock the upper shell 1 and the lower shell 12, the rotating base 101 of the inhalation medication device extends into the fixing seat 3 and engages with the fixing seat 3.

[0059] As an alternative embodiment, see Figure 4 As shown, the medicine applying device also includes a third driving device 8, the output end of the third driving device 8 is fixedly connected to the locking member 7, and is used to drive the locking member 7 to move horizontally; the third driving device 8 can be an electric push rod or a telescopic cylinder, an electric cylinder, etc., and the telescopic end of the third driving device 8 is fixedly connected to the locking member, driving the locking member 7 to move and pass through the lock hole 61.

[0060] In order to facilitate the purpose of automation, the medication device of this embodiment also includes a control unit. A contact switch 9 is arranged on the base. The contact switch 9 is located on the moving path of the insertion part 6. The control unit is electrically connected to the contact switch 9 and the third drive device 8, and is used to control the third drive device 8 to operate when the insertion part 6 contacts the contact switch 9, thereby locking the insertion part 6.

[0061] After the upper shell 1 and the lower shell 12 are aligned, the insertion part 6 extends into the lower shell 12 through the through hole of the lower shell 12, and the bottom end of the insertion part 6 contacts the contact switch 9. The contact switch 9 sends a signal to the control unit, and the control unit controls the third drive device 8 to operate, so that the locking member 7 is inserted into the lock hole 61 to lock the upper shell 1 and the lower shell 12.

[0062] See also Figure 3 As shown, a transparent window 11 is provided on the shell, which is convenient for the user to observe the drug quantity indicating dial on the inhalation medication device (such as the inhalation medication device 100), so that the user can understand the remaining drug quantity.

[0063] A voice module and a button module can also be set in the shell, and the voice module and the button module are electrically connected to the control unit. When the upper shell 1 and the lower shell 12 are assembled together, the metal probes of the upper shell 1 and the lower shell 12 are docked, and the control unit detects that the upper shell 1 and the lower shell 12 are buckled, indicating that the user has replaced the new medicine. At this time, the voice will remind the user whether the new medicine has been replaced. If it has been replaced, please press the confirmation button. At this time, the device will re-record the number of medications; if there is no need to replace a new one, select "No", and the device will continue to record the previous number of medications; but when the number of medications reaches the upper limit of the product's dosage, the user will be reminded by voice to change the new medicine. When changing to a new medicine, enter the dosage of the new medicine on the screen according to the voice prompt, and the device will automatically count the medication. When the user takes the medicine, he can press the medication button on the screen. The device will clamp the bottle tightly through the clamping mechanism of the upper shell 1. The first driving device 41 in the lower shell 12 drives the fixing seat 3 to drive the inhalation medication device (such as the protection device 100) to rotate the rotating base 101 left and right. After the medication is applied, the user will be reminded to inhale the medicine in time and the remaining amount of medicine will be reminded.
