Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an oral drug delivery device. Background Technology

[0002] The oral cavity refers to the cavity inside the mouth, which consists of the lips, cheeks, hard palate, soft palate, etc. The oral cavity contains organs such as teeth, tongue, and salivary glands, and oral administration is a treatment method.

[0003] Currently, when treating patients' oral cavity, it is usually necessary to first examine the patient's oral cavity before applying medication using a handheld oral medication delivery device. However, existing oral medication delivery devices can only store one type of medication. When faced with different patient needs, medical staff cannot quickly switch between different medications for medication application, resulting in poor flexibility. Furthermore, after examining the patient's wound, medical staff need to change and retrieve the medication delivery device again for medication application. The lack of an integrated setup of examination and medication delivery devices makes the process inefficient.

[0004] To address the aforementioned problems, the inventors have proposed an oral drug delivery device. Summary of the Invention

A camera device body 39 is fixedly installed in the middle of the bottom end of the fixed box 33.

[0034] By adopting the above technical solution, the lower camera device body 39 can be extended, retracted, and cleaned.

[0035] The drive assembly includes a first motor 22, the top of which is fixedly mounted on the inner upper surface of the housing 1, and the top of one side of the rotating block 222 is fixedly mounted on the drive end of the first motor 22.

[0036] By adopting the above technical solution, the first motor 22 can drive the rotating block 222 and the second drive block 221 to rotate.

[0037] The connecting assembly includes a drive belt 251, with one side of the drive belt 251 fixedly installed at the center of the drive end of the second motor 25, and the other end of the drive belt 251 away from the second motor 25 fixedly installed at the center of one side of the first gear 252.

[0038] By adopting the above technical solution, when the second motor 25 drives the first gear 252 on the upper part of the fixed block 24 to rotate, it can drive the transmission belt 251 to rotate. Through the transmission of the transmission belt 251, the first gear 252 set on the lower part of the fixed block 24 can be driven to rotate.

[0039] Each of the multiple first toothed plates 26 has a first slider 261 fixedly installed on one side, and each of the multiple first sliders 261 is slidably locked onto one side of the fixed block 24.

[0040] By adopting the above technical solution, the first toothed plate 26 becomes more stable when moving.

[0041] Each of the multiple sets of fixing blocks 24 has four first limiting rods 271 fixedly installed on one side, and each of the multiple clamping blocks 27 has one side slidably installed on the outer surface of the first limiting rods 271.

[0042] By adopting the above technical solution, when the first toothed plate 26 moves and drives the clamping block 27 to move, the first limiting rod 271 limits the clamping block 27, making the movement of the clamping block 27 more stable.

[0044] By adopting the above technical solution, the third fixing rod 34 can be prevented from rotating under the limiting position of the first sliding groove 342 on the second slider 341, thus preventing the fixing box 33 from rotating.

[0045] A fixing plate 331 is fixedly installed on the upper inner surface of the fixing box 33, and the third rotating shaft 351 slides through the lower part of the fixing plate 331 on the side near the second gear 371.

[0046] By adopting the above technical solution, the rotation of the third rotating shaft 351 is made more stable.

[0047] A limiting hole 411 is provided in the middle of one side of the transparent baffle 4, and the middle part of the limiting pin 41 is slidably inserted into the limiting hole 411.

[0048] By adopting the above technical solution, the limiting pin 41 can be inserted into the limiting hole 411, thereby facilitating the limiting and fixing of the transparent baffle 4.

[0049] A telescopic rod 43 is fixedly installed on the side of the housing 1 near the transparent baffle 4, and the top end of the telescopic rod 43 is fixedly installed on the bottom end of the limiting pin 41.

[0050] By adopting the above technical solution, the limiting pin 41 becomes more stable when it extends and retracts to limit the transparent baffle 4.

[0051] Working principle: During use, starting the first motor 22 drives the rotating block 222 to rotate, which in turn drives the second drive block 221 to rotate. Since the first drive block 211 has several first grooves 212 in its center, when the rotating block 222 rotates, it moves within the first grooves 212, causing the first drive block 211 to rotate, thus driving the rotating disk 21 to rotate. When the rotating block 222 moves away from the first groove 212, one side of the second drive block 221 slides and is limited to one side of the second groove 213, ensuring that the first drive block 211 does not rotate. Through their cooperation, the rotating disk 21 rotates intermittently, thereby driving the first fixed rod 23 to rotate, which in turn drives the fixed block 24. The first rotating shaft 2 has a first limiting groove 242 on its outer surface. The first limiting block 241, which is fixedly installed on one side of the fixed block 24, is slidably installed inside the first limiting groove 242. When the fixed block 24 rotates, it will be limited by the first limiting groove 242, so that the fixed block 24 can move up and down. When the fixed block 24 reaches the side where the first electric push rod 11 is installed, the fixed block 24 is at its lowest point. At this time, the lower part of the medicine reservoir 28 on one side of the fixed block 24 is located on the lower outer side of the housing 1, which facilitates the application of medicine to the patient's wound. Driven by the first electric push rod 11, one end of the medicine reservoir 28 is pushed, thereby pushing the medicine out from the inside of the medicine reservoir 28, and then applying medicine to the patient's oral wound.

[0052] Driven by the second motor 25, the first gear 252 rotates, causing the two diagonally distributed first toothed plates 26 to move relative to each other. Simultaneously, driven by the transmission belt 251, the first gear 252 mounted on the lower part of the fixing block 24 rotates, causing the two diagonally distributed first toothed plates 26 to move relative to each other. Thus, by placing the medicine reservoir 28 in the middle of the clamping block 27, the relative movement of the first toothed plates 26 causes the clamping block 27 to move relative to each other, thereby clamping and fixing the medicine reservoir 28. When the medicine reservoir 28 rotates under the drive of the first motor 22, the usage of the medicine inside the medicine reservoir 28 can be observed through the transparent baffle 4. When the medicine inside the medicine reservoir 28 is used up, by pulling down the limiting pin 41, the limiting pin 41 moves away from the inside of the limiting hole 411, thereby pulling the transparent baffle 4 to move to one side of the housing 1, so that the housing 1 can be opened and the medicine reservoir 28 inside can be replaced. The medicine reservoir 28 is a disposable product, which makes it convenient for its use.

[0053] During oral cavity observation, the second electric actuator 31 drives the second rotating shaft 32 forward. Since a second limiting block 321 is mounted on one side of the second rotating shaft 32 and slidably installed inside the threaded groove 322, the second rotating shaft 32 rotates when it moves downwards. This causes the first crown gear 323 to rotate, which in turn rotates the second crown gear 35 meshing with it. This, in turn, drives the third rotating shaft 351 to rotate, causing the connecting rod 36, which is slidably locked in the middle of the sliding block 361, to rotate. Under the limitation of the second limiting rod 332, the second toothed plate 37 and the sliding block 361 are... Driven by the connecting rod 36, block 361 moves back and forth on the outer surface of the second limiting rod 332, thereby driving the second gear 371 to rotate forward and backward, which in turn drives the cleaning plate 38 to swing forward and backward. Through the forward and backward swing of the cleaning plate 38, the camera device body 39 installed at the lower part of the fixing box 33 can be cleaned, avoiding the influence of water vapor, which would make it unclear when the camera device body 39 transmits the internal oral cavity condition to the computer monitor, affecting the medical staff to find the wound condition inside the patient's oral cavity. After the observation is completed, the camera device body 39 can be retracted backward by the drive of the second electric push rod 31, so that the wound can be treated with medicine through the medicine reservoir 28.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
