Description

Technical Field

[0001] This utility model belongs to the technical field of animal tracheal infusion devices, and specifically relates to a visual animal tracheal infusion device. Background Technology

[0002] Intratracheal instillation in animals is a method of drug delivery, inducing the administration of test samples such as drugs, chemicals, and environmental pollutants into the lungs through the trachea. It is widely used in research fields such as inhaled drug development, chemical safety testing, and environmental health. Typically, tracheal instillation in animals involves endotracheal intubation to deliver the test sample. However, due to the narrow trachea of ​​experimental animals, this method suffers from low intubation success rates, high animal mortality rates, and requires a high level of expertise. It is difficult to achieve good reproducibility and accurate drug delivery.

[0003] To reduce the difficulty and complexity of endotracheal perfusion procedures in animals and improve the repeatability and accuracy of drug administration, researchers in the field have disclosed a visual operating device that allows for endotracheal perfusion by observing the animal's internal condition using an endoscope. Test reports of the device demonstrate that it can rapidly, stably, accurately, and successfully perfuse test samples into the lungs.

[0004] Existing technologies, such as those disclosed in Korean Patent Publication Nos. KR20120050802A and KR101259154B1, disclose a device that features an added camera module, assisted by an electric push rod to achieve visualized drug delivery. This improves the efficiency of animal drug delivery and addresses inaccuracies, but the device also has limitations. The device disclosed in the Korean patent will be referred to as this handheld device. Limitation 1: The front-end camera module of this handheld device is non-replaceable, and the instrument channel reserved in the module is small, limiting the size of the drug delivery tube that can be loaded. These limitations often restrict the device to internal drug delivery in small animals. Furthermore, the camera module is generally a delicate and easily damaged component with a short lifespan, further limiting the lifespan of this handheld device. Limitation 2: The syringe assembly of this handheld device is fixed, and the distance the drug delivery tube extends beyond the camera module is pre-cut according to drug delivery requirements, resulting in a fixed length of the extended drug delivery tube. This leads to variations in cannulation positions during experiments due to individual differences among animals, necessitating adjustments to the cannulation location. This method is prone to reducing efficiency.

[0005] To address the shortcomings of the existing technology, this utility model discloses a visual animal tracheal drug delivery device.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

The camera module 1 is detachably connected to the syringe module 2, and the syringe module 2 is mounted on the telescopic module 3. The telescopic module 3 has the function of pushing the syringe module 2 to move linearly. The handle 4 is connected to the telescopic module 3, and the control box 5 is connected to the handle 4.

[0021] In this embodiment, as a specific solution, the syringe module 2 includes a housing 21 disposed on the telescopic module 3 and an injection mechanism disposed on the housing 21. The injection mechanism is specifically a syringe 22, which includes a syringe body 221 and a syringe plunger 222. The housing 21 is provided with a drive mechanism 23 for driving the syringe plunger 222 to move linearly. The syringe body 221 is also provided with a drug delivery tube 24, and the camera module 1 is detachably connected to the drug delivery tube 24.

[0022] In this embodiment, as a specific solution, the syringe 22 is detachably mounted on the housing 21; more specifically, the housing 21 is also provided with an injection mechanism fixing seat, specifically a syringe fixing seat 211. The syringe fixing seat 211 and the housing 21 are an integral structure. The syringe body 221 is mounted on the syringe fixing seat 211 by a syringe clamp 212, and the syringe clamp 212 is fixed by a plug screw 213. The plug screw 213 can be removed from the syringe clamp 212 to adapt to syringes of different specifications.

[0023] In this embodiment, as a specific solution, the camera module 1 includes a bracket 11, a camera module 12, and a quick-change tongue clamp 13. The bracket 11 is mounted on the telescopic module 3, and the quick-change tongue clamp 13 is mounted on the bracket 11. The drug delivery tube 24 passes through the quick-change tongue clamp 13 and is connected to the camera module 12 through the quick-change tongue clamp 13.

[0024] In this embodiment, as a more specific solution, the bracket 11 is provided with a quick-change hole 111 and a fixing hole 112. The quick-change tongue clamp 13 is composed of a first plunger structure 131 and a second plunger structure 132. The first plunger structure 131 and the second plunger structure 132 are respectively inserted into the quick-change hole 111 from both sides. Both the first plunger structure 131 and the second plunger structure 132 have channels for accommodating the passage of the drug delivery tube 24. The channel of the second plunger structure 132 can also accommodate the camera module 12 at the same time. Furthermore, the diameter of the channel matches the camera module 12 and the drug delivery tube 24 to ensure that the camera module 12 will not loosen (i.e., the channel can hold the camera module 12 and the drug delivery tube 24 in place). The first plunger structure 131 and the second plunger structure 132 are locked in place by bolts or screws through the fixing hole 112. When the camera module 12 needs to be replaced, the bolts or screws are removed from the fixing hole 112, and the first plunger structure 131 and the second plunger structure 132 are removed from the quick-change hole 111 for replacement.

[0025] In this embodiment, as a specific solution, the drive mechanism 23 includes a lead screw motor 231, a guide rail 232, and a slider 233. The guide rail 232 is disposed inside the housing 21, and the slider 233 is disposed on the guide rail 232 and contacts the syringe plunger 222. The lead screw motor 231 is disposed inside the housing 21 and connected to the slider 233. When the lead screw motor 231 is working, it can push the slider 233 to move on the guide rail 232, thereby pushing the syringe plunger 222 to achieve injection.

[0026] In this embodiment, as a more specific solution, the slider 233 is also provided with a fine-tuning push block 234. The fine-tuning push block 234 contacts the syringe plunger 222. When it is not necessary to drive the lead screw motor 231, the fine-tuning push block 234 can achieve a small-distance pushing action. For example, when the power is insufficient, the motor fails, or other special circumstances occur, and it is inconvenient to stop the injection while it is in progress, the fine-tuning push block 234 can be turned to continue the injection. The fine-tuning push block 234 is similar to a bolt structure.

[0027] In this embodiment, as a specific solution, the telescopic module 3 includes a telescopic module housing 31, a telescopic lead screw motor 32 disposed within the telescopic module housing 31, and a telescopic guide rail 33. The outer shell 21 of the syringe module 2 is disposed on the telescopic module housing 31. The telescopic guide rail 33 is connected to the outer shell 21 of the syringe module 2. The telescopic lead screw motor 32 is connected to the outer shell 21 of the syringe module 2 via a connecting plate 34. The telescopic lead screw motor 32 drives the outer shell 21 of the syringe module 2 to slide along the telescopic guide rail 33. When the telescopic lead screw motor 32 is working, it pushes the outer shell 21 to move on the telescopic guide rail 33 through the connecting plate 34, thereby adjusting the position of the syringe module 2, that is, adjusting the drug delivery position. After reaching the drug delivery position, the syringe module 2 then operates to achieve injection.

[0028] In this embodiment, as a more specific solution, the telescopic module housing 31 is also provided with a sliding potentiometer 35, which is used to provide feedback on the position of the syringe module 2.

[0029] In this embodiment, as a specific solution, the telescopic module housing 31 is further provided with a control knob 36, which is electrically connected to the telescopic lead screw motor 32. The telescopic lead screw motor 32 is operated via the control knob 36, making it simple and easy to use.

[0030] In this embodiment, as a specific solution, the handle 4 is provided with a trigger button 41, which is electrically connected to the lead screw motor 231. The lead screw motor 231 can be controlled to work through the trigger button 41.

[0031] In this embodiment, as a specific solution, the control box 5 is equipped with a control board and a lithium battery.

[0032] In this embodiment, as a specific solution, the control box 5 is also provided with a display screen 51.

[0033] In this embodiment, as a specific solution, the telescopic module 2 is also provided with an indicator light 37.

[0034] The working principle of this utility model is as follows: After loading the syringe 22 with the experimental drug, place it on the syringe holder 211. The drug delivery tube 24 passes through the bracket 11 until it is exposed. Fix the syringe 22 with the syringe clamp 212 and the plug screw 213. Lift the handle 4 and align the drug delivery tube 24 with the animal's administration site. Based on the image fed back by the camera module 12, control the telescopic screw motor 32 to work through the control knob 36. The telescopic screw motor 32 pushes the outer shell 21 to move on the telescopic guide rail 33 through the connecting plate 34, thereby adjusting the position of the syringe module 2, that is, adjusting the administration position. After reaching the administration position, control the push screw motor 231 to work through the trigger button 41. The push screw motor 231 pushes the slider 233 to move on the guide rail 232, thereby pushing the syringe push rod 222 to achieve injection. During the injection process, the administration can be observed through the indicator light 37 to see if the administration is completed, and the administration information is displayed on the display screen 51.

[0035] The camera module of this utility model is detachably connected to the syringe module, which facilitates regular maintenance and replacement of vulnerable parts and avoids affecting the service life of the overall device due to local vulnerable parts. This invention can be adapted to syringes of different capacities, thus making it suitable for animal experiments of different sizes. By pushing the lead screw motor to make the syringe plunger move linearly, injection can be achieved, allowing for quantitative and rate-controlled drug administration and ensuring accuracy during the drug administration process. This invention controls the linear movement of the syringe module via a telescopic module, thereby controlling the linear movement of the drug delivery system. This makes it easier to address the different behaviors of animals during drug administration and also helps in situations where a single-round operation in an experiment requires simultaneous drug delivery to multiple target organs in the animal's body.
