Description

Technical Field

[0001] This utility model relates to the field of veterinary equipment technology, and in particular to a drug delivery device that facilitates opening expansion. Background Technology

[0002] Veterinary medication dispensers are specialized tools used in animal medical care, primarily for drug injection, fluid supplement delivery, and oral administration to improve treatment efficiency and safety. To optimize animal productivity, it is often necessary to feed or inject medications; injected medications are administered directly into the animal's body via syringe.

[0003] Administering liquid medication is quite difficult for animal owners. First, it requires manually opening the animal's mouth, which poses a risk of injury to the owner. Second, the animal may resist when the liquid medication is put into its mouth, resulting in incomplete administration, wasted medication, and reduced effectiveness.

[0004] Therefore, to address the above problems, a drug delivery device that facilitates opening expansion is proposed to solve these problems. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by developing a drug delivery device that facilitates mouth expansion. This invention has a simple structure, avoids human injury during drug administration, and facilitates the delivery of medication into the animal's mouth, reducing drug waste.

[0006] The technical solution to the technical problem solved by this utility model is as follows: This utility model provides a drug delivery device that facilitates opening expansion, including an injection tube, an expansion arm one, an expansion arm two, a support frame, a screw, and a connecting rod. The support frame includes a connecting arm one, a mounting block, and a connecting arm two connected in sequence. The injection tube is movably mounted on the mounting block, and a screw is threaded horizontally inside the mounting block. Both connecting arm one and connecting arm two are at an obtuse angle to the mounting block. The ends of connecting arm one and connecting arm two away from the mounting block are respectively rotatably set with expansion arm one and expansion arm two. Each of expansion arm one and expansion arm two is rotatably connected to a connecting rod in the middle. The end of the connecting rod away from expansion arm one or expansion arm two is hinged to the front end of the screw.

[0007] As an optimization, both the first and second expansion arms are provided with arc-shaped bends at the ends away from the support frame, and the opening directions of the two arc-shaped bends are far apart from each other.

[0008] As an optimization, anti-slip strips are installed inside the curved section, and the surface of the anti-slip strips is serrated.

[0009] As an optimization, a mounting plate is also included. The bottom of the mounting plate is provided with a groove, and the mounting plate is locked onto the top of the mounting block through the groove. A mounting seat is slidably mounted on the mounting plate. A limiting plate is provided at the end of the mounting plate to prevent the mounting seat from falling out. The mounting seat has a mounting hole for mounting the injection tube in the horizontal direction.

[0010] As an optimization, a connecting plate is horizontally installed at the front end of the screw, and a connecting rod is rotatably connected to each end of the connecting plate.

[0011] As an optimization, a rotating handle is provided at the end of the screw away from the connecting plate, and an anti-slip sleeve is fitted over the rotating handle.

[0012] As an optimization, a handle is vertically installed at the bottom of the mounting block, and a pad is installed at the front end of the mounting block. The pad has an arc-shaped cross-section and is located below the screw.

[0013] The effects provided in the utility model description are merely those of the embodiments, and not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects: 1. This medication applicator has a simple structure, making it easy to open the animal's mouth when administering medication, eliminating the need for manual prying and avoiding injury to the human during administration. At the same time, this applicator facilitates the delivery of medication into the animal's mouth, reducing medication waste. 2. Place the medication applicator in the animal's mouth, rotate the handle, and the screw will move forward along the mounting block, causing the connecting plate to move forward. This will cause connecting arms one and two to rotate around their connection with the connecting plate, pushing expanding arms one and two to move away from each other, thus opening the animal's mouth. Install the injection tube on the mounting base, which is then installed on the mounting plate. Secure the mounting plate to the mounting block, and then push the syringe to administer the medication. The operation is simple, medication administration is convenient, and medication waste is avoided. Attached Figure Description

The support frame 4 includes a connecting arm 41, a mounting block 42, and a connecting arm 43 connected in sequence. The injection tube 1 is movably mounted on the mounting block 42, and the screw 5 is threaded horizontally inside the mounting block 42. The connecting arms 41 and 43 form obtuse angles with the mounting block 42. The expansion arms 2 and 3 are rotatably mounted on the ends of the connecting arms 41 and 43 away from the mounting block 42, respectively. A connecting rod 6 is rotatably connected to the middle of each of the expansion arms 2 and 3. The end of the connecting rod 6 away from the expansion arm 2 or 3 is hinged to the front end of the screw 5. This drug delivery device has a simple structure, making it easy to open the animal's mouth when administering medication, eliminating the need for manual prying and avoiding injury to the human during administration. Furthermore, this drug delivery device facilitates the delivery of medication into the animal's mouth, reducing medication waste.

[0019] In this embodiment, both the first expansion arm 2 and the second expansion arm 3 have an arc-shaped bend 7 at the end away from the support frame 4, and the opening directions of the two arc-shaped bends 7 are far apart from each other. The arc-shaped bends facilitate opening the animal's mouth.

[0020] An anti-slip strip 71 is provided inside the curved section 7. The surface of the anti-slip strip 71 is serrated. The anti-slip strip 71 increases the friction when the animal's mouth is opened, preventing slippage.

[0021] In this embodiment, a mounting plate 8 is also included. A groove 81 is provided at the bottom of the mounting plate 8, and the mounting plate 8 is secured to the top of the mounting block 42 via the groove 81. A mounting seat 82 is slidably mounted on the mounting plate 8. A limiting plate 83 is provided at the end of the mounting plate 8 to prevent the mounting seat 82 from dislodging. The mounting seat 82 has a mounting hole 84 in the horizontal direction for mounting the injection tube 1. In use, the injection tube 1 is passed through the mounting hole 84, allowing it to be mounted on the mounting seat 82. Then, the mounting seat 82 is mounted on the mounting plate 8 at the limiting plate 83, and finally, the mounting plate 8 is secured to the top of the mounting block 42 via the groove 81.

[0022] In this embodiment, a connecting plate 9 is horizontally arranged at the front end of the screw 5, and a connecting rod 6 is rotatably connected to each end of the connecting plate 9.

[0023] A rotating handle 10 is provided at the end of the screw 5 away from the connecting plate 9, and an anti-slip sleeve 101 is fitted on the outside of the rotating handle 10.

[0024] A handle 421 is vertically mounted at the bottom of the mounting block 42, and a pad 422 is mounted at the front end of the mounting block 42. The pad 422 has an arc-shaped cross-section and is located below the screw 5. The pad 422 is used to press down on the animal's tongue to increase the feeding space, and the handle 421 facilitates holding the entire device.

[0025] How to use: In use, the operator first holds the handle 421 with one hand and places the medication dispenser into the animal's mouth, pressing down the animal's tongue with the pad 422. With the other hand, the operator rotates the handle 10, causing the screw 5 to move forward along the mounting block 42, which in turn moves the connecting plate 9 forward. This causes the connecting arm 1 41 and connecting arm 2 43 to rotate around their connection with the connecting plate 9, pushing the expansion arm 1 2 and expansion arm 2 3 to move away from each other, thus opening the animal's mouth. At this point, the injection tube 1 is installed on the mounting base 82, and the mounting base 82 is installed on the mounting plate 8. The mounting plate 8 is then secured to the mounting block 42. Then, the syringe 1 is pushed to administer the medication. Since the syringe 1 is pushed into the animal's mouth, medication waste can be effectively avoided.

[0026] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
