Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry and veterinary equipment, in particular to an oral splint for animal husbandry. Background Art

[0002] The primary function of a livestock oral speculum is to open the animal's mouth, allowing veterinarians to clearly visualize the internal structures and pathological conditions. It is widely used in oral care for a variety of animals, including examinations of teeth, oral mucosa, and throat, as well as for medication administration and injections.

[0003] Application No. 2023226596805 discloses a mouth-opening device for animal husbandry and veterinary medicine, belonging to the technical field of animal husbandry medical instruments. The device comprises a fixed bracket and a rod connected to the fixed bracket and movable relative to the fixed bracket. The device further comprises a pair of first and second opening plates disposed at one end of the rod, and a first connecting member rotatably connected between the first opening plate and the rod, and a second connecting member rotatably connected between the second opening plate and the rod. When the rod moves relative to the fixed bracket, the first and second opening plates can move between an open position away from each other and a closed position close to each other. Using a mechanical device to open the animal's mouth eliminates the need for consuming a large amount of power, reduces labor intensity, and improves work efficiency. It also avoids the possibility of the veterinarian's palm being bitten due to direct contact with the animal's mouth with his hands.

[0004] The above technical solution can easily open the animal's mouth, but it still has the following disadvantages: 1. The operation is complicated, and both hands are required to operate the opening device at the same time to open the animal's mouth; 2. The contact area between the opening plate and the animal's teeth is small, and the force acting on the animal's teeth is large, which can easily cause the animal to panic, break free from the opener, and easily bite the veterinarian; 3. When administering medicine to the animal, the intubation tube lacks a fixing tool and is easy to fall off. Utility Model Content

[0005] The utility model provides an oral splint for animal husbandry, which solves the problems of existing oral splints for animal husbandry being complicated to operate, having a small contact surface between the splint plate and the animal, easily causing the animal to panic and break free from the splint, and lacking fixing tools for intubation when administering medicine to the animal.

[0006] The technical solution of the utility model is: a mouth opener for livestock, comprising a screw rod, a guide column, a reducer, a motor, a battery, a control chip, a middle frame, an upper cover, a lower cover, a handle, a slider, a brace, a switch, and a reversing switch. The middle frame, the upper cover, and the lower cover are detachably connected. A guide column is provided in the middle frame, and the two ends of the guide column are connected to the upper cover and the lower cover. A screw rod is provided in the middle frame, and the two ends of the screw rod are rotatably connected to the upper cover and the lower cover. The end of the screw rod is connected to the output shaft of the reducer, and the input shaft of the reducer is connected to the output shaft of the motor. The slider moves along the screw rod and the guide column. The front end of the middle frame is slotted, and the rear end is provided with a handle. The inside of the handle is provided with a switch, and the outside of the handle is provided with a reversing switch. The lower cover is detachably connected to the brace, and the middle part of the slider is detachably linked to the brace. The lower cover contains a battery, and the motor, battery, control chip, switch, and reversing switch are electrically connected.

[0007] Preferably, an LED bulb is provided at the front end of the middle frame.

[0008] Preferably, one side of the middle frame is rotatably connected to a tube fixing plate, and the tube fixing plate is provided with a tube hole.

[0009] Preferably, the middle frame is made of aluminum alloy.

[0010] Preferably, the insertion hole is made of silicone material, with a central opening and a groove from the center to the outer edge.

[0011] Preferably, the upper cover and the lower cover are made of engineering plastics.

[0012] Preferably, the braces are U-shaped.

[0013] Preferably, the braces are made of engineering plastics, and the upper end surface is paved with a rubber pad.

[0014] Preferably, the braces are threadedly connected to the lower cover and the slider.

[0015] Preferably, the battery is a lithium battery.

[0016] Principle of the utility model: In order to solve the problem that the existing oral retractors are not convenient to operate, the utility model adopts a screw to drive the braces to move up and down, thereby opening the animal's mouth, saving time and effort, and can be operated with one hand, improving medical efficiency and alleviating animal pain. The screw is driven by a reducer and an electric motor, which converts high speed and low torque into low speed and high torque, which can easily open the animal's mouth. There is a switch on the inside of the grip and a reversing switch on the outside, which is convenient for the user to control the direction of the motor to realize the opening and closing of the braces. The braces can be manufactured in several groups according to the gum size of different animals to match different The invention can fit the animal's gums to the greatest extent, reduce the animal's discomfort, and avoid the user being bitten due to the animal's panic. The utility model is rotatably connected to the side of the middle frame with an intubation fixing plate, and the intubation fixing plate is provided with an intubation hole. The intubation hole is made of silicone material, with a hole in the center and grooves from the center to the outer edge. With such a structure, when injecting medicine, intubations of different diameters can pass through the intubation hole. Since the friction between the edge of the intubation hole and the intubation is large, the intubation is not easy to fall off, which can ensure smooth injection of medicine and facilitate the user to simultaneously open the animal's mouth and inject medicine.

[0017] The beneficial effects of the utility model are as follows: the oral retractor for livestock is easy and quick to operate, has excellent ergonomics, can shorten the medical operation time, reduce the discomfort of animals, and prevent users from being bitten by animals.
