Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical device equipment, in particular to an animal ear marginal vein injection fixing clip, and more particularly to an ear marginal vein injection fixing device for experimental rabbits. Background Art
[0002] As one of the most commonly used experimental animals, rabbits are widely used in various experiments such as medical physiology, pharmacy, and biology. Ear marginal vein injection is the most basic operation in rabbit experiments. The current mainstream method of ear marginal vein injection is that the operator fixes the rabbit ear with one hand and holds the needle with the other hand for intravenous injection, which is difficult for beginners. There are mainly the following five difficulties: 1. The ear marginal vein of the rabbit is relatively thin and difficult to locate, and it is even more difficult to accurately puncture when operating alone with one hand; 2. When the operation is not skilled, such as incorrect hand posture, it will increase the difficulty of successful drug injection or blood drawing; 3. The needle insertion angle is not easy to control. If the angle is incorrect or too much force is applied, it will pierce through the rabbit ear and even stab the operator; 4. Poor fixation is likely to cause the rabbit to break free, resulting in the needle coming out of the rabbit's vein; 5. If the needle insertion fails multiple times, it will not only affect the experimental process but also not meet the requirements of animal welfare. Therefore, researching and developing an animal ear marginal vein injection fixing device with a simple structure, quick fixation, convenient needle insertion, and low cost is the key to solving the above problems.
[0003] The Chinese utility model patent specification CN 211094953 U discloses a simple fixing device for rabbit ear marginal vein injection, which can fix and stretch the rabbit ear through two ear clips at the proximal end and the distal end. The Chinese utility model patent specification CN 209629902 U discloses a rabbit ear marginal vein injection and administration device, which can fix rabbit ears of different lengths and the syringe temporarily staying on the rabbit ear and adjust the tilt angle of the rabbit ear. The Chinese utility model patent specification CN203555857 U discloses an air injection device for rabbit ear marginal vein in anatomical and physiological experiments. This air injection device for rabbit ear marginal vein in anatomical and physiological experiments uses the bent head of the splint to lift and bend the rabbit ear margin to facilitate inserting the syringe needle into the rabbit ear marginal vein. The Chinese utility model patent specification CN212913473U discloses a combined device of a rabbit ear marginal vein injection needle and an ear clip, which connects the injection needle and the ear clip through a connecting chain. However, these devices do not solve the problems of difficult observation of animal ear marginal veins and difficult needle insertion, and the device operation is complex and not suitable for wide promotion and use in experimental teaching.

The upper clamping plate 1 and the lower clamping plate 2 are connected through the connecting structure 3. There is a torsion spring 4 at the connection of the upper clamping plate 1 and the lower clamping plate 2, so that the clamping parts of the upper clamping plate 1 and the lower clamping plate 2 maintain a clamped state without external force. The hand-held part and the clamping part of the upper clamping plate 1 are in the same plane, and there are 2 symmetrical convex grooves 9 on the clamping part for the animal blood vessels to pass through.

There is an angle between the hand-held part and the clamping part of the lower clamping plate 2. When the hand-held parts of the upper clamping plate 1 and the lower clamping plate 2 are forced to close, the space between the clamping part of the upper clamping plate 1 and the light-transmitting plate 8 can be opened, so that there is enough space for the animal ear edge to be placed between the clamping part of the upper clamping plate 1 and the light-transmitting plate 8;
[0027] In some embodiments, it further includes a blood-blocking wedge 10. The blood-blocking wedge 10 is wedge-shaped, and its shape and size are adapted to the convex groove 9 of the upper clamping plate 1.
[0028] Preferably, the upper clamping plate 1 and the lower clamping plate 2 are made of hard materials such as metal and hard plastic, with relatively light weight and the materials are not easily deformed, which can effectively clamp the animal ear edge.

[0030] Preferably, a gasket 5 is provided at the contact part between the upper clamping plate 1 and the light-transmitting plate 8, which increases the comfort of the animal ear edge while ensuring the clamping effect on the animal ear edge.
[0031] Preferably, the LED light strips 7 are arranged in 2 to 4 rows of lamp beads to provide a larger backlight area.
[0032] Preferably, the battery box 6 is powered by button batteries, which effectively reduces the volume and weight of the present utility model while ensuring the power supply of the LED light strips 7.
[0033] Preferably, the blood-blocking wedge 10 is made of rubber material, and the blood-blocking effect is better.
[0034] Embodiment 2
[0035] When performing auricular marginal vein injection on an animal, first flatten the auricular margin of the animal, hold the hand-held parts of the upper splint 1 and the lower splint 2, so that there is enough space between the clamping part of the upper splint 1 and the light-transmitting plate 8 to place the auricular margin of the animal, and release the hand-held parts of the upper splint 1 and the lower splint 2, so that the auricular margin of the animal is clamped between the clamping part of the upper splint 1 and the light-transmitting plate 8; secondly, turn on the switch of the battery box 6 to make the LED light strip 7 emit light, providing backlight for the auricular marginal vein injection operation of the animal, making the auricular marginal vein clearly visible; then insert the blood-blocking wedge 10 between the auricular margin of the animal and the light-transmitting plate 8 to prevent the auricular marginal vein of the animal from flowing back, making the blood vessels full and facilitating needle insertion, and remove the blood-blocking wedge 10 after needle insertion; after the auricular marginal vein injection is completed, hold the hand-held parts of the upper splint 1 and the lower splint 2 to open the space between the clamping part of the upper splint 1 and the light-transmitting plate 8, and then remove the present utility model from the auricular margin of the animal.
[0036] Certainly, the connection structure 3 between the upper splint 1 and the lower splint 2 of the present utility model is not limited to the cross-bar connection. On the premise of ensuring the clamping effect of the auricular margin of the animal by the upper splint 1 and the lower splint 2, other structures can also be adopted. Similarly, the shape of the convex groove 9 for the auricular marginal blood vessels of the upper splint 1 is not limited to the arc shape, and can also be in the shape of a triangle, a trapezoid, a semi-elliptical shape or other applicable shapes.
