Description

Technical Field

[0001] The utility model relates to the technical field of intravenous infusion, in particular to a rabbit ear vein infusion fixing device. Background Art

[0002] Intravenous infusion is a method of injecting large amounts of sterile liquids, electrolytes, and drugs into the body through veins by utilizing the principles of atmospheric pressure and liquid static pressure. The injection of large amounts of liquids, electrolytes, or blood into veins is called intravenous infusion. Due to the differences in the injection site and the infusion, it can be divided into peripheral intravenous infusion, central venous infusion, highly nutritious infusion (TPN), and blood transfusion. In animal experimental teaching in medical schools, rabbits are often used instead of simulating human bodies for experimental observation or scientific research. To facilitate injection and blood collection, the rabbit's ear vein is often used for intravenous infusion.

[0003] Usually when conducting animal experiments, it is difficult to fit the wing of the injection needle to the ear edge because the rabbit's ear edge tissue is relatively soft and hair grows on the ear edge. When the rabbit shakes its ear, the injection needle is likely to fall off, causing the experiment to go wrong. Therefore, a rabbit ear edge intravenous infusion fixing device is proposed to solve the above problems. Utility Model Content

[0025] exist Figure 2 In the method, the body and limbs of the rabbit are fixed by the first elastic band 3 and the second elastic band 4 to prevent the rabbit from moving around and causing the needle to fall off.

[0026] exist Figure 2 In the embodiment, the stretching force of the spring 503 drives the movable plate 504 to clamp the rabbit ear, because the area of ​​the movable plate 504 can press the entire rabbit ear, and the rabbit ear will not be separated from the first clamping plate 501 and the second clamping plate 502.

[0027] exist Figure 2 In the embodiment, the wing piece is fixed by the card 507, which can well solve the problem that the wing piece and the ear edge are difficult to fix.

[0028] In summary, the rabbit ear edge intravenous infusion fixing device places the rabbit in a fixing box 1, fixes the rabbit's body with a first elastic band 3, fixes the rabbit's limbs with a second elastic band 4, passes the two ears of the rabbit through the partition 2 and reaches the top of the first splint 501, limits the ear part by fitting the first splint 501 with the second splint 502, and fixes the ear with a movable plate 504 to prevent the ear from moving around and causing unstable intravenous injection.

[0029] In addition, the rabbit ear edge intravenous infusion fixing device is configured to fix the injection head by engaging the wing on the outside of the injection head with the card 507, and then fixing the wing and the card 507 with medical tape.
