Needle penetration guide device

Abstract

The invention discloses a needle penetration guide device. The guide device comprises a handle, a connecting rod and a puncture hook head, wherein one end of the connecting rod is connected with the handle and the other end of the connecting rod is connected with the puncture hook head; an included angle theta is formed between the puncture hook head and the connecting rod; and the puncture hook head is a cone with a sharp lower end and is provided with at least one notch. When injection is given to an animal or the blood of the animal is drawn, the puncture hook head of the guide device is first inserted into skin on a blood vessel, a small cut is slightly opened on the skin with the handle to make the blood vessel seen, and the needle is penetrated into the blood vessel along the notch of the puncture hook head, so that the blood is successfully drawn or the injection is successfully applied. The needle penetration guide device has the advantages of simple structure, convenient blood drawing or injection, high success rate and small cut.

Description

technical field [0001] The invention discloses an instrument for animal experiments and related occasions, in particular to an animal blood collection or injection needle insertion guiding auxiliary tool. Background technique [0002] In the field of animal experiments and animal husbandry and veterinary medicine, small animals are often injected with drugs and blood samples are taken. Because animals have thick fur or small blood vessels, it is difficult to find blood vessels. If a hand-held needle is directly inserted, the success rate is low, and it usually takes several times to complete. The needle is easily contaminated, and it is easy to cause animal phlebitis and periphlebitis. It does not meet the hygienic requirements, and the efficiency is low. Generally, it takes 5-10 minutes to complete.

Problems solved by technology

This patent has a high success rate for the injection and blood collection of large livestock such as cattle and horses, but its structure is complex, and it is not applicable to some small animals with small blood vessels that are difficult to see clearly on the skin surface

[0004] At present, the commonly used method is to cut the skin near the animal's veins to expose the veins to the outside, and then perform blood collection or intravenous injection. This method will cause greater damage to the animal, and it will take a while to cut the skin. It can only be healed, and the professional level of the operator is also high. If you are not careful, the veins of the animal will be cut.
