Calf artery blood sampling method

Abstract

The invention discloses a calf artery blood sampling method. The calf artery blood sampling method includes the following steps that 1), a blood collecting barrel is washed with pure water 2-3 times,then the blood collecting barrel is soaked with 75% medical alcohol for 30-50 min, and the blood collecting barrel is put in a clean region for use after being dried; 2), a medical silicone tube and ablood receiving tool which are soaked with 2% sodium hydroxide are flushed with pure water 2-5 times, and then a blood drawing tool and a blood sampling tube with the two ends seal-bound by tin foilpaper are put in a high-pressure sterilization pot to be sterilized for use; 3), a calf is put on an operating table, conventional skin preparation is carried out on the neck artery of the calf, and then the skin is disinfected with a 5% bromogeramine solution; 4), after the skin is disinfected, the neck of the calf is cut up, an artery blood vessel is found, a small opening is cut up, the medicalsilicone tube is inserted into the small opening, the other end of the medical silicone tube is put in an inlet of the blood collecting barrel, and blood sampling is carried out. By means of the blood sampling method, rapid blood sampling can be achieved, the blood sampling amount is large, blood samples are not easily contaminated, and the method is suitable or large-scale use and popularization.

Description

technical field [0001] The invention relates to the technical field of medical experiments, in particular to a calf artery blood collection method. Background technique [0002] The production and preparation of animal antiserum generally requires the animal to be inspected and then bled. The current method of blood collection and bloodletting mainly includes orbital blood collection, capillary blood collection, heart blood collection, decapitation blood collection and so on. Among them, when blood is collected from the orbit, the operator’s left thumb and index finger gently press the sides of the neck to congest the orbital venous plexus, and then use a blood collection needle to enter the blood collection; capillary blood collection is generally used when the blood volume is small Blood sampling is performed at the finger or heel; heart blood sampling generally has strict requirements. If the heart is punctured through the body surface, the depth of the needle and the in...

Problems solved by technology

Among them, when blood is collected from the orbit, the operator’s left thumb and index finger gently press the sides of the neck to congest the orbital venous plexus, and then use a blood collection needle to enter the blood collection; capillary blood collection is generally used when the blood volume is small Blood sampling is performed at the finger or heel; heart blood sampling generally has strict requirements. If the heart is punctured through the body surface, the depth of the needle and the inner diameter of the needle will affect the speed and quantity of blood sampling. The quality of the blood collected, but the animal will die quickly by cutting the chest of the animal, which will seriously affect the amount of blood collected; as the name implies, the neck of the animal is directly cut off, and then the blood is collected. The blood sample is contaminated by tissue fluid, which will affect the subsequent production, and the blood collection method is cruel and bloody, which is not suitable for the public to accept
