Problems solved by technology

[0003] After a long period of immunization, the value of animal antiserum is very high, so every 1ml of blood released is very important for production and preparation. The natural bloodletting method currently used cannot maximize the collection of animal blood, resulting in great waste; Due to the large amount of blood collect...

Embodiment 1

[0026] A special tool for animal arterial blood collection, comprising: a pipette tip 1, a blood collection tube 2, and a blood container; the pipette tip 1 is made of polyethylene material, and the head of the pipette tip 1 is conical. The angle between the end face of the pipette head and the axis of the pipette head 1 is 20-50°, and the tail is tubular. An ear hook 5 is arranged on the tube wall at the end of the tail away from the head, and the ear hook 5 is inclined to the end of the tail away from the head; The blood vessel 2 is made of polyethylene, one end of the blood collection tube 2 is connected to the tail of the pipette tip 1, and the other end is sealed with a polyethylene film 6; Sealing; the blood container can generate negative pressure, the closed end of the blood collection tube 2 can penetrate the silica gel, and the polyethylene film 6 is broken under the negative pressure, and the blood is collected through the negative pressure. The blood container is a...

Embodiment 2

[0030] It is basically the same as the blood collection tool in Example 1, except that a groove 4 is provided on the pipe wall at the end of the pipette head 1 near the head, and the blood container is a pressure-resistant cylinder with a built-in medical polyethylene blood bag 7. The solvent of the blood bag is 1.2~1.3 times of the blood collection volume. The body of the blood bag is located in the pressure-resistant cylinder 7, and the mouth of the bag is located outside the pressure-resistant cylinder 7. The pressure-resistant cylinder 7 is provided with an air nozzle 11. The cylinder cover 8 of the pressure-resistant cylinder 7 is two semi-conical bodies, the top of the semi-conical bodies is provided with a semi-circular notch 9, and the edge of the semi-conical bodies is provided with a sealing gasket 10, and the size of the notch 9 is the same as that of the neck of the blood bag. Matching, the size of the bottom of the half-cone matches the size of the body of the pres...

Embodiment 3

[0033] Embodiment 3 is basically the same as Example 1, except that the pipette tip 1 adopts a disposable pipette tip 1. When making it, a section is obliquely cut from the head of the pipette tip 1, and then the clipped This section is glued to the top of the pipette tip 1 by an alcohol lamp to form an ear hook 5 .

Abstract

The invention relates to a tool special for animal artery blood sampling, and discloses a tool special for sheep artery blood sampling. The tool comprises a liquid relief spearhead, a blood sampling tube and a blood containing container. The liquid relief spearhead is made of polyethylene materials. The head of the liquid relief spearhead is conical, and the included angle formed between the end face of the head and the axis of the liquid relief spearhead is 20-50 degrees, the tail of the liquid relief spearhead is tubular, an ear hook is arranged at the tube wall of the end, away from the head, of the tail, and the ear hook inclines towards the end, away from the head, of the tail; the blood sampling tube is made of polyethylene materials, one end of the blood sampling tube is connected with the tail of the liquid relief spearhead, and the other end of the blood sampling tube is closed by a polyethylene film; a cover is arranged at an opening of the blood containing container, silica gel is arranged in the center of the cover, and the blood containing container is sealed by the cover; the blood containing container can generate negative pressure, the closed end of the blood sampling tube can penetrate through the silica gel, the polyethylene film is broken under the negative pressure, and blood is sampled under the negative pressure. The tool has the advantages that the liquid relief spearhead is fixed firmly and is not likely to be disengaged; in the blood sampling process, the tool is totally closed, so that the probability that blood is polluted is lowered; blood is sampled by adopting negative pressure, and the amount of the sampled blood can be increased by 10-30% compared with conventional blood sampling.

Description

technical field [0001] The invention belongs to the field of veterinary medical instruments, and in particular relates to a special tool for animal arterial blood collection. Background technique [0002] The production and preparation of animal antiserum can be bled after passing the titer test. If it is intended to be killed by bloodletting at one time, the method of carotid artery bloodletting can be used: make the animal lie supine and fix the limbs, clip the hair on the neck, and after disinfection, cut the skin of the front neck longitudinally about 5-10 cm long to expose the pulsating carotid artery. The end is ligated with silk thread, the proximal end is clamped with arterial forceps, alcohol cotton balls are used to disinfect around the blood vessel, a V-shaped gap is cut with sterile scissors, a section of plastic tube is taken, one end is cut into a needle-like slope, and this end is inserted into the In the carotid artery, the other end was put into a sterile t...
