Embodiment 1

[0031] Preparations before blood collection: turn on the ultraviolet lamp in the blood collection workshop, sterilize the entire workshop for 30 minutes, and turn off the ultraviolet lamp after the sterilization is completed. Check whether the water and electricity are normal; turn on the hoist for a trial run. Unload the sterilized blood collection tools from the vehicle and place them in a fixed position in the workshop.

[0032] Washing hands: Wet your hands with water first, then apply soap, and then rub your palms, backs of hands, wrists, fingers, and nails repeatedly until a lot of foam appears; then rinse your hands with water, and rub them while rinsing until your hands are not greasy. Wear a mask, gloves.

[0033] Disinfect hands: use a watering can filled with 75% alcohol, spray on the hands, and spray 3 times on the palm and back of each hand.

[0034] Disinfect the tool cart table: wipe the tool cart table with 75% alcohol.

[0035] Blood collection tools: Each ...

Embodiment 2

[0043] Such as Figure 1~2 As shown, a pig aseptic blood collection process, the pig is clamped with the pig clamp 3, and hangs upside down on the track 2 through the movable hinge 1, the pig clamp 3 is fixed on the frame 4, and the pig clamp has multiple , the pig clamp adopts electric cylinder 5 to control its opening and closing. Each pig clamp is a station, and each station has two tracks for pigs to enter and exit. Live pigs enter the station through one track to collect blood. A track is transported out of the station. Fix the entire fixing device with the pig in the sterilized airtight blood collection system, and perform aseptic blood collection by puncturing the heart of the pig and the large blood vessels connected to the heart. The airtight blood collection system is sterilized by moist heat. Connect the puncture needle to the blood collection container with a catheter, and collect the blood at a speed of 0.5-5 L / 1-10 minutes, and a blood collection volume of 0.5-5...

Embodiment 3

[0045] Fix the entire fixing device with the pig in the sterilized airtight blood collection system, and perform aseptic blood collection by puncturing the heart of the pig and the large blood vessels connected to the heart. The airtight blood collection system is sterilized by moist heat. Connect the puncture needle to the blood collection container with a catheter, and collect the blood at a speed of 2-3 L / 1-4 minutes, and a blood sampling volume of 2-3 L / 100 kg / pig. The puncture needle is a tubular puncture needle with a diameter of 4 to 5 cm and a length of 50 to 70 cm. The material is made of glass material that is chemically stable and can withstand strong acids and alkalis. The tubular puncture needle is a disposable Use, washable, and withstand the above-mentioned moist heat sterilization treatment. The blood collection container is made of chemically stable plastic material that can withstand strong acid and strong alkali, can withstand sterilization methods, and is d...

Abstract

The invention relates to a process and a device for sterile blood sampling of live pigs. The process comprises: fixing a live pig in a sterilized hermetic blood sampling system; puncturing the heart the live pig and the great vessel connected with the heart through a puncture needle to perform sterile blood sampling; and connecting the puncture needle with a blood collection container through a duct to collect blood, wherein the blood sampling speed is 0.5 to 5 L / 1 to 10 minutes, and the blood sampling amount is 0.5 to 5 L / 100 kg / pig. Compared with the prior art, the process has the advantages of simplicity, easy implementation, effective prevention of microbial contamination to pig blood, low cost and the like.

Description

technical field [0001] The invention relates to an animal fibrin glue material, in particular to a pig aseptic blood collection process and device. Background technique [0002] Pig blood is a great resource. Whole blood contains 18% protein, of which plasma accounts for 65% of whole blood and contains 8% protein, and red blood cells account for 35% of whole blood and protein content is 36%. Fibrinogen and thrombin are extracted from pig blood. After a series of processes, they can replace human blood and prepare an effective hemostatic agent—fibrin glue, which can immediately prevent surgical field bleeding and small vein bleeding. At the same time, effective tissue sealing is implemented on the surgical wound, which effectively reduces the exudation of tissue fluid and accelerates wound healing. A large number of clinical application research results confirm the effectiveness and safety of the product. [0003] The biggest risk of medical biomaterials made from pig bloo...
