Problems solved by technology

[0003] The traditional pig blood collection process adopts the exposed blood collection method, and the pig blood is directly in contact with the air, which cannot avoid blood pollution and cause great economic losses. One of the very important reasons is that the live pigs to be blood collected cannot be effectively fixed

Embodiment 1

[0025] Such as Figure 1-3 As shown, a pig's aseptic blood collection fixture includes a platform 1, a bracket 2 is arranged under the platform 1, and two side panels 3 are arranged on the upper part, and the two side panels 3 are arranged obliquely, so that the side panels 3 The cross-section of the space formed by the platen 1 is funnel-shaped, and the top edge of each side plate 3 is provided with two clamping foot devices. One end of the platen 1 is provided with a headband 4, and one end is connected to the platen 1 through a rotating shaft 5. The other end is provided with two extensions 6, and the platen 1 is provided with a through hole 7 corresponding to the extension 6 on the headband 4, so that the extension 3 can be inserted into the through hole 7, and the extension The long section 3 is provided with five scale grooves 8, and the bottom of the platen 1 is provided with two locking strips 9. One end of the locking strips 9 is axially connected to the bottom of the...

Embodiment 2

[0030] A fixed blood taking method for pigs, using the above-mentioned aseptic blood taking fixing device, the fixing steps include:

[0031] 1) Fixing: Open the headband, unfasten the fixing belt, lift the pig upside down above the platform, then put the pig on the platform, fall into the space formed by the two side panels and the platform, and pass the limbs through the cardboard. The foot device is fixed, the arched mouth of the pig is placed on the headband, close the headband, insert the appropriate length of the extension section into the through hole on the platen according to the size of the pig's head, and then snap the two clips into an extension Scale groove in the segment to fix the pig's head;

[0032] 2) Blood collection: After the pig is fixed, sterilize the skin of the neck, spread a sterile surgical drape, cut the skin tissue with a scalpel, probe the pulsating common carotid artery, take the five sense surgical scissors to peel off the fascia on the artery, ...

Abstract

The invention relates to an aseptic blood-taking fixture for pigs, comprising a platform, a bracket is arranged under the platform, and two side panels are arranged on the upper part, and the two side panels are arranged obliquely so that the space formed by the side panels and the platform The cross-section is funnel-shaped, and the top edge of each side plate is provided with two clamping foot devices. One end of the table is provided with a headband. One end of the headband is connected to the table through a rotating shaft, and two extensions are provided at the other , the platen is provided with a through hole corresponding to the elongated section on the headband, so that the elongated section can be inserted into the through hole, the elongated section is provided with a scale groove, and the bottom of the platen is provided with a The two clamping strips can be snapped into the scale groove when the scale groove runs below the platen. Also included is a method of taking blood using the device. The invention can achieve aseptic blood collection, avoid blood contamination, and improve the yield and antibody titer of blood products.

Description

technical field [0001] The invention relates to the technical field of biopharmaceuticals, in particular to a pig aseptic blood-taking fixing device and a fixed blood-taking method. Background technique [0002] The development prospects of China's biomedical industry are promising, and will maintain a good momentum of steady growth in the next 5-10 years. Among them, pig blood is the key raw material for the production of drugs such as coagulase and anti-human T cell porcine immunoglobulin, and the quality of pig blood directly affects the yield and antibody titer of the product. [0003] The traditional pig blood collection process adopts the exposed blood collection method, and the pig blood is directly in contact with the air, which cannot avoid blood pollution and cause great economic losses. One of the very important reasons is that the live pigs to be blood collected cannot be effectively fixed. Contents of the invention [0004] The purpose of the present inventio...
