Embodiment Construction

[0026] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0027] The method for collecting live pig plasma of the present invention mainly includes live pig immunization, closed healthy breeding, detection of pig blood pathogens, healthy pig capture and fixation and waiting for collection, cleaning and disinfection of the surface of the collection site, puncture and pre-embedded collection catheters, and automatic connection. Processes such as supporting consumables for pulp harvesters, automatic collection, quick freezing, and window period detection of zoonotic diseases.

[0028] Before collecting live pig plasma, it is first required to select healthy young pig numbers for immunization against animal diseases such as foot-and-mouth disease, highly pathogenic porcine blue-ear disease, and swine fever. The immunization procedures here are carr...

Abstract

The invention provides a method for collecting plasma of a live pig. The method comprises the following steps: 1, binding the whole body of the pig to be subjected to plasma collection, and fixing the bound pig to a blood collecting vehicle; 2, carrying out disinfection treatment on the selected head-neck part of the pig to be subjected to plasma collection; 3, slowly puncturing the head-neck part of the pig to be subjected to plasma collection by adopting a puncture needle connected with an injection syringe, pulling out the injection syringe when red blood appears in the injection syringe, inserting a guide wire into the puncture needle, and pulling out the puncture needle; and 4, slowly pushing a collecting catheter into the blood vessel along the guide wire, and pulling out the guide wire. With the method for collecting the plasma of the live pig, the plasma of the pig can be effectively and conveniently obtained, and does not need secondary separation, and therefore, the environmental pollution and the secondary pollution caused by the environment to the plasma are reduced; meanwhile, the initial bacterium contamination number of the plasma is reduced, the transmission of the zoonotic diseases is completely eradicated, the hemolysis phenomenon is avoided, and thus a reliable quality guarantee is provided for a biological product taking the plasma of the pig as the raw material.

Description

technical field [0001] The invention relates to a plasma collection method, in particular to a method for collecting live pig plasma. Background technique [0002] In the medical field, with the rapid development of medical technology, in order to reduce the dependence of clinical pharmaceutical products on human plasma, it is more and more inclined to use animal plasma. For example, biomedical products such as pig-derived fibrin adhesives, which use live pig plasma as the main raw material, have been widely used in clinical surgery. Especially after organ surgery, such products can be sprayed on the wound surface instead of suturing, which can quickly complete the hemostasis of the wound surface, thereby reducing the risk of diffuse bleeding for patients after surgery. This can effectively reduce the patient's surgical pain and reduce the clinical blood demand, which has significant benefits to the society. [0003] However, at present, the raw materials of relevant bioph...
