Embodiment Construction

[0046] The present disclosure provides a blood bridge limiter, which is used to limit two individuals in a conjoined symbiosis model and establish a blood bridge. The blood bridge limiter includes: two supports, a vascular cannula connector seat, Vascular cannula connector and two restraint rings. This disclosure fixes the necks of two individuals in the symbiosis model, and simultaneously connects the carotid artery of one individual in the symbiosis model with the jugular vein of the other individual in the symbiosis model by using a vascular cannula connector. The blood bridge improves the success rate of parabiosis model construction and shortens the time required for forming.

[0047] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0048] Certain embodiments of the ...

Abstract

The present disclosure provides a blood bridge limiter, which is used to limit two individuals in a conjoined symbiosis model and establish a blood bridge. The blood bridge limiter includes: two supports, a vascular cannula connector seat, Vascular cannula connector and two restraint rings. This disclosure fixes the necks of two individuals in the symbiosis model, which can avoid traditional symbiosis surgery operations, and at the same time limit the mutual attack between individuals, thereby improving the success rate of symbiosis model construction and shortening the time required for forming .

Description

technical field [0001] The present disclosure relates to the field of biological experiments, in particular to a blood bridge stopper. Background technique [0002] Conjoined symbiosis is used to pair different animal individuals to study biological systems or circulation-related issues. The two individuals have a common vascular system after surgical conjoined union, and the result is similar to that of human conjoined twins. The surgical technique of parabiosis in experimental animals was established by French physiologist Paul Bert in the 1860s using white albino rats. [0003] Currently, mice are preferentially used in the parabiosis model, but the relevant surgical procedures still follow Paul Bert's method: skin incisions are made along the adjacent flanks of the two individuals and adjacent flaps are sutured, and the peritoneum at the sutures forms a The common peritoneal cavity, where two individual blood vessels join to form an anastomosis due to revascularization ...
