Problems solved by technology

This technique can only remove toxic substances and smooth blood vessels in the amputated limb, but cannot effectively prevent the continuation of tissue necrosis, nor can it provide the oxygen and nutrients needed for tissue survival, and it can only make the amputated limb alive within a very limited period of time. or survive a severed finger

Abstract

The invention relates to a culture apparatus for an amputative limb or a severed finger, which comprises a container, wherein perfusate is filled into the container; a liquid output end of the perfusate container is communicated to a blood pump for supplying perfusate power through a pipe; a liquid output end of the blood pump is communicated with an oxygen-laden artificial lung for supplying blood and gas exchange through a pipe; a liquid output end of the artificial lung is communicated with an arterial blood vessel of the amputative lumb or the severed finger through a pipe; and the amputative limb or the severed finger is placed into an airtight constant temperature monitor. The culture apparatus for the amputative limb or the severed finger can reduce the tissue metabolic rate of the amputative limb or the severed finger under the isolated state, recovers and maintains tissue survival of the amputative limb to the maximum degree, eliminates necrotic tissue and toxin, and converts the replantation time limit of the amputative limb into a parameter capable of being manually controlled and effectively prolonged.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical device for monitoring broken limbs and severed fingers. Background technique [0002] After a large limb amputation injury is caused by various reasons, such as a severed limb (finger) ischemic time is too long, due to hypoxia and other reasons, cells undergo degeneration, necrosis, and finally irreversible degeneration. At this time, even if the blood vessel is connected and the blood flow is restored, the amputated limb (finger) not only cannot survive, but may cause poisoning or even death due to the absorption of a large number of metabolites and toxins. Therefore, the time until the blood supply of a broken limb (finger) is interrupted and can be replanted is not infinite, but has a certain limit. This limit is called the replantation time limit. The time limit for replantation is not absolute, but relative. It is related to the height of the severed limb, the amount of muscle ...
