Embodiment Construction

[0034] Figure 1 to Figure 4 It is a schematic diagram of the appearance and structure of the semi-conductor refrigerated intravascular mild hypothermia cerebral protection therapeutic apparatus according to the present invention. The semi-low temperature intravascular cerebral protection therapeutic apparatus with semiconductor refrigeration mainly includes a point-type temperature sensing device in the blood vessel, an infusion temperature constant temperature device, a control device, a power supply device and the like. Except the intravascular temperature sensing device 3, all other devices are enclosed in the airtight casing. refer to figure 1 As shown, the chassis is divided into a control part 1 and a cooling part 2 by a partition. The control part 1 has a power switch 12, a temperature controller 11 and a control circuit board (not shown in the figure). A low-temperature chamber 212 is arranged on the upper side of the refrigerating part 2 , and its cover 211 is mov...

Abstract

A sublow-temp cerebral protecting and therapeutic apparatus with semiconductor refrigeration is composed of a point-type temp sensor arranged in blood vessel, a constant-temp device for outputting sublow-temp perfusion and delivering it via blood vessel into cerebral region, a controller for the closed-loop control to the temp of perfusion, and a power supply. It can decrease the complications.

Description

technical field [0001] The invention relates to a brain protection therapeutic apparatus, in particular to a sub-low temperature brain protection therapeutic apparatus for treating cerebrovascular diseases by adopting semiconductor refrigeration technology, and belongs to the technical field of medical instruments. Background technique [0002] At present, cerebrovascular disease has become one of the three major diseases threatening human health, ranking first in northern my country. With the acceleration of the aging process of the world's population, the major social and economic problems caused by cerebrovascular diseases have attracted great attention from governments of all countries. [0003] In order to effectively prevent and treat cerebrovascular diseases, anti-ischemia / reperfusion therapy is often used clinically. However, in the process of using this treatment method, how to reduce the disability rate and mortality rate of patients with cerebral infarction has b...
