Problems solved by technology

However, clinically, there is currently a lack of devices for real-time monitoring of the perfusate temperature, flow rate, and remaining fluid volume for this kind of low-temperature perfusion, and the perfusate is often taken out of the cooling device and operated at room temperature during the perfusion process. , has a certain influence on the perfusion effect

Embodiment Construction

[0022] The following will refer to the attached figure 1 , 2 , 3, 4, 5 and 6 further illustrate the technical solution of the present invention.

[0023] as attached figure 1 and 4 As shown, the single-chip microcomputer control system in the control system 1 can use the single-chip microcomputer C8051F021 as the driver board, coupled with an external 22.1184MHZ crystal oscillator. The vertical plug JTAG interface is provided for the convenience of downloading the program, the jumpers J4~J15 realize the switching of the multiplexing interface, and the bus interface parts P1, P2, P3, and P4 realize the connection of the FPGA user IO port. The power supply module TPS78633 provides +3.3V power supply for the single-chip microcomputer chip, and the indicator light +5.0V is the power indicator. The power supply can provide +5V through the bus or the POWER interface. The temperature monitoring element in the constant temperature cooling device can use the STYC series integrated ...

Abstract

The invention relates to a craniocerebral perfusion cooling portable box, comprising a control system (1), a constant temperature cooling device (2), a driving perfusion device (3), a power supply (4), an operation panel (5) and external interfaces (6, 7 ), wherein the control system (1) controls the flow of the perfusate in the constant temperature cooling device (2) through the external interface (6, 7) by controlling and driving the perfusion device (3); the constant temperature cooling device (2) ) built-in temperature monitoring element and water level monitoring element, the temperature monitoring element is used to monitor the temperature signal of the perfusate in the constant temperature cooling device (2) and the signal of monitoring room temperature, and the water level monitoring element is used to monitor the liquid level information of the perfusate The operation panel (5) can display information such as the perfusate temperature, flow rate and remaining liquid volume in real time, and can infuse the brain perfusion cooling solution with a certain volume and temperature in the range of 0-4°C into the brain at an appropriate rate Local area, so that the temperature in this area can reach mild hypothermia as soon as possible, so as to meet the demand of mild hypothermia treatment for ischemic brain injury.

Description

Technical field: [0001] The invention relates to a craniocerebral perfusion and cooling portable case, in particular to a local cooling and perfusion equipment for timely protection of brain function in patients with cerebral apoplexy and craniocerebral injury. Background technique: [0002] Cerebrovascular disease is a general term for a group of diseases caused by brain tissue blood supply disorders caused by various reasons. Its acute attack is called stroke, which has the characteristics of high incidence, high recurrence rate, high disability rate and high fatality rate. Clinically, cerebral apoplexy is divided into two categories: hemorrhagic and ischemic, and ischemic stroke accounts for more than 80% of the total incidence. When a blood vessel in the brain suddenly ruptures or bleeds, or cerebral ischemia or hypoxia occurs due to blood vessel blockage, local neurological deficits often result. [0003] Craniocerebral injury accounts for a large proportion of systemi...
