Description
Technical field
The present invention relates to the medical instruments field supported for extracorporeal life more particularly to a kind of cardiopulmonary bypass systems.
Background technique
Cardiopulmonary bypass system, also known as extracorporeal membrane oxygenation (extracorporeal membrane oxygenation,
It ECMO), is a kind of mechanical cycles ancillary technique that can be percutaneously placed in.Cardiopulmonary bypass system is usually by host, pump head and membrane type oxygen
Three parts of clutch are constituted.Host controls and monitors the operation of cardiopulmonary bypass system, and pump head is used to make the blood of inside and outside
Liquid is recycled, and membrane oxygenator is used to provide the carbon dioxide in the blood being discharged in oxygen and permutoid.Cardiopulmonary bypass system
The venous blood for primary drainage patient's body of uniting is to external, after membrane oxygenator oxygen merges the carbon dioxide excluded in blood
Blood recovery patient's body.Different according to the approach of blood recovery, cardiopulmonary bypass system mainly has vein to vein
(venovenous ECMO, VV-ECMO) and vein to two kinds of forms of artery (venous-arterial ECMO, VA-ECMO),
The former only has Respiration assistance effect, and the latter has circulation and Respiration assistance effect simultaneously.
Since cardiopulmonary bypass system is commonly used in transportation of patients between patient's first aid and hospital, but the host of cardiopulmonary bypass system
Weight is greater than 10 kilograms, and the power supply in host can be not required to connection alternating current and use, but its time that works independently is shorter, and cardiopulmonary is caused to turn
The Portability of streaming system is bad.Certainly it can also select directly directly to supply electricity to pump head by battery, pump head is direct without using host
Drive membrane oxygenator operating, but in such a mode, can not detect because there is no host from the flow of the blood being discharged in vivo and
Bubble brings security risk instead.

10133 pretreatment signal sensed from flux, temperature sensor signal, pressure sensor signal and blood oxygen saturation transducing signal, at second
Reason device 10133 transmits pretreated signal sensed from flux, temperature sensor signal, pressure sensor signal and blood oxygen saturation sensing letter
Number to first processor 1011, first processor 1011 is passed according to pretreated signal sensed from flux, temperature sensor signal, pressure
Sense signal and blood oxygen saturation transducing signal learn the shape of the blood such as flow, temperature, pressure and the blood oxygen saturation of current blood
State data.User can be by input module 105 prior to first setting flow, temperature, pressure and blood oxygen in first processor 1011
The monitoring threshold value of saturation degree, portable type processor 111 judge at least one in blood flow, temperature, pressure and blood oxygen saturation
Whether person is more than corresponding monitoring threshold value, if judging, at least one of blood flow, temperature, pressure and blood oxygen saturation are more than
When monitoring threshold value, first processor 1011 generates alarm signal, and transmits alarm signal to display module 104, display module
104 show information warning according to alarm signal, and user can make other medical measures by information warning.
The power module 102 of the monitoring host 10 of the present embodiment can use the AC power source of alternating current, could be used that vehicle-mounted
DC power supply, moreover it is possible to using the DC power supply of built-in battery 1023, so monitoring host 10 can be in the state of not stabilized power supply
Lower use, the DC power supply of the vehicle-mounted DC power supply of cross-reference and built-in battery 1023 in the state of no stabilized power supply,
To extend working time of the monitoring host 10 in the state of no stabilized power supply.
