Abstract
The utility model belongs to a medical instrument, and is a new safety device (pump pressure monitoring device) used for extracorporeal circulation. The utility model is composed of a pump pressure monitoring system and an automatic pressure reducing system. The major technical feature is that an electric contact point pressure gauge is used as a pressure positioning device, a side way pipe is used to leak pressure, and a spring electric pressure-reducing valve is used as a pressure reducing sluice gate. The rupture of pump pipe and the collapsing and dropping of pipe joint caused by pump pressure heightening of the extracorporeal circulation can be prevented via the medical instrument. The slipping of arterial catheter, the air entering of artery, and various severe accidents jeopardizing lives of patients can be prevented via the medical instrument. The utility model belongs to an invention invented firstly at home and abroad.
Description
The invention belongs to Medical Instruments, be used for extracorporeal circulation pump pressure supervising device.
Because pump pressure increases and often causes pump line to break, pipe joint is collapsed and is taken off, arterial cannulation slippage, tremulous pulse air inlet, the multiple major accidents that jeopardize patient's life such as blood pump motor short circuit in the extracorporeal circulation.Domestic still do not have safety equipment in this respect.Have only simple Pump pressure meter abroad, do not have automatic decompressor.
The purpose of monitoring of invention extracorporeal circulation pump pressure and automatic decompressor is exactly in order to monitor and to control the pressure of heart-lung machine's blood pump, preventing the various extracorporeal circulation serious accidents that cause owing to the blood pump increased pressure.
Pump pressure monitoring and automatic decompressor are made up of continuous pump pressure monitoring system and Automatic Pressure Relief System two parts.The pressure gauge of pump pressure monitoring system communicates with the pump line high-pressure side continuously.Can directly measure the pump line internal pressure continuously, its pressure measurement scope is at 0-735mmHg.The decompression localizer is housed in the Pump pressure meter, can in 0-735mmHg, regulates the decompression dividing value arbitrarily.When the pump line internal pressure reaches the predetermined pressure relief dividing value, send light and audio alarm, the automatic decompressor of being satisfied with in the bypass of tremulous pulse pipeline is opened automatically, makes the shunt valve pressure release, and the pump line internal pressure is reduced in rapidly that blood does not directly contact with decompressor in the decompression.
Automatically decompressor is the electronic air relief valve of spring, at ordinary times because spring pressure makes bypass duct inaccessible when increased pressure, the electric contact localizer is connected circuit in the Pump pressure meter, the drawing magnetism of electronic air relief valve makes electronic air relief valve open, bypass duct is unimpeded, and the pump line inner blood leaks into artificial lung pump line internal pressure through bypass and descends.
Utilize shown in the accompanying drawing, invention is further specified.

Fig. 2. the circuit connection diagram
Fig. 3. automatic decompressor structure chart
In Fig. 1, described pump pressure monitoring and the automatic decompressor continuous pressure gauge of connected mode in the extracorporeal circulation pipeline and 4. 3. be connected in 2. high-pressure side of blood pump by liquid gas pressure transmission pipeline.9. automatic decompressor is installed on shunt valve and 8. goes up, and 1. the shunt valve connection filter 7. tremulous pulse pipeline of near-end feeds artificial lung.
Fig. 2 is the circuit connection diagram, when decompression after 5. localizer be triggered, through time delay conversion circuit (11) control alarm lamp 6. with alarm speaker 10. and decompressor 9..
Fig. 3 is automatic decompressor structure, and spring (14) makes air relief valve (16) press off shunt valve 8., and voltage regulation screw (15) is regulating spring pressure arbitrarily, when localizer triggers, when circuit was connected, tractive magnet (13) made air relief valve (16) open the shunt valve releasing pressure automatically.Its connected mode is: an end of spring is a voltage regulation screw, and the other end withstands on the tractive magnet stamen spring base, and Magnet has drift bolt to link to each other with electronic air relief valve.
