Ward, the continuous dynamic (dynamical) variation of monitor blood flow is to all kinds of critical patients such as cardiovascular diseases, more it is necessary to hypertension/low
Blood pressure is the direct cause of death of many high-risk patients.The study found that between blood pressure change rate and the death rate of cardiovascular disease
There is significant correlation.Therefore, pass through that continuous hemodynamic monitoring grasps blood pressure change rate and take appropriate measures can be with
The occurrence of greatly reducing the fatal risk as caused by blood stream rheology.
With the development of science and technology, also occurring a kind of more accurately monitoring device as shown in Figure 1 at present.Such as Fig. 1 institute
Show, which includes pressure sensor 81, data line 82, flusher 83, diversion pipe 84, trochar 85, working principle
As follows: flusher 83 is externally connected to the physiological saline containing heparin, and flusher 83 is fixedly connected on pressure sensor 81
On, inner conduit is in contact with the induction zone inside pressure sensor 81, and export end is connected with diversion pipe 84, diversion pipe 84
It is connected on trochar 85；Pressure sensor 81 is connected with data line 82, and one end of the data line 82 is provided with coffret

Extraction and casing 85 still remain in it is intravascular, 85 airtight connection of trochar on diversion pipe 84, flusher 83 at the same time
Interior heparin saline is also met in water conservancy diversion to diversion pipe 84 and close to one section of trochar 85 and the blood at upstream, is being pressed
Under the action of dynamic balance, which finally remains unchanged.The pressure of induction zone and blood pressure are one on pressure sensor 81 at this time
It causes.It is the pressure (angiosthenia/vein pressure) of blood vessel by the pressure that pressure sensor 81 measures, and is transmitted by data line 82
To analysis shows that being analyzed on instrument and showing result for medical staff's record, guiding clinical diagnosis and treatment.
Although above-mentioned disposable pressure sensor can accurately measure the blood pressure of patient, inside diversion pipe 84
Deflector hole it is excessively narrow, when backflow of blood to pipe in when it is easy to appear solidification the phenomenon that, this be just unfavorable for blood pressure carry out
Monitoring, pressure then cannot be accurately measured after blood clotting, needs to maintain blood in heparin saline fair current to diversion pipe 84
To prevent Hemostatic Oral Liquid solidification near 84 contact position of trochar 85 and diversion pipe, this just needs to add the flushing dress of water conservancy diversion heparin saline
83 are set, which adds cost, and it is inconvenient for operation.
