Description
Technical field
The present invention relates to medical diagnostic apparatus technical fields, and in particular to a kind of for obtaining the sensing of invasive aortic pressure
Device.
Background technique
Invasive blood pressure (IBP) can generally monitor: arterial pressure (ABP), central venous pressure (CVP), pulmonary arterial pressure (PAP),
PLA left atrial pressure (LAP), intracranial pressure (ICP).Its measuring principle is: conduit is placed in the intravascular of tested position by puncture first,
The outer end of conduit is directly connected with pressure sensor, and since fluid has pressure transmitting effect, endovascular pressure will pass through
Liquid in conduit is transmitted on external pressure sensor, thus can get the dynamic waveform of intravascular real-time pressure variation,
By specific calculation method, systolic pressure, diastolic pressure and the mean arterial pressure of tested position blood vessel can get.
Invasive blood pressure sensor is all disposably, to install new sensor each time, then need sensor manually
It is discharged with the air in pressure pipe.The height change of sensor will affect the measurement of pressure.The preparation of every operation is all
Many troubles are brought to patient and nurse, therefore a kind of energy of market in urgent need works independently, the acquisition of automatic exhaust and automatic zero adjustment
The device of invasive pressure.Application No. is the patent of invention of 201811093192X, " one kind is for acquisition when measuring blood flow reserve score
The device of aortic pressure " a kind of device is proposed, by increasing peristaltic pump between blood pressure sensor and bag of saline, utilize wriggling
Pump realizes self-bleeding function to squeeze perfusion tube.But it since blood pressure sensor is disposable utensil, more exchanges blood transfusion every time
It requires to reinstall peristaltic pump when pressure sensor, and needs again to pass through perfusion tube peristaltic pump, operate not simple enough.And
And in the disclosure in this patent, blood pressure acquisition terminal need to be connect by extension mouth with pressure display terminal without built-in display module
The pressure value that could show measurement, it is relatively complicated in actual use.
In addition, when measuring aortic pressure, when in pressure sensor pressure experience chip and heart in same level
Highly, it can accurately measure aortic pressure.Determining for pressure experience chip is realized without providing related miscellaneous function in the prior art
Position, it is only more time-consuming and laborious with being positioned manually.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of invasive blood pressure sensors easy to operate.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions: a kind of novel invasive blood pressure
Sensor, including pressure experience chip further include Wriggling Pump Head, and Wriggling Pump Head includes rotating wheel, and rotating wheel is equipped with and outside
The connection structure of electric machine rotational axis connection, Wriggling Pump Head are built-in with hose, and hose one end is connect with pressure experience chip, the other end
It is connect by perfusion tube with bag of saline.
Further, hose is equipped with female Luer with perfusion tube connecting pin and is connect with it with perfusion tube.
Further, the connection structure in rotating wheel is the square hole on wheel shaft, and external motor rotary shaft is square shaft.
Further, check valve is connected between hose and pressure experience chip, check valve allows to flow to as bag of saline extremely
Pressure experience chip.
It further, further include laser emitter, laser emitter and pressure experience chip are located at same level height.
It further, further include display screen, display screen includes numeric display area and waveform display area.
The invention has the beneficial effects that being integrated with Wriggling Pump Head in blood pressure sensor, hose is previously charged into peristaltic pump
In head, hose need to only be connect with the perfusion tube being connected in bag of saline, when saving more emat sensor into peristaltic pump
The operation for installing hose, can be further simplified the operating process of more emat sensor, keep the operation for installing sensor simpler.And
And hose is mounted in the installation effect in Wriggling Pump Head also superior to in-site installation when using in advance, can avoid in-site installation and improperly asks
Topic.
Detailed description of the invention
Fig. 1 is one embodiment of the invention structural schematic diagram；
Fig. 2 is the connection schematic diagram of Wriggling Pump Head and external motor in one embodiment of the invention.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the present invention will be described in detail:
One embodiment of the invention is as depicted in figs. 1 and 2, a kind of novel invasive blood pressure sensor, including pressure experience chip 1, also
Including Wriggling Pump Head 2, Wriggling Pump Head 2 includes rotating wheel 21, and rotating wheel 21 is equipped with the connection that axis connection is rotated with external motor 8
Structure, Wriggling Pump Head 2 are built-in with hose 3, and 3 one end of hose is connect with pressure experience chip 1, and the other end passes through perfusion tube and salt water
Bag connection.
Blood pressure sensor one end is connect with bag of saline, and the other end is connected to patient sustainer by external device (ED), and blood pressure passes
The purposes of sensor is exactly to connect patient sustainer, and centre can form access, sensor with aorta full of physiological saline
There is pressure experience chip 1 in inside, the dynamic pressure of aorta can be converted into analog signal, inside blood pressure sensor
Collected analog signal is converted into digital model by circuit, obtains systolic pressure, diastolic pressure and the mean pressure of aortic pressure.
In use, hose 3 is connect with perfusion tube, the rotating wheel 21 of Wriggling Pump Head 2 is connect with external motor 8, external electrical
