Description
Technical field
The invention belongs to technical field of medical equipment more particularly to a kind of cardiovascular interventional operation site of puncture by press fitting
It puts.
Background technology
At present, it after cardiovascular intervention, needs to press the site of puncture of patient for a long time, artificial pressing is more
Fatigue, it is time-consuming and laborious.
Existing site of puncture press device intelligence degree is low；Cardiovascular interventional operation site of puncture cannot be pressed
Pressure carries out examinations, it is impossible to avoid unexpected generation.
Existing cardiovascular interventional operation site of puncture monitoring device generally existing decision condition is single, and false dismissal and false-alarm are general
Rate is high, and alarm signal transmits insecure problem.
RF power amplification is the important equipment in wireless communication system, and the higher line degree for ensureing RF power amplification is predistortion
Important foundation.It is non-linear to be continuously increased in RF power amplification During Process of Long-term Operation so that the delivery efficiency of power amplifier reduces, and causes

And communication transmission quality is seriously affected, reduce system performance；Simultaneously because non-linear increase power amplifier fever, device will be caused to add
Fast aging, it is therefore necessary to carry out power back-off.Conventional power compensating method power efficiency is beneath or complicated, cost compared with
High or Bandwidth-Constrained, stability are poor.Envelope-tracking adaptive digital pre-distortion can overcome disadvantages mentioned above.Currently, predistortion
Device can be divided into three classes according to its position in systems：1st, radio frequency (RF-RadioFrequency) pre-distortion technology (build by poplar

Radio frequency distortion (RF-RadioFrequency) and intermediate frequency predistortion (IF-IntermediateFrequency)
Belong to the scope of analog predistortion, higher efficiency and cheap cost are its advantages, disadvantage is that constantly update simulation
Parameter needs active device in radio frequency or intermediate frequency control analog device to adapt to the characteristic of power amplifier, implement it is relatively difficult,
It is only applicable to the occasions not high to linearity such as satellite system, the raising of feedforward linearized initial linear at present；Base band is pre-
Distortion can be handled at low frequency, can use DSP (DigitalSignalProcessor), FPGA
(FieldProgrammableGateArray) etc. the low frequency of signal is moved in high-speed digital signals processing chip realization, has spirit
Processing method living and stronger adaptability.Open source information shows：Envelope-tracking needs dynamic to adjust the more demanding of power supply
Supply voltage rather than use fixed voltage are powered.
The present invention provides a kind of self-adapted pre-distortion power amplifier, solves a kind of achievable different system switching, has
Highly sensitive and restructural envelope-tracking self-adapted pre-distortion power amplifier.
In conclusion problem of the existing technology is：After cardiovascular intervention, the site of puncture progress to patient is needed
Prolonged pressing, artificial pressing is more tired, time-consuming and laborious.
