However, it will be apparent to one skilled in the art that the present application may be practiced without one or more of these details. In other instances, well-known features have not been described in detail so as not to obscure the application; that is, not all features of an actual implementation are described in detail herein, and well-known functions and constructions are not described in detail.
For a thorough understanding of the present application, detailed steps and detailed structures will be presented in the following description in order to explain the technical aspects of the present application. Preferred embodiments of the present application are described in detail below, however, the present application may have other implementations in addition to these detailed descriptions.
The inventors found in research and development that there are many reasons for the insufficient stability of the implementation effect, but the main problems include: the timing of counterpulsation and deflation is not accurate enough, the air pressure of counterpulsation and inflation is not matched, etc. Therefore, the inventors have further developed and proposed the following technical solutions.
Example 1
An embodiment of the present application provides a counterpulsation assistance device 100, referring to fig. 1, the counterpulsation assistance device 100 includes:
a first acquisition module 101, configured to acquire a blood flow spectrum envelope through a doppler blood flow detector; the blood flow spectrum envelope is obtained from a blood vessel under the action of counterpulsation;
a second obtaining module 102, configured to obtain at least one blood flow parameter of the blood vessel according to the blood flow spectrum envelope;
a first adjusting module 103, configured to determine an implementation parameter of a counterpulsation apparatus according to the blood flow parameter, and send the implementation parameter to the counterpulsation apparatus; the counterpulsation apparatus is an apparatus for counterpulsating a blood vessel.
The Doppler blood flow detector can accurately detect various blood flow parameters, and can be used for evaluating the effect of counterpulsation according to the blood flow parameters so as to adjust the implementation parameters of counterpulsation.
Specifically, the blood flow parameters can be obtained through the blood flow spectrum envelope, and the blood flow parameters are more scientific and accurate. See in particular the description below.
The counterpulsation apparatus-specific counterpulsation parameters need to be sent to the counterpulsation apparatus for implementation.
The counterpulsation apparatus may include, but is not limited to, enhanced external counterpulsation EECP, aortic balloon counterpulsation IABP, and the like. The process of acquiring the blood flow spectrum envelope in the Doppler blood flow detector is briefly described as follows:
acquiring a plurality of rows of power spectral densities S (n) of the Doppler blood flow signals, and obtaining an integral curve P (n) corresponding to each row of power spectral densities S (n);
and determining a maximum flow speed point on the integral curve P (n), and connecting the maximum flow speed points determined by each column to obtain a spectrum envelope curve. Since the spectral envelope curve is the maximum flow velocity point connecting the columns, it is also a waveform curve reflecting the flow velocity of the blood flow. Thus, parameters related to the blood flow velocity integral (Velocity Time Integral, VTI) and the like can be obtained through the spectrum envelope curve, and the obtaining process is well known to those skilled in the art, and will not be repeated herein.
More specifically, as shown in fig. 2, the envelope processing of the ultrasound doppler data may include the steps of:
step 201: starting. The program is initialized.
Step 202: column data is input. I.e. the power spectral density S (n) of each column.
Step 203: the power spectral density is integrated with frequency to obtain P (n).
Step 204: the origin is connected to an end point straight line of the power spectral density integration, and an intersection point (Vcross, P (Vcross)) of the straight line and P (n) is obtained.
Step 205: the ordinate lowest of the minimum value of S (1) to S (Vcross) is found.
Step 206: the new integral curve P (m) of S (lowest) to S (2 x vcross-lowest) is found.
Step 207: and connecting the ends of the P (m) to form a straight line, and solving the positive and negative maximum distances from the integral curve P (m) to the straight line. The positive maximum distance is the maximum flow rate point and the negative maximum distance is the minimum flow rate point.
Step 208: and (5) ending.
According to the counterpulsation assisting device 100 provided by the embodiment of the application, the blood flow spectrum envelope of the blood vessel under counterpulsation is obtained through the Doppler blood flow detector, the blood flow parameters are obtained according to the blood flow spectrum envelope, and then the implementation parameters of the counterpulsation device are determined according to the blood flow parameters, so that the stability of the implementation effect can be improved.
In some embodiments, the second acquisition module 102 is further configured to:
acquiring interval time of spontaneous heart beat and counterpulsation according to the blood flow spectrum envelope;
the first adjustment module 103 is further configured to:
and determining the time parameter of the counterpulsation according to the interval time.
Referring to fig. 3, the envelope shapes of the spontaneous heart beat and counterpulsation in the blood flow spectral envelope are different, e.g., the two peaks are not so high, so that the interval time between the spontaneous heart beat and counterpulsation, e.g., the time between the two peaks, can be obtained from the blood flow spectral envelope.
From the interval time, a time parameter of the counterpulsation may be determined, such as an on-time point of counterpulsation, a duration, etc., relative to the heart rate of the user. Based on the time parameter, a degree of cooperation of the counterpulsation and the heart rate of the user can then be determined for transmission to the counterpulsation apparatus for adjustment. For example, if the counterpulsation time is too late, it may occur that the counterpulsation envelope and the envelope of the spontaneous heart beat are difficult to form a good V-shape, which is a common effective morphology of counterpulsation. The setting of the interval time can be adjusted according to the heart rate of the user, and also can be adjusted according to the envelope waveform.
It will be appreciated that the adjustment may be a fine adjustment. Because, in general, the counterpulsation in the prior art is relatively small in deviation and is not easily found. The user is a living being acted upon by the counterpulsation apparatus, and for the purpose of distinction, the person operating the counterpulsation apparatus is referred to as the staff.
In some embodiments, the counterpulsation apparatus may be an external counterpulsation apparatus;
the second acquisition module 102 is further configured to:
acquiring the blood flow velocity ratio of counterpulsation and spontaneous heart beat according to the blood flow spectrum envelope;
the first adjustment module 103 is further configured to:
and determining the aeration pressure of the counterpulsation according to the blood flow speed ratio.
The ratio of the blood flow rates of counterpulsation and spontaneous heart beat can show whether the aeration pressure of counterpulsation is proper. Thus, the inflation pressure of the counterpulsation may be determined based on the blood flow velocity ratio, for delivery to a counterpulsation device for regulation.
Specifically, the blood flow velocity of the spontaneous heart beat may be the maximum velocity of blood flow during the spontaneous heart beat minus the minimum velocity of blood flow, referred to as S; the blood flow velocity of counterpulsation may be the maximum velocity of blood flow during counterpulsation minus the minimum velocity of blood flow, referred to as D; the ratio of blood flow velocity for counterpulsation and spontaneous heart beat may be D/S.
Specifically, a D/S greater than 1.2 indicates that the inflation pressure is normal, otherwise the inflation pressure needs to be adjusted. The ratio of 1.2 can be adjusted for different users. For example, it may be 1 to 1.5.
The external counterpulsation apparatus of the present embodiment may be EECP technology, but is not limited to other modes of counterpulsation.
In some embodiments, the second acquisition module 102 is further configured to:
an autonomic heart beat portion and a counterpulsation portion in a blood flow spectral envelope are identified.
In addition to the difference in peak height, the overall envelope shapes of the spontaneous heart beat portion and counterpulsation portion are also different and can be identified by certain rules.
In particular, an identified algorithm or model may be designed and trained with a large number of samples. The trained algorithm may be used to identify the spontaneous heart beat portion and counterpulsation portion of the blood flow spectral envelope.
In some embodiments, the second acquisition module 102 is further configured to:
