The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can have other embodiments.

[0055] Embodiment One ​

[0056] The embodiment of the present application provides an auxiliary device for adjusting a breathing machine, which comprises Figure 1 As shown in the figure, the device comprises:

[0057] A running module 101 is configured to run the breathing machine according to an inputted working parameter value of the breathing machine and a running instruction; the breathing machine is connected to a patient to assist the patient in breathing;

[0058] A first acquisition module 102 is configured to acquire a blood flow parameter value of the patient after the breathing machine is run and display the blood flow parameter value;

[0059] A determination module 103 is configured to determine a relationship between the blood flow parameter value and a preset blood flow parameter range according to the acquired blood flow parameter value and the preset blood flow parameter range and display the relationship for reference of adjusting the breathing machine.

[0060] It can be understood that the breathing machine can artificially replace or partially replace the autonomous breathing of the patient, improve the breathing efficiency of the patient, and further improve the vital signs of the patient. Moreover, from the medical point of view, the relationship between breathing and blood circulation is very close, therefore, the running of the breathing machine can also affect the blood flow parameter value. Therefore, by acquiring the blood flow parameter value and the relationship between the blood flow parameter value and the blood flow parameter range, for example, the difference or ratio between the two, and then adjusting the breathing machine according to the relationship, the function of precisely adjusting the breathing machine can be achieved.

[0061] It can be understood that adjusting the breathing machine means adjusting the working parameters of the breathing machine. The main parameters of the breathing machine are briefly introduced as follows.

[0062] 1. Breathing frequency: 8-18 times per minute, generally 12 times per minute, except for patients with severe chronic obstructive pulmonary disease (COPD) and acute respiratory distress syndrome (ARDS).

[0063] 2. Tidal volume (TV): 8-15 ml / kg of body weight, which is appropriately adjusted according to the clinical and blood gas analysis results.

[0064] 3. Inspiratory / Expiratory ratio: The inspiratory time is generally set to 1, and the inspiratory / expiratory ratio is preferably 1:2-2.5, the ratio is 1:1-1.5 for patients with restrictive diseases, the ratio is 1:1.5 for patients with heart dysfunction, and the ratio is 1.5-2:1 for patients with ARDS (at this time, the breathing is inverse, and the expiratory time is set to 1).

[0065] 4. Inspiratory flow rate (Flow): The flow rate of an adult is generally 30-70 ml / min. The flow rate can be reduced when the patient is quiet and falls asleep; the flow rate needs to be increased when the patient is feverish, agitated, convulsing and the like.

[0066] 5. Inhaled oxygen concentration (FiO2, Fraction of inspiration O2): For prolonged oxygen inhalation, it should generally not exceed 50%-60%.

[0067] 6. Trigger sensitivity adjustment: Usually 0.098-0.294 kPa (1-3 cmH2O), adjusted according to the patient's spontaneous inspiratory strength. Flow rate trigger is 3-6 L / min.

[0068] 7. Inspiratory pause time: generally 0-0.6s, not exceeding 1s.

[0069] 8. PEEP Adjustment: When FiO2 > 60% and oxygen partial pressure (PaO2) < 8.00 kPa (60 cmH2O), PEEP should be set from the perspective of benefiting the patient. Clinically, the commonly used PEEP value is 0.29–1.18 kPa (3–12 cmH2O), and rarely exceeds 1.47 kPa (15 cmH2O).

[0070] 9. Alarm Parameter Adjustment: Different ventilators have different alarm parameters. Adjustments should be made according to the principle of both safety and quiet operation. Pressure Alarm: Primarily used to monitor the patient's airway pressure. Generally, the high pressure limit is set at 0.49-0.98 kPa (5-10 cmH2O) above the normal airway high pressure (peak pressure), and the low pressure limit is set at the lowest pressure level that can maintain inspiration. FiO2: Generally, it can be 10%-20% higher or lower than the actual set FiO2. Tidal Volume: High-level alarm settings are the same as the set TV and mechanical ventilation (MV); low-level alarm limits are based on the lowest TV and MV levels that can sustain the patient's life. PEEP or Continuous Positive Airway Pressure (CPAP) Alarm: Generally based on the applied PEEP or CPAP level.

[0071] In the aforementioned operating module 101, the input of the ventilator's operating parameters or operating commands can be from a human user, such as a medical worker, or from other intelligent devices or intelligent modules set within the ventilator itself. The ventilator's operating parameters input before operation can be set solely based on the patient's condition, or the patient's blood flow parameter values ​​can be obtained before the ventilator starts operating. After the ventilator is running, it is recommended that adjustments to the operating parameters be made with reference to the patient's blood flow parameter values.

[0072] In the first acquisition module 102 described above, the acquired blood flow parameter values ​​of the patient can be values ​​after the blood flow parameter values ​​have stabilized. For example, blood flow parameter values ​​acquired after the ventilator has been running for a preset time, or values ​​after the fluctuation range of the blood flow parameter values ​​has been relatively fixed. The preset time can be the time when the ventilator takes effect, which is generally determined clinically by medical professionals. The blood flow parameter values ​​can be displayed on the ventilator's operating interface or on another display interface, without limitation.

[0073] In the determination module 103, the preset blood flow parameter range can be a clinical medical standard or a parameter range set by medical workers according to the patient condition. The relationship between the obtained blood flow parameter value and the blood flow parameter range can be displayed together with the blood flow parameter value or separately. The relationship between the obtained blood flow parameter value and the blood flow parameter range can be the difference between the two values, a proportional relationship between the two values, or other numerical relationships that are helpful for ventilator adjustment, which will not be listed here.

[0074] In some embodiments, the running module 101 is specifically used for:

[0075] The setting value of the positive end-expiratory pressure (PEEP) input by the operator through the input component is obtained.

[0076] The operator can be a medical worker. PEEP is an important parameter in the setting of a mechanical ventilation ventilator, and the setting of PEEP is affected by many factors, and is also closely related to the blood flow parameter. Therefore, PEEP needs to be explicitly set before running, and also needs to be adjusted in time after running. It can be understood that the working parameter value of the ventilator input by the running module 101 can also include other working parameters.

[0077] In some embodiments, the first acquisition module 102 is specifically used for:

[0078] The blood flow parameter value measured by the blood flow dynamic measurement component in the ventilator is obtained.

[0079] Alternatively, the blood flow parameter value measured by the blood flow dynamic measurement device is obtained through a communication connection intermediary.

[0080] That is, the blood flow parameter value can be measured by the blood flow dynamic measurement component provided in the ventilator, or measured by the blood flow dynamic measurement device independent of the ventilator and transmitted to the ventilator through a communication connection intermediary. The communication connection intermediary can be a connection intermediary for communication between two devices through a communication protocol, which can be a wired intermediary such as Ethernet / Serial Interface / Universal Serial Bus (USB), etc.; or a wireless intermediary such as a mobile hotspot (Wi-Fi) / bluetooth, etc.

[0081] In some embodiments, the first acquisition module 102 is specifically used for:

[0082] acquiring a velocity-time integral (VTI), a cardiac output (CO), a blood oxygen saturation SPO2, an oxygen delivery (DO2), a jugular vein index (JVI) and a jugular vein morphology of the patient.

[0083] It can be appreciated that the VTI, the CO, the SPO2, the DO2, the JVI and the jugular vein morphology are all blood flow parameters closely related to the operation of the ventilator. It can be appreciated that the first acquiring module 102 can also be configured to acquire other blood flow parameters.

[0084] In some embodiments, the first acquiring module 102 can also be configured to:

[0085] acquiring a fluctuation of the waveform of the jugular vein in the systole and diastole.

[0086] From a medical point of view, if the patient has abnormal respiration, the fluctuation amplitude of the waveform of the jugular vein is usually increased. Therefore, the fluctuation of the waveform of the jugular vein in the systole and diastole is needed to be acquired to better adjust the ventilator. The waveform of the jugular vein includes the waveform in the systole and the waveform in the diastole.

[0087] In some embodiments, as shown in Figure 2 The apparatus can further include:

[0088] a second acquiring module 104 configured to acquire a preset blood flow parameter range input by an operator through an input component.

[0089] It can be appreciated that the blood flow parameter range can be input before each operation of the ventilator to better target a specific patient. It can be appreciated that the blood flow parameter range input can also be directly used before the operation, i.e., the blood flow parameter range input can be stored in the ventilator.

[0090] In some embodiments, as shown in Figure 2 The apparatus can further include:

[0091] a recording module 105 configured to record working parameter data of the ventilator and blood flow parameter data of the patient after the operation or adjustment of the ventilator.

[0092] It can be appreciated that the recorded working parameter data of the ventilator and the blood flow parameter data of the patient can be values after the blood flow parameter values are relatively stable. The recorded working parameter data of the ventilator and the blood flow parameter data of the patient can be used for summarization and analysis to better understand the correlation between the working parameter of the ventilator and the blood flow parameter of the patient.

[0093] To further understand the auxiliary device for ventilator adjustment of the embodiments of the present application, the working process of the device is introduced as follows. As shown in Figure 3 , the working process includes:

[0094] Step 301: Start. Enter the ventilator setting interface. Through the setting interface, the user can input the working parameters of the ventilator, such as PEEP, and the device acquires; or the user can input the blood flow parameter range of the patient, and the device acquires.

[0095] Step 302: Acquire the preset blood flow parameter range. That is, the operator inputs the preset blood flow parameter range through the ventilator setting interface, and the device acquires.

[0096] Step 303: Acquire the working parameters of the ventilator. That is, the operator inputs the working parameters of the ventilator through the ventilator setting interface, and the device acquires.

[0097] Step 304: Acquire the blood flow parameter value of the patient. After the ventilator is running, the blood flow parameter value of the patient is measured and acquired through the blood flow force measuring component. The blood flow parameter can include VTI, CO, SPO2, DO2, JVI and jugular vein morphology. The blood flow force measuring component can be a component arranged in the ventilator, or a blood flow force measuring device independent of the ventilator. The acquired blood flow parameter value can be sent to the display interface of the ventilator for display, see Figure 4 . The JVI blood flow morphology in Figure 4 is the jugular vein blood flow morphology (the same below). The upper curve in the right curve in Figure 4 is the blood flow morphology of the carotid artery, and the lower curve is the jugular vein blood flow morphology.

[0098] Step 305: Is the blood flow parameter value stable? If yes, proceed to step 306, otherwise, return to step 304.

[0099] Step 306: Record data. Record the current stable ventilator working parameter data and the blood flow parameter data of the patient. The recorded data can be seen in Table 1.

[0100] PEEP 0 5 10 15 20 Ventilator parameter 2 20 25 30 35 40 VTI 40 38 30 28 25 CO 6.0 5.8 4.7 4.3 4.0 SPO2 80％ 85％ 90％ 94％ 95％ DO2 964 990 850 812 764 JVI 1.25 1.89 2.29 3.5 4.3 JV blood flow pattern S&D s&D D d d

[0101] Table 1

[0102] Step 307: Is the blood flow parameter value in line with the clinical requirements? If yes, proceed to step 308, otherwise, return to step 303. Generally, if the blood flow parameter value is in line with the clinical requirements, it means that the working parameters of the ventilator are relatively reasonable, and thus the execution can continue; otherwise, it can be necessary to adjust again, i.e. return to step 303. Understandably, the clinical requirements of the blood flow parameter here can be a standard set according to the specific condition of the patient.

[0103] Step 308: aggregate all data of the ventilator operation so far. That is, each recorded stable blood flow parameter value and corresponding ventilator working parameter, and also including the derived parameters calculated on the basis of blood flow parameter values, namely the graphs made, such as the trend curve of each blood flow parameter, the characteristics of jugular vein shape, etc. Among them, the trend curve of each blood flow parameter can be seen in Figure 5 .

[0104] Specifically, the characteristics of the jugular vein shape can be calculated on the basis of Figure 6 and Figure 7 . The following will briefly introduce the calculation purpose and process:

[0105] As shown in Figure 6 , the jugular vein includes the S segment waveform of systolic blood flow and the D segment waveform of diastolic blood flow. In a normal state, the S segment and D segment waveforms of the human body are close to a gentle straight line, or only have small fluctuations. But in a diseased state, the S segment and D segment waveforms will appear excessive fluctuations. For example, right atrioventricular valve stenosis and insufficiency, pulmonary hypertension, pulmonary stenosis, congenital heart disease atrial septal defect, Fallot's triad and Ebstein's anomaly, etc. may cause excessive fluctuations of S segment and D segment waveforms. Further, when using a ventilator, the lung pressure is affected by the ventilator, which will cause abnormal venous blood flow waveform. Therefore, when adjusting the working parameters of the ventilator, the S segment and D segment waveforms are reduced as much as possible to reduce the right atrial pressure.

[0106] Further, in order to more accurately describe the characteristics of the jugular vein shape, the jugular vein flow graph in Figure 6 can be segmented, and the VTI and the characteristics of each part of the waveform are obtained, specifically as follows:

[0107] Figure 7 is a schematic diagram of waveform division of part of the waveform in Figure 6 . As shown in Figure 7 , the part of the waveform is obtained by segmenting an S segment waveform of systolic blood flow and a D segment waveform of diastolic blood flow from the jugular vein flow graph. Then the segmented waveform is divided into a base part B and a fluctuation part, and the fluctuation part is divided into S part and D part, which correspond to systole and diastole respectively. The height of the waveform is the depth of the blood flow waveform in the graph, denoted by V, which is Vs, Vd and Vb respectively. Figure 7 VTI in .

[0108] I) Calculate VTI.

[0109] VTI is the velocity-time integral of blood flow, which is an important indicator among blood flow parameters. Generally, one VTI is calculated per beat. According to the related art in the field, it is known that:

[0110] VTI-B = VTI-BS + VTI-BD (1)

[0111] VTI = VTI-B + VTI-S + VTI-D (2)

[0112] wherein: VTI-B: VTI value of the base part B in the waveform;

[0113] VTI-S: VTI value of the S part in the waveform;

[0114] VTI-D: VTI value of the D part in the waveform;

[0115] VTI-BS: VTI value of the base part B in the systole;

[0116] VTI-BD: VTI value of the base part B in the diastole.

[0117] II) Discrimination of jugular vein morphology:

[0118] 1) Definition of S:

[0119] Large S: there is S waveform, and the waveform is high;

[0120] Small s: there is S waveform;

[0121] No s: there is no S waveform.

[0122] 2) Definition of D:

[0123] Large D: there is D waveform, and the waveform is high;

[0126] 3) Discrimination of S:

[0128] When k2*Vb ≤ Vs ≤ k1*Vb, it is small s, wherein k1, k2 are coefficients, and the optional range is k1 > 1.5, 1.5 ≥ k2 ≥ 1.1.

[0129] When Vs < k2*Vb, there is no S waveform.

[0130] Or:

[0131] When k1*VTI-BS < VTI-S, it is large S, wherein k1 is a coefficient, and the optional range is k1 > 0.5.

[0132] When k2*VTI-BS≤VTI-S≤k1*VTI-BS, for small s, wherein k1, k2 are coefficients, and optionally, k1>0.5, 0.5≥k2≥0.2.

[0133] When VTI-S<k2*VTI-BS, no S waveform.

[0134] 4) Discrimination of D:

[0135] When m1*Vb<Vd, for large D, wherein m1 is a coefficient, and optionally, m1>1.3.

[0136] When m2*Vb≤Vd≤m1*Vb, for small d, wherein m1, m2 are coefficients, and optionally, m1>1.3, 1.3≥m2≥1.1.

[0137] When Vd<m2*Vb, no D waveform.

[0138] Or:

[0139] When m1*VTI-BD<VTI-D, for large D, wherein m1 is a coefficient, and optionally, m1>0.3.

[0140] When m2*VTI-BD≤VTI-D≤m1*VTI-BD, for small d, wherein m1, m2 are coefficients, and optionally, m1>0.3, 0.3≥m2≥0.1.

[0141] When VTI-D<m2*VTI-BD, no D waveform.

[0142] Step 309: End. Continue running the ventilator, but the blood flow parameter value acquisition and the like can be stopped.

[0143] The modules included in the embodiment can be implemented by a processor in a computer; of course, they can also be implemented by a logic circuit in the computer; in the implementation process, the processor can be a general-purpose processor, a digital signal processor (DSP), a field programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. Among them, the general-purpose processor can be a central processing unit (CPU), a microprocessor (MPU), or any other conventional processor.
