[0034] like Figure 1 , Figure 2 and Figure 5As shown, in an embodiment of the present application, a multifunctional cardiopulmonary resuscitation machine quality control detection device includes a pressing module, a gas monitoring module, a measurement and control module and a power module 5. Among them, the pressing module includes a pressing platform 1, an elastic member 12, a guide bracket 4 and a displacement sensor 10. The pressing platform 1 is slidably connected to the guide bracket 4, and the pressing platform 1 can move in the vertical direction relative to the guide bracket 4. The elastic member 12 is used to simulate the automatic rebound of the human chest cavity, and the elastic member 12 is installed between the guide bracket 4 and the pressing platform 1. The displacement sensor 10 is used to collect the pressing depth of the pressing platform 1. The gas monitoring module includes a pipeline 9 and a two-way gas flowmeter 11, wherein the two-way gas flowmeter 11 is used to detect the gas flow information in the pipeline 9 when the gas is input into the pipeline 9. The measurement and control module includes a control unit 8 and a display module 2, wherein the control unit 8 is respectively connected to the display module 2, the displacement sensor 10 and the two-way gas flowmeter 11. The control unit 8 calculates the compression depth and / or compression frequency of the compression platform 1 according to the data collected by the displacement sensor 10, and detects the actual blowing frequency and / or actual tidal volume of the tested cardiopulmonary resuscitation machine according to the data detected by the two-way gas flow meter 11, and sends them to the display module 2 for display.

[0035] The multifunctional cardiopulmonary resuscitation machine quality control detection device is provided with a pressing module, so it can test the load capacity, no-load capacity and pressing frequency of the cardiopulmonary resuscitation machine under test. In addition, the multifunctional cardiopulmonary resuscitation machine quality control detection device is also provided with a gas monitoring module, so it can detect the working blowing frequency and working tidal volume of the cardiopulmonary resuscitation machine under test.

[0036] The “ / ” in the embodiments of the present application means “or”.

[0037] like Figure 2 and Figure 5 As shown, in a possible embodiment, the gas monitoring module also includes a pressure sensor 6, which is used to detect the gas pressure information in the pipeline 9 when the gas is input into the pipeline 9. Among them, the pressure sensor 6 is connected to the control unit 8 and the power module 5 respectively, and the control unit 8 detects the blowing pressure of the cardiopulmonary resuscitation machine under test according to the data detected by the pressure sensor 6. The power module 5 supplies power to the pressure sensor 6. An airway pressure interface is reserved on the pipeline 9, and the pressure sensor 6 is installed on the pipeline 9 through the airway pressure interface, and its airtightness is ensured to be good. After the monitoring starts, the airway pressure waveform will be displayed in real time on the display module 2, and the calibrator can adjust the ventilation pressure setting of the cardiopulmonary resuscitation machine under test according to the waveform.

[0038] like Figure 3As shown, in a possible embodiment, the pressing platform 1 is provided with a first guide portion 1a extending downward. The guide bracket 4 is provided with a second guide portion 4a extending upward. The pressing platform 1 is slidably connected with the second guide portion 4a of the guide bracket 4 through the first guide portion 1a. When the pressing platform 1 is pressed by the weight 13 or the pump head of the cardiopulmonary resuscitation machine, the downward movement of the pressing platform 1 and the upward reset process of the pressing platform 1 under the elastic force of the elastic member 12 are guided by the cooperation of the first guide portion 1a and the second guide portion 4a.

[0039] like Figure 3 As shown, in a possible embodiment, at least one guide protrusion 1c extending along its axial direction is provided on the outer surface of the first guide portion 1a, and a guide groove 4b corresponding to and matching the guide protrusion 1c is provided on the inner wall of the second guide portion 4a. When the up and down movement of the pressing platform 1 is guided only by the first guide portion 1a and the second guide portion 4a, the pressing platform 1 may have the problem of rotating around its axial direction during the movement. In order to solve this problem, a guide protrusion 1c and a guide groove 4b are further provided, and the rotation problem is solved by the cooperation of the guide protrusion 1c and the guide groove 4b.

[0040] like Figure 3 As shown, in a possible embodiment, the first guide portion 1a is provided with a guide protrusion 1c whose cross section is square. The cross section of the guide protrusion 1 is designed to be square, and its anti-rotation effect is better.

[0041] like Figure 1 and Figure 2 As shown, in a possible embodiment, a multifunctional cardiopulmonary resuscitation machine quality control detection device further includes a housing 3, wherein the pressing module, the gas monitoring module, and the control unit 8 of the measurement and control module are all arranged in the housing 3, and the display module 2 is arranged on the housing 3. A pressing avoidance hole 3a is opened on the upper surface of the housing 3 at a position corresponding to the pressing platform 1.

[0042] like Figure 1 and Figure 2 As shown, in a possible embodiment, one side of the upper surface of the housing 3 is tilted downward to form an inclined surface 3b, and the display module 2 is arranged on the inclined surface 3b. The display module 2 is arranged on the inclined surface 3b to facilitate operation and reading by operators.

[0043] like Figure 4As shown, in a possible embodiment, a tray 14 is further included, and a pressing portion 14a extending downward is provided on the tray 14. When checking the load capacity of the cardiopulmonary resuscitation machine, it is generally necessary to use a weight with a mass of 30kg to 50kg, and the weight of 30kg to 50kg has the characteristic of large volume, so it is necessary to set a sufficiently large bearing surface for it, which will cause the volume of the entire device to be larger. In order to avoid this problem, by adding a tray 14, when using this multifunctional cardiopulmonary resuscitation machine quality control detection device to test the load capacity of the cardiopulmonary resuscitation machine, the tray 14 is placed on the pressing platform 1, and when not in use, the tray 14 can be removed.

[0044] like Figure 4 As shown, if the tray 14 is directly placed on the pressing platform 1, the weight 13 and the tray 14 may slide down together, so there is a safety hazard. In order to solve this problem, a mounting hole (not shown in the figure) for connecting with the pressing platform 1 is provided at the bottom of the pressing portion 14a. A fixing bolt hole 1b is provided in the middle of the pressing platform 1 at a position corresponding to the mounting hole. The tray 14 can be fixedly connected to the pressing platform 1 by bolts 15 through the mounting hole and the fixing bolt hole 1b.

[0045] like Figure 2 As shown, in a possible embodiment, the elastic member 12 is a cylindrical spring. The cylindrical spring is used to simulate the rebound force of the chest, which is more in line with the actual situation during the cardiopulmonary resuscitation compression process and improves the accuracy of the detection.

[0046] In a possible embodiment, the displacement sensor 10 is a laser displacement transmitter. The display module 2 is a touch display screen.

[0047] In a possible embodiment, the control unit 8 adopts a PLC control unit, which is integrated with an analog-to-digital conversion subunit, and the analog-to-digital conversion subunit is used to convert the analog signals collected by the displacement sensor 10, the bidirectional gas flow meter 11 and the pressure sensor 6 into digital signals.

[0048] The following uses three weights 13 with masses of 30kg, 40kg and 50kg as examples to describe the process of using the multifunctional cardiopulmonary resuscitation machine quality control detection device to detect the load capacity of the cardiopulmonary resuscitation machine as follows:

[0049] (1) Place the pressing portion 14 a of the tray 14 on the pressing platform 1 of the multifunctional cardiopulmonary resuscitation machine quality control and testing device, and use bolts 15 to fix the tray 14 to the pressing platform 1 .

[0050] (2) A weight 13 with a mass of 30 kg is selected and placed on the tray 14. At this time, the multifunctional cardiopulmonary resuscitation machine quality control detection device automatically calculates the first pressing depth corresponding to the 30 kg weight 13 and displays it through the display module 2. For the accuracy of the data, the same mass of the weight 13 can be tested several times again, and the first pressing depth obtained in each test can be recorded respectively. For example: at least three tests are performed for the 30 kg weight 13, and the first pressing depths of the three tests are recorded as 29.98 mm, 30.01 mm, and 30.05 mm.

[0051] (3) Remove the 30kg weight 13 and select a 40kg or 50kg weight for testing. The operation method is the same as that for the 30kg weight. After the test, remove the weight 13.

[0052] (4) Install the cardiopulmonary resuscitation machine, set the working compression depth on the cardiopulmonary resuscitation machine to be tested, for example, 29.98mm, operate the cardiopulmonary resuscitation machine quality control detection device and the cardiopulmonary resuscitation machine to start working, the cardiopulmonary resuscitation machine to be tested presses the compression platform 1 through the pump head, and the multifunctional cardiopulmonary resuscitation machine quality control detection device automatically calculates the second compression depth of the cardiopulmonary resuscitation machine to be tested and displays it through the display module 2. If the second compression depth is 29.80mm at this time, |29.80-29.98|≤0.5mm (0.5mm is the industry standard).

[0053] The working compression depth of the tested cardiopulmonary resuscitation machine is set to 30.01 mm, and the compression platform 1 is pressed by the pump head of the tested cardiopulmonary resuscitation machine. If the second compression depth is 30.20 mm at this time, |30.20-30.01|≤0.5 mm.

[0054] The working compression depth of the tested cardiopulmonary resuscitation machine is set to 30.05 mm, and the compression platform 1 is pressed by the pump head of the tested cardiopulmonary resuscitation machine. If the second compression depth is 30.25 mm at this time, |30.25-30.01|≤0.5 mm.

[0055] The above three test results all indicate that the load capacity of the cardiopulmonary resuscitation machine is sufficient to withstand 30kg of chest rebound force.

[0056] The test method for 40kg and 50kg weights is the same as that for 30kg weights.

[0057] If the compression depth difference between the second compression depth and the first compression depth difference obtained by testing with a 40k weight is not within the preset depth difference range, it means that the load capacity of the cardiopulmonary resuscitation machine is insufficient to bear the 40kg chest rebound force.

[0058] When the multifunctional cardiopulmonary resuscitation machine quality control and testing device is used to test the load capacity of the cardiopulmonary resuscitation machine, the elastic force of the elastic member 12 is between 30 kg and 50 kg.

[0059] The multifunctional cardiopulmonary resuscitation machine quality control detection device can also be used to test the no-load capacity of the cardiopulmonary resuscitation machine under test, specifically:

[0060] When conducting a no-load capacity test, the elastic member 12 only needs to satisfy the requirement that the pressing platform 1 can be reset after being pressed down. During the test, the pressing depth of the cardiopulmonary resuscitation machine under test is set, and the pressing platform 1 is pressed by the pump head of the cardiopulmonary resuscitation machine under test. The multifunctional cardiopulmonary resuscitation machine quality control detection device automatically calculates the second pressing depth of the cardiopulmonary resuscitation machine under test and displays it through the display module 2. If the difference between the set pressing depth and the second pressing depth is within the preset depth difference range, it means that the pressing depth of the cardiopulmonary resuscitation machine under test meets the requirements under no load, otherwise it means that the pressing depth under no load does not meet the requirements.

[0061] When the load capacity and no-load capacity of the cardiopulmonary resuscitation machine are tested, the compression frequency can also be calculated based on the analog voltage value output by the displacement sensor 10, and the actual blowing frequency and actual tidal volume can be calculated based on the data detected by the bidirectional gas flow meter 11, specifically:

[0062] (1) Before the test, the pipe 9 of the multifunctional cardiopulmonary resuscitation machine quality control detection device is connected to the gas source, and the cardiopulmonary resuscitation machine under test controls the gas source to input gas into the pipe 9 through the electromagnetic flow valve. The working blowing frequency, working tidal volume and working compression frequency also need to be set on the cardiopulmonary resuscitation machine under test.

[0063] (2) During the test, when the pressing platform 1 is pressed by the pump head of the cardiopulmonary resuscitation machine under test, the multifunctional cardiopulmonary resuscitation machine quality control detection device calculates the actual pressing frequency and actual pressing depth of the cardiopulmonary resuscitation machine under test based on the data detected by the displacement sensor 10, and calculates the actual blowing frequency and actual tidal volume based on the data detected by the bidirectional gas flow meter 11.

[0064] (3) Calculate the difference in compression frequency between the actual compression frequency and the working compression frequency. If the compression frequency difference is within the preset compression frequency difference range, it means that the compression frequency of the cardiopulmonary resuscitation machine under test meets the requirements; otherwise, it means that the compression frequency of the cardiopulmonary resuscitation machine under test does not meet the requirements. The preset compression frequency difference range is set according to industry standards. If the blowing frequency difference is within the preset blowing frequency difference range, it means that the blowing frequency of the cardiopulmonary resuscitation machine under test meets the requirements; otherwise, it means that the blowing frequency does not meet the requirements. If the tidal volume difference is within the preset tidal volume difference range, it means that the tidal volume of the cardiopulmonary resuscitation machine under test meets the requirements; otherwise, it means that the tidal volume does not meet the requirements.

[0065] During the entire test process, the multifunctional cardiopulmonary resuscitation machine quality control detection device can also detect the pressure data in the pipeline 9 through the pressure sensor 6 to detect the blowing pressure of the cardiopulmonary resuscitation machine under test.

[0066] In the embodiment of the present application, the measurement and control module compares the cumulative forward ventilation flow value of a single blow with the working tidal volume manually input by the user. After completing the entire measurement process, the tidal volume difference between the mean tidal volume (i.e., the actual tidal volume) and the working tidal volume is calculated and displayed on the display module.

[0067] In the embodiment of the present application, the measurement and control module calculates the pressing frequency according to the analog voltage value output by the displacement sensor 10. Within a certain metering period, the measurement and control module uses a step counting algorithm to count the number of times the voltage peak occurs and calculates the average pressing frequency: f1=N / T;

[0068] Wherein, f1 is the average pressing frequency (i.e., the actual pressing frequency), in Hz, N is the number of times the voltage peak occurs within T time, and T is the measurement cycle time.

[0069] In the embodiment of the present application, the measurement and control module records the time point when the gas flow rate is 0 through the zero point detection algorithm, and records the suction zero point t when the gas flow rate is higher than 10 sccm. I When the exhalation zero point is lower than -10 sccm, record t E By calculating the time of the entire exhalation and inhalation cycle, the actual blowing frequency of the cardiopulmonary resuscitation machine is obtained in real time: f2=1 / (t E -t I );

[0070] Among them, f2 is the actual blowing frequency of the cardiopulmonary resuscitation machine.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
