Background technology
The lung ventilator of producing is carried out performance test, is the important step of maintaining strict control over gate of the quality monitoring, and at present, the simulated lung that domestic hospital adopts the rubber gloves after rubber gloves or the improvement to make mostly replaces people's lung that the lung ventilator performance is tested.Because the compliance of adult, child and baby's lung (i.e. the resistance that lung provides when ventilation) value is different, therefore use and with a kind of device lung ventilator is carried out performance test and easily cause measurement result to produce error, do not reach the purpose of test lung ventilator performance and quality good or not, in case clinically used this lung ventilator product off quality, can bring influence to patient's safety.In addition, the related data when at present the used simulated lung of domestic most of hospitals is to the lung ventilator performance test can not gather in real time, preserves and analyze, and can not draw testing result rapidly intuitively, influences work efficiency; Can not provide the data support for later research work, to work out better pertinent instruments.
The utility model content
The utility model discloses a kind of lung ventilator performance detecting system, overcome existing lung ventilator detection system, adopt rubber gloves to replace people's lung, cause test error big, product quality can not get effective guarantee, simultaneously the gained test data can not gather in real time, preservation and graphic presentation, can not provide drawbacks such as reliable theoretical analysis foundation for the research and the improvement of lung ventilator.The utility model not only can be at a high speed, accurately the lung ventilator performance is detected, and measured data in time can be shown, preserves, and detects the lung ventilator product fast and accurately and whether reach designing requirement.
A kind of lung ventilator performance detecting system, comprise simulated lung, temperature transmitter, data collecting card and PC, it is characterized in that: the simulated lung top connects an interface pedestal, and interface pedestal is provided with lung ventilator interface and sensor interface, and the lung ventilator interface is connected with lung ventilator by air shooter; Sensor interface connects pressure and temp one body sensor, pressure signal sends data collecting card to through data line, temperature signal sends temperature transmitter to through data line, sends data collecting card to by data line again after being converted to pressure signal, and data collecting card is connected with PC through data line.
Described simulated lung adopts vial, is provided with copper mesh in the vial.
Described interface pedestal and simulated lung are tightly connected, and lung ventilator interface and sensor interface that the interface pedestal top is provided with are tightly connected with air shooter, pressure and temp one sensor component respectively.
Computer operating system is Windows XP, and the used software of Data Management Analysis and graphic presentation is based on the independently developed collection analysis software of Visual C++6.0.Native system is by real time computer control, and control section is controlled by software-driven, gathers in real time and deal with data by system, and whether the analysis to measure data meet the requirements to judge the performance of lung ventilator.The data of gathering can be drawn in real time, by the graph direct analysis.
The utility model simple structure, easy to use, combine with acquisition system, can go out lung ventilator performance, quality quality according to the data express analysis of gathering, make things convenient for medical and nursing work person to use.Data can be preserved, and the data in real time of gathering can also be drawn, and make the user carry out intuitive analysis to data.Can be follow-up scientific research and education and offer help, for the more advanced instrument of research and development provides the data support.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
A kind of lung ventilator performance detecting system, as shown in Figure 1, comprise simulated lung 1, temperature transmitter 6, data collecting card 7 and PC 8, the top of simulated lung 1 connects an interface pedestal 3, interface pedestal 3 is provided with lung ventilator interface 4 and sensor interface 10, and lung ventilator interface 4 is connected with lung ventilator by air shooter; Sensor interface 10 connects pressure and temp one body sensor 5, pressure signal sends data collecting card 7 to through data line 9, temperature signal sends temperature transmitter 6 to through data line 9, send data collecting card 7 to by data line 9 again after being converted to pressure signal, data collecting card 7 is connected with PC 8 through data line.
Simulated lung 1 of the present utility model adopts vial, is provided with copper mesh 2 in the vial.
Described interface pedestal 3 is tightly connected with simulated lung 1, and lung ventilator interface 4 and sensor interface 10 that interface pedestal 3 tops are provided with are tightly connected with air shooter, pressure and temp one senser element respectively.
When lung ventilator is in running order, open user application interface, to select to gather button, whole acquisition system is promptly started working.The source of the gas turnover simulated lung that lung ventilator provides causes simulated lung internal pressure and variation of temperature.Pressure signal passes to data collecting card 7 through data line 9, and temperature signal passes to temperature transmitter 6 through data line 9 and is converted to pressure signal, passes to data collecting card 7 by data line 9 again.Analog signal conversion is a digital signal in capture card, reaches PC 8 through data line 9 then, carries out Data Management Analysis at PC, and whether judgment data is right with standard, and then draws lung ventilator performance quality.Meanwhile, also can be simultaneously under the application interface signal the gathered form with curve be reflected, data are carried out intuitive analysis.
Fig. 2 is system works flow process figure, lung ventilator is with after simulated lung links to each other, pressure in the simulated lung 1 that it exhales, all can make vial among Fig. 1 when air-breathing exerts an influence, make it to change, and these pressure variations promptly can be gathered by data collecting card 7 by pressure and temp one body sensor 5, reach PC by data line 9 then.In PC, the user can preserve, handle and analyze the data that collect by the user application of writing with VC++6.0 with preservation, processing and analysis data function.
Lung ventilator exhales for a long time, air-breathing and respiratory rate changes all can influence the stable of temperature in the vial, thereby influences the accuracy of compliance, and then instrument accuracy grade is exerted an influence.For avoiding when testing, producing this influence, insert copper mesh 2 in the device to keep the stable of bottle interior temperature.In the test, the temperature signal in the vial enters data collecting card by data line after temperature transmitter 6 conversions, reach PC then, carries out follow-up data processing and analysis by user application equally.
Adopt the vial of different volumes, the people's lung that can simulate different compliance values is applied to the lung ventilator performance of all ages and classes section with detection.
