Lung ventilator expiratory air purifying processing deviceTechnical field
The utility model is Medical Devices, is mounted in the processing unit on lung ventilator, specifically a kind of lung ventilator exhalationGas purification treating device.
Background technology
Many patients are needed to use in lung ventilator, the gas that patient is breathed out when using lung ventilator containing substantial amounts of in hospitalMoisture, bacterium, impurity, these exhalation things belong to harmful substance, and patient breathes out from lung ventilator when in use for current lung ventilatorThese harmful substances have been vented directly in air, and pollution is caused to ward, easily cause medical worker and surrounding populationCross-infection, when also one problem is that the gas containing moisture, bacterium, impurity breathed out is passed through inside lung ventilator in addition, meetingThe part damaged inside lung ventilator, reduces the service life of lung ventilator.
The content of the invention
The purpose of this utility model is to provide a kind of lung ventilator exhaled gas purifying processing device, it is to avoid the hair of above mentioned problemRaw, the gas for making patient be breathed out through lung ventilator is nontoxic, harmless, it is ensured that the health and safety of medical worker and surrounding population.
What the utility model was realized in：Including gaseous mass analysis module, signal transmission line, exhaled gas detectionDevice, exhaled gas efferent duct, biofilter, exhaled gas input pipe, absorber, box body, base, cross over pipe, box body are installedOn base, biofilter, absorber are arranged in inner box, by cross over pipe UNICOM between biofilter and absorber,Installed on biofilter and exhaled gas input pipe is installed on exhaled gas efferent duct, absorber, gaseous mass analysis module peaceOn the lateral surface of box body, in expiratory air detector insertion exhaled gas efferent duct, one end of signal transmission line, which is connected to, exhalesOn outlet detector, the other end of signal transmission line is connected in gaseous mass analysis module, exhaled gas efferent duct, expiratory airBody input pipe is stretched out outside box body.
The beneficial effects of the utility model are：The utility model is arranged on the exhalation pipeline on breathing tubes of breathing machine road, patientThe gas of exhalation has to pass through the utility model, when the gas of patient's exhalation passes through absorber, impurity and moisture in gas etc.It is adsorbed, then during to biofilter, the bacterium in gas is filtered out, and makes to obtain only from the gas that exhaled gas efferent duct flows outChange, the gas discharged is nontoxic, harmless, it can be ensured that the health and safety of medical worker and surrounding population, therefore, the utility modelPurpose of design can be reached, with significant social benefit.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Embodiment
Embodiment of the present utility model is described further with reference to Fig. 1.
As shown in Figure 1, implementation of the present utility model includes gaseous mass analysis module 1, signal transmission line 2, expiratory air inspectionSurvey device 3, exhaled gas efferent duct 4, biofilter 5, exhaled gas input pipe 6, absorber 7, box body 8, base 9, cross over pipe10, box body 8 is arranged on base 9, and biofilter 5, absorber 7 are arranged in inner box 8, biofilter 5 and absorber 7Between be connected by the UNICOM of cross over pipe 10, biofilter 5 with exhaled gas efferent duct 4, absorber 7 and exhaled gas input pipe 6Connection, gaseous mass analysis module 1 is arranged on the lateral surface of box body 8, the insertion exhaled gas of expiratory air detector 3 efferent duct 4In, one end of signal transmission line 2 is connected on expiratory air detector 3, and the other end of signal transmission line 2 is connected to gaseous mass pointAnalyse in module 1, exhaled gas efferent duct 4, exhaled gas input pipe 6 are stretched out outside box body 8, it is connected to exhaling for lung ventilatorIn the exhalation pipeline on suction pipe road.
When the gas of patient's exhalation passes through expiratory air detector 3, the composition and processing data of the gas of exhalation can be detected,The data display detected can be come out by gaseous mass analysis module 1, and relevant data storage to gaseous mass is dividedAnalyse on the data storage disk in module 1, so that the gas to discharge is analyzed and is assessed.
