Abstract
The invention belongs to the technical field of medical instruments and provides a sputum deposition online detecting system for mechanical ventilation patients. The system judges the sputum deposition degree according to airflow pressure and flow of mechanical ventilation and sputum gurgling sounds and has the warning function. The sputum deposition online detecting and warning system can replace medical workers for guarding wards, monitor the breathing airflow dynamic characteristic and the sputum gurgling sounds of the mechanical ventilation patients in real time, judge the sputum deposition degree through an intelligent algorithm, and provide reference for the medical workers to remotely diagnose the sputum deposition degree; in addition, according to the system, the warning upper limit of the sputum deposition degree can be set, and when the sputum deposition degree judged by the system exceeds the upper limit, the system automatically gives an alarm; the system is high in judgment precision, reduces the frequency for the medical workers to auscultate the sputum deposition degree of the mechanical ventilation patients when applied, reduces the workload of the medical workers, and has good popularization prospects.
Description
The invention belongs to technical field of medical instruments, relate to a kind of sputum online detection alarm system of depositing.
Background technology
Mechanical ventilation is the important means of clinical rescue and treatment patients with respiratory failure, is widely used in the first aid and intensive care unit(ICU) of various clinical departments.But, the artificial airway who sets up during mechanical ventilation, not only can stimulate secretion, inhibition ciliary movement, the alluvial of promotion sputum in respiratory tract of respiratory tract body of gland, and can cause ventilated patients " epiglottis " to lose physiological function, can not form the gas duct high pressure before cough, cannot discharge sputum by cough.
Sputum alluvial, in air flue, can make airway resistance increase, and causes hypoventilation, causes respiratory dysfunction, adds heavy patient's anoxia and carbon dioxide retention, and severe patient can stop up air flue threat to life because of expectorant crust; In addition, sputum stops up air flue, and antibacterial easily breeds, thereby causes patient to occur or increase the weight of pulmonary infection.
Therefore, clean unobstructed in order to maintain patient respiration road, prevention respiratory system infection, avoids respiratory tract injury, in time the expection situation of perception sputum.
For this situation, the sputum alluvial online monitoring alarm system that the present invention proposes can replace medical personnel, and the alluvial situation of Real-Time Monitoring patient sputum, for medical personnel take measures, for patient's expectorant provides reference, to have good promotion prospect in time.
Summary of the invention
The object of the invention is: a kind of sputum online detection alarm system of depositing is provided.
Technical scheme of the present invention is: native system is comprised of controller, display, button assembly, pressure transducer, flow transducer and sound transducer.Pressure transducer, flow transducer are for monitoring the Dynamic Characteristics of Gas Flow of patient's mechanical ventilation; Sound transducer is for monitoring patient's rale sound; Controller is mainly used according to the signal of pressure transducer, flow transducer, sound transducer, adopts intelligent algorithm, by calculating, draws the degree of sputum alluvial, and shows on display; Button assembly is mainly used in arranging the relevant parameter of this system.The sputum online detection alarm system of depositing comprises button assembly 1, controller 2, display 3, respirator interface 4, flow transducer 5, pressure transducer 6, sound transducer 7 and plays interface 8.(referring to Fig. 1).
Advantage of the present invention is: the sputum alluvial online monitoring alarm system that the present invention proposes can replace medical personnel, the alluvial situation of Real-Time Monitoring patient sputum, for medical personnel take measures to provide reference for patient's expectorant in time, the frequency that reduces medical personnel's auscultation patient sputum alluvial degree, has good promotion prospect.

The specific embodiment
Below the present invention is further illustrated.
Native system is connected in mechanical ventilation loop, and respirator interface is connected to respirator, and air flue interface is connected to patient airway.Respiratory air flow dynamic characteristic and rale sound that patient is deposited when slight without expectorant or sputum are set to reference value.During mechanical ventilation, Dynamic characteristic of flow, pressure dynamics and the rale sound of flow transducer 5, pressure transducer 6 and sound transducer 7 Real-Time Monitoring patient respiration air-flows, control is according to detecting Dynamic characteristic of flow, pressure dynamics and the rale sound obtaining, by comparing with reference value, adopt intelligent algorithm, judgement sputum alluvial degree, and showing screen display.
Claims (5)
1. the sputum online detection alarm system of depositing, is characterized in that: according to the patient respiration Dynamic Characteristics of Gas Flow of Real-Time Monitoring and rale sound, and by computing, judgement sputum alluvial degree, and there is warning function.
2. sputum according to claim 1 alluvial online monitoring alarm system, is characterized in that: by the patient respiration Dynamic Characteristics of Gas Flow that detects in real time and rale sound and the respiratory air flow dynamic characteristic and the rale sound that deposit without sputum alluvial or sputum when slight, contrast.
3. sputum alluvial online monitoring alarm system according to claim 1, is characterized in that: define a kind of sputum alluvial level index, according to patient respiration Dynamic Characteristics of Gas Flow and rale sound variation, by intelligent algorithm, determine the degree of patient's sputum alluvial.
4. sputum alluvial online monitoring alarm system according to claim 1, is characterized in that: adopt filtering technique to extract the feature sound spectrum of rale sound, in order to judge the degree of sputum alluvial.
5. sputum according to claim 2 alluvial online monitoring alarm system, is characterized in that sputum alluvial degree high alarm setting, when the sputum alluvial degree of system judgement has surpassed on this in limited time, and the spontaneous warning of system.
