Description
The present invention relates to an ultrasound system and a monitoring method for continuous monitoring of a lung state. More particularly, the present invention relates to an ultrasound system and a monitoring method for monitoring continuous pulmonary status of a lung by using a small ultrasonic probe, scoring gray scale images of lungs by ultrasound, To an ultrasonic system and a monitoring method for continuously monitoring the lung state.
In patients admitted to the ICU, the status of the lung is closely related to the survival rate, intensive care unit room length, and medical expenses, so it is important to observe and confirm the status of the lung. Ultrasonography is now becoming a basic tool for understanding cardiopulmonary status in the ICU. Echocardiography can be used to identify the condition of the heart and to confirm hemodynamic status. Pulmonary congestion, pneumothorax, acute respiratory distress syndrome (ARDS), etc., The importance of which is increasing, and its accuracy and reliability are intended to precede chest radiography.
Normal lungs signal A-line and lung sliding. However, pulmonary congestion or pulmonary ultrasound is a sign of the B-line, showing the echogenicity of the nodule as the interlobular septa becomes thicker due to edema of the lungs (Noble VE, Nelson B. Manual of Emergency and Critical Care Ultrasound. 2nd ed. Cambridge, England: Cambridge University Press; 2011)
Most of the signals observed in these ultrasonic waves depend on the operator. The same is true for B-line signals, and a method for measuring the degree of B-line directly in an ultrasonic machine has been studied. Brattain LJ, Telfer BA, Liteplo AS, Noble VE. Automated B-line scoring on thoracic sonography. J Ultrasound Med. Dec 31 (12): 2185-90. PubMed PMID: 24277902.)
In the initial study of pulmonary ultrasound, it was reported that a minimum of 12 pulmonary sites should be measured to determine the exact state of the lung. However, recent studies have shown that pulmonary ultrasound in confined areas does not have any problem in accurately measuring lung status (Brattain LJ, Telfer BA, Liteplo AS, Noble VE, Automated B-line scoring on thoracic sonography, J Ultrasound Med., 2013 Dec; 32 (12): 2185-90 PubMed PMID: 24277902.)
In addition, a scoring system was developed to quantify the degree of B-line showing pulmonary congestion in pulmonary ultrasound. The higher the score, the less prognosis the patient had (Santos TM, Franci D, Coutinho CMG, Ribeiro DL, Schweller M, Matos-Souza JR, et al. A simplified ultrasound-based edema score to assess lung injury and clinical severity in septic patients. Am J Emerg Med 2013; 31 (12): 1656-60 PubMed PMID: 24119611. PMCID: 24119611.)
However, in order to observe pulmonary congestion or pulmonary status by ultrasound, a large-sized ultrasonic machine should be brought to the side of the patient's bed, and in the case of the ICU, it may be difficult to perform in a narrow ICU space. In addition, although the pulmonary status of an ICU changes in real time, currently, pulmonary status is confirmed after a pulmonary ultrasound is taken only at a specific time. There is no system for monitoring the pulmonary status in real time, and the problem that the reading of ultrasound results varies depending on the skill of an observer have.
SUMMARY OF THE INVENTION The present invention has been made in order to solve all of the above problems, and it is an object of the present invention to transmit a gray scale image according to a B-line of a lung photographed by ultrasonic waves to a server in real time by attaching a small ultrasonic probe to the chest. And an ultrasonic system in which the server processes the image and scorens a score to the monitor in real time to continuously monitor the lung state.

It is also desirable to further include a software program embedded in the server for measuring and scaling the gray scale of the B-line of the pulmonary ultrasonic wave by the ultrasonic probe and calculating a change over a period of time.
The ultrasonic monitoring device and the server are preferably connected to each other by wireless or wire.
A method for continuously monitoring a lung state includes the steps of attaching an ultrasonic probe to a chest and emitting an ultrasonic wave to acquire a lung image; Confirming the presence of the B-line in the acquired lung image; Scoring a gray scale of the lung image when the B-line is present; And displaying the score by the scoring.
It is preferable that the ultrasonic emission and the display of the score are performed by an ultrasonic monitoring apparatus including a monitor.

In clinical medicine, it is expected that it will be an important starting point of research on personalization / automation of optimal treatment guidelines based on real - time lung condition in other fields besides ICU if it leads to clinical studies in the future.
In addition, it is possible to observe the pulmonary status non-invasively in real-time in a completely different way from the current monolithic treatment method in the treatment of an infected ICU, so that treatment according to the individual's lung condition becomes possible, , It is possible to establish new guidelines for the treatment of ICU and to lead internationally leading clinical studies.
In addition, from the socio-economic point of view, the industrial / economic impact is expected to be very large when considering the wide range of ICU market worldwide due to the ultrasonic system that continuously monitors the lung status.

When the ultrasonic probe is installed and positioned, the ultrasonic probe measures a gray scale at a depth of 3 to 5 cm and transmits a gray scale value to a monitor and analyzer body, Display.
Check for a sudden change in the score displayed on the monitor, and if there is no change, provide the monitor with a continuous display of the score to provide information about the state of the screen. If there is a change, operate the alarm system to determine whether the score is increasing or decreasing.
If there is a decrease in the score, check whether there is a pneumothorax or ultrasonic probe dropout, and if there is an increase in the score, judge whether the lung congestion or acute respiratory failure is progressing.
A method for continuously monitoring the pulmonary condition by the ultrasonic system of the present invention based on the peculiar monitoring algorithm is as follows.
First, an ultrasonic probe is attached to the chest, and ultrasound is emitted from the ultrasonic probe through an ultrasonic monitoring device to acquire a lung image.
Next, the presence of a B-line for judging the presence or absence of an abnormality in lung is confirmed from the obtained lung image.
Next, when the B-line exists, the gray scale of the lung image is scored by a software program built in the ultrasonic monitoring apparatus to calculate a certain score.
Next, the score calculated by the scoring is displayed on a monitor included in the ultrasonic monitoring device to check the status of the lung in real time.
As described above, the ultrasound system and the monitoring method for continuous monitoring of the lung state according to the present invention have been described with reference to the drawings. However, the present invention is not limited to the embodiments and the drawings disclosed herein, It is needless to say that various modifications can be made by those skilled in the art within the scope of the technical idea of the invention.
