Description

[0001] APPARATUS AND METHOD FOR MEASURING INTERPLEURAL PRESSURE [0002]

The present invention relates to an apparatus and method for non-invasively measuring the pressure of the pleura, which is a pressure acting in the pleural cavity.

Pleural pressure is the pressure that acts on the lungs to stretch the lungs and enable breathing. Intrapleural pressure is defined as the pleural cavity surrounded by the visceral pleura surrounding the lung and the parietal plerua inside the rib, the mediastinal pleura around the mediastinum, and the diaphragm. ), And is maintained at a negative pressure of -10 cmH2O or less in a steady state. A pleural cavity is a volumetric, non-volatile space in which, with the lungs and ribs touching, a sliding movement is performed with the help of a small amount of pleural fluid. However, when the lungs are in a state of pneumothorax, empyema or hemothorax, air, agitation, or blood may accumulate in the pleural cavity, resulting in a change in pleural pressure.

In addition, if excessive pressure is applied to the pressure corresponding to the pressure of the pleura, spontaneous pneumothorax may occur or the work load may increase during respiration. In particular, if thoracic surgery is performed to remove the lungs, the volume of the lung to fill the thoracic cavity is reduced, and the degree of intrapleural negative pressure increases, resulting in continuous air leakage, dead space, Pneumothorax infection, and empyema may occur.

Therefore, the technique of measuring the pressure of the pleural fluid is necessary for the proper management of the patient after thoracic surgery and it is important to provide a clue to the understanding of the respiratory mechanics of the patient. Therefore, We need skills that can be done.

In the past, we tried to use an invasive method to measure the pleural cavity by inserting a probe. However, when a probe is placed in the pleural cavity of a normal person in a normal state to measure the pressure of the pleural fluid directly, the probe is inserted into the potential space of the bulky pleural cavity which is in contact with the lungs and ribs in a normal state. It could be done.

In addition, indirect methods of measuring pleural pressure through esophageal manometry have been used for a long time. However, because esophageal wall, mediastinal pleura, and blood vessels and connective tissues are located between esophagus and pleura, it is impossible to accurately measure pleural pressure by esophageal pressure. Therefore, there is no way to measure the normal pressure in the pleura.

Therefore, it is possible to measure the pressure inside the chest tube connected directly to the patient's lungs and to provide a non-invasive measurement value close to that of the pleural pressure. It is also possible to measure the pleural pressure of a patient with chest tube, A device for measuring pleural pressure, and a method for measuring the same.

Hereinafter, a device for measuring pleural pressure according to embodiments of the present invention and a method for measuring pleural pressure using the same will be described with reference to the drawings.

1 is an internal configuration diagram of an apparatus for measuring pressure of a pleural fluid according to an embodiment of the present invention.

Referring to FIG. 1, an apparatus 100 for measuring intra-pleural pressure according to an embodiment of the present invention includes a device connection unit 110; A pressure sensor unit 120; A control unit 130; And a display unit 140.

The device connection unit 110 serves to connect the device to the chest tube 200. The chest tube 200 corresponds to a tube inserted into the pleural cavity. The case where the chest tube 200 is inserted into the patient's chest may vary. For example, the chest tube 200 may be connected to evacuate air or fluid when the patient's lung is damaged and air or fluid enters (e.g., a pneumothorax or pleural effusion is present). It is necessary to discharge air or fluid due to the pain or difficulty in breathing caused by the air or fluid in the pleural cavity. If air, body fluids, blood, etc. accumulate in the pleural cavity, The chest tube 200 should be inserted. In addition, for example, a trauma patient may be inserted to observe bleeding symptoms that are delayed after a long time even if there is not a lot of blood in the trauma.

Since the chest tube 200 is directly connected to the pleura, the pressure of the chest tube 200 can be in accordance with or approximate to the pleural pressure required to determine the patient's lung condition. Accordingly, the device for measuring intrapleural pressure pressure 100 may connect the device connecting portion 110 to the chest tube 200 to measure the pressure of the chest tube 200 exposed to the outside. The device connection 110 may be connected to the chest tube 200, including various configurations. However, the device connection unit 110 is not limited to the embodiments described below, and may be formed in various configurations.

One embodiment of the device connection 110 includes an injection needle; And a connector tube. The injection needle may be inserted into the chest tube 200 by stabbing the chest tube 200. The connection pipe may serve to transfer pressure from the injection needle to the pressure sensor unit 120. The connector may be replaced with tubes of different lengths depending on the conditions of use. In addition, for example, when the device for measuring the internal pressure of the chest tube 200 is manufactured in a small size, the connection pipe extending from the housing of the pressure device 100 to the pressure sensor unit 120 without the connection pipe exposed to the outside, And the needle can be coupled to the housing.

The needle can be used as a disposable. That is, the connection tube may include an end shape that can detach and attach the disposable needles. Disposable needles can be used to prevent contaminants from entering the obstruction drainage system of the chest tube 200.

Another embodiment of the device connection 110 may include a three-way valve and a connector. The connection pipe may serve to transmit pressure from the three-way valve to the pressure sensor unit 120.

The three-way valve is a valve having fluid outlets in three directions, and may be installed or disposed in the middle of the chest tube 200. For example, the first chest tube 200 connected to the patient's lungs in the first direction and the second direction of the three-way valve may be connected to the second chest tube 200 connected to the drainage tank. The third direction of the three-way valve is normally blocked and can be opened by the user or automatically when the connecting pipe is connected.

In addition, the control unit 130 performs a function of controlling supply of power to each configuration in order to calculate the pleural pressure.

The result data calculated based on the pressure data by the controller 130 may include a maximum value, a minimum value, an average value, and the like. The resultant data may also include real-time measurements. For example, the control unit 130 may perform initialization at the start of measurement, and may calculate at least one of the maximum value, the minimum value, and the average value of the pressure data accumulated from the initial point of the measurement. Then, the control unit 130 may generate data (for example, a text, a graph, and the like) for displaying on the display unit 140 as result data together with the real-time measurement values.

In addition, the controller 130 may calculate the patient condition based on the resultant data. For example, the control unit 130 may calculate or predict a change in the lung state of the patient using the cumulative resultant data periodically measured.

The display unit 140 displays the result data generated by the controller 130. In addition, the display unit 140 displays (outputs) information (e.g., battery remaining amount, etc.) related to the pressure-sensitive device 100 to be provided to the user other than the result data (i.e., medical staff).

The external server may include a database server in the hospital for storing the result of measuring the pressure of the patient's pleural pressure.

When transmitted to the mobile terminal 300, the pressure data or result data may be stored in the mobile terminal 300 or transmitted to the external server through the mobile terminal 300.

When the external server receives the result data, the external server can accumulate the pleural pressure data of several patients. That is, the external server can match the patient's state at the time of the corresponding period and analyze the cumulative data to predict the state of the patient based on a specific patient's pleural pressure state.

The apparatus may further include an identification information obtaining unit. The identification information obtaining unit may perform the function of obtaining the patient identification information. For example, the identification information acquiring unit can recognize the barcode recognition module, and can read the barcode held by the patient to recognize the identification information of the patient. The identification information of the patient obtained through the identification information obtaining unit may be matched with the measured pressure of the patient's filtrate pressure data (i.e., result data), and the wireless communication unit may match the patient identification information with the result data, . Thus, the medical staff can distinguish the result data stored in the external server by the patient.
