Abstract
Description
Technical Field
[0001] The present invention relates to an intrathoracic pressure adjustment device and method. More specifically, it can measure and confirm the intrathoracic pressure in real time and at the same time adjust the intrathoracic pressure. Therefore, it relates to an intrathoracic pressure adjustment device and method that can be usefully used for measuring and adjusting the intrathoracic pressure and diagnosing pneumothorax.
Background Art
[0002] The thoracic cavity is the space between the parietal pleura and the visceral pleura that surrounds the lungs. The intrathoracic pressure means the pressure inside the thoracic cavity, and the pressure inside the thoracic cavity is generally slightly lower than the atmospheric pressure known as negative pressure.
[0003] Pneumothorax is a disease in which air fills the thoracic cavity surrounding the lungs, compressing the lungs and making normal breathing impossible, and symptoms such as dyspnea and chest pain appear. The exact cause of pneumothorax has not yet been elucidated, and there is no fundamental preventive method. Also, even in the young age group without lung diseases, it may develop for various reasons.
[0004] There are two types of pneumothorax. Closed pneumothorax (spontaneous pneumothorax) is caused by the rupture of the respiratory tract (trachea, bronchi, alveoli) allowing air to enter the thoracic cavity, and open pneumothorax (traumatic pneumothorax) is caused by air entering the thoracic cavity through a traumatic wound in the chest wall. Closed pneumothorax is more common.
[0005] The diagnosis of pneumothorax is currently performed by X-ray images, and characteristic air shadows appear in the images (photos) of chest X-ray examinations. In pneumothorax accompanied by more than 25% lung collapse, the breath sound weakens and disappears on auscultation. The size of the pneumothorax can be calculated by measuring the distance between the parietal pleura and the visceral pleura in a chest X-ray. In the case of a large or severe pneumothorax, a thin chest tube can be inserted into the thoracic cavity to perform a procedure to drain the air.
[0006] Since the diagnosis of pneumothorax by X-ray images is based on still images, it is difficult to determine whether air is leaking. Pneumothorax, which is a medical emergency, requires immediate surgery after diagnosis to relieve the patient's dyspnea and chest pain and prevent further damage.
[0007] Therefore, there is a need for a device and method that can be used for the diagnosis of pneumothorax and can measure and adjust the intrathoracic pressure in real time quickly and accurately.

Best Mode for Carrying Out the Invention
[0012] Hereinafter, the present invention will be described in detail with reference to the drawings.
[0013] Figure 1a is a diagram schematically showing the detailed configuration of an intrathoracic pressure adjustment device according to an embodiment of the present invention.
[0014] Referring to Figure 1a, an intrathoracic pressure adjustment device 10 according to an embodiment of the present invention may include an intrathoracic insertion part 11 disposed in the thorax, a pressure measurement part 12 for measuring the intrathoracic pressure, a display part 13 for displaying the measured data value, a control part 14 for generating the data value of the measured intrathoracic pressure, and an air discharge part 15 for discharging air from the thorax to the outside.
[0015] The intrathoracic insertion part 11 is disposed in the thorax. Specifically, the intrathoracic insertion part may include a syringe needle and / or a connecting tube. More specifically, the intrathoracic insertion part 11 is disposed in the thorax between the visceral pleura and the parietal pleura that wraps the outside of the lung by penetrating the parietal pleura in the body, and may include a detachable syringe needle and a connecting tube connected thereto.
[0016] As an example, the presence or absence of pneumothorax can be diagnosed by measuring the intrathoracic pressure using the intrathoracic pressure adjustment device 10 of the present invention. When the patient's lung is damaged and air or fluid has invaded (for example, when pneumothorax occurs or pleural effusion accumulates), air or fluid can be discharged through the device of the present invention.
[0017] The intrathoracic pressure adjustment device 10 of the present invention according to a preferred embodiment of the present invention can insert the syringe needle of the intrathoracic insertion part 11 into the thorax to measure the intrathoracic pressure. Further, the intrathoracic insertion part 11 may include various configurations, and may be formed in various configurations without being limited to the embodiments described below.
[0018] One embodiment of the thoracic insertion portion 11 may include a syringe needle and / or a connecting tube. The syringe needle can be inserted by piercing the chest cavity, and the connecting tube can be connected to the syringe needle of the thoracic insertion portion to transmit pressure to the pressure measurement unit, and tubes of different lengths may be used interchangeably according to the usage situation.
[0019] Also, for example, when the intrapleural pressure adjustment device 10 is manufactured in a small size, it may be present inside without an externally exposed connecting tube, and a syringe needle may be coupled to the housing of the intrapleural pressure adjustment device 10.
[0020] In one example, in order to prevent external contamination, the syringe needle may be disposable, and at this time, the connecting tube may include a detachable end form for the disposable syringe needle.
[0021] In the intrapleural pressure adjustment device of the present invention, the pressure measurement unit 12 may be characterized by measuring the intrapleural pressure. The pressure measurement unit 12 functions to measure pressure data. The pressure data may be the pressure data value in the chest cavity, and the pressure measurement unit 12 may measure the pressure transmitted by being connected to the thoracic insertion portion 11.
[0022] In the intrapleural pressure adjustment device of the present invention, the display unit 13 functions to display the result data generated by the control unit 14. Also, the display unit 13 displays (outputs) information related to the intrapleural pressure adjustment device 10 provided to the user (i.e., medical staff) other than the result data (for example, battery remaining amount, etc.).
[0023] In the intrathoracic pressure adjustment device of the present invention, the display unit 13 may include at least one of a liquid crystal display (LCD), a thin film transistor - liquid crystal display (TFT LCD), an organic light - emitting diode (OLED), a flexible display, a 3D display, and an e - ink display.
[0024] When the display unit 13 and the touch sensor form an interlayer structure (hereinafter referred to as a "touch screen"), the display unit 13 can be used not only as an output device but also as an input device.
[0025] In the intrathoracic pressure adjustment device of the present invention, the control unit 14 controls the overall operation of the intrathoracic pressure adjustment device 10. For example, the control unit 14 performs an information processing function of processing the pressure data received from the pressure measurement unit 12. The control unit 14 may generate result data based on the intrathoracic pressure data at the first measurement of the intrathoracic pressure by the pressure measurement unit 12, or the intrathoracic pressure data measured during the period from the first measurement to the time when air is discharged from the thoracic cavity to the outside through the air discharge unit. In addition, the control unit 14 performs a function of controlling to supply power to each component in order to calculate the intrathoracic pressure.
[0026] Further, the control unit 14 can control the discharge speed of the air discharged from the thoracic cavity to the outside through the air discharge unit 15 within a constant speed range, and can calculate the pressure data values and / or result data before and after the air discharge.
[0027] When the control unit 14 discharges air from the thoracic cavity to the outside through the air discharge unit 15, the discharge speed of the air discharged from the thoracic cavity to the outside through the air discharge unit 15 may be controlled within a certain speed range. For example, the air may be discharged from the thoracic cavity at a speed of 50 to 200 cc / min, specifically 85 to 200 cc / min, and more specifically 100 cc / min.
[0028] The result data calculated by the control unit 14 based on the pressure data may be calculated based on the intrathoracic pressure data at the first measurement of the intrathoracic pressure by the pressure measurement unit 12, or the intrathoracic pressure data measured during the period from the first measurement to the discharge of air from the thoracic cavity to the outside through the air discharge unit 15, and may include the maximum value, minimum value, average value, etc.
[0029] More specifically, the pressure data numerical value may include real-time measurement values. For example, the control unit 14 may perform initialization at the start of measurement and calculate based on the measured intrathoracic pressure data during the period from the first measurement to the discharge of air from the thoracic cavity through the air discharge unit 15. At this time, the pressure data value may be at least one or more of the maximum value, minimum value, and average value, but is not limited thereto.
[0030] Thereafter, the control unit 14 may generate data (such as text representing numerical values, graphs, etc.) for displaying the pressure data value and / or the result data on the display unit 13.
[0031] The air discharge unit 15 may be connected to the control unit 14 and discharge air from the thoracic cavity. At this time, the discharge direction of the air may be characterized by being in one direction from the thoracic cavity to the outside. At this time, the discharge speed of the discharged air may be controlled via the control unit 14.
[0032] In one embodiment, when using the intrathoracic pressure adjustment device 10 of the present invention, the intrathoracic pressure can be measured in real time, and the intrathoracic pressure data corresponding to air leakage that requires the insertion of a chest tube or a surgical incision can be calculated in real time, and then it can be determined whether further treatment such as chest tube insertion treatment or surgical treatment is necessary.
[0033] Also, by periodically measuring the above-mentioned result data, the change in the patient's lung condition can be calculated or predicted using the accumulated result data.
[0034] FIG. 1b is a diagram schematically showing the configuration of an intrathoracic pressure adjustment device according to another embodiment of the present invention.
[0035] Referring to FIGS. 1a and 1b, the intrathoracic pressure adjustment device 10 according to an embodiment of the present invention includes an intrathoracic insertion part 11; a pressure measurement part 12; a display part 13 for displaying the measured data value; a control part 14 for generating the measured intrathoracic pressure data value; and / or an air discharge part 15 for discharging air from the inside of the chest cavity to the outside. These may be connected by a tube-shaped connecting pipe, and a filter (not shown) for preventing backflow during air discharge and preventing the discharge of impurities other than air to the outside may be provided on the connecting pipe.
[0036] The filter may include, but is not limited to, a container for storing blood or body fluid when discharging it, a check valve for discharging air only in one direction from the inside of the chest cavity to the outside and preventing external air from flowing into the lungs, and / or an air filter for allowing only air to pass through. At this time, the filter is for the purpose of sterilization by gas filtration, can filter a small amount of organic solvent, and can remove solid-phase particles in the gas phase.
[0037] Also, in one embodiment, when the connecting tube is tubular, it may include a T-shaped connecting tube (T connector). The shape of the T-shaped connecting tube is an example and can be deformed into various shapes according to usage examples. The connecting tube can be used without limitation as long as it has an inlet / outlet in three directions and may be installed or arranged in the middle of the connecting tube. For example, the first direction of the T-shaped connecting tube may be connected to a tube connected to an injection needle inserted into the lung, the second direction may be connected to a pressure measuring unit, a control unit, and / or a display unit, and the third direction may be connected to a tube included in the air discharge unit, but it is not limited thereto and may include various modification examples. At this time, the air discharge unit may further include a pump for air discharge and a tube for air discharge in addition to the tube connected to the third direction. The air discharge pump may be connected to the tube connected to the third direction and / or a tube for discharging air to the outside.
[0038] When using the T-shaped connecting tube, a backflow preventer and / or an air filter may be present between the T-shaped connecting tube connected to the thoracic cavity insertion part (the first direction), and a backflow preventer and / or an air filter may be present between the T-shaped connecting tube connected to the air discharge part (the third direction). The backflow preventer and / or the air filter may be present respectively or simultaneously between the T-shaped connecting tube connected to the thoracic cavity insertion part (the first direction) and between the T-shaped connecting tube connected to the air discharge part (the third direction).
[0039] When a backflow preventer and / or an air filter is present between the T-shaped connecting tube connected to the thoracic cavity insertion part (the first direction), when air is discharged from the thoracic cavity, impurities other than air are filtered, and it can be prevented that impurities other than air reach the pressure measuring unit, the display unit, and the control unit having electronic characteristics and cause malfunction. When a backflow preventer and / or an air filter is present between the T-shaped connecting tube connected to the air discharge part (the third direction), it can be prevented that impurities other than air reach the air discharge pump, and clogging of the air discharge pump can be prevented.
[0040] In addition, an embodiment of the present invention may further include a signal conversion unit. The signal conversion unit may perform a function of converting pressure data, which is an analog signal, into a digital signal and transmitting it to the control unit 14. That is, the signal conversion unit may be an analog-to-digital converter (ADC). The signal conversion unit may perform a function of converting the pressure data acquired as an analog signal into a digital signal so that the control unit 14 can perform information processing.
[0041] In addition, an embodiment of the present invention may further include a memory. The memory may store a program for the operation of the control unit 14, and may also store input / output data (for example, real-time intrathoracic pressure measurement values) or data calculated by the control unit (for example, the maximum value, minimum value, average value, etc. of the intrathoracic pressure within the measurement time). That is, the memory may store measurement data or calculated data and provide it to the control unit 14 to generate result data to be provided to the display unit. Also, the memory may temporarily store measurement data or calculated data, and perform data transfer and data deletion when transfer to a server by wireless communication is possible.
[0042] The memory may include at least one type of storage medium among flash memory type, hard disk type, multimedia card micro type, card type memory (e.g., SD or XD memory, etc.), random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic memory, magnetic disk, and optical disk. The intrathoracic pressure adjustment device 10 can also operate in cooperation with a web storage that executes the storage function of the memory on the internet.
[0043] Further, an embodiment of the present invention may further include a wireless communication unit. The wireless communication unit may execute a function of transferring the measured pressure data or the calculated result data to an external server. The wireless communication unit may be a wireless internet module or a short-range communication module.
[0044] The wireless Internet module is a module for wireless Internet connection and may be built into or externally attached to the intrapleural pressure adjustment device 10. As wireless Internet technologies, Wireless LAN (WLAN), Wireless broadband (Wibro), World Interoperability for Microwave Access (Wimax), High Speed Downlink Packet Access (HSDPA), Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A), etc. can be used.
[0045] The short-range communication module is a module for short-range communication. As short-range communication technologies, Bluetooth (registered trademark), Bluetooth Low Energy (BLE), Beacon, Radio Frequency Identification (RFID), Near Field Communication (NFC), Infrared Data Association (IrDA), ZigBee, etc. can be used.
[0046] In addition, the intrathoracic pressure adjustment device 10 of the present invention may further include an identification information acquisition unit. The identification information acquisition unit may perform a function of acquiring the identification information of the patient. For example, the identification information acquisition unit may be a barcode recognition module, and may read the barcode carried by the patient to recognize the identification information of the patient. The identification information of the patient acquired by the identification information acquisition unit may be matched with the intrathoracic pressure data of the patient to be measured (i.e., the result data), and the wireless communication unit may match the patient identification information and the result data and transfer them to the external server. Thereby, medical staff can distinguish and check the result data stored in the external server for each patient.
[0047] In addition, the intrathoracic pressure adjustment device 10 of the present invention may further include a power supply unit. The power supply unit can be supplied with an external power supply and an internal power supply under the control of the control unit 14 to supply the power required for the operation of each component. In one example, the power supply may be a wired / wireless power supply and / or a portable battery type, but is not limited thereto.
[0048] In addition, the control unit 14 in an embodiment of the present invention may set the current state to zero gauge pressure by operating a zero point adjustment button.
[0049] FIG. 2 is a flowchart of an intrathoracic pressure adjustment method using the intrathoracic pressure adjustment device according to an embodiment of the present invention.
[0050] The intrathoracic pressure measurement method according to an embodiment of the present invention will be described in order.
[0051] The method shown in FIG. 2 is performed by the intrathoracic pressure adjustment device 10 described above with reference to FIG. 1. Therefore, even the content omitted below, the content described with respect to the intrathoracic pressure adjustment device 10 shown in FIG. 1 is also applicable to FIG. 2.
[0052] Referring to FIG. 2, another embodiment of the method for measuring intrathoracic pressure according to the present invention includes a step of inserting the thoracic insertion portion 11 into the thorax (S210), a step of measuring the intrathoracic pressure (S220), a step of determining whether to discharge the air in the thorax to the outside based on the measured numerical data of the intrathoracic pressure (S230), and a step of discharging the air from the thorax to the outside based on the determination of whether to discharge the air in the thorax to the outside (S240).
[0053] Further, when the thoracic insertion portion 11 includes a syringe needle, the step of inserting the thoracic insertion portion 11 into the thorax (S210) may be characterized by inserting the syringe needle into the thorax.
[0054] First, in step S210, the user inserts the thoracic insertion portion 11 of the intrathoracic pressure adjustment device 10 into the thorax. For example, when the thoracic insertion portion 11 includes a syringe needle, the user can insert the syringe needle into the thorax by piercing it.
[0055] In step S220, the intrathoracic pressure is measured. At this time, the control unit 14 of the intrathoracic pressure adjustment device 10 can calculate the pressure data and / or result data (for example, real-time pressure measurement value, maximum value, minimum value, average value, etc. within a specific period) to be provided to the user based on the numerical data of the intrathoracic pressure measured by the pressure measurement unit 12, and generate and transmit the data to the display unit 13 in a form provided to the user. The display unit 13 may display the result data in the form of text or a graph.
[0056] In step S230, it is determined whether to discharge the air in the thorax to the outside based on the measured numerical data of the intrathoracic pressure.
[0057] In step S240, air is discharged from inside the chest cavity to the outside based on a determination of whether to discharge the air inside the chest cavity to the outside. At this time, air is discharged from inside the chest cavity to the outside through the air discharge unit 15 of the device. As an example, through the air discharge unit 15 connected to the control unit 14, the user discharges air from inside the chest cavity to the outside at a constant speed. At this time, the air discharge may be discharged only in one direction from inside the chest cavity to the outside.
[0058] When discharging air from inside the chest cavity to the outside through the air discharge unit 15, the control unit 14 can control the discharge speed of the air discharged from inside the chest cavity to the outside through the air discharge unit 15 within a constant speed range. As an example, it can discharge air from inside the chest cavity at a speed of 50 to 200 cc / min, specifically 85 to 200 cc / min, and more specifically 100 cc / min.
[0059] Further, the air discharge unit 15 may further include a valve for discharging air from inside the chest cavity to the outside in one direction, but is not limited thereto. At this time, the valve is usually closed and may be opened by the user's operation or automatically when discharging air.
[0060] The above description of the present invention is for illustrative purposes. Those with ordinary knowledge in the technical field to which the present invention belongs will be able to easily deform it into other specific forms without changing the technical idea and essential features of the present invention. Therefore, it must be understood that the embodiments described above are exemplary in all respects and not restrictive. For example, each component described as a single type may be implemented dispersedly, and similarly, the components described as dispersed may also be implemented in a combined form.
[0061] The scope of the present invention is shown by the claims described later rather than the above detailed description, and all changes or modified forms derived from the meaning and scope of the claims and their equivalent concepts should be construed as being included in the scope of the present invention.
[0062] The language used in this specification and the claims is not to be construed in a limiting sense according to ordinary or dictionary meanings. Instead, in accordance with the principle that the inventor can appropriately define the concept of terms in order to best explain the invention, it is to be construed in a meaning and concept corresponding to the technical idea of the present invention. Therefore, the configurations such as the embodiments described in this specification are merely one of the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention. Thus, it must be understood that there may be various equivalents and modifications that can replace them at the time of this application.
[0063] The terms used in the present invention are selected as generally used terms that are currently widely used as much as possible while considering the functions in the present invention. However, this may change depending on the intentions of those skilled in the art, precedents, or the emergence of new technologies. Also, in certain cases, there are terms arbitrarily selected by the applicant, and in this case, the meaning thereof is described in detail in the explanatory part of the invention. Therefore, the terms used in the present invention must be defined based not on the simple name of the terms but on the meaning they have and the overall content of the present invention.
[0064] Throughout the specification, when a certain part states that a certain component "includes", this means, unless otherwise specified, that it does not exclude other components and may further include other components. Furthermore, terms such as "... part", "... unit", "... module" described in this specification mean a unit that processes at least one function or operation, and this can be realized by hardware or software, or a combination of hardware and software.
[0065] Hereinafter, with reference to the accompanying drawings, embodiments of the present invention will be described in detail so that those having ordinary knowledge in the technical field to which the present invention pertains can easily implement it. However, the present invention can be realized in various different forms and is not limited to the embodiments described herein. Also, in the drawings, parts not related to the description are omitted in order to clearly explain the present invention, and throughout the specification, similar reference numerals are given to similar components.
[0066] A thoracic cavity pressure adjustment device according to an embodiment of the present invention may include a thoracic cavity insertion part disposed in the thoracic cavity, a pressure measurement part for measuring the thoracic cavity pressure, a control part for generating data numerical values of the measured thoracic cavity pressure, and an air discharge part for discharging air from the thoracic cavity to the outside.
[0067] The thoracic cavity insertion part of the thoracic cavity pressure adjustment device may include a syringe needle and / or a connecting tube. More specifically, the thoracic cavity insertion part is inserted into the thoracic cavity between the visceral pleura and the parietal pleura that wraps the outside of the lung by penetrating the parietal pleura in the body, and may include a detachable syringe needle and connecting tube.
[0068] The air discharge part of the thoracic cavity pressure adjustment device may discharge air from the thoracic cavity to the outside and may include a pump for that purpose. At this time, the discharge direction of the air by the pump is one direction from the thoracic cavity to the outside, and the speed may be characterized by being constant.
[0069] In one embodiment, when air is discharged from the thoracic cavity to the outside through the pump of the air discharge unit, the control unit of the device of the present invention can control the discharge rate of the air discharged from the thoracic cavity to the outside through the air discharge unit within a certain speed range. Specifically, when using the device of the present invention to discharge air from the thoracic cavity to the outside at an appropriate speed, the speed can be controlled within a certain speed range. In one example, the air can be discharged from the thoracic cavity at a discharge rate of 50 to 200 cc / min, specifically 85 to 200 cc / min, and more specifically 100 cc / min. When the discharge rate of the air is less than 50 cc / min, for example, the discharge of air is too slow compared to the inflow of air into the thoracic cavity, and an emergency such as tension pneumothorax may occur. When the discharge rate exceeds 200 cc / min, there is a possibility that lung tissue or cells may be damaged during the process of rapidly discharging the air in the thoracic cavity to the outside.
[0070] The pressure measurement unit of the thoracic cavity pressure adjustment device may be characterized by measuring the thoracic cavity pressure.
[0071] The control unit of the thoracic cavity pressure adjustment device can generate data values of the thoracic cavity pressure. This can calculate the result data based on the thoracic cavity pressure data at the first measurement of the thoracic cavity pressure by the pressure measurement unit, or the thoracic cavity pressure data measured during the discharge of air from the thoracic cavity to the outside through the air discharge unit from the first measurement. Based on the calculated result data, the presence or absence of pneumothorax can be diagnosed, thereby enabling real-time measurement of the thoracic cavity pressure and diagnosis of the presence or absence of pneumothorax.
[0072] Also, in one embodiment, the control unit is characterized in that when discharging air from the thoracic cavity to the outside through the air discharge unit, it can control the discharge rate of the air discharged from the thoracic cavity to the outside through the air discharge unit within a certain speed range.
[0073] Therefore, when discharging air from the thoracic cavity to the outside at an appropriate speed using the device of the present invention, it can be controlled to a constant discharge speed. In one example, the air can be discharged from the thoracic cavity at a discharge speed of 50 to 200 cc / min, specifically 85 to 200 cc / min, and more specifically 100 cc / min. In one example, when the discharge speed of the air is less than 50 cc / min, the discharge of air is too slow compared to the inflow of air into the thoracic cavity, and an emergency such as tension pneumothorax may occur. When the discharge speed exceeds 200 cc / min, lung tissue or cells may be damaged during the process of rapidly discharging the air in the thoracic cavity to the outside.
[0074] The thoracic cavity pressure adjustment device according to another embodiment of the present invention may further include a signal conversion unit that converts pressure data, which is an analog signal, into a digital signal and transmits it to the control unit.
[0075] It may further include a memory for storing the measured pressure data or the result data.
[0076] It may further include a wireless communication unit that transfers the measured pressure data or the calculated result data to an external server.
[0077] It may further include an identification information acquisition unit for acquiring patient identification information, and the wireless communication unit may be characterized by matching the patient identification information and the result data and transferring them to the external server.
[0078] In addition, the thoracic cavity insertion part, pressure measurement part, control part, and air discharge part in the device of the present invention may be connected by a connecting pipe, and a filter for preventing backflow during air discharge and preventing external discharge of impurities other than air may be provided on the connecting pipe.
[0079] According to still another embodiment of the present invention, a method for adjusting intrathoracic pressure includes the steps of inserting a thoracic insertion portion of an intrathoracic pressure adjustment device into the thorax, determining whether to discharge the air in the thorax to the outside based on the measured numerical data of the intrathoracic pressure, and discharging the air from the inside of the thorax to the outside based on the determination of whether to discharge the air in the thorax to the outside.
[0080] Further, when the thoracic insertion portion includes a syringe needle, the step of disposing the thoracic insertion portion in the thorax may be characterized by inserting the syringe needle into the thorax.
[0081] In one embodiment, the method for adjusting intrathoracic pressure may be used for treating, preventing or treating pneumothorax.
