Description

Chest pressure detecting device

The invention relates to a detecting device, in particular to a chest pressure detecting device.

The lung is one of the important organs in the body to perform respiratory function. In general, the lungs are covered by visceral rib membranes and wall rib membranes. The cavity formed by the visceral rib membrane and the wall rib membrane is referred to as a rib membrane cavity. The normal pleural pressure of a typical person is approximately between 10 and 0 cm H ₂ O. When more than a normal amount of pleural fluid or air that should not accumulate in the pleural cavity, the pressure in the pleural cavity will increase, and the lung tissue will be compressed and affect the respiratory function, which will result in so-called pleural cavity disease, which is generally more common. The pleural cavity disease is pneumothorax, empyema, hemothorax or pleural effusion.

Among the methods for treating pleural cavity disease, therapeutic thoracentesis is a frequently used and simple treatment method. Its purpose is mainly to place the chest tube into the pleural cavity and drain excess pleural effusion or gas to improve the inclusion. Symptoms of chest pain, chest tightness, shortness of breath, or difficulty breathing. Thoracentesis can also be used to diagnose the disease by extracting and examining the effusion of the pleural effusion to find the cause of the effusion. In addition to thoracic puncture, chest X-rays and ultrasound examinations can also be used to help physicians understand the severity of the patient.

In the early monitoring method of pleural pressure, the U-shaped water pipe was used as the manometer. The U-tube hydrometer was less expensive and easy to operate, but if the patient coughed or breathed, it would easily cause water surface turbulence. Even the inhalation of water into the pleural cavity creates difficulties in accurately recording values. Moreover, this method cannot automatically store data and analyze data, and it is quite inconvenient to manually calculate the approximate value and store the data. In addition, after further research and development by the researchers, a vascular pressure transducer was used to obtain the signal. However, vascular pressure transducers are medical grade items. In the process of detecting the blood vessel pressure transducer, it is necessary to directly contact the human body, so it is a consumable item that cannot be reused, resulting in a relatively high cost. In addition, additional time is required during reoperation to measure pleural pressure.

In the prior art, in the process of monitoring the physiological state of a patient, the pressure measuring device needs to be in direct contact with the patient's body, which is a consumable medical product, and the cost is high. Therefore, the inventors hope to develop a new pressure measuring device that can be reused without being directly in contact with the patient, thereby reducing cost. Moreover, before the operation, the severity of the disease can be known through the measurement of the pleural pressure. During the operation, the change in pleural pressure can also be displayed immediately, allowing the physician to respond in time when excessive negative pressure is generated. After the operation, the patient is taken with him to record the pleural pressure data at any time to provide a more complete information of the physician to assess the degree of recovery of the patient.

It is an object of the present invention to provide a chest pressure detecting device that measures chest pressure during thoracentesis drainage.

In order to provide a better understanding and understanding of the features and the efficacies of the present invention, the preferred embodiment and the detailed description are as follows:

Please refer to the first figure, which is a schematic diagram of a first embodiment of a chest pressure detecting device of the present invention. As shown, the present embodiment is a chest pressure detecting device 1 which can be used during chest surgery (thoracic puncture) to detect the pressure inside the chest cavity. The chest pressure detecting device 1 includes a chest drainage module 10 and a pressure detecting module 20. The chest drainage module 10 further includes a chest drainage tube 11, a water seal bottle 13 and a vent tube 15. The chest drainage tube 11 is used to guide the excess fluid and air discharged from the chest cavity. The pressure detecting module 20 is disposed on one side of the chest drainage tube 11 and communicates with the chest drainage tube 11 . The pressure detecting module 20 can be used to detect the pressure inside the chest cavity while performing thoracic puncture and draining the liquid and air in the chest cavity. This allows for immediate monitoring of changes in the pressure in the thoracic cavity, which helps to determine the clinical status, which is conducive to the diagnosis and subsequent treatment.

In the embodiment, the chest pressure detecting device 1 is a combination of the chest drainage module 10 and the pressure detecting module 20. The chest drainage module 10 includes a water-sealed bottle 13 having a closed accommodating space 130 for accommodating a liquid 100 (eg, water). One end of the chest drainage tube 11 communicates with the accommodating space 130. The liquid 100 is under the other end, and the other end of the chest drainage tube 11 has a thoracic puncture structure 111 which is located outside the water seal bottle 13. One end of the vent pipe 15 communicates with the accommodating space 130 and is located above the liquid 100. The other end of the vent pipe 15 is located outside the water seal bottle 13 and is externally connected to the general atmosphere. The pressure detecting module 20 is disposed on one side of the chest drainage tube 11 and communicates with the chest drainage tube 11.

Please refer to the second figure, which is a schematic diagram of electrical connection of an embodiment of the pressure detecting device of the present invention. As shown in the figure, this embodiment is for explaining the pressure detecting module 20. The pressure detecting module 20 further includes a pressure sensing unit 21, a signal processing unit 23 and a display unit 25. The pressure sensing unit 21 detects at least one pressure signal 210. The signal processing unit 23 receives the pressure signal 210 and sends a display signal 230. The display unit 25 receives and displays the display signal 230. The pressure detection module 20 further includes a power supply unit 27. The power supply unit 27 supplies power to the pressure sensing unit 21, a signal processing unit 23, and a display unit 25. In addition, the pressure detecting module 20 further includes a storage unit 29 that receives and stores the display signal 230. The storage unit 29 is a general memory card (such as SD or microSD, etc.) or a flash drive, etc., so that the replacement or access of the storage unit of the pressure detecting module 20 is more convenient.

Please refer to FIG. 3A and FIG. 3B together, which are schematic diagrams showing the state of use and connection relationship of the first embodiment of the chest pressure detecting device of the present invention. As shown in the figure, the chest pressure detecting device 1 of the present embodiment is used for the process of performing thoracic puncture. In the chest of the human body, there is a space between the lung 31 and the chest wall 33, which is called the pleural cavity 30. This space (i.e., the pleural cavity 30) is covered by the visceral rib membrane 310 of the lung 31 and the wall rib membrane 330 of the chest wall 33. Under normal circumstances, the visceral pleura 310 and the parietal pleura 330 are close together, and there is only a small amount of liquid (about 5-15 cc) in the pleural cavity 30 as a lubricant for expansion and contraction of the lungs 31. The pleural cavity 30 is normally maintained in a negative pressure state under normal conditions. If the lungs 31 leak, the air flows into the pleural cavity 30, so that the negative pressure disappears, and the lungs that maintain the normal lung respiratory function collapse, that is, the pneumothorax. The pneumothorax causes the pressure in the pleural cavity 30 to become a reference value of zero, so that the pressure of the alveoli also becomes zero, and the lungs are inflated and unable to inhale. In addition, when a pleural fluid exceeding a normal amount or air which is not present accumulates in the pleural cavity 30, the pressure of the pleural cavity 30 is increased, causing compression of the lung tissue and affecting the respiratory function, that is, a so-called pleural cavity disease occurs. Therefore, chest drainage is required to restore the negative pressure in the pleural cavity 30, so that the lungs re-expand.

In the above case, the chest pressure detecting device 1 is used to perform a therapeutic thoracentesis on the patient, and the thoracic puncture structure 111 at the other end of the thoracic drainage tube 11 of the chest drainage module 10 performs thoracic puncture to make the chest cavity. The puncture structure 111 communicates with the pleural cavity 30 to communicate the thoracic drainage tube 11 to the pleural cavity 30. One end of the chest drainage tube 11 is located in the liquid 100 of the water seal bottle 13, and its nozzle is about immersed 3 cm below the surface of the liquid 100, and the liquid 100 is water. One end of the vent pipe 15 communicates with the air in the water seal bottle 13, and the other end thereof communicates with the atmosphere outside the water seal bottle 13.

When the pressure in the pleural cavity 30 exceeds 3 cm of water, which indicates that the pleural cavity is positive pressure (ie, the pressure in the pleural cavity 30 is greater than the general atmospheric pressure), the pressure of the pleural cavity is balanced with the general atmospheric pressure to promote the pleural cavity. The air or liquid within 30 is discharged and guided along the chest drainage tube 11 to be discharged into the water seal bottle 13. In the above process, the pressure detecting module 20 is connected to the chest drainage tube 11, and the pressure sensing unit 21 of the pressure detecting module 20 is a gas sensor, which is for the chest drainage tube 11 Air pressure is detected. After the pressure sensing unit 21 senses the change of the gas pressure, it sends the pressure signal 210 to the signal processing unit 23. After the signal processing unit 23 performs signal amplification and analog signal conversion into a digital signal, the pressure signal 210 is converted into the display signal 230. The display unit 25 receives and displays the display signal 230. The display signal 230 can be a waveform diagram or a data display to provide a doctor or user to monitor the pressure change in the pleural cavity 30 in real time.

When the pressure in the pleural cavity 30 is a negative pressure (ie, the pressure in the pleural cavity 30 is less than the normal atmospheric pressure), the liquid in the water seal bottle 13 is attracted into the chest drainage tube 11 and into the pleural cavity. Guided by 30 directions. Therefore, the horizontal height of the water seal bottle 13 needs to be lower than the level of the pleural cavity 30. At this time, the liquid column of the chest drainage tube 11 has a hydrostatic pressure against the negative pressure in the pleural cavity 30 to prevent the water seal bottle. The liquid 30 within 13 is returned to the pleural cavity 30. Therefore, when the hydrostatic pressure balance is reached, the liquid column in the chest drainage tube 11 is maintained at a certain height. At this time, changing the relative height between the water seal bottle 13 and the pleural cavity 30 affects the chest drainage tube 11 The change in the liquid column inside. The pressure of the gas detected by the pressure sensing unit 21 of the pressure detecting module 20 is also stabilized by a pressure within a certain range.

The chest pressure detecting device 1 of the present embodiment can detect the above situation, and when the chest drainage tube 11 of the chest drainage module 10 communicates with the pleural cavity 30, the pressure detecting module 20 can be used for the pleural membrane. Detection of chamber 30 pressure. Furthermore, the pressure detecting module 20 of the embodiment has the power supply unit 27, which is more convenient to carry around, and is convenient for monitoring the pressure change in the pleural cavity 30 in real time. In addition, the pressure detecting module 20 has the storage unit 29, which can store the pressure data of the detected pleural cavity 30 to facilitate the doctor or the user to track and understand the recovery condition of the patient.

This embodiment improves the disadvantages of the prior art. In the process of monitoring the physiological state of a patient, the pressure measuring device needs to directly contact the patient's body, which is a consumable medical product, and costs cost. high. Moreover, it is necessary to perform measurement operations other than surgery, so it takes extra time to measure the patient using the pressure measuring device. The present embodiment provides a pressure detecting device, which is advantageous in that the pressure in the pleural cavity 30 of the patient is measured during the operation of the thoracic puncture of the patient, so that it is not necessary to perform surgery. Measuring the action will not take extra time. And the pressure measurement method of the pleural cavity is simple, and it is not necessary to perform complicated pre-use training and complicated operation. The pressure detecting device 20 is disposed on one side of the chest drainage tube 11 and communicates with the chest drainage tube 11, which is not in direct contact with the patient. When the chest pressure detecting module 20 needs to be repeatedly used, only the chest drainage tube 11 needs to be replaced. This method can save more cost than the conventional detection device needs to be completely discarded. Furthermore, in the process of thoracic puncture, simultaneous chest pressure detection, the additional benefit is that the internal pressure value of the patient's pleural cavity can be instantly known, and the pleural cavity will be under different internal pressure values. Different symptoms and related conditions are issued, and the physician can assist in judging the physical condition of the patient by objectively relevant pressure data. Furthermore, it is possible to prevent excessive negative pressure from being formed in the chest cavity due to excessive liquid introduction, and excessive negative pressure in the pleural cavity may cause pulmonary edema and related complications again. In addition, during the chest drainage process, the pressure change of the pleural membrane is monitored. This method can be used to determine whether the patient's pleural cavity has been fully expanded or is still dilated, and it is more effective to judge the patient's lung recovery from an objective angle. Quickly and effectively assist the physician in determining the clinical status as a basis for diagnosis or subsequent treatment.

Please refer to the fourth figure, which is a schematic diagram of a second embodiment of the chest pressure detecting device of the present invention. As shown in the figure, the chest drainage module 10 of the first embodiment further includes a collection bottle 17 and a communication tube 19. The collection bottle 17 of the present embodiment has a closed chest cavity liquid accommodating space 170 for accommodating a chest fluid 200, and one end of the chest drainage tube 11 communicates with the chest cavity liquid accommodating space 170. One end of the communication tube 19 is in communication with the chest liquid accommodation space 170. The water-sealed bottle 13 has a accommodating space 130 for accommodating the liquid 100. The other end of the communicating tube 19 communicates with the accommodating space 130 and is not below the liquid 100. One end of the vent pipe 15 communicates with the accommodating space 130 and is located above the liquid 100. The pressure detecting module 20 is disposed on one side of the chest drainage tube 11 and communicates with the chest drainage tube 11.

As described above, the collection bottle 17 of the present embodiment is for increasing the space for collecting the liquid or gas guided by the chest drainage tube 11. Since the liquid or the liquid discharged from the pleural cavity 30 is accumulated in the water seal bottle 13 by the manner of the first embodiment, the liquid 100 in the water seal bottle 13 is caused to be formed. Ascending, thereby changing the pressure of the hydrostatic pressure within the chest drainage module 10, approaches equilibrium, and the pressure required to direct the pleural chamber 30 to discharge liquid or air also increases. Moreover, the accommodating space 130 of the water seal bottle 13 is also reduced, and even because the space of the accommodating space 130 is insufficient, the liquid guided by the pleural cavity 30 is excessive, and the water seal bottle 13 needs to be replaced. Therefore, in this embodiment, the collecting bottle 17 is further provided for collecting the liquid and the gas in the chest cavity, so that the liquid 100 surface height of the water sealing bottle 13 and the liquid 100 immersed in the water sealing bottle 13 The effect of the liquid height inside the tube (ie, the liquid column height) is small. Thus, the hydrostatic pressure of the chest drainage module 10 is prevented from being affected, and the chest drainage module 10 can perform chest drainage normally.

Please refer to FIG. 5A, which is a schematic diagram of a third embodiment of the chest pressure detecting device of the present invention. As shown in the figure, the chest drainage module 10 of the first embodiment further includes a suction unit 40. The suction unit 40 is connected to the other end of the vent pipe 15. In the present embodiment, the suction unit 40 attracts the air in the accommodating space 130 of the water seal bottle 13. When the air in the water seal bottle 13 is taken away, the accommodating space 130 inside the water seal bottle 13 In a negative pressure state, the positive pressure state in the upper pleural cavity 30 (please refer to the third B diagram) is used to increase the drainage speed of the chest drainage module 1. Furthermore, the way of chest drainage is that the pleural cavity 30 is in a positive pressure state, and the liquid or air in the pleural cavity 30 is actively discharged into the water seal bottle 13 of the chest drainage module 10. However, when the liquid or air in the pleural cavity 30 is discharged, the positive pressure in the pleural cavity 30 becomes small, and the negative pressure of the water-sealed bottle 13 becomes small, and the pressure between the two approaches the balance, the chest drainage The speed is relatively slower. Therefore, the suction unit 40 continuously maintains the negative pressure in the water seal bottle 13 to maintain the speed of the chest drainage of the chest drainage module 10.

Please refer to FIG. 5B, which is a schematic view of a fourth embodiment of the chest pressure detecting device of the present invention. As shown in the figure, the chest drainage module 10 of the second embodiment further includes a suction unit 40. The suction unit 40 is also connected to the other end of the vent pipe 15. In this embodiment, the structure, the manner of use, and the effect of the attraction unit 40 are the same as those of the third embodiment, and thus are not described herein.

Please refer to FIG. 6A, which is a schematic diagram of a fifth embodiment of the chest pressure detecting device of the present invention. As shown in the figure, the present embodiment further includes a pressure regulating tube 41, a pressure measuring bottle 42, an auxiliary venting tube 43, and a suction unit 40, as compared with the first embodiment. The pressure measuring bottle 42 has a closed liquid accommodating space 420 for accommodating a liquid 100. One end of the pressure regulating tube 41 communicates with the liquid accommodating space 420 and is immersed under the liquid 100. The snorkel The other end of the auxiliary venting pipe 43 communicates with the liquid accommodating space 420 and is located above the liquid 100. The suction unit 40 is in communication with the other end of the auxiliary vent pipe 43.

As described above, the air in the accommodating space 130 of the water seal bottle 13 communicates with the air in the liquid accommodating space 420 of the pressure measuring bottle 42. The air in the liquid accommodating space 420 of the pressure measuring bottle 42 is further communicated with the suction unit 40 of the pressure measuring bottle 42. In the present embodiment, the suction unit 40 attracts the air in the accommodating space 130 of the water seal bottle 13 and the air in the liquid accommodating space 420 of the pressure measuring bottle 42, so that the internal space is maintained at a negative pressure. status. Further, since one end of the pressure regulating tube 41 of the pressure measuring bottle 42 is not under the liquid 100, the other end thereof is located outside the pressure measuring bottle 42, and is connected to the general atmosphere. At this time, the negative pressure state of the internal space affects both the air in the pressure regulating tube 41 (the general atmosphere that is externally connected) and the air in the chest drainage tube 11 (the air in the pleural cavity), that is, the pressure is affected. The height of the liquid column in the adjustment tube 41 and the height of the liquid column in the chest drainage tube 11 are adjusted. By the pressure regulating tube 41, the direct influence of the internal space negative pressure state on the chest drainage tube 11 can be shared and adjusted, and the drainage pressure of the chest drainage tube 11 can be adjusted in a gentle manner. In this way, it is possible to avoid an excessive attraction force in the pleural cavity 30 due to the excessive attraction of the attraction unit 40, and indirectly damage the lungs.

Please refer to FIG. 6B, which is a schematic diagram of a sixth embodiment of the chest pressure detecting device of the present invention. As shown in the figure, the present embodiment further includes a pressure regulating tube 41, a pressure measuring bottle 42, an auxiliary venting tube 43, and a suction unit 40, as compared with the second embodiment. The embodiment is the same as that described in the fifth embodiment, and the structure, the manner of use and the effect of the above-mentioned components are the same as those of the fifth embodiment, and therefore, the details are not described herein.

Further, in the configurations of the fifth embodiment and the sixth embodiment, an auxiliary suction unit (not shown) which is connected to the other end of the pressure regulating tube 41 can be further provided. The auxiliary suction unit can attract the air in the pressure regulating tube 41, that is, the height of the liquid column in the pressure regulating tube 41 can be increased. Thus, the auxiliary suction unit can resist the negative pressure generated in the accommodating space 130 of the water seal bottle 13 and the liquid accommodating space 420 of the pressure measuring bottle 42 by the attraction of the suction unit 40. The auxiliary suction unit can be identical to the suction unit 40. The drainage pressure of the chest drainage module 11 for the pleural cavity 30 is adjusted in the above manner.
