Description

TECHNICAL FIELD

[0001] The utility model relates to additive manufacturing technology field, concretely relates to a multi -mode dynamic accurate flow regulation and emergency quick response chest cavity drainage bottle. BACKGROUND

[0002] Traditional chest cavity drainage bottles are mainly used for the treatment of pleural effusion and pneumothorax caused by postoperative or disease. The existing chest cavity drainage bottles usually only provide a single flow control mode, i.e. fixed water column height, which cannot adapt to the rapid changes of patient conditions, especially in emergency situations. In addition, the existing technology has limitations in accurately controlling the flow, which cannot achieve rapid response and accurate adjustment, thereby affecting the treatment effect and patient safety.

[0003] According to the statistics of literature, the complication rate of chest drainage is as high as 10%~30%, among which the most common ones are poor drainage, infection, bleeding, etc. These complications are often related to the flow control of chest drainage, for example, excessive flow may cause lung collapse or pneumothorax, insufficient flow may cause effusion or infection, unstable flow may cause chest pressure fluctuation or water seal rupture, etc. Therefore, the flow control of chest drainage is a key factor affecting patient treatment and safety.

[0004] The reaction speed of the flow control of the existing technology is 5 minutes on average, the adjustment accuracy is 10 ml / min on average, and the stability is 15% on average. These data show that the performance of the flow control of the existing technology is not good, which cannot meet the needs of patients, especially in emergency situations, which may lead to the deterioration of patients' condition or the occurrence of complications.

[0005] The existing chest drainage bottles have deficiencies in dealing with emergency situations and providing accurate flow control, which cannot meet the complex clinical needs. Especially in the case of acute pleural effusion or other situations that require rapid medical intervention, the reaction speed and adjustment accuracy of the existing technology are insufficient, which may increase the risk of patients.

[0006] For example, when a patient has acute pleural effusion, it is necessary to quickly drain the fluid in the chest cavity to reduce the pressure in the chest cavity, prevent the heart or lungs from being pressed, and cause dangerous situations such as difficulty breathing or heart stop. However, the existing technology cannot achieve the function of rapidly increasing the flow, and can only be realized by manually adjusting the water column height or replacing the drainage bottle of different specifications, which not only consumes time and effort, but also is prone to errors or contamination, affecting the safety and comfort of patients.

[0007] On the other hand, when the patient's pleural effusion or pneumothorax gradually decreases, the flow rate needs to be reduced to maintain the balance of the chest pressure, promote the recruitment and recovery of the lung, and prevent the recurrence of lung collapse or pneumothorax. However, the prior art cannot achieve the function of precisely adjusting the flow rate, and can only be judged by manually observing the fluctuation of the water seal or listening to the sound of the chest, which is not only inaccurate but also easy to miss or delay, affecting the treatment and recovery of the patient.

[0008] Therefore, the existing chest drainage bottle has technical problems in dealing with emergency situations and providing precise flow control, and needs to be improved and innovated. SUMMARY

[0009] In order to overcome the problems in the prior art, the purpose of the present application is to provide a multi-mode precise adjustment and emergency quick response chest drainage bottle for treating patients with pleural effusion or pneumothorax, especially in the case of requiring rapid or precise flow control, to provide more effective and safe chest drainage.

DETAILED DESCRIPTION

[0025] Example 1

[0026] The present embodiment is to provide a multi-mode precise adjustment and emergency rapid response chest drainage bottle, as shown in the figure, which comprises a drainage bottle and a drainage tube 2, the drainage bottle comprises an effusion bottle 9 and a water seal bottle 11, the effusion bottle 9 is provided with a drainage tube interface 8, one end of the drainage tube 2 is connected to the effusion bottle 9 through the drainage tube interface 8, and the other end is connected to a chest retention tube interface. When the patient's chest cavity forms high pressure due to gas and liquid accumulation, the gas and liquid in the chest cavity can be discharged into the effusion bottle 9 through the drainage tube 2, and the effusion bottle 9 is used to collect and store the drainage liquid drained from the patient's body, which is convenient for medical staff to observe the amount, color and properties of the drainage liquid in the effusion bottle to preliminarily judge the patient's condition. Figure 1 The water seal bottle 11 is provided with an air inlet tube 10, the effusion bottle 9 is provided with an air inlet tube interface 18, one end of the air inlet tube 10 is connected to the air inlet tube interface 18, and the other end extends to the bottom of the water seal bottle 11, the water seal bottle 11 is also provided with an air outlet tube interface 16, the air outlet tube interface 16 is sleeved with an air outlet tube interface cover 17, and the interface cover 17 is used to prevent foreign matter from entering the water seal bottle 11. In the working process, the water seal bottle 11 contains liquid, and the liquid in the water seal bottle 11 plays a role of isolating the chest cavity from the outside world, when the negative pressure in the chest cavity is restored, the liquid in the water seal bottle 11 will be attracted upward, thereby forming a negative pressure water column in the air inlet tube 10, preventing air from entering the chest cavity. At the same time, medical staff can observe the fluctuation of the water column in the water seal bottle to judge the patency of drainage and the change of pressure in the chest cavity.

[0027] The drainage bottle further comprises a liquid injection device 13, the liquid injection device 13 is provided with a connecting tube 14, the water seal bottle 11 is provided with a liquid injection interface 12, and the liquid injection device 13 is connected to the liquid injection interface 12 through the connecting tube 14 to communicate with the water seal bottle.

[0028] In the present embodiment, the drainage tube 2 adopts a heat preservation material, and the temperature of the drainage liquid is suitable, so that the drainage liquid is not easy to form precipitates or crystals in the drainage tube, which can effectively reduce the risk of blockage of the drainage tube. If the drainage tube is blocked, not only the drainage effect will be affected, but also the drainage tube may need to be replaced, increasing the pain and medical cost of the patient.

[0029]

[0030] ​The drainage tube 2 is provided with a color recognition device 3 and an electromagnetic valve 6, the color recognition device 2 and the electromagnetic valve 6 are electrically connected with a controller, and the controller is used for analyzing the color of the liquid in the drainage tube 2 and controlling the opening and closing of the electromagnetic valve 6. Normal pleural effusion is usually clear or light yellow, if the color recognition device 6 recognizes that the drainage liquid in the drainage tube 2 is continuously milky white, red, pus-like yellowish white, grass green and the like, it is considered to be an abnormal color, and the controller timely closes the electromagnetic valve 6 to stop the pleural drainage.

[0031] The drainage tube 2 is further provided with a pressure sensor 4 and a flow sensor 5 away from the drainage tube interface 8, and the pressure sensor 4 and the flow sensor 3 are electrically connected with the controller. In this embodiment, a controller with high frequency is used to receive and process the signals collected by the pressure sensor 4 and the flow sensor 3. A maximum pressure threshold is set for the pressure sensor 4, in an emergency such as acute pleural effusion, when the pressure sensor 4 monitors that the pleural pressure reaches the maximum pressure threshold, the controller quickly responds to open the electromagnetic valve 6, timely reduces the pleural pressure, and prevents the occurrence of dangerous conditions such as respiratory difficulty or heart compression caused by high pleural pressure. Moreover, the pressure sensor 6 can monitor the pressure change in the pleural cavity in real time and accurately, if the pressure in the pleural cavity abnormally rises or falls, the medical staff can be timely reminded to take corresponding measures, so as to ensure the safety of the patient.

[0032] The flow sensor 5 can monitor the flow of the pleural drainage liquid in real time during the pleural drainage, and provide instant data feedback for the medical staff. The medical staff can set a maximum flow threshold in advance, when the flow sensor 5 monitors that the flow of the drainage liquid reaches the maximum flow threshold, the controller timely closes the electromagnetic valve 6 to stop the pleural drainage, so as to avoid too much drainage at one time. Moreover, through the real-time feedback of the amount and change trend of the drainage volume, the medical staff can judge whether the patient's condition is stable or improved.

[0033] The drainage tube 8 is further provided with a control valve 7, the control valve 7 can adjust the flow size according to the signal sent by the controller, the controller receives the real-time pressure value from the pressure sensor 4, when the pressure value received by the controller is larger, the controller will send a signal to the control valve 7 to adjust to a larger opening to increase the flow in the drainage tube; on the contrary, when the pressure value received by the controller is smaller, the controller will send a signal to the control valve 7 to adjust to a smaller opening to reduce the flow in the drainage tube. At the same time, the control valve 7 also supports manual control of the flow size, which is convenient for doctors to freely and flexibly adjust, for example, for some patients with relatively stable conditions, the drainage speed can be appropriately slowed down; and for patients with severe conditions, who need to quickly drain the effusion or gas, the drainage speed can be accelerated.

[0034] A liquid level sensor 19 is arranged on the inner wall of the effusion bottle 9 below the drainage tube interface 8, for monitoring the amount of liquid in the effusion bottle 9. The liquid level sensor 19 is electrically connected to the controller. When the liquid in the effusion bottle 9 is close to overflowing, the medical staff is reminded to replace the drainage bottle in time to prevent poor drainage caused by the effusion bottle 9 overflowing.

[0035] A buzzer alarm device is also included, which is electrically connected to the controller. When the color recognition device 3 identifies an abnormal color of the drainage fluid, when the pressure sensor 4 monitors that the pressure in the drainage tube 2 is too high or too low, when the flow sensor 5 monitors that the flow of the drainage fluid is abnormal, or when the liquid level sensor 16 monitors that the liquid in the effusion bottle 9 is close to overflowing, the buzzer alarm device will promptly issue an alarm prompt to call the doctor for clinical evaluation and treatment.

[0036] A display 15 is also included, which is electrically connected to the controller through the connection line 1, for providing a visual interface to display the drainage condition and adjust the flow setting. The display 1 is provided with an intuitive user interface for the medical staff to monitor the drainage condition and adjust the flow setting. The user interface displays real-time flow, chest pressure, and other important parameters, while providing manual adjustment options for adjustment in special cases, such as opening and closing the electromagnetic valve 6 by the controller, switching the control valve between automatic and manual control modes, etc. The user-friendly interface design simplifies the operation process and reduces the risk of operation errors.

[0037] Embodiment 2

[0038] The difference between this embodiment and embodiment 1 is that, as shown in Figure 1 , the liquid injector, water seal bottle, and effusion bottle of embodiment 1 can be designed separately. The liquid injector, water seal bottle, and effusion bottle can also be designed as a whole, as shown in Figure 2 , Figure 3 . Specifically, the liquid injector 13 is arranged between the effusion bottle 9 and the water seal bottle 11, and the horizontal center line of the liquid injector 13 is higher than the height of the center line of the water seal bottle 11, which facilitates the injection of liquid into the water seal bottle 11.
