Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a disposable visualized thoracentesis and drainage device. Background Art

[0002] Pleural effusion is a common clinical symptom characterized by pathological fluid accumulation in the pleural cavity. The pleural cavity is a potential gap between the visceral and parietal pleura. In normal people, there is 5-15 ml of fluid in the pleural cavity, which acts as a lubricant during breathing movements. 500-1000 ml of fluid is formed and absorbed in the pleural cavity every day. Pleural effusion can occur if any reason causes increased production or decreased absorption of fluid in the pleural cavity. According to its occurrence mechanism, it can be divided into two types: transudative pleural effusion and exudative pleural effusion. If there is too much fluid in the cavity, compressing the lungs or the effusion time is too long, the fibrin in it is easy to organize and cause adhesion of the two layers of pleura, thereby affecting the respiratory function of the lungs.

[0003] Thoracentesis is a common procedure used clinically to treat pleural effusion or gas. Thoracentesis refers to the operation of using a sterilized needle to puncture the skin, intercostal tissue, or parietal pleura into the pleural cavity. If fluid is found in the patient's pleural cavity through examination, the fluid can be extracted through thoracentesis, and various examinations can be performed to find the cause of the disease. However, traditional puncture methods have certain operational blind spots, which increase the risk of accidentally puncturing structures such as lung tissue and blood vessels, leading to complications such as pneumothorax and bleeding. In order to improve the safety of puncture, there is an urgent need for a thoracentesis and drainage device with visual guidance and precise positioning to help doctors avoid damage to important tissues during the puncture process. Summary of the invention

[0004] The purpose of the present invention is to provide a disposable visualized thoracocentesis and drainage device, comprising: a drainage component, a puncture needle, a miniature camera, an LED light source, and a display device.

[0005] The drainage component is designed as a one-way valve, and one end is connected to the puncture needle.

[0006] The end of the drainage component away from the puncture needle is provided with a drainage tube interface for connecting with the drainage tube.

[0007] A miniature camera is arranged at one end of the puncture needle away from the drainage component, and the miniature camera is surrounded by an LED light source.

[0008] The puncture needle punctures the chest cavity of the user, so that the drainage component, the puncture needle, the micro camera, and the LED light source enter the chest cavity of the user.

[0009] The micro camera is used to capture the internal image data of the user's chest cavity.

[0010] The LED light source provides lighting for the micro camera.

[0011] The display device is used to display the image data acquired by the micro camera during the puncture and drainage process.

[0012] Furthermore, the LED light source provides 300 lumens to 500 lumens of light.

[0013] Furthermore, the needle tip of the puncture needle is a conical structure with a side hole.

[0014] The side hole is used for draining pleural effusion or air.

[0015] Furthermore, the resolution of the micro camera is not less than 5 million pixels.

[0016] Furthermore, the puncture needle has a built-in battery and a control circuit.

[0017] The battery is used to power the micro camera and the LED light source.

[0018] The battery shell is made of degradable material.

[0019] The control circuit is used to control the opening and closing of the micro camera and the LED light source, and transmit the image data acquired by the micro camera during the puncture and drainage process to the display device.

[0020] Furthermore, an automatic avoidance module is integrated in the display device.

[0021] The automatic avoidance module performs real-time recognition of the image data captured by the micro camera, and if lung tissue and blood vessels are present in the image data, a warning signal is issued to avoid damage to the lung tissue and blood vessels.

[0022] Furthermore, the signal transmission mode between the display device and the micro camera includes a wired mode and a wireless mode.

[0023] The wireless method includes Wi-Fi connection and Bluetooth connection.

[0024] Furthermore, the puncture needle has a distance measuring function for locating the area to be drained.

[0025] Furthermore, the micro camera is provided with an anti-fog coating.

[0026] Furthermore, the drainage component and the shell of the display device are made of degradable materials.

[0027] The technical effect of the present invention is unquestionable. The present invention provides a disposable visual thoracic puncture and drainage device, which integrates a micro camera, a light source and a puncture needle, and can monitor the puncture process in real time to avoid damage to important structures such as lung tissue and blood vessels. The device is designed for single use to ensure aseptic operation and avoid cross infection. The device is especially designed for the complex environment in the chest cavity, and improves the accuracy of puncture positioning through visual guidance to ensure the safety of the operation.

[0028] The present invention uses modern microelectronics technology to achieve the integration of a micro high-definition camera and a flexible drainage tube. The puncture needle is specially designed and combined with a visualization system to reduce the risk of tissue damage during surgery. The device has been clinically verified to significantly improve the safety and success rate of thoracentesis surgery, and is particularly suitable for complex thoracentesis operations.

[0029] The present invention proposes an innovative disposable visualized thoracentesis and drainage device with real-time visualization and automatic avoidance functions, which greatly improves the safety of puncture operations, reduces the occurrence of complications, and has significant clinical application value and market potential.
