TECHNICAL FIELD

[0001] The utility model relates to a thoracic drainage tube and belongs to the technical field of medical instruments. BACKGROUND

[0002] Thoracic closed drainage is an important means for treating pleural effusion, pneumothorax and other thoracic diseases. However, the traditional thoracic drainage tube lacks visual support and guidance, so doctors cannot observe the state of the surrounding tissue in real time and control the position of the drainage tube during the operation process, which may lead to operation errors or poor drainage.

[0003] The existing thoracic drainage technology mainly relies on the experience of doctors and the assistance of imaging equipment, and has problems such as inaccurate positioning, complex operation and patient discomfort. Especially during the catheterization and extubation process, the lack of real-time monitoring and accurate positioning may lead to complications. SUMMARY

[0004] The utility model aims at the above technical problems, and provides a thoracic drainage tube which can provide real-time video images and is compact in structure and convenient to use.

[0005] In order to achieve the above purpose, the utility model adopts the technical scheme of:

[0006] A thoracic drainage tube, comprising a tube body, an installation hole extending along the length direction of the tube wall is opened in the tube wall of the tube body, the opening of one end of the installation hole is arranged on the end face of the front end of the tube body, and the opening of the other end of the installation hole is close to the rear end of the tube body and arranged on the side wall of the tube body; a camera is arranged in the installation hole at the front end of the tube body, and the camera is arranged towards the front end port of the tube body; an adapter is arranged outside the tube body at the opening of the installation hole close to the rear end of the tube body, the signal output end of the camera is electrically connected with the signal input end of the adapter; light sources are arranged on both sides of the camera and embedded in the tube wall of the tube body, and the light sources are electrically connected with the signal input end of the adapter.

[0007] In this scheme, one end of the drainage tube needs to be inserted into the patient's body, and the other end can be connected with a drainage bottle, so that the end of the drainage tube inserted into the patient's body is defined as the front end of the drainage tube, and the end connected with the drainage bottle is defined as the rear end of the drainage tube.

[0008] Thus, the camera is embedded in the pipe wall of the pipe body, increasing the integrity of the drainage pipe body; the signal output end of the camera is electrically connected with the adapter at the rear end of the pipe body, and after the adapter is connected with the external display device, the condition in the patient's body can be displayed on the external display device through the camera, and the camera can more clearly reflect the condition in the patient's body under the illumination of the light source; the catheterization process of the drainage tube can be performed under the guidance of real-time images, and the real-time video image provided by the camera helps the doctor to more clearly observe the internal structure of the chest cavity and accurately position the position of the drainage tube, reducing the risk of misoperation.

[0009] According to the embodiments of the present application, the present application can be further optimized, and the following is the technical scheme formed after optimization:

[0010] In order to facilitate the adjustment of the position of the drainage tube outside the body, specifically, the front end of the pipe body is provided with a magnetic member embedded in the pipe wall of the pipe body, and the magnetic member extends along the length direction of the pipe body from the front end of the pipe body to the rear end of the pipe body.

[0011] Specifically, the setting length of the magnetic member is not less than 5cm.

[0012] Specifically, the magnetic member is a nano magnetic particle, and the magnetic member is uniformly arranged along the circumferential direction of the pipe body.

[0013] Thus, the magnetic nano-particle embedded in the front end of the drainage tube can respond to the change of the external magnetic field, so as to realize the adjustment of the position of the drainage tube outside the body. Through the external magnetic field, the doctor can adjust the orientation of the front end of the drainage tube at any time during the operation, so as to adjust the position of the drainage tube and ensure that the best drainage effect is achieved.

[0014] In order to increase the drainage effect, specifically, a plurality of through holes arranged along the length direction of the pipe body are formed in the front end of the pipe body.

[0015] Specifically, the camera is electrically connected with the adapter through a cable.

[0016] Compared with the prior art, the present application has the following advantages:

[0017] 1) The thoracic drainage tube of the present application embeds a miniature camera in the drainage tube, so that the catheterization process of the drainage tube can be performed under the guidance of real-time images. The real-time video image provided by the miniature camera helps the doctor to more clearly observe the internal structure of the chest cavity and accurately position the position of the drainage tube, reducing the risk of misoperation.

[0018] 2) The magnetic component embedded in the front end of the chest drainage tube of the present invention can respond to changes in the external magnetic field. Through the external magnetic field control system, the doctor can adjust the position of the drainage tube at any time during the operation to ensure that it achieves the best drainage effect.

[0019] 3) The chest drainage tube of the present invention helps to optimize the placement of the drainage tube through real-time observation and position adjustment functions, avoiding damage to surrounding important tissues and organs, thereby improving the efficiency and safety of drainage. The patient's postoperative recovery time can be shortened and the incidence of complications is significantly reduced.

[0020] 4) During the extubation process, the integrated micro-camera provides real-time video images, helping doctors accurately determine the timing and force of extubation, reducing patient discomfort and potential complications. The positioning function of the magnetic nanoparticles also facilitates a smoother extubation process. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments of the present invention may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0026] like Figure 1 As shown, in this embodiment, the tube body is Figure 1 At the right end, the drainage tube end 9 is inserted into the patient's body and is the front end of the drainage tube body of this embodiment; Figure 1 At the left end, the drainage tube connects to the external drainage bottle vial 8, representing the rear end of the drainage tube body in this embodiment. The drainage tube body 1 is made of flexible, biocompatible silicone or polyurethane material, suitable for long-term implantation. It is approximately 30 cm long, with an outer diameter of approximately 10 mm and an inner diameter of approximately 8 mm.

[0027] The chest drainage tube of this embodiment includes a tube body 1, wherein a mounting hole 11 extending along the length of the tube wall is provided in the tube wall of the tube body 1, the opening of one end of the mounting hole 11 is provided on the end face of the front end of the tube body 1, and the opening of the other end of the mounting hole 11 is close to the rear end of the tube body 1 and provided on the side wall of the tube body 1; a camera 2 located in the mounting hole 11 is provided at the front end of the tube body 1, and the camera 2 is provided toward the front end port of the tube body 1; a transfer port 3 located outside the tube body 1 is provided at the opening of the mounting hole 11 close to the rear end of the tube body 1, the signal output end of the camera 2 is electrically connected to the signal input end of the transfer port 3, and the camera 2 is electrically connected to the transfer port 3 via a cable 7. In order to increase the drainage efficiency of the drainage tube, a plurality of through holes 6 arranged along the length of the tube body 1 are provided at the front end of the tube body 1. A through hole 6 is provided on the opposite side, left side and right side of the camera 2, and the three through holes 6 are respectively located about 1 cm, 2.5 cm and 4 cm away from the tube opening of the tube body 1. The provision of the through holes 6 can increase the drainage efficiency of the drainage tube.

[0028] To more clearly visualize the patient's internal condition, light sources 4 embedded within the tube body 1 are located on either side of the camera 2. These light sources 4 are electrically connected to the signal input of the adapter 3. The miniature camera is fixed to the front end of the drainage tube body 1 and connected to an external display and control device via a thin cable.

[0029] The signal output end of the camera 2 is electrically connected to the adapter 3 located at the rear end of the tube body 1. After connecting the adapter 3 to the external display device, the patient's internal condition can be displayed on the external display device through the camera 2. Under the illumination of the light source 4, the camera 2 can more clearly reflect the patient's internal condition; the drainage tube placement process can be carried out under the guidance of real-time images. The real-time video image provided by the camera 2 helps the doctor observe the internal structure of the chest cavity more clearly and accurately locate the position of the drainage tube, reducing the risk of misoperation.

[0030] The camera 2 and light source 4 are not removable and are designed to be flattened to be embedded in the wall of the drainage tube. The camera is connected to the external adapter 3 via a thin cable 7. The camera 2, light source 4 and their related circuits are designed to be waterproof, fog-proof and insulated to ensure normal operation in a humid environment.

[0031] In order to better control the position of the drainage tube body 1 in the body outside the body, the front end of the tube body 1 is provided with a magnetic member 5 embedded in the tube wall of the tube body 1. The magnetic member 5 extends from the front end of the tube body 1 to the rear end of the tube body 1 along the length direction of the tube body 1. In order to increase the magnetism, the magnetic member 5 is evenly arranged along the circumferential direction of the tube body 1. The magnetic member 5 is made of nanomagnetic particles and the length of the magnetic member 5 is not less than 5 cm. Figure 1 As shown, nano-magnetic particles can be selected to be filled into the tube wall of the tube body 1, and the filling length of the nano-magnetic particles or the extension length of the magnetic member 5 is within the range of H in the figure.

[0032] The magnetic part 5 built into the wall of the tube body 1 will sense the external magnetic field. The external magnetic field can generate a variable magnetic field through an electromagnet or a magnet array controlled by a computer. According to the real-time image of the camera 2, the operator can adjust the direction and intensity of the magnetic field to achieve precise adjustment of the position of the drainage tube.

[0033] During use, after the operator connects the external display device, he can observe the position of the drainage tube and the situation in the chest cavity in real time during the catheterization process. As needed, a controllable external magnetic field source such as an electromagnet or a permanent magnet array is used to generate a magnetic field. The magnetic part 5 inside the tube body 1 will be induced by the external magnetic field. By controlling the direction of the external magnetic field, the front end of the tube body 1 will move in the direction of the external magnetic field, thereby guiding the positioning of the drainage tube, and combining the adjustment of the catheter length to place the drainage tube in the appropriate position. The external display device is equipped with a high-definition display and a video recording function to facilitate surgical recording and review. When the patient's condition is stable, the external display device can be disconnected to reduce unnecessary equipment at the patient's bedside and improve the equipment utilization of the external display device. Finally, the front-end camera of the drainage tube can be used to monitor the situation and clearly identify the extubation pointer, and provide real-time feedback on the extubation process.

[0034] The chest drainage tube of this embodiment integrates a micro-camera 2 and a magnetic component 5, allowing the tube placement process to be performed under real-time imaging guidance. The real-time video images provided by the micro-camera help doctors more clearly observe the internal structure of the chest cavity and accurately locate the position of the drainage tube, reducing the risk of misoperation.

[0035] The magnetic element 5 embedded in the front end of the drainage tube body 1 responds to changes in the external magnetic field to adjust the position of the drainage tube. Through this external magnetic field control system, the surgeon can adjust the position of the drainage tube at any time during surgery to ensure optimal drainage. This dynamic adjustment capability is difficult to achieve with traditional drainage technologies.

[0036] During the extubation process, the real-time video images provided by Camera 2 can help doctors accurately determine the timing and force of extubation, reducing patient discomfort and potential complications during extubation. The positioning function of Magnetic Component 5 can also facilitate a smoother extubation process. This helps reduce discomfort during both intubation and extubation, minimizes pain and trauma during the procedure, and enhances the patient's overall medical experience. Precise drainage placement and efficient drainage also contribute to faster patient recovery, reducing hospital stays and medical expenses.

[0037] The chest drainage tube of this embodiment integrates a camera 2 and a magnetic component 5 at the front end of the tube body 1, enabling real-time observation and position adjustment of the chest drainage tube. This has the advantages of improving tube placement accuracy, enabling real-time position adjustment, improving drainage efficiency and safety, facilitating the extubation process, providing a better patient experience, being compatible with multiple medical imaging technologies, facilitating remote operation and guidance, and conforming to the trend of intelligent modern medical equipment. This significantly improves the shortcomings of traditional chest drainage technology. These effects or features not only demonstrate the innovation and practicality of the present invention, but also highlight its potential advantages in practical applications.
