Description

Technical Field

[0001] The present invention relates to the technical field of drainage equipment, and in particular to a drainage equipment for breast surgery. Background Art

[0002] Breast surgery is an important means of treating benign and malignant breast diseases, including radical mastectomy, breast-conserving surgery, breast reconstruction, benign breast tumor resection, and breast abscess drainage. Postoperative wounds are often accompanied by exudation of tissue fluid, blood or lymph. If effective drainage is not achieved, it may lead to complications such as seroma, hematoma, infection, etc., affecting wound healing and even increasing patient pain and the risk of secondary surgery. Currently, the widely used drainage devices mainly include basic components such as drainage tubes, connecting sleeves, drainage bottles or drainage bags.

[0003] However, the existing drainage devices have significant technical defects in actual use. First, medical staff can only evaluate postoperative recovery by regularly observing the color, turbidity and amount of the drainage fluid with the naked eye. This subjective judgment method is prone to misjudgment due to untimely observation or experience differences. Secondly, for abnormal changes such as sudden appearance of bloody fluid or purulent secretions in the drainage fluid, the existing drainage devices also lack automatic recognition and alarm mechanisms. It is also necessary to wait for medical staff to observe regularly before discovering abnormalities, which may delay the best time for clinical intervention. Therefore, the present application provides a drainage device for breast surgery to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a drainage device for breast surgery to solve the problem that the existing drainage devices rely on the clinical experience of medical staff and can only observe the status of the drainage fluid regularly and cannot detect abnormalities in time.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A drainage device for breast surgery comprises a drainage can, a drainage joint and a drainage tube, wherein the drainage tube is sleeved on the outside of the drainage joint on the top cover of the drainage can, the top cover of the drainage can is provided with a monitor located on the outside of the drainage joint, the outside of the monitor is provided with a control module and an alarm, the outside of the control module is fixedly connected with a fixing frame and a light shielding frame, the fixing frame is equipped with a light source, and the outside of the light shielding frame is provided with an optical sensor that cooperates with the light source; a fixing component is used to fix the relative position of the optical sensor and the light source, and the fixing component is connected to the light shielding frame; a focusing component is used to reduce the interference of external light on the operation of the light source and the optical sensor, and the focusing component is connected to the light shielding frame.

[0007] Optionally, suction cups are symmetrically installed on the bottom of the monitor, and a battery electrically connected to the control module is provided in the monitor.

[0008] Optionally, an opening is provided on a side of the light shielding frame away from the light source, and an end of the opening is bent toward the outside of the light shielding frame.

[0009] Optionally, the exterior of the light shielding frame is provided with symmetrically distributed first weakening grooves, and the opening of the light shielding frame is provided with a positioning groove.

[0010] Optionally, the fixing assembly includes a fixing belt and a Velcro surface respectively fixedly connected to both ends of the light shielding frame, and a Velcro surface is provided on a side of the fixing belt facing the Velcro surface.

[0011] Optionally, the outer movable sleeve of the fixing belt is provided with a movable seat, the optical sensor is fixedly mounted on the outer surface of the movable seat facing the light source, and the movable seat is further provided with a through opening adapted to the size of the fixing belt.

[0012] Optionally, a paddle is symmetrically mounted on a surface of the movable seat away from the light source, the paddle is perpendicular to the movable seat, and evenly distributed friction lines are provided on the paddle.

[0013] Optionally, the light source and the optical sensor are connected to the control module via lines, and a limiting opening for accommodating the passage of the lines is provided on the fixing belt.

[0014] Optionally, the focusing assembly includes a condenser mounted on the inner wall of the light shielding frame, and the position of the condenser corresponds to the monitoring position of the light source and the optical sensor.

[0015] Optionally, a rubber ring is fixedly connected to the outer side of the optical sensor and the position on the inner side wall of the light-shielding frame corresponding to the condenser. The rubber ring is trumpet-shaped, and a hollow annular edge is provided at the end of the rubber ring. A second weakening groove is provided on the outside of the rubber ring.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up a light source and an optical sensor as well as a control module and an alarm, when the entire drainage equipment is working, the light emitted by the light source can be continuously monitored by the optical sensor, and the transmittance of the drainage tube can be used to judge whether there is any abnormality in the accumulated fluid drained in the drainage tube. Once an abnormality in the accumulated fluid is found, the control module will control the alarm to sound an alarm to alert medical staff and patients, without having to wait for medical staff to observe regularly, thereby avoiding delaying the best time for clinical intervention.

[0018] By setting up a light-shielding frame and a fixing component, the light-shielding frame can be fixed around the outside of the drainage tube under the action of the fixing component. On the one hand, the connection and fixing effect between the drainage tube and the drainage joint is strengthened. On the other hand, the light-shielding frame can also cooperate with the fixing component to surround the outside of the monitoring area of ​​the drainage tube, thereby shielding light and reducing external interference during the operation of the light source and the optical sensor.

[0019] By setting the first weakened groove, movable seat and through-opening on the light-shielding frame, the light-shielding frame can be deformed at the first weakened groove under the traction of the fixed component to adapt to drainage tubes of different specifications. The positions of the movable seat and the optical sensor can also be changed accordingly on the fixed belt, thereby improving the overall adaptability range of the equipment and can be used on drainage tubes of different specifications.

[0020] By setting a condenser in the focusing assembly, the condenser, the light-emitting position of the light source and the detection position of the optical sensor are on the same straight line. The condenser can further converge the light emitted by the light source to a position corresponding to the detection area of ​​the optical sensor, allowing the optical sensor to more easily detect the transmittance of the accumulated fluid in the drainage tube, thereby ensuring the real-time monitoring effect of the drainage equipment.

[0021] By setting a rubber ring in the focusing assembly, after the light-shielding frame and the fixing assembly are wrapped around the outside of the drainage tube, the rubber ring is squeezed by the drainage tube and deformed, and maintains contact with the outside of the drainage tube. On the one hand, the gap between the drainage tube and the light-shielding frame is closed, further reducing the interference of external light on the monitoring work of the optical sensor. On the other hand, it also avoids excessive squeezing of the drainage tube by the light-shielding frame and the fixing assembly, which affects the passage of accumulated fluid in the drainage tube, and further improves the technical solution of the entire equipment.

[0041] like Figures 1 to 10As shown, an embodiment of the present invention provides a drainage device for breast surgery, including a drainage can 1, a drainage joint 2 and a drainage tube 3. The drainage tube 3 is sleeved on the outside of the drainage joint 2 on the top cover of the drainage can 1. The drainage can 1 is used to store the accumulated fluid drained from the patient's surgical area by the drainage tube 3. During actual use, the vertical drainage joint 2 on the top cover of the drainage joint 2 is connected to the drainage tube 3, and the drainage tube 3 is inserted into the drainage hole opened in the patient's surgical area to drain the accumulated fluid. A bend is also provided on the top cover of the drainage can 1 for connecting to a negative pressure device. When the negative pressure device is working, negative pressure is generated in the drainage can 1 to promote the drainage work. A monitor 4 is provided on the top cover of the drainage can 1 and is located on the outside of the drainage joint 2. A control module 5 and an alarm 11 are provided on the outside of the monitor 4. A fixing frame 7 and a light shielding frame 8 are fixedly connected to the outside of the control module 5. A light source 9 is installed in the fixing frame 7. An optical sensor 18 cooperating with the light source 9 is provided on the outside of the light shielding frame 8. The control module 4 on the outside of the monitor 4 5 can work in conjunction with the light source 9 and the optical sensor 18 to continuously monitor the effusion passing through the drainage tube 3 in real time. The optical sensor 18 determines whether the drained effusion has any abnormality based on the transmittance of the light emitted by the light source 9. The light source 9 uses a 600-700nm constant current LED light source to reduce interference from hemoglobin absorption. The optical sensor 18 uses a photodiode or a phototransistor. Under normal conditions, the transmittance is greater than 70%. When there is a mild abnormality, the transmittance is 50% to 70%, which may be an early infection or a small amount of bleeding. When there is a significant abnormality, the transmittance is less than 50%. Once the optical sensor 18 detects a significant abnormality, the control module 5 controls the alarm 11 to operate, causing the alarm 11 to sound an alarm, promptly alerting the patient and medical staff, thereby avoiding delaying the optimal time for clinical intervention. The principles and working methods of the above-mentioned control module 5, light source 9, alarm 11 and optical sensor 18 are the same as those in the prior art and will not be described in detail here.

[0042] A suction cup 6 is symmetrically installed at the bottom of the monitor 4, and a battery electrically connected to the control module 5 is provided in the monitor 4. The drainage can 1 is usually a disposable item. In order to ensure the stability of the monitor 4 as a whole during operation, a suction cup 6 is provided at the bottom of the monitor 4. The monitor 4 as a whole can be fixed on the top cover of the drainage can 1 by adsorption through the suction cup 6. After the drainage can 1 is used, the drainage can 1 is discarded, and the monitor 4 can be removed and reused. The control module 5 on the monitor 4 can store electrical energy for supplying the control module 5, the light source 9 and the optical sensor 18. When the external line cannot be connected, the wireless power supply working mode is adopted, so that the whole set of equipment can adapt to a wider range of use environments; a fixed component is used to fix the relative position of the optical sensor 18 and the light source 9, and the fixed component is connected to the light shielding frame 8. The drainage tube 3 in different drainage devices The specifications are different, and the degree of fit between the light shielding frame 8 and the drainage tube 3 after it is wrapped around the outside of the drainage tube 3 is also different. Therefore, a fixing component is provided to pull the light shielding frame 8 to deform, so as to adapt to drainage tubes 3 of different specifications, and while fixing the light shielding frame 8, the position of the optical sensor 18 is also fixed, so that after the light shielding frame 8 is deformed, the position of the optical sensor 18 can correspond to the position of the light source 9, ensuring the normal progress of the monitoring work; the focusing component is used to reduce the interference of external light on the work of the light source 9 and the optical sensor 18. The focusing component is connected to the light shielding frame 8. The setting of the focusing component can concentrate the light emitted by the light source 9 and form a shielding in the area where the light is irradiated and received outside the drainage tube 3, reducing the interference of external ambient light, ensuring the accuracy of the optical sensor 18 when working, and improving the technical solution of the entire drainage equipment.

[0043] In this embodiment, if Figures 3 to 5As shown, an opening is provided on the side of the light shielding frame 8 away from the light source 9, and the end of the opening is bent toward the outside of the light shielding frame 8. A symmetrically distributed first weakening groove 16 is provided on the outside of the light shielding frame 8, and a positioning groove 14 is provided at the opening of the light shielding frame 8. The position of the positioning groove 14 corresponds to the position of the fixing component, which is used to assist in positioning the fixing component when in use. The opening of the first weakening groove 16 makes the light shielding frame 8 thinner and weaker at the first weakening groove 16, and is more likely to deform after being subjected to external force. The opening provided on the light shielding frame 8 makes the light shielding frame 8 as a whole a circular ring structure that is broken at the opening position, so that the light shielding frame 8 as a whole can be installed from the outside of the drainage tube 3 after being connected to the drainage joint 2. The end of the opening of the light shielding frame 8 is bent outward so as to further increase the size of the opening. The light shielding frame 8 can be more easily mounted on the outside of the drainage tube 3. During the process of the light shielding frame 8 being mounted on the outside of the drainage tube 3, it is squeezed from the outside of the drainage tube 3 and bent and deformed at the first weakened groove 16, making the opening of the light shielding frame 8 larger until the light shielding frame 8 is completely mounted on the outside of the drainage tube 3. After that, the light shielding frame 8 recovers under the action of its own elastic force. At this time, on the one hand, the light shielding frame 8 surrounds the outside of the drainage tube 3, and the opening is also blocked by the structure of the fixing component, which can reduce the interference of external light on the working environment of the optical sensor 18 and the light source 9 to a certain extent. On the other hand, the cooperation between the light shielding frame 8 and the fixing component also forms an auxiliary clamping of the drainage tube 3, thereby enhancing the stability of the connection between the drainage tube 3 and the drainage connector 2, and avoiding the risk of the connection falling off during the drainage process.

[0044] In this embodiment, if Figures 3 to 6 As shown, the fixing assembly includes a fixing belt 10 and a Velcro surface 17 respectively fixedly connected to the two ends of the shading frame 8, a Velcro fur surface is provided on the side of the fixing belt 10 facing the Velcro surface 17, a movable seat 15 is provided on the outer movable sleeve of the fixing belt 10, an optical sensor 18 is fixedly mounted on the outer side of the movable seat 15 facing the light source 9, and a through-hole 20 adapted to the size of the fixing belt 10 is also provided on the movable seat 15, the two ends of the shading frame 8 are respectively fixedly connected to the fixing belt 10 and the Velcro surface 17, and the Velcro surface 17 is completely fixedly connected to the shading frame 8. On the outside of one end, the fixing belt 10 is fixedly connected to the other end of the light-shielding frame 8, and the end of the fixing belt 10 extends to the outside of the light-shielding frame 8. When the light-shielding frame 8 is squeezed so that the light-shielding frame 8 and the outside of the drainage tube 3 are kept in contact, the fixing belt 10 can be pulled so that the fixing belt 10 is wrapped around the outside of the light-shielding frame 8 and contacts and fits with the Velcro sticky surface 17, thereby forming a limited fixation for the light-shielding frame 8, allowing the light-shielding frame 8 and the fixing belt 10 to wrap around the outside of the drainage tube 3, while assisting in fixing the connection between the drainage tube 3 and the drainage joint 2, forming a light shielding for the monitoring area on the drainage tube 3.

[0045] A paddle 19 is symmetrically mounted on the side of the movable seat 15 away from the light source 9. The paddle 19 and the movable seat 15 are perpendicular to each other. The paddle 19 is provided with evenly distributed friction lines. The light source 9 and the optical sensor 18 are connected to the control module 5 through a line. A limit opening 13 is provided on the fixing belt 10 to accommodate the passage of the line. The opening of the limit opening 13 can facilitate the movement of the movable seat 15 and the optical sensor 18 and the fixing belt 10 when relative displacement occurs. At the same time, it prevents the connection line between the optical sensor 18 and the control module 5 from affecting the shielding and clamping effect of the light-shielding frame 8 on the outside of the drainage tube 3. The light-shielding frame 8 changes its external shape. While the shape is adapting to the outside of the drainage tube 3, the relative position of the fixing belt 10 and the other end of the light-shielding frame 8 will also change, which will cause the relative position of the movable seat 15 on the fixing belt 10 and the light-shielding frame 8 to change. By pinching the paddle 19 on the movable seat 15 and exerting force along the fixing belt 10, the movable seat 15 can be slid on the outside of the fixing belt 10, changing the relative position between the fixing belt 10 and the movable seat 15 until the optical sensor 18 on the movable seat 15 corresponds to the position of the light source 9. At this time, the position of the light-shielding frame 8 and the optical sensor 18 is fixed by relying on the adhesion between the fixing belt 10 and the Velcro surface 17.

[0046] In this embodiment, if Figures 5 to 10As shown, the focusing assembly includes a condenser 21 mounted on the inner wall of the light-shielding frame 8, and the position of the condenser 21 corresponds to the monitoring position of the light source 9 and the optical sensor 18. The setting position of the condenser 21 corresponds to the light emission position of the light source 9, and can focus the light emitted by the light source 9 to the position of the optical sensor 18 to avoid light scattering affecting the monitoring accuracy, so that the optical sensor 18 can continuously monitor the light emitted by the light source 9, thereby judging whether there is any abnormality in the effusion passing through the drainage tube 3. The outside of the optical sensor 18 and the position on the inner wall of the light-shielding frame 8 corresponding to the condenser 21 are fixedly connected with a rubber ring 12. The rubber ring 12 is trumpet-shaped, and a hollow annular edge 22 is provided at the end of the rubber ring 12. A second weakening groove 23 is provided on the outside of the rubber ring 12. The hollow structure of the annular edge 22 causes the rubber ring 12 to be squeezed from the drainage tube 3 at the annular edge 22. Afterwards, deformation can occur at the annular edge 22, and the second weakened groove 23 is also thinned at the second weakened groove 23 on the rubber ring 12, making the rubber ring 12 more easily deformable as a whole. When the light shielding frame 8 and the optical sensor 18 are fixed under the action of the fixing assembly, the inner wall of the light shielding frame 8 and the rubber ring 12 outside the optical sensor 18 are squeezed and fitted to the outside of the drainage tube 3. The rubber ring 12 that is squeezed and deformed by the drainage tube 3 can fill the gap between it and the drainage tube 3, further blocking the illumination area of ​​the light source 9 on the drainage tube 3, and isolating it from interference from external light. At the same time, the elastic material of the rubber ring 12 combined with the structural design of the annular edge 22 and the second weakened groove 23 can prevent the light shielding frame 8 and the fixing assembly from excessively squeezing the drainage tube 3 after being clamped and fixed on the outside of the drainage tube 3, resulting in the drainage function of the drainage tube 3 being affected, thereby ensuring the normal operation of the drainage tube 3.

[0047] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
