Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an external fixator for a drainage tube after breast cancer surgery. Background Art

[0002] After breast cancer surgery, a drainage tube is usually required to drain the accumulated fluid at the wound to promote wound healing. However, there are some problems with the current fixation methods of the drainage tube. In clinical work, patients after breast cancer surgery need to install a drainage tube to drain the accumulated fluid in the body or reduce the risk of infection.

[0003] However, traditional fixation methods are simple. For example, using adhesive tape, sutures, safety pins, etc. may cause the tube to be fixed too tightly or loosely, and even cause the drainage tube to fall off or cause trauma to the patient's skin. Moreover, if the drainage tube is fixed too tightly, when the patient moves, the drainage tube is strongly pulled, which is likely to cause the drainage tube to shift or fall out, affecting the drainage effect and even possibly causing complications such as wound infection; while if it is fixed too loosely, the stability of the drainage tube cannot be guaranteed. Therefore, corresponding improvements are made to solve this problem. Summary of the Invention

[0004] Based on the technical problems existing in the prior art, the present invention proposes an external fixator for a drainage tube after breast cancer surgery.

[0005] An external fixator for a drainage tube after breast cancer surgery proposed by the present invention includes a fixing plate. A pressing plate is fixed on the front surface of the fixing plate. The pressing plate has elasticity, and a sliding groove is opened on the front surface of the fixing plate. A slider is slidably connected in the sliding groove. A pushing plate is fixed on the top of the slider. One end of the pressing plate close to the pushing plate is upturned. A double-sided adhesive tape is provided on the back surface of the fixing plate. The pressing plate and the pushing plate are connected by a fixing component; according to the required quantity, a plurality of fixing plates are fixed to the patient's body through the double-sided adhesive tape. Then, the drainage tube is inserted from the upturned end of the pressing plate. Then, the pushing plate is pushed along the sliding groove towards the pressing plate. The pushing plate will push the drainage tube into the pressing plate. The pressing plate will deform and press and fix the drainage tube through elastic force. And when the drainage tube is strongly pulled, the drainage tube can still move and will not be fixed dead by the pressing plate.

[0006] Preferably, the fixing component includes a clamping strip and a plurality of clamping grooves that can be clamped and matched with the clamping strip. The clamping grooves are opened on the back surface of the pressing plate, and the clamping strip is arranged on the front surface of the pushing plate; when the pushing plate is pushed into the pressing plate, the clamping strip will be clamped with a corresponding clamping groove, thereby realizing the fixation of the pushing plate. Pull the end of the pressing plate up a little more to make the clamping strip and the clamping groove disengage from the clamped state, and the pushing plate can be directly pulled out. The use process is very convenient.

[0007] Preferably, the fixing component includes a screw rod which is rotatably connected to the fixing plate, and the screw rod is in threaded connection with the slider. A notch is formed at the edge of the fixing plate, and the end of the screw rod extends into the notch. By rotating the screw rod at the notch, the slider can be driven to move along the direction of the sliding groove, and when the push plate moves to a predetermined position, it is directly fixed at that position.

[0008] Preferably, the number of the double-sided adhesive strips is two, and the shape of the double-sided adhesive strips is arc-shaped. A circular central convex layer is provided on the back of the fixing plate. The double-sided adhesive strips surround the edge of the central convex layer. The thickness of the double-sided adhesive strips is greater than that of the central convex layer, and a gap is left between the two double-sided adhesive strips. In this way, when the fixing plate is fixed to the patient's body, the central convex layer and the patient's skin will not be in direct contact, forming a space that can ventilate through the gap, so as to reduce the discomfort of the skin caused by long-term wearing.

[0009] Preferably, it further includes a pressure acquisition module, a sediment acquisition module, a control module, a battery module and an actuator. The pressure acquisition module is used to detect the pressure information in the drainage tube in real time. The sediment acquisition module is used to detect the sediment information attached to the wall of the drainage tube in real time. The control module receives the data collected by the pressure acquisition module and the sediment acquisition module in real time and generates an evaluation coefficient, compares it with a preset reference threshold, and controls the working state of the actuator according to the comparison result. During the drainage process, the control module will receive the data collected by the pressure acquisition module and the sediment acquisition module in real time, conduct comprehensive analysis, and then generate an evaluation coefficient. By comparing the evaluation coefficient with the preset evaluation coefficient reference threshold, it is judged whether the amount of sediment attached to the wall of the drainage tube is within a reasonable range, and the working state of the actuator is controlled according to the comparison result. If the amount of sediment attached to the wall of the drainage tube is not within a reasonable range, the actuator will be activated to clean the sediment, thus avoiding the blockage of the drainage tube.

[0010] Preferably, the actuator is a vibrator. An installation frame for installing the vibrator is provided on the front surface of the pressing plate. Rubber strips for pressing against the vibrator are respectively fixedly connected to the inner walls on both sides of the installation frame. In this way, the vibrator can be placed into the installation frame, and then the vibrator is pressed between the two rubber strips, so that the vibrator can be fixed by the rubber strips. After receiving the relevant instructions from the control module, the vibrator will vibrate, thus cleaning the sediment attached to the wall of the drainage tube.

[0011] Preferably, the input end and the output end of the pressure acquisition module are electrically connected to the output end and the input end of the control module respectively, the input end and the output end of the sediment acquisition module are electrically connected to the output end and the input end of the control module respectively, the output end of the control module is electrically connected to the input end of the vibrator, the battery module is used to supply power to the pressure acquisition module, the sediment acquisition module and the vibrator, and the battery module and the control module are integrated together.

[0012] Preferably, after receiving the data collected by the sediment acquisition module, the control module generates a sediment adhesion index (S):

[0013]

[0014] Wherein, : The covered area of the sediment on the pipe wall, : The cross-sectional area of the drainage pipe, : The average thickness of the sediment, : The preset maximum allowable thickness;

[0015] After receiving the data collected by the pressure acquisition module, the control module generates a pressure fluctuation coefficient (P):

[0016]

[0017] Wherein, : The real-time pressure, : The initial reference pressure.

[0018] Preferably, the evaluation coefficient (K):

[0019]

[0020] Wherein, : The dynamic weight factor.

[0021] Preferably, the control logic of the control module for the working state of the actuator according to the comparison result is as follows:

[0022] When And the duration When, the actuator starts the vibration mode;

[0023] Wherein, : The threshold value, : The minimum trigger time.

[0025] 1. An external fixator for a drainage tube after breast cancer surgery. This external fixator for a drainage tube after breast cancer surgery can tightly fix the drainage tube through the cooperation of a fixed plate, an elastic pressing plate, and a pushing plate. When the drainage tube is strongly pulled, the drainage tube can still move and will not be fixedly held, ensuring the stability of the drainage tube under normal circumstances and avoiding problems such as displacement or prolapse caused by pulling, thus improving the safety and effectiveness of drainage.

[0026] 2. An external fixator for a drainage tube after breast cancer surgery provides two different fixing components. The cooperation of the card strip and the card slot makes the fixing and disassembly operations of the pushing plate simple and convenient, facilitating adjustment by medical staff according to actual situations; the threaded connection method between the screw rod and the slider enables the slider to be driven to move by rotating the screw rod, and the pushing plate can be directly fixed after moving to the predetermined position, further enhancing the stability and operability of the fixation.

[0027] 3. An external fixator for a drainage tube after breast cancer surgery is provided with a pressure acquisition module, a sediment acquisition module, and a control module, which can detect the pressure information and the sediment information on the tube wall inside the drainage tube in real time and generate an evaluation coefficient. By comparing with a pre-set reference threshold, it is judged whether the amount of sediment attached to the tube wall of the drainage tube is within a reasonable range. If not, the control module will control the vibrator to start and clean the sediment, avoiding blockage of the drainage tube pipeline, reducing the inspection and treatment work of medical staff, and also alleviating the pain of patients.

The clamping grooves 8 are formed on the back surface of the pressing plate 2, and the clamping strip 9 is arranged on the front surface of the pushing plate 3;

[0042] During use, when the pushing plate 3 is pushed into the pressing plate 2, the clamping strip 9 will be clamped with a corresponding clamping groove 8, thereby realizing the fixation of the pushing plate 3. Pull the end of the pressing plate 2 upward a little more to make the clamping strip 9 and the clamping groove 8 out of the clamped state, and the pushing plate 3 can be directly pulled out. The use process is very convenient.

[0043] Refer to Figure 3 and Figure 6 , in Embodiment 2, the fixing component includes a screw rod 11. The screw rod 11 is rotatably connected to the fixed disk 1, and the screw rod 11 is threadedly connected to the slider 5. A notch 10 is formed at the edge of the fixed disk 1, and the end of the screw rod 11 extends into the notch 10;

[0044] During use, by rotating the screw rod 11 at the notch 10, the slider 5 can be driven to move along the direction of the sliding groove 4 by the screw rod 11, and when the pushing plate 3 moves to a predetermined position, it is directly fixed at this position.

[0047] In Embodiment 3, a breast cancer postoperative drainage tube external fixator further includes a pressure acquisition module 12, a sediment acquisition module 13, a control module 15, a battery module 16 and an actuator. The pressure acquisition module 12 is used to detect the pressure information in the drainage tube in real time.

The control module 15 receives the data collected by the pressure acquisition module 12 and the sediment acquisition module 13 in real time and generates an evaluation coefficient, compares it with a preset reference threshold, and controls the working state of the actuator according to the comparison result;

[0048] It should be noted that the pressure acquisition module 12 can be a sandwich structure sensor or other devices capable of detecting the pressure information in the drainage tube in real time. The sediment acquisition module 13 can be an annular sensing unit or other devices capable of detecting the sediment information attached to the inner wall of the drainage tube in real time. The control module 15 is an embedded MCU (ARM Cortex-M4), which runs an adaptive PID algorithm to adjust the α / β weight. Therefore, the pressure acquisition module 12, the sediment acquisition module 13, and the control module 15 are not specifically defined here and can be selected according to actual needs;

[0049] During use, in the process of drainage, the control module 15 will receive the data collected by the pressure acquisition module 12 and the sediment acquisition module 13 in real time, perform comprehensive analysis, and then generate an evaluation coefficient. By comparing the evaluation coefficient with a pre-set evaluation coefficient reference threshold, it is judged whether the amount of sediment attached to the inner wall of the drainage tube is within a reasonable range, and the working state of the actuator is controlled according to the comparison result. If the amount of sediment attached to the inner wall of the drainage tube is not within a reasonable range, the actuator will be activated to clean the sediment, thus avoiding blockage of the drainage tube.

[0050] Among them, the actuator is a vibrator 14. The front surface of the pressing plate 2 is provided with a mounting frame 17 for mounting the vibrator 14. The inner walls of both sides of the mounting frame 17 are respectively fixedly connected with rubber strips 18 for pressing against the vibrator 14;

[0051] During use, the vibrator 14 can be placed into the mounting frame 17, and then the vibrator 14 is pressed between the two rubber strips 18, so that the vibrator 14 can be fixed by the rubber strips 18. After receiving the relevant instructions from the control module 15, the vibrator 14 will vibrate, thus cleaning the sediment attached to the inner wall of the drainage tube.

The battery module 16 is used to supply power to the pressure acquisition module 12, the sediment acquisition module 13, and the vibrator 14, and the battery module 16 and the control module 15 are integrated together.

[0053] In Embodiment 4, through the cooperation between the pressure acquisition module 12, the sediment acquisition module 13, the control module 15, and the actuator, the control logic for intelligently cleaning the sediment attached to the inner wall of the drainage tube is specifically as follows:

[0054] 1. Core control process: Sensor data acquisition → Parameter standardization → Evaluation coefficient calculation → Threshold judgment → Actuator trigger → Feedback calibration.

[0055] 2. Standardized calculation formula for key parameters:

[0056] After receiving the data collected by the sediment collection module 13, the control module 15 generates the sediment adhesion index (S):

[0057]

[0058] Wherein, : Area of the sediment covering the pipe wall (mm²), Cross-sectional area of the drainage pipe (mm²), : Average thickness of the sediment (mm), : Preset maximum allowable thickness (mm);

[0059] After receiving the data collected by the pressure collection module 12, the control module 15 generates the pressure fluctuation coefficient (P):

[0060]

[0061] : Real-time pressure (kPa), : Initial reference pressure (kPa).

[0062] Wherein, the evaluation coefficient (K):

[0063]

[0064] The dynamic weight factors α and β are obtained by fitting historical data and satisfy:

[0065]

[0066] Wherein, : Dynamic weight factor (range 0.1 - 0.9, default α = 0.6, β = 0.4);

[0067] The selection basis of the dynamic weight factors (α = 0.6, β = 0.4) is as follows:

[0068] Basis for weight distribution: The contribution degree of each parameter to the sediment adhesion index (S) is determined by the principal component analysis method, and the optimal ratio is obtained through regression verification of clinical data. Engineering verification: The distribution of 0.6 / 0.4 reduces the false alarm rate of the system to less than 5% in the in vitro simulation experiment (the control group is 12%);

[0069] Fault tolerance mechanism: Set the sum of weights Σ = 1 to ensure the existence of a constraint relationship between parameters and avoid a single parameter dominating the system judgment.

[0070] 3. Execution trigger conditions:

[0071] When and the duration When it is, the actuator starts the vibration mode;

[0072] Among them, : Threshold value (default 0.75), : Minimum trigger time (default 30 seconds);

[0073] : The selection basis of the threshold value (default 0.75) is as follows:

[0074] Hydrodynamics model: Derived based on the Navier-Stokes equation, when the pressure fluctuation coefficient exceeds 0.75, the turbulence risk increases by 87%;

[0075] Clinical statistics: Analyzing 200 cases of postoperative drainage data, it is found that when the pressure fluctuation exceeds this threshold value, the catheter blockage probability increases by 3.2 times;

[0076] Safety margin: Reserve a 25% buffer range to cope with the influence of sensor measurement error (±5%) and environmental temperature fluctuation.

[0077] : The selection basis of the minimum trigger time (default 30 seconds) is as follows:

[0078] Nerve reflex cycle: Refer to the human pain conduction speed (1-2m / s) to ensure that the intervention measure is completed before the nociceptive stimulus conducts to the spinal cord;

[0079] Material creep characteristics: Based on the stress relaxation curve of medical silicone tubes, 93% of abnormal deformations can be captured in a 30-second window period;

[0080] System response verification: The full-cycle test from sensor sampling to actuator action shows that a 30-second period can achieve a 98.7% reliable response.

[0081] 4. Feedback learning:

[0082] After the vibration is cleared, it enters the learning mode, records the clearing effect and corrects the value, and the correction formula is:

[0083]

[0084] Among them, γ is the learning rate (0.05 - 0.2), which represents the response sensitivity of the control system to the change of the drainage state, is the step coefficient of weight update in the adaptive algorithm, and the value range of 0.05 - 0.2 is verified by fluid dynamics simulation to ensure that the system maintains Lyapunov stability during the dynamic adjustment process, and ΔQ is the percentage increase in drainage efficiency (drainage efficiency gradient), and the calculation formula:

[0085]

[0086] Among them, is the reference drainage efficiency (set according to ISO5367 standard), is the real-time monitored value, and when ΔQ≥5%, the parameter tuning module of the PID controller is triggered.
