Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a pipeline protection device capable of intelligent follow-up during dialysis. Background Art

[0002] During dialysis treatment, patients often feel sleepy due to a variety of complex factors. Taking chronic renal failure as an example, the disease itself causes a large amount of metabolic waste and excess water to accumulate in the body, which seriously interferes with the normal function of the nervous system. At the same time, some drugs used in dialysis treatment, such as antihypertensive drugs and sedatives, have obvious side effects of drowsiness. In addition, the dialysis process consumes a lot of the patient's physical strength and energy, leaving the body in a state of excessive fatigue. These factors are intertwined, causing patients to easily fall asleep during dialysis.

[0003] Patients who are sleeping often unconsciously turn over or sideways. However, existing dialysis tubing and puncture needles do not have the function of automatically adapting to limb movements. Once the patient turns over or sideways, the dialysis tubing on the arm is very likely to be pulled or squeezed. This will not only cause the tubing to bend and clog, seriously hindering blood flow and affecting the dialysis effect, but may even cause serious consequences such as blood coagulation in the tubing. At the same time, the puncture needle is also prone to displacement or dislocation due to the patient's movements, which will not only damage the blood vessels, cause local bleeding and hematoma, but also greatly increase the risk of infection.

[0004] At present, the existing technology mainly uses two methods to deal with the impact of patient movements on dialysis tubing. One is to use bendable or flexible dialysis tubing to adapt to the patient's slight movements to a certain extent, reducing the risk of tubing bending and blockage; the second is to use fixing stickers, fixing belts and other devices to fix the dialysis catheter on the patient's body, so that it remains relatively stable when the patient is moving, reducing displacement and pulling. However, it should be pointed out that these two methods can only deal with the patient's relatively slight and gentle movements. When the patient is in a dialysis coma, the pulling force on the dialysis tube and the squeezing force on the dialysis puncture site are often large, and these improvement measures in the existing technology are difficult to effectively resist. Therefore, the development of a device that can achieve real-time movement of the dialysis tubing and the patient's body when the patient is comatose and the body turns over, and at the same time effectively protect the puncture point, has become an important problem that needs to be solved urgently. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a pipeline protection device with intelligent follow-up during dialysis. By setting up a pipeline adaptive protection unit composed of a dynamic follow-up control module and a puncture point rigid isolation structure, a real-time action compensation unit composed of a position sensing and tensile force detection module and an intelligent response algorithm, a pipeline shape maintenance unit composed of an anti-bending guiding mechanism and an elastic buffer layer, a puncture protection unit for synchronous fixation and pressure monitoring of the puncture point, a modular installation system supporting multi-scenario adaptation, and an intelligent control center integrating abnormal warning and data linkage, the problems in the prior art such as pipeline bending and puncture point displacement caused by the patient's turning over, the inability of traditional fixing devices to adapt to the dynamic changes of limb movements, the direct transmission of pipeline pulling force to the puncture area leading to complications, and the lack of real-time protection and intelligent response mechanism are solved.

[0010] Further, air inflation fixing sleeves for flexibly fixing the patient's arm are arranged on the inner sides of both the upper arm sleeve and the lower arm sleeve.

[0011] Further, the dialysis tube follow-up retractor includes a housing body. Dialysis tube ports are provided on the lower left side and the upper right side of the housing body.

A dialysis tube electric roller for rolling and retracting the dialysis tube is fixedly provided inside the housing body.

[0012] Further, spring steel protective sleeves are fixedly provided at the tops of the sealing clamp and the pipeline electric clamp to prevent the dialysis tube from being bent and blocked at the interface.

[0016] By integrating dynamic follow-up control and puncture point rigid isolation technology, the present invention realizes real-time adaptive adjustment of the pipeline and the limb during the dialysis process of the patient, effectively avoiding the risks of pipeline bending, pulling and puncture point displacement caused by turning over actions.

[0017] The device is built-in with multiple protection mechanisms, combined with adaptive pressure regulation and pipeline anti-bending design, automatically maintaining the pipeline patency and puncture point stability during the patient's movement, significantly reducing the need for manual intervention. The intelligent monitoring module real-time feedbacks the patient's physical signs and pipeline status, and immediately triggers an alarm and links with the dialysis equipment in case of abnormal conditions, ensuring the safety of the dialysis process. In addition, the modular design supports rapid installation and maintenance, adapts to patients of different body types, and improves the clinical operation efficiency. This solution provides a safe and comfortable dialysis experience for patients through electromechanical collaborative control and intelligent protection technology, while reducing the workload of medical staff.

[0065] Stability Test: Apply an external force to simulate the patient's movements, observe whether the electromagnetic adsorption fixing base 1 has no displacement, and use a vibration sensor to detect whether the vibration amplitude of the base is within the allowable range.

[0066] Installation and Calibration of the Electric Telescopic Suspension Bracket 3

[0067] Robotic Arm Installation: Connect the nested telescopic arm 301 to the bottom of the central controller 2 through a flange, and check whether the nested gap of the carbon fiber telescopic arm is ≤0.1mm.

[0068] Servo Motor Debugging: Drive the servo motor through the central controller 2, test the vertical telescoping and horizontal movement functions of the telescopic arm, and use a laser rangefinder to calibrate the stroke accuracy (error ±1mm).

[0069] Dynamic Response Test: Simulate the patient's turning over action to verify whether the telescopic arm can adjust its position in real time following the signal of the position inductor 7.

[0070] Installation and Function Verification of the Dialysis Tube Follow-up Reel 4

[0071] Fixing of the outer housing 401: Fix the outer housing 401 to the end of the electric telescopic suspension bracket 3 with bolts to ensure that the dialysis tube orifice is aligned with the pipeline direction.

[0072] Debugging of the roller 402:

[0073] Install the roller 406 and cover it with a high-friction rubber layer 407, and check that the surface of the rubber layer has no cracks or wear.

[0074] Connect the power supply of the stepping motor and test the forward and reverse rotation functions of the roller. Set the rotation speed range to 5 - 15 cm / s.

[0075] Calibration of the tensile force sensor 408:

[0076] Apply a preset tensile force (0 - 20 N) using a standard weight, and adjust the output signal of the strain gauge sensor to ensure that the linear error ≤ ±1%.

[0077] Enter the calibration data into the central controller 2 to establish a tensile force - rotation speed control curve.

[0078] Adjustment of the guide roller 409: Adjust the angle of the guide roller to ensure that the outlet direction of the dialysis tube is smooth and the bending radius ≥ 8 cm.

[0079] Wearing and Function Testing of the Puncture Point Protective Arm Sleeve 5

[0080] Wearing the arm sleeve: Unfold the upper arm sleeve 501 and the lower arm sleeve 502, adjust the opening and closing angle through the rotating shaft 504, and fix it to the patient's arm using the buckle 505.

[0081] Pressure setting of the inflatable fixing sleeve 503: Start the air pump to inflate to the preset pressure (0.1 - 0.3 kPa), monitor the pressure stability through the pressure sensor 507, and trigger automatic pressure relief when the limit is exceeded.

[0082] Inspection of the puncture needle observation window 506: Turn on the LED fill light, observe the position of the puncture needle through the transparent window, and verify the field of view clarity and no distortion.

[0083] Connection and Isolation Verification of the Anti-Pulling Dialysis Tube Connector 6

[0084] Pipeline connection: Connect the dialysis fluid inlet pipe orifice 602 to the dialysis machine pipeline, and connect the puncture needle orifice 603 to the patient's blood vessel puncture needle. Use a sealing snap ring to ensure no leakage.

[0085] Test of the electromagnetic sealing adapter 601:

[0086] Send instructions to control the on / off of the two-way solenoid valve, and verify that the start / stop response time of the dialysis fluid flow ≤ 0.2 s.

[0087] Simulate pipeline pulling, check the bending buffer effect of the spring steel protective pipe sleeve 606, and ensure that the pipeline bending angle ≤ 15°.

[0088] System linkage debugging and dynamic response

[0089] Position sensor 7 calibration: Calibrate the initial position through the gyroscope 1071 and the accelerometer 1072, and set the displacement threshold (horizontal displacement > 5 cm or rotation > 10° triggers a response).

[0090] Dynamic follow-up test:

[0091] Patient simulated turning over: The position sensor 7 detects the displacement signal, the central controller 2 synchronously controls the movement of the electric telescopic suspension bracket 3, and the reel 402 releases or retracts the pipeline according to the data of the tensile force sensor 408.

[0092] Pipeline status monitoring: Verify that there is no bending throughout the pipeline, and the tensile force is always maintained at 2 - 5 N.

[0093] Puncture point protection verification: Apply a 10 N lateral tensile force to the dialysis tube, and check that the displacement of the puncture needle nozzle 603 ≤ 0.5 mm.

[0094] Abnormal handling and maintenance

[0095] Pipeline overload protection: When the tensile force sensor 408 detects a tensile force > 15 N, the reel 402 immediately releases the pipeline and triggers an audible and visual alarm, and at the same time the central controller 2 records the fault code.

[0096] Abnormal handling of puncture point pressure: When the pressure of the inflatable fixing sleeve 503 exceeds the limit, automatically adjust the inflation amount or prompt the medical staff to intervene manually.

[0097] System self-check: After powering on every day, execute the automatic calibration process, including sensor zero calibration, retest of the telescopic arm stroke, and solenoid valve response test.

[0098] Technical effects of the device

[0099] Dynamic follow-up control

[0100] The electromagnetic adsorption fixing seat 1 and the electric telescopic suspension bracket 3 are servo-driven through the nested telescopic arm 301, and cooperate with the real-time displacement monitoring of the position sensor 7 to achieve millimeter-level synchronous follow-up of the dialysis pipeline and the patient's movements. The central controller 2 dynamically adjusts the length and horizontal offset of the telescopic arm according to the position data to ensure that the pipeline remains in a slightly stretched state throughout the process (tensile force control accuracy ±0.5 N), effectively avoiding pipeline bending or excessive pulling caused by the patient turning over, and reducing the risks of pipeline blockage and blood coagulation.

[0101] Zero displacement protection of the puncture point

[0102] The anti-pulling dialysis tube coupler 6 rigidly connects to the puncture point protective arm sleeve 5 through the electromagnetic sealing adapter 601, completely isolating the tube pulling force outside the puncture needle nozzle 603. The puncture needle nozzle 603 moves synchronously with the puncture point protective arm sleeve 5 and remains relatively stationary with respect to the patient's limb. The displacement of the puncture needle is ≤ 0.5 mm, significantly reducing the risks of blood vessel injury, hematoma, and infection.

[0103] Adaptive pipeline management

[0104] The stretching force sensor 408 of the dialysis tube follower retractor 4 real-time detects the pipeline pulling force and dynamically controls the release or recovery speed of the roller 406 (response time ≤ 0.3 s). The pipeline electric clamp 404 and the guide roller 409 work together to ensure that the pipeline bending radius ≥ 8 cm, avoiding bending and blockage. This mechanism extends the service life of the pipeline and reduces the frequency of manual intervention in clinical operations.

[0105] System stability and reliability

[0106] The magnetic force intensity adaptive adjustment function of the electromagnetic adsorption fixing seat 1 can resist the vibration generated by the patient's movement (amplitude ≤

[0107] 0.2 mm). The power supply module 103 adopts a redundant design to ensure that the magnetic force is maintained for ≥ 10 s during power failure, providing a buffer time for emergency handling. The pressure sensor 507 of the inflatable fixing sleeve 503 real-time feedbacks data and automatically adjusts the air pressure to adapt to limb movements, avoiding puncture needle displacement.

[0108] Intelligent operation and maintenance

[0109] The central controller 2 is built-in with a self-checking algorithm, which automatically performs sensor calibration, telescopic arm stroke verification, and pipeline status detection after power-on every day. Abnormal situations (such as excessive pulling force, abnormal air pressure) trigger audible and visual alarms, and push fault codes to the medical staff terminal through the wireless module, supporting remote diagnosis and maintenance, and improving the equipment management efficiency.

[0110] Personalized adaptation and safety improvement

[0111] The inflatable fixing sleeve 503 of the puncture point protective arm sleeve 5 can be inflated adaptively according to the patient's arm size (pressure range 0.1 - 0.3 kPa). Combined with the buffer design of the spring steel protective tube sleeve 606, it adapts to the clinical needs of patients with different body types. The LED supplementary light of the anti-atomization puncture needle observation window 506 provides shadowless lighting, ensuring that medical staff can clearly observe the puncture point status and reducing operation errors.

[0112] Multiple redundant protection mechanisms

[0113] Pipeline protection: The double anti-bending design of the spring steel protective tube sleeve 606 and the guide roller 409 reduces the pipeline bending rate by 90%.

[0114] Puncture point protection: The pressure sensor 507 is linked with the electromagnetic sealing adapter 601 to automatically cut off the flow of dialysis fluid when the pressure exceeds the limit, preventing leakage.

[0115] System protection: The anti-slip silica gel layer 102 and the redundant power module 103 of the electromagnetic adsorption fixing seat 1 ensure the stability of the device under extreme conditions.

[0116] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
