Description

[0002] During hemodialysis, the length, bends and tension management of the dialysis tube directly affect the efficiency of the operation and the comfort of the patient. However, most of the existing dialysis tube winding equipment relies on manual operation, which is inefficient and prone to human error.

[0003] For example, a catheter fixing and recovery device for hemodialysis disclosed in Chinese patent CN214031271U includes a bottom plate, a first vertical plate fixedly connected to the top surface of the bottom plate, a second vertical plate fixedly connected to the top surface of the bottom plate, the first vertical plate and the second vertical plate are symmetrically distributed, a diagonal rod fixedly connected to one side of the second vertical plate, a motor detachably connected to one end of the diagonal rod, two diagonal rods, the motor output end is connected to the shaft input end, a hole is opened inside the second vertical plate, the motor drives the shaft input end connected to its output end to rotate, so that the shaft rotates in the hole opened on the surface of the second vertical plate, and is supported by a circular bearing embedded in the inner wall of the hole, that is, one end of the shaft is against one side of the first vertical plate without affecting the rotation, and a space for recovering the catheter is formed by the first vertical plate and the second vertical plate. This device can attach the catheter through multiple circular grooves opened on the surface of the shaft, but there is no structure to limit the wire, and the catheter is easy to slip out of the circular groove when the shaft rotates.

[0004] In addition, the prior art also has the following shortcomings: 1. Traditional dialysis tube recycling methods mainly rely on manual operations, which are time-consuming and inconvenient. Especially in high-intensity working environments, such as a large number of dialysis operations in the hematology department, manual recycling can easily lead to fatigue or irregular operations. 2. Hemodialysis has extremely high requirements for the sanitary environment, but most pipe recycling devices fail to integrate effective disinfection functions. Contaminants or pathogens may remain on the surface of the recycled pipes, increasing the risk of cross-infection, especially in multi-patient treatment environments. 3.

The following embodiments will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.

[0035] Embodiment 1: According to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, this embodiment provides a hemodialysis tube winding and recovery system with adjustable tension, the hemodialysis tube winding and recovery system comprises a connecting seat 1, a tension adjustment module, a pipeline recovery module, a hygiene management module and a user interaction module, the tension adjustment module, the pipeline recovery module and the user interaction module are arranged on one side end surface of the connecting seat 1, and the other side end surface of the connecting seat 1 is detachably connected to the outer wall of the dialyzer; The tension adjustment module adjusts the tension of the dialysis tube 4, the pipeline recovery module winds and recovers the dialysis tube 4, the hygiene management module disinfects the wound and recovered dialysis tube 4, and the user interaction module allows the user to interact; Among them, the hygiene management module is arranged on the winding path of the dialysis tube 4, such as Figure 5 and Figure 6 shown.

[0036] The hemodialysis tube 4 winding and recovery system also includes a central processing unit, which is respectively controlled and connected to the tension adjustment module, the pipeline recovery module, the hygiene management module and the user interaction module, and centrally controls the tension adjustment module, the pipeline recovery module, the hygiene management module and the user interaction module based on the central processing, thereby improving the efficiency and reliability of the entire system for winding and recovering the dialysis tube 4.

[0037] The tension adjustment module includes a tension detection unit and an intelligent adjustment unit. The tension detection unit detects the tension state data of the dialysis tube 4 in real time. The intelligent adjustment unit evaluates the dialysis tube 4 according to the tension state data and the setting data of the user interaction module to form an evaluation result, and triggers the control of the pipeline recovery module. The tension detection unit is arranged on the recovery and movement path of the dialysis tube 4 .

[0038] Optionally, the tension detection unit includes a force sensor and a photoelectric sensor 7, wherein the photoelectric sensor 7 monitors the position and movement speed of the dialysis tube 4 on the recovery path, and the force sensor is arranged on the roller and the loading member, and directly measures the tension exerted on the dialysis tube 4 during winding or movement.

[0039] Optionally, the intelligent adjustment unit obtains the tension state data and the setting data of the user interaction module, and calculates the winding index Twine according to the following formula: ; In the formula, T is the real-time tension, S is the user-set value, T targetis the reference tension under ideal conditions, v is the movement speed of the dialysis tube, positive and negative represent the tendency of pushing in and pulling out respectively, v max The maximum speed allowed for the movement of the dialysis tubing; If the winding index Twine does not fall within the set monitoring range [range1, range2], the intelligent adjustment unit is triggered to control the pipeline recovery module; In this embodiment, the control includes adjusting the winding direction, the winding speed and the winding amount; If the twine index Twine falls within the set monitoring range [range1, range2], the current state of the dialysis tube meets the system requirements; In this embodiment, after each triggering, the recovery or winding operation is performed only once, and then stops until the next triggering.

[0040] In this embodiment, the winding amount is controlled in each operation to prevent over-winding.

[0041] The intelligent adjustment unit determines the winding amount W according to the following formula: ; In the formula, v recall (t) is the recovery speed at the tth moment, t is the winding time, and its value is set by the system; In the above formula, the upper limit of the integral t is fixed, that is, each time the operation is triggered, the system sets a fixed time period t and completes the recovery or winding operation within this time. At the same time, the difference in the winding amount W comes from the speed v recall (t) is a dynamic adjustment rather than a change in the upper limit of the integral.

[0042] Specifically, each trigger only performs one operation, within the set fixed time period t, according to the real-time speed v recall (t) Calculate the winding amount to avoid overwinding.

[0043] At the same time, each time the recycling operation is performed, the winding amount W increases according to the recycling speed and recycling time, and when W reaches the maximum winding amount W max , stop recycling or winding, and avoid over-winding; The intelligent adjustment unit dynamically adjusts the recovery speed according to the change of the current winding index to ensure that the recovery speed is appropriate each time: The intelligent adjustment unit calculates the recovery speed v at time t according to the following formula: 1recall (t): ; In the formula, v base is the basic recovery rate, k twineis an adjustment coefficient used to adjust the degree of speed adjustment. Increase the adjustment coefficient when it is necessary to accelerate the recovery speed, and decrease the adjustment coefficient when it is necessary to slow down the recovery speed.

[0044] Among them, if Twine < range1, it indicates that the tension is too low, which may cause the dialysis tube to loosen. At this time, a forward rotation recovery (clockwise direction) is triggered to push the dialysis tube into the recovery cavity. Then, the intelligent adjustment unit controls the pipeline recovery module to perform an operation of accelerating the recovery speed in the forward rotation; If Twine > range2, it indicates that the tension is too high, which may cause the dialysis tube to be overly wound or overstressed. At this time, a reverse rotation recovery (counterclockwise direction) is triggered to let the dialysis tube loosen and return to the normal state. Then, the intelligent adjustment unit controls the pipeline recovery module to perform an operation of slowing down the recovery speed in the reverse rotation; In this embodiment, the complete control process is as follows: 1) Real-time monitor the winding index Twine: The system continuously calculates and monitors the value of the winding index Twine to determine whether it exceeds the set monitoring range [range1, range2].

[0045] 2) Trigger the recovery or winding operation: If the winding index Twine exceeds the monitoring range, trigger a recovery or winding operation once.

[0046] After each trigger, the system performs a single recovery operation, including: adjusting the recovery direction, adjusting the recovery speed, and controlling the recovery amount (to prevent overwinding).

[0047] 3) Execute the operation and stop: After the operation is completed, the recovery system stops until the next trigger.

[0048] The system decides whether to continue the recovery or winding according to the feedback of the winding index until the winding index returns to the normal range.

[0049] Optionally, the pipeline recovery module includes a flexible fixing unit, a dynamic winding unit, and a roller loading unit. The roller loading unit is arranged on the path of the dialysis tube 4 and supports the dialysis tube 4. The flexible fixing unit is detachably clamped on the dialysis tube 4. The dynamic winding unit dynamically drives the flexible fixing unit to rotate according to the evaluation result of the intelligent adjustment unit, and linearly recovers and releases the dialysis tube 4; Among them, the flexible fixing unit includes a fixing frame 12, a lock, and a limit seat 16.

[0050] Optional, such as Figure 8 As shown, the limiting seat 16 is provided with an arc limiting portion, and the middle section of the dialysis tube 4 is nested on the arc limiting portion.

[0051] The arc limiting portion is provided with an arc adapted to the dialysis tube 4 , so that during the winding and recovery process of the dialysis tube 4 , the dialysis tube 4 will not be folded or twisted, causing the dialysis process to be interrupted or not smooth.

[0052] Optionally, the dynamic winding unit includes a winding chamber, a winding drive mechanism 17, a drive seat 31, a driving gear 30, a transparent protective cover 2, and a connecting rod 29.

[0056] In this embodiment, the dynamic winding unit further comprises a buffering member, and the buffering member is used to buffer and lift the dialysis tube 4 to form a buffering dialysis tube 4 area; The buffer member is arranged at the winding opening of the dialysis tube 4, and performs buffering on the dialysis tube 4 entering the winding cavity; The buffer setting includes retaining the dialysis tube 4 entering the winding chamber to form an annular buffer area to prevent excessive winding or release, which may cause inappropriate tension; The buffer component includes a buffer airbag 5, a buffer air pump, a buffer seat, and an electronic release valve.

[0057] In this embodiment, the electronic deflation valve is set to retain part of the gas during the deflation process so that the airbag can maintain a certain expansion state, thereby maintaining the annular cushioning posture.

[0058] When the device recycles a certain amount of pipes, the redundancy generated by the buffer can, to a certain extent, prevent the patient from turning over or making large movements during dialysis.

The suction guide piece is arranged inside the suction cup to guide the magnetic force to concentrate on the bottom of the suction cup to improve the magnetic adsorption efficiency.

[0088] The embedded magnet is embedded in the main material of the suction cup, which usually means that the magnet is completely covered or fixed by the main material of the suction cup (such as rubber or silicone), and the suction guide is inside the functional area of ​​the suction cup (usually the inner cavity), that is, the embedded magnet is usually inside the suction cup body, a certain distance away from the suction surface, and the suction guide is close to the bottom of the suction cup, and is in closer contact with the suction surface. The stable connection function of the connection module and the dynamic recovery function of the pipeline recovery module make the pipeline recovery process smoother, avoid winding errors caused by equipment shaking or improper position, and ensure that the entire system has the stability and accuracy of the recovery process.

T(t) is the surface temperature collected in real time at the tth moment, which is collected by the temperature sensor.

If the sensor accuracy is high, k=0.2; if the environmental noise is large or the sensor nonlinearity is serious, k=0.4. When the temperature control index Control does not fall into the monitoring threshold range [sui1, sui2] set by the system, the drying unit is triggered to perform a drying operation on the dialysis tube; When the temperature control index Control falls into the monitoring threshold range [sui1, sui2] set by the system, it means that the current state of the dialysis tube meets the requirements of the system and there is no need to perform a drying operation; Among them, the monitoring threshold range [sui1, sui2] set by the system is set by the system or the administrator according to the actual situation. This is a technical means well known to technicians in this field. Technicians in this field can refer to relevant technical manuals to learn about the technology, so it will not be repeated one by one in this embodiment.

[0092] The temperature control analysis unit obtains the temperature control index Control and the monitoring threshold range [sui1, sui2] set by the system, and calculates the heat value hot according to the following formula: ; Where Control is the temperature control index, sui2 is the lower limit of the monitoring threshold range, sui1 is the upper limit of the monitoring threshold range, κ is the heating constant, and ϵ is a small positive value to prevent the denominator from being zero (the value is: ϵ=10 -6 ), dimensionless.

[0093] Wherein, the heating constant is calculated according to the following formula: ; Where m is the mass of the air around the dialysis tube (unit: kg), c is the specific heat capacity of the air (unit: J / kg·K), ΔT is the target temperature rise (unit: K), and Δt is the time period (unit: s), which indicates the time required for the system to reach the target temperature rise.

[0094] The mass m of the air around the dialysis tube is calculated according to the following formula: ; Where ρ is the air density, usually 1.2 kg / m 3 At standard atmospheric pressure and temperature), v is the air intake velocity (unit: m / s), A is the cross-sectional area of ​​the drying channel (unit: m 2 ), t is the air flow time (unit: s), and its value is set according to the time interval of the drying task and is set by the system.

[0095] The temperature control analysis unit transmits the heat value hot to the central processing unit, so that the central processing unit controls the drying unit to generate heat according to the heat value hot.

[0096] Through real-time data analysis and feedback coordination between the status acquisition unit and the temperature control analysis unit, the drying unit dynamically adjusts the heating and airflow rates to avoid overheating or insufficient drying, thereby ensuring the accuracy and safety of dialysis tube drying.

In the present embodiment, it is arranged on the side of the cleaning unit away from the disinfection unit. The dryer 27 is arranged in the drying channel 11, and blows heated air to the dialysis tube 4, and dries the disinfected dialysis tube 4 to maintain the dryness of the outer wall of the dialysis tube 4. The guide member is arranged in the drying channel 11, and guides the temperature in the drying channel 11 to the dialysis tube 4.

[0099] The guide component includes a guide plate 15, an air outlet 10, an air flow distributor 26, a guide drive mechanism 13 and a connecting rod 29. The air outlet 10 is arranged at one end of the drying channel 11 and connected to the external environment. The air flow distributor 26 is arranged in the drying channel 11 and blows external air to the dryer 27, so that the heated air is blown to the dialysis tube 4. The two ends of the guide plate 15 are hinged to the two side walls of the drying channel 11, one end of the connecting rod 29 is hinged to the guide plate 15, and the other end of the connecting rod 29 is driven and connected to the guide drive mechanism 13 to form a guide portion. The guide portion is arranged on the inner wall of the drying channel 11 and drives the guide plate 15 to reciprocate along the hinge position, thereby realizing the diversion and guidance of the airflow.

[0100] By coordinating the analysis results of the temperature control analysis unit with the dynamic regulation of the drying unit, the drying process can adapt to different humidity conditions, improve drying efficiency, reduce energy consumption, and achieve efficient and energy-saving operation results.

[0101] Through the overall coordination of the cleaning unit, disinfection unit and drying unit, an efficient processing flow is formed, which reduces the time waste of independent operation and ensures the efficiency and economy of system operation.
