Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of the present invention.

The following embodiments will further describe the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention.

[0048] Embodiment One: according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 , the embodiment provides a tension-adjustable hemodialysis tube winding and recycling system, which comprises a connecting seat 1, a tension adjustment module, a tube recycling module, a hygiene management module and a user interaction module, the tension adjustment module, the tube recycling module and the user interaction module are arranged on one side end face of the connecting seat 1, and the other side end face of the connecting seat 1 is detachably connected with the outer wall of a dialysis instrument.

[0049] The tension adjustment module adjusts the tension of the dialysis tube 4, the tube recycling module winds and recycles the dialysis tube 4, the hygiene management module disinfects the wound and recycled dialysis tube 4, and the user interaction module is used for interaction by the user.

[0050] The hygiene management module is arranged on the winding path of the dialysis tube 4, as shown in Figure 5 and Figure 6 .

[0051] The hemodialysis tube 4 winding and recycling system further comprises a central processing unit, which is respectively connected with the tension adjustment module, the tube recycling module, the hygiene management module and the user interaction module, and based on the central processing unit, the tension adjustment module, the tube recycling module, the hygiene management module and the user interaction module are centrally controlled, so as to improve the efficiency and reliability of the whole system for winding and recycling the dialysis tube 4.

[0052] The tension adjustment module comprises 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 tube recycling module.

[0053] The tension detection unit is arranged on the recycling and moving path of the dialysis tube 4.

[0054] Optionally, the tension detection unit comprises a force sensor and a photoelectric sensor 7, the photoelectric sensor 7 monitors the position and moving speed of the dialysis tube 4 on the recycling path, and the force sensor is arranged on the roller and the loading member and directly measures the tension of the dialysis tube 4 in the winding or moving process.

[0055] Optionally, the intelligent adjustment unit acquires tension state data and user interaction module setting data, and calculates the winding index Twine according to the following formula:

[0056]

[0057] In the formula, T is real-time tension, S is user setting value, T target is reference tension under ideal state, v is movement speed of dialysis tube, positive and negative respectively represent push-in and pull-out trend, v max is maximum speed allowed for dialysis tube movement;

[0058] If the winding index Twine does not fall into the set monitoring range [range1, range2], the intelligent adjustment unit triggers control of the pipe recycling module;

[0059] In the embodiment, the control includes adjusting winding direction, winding speed and winding amount;

[0060] If the winding index Twine falls into the set monitoring range [range1, range2], the current state of the dialysis tube meets system requirements;

[0061] In the embodiment, after each triggering, only one recycling or winding operation is performed, and then stopped, until the next triggering, and then the operation is performed again.

[0062] In the embodiment, the winding amount is controlled at each operation to prevent over-winding.

[0063] The intelligent adjustment unit determines the winding amount W according to the following formula:

[0064]

[0065] In the formula, v recall (t) is recycling speed at the t-th moment, t is winding time, and the value is set by the system;

[0066] In the above formula, the upper limit of integration t is fixed, that is, each time the operation is triggered, the system sets a fixed time period t, and completes the recycling or winding operation within the time. At the same time, the difference of the winding amount W comes from the dynamic adjustment of the speed v recall (t), rather than the change of the upper limit of integration.

[0067] Specifically, each time the operation is triggered only once, within the set fixed time period t, the winding amount is calculated according to the real-time speed v recall (t) to avoid over-winding.

[0068] Meanwhile, the winding amount W increases according to the recovery speed and the recovery time each time the recovery operation is performed, and when W reaches the maximum winding amount W max , the recovery or winding is stopped to avoid over-winding;

[0069] The intelligent adjustment unit dynamically adjusts the recovery speed according to the change of the current winding index, ensuring that the recovery speed is appropriate each time:

[0070] The intelligent adjustment unit calculates the recovery speed v 1recall (t) at the tth moment according to the following formula:

[0071]

[0072] where v base is the basic recovery speed, k twine is the adjustment coefficient, used to adjust the degree of speed adjustment, and the adjustment coefficient is increased when the recovery speed needs to be accelerated and is decreased when the recovery speed needs to be slowed down.

[0073] If Twine < range1: indicates that the tension is too low, which may cause the dialysis tube to relax, at this time, the positive rotation recovery (clockwise direction) is triggered to push the dialysis tube into the recovery cavity, and the intelligent adjustment unit controls the pipeline recovery module to perform the operation of accelerating the recovery speed in the positive rotation direction;

[0074] If Twine > range2: indicates that the tension is too high, which may cause the dialysis tube to be over-wound or subjected to excessive force, at this time, the reverse rotation recovery (counterclockwise direction) is triggered to loosen the dialysis tube and restore it to a normal state, and the intelligent adjustment unit controls the pipeline recovery module to perform the operation of slowing down the recovery speed in the reverse rotation direction;

[0075] In this embodiment, the complete control flow is as follows:

[0076] 1) Real-time monitoring of the winding index Twine:

[0077] The system continuously calculates and monitors the value of the winding index Twine to determine whether it exceeds the set monitoring range

[0078] [range1, range2].

[0079] 2) Triggering the recovery or winding operation: if the winding index Twine exceeds the monitoring range, triggering a recovery or winding operation once.

[0080] After each triggering, the system performs a single recovery operation, including adjusting the recovery direction, adjusting the recovery speed, and controlling the recovery amount (to prevent over-winding).

[0081] 3) Execution and stop: after the operation is performed, the recovery system stops until the next triggering.

[0082] The system determines whether to continue to recover or wind according to the feedback of the winding index until the winding index returns to the normal range.

[0093] In the embodiment, the dynamic winding unit further includes a buffering component for buffering and lifting the dialysis tube 4 to form a buffered dialysis tube 4 region.

[0094] The buffering component is arranged at the winding opening of the dialysis tube 4 and buffers the dialysis tube 4 entering the winding cavity.

[0098] In the embodiment, the electronic air release valve is set to release air, and part of the air is reserved to enable the air bag to maintain a certain inflation state, thereby maintaining a ring-shaped buffering posture.
