[0030] The present utility model provides a drainage control device, particularly an electronic control device for venous drainage, without limiting its application scenarios.
[0031] Referring to Figures 1 to 3 , in an embodiment of the present utility model, the drainage control device includes a fixing mechanism 10, a clamping mechanism 20, and a controller; the fixing mechanism 10 is adapted to be fixed on a medical trolley; the clamping mechanism 20 includes a driving member and a clamping member 21. The two clamping arms of the clamping member 21 are arranged opposite to each other and form a clamping space 20a for clamping a drainage tube. The driving member is drivingly connected to the clamping member 21 and is used to drive the two clamping arms of the clamping member 21 to move relatively away from or close to each other to change the size of the clamping space 20a; the controller is electrically connected to the driving member, and the controller is used to control the operation of the driving member.

[0034] The controller can adopt a microprocessor such as a single-chip microcomputer, a DSP, and an FPGA, etc., which is not limited herein.
[0035] It can be understood that the present utility model provides a drainage control device. By controlling a driving member such as a motor to rotate forward or backward through a controller, the relative distance between the two clamping arms is adjusted, thereby changing the size of the clamping space 20a, and further controlling the flow rate of the liquid flowing through the drainage tube, accurately controlling the venous drainage, improving the accuracy of controlling the percentage of the total venous trunk, and enhancing the convenience of operation, saving time and effort.

The two clamping arms are respectively movably sleeved on the guiding column 23 and slidably arranged on the sliding rail 24, and at least one of the clamping arms is drivingly connected to the driving member. In this way, the adjustment of the distance between the two clamping arms is realized, that is, the adjustment of the size of the clamping space 20a is realized, and the flow rate of the drainage tube can be controlled by controlling the relative distance between the two clamping arms, further improving the accuracy of controlling the percentage of the total venous trunk.

Among them, the battery may be a rechargeable battery.
[0042] The present utility model designs a drainage control device. The clamping mechanism 20 is driven by a motor connected to a rechargeable battery. By rotating the adjustment knob 12, the percentage of the total venous trunk can be accurately controlled, making the management of the anterior parallel and posterior parallel more precise and accurate. This is particularly important for critically ill patients, as well as for pediatric patients, especially newborns.

The knob 12 is connected to one end of the locking rod 13, and the other end of the locking rod 13 is movably inserted into the clamping groove and is used to press the support rod or fixing plate of the medical trolley against the clamping groove.
[0044] To further improve the convenience of operation and the applicability of the drainage control device, referring to 1 and Figure 2 , in one embodiment, the drainage control device may further include a connecting mechanism 40 that connects the fixing mechanism 10 and the clamping mechanism 20.
[0045] In this embodiment, the connecting mechanism 40 includes a first connecting rod 41, a second connecting rod 42, and a locking member 43. The first connecting rod 41 and the second connecting rod 42 are rotatably connected by a rotating shaft. The locking member 43 is disposed at the connection of the first connecting rod 41 and the second connecting rod 42 and is used to lock or loosen the first connecting rod 41 and the second connecting rod 42. The first connecting rod 41 and the fixing mechanism 10, and the second connecting rod 42 and the bottom plate 22 are both rotatably connected by a connecting ball head 44. Thus, by adopting the above structure, the clamping mechanism 20 can be manually adjusted in multiple directions relative to the fixing mechanism 10 to be in a suitable position for drainage, greatly improving the convenience of the drainage operation.
