Embodiment 1
[0031] Embodiment 1: see attached figure 1 And attached figure 2As shown, a postoperative drainage device for breast cancer includes a negative pressure chamber 1 and a partition 8 arranged in the negative pressure chamber 1; the partition 8 divides the negative pressure chamber 1 into an equipment chamber and a negative pressure chamber ; The negative pressure chamber is provided with a piston 6, the contact surface of the piston 6 and the inner side wall of the negative pressure chamber is covered with a sealing ring, and the negative pressure chamber is divided into a front chamber 5 and a rear chamber by the piston 6 7. The front chamber 5 is connected to the fluid chamber 2 through a pipeline, and the fluid chamber 2 is connected to the drainage tube 3; the piston 6 is connected to the piston rod 9, and the piston rod 9 passes through the rear chamber 7 It penetrates through the partition plate 8 and extends into the equipment chamber, and the equipment chamber is provi...
Embodiment 2
[0044] Embodiment 2: The difference with the above-mentioned embodiment 1 is that the driving device of the present embodiment 2 adopts an electric push rod, and the telescopic end of the electric push rod is connected with the piston rod 9; the electric push rod drives the piston rod 9 to move back and forth, Then drive the piston 6 to move back and forth. However, in terms of Embodiment 1 and Embodiment 2, Embodiment 1 is preferred in the present invention because the control precision of Embodiment 1 is higher than that of Embodiment 2.
[0045] In the present invention, the touch display screen with control function is connected with the motor 10, and the detection information of the pressure sensor and the liquid level sensor is obtained through the display screen to control the speed of the motor 10 or to control the start and stop of the motor 10; The screen reports to the police, and reminds relevant personnel to close motor 10. However, touch display screens with con...
