Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0021] As Figure 1 , Figure 2 , Figure 3 and Figure 4 indicated, the utility model provides a technical scheme: a surgical operation with drainage catheter measuring equipment, including drainage tube body 1, negative pressure suction ball body 2, drainage liquid measurer body 3 and drainage bag body 4, the bottom end of drainage tube body 1 is fixedly connected with the top end of negative pressure suction ball body 2, and the bottom end of negative pressure suction ball body 2 is fixedly connected with the top end of drainage liquid measurer body 3, and the first connecting pipe 5 is fixedly connected between the bottom end of drainage liquid measurer body 3 and the top end of drainage bag body 4, the bottom end of drainage bag body 4 is fixedly connected with the drainage pipe 7, and the outer wall of negative pressure suction ball body 2 is fixedly connected with pressure control valve 8.
[0022] According to the overall structure of the device, the pressure in the negative pressure suction ball body 2 is adjusted by the pressure control valve 8, so that the negative pressure suction ball body 2 is used to maintain negative pressure, the drainage liquid enters the drainage liquid measurer body 3 through the first connecting pipe 5, and the drainage volume is measured by the drainage liquid measurer body 3, the drainage liquid measurer body 3 is a transparent hose, so that the measured drainage liquid is squeezed into the drainage bag body 4 through the second connecting pipe 6, is stored or is discharged through the drainage pipe 7, the drainage volume can be accurately recorded at any time per shift, the patient's condition change is closely observed, the infection opportunity is reduced, and the workload of the staff is also reduced.
