Description

Technical Field

[0001] The utility model relates to a bracket for an adjustable negative pressure drainage ball liquid measuring device for a radiotherapy department, in particular to a bracket for an adjustable negative pressure drainage ball liquid measuring device for a radiotherapy department, and belongs to the technical field related to medical devices. Background Art

[0002] In the existing medical negative pressure drainage ball liquid measuring device, for example, the technical structure of the application document with application number CN201921216408.7 includes a bracket, a piston measuring cylinder, a drainage ball, a hydraulic cylinder and a control device. The lower end of the bracket is provided with a base for placing the piston measuring cylinder. The bracket is provided with a first clamping ring for fixing the drainage ball and a second clamping ring for fixing the hydraulic cylinder from bottom to top. The upper end of the bracket is provided with two limit switches for limiting the stroke of the hydraulic cylinder. The piston measuring cylinder is marked with a first scale for measuring the volume of the liquid. The lower end of the piston rod is provided with a parabolic rotating body pressure head for squeezing the drainage ball, and the upper end of the piston rod is provided with a touch rod for contacting the limit switch. Although the device squeezes the drainage ball through the pressure head to discharge the accumulated liquid inside the drainage ball, due to the limitation of the silicone rubber material of the drainage ball itself, the upper half of the sphere and the lower half of the sphere will not overlap well to discharge the liquid during the extrusion of the pressing block, and the structure is too complicated, requiring a controller, and the volume is large, which is very inconvenient to operate.

[0003] The existing patent is a medical negative pressure drainage ball liquid measuring device, the patent authorization number is CN 219049729U. The device realizes that when the accumulated liquid in the drainage ball is discharged, the upper hemispherical plastic film and the lower hemispherical shell are tightly fitted, so as to better drain the accumulated liquid in the drainage ball and reduce the residual liquid in the drainage ball, which greatly reduces the influence of the shape of the drainage ball itself and improves the reading accuracy of the measuring tube for the liquid.

[0004] However, in the patent authorization number CN 219049729 U, the medical negative pressure drainage ball liquid measuring device is mainly operated and measured by hand in the process of operation by different staff members, which is inconvenient to observe and measure the drainage fluid inside the measuring tube. To solve the above problem, we propose an adjustable negative pressure drainage ball liquid measuring device bracket for radiotherapy department. Utility Model Content
