Bladder hyperthermic perfusion device and dustproof lifting mechanism thereof

Abstract

The invention relates to a bladder hyperthermic perfusion device and a dustproof lifting mechanism thereof. The dustproof lifting mechanism comprises a lifting assembly, a dustproof assembly and a lifting platform; the lifting assembly comprises a driving source, a driving shaft and a lifting block, the dustproof assembly comprises a lifting base, a dustproof belt, an upper rolling shaft and a lower rolling shaft, the driving shaft can be driven by the driving source to move, and the lifting block rises or falls in the lifting direction to drive the lifting platform to rise or fall, so that aheating can carried on the lifting platform rises or falls. Since the lifting platform is fixed on a mounting part of a mounting base, the mounting part is exposed out of a shell through a sliding groove in the shell; since the other end of the dustproof belt bypasses the upper rolling shaft, penetrates through the lifting base, bypasses the lower rolling shaft and then is fixed on the lifting base, the dustproof belt can always abut against the inner side wall of the shell, and in the rising or falling process, the dustproof belt can always cover the sliding groove to effectively prevent debris or dust from entering the shell.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bladder heat perfusion device and a dust-proof lifting mechanism thereof. Background technique [0002] Bladder cancer is one of the most common tumors in the urinary system. Bladder cancer is divided into: non-muscle-invasive bladder cancer and muscle-invasive bladder cancer. Among them, non-muscle-invasive bladder cancer is characterized by high recurrence and low progression. The treatment of non-muscle-invasive bladder cancer is surgical treatment: mainly transurethral resection of bladder tumor (TURBT). Non-muscle invasive bladder cancer has a high recurrence rate after surgery, 20%-70% of patients relapse within one year after TURBT, and the use of bladder circulation heat perfusion device for treatment after TURBT is a very important means of preventing recurrence . Bladder circulation heat perfusion device combines hyperthermia and chemotherapy comprehensivel...

Problems solved by technology

However, other parts of the lifting mechanism except the lifting platform are hidden inside the casing. In order to make the lifting platform outside the casing, a chute must be opened on the side wall of the casing.

However, opening a chute on the casing may cause sundries or dust to enter the inside of the casing through the chute.
