Problems solved by technology
This patent application technology solves the problems of liquid medicine heating and liquid injection to a certain extent, but there are some shortcomings and deficiencies: the heater and the temperature measurement sensor are sealed with a plastic sleeve, so the heating efficiency is low and the temperature measurement is ineffective. deviation
The interface between the temperature measuring sensor and the heater and the urinary catheter is sealed with epoxy resin, so the strength is insufficient and the softness is not enough; it adopts a bag to fix the urinary catheter, and the heater at the front end of the catheter will be in contact with the bladder wall. Candling tissue on the surface of the bladder wall

The four cavity tube for intracavitary thermotherapy and chemotherapy of urinary bladder cancer includes heating RF antenna, temperature sensor, locating air bag, four cavity urinary catheter of silicon rubber, wire, plug and protecting air bag. The heating RF antenna, the temperature sensor, the locating air bag and the protecting air bag are set on to the outer surface of the four cavity urinary catheter; and the wire has one end connected to the plug and the other end connected to the heating RF antenna and the temperature sensor via the four cavity urinary catheter. By means of the heating RF antenna and the temperature sensor, the temperature is stabilized at some temperature point in 42-44 deg.c to reach the therapeutic effect.
Description
technical field [0001] The invention relates to a four-chamber treatment tube for intracavity hyperthermia and chemotherapy of bladder cancer, which is a device for heating hyperthermia and chemotherapeutic liquid in the bladder cavity. Used in the field of medical devices. Background technique [0002] The four-chamber treatment tube is the key device of the bladder radiofrequency endocavity thermochemotherapy treatment equipment, which is very important for injecting thermochemotherapy liquid into the bladder cavity and discharging treatment waste liquid, urine process, radio frequency heating efficiency and temperature control process. Intracavitary thermal chemotherapy for bladder cancer requires a heater with fast temperature rise and high temperature control accuracy; at the same time, radio frequency heating can make the thermal effect penetrate deep into the tissue. [0003] After searching the prior art, it is found that: Chinese patent announcement number CN238133...
