Temperature surveys pressure catheter.
Background technique
Existing catheter is mostly used cooperatively with patient monitor, and medical staff understands the temperature of patient's body urine by patient monitor
Degree and pressure.
CN205649494U utility model patent discloses a kind of bladder pressure detection device, is a kind of thermometric survey pressure
Catheter comprising tube body and pressure sensor assembly, temperature sensor assembly, by the way that pipe fitting to be removably attachable to
The pressure detecting end of pipe, and pressure sensor is set to the one end of pipe fitting far from pressure detecting end, so that pressure sensing
Device is arranged far from urinary tract, and one side urine will not be infected with pressure sensor, on the other hand, since pressure sensor is removably
It is connected to pressure detecting end, after directly pulling out pressure sensor, sensor can be reused directly, and then controlled thermometric and surveyed pressure
The cost of manufacture of catheter.
However, the cost of a pressure sensor, which accounts for a set of thermometric, surveys the specific gravity for pressing catheter cost and little, another party
Face, removal sensor and disinfection are also required to cost, it is often more important that sensor reuses meeting once when pollution disinfection is not thorough
The threat of cross-infection is brought to patient.
Further, since pressure sensor is arranged between sensor non-return valve and air bag, when it is infused from injection pipe to air bag
When entering fluid or discharge fluid, fluid all flows through pressure sensor, this will lead to pressure in entire injection or generates in expulsive stage
Dynamic change, peak value or valley are possible to generate false alarm beyond threshold value, be unfavorable for the monitoring of monitor.
Summary of the invention
