Multi-point pressure testing tube and use method thereof

Abstract

The invention discloses a multi-point pressure testing tube and a use method thereof, relates to the field of medical apparatus and instrument detection equipment, and particularly designs a multi-point pressure testing tube used inside bladders and urethras, and a use method of the multi-point pressure testing tube. The multi-point pressure testing tube comprises a detection catheter, a plurality of detection connectors and a data channel, wherein the detection catheter is a soft catheter; the front end of the detection catheter is of a sealed structure; the plurality of the detection connectors are arranged inside the detection catheter; the detection connectors are uniformly arranged on the front end of the inner side of the detection catheter and the side wall of the detection catheter; the detection connectors are arranged in different positions inside the detection catheter; the detection connectors are connected with the data channel through a data lead; the lower end of the data channel is connected with a computer terminal. The multi-point pressure testing tube has the beneficial effects that multi-point detection can be achieved simultaneously, multiple testing points are tested by doctors, then data as accurate as possible can be obtained, the multi-point pressure testing tube is accurate in testing result, good in repeatability, reliable to fix and easy to operate, and patients can be greatly relieved from pain.

Description

technical field [0001] The invention relates to the field of medical device testing equipment, and specifically designs a multi-point pressure measuring tube in the bladder and urethra and a use method thereof. Background technique [0002] The existing measurement of bladder and urethral pressure mostly adopts a double-lumen catheter, externally connected to a pressure transducer, and the pressure transducer converts the pressure signal into a digital signal and inputs it to a computer for data processing. This measurement method has the following disadvantages: 1. The pressure in the bladder and urethra is transmitted to the pressure transducer through a long catheter. The liquid travels a long path, often exceeding 1 meter. The pressure measurement is greatly affected by external factors. Insufficient connection of the pressure measuring tube, the height of the connection position, air bubbles in the pressure measuring tube and the connecting tube, or inaccurate balance w...

[0002] The existing measurement of bladder and urethral pressure mostly adopts a double-lumen catheter, externally connected to a pressure transducer, and the pressure transducer converts the pressure signal into a digital signal and inputs it to a computer for data processing. This measurement method has the following disadvantages: 1. The pressure in the bladder and urethra is transmitted to the pressure transducer through a long catheter. The liquid travels a long path, often exceeding 1 meter. The pressure measurement is greatly affected by external factors.

Insufficient connection of the pressure measuring tube, the height of the connection position, air bubbles in the pressure measuring tube and the connecting tube, or inaccurate balance will obviously affect the pressure measurement results

2. When measuring the static urethral pressure, it is measured while perfusing. The pressure measuring hole is the measuring hole. The speed of perfusion and pulling rod, and the position of the pressure measuring hole (the results of the pressure measuring hole upward, downward or to both sides may vary) Obviously affect the measurement results, and it is very difficult to control the position of the pressure measurement hole

3. It is not easy to fix, and it is easy to fall out during the pressure-flow rate measurement, which will affect the pressure measurement results

4. The current pressure measuring tube is for one-time use and consumes a lot

5. Poor repeatability when using the current pressure measuring tube for pressure measurement

[0003] Chinese patent 201320414860.0 utility model patent records a balloon pressure measuring tube, the structure is equipped with multiple independent mechanism channels, the structure is relatively complicated and the test data is still not accurate enough
