Negative-pressure inspiratory pressure measuring device and inspiratory pressure measuring method thereof

Abstract

The invention relates to a negative-pressure inspiratory pressure measuring device and an inspiratory pressure measuring method thereof. The negative-pressure inspiratory pressure measuring device comprises a gas pipe, a spring and an indication piece, wherein the gas pipe contains a scale unit representing the air pressure; the inside of the gas pipe is provided with a gas channel, a first opening and a second opening; the first opening is used to connect the gas channel with the outside and connected with the patient; the second opening is used to connect the gas channel with the outside and opposite to the first opening; the spring contains a fixing end used for connecting the gas pipe and a free end which is opposite to the fixing end and close to the second opening; and the indication piece is arranged on the free end and can move in the gas channel. When the patient inhales, gas flows in the gas channel from the second opening and flows out through the first opening, the indication piece is driven by gas to move to the first opening and compress the spring; and the indication piece corresponds to the position of one measurement pressure value of the scale unit. The pressure measuring device of the invention has simple structure and small volume, can reduce the manufacturing hours and the manufacturing cost, and can also measure the gas pressure quickly and accurately when the patient inhales.

Description

technical field [0001] The present invention relates to a negative pressure inspiratory pressure measurement device and its inspiratory pressure measurement method used in respiratory medical care, in particular to a method for judging whether the patient can breathe by measuring the gas pressure value when the patient inhales. A negative pressure inspiratory pressure measurement device and a method for measuring the inspiratory pressure used without the respiratory system. Background technique [0002] In order to know whether the patient who relies on the respiratory system to maintain the breathing operation has the ability to breathe spontaneously, a gas pressure measuring device is usually installed on the respiratory system to measure the gas pressure of the patient when inhaling, by means of the measured gas The pressure value is used to judge the ability of the patient to breathe spontaneously, so that the caregiver can decide whether the patient can be separated fro...

Problems solved by technology

[0003] Since the structure and design of the pressure measurement device in this case is relatively complicated, and the overall volume is large, it not only consumes more manufacturing man-hours in manufacture, but also has a higher manufacturing cost. It can be seen that the above-mentioned existing gas pressure measurement Obviously, there are still inconveniences and defects in the product structure and use of the testing device, and further improvement is urgently needed

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
