Description

An abdominal diagnostic instrument for measuring abdominal force and its application method

technical field

The invention belongs to the field of medical lateral inspection methods and lateral inspection equipment, and in particular relates to a detection method for measuring abdominal force and an abdominal diagnosis instrument thereof.

Background technique

"If there are all inside, there must be all outside" is one of the basic theories of TCM syndrome differentiation and treatment. Abdominal diagnosis in traditional Chinese medicine is a method for doctors to understand and infer the patient's physical state, viscera, qi and blood lesions, and pathogenic aggregation by observing the "outside" of the patient's abdomen during clinical diagnosis. In order to make the abdominal diagnosis quantitative and objective, from the late 1980s to the 1990s, several abdominal diagnosis measuring devices related to "abdominal tension" were successively developed in China. For example, the authorized announcement number is CN246148Y, an abdominal force detection device designed by Sun Hanjun and He Xinhui. Its measurement method is to preset the displacement of the subsidence of the probe, and the displacement of the subsidence of the probe reaches the displacement of the subsidence. The collected pressure data is valid and processed to obtain the abdominal tension value. , and divided into five grades of "soft", "soft", "medium", "solid", and "solid", which are displayed on the display screen and can be printed by the printer. However, there are many shortcomings in this kind of measurement method, mainly in the following aspects:

(1) Controlling the operation speed of the measuring probe is not considered, because the operation speed of the probe is too fast or too slow, which will cause measurement errors. The condition for judging whether the collected pressure data is valid by this method is only whether the probe reaches the displacement of the sunken abdomen, which affects Measurement accuracy and reliability.

(2) Abdominal temperature measurement was not considered, because according to the cold and heat syndrome differentiation theory of traditional Chinese medicine, only the abdominal diagnosis with simultaneous abdominal temperature measurement can fully and truly reflect the physiological and pathological status of the patient.

(3) Printing the time-pressure relationship measurement process trend chart was not considered, because only printing the abdominal tension value at a certain time point could not reflect the degree of interference in the measurement process, so the accuracy and reliability of the measurement could not be ensured.

Contents of the invention

The object of the present invention is to avoid the above disadvantages, to provide an abdominal diagnostic instrument for measuring abdominal force and its use method. The sliding plate can only be effective if the pressure and temperature data collected by the sensor meet the displacement and time conditions at the same time, so as to control the operation of the measuring probe. Speed; measure abdominal pressure and abdominal temperature at the same time, providing an objective basis for the theory of cold and heat syndrome differentiation in traditional Chinese medicine: by printing the trend chart of the time-pressure relationship measurement process, judge the degree of interference in the measurement process.
