[0002] Abdominal wall tension refers to the tension of the abdominal muscles when palpating the abdomen. It is the combination of the fullness of the entire abdominal wall and the impedance of the rectus abdominis, the endocutaneous layer of the abdomen, and the impedance of each viscera to display the "visceral-body wall reflex". The tension of the abdominal wall is often affected by the abdominal muscle layer, the impedance of each viscera, and the fullness of the entire abdominal cavity, so it can reflect the physiological and pathological conditions of the body. Measuring the tension of the abdominal wall can understand the systemic and local conditions. For example, abdominal wall tension is one of the important signs of acute peritonitis.

[0032] One end of the elastic component 13 presses against the magnetic head 121, and the other end presses against the detection capacitor plate 14. Specifically, the elastic component 13 is sleeved on the rod body 122, and the elastic component 13 is an elastic rubber sleeve or a spring made of non-magnetic material.

The output module presents the abdominal wall tension information in a display manner such as a digital signal or an analog signal.

[0034] Preferably, the peripheral position of the bottom surface of the probe housing 11 radially increases to form an attaching disc 112, effectively increasing the contact area with the abdominal wall skin and having good placement stability. An adhesive 113, such as self-adhesive, etc., is provided on the bottom surface of the attaching disc 112, which is convenient and simple to use.

[0035] For convenient wiring, a side wire passing hole is provided on the side wall of the probe housing 11 and a central wire passing hole 114 is provided on the top surface of the probe housing 11.

Preferably, the end face of the nail head is a smooth surface, avoiding scratching the skin and improving the use comfort.

[0036] A monitoring method for the above-mentioned abdominal wall tension monitoring system includes the following steps:

[0037] (1) After the power is turned on, the monitoring host 2 starts, the electromagnet 15 is placed in a non-powered state, and the initial value of the frequency setting is assigned as 0;

[0038] (2) Set the frequency value to N, and the abdominal wall tension monitoring system identifies that it is detected once every N minutes. Check whether the detection start button is pressed. If it is pressed, perform the detection according to steps (3)-(6);

[0039] (3) The monitoring host 2 controls the electromagnet 15 to work, and the electromagnet 15 generates electromagnetic suction to adsorb the probe 12 to move downward and press against the abdominal wall skin;

[0040] (4) The monitoring host 2 applies voltage to the probe 12 and the detection capacitor plate 14 and obtains the capacitance value between the two;

[0041] (5) The monitoring host 2 converts and calculates the capacitance value to obtain the distance of the movement of the probe 12, and calculates the abdominal wall tension through the distance of the movement of the probe 12; specifically, in the initial state, the electromagnet 15 does not work; within the elastic range of the elastic component 13, when no electromagnetic switch is involved, the magnetic suction head 121 of the probe 12 is pressed against the top cover in the installation cavity 111. The force balance f s =G 钉头 +f 顶盖 ; f s =k*△d; where f s is the elastic force of the elastic component 13; G 钉头 is the acting gravity of the nail head 123; where f 顶盖 is the force exerted by the top cover on the probe 12; k is the elastic coefficient; △d is the deformation of the elastic component 13.

[0042] Assume that the natural elongation state of the elastic component 13 is d 0 , and the elongation state within a certain elastic range is d n , then the elastic force of the elastic component 13 at any stage can be described as f s =k*(d n -d 0 ); The capacitance calculation formula is C = ε*ε 0 *S*d -1 , in the formed system, ε*ε 0 *S is a constant, only the capacitance and the distance d are variables, and there is an obvious linear negative correlation, so measuring the capacitance value can know the d value to be understood. The monitoring host 2 controls the electromagnet 15 to work, and the electromagnet 15 generates electromagnetic suction to adsorb the probe 12 to press down on the abdominal wall skin; within a short range, the electromagnetic suction can be simplified as F m =η*d; where F m is the electromagnetic force; η is the electromagnetic constant;

[0043] When the electromagnetic suction intervenes and is not fixed on the abdominal wall skin, the nail head leaves the top cover to form a new balance, F m= f sn + G 钉头 ; At this time, f s1 = k*(d 1 -d 0 );

[0044] When the electromagnetic suction is fixed on the abdominal wall skin, the nail head leaves the top cover to form a new balance, F m= f s2 +G 钉头+ f 腹壁0 ; At this time, f s2 = k*(d 2 -d0 ); where f 腹壁 is the force exerted by the abdominal wall on the probe 12;

[0045] When the electromagnetic force intervenes and is fixed on the abdominal wall skin, the abdominal wall hardness changes, the nail head leaves the cap top, and a new balance is formed; F m= f s2 + G 钉头+ f 腹壁n；

[0046] At this time, f s3 = k * (d 3 - d 0 ) ; Let △f 腹壁= f 腹壁n- f 腹壁0； All other items are already known items, so the required △f 腹壁 is a knowable item;

[0047] (6) The monitoring host 2 controls the electromagnet 15 to stop working. The detection frequency is generally once every 4 hours during regular doctor rounds, and the set frequency is generally once every 1 hour or 2 hours. For patients with acute abdominal pain, it can be increased to 2 or 3 times per hour or even more according to the doctor's needs. The present invention calculates the corresponding abdominal wall tension through the moving distance of the probe 12, provides an objective and reliable index for the monitoring of abdominal wall tension, and effectively improves the accuracy and authenticity of the monitoring results.

[0048] The present invention has the following advantages: ① The inspection results are objective and reliable; ② It can dynamically monitor the abdominal wall tension, timely detect changes in the condition, make an early diagnosis and take early intervention treatment, improving the curative effect and survival rate of patients; ③ It reduces the workload of medical staff, reduces repeated abdominal examinations, and reduces the incidence of cross-infection; ④ It reduces the frequency of imaging examinations and reduces the radiation exposure of patients; ⑤ Bedside examination reduces the in-hospital transfer of patients; ⑥ It is simple to operate, low in cost, and easy to promote.
