Description
Technical field
This utility model relates to the quantitative measurement techniques of guarding, is specifically related to a kind of noinvasive multiple spot guarding measuring device.
Background technology
Abdominal cavity is the miracle on evolutionary history, because 8.5 sausage pipes have been stored in slight abdominal cavity of behaving.Similar head, abdominal part also can be thought of as a closed box.There is the pliable and tough border (stomach wall and diaphragm) of individual anchoring (arcus costarum) and hard border (spinal column and pelvis) or part above this chest and fill organ.The part at abdominal part afterbody and back is the solid structure formed by pelvis and back of the body sour jujube.Only the stomach wall in abdominal cavity and barrier film have retractility.
Xiphoid and the costal margin upper bound, between pelvis ilium lower bound, the edge in abdominal cavity represents stomach wall.Stomach wall is divided into: rear wall (back; Usually part back or posterior axillary line back is thought of as), sidewall (limit or side; Usually part between line is thought of as before and after axil) and antetheca is (above; Usually previous section or anterior axillary line veutro is thought of as).In clinical position, only, stomach wall has clinical meaning.
The tensity (also known as hardness) of abdominal muscle when guarding is digital palpation abdominal part determines according to the opposing sense of abdominal muscle.During abdominal touch, the observation measurements of guarding causes the impression grade of press points to weigh by using accurate dynamics to press.Normal person's abdominal part has some tension, but more easily subsiding of touching, claim stomach wall soft.Some pathologic condition can make full abdomen or local guarding increase or weaken.
Guarding increase is divided into following several situation: 1. parietal peritoneum is subject to acute inflammation stimulates the abdominal muscle spasm caused, and stomach wall is stiff, sees acute peritonitis; 2. chronic inflammatory disease stimulates the guarding caused, and that touches has dough kneading sensation, has similar dough kneading sensation, sees tuberculous peritonitis; 3. due to the tolerant increase of intraperitoneal, support swollen stomach wall engender tension, see peritoneal recurrence or abdominal compartment syndrome.Normal abdominal touches, abdomen wall tension increase does not cause pain, and heavy only have a kind of constriction on time.There is title peritoneal irritation sign in abdominal tenderness, rebound tenderness, muscle tonus, prompting abdominal visceral browser diseases associated with inflammation simultaneously.
Guarding reduces many to reduce because of abdominal muscle tension force or caused by disappearing.Full abdomen tensity reduces, and sees Chronic consumptions or after putting ascites in a large number, also sees multipara or patient that is old, dehydration.Local tension degree reduces comparatively rare, how because the stomach wall paralysis of local or defect (as planned abdominal hernia etc.) cause.
Traditional employing abdominal part physical examination assessment abdomen wall tension: 1. guarding inspection: usually adopt pressure maniputation, with the smooth stomach wall of full palmar aspect, then presses in detail with the palmar surfaces of fingers closed up, to judge nervous position and scope; 2. tenderness, rebound tenderness inspection: after tenderness appears in palpation abdominal part, is pressed on painful area with 2 ~ 3 fingers closed up and continues in a moment, is lifted by hands then rapidly, and reaction that those who are investigated have that the pain increased is that rebound tenderness is positive.At present problems faced is the inaccurate of assessment guarding clinically, therefore the error of the diagnosis and treatment disease that causes guarding to change.
Within 2009, abroad deliver a preliminary study in, the people such as VanRamshorst checked the abdominal tension degree of 2 corpse.Same author checked the abdominal cavity of 14 corpses being filled with air in experiment subsequently.They find there is significant correlation (epigastrium area coherence is best) between Intra-abdominal pressure and guarding.In 31%, the Valsalva motion higher than women of the average guarding of experiment in vivo display male, during air-breathing of exhaling, guarding increases.Erect position guarding is the highest, follows by dorsal position and seat.Correct guarding measures the disease causing guarding to change for Diagnosis and Treat important meaning:
Guarding is measured and us can not only be helped to be familiar with the basic parameter of abdominal wall structure, can also give the position and the order of severity that help our quantitative judgement celiac disease.The method of muscle tonus, tenderness, rebound tenderness is all the inspection qualitatively of subjectivity.Those who are investigated's pain discomfort is caused to increase the weight of, for the positive finds by the subjective palpation sensation of examiner or guarding flip-flop.The method of this physical examination causes the sensitivity of check result to increase, and specificity reduces.
