Description
Technical Field
The embodiment of the invention relates to the technical field of pelvic floor muscle medical equipment, in particular to a system and a method for detecting and evaluating the muscle tension of female pelvic floor muscles.
Background
Pelvic floor dysfunction is the pelvic floor dysfunction caused by weak support of female pelvic floor support tissues due to factors such as degeneration, trauma and the like. Whether a pelvic floor dysfunction disease is treated or not depends on whether the quality of life of the patient is affected. Specifically, pelvic floor dysfunction mainly refers to relaxation or tension of pelvic floor-related muscles, or to a reduction in muscle function caused by injury to pelvic floor muscles due to lumbar, sacral, caudal, or hip arthropathies, i.e., a series of symptoms caused by muscle dysfunction constituting the pelvic floor and changes or injury to the pelvic floor support structure, and is not a dysfunction caused by injury to pelvic organs. Pelvic floor dysfunction aims to study the diagnosis and treatment of diseases caused by defects, injuries and dysfunction of pelvic floor support structures, and vaginal relaxation and other problems can be discovered, intervened and treated early through the detection of pelvic floor muscles.
At present, the related detection of pelvic floor muscles is divided into pelvic floor electrophysiological examination and pelvic floor biomechanical examination; the method has the advantages that the type I muscles and the type II muscles of the pelvic floor muscles are measured and evaluated, and some pelvic floor related dysfunctions caused by muscle relaxation and insufficient muscle strength can be well detected; however, some pelvic floor diseases caused by muscle tension and poor muscle elasticity cannot be effectively detected and discovered, and patients with problems such as pelvic floor pain cannot be effectively evaluated by such detection methods.
In addition, the patients with pelvic floor problems found in clinical practice are roughly divided into two categories: some patients exhibit symptoms of muscle relaxation, such as stress incontinence, prolapse, vaginal relaxation, etc.; the other part is a pelvic floor pain patient with a long disease course, and the pelvic floor muscle is excessively seriously injured to cause spasm of the pelvic floor muscle, so that the problems of pelvic floor pain, uncoordinated sexual life and the like are caused.
The muscle activity of the pelvic floor muscle is judged by detecting the contraction pressure of the inner wall of the vagina, and the further processing of the pressure can know the degree of vaginal relaxation and urinary incontinence.
The tension state of the pelvic floor muscles under the condition of different resistances can be measured through quantitative muscle tension detection, and the indexes of the pelvic floor muscles such as relaxation, elasticity and tolerance can be evaluated through further processing.
The invention patent with patent number CN104770830A and named as female pelvic floor muscle pressure detection device discloses a method for detecting female pelvic floor muscle pressure, which directly measures the pressure value of pelvic floor muscle through a thin film sensor and sends the pressure value to a data terminal for processing. In a pressure detection method and system of a portable pelvic floor muscle training device and a pelvic floor muscle training device, such as patent No. CN110538431A, a method for training and detecting pressure of pelvic floor muscles is disclosed. The method is characterized in that a built-in structure on the vaginal probe acts on an internal pressure sensor, and the pressure sensor transmits a pressure value back to external equipment for judgment and processing.
In a word, the existing pelvic floor muscle health condition evaluation method usually judges the muscle activity of the pelvic floor muscle by detecting the resting or contraction pressure of the inner wall of the vagina, and evaluates the condition of the pelvic floor muscle in a single dimension, so that the accuracy is not enough, and the evaluation index is not comprehensive enough.
Specifically, as shown in the two patents disclosed in the above two patents, the pressure sensor is used to measure the pressure of the vaginal wall, and the activity of the pelvic floor muscle is determined. The scheme has the disadvantages that firstly, the size of the vaginal probe is uniquely determined, but the size of the inside of each female vagina is not necessarily constant, the contact condition of the probe and the inner wall is difficult to unify and correct, secondly, the activity condition of slow muscles is difficult to accurately judge under the condition that pelvic floor muscles are simply rested or randomly contracted, the condition of the muscle tension of the pelvic floor muscles of women cannot be evaluated, and a plurality of parameters need to be detected for comprehensive judgment.

Best mode for carrying out the invention
At present, the related detection of pelvic floor muscles is divided into pelvic floor electrophysiological examination and pelvic floor biomechanical examination; determination and evaluation of the pelvic floor muscles for type I and type II muscles; the method can well detect some related dysfunctions of the pelvic floor caused by muscle relaxation and insufficient muscle strength; however, some pelvic floor diseases caused by muscle tension and poor muscle elasticity cannot be effectively detected and discovered, and patients with problems such as pelvic floor pain cannot be effectively evaluated by such detection methods. The invention is a set of comprehensive detection mode of pelvic floor muscle tension, and makes up the defects of the prior art.
The embodiments of the present invention will be further described with reference to the drawings and the embodiments.
As shown in fig. 1-8, the method for evaluating a system for detecting female pelvic floor muscle tone comprises the following steps:
step 1: the air bag is vacuumized by the deflation and vacuum unit and then is placed in the vagina of the patient; at this time, the pelvic floor muscle tension feedback value which is collected from the vagina and is used as the pressure value inside the air bag is 0mmHg, and the volume of the gas filled in the vacuum state is 0 mL;
step 2: a warm-up stage;
and step 3: detecting in a first stage;
and 4, step 4: detecting in the second stage;
and 5: detecting in a third stage;
step 6: and issuing a detection report, a training scheme and a recommendation.
The warm-up phase comprises: the air cell is used for slowly filling air L with the volume of 1m in 1s to the air bag, and then the air bag stops inflating automatically after reaching the target volume, so that the air bag expands in the vagina and is completely attached to the vaginal wall even if reaching the target volume, and normal detection data are prevented from being influenced due to improper putting operation.
The first stage detection comprises: the air bag is vacuumized by an air discharging and vacuum unit in the vagina, the pressure value in the air bag returns to 0, and the volume value of the charged air returns to 0; slowly inflating the air bag by using an inflation unit at the speed of 1s of gas L which is 1m to reach the target volume, stopping inflating, and recording the pelvic floor muscle tension feedback value when the pelvic floor muscles are in a resting and relaxing state;
the second stage of detection comprises: under the size of the air bag, the detected person performs template and voice prompt to contract pelvic floor muscles according to voice prompt information in a template curve shown in fig. 7, records the whole-course collected data of the stage, and calculates the average value P2 of the maximum value of the 3 times slow muscle stage and the matching degree and variability of the maximum value and the template; recording the whole-course data collected at this stage is collected according to the evaluation indexes of the relevant type I muscles and type II muscles.
The third stage detection comprises: the air bag is vacuumized by an air-releasing and vacuum unit in the vagina, the pressure value in the air bag returns to 0, and the volume value of the filled air returns to 0; the air bag is slowly inflated by the inflating unit at the speed of 1m of air L rushing in 1s, a detected person can feel the expansion of the air bag to the vagina statically in the stage, the detected person actively informs an operation teacher when reaching a tolerance point, the inflation is stopped, and the complete pelvic floor muscle tension feedback value and the volume curve of the inflated air can be recorded in the stage.
The presenting of the detection report, the training scheme and the suggestion comprises the following steps:
calculating and fitting corresponding linear characteristic values in stages; before rest: initial tension volume, target volume tension value; and (3) a continuous shrinkage stage: delta contraction, variability; a tolerance stage: volume tolerated. The specific way to calculate and fit the corresponding linear eigenvalues in stages is shown in fig. 8.
The force produced by muscle cell traction is called muscle tension, and can represent the tension of a muscle in a resting relaxed state. Muscle tone is the basis for maintaining the body in various positions and normal movements, and is manifested in a variety of forms. As the balloon inflation volume increases, characteristic points (initial points; target points, endurance points) appear. A complete tension/volume curve is drawn in the third stage of detection, wherein the size of the vagina of the tested person under the condition of relaxation can be calculated through [ 0-initial point ] appearing in the third stage of detection; the muscle tension curve of the stage (initial point to target point) appearing in the third stage of detection can calculate the current tightness of the vagina, the curve change of the relaxed person is relatively gentle, the influence intervention of pelvic floor muscles on the pressure of the air bag is relatively late, the curve change of the healthy person group with the pelvic floor muscles in the state is relatively steep, the acting force intervention of the pelvic floor muscles on the air bag is relatively early, and the elasticity of the vagina and the pelvic floor muscles can be calculated by the muscle tension curve of the stage (target point to tolerance point) appearing in the third stage of detection.
In the stage (initial point to target point), a linear fitting algorithm is used for fitting a change relation formula (1) of the tension along with the inflation volume:
Y＝B0X+B1(1)；
wherein Y represents the muscular tension of the pelvic floor, and X represents the volume value of the filled gas; b0 denotes the slope of the fitted linear curve and B1 denotes the offset coefficient. The larger the B0, the steeper the curve, and the smaller the B0, the gentler the curve. The population with an over-steep fitting curve is more likely to clinically show a rise, and the population with an over-flat fitting curve slope is clinically shown to show a pelvic floor muscle relaxation; b1 is a negative value, the absolute value of B1 reflects the relationship between the volume value X0 of the gas filled corresponding to the initial pelvic floor muscle tension Y0, and the greater the absolute value of B1, the greater the vaginal volume may be, and the more the pelvic floor muscles are relaxed.
As can be seen from the example shown in fig. 4, the series 1 relaxation characteristic data fitting formula is that for the tension/volume curves of the three typical characteristics corresponding to the three examples respectively: 0.4705 x-4.4703; the fitting formula of the series 2 high-tensile characteristic data is as follows: 1.0616 x-3.6511; the fitting formula of the series 3 normal characteristic data is as follows: 0.6566 x-4.3914.
As can be seen in the example shown in fig. 5, the series 1 relaxation tolerance values are low, the series 2 vaginal poor elasticity tolerance values are low, and the series 3 healthy pelvic floor muscle data tolerance values are good for large pelvic floor muscle elasticity.
Compared with the prior art, the invention detects and evaluates the type I muscles and the type II muscles through pressure detection; the tension state of pelvic floor muscles under different resistance conditions of the muscles in a static and relaxed state can be measured by controlling the inflation quantity and the inflation speed of the air bag, and the relaxation, the elasticity, the tolerance and the like of the muscles can be evaluated; the evaluation dimension is increased so that the result is more accurate.
A system for detecting and evaluating muscle tone of female pelvic floor muscles, as shown in fig. 1, comprising:
the device comprises an air bag, a pressure sensor unit, a flow sensor unit, an analog-to-digital conversion unit, a deflation and vacuum unit, a data calculation and processing unit, a main control unit and an inflation unit;
the pressure sensor unit is communicated with the air bag through an air passage and is used for detecting the pressure value inside the air bag in real time, and the pressure value reflects the pressure value of the inner wall of the female vagina;
