the gynecological secretion sampling device further comprises a control module, in order to further reduce discomfort of a user, m first pressure-sensitive sensors are arranged on the inner wall, away from the second air sac cavity, of the first air sac cavity 201, are in signal connection with the control module through leads, detect the pressure of the first air sac cavity 201 contacting with multiple point positions of vaginal tissues through the m first pressure-sensitive sensors, and give the control module a comfortable interval;
if the pressure of the point location is detected to be greater than the maximum value of the comfort zone, it indicates that the stress response of the vaginal tissue on the point location is too large, and the pressure on the point location is in the comfort zone by adjusting the air pressure in the first air bag cavity 201, so as to reduce the stress response of the vaginal tissue and reduce the discomfort;
and when the pressure of the point location is smaller than the minimum value of the comfortable interval, it indicates that the first balloon cavity 201 on the point location is not completely attached to the vaginal tissue, and the pressure on the point location is in the comfortable interval by adjusting the air pressure in the first balloon cavity 201, thereby ensuring the stability of the support structure of the barrier-free tunnel.
Specifically, the first pressure-sensitive sensor may use technical means commonly used in the prior art, such as technical solutions disclosed in publication numbers CN103759867B, CN103743438B, CN108917992B, and the like, and will not be described herein in detail.
In the third embodiment, the first step is that,
the present embodiment is further described in the above embodiments, it should be understood that the present embodiment includes all the technical features and is further described in detail:
in order to ensure the stability of the unobstructed tunnel and reduce the stress response of vaginal tissues, n second pressure-sensitive sensors are arranged in the second balloon cavity 202, the second pressure-sensitive sensors are identical to the first pressure-sensitive sensors in structure and arrangement mode, and the second pressure-sensitive sensors are arranged around the inner surface of the second balloon cavity 202 corresponding to the unobstructed tunnel;
the control module judges whether the comfort value is in the comfort interval according to the detected pressure, and the calculation method comprises the following steps:
Comfort(F1,F2)＝α*W(F1)+β*W(F2)，
Comfort(F1,F2)∈[a,b]
wherein, F1Pressure detected for said first pressure-sensitive sensor, F2For the pressure detected by said second pressure-sensitive sensor, Comfort (F)1,F2) Represents a comfort value, [ a, b]W (F) for the empirically known comfort zone1) Is the degree of filling of first balloon lumen 201, W (F)2) Is the filling degree of second balloon lumen 202, α, β are weighting factors and α + β is 1;
the filling degree of the first balloon cavity 201 is calculated by:
the filling degree of second balloon cavity 202 is calculated in the following manner:
wherein, F1iFor the pressure detected by the ith first pressure-sensitive sensor, F1iMAXIs the pressure detected by the ith first pressure sensitive sensor when the first balloon lumen 201 is inflated very much, F2jFor the pressure detected by the jth second pressure-sensitive sensor, F2jMAXIs the pressure detected by the jth second pressure sensitive sensor when the second balloon lumen 202 is inflated to the extreme.
In the preferred embodiment, since the device is used for sampling, the priority of stability of the unobstructed tunnel is higher than the emergency response of vaginal tissue, that is, the priority of air pressure in the first balloon cavity 201 is higher than the priority of air pressure in the second balloon cavity 202 during adjustment, so α ≧ β.
As shown in fig. 9, a satisfaction questionnaire for statistics of the usage of the sampling device of the present application and a plurality of prior art in five hospitals shows that the satisfaction of the present application is higher than that of other sampling devices of the prior art, and the satisfaction is over 50%.
