Further, a via hole is provided on the baffle 14; the second guide wire 6 penetrates through the through hole; a limiting structure 15 is arranged on one side, close to the puncture needle 7, of the baffle 14 on the second guide wire 6, and the limiting structure 15 is suitable for preventing a part of the second guide wire 6 connected with the puncture needle 7 from being separated from the protective shell 13 and preventing the puncture needle 7 from being separated from the protective shell 13; in particular, the limiting structure 15 may be a spherical protrusion. Sealing is adopted at the position of the top end of the channel 11 close to the protective shell 13 and the position of the top end of the channel 11 adjacent to the catheter 9 so as to prevent amniotic fluid leakage; further more amniotic fluid was collected. The outside of the seal may also be coated with an epidermal growth factor-releasing medium. A structure similar to the channel 11 is also provided at the position of the first guide wire 5, the second guide wire 6, the catheter 9, the pipeline connecting the first balloon 1 and the first inflation and deflation assembly 3, and the like passing through the corresponding second balloon 2 on the second balloon 2.
The main working process of the amnion puncture, amniotic fluid collection, amnion blocking and induced spawning multifunctional device provided by the application is briefly described as follows: the amniotic fluid enters the puncture needle 7 through the vagina and the cervix, the amniotic sac is punctured to release the amniotic fluid, and meanwhile, the first sac body 1 in the cervix can slowly release the amniotic fluid, so that the abrupt change of pressure is avoided; the amniotic fluid can be collected, accurate measurement is achieved, when the amniotic fluid needs to be stopped, the puncture needle 7 can be retracted, the first bag body 1 can support the amniotic sac, and the function of closing the rupture is achieved.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. And obvious variations or modifications thereof are contemplated as falling within the scope of the present application.
