Disclosed is a pessary for transvaginal haemostasis, wherein the radial dimension of a balloon body (1) can be changed to form a relatively large pressure on a vaginal wall, thereby achieving the effect of high-pressure haemostasis. The pessary for transvaginal haemostasis comprises: the balloon body (1), being made of an expandable material, the balloon body (1) having a cavity (11), the cavity (11) having a filling hole (12) so that a fluid can be filled into or drawn out of the cavity (11) through the filling hole, the balloon body (1) having a first end (1a) and a second end (1b), the balloon body (1) having at least one hollow passage (13), the passage (13) running through the first end (1a) and the second end (1b) of the balloon body (1) and not being in communication with the cavity (11), an outer surface of the balloon body (1) having at least one channel (14), and the channel (14) also running through the first end (1a) and the second end (1b) of the balloon body (1)； and a support body (2) having a coupling end (2a) and a support end (2b), the coupling end (2a) being coupled to the second end (1b) of the balloon body (1), the support body (2) having a through hole (21) in communication with the passage (13), and the peripheral surface of the support body (2) having at least one recessed portion (22) corresponding to the channel (14).L'invention concerne un pessaire pour l'hémostase transvaginale, la dimension radiale d'un corps de ballonnet (1) peut être modifiée pour former une pression relativement grande sur une paroi vaginale, ce qui permet d'obtenir l'effet d'hémostase à haute pression. Le pessaire pour l'hémostase transvaginale comprend : le corps de ballonnet (1), étant réalisé en un matériau expansible, le corps de ballonnet (1) ayant une cavité (11), la cavité (11) ayant un trou de remplissage (12) de telle sorte qu'un fluide peut être introduit dans la cavité (11) ou aspiré hors de la cavité (11) à travers le trou de remplissage, le corps de ball
