PERISTALTIC PUMP ABSTRACT OF THE DISCLOSURE This invention concerns a medical peristaltic pump. The purpose of the invention is to improve the pumping and sealing qualities of such pump as well as to increase the flexibility of use thereof whilst maintaining a high level of security. This purpose is achieved with the help of a peristaltic pump in at least three modules, permitting administration of a liquid substance and including pumping means (20) housed in a first module (36; 172) allow- ing compression of at least one tube (28; 28a; 28b) connect- ing a reservoir (30) for storing said liquid substance to the output (32) of the pump, such compression being effected against at least one support piece (34) forming a second module (38, 174), such first and second modules being provided with first positioning means and first assem- bly means (128) in a manner to define a set of two modules in which there is crushing of the tube necessary and suffic- ient to pump said liquid substance, said set of two modules and a third module (40, 176) being provided with second positioning means and second assembly means (148) in a manner such that, once assembled, the third module (40, 76) assures sealing of the pumping means (20). :: : :
