1. A multichamber sphygmomanometer having a chamber selector intended to measure blood pressure, which comprises:
an armlet structurally arranged to surround a limb through which there is blood circulation; a set of inflatable chamber arranged into the armlet, wherein each inflatable chamber has a respective pneumatic connection assigned thereto; an air pressure pump that, provided with a releasing valve means, is able to inflate the inflatable chamber until reaching the necessary compression on the application limb; a manometer able to measure the detected blood pressure, an outer pneumatic tube having a first end coupled to the air pressure pump and the manometer and a second end opposite the first end, the outer pneumatic tube connecting the set of inflatable chambers with the air pressure pump and the manometer, the outer pneumatic tube having a plug connection at the second end, the plug connection being configured as a plug that can be plugged into an opening; and a fixed manual valve selector device connected between the outer pneumatic tube and the set of inflatable chambers arranged in the armlet, wherein the assigned pneumatic connections of the inflatable chambers communicate with the outer pneumatic tube, through the fixed manual valve selector device, the fixed manual valve selector device comprising: at least two outlet selective connections each having an opening into which the plug connection is insertable, wherein each of the at least two outlet selective connections is configured to receive air outputted by the outer pneumatic tube when the air pressure pump is pumped, wherein each of the at least two outlet selective connections is connected to one or more inflatable chambers of the set of inflatable chambers through the fixed manual valve selector device, wherein plugging the plug connection into different ones of the openings of the outlet selective connections connects the air pressure pump to different inflatable chambers through the fixed manual valve selector device, wherein the plug connection is pluggable into one of the openings of the at least two outlet selective connections to establish a connection to one or more inflatable chambers through the fixed manual valve selector device, and the plug connection is separable from the outlet selection connections such that the plug connection can be unplugged from the opening of the one of the at least two output selective connections and then plugged into an opening of another of the at least two output selective connections to establish a connection to a different one or more inflatable chambers, wherein the outlet selective connections have identifiers that associate the different outlet selective connections with the one or more inflatable chambers to which they are connected. |
