Abstract

The invention provides a three-way valve for a blood pressure collecting device, a preparation method and the blood pressure collecting device. The three-way valve comprises a main body, a valve and an adapting piece, wherein the valve is arranged in the main body, comprises a first through pipe, and is used for switching opening and closing of the main body and the flowing direction of liquid; one or more first grooves are formed in the inner wall of the first through pipe; an adapting opening is formed in the end part of the adapting piece in the direction away from the valve; a connecting piece is arranged at the end part of the adapting piece in the direction close to the valve, and is arranged in the first through pipe; and an adhesive layer is arranged between the connecting piece and the inner wall of the first through pipe. The adapting piece is connected with a power device, the power device drives the valve to rotate, automatic opening and closing of the valve are achieved, and the flowing direction of the liquid can be automatically adjusted. The first grooves are formed in the first through pipe, and the adhesive layer is arranged among the inner wall of the first through pipe, the first grooves and the adapting piece, so that the torque of the valve is increased, and the load capacity of the valve is improved.
