Abstract: Provided is a pressure guide wire, including a proximal portion (1), an intermediate portion (2) and a distal portion (12), the intermediate portion (2) is composed of one or more woven layers, wherein each woven layer includes a plurality of woven wires, the distal portion (12) includes a sensor housing (4) that holds a pressure sensor (5) and a head end assembly (11), the head end assembly (11) includes a developing spring (9) and a head end core wire (11) nested within the developing spring (9). The pressure guide wire having such a structure has good flexibility and supportability, meanwhile, the cost of the pressure guide wire can be reduced due to the low cost of the woven wire and the weaving process.

Abstract: A blood flow environment simulation device is disclosed, including: a liquid reservoir (1) for storing liquid; a vascular simulation tube (4); a pump (2) for pumping liquid; a plurality of circulation tubes (7, 11, 12), which form a liquid circulation path together with the vascular simulation tube; and a valve (6) located in the circulation path, having a valve inlet (17) and a valve outlet (18), wherein the area of the valve inlet (17) is variable to change the dynamic parameters of the fluid in the vascular simulation tube (4) over time. The present disclosure also relates to medical equipment that includes a blood flow environment simulation device as described.
