Embodiment 1
[0029] Adult Temporary Implantable Heart Pump (Vascular Type)
[0030] The main structure consists of a one-way pump 1, a blood flow catheter 2, a balloon inflation and deflation catheter 3, and a pressure device 4 ( figure 1 )constitute. Described one-way pump, its periphery is cylindrical air bag 6 ( image 3 c), the length is 50 mm, and the air bag 6 can be inflated and deflated through the air bag inflation and deflation catheter 3 . The one-way pump has a blood flow channel 5 in it, and the outlet and inlet diameters of the blood flow channel are 30mm, which are trumpet-shaped, which is beneficial to reduce the blood flow resistance ( image 3 c). The one-way pump has a one-way flap 9 in the blood flow channel, which can be opened and closed in one direction to ensure the one-way flow of blood flow. The one-way valve adopts a mechanical valve, which opens and closes automatically with the blood flow, and has good airtightness. Described blood flow conduit, total len...
Embodiment 2
[0034] Temporary implantable heart pump for adults (cardiac type)
[0035] The main structure consists of a one-way pump 1, a blood flow catheter 2, a balloon inflation and deflation catheter 3, and a pressure device 4 ( figure 1 )constitute. Described one-way pump, its periphery is spherical inflatable bag 6 ( image 3 d), the diameter is 30 mm, and the air bag 6 can be inflated and deflated through the air bag inflation and deflation catheter 3 . The one-way pump has a blood flow channel 5 inside, and the outlet and inlet diameters of the blood flow channel are 20 mm in a trumpet shape, which is beneficial to reduce the blood flow resistance ( image 3d). The one-way pump has a one-way flap 9 in the blood flow channel, which can be opened and closed in one direction to ensure the one-way flow of blood flow. The one-way valve adopts polymer synthetic material valve, which opens and closes automatically with the blood flow, and has good airtightness. The blood flow condu...
Embodiment 3
[0039] Children's Temporary Implantable Heart Pump (Heart Type)
[0040] The main structure consists of a one-way pump 1, a blood flow catheter 2, a balloon inflation and deflation catheter 3, and a pressure device 4 ( figure 1 )constitute. Described one-way pump, its periphery is spherical inflatable bag 6 ( image 3 d), with a diameter of 20 mm, the air bag 6 can be inflated and deflated through the air bag inflation and deflation catheter 3 . The one-way pump has a blood flow channel 5 in it, and the outlet and inlet diameters of the blood flow channel are 15mm, which are trumpet-shaped, which is beneficial to reduce the blood flow resistance ( image 3 d). The one-way pump has a one-way flap 9 in the blood flow channel, which can be opened and closed in one direction to ensure the one-way flow of blood flow. The one-way valve adopts polymer synthetic material valve, which opens and closes automatically with the blood flow, and has good airtightness. The blood flow co...
