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...

[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...

[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...

Abstract

The invention discloses a temporary implantable cardiac blood pump. The blood pump includes a one-way pump. An inner cavity of the one-way pump is a blood channel, and an outer cavity of the one-way pump is an inflatable bag; the blood flow channel is provided with a blood inlet and a blood outlet and internally provided with a one-way valve; the inflatable bag is connected with an air bag charging and discharging catheter; the blood flow channel is communicated with a blood flow catheter which is provided with a blood flow catheter blood storage cavity; the blood pump further includes a pressure device, and the pressure device is detachably connected with the end, away from the blood flow channel, of the blood flow catheter. The blood pump is mainly used for rescuing patients with cardiacarrest, replaces cardiac ejection, can pump in and pump out blood from the heart or the major artery, achieves the cardiac ejection function, and maintains the body' blood supply.

Description

technical field [0001] The invention belongs to the field of medical materials, and specifically relates to a temporary implantable heart pump, which is expected to play an important role in clinically rescuing patients with severe hemodynamic disorders such as cardiac arrest, bradycardia, and ventricular fibrillation. Background technique [0002] Cardiac arrest, cardiac ejection stops, blood flow in the body's blood vessels is still, brain, lung, kidney and other important organs are ischemic, hypoxic, and dysfunctional. Immediate cardiopulmonary resuscitation is required to restore blood supply and save lives. Chest compression is the most basic rescue method in cardiopulmonary resuscitation. By pressing the chest cavity, it can change the pressure of the chest cavity, promote the outflow and return of blood in the heart, and ensure the blood supply of important organs. However, its effect is limited and only in a short period of time. Maintain part of the blood supply to...
