Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically a portable extracorporeal circulation support device for elderly patients with heart failure. Background Technology

[0002] Heart failure is a severe and end-stage of various heart diseases, especially for elderly patients who have poor cardiac reserve and high mortality rates during acute attacks. Extracorporeal circulation support devices, such as extracorporeal membrane oxygenation (ECMO) and ventricular assist devices (VAD), are important technologies for saving the lives of patients with severe heart failure. They are mainly used to treat patients with end-stage heart failure, serving as a "bridge" before heart transplantation or as an "endpoint treatment" when transplantation is not possible, in order to maintain blood circulation, prolong patient life, and improve their quality of life. For elderly patients with heart failure, due to their often multiple underlying diseases, poor surgical tolerance, and scarcity of heart donors, VADs are particularly significant as an effective long-term mechanical circulatory support solution. Currently, mainstream long-term extracorporeal circulation assist devices (such as left ventricular assist devices, LVADs) mainly consist of an internal blood pump, a percutaneous lead, and an external controller and battery pack. The basic working principle is as follows: the blood pump is surgically implanted into the patient's chest cavity. The inflow tube of the blood pump is connected to the apex of the left ventricle, and the outflow tube is connected to the ascending aorta. Driven by the controller, the blood pump draws blood from the left ventricle and pumps it into the aorta, thereby directly reducing the load on the left heart and maintaining systemic blood circulation. After the operation, the patient needs to carry an external controller and two rechargeable batteries for life. The controller supplies power to the internal blood pump and controls its operation through a percutaneous lead that passes through the abdominal wall. However, existing portable VAD systems still have significant drawbacks and challenges for elderly patients with heart failure. For example, they are not portable and comfortable enough. Although they are called "portable", the total weight and size of the controller and battery pack are large. Patients sometimes need to place them outside, such as when using the toilet. It is inconvenient to carry them with them and they need to place them outside. Not all places have a platform for patients to place them, which makes it inconvenient to use and causes trouble for patients.

[0003] Therefore, a portable extracorporeal circulation assist device for elderly patients with heart failure is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a portable extracorporeal circulation assist device for elderly patients with heart failure, in order to solve the problem mentioned in the background art that patients sometimes need to place it externally during use, such as when using the toilet, as it is inconvenient to carry it with them and they need to place it outside. However, not all places have a platform for patients to place it, which makes it inconvenient to use and causes trouble for patients.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The auxiliary device body has a T-shaped connector on its surface, and a mounting base is mounted on the surface of the T-shaped connector. A suction cup support is fixedly mounted on the surface of the mounting substrate; A suction cup is disposed at one end of the suction cup support away from the mounting substrate, and the suction cup is used to adsorb the auxiliary device body onto a smooth surface. By setting up suction cup supports and suction cups, when there is no platform for patients to place auxiliary devices, patients can choose a relatively smooth wall surface, attach the suction cups to the wall surface, and fix the auxiliary device on the wall surface, thereby achieving the purpose of placing the auxiliary device and improving the convenience of using the auxiliary device. At the same time, by setting up T-shaped connecting seats, the mounting base can be detachably installed on the T-shaped connecting seats, allowing patients to choose whether to install suction cups according to their needs.

[0006] Preferably, a shoulder strap is fixedly connected to the surface of the main body of the auxiliary device, and the length of the shoulder strap is adjustable; By setting up a carrying strap, it is easy for patients to carry the auxiliary device on their backs. By adjusting the length of the carrying strap, it can be adapted to patients of different body sizes to carry it on their backs or to be carried by their hands.

[0007] Preferably, one end of the T-shaped connector is provided with an inlet angle.

[0008] Preferably, the surface of the mounting base plate is provided with a control groove and a T-shaped connecting groove.

The T-shaped connecting groove is provided on the side of the mounting base plate close to the main body of the auxiliary device. The mounting base plate is slidably connected to the T-shaped connecting seat through the T-shaped connecting groove. An elastic plate is fixedly connected to the end of the mounting base plate away from the control groove. At least two sets of control shaft brackets are fixedly mounted on the surface of the mounting base plate.

[0009] Preferably, a positioning block is fixedly installed on the side of the elastic plate near the T-shaped connector, and a pull plate is fixedly connected to the end of the elastic plate away from the mounting base plate. The pull plate is used to control the elastic plate to tilt.

[0010] Preferably, two sets of suction cup supports are provided, the suction cup supports are fixedly connected to the mounting base plate, and a retaining ring is fixedly installed at the end of the suction cup support away from the mounting base plate.

[0011] Preferably, the suction cup has ventilation holes on its surface, a suction cup rod is fixedly connected to the surface of the suction cup, the suction cup rod passes through the retaining ring and extends into the interior of the suction cup support, the surface of the suction cup rod has a rod clearance groove, a control shaft is inserted into the interior of the suction cup rod, and the surface of the suction cup rod is slidably sleeved on the sliding sleeve.

[0012] Preferably, a first compression spring is provided between the sliding sleeve and the retaining ring, and an elastic sealing ring is fixedly connected to one end of the sliding sleeve near the suction cup, the elastic sealing ring sliding through the retaining ring.

Under the elastic force of the second compression spring, the lever is engaged between the limiting posts and the inner wall of the control groove. At the same time, the first cam pushes the elastic sealing ring closer to the suction cup through the sliding sleeve to close the vent hole.

When it is necessary to remove the auxiliary device body 1, according to the above steps, the lever 72 is turned in the opposite direction. Under the rebound action of the first compression spring 6, the elastic sealing ring 531 separates from the suction cup 5. At this time, air enters the inside of the suction cup 5 through the vent 51, balancing the air pressure inside the suction cup 5, thereby achieving the purpose of removing the auxiliary device body 1.
