Problems solved by technology

[0010] 1. Passivity of treatment regulation: neither CSD nor Heartnet can carry out active clinical intervention. Once implanted in the body during treatment, it is difficult to adjust and control. Carry out quantitative, timing, real-time, anytime, and timely artificial regulation;
[0011] 2. Unity of treatment methods: LVAD, CSD, Heartnet, and QVR have obvious singleness in treatment, and can no longer be organically combined with other medical methods, especially direct drug intervention or electrical stimulation. Adequate, effective and straightforward combination of effective drug treatments;
However, LVAD, CSD, Heartnet, QVR and other devices have no effective methods to directly and organically combine themselves with the above-mentioned various treatment methods or technologies conveniently, quickly and economically.
Therefore, the clinical efficacy and application potential of the current main heart failure treatment devices such as LVAD, CSD, Heartnet, and QVR are limited.

Embodiment 1

[0062] Example 1 Preparation of Heart Mesh Cover

[0063] (1) Carry out computer-aided design (CAD) modeling using methods routinely used in this field. These designs can be derived from digital image reconstructions of the patient's heart. For example, image data can be obtained through non-invasive scanning of the human body (such as MRI or CT) or fine-layered three-dimensional reconstruction;

[0064] (2) Use liquid silicone, latex, conductive hydrogel, silicone glue, rubber or polymer plastic materials, and use 3D printing technology to print the heart mesh cover;

[0065] or,

[0066] ① Use blue wax, green wax, red wax, black wax, white wax and other materials to make the solid structure of the device with 3D printing equipment;

[0067] ② Soak the blue wax solid structure in liquid silica gel or latex or conductive hydrogel or silicone glue or rubber or polymer plastic material for 1 second to 24 hours;

[0068] ③Take out the above soaked structure, cover it with a c...

Embodiment 2

[0072] Example 2 Attached heart function monitoring system

[0073] An attached heart function monitoring and / or intervention system, a heart support device and a heart function monitoring device, the heart support device is selected from a heart mesh sleeve, and the structure is as follows figure 1 As shown, 1-cardiac mesh, 2-physiological and biochemical sensors, 3-wire, 4-heart function monitoring device. The cardiac support device is coated on the outer surface of the ventricle and / or atrium or the support is attached to the inner surface of the cardiac cavity, the cardiac function monitoring device is connected with physiological and biochemical sensors, and the physiological and biochemical sensors are attached to the inner and / or outer surface of the cardiac support device , or embedded in the cardiac support device, or filled inside the cardiac support device.

Embodiment 3

[0075] The basic structure is the same as that of Example 2. The net cover is composed of hollow tubes. All the hollow tubes are completely connected or form several independent areas. The inside of the area is interconnected, but the areas are not connected. The physiological and biochemical sensor paste Attached to the inside or outside of the net, the wires of the physiological and biochemical sensors pass through the hollow tube of the net and are connected to the heart function monitoring device from the end of the net. structured as figure 2 As shown, when the mesh is attached to the outer surface of the ventricle and / or atrium, the physiological and biochemical sensors are attached to the inside of the mesh ( figure 2 a), when the mesh sleeve is attached to the inner surface of the heart cavity, the physiological and biochemical sensors are attached to the outside of the mesh sleeve ( figure 2 b).

Abstract

The invention discloses an attaching-type heart function monitoring and / or intervening system. The attaching-type heart function monitoring and / or intervening system comprises a heart support device and a heart function monitoring device and / or intervening device, wherein the heart support device covers the outer surface of the heart ventricle and / or the heart atrium or attaches to the inner surface of the heat in a supporting manner, the heart function monitoring device is connected with a physiological and biochemical sensor, the physiological and biochemical sensor detects or senses the change of the physiological and biochemical parameters on the inner surface or the outer surface of the heart, and transmits the information to the heart function monitoring device through the wireless technology or the wired technology; the intervening device is selected from one or more of a pressure intervening device, an electric / magnetic stimulation intervening device and a medicine intervening device. With the system, the direct and accurate monitoring for the physiological and biochemical functional indexes of the local intracardiac / extracardiac membrane and the direct and accurate specific drug delivery for the local intracardiac / extracardiac membrane or the electric / magnetic stimulation or heart ventricle pressure regulation can be realized, monitoring and treatment are organically combined, and thus the heart failure state of patients can be improved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a device for monitoring and treating various types of heart diseases after being implanted on the outer surface of the heart or in the heart cavity, and is especially suitable for the diagnosis and treatment of heart failure or various myocardial diseases. At the same time, it can also be applied to the treatment and diagnosis of lung, kidney, liver, spleen, stomach, bladder and other organ diseases. Background technique [0002] Heart failure is a common pathophysiological state in which most heart lesions develop to the end stage. It is a clinical syndrome of impaired ventricular filling or ejection ability caused by cardiac structure and dysfunction. Its basic manifestations are dyspnea and fatigue, exercise tolerance Restricted, fluid retention can also occur and can lead to pulmonary congestion and peripheral edema. [0003] Although some progress has been made ...
