Composite multifunctional three-dimensional heart protection cover

Abstract

The invention relates to a composite multi-functional three-dimensional heart protection cover. According to the scheme, the composite multi-functional three-dimensional heart protection cover comprises a non-elastic airtight outer cover, wherein the shape of the non-elastic airtight outer cover is matched with that of a heart; an opening is formed in the upper portion of the non-elastic airtight outer cover; a medical elastic silica gel layer is arranged in the outer cover; an air vent is formed in the outer cover and is connected with space between the outer cover and the medical elastic silica gel layer; a ventilating cover which covers the air vent is arranged on the inner side surface of the outer cover; the air vent is connected with a device capable of sucking and inflating continuously; an ice blanket is adhered to the inner side of the medical elastic silica gel layer; a temperature-measuring electrode is arranged on the inner layer of the ice blanket; a cloth layer is adhered to the inner layer of the ice blanket; a plurality of pace-making electrodes are distributed on the inner side surface of the cloth layer; wires of the pace-making electrodes are placed between the cloth layer and the ice blanket; and ends of the wires extend out of the outer cover via a combined position between the cloth layer and the upper portion of the ice blanket. Pressure is applied to the heart of a patient and released from the heart of the patient continuously with the aid of gas, electrophysiological levels of the patient can be monitored from a plurality of portions of the patient, required electrical stimulation can be given to the patient, and the temperature of the heart of the patient can be constant in a surgery process.

Description

technical field [0001] The invention relates to the field of cardiopulmonary bypass surgery, in particular to a composite multifunctional three-dimensional heart protective cover. Background technique [0002] At present, when performing cardiopulmonary bypass surgery, it is necessary to cool the patient's whole body to about 30°C, and then block the ascending aorta. It is necessary to cool the heart to 8-10°C and keep it for 30min-6h. The infusion tube at the root is filled with 4°C cold cardioplegia solution (10-15ml / kg), and at the same time, the ice debris in the heart bud cools down, so that the heart stops rapidly; however, the operation needs to be stopped when the cold cardioplegia solution is infused, and When the ice chips cool down, it is easy to stab or frostbite the surface of the heart, the conduction bundle, and the phrenic nerve, and it is necessary to add ice chips or infuse cold cardioplegia intermittently for many times during the whole process, which is i...

[0002] At present, when performing cardiopulmonary bypass surgery, it is necessary to cool the patient's whole body to about 30°C, and then block the ascending aorta. It is necessary to cool the heart to 8-10°C and keep it for 30min-6h. The infusion tube at the root is filled with 4°C cold cardioplegia solution (10-15ml / kg), and at the same time, the ice debris in the heart bud cools down, so that the heart stops rapidly; however, the operation needs to be stopped when the cold cardioplegia solution is infused, and When the ice chips cool down, it is easy to stab or frostbite the surface of the heart, conduction bundle, and phrenic nerve, and it is necessary to add ice chips or infuse cold cardioplegia intermittently for many times during the whole process, which is inconvenient to use and the heart temperature is not easy to control

[0003] At present, when undergoing cardiopulmonary bypass surgery, especially for patients with long operation time and poor myocardial protection, if a heart that has stopped beating needs to be paced, it is often necessary to give the heart a primitive power. The existing technology is mainly achieved by manually pressing the heart. , this auxiliary method mainly has the following disadvantages: uneven compression, easy to aggravate heart damage, and unable to achieve long-term compression; secondly, in patients with low cardiac output, it is generally necessary to perform extracorporeal circulation to assist cardiopulmonary function. Many serious complications such as blood cell destruction, infection, and bleeding cannot be turned around for a long time; in addition, in special cases, doctors do not have much physical strength to perform long-term effective heart compressions

[0004] The traditional ECG pacing electrodes require the doctor to hold the electrodes for multi-directional detection one by one, and place the electrodes, which is inconvenient to use; at the same time, it is very difficult to locate due to the beating heart, resulting in the inability to accurately locate; the existing technology cannot realize multiple parts at the same time.
