Dual-head coronary artery direct perfusion tube

Abstract

The invention relates to the technical field of medical devices, in particular to a dual-head coronary artery direct perfusion tube, which is composed of a handle, a left coronary artery perfusion head, a hard connecting rod, a high-density right coronary artery perfusion head and a soft perfusion tube. As that weight of the right coronary artery perfusion head is several time of that of the leftcoronary artery perfusion head, the right coronary artery perfusion head can be naturally lowered to the right coronary artery orifice and position under the action of gravity. As that double-headed coronary artery direct perfusion tube of the invention is use, the left coronary artery and the right coronary artery can be simultaneously perfusion, the perfusion time is shortened by half, the wholeoperation time is greatly shorten, the operation risk can be reduced, and great benefits are brought to the patients. The double-headed coronary artery direct perfusion tube of the invention can simultaneously perfusion the left coronary artery and the right coronary artery, thus shortening the perfusion time by half.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a double-ended coronary artery direct perfusion tube. Background technique [0002] During cardiopulmonary bypass surgery, it is necessary to directly perfuse the left and right coronary arteries with cardioplegia and protective fluid. Conventional coronary perfusion tubes are generally composed of a handle and a perfusion head, and are used for unilateral perfusion. Different products are required to perfuse the left and right coronary arteries. The difference between the two is mainly the angle of the perfusion head. But because of the narrow coronary artery, and in order not to damage the blood vessels, the perfusion flow rate should not be too high, so it is very time-consuming to use two products to perfuse the left and right coronary arteries respectively. It usually takes 5-10 minutes to perfuse one side, and double Side takes 10-20 minutes. In the prior art, the...

Problems solved by technology

But because of the narrow coronary artery, and in order not to damage the blood vessels, the perfusion flow rate should not be too high, so it is very time-consuming to use two products to perfuse the left and right coronary arteries respectively. It usually takes 5-10 minutes to perfuse one side, and double Side takes 10-20 minutes

In the prior art, there is a lack of a coronary perfusion tube that is convenient to use, does not damage blood vessels, and can reduce the time-consuming perfusion in cardiac surgery
