Clinical split type catheter for cardiology

Abstract

The invention discloses a clinical split type catheter for cardiology, and belongs to the technical field of medical supplies. The clinical split type catheter comprises a head tube, a tail tube is integrally formed at the rear end of the head tube, an external tube extends out of the tube wall of one side of the tail tube; a front end tube opening of the external tube communicates with the tail tube through a pore, and an airtight tube is embedded into a rear end tube opening of the external tube; the front end of the airtight tube extends forwards into the head tube along the tail tube, an air inlet head is integrally formed at the position, extending out of a tube body of the rear end of the external tube, of the airtight tube, and the front end of the airtight tube forwards abuts against the rear portion of a sealing interlayer; an air bag A and an air bag B are sequentially arranged on the outer wall of the head tube of the clinical split catheter for the cardiology. When the airbag A on the outer side of the clinical split type catheter for the cardiology is transported to be broken or taken to be broken, the air bag B is reserved behind the head tube of the clinical split type catheter for the cardiology and can be used in cooperation with the clinical split type catheter for the cardiology, so that the situation that an operation is affected after a single air bag A ofthe clinical split type catheter for the cardiology is broken is avoided.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a clinical split catheter in the Department of Cardiology. Background technique [0002] Cardiology, that is, cardiovascular medicine, treats diseases including angina pectoris, hypertension, sudden death, arrhythmia, heart failure, premature beats, arrhythmia, myocardial infarction, cardiomyopathy, myocarditis, acute myocardial infarction and other cardiovascular diseases. In the treatment of cardiovascular diseases, common treatment methods include cardiac stents and vascular stents. Vascular stents refer to placing internal stents in lesion segments on the basis of lumen balloon expansion to support stenotic and occluded blood vessels, reducing The purpose of elastic retraction and reshaping of blood vessels is to maintain smooth blood flow in the lumen. Some internal stents can also prevent restenosis. Mainly divided into coronary stents, cerebrovascular stents, re...

Problems solved by technology

[0005] 1. The existing clinical split catheter in the Department of Cardiology Take a clinical split catheter in the Department of Cardiology with the patent number CN201920377841.2 as an example. This patent relies on the interaction between the steel wire, the silicone ball and the sealing compartment, and the silicone ball is pushed by the steel wire. The sealing compartment of the clinical split catheter in the Department of Cardiology applies an intrusive driving force. Under the force of the steel wire, the clinical split catheter in the Department of Cardiology is pushed into the designated position of the patient's blood vessel under force, but the front end of the steel wire is relatively sharp. It is easy to puncture the septum and catheter and cause damage to the patient's blood vessels, and the thin steel wire is easy to bend during the insertion process, which affects the advancement of the catheter. Therefore, it is necessary to design a safe way to push the catheter. For this reason, we propose a heart Internal medicine clinical split catheter

[0006] 2. The existing split-type catheter for clinical cardiology. Taking a clinical split-type catheter for cardiology with the patent number CN201920377841.2 as an example, this kind of clinical split-type catheter for cardiology is equipped with a balloon on the outside of the tube body. The one-piece catheter can float forward with the floating force of the airbag, but most of these clinical split catheters are equipped with a single airbag. rupture, which in turn affects the normal use of the clinical split catheter in the Department of Cardiology. Therefore, we propose a clinical split catheter in the Department of Cardiology
