CN102921095A - Novel blood passible balloon for inflating valve or blood - Google Patents

Abstract

A balloon is made to inflate the peripheral air bag from a center guide wire, and a plurality of longitudinally communicated pipe cavities through which blood flow can pass are arranged between the guide wire and the peripheral air bag. When inflation ensures that a narrow region is expanded, blood flow always passes through the pipe cavities so as to be supplied to a far end visceral organ, in an operation process, pulmonary artery far end pressure measurement and oxyhemoglobin saturation measurement can be simultaneously carried out, thus the far end visceral organ ischemic time is reduced, and the narrow section can be more fully expanded so that operation risks are reduced.

Description

A kind of novel passability valve or Angiectasis sacculus

Technical field

[0001] the present invention improves on present traditional peripheral blood vessel dilating sacculus basis, the narrow section two ends keep blood flow unobstructed in the process of balloon expandable stenosed valve or blood vessel so that be expert at, be convenient to observe in the art far-end blood supply on the impact of internal organs, adjust degrees of expansion and make things convenient for pressure measurement in the art.

Background technology

[0002] present, the foley's tube that is applied to clinically annuloplasty band is mainly Tyshak II foley's tube, during use seal wire passed narrow valve, send into inflatable dilatation narrow zone behind the sacculus, then withdraw from pressure measurement behind the sacculus, there are two main drawbacks in this mode, the firstth, in the process of inflation, the narrow section far-end will suspend blood supply, increase the risk of internal organs ischemical reperfusion injuries, second, in order to reduce Ischemia Time, the time of inflation can be controlled at 5-60s, and narrow section is expanded insufficient, or need multi-time inflating, increased the risk of valve in the art or vascular tear.

Summary of the invention

In order to overcome the drawback of existing sacculus, the present invention adopts the mode of hollow, periphery inflation so that in the art in giving the process of airbag aeration, the narrow section far-end still has blood supply.

The technical solution adopted for the present invention to solve the technical problems is: sacculus is made into by central seal wire to the periphery airbag aeration, passes through and there is the straight-through tube chamber of a plurality of stringers to be used for blood flow between seal wire and the periphery air bag.When the inflatable dilatation narrow zone, still have blood flow to pass through in the tube chamber, supply far-end internal organs have reduced far-end internal organs Ischemia Time, and can make the more abundant of narrow section expansion, make things convenient for the measurement of pressure measurement and blood oxygen saturation in the art, reduce operation risk.

1. aerating gasbags among the figure; 2. conduit; 3. side opening; 3. blood flow tube chamber

The specific embodiment:

After seal wire is goed deep into narrow zone, to inflate to 1. aerating gasbags by 3. side openings from 2. conduits, air bag opens expansible narrow zone, and blood flow can flow to the far-end internal organs by 4. blood flow tube chambers simultaneously.

Claims (3)

1. a novel passability valve or Angiectasis sacculus is characterized in that, sacculus are made into the double-layered balloon that periphery is inflated central multi-pipeline UNICOM, so that when inflated was expanded, pathological changes narrow section far-end still had blood to supply.

2. new and improved blood saccule according to claim 1, it is characterized in that, during unaerated, seal wire is extended through blood vessel or valvular heart disease become narrow section, inflate after sending into sacculus, gas enters sacculus from the seal wire side opening, sacculus is propped up, expanded narrow zone, simultaneously because balloon expandable, a plurality of direct pipings of sacculus central authorities are open, so that proximal part blood flows to remote organ by passage.

3. according to claim 1,2 described improvement blood saccules, it is characterized in that, in the expansion narrow section, keep blood smooth, be convenient to the protection of far-end internal organs in the art, be convenient to pressure measurement in the art, reduce operation risk.
