Embodiment 1

[0072] like figure 1 As shown, a pneumatic balloon heart assist device includes a cup-shaped balloon 10 and a ventilation duct 20. The sealed inner cavity 11 of the balloon communicates with the inner cavity 25 of the ventilation tube. The cup-shaped balloon 10 is composed of a balloon inner wall 12 and The outer wall of the balloon is composed of 13. The cup-shaped balloon 10 is sleeved outside the left and right ventricles of the heart 40, and assists the heart to contract when the ventilation tube 20 is inflated and deflated. This embodiment may have an opening structure 16, which is not shown in this sectional view.

[0073] In addition, an embodiment without an opening structure is also possible, and the rest of the design is the same as this embodiment.

Embodiment 2

[0075] like figure 2 As shown, a pneumatic balloon heart assist device includes a cup-shaped balloon 10, a ventilation duct 20 and a belt-shaped fixing structure 31 on the side of the cup mouth. Shaped balloon 10 is made up of balloon inner wall 12 and balloon outer wall 13. The cup-shaped balloon 10 is sleeved outside the left and right ventricles of the heart 40, and assists the heart to contract when the ventilation tube 20 is inflated and deflated. During thoracotomy, fix the band-shaped fixing structure 31 on the side of the cup mouth on the chest wall, and the cup-shaped balloon 10 can be fixed on the ventricle surface, so as to prevent the cup-shaped balloon 10 from being damaged during the beating of the heart 40 and the ventilating process of the cup-shaped balloon 10. Balloon displacement. This embodiment may have an opening structure 16, which is not shown in this sectional view.

[0076] In addition, an embodiment without an opening structure is also possible, ...

Embodiment 3

[0078] like image 3 As shown, a pneumatic balloon heart assist device includes a cup-shaped balloon 10, a ventilation tube 20 and a fixed structure 32 on the wall of the bag. The capsule 10 is composed of a balloon inner wall 12 and a balloon outer wall 13. The fixed structure 32 on the capsule wall is composed of a fixing rod 332 and an elongated bag 321 on the capsule wall. The elongated bag 321 on the capsule wall has a thin Long bag opening 323. The cup-shaped balloon 10 is sleeved outside the left and right ventricles of the heart 40, and assists the heart to contract when the ventilation tube 20 is inflated and deflated. This embodiment can be placed through the apical incision. When inserting, the fixed rod 322 can be inserted into the cup-shaped balloon 10 in advance, or the fixed rod 322 can be withdrawn from the cup-shaped balloon 10 first. The cup-shaped balloon 10 is sent to a predetermined position by pushing in the fixing rod 322 , and the ventricle of the he...

Abstract

The invention discloses a pneumatic type balloon heart assisting apparatus, which comprises an annular balloon and vent tubes, wherein the inner wall and the outer wall of the balloon are made from an elastic material; or the outer wall of the balloon is made from a ductile and non-elastic material; or the outer wall of the balloon is made from a shaped ductile and non-elastic material; the balloon is provided with a single compartment; or the balloon is provided with 2-8 partition compartments and some of the partition compartments fail to communicate while some of the partition compartments communicate; the balloon is connected to the 1-16 vent tubes; the various partition compartments can be connected to different vent tubes; some of the partition compartments can be provided with separating straps therebetween; an opening structure can be arranged on the balloon wall; the side, close to a cup rim, of the balloon is provided with strip-shaped fixing structures; a fixing structure, which is composed of a slender bag and detachable fixing rods, is arranged on the outer wall of the balloon; the balloon can be represented as a half-side cup or a single balloon; electrocatdiogram sensing parts are arranged on the balloon wall; a cardiac pacing part is arranged on the balloon ball; and pressure sensing parts are arranged on the balloon wall. The apparatus can take an assisting effect on systole and diastole; and the apparatus can limit cardiac dilatation and sense electrocatdiogram and cardiac pacing.

Description

technical field [0001] The invention relates to a pneumatic balloon heart assist device, which belongs to the technical field of medical instruments. Background technique [0002] After sudden cardiac arrest, clinically, chest compressions + artificial respiration are used for cardiopulmonary resuscitation. Prolonged chest compressions can lead to rib fractures and even damage to abdominal organs, resulting in death of the patient. If a patient with a chest fracture requires CPR, open-chest compressions are required. [0003] Low cardiac output syndrome after cardiac surgery is a common complication and requires high-dose drug therapy and / or device-assisted therapy (including aortic balloon pump, ventricular assist device, and extracorporeal membrane oxygenation, etc.). Severe chronic or acute heart failure is also a common clinical disease, which requires high-dose drug therapy and / or device-assisted therapy (including cardiac resynchronization therapy, ventricular assist...
