[0025] figure 1 The structure of the ostomy appliance 100 of this embodiment in an expanded state is shown. The ostomy appliance 100 of this embodiment includes a support unit 10 and a recovery unit 20 connected to the proximal end of the support unit 10 . The support unit 10 is mainly used to support the interatrial septal tissue; the recovery unit 20 is used to recover the entire ostomy appliance from the body.

[0026] see also Figure 1 to Figure 3 , the supporting unit 10 includes a supporting part 11 and a fixing part 14 . The supporting part 11 is used to support the opening of the interatrial septum to stabilize the shape of the opening; the fixing part 14 is used to fix the supporting part 11 so that the supporting part 11 will not fall off from the opening of the atrial septum. Such as figure 2 As shown, the supporting part 11 includes a plurality of diamond-shaped supporting pieces 110 connected end to end. The support member 110 can be compressed in the circu...

[0040] Figure 7 It is a schematic structural diagram of an ostomy appliance 200 according to the second embodiment of the present invention. The ostomy appliance 200 of this embodiment is basically the same as the ostomy appliance 100 of the first embodiment, except that the second fixing part 33 extends away from the axis of the support part 31 from the distal end of the connector 42 and then approaches the support part 31 The axis is extended, that is, the second fixing part 33 is a protruding structure on the connecting part 42 close to the supporting part 31 .

[0041] In the ostomy appliance 200 of this embodiment, a part of the connecting piece 42 is directly designed as the second fixing piece, and the overall structure is simpler, which facilitates the release and recovery of the ostomy appliance 200 .

[0042] The operation of the release process and recovery process of the ostomy appliance 200 in this embodiment is the same as that in the first embodiment, and will...

Abstract

The present invention provides an ostomy appliance, comprising a support unit, the support unit includes a support portion and a fixing portion, the fixing portion includes a first fixing portion connected to the distal end of the support portion, and the first fixing portion It includes a plurality of first fixing parts, the proximal end of the first fixing part is connected with the distal end of the support part, the distal end of the first fixing part is away from the support part and can be turned radially outward to form a curl structure. In the ostomy appliance provided by the present invention, the fixing part can be turned outwards to form a curled structure, and the fixing part forming the curled structure will not cause stab wounds to the tissue; and the distal end of the fixing part can be stretched from the curled structure to a straight line structure under force , to facilitate the recycling of ostomy appliances, and avoid the human body's rejection reaction due to long-term foreign body implantation.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an ostomy device. Background technique [0002] Heart failure is a complex clinical syndrome of impaired ventricular filling or ejection due to any structural or functional abnormality of the heart, and its main clinical manifestations are dyspnea and fatigue, as well as fluid retention. Heart failure, as a serious stage in the development of various heart diseases, is becoming the most important cardiovascular disease worldwide. [0003] Heart failure can be divided into diastolic heart failure and systolic heart failure. Diastolic heart failure refers to the reduction of ventricular relaxation and compliance in the case of normal ventricular systolic function, resulting in reduced ventricular filling volume and increased filling pressure, resulting in pulmonary and systemic circulation congestion syndrome. Diastolic heart failure causes increased pressure in the left atrium and...
