Abstract
The utility model discloses a valvular coating film supporting frame which is composed of a cylindrical metal supporting frame and a coating film sewed on the surface of the supporting frame. The utility model comprises an upper part and a lower part, wherein the upper part is composed of the cylindrical metal supporting frame and the coating film which is covered on the surface, the lower end of the coating film is extended out of the supporting frame, and the lower part is composed of the cylindrical metal supporting frame and the coating frame covered on the surface; a part of the coating film material which is extended out of the upper part is arranged in the metal supporting frame at the lower part, and a section of coating frame without the metal supporting frame exists between the metal supporting frames of the upper and the lower parts. The metal supporting frame at the lower part is longer than that at the upper part.
Description
Technical field
This utility model belongs to a kind of medical instrument, relates in particular to a kind of flap valve type overlay film frame.
Background technology
Just there is cardiac structure to be called congenital heart disease unusually during birth, between between the left atrium, is separated with damaged satisfactory atrial septal defect, be separated with damaged satisfactory ventricular septal defect etc. between between right ventricle and the left ventricle.About 1% (0.6%～1.2%) of congenital heart disease sickness rate in normal population, this is a no small numeral, calculates by China's 1,000,000,000 populations, nearly 1,000 ten thousand people suffer from congenital heart disease.
Patent ductus arteriosus about 9%～12% of the cardiopathia of taking the lead.Ductus arteriosus is a pipeline between descending aorta and pulmonary artery, is the important path of fetal circulation.Fetus can not directly be got oxygen from the external world in parent, the effect of lung apnea, so pulmonary artery is before going into lung, go into descending aorta by ductus arteriosus mostly, follow umbilical artery and change oxygen, but blocking-up in time again after the birth makes all Pulmonic blood enter pulmonary circulation to Placenta Hominis, as the mechanism of closing has inborn defective, promptly constitutes clinical patent ductus arteriosus.The present Therapeutic Method of simple patent ductus arteriosus has medical treatment, intervention property catheterization and surgical operation therapy, and operation method is ripe relatively.
Referring to Fig. 2, patent ductus arteriosus patient is in early days the time, its blood flow direction by ductus arteriosus be from descending aorta to pulmonary artery, late period, blood flow was two-way when pulmonary hypertension occurring.
Patent ductus arteriosus (infantile period) in early days can be treated by implantation surgery ligation, stopper or thromboembolism, respond well, if not treatment in early days, pulmonary hypertension often appears in adolescence or when adult, show as differential cyanosis, such end-stage patients still do not have good treatment way at present clinically.In case will move the conduit choke-out, the patient can be easy to occur acute right heart function depletion, threat to life.
Summary of the invention
The purpose of this utility model provides a kind of flap valve type overlay film frame, it is applicable to that the late arterial patent ductus merges the patient of pulmonary hypertension, miscellaneous function by support, pulmonary artery can be passed through to the blood flow of descending aorta, otherwise it is then not all right, support plays the effect of flap valve, reaches the effect of the treatment of eliminating left to right shunt.
For achieving the above object, this utility model is taked following design: a kind of flap valve type overlay film frame, it is made up of with making at the covering material layer of rack surface cylindric metal rack, it comprise first, second two parts, the first half is made up of cylindric metal rack and covering material layer of overlaying on its surface and growing down support; The latter half is made up of cylindric metal rack and the covering material layer that overlays on the surface; The covering material layer part that the first half grows places in the latter half metal rack, makes to have one section covering material layer that does not have metal rack up and down between the two-part metal rack.
Described the latter half metal rack is longer than the first half metal rack.
Described metal rack is a kind of stock support in rustless steel, the memorial alloy.Be woven to good by elastic metallic yarn.
The utility model has the advantages that: simple, convenient, practical, can treat the patients with terminal that patent ductus arteriosus merges pulmonary hypertension very effectively, improve this type of difficult disease rehabilitation of patients level.

The specific embodiment
As shown in Figure 1 and Figure 2, this utility model flap valve type overlay film frame is by cylindric metal rack with cover (can be to make) and form at the covering material layer of rack surface.
This utility model flap valve type overlay film frame comprise first, second two parts 1,2, the first half 1 is made up of cylindric metal rack 101 and covering material layer 102 of overlaying on its surface and growing support down; The latter half 2 is made up of cylindric metal rack 201 and the covering material layer 202 that overlays on the surface; The covering material layer part that the first half grows places in the latter half metal rack, makes to have one section covering material layer 1021 that does not have metal rack between the upper and lower two-part metal rack.
Described the latter half metal rack should be longer than the first half metal rack.The latter half metal rack and the first half metal rack length ratio were good with 3: 2.
A concrete embodiment can be as shown in Figure 1: the first half is made up of 2～4 joint metal racks and the long covering material layer of 4～6 joints, the latter half is made up of with making at the covering material layer on surface 3～4 joint metal racks, as shown in Figure 2, L1 is the overlay film length of the first half of support, and L2 is the overlay film length of the latter half of support.
The material of described upper and lower metal rack all is to be made by materials such as rustless steel or memorial alloys, and covering material is macromolecular material (as politef, polyester etc.) with good blood compatibility or polyester material etc.
The metal rack of upper and lower part of the present utility model is cylindric, can be formed by elastic metallic yarn braiding, and two parts are by a plurality of Z-shaped wire rings tubular construction that is in series up and down.
This utility model is to be used for the treatment of patent ductus arteriosus to merge patients with pulmonary hypertension.During use, there is one section covering material that does not have metal rack up and down in flap valve type overlay film frame between the two-part metal rack, descending aorta leads to Pulmonic blood flow to be sealed fully, and pulmonary artery can be from the outside (as A among Fig. 1) of the first half of support by the covering material part toward the blood flow of descending aorta, flow into the latter half the inside (as B place among Fig. 1) of support, pulmonary artery can be passed through to the blood flow of descending aorta, and it is unimpeded toward the blood flow of descending aorta to reach pulmonary artery; And the blood flow of descending aorta can only (as B place among Fig. 1) flow in overlay film frame, can not lead to pulmonary artery, reaches the effect that descending aorta cuts off to Pulmonic blood flow.Flap valve type overlay film frame of the present utility model can place in the bracket conveyer easily, by carrier support is sent to diseased region.
