The invention provides a mitral valve forming ring which comprises a ring body. The ring body is an enclosed ring body composed of a front ring section, a rear ring section, a left ring section and a right ring section integrally. A plurality soft sections and hard sections are arranged in the peripheral direction of the ring body at intervals, and the hard sections are located on the front ring sections and the rear ring sections of the ring body. Preferably, the mitral valve forming ring is a saddle-shaped forming ring. The mitral valve forming ring is simple, reasonable and compact in structure, overcomes the shortcomings in the prior art, can be applied to a mitral valve forming operation and can move coordinately with cardiac cycle while mitral valve leaflets are effectively closed.

The invention relates to a multifunctional medical urinal, which comprises a body, a suction cup and a top cover; a urination pipe is provided at the bottom of the urinal body; a urination switch is provided on the urination pipe; The bottom surface of the kettle body; the suction cup is in the shape of a truncated cone, and the large end surface is in contact with the ground; the suction cup is made of nitrile rubber; the kettle body is marked with a scale, and its scale range is 0-1000ml; The pot body is made of fluorescent materials; the edge of the top cover is provided with a fitting groove, and the fitting groove matches with the edge of the pot body to form a closed space with the pot body. Its advantages are as follows: it can ensure the safety of urination, monitor the urine volume, obtain accurate readings, and facilitate urination.

The invention discloses a manufacturing method of a sanitary product with a three-dimensional leak-proof enclosure, S1: a first coating device bends two left and right enclosures downward along the first coating position A to perform the first coating; S2 : Lay the absorbent main body on the first uncoated section b1 of the enclosure; S3: The third coating device bends the first uncoated section b1 upward along the third coating position C to perform the third clad. The three-dimensional leak-proof enclosure manufactured by the manufacturing method comprises an inner double-layer edge protection, an outer double-layer edge protection and a bending part. A sanitary product with a three-dimensional leak-proof guard, comprising the guard, the guard is arranged on the left and right sides of the absorbent main body in the sanitary product, and the absorbent main body includes leak-proof guards arranged sequentially from bottom to top. A backsheet, an absorbent core, and a liquid-permeable topsheet. Compared with the prior art, the invention has the advantages of good leakage prevention effect, comfortable wearing and the like.

The invention discloses a method for preparing a drug-loading aortic valve based on 3D printing and the drug-loading aortic valve, aiming at solving the technical problems of an existing valve replacement technique which requires anticoagulant therapy for a long time and is poor in durability. The method comprises the following steps: acquiring medical image data of the aortic valve; on the basis of the acquired medical image data of the aortic valve, establishing an aortic valve three-dimensional model; on the basis of the aortic valve three-dimensional model, forming a drug-loading aortic valve real body through 3D printing, wherein the drug-loading aortic valve real body comprises a valve ring real body and valve leaflet real bodies; forming drug-loading layers having drug-loading porous structures on the valve leaflet real bodies of the drug-loading aortic valve real body through 3D printing; and by virtue of a micro-droplet jetting technique, jetting anticoagulant drugs into the drug-loading porous structures of the drug-loading layers and jetting growth factors into the regions, except for the drug-loading porous structures, of the drug-loading layers, so as to form the drug-loading aortic valve. The printed aortic valve has a drug sustained-release function, the aortic valve is highly bionic and is capable of improving biocompatibility.
