5results about How to "Good hemostasis" patented technology

This invention belongs to the field of biomedical materials technology, specifically relating to an oxidized hyaluronic acid / carboxymethyl chitosan hemostatic sponge and its preparation method. The preparation method includes: oxidizing hyaluronic acid with sodium periodate to obtain oxidized hyaluronic acid; preparing aqueous solutions of oxidized hyaluronic acid and carboxymethyl chitosan; mixing the two solutions and forming a hydrogel through a Schiff base reaction between aldehyde and amino groups; cryogelatinizing the hydrogel at low temperature and then freeze-drying it under vacuum to obtain an expandable hemostatic sponge with a three-dimensional interconnected porous structure. Upon contact with blood, the sponge of this invention rapidly absorbs water and expands, increasing in volume by more than three times, forming a tight physical seal. Simultaneously, it adsorbs and activates platelets to accelerate coagulation, achieving highly efficient hemostasis. This sponge exhibits excellent biocompatibility, is completely degradable in vivo, and the preparation process is mild and requires no toxic cross-linking agents. It can be used for rapid hemostasis of deep, irregular, and non-compressible bleeding wounds.

The utility model relates to medical consumable technical field, and specifically discloses a sterile finger cots lamp on operating table, including lamp pearl shell body, one end of lamp pearl shell body is equipped with the lamp pearl, the other end of lamp pearl shell body is equipped with connecting piece, and connecting piece includes the connecting shell body fixed connection with lamp pearl shell body, and the front end of connecting shell body can be telescopic and is arranged, and the side of connecting shell body is equipped with magic band for being bound with the finger. The utility model can realize the flexible and various timely lighting operation of wearing on the finger, effectively shortens the operation time, and improves the work efficiency.

The utility model discloses a "O" vaseline gauze special for penis operation, including the long strip vaseline gauze, the middle part of vaseline gauze forms the long strip opening along vaseline gauze width direction extension, vaseline gauze top edge fixedly has the pad and presses the convex, and the pad and press the convex at the opening one side. After one end of vaseline gauze passes through the opening, the middle part forms the "O" type structure, and the pad and press the convex are at the "O" type structure. The utility model discloses good adhesion, and it is convenient to adjust the compression strength to the wound, and the hemostatic effect is remarkable, effectively reduces the discomfort of the patient when bandaging, and it is convenient to quick bandaging and replacement.

The present application provides a gelatin particle and a preparation method thereof, and a hemostatic fluid gelatin composition. The gelatin particle is a cross-linked gelatin particle, and the preparation raw material of the gelatin particle comprises gelatin and a high molecular material containing amino and / or carboxyl; the preparation process of the gelatin particle comprises the steps of forming a gelatin gel from the gelatin and crushing the gelatin gel, wherein the high molecular material is added to mix with the solution of the gelatin or the gelatin gel before or after the formation of the gelatin gel. The gelatin particle and the hemostatic fluid gelatin of the present application can quickly absorb the moisture in the blood after being applied to a bleeding wound, thereby increasing the concentration of red blood cells, blood coagulation factors and the like in the blood, accelerating the endogenous blood coagulation mechanism, and having a good hemostatic effect.

The application provides a hemostatic material and a preparation method thereof. The preparation raw material of the hemostatic material comprises gelatin and a natural polymer material, and the preparation process of the hemostatic material comprises the step of crushing gelatin gel in the presence of the natural polymer material; wherein the gelatin gel is obtained by gelation after cross-linking of the gelatin. The hemostatic material of the application comprises gelatin and a natural polymer material, and the gelatin gel is crushed in the presence of the natural polymer material, so that the particle size of the gel can be reduced, and finally the hemostatic material with good hemostatic effect is obtained.
