L(FGF+ collagen)
It went through a special process to modify the surface of collagen and fibroblast growth factor (FGF). FGF, while exerting the sustained release and absorbability of collagen, takes collagen as the carrier, combines with its unique receptor, maintains ideal concentration and activity around damaged tissues, and cooperates with normal cell differentiation, thus achieving unique therapeutic effect, maximizing its biological efficacy and overcoming the disadvantages of single use. L 1, actively repair and restore the healed tissue function; FGF promotes active wound repair by promoting the rapid proliferation of cells related to wound repair.
L2。 Improve the quality of healing and reduce scar formation; Shorten wound healing time and accelerate wound healing.
L3。 Good hemostatic effect: after contact with blood, it can induce platelet aggregation, stimulate platelet to release coagulation factors, activate prothrombin, promote the formation of blood clots, attach to the oozing wound, form a gel layer on the wound, block the injured blood vessels and achieve the purpose of hemostasis more effectively.
L4。 Neurotrophic effect: FGF, like nerve growth factor (NGF), can maintain the survival and promote the growth of neurons in many brain regions, including the frontal parietal lobe and occipital lobe.
Cortex; Striatum and septa. FGF is the mitogen of glial cells such as axonal glial cells, astrocytes and Schwann cells, and FGF has neurotrophic effect in vivo.
5. Low antigenicity; Because there are no tryptophan residues and few tyrosine residues, it is prepared by enzyme digestion technology and cobalt 60 sterilization technology, with high purity, weak antigenicity and good biocompatibility.
● Biodegradability: it can be hydrolyzed into amino acids and absorbed by human body;
● ⒎ Exclusive use of the technology of the national invention patent "Sponge material for promoting the healing of spinal cord injury and its preparation method and application", and the intellectual property rights are protected by the state for 20 years; L[ scope of application]
L 1, old injuries: l diabetic ulcer, radiation ulcer, bedsore, fistula, mucosal ulcer and erosion.
L2。 Burn and frostbite wounds.
L3。 Fresh wound: L wound includes mechanical injury of soft tissue; Sharp instrument injury; Laser wounds, wounds after medical beauty; Filling of residual cavity and stump in surgical wound and parenchymal organ operation; Around the anastomosis of hollow organs; Nerve injury; Wounds with bone, cartilage and tendon injuries. L[ usage]:
First, the general usage:
Be sure to dry; And put it in the needed position at a time.
L 2。 Special usage:
L 1, old injury:
L Routine debridement, removing necrotic and inactive tissues, secretions and exudates, removing pathological granulation tissue and cutting off fistula scar tissue. Treat active bleeding, make the wound fresh, and complete the operation with routine usage. According to the seepage situation, 1-3D repeats the above operation again. Until the wound heals.
L2。 Burn and frostbite wounds:
L Routine debridement, removing necrotic and inactivated tissues, secretions and exudates, and removing pathological granulation tissue. After routine use, the sterile dressing is slightly pressurized and bandaged.
L3, General Surgery:
L4, orthopedics:
After repairing and reconstructing lA, muscles, tendons, major blood vessels and nerves, Chuangbifu was applied annularly to tendons, blood vessels and nerves and inside the sheath. Promote tissue healing, prevent or reduce adhesion and scar hyperplasia.
Pounds. After the periosteum was repaired as much as possible by internal fixation of fracture, Chuangbifu was applied in the outer ring of broken periosteum according to the conventional method. Cartilage injury or defect, including articular cartilage, is usually applied to its surface. Promote fracture healing and prevent nonunion and delayed healing.
LC, artificial joint replacement and wound healing are applied to the contact surface between prosthesis and bone to accelerate biological internal fixation.
Limited in spinal surgery, Chuangbifu is used for spinal epidural sac and residual cavity after discectomy. Include intervertebral disc disease, spinal stenosis and decompression of spinal trauma. Promote the healing of various tissues, including the recovery of nerves, and prevent postoperative adhesion.
L5, urology:
Conventional packaging of prostatic fossa after prostatectomy.
Repair of hypospadias and urethral injury. The conventional usage of Chuangbifu is used to repair urethra (conventional indwelling catheter).
L6, Neurosurgery:
After the surgical focus such as intracranial hematoma was cleared and the bleeding was stopped routinely, Chuangbifu was used instead of gelatin sponge in the conventional way to treat the large area bleeding wound.
L7, otolaryngology:
L turbinate hypertrophy, chronic sinusitis, tonsillectomy, etc. Chuangbifu is suitable for surgical excision of wounds.
L8, obstetrics and gynecology:
Pounds. Hysterectomy (including vaginal hysterectomy). After the stump is closed, the wound must be attached to the stump by conventional methods. L 1, should be thoroughly debrided before use to control infection.
L2。 This product should be used under aseptic conditions.
L3。 This product cannot be used with ointment antibiotics, alcohol and iodine. (mainly caused by FGF)
L4。 This product is sterilized by cobalt 60 and used once. It is forbidden to use the damaged package.
L5。 If you are allergic to this product, stop using it. If you are allergic, stop using it. (mainly caused by FGF) L Chuangbifu (50mm×50mm×3mm) contains active ingredient 12000 units (measured by NH3T3 cells); (The so-called bioactive substances refer to trace or small amounts of substances that originate from organisms and have an impact on life phenomena. )
L moisture < 3%;
