Problems solved by technology

[0008] By adopting the above-mentioned technical scheme, the circular convex column is inserted into the cervical canal, and the circular main body is absorbed and applied on the surface of the cervix. After 3-4 hours, it will form a gel state when it meets water, and it can be tightly applied on the surface of the cervix. The contact area between the postoperative wound surface of the cervix and the protruding structure and the tightness of the contact between the two can effectively improve the repair and anti-inflammatory effect on the postoperative wound surface, thereby shortening the healing time of cervical erosion and improving its healing effect

Embodiment 1

[0055] Embodiment 1: A biomedical repair membrane, which can be used for adjuvant treatment of cervicitis, cervical erosion and cervical cancer, including a membrane with a total height of 20±2mm. Such as figure 1 and figure 2 As shown, the diaphragm is molded through a mold (not shown) to form the following structure. The diaphragm includes a circular body 1 and a circular boss 2 fixedly connected to the upper surface of the round body 1, wherein the circular boss The height of 2 is 1 / 3-1 / 4 of the height of the entire diaphragm; at the same time, the interior of the circular boss 2 is hollow, and a circular through hole 3 is opened at the connection between the circular body 1 and the circular boss 2 . combine figure 2 and image 3 As shown, at this time, the medical staff aligns the diaphragm installed at one end of the holder (not shown) at the mouth of the cervical canal through a colposcope (not shown) under direct vision. Press the other end of the holder with you...

Embodiment 2-6

[0077] Embodiment 2-6: A biomedical repair membrane, the difference from Embodiment 1 lies in that its composition and proportion are different, as shown in Table 1 below.

[0078] The components of the parts by weight of embodiments 1-6 in a kind of biomedical repair film in table 1

[0080]

Embodiment 7

[0081] Embodiment 7: A biomedical repair membrane, the difference from Embodiment 1 is: in order to improve the compliance between the diaphragm and the cervical surface 7, as Figure 4 As shown, the above-mentioned protruding structure 4 is set as a 1 / 2 closed annular surface along the circumferential direction of the circular convex post 2, and at this time, 1 / 2 of the closed annular surface is attached to the postoperative wound surface 8. Therefore, not only can the repairing and antibacterial effects be ensured, but also resources can be saved, and when only one side has the postoperative wound surface 8, if one-half of the closed annular surface is used for drug administration, the The degree of compliance between the diaphragm and the cervical surface 7 helps to improve the stability of the diaphragm when it is applied to the cervical surface 7 .

Abstract

The invention discloses a biomedical repair film and a preparation method thereof, belonging to the technical field of medical materials, and its technical points include: a biomedical repair film, the diaphragm forms the following structure through a mold, which includes a circular main body and a fixed joint The round convex column on the upper surface of the circular main body is hollow inside, and there is a through hole at the connection between the circular main body and the circular convex column, and the connection between the upper surface of the circular main body and the circular convex column faces protruding outward, and a protruding structure is provided along the circumferential direction of the circular protruding post. The preparation method adopts stirring emulsification, film forming, freezing treatment, sublimation and drying. The invention is not only easy to operate, but also can ensure the content of available iodine, the biological activity and good biocompatibility of the diaphragm, so that the diaphragm can be released continuously and degraded naturally during use, which not only protects the cervical mucous membrane from the outside The invasion of viruses and microorganisms has given full play to the antibacterial and anti-inflammatory effects of the diaphragm, hemostasis and fluid absorption, protection of mucous membranes, and healing of wounds.

Description

technical field [0001] The invention belongs to the technical field of medical materials, and more specifically relates to a biomedical repair film and a preparation method thereof. Background technique [0002] Common methods for treating cervical erosion are mostly vaginal medication and physical methods. Traditional medication mainly includes effervescent tablets, suppositories, ointments, and lotions, etc., and most of them are traditional Chinese medicine or a mixed preparation of traditional Chinese medicine and antibiotics. Pain-relieving, blood-activating and muscle-promoting effects, and non-invasive, convenient medication, suitable for patients with mild cervical erosion (mild refers to the case where the area of ​​columnar epithelium eversion is less than 1 / 3 after being affected by estrogen). [0003] However, for moderate and severe cervical erosion (moderate refers to the case where the area of ​​columnar epithelium valgus is between 1 / 3 and 2 / 3 after being aff...
