Description

TECHNICAL FIELD

[0001] The utility model relates to amniotic membrane cleaning support technical field especially relates to a simple support of cleaning amniotic membrane. BACKGROUND

[0002] Amnion is the innermost layer of placenta, a kind of semi-permeable membrane thin film, about 0.02-0.5mm thick, smooth, no blood vessels, nerves and lymph, with certain elasticity, about 0.02-0.5mm thick, amnion contains a large number of different collagens, and fibrous adhesion protein, laminin and other components, it is these components that make amnion can act as "transplantation basement membrane" and play a new healthy suitable matrix role.

[0003] Amnion wraps amniotic fluid and fetus, can prevent leukocyte infiltration, inhibit various proteases to reduce the degree of inflammation, inhibit inflammatory response, amnion has the function of inhibiting fibrosis and reducing scar formation.Amnion contains stem cells, which can be used for the treatment of various diseases after extraction and expansion. The various functions of amnion make it an excellent biomaterial in the field of regenerative medicine.

[0004] Whether amnion itself is directly applied or the cells in amnion are extracted and applied, the prerequisite is to clean the amnion torn from the placenta. The traditional method is to clamp one end or two sections with forceps and repeatedly shake in a dish containing cleaning solution, but the amnion torn from the placenta is generally an entire amnion, with a large area, about 300-400 square centimeters. Amnion is very thin and soft, and after being lifted with forceps, it becomes many wrinkles standing up or a bundle. The blood filaments and other substances attached to the amnion are difficult to clean and remove completely. As a biomaterial for disease treatment, the cleanliness and purity of amnion are required to be higher.

[0005] The prior art is either manually clamping amnion with forceps and repeatedly shaking in a dish, or repeatedly shaking and cleaning in multiple cleaning dishes. For larger amnion (such as more than 200 square centimeters), it is difficult to clean completely.

[0006] The amnion torn from the placenta will have bloodstains and other substances on the placenta, such as chorionic membrane and mucus, which will hide in the folds of the amnion. Or search for a patent of electric cleaning machine. Amnion is a biomaterial, and in order to be used later, the whole cleaning process needs to be carried out in a biological safety cabinet to maintain aseptic operation. The electric cleaning machine is not convenient to put in the safety cabinet. And before and after each cleaning, it also needs to be cleaned and disinfected, which is complicated. If cleaning and disinfection is not thorough, the amnion material will be contaminated.

[0007] The amniotic membrane cleaning support is simple and easy to operate, the overall support is made of stainless steel material and can be wiped and disinfected, the annular frame for fixing the amniotic membrane is made of smooth plastic material, can be produced in batches, is independently sterile packaged and used once, is beneficial to clean, is placed on the support for further washing, impurities are removed, and pure amniotic membrane is obtained, and the subsequent amniotic membrane cells are extracted from the amniotic membrane, qualified requirements are met, and the safety and effectiveness of application are laid as a foundation and guarantee.

[0039] The small ring 5 cooperates with the clamping groove 6 inside the large ring 4 and is used for supporting and fixing the amniotic membrane.

[0040] Referring to Figure 4 , Figure 8 In the present embodiment, the limiting strips 9 are fixedly installed on the inner walls of the two sides of the groove 8, the notches 14 are provided on the two sides of the protrusion 13, the limiting strips 9 are in sliding connection with the inner walls of the notches 14, the circular groove 16 is provided on the protrusion 13, and the support shaft 7 is rotatably installed with the circular groove 16 through a bearing.

[0041] Referring to Figure 8 In the present embodiment, the threaded hole 17 is provided on the outer side of the protrusion 13, the screw rod 18 is threadedly connected in the threaded hole 17, the handle 19 is fixedly installed at the outer end of the screw rod 18, and the screw rod 18 cooperates with the support shaft 7.

[0042] Referring to Figure 5 , Figure 6In the embodiment, the outer sides of the large ring 4 and the small ring 5 are arc-shaped, the diameter of the small ring 5 is 15 cm, the diameter of the large ring 4 is 15.2 cm, and the thickness of the large ring 4 is 1 cm.

[0043] In use, a plate is placed on the top of the base 1 to receive the liquid dripping from the washing to avoid contaminating the base 1 or the table top; the stainless steel support 2 is disinfected with alcohol, and a sterile container can be placed on the stainless steel base to receive the washing liquid. A sterilized double-ring frame is prepared. After the whole amniotic membrane is torn off, the small ring 5 is placed in a larger shallow plate, the amniotic membrane is laid on the small ring 5, and then the large ring 4 is sleeved with the small ring 5. The excess amniotic membrane at the edge is fixed on the circular frame of the large ring 4 frame with a sterile plastic clamp. At this time, the amniotic membrane is fixed on the double ring, and the large ring 4 and the small ring 5 are called a double ring when they are sleeved together. The double ring is connected through the two protrusions 13 and the two grooves 8. At this time, the amniotic membrane is flat and unfolded and vertically stands on the two stainless steel supports 2. At this time, the washing liquid is sucked by a pipette from top to bottom to wash the two sides of the amniotic membrane, wash off the bloodstains, and remove impurities. After cleaning, the amniotic membrane inside the ring frame is cut off with a blade for subsequent application. The handle 19 is rotated to drive the screw rod 18, the screw rod 18 is away from the support shaft 7 to release the locking of the support shaft 7, the double ring can be angle-adjusted, and then the angle of the amniotic membrane is adjusted to facilitate the cleaning of the amniotic membrane.
