Description

Storage of wet biological amnion is taken device

Technical Field

The utility model belongs to the biomedical field relates to medical instrument, especially a device is taken in storage of wet biological amnion.

Background

The amnion is located in the innermost layer of placenta, is smooth, has no blood vessels, nerves and lymph, has certain elasticity, is about 0.02-0.5mm thick, and consists of an epithelial layer, a basement membrane, a compact layer, a fibroblast layer and a sponge layer, wherein the basement membrane and the amniotic matrix layer of the amnion contain a large amount of different types of collagen and protein, and mainly comprise collagen types I, III, IV and V, fibronectin, laminin and the like.

The amnion as a novel biological material can be widely applied to the fields of ocular surface injury, body surface trauma, burn and scald, foot ulcer, nerve injury, tendon adhesion and the like. In the treatment of most diseases, the basal layer of the amnion needs to be pasted on an affected part when the amnion is used, the epithelial layer faces outwards, the basal layer and the epithelial layer of the amnion cannot be distinguished by naked eyes, the amnion is easy to be confused, and great inconvenience is brought to the operation of a doctor when the amnion is clinically used; meanwhile, when the amniotic membrane is used for treating body surface injury, the amniotic membrane in a wet state is difficult to completely spread and cover an affected part.

In order to distinguish the epithelial layer surface from the basal layer surface and facilitate taking, some products freeze-dry the amnion and then put the amnion into a filter paper support sheet, and make the basal surface of the amnion face upwards, and some products manufacture concave-convex surfaces for the amnion through a freeze-drying mould to distinguish the epithelial layer from the basal layer, thereby solving the problems to a certain extent. However, the structure of the amnion after freeze-drying is physically changed, the brittleness is increased, the toughness is poor, the amnion is easy to tear, most amnion needs to be rehydrated for use in practical clinical application, the whole process still needs to be finely controlled to be divided into an upper cortex layer and a lower basal layer, and the operation process is complicated.

The utility model provides a its technical problem take following technical scheme to realize:

the utility model provides a device is taken in storage of wet biological amnion, takes the accessory including the tissue save part and the tissue that can dismantle the assembly, wherein, tissue save part includes bottom tray and upper cover plate, and the upper cover plate can be dismantled to inlay and adorn in the bottom tray, the upper cover plate is fretwork fillet arris muscle structure, bottom tray equipartition is provided with the through-hole, the tissue take the accessory for have the roof of column gag lever post with the equipartition, wherein the rod footpath of unit column gag lever post is not more than the through-hole aperture on the bottom tray.

And the vertical distance between the upper surface of the bottom tray and the lower surface of the upper cover plate is 0.6 mm.

And a clamping groove and a buckle structure are arranged between the bottom tray and the upper cover plate.

The utility model has the advantages that:

1. the utility model discloses an upper cover plate is fretwork fillet arris muscle structure, and attached on the bottom tray down on the steerable amnion epithelium on the one hand, on the other hand can ensure that liquid gets into soaks the amnion, and the while can be more gentle control amnion be in the exhibition flat state all the time in this device and do not take place mechanical deformation.

2. The utility model discloses bottom tray design of punching guarantees that liquid gets into and can cooperate when soaking the amnion completely to take the accessory with the amnion complete ejecting, makes the stratum basale direct action attached in the operation surface of a wound, has effectively avoided doctor's tweezers to press from both sides the complicated operation of getting the exhibition flat transfer.

3. The utility model is provided with a clamping groove and a buckle structure between the bottom tray and the upper cover plate, controls the fillet rib to be positioned on the upper surface of the tiled amnion, and prevents the whole position deviation between the bottom tray and the upper cover plate,

4. the utility model discloses the vertical distance between bottom tray upper surface and the upper cover plate lower surface is 0.6mm, and this space is the actual storage space of amnion for the amnion is not destroyed and infiltration that can be abundant.

5. The utility model has the advantages of being scientific and reasonable in design, use through the cooperation that the accessory was taken to tissue save part and tissue, can conveniently effectively distinguish amnion epithelium layer and stratum basale, and take and use simple and conveniently, the operation is swift, weak point consuming time, can not influence the physics performance and the biological activity of stored material, the doctor distinguishes epithelium layer and stratum basale face when using more easily simultaneously, the work efficiency is improved, the influence that causes because of the used material is prevented, the improved generation product that numerous surgeons easily accepted, should obtain widelys using widely.
