AI Technical Summary

Technical Problem

Existing placental tissue collection bags are prone to damage and leakage, and antibacterial agents are easily oxidized, leading to bacterial contamination and reduced cell activity during the collection process, making it impossible to maintain the viability of placental tissue for a long time.

Method used

The placental tissue collection bag adopts a double-layer structure, combined with a one-way vent valve and an antioxidant sealing bag, which reduces the risk of leakage and slows down the oxidation rate. The antibacterial effect is improved by adding functional additives such as open-ring schisandrin, schisandrin and potassium sorbate to the contact layer.

Benefits of technology

It significantly reduces the risk of leakage, prolongs the preservation time of placental tissue, maintains cell viability, and improves antibacterial effect and safety, making it suitable for the collection and preservation of placental tissue.

Abstract

The invention relates to a placenta tissue collecting bag and application. The placenta tissue collecting bag comprises a protective layer, a one-way exhaust valve, a first sealing strip, a second sealing strip, an antioxidant bag and a contact layer. The collection bag is of a double-layer structure, the leakage risk can be remarkably reduced, biological safety protection is improved, the antioxidant sealing bag and the one-way exhaust valve are additionally arranged, the air content in the collection bag can be greatly reduced, and therefore the oxidation rate of placenta tissue is reduced, and cell activity is kept.
