Stem cell extraction device

Abstract

The invention discloses a stem cell extraction device. The device comprises a thermal insulation pipe, wherein the insulation pipe is internally provided with a collection cavity which runs through from top to bottom; a sealed collection device capable of collecting blood is fixedly connected in the collection cavity. According to the device, a needle part for collecting the blood is isolated fromthe contact with outside air, so that the blood is prevented from being contaminated so as to influence stem cells in the blood; cavity communication in the needle part realizes a function similar tothat of a one-way valve, and blood samples are collected in a relatively safe and clean environment; in addition, pushing power conversion is used at a needle puncturing part to perform uniform smearing of medicament on epidermis for disinfection and sterilization; when a needle puncturing point is chosen, the distribution of blood vessels can be exposed by ultraviolet radiation; accurate sampling is achieved; equipment waste is avoided; the temperature of a temporary storage space can be controlled for guaranteeing the activity of the stem cells in the blood.

Description

technical field [0001] The invention relates to the technical field of cell extraction, in particular to a stem cell extraction device. Background technique [0002] At present, due to the plasticity of stem cells, various stem cells are often extracted for pairing work, so as to cultivate and maintain various tissue cells of the human body, which are often used to treat medical miscellaneous diseases such as blood system diseases and tissue and organ transplantation. During the stem cell extraction process, a stem cell sampling device is often required to extract blood from the human body, and then further separate the plasma from the stem cells. Exposure to an environment higher than 4 degrees Celsius for a long time is not conducive to the maintenance of cell activity, which in turn affects the subsequent separation and culture process, and the needle for extracting plasma will be contaminated by air contact before entering the skin. At the same time, the needle point Th...
