Umbilical cord blood stem cell storage and recovery device high in automation degree

Abstract

The invention discloses an umbilical cord blood stem cell storage and recovery device high in automation degree. The umbilical cord blood stem cell storage and recovery device high in automation degree comprises a storage tank. The storage tank is internally provided with a rotating shaft. The upper end of the rotating shaft penetrates the storage tank and is exposed to the upper end of the storage tank. The upper surface, corresponding to the upper end of the rotating shaft, of the storage tank is provided with a drive device. The upper end and the lower end of the side face of the rotating shaft are rotationally connected with the storage tank through bearings. The side face of the rotating shaft is provided with a storage device. A fixing frame of the storage device is fixedly connectedwith the rotating shaft. The left end of the upper surface of the storage tank is provided with a recovery device. The lower end of the side face of the storage tank is provided with a conveying device. According to the umbilical cord blood stem cell storage and recovery device high in automation degree, umbilical cord blood stem cells can be stored in a classified manner, gasified liquid nitrogen can also be recovered, resources are saved, the temperature and the air pressure in the storage tank can be detected, automatic conveying of the liquid nitrogen is facilitated, the automation degreeis high, operation is easy, and using is convenient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a storage and recovery device for umbilical cord blood stem cells with a high degree of automation. Background technique [0002] The collection of umbilical cord blood is after the newborn is born. Take the baby’s 3-8cm umbilical cord and store it with two hemostats to ligate and cut off the umbilical cord. Blood and umbilical cord blood collection is different from traditional bone marrow collection. It does not require anesthesia. It is painless and has no side effects. The placenta and umbilical cord were originally thrown away as waste after the fetus was born. It is carried out after complete separation, so there is no adverse effect on mother and child. It belongs to "waste utilization, turning waste into treasure". Umbilical cord blood contains a large number of stem cells, called umbilical cord stem cells, and stem cells are actually the main cells of the human b...

[0002] The collection of umbilical cord blood is after the newborn is born. Take the baby’s 3-8cm umbilical cord and store two hemostats to ligate and cut off the umbilical cord.

The placenta and umbilical cord were originally thrown away as waste after the fetus was born. It is carried out after complete separation, so there is no adverse effect on mother and child. It belongs to "waste utilization, turning waste into treasure". Umbilical cord blood contains a large number of stem cells, called umbilical cord stem cells, and stem cells are actually the main cells of the human body. It can be said that the human body is composed of stem cells. In existing medicine, cord blood stem cells are usually tested and preserved. The existing preservation method is usually to directly use liquid nitrogen for cooling and preservation, which has a low degree of automation and cannot control the preservation environment. detection, inconvenient to use
