Description

A menstrual blood collection and transfer device

technical field

The utility model relates to the technical field of transfer equipment, in particular to a menstrual blood collection and transfer device.

Background technique

Stem cells can treat various diseases such as immunity, injury and degenerative diseases, and the stem cell industry is currently booming. Adult mesenchymal stem cells can be derived from various tissues such as umbilical cord, placenta, cord blood, bone marrow, fat, and menstrual blood. Although umbilical cord, placenta, bone marrow, and fat are the main sources of clinical mesenchymal stem cells, most of them can only be treated with large-scale expanded allogeneic stem cells due to the limitation of materials (placental appendages or invasive materials). There are inevitably risks such as immune rejection and possible impact of unknown viruses. Fetuses can bank their own umbilical cord blood, but adults also have a great need for autologous stem cell banking. Bone marrow and fat have poor acceptance due to the invasive nature of their extraction. For women, the monthly and usually discarded menstrual blood is also a very rich source of stem cells, which can meet the needs of storing stem cells and expanding autologous stem cells on a large scale when needed in the future.

Menstrual blood stem cells have been applied clinically and are ideal seed cells for the treatment of various reproductive diseases, immune diseases, degenerative diseases, and injury diseases. Its safety and effectiveness have been verified by a number of in vivo and in vitro experiments. For example, a foreign team injected menstrual blood-derived mesenchymal stem cells into the ovaries of patients with poor ovarian response, which can significantly increase the fertilization rate of oocytes, embryo yield and clinical pregnancy rate; Zhejiang Hospital "uterine blood stem cells for mild Alzheimer's The project "Clinical Research on the Safety and Preliminary Effectiveness of Mutism" has passed the official filing of stem cell clinical trials. The above scientific research results have fully demonstrated the application potential and application value of menstrual blood stem cells.

Stem cells are abundant in menstrual blood and can be taken multiple times from the same donor. The steps of the method for separating and culturing menstrual blood stem cells mainly include: menstrual blood collection and transportation, laboratory density gradient centrifugation and adherent culture. Due to the different discharge rate of menstrual blood volume of each individual, menstrual blood collection requires at least 5-10ml of blood volume, and the more the better, it usually takes several hours of collection time, however, there is currently no device dedicated to collecting menstrual blood samples on the market available.

The donor lies on the gynecological examination bed, and the vagina and cervix are roughly disinfected with a large sterile cotton swab dipped in complex iodine, and then the vagina is opened with a dilator to expose the cervix and disinfected again. More complex iodine liquid. The medical staff opens the individual package and takes out the sterile menstrual blood collector 101, puts on sterile gloves, folds the opening 102 of the menstrual blood collector 101 to make it smaller, puts it deep into the vagina, and lets go so that the opening 102 surrounds the cervix as much as possible , and then remove the speculum. The donor can get up and move around, depending on the amount of blood, and return after 2-6 hours. The donor lies on the gynecological examination bed again, puts on the vaginal speculum again, and the vaginal speculum exposes the menstrual blood collector 101, and the medical staff sterilizes the grip part 103 with complex iodine, and then pulls the pull ring 109 to remove the top sheet 110, exposing the Sterile rubber inner cover 104 . After dipping the surface of the rubber inner cover 104 with a cotton swab, remove the needle cover 113, insert the needle 106 into the rubber inner cover 104, and use negative pressure to extract the blood in the menstrual blood collector 101 until it cannot be extracted. The menstrual blood collector 101 is taken out and discarded into a medical waste bin. After the blood is drawn, the needle 106 can be covered with the needle cover 113 and put into the storage box 111. The protrusion 112 can fix the needle 106, the syringe 108 and other parts of the menstrual blood transporter, so as to avoid the menstrual blood from overflowing during the transfer process. Finally, the storage box 111 can be placed in an incubator at 18° C. to 25° C. for storage, and then transported to the laboratory within 4 hours.

The above embodiments of the utility model have been described in detail in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned embodiments. Make various changes.
