Abstract
Description
Technical Field
[0001] The invention relates to the technical field of reproductive medicine, and in particular to a constant temperature washing device for an embryo transfer catheter used in a reproductive center. Background Art
[0002] In vitro fertilization-embryo transfer is currently the main means of treating infertility. One of the most important steps is embryo transfer, which is the process of transferring the embryos obtained by in vitro fertilization culture back to the patient's uterine cavity. The disposable tool used for embryo transfer is called embryo transfer tube. At present, the embryo transfer tube is divided into two parts: the outer tube and the inner tube. First, the clinician inserts the outer tube of the embryo transfer tube through the cervical opening into the uterine cavity until the tube opening is close to the bottom of the uterus; at the same time, the technician in the embryo culture room sucks the embryo into the inner tube of the embryo transfer tube near the tube opening; inserts the inner tube with the sucked embryo into the outer tube cavity, and moves along the outer tube The tube enters the uterine cavity, and under B-ultrasound monitoring, the embryo is pushed into the uterine cavity; at the same time, the inner tube is withdrawn, and the microscope is used to check whether there are any embryo residues, whether the tube cavity is blocked, and whether the tube wall is stained with blood, etc., to evaluate whether the embryo transplantation is successful. Due to factors such as the shape and position of the uterus and the course of the cervical canal, the time required for each patient to insert the outer tube varies. In the case of patients with difficulty in transplantation, the time is even more immeasurable. Usually, before loading the embryo, laboratory technicians will use culture medium to fully rinse the inner tube to avoid jamming when loading the embryo, which may cause the embryo to remain in the transplant catheter after transplantation.
[0003] In the current rinsing process, insufficient rinsing will cause bubbles to appear in the tube when loading the embryo, resulting in the embryo getting stuck in the transfer catheter and causing the embryo to be retained in the transfer catheter after transplantation. In addition, the rinsing of the transfer tube is a manual operation, which cannot fully guarantee a sterile environment, and inevitably affects the rinsing quality.
