摘要:
A method of determining hypoxia in fetal scalp blood sampled during labour comprises the determination of total lactate dehydrogenase (LDH) in plasma obtained from the sample. The method can comprise the additional determination of K, Mg, Ca, AST, ALT, lactate in the plasma and/or blood. Increased values of one or more of LDH, Mg, Ca, AST, ALT, lactate are indicative of hypoxia in the fetus. Also disclosed is the use of a plasma separation apparatus in the method.

Methods are disclosed for non-invasively obtaining fetal cells from a pregnant female. The methods include placing an absorbent medium in an interlabial or intravaginal space or adjacent to the perineum at the vaginal opening of the pregnant female, and collecting vaginal fluid comprising cells in the absorbent medium while the absorbent medium is interlabial or intravaginal space or adjacent to the perineum at the vaginal opening. The absorbent medium is removed and cells are isolated from the absorbent medium to obtain the fetal cells. The fetal cells can be, for example, somatic cells, embroyic stem cells, fetal stem cells or trophoblast cells.

A sampling device for taking out a sample of a cell-containing liquid fluid, such as an amniotic fluid, from a human or an animal body comprises a syringe (10) with a fluid chamber and a sampling tube (29, 30). A volume of fluid may be drawn along a first path into the fluid chamber via the sampling tube and subsequently expelled from the fluid chamber along a second path. The device further comprises a valve device (14) having a first position, in which a cell filter (17) is included in one of said first and second paths, a second position in which the other of said paths is defined so as to by-pass the cell filter, and a third position, in which the fluid chamber is in communication with a removable fluid sample receptacle (27).

A device (1) is provided that is configured to indicate the presence or absence of one or more biological entities in a biological sample. The device comprises a sampling portion (11), the sampling portion comprising flexible material adjustably conformable to a part of a human or animal body, at least a portion of the sampling portion being absorbent and configured to receive a biological sample directly from the body; and a test portion (12) in fluid engagement with the sampling portion, the test portion comprising one or more test zones (14). The sampling portion and test portion are configured such that at least a portion of the sample received by the sampling portion is transferable to the test portion such as to contact one or more of the test zones, and wherein each test zone is configured to indicate the presence or absence of one or more biological entities in the sample.
摘要:
According to the present invention, an amniotic fluid collector is configured so as to be inserted and positioned inside the vagina of a birthing mother in order to collect amniotic fluid from the womb of the birthing mother. In particular, the amniotic fluid collector of the present invention comprises: a receiving member, in the side of which an opening is defined, which is inserted into the vagina of the birthing mother and which has a receptacle defined therein for receiving the amniotic fluid; and a positioning portion for positioning the receiving member inside the vagina. Thus, the effects of alleviating pain and psychological anxiety of a birthing mother and eliminating the danger of the occurrence of complications can be achieved, as well as those of easily and smoothly collecting amniotic fluid from the womb of the birthing mother.
