Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly, to a kind of novel meiofauna uterine perfusion device.
Background technique
According to experiment needs, especially in the research of field of reproduction, need to simulate on animal clinically using drug into
The method of row uterine cavity perfusion or the model that building disease is perfused by uterine cavity, and then carry out relative mechanism and grind
Study carefully.As currently used experimental animal, rodent uterine cavity is narrow, and cervix opening diameter is small, double for single vagina uterus duplex
Uterine neck there is no the effectively easy method and device for simulating clinically intrauterine perfusion at present in the research of above-mentioned basal animal, related
Experiment need to prick uterus locally injecting after the cornua uteri of distal end using fu jie is opened, and similar approach fails to simulate clinically uterine perfusion completely
Method, local injection of uterus damage endometrium and muscle layer, postoperative uterus local lump, infection and abdominal cavity adhesion rate compared with
Height even results in mortality of animals raising, and the disturbing factor of scientific research increases, and finally reduces experimental reliability.
In presently relevant research frequently with through abdomen puncture mesometrium toward uterine cavity injection of medicine, this method have it is following not
Foot: 1. are formed directly into mesometrium injection uterine cavity, fail the method for reproduction of reality clinically uterus intrauterine perfusion, use this method
It carries out modeling and therapeutic effect is unreliable.2. injecting from uterine cavity, medical fluid can flow to vagina, and ligation distal end uterus is needed before injection
Chamber increases the damage of uterus and peripheral vascular tissue, postoperative to may occur in which local hemorrhage, oedema, infection and Asherman's syndrom, intervenes
Experiment effect.3. injecting mesometrium through abdomen, medical fluid can be oozed out from injection point, increase the loss of drug, while medical fluid extravasation increases
Add the probability of adhesion and the pollution of abdominal viscera.Therefore, a kind of device for being effectively used for uterine perfusion need to be developed.
Summary of the invention
Regarding the issue above, the present invention provides a kind of novel meiofauna uterine perfusion device, the device
