Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a clinical navel blood infusion set of using of gynaecology and obstetrics, including infusion bag 1, infusion bag 1 is connected with infusion pipe 2 through filtering piece 4, the top of infusion pipe 2 is connected with intravenous syringe needle 3, introduce the navel blood into infusion pipe 2 through intravenous syringe needle 3, the top and the bottom of infusion pipe 2 are provided with governing valve 21 and governing valve two 22 respectively, be convenient for control infusion pipe 2 top and bottom communicate with close with the size of navel blood flow, the bottom of infusion pipe 2 just is located the top of governing valve two 22 and is provided with negative pressure tube 6, the tip of negative pressure tube 6 is provided with cylinder 7, change the inside pressure of infusion pipe 2 indirectly through the change of the inside atmospheric pressure of cylinder 7.
