Problems solved by technology

The difficulty of this operation is that the wall of the umbilical vein is usually in a collapsed state. There is no other assistance when the cannula is inserted into the umbilical vein. If there is a slight deviation, the end of the cannula will squeeze the umbilical vein to cause further collapse. Inability to insert, so often multiple maneuvers are required to insert the cannula into the umbilical vein

Embodiment Construction

[0042] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] In each embodiment of the present invention, orientation words such as vertical, horizontal, left, right, top, bottom, etc. are based on the convenience of description, and are the orientation relationships of various structures provided by the present invention such as shrapnel in a specific form, not for any The positional limitation in the state, let alone the absolute limitation of the claim. More specifically, it means that the shrapnel provided by the present invention has two arms of different lengths. When the longer one of the two arms is placed vertically or substantially vertically, the shorter end is horizontal or substantially horizontal. Vertical, horizontal, left, right, top, and bottom are only for this positional relations...

Abstract

The present invention provides a dilator for umbilical vein puncture. The dilator for the umbilical vein puncture comprises a hand-held portion and a first extension member, one end of the first extension member is a first insertion section for inserting an umbilical vein, the other end of the first extension member is connected with the hand-held portion, and the first insertion section is a structure with a radial-direction size gradually increased from an end portion away from the hand-held portion to a direction connected with the hand-held portion; and a first insertion groove is arrangedin the first insertion section and used for insertion of an intubation tube for the umbilical vein. In the provided dilator for the umbilical vein puncture, the end portion of the insertion section is relatively small and convenient for insertion into the umbilical vein, then the structure with the gradually increased radial-direction size opens the umbilical vein, and then the intubation tube isinserted into the umbilical vein along the first insertion groove, thereby greatly facilitating the operation of the insertion of the intubation tube into the umbilical vein, reducing operation difficulty of operations and saving time.

Description

technical field [0001] The invention relates to a medical device, in particular to a dilator for umbilical vein puncture. Background technique [0002] Since the 1980s, umbilical vein cannulation has been one of the best ways to resuscitate newborns with asphyxia. The umbilical vein has the advantages of large lumen and high success rate of operation methods. Infants with low birth weight are infused with drugs, nutrient solutions, blood products, etc. [0003] In the prior art, when the umbilical vein is intubated, the edge of the reserved umbilical cord is lifted by two hemostatic forceps or sterile forceps to expose the umbilical vein and umbilical artery, and then the cannula is clamped by an elbow fine forceps, or the cannula is held by hand , insert the cannula into the umbilical vein with gentle and slow rotations. The difficulty of this operation is that the wall of the umbilical vein is usually in a collapsed state. There is no other assistance when the cannula is...
