One-time bidirectional umbilical cord cutter

Abstract

The invention provides an improvement on a conventional one-time bidirectional umbilical cord cutter. The one-time bidirectional umbilical cord cutter comprises that: an upper shell is provided with a side semi-convex sphere for preventing upper and lower shells from being closed upon a slight external force; one end of a stop body is provided with a stop lever for preventing the umbilical cord from sliding out of an open end of an umbilical clamp; the inner side of a convex pin of the lower shell is provided with an upright semi-convex sphere which is occluded with a spherical groove on the bottom surface of a lower clamping arm and used for preventing the umbilical clamp from transversely slipping; the bottom of the lower shell is provided with a handle for firmly gripping the umbilical cord cutter; the head of an upper clamping arm is provided with a longitudinal flat hole into which hold-down sheets at the two ends of a cross bar of the upper shell are inserted, so that the upper clamping arm and the hold-down sheets are more firmly positioned and occluded; a clamping hook of the upper clamping arm is firmly occluded with a concave platform in the clamping arm groove of the lower clamping arm, so that the upper clamping arm and the lower clamping arm are more firmly closed; a blade is movably arranged on a blade fixing frame through two conjoined elastic split convex pins and is convenient to separate; and when the blade is disassembled, the umbilical cord cutter is completely made of plastic, so the cutter can be recycled as waste plastic.

Description

technical field [0001] The invention relates to an obstetrical medical device, in particular to a disposable bidirectional umbilical cord cutter. Background technique [0002] The invention patent 200910114909.9 applied by the inventor discloses a disposable umbilical cord cutting and umbilical protection device, which can realize the clamping, positioning, cutting, separation and protection of the umbilical cord; the operation process of delivery is simple, fast, safe and reliable, hygienic and sterile blood spattering The amount is small, and the chance of blood spattering, umbilical infection and harming the newborn is minimized, and good positive effects have been obtained; but it still has the following shortcomings: [0003] 1. The small end of the upper shell is only equipped with a limit block to limit the opening angle of the upper shell, but the upper and lower shells are easily closed by external force during transportation or before use, which is inconvenient to ...
