Ring crush electrocardiogram chest lead connector

Abstract

The invention relates to a medical facility, in particular to a ring crush electrocardiogram chest lead connector which is composed of a negative pressure sac, an electrode ring, a hand pressure barrel, a ring groove barrel, a rubber ring and liquid outlet pores. The ring groove barrel is a cylinder body provided with a ring groove with an opening upward, the bottom of the ring groove barrel is uniformly distributed with the liquid outlet pores around the periphery. The hand pressure barrel is a cylinder body with cross section being of T shape, and the lower end of the hand pressure barrel is positioned in the ring groove of the ring groove barrel. The electrode ring is of an upside down funnel shape, and the bottom of the electrode ring is integrated with the inner wall of the ring groove barrel. The invention adopts the push and press of a ring shaped piston, ensures enough pressure to lead electrode liquid out, and achieves the effect of uniform smearing.

Description

technical field [0001] The invention relates to a medical device, in particular to a ring pressure electrocardiogram chest lead connector. Background technique [0002] Patent No. 200820025684.0's invention "Conductive Liquid Self-Applying Electrocardiogram Chest Lead Electrode" discloses a solution to smear the conductive liquid by passing the liquid in the conductive liquid storage tube through the ring-shaped liquid application tube. This solution has the following defects: [0003] 1. Since one end of the conductive liquid storage tube is open and the other end is closed, it is difficult for air to enter the tube, and it is difficult for the conductive liquid to flow out under its gravity without other pressure applied. [0004] 2. Since the lower end of the conductive liquid inflow conduit communicates with a certain point on the circumference of the annular coating tube, this makes it impossible for the conductive fluid to flow from multiple points on the circumference...

[0004] 2. Since the lower end of the conductive liquid inflow conduit communicates with a certain point on the circumference of the annular coating tube, this makes it impossible for the conductive fluid to flow from multiple points on the circumference of the annular coating tube at the same flow rate before it is completely filled with the circular coating tube. Outflow from the hole, so it is difficult to achieve the purpose of uniform application
