A medical venous infusion tube surface cut-off communication device

Abstract

The invention discloses a medical intravenous infusion pipe surface truncation communicating device. Two groups of pipelines can be communicated with each other in a wall breaking mode via the medicalintravenous infusion pipe surface truncation communicating device which is a truncation-free communicating device. The medical intravenous infusion pipe surface truncation communicating device is characterized by comprising two groups of annular fixing supports, a group of middle communicating pipes and two groups of auxiliary communicating pipes; the two groups of annular fixing supports are parallelly arranged, the middles of the two groups of annular fixing supports are communicated with each other via the middle communicating pipes, two ends of each group of annular fixing supports are correspondingly communicated with two ends of the other group of annular fixing supports via the auxiliary communicating pipes, two arc-shaped support arms are parallelly arranged at two ends of a connecting plate, a circle of sealing adhesive tape is arranged at the edge of the inner side surface of each of the two arc-shaped support arms and the connecting plate, one end of each arc-shaped supportarm is arranged on a buckle, a hinge frame is arranged at the other end of each arc-shaped support arm, one end of each arc-shaped fixing arm is correspondingly hinged onto the corresponding hinge frame, integral circles are formed by the two arc-shaped fixing arms and the corresponding arc-shaped support arms, a groove is formed in the other end of each arc-shaped fixing arm, the grooves are inone-to-one correspondence to the buckles, and a plurality of wall breaking rods are arranged on inner circles of the arc-shaped fixing arms and the arc-shaped support arms.

Description

technical field [0001] The invention relates to a device for cutting and connecting the surfaces of medical intravenous infusion tubes, which relates to a connecting device for preventing two groups of pipelines from being cut off during the use of medical pipelines, and belongs to the field of medical facilities. In particular, it relates to a disconnection-free communication device that connects two sets of pipelines in a wall-breaking manner. Background technique [0002] At present, in the medical process, the intravenous infusion tubes are all flexible tubes, and the material is mostly plastic. For example, adding new drug components during infusion, etc., the existing pipeline confluence or diversion in the medical process uses a three-way tube, cuts off the existing pipeline, and then connects the three-way tube to achieve confluence Or shunt, the connection work was carried out before use, and for unforeseen emergencies during use, it is not applicable to merge the ...
