Problems solved by technology

[0002] Conventional intravenous infusion needle connectors generally do not have protruding wings, which is not convenient for medical staff to tighten the connector and infusion set connector during clinical use, and it is prone to leakage during infusion
Although there are a small number of products with protruding wings on the connecting seat, since the outer circumference diameter of the rear end of the connecting seat body is smaller than the outer circumference diameter of the seat body port, the mold design can only be demoulded by the side of the slider, and then axially drawn The way of core demoulding, the arrangement of accessories on the mold is a single row, the number of single injection molding accessories is small, and the production efficiency is low

Embodiment Construction

[0008] Below, illustrate the implementation of the present invention in conjunction with accompanying drawing:

[0009] When the extension width L of the wing (1) is not less than the radius R of the bottom (2) of the connecting seat body (4), the outer circumference diameter of the rear end of the seat body (3) is not less than the outer circumference diameter of the seat body port (5), The parting surface of the connecting seat is located between the widest extension of the wing (1) and the bottom (2) of the seat body (4), that is, between the A surface and the B surface, so that the plastic is axially demoulded after injection molding in the mold. Therefore, when the mold is made, it can be arranged in double rows or multiple rows, and the number of single injection molding parts is relatively large, so that it can be convenient for medical staff to tighten the connecting seat and the infusion set connector during clinical use. , and greatly improve the production efficienc...

Abstract

The invention relates to a connection seat with wings, which is matched with an intravenous infusion needle for an infusion set, and belongs to the technical field of medical devices. A wing-shaped infusion needle connection seat is characterized in that when the extension widths L of the wings are not less than the radius R of the bottom of a connection seat body, the external circumferential diameter of the rear end of the seat body is not less than the external circumferential diameter of the end opening of the seat body, and the parting surfaces of the connection seat are respectively positioned between the widest extension parts of the wings and the bottom of the seat, so the plastic is enabled to be moulded in a die in an injection manner and then be axially demoulded. Consequently, when the die is used for manufacturing, a double-line or multi-line accessory arrangement mode can be adopted, relatively more injection moulding accessories are produced at a single time, so the seat injection molding production efficiency is greatly improved.

Description

Technical field [0001] The invention relates to a winged connecting seat of an intravenous infusion needle for an infusion set, and belongs to the technical field of medical instruments. Background technique [0002] Conventional intravenous infusion needle connectors generally do not have protruding wings, which is inconvenient for medical staff to tighten the connector and infusion set connector during clinical use, and is prone to leakage during infusion. Although there are a small number of products with protruding wings on the connecting seat, since the outer circumference diameter of the rear end of the connecting seat body is smaller than the outer circumference diameter of the seat body port, the mold design can only be demoulded by the side of the slider, and then axially drawn The way of core demoulding, the arrangement of parts on the mold is a single row, the number of parts in a single injection molding is small, and the production efficiency is low.
