Abstract

The invention discloses a transmission device for roller pin unlocking and a medical air supply device with the transmission device for roller pin unlocking. The transmission device for roller pin unlocking comprises a valve element, a roller pin, an isolating washer and an elastic component, wherein the isolating washer is arranged on the valve element in a sleeved mode and can slide along the outer circumferential wall of the valve element, an installation groove is formed in the isolating washer, the second end of the roller pin is arranged in the installation groove, and the roller pin is driven by the isolating washer to move in a roller pin sliding groove. Compared with a traditional medical air supply terminal roller pin unlocking device which is complicated in structure due to the fact that all parts need to be in linkage, the transmission device for roller pin unlocking has the advantages that the superposed force generated due to friction between all parts is effectively avoided, the roller pin can slide in the roller pin sliding groove more smoothly, and using is more convenient; in addition, the requirement for the manufacturing technology is relatively low, and manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of medical device preparation, and more specifically, to a transmission device for unlocking a needle roller and a medical air supply device having the same. Background technique [0002] At present, the German-style medical gas supply terminals and plugs on the market are mostly connected by double needle rollers. During the operation, it is necessary to press the first layer gasket to drive the rollers in contact with it to roll along the upper chute of the valve core, and then The upper needle roller group drives the isolation washer in contact with it to move downward, and the lower needle roller group in contact with the isolation washer rolls along the lower chute of the valve core, and then the lower needle roller group drives the lower washer to press down the spring. This state is an ideal state, and the following conditions must be met for the smooth implementation of this plan: 1. The symmetry of ...
