VENTILATING NEEDLE AND METHOD OF MANUFACTURING THE SAME |
摘要 |
This invention discloses a ventilating needle having a membrane-type filter stretched across the communication passage of a hub portion of the needle. In this invention, the membrane-type filter is of 2-ply type composed of a reinforcement layer and a water-repellent filter having a higher melting point than said reinforcement layer. This membrane-type filter is thermally adhered to a step portion formed in the inner wall of the hub portion through interfusion of the reinforcement layer and the step portion. This invention also discloses a method of assembling the ventilating needle in which a membrane-type filter is adhered to a step portion formed in the inner wall of the hub by means of ultrasonic waves. |
