Connector and suction catheter device having the same

Abstract

The present invention provides a joint and a suction catheter device with the joint. Whether operation of an operator is proper or not, water will never flow to the pipe side of a catheter when the suction catheter is cleaned. The joint is provide with an internal cylinder part for inserting into the suction catheter; an external cylinder part which is provided with a first end mouth connected with the pipe of the catheter, a second end mouth provided with the freely moved internal cylinder part, and a cleaning end mouth for supplying cleaning water; a valve plug part which is arranged inside the external cylinder part and is closer to the top end side than the cleaning end mouth, and the valve plug part is opened or closed through inserting the internal cylinder part, and the internal cylinder part is provided with a first protruding part which is used for pushing the valve plug part from the basal end side and enabling the valve plug part to open when the suction catheter is moved forward, a second protruding part which is used for pushing the valve plug part from the top end side and enabling the valve plug part to close when the suction catheter is retreated, and an opening part which is communicated with the cleaning end mouth when the second protruding part is abutted with the valve plug part.

Description

technical field [0001] The present invention relates to a connector and a suction catheter device having the same, which are used when connecting a suction catheter to a tracheal tube inserted into a patient's trachea. Background technique [0002] When a patient using an artificial respirator has a tracheal intubation tube or a tracheotomy tube (hereinafter collectively referred to as the tracheal tube) indwelling in the trachea, the foreign matter (sputum, etc.) trapped in the trachea cannot be voluntarily discharged out of the mouth. Therefore, generally, a suction catheter is inserted into a tracheal tube indwelling in the patient's trachea, and foreign matter (sputum, etc.) remaining in the trachea is sucked from the distal end of the suction catheter. In addition, in this specification, the device connected to the tracheal tube and used for inserting the suction catheter into the tracheal tube is referred to as "suction catheter device". [0003] For example, Patent D...

Problems solved by technology

[0007] However, in the suction catheter device described in Patent Document 1, when the operator does not operate properly, that is, for example, when the catheter is moved to the tracheal orifice side during cleaning of the catheter, the buckle is moved to the open position, or because When the catheter is not pulled back enough and the buckle cannot be fully moved to the closed position, there will be the following problems: the cleaning water leaks to the side of the trachea, and the cleaning water flows into the patient's body through the tracheal tube, causing pneumonia, suffocation, etc.
