Abstract
A nozzle, a coating device, and a coating method are able to selectively and easily apply a coating liquid to desired portion of a medical elongated body. The nozzle includes a nozzle distal portion that is provided with a holding space in which a coating liquid to be applied to a shaft can be held, and a nozzle main body portion that is provided with a lumen through which the coating liquid is delivered to the nozzle distal portion, and an opening portion via which the lumen and the holding space communicate with each other.
Claims20
A nozzle comprising:
- a nozzle distal portion including a holding space to hold a coating liquid to be applied to a medical elongated body;
- a nozzle main body portion that possesses a distal end, the nozzle distal portion being located at the distal end of the nozzle main body, the nozzle main body portion including a lumen through which the coating liquid is delivered to the nozzle distal portion;
- and
- the nozzle main body including an opening via which the lumen and the holding space communicate with each other so that the coating liquid delivered through the lumen passes through the opening and enters the holding space.
A coating device for coating a medical elongated body comprising:
- a nozzle comprised of a nozzle main body portion and a nozzle distal portion, the nozzle main body portion possessing a distal end at which is located the nozzle distal portion, the nozzle distal portion being located at the distal end of the nozzle main body, the nozzle distal portion including a holding space to hold a coating liquid to be applied to the medical elongated body that extends in an axial direction, the nozzle main body portion including a lumen through which the coating liquid is delivered to the nozzle distal portion, and the nozzle main body including an opening portion that communicates with the lumen and opens into the holding space;
- a movement mechanism that controls movement of the nozzle and/or the medical elongated body so that the coating liquid is applied to an axial portion of the medical elongated body by relatively moving, in a state where a part of the medical elongated body is disposed in the holding space, the nozzle and the medical elongated body along the axial direction of the medical elongated body.
A method of applying a coating liquid to a medical elongated body having an axial extent and extending in an axial direction, the coating method comprising:
- applying the coating liquid to a portion of the axial extent of the medical elongated body by relatively moving, in a state where the medical elongated body is brought into contact with the coating liquid held in a nozzle distal portion that is included in a nozzle, the nozzle and the medical elongated body along the axial direction of the medical elongated body.
