CATHETER STRUCTURE, AND MEDICAL SUCTION DEVICE HAVING CATHETER STRUCTURE PROVIDED THEREON
Document Type and Number:
WIPO Patent Application WO/2023/043013
Kind Code:
A1
Abstract:
A catheter structure is disclosed. The present invention has a first catheter having a first hardness value and having one end inserted into respiratory organs of a patient, and a second catheter joined to the other end of the first catheter and having a second hardness value that is greater than the first hardness value. According to the present invention, a catheter region inserted into respiratory organs of the patient has relatively low rigidity so that the catheter can be smoothly inserted into and removed from respiratory organs, and a catheter driving region coupled to the insertion region so as to transmit driving force from a driving device to the insertion region has relatively high rigidity so that the driving force can be effectively transmitted to the insertion region. Furthermore, according to the present invention, surface friction resistance on the insertion region of the catheter is reduced so that same can be smoothly inserted into and removed from the inside of respiratory organs of the patient.
