Title:
CATHETER STRUCTURE, AND MEDICAL SUCTION DEVICE ON WHICH CATHETER STRUCTURE IS PROVIDED
Document Type and Number:
WIPO Patent Application WO/2024/080691
Kind Code:
A1
Abstract:
A catheter structure is disclosed. The present invention includes a first catheter, which has a first hardness value and has one end inserted into a respiratory organ of a patient, and a second catheter, which is joined to the other end of the first catheter and has a second hardness value that is greater than the first hardness value. According to the present invention, a catheter region inserted into a respiratory organ of the patient has relatively low rigidity such that the catheter can be smoothly inserted into and removed from a respiratory organ, 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 such that the driving force can be effectively transmitted to the insertion region. In addition, according to the present invention, surface friction resistance on the insertion region of the catheter is reduced such that the catheter can be smoothly inserted into and removed from the inside of a respiratory organ of the patient.
