The present invention relates to a catheter guide structure, and more particularly, to a catheter guide structure capable of freely adjusting an inflow direction and an inflow angle of a catheter to conform to a changed posture of a patient even when the posture of a patient is changed.

The medical suction unit is a medical foreign body suction device for forcibly sucking and removing foreign substances such as blood, saliva, vomit and secretion generated in the body of a patient while performing a procedure in a hospital.

In general, patients with mobility problems in hospitals or homes are usually equipped with a suction unit and guardians or nurses work to remove foreign objects from the airway or surgical site.

On the other hand, when foreign substances such as sputum are generated in the patient's respiratory apparatus having the oxygen respirator, the nurse removes the foreign substance by inserting the catheter provided in the medical suction unit into the patient's respirator while the oxygen respirator is installed in the patient .

In the case where the patient having the oxygen respirator is rotated or the direction in which the patient is lying, the nurse has to adjust the insertion direction and the angle of the catheter according to the changed posture of the patient, , Such an inconvenience is an obstacle to the smooth insertion of the catheter.

In addition, in the foreign substance inhalation treatment as described above, the nurse must normally shut off the catheter entry passage provided separately in the oxygen respirator. In order to suck foreign substances from the respiratory apparatus, the entry passage of the catheter must be temporarily opened. The medical staff must directly perform the interception and opening operation of the catheter entry path, and it is difficult to timely perform the inhaling treatment for the foreign body necessary for the patient due to the inefficiency of the treatment.

In addition, there has been a technical limitation that the catheter provided in the medical suction unit according to the prior art is mostly discarded after being used only once due to its difficulty in washing and management.

In addition, as described above, the catheter inserted into the patient's respiratory system must be exposed to contamination by the foreign substance during its use, and accordingly, the manager of the medical suction machine should periodically replace the catheter.

However, it takes a lot of time and effort to replace the catheter, and there is a problem that the coupling state of the catheter becomes poor during the process of coupling and installing the new catheter to the medical suction unit.

In addition, due to health problems such as infection due to foreign substances adhered to the catheter to be removed after use, special care must be taken in disposing of the catheter.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a catheter guide structure capable of freely adjusting an inflow direction and an inflow angle of a catheter so as to conform to a changed posture of a patient even when the posture of a patient is changed.

Preferably, the flow pipe 390 is installed between the oil tool 310 and the oxygen supply guide module.

Further, in the state where the oxygen supply guide module is fixed to the patient, the oil guide 310 is freely adjusted in the installation direction and the installation position by the fluidity of the flow pipe 390.

Further, a coil spring 395 through which the catheter moving into the oxygen supply guide module passes is provided on the inner wall surface of the flow pipe 390.

According to the present invention, even when the posture of the patient is changed, the inflow direction and the inflow angle of the catheter can be freely adjusted so as to match the changed posture of the patient.

In addition, according to the present invention, as the operation for inserting the catheter for sucking the foreign substance such as sputum present in the respiratory of the patient having the oxygen respirator into the respiratory of the patient and the operation efficiency in removing the catheter are secured, It is possible to perform nursing treatment quickly and efficiently.

In addition, according to the present invention, the catheter provided in the medical suction unit is easily cleaned and sterilized inside and outside.
