The invention comprises the following steps: a 1 st conduit having a 1 st durometer value and having one end inserted inside the respiratory system of the patient; and a 2 nd catheter coupled to the other end of the 1 st catheter and having a 2 nd hardness value greater than the 1 st hardness value. According to the present invention, the insertion region inserted into the respiratory system of the patient has low rigidity, so that the catheter can be smoothly inserted into and taken out from the respiratory system, and the driving region in the catheter combined with the insertion region and transmitting the driving force from the driving device to the insertion region has high rigidity, so that the driving force can be effectively transmitted to the insertion region. Meanwhile, according to the present invention, as the surface frictional resistance of the catheterization region is reduced, the catheter can be more smoothly inserted into and withdrawn from the inside of the respiratory system of the patient.
Description
Technical Field
The present invention relates to a catheter structure and a medical aspirator provided with the catheter structure, and more particularly, to a catheter structure having a low rigidity in an insertion region of a catheter into a respiratory system of a patient, capable of smoothly inserting and removing the catheter into and from the respiratory system, and having a high rigidity in a driving region of the catheter coupled to the insertion region and transmitting a driving force from a driving device to the insertion region, so that not only can the driving force be effectively transmitted to the insertion region, but also the catheter can be more smoothly inserted into and removed from the respiratory system of the patient with a decrease in frictional resistance on a surface of the insertion region of the catheter.
Background
The medical aspirator is a medical foreign matter inhaling device which forcibly inhales foreign matters such as blood, saliva, vomit and secretion generated in a patient into a container and removes the foreign matters during a hospital operation.
Generally, in hospitals or at home, patients with impaired mobility wear such medical aspirators, and a guardian or a nurse takes charge of removing foreign substances from airways or operation sites.
On the other hand, if a foreign matter such as sputum is generated in the respiratory system (respiratory organs) of a patient wearing the oxygen respirator, the nurse inserts a catheter provided in the medical aspirator into the respiratory system of the patient in a state where the patient wears the oxygen respirator, thereby removing the foreign matter.
Such a catheter is divided into an insertion region, which is a portion inserted into the respiratory system of a patient, and a driving region, which is a portion extending from the insertion region and transmitting a driving force of the catheter from the catheter advancing and retreating driving device to the insertion region.
On the one hand, the insertion region of the catheter needs to have low rigidity in order to be smoothly inserted into the inside of the respiratory system of the patient, and the driving region needs to have high rigidity in order to effectively transmit the driving force to the insertion region, however, the catheter according to the related art is integrally manufactured with materials having the same rigidity.
Meanwhile, although the outer surface of the insertion region of the catheter should have low frictional resistance to be smoothly inserted into the inside of the respiratory system of the patient, the catheter according to the related art has technical limitations in that the function and structure of reducing frictional resistance are not adopted.

Preferably, the surface of the 1 st conduit is treated with a lubricious coating.
Furthermore, it is characterized in that the outer surface of the 1 st catheter is provided with at least one protruding rail in the deployment direction of the 1 st catheter.
In one aspect, a catheter structure according to the present invention includes: a catheter inserted into the respiratory system of the patient to inhale the foreign matter; and at least one protruding rail arranged on the outer surface of the catheter along the unfolding direction of the catheter.
Effects of the invention
According to the present invention, the insertion region inserted inside the respiratory system of the patient in the catheter has low rigidity, so that the catheter can be smoothly inserted into and taken out from the respiratory system, and the driving region in the catheter combined with the insertion region and transmitting the driving force from the driving device to the insertion region has high rigidity, so that the driving force can be effectively transmitted to the insertion region.
Meanwhile, according to the present invention, as the surface friction resistance of the insertion region of the catheter decreases, the catheter can be more smoothly inserted into and taken out from the inside of the respiratory system of the patient.

Detailed Description
Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. It should be noted that like parts in the figures are denoted by like reference numerals as much as possible. Further, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.
Fig. 1 is a block diagram of a catheter structure according to one embodiment of the invention. Referring to fig. 1, a catheter structure 100 according to an embodiment of the present invention includes a 1 st catheter 110 and a 2 nd catheter 120.
The 1 st conduit 110 forms an insertion region, which is a portion inserted inside the respiratory system of the patient, and the 2 nd conduit 120 forms a driving region transmitting a driving force transmitted from a driving device (not shown) for driving the conduit structure 100 forward or backward to the 1 st conduit 110.
Specifically, one end of the 1 st conduit 110, which is formed with a suction port for sucking foreign substances such as sputum, is inserted into the respiratory system of the patient, and one end of the 2 nd conduit 120 is coupled to the other end of the 1 st conduit 110, and the other end of the 2 nd conduit 120 is connected to the driving device.
In practicing the present invention, it is preferable that the hardness value of the material constituting the 2 nd conduit 120 (e.g., PVC) is formed to be greater than the hardness value of the material constituting the 1 st conduit 110, so that the 2 nd conduit 120 can effectively transmit the driving force from the driving means to the 1 st conduit 110 with reinforcing the rigidity of the 2 nd conduit 120, while the 1 st conduit 110 has a relatively flexible structure so as to be more flexibly deformed according to the curve inside the respiratory system when entering the inside of the respiratory system of the patient.
Fig. 2 is a process flow diagram of a manufacturing process of a catheter structure according to one embodiment of the invention. Hereinafter, a manufacturing process of the catheter structure 100 according to an embodiment of the present invention will be described with reference to fig. 2.
First, a manufacturer manufactures the 1 st catheter 110 by injecting a PVC material having a hardness value of 80 (unit: shore D), and manufactures the 2 nd catheter by injecting a PVC material having a hardness value of 90 (unit: shore D), and then bonds the ends of the 1 st catheter 110 and the 2 nd catheter 120 manufactured in this way, respectively, by being arranged to butt against each other (S210).
Then, the manufacturer joins the mutually joined ends of the 1 st and 2 nd conduits 110 and 120 by various joining methods such as ultrasonic fusion to form the joint 130, thereby realizing a continuous communication structure between the 1 st and 2 nd conduits 110 and 120 (S230).
In the practice of the present invention, various methods such as a fusion method using a high frequency and a bonding method using an adhesive may be employed in addition to the ultrasonic fusion method when joining the mutually joined ends of the 1 st catheter 110 and the 2 nd catheter 120.
In one aspect, in practicing the present invention, the manufacturer performs a lubricious coating (e.g., a teflon coating) treatment as shown in fig. 3 on the outer surfaces of the 1 st and 2 nd catheters 110 and 120, so that the coefficient of friction on the surface of the catheter structure 100 can also be minimized (S250).
In one aspect, in practicing the present invention, the manufacturer may also apply a lubricious coating to only the outer surface of catheter 1 110 as part of the insertion into the patient's respiratory system.
Further, in practicing the present invention, the manufacturer can increase the rigidity of the catheter structure 100 by heat-treating the surface of the lubricating coating with a heat-curing device after the lubricating coating treatment in the aforementioned step (S250) (S270).
Fig. 4 is a view showing a cross-sectional structure of a catheter structure according to another embodiment of the present invention. Referring to fig. 4, on an outer surface (outer side) of the catheter structure 100 according to another embodiment of the present invention, a protruding rail 150 is continuously formed in the deployment direction of the catheter structure 100.
In practicing the present invention, a plurality of such rails 150 are preferably formed in parallel at prescribed intervals along the cylindrical outer surface of the catheter structure 100.
As described above, since the protruding rail 150 formed on the outer surface of the catheter structure 100 makes line contact with the tissue inside the respiratory system of the patient during the forward and backward movement of the catheter structure 100 inside the respiratory system of the patient, the contact area of the catheter structure 100 inside the respiratory system of the patient can be minimized, and as a result, the frictional resistance of the catheter structure 100 inside the body can be minimized.
As described above, in the present invention, frictional resistance during movement of the catheter structure 100 in the body can be minimized, so that in-vivo insertion and removal of the catheter structure 100 can be smoothly performed while minimizing pain of the patient.
Further, as shown in fig. 4, the rigidity of the catheter structure 100 can also be increased due to the formation structure of the protruding rail 150 formed on the outer side surface of the catheter structure 100.
In practicing the present invention, such a cross-section of the protruding rail 150 may have a triangular, semicircular, semi-elliptical (half over) or hemispherical (half bulb) shape with rounded ends as shown in fig. 4.
In one aspect, in practicing the present invention, a manufacturer may manufacture the 1 st and 2 nd conduits 110 and 120 of fig. 1 and 3 to have the same structure as in fig. 4. Thereby, the 1 st conduit 110 can further reduce the frictional resistance of the outer surface, and the 2 nd conduit 120 can further secure the rigidity required for efficiently transmitting the driving force from the driving device to the 1 st conduit 110.
In the practice of the present invention, on the other hand, the suction end portion of the 1 st duct 110 may be provided with a closed-form rounded foreign matter suction port as shown in fig. 1 alone, or may be cut to form an open-form suction end portion.
Fig. 5 is a diagram showing a structure in which a catheter structure is coupled to a driving device according to an embodiment of the present invention. As shown in fig. 5, the other end of the 2 nd catheter 120 in the catheter structure 100 according to one embodiment of the present invention is provided with a coupling portion 121, and the coupling portion 121 is a region coupled with the mounting hole 200 of the advancing and retreating driving device of the catheter structure 100.
In practicing the present invention, it is preferable that the coupling portion 121 has a cylindrical structure having a cylindrical circumference smaller than that of the 2 nd conduit 120 so as to be more easily coupled to the mounting hole 200.
Meanwhile, an annular coupling groove 123 is formed along the cylindrical circumferential surface of the coupling part 121 on the outer side surface of the coupling part 121, and such an annular coupling groove 123 is preferably formed at a boundary region where the coupling part 121 starts to be formed on the outer surface of the 2 nd conduit 120.
On the other hand, at the coupling end portion of the mounting hole 200 into which the coupling portion 121 is inserted, a plurality of coupling arms 210 for respectively holding the coupling portion 121 are respectively formed to protrude along the cylindrical peripheral surface of the coupling portion 121.
On the one hand, as the coupling portion 121 is gradually inserted into the inner coupling space formed by the plurality of coupling arms 210 arranged in a circular shape, coupling ribs 215 coupled with the annular coupling grooves 123 formed at the coupling portion 121 in a snap-fit manner may be respectively provided.
On the one hand, as shown in fig. 5, as the 2 nd duct 120 is coupled to the mounting hole 200, the suction port 230 forming a communication structure with the 2 nd duct 120 is formed therein, and as the inner diameter of the suction port 230 and the inner diameter of the 2 nd duct 120 are formed to be the same size, the foreign matter sucked through the duct structure 100 can be transferred from the 2 nd duct 120 to the suction port 230 without resistance during transfer.
Meanwhile, in order to prevent foreign matters from leaking to the outside from the coupling end portion of the 2 nd duct 120 and the suction port 230 when the present invention is implemented, a manufacturer sets a coupling ring 300 of a rubber material having the same inner diameter as the inner diameter of the suction port 230 in an inner coupling space formed by the plurality of coupling arms 210 such that the coupling ring 300 is disposed in an inlet region of the suction port 230, which is a bottom surface of the coupling space, and then couples the 2 nd duct 120 such that an end portion of the coupling portion 121 of the 2 nd duct 120 is overlapped with the coupling ring 300.
According to the coupling structure of the 2 nd pipe 120 and the mounting hole 200 as described above, the user can conveniently perform the coupling of the 2 nd pipe 120 and the mounting hole 200 by pushing the coupling portion 121 of the 2 nd pipe 120 into a one touch (one touch) manner of the mounting hole 200 in which the coupling ring 300 is provided.
In one aspect, the coupling structure of the 2 nd conduit 120 and the mounting hole 200 as shown in fig. 5 may be equally applicable to the coupling structure of the conduit structure 100 and the mounting hole 200 of fig. 4 when practicing the present invention.
