Description

  The present invention relates to a catheter for urethral insertion with an improved head portion. More specifically, the present invention relates to a catheter for urethral insertion with an improved head portion for preventing the upper end of the catheter from becoming difficult to be pulled out by being caught in a housing tube when the upper end of the catheter is detached from the stopper.

  As is well known, a catheter is a tube that is inserted into the urethra as a flexible microtubule. At this time, in the case of a catheter inserted into the urethra, the catheter is temporarily inserted into the urethra of a patient with dysuria and performs the function of discharging urine to the outside. Or stored outside the body.

  Therefore, a separate storage container for the disinfection and storage of such a catheter has been developed.

  FIG. 1 is a perspective view showing an outer shape of a storage container for a catheter for urethral insertion according to the prior art, FIG. 2 is a perspective view showing a storage state of the storage container for a catheter for urethral insertion according to the prior art, and FIG. It is a principal part expanded sectional side view which shows the accommodation state of the container of the catheter for urethral insertion by the technique of this.

  Referring to this drawing, a urethral insertion catheter storage container 2 according to the prior art is formed in the shape of a long tube, and a container portion 4 is constructed in which one end is closed and the catheter 30 can be stored therein. The container 4 is composed of an upper container 6 and a lower container 8 with a central corrugated pipe 10 as a reference. The corrugated pipe 10 is a means for easily carrying and storing the upper container 6 and the lower container 8 by folding them.

  An upper leave 12 coupled to the outer periphery of the upper container 6 is formed at a predetermined portion of the outer periphery of the upper portion of the upper container 6, and a coupling hole 14 is formed vertically on one side of the upper leave 12. It is comprised so that the end of the hanger 20 may be couple | bonded.

  The hanger 20 is formed with a protrusion 22 at one end for preventing the hanger 20 from being detached from the coupling hole 14, and a central portion thereof is bent so as to be hooked on a hook (not shown) of a drug support (not shown). An engaging portion 24 is formed, and an insertion portion 26 is extended to the other end of the engaging portion 24.

  A lower rib 16 coupled to the outer peripheral edge of the lower container 8 is formed at a predetermined portion of the outer peripheral edge of the lower portion of the lower container 8, and the lower leave 16 has an insertion hole 18 formed vertically on one side. It is comprised so that the edge part of the insertion part 26 may be couple | bonded.

  The end of the upper container 6 is open, the catheter 30 can be accommodated therein through its open inlet, and a plug 28 coupled to the upper container 6 to seal the open end. It is configured. The outer periphery of the plug 28 is formed by a polygonal surface 28a.

  Further, the plug 28 is configured with a coupling protrusion 39 protruding downward on the lower surface thereof, and the coupling protrusion 39 is sandwiched between the upper ends of the catheter 30 so that the catheter 30 can be easily removed from the container section 4 in the future. Configured as follows.

  Reference numeral 40 denotes the head portion 40 of the catheter 30. The head portion 40 is provided with an opening 42 having an open upper portion, and projections 42 for increasing the coupling force are formed at regular intervals. Has been. On the outer peripheral edge of the upper portion of the upper container 6 is formed a screw portion 6a for coupling with the stopper 28 at regular intervals.

  The urethral insertion catheter storage container 2 according to the prior art is prepared by injecting a disinfectant into the container part 4 when the catheter 30 needs to be sterilized, and then inserting the catheter 30 into the container part 4 with a stopper 28. The catheter 30 can be stored or disinfected by honey-closing.

  However, when the storage container 2 of the catheter for urethral insertion according to the prior art tries to pull out the catheter 30 stored in the container section 4, the catheter 30 is inserted into the coupling protrusion formed at the lower end of the plug 28 when the plug 28 is opened. In this state, the catheter 30 is pulled out together with the stopper 28, but at this time, the coupling protrusion of the stopper 28 and the catheter 30 are often in a simple sandwiched state, so that they may be separated. It was.

  Once the stopper 28 and the catheter 30 are separated, the catheter 30 in the catheter storage container 2 cannot be picked out with fingers or other objects due to the concern of contamination, so the catheter 30 is accommodated in the catheter storage container 2 together with the catheter 30. Since the catheter 30 has to be pulled out by a method of discarding all of the disinfectant, there is a problem that an expensive disinfectant is wasted in this case.

  In addition, the diameters of the upper container 6 and the lower container 8 are too large, and there is a problem that the injection amount of the disinfectant for disinfecting the catheter 30 increases. In particular, the disinfectant had to be injected into the container several times, which was expensive.

  Therefore, in order to solve the above problems, the present applicant has developed a storage container shown in FIG.

  FIG. 4 is a perspective view showing the outer shape of a storage container of a catheter for urethral insertion according to another conventional embodiment.

  Referring to this drawing, a storage container 100 for a catheter for urethral insertion according to another conventional embodiment is also provided with a corrugated pipe 108 that can be bent and retracted in the center of the container section 102, and both ends of the corrugated pipe 108. Are provided with small-diameter receiving tubes 110 and 112, respectively.

  Since the small-diameter receiving tubes 110 and 112 are configured to be narrower than the diameter of the existing container portion, the amount of drug that must be filled in the container portion 102 can be reduced.

  The upper container 104 and the lower container 106 are extended to both ends of the receiving pipes 110 and 112 to have a diameter larger than the diameter of the receiving pipes 110 and 112, respectively. It is shorter than the length of the receiving pipes 110 and 112.

  The connecting portion between the upper container 104 and the receiving tube 110 is provided with a locking portion 114 on which the head portion of the catheter 138 (see FIG. 3: 40) is applied.

  The plug 132 configured in the conventional invention has protrusions 136 formed at regular intervals along the outer peripheral edge 134 so that the user can easily open and close it.

  In addition, the urethral insertion catheter storage container 100 according to another conventional embodiment is also provided with a hanger 120 that is hung on a hanger (not shown) of a liquid container provided in a hospital room, or hung on a wall or a nail. The hanger 120 is configured such that the lower container 106 can be easily coupled to the upper container 104 without tilting the storage container 100 for the catheter for inserting the urethra.

  For this purpose, a leave 122 is coupled to the outer peripheral edge of the upper container 104 so as to wrap around the outer peripheral edge, and a support base 124 extending laterally from a predetermined portion of the outer peripheral edge of the leave 122 is formed. A holder 126 to which the receiving tube 112 is coupled is formed at the end of the support base 124.

  The holder 126 is formed with an incision portion 126a in which an outer peripheral edge thereof is partially incised so that the holder 126 can be coupled to a plurality of anti-movement protrusions 106a formed on the outer peripheral surface of the lower container 106.

  Therefore, when the user holds the upper container 104 with one hand and folds the lower container 106 with another hand, the lower container 106 is moved in a straight line with the upper container 104 while the corrugated pipe 108 is folded. A person can be easily coupled by being sandwiched between the anti-movement protrusions 106 a formed on the outer peripheral edge of the lower container 106 by the incision 126 a of the holder 126.

  In this case, unlike the conventional invention, it is not necessary to adjust the leave according to the insertion stage, and it is not necessary to sandwich a separate lower leave between the containers, so that convenience is high and economical.

  On the other hand, an extension pin 128 is formed at the center of the support base 124, and a locking hook 130 that is movably coupled to the extension pin 128 is formed. The locking hook 130 is hooked on a nail or other hanger hook (see FIG. 2: 32). The locking hook 130 is movably coupled to an extension pin 128 formed in the center of the support base 124. Therefore, the storage container 100 for the catheter for inserting the urethra can be hung without tilting to one side, and the locking hook 130 can be freely moved with respect to the extension pin 128, so that it is not easily detached from the hanger hook 32 and is stable. Can be hung.

  However, the connecting portion between the upper container 104 and the receiving tube 110 is formed with a locking portion 114 that allows the head portion of the catheter 138 (see FIG. 3: 40) to be applied. This is actually a tapered type. There is a problem that the constructed head portion 40 is further sandwiched between the accommodating pipes 110 having a small diameter, which makes it more difficult to pull out.

  Accordingly, the present invention has been made in view of the above problems, and an object of the present invention is to prevent the upper end of the catheter from becoming difficult to be pulled out by being caught in the housing tube when being detached from the stopper. It is an object of the present invention to provide an improved urethral catheter.

  In order to solve the above-described problems, according to one aspect of the present invention, a disinfectant is accommodated, a small-diameter storage tube that communicates with an upper container and a lower end of the upper container, and the upper container and the storage tube. In a catheter for urethral insertion that is accommodated together in a storage container comprising a locking portion whose connecting portion is formed obliquely, a head portion whose upper end is opened so as to be coupled with a coupling projection of a stopper provided in the storage container And an insertion tube that is coupled to communicate with the lower end of the head portion and is inserted into the urethra, and the head portion is a locking portion formed between the upper container and the accommodation tube at the lower end. Thus, a urethral insertion catheter having an improved head portion including a locking projection larger than the diameter of the receiving tube is provided.

  Here, the head portion may be a taper type in which the inner passage is wide and narrow so that the coupling protrusion of the stopper can be easily coupled.

  Further, a value obtained by combining the length of the coupling protrusion and the length of the head portion may be configured to be larger than the length of the upper container.

  As described above, according to the present invention, even when the catheter having the upper end coupled to the coupling projection of the stopper is separated inside the storage container regardless of the intention, the head of the upper end of the catheter is not affected. Since the locking protrusion is formed on the outer peripheral edge and the locking protrusion can prevent the catheter from dropping deeply into the storage container, the catheter can be easily taken out of the storage container using the coupling protrusion. There is an advantage that you can.

  FIG. 5 is an enlarged cross-sectional side view of a main part illustrating a state in which a container of a catheter for urethral insertion with an improved head portion according to an embodiment of the present invention is accommodated.

  Referring to this, the catheter for urethral insertion 138 with an improved head according to an embodiment of the present invention is a catheter for preventing the upper end of the catheter from becoming difficult to be pulled out by being caught in a receiving tube when the upper end of the catheter is removed from the stopper. It is.

  As described above, the upper container 104, the small-diameter housing pipe 110 that contains the disinfectant and communicated with the lower end of the upper container 104, and the connecting portion of the upper container 104 and the housing pipe 110 are configured obliquely. If the head portion 40 of the catheter 30 is configured to have a tapered shape with an upper, lower, and narrow shape as shown in FIG. When the head portion 40 is detached from the portion 39 regardless of the intention, the outer peripheral edge at the lower end of the head portion 40 is sandwiched by the small-diameter housing tube 110 and is more difficult to pull out.

  Therefore, the urethral insertion catheter 138 with an improved head portion according to an embodiment of the present invention has an improved structure for preventing the head portion 140 from being pinched.

  First, the urethral insertion catheter 138 with an improved head according to an embodiment of the present invention is formed with an open port 142 at the upper end so as to be coupled with the coupling protrusion 139 of the stopper 132 provided in the storage container 100. A head portion 140 is provided.

  In addition, the lower end of the head unit 140 is connected to the head unit 140 so as to communicate with the insertion unit 148 and is inserted into the urethra. The lower end of the head unit 140 is connected to the upper container 104 at the lower end. Locking projections 146 larger than the diameter of the storage tube 110 are formed so as to engage with the locking portions 114 formed between the storage tubes 110.

  At this time, the head portion 140 is made of soft polyurethane whose material is the same as that of the insertion tube 148, and the head portion 140 has a passage inside thereof that is easy to be coupled to the coupling protrusion 139 of the plug 132. It is composed of a narrow taper type.

  Further, the head part 140 is configured such that coupling protrusions 144 are formed at regular intervals around the inside of the head part 140 to increase the coupling force with the coupling protrusion 139.

  That is, the head portion 140 of the catheter 138 for urethral insertion with an improved head portion according to an embodiment of the present invention is arranged so that the passage inside thereof is easily coupled to the coupling protrusion 139 of the plug 132. In the case of the tapered shape of the narrow shape, but in the case of the outer surface, as in the case of the internal structure, the tapered shape of the upper and lower narrow shape, the catheter 138 is removed from the stopper 132 unintentionally. The lower end of the head portion 140 is sandwiched in a narrow accommodating tube 110 as shown in FIG.

  Therefore, the head portion 140 of the urethral insertion catheter 138 with an improved head portion according to an embodiment of the present invention has a tapered shape whose outer surface is wide, narrow and narrow like the internal structure, but its lower end. The portion is formed with a locking projection 146 having a diameter larger than the diameter of the receiving tube 110 on the outer side, so that the locking projection 146 can be removed even if the catheter 138 is detached from the stopper 132 unintentionally. However, it is easy to pull out to the outside of the storage container 100 by using the coupling protrusion 139 of the stopper 132 and the like on the inlet portion of the storage tube 110.

  At this time, in the present invention, it is preferable that a value obtained by combining the length of the coupling protrusion 139 and the length of the head portion 140 is larger than the length of the upper container 104. This is because, even when the catheter 138 is detached from the stopper 132 regardless of the intention, the head portion 140 that is applied to the inlet portion of the receiving tube 110 can be easily pulled out by using the coupling protrusion 139 of the stopper 132.

  Note that the present invention is not limited to the configuration of the locking projection 146, and the outer diameter of the position where the locking projection 146 is formed so that the catheter 138 can be covered at the entrance of the storage tube 110 of the storage container 100. The same effect can be obtained when the diameter is made larger than the inner diameter of the receiving tube 110.

  The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious that a person having ordinary knowledge in the technical field to which the present invention pertains can come up with various changes or modifications within the scope of the technical idea described in the claims. Of course, it is understood that these also belong to the technical scope of the present invention.
