Abstract

(57) [Summary] [PROBLEMS] To insert a urinary catheter into a person who has difficulty in urinating by himself / herself, so that even an amateur can easily, properly and safely perform urination. SOLUTION: A range of about 20 cm on the introduction side of the catheter having a length of about 40 cm to 50 cm is formed as a double cylinder. At this time, the inside diameter of a certain length range at the leading end of the double cylinder is made substantially the same as the outside diameter of the catheter, and there is a certain gap between the inside diameter of the other parts other than this and the outside diameter of the catheter. Or the distal end of the catheter is inserted into a position slightly retreated from the distal end of the double cylinder.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a urinary catheter.

[0002]

[Prior art]

 Urinary drainage is performed using a urinary catheter for those who have a weakened body during or after illness and have difficulty urinating on their own, which has an inner diameter of 2.5 mm. The procedure is carried out by inserting a synthetic resin tube having an outer diameter of about 4.5 mm and a length of about 33 cm into the urinary canal to reach the inside of the bladder.

[0003]

[Problems to be solved by the invention]

 To insert the urinary catheter into the urine guide hole as described above, remove the urinary catheter from the wrapping paper while pinching it with tweezers, and then insert the urine guiding catheter into the urine guide hole while pinching it. This is to keep the sterilized catheter from touching for hygiene reasons. For patients in the middle, disinfection of the hands and other problems have been confused. The present invention is intended to solve the above problems.

[0004]

[Means for Solving the Problems]

 In the present invention, a double-cylinder has a length of about 40 cm to 50 cm and a range of about 20 cm on the introduction side of the catheter. At this time, the inside diameter of a certain length range at the leading end of the double cylinder is made almost the same as the outside diameter of the catheter, and the inside diameter of the other parts except this is a certain gap between the outside diameter of the catheter and the outside diameter. And the catheter is inserted so that the distal end of the catheter is slightly retracted from the distal end of the double tube.

[0005]

[Embodiment of the invention]

 FIG. 1 is a partially cutaway front view of the product of the present invention. Reference numeral 1 denotes a urinary catheter, which is a synthetic resin tube having an inner diameter r of 2.5 mm and an outer diameter R of 4.5 mm, and a length L of about 40 cm to 50 cm. Reference numeral 2 denotes a double cylinder of the same material which is fitted on the introduction side of the urinary catheter 1 and has a length 1 of about 20 cm.

FIG. 2 shows another embodiment. In the above embodiment, the double tube 2 comes into contact with the inner wall surface m of the urinary catheter 1 within a length 1 thereof, that is, in a range of about 20 cm on the distal end side of the urinary catheter 1. However, in the present embodiment, only the fixed length range of the head portion is made to contact, and the other portions are formed so as to have a fixed gap t. In this embodiment, the dimension E is about 1 cm, and t is about 2 mm.

The products manufactured in each of the above embodiments are extremely sanitary because they are all assembled and packaged in a sterilized state at the manufacturing stage. However, when the product is taken out of the packaging bag, it becomes an introduction side. The urine catheter tip p may be slightly retracted into the double cylinder 2 so as to be in a hidden position as shown in the figure so as not to be unsanitary. Alternatively, a disposable cap may be attached to the part.

However, in the present invention having the above-described structure, when using it, when taking it out of the packaging bag, even with the conventional product, even if the hands are sufficiently disinfected and disinfected, be careful not to touch them with tweezers. In the present invention, the thigh is inserted into the urethra without using tweezers, that is, even when the double tube 2 is directly held by hand. Since the portion of the urinary catheter 1 is concealed inside the cylinder and is hygienically protected, the portion is applied to the urethral hole while directly touching it, and the urine catheter 1 is moved out of the double cylinder 2. The catheter which has a protruding portion of the catheter 1 held by hand and which is pushed into the double cylinder 2 sequentially, so that the catheter is very smoothly concealed in the double cylinder 2. One part is inserted into the urethral foramen It's going to go.

[0009] The product of the present invention shown in FIG. 1 is disposable by use of a single cut, while the product shown in FIG. 2 is that the catheter 1 pulled out from the urethral hole after use is immersed in a disinfectant solution. In other words, the catheter 1 and the double cylinder 2 containing the same are immersed in a sterilizing solution together with the double cylinder 2 and the catheter 1 during sterilization. Since a gap t is formed between them, the disinfectant solution enters the portion and the catheter 1 at the portion to be inserted again into the urethral hole is safely sterilized and disinfected.

[0010]

[Effect of the invention]

 The present invention is configured as described above, and since the urinary catheter can be handled manually without using tweezers, it is simple, quick and accurate without requiring much smelting. Even if the part to be introduced into the urethral canal is taken out of the packaging bag, it is shaded in the double cylinder and is still in contact with falling bacteria. Therefore, it is extremely sanitary and highly secure. In particular, it will be safe and convenient for the home rescuer to use it independently. According to the second aspect of the invention, it is possible to reuse the fuel cell and to achieve an excellent economic effect. According to the third aspect of the invention, it is possible to enhance the sanitary safety of the introduction tip. Will contribute.
