[0062] Catheterization involves inserting a flexible tube through the urethra into the bladder to help empty urine.

[0063] In order to prevent the existing urinary catheter from accidentally slipping out, an inflatable balloon is provided at the top. The balloon is placed in the bladder to fix the catheter and prevent it from slipping out. However, the inflatable balloon will occupy a larger space in the bladder after being filled, increasing the probability of friction with the bladder, which can easily cause physical stimulation to the bladder and cause bladder irritation.

[0064] The invention provides a urinary catheter structure.

[0065] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 In one embodiment of the present invention, the urinary catheter structure comprises:

[0066] The catheter 100 is made of a flexible material. It can be understood that the catheter 100 is a tubular structure with a hollow interior and openings at both ends. Further, the flexible material can be silicone or polyurethane, wherein silicone and polyurethane need to have a certain hardness. Further, the catheter 100 is internally structured as a guide hole 110, having a first end 120 and a second end 130 that are relatively arranged, and the first end 120 can be in a bent state; it should be noted that the catheter 100 is placed in the body through the urethra of the penis during installation, wherein the first end 120 is located in the bladder 800. Since the first end 120 can be in a bent state, the first end 120 can also be in a bent state when it is located in the bladder 800. Under the action of the bending device, the catheter 100 can be fixed in the bladder 800. If urination is needed, it can enter the catheter 100 through the first end 120 of the catheter 100, and then be discharged outward through the second end 130. Further, the second end 130 is arranged outside the penis.

[0067] The sleeve 200 and the liquid storage part 300, wherein the sleeve 200 is provided with a first cavity 210, specifically, when in use, the penis is placed in the first cavity 210, so that the sleeve 200 is sleeved on the outside of the penis, wherein in order to make the sleeve 200 fixed on the outside of the penis, the sleeve 200 can be attached to the outside of the penis by tape, further, the first cavity 210 is provided with a liquid guide tube 400, and the second end 130 is detachably connected to the liquid guide tube 400, further, the liquid storage part 300 is connected to the sleeve 200 and communicated with the liquid guide tube 400, so that after the second end 130 is detachably connected to the liquid guide tube 400, the second end 130 can introduce the liquid in the catheter 100 into the liquid guide tube 400, and since the liquid storage part 300 is communicated with the liquid guide tube 400, the liquid in the liquid guide tube 400 can enter the liquid storage part 300, so that the liquid storage part 300 can store liquid. It should be noted that when the first end 120 of the catheter 100 is placed in the bladder 800 in a bent state, the first end 120 in the bent state occupies less space, so that the probability of friction between the first end 120 and the bladder 800 is lower, compared with the inflated small balloon; because the first end 120 occupies less space and the catheter 100 can be fixed in the bladder 800, the catheter 100 can reduce stimulation to the bladder 800 while completing catheterization, reducing the possibility of causing bladder 800 irritation symptoms, thereby solving the technical problems existing in the prior art.

[0068] In one embodiment, the sleeve body 200 is configured to be a soft rubber material. Further, the sleeve body 200 is configured to be a soft rubber material. In some embodiments, the sleeve body 200 can also be configured to be a plastic material. Further, the sleeve body 200 can be attached to the outside of the penis by tape.

[0069] In one embodiment, reference Figure 2 , Figure 4 , Figure 5 , the second end 130 is plugged with the catheter 400, so that the second end 130 can conveniently guide the liquid in the catheter 100 into the catheter 400, and it can also facilitate the connection between the second end 130 and the catheter 400. When the plug-in method is adopted, the catheter 400 can be inserted into the second end 130. In some embodiments, the second end 130 can be inserted into the catheter 400. Further, in some embodiments, the second end 130 and the catheter 400 can be connected by a buckle.

[0070] In one embodiment, reference Figure 2 , Figure 4 , Figure 5The second end 130 is provided with a plug-in portion 150, and the plug-in portion 150 is plugged with the catheter 400. The outer diameter of the plug-in portion 150 is greater than the outer diameter of the catheter 100. Further, the catheter 400 is inserted into the plug-in portion 150. At this time, the plug-in portion 150 can guide the liquid in the catheter 100 into the catheter 400. Further, in some embodiments, in order to facilitate the connection between the plug-in portion 150 and the catheter 400, the plug-in portion 150 can be made of silicone with a higher hardness, which can facilitate the insertion of the catheter 400 into the plug-in portion 150 during the plug-in. It should be noted that a plug-in slot is provided in the plug-in portion 150, and the plug-in slot is connected to the inside of the catheter 100, wherein the catheter 400 is inserted into the plug-in slot. It should be noted that the catheter 400 can be inserted into the plug-in portion 150, or the plug-in portion 150 can be inserted into the inside of the catheter 400.

[0071] In one embodiment, reference Figure 2 , 3 In order to facilitate the liquid in the bladder 800 to enter the catheter 100 faster, a plurality of through holes 140 are provided on the outer side of the first end 120. At this time, after the first end 120 is placed in the bladder 800, since a plurality of through holes 140 are provided on the outer side of the first end 120, the liquid in the bladder 800 can enter the catheter 100 not only through the port of the first end 120, but also through the through holes 140 on the first end 120, thereby improving the speed at which the liquid in the bladder 800 enters the catheter 100.

[0072] In one embodiment, reference Figure 1 , Figure 2 The first end 120 can be bent in an arc shape. When the arc shape is adopted, on the one hand, the catheter 100 can be fixed in the bladder 800, and on the other hand, it can also reduce the stimulation to the wall of the bladder 800 and reduce the friction to the bystander.

[0073] In one embodiment, reference Figure 4 , Figure 6 The sleeve 200 is provided with an adhesive layer 220, and the adhesive layer 220 can fix the sleeve 200 on the penis, wherein the sleeve 200 is sleeved on the penis, and it can be understood that the sleeve 200 can be fixed on the penis through the adhesive layer 220, which can prevent the sleeve 200 from separating from the penis, thereby preventing the liquid in the penis urethra that has not entered the catheter 100 from flowing out. Further, in some embodiments, an elastic band with a ring structure can be provided on the outside of the sleeve 200, and the sleeve 200 is restricted on the penis by the elastic band.

[0074] In one embodiment, reference Figure 4 , Figure 6The adhesive layer 220 is located in the first cavity 210 and is arranged at the cavity opening, so that the adhesive layer 220 can reduce the contact between the adhesive layer 220 and objects such as clothes and bedding. In some embodiments, the adhesive layer 220 can be arranged outside the sleeve 200, and at least part of the adhesive layer 220 does not contact the sleeve 200, and the part of the adhesive layer 220 that does not contact the sleeve 200 is used to stick to the penis.

[0075] In one embodiment, reference Figure 6 The liquid guide tube 400 includes a first connecting tube 410 and a second connecting tube 420 that are connected to each other. The sleeve 200 is provided with a liquid guide hole 230. The first connecting tube 410 is arranged inside the first cavity 210 and connected to the liquid guide hole 230. The second connecting tube 420 is arranged outside the sleeve 200 and connected to the liquid guide hole 230. The first connecting tube 410 is connected to the catheter 100, and the second connecting tube 420 is connected to the liquid storage part 300. The inner circumference diameter of the second connecting tube 420 is greater than the outer circumference diameter of the first connecting block. It should be noted that since part of the liquid does not pass through the inside of the catheter 100 but is discharged from the outside of the catheter 100, some liquid will remain inside the sleeve 200 at this time. The residual liquid can enter the liquid storage part 300 through the liquid guide hole 230, which can reduce the possibility of liquid remaining in the sleeve 200.

[0076] In one embodiment, reference Figure 8 The first connecting tube 410 and the second connecting tube 420 are coaxially arranged, and the first connecting tube 410 is connected to the liquid guide hole 230 through the connecting rod 240. When the first connecting tube 410 and the second connecting tube 420 are coaxially arranged, the liquid in the catheter 100 can enter the second connecting tube 420 more smoothly after passing through the first connecting tube 410, thereby facilitating the liquid to enter the liquid storage part 300.

[0077] In one embodiment, reference Fig. 9 The liquid storage part 300 is configured as a liquid storage bag, and a third connecting tube 500 is arranged on the outside of the liquid storage part 300. One end of the third connecting tube 500 is plugged into the second connecting tube 420, and the other end is connected to the liquid storage bag. It can be understood that the liquid in the second connecting tube 420 can enter the liquid storage bag through the third connecting tube 500, that is, the third connecting tube 500 can guide the liquid in the second connecting tube 420 into the liquid storage bag.

[0078] In one embodiment, reference Fig.10 , Fig.11 , Fig.12In order to facilitate the insertion of the catheter 100 into the body through the urethra in the penis, the urinary catheter structure further includes a guide tube 600, a balloon arranged inside the guide tube, and an inflation channel connected to the balloon. The balloon is arranged near the head end of the guide tube, and the end of the inflation channel is configured as an inflation port. It should be noted that in some embodiments, the end of the inflation channel can be arranged at the end of the guide tube. Of course, in order to facilitate the use of the inflation port, the inflation port can also pass through the end of the inflation channel and be located on the outside of the guide tube. At this time, the inflation port and the balloon are connected by a pipeline, and the pipeline is fixed on the inner wall of the guide tube. Furthermore, a through hole 610 is provided on the tube body of the guide tube, and the through hole 610 is arranged close to the head end and is located below the balloon. In this way, when the guide tube is inserted into the bladder, the liquid in the bladder can enter the guide tube through the hole 610 and be discharged out of the body along the guide tube. It should be noted that the through hole 610 is arranged below the balloon to ensure that the balloon can be accurately inserted into the bladder. The balloon 700 has an expanded state and a contracted state. In some embodiments, inflating the balloon 700 through the inflation port can make the balloon 700 in an expanded state, and pumping air into the balloon 700 through the inflation port can make the balloon 700 in a contracted state. Furthermore, the device used for inflation and pumping air can be a syringe. It should be noted that the syringe is fixed to the inflation port when in use, and before the syringe is connected to the inflation port, a certain amount of air remains inside the syringe. After the syringe is connected to the inflation port, the syringe is pushed so that the air in the syringe can rush into the balloon. If pumping air is required, the syringe can be pulled to pump out the gas in the balloon. In the expanded state, the guide tube 600 and the balloon 700 can clamp the first end 120 of the catheter 100; in the contracted state, the first end 120 can pass through the guide tube. It should be noted that the balloon remains in the contracted state, and then the catheter is inserted into the guide tube so that the first end is close to the balloon. Then a certain amount of air is injected into the balloon through the inflation port using a syringe. At this time, the balloon changes from a contracted state to an expanded state. The balloon in the expanded state can cooperate with the inner wall of the guide tube to clamp the first end. It should be noted that at this time, the second end of the catheter passes through the end of the guide tube and is located outside the guide tube, and the first end can be in a vertical state or a bent state.Then, the guide tube, the inflated balloon, and the catheter are inserted into the urethra along the penis opening until they are inside the bladder. When the liquid in the bladder passes through the hole 610 and enters the guide tube and flows out of the guide tube, the gas in the balloon is extracted by a syringe to shrink the balloon. Then, the catheter is operated to pass the first end through the guide tube and gradually withdraw the catheter until it is outside the urethra. At this time, the first end of the catheter is left in the bladder. Since the first end of the catheter is in a bent state, the first end can better fix the catheter in the urethra. Then, the second end of the catheter is fixed on the sleeve 200, and then the sleeve is put on the penis and fixed to the penis. Finally, the liquid storage part and the sleeve are connected.

[0079] The present invention further provides an installation method, which is applied to a urinary catheter structure, wherein the urinary catheter structure is as described in any of the above embodiments, wherein the urinary catheter structure includes a guide tube 600 and a balloon 700.

[0080] refer to Figures 10 to 17 , the installation method comprises:

[0081] S10, placing the first end of the catheter in the guide tube and between the balloon and the guide tube, at which time the balloon is in a contracted state (refer to Fig.11 ), and then inflate the balloon through the inflation port, and the guide tube and the inflated balloon clamp the first end (reference Fig.12 );

[0082] S20, insert the first end of the guide tube, the balloon, into the urethra along the penis opening until it enters the bladder, at which point the liquid in the bladder can flow into the guide tube through the opening, and the second end of the catheter is located outside the penis (reference Fig.13 );

[0083] S30, partially extract the gas in the balloon through the inflation port to make the balloon in a contracted state, and then withdraw the guide tube and the balloon from the urethra. At this time, the first end passes through the guide tube and is left in the bladder in a bent state (refer to Fig.14 , Fig.15 );

[0084] S40, connecting the liquid guide tube to the second end, then sleeve the sleeve body outside the penis and fix it to the penis, then connect the liquid storage part to the sleeve body and communicate with the liquid guide tube (refer to Fig.16 ).

[0085] It should be noted that the balloon remains in a contracted state, and then the catheter is inserted into the guide tube so that the first end is close to the balloon, and then a certain amount of air is injected into the balloon through the inflation port using a syringe. At this time, the balloon changes from a contracted state to an expanded state. The balloon in the expanded state can cooperate with the inner wall of the guide tube to clamp the first end. It should be noted that at this time, the second end of the catheter passes through the end of the guide tube and is located outside the guide tube, and the first end can form a vertical state (see Figure 3 ) or bent state (see Figure 2 ). Then, the guide tube, the balloon in the expanded state, and the catheter are inserted into the urethra along the penis opening until they are in the bladder. When the liquid in the bladder enters the guide tube through the hole 610 and flows out of the guide tube, the next step is to extract the gas in the balloon through the syringe to make the balloon in a contracted state, and then operate the catheter to pass the first end through the guide tube and gradually withdraw the guide tube until it is outside the urethra. At this time, the first end of the catheter is left in the bladder. Since the first end of the catheter is in a bent state, the first end can better fix the catheter in the urethra. Then, the second end of the catheter is fixed on the sleeve 200, and then the sleeve is put on the penis and fixed to the penis. Finally, the liquid storage part and the sleeve are connected.

[0086] It can be understood that by adopting the first end 120 of the catheter 100 in a bent state, when the first end 120 of the catheter 100 is placed in the bladder 800 in a bent state, the first end 120 in the bent state occupies less space, so that the probability of friction between the first end 120 and the bladder 800 is lower, compared with the inflated small balloon; because the first end 120 occupies less space and the catheter 100 can be fixed in the bladder 800, the catheter 100 can reduce stimulation to the bladder 800 while completing catheterization, and reduce the possibility of causing bladder 800 irritation symptoms, thereby solving the technical problems existing in the prior art.
