A schematic cross-sectional view of device 100. The indwelling catheter device 100 can be applied to a bladder fistula operation. When the bladder fistula channel is formed between the bladder and the body surface, the indwelling catheter device 100 can be placed in the bladder fistula channel, thereby allowing the urine to be removed from the bladder. The bladder is directed to the outside rather than excreted through the urethra. The indwelling catheter device 100 includes an elastic tube 110, a stopper 120, and a backflow prevention member 130. In one example, the elastic tube 110 may be made of a soft and resilient material such as rubber. The elastic tube 110 has a main passage 111 and a relative Head end 110A and tail end 110B. The main passage 111 penetrates the elastic tube 110 and has a first main passage opening 111A and a second main passage opening 111B at the head end 110A and the tail end 110B, respectively. In an example, urine in the bladder may flow from the second main passage opening 111B of the main passage 111 to the first main passage opening 111A and be discharged outside the body.

The stopper 120 is disposed on the head end 110A. In one example, the size of the stop member 120 is greater than the size of the ostomy channel opening. When the indwelling catheter device 110 of the present embodiment is inserted into the ostomy channel, the stopper 120 can prevent the indwelling urinary device 110 from being inserted into the ostomy channel too deeply to damage the bladder. In another example, the stop 120 is a slightly flat structure. When the indwelling catheter device 110 of the present embodiment is inserted into the ostomy channel, the stopper 120 is flat against the body surface, and has the advantages of good appearance and difficulty in pulling the pipe.

The backflow prevention member 130 is disposed in the main passage 111 to prevent the urine in the bladder from flowing out to the outside of the body when it is not normally placed in the catheter. In an example, the backflow prevention member 130 is located approximately at the center of the main passage 111. In another example, the number of anti-backflow members 130 may be plural.

In an example, the indwelling catheter 100 of the presently disclosed embodiment can also include an elastomeric fastener 140. The elastic fastener 140 is slightly disk-shaped and is disposed on the elastic tube 110. In one example, the elastic fastener 140 can be disposed at the trailing end 110B of the indwelling urinary catheter 100 to thereby entrap the trailing end 110B of the indwelling urinary catheter 100 within the bladder. In other words, the head end 110A and the tail end 110B of the indwelling urinary catheter 100 of the present embodiment are respectively subjected to the action of the stopper 120 and the elastic fastener 140, thereby further fixing the indwelling catheter 100 Set in the bladder 160. In one example, the length of the elastic tube 110 between the stop member 120 and the resilient fastener 140 is slightly greater than or equal to the length of the ostomy channel.

In one example, the indwelling catheter device 100 of the presently disclosed embodiment can also have a secondary channel 112 that communicates with the resilient fastener 140 and has a secondary channel 112A at the tip end 110A. In an example, the secondary channel 112 can have multiple effects. Please refer to FIGS. 1B, 2A and 2B. FIG. 2A is a side elevational view showing the insert 150 of the indwelling catheter device 100 according to an embodiment of the present invention. FIG. 2B is a schematic view showing the use of the insert 150 of the indwelling catheter 6 according to an embodiment of the present invention. In an example, the length L _{1 of the} insert 150 can be greater than the length L _{2 of the} secondary channel 112. When it is desired to place the indwelling catheter 6 in the ostomy channel, the insert 150 can be inserted into the secondary channel 112 first. Since the elastic tube 110 and the elastic fastener 140 have elastic properties, when the insert 150 is completely inserted into the auxiliary passage 112, the entire elastic tube 110 and the elastic fastener 140 are deformed, wherein the elastic tube 110 is elongated and the elastic fastener 140 is elasticized. It will change from a disc shape to a flat shape. Thereby, the tail end 110B of the indwelling catheter device 100 can be smoothly inserted into the bladder fistula channel without being blocked by the elastic fastener 140. Thereafter, it is determined by the locking action of the stopper 120 that the position of the elastic fastener 140 of the indwelling catheter 6 is already in the bladder (because the elastic tube 110 between the stopper 120 and the elastic fastener 140 is located). The length is slightly greater than or equal to the length of the ostomy channel, and the insert 150 can be withdrawn from the secondary channel 112 to restore the resilient fastener 140 to a disc shape, thereby securing the indwelling urinary catheter 100 in the bladder 160.

Referring to FIGS. 1B and 3A together, FIG. 3A is a schematic view showing the use of an indwelling catheter 6 according to an embodiment of the present invention. In order to enhance the effect of the indwelling urinary catheter 100 being fixed in the ostomy channel, when the indwelling urinary catheter 100 is disposed behind the ostomy channel, a fluid such as a liquid or a gas may be poured from the auxiliary passage port 112A, and then the subchannel may be sealed. The mouth 112A is slightly expanded by the pressure of the elastic fastener 140 to form a slightly spherical elastic fastener 140, so that the tail end 110B of the elastic tube 110 is in an expandable spherical shape, thereby avoiding or reducing the indwelling catheter. The opportunity for the device 100 to detach from the ostomy channel.

Please refer to FIG. 3B. FIG. 3B is a schematic view showing the use of an indwelling catheter 6A according to an embodiment of the present invention. The overall structure of the indwelling catheter 6A is similar to the indwelling catheter 100 except that the indwelling catheter 100A does not have the elastic fastener 140 and the trailing end 111B of the elastic tube 110 is curled. shape. The curled end 111B has the effect of resembling the elastic fastener 140, that is, the indwelling catheter 6A can be secured in the bladder 160, avoiding or reducing the problem of the indwelling catheter 100A being detached from the ostomy channel.

In an example, the indwelling catheters 100 and 100A of the various embodiments of the present invention can be inserted into the elastic tube 110 using a sterilized catheter when the user is to perform the operation of discharging the urine after being disposed in the ostomy channel. In the main channel 111, urination can be performed.

In a specific example, the indwelling catheter of the present invention further comprises a liquid infusion channel, and the end of the infusion channel is connected to a resilient receiving portion. When the indwelling catheter is placed in the correct position, the distilled water is passed through the infusion channel. The top end is injected, and the elastic receiving portion is expanded to form a water ball. After injecting an appropriate amount of distilled water, the top end of the infusion channel is closed, so that the distilled water does not leak, and the water ball can be fixed in the bladder by the aforementioned water ball, thereby avoiding the indwelling catheter to be detached from the bladder.

In summary, the indwelling catheter device of the present invention can be placed in the bladder fistula channel, so that the discomfort of the catheter into the urethra can be avoided. In addition, when there is no need for catheterization, the anti-backflow member can be used to prevent urine from flowing out; and if catheterization is required, a sterile catheter can be inserted for catheterization, so it is necessary to avoid the use of the indwelling catheter. Carrying the urine bag all the time, and always pay attention to the problem of not pulling the pipe.
