Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not intended to limit the present invention.

Please refer to FIG. 1, the present utility model provides an anti-urination tube: including a balloon irrigation head 1, a urine tube joint 2, a flushing joint 3, a urinary catheter 5 and a balloon 8, the balloon irrigation head 1, the urine tube The pipe joint 2 and the flushing joint 3 are integrated with the upper end of the urinary catheter 5 through the silicone pipeline, and are respectively opened to the lower end of the urinary catheter through three independent channels, the balloon irrigation head 1, the urinary tube joint 2 and the flushing joint 3. The bladder 8, the urethral port 6 and the flushing port 7 are respectively opened to the balloon 8, the urethral port 6 and the flushing port 7 through the independent pipeline passages in the urinary catheter 5. The lower end of the tube is closed, and the catheter with the closed lower end is more conducive to intubation into the urethra.

The conventional balloon is spherical. After the liquid is injected, the balloon is inflated and stuck in the bladder to prevent the tube from falling off. However, due to the inconsistent state of the urethral opening of different patients, some patients have loose urethra, which is easy to cause slippage. It is difficult to find when the balloon is not completely detached during the slippage process. The balloon 8 of the present invention is in the shape of a flat disc or a wheel closed on the outside, and the axis coincides with the catheter, and includes an outer wheel 81 with an annular cavity and a spoke 82 connecting the outer wheel and the balloon perfusion channel, The spokes 82 are tubular in a full state, and the balloon 8 is arranged 3-6 cm above the ureteral orifice 6 . The diameter of the outer wheel 81 of the balloon 8 is 2.5-4.5 cm. The volume of the wheel-shaped or disc-shaped balloon is not larger than that of the spherical balloon, but when the balloon is filled with liquid, the wheel-shaped balloon will open, and the diameter is significantly larger than the inner diameter of the urethra, and the urinary catheter is difficult to slip. After the fluid in the balloon is released, the balloon shrinks and the volume becomes significantly smaller, which can be easily taken out. When the balloon enters the bladder, since the balloon is not filled with liquid or gas, it can be completely folded on the outer wall of the urinary catheter and enter the bladder with the urinary catheter.

A detection device 9 is provided. The detection device 9 includes a button battery 91, a buzzer 92, a wire 93 and a photoelectric sensor 94. As shown in FIG. The outer side of the tube is used to detect whether the balloon comes out. The photoelectric sensor 94 is provided with a photoelectric transmitter 95 and a photoelectric receiver 96. The photoelectric sensor 94 is connected to the circuit board provided in the balloon filling head through wires. The circuit board is provided with a buzzer 92. An alarm sounds when the photoelectric sensor 94 is exposed outside the urethra.

As shown in FIG. 2, as an embodiment of a detection circuit, a comparator 97 is provided on the circuit board, and the phototransmitter 95 is connected to the two poles of the power supply through a resistor. When the circuit switch is turned on, the phototransmitter 95 continues to emit light. , Usually an infrared tube is used as the photoelectric transmitter, and the photoelectric receiver 96 corresponding to the wavelength is an infrared receiving tube. Usually, the infrared transmitting tube and the infrared receiving tube are integrated, only three terminals, SMD package, small volume, only diameter There is about 2mm, which can be covered on the surface of the catheter. The output end of the photoelectric receiver 96 is connected to one input end of the comparator 97, and the other input end of the comparator is connected to the voltage divider. In the embodiment of FIG. 2, the infrared receiving tube is a PNP tube, and the collector is the The output terminal is connected to the inverting input terminal of the comparator, the positive input terminal is connected to the voltage divider, the output terminal of the comparator drives the buzzer 92 through a triode, and the buzzer can use the DC buzzer with built-in oscillator . The buzzer is a DC buzzer, the positive terminal is connected to the positive pole of the power supply, the negative terminal is connected to the collector of the NPN type driving transistor, and the NPN type driving transistor emitter is connected to the negative pole of the power supply.

Therefore, when the urine tube is not released, the infrared receiving tube can receive the infrared rays reflected by the infrared transmitting tube at close range in the body. level, the driving transistor of the NPN type is turned off, the buzzer is in an open circuit, and no sound is emitted. When the urine tube is pulled out, the infrared receiving tube cannot receive the infrared reflection, the infrared receiving tube outputs a low level, the comparator outputs a high level, the drive transistor is turned on, the buzzer establishes a voltage difference, and starts to sound an alarm.

The part above the balloon of the urinary catheter 5 is provided with a scale layer, and the scale value is in the range of 0-15CM. Even if the audible alarm fails, it is possible to find out if the tube is out of line by observing the scale.

The top end of the balloon filling head 1 is provided with a one-way valve that can only be opened inward. At the inlet of the balloon, there is also a one-way valve that can only be opened inwards to prevent the balloon from shrinking and causing the tube to fall off.

Both the balloon irrigation head 1 and the flushing connector 3 are needle-free closed connectors. It can be directly matched with the needleless airtight joint for infusion flushing or injection of liquid into the balloon, and the urinary tube joint can be directly connected to the urine bag, or discharged.

Operation process: Before inserting the catheter 5, sterilize the insertion site, open the outer package of the catheter 5, take out the urinary catheter, use a needle-free connector syringe to confirm whether the balloon 8 can expand and contract, and connect the urinary catheter connector. Urine bag or waste bucket, carefully insert the catheter 5 into the bladder through the urethral opening, and after the urine flows out of the catheter 5, insert the catheter 5 into a certain distance, so that the balloon 8 completely enters the bladder, and then Use a syringe with a needleless sealed joint to inject a prescribed volume of normal saline into the balloon 8 through the balloon infusion head 1. At this time, the balloon should be opened under pressure, and gently pull the catheter 5 to make the inflated balloon 8 get stuck in the bladder. Then slowly pull out the syringe, at this time the balloon valve is closed, the balloon 8 is kept inflated, and the urinary catheter 5 is fixed in the bladder. When the catheter 5 is displaced or close to coming out, the photoelectric sensor 94 converts the light signal into an electrical signal, and controls the buzzer 92 to give a warning. You can also observe whether the catheter 5 is If displacement occurs, when performing bladder cleaning, pull out the flushing plug 4, and inject the flushing fluid into the bladder for cleaning through the flushing connector 3. Before pulling out the urinary catheter 5, the liquid in the balloon 8 needs to be drawn out with a needle-free syringe , after the balloon is contracted, then pull out the catheter 5. By setting a scale at the front end of the catheter 5, it can be judged by the scale whether the catheter is displaced or close to prolapse. The balloon 8 is designed in a disc shape to reduce The volume, the folded diameter is very small before the bladder is placed, and the normal saline is injected after the placement. The disc-shaped balloon 8 is stretched out like a wheel, and it is not easy to come out. It is automatically judged at the critical position that when the urinary catheter is displaced or close to coming out, the photoelectric sensor 94 converts the light signal into an electrical signal, and controls the buzzer 92 to give an alarm.
