Referring to fig. 1 and 3, the present invention provides a urinary catheter, which includes a flow rate measuring device 1, a drainage tube 2 and a connector 3; a drainage pipeline 31 is arranged in the connecting piece 3, and the drainage pipeline 31 is communicated with the rear end of the drainage pipeline 2; the flow rate measuring device 1 is disposed on the connecting member 3, communicates with the drain line 31, and measures the flow rate of the fluid in the drain line. Before the use, connect the rear end at drainage tube 2 with connecting piece 3 earlier, then slowly insert the urethra of patient with the anterior of drainage tube 2, when the front end of drainage tube 2 got into the bladder, the urine will be discharged along drainage tube 2 under the pressure of bladder. Urine leaves the drainage tube 2 and enters the drainage tube 31 of the connecting piece 3, and the drainage port of the drainage tube 31 can be connected with a urine collection bag or other containers. When the urine passes through drain pipe 31, can show different numerical values along with the velocity of flow size on the velocity of flow survey device 1, medical personnel can judge urination speed according to the numerical value size, when urination speed was too fast, can inlay drainage tube 2 tightly in order to slow down urination speed, through the setting of velocity of flow survey device 1, can make medical personnel accurate judgement urination speed, improvement operating mass. Connecting piece 3 can be dismantled with drainage tube 2 and be connected, but reuse reduces use cost after the cleaning and disinfection, and drainage tube 2 is the disposable consumptive material of putting into the human body, and the use is abandoned promptly. In one embodiment, the front end of the drainage pipeline 2 is an arc surface, a plurality of through holes are formed in the arc surface, and the through holes are used for urine to enter the drainage pipeline 2. The cambered surface can reduce the stimulation to the urethra and the bladder of the patient when the drainage pipeline 2 is inserted.

Referring to fig. 2, in one embodiment, the flow rate measuring device 1 includes an air bag 11, a graduated tube 12 and a slide block 13; the air bag 11 is connected with the liquid drainage pipeline 31 through the graduated tube 12; the slider 13 is arranged in the graduated tube 12, and the edge of the slider is connected with the inner wall of the graduated tube 12 in a sliding manner. Specifically, the graduated tube 12 is a transparent graduated tube 12, and the position of the slider 13 in the graduated tube 12 can be observed from the outside. The sliding block 13 has a sealing function, and can prevent urine from entering the air bag 11 through the graduated tube 12. Further, the inner diameter of the drainage pipeline 31 is smaller than the inner diameter of the drainage pipeline 2, the outlet end of the drainage pipeline is gradually narrowed, when urine passes through, part of urine flows into the transparent graduated tube 12, and forms a pushing force on the sliding block 13, the position of the sliding block 13 on the graduated tube 12 is affected by the pressure of the air bag 11 and the pressure of the drainage pipeline 31, when the flow rate of the urine reaches a certain degree, part of urine is shunted to the graduated tube 12 when passing through the drainage pipeline 31 and pushes the sliding block 13 to the air bag 11, at the moment, the pressure in the air bag 11 rises, and when the urine gradually decreases, the sliding block 13 is pushed back to the initial position by the pressure in the air bag 11. In the moving process of the slide block 13, the scale corresponding to the slide block 13 is the urine flow rate.

Referring to fig. 1 and 3, in one embodiment, the catheter further comprises a balloon 21 and a water injection conduit 22; the balloon 21 is communicated with the front end of the water injection pipeline 22; the front end of the drainage pipeline 2 passes through the balloon 21; the connecting piece 3 is further provided with a first joint 32, and the first joint 32 is detachably connected with the rear end of the water injection pipeline 22. In practical use, after the drainage pipeline 2 is inserted into the bladder, the syringe is connected with the first connector 32, then sterile normal saline is injected, the sterile normal saline enters the balloon 21 through the water injection pipeline 22, and the balloon 21 is inflated after the sterile normal saline is injected, so that the catheter cannot be drawn out and is fixed in the bladder. When the physiological saline is injected, the injection amount is strictly controlled, otherwise, the balloon 21 is inflated. After the saline injection is completed, the syringe can be pulled out from the first connector 32. When the drainage tube 2 needs to be pulled out from the bladder, the sterile normal saline of the balloon 21 needs to be extracted by using the syringe, and then the drainage tube 2 needs to be pulled out slowly so as to avoid damaging the urethra.

In one embodiment, the first connector 32 is a needleless connector. The needleless connector can prevent the needle of the injector from being inserted through the wall of the drainage pipeline 2 to cause the drainage pipeline 2 to be damaged, thereby preventing urine leakage caused by the damage of the drainage pipeline 2 and reducing the spreading risk of infectious diseases such as AIDS and the like.

Referring to fig. 1 and 3, in one embodiment, the catheter further comprises a cleaning solution conduit 23, and a front end of the cleaning solution conduit 23 passes through the balloon 21; the connecting piece 3 is further provided with a second joint 33, and the second joint 33 is detachably connected with the rear end of the cleaning liquid pipeline 23. For patients with bladder infection and other diseases, the bladder needs to be flushed by injecting normal saline or injected with liquid medicine, and the flushing liquid channel is used for conveying sterile normal saline or liquid medicine into the bladder. When in use, the syringe filled with the normal saline or the liquid medicine is connected with the second connector 33, and then the normal saline or the liquid medicine is injected. The injection speed needs to be noticed when the physiological saline or the liquid medicine is injected, and the injection speed cannot be too fast, so that the bladder is prevented from being excessively stimulated. In addition, the injected liquid can not be too much, so that the phenomenon that the bladder is excessively inflated due to untimely liquid discharge is avoided.

Referring to fig. 3, in one embodiment, the front ends of the drainage pipe 31, the first joint 32 and the second joint 33 are provided with connection plugs 34. To the patient of catheterization of keeping somewhere for a long time, need regularly change the catheter to avoid appearing infecting, the setting up of connecting spigot 34 makes the installation and the dismantlement of connecting piece 3 and drainage pipeline 2 more convenient. After the use, the catheter only needs to be replaced and placed into the drainage pipeline 2 part of the human body, and the connecting piece 3 can be continuously used after cleaning and disinfection, so that the consumption of materials is reduced, and the economic burden of a patient is reduced.

In one embodiment, the connection spigot 34 is provided with anti-slip threads. The anti-slip pattern is used for strengthening the connection between the drainage pipeline 2 and the connecting piece 3, and the situations of urine leakage and the like caused by slippage in the use process are avoided.

It should be understood that the technical solutions and the inventive concepts according to the present invention may be equally replaced or changed by those skilled in the art, and all such changes or substitutions should fall within the protection scope of the appended claims.
