Description

Technical Field

[0001] The utility model relates to the technical field of urine detection, in particular to a drainage component for detecting urine bleeding in a urinary catheter. Background Art

[0002] A urinary catheter is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC). It can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is an air bag near the tip of the catheter to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine. The urine drainage bag generally refers to a transparent plastic bag at the end of the drainage tube that is used to collect the drained liquid after surgery, where bleeding or fluid accumulation deep inside the body or local surgery needs to be drained out using a tube.

[0003] The current urinary catheter is a tube that directly drains urine into a urine collection bag. However, after some urinary tract surgeries, nurses are required to strictly check the patient's bleeding status. The first step is to check the amount of urine with bleeding. However, after the wound is broken, the blood flows out with the urine and merges with the original urine. The doctor cannot judge the amount of urine, nor can he judge the amount of bleeding based on the color of the blood in the urine. In view of this, we propose a urine bleeding detection and drainage component in the urinary catheter. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a drainage component for detecting bleeding in urine in a urinary catheter, which solves the problems raised in the above background technology. To achieve the above purpose, the utility model is implemented through the following technical scheme: a drainage component for detecting bleeding in urine in a urinary catheter, comprising a drainage tube, a transparent through tube fixedly connected to the inside of the drainage tube, a ring-shaped blood oxygen detector installed on the surface of the transparent through tube, a valve core control device arranged inside the drainage tube, a urinary catheter connecting device arranged at the end of the drainage tube, and a post-detection cleaning device arranged on the drainage tube.

[0005] Preferably, a urine inlet, a urine outlet and a blood outlet are respectively provided inside the drainage tube, and the urine outlet and the blood outlet are symmetrically distributed with the center line of the urine inlet as the axis of symmetry.

[0006] Preferably, the valve core control device includes a connecting base, the surface of the connecting base is fixedly connected to the inside of the drainage tube, the end of the connecting base is rotatably connected to a valve ring, the surface of the valve ring is fixedly connected to a valve flap, and the valve ring passes through one end of the connecting base and is fixedly connected to a limited position frame.

[0007] Preferably, the valve core control device also includes a mounting ring, the surface of the mounting ring is fixedly connected to the annular blood oxygen detector, an electric push rod is installed inside the mounting ring, the output shaft of the electric push rod is connected to a coupling sleeve, and the surface of the coupling sleeve is fixedly connected to a sliding shaft.

[0008] Preferably, the surface of the valve flap is movably connected to the inside of the drainage tube, the end of the valve ring is rotationally connected to the inside of the drainage tube, and the inner wall of the limit frame is slidably connected to the surface of the sliding shaft.

[0009] Preferably, the post-detection cleaning device comprises a connecting seat, the inner wall of the connecting seat is fixedly connected to the surface of the drainage pipe, the interior of the connecting seat is fixedly connected to a nozzle, and the surface of the connecting seat is fixedly connected to a connecting pipe.

[0010] Preferably, the catheter connection device comprises a rotating sleeve, the interior of the rotating sleeve is rotatably connected to the end of the drainage tube, and the two ends of the rotating sleeve are respectively fixedly connected with a rotating handle and a screw sleeve.

[0011] It can be seen from the above technical solutions that the catheter urine bleeding detection and drainage assembly provided in the embodiments of this specification has at least the following beneficial effects:

[0012] (1) The utility model detects the blood oxygen of urine flowing in the three-way drainage tube through an annular blood oxygen detector, uses the detected information to control the operation of the valve core control device, and controls the rotation angle of the valve core to achieve the effect of switching the blocking state of the urine outlet and the blood outlet, thereby achieving the effect of diverting urine, so that bloody urine can automatically enter a separate urine bag for storage, thereby facilitating medical personnel to perform separate detection and judgment on bloody urine, and thereby facilitating accurate evaluation of the patient's blood volume.

[0013] (2) After the urine is diverted, the utility model uses a post-detection cleaning device to control the water pipe to absorb water through a water pump. The water enters the connecting seat through the connecting pipe and is evenly sprayed into the interior of the drainage tube through various nozzles, thereby achieving the effect of flushing the interior thereof, thereby avoiding the effect of residual residue affecting the subsequent detection of the annular blood oxygen detector, automatically cleaning the interior of the drainage tube in a timely manner, and improving the accuracy of blood monitoring during urine monitoring.

By controlling the rotation angle of the valve disc 43, the effect of switching the blocking state of the urine outlet 12 and the blood outlet 13 is achieved, and then the effect of diverting urine is achieved, so that the bloody urine can automatically enter the separate blood urine bag 73 for storage, and then it is convenient for medical staff to separately detect and judge the bloody urine, and then it is convenient to accurately evaluate the patient's blood volume.

[0027] In addition, the surface of the valve flap 43 is movably connected to the inside of the drainage tube 1 , the end of the valve ring 42 is rotationally connected to the inside of the drainage tube 1 , and the inner wall of the limit frame 44 is slidably connected to the surface of the sliding shaft 48 .

[0028] Example 2
