Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a novel indwelling urinary catheter capable of continuously detecting bladder pressure. Background Art

[0002] Critically ill patients in the intensive care unit often suffer from severe complications, trauma and stress reactions. They lose consciousness and are unable to complain of the urge to urinate, requiring long-term indwelling catheterization. However, as the duration of the catheter increases, complications also increase. The most common are decreased bladder function and catheter-related urinary tract infection. Therefore, dynamic monitoring of intra-bladder pressure is particularly important.

[0003] The existing methods for monitoring bladder pressure during use of indwelling urinary catheters are mainly as follows:

[0004] 1. Connect the urinary catheter to the tee, and the tee is connected to the water injection soft valve, the liquid outlet pipe and the detection tube respectively. A pressure sensor is set inside the detection tube;

[0005] 2. Before measuring, empty the bladder first, then close the outlet tube and the urine bag at one end of the outlet tube;

[0006] 3. Inject 15-20 ml of saline into the bladder;

[0007] 4. When measuring, the monitor is reset to zero, the apex of the patient's pubic symphysis is taken as the zero point, and the pressure value is read at the end of exhalation. The measured value is the bladder pressure. Measuring bladder pressure can reflect the capacity of the bladder during the urine storage period and the various responses of the bladder to the filling period. The normal bladder capacity should be between 300 ml and 500 ml;

[0008] During the measurement process, in order to avoid mutual interference between the water injection soft valve, the liquid outlet pipe and the detection tube, which may cause backflow and affect the test results, it is necessary to block the unnecessary tube body with a plug. However, the blockage of the plug is subjective and prone to leakage, which may affect the test results of the bladder pressure.

[0009] In view of this, the present utility model is proposed. Utility Model Content

[0031] When an indwelling urinary catheter is used, the water injection soft valve 102, the liquid outlet tube 103 and the detection tube 104 are switched in sequence through the conversion component to communicate with the tube body 101 and perform different operations. During the switching process, the inner side of the unused tube body is automatically blocked by the ball 302, and manual blocking control is no longer required, thereby reducing the occurrence of the phenomenon that the bladder pressure detection result is affected by missed blocking.

[0032] The conversion assembly includes a spherical groove 301 provided inside the mounting plate 2, and one end of the water injection soft valve 102, the liquid outlet pipe 103 and the detection pipe 104 are connected to the inside of the spherical groove 301.

The sphere 302 is provided with a first through groove 303, and the first through groove 303 is connected to the inside of one end of the pipe body 101. The sphere 302 is provided with a through groove for connecting with the water injection soft valve 102, the liquid outlet pipe 103 and the detection pipe 104.

[0033] A driving shaft 4 for rotating the sphere 302 is rotatably connected to the mounting plate 2 , one end of the driving shaft 4 is fixed to the sphere 302 , and a limiting component for limiting the driving shaft 4 after rotation is arranged on the outer side of the mounting plate 2 .

[0034] The limiting assembly includes an installation box 501 fixed on the outside of the installation disk 2, a limiting disk 502 is fixed on the side wall of the driving shaft 4 located inside the installation box 501, and three groups of C-shaped limiting grooves 503 arranged in a circular array are opened on the outside of the limiting disk 502.

After the driving shaft 4 switches to rotate, the limit block 504 is pushed to reset through the spring 6 and is offset against the C-shaped limit groove 503 at the corresponding position. Through the offset action between the limit block 504 and the C-shaped limit groove 503, the driving shaft 4 after the rotation switching is offset and limited, which facilitates the precise switching of the driving shaft 4 while assisting the driving shaft 4 to maintain the switched state, further improving the switching effect and stability of the switching component.

[0035] The elastic member is a plurality of springs 6 installed inside the installation box 501 , and one end of the spring 6 is connected to the limit block 504 ; the limit block 504 can be squeezed and pushed by the spring 6 .

[0037] When the indwelling urinary catheter is used, the front end of the tube body 101 is inserted into the patient's bladder. After the insertion is completed, physiological saline is injected into the airbag 105 using the water injection soft valve 102 to expand the airbag 105. The expanded airbag 105 prevents the inserted tube body 101 from falling off. After the insertion of the tube body 101 is completed, one end of the liquid outlet tube 103 is connected to an external urine bag, and urine produced in the patient's bladder is discharged outward through the tube body 101 and the liquid outlet tube 103.

In the process of the rotation of the ball 302, the second through groove 304 is communicated with the water injection soft valve 102, the liquid outlet pipe 103 and the detection tube 104 in sequence. In the process of communication, the water injection soft valve 102, the liquid outlet pipe 103 and the detection tube 104 are switched in sequence to communicate with the tube body 101 through the communication effect of the first through groove 303 and the tube body 101, and different operations are performed. In the process of switching, the inner side of the pipe of the unused tube body is automatically blocked by the ball 302, and manual blocking control is no longer required, thereby reducing the occurrence of the phenomenon that the detection result of bladder pressure is affected by leakage blocking. In addition, the continuous switching of the water injection soft valve 102, the liquid outlet pipe 103 and the detection tube 104 facilitates the sustainable use of the indwelling urinary catheter.

[0039] In the process of switching the water injection soft valve 102, the liquid outlet pipe 103 and the detection tube 104 through the rotation of the driving shaft 4, as the driving shaft 4 rotates, the limit plate 502 is driven to rotate. During the rotation of the limit plate 502, the limit block 504 is pushed to contract under force. After the driving shaft 4 switches to rotate, the limit block 504 is pushed to reset through the spring 6 and offset with the C-shaped limit groove 503 at the corresponding position. Through the offset action between the limit block 504 and the C-shaped limit groove 503, the driving shaft 4 after the rotation switching is offset and limited, which facilitates the precise switching of the driving shaft 4 while assisting the driving shaft 4 to maintain the switched state, further improving the switching effect and stability of the switching component.
