Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a novel urinary catheter. Background Art

[0002] Urology is a hospital department that mainly diagnoses and treats diseases of the "surgical" part of the urinary system. It mainly treats various urinary diseases. After some patients have completed surgery, they are still in the recovery period and need to use a catheter to drain urine. The discharged urine is collected in a urine storage bag. After the urine in the urine storage bag has collected a certain volume, the medical staff or the accompanying personnel will pour the urine out of the urine storage bag. Generally, the urine is poured into a basin and then taken to the bathroom to be dumped. Generally, it is a collective ward. Pouring urine into a basin and taking it out makes the urine smell spread in the ward, affecting the ward environment, especially in the hot summer, making the ward air turbid. If there are pathogens in the urine, it is also likely to infect other people. When pouring urine, medical staff need to close the catheter, but closing the catheter requires the help of external tools, which is relatively too troublesome, and there is a possibility of urine leakage and dripping. For this reason, we have proposed a new type of catheter to solve the above problems. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 , the utility model provides an embodiment: a novel urinary catheter, comprising a urinary catheter 1;

[0020] An air bag 2 is arranged at the upper end of the urinary catheter 1, a connecting block 3 is arranged at the lower end of the urinary catheter 1, a urine storage tank 4 is movably installed at the lower end of the connecting block 3, a threaded groove 5 is arranged in the lower end of the connecting block 3, the upper end of the urine storage tank 4 is inserted in the threaded groove 5, a first through hole 6 is arranged in the upper end of the connecting block 3, a second through hole 7 is arranged in the lower end of the connecting block 3, the second through hole 7 is located at the upper end of the threaded groove 5, a sealing component is arranged in the connecting block 3, when the urine storage tank 4 is removed from the connecting block 3, the inner wall of the second through hole 7 is closed by the sealing component, thereby preventing urine in the urinary catheter 1 from dripping;

[0021] Furthermore, the sealing assembly includes an annular plate 8, which is arranged in the threaded groove 5. A plurality of connecting rods 9 are arranged in an annular shape on the upper side of the annular plate 8. A cover plate 10 is arranged on the upper end of the plurality of connecting rods 9. The cover plate 10 is located in the first through hole 6. A plurality of movable grooves 11 are arranged in an annular shape in the connecting block 3. Springs 12 are installed in the plurality of movable grooves 11. Baffles 13 are fixedly installed on the plurality of connecting rods 9. The plurality of baffles 13 are located in the upper ends of the plurality of movable grooves 11. Under the action of the restoring elastic force of the plurality of springs 12, the structure moves the annular plate 8, the plurality of connecting rods 9 and the cover plate 10 downward, so that the cover plate 10 closes the upper end opening of the second through hole 7, thereby sealing the inside of the connecting block 3.

[0022] Furthermore, the inner wall diameter of the first through hole 6 is larger than the inner wall diameter of the second through hole 7, and the first through hole 6 is located at the upper end of the second through hole 7. This structure enables urine to flow from the first through hole 6 into the second through hole 7 when the cover plate 10 moves upward and away from the opening of the second through hole 7, based on the diameters of the inner walls of the first through hole 6 and the second through hole 7, so that urine can be collected.

[0023] Furthermore, the outer wall of the lower end of the cover plate 10 is smaller than the outer wall of the upper end, and the diameter of the outer wall of the lower end of the cover plate 10 is the same as the diameter of the inner wall of the second through hole 7. This structure allows the lower end of the cover plate 10 to be inserted into the second through hole 7 according to the outer wall diameters of the upper and lower ends of the cover plate 10 and the inner wall diameter of the second through hole 7 to close and seal the opening of the second through hole 7, thereby preventing urine from leaking and dripping from the second through hole 7.

[0024] Furthermore, an annular protrusion is provided at the opening of the lower end of the second through hole 7, and the annular protrusion at the opening of the lower end of the second through hole 7 is inserted into the opening of the upper end of the urine storage tank 4. The outer wall of the annular protrusion at the opening of the lower end of the second through hole 7 has the same diameter as the inner wall of the opening of the upper end of the urine storage tank 4. According to the annular protrusion at the opening of the lower end of the second through hole 7, when the upper end of the urine storage tank 4 is inserted into the threaded groove 5, the annular protrusion is inserted into the upper end of the urine storage tank 4, thereby preventing urine from entering the gap between the upper end of the urine storage tank 4 and the threaded groove 5 and the annular plate 8.

[0025] Furthermore, two groups of hooks 14 are provided on the rear side of the urine storage tank 4. This structure uses the two groups of hooks 14 to hang the urine storage tank 4 on the edge of the hospital bed, making it easy to place the urine storage tank 4.

[0026] Working principle: When pouring the urine in the urine storage tank 4, Figure 3 and Figure 4 As shown, the urine storage tank 4 is twisted to take the upper end of the urine storage tank 4 out of the threaded groove 5. When the upper end of the urine storage tank 4 is taken out from the threaded groove 5, the multiple groups of baffles 13 and the multiple groups of connecting rods 9 are driven to slide upward under the action of the restorative force of the multiple springs 12. The multiple groups of connecting rods 9 slide downward to drive the annular plate 8 and the cover plate 10 to slide downward in the threaded groove 5 and the first through hole 6 respectively. The cover plate 10 slides downward to close the upper end opening of the second through hole 7, so that the urine in the urine storage tank 4 can be poured out. On the contrary, the urine storage tank 4 is installed on the connecting block 3, and the upper end of the urine storage tank 4 is inserted in the threaded groove 5 to push the annular plate 8, the multiple connecting rods 9 and the cover plate 10 upward. The multiple groups of cover plates 10 move upward and move from the upper end opening of the second through hole 7, and the urine in the catheter 1 flows into the urine storage tank 4 from the first through hole 6 and the second through hole 7. The above is the entire working principle of the utility model.

[0027] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
