Obviously, the described embodiment is only a part of the embodiment of the present application, not all of the embodiments.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. Example 1
[0026] For easier understanding, see Figure 1-Figure 3 This embodiment provides a urethral flushing device, including a tube body 3, which is vertically arranged and has a main body shape of a cylinder.
[0027] like Figure 1 As shown, the upper end of the tube body 3 is the head end, the lower end of the tube body 3 is the tail end, the head end of the tube body 3 is connected to a tube head 6, the shape of the tube head 6 is conical, and the tip of the tube head 6 faces upward. A plurality of liquid outlets 5 and a plurality of liquid collecting ports 4 are provided on the outer wall of the tube body 3, the liquid outlets 5 are arranged in sequence up and down along the axial direction (vertical direction) of the tube body 3, and the liquid collecting ports 4 are also arranged in sequence up and down along the axial direction (vertical direction) of the tube body 3, and the liquid collecting ports 4 are arranged near the lower end of the liquid outlet 5, and a certain gap is reserved between the liquid outlet 5 and the liquid collecting ports 4.
[0028] A liquid inlet pipe 2 and a liquid collecting pipe 8 are provided inside the tube body 3. The diameter of the tube body 3 is significantly smaller than the diameter of the urethra. One end of the liquid inlet pipe 2 is provided inside the tube body 3 and is connected to each liquid outlet 5 in sequence. The other end of the liquid inlet pipe 2 extends to the outside of the tail end of the tube body 3 and is connected to a liquid storage bottle 1. The liquid storage bottle 1 is also connected to an inflation mechanism 11. The liquid storage bottle 1 is filled with a cleaning liquid for cleaning the urethra. One end of the liquid collecting pipe 8 is provided inside the tube body 3 and is connected to all the liquid collecting ports 4. The other end of the liquid collecting pipe 8 extends to the outside of the tail end of the tube body 3 and is connected to a liquid collecting bottle 7. The liquid collecting bottle 7 is also connected to a negative pressure mechanism 12. The liquid collecting pipe 8 is used to collect liquid discharged from the urethra.
[0029] The working process of a urethral flushing device of this embodiment is as follows: the medical staff inserts the tube body 3 into the patient's urethra from bottom to top, and then inflates the liquid storage bottle 1 through the inflation mechanism 11, so that the internal air pressure of the liquid storage bottle 1 increases, and the internal air pressure pushes the cleaning liquid inside the liquid storage bottle 1 into the liquid inlet pipe 2, and the cleaning liquid flows from the liquid inlet pipe 2 to each liquid outlet 5, and then flows from the liquid outlet 5 to the urethra to flush the urethra. The medical staff then starts the negative pressure mechanism 12 to work, and the negative pressure mechanism 12 extracts the air from the liquid collection bottle 7, so that the air pressure in the liquid collection bottle 7 is reduced, and the air in the liquid collection pipe 8 is sucked into the liquid collection bottle 7, and the air pressure in the liquid collection pipe 8 decreases, and the liquid collection pipe 8 sucks the cleaning liquid flowing out of the liquid outlet 5 through the liquid collection port 4, and then transports it to the liquid collection bottle 7. Repeat the above operation process until the urethra is cleaned, and finally the tube body 3 is extracted from the urethra.
[0030] It should be noted that the existing urethral flushing method is to insert a syringe into the urethra and inject the cleaning liquid into the urethra. Because the urethra is narrow and long, the cleaning liquid is mainly concentrated at the outlet of the tip of the syringe head. A large amount of cleaning liquid gathers at the outlet of the tip of the syringe head, and the cleaning liquid in other parts of the urethra is relatively less. The flushing effect of the cleaning liquid gathering in the urethra is better, and the flushing effect of the cleaning liquid in the urethra is poor, resulting in uneven flushing of the urethra. In the working process of the urethral flushing device of the present embodiment, the cleaning liquid flows out from the multiple liquid outlets 5 arranged along the axial interval on the side wall of the tube body 3, and can flow into the narrow and long urethra more evenly, avoiding the problem of uneven distribution of the cleaning liquid in the urethra, so that the cleaning liquid flushes the urethra more evenly. In addition, in the existing urethral flushing method, it is necessary to first insert the syringe into the urethra for injection and flushing, and then withdraw the syringe after flushing, and then insert the drainage tube into the urethra for drainage. It is necessary to insert the device into the urethra or withdraw it from the urethra for many times, which causes more pain to the patient. During the operation of the urethral flushing device of the present embodiment, it is only necessary to insert the tube body 3 into the urethra, and the cleaning liquid can be injected into the urethra through the liquid inlet tube 2 and the liquid outlet 5 for flushing and cleaning, and the cleaning liquid can be extracted from the urethra through the liquid collecting tube 8 and the liquid collecting port 4. In other words, it is only necessary to insert the device into the urethra once to complete flushing and drainage, thereby reducing the pain of the patient.
[0031] In one embodiment, Figure 2 As shown, four liquid outlets 5 are arranged at the same height and circumferential intervals along the outer wall of the tube body 3. The four liquid outlets 5 are symmetrically arranged about the axis of the tube body 3, and the line connecting two liquid outlets 5 is perpendicular to each other. Figure 3 As shown, four liquid collecting ports 4 are arranged at the same height and circumferential intervals along the outer wall of the tube body 3, and the four liquid collecting ports 4 are arranged symmetrically about the axis of the tube body 3, and the connecting line between two relative liquid collecting ports 4 is perpendicular to each other. Such an arrangement can make the cleaning liquid flow out more evenly, and can be spread over the four sides of the tube body 3, front, back, left, and right, which helps to improve the uniformity of urethra cleaning.
[0032] Combination Figure 2 and Figure 3 As shown, the liquid collecting port 4 is arranged near the lower end of the liquid outlet 5, a gap is reserved between the liquid collecting port 4 and the liquid outlet 5, and the liquid outlet 5 and the liquid collecting port 4 are arranged in a staggered manner in the vertical direction. The liquid outlet 5 is arranged at the position facing the front side, the rear side, the right side, and the left side of the tube body 3, and the liquid collecting port 4 is arranged at the position of 45 degrees to the upper left, 45 degrees to the upper right, 45 degrees to the lower left, and 45 degrees to the lower right of the tube body 3. When the cleaning liquid flows out of the liquid outlet 5, the urethra is cleaned, and then a negative pressure is generated in the liquid collecting port 4 to suck in the cleaning liquid. The flow direction of the cleaning liquid outside the tube body 3 is obliquely downward. This arrangement can prevent the cleaning liquid from flowing vertically downward, causing the area where the cleaning liquid flows to be too concentrated directly below the liquid outlet 5.
[0033] like Figure 2 As shown, the liquid inlet pipe 2 is arranged on the axis inside the tube body 3, and the liquid inlet pipe 2 is connected to a plurality of first connecting pipes 9 along the radial extension, and the two ends of each first connecting pipe 9 are respectively connected to the liquid inlet pipe 2 and the liquid outlet 5, and the cleaning liquid flows into the first connecting pipe 9 through the liquid inlet pipe 2 and then flows out from the liquid outlet 5. Figure 3 As shown, the liquid collecting pipe 8 is arranged near the inner wall of the tube body 3, and an annular second connecting pipe 10 is arranged along the circumference of the inner wall of the tube body 3. The liquid collecting pipe 8 is connected with the second connecting pipe 10, and the second connecting pipe 10 is connected with the liquid collecting port 4 at the same height. The purpose of arranging the liquid inlet pipe 2 and the liquid collecting pipe 8 as described above is to stagger the two pipes, prevent the positions of the two pipes from conflicting, reduce the number of bent parts, and improve the smoothness of the flow of liquid inside the pipeline.
[0034] like Figure 2 As shown, the outlet 5 is arranged with a gradually decreasing diameter from the inside to the outside. This arrangement can make the cleaning liquid have a relatively large pressure when it flows out of the outlet 5, so as to flush the urethra and clean the urethra.
[0035] like Figure 3 As shown, the diameter of the liquid collecting port 4 is gradually widened from the inside to the outside. This is arranged to expand the outer opening of the liquid collecting port 4 so that the liquid in the urethra can be sucked into the liquid collecting port 4 more easily.
[0036] like Figure 1 As shown, the upper end of the liquid storage bottle 1 is connected to the gas charging mechanism 11, and the lower end of the liquid storage bottle 1 is connected to the liquid inlet pipe 2. When the liquid storage bottle 1 is charged with gas through the gas charging mechanism 11, the air pressure inside the liquid storage bottle 1 increases, and the cleaning liquid inside the liquid storage bottle 1 is simultaneously subjected to the effects of gravity and air pressure, so it is relatively easy to squeeze the cleaning liquid out from the bottom of the liquid storage bottle 1.
[0037] One side of the upper end of the liquid collecting bottle 7 is connected to the negative pressure mechanism 12, and the other side of the upper end of the liquid collecting bottle 7 is connected to the liquid collecting pipe 8. This arrangement can prevent the liquid from blocking the connection between the liquid collecting bottle 7 and the liquid collecting pipe 8, and can also prevent the liquid from flowing into the negative pressure mechanism 12 to cause blockage.
[0038] Preferably, the inflation mechanism 11 is a push-type inflation airbag, and the medical staff can adjust the internal air pressure of the liquid storage bottle 1 by pressing the push-type inflation airbag. The negative pressure mechanism 12 is a negative pressure aspirator, and the medical staff can adjust the internal air pressure of the liquid collection bottle 7 by opening and closing the negative pressure aspirator.
[0039] Although the present invention has been described using the above preferred embodiments, it is not intended to limit the scope of protection of the present invention. Any person skilled in the art may make various changes and modifications to the above embodiments without departing from the spirit and scope of the present invention, and the changes and modifications still fall within the scope of protection of the present invention.
