DETAILED DESCRIPTION
[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] The present invention will be further described below in conjunction with the embodiments.
[0021] Example: A stone removal device for urology nursing, refer to the attached Figure 1-7 ,include: The collecting assembly 1 comprises a liquid collecting cylinder 11, a base 12 and a movable cover plate 13 slidably arranged on the liquid collecting cylinder 11. The liquid collecting cylinder 11 is arranged above the base 12, and the base 12 serves as a support. The liquid collecting cylinder 11 is provided with an opening for collecting urine. The movable cover plate 13 is slidably installed on the liquid collecting cylinder 11 to cover the opening to prevent odor. When sampling, the movable cover plate 13 is opened and the patient's urine is collected. The base 12 is provided with a receiving hopper 123 which is connected with the liquid collecting cylinder 11 and is used to collect stones and urine separately. The bottom of the liquid collecting cylinder 11 is provided with a movable sealing plate 112, and the movable sealing plate 112 is used to select and open the urine collecting hole and the stone collecting hole of the receiving hopper 123 to guide urine and stones to different directions; For details, please refer to the attached Figure 5 and attached Figure 7, a partition is provided on the receiving hopper 123, and the partition is used to divide the receiving hopper 123 into a urine collecting hole and a stone collecting hole, respectively guiding urine and gravel to different collecting and storing devices, and the width of the movable sealing plate 112 is greater than the urine collecting hole or the stone collecting hole on the receiving hopper 123. In the initial state, the movable sealing plate 112 abuts against the right side of the liquid collecting cylinder 11, and at the same time covers the urine collecting hole to open the stone collecting hole on the receiving hopper 123. After the screen 24 is turned over and urine is filtered, the movable sealing plate 112 abuts against the left side of the liquid collecting cylinder 11 after the screen 24 is moved, and the movable sealing plate moves and covers the stone collecting hole. When the urine collecting hole on the hopper 123 is opened, the urine is discharged, and the movable sealing plate 112 is slidably set on the liquid collecting cylinder 11, and the movable sealing plate 112 is provided with an elastically installed limiting convex strip 1121, and the limiting convex strip 1121 is used for the screen 24 to cooperate with the shifting groove 2401 when rotating to shift the movable sealing plate 112 to swing on the liquid collecting cylinder 11, thereby opening the urine collecting hole and closing the stone collecting hole or closing the urine collecting hole and opening the stone collecting hole. When the movable sealing plate 112 reaches the limit position, it will be resisted by the liquid collecting cylinder 11, and at this time, the screen 24 continues to rotate and disengages from the limiting convex strip 1121.
[0022] The stone removal component 2 is used for filtering and discharging stones. The stone removal component 2 includes a screen 24 rotatably arranged on the liquid collecting cylinder 11 and a rack 22 slidably arranged on the liquid collecting cylinder 11 and extending out. A gear 23 meshing with the rack 22 is arranged on the rotating shaft of the screen 24, and a foot pedal 21 is arranged at the bottom of the rack 22. The rack 22 is driven down by stepping on the foot pedal 21, thereby turning the gear 23 and the screen 24 to rotate, so as to realize the change of the state of the screen 24. A rotating connector 241 movably connected to the movable cover 13 is rotatably installed on the top of the screen 24. When the screen 24 rotates, the movable cover 13 is driven to move in the liquid collecting cylinder through the rotating connector 241. 11 slides on and opens the liquid collecting cylinder 11, thereby making it convenient for the patient to discharge urine into the liquid collecting cylinder 11; since the limiting convex strip 1121 is elastically installed on the movable sealing plate 112, a sliding groove 2401 cooperating with the movable sealing plate 112 is provided at the bottom of the screen 24, and the limiting convex strip 1121 will be squeezed to retract into the movable sealing plate 112 when the screen 24 rotates; when the limiting convex strip 1121 enters the sliding groove 2401, the screen 24 drives the movable sealing plate 112 to move; when the movable sealing plate 112 moves to the extreme position, the screen 24 continues to rotate, and the limiting convex strip 1121 is forced to retract, thereby realizing the separation of the screen 24 and the movable sealing plate 112.
[0023] Specifically, the screen 24 is composed of two groups of filter screens, and the angle between the two groups of filter screens is a, and 90°<a<180°, so that the screen 24 is in a horizontal state and covers the inlet on the liquid collecting cylinder 11 when the movable cover 13 is opened. When the movable cover 13 is closed, the screen 24 flips and tilts to facilitate guiding the gravel on the screen 24 to separate and fall.
[0024] Furthermore, a plurality of groups of protrusions 111 are provided on the inner wall of the liquid collecting barrel 11, and the plurality of groups of protrusions 111 are distributed on the inner wall of the liquid collecting barrel 11 in a circular array along the rotation axis of the screen 24. A guide rod 243 and a movable bar 242 slidably connected to the guide rod 243 are provided on the screen 24, and one end of the movable bar 242 away from the screen 24 presses against the inner wall of the liquid collecting barrel 11, and an elastic member is provided on the side of the movable bar 242 close to the guide rod 243.
[0025] When the foot pedal 21 is released and the screen 24 is reset, the screen 24 again moves the movable sealing plate 112 to open the stone collecting hole on the hopper 123, and the screen 24 is tilted to introduce the gravel into the stone collecting hole. When the screen 24 is reset, the movable bar 242 arranged on the screen 24 cooperates with the protrusion 111 on the liquid collecting cylinder 11 to vibrate the screen 24, which assists the discharge and fall of the gravel on the screen 24. A collecting box 15 for collecting gravel is slidably installed in the base 12.
[0026] In addition, it also includes a cleaning mechanism 14 for cleaning the liquid collecting cylinder 11. The cleaning mechanism 14 includes a compressed water tank 145 arranged in the base 12 and an extrusion block 146 slidably installed in the base 12. When the foot pedal 21 descends, it pushes the extrusion block 146 to squeeze the compressed water tank 145. A water pipe 141 is provided on the extrusion block 146, and a nozzle 143 is provided at the discharge end of the water pipe 141. The nozzle 143 is arranged on the liquid collecting cylinder 11, and the spraying direction of the nozzle 143 is toward the screen 24. When the foot pedal 21 is stepped on and descended by the user, it will push the extrusion block 146 to move toward the compressed water tank 145, thereby squeezing out the liquid in the compressed water tank 145 and spraying it through the nozzle 143 to rinse the liquid collecting cylinder 11 and the screen 24 inside the liquid collecting cylinder 11.
[0027] Among them, an elastic reset structure is provided in the compressed water tank 145. After the compressed water tank 145 squeezes out the internal liquid, the internal elastic reset structure is reset and liquid is extracted from the outside to replenish the internal liquid of the compressed water tank 145.
[0028] In addition, an expansion ball 142 is provided on the water supply pipe 141, and a one-way valve is installed at the liquid inlet end and the liquid discharge end of the squeezing block 146 respectively. When the compression water tank 145 is pressurized, the liquid is squeezed into the expansion ball 142. At this time, the expansion ball 142 stores water and expands. After the squeezing of the compression water tank 145 is cancelled, the compression water tank 145 recovers and extracts the liquid from the external device, and the liquid in the expansion ball 142 will not flow back.
[0029] It is worth noting that a control valve 144 is provided between the water supply pipe 141 and the nozzle 143, and the control valve 144 extends toward the movable cover plate 13. After the movable cover plate 13 moves toward the control valve 144, the control valve 144 is toggled to close, and after the movable cover plate 13 is separated from the control valve 144, it is opened. By setting the control valve 144, when the movable cover plate 13 is opened, the control valve 144 will be squeezed. At this time, even if the water stored in the expansion ball 142 expands, water will not be sprayed out from the nozzle 143. Only when the movable cover plate 13 is closed and away from the control valve 144, the nozzle 143 will spray water to clean the screen 24, that is, during the resetting process of the screen 24, the nozzle 143 sprays water toward the screen 24 to clean it and at the same time washes down the gravel attached to the screen 24, so that the gravel on the screen 24 is cleaned more fully.
[0030] Working principle: the patient steps on the foot pedal 21 to descend, the foot pedal 21 drives the rack 22 to descend and cooperates with the gear 23 to drive the screen 24 to flip clockwise, at this time, the rotating connector 241 on the screen 24 drives the movable cover 13 to slide on the liquid collecting cylinder 11 and open, and at the same time the screen 24 covers the inlet of the liquid collecting cylinder 11, and the patient introduces urine into the liquid collecting cylinder 11 and filters it through the screen 24. At this time, because the screen 24 rotates clockwise, it moves the movable sealing plate 112 to open it. The urine collecting hole on the hopper 123 is opened, and the urine is discharged through the urine collecting hole after being filtered by the screen 24. At the same time, the foot pedal 21 cooperates with the squeezing block 146 to squeeze the compression water tank 145, and squeeze the cleaning liquid into the expansion ball 142. Since the squeezing control valve 144 blocks the nozzle 143 when the movable cover 13 is opened, the nozzle 143 cannot spray the cleaning liquid. After the patient's urine is discharged, the foot pedal 21 is released, the compression water tank 145 is reset and cooperates with the squeezing block 146 to drive the foot pedal 21 to reset. The gear 142 is then rotated to the left of the hopper 123 and the movable sealing plate 112 is moved to the right of the hopper 123. The movable bar 242 provided on the sieve 24 cooperates with the protrusion 111 in the liquid collecting cylinder 11 to vibrate the sieve 24 intermittently to assist in the collection of the gravel. At the same time, when the movable cover 13 is reset, the squeezing of the control valve 144 is cancelled. At this time, the nozzle 143 is opened, the expansion ball 142 contracts and sprays liquid onto the sieve 24 to assist in flushing the gravel on the sieve 24, further improving the gravel removal effect, ensuring more sufficient gravel collection, and preventing gravel from being left on the sieve 24, which affects the mixing of the gravel sample obtained by subsequent patients with the gravel sample remaining from the last user, resulting in inaccurate sample detection.
[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
