[0004] Common drainage devices on the current market generally face the problems that their structures are relatively simple and functions are relatively single. And when doctors are treating, they need to perform multiple drainages and then clean and guide the affected area. The current devices are relatively cumbersome and complex to operate during use. At the same time, it is also necessary to collect the drainage fluid multiple times to observe the color of the drainage fluid in order to evaluate the treatment effect and timely detect complications. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a drug guiding and drainage device for clinical use to solve the problems existing in the above-mentioned background art.

[0006] The present invention provides the following technical solution: A drug guiding and drainage device for clinical use, including a device housing. Inside the device housing, a transparent sliding cylinder and a storage box are fixedly connected. A piston rod is movably connected to the center of the transparent sliding cylinder. An auxiliary transmission mechanism is movably connected to the side of the piston rod. Two first connecting pipes are fixedly connected to the bottom of the transparent sliding cylinder. A control turntable is provided at the bottom of the first connecting pipe. The control turntable is rotatably connected to the device housing. A second connecting pipe and a fifth connecting pipe are fixedly connected to the bottom of the control turntable. A control component is fixedly connected to the bottom of the second connecting pipe. A third connecting pipe and a fourth connecting pipe are fixedly connected to the bottom of the control component. The third connecting pipe, the fourth connecting pipe, and the fifth connecting pipe are all fixedly connected to the storage box.

[0007] The auxiliary transmission mechanism includes a support rod. A first gear, an upper connector, a lower connector, and a second gear are rotatably connected to the support rod. A connecting plate is fixedly connected to the bottom of the support rod. A movable block is fixedly connected to the bottom of the connecting plate. The side of the movable block is movably connected to a turntable. An activity groove is provided on the turntable. The movable block is arranged inside the activity groove.

[0008] During the use process, the cleaning liquid guide pipe is inserted into the affected area. During the process of pulling and pushing the piston rod, the liquid extraction and flushing of the affected area are realized through the adjustment of the auxiliary transmission mechanism. At the same time, the fourth gear and the waste liquid collection box can be driven by the auxiliary transmission mechanism to rotate, and the liquid extracted each time is collected into different chambers on the waste liquid collection box. After the liquid extraction and flushing are completed, the medicine is conveyed to the affected area through the medicine outlet pipe by pressing the piston rod.

[0009] Further, a fixing rod is provided between the upper connector and the lower connector. The fixing rod is fixedly connected to the support rod. The upper connector and the lower connector have the same structure and are placed in a staggered manner. A first belt pulley is fixedly connected to the side of the turntable. A belt is provided on the first belt pulley. Another first belt pulley is provided at the other end of the belt. The second belt pulley and the first belt pulley are driven by the belt. A third gear is meshed and connected to the side of the first belt pulley. A transmission gear is provided on the side of the control turntable. A transmission rod is fixedly connected to the top of the transmission gear. The transmission rod is simultaneously meshed and connected to the first gear and the second gear.

[0010] Further, three through holes are provided on the control turntable. The included angle between the two sides of the transmission gear is sixty degrees. The transmission gear can be meshed with the control turntable during the rotational movement process. The activity groove provided on the turntable is composed of a vertical groove and a curved groove. When the movable block moves up and down in the vertical groove, the turntable does not move. When the movable block moves along the curved groove, the turntable will be driven to rotate.

[0011] Pull the piston rod upward. At this time, the piston rod and the auxiliary transmission mechanism are clamped together by the fixed block and the movable buckle. The piston rod drives the support rod, the connecting plate and the movable block to move upward. The support rod drives the fixed rod to move upward. The fixed rod contacts the upper connector on the support rod. Since the movable block at the bottom of the support rod is stuck inside the movable groove on the turntable, the support rod can only move in the vertical direction. The fixed rod moves at the teeth of the upper connector, driving the upper connector and the first gear to rotate. The first gear drives the lower connector and the second gear at the bottom to rotate through the transmission rod. At the same time, the transmission rod drives the transmission gear at the bottom to rotate; when the side connecting block on the piston rod moves to the inclined plane slider, the movable buckle disconnects from the fixed block, and the support rod moves downward by pushing, driving the fixed rod to move downward. The fixed rod drives the lower connector and the second gear to rotate. The second gear drives the transmission rod and the transmission gear to rotate.

[0012] After two presses and pulls, when pulling upward for the next time and the side connecting block moves to the position of the inclined plane slider, the movable buckle releases the fixed block, causing the auxiliary transmission mechanism to move downward, driving the transmission gear to rotate. At this time, the transmission gear will engage with the control turntable and drive the control turntable to rotate during the rotation process. Initially, the first connecting pipe connected to the second connecting pipe will be at the through hole on the control turntable, and the other first connecting pipe will be closed by the control turntable. After the control turntable rotates, the first connecting pipe connected to the second connecting pipe is closed by the control turntable, and the first connecting pipe connected to the fifth connecting pipe is connected to the first connecting pipe through the through hole. Pressing downward again can transport the liquid medicine inside the medicine storage box to the medicine outlet pipe.

[0013] Further, the transparent sliding cylinder includes an outer cylinder shell, and an inclined plane slider is fixedly connected inside the outer cylinder shell. The bottom of the inclined plane slider is movably connected with a telescopic rod.

[0014] Further, a fixed component is movably connected to the piston rod. The fixed component includes a side connecting block. The side connecting block is arranged outside the telescopic rod and is movably connected with the telescopic rod. A spring damping device and a connecting slider are fixedly connected to the side of the side connecting block. The spring damping device is sleeved on the connecting slider. The other side of the spring damping device is fixedly connected to the piston rod. A slider is movably connected to the side of the connecting slider. A fixing plate is fixedly connected to the top of the slider. A movable plate is rotatably connected to the fixing plate. A spring is rotatably connected to the other side of the movable plate. A movable buckle is fixedly connected to the side of the spring. A limiting rod is fixedly connected to the side of the movable buckle. The spring is sleeved on the limiting rod. The movable buckle is movably connected with the fixed block.

[0015] During use, the fixing component moves along with the piston rod. When the piston rod moves upward, the auxiliary transmission mechanism and the piston rod are fixed together through the fixed block and the movable buckle. The side connecting block slides upward on the telescopic rod. When the piston rod reaches the highest point, the side connecting block moves to the inclined plane slider, causing the side connecting block to move outward. The side connecting block drives the connecting slider to move outward, and the connecting slider pushes the slider upward, driving the bottom of the fixed plate and the movable plate to move upward. When the top of the movable plate moves upward, it unfolds outward, driving the movable buckle to move outward, releasing the fixing relationship between the fixed block and the movable buckle. When the piston rod moves downward, the side connecting block moves from the inclined plane slider to the telescopic rod, and the side connecting block contracts inward, causing the movable buckle to move inward. When the piston rod reaches the lowest point, the fixed block is clamped by the movable buckle, and the movable buckle and the fixed block are fixed again.

[0016] During the process of liquid export and injection, the fixing component, the auxiliary transmission mechanism, and the piston rod can, when exporting, first rotate the turntable and the second pulley, drive the waste liquid collection box to rotate, and then export the waste liquid to the waste liquid collection box through the piston rod, enabling the fractional collection of waste liquid and facilitating the observation of the cleaning state of the cleaning liquid and the tissue state at the fixing point of the cleaning liquid diversion pipe.

[0017] Furthermore, a cleaning liquid diversion pipe and a drug export pipe are fixedly connected to the side of the storage box. Adjusting components are fixedly connected to both the cleaning liquid diversion pipe and the drug export pipe. The storage box includes a box body shell, and a drug storage box, a cleaning liquid storage box, and a collection box are provided on the box body shell. A waste liquid collection box is rotatably connected inside the collection box, and a fourth gear is fixedly connected to the bottom of the waste liquid collection box. The cleaning liquid diversion pipe is a three-way pipe, with two ends respectively connected to the cleaning liquid storage box and the collection box, and the drug export pipe is connected to the box body shell.

[0018] Furthermore, the control component includes an external sleeve. A third connecting pipe and a fourth connecting pipe are fixedly connected to the bottom of the external sleeve. A central sleeve is movably connected inside the external sleeve. An air vent is provided at the bottom of the central sleeve. A spring damper is fixedly connected to the side of the central sleeve, and the side of the spring damper is fixedly connected to the external sleeve. A one-way valve is provided inside the fourth connecting pipe.

[0019] Furthermore, the adjusting component includes a movable ring. The bottom of the movable ring is movably connected to a fixed block. The side of the fixed block is movably connected to a current-limiting block. A fixed ring is provided at the bottom of the fixed block. The fixed ring is fixedly connected to the cleaning liquid diversion pipe and the drug export pipe. The cleaning liquid diversion pipe and the drug export pipe are threadedly connected to the movable ring. A limiting block is fixedly connected to the top of the fixed ring. A limiting slider is movably connected to the limiting block, and the current-limiting block and the limiting slider are fixedly connected.

[0021] 1. By providing an auxiliary transmission mechanism, through the adjustment of the auxiliary transmission mechanism, when the piston rod moves up and down, the housing of the box body, the medicine storage box and the cleaning liquid storage box can switch the on-off relationship with the transparent sliding cylinder. When in use, "liquid extraction - cleaning liquid injection - liquid extraction - secondary cleaning liquid injection - liquid extraction - medicine delivery" can be realized without adjusting the switch, and the operation is simpler.

Detailed implementation manners

[0032] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following embodiments are merely examples. A clinical drug guiding and drainage device related to the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0033] Refer to Figures 1 - 8, the present invention provides a clinical drug guiding and drainage device, which includes a device housing 1. Inside the device housing 1, a transparent sliding cylinder 4 and a storage box 3 are fixedly connected. A piston rod 6 is movably connected to the center of the transparent sliding cylinder 4, and an auxiliary transmission mechanism 5 is movably connected to the side of the piston rod 6. Two first connecting pipes 10 are fixedly connected to the bottom of the transparent sliding cylinder 4. A control turntable 11 is arranged at the bottom of the first connecting pipe 10. The control turntable 11 is rotatably connected to the device housing 1. A second connecting pipe 13 and a fifth connecting pipe 17 are fixedly connected to the bottom of the control turntable 11. A control component 14 is fixedly connected to the bottom of the second connecting pipe 13. A third connecting pipe 15 and a fourth connecting pipe 16 are fixedly connected to the bottom of the control component 14. The third connecting pipe 15, the fourth connecting pipe 16 and the fifth connecting pipe 17 are all fixedly connected to the storage box 3.

[0034] The auxiliary transmission mechanism 5 includes a support rod 501. A first gear 503, an upper connector 504, a lower connector 506 and a second gear 507 are rotatably connected to the support rod 501. A connecting plate 508 is fixedly connected to the bottom of the support rod 501. A movable block 510 is fixedly connected to the bottom of the connecting plate 508. The side of the movable block 510 is movably connected to a turntable 509. An activity groove is provided on the turntable 509, and the movable block 510 is arranged inside the activity groove.

[0035] In this embodiment, it should be specifically noted that: during the use process, the cleaning liquid guide pipe 8 is inserted into the affected area. During the process of pulling and pushing the piston rod 6, the liquid extraction and flushing of the affected area are realized through the adjustment of the auxiliary transmission mechanism 5. At the same time, the auxiliary transmission mechanism 5 can also drive the fourth gear 306 and the waste liquid collection box 305 to rotate, and collect the liquid extracted each time into different chambers on the waste liquid collection box 305. After the liquid extraction and flushing are completed, the drug is transported to the affected area through the drug export pipe 9 by pressing the piston rod 6.

[0036] The main difference between this embodiment and the prior art is that in this embodiment, an auxiliary transmission mechanism 5 and a control turntable 11 are used to control the pumping process. Specifically: when the piston rod 6 is pulled upward, at this time, the piston rod 6 and the auxiliary transmission mechanism 5 are clamped together by a fixed block 502 and a movable buckle 207. The piston rod 6 drives the support rod 501, the connecting plate 508 and the movable block 510 to move upward. The support rod 501 drives the fixed rod 505 to move upward. The fixed rod 505 contacts the upper connector 504 on the support rod 501. Since the movable block 510 at the bottom of the support rod 501 is stuck inside the movable groove on the turntable 509, the support rod 501 can only move in the vertical direction. The fixed rod 505 moves at the teeth of the upper connector 504, driving the upper connector 504 and the first gear 503 to rotate. The first gear 503 drives the lower connector 506 and the second gear 507 at the bottom to rotate through the transmission rod 515. At the same time, the transmission rod 515 drives the transmission gear 516 at the bottom to rotate; when the side connecting block 203 on the piston rod 6 moves to the inclined plane slider 402, the movable buckle 207 disconnects from the fixed block 502, and the support rod 501 drives the fixed rod 505 to move downward by pushing. The fixed rod 505 drives the lower connector 506 and the second gear 507 to rotate. The second gear 507 drives the transmission rod 515 and the transmission gear 516 to rotate. When the support rod 501 moves up and down, the fixed rod 505 will drive the first gear 503 and the lower connector 506 to rotate. The first gear 503 and the lower connector 506 drive the transmission rod 515 to rotate. The transmission gear 516 at the bottom of the transmission rod 515 drives the control turntable 11 to rotate during the rotation process, so that the first connecting pipe 10 initially connected to the second connecting pipe 13 is changed to be connected to the fifth connecting pipe 17. When the piston rod 6 is pressed next time, the medicine inside the storage box 3 is transported through the fifth connecting pipe 17. When in use, it is possible to achieve "liquid extraction - cleaning liquid injection - liquid extraction - secondary cleaning liquid injection - liquid extraction - medicine transportation" without adjusting the switch, and the operation is simpler.

[0037] Refer to Figure 2 and Figure 4The transparent slide cylinder 4 includes an outer cylinder shell 401, the interior of the outer cylinder shell 401 is fixedly connected with an inclined slider 402, the bottom of the inclined slider 402 is movably connected with a telescopic rod 403, and the piston rod 6 is movably connected with a fixed component 2, and the fixed component 2 includes a side connection block 203, the side connection block 203 is arranged on the outside of the telescopic rod 403 and is movably connected to the telescopic rod 403, and the side of the side connection block 203 is fixedly connected with a spring damping device 204 and a connecting slider 205, and the spring damping device 204 is sleeved on the connecting slider 205, and the spring The other side of the damping device 204 is fixedly connected to the piston rod 6, and the side of the connecting slider 205 is movably connected to the slider 209, the top of the slider 209 is fixedly connected to the fixed plate 206, and the fixed plate 206 is rotatably connected to the movable plate 202, and the other side of the movable plate 202 is rotatably connected to the spring 208, and the side of the spring 208 is fixedly connected to the movable buckle 207, the side of the movable buckle 207 is fixedly connected to the limiting rod 201, the spring 208 is sleeved on the limiting rod 201, and the movable buckle 207 and the fixed block 502 are movably connected.

[0038] In this embodiment, it is necessary to specifically explain that: when in use, the fixed component 2 moves with the piston rod 6. When the piston rod 6 moves upward, the auxiliary transmission mechanism 5 and the piston rod 6 are fixed together by the fixed block 502 and the movable buckle 207. The side connecting block 203 slides upward on the telescopic rod 403. When the piston rod 6 moves to the highest point, the side connecting block 203 moves to the inclined slider 402, so that the side connecting block 203 moves outward. The side connecting block 203 drives the connecting slider 205 to move outward. The connecting slider 205 pushes the slider 209 upward, driving the fixed plate 206 and the bottom of the movable plate 202 to move upward. The top of the movable plate 202 expands outward when moving upward, driving the movable buckle 207 to move outward, and releasing the fixed relationship between the fixed block 502 and the movable buckle 207; when the piston rod 6 moves downward, the side connecting block 203 moves from the inclined slider 402 to the telescopic rod 403. At the retracted rod 403, the side connecting block 203 contracts inwardly, causing the active buckle 207 to move inwardly. When the piston rod 6 moves to the lowest point, the fixed block 502 is clamped by the active buckle 207, so that the active buckle 207 and the fixed block 502 are fixed again, ensuring that when the piston rod 6 is pulled upward, the auxiliary transmission mechanism 5 can follow the movement of the piston rod 6, and before the piston rod 6 moves downward, the auxiliary transmission mechanism 5 can move downward first, thereby driving the waste liquid collection box to rotate and transpose. During the process of exporting and injecting the liquid, the fixed component 2, the auxiliary transmission mechanism 5 and the piston rod 6 can, when exporting, the turntable 509 and the second pulley 512 can rotate first, driving the waste liquid collection box 305 to rotate, and then the waste liquid is exported to the waste liquid collection box 305 through the piston rod 6, which can realize the multi-time collection of the waste liquid, and is convenient for observing the cleaning state of the cleaning liquid and the organizational state at the fixed point of the cleaning liquid guide tube.

[0039] The main difference between this embodiment and the prior art is that in this embodiment, an auxiliary transmission mechanism 5 and a storage box body 3 are used to collect waste liquid under different cleaning times. Specifically: the fourth gear 306 rotates before the piston rod 6 presses down each time, and does not move when it is pulled up, and can collect waste liquid under different cleaning times in different areas on the waste liquid collection box body 305, which is convenient for observing the affected area before guiding medicine, observing the color of the drainage fluid, so as to timely discover abnormal situations such as bleeding and infection, and the operation is more convenient.

[0040] Refer to Figure 1 and Figure 8 , the adjusting assembly 7 includes a movable ring 701. The bottom of the movable ring 701 is movably connected to a fixed block 702. The side of the fixed block 702 is movably connected to a flow-limiting clamping block 703. The bottom of the fixed block 702 is provided with a fixed ring 705. The fixed ring 705 is fixedly connected to the cleaning liquid diversion pipe 8 and the medicine export pipe 9. The cleaning liquid diversion pipe 8 and the medicine export pipe 9 are threadedly connected to the movable ring 701. The top of the fixed ring 705 is fixedly connected to a limiting block 706. A limiting slider 704 is movably connected to the limiting block 706. The flow-limiting clamping block 703 and the limiting slider 704 are fixedly connected.

[0041] In this embodiment, it should be specifically noted that: when in use, 701 can be rotated in the direction of 705, 701 drives 702 to move in the direction of 705, the cooperation of 702 and 703 enables 703 to move in the direction of 8 or 9, and 706 and 705 enable 703 to only move perpendicular to the pipeline direction. By contracting the pipeline through 703, the internal flow rate of the pipeline can be restricted, the flow rate in the pipeline can be controlled, and the pipeline can be timely closed when abnormal waste liquid is observed.

[0042] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
