DETAILED DESCRIPTION
[0015] See also Figure 1-Figure 14 A urological flushing device comprises a flushing device body 1, wherein the flushing device body 1 comprises a liquid injection cylinder 11, a liquid injection cavity 12 is provided in the liquid injection cylinder 11, a flushing liquid injection assembly is installed on the liquid injection cylinder 11, and a heating device 2 is fixedly installed on the flushing device body 1; The heating device 2 includes a heat-insulating shell 21, which is fixedly connected to the outer surface of the liquid injection cylinder 11, and a heating chamber 22 is provided between the inner surface of the heat-insulating shell 21 and the outer surface of the liquid injection cylinder 11. A reflux pipe 221 and a heat supply pipe 222, both of which are connected to the heating chamber 22, are installed on the heat-insulating shell 21, and a heat supply device 3 is installed on the heating device 2; The heating device 3 includes a bracket 31 fixedly connected to the outer surface of the insulation shell 21. A circulation cylinder 33 is fixedly connected to the side surface of the bracket 31 away from the insulation shell 21 through a mounting block 32. A circulating heating component is installed on the circulation cylinder 33.
[0016] When the existing urology flushing device is used, the temperature of the medical cleaning fluid is generally room temperature, which is significantly different from the patient's body temperature. Therefore, if the cleaning fluid is directly injected, it is easy to induce bladder spasm due to cold stimulation, and then hematuria and urinary tract irritation symptoms will be aggravated. Therefore, the medical cleaning fluid to be used needs to be heated before flushing. However, flushing needs to be repeated many times, and a large amount of medical cleaning fluid is needed. Therefore, the preparation time required for preheating is long, and good heat preservation measures are required. Otherwise, it is difficult to stabilize the temperature of the medical cleaning fluid used each time at a certain temperature. In order to solve the above problems, the present invention is provided with a flushing device body 1, a heating device 2 and a heat supply device 3. The heating device 3 is used to continuously deliver the heating medium into the heating device 2 at a constant speed, and the medical cleaning fluid temporarily stored in the flushing device body 1 is heated through heat transfer and heat exchange. Since the heating medium in the heating device 2 flows at a constant speed, it can not only heat the medical cleaning fluid, but also stably heat the medical cleaning fluid to and maintain a certain temperature.
[0017] like Fig.11 , Fig.12 and Fig.13 As shown, the circulating heating component includes a circulating chamber 34 opened in the circulating cylinder 33, two suction pipes 341 are symmetrically installed on the circulating cylinder 33, and a delivery pipe 342 is installed on the circulating cylinder 33. The suction pipe 341 and the delivery pipe 342 are both communicated with the circulating chamber 34, and the delivery pipe 342 is fixedly connected and communicated with the heating pipe 222 through the connecting pipe 343. A first one-way valve is installed in each of the two suction pipes 341, and a second one-way valve is installed in each of the two ends of the delivery pipe 342 close to the circulating cylinder 33. A reciprocating piston 35 is sealingly and slidably connected in the circulating chamber 34, and a sealing adapter sleeve 36 is sealingly and rotatably connected on both outer surfaces of the circulating cylinder 33. A first threaded shaft 37 threadedly connected to the reciprocating piston 35 is fixedly connected between the two sealing adapter sleeves 36, and a second threaded shaft 38 is fixedly connected to the sealing adapter sleeve 36 close to the bracket 31. A driving motor 39 is installed on the bracket 31, and the output end of the driving motor 39 is fixedly connected to the bottom end of the second threaded shaft 38.
[0018] The drive motor 39 is started, and the output end of the drive motor 39 drives the second threaded shaft 38 to rotate. The second threaded shaft 38 drives the first threaded shaft 37 to rotate in the circulation chamber 34 through the sealing adapter sleeve 36. The threaded connection between the first threaded shaft 37 and the reciprocating piston 35 is used to cooperate with the limiting effect of the circulation chamber 34 on the reciprocating piston 35 to drive the reciprocating piston 35 to move in the circulation chamber 34. The drive motor 39 is controlled to perform periodic forward and reverse rotation, which can drive the reciprocating piston 35 to reciprocate up and down in the circulation chamber 34. One end of the two suction pipes 341 is connected to the container for heating and storing the heating medium, and is controlled by the first one-way valve and Due to the one-way conduction restriction of the second one-way valve in the delivery pipe 342, when the reciprocating piston 35 moves upward, the medical cleaning liquid in the circulation chamber 34 above the reciprocating piston 35 is pressed into the delivery pipe 342, and the suction pipe 341 draws new heating medium into the circulation chamber 34 below the reciprocating piston 35. When the reciprocating piston 35 moves downward, the medical cleaning liquid in the circulation chamber 34 below the reciprocating piston 35 is pressed into the delivery pipe 342, and the suction pipe 341 draws new heating medium into the circulation chamber 34 above the reciprocating piston 35. Therefore, with the periodic forward and reverse rotation of the drive motor 39, the heating device 3 can continuously deliver the heating medium into the heating device 2 at a constant speed.
[0019] like Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, a heating liquid partition assembly is installed in the heating chamber 22, and the heating liquid partition assembly includes an extension portion 23 installed on the insulation shell 21, and a mounting tube 24 is installed in the bottom side wall of the extension portion 23, a limiting rod 25 is fixedly connected between an inner surface of the heating chamber 22 and an inner surface of the mounting tube 24, and a partition ring 26 is slidably connected in the heating chamber 22 and the extension portion 23. The partition ring 26 is provided with a guide groove 261 and a limiting groove 262 that are interconnected, and the limiting rod 25 passes through the guide groove 261 and the limiting groove 262. A blocking block 27 matching the limiting groove 262 is slidably connected to the outer surface of the limiting rod 25, and a first return spring 28 is fixedly connected between one side surface of the blocking block 27 and an inner surface of the mounting tube 24, and a magnet is installed in the partition ring 26.
[0020] In order to make more effective use of the thermal energy of the heating medium, the present invention provides a heating liquid partition assembly. When the partition ring 26 overcomes the elastic force of the first return spring 28 on it by means of the magnetic force between the internal magnet and the blocking block 27, the blocking block 27 is blocked in the limiting groove 262. At this time, the partition ring 26 cooperates with the blocking block 27 to form a closed partition ring. The closed partition ring located in the heating chamber 22 can separate the heating medium entering the heating chamber 22 in batches. Each batch of separated heating medium is used to heat the corresponding batch of medical cleaning fluid. The heating medium is continuously fed into the heating chamber 22 by the heat supply device 3. When the partition ring formed by the partition ring 26 and the blocking block 27 is closed, the heating medium that has completed heating the medical cleaning fluid is isolated above the partition ring under the lifting of the heating medium entering the heating chamber 22. As the partition ring moves upward, it is discharged from the heating chamber 22 to prevent the heating medium with lowered temperature from affecting the subsequent heating of the medical cleaning fluid. As the partition ring 26 moves upward, the elastic force of the first return spring 28 on the blocking block 27 increases. When the combined force of the elastic force and gravity on the blocking block 27 is sufficient to overcome the magnetic force of the magnet in the partition ring 26 on the blocking block 27, the blocking block 27 will automatically disengage from the limit groove 262 and quickly move down and reset. Then the partition ring structure opens. Under the action of gravity, the partition ring 26 also moves downward and resets in the vertical direction. After approaching the blocking block 27, the blocking block 27 is again adsorbed and fixed in 272 by the action of magnetism. At this time, the partition ring is closed and then moves upward driven by the newly entered heating medium. This is repeated, and the heating medium that continuously enters the heating chamber 22 can be used to drive the blocking block 27 to move up and down repeatedly in the heating chamber 22 and continue to work.
[0021] like Figure 3 , Figure 4 and Fig.10 As shown, a component for promoting uniform heating is installed in the liquid injection chamber 12, and the component for promoting uniform heating includes a groove 121 opened on an inner surface of the liquid injection chamber 12, a magnetic ring 122 matching the groove 121 is slidably connected in the liquid injection chamber 12, a screen 123 is installed on the magnetic ring 122, and the magnet in the partition ring 26 can attract the magnetic ring 122 by magnetic force.
[0022] With the help of the magnetic attraction of the magnet in the partition ring 26 to the magnetic ring 122, the sealing block 27 will automatically move up and down repeatedly in the heating chamber 22, thereby driving the magnetic ring 122 to move back and forth up and down in the injection chamber 12, stirring the medical cleaning fluid being heated in the injection chamber 12, and promoting convection inside the injection chamber 12, thereby improving the heating effect and making the heating effect more uniform.
[0023] like Figure 3 , Figure 4 and Figure 5 As shown, the flushing liquid injection assembly includes an inlet and outlet pipe 13 fixedly connected to the injection cylinder 11 and communicated with the injection chamber 12, an injection piston 14 is sealingly and slidably connected in the injection chamber 12, the injection piston 14 includes a rubber piston 141, the rubber piston 141 is sealingly and slidably connected in the injection chamber 12, a fixed rod 142 is fixedly connected to the end of the rubber piston 141 away from the injection cylinder 11, a push plate 143 is fixedly connected to the end of the fixed rod 142 away from the rubber piston 141, a three-way pipe fitting 15 is installed on the inlet and outlet pipe 13, a three-way flushing pipe 16 is installed on one end of the three-way pipe fitting 15, and a third one-way valve is installed in the end of the three-way pipe fitting 15 away from the three-way flushing pipe 16.
[0024] The end of the three-way pipe fitting 15 away from the three-way flushing tube 16 is connected to the container for storing medical cleaning fluid. When the injection piston 14 moves downward, the third one-way valve in the connecting end of the three-way pipe fitting 15 and the three-way flushing tube 16 is closed, and the third one-way valve in the end of the three-way pipe fitting 15 away from the three-way flushing tube 16 is opened, so that the medical cleaning fluid is sucked and stored in the injection cavity 12. When the injection piston 14 moves upward, the third one-way valve in the connecting end of the three-way pipe fitting 15 and the three-way flushing tube 16 is opened, and the third one-way valve in the end of the three-way pipe fitting 15 away from the three-way flushing tube 16 is closed, so that the heated medical cleaning fluid in the injection cavity 12 is injected into the patient's bladder through the three-way pipe fitting 15 and the three-way flushing tube 16 to clean it.
[0025] like Fig.14As shown, a transmission device 4 is installed between the injection piston 14 and the second threaded shaft 38, and the transmission device 4 includes a transmission plate 41, on which a threaded sleeve 42 threadedly connected to the second threaded shaft 38 is installed, and an active clamping seat 43 is slidably connected to the end of the transmission plate 41 close to the injection piston 14, and a first clamping groove 44 is provided on the active clamping seat 43, and two limit blocks 45 slidably connected to the first clamping groove 44 are symmetrically fixedly connected to the outer surface of the transmission plate 41 close to the injection piston 14, and the end of the transmission plate 41 away from the injection piston 14 is slidably connected to the bracket 31.
[0026] With the help of the threaded connection between the second threaded shaft 38 and the threaded sleeve 42, and the limiting effect of the bracket 31 on the transmission plate 41, when the output end of the driving motor 39 drives the second threaded shaft 38 to rotate, the second threaded shaft 38 will drive the transmission device 4 to move in the vertical direction. By controlling the forward and reverse rotation of the driving motor 39, the transmission device 4 can be driven to move up and down in the vertical direction. On this basis, by pulling the active clamping seat 43 on the transmission plate 41 to slide toward the push plate 143, the push plate 143 is clamped in the first clamping groove 44 on the active clamping seat 43. Subsequently, the rotation of the second threaded shaft 38 can be used to drive the injection piston 14 to move up and down automatically, thereby completing the injection and suction replenishment of the heated medical cleaning fluid.
[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an injection amount adjusting device 5 is installed in the injection piston 14, and the injection amount adjusting device 5 includes a plurality of empty grooves 51 opened on the rubber piston 141, and a piston rod 52 is sealingly and slidably connected in the empty groove 51, and a baffle 53 is fixedly connected to one end of the piston rod 52 close to the push plate 143, and a second return spring 54 arranged around the piston rod 52 is fixedly connected between the baffle 53 and the rubber piston 141, and a second clamping groove 55 is opened on the fixed rod 142, and a limiting rotating shaft 56 is fixedly connected to the baffle 53, and a holding plate 57 matching the limiting rotating shaft 56 is rotatably connected to the limiting rotating shaft 56.
[0028] Since the present invention uses the second threaded shaft 38 and the transmission assembly to control and drive the injection piston 14 to move back and forth up and down to achieve the suction, replenishment and injection of the medical cleaning liquid after heating, when the drive motor 39 works at a constant speed, the speed of injecting the medical cleaning liquid into the patient's bladder is constant, that is, the injection volume and injection pressure are fixed. In order to be able to adjust the injection pressure according to the use requirements, the present invention is provided with an injection volume adjustment device 5. When the holding plate 57 is clamped in the second clamping groove 55, the injection volume adjustment device 5 will be fixed in the rubber activity The plug 141 will not extend into the injection chamber 12. It is only necessary to rotate the holding plate 57 around the limiting shaft 56 so that it is no longer clamped in the second slot 55. The baffle 53 will drive the piston rod 52 to move upward under the elastic force of the second return spring 54 and extend into the injection chamber 12, thereby reducing the volume of the injection chamber 12. Since the speed and stroke of the injection piston 14 are fixed each time it moves up and down, the volume of the injection chamber 12 can be affected and changed with the help of the injection volume adjustment device 5, thereby affecting the injection pressure and injection speed of the medical cleaning fluid.
[0029] In the present invention, the drive motor 39 is started, and the output end of the drive motor 39 drives the second threaded shaft 38 to rotate. The second threaded shaft 38 drives the first threaded shaft 37 to rotate in the circulation chamber 34 through the sealing adapter sleeve 36. The threaded connection between the first threaded shaft 37 and the reciprocating piston 35 is used to cooperate with the limiting effect of the circulation chamber 34 on the reciprocating piston 35 to drive the reciprocating piston 35 to move in the circulation chamber 34. The drive motor 39 is controlled to perform periodic forward and reverse rotation to drive the reciprocating piston 35 to reciprocate up and down in the circulation chamber 34. One end of the two suction pipes 341 is connected to the container for heating and storing the heating medium, and is controlled by the first one-way valve in the suction pipe 341. and the one-way conduction restriction of the second one-way valve in the delivery pipe 342, when the reciprocating piston 35 moves up, the medical cleaning liquid in the circulation chamber 34 above the reciprocating piston 35 is pressed into the delivery pipe 342, and the suction pipe 341 sucks the new heating medium into the circulation chamber 34 below the reciprocating piston 35; when the reciprocating piston 35 moves down, the medical cleaning liquid in the circulation chamber 34 below the reciprocating piston 35 is pressed into the delivery pipe 342, and the suction pipe 341 sucks the new heating medium into the circulation chamber 34 above the reciprocating piston 35. Therefore, with the periodic forward and reverse rotation of the driving motor 39, the heating device 3 can continuously and constantly deliver the heating medium into the heating chamber 22 at a constant speed; When the partition ring 26 uses the magnetic force between its internal magnet and the blocking block 27 to make the blocking block 27 overcome the elastic force of the first return spring 28 and thus be blocked in the limiting groove 262, the partition ring 26 cooperates with the blocking block 27 to form a closed partition ring, and the heating device 3 continuously delivers the heating medium into the heating chamber 22. When the partition ring formed by the partition ring 26 and the blocking block 27 is closed, the heating medium that has completed heating the medical cleaning fluid is isolated above the partition ring under the lifting of the heating medium entering the heating chamber 22, and is discharged from the heating chamber 22 as the partition ring moves upward, so as to prevent the heating medium after the temperature is reduced from affecting the subsequent heating of the medical cleaning fluid. When the blocking block 27 is moved, the elastic force of the first return spring 28 on the blocking block 27 increases. When the combined force of the elastic force and gravity on the blocking block 27 is sufficient to overcome the magnetic force of the magnet in the partition ring 26 on the blocking block 27, the blocking block 27 will automatically disengage from the limit groove 262 and quickly move down and reset. Then the partition ring structure opens. Under the action of gravity, the partition ring 26 also moves down and resets in the vertical direction. After approaching the blocking block 27, the blocking block 27 is again adsorbed and fixed in 272 by the magnetic force. At this time, the partition ring is closed and then moves upward driven by the newly entered heating medium. This is repeated, and the heating medium that continuously enters the heating chamber 22 can be used to drive the blocking block 27 to repeatedly move up and down in the heating chamber 22 and continue to work. With the help of the magnetic attraction of the magnet in the partition ring 26 to the magnetic ring 122, the blocking block 27 will automatically move up and down repeatedly in the heating chamber 22, thereby driving the magnetic ring 122 to move up and down in the injection chamber 12, stirring the medical cleaning liquid being heated in the injection chamber 12, and promoting the convection inside the injection chamber 12, thereby improving the heating effect and making the heating effect more uniform; When the holding plate 57 is engaged in the second slot 55, the injection volume adjusting device 5 will be fixed in the rubber piston 141 and will not extend into the injection chamber 12. The holding plate 57 only needs to be rotated around the limiting shaft 56 so that it is no longer engaged in the second slot 55. Then, the baffle 53 will drive the piston rod 52 to move upward under the elastic force of the second return spring 54 and extend into the injection chamber 12, thereby reducing the volume of the injection chamber 12. Since the speed and stroke of the injection piston 14 are fixed each time it moves up and down, the injection volume adjusting device 5 can be used to affect and change the volume of the injection chamber 12, thereby affecting the injection pressure and injection speed of the medical cleaning fluid.
