In an embodiment of the invention, the number of ports 131 is specifically three, wherein a first port is connected to the first medical device 21 via the first catheter 2; the second port is connected with the bladder and/or the catheter through a second catheter 3; the third port is connected to the second medical device 41 by a third catheter 4. Wherein the first medical device 21 is used for containing a flushing solution such as a liquid medicine and physiological saline to be extracted; the second medical device 41 is used for collecting the mixed solution after rinsing.
As mentioned above, too low or too high a temperature of the irrigation solution can cause discomfort to the patient, such as the possibility of bladder cramping. In order to avoid the above problems, the present invention is further provided with a heating device 22 at the lower side of the first medical device 21, the heating device 22 being used for heating the flushing solution in the first medical device 21 to a predetermined temperature, the predetermined temperature being 34-37 ℃, preferably 36-37 ℃. The heating device 22 is shown only by way of example in fig. 1, and in order to control the heating temperature, the heating device 22 is further provided with a temperature sensor (not shown in the figure) for detecting the temperature of the flushing solution in the first medical device 21, and a controller (not shown in the figure) receives a signal of the temperature sensor and controls the heating device 22 to heat the flushing solution to a predetermined temperature.
As previously described, the flushing device of the present invention can selectively put the ports 131 in communication with the inside of the cylinder 13, thereby completing the various steps in the flushing process. Preferably, the present invention employs the following actuation means to accomplish this. As shown in fig. 2-3, the present invention provides an actuating device 11, the actuating device 11 is provided with a selecting portion 111 and driving portions 112-115, the selecting portion 111 is of a substantially circular plate-like structure, through selecting holes 111-1 are formed in the selecting portion 111 along the axial direction, and the selecting holes 111-1 are used in cooperation with the plurality of ports 131, so that the plurality of ports 131 are selectively communicated with the inside of the cylinder 13. The driving parts 112 to 115 are used to drive the selection part 111 to rotate so that the selection hole 111-1 communicates with one of the ports 131. Preferably, the driving part includes a first piston 112, a core 114, a coil 115, a base 113, and a housing 116. Wherein, the base 113 is fixedly arranged inside the housing 116, and the coil 115 is arranged between the base 113 and the housing 116. The iron core 114 is disposed on the inner periphery of the base 113, one end of the first piston 112 is in transmission connection with the iron core 114, and the other end is in transmission connection with the selection part 111. When the coil 115 is energized, the iron core 114 in the driving part drives the first piston 112 to reciprocate along the axial direction, and further drives the selecting part 111 to rotate.
In order to drive the selection part 111 to rotate, as shown in fig. 3-4, a toothed groove 112-1 is provided at the outer circumferential surface of the first piston 112, and in cooperation therewith, a driving pin 113-1 is provided at the inner surface of the base 113, the driving pin 113-1 being inserted into the toothed groove 112-1. For convenience of explanation of the above operation, a schematic view of the tooth-shaped groove 112-1 of fig. 3 is shown in fig. 4 after being expanded in the circumferential direction. Referring to fig. 3-4, the driving pin 113-1 is fixed, and the iron core drives the first piston 112 to reciprocate in the axial direction, that is, the first piston 112 reciprocates in the direction of arrow 1 in fig. 4. In this process, for example, the iron core drives the first piston 112 to move first in the forward direction, at this time, the driving pin 113-1 first contacts the bevel edge of one tooth in the tooth-shaped groove 112-1, and as the force is applied, the first piston 112 will be subjected to a component force along its circumferential direction, and the first piston 112 is driven by the component force to rotate by an angle, that is, rotate in the direction of arrow 2 in the figure. At this time, the driving pin 113-1 contacts the bottom side of the tooth-shaped groove 112-1. Subsequently, the iron core drives the first piston 112 to move in the opposite direction, and the driving pin 113-1 is in contact with the inclined edge of the opposite tooth after undergoing a dead stroke, and since the inclined edges of the adjacent teeth are at an angle as shown in fig. 4, the first piston 112 is subjected to a circumferential component force in the same direction as the above, and is further rotated by an angle in the direction of arrow 2 in the figure. The above process is repeated, thereby driving the selection part 111 to rotate in the circumferential direction. In order to smoothly perform the above-mentioned rotation process, as shown in fig. 4, the top of one tooth of the tooth-shaped groove 112-1 should be offset from the bottom edge of the opposite tooth-shaped groove 112-1 by a distance D, thereby allowing the driving pin 113-1 to be just contacted with the tooth tip or the inclined edge of the tooth-shaped groove 112-1 each time during the reciprocating motion of the first piston 112.
Further, in order to achieve the reciprocating movement of the first piston 112. Controlling the coil 115 with the controller (not shown) to generate a current in one direction (e.g., clockwise), wherein a magnetic force is applied to the iron core 114, so that the iron core 114 moves in a forward direction and further moves the first piston 112; the controller then controls the coil 115 to generate a current in a direction opposite to that described above (e.g., counter-clockwise) such that the core 114 moves in a reverse direction and further moves the first piston 112. Thus, when the current direction change in the coil 115 is continuously controlled, the first piston 112 can be made to reciprocate in the axial direction. Of course, the present invention is not limited to the above embodiment, and a return spring may be disposed in the axial inner space of the first piston 112, and the controller may continuously control the on/off of the current in the coil 115, and the first piston 112 may reciprocate in the axial direction in cooperation with the return force of the return spring.

Fig. 6 shows an embodiment of the present invention in which the first piston 112 is drivingly connected to the core 114. Wherein, a groove 112-3 is provided in the first piston 112, and a protrusion matched with the groove 112-3 is provided on the iron core 114, that is, a revolute pair is formed between the first piston 112 and the iron core 114, thereby realizing rotatable transmission connection between the first piston 112 and the iron core 114.

The outer circumferential surface of the first piston 112' is provided with a toothed groove 112' -1, in cooperation therewith, a driving pin 113' -1 is provided at the inner surface of the core 113', the driving pin 113' -1 is inserted into the toothed groove 112' -1, and the coil 115' drives the core 113' to reciprocate in the axial direction of the first piston 112 '. And, the ports 131' are further provided with interfaces 131' -1 for use with the catheter, thereby ensuring that the catheter can be stably and sealingly connected with the ports 131 '.
Here, the operation of the actuator will be described. Referring to fig. 4, in order to drive the first piston 112' to rotate, the coil 115' drives the iron core 113' to reciprocate in the axial direction of the first piston 112', i.e., the iron core 113' reciprocates in the direction of arrow 1 in fig. 4. In this process, for example, the core 113' is first moved in the forward direction, and at this time, the driving pin 113' -1 first contacts the oblique side of one tooth in the tooth groove 112' -1, and as a result of the force applied, the first piston 112' is subjected to a force component in the circumferential direction thereof, and the first piston 112' is rotated by the force component, i.e., rotated in the direction of arrow 2 in the drawing. At this time, the driving pin 113'-1 contacts the bottom side of the tooth groove 112' -1. Subsequently, the core 113' moves in the reverse direction, and the driving pin 113' -1 is in contact with the oblique side of the opposite tooth after undergoing a blank stroke, and the first piston 112' is subjected to a circumferential component force in the same direction as described above and is further rotated by an angle in the direction of arrow 2 in the drawing, since the oblique sides of the adjacent teeth are angled as shown in fig. 4. The above process is repeated, thereby driving the first piston 112' to rotate in the circumferential direction. As described above, in order to smoothly perform the above-described rotation process, as shown in fig. 4, the top of one tooth of the tooth-shaped groove 112' -1 should be offset from the bottom edge of the opposite tooth-shaped groove 112' -1 by a distance D, thereby allowing the driving pin 113' -1 to be just contacted with the tooth tip or the inclined edge of the tooth-shaped groove 112' -1 at a time during the reciprocation of the core 113'.
Similarly, to achieve the reciprocation of the core 113'. Controlling the coil 115 'to generate a current in one direction (e.g., clockwise) by the controller (not shown), wherein a magnetic force is applied to the core 113' such that the core 113 'moves in a forward direction, thereby driving the driving pin 113' -1 to move in an axial direction; subsequently, the controller controls the coil 115' to generate a current in a direction opposite to the above direction (e.g., counterclockwise) so that the core 113' moves in a reverse direction, thereby driving the driving pin 113' -1 to move in a reverse direction. Accordingly, when the current direction change in the coil 115 'is continuously controlled, the reciprocation of the core 113' in the axial direction can be achieved. Of course, the present invention is not limited to the above embodiment, and a return spring may be provided in the axial inner space of the iron core 113', and the controller may continuously control the on/off of the current in the coil 115', and the iron core 113' may reciprocate in the axial direction in cooperation with the return force of the return spring.
The mechanism in the second embodiment can reduce the axial length compared with the mechanism in the first embodiment, so that the structure is more compact, the occupied space of the device can be effectively saved, and the whole device is convenient to realize miniaturization.
Fig. 8 shows a third embodiment of the flushing device according to the invention. As shown in fig. 8, two ports 131 are provided at one end of the cylinder 13 at an angle of approximately 180 °, and of course, the angle between the two ports may be set as required, which will not be described herein. Wherein the first port 131 is connected to the first medical device 21 through the first catheter 2; the second port 131 is connected to the bladder and/or urinary catheter via a second catheter 3; the first medical device 21 is used for holding an irrigation solution, such as a medical solution, and physiological saline, waiting to be extracted. Likewise, the selective communication of the two ports 131 with the interior of the cylinder 13 is achieved using actuation means as previously described. For the irrigation device shown in fig. 8, the second medical device 41 for collecting the mixed solution after irrigation is omitted, and instead a urinary catheter (not shown) is provided in communication with the patient's bladder, which may be controlled on and off in a conventional manner (e.g., using a clip). When in use, the catheter is closed by a clamp or other tool, and the controller controls the heating device 22 to work so as to heat the flushing solution in the first medical device 21 to a preset temperature; subsequently, the controller controls the actuation means 11 to act so that the cartridge 13 communicates with the first medical device 21, the controller controls the driving means 16 to act to push the second piston 12 to move, drawing the flushing solution into the cartridge 13; after sufficient irrigation solution has been withdrawn, the controller controls the actuation means 11 to move to bring the cartridge 13 into communication with the bladder and/or catheter, and then the controller controls the drive means 16 to move at a first speed to push the second piston 12 to move, injecting the irrigation solution within the cartridge 13 into the bladder and/or catheter; during the above process, when a predetermined amount of irrigation solution is injected, the controller controls the drive device 16 to act at a second speed to push the second piston 12 to move more slowly than before, thereby changing the flow rate and/or pressure of the injection to assist the healthcare worker in controlling the volume of irrigation solution injected into the bladder; after the flushing is finished, opening the urination tube to enable the flushed mixed solution to naturally flow out of the urination tube; after the mixed solution after the flushing in the bladder has been completed, the controller controls the actuation means 11 to act so that the cartridge 13 communicates with the first medical device 21, and then the controller controls the driving means 16 to act to push the second piston 12 to move, drawing the flushing solution into the cartridge 13. The above steps are repeated until the mixed solution is a light pink or clear solution to complete the entire bladder irrigation process. Due to the elimination of the second medical device 41, the flushing device can ensure that the mixed solution after flushing can not appear in the cylinder 13, ensure the cleaning of the cylinder and improve the flushing effect.
Fig. 9 shows a fourth embodiment of the flushing device according to the invention. Unlike the embodiment shown in fig. 8, four ports 131 are evenly provided at one end of the barrel 13, which ports 131 are alternately connected to the first medical device 21, the bladder and/or the urinary catheter by means of the first catheter 2 or the second catheter 3. Wherein the other ends of the second catheters 3-1 and 3-2 connected with the ports are converged to form a catheter 3-3 and then communicated with the bladder and/or the catheter. As in fig. 8, the second medical device 41 for collecting the mixed solution after rinsing is omitted, instead of a urination tube (not shown) in the patient's bladder, which may be controlled in a conventional manner (e.g. by a clip). The operation is similar to the irrigation device of fig. 8, and the controller alternately enables communication between the port 131 and the first medical device 21, the bladder and/or the catheter, and controls the irrigation device to withdraw irrigation solution from the first medical device 21 and to inject irrigation solution into the bladder and/or the catheter, which will not be described in detail herein.
In the fourth embodiment, since four ports 131 are provided, the port switching can be completed only by rotating by 90 °, and the time between the port switching is shortened; because the plurality of first medical devices 21 are arranged, when one of the first medical devices 21 works, the flushing solution in the other first medical device 21 can be supplemented, so that the flushing device can be used continuously, and the flushing efficiency is improved.
Of course, it should be noted that the number of ports 131 may be adjusted as desired, but the number of ports should be even and such that the ports are alternately connected to the first medical device 21, the bladder and/or the urinary catheter via the catheter.
The above embodiments are only for illustrating the present invention and not for limiting the technical solutions described in the present invention, and although the present invention has been described in detail in the present specification with reference to the above embodiments, the present invention is not limited to the above specific embodiments, and thus any modifications or equivalent substitutions are made to the present invention; all technical solutions and modifications thereof that do not depart from the spirit and scope of the invention are intended to be included in the scope of the appended claims.
