In the embodiment of the present invention, three ports 131 are specifically provided, wherein a first port is connected to the first medical device 21 through the first catheter 2; the second port is connected with the bladder and/or the catheter through a second conduit 3; the third port is connected to a second medical device 41 via a third catheter 4. Wherein the first medical device 21 is used for containing a flushing solution such as a medical liquid, a physiological saline solution to be extracted; the second medical device 41 is used for collecting the mixed solution after the rinsing.
As previously mentioned, the temperature of the irrigation solution is too low or too high, which can cause discomfort to the patient, such as bladder spasms. In order to avoid the above problem, the present invention further comprises a heating device 22 at the lower side of the first medical device 21, wherein the heating device 22 is used for heating the flushing solution in the first medical device 21 to a predetermined temperature, and the predetermined temperature is 34-37 ℃, preferably 36-37 ℃. The heating device 22 is only exemplarily shown 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 irrigation solution in the first medical device 21, and a controller (not shown in the figure) receives a signal from the temperature sensor and controls the heating device 22 to heat the irrigation solution to a predetermined temperature.
As previously mentioned, the flushing device of the present invention is capable of selectively placing the ports 131 in communication with the interior of the barrel 13, thereby accomplishing different steps in the flushing process. Preferably, the present invention accomplishes the above operation using the following actuating means. As shown in fig. 2-3, the present invention provides an actuator 11, wherein the actuator 11 includes a selection portion 111 and driving portions 112-115, the selection portion 111 is substantially a circular plate-shaped structure, a selection hole 111-1 is formed therethrough along an axial direction, the selection hole 111-1 is used in cooperation with the ports 131, such that the ports 131 selectively communicate with the inside of the cylinder 13. The driving parts 112-115 are used for driving the selection part 111 to rotate so that the selection hole 111-1 is communicated 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 disposed inside the housing 116, and the coil 115 is disposed between the base 113 and the housing 116. The iron core 114 is disposed on the inner periphery of the base 113, and 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 portion 111. When the coil 115 is energized, the iron core 114 in the driving portion drives the first piston 112 to reciprocate along the axial direction, and further drives the selection portion 111 to rotate.
In order to drive the selection part 111 to rotate, as shown in fig. 3 to 4, a tooth-shaped groove 112-1 is provided on an outer circumferential surface of the first piston 112, and in cooperation therewith, a driving pin 113-1 is provided on an inner surface of the base 113, and the driving pin 113-1 is inserted into the tooth-shaped groove 112-1. For the convenience of explaining the above-mentioned operation, fig. 4 shows a schematic view of the tooth-shaped groove 112-1 of fig. 3 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 along the axial direction, i.e. the first piston 112 reciprocates along the direction of arrow 1 in fig. 4. In the process, for example, the iron core drives the first piston 112 to move in the forward direction first, and at this time, the driving pin 113-1 contacts with the oblique edge of one tooth in the tooth-shaped slot 112-1 first, and according to the force, the first piston 112 will receive a component force along the circumferential direction thereof, and the component force drives the first piston 112 to rotate by an angle, that is, in the direction of arrow 2 in the figure. At this time, the driving pin 113-1 is in contact with the bottom edge 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 contacted with the oblique edge of the opposite tooth after undergoing a section of idle stroke, and because the oblique edges of two adjacent teeth are at the angle shown in fig. 4, the first piston 112 will receive a circumferential component force in the same direction as the previous component force, and further rotate by an angle in the direction of arrow 2 in the figure. The above process is repeated, so as to drive the selection portion 111 to rotate along 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 grooves 112-1 should be offset from the bottom edge of the opposite tooth-shaped groove 112-1 by a distance D, so that the driving pin 113-1 just contacts the crest or the oblique side of the tooth-shaped groove 112-1 each time during the reciprocation of the first piston 112.
Further, to effect the reciprocating motion of the first piston 112. The controller (not shown) is used to control the coil 115 to generate a current in one direction (for example, clockwise), and a magnetic force is applied to the iron core 114, so that the iron core 114 moves in a forward direction and further drives the first piston 112 to move; the controller then controls the coil 115 to generate a current in a direction opposite to the above direction (e.g., counterclockwise), so that the iron core 114 moves in the opposite direction, and further drives the first piston 112 to move. Therefore, when the direction of the current in the coil 115 is continuously controlled to be changed, the first piston 112 can be reciprocated 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 also reciprocate along the axial direction in cooperation with the return force of the return spring.
Preferably, fig. 5 shows an embodiment of the present invention in which the first piston 112 is drivingly connected to the selection portion 111. The first piston 112 is provided with a pin 112-2, and the pin 112-2 is provided with a driving plane; in contrast, a driving hole 111-2 is provided on the selection part 111, and the driving hole 111-2 is provided with a driven plane, thereby achieving efficient power transmission between the first piston 112 and the selection part 111. Fig. 6 shows an embodiment of the present invention in which the first piston 112 is drivingly connected to the plunger 114. A groove 112-3 is formed in the first piston 112, and a protrusion matching with the groove 112-3 is formed on the iron core 114, that is, a revolute pair is formed between the first piston 112 and the iron core 114, so that the first piston 112 and the iron core 114 are rotatably connected in a transmission manner.
Preferably, as shown in fig. 2, a fixing seat 15 is further disposed inside the cylinder 13, the actuating device 11 is sleeved in the fixing seat 15, a plurality of openings 151 corresponding to the plurality of ports 131 are formed in the fixing seat 15, and the selecting portion 111 connects or disconnects the plurality of ports 131 and the plurality of openings 151 in a rotating process.
Preferably, the second piston 12 is disposed inside the cylinder 13, the second piston 12 is connected to a driving interface 122 through a piston rod 121, the driving interface 122 is connected to a driving device 16 (not shown in the drawings), and the controller controls the driving device 16 to operate so as to drive the second piston 12 to reciprocate in the cylinder 13. An end cover 14 is arranged at the other end of the cylinder 13, and the piston rod 121 is movably connected with the end cover 14.
The operation of the flushing device according to the first embodiment of the present invention will now be described as follows:
firstly, the controller controls the heating device 22 to work to heat the flushing solution in the first medical device 21 to a preset temperature; subsequently, the controller controls the actuation device 11 to act, so that the cylinder 13 is communicated with the first medical device 21, and the controller controls the driving device 16 to act to push the second piston 12 to move, so as to draw the flushing solution into the cylinder 13; after sufficient irrigation solution has been drawn, the controller controls the actuation device 11 to actuate the selection part 111 to rotate a predetermined angle in one direction so that the barrel 13 is communicated with the bladder and/or the urinary catheter, and then the controller controls the actuation device 16 to actuate at a first speed so as to push the second piston 12 to move, so that the irrigation solution in the barrel 13 is injected into the bladder and/or the urinary 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 move the second piston 12 more slowly than before, thereby varying the flow rate and/or pressure of the injection to assist the health care provider in controlling the volume of irrigation solution injected into the bladder; after the washing is finished, the controller controls the driving device 16 to act to push the second piston 12 to move, and the mixed solution after the washing is finished is extracted into the cylinder 13; after the extraction is completed, the controller controls the actuating device 11 to act to drive the selection part 111 to rotate continuously for a predetermined angle, so that the cylinder 13 is communicated with the second medical device 41, and then the controller controls the driving device 16 to act to push the second piston 12 to move, so that the mixed liquid in the cylinder 13 is injected into the second medical device. Repeating the steps until the mixed solution is light pink or clear solution, so as to finish the whole bladder irrigation process. Referring preferably to figure 7 of the drawings, a second embodiment of the actuating means of the present invention is shown. Wherein the actuating means comprises a first piston 112 'and a core 113'. The first piston 112 'is rotatably connected to the cylinder 13' and has a selection hole 112'-2 formed therethrough along an axial direction of the first piston 112', and the selection hole 112'-2 is used in cooperation with the ports 131' such that the ports 131 'selectively communicate with the inside of the cylinder 13'. The iron core 113' is disposed at the outer periphery of the first piston 112', a coil 115' is disposed between the iron core 113' and the cylinder 13', and a cover plate 116' is disposed between the actuating device and the cylinder 13' for enclosing the coil 115' and/or the iron core 113 '. The outer circumferential surface of the first piston 112' is provided with a tooth-shaped groove 112' -1, in cooperation therewith, a driving pin 113' -1 is provided on the inner surface of the iron core 113', the driving pin 113' -1 is inserted into the tooth-shaped groove 112' -1, and the coil 115' drives the iron 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 cooperating with the catheter, thereby ensuring that the catheter can be stably and hermetically connected with the ports 131 '.
Here, the operation of the above-described actuator device 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 along the axial direction of the first piston 112', that is, the iron core 113' reciprocates along the direction of arrow 1 in fig. 4. In the process, for example, the iron core 113' first moves in the forward direction, and the driving pin 113' -1 first contacts the oblique edge of one tooth in the tooth-shaped slot 112' -1, and the first piston 112' receives a force component along the circumferential direction thereof according to the force, and the first piston 112' is rotated by an angle, i.e., in the direction of arrow 2 in the figure, under the driving of the force component. At this time, the driving pin 113'-1 is in contact with the bottom edge of the tooth-shaped groove 112' -1. Subsequently, the plunger 113' moves in the opposite direction, and the driving pin 113' -1 is in contact with the oblique side of the opposite tooth after undergoing a certain idle stroke, and because the oblique sides of two adjacent teeth are at the angle as shown in fig. 4, the first piston 112' will receive a component of force in the same direction as before, and further rotate by an angle in the direction of arrow 2 in the figure. The above process is repeated to drive the first piston 112' to rotate in the circumferential direction. As described above, 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 staggered from the bottom edge of the facing tooth-shaped groove 112' -1 by a certain distance D, so that the driving pin 113' -1 just contacts the addendum or the oblique edge of the tooth-shaped groove 112' -1 each time during the reciprocation of the iron core 113 '.
Similarly, in order to achieve the reciprocating motion of the iron 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 iron core 113' to move the iron core 113 'in a forward direction, so as to drive 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 iron core 113' moves in a reverse direction, thereby moving the driving pin 113' -1 in a reverse direction. Therefore, when the direction of the current in the coil 115 'is continuously controlled to be changed, the iron core 113' can be reciprocated in the axial direction. Of course, the present invention is not limited to the above embodiment, and a return spring may be disposed in an axial inner space of the iron core 113', the controller is used to continuously control the on/off of the current in the coil 115', and the iron core 113' may also reciprocate along the axial direction in cooperation with the return force of the return spring.
Compared with the mechanism in the first embodiment, the mechanism in the second embodiment can reduce the axial length, 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.
Figure 8 shows a third embodiment of the flushing device according to the invention. As shown in fig. 8, two ports 131 are disposed at one end of the cylinder 13 at an angle of approximately 180 °, and of course, the angle between the two ports can be set as required, which is not 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 by a second catheter 3; the first medical device 21 is intended to contain a flushing solution, e.g. a medical liquid, physiological saline, to be withdrawn. Likewise, the selective communication of the two ports 131 with the interior of the cylinder 13 is achieved using the actuation means described previously. In the case of the irrigation device shown in fig. 8, the second medical device 41 for collecting the mixed solution after irrigation is eliminated, and instead a urinary catheter (not shown) is provided to communicate with the patient's bladder, which can be switched on and off in a conventional manner (e.g., using a clamp). In use, the urinary catheter is first closed by a clamp or other tool, and the controller controls the heating device 22 to operate to heat the flushing solution in the first medical device 21 to a predetermined temperature; subsequently, the controller controls the actuation device 11 to act, so that the cylinder 13 is communicated with the first medical device 21, and the controller controls the actuation device 16 to act to push the second piston 12 to move, so as to draw the flushing solution into the cylinder 13; after sufficient irrigation solution has been drawn, the controller controls the actuation device 11 to operate to communicate the barrel 13 with the bladder and/or urinary catheter, and then the controller controls the driving device 16 to operate at a first speed to push the second piston 12 to move, so as to inject the irrigation solution in the barrel 13 into the bladder and/or urinary 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 move the second piston 12 more slowly than before, thereby varying the flow rate and/or pressure of the injection to assist the health care provider in controlling the volume of irrigation solution injected into the bladder; after the washing is finished, opening the urine discharge pipe, so that the washed mixed solution naturally flows out of the urine discharge pipe; after the mixed solution in the bladder is flushed, the controller controls the actuating device 11 to operate to communicate the cylinder 13 with the first medical device 21, and then controls the driving device 16 to operate to push the second piston 12 to move, so as to draw the flushing solution into the cylinder 13. The above steps are repeated until the mixed solution is a pale pink or clear solution to complete the whole bladder irrigation process. Due to the fact that the second medical device 41 is omitted, the flushing device can ensure that mixed solution after flushing cannot appear in the barrel 13, the interior of the barrel is clean, and the flushing effect is improved.
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, the ports 131 being alternately connected to the first medical device 21, the bladder and/or the urinary catheter via the first catheter 2 or the second catheter 3. Wherein, the other ends of the second conduits 3-1 and 3-2 connected with the ports are converged to form the conduit 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 flushing is eliminated, instead of providing a urinary catheter (not shown) in the patient's bladder, which can be switched on and off in the usual way (for example by a clamp). The operation of the flushing device is similar to that of the flushing device of fig. 8, and the controller alternately realizes the communication between the port 131 and the first medical device 21, the urinary bladder and/or the urinary catheter, and controls the flushing device to draw the flushing solution from the first medical device 21 and inject the flushing solution into the urinary bladder and/or the urinary catheter, which will not be described in detail herein.
In the fourth embodiment, since four ports 131 are provided, port switching can be completed only by rotating 90 °, shortening the time between port switching; because a plurality of first medical devices 21 are arranged, when one first medical device 21 works, the flushing solution in the other first medical device 21 can be supplemented, so that the flushing device can be continuously used, and the flushing efficiency is improved.
Of course, it should be noted that the number of the ports 131 can be adjusted according to the need, but the number of the ports should be even, and the ports are connected with the first medical device 21, the bladder and/or the urinary catheter alternately through the catheter.
The above embodiments are only used for illustrating the invention and not for limiting the technical solutions described in the 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 embodiments, and therefore, any modification or equivalent replacement of the present invention is made; all such modifications and variations are intended to be included herein within the scope of this disclosure and the appended claims.
