[0035] The frame 1 and the cleaning table 2 are provided with a clamping assembly 4 for fixing the two ports of the irrigation device 3. The clamping assembly 4 is arranged in multiple groups and distributed in a linear array. The piston rod of the first telescopic cylinder 11 is connected with an upper guide assembly 5, which is used to guide the water flow to impact the inner wall of the irrigation device 3.

The frame 1 is also provided with a water supply assembly 8, which provides water to the upper guide assembly 5 and the lower guide assembly 6 respectively.

[0036] Reference Figure 1 , Figure 4 and Figure 5 The upper flow guide assembly 5 includes an upper flow guide rod 51, an upper flow guide cap 52 and an upper water pipe 53. The upper flow guide rod 51 is set in a cylindrical shape, one end of the upper flow guide rod 51 is fixedly mounted on the piston rod of the first telescopic cylinder 11, and the other end of the upper flow guide rod 51 is fixedly mounted with an upper flow guide cap 52, and the upper flow guide cap 52 is distributed in a trumpet shape from top to bottom with an opening facing downward, and an upper water pipe 53 is fixedly mounted on the frame 1, and a water inlet is opened on the upper water pipe 53, and the upper water pipe 53 and the upper flow guide rod 51 are set as coaxial axes, and the outer diameters of the upper flow guide rod 51 and the upper flow guide cap 52 are both smaller than the inner diameter of the bottle mouth of the irrigation device 3.

[0037] When in use, the water flow inside the upper water pipe 53 is ejected by the water pump and flows into the interior of the injector 3 along the outer side walls of the upper guide rod 51 and the upper guide cap 52. The upper guide cap 52 guides the water flow to diffuse around. The impact force of the water flow impacts the inner wall of the injector 3. The piston rod on the first telescopic cylinder 11 drives the upper guide rod 51 and the upper guide cap 52 to move vertically up and down, thereby changing the impact position of the water flow on the interior of the injector 3.

[0038] Reference Figure 4 , Figure 5 and Figure 6The lower flow guide assembly 6 includes a lower flow guide rod 61, a lower flow guide cap 62, a pressing block 65 and a lower water pipe 66. The lower flow guide rod 61 is also set to be cylindrical, one end of the lower flow guide rod 61 is fixedly mounted on the piston rod of the second telescopic cylinder 12, the other end of the lower flow guide rod 61 is fixedly mounted with a lower flow guide cap 62, a lower water pipe 66 is fixedly mounted on the frame 1, and a water inlet is also provided on the lower water pipe 66, the lower water pipe 66 and the lower flow guide rod 61 are set to be coaxial, and the outer diameters of the lower flow guide rod 61 and the lower flow guide cap 62 are both smaller than the inner diameter of the bottle mouth of the injector 3.

[0039] The lower guide cap 62 opens upward in a trumpet shape from bottom to top, and a circular array of arc grooves are provided on the lower guide cap 62.

[0040] A first guide groove 63 is arranged on the top of the lower guide cap 62. The inner wall of the first guide groove 63 is in an arc shape. The first guide groove 63 extends from bottom to top and from inside to outside. The water flow impacted by the upper guide cap 52 is made to impact upward through the first guide groove 63. A second guide groove 64 is arranged on the top of the arc groove opened on the lower guide cap 62. The second guide groove 64 extends from top to bottom and from inside to outside. The water flow impacted by the lower guide cap 62 is made to impact downward when passing through the second guide groove 64.

[0041] When in use, the water flow inside the lower water pipe 66 is ejected by the water pump and flows into the interior of the irrigator 3 along the outer side walls of the lower guide rod 61 and the lower guide cap 62. The lower guide cap 62 guides the water flow to diffuse in all directions and impact the inner wall of the irrigator 3. When the upper guide cap 52 contacts the lower guide cap 62, the water flow impacted from the upper guide cap 52 impacts the inner wall of the first guide groove 63, so that the water flow impacts upward and washes the inner wall of the upper port of the irrigator 3. When the upper guide cap 52 presses the pressing block 65 downward, the water flow on the lower guide rod 61 passes through the gap between the pressing block 65 and the lower guide rod 61, and the water flow impacts the inner wall of the second guide groove 64, changing the impact direction of the water flow, so that the water flow impacts downward and washes the inner wall of the lower port of the irrigator 3.

[0042] Reference Figure 4 , Figure 6 and Fig. 9The clamping assembly 4 includes a base 41, a clamping cylinder, a clamping block and a reset spring 43. The base 41 is fixedly mounted on the frame 1, and is used to fix one end of the perfusion device 3; a clamping cylinder is fixedly mounted on the upper water pipe 53, and the inner wall of the clamping cylinder and the upper water pipe 53 are in a connected state. A clamping block is provided on the clamping cylinder, and the clamping blocks are arranged in multiple and annular arrays. The clamping interface 42 surrounded by the clamping blocks is used to fix the other end of the perfusion device 3. A reset spring 43 located inside the clamping cylinder is installed on the clamping block, and the reset spring 43 is used to allow the clamping block to have space to move up and down.

[0043] When in use, one end of the perfusate 3 is aligned with the base 41 and placed on the base 41, and one end of the perfusate 3 is fixed. By compressing the return spring 43, the card interface 42 on the card block is aligned with the other end of the perfusate 3, and the bottle body of the perfusate 3 is fixed.

[0044] Reference Figure 5 , Figure 6 , Figure 7 and Figure 8 The pumping assembly 7 includes a first pumping hole 71, a connecting tube, a second pumping hole 73 and a pumping pump 74. The first pumping holes 71 are provided in plurality and are respectively provided on the pressure block of the rebound pressure block. A connecting tube is provided on the top of the rebound pressure block. The connecting tube is provided in a cylindrical shape. The first pumping holes 71 are all connected to the connecting hole. The upper guide rod 51 and the upper guide cap 52 are provided with a second pumping hole 73 in communication. When the wastewater in the irrigation device 3 is pumped out, one of the outlets of the second pumping hole 73 is located inside the upper water pipe 53. The pumping pump 74 is provided on the upper water pipe 53.

[0045] When in use, the first telescopic cylinder 11 drives the upper guide cap 52 to move downward, and the second telescopic cylinder 12 drives the lower guide cap 62 to move upward. The upper guide cap 52 is pressed on the pressing block 65. At this time, the first pumping hole 71, the connecting hole 72 and the second pumping hole 73 are in a connected state. When the waste water inside the irrigation device 3 has no time to be discharged from the perforation of the base 41 and exceeds the lower guide cap 62, the upper water pipe 53 stops supplying water and the water pump 74 is started. The water pump 74 draws the waste water inside the irrigation device 3 back to the upper water pipe 53 through the first pumping hole 71, the connecting hole 72 and the second pumping hole 73 and discharges it.

[0046] Reference Figure 3 The water supply assembly 8 includes a main water supply pipe 81, a branch water supply pipe 82 and a valve 83. The frame 1 is provided with a main water supply pipe 81 and a plurality of valves 83, and a plurality of branch water supply pipes 82 are provided on the main water supply pipe 81. A single branch water supply pipe 82 is connected to a water inlet on a single upper water pipe 53 through a hose, and a single branch water supply pipe 82 is connected to a water inlet on a single lower water pipe 66 through a hose, and the water supply of each branch water supply pipe 82 is controlled by a single valve 83.

[0047] When in use, the corresponding valve 83 is opened according to actual needs, and the water flows through the main water supply pipe 81, the branch water supply pipe 82 and the hose in sequence, and finally reaches the upper water pipe 53 or the lower water pipe 66 to flush a certain number of irrigation devices 3.

[0048] The implementation principle of a multifunctional blood perfusion flushing machine in the embodiment of the present application is:

[0049] When in use, the perfusion device 3 is first placed on the base 41, the base 41 fixes one end of the bottle mouth of the perfusion device 3, and the other end of the perfusion device 3 is fixed through the card interface 42 on the card connection block, thereby completing the fixation of the bottle body of the perfusion device 3.

[0050] Then, the first telescopic cylinder 11 is started to drive the upper guide rod 51 and the upper guide cap 52 to move up and down reciprocatingly, and water is introduced into the upper water pipe 53 through the main water supply pipe 81, the branch water supply pipe 82 and the hose. The water flows downward along the upper guide rod 51 and the upper guide cap 52 under the drive of the water pump. When the water flows through the upper guide cap 52, the water flows to the surroundings and the water flows on the inner wall of the irrigator 3; at the same time, the second telescopic cylinder 12 is started to drive the lower guide rod 61 and the lower guide cap 62 to move up and down. The lower water pipe 66 moves back and forth, and water flows into the lower water pipe 66. Driven by the water pump, the water flows upward along the lower guide rod 61 and the lower guide cap 62. When the water flows through the lower guide cap 62, the water flows to the surroundings and flows on the inner wall of the irrigator 3. The upper guide rod 51, the upper guide cap 52, the lower guide rod 61 and the lower guide cap 62 guide the impact water flow to complete the flushing of the middle part of the inner wall of the irrigator 3. The water flows directly out through the gap between the base 41 and the irrigator 3.

[0051] Afterwards, the water supply assembly 8 stops supplying water to the lower guide assembly 6 and only supplies water to the upper guide assembly 5, so that the upper guide cap 52 contacts the lower guide cap 62, and the water flow impacting the upper guide cap 52 contacts the first guide groove 63, changing the impact direction of the water flow, and the water flow impacts upward along the first guide groove 63. At this time, the first telescopic cylinder 11 drives the upper guide rod 51 to move upward, and the second telescopic cylinder 12 drives the lower guide rod 61 to move upward synchronously, so that the water flow repeatedly washes the dead corner of the inner wall below the upper port of the irrigator 3;

[0052] Afterwards, the water supply component 8 stops supplying water to the upper guide component 5 and only supplies water to the lower guide component 6, so that the upper guide cap 52 moves downward, and pressure is applied to the pressing block 65. The pressing block 65 moves downward to form a gap between the lower guide rod 61. At this time, the water flow impacting the lower guide rod 61 passes through the gap and the second guide groove 64 in sequence. The second guide groove 64 changes the impact direction of the water flow, and the water flow impacts downward. At this time, the first telescopic cylinder 11 drives the upper guide rod 51 to move downward, and the second telescopic cylinder 12 drives the lower guide rod 61 to move downward synchronously, so that the water flow repeatedly washes the dead corner of the inner wall above the lower port of the injector 3.

[0053] After the water flow has finished flushing the dead corners of the inner wall of the middle part and the inner wall below the upper port of the injector 3, when flushing the dead corner of the inner wall above the lower port of the injector 3, the upper guide cap 52 is pressed on the pressing block 65 of the lower guide cap 62, and the upper guide cap 52 and the lower guide cap 62 are both located at the lower part of the injector 3, and the waste water inside the injector 3 flows out from the base 41. If the waste water inside the injector 3 is higher than the first pumping hole 71, the pumping pump 74 is started, and the water flow is directly pumped back from the second pumping hole 73, the connecting hole 72 and the first pumping hole 71 to the upper water pipe 53, and the hose connector is disconnected to discharge the waste water inside the injector 3. After the waste water is completely discharged, the water supply component 8 is started to supply water to the lower guide component 6 to ensure the flushing quality of the dead corner of the inner wall above the lower port of the injector 3 by the impact water flow.

[0054] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0055] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
