DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example: Figure 1 , Figure 2 and Figure 5-Figure 7 As shown, an automated microorganism staining device includes a housing 100 , a carrier 110 , a liquid dripping mechanism 120 , a liquid mixing mechanism 130 and a flushing mechanism 140 .

[0030] The front of the box 100 is open, and a drainage pipe 102 is provided at the back of the box 100; the object carrier 110 is slidably connected to the box 100, and the object carrier 110 is used to place multiple glass slides (blood smears or bone marrow smears); the dripping mechanism 120 is installed on the box 100, and the dripping mechanism 120 is used to drip Wright's stain and Wright's buffer on the glass slide located on the object carrier 110; the mixing mechanism 130 is installed on the box 100, and the mixing mechanism 130 is used to evenly mix the Wright's buffer and the Wright's stain on the glass slide; the flushing mechanism 140 is installed on the box 100, and the flushing mechanism 140 is used to flush the glass slide.

[0031] Specifically, a plurality of glass slides are placed on the object carrier 110, and then, Wright's stain is first dripped on the glass slide by the dripping mechanism 120, and after standing for 0.5-1 minute, Wright's buffer is quantitatively dripped on the glass slide, and then, the Wright's buffer and the Wright's stain are mixed by the mixing mechanism 130. After the mixing is completed, the plurality of glass slides are left to stand for a period of time (8-15 minutes);

[0032] After the specified time is reached, the box 100 is tilted backwards, and the washing mechanism 140 is connected to an external water source, and then the glass slide is washed by the washing mechanism 140. After the washing is completed, the glass slide is left to stand for a period of time, and the staining work is completed after the water on the glass slide is drained.

[0033] like Figure 6 As shown, the object carrier 110 includes a support plate 111 , a plurality of placement slots 112 , a plurality of groups of object taking slots 113 , two electric push rods 114 and a plurality of liquid drain slots 115 .

[0034] The support plate 111 is slidably connected to the slide groove 101 opened on the inner wall of the box body 100; multiple placement grooves 112 are opened on the top surface of the support plate 111, and the placement grooves 112 are used to place glass slides; multiple groups of retrieval grooves 113 are opened on the top surface of the support plate 111, and the multiple groups of retrieval grooves 113 are respectively connected to the multiple placement grooves 112; two electric push rods 114 are installed on the inner wall of the box body 100, and the extended ends of the two electric push rods 114 are fixedly connected to the support plate 111; multiple drainage grooves 115 are opened on the top surface of the support plate 111, and the drainage grooves 115 are connected to the retrieval grooves 113 and the placement grooves 112.

[0035] Specifically, when it is necessary to place a glass slide on the pallet 111, the two electric push rods 114 are started to push the pallet 111 toward the outside of the box 100, so that part of the pallet 111 is outside the box 100, and then multiple glass slides are placed in multiple placement slots 112 respectively, and then the electric push rods 114 are used to drive the pallet 111 to move into the box 100.

[0036] By providing the taking groove 113 , it is convenient to take out the glass slide in the placing groove 112 by hand; by providing the drainage groove 115 , it is convenient to drain the water on the supporting plate 111 .

[0037] like Figure 5-Figure 7 As shown, the dripping mechanism 120 includes a mounting frame 121 , a dual-axis motor 122 , a lead screw 123 , a lead screw nut 124 , a mounting seat 125 and two sets of dripping components 126 .

[0038] The mounting frame 121 is mounted on the outer side of the box body 100; the dual-axis motor 122 is mounted on the mounting frame 121, and the dual-axis motor 122 includes a first power output shaft and a second power output shaft; the lead screw 123 is rotatably connected to the box body 100, and one end of the lead screw 123 is fixedly connected to the first power output shaft of the dual-axis motor 122; the lead screw nut 124 is sleeved on the lead screw 123; the mounting seat 125 is fixedly sleeved on the lead screw nut 124, and the mounting seat 125 is slidably connected to the inner wall of the box body 100; two sets of dripping assemblies 126 are respectively used to drip Wright's stain and Wright's buffer onto the glass slide.

[0039] Specifically, by starting the dual-axis motor 122, the first power output shaft of the dual-axis motor 122 will drive the lead screw 123 to rotate, thereby causing the lead screw nut 124 to move along the lead screw 123, thereby driving the mounting seat 125 to slide along the inner wall of the box 100, thereby driving the two sets of dripping assemblies 126 to move. When the dripping assemblies 126 are located directly above the glass slide, Wright's stain is dripped onto the glass slide through one of the dripping assemblies 126. After a period of time, Wright's buffer is dripped onto the glass slide through the other dripping assembly 126.

[0040] like Figure 6 As shown, the drip assembly 126 includes a liquid storage barrel 1261, a liquid dropper 1262, a micro pump 1263 and a connecting hose 1264. The liquid storage barrel 1261 is installed through the top surface of the box 100, and the liquid storage barrel 1261 is used to contain Wright's dye or Wright's buffer; the liquid dropper 1262 is installed on the bottom surface of the mounting seat 125; the micro pump 1263 is installed on the top surface of the mounting seat 125, and the infusion end of the micro pump 1263 is connected to the liquid dropper 1262; one end of the connecting hose 1264 is connected to the liquid extraction end of the micro pump 1263, and the other end of the connecting hose 1264 is connected to the liquid storage barrel 1261.

[0041] Specifically, by starting the micro pump 1263, the Wright's stain or Wright's buffer in the liquid storage barrel 1261 is transported to the dropper 1262 through the connecting hose 1264, and the Wright's stain or Wright's buffer is dripped onto the glass slide by the dropper 1262.

[0042] like Figure 3-Figure 7 As shown, the liquid mixing mechanism 130 includes an air guide cover 131 , a connecting pipe 132 , a hose 133 , a transverse pipe 134 , a plurality of air nozzles 135 , an arc plate 136 , an extrusion plate 137 , a plurality of slide bars 138 and a plurality of springs 139 .

[0043] The air guide cover 131 is installed on the mounting frame 121, and the second power output shaft of the dual-axis motor 122 extends into the air guide cover 131 and is rotatably connected to the air guide cover 131; the connecting pipe 132 is fixedly connected to the air guide cover 131; the hose 133 is fixedly connected to the connecting pipe 132; the cross pipe 134 is installed in the box body 100, and one end of the cross pipe 134 is connected to the hose 133; multiple air nozzles 135 are all installed on the cross pipe 134, and the multiple air nozzles 135 are respectively located directly above the multiple placement grooves 112. The arc plate 136 is fixedly connected to the side of the box body 100, and the arc plate 136 contacts the hose 133; the side of the extrusion plate 137 close to the arc plate 136 is provided with an arc protrusion; multiple sliding rods 138 are fixedly connected to the extrusion plate 137, and multiple sliding rods 138 are slidably connected to the arc plate 136; multiple springs 139 are fixedly connected to the arc plate 136 and the extrusion plate 137.

[0044] The dripping mechanism 120 further includes a cam 128 and a fan blade 129. The cam 128 is fixedly sleeved on the power output shaft of the dual-axis motor 122, and the cam 128 is used to intermittently push the extrusion plate 137 to move; the fan blade 129 is located in the wind guide cover 131 and is installed on the second power output shaft of the dual-axis motor 122.

[0045] Specifically, when the dual-axis motor 122 is running, its second power output shaft will drive the fan blades 129 to rotate, and the rotating fan blades 129 will suck the outside air into the air guide cover 131, and then transport the air to the cross tube 134 through the connecting pipe 132 and the hose 133, and the air in the cross tube 134 will be blown to multiple glass slides through multiple air nozzles 135, and the air blown out by the air nozzles 135 will mix the Wright buffer and the Wright stain on the glass slides.

[0046] When the dual-axis motor 122 is running, its first power output shaft will drive the cam 128 to rotate, and the rotating cam 128 will intermittently push the extrusion plate 137 to move. When the cam 128 pushes the extrusion plate 137 to move, the extrusion plate 137 will cooperate with the arc plate 136 to squeeze the hose 133. When the hose 133 is squeezed, the air in the connecting pipe 132 cannot be transported to the cross pipe 134 through the hose 133, and the air nozzle 135 no longer blows out air.

[0047] The rotating cam 128 cooperates with multiple springs 139 to intermittently squeeze the hose 133, so that the air in the air guide cover 131 intermittently enters the cross tube 134, causing the multiple air nozzles 135 to intermittently blow out air. The air nozzles 135 intermittently blow air toward the Wright's buffer and the Wright's stain on the glass slide. During each blowing, the Wright's buffer and the Wright's stain can form a new mixing interface, thereby improving the mixing efficiency.

[0048] like Figure 5As shown, the flushing mechanism 140 includes a main water pipe 141 and a plurality of diversion pipes 142. The main water pipe 141 is installed on the top surface of the box body 100; the plurality of diversion pipes 142 are fixedly connected to the main water pipe 141, and the plurality of diversion pipes 142 are respectively located directly above the plurality of placement slots 112.

[0049] Specifically, when the glass slide needs to be rinsed, the main water pipe 141 is connected to an external water source and water is transported into the main water pipe 141. The water in the main water pipe 141 will flow to multiple branch pipes 142, and the water in the branch pipes 142 will flow to the glass slide, thereby rinsing the glass slide.

[0050] like Figure 2 As shown, an automated microorganism staining device further includes a support bar 103, two support blocks 104 and an adjustment mechanism 150. The support bar 103 is mounted on the bottom surface of the box 100; the two support blocks 104 are both mounted on the bottom surface of the box 100. The adjustment mechanism 150 includes a hydraulic cylinder 151 and a push plate 152. The hydraulic cylinder 151 is mounted on the bottom surface of the box 100; the push plate 152 is mounted on the extended end of the hydraulic cylinder 151.

[0051] Specifically, by starting the hydraulic cylinder 151, the extended end of the hydraulic cylinder 151 will push the push plate 152 to move, thereby lifting the front side of the box 100 upward and tilting the box 100 backward; when the glass slides in the box 100 are rinsed, it is beneficial for the water on the support plate 111 and the glass slides to flow downward.

[0052] Working principle: During specific use, the two electric push rods 114 are started to push the support plate 111 toward the outside of the box 100, so that part of the support plate 111 is outside the box 100, and then multiple glass slides are placed in multiple placement grooves 112 respectively, and then the electric push rods 114 are used to drive the support plate 111 to move into the box 100, so that the multiple glass slides are directly below the dropper 1262.

[0053] Then, by starting the micro pump 1263, the Wright's stain in the liquid storage barrel 1261 is transported to one of the dropper tubes 1262 through the connecting hose 1264, and the Wright's stain is dropped onto the glass slide through the dropper tube 1262;

[0054] After 0.5-1 minute, another micro pump 1263 is started to transfer the Wright's buffer in another liquid storage barrel 1261 to another dropper 1262, and the Wright's buffer is dropped on the glass slide through the dropper 1262. At this time, the Wright's dye and the Wright's buffer on the glass slide will merge together.

[0055] Restart the dual-axis motor 122, and the first power output shaft of the dual-axis motor 122 will drive the lead screw 123 to rotate, thereby causing the lead screw nut 124 to move along the lead screw 123, thereby driving the mounting seat 125 to slide along the inner wall of the box 100, thereby driving the two sets of droplet assemblies 126 to move. When the two sets of droplet assemblies 126 are located directly above another glass slide, repeat the above operation to drop Wright's stain and Wright's buffer onto the glass slide below.

[0056] Repeat the above steps until all slides are dripped with Wright's stain and Wright's buffer, and the Wright's stain and Wright's buffer on the slides are fused together.

[0057] Then, the two electric push rods 114 are started to drive the support plate 111 to move, thereby driving the multiple glass slides to move. When the Wright stain and Wright buffer on the glass slides are directly below the air nozzle 135, the two electric push rods 114 are closed.

[0058] Then, by starting the dual-axis motor 122, the second power output shaft of the dual-axis motor 122 will drive the fan blades 129 to rotate, and the rotating fan blades 129 will suck the outside air into the air guide cover 131, and then transport the air to the cross pipe 134 through the connecting pipe 132 and the hose 133, and the air in the cross pipe 134 will be blown to the multiple glass slides through the multiple air nozzles 135, and the air blown out by the air nozzles 135 will mix the Wright buffer and the Wright stain on the glass slides.

[0059] When the dual-axis motor 122 is running, its first power output shaft will drive the cam 128 to rotate. The rotating cam 128 and the multiple springs 139 will cooperate to squeeze the hose 133 intermittently, and then the air in the air guide cover 131 will intermittently enter the cross pipe 134, causing the multiple air nozzles 135 to blow out air intermittently.

[0060] Air is blown toward the Wright buffer and the Wright stain on the glass slide through the air nozzle 135. Each time air is blown, a new mixing interface can be formed, thereby improving the mixing efficiency.

[0061] After the mixing is completed, the dual-axis motor 122 is turned off and the glass slide is laid flat and left to stand for a period of time.

[0062] When the designated time is reached, the hydraulic cylinder 151 is activated, and the extended end of the hydraulic cylinder 151 pushes the push plate 152 to move, thereby lifting the front side of the box body 100 upward, so that the box body 100 tilts backward.

[0063] Then, by connecting the main water pipe 141 to an external water source and conveying water into the main water pipe 141 , the water in the main water pipe 141 will flow to the multiple branch pipes 142 , and the water in the branch pipes 142 will flow to the glass slides, thereby rinsing the glass slides.

[0064] After rinsing, let it stand for a while until the water on the slide is drained and the staining is completed.
