Technical Field

[0001] The utility model relates to the technical field of liquid suction devices, in particular to a liquid suction adapter recovery box and a pushable gun head integrated device. Background Art

[0002] A common operation in clinical and routine laboratories. There are different brands of automatic aspirators on the market that allow liquids in solutions to be quickly and conveniently aspirated. During the experiment, different specifications of the adapter for the aspirator are required for different experimental requirements. The experimental process requires aspirating the solution in the cell dish (bottle). Usually, a 5mL or 1000μL gun tip is used to connect directly to the aspirator hose. Because it involves one gun tip, it is more convenient to take; but when aspirating solutions in containers such as 12-well plates, 24-well plates, and 96-well plates, the experiment selects a pipette that is compatible with the container to ensure the cleanliness of the experimental environment and the efficiency of the inspection work.

[0003] In the prior art, when laboratory staff use a pipette adapter to aspirate the solution in the well plate, they will put multiple gun tips on the bottom of the pipette adapter to extract the liquid. After the liquid is extracted, the staff needs to manually unplug the gun tips one by one, which is rather cumbersome. Secondly, during the experiment, there is no fixed place for the pipette adapter, and it is usually placed directly on the desktop of the laboratory table, which can easily cause secondary contamination of the experimental environment.

[0004] Therefore, a liquid suction adapter recovery box and a pushable gun head integrated device are proposed to solve the above problems. Utility Model Content

[0007] As a preferred embodiment, a ring magnet 1 is fixedly embedded inside the through hole 1.

[0008] As a preferred embodiment, the pushable gun head assembly includes two annular magnets, both sides of the surface of the two annular magnets are wrapped with iron wires, both sides of the bottom of the two iron wires are penetrated and connected with two connecting rods, the bottom of the two annular magnets is connected with a spring, the surfaces of the bottom sides of the two iron wires are wrapped around the two sides of the top of the spring, the spring is located on the inner side of the four connecting rods, the other ends of the four connecting rods are fixedly connected to a gun head push plate, a plurality of through holes are opened on the surface of the gun head push plate, and a plurality of the gun heads are located below the gun head push plate.

[0009] As a preferred embodiment, a plurality of pipette heads are connected to the bottom of the pipette adapter, a plurality of the gun heads are sleeved on the surfaces of the plurality of pipette heads, and the bottom of the spring is attached to the surface of the pipette adapter.

[0010] As a preferred embodiment, the top of the second ring magnet is adsorbed on the bottom of the first ring magnet by magnetic force.

[0011] As a preferred embodiment, the surfaces of the plurality of pipette tips are movably embedded in the interiors of the plurality of through holes 2.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] The utility model firstly passes the automatic liquid suction hose through the through hole one from the outside of the box body, connects the top of the liquid suction adapter and the automatic liquid suction hose, then increases the distance between the bottom of the spring and the top of the gun head pushing plate by compressing the spring, extends the liquid suction adapter into the interior of the pushable gun head assembly from between the connecting rods on the two sides, and makes the surfaces of multiple liquid suction heads embedded in the interiors of multiple through holes two, completes the fixation of the liquid suction adapter, and installs the gun heads on the surfaces of the other ends of the multiple liquid suction heads, puts the installed pushable gun head assembly and the liquid suction adapter into the inner cavity of the box body, makes the annular magnet two and the annular magnet one fixed by magnetic attraction, starts the automatic liquid suction device, places the orifice plate containing liquid in the inner cavity of the box body by holding it by hand, makes one end of multiple gun heads extend into multiple test tubes respectively, and starts the automatic liquid suction device. Under the action of the pipette, the waste liquid in the test tube is sucked out and discharged into the waste liquid bottle. When the gun tip needs to be replaced, the gun tip collection box is placed under the gun tip in the inner cavity of the box, and then the hand is extended into the interior of the box and pinches one side of the pipette adapter to lift it upward to deform the spring that fits the pipette adapter. In the process of the pipette adapter moving upward, since the diameter of the top of the gun tip is larger than the opening diameter of the through hole 2, it will be blocked and pushed by the gun tip push plate, so that the gun tip is separated from the surface of the pipette head and falls into the gun tip recovery box. This design of the pushable gun tip assembly can disassemble multiple gun tips at one time, which enhances practicality. At the same time, during the experiment, the pipette adapter can be fixed to the inner cavity of the box by a magnet, and there is no need to place the pipette adapter on the desktop of the laboratory bench, thus avoiding secondary pollution of the laboratory environment.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides a technical solution: a liquid suction adapter recovery box pushable gun head integrated device, comprising: a box body 1, a through hole 101 is opened on the top of the box body 1, a pushable gun head assembly 2 is arranged in the inner cavity of the box body 1, a liquid suction adapter 3 is arranged inside the pushable gun head assembly 2, and a plurality of gun heads 4 are connected to the bottom of the liquid suction adapter 3.

[0023] Specifically: when the gun tip needs to be replaced, place the gun tip collection box below the gun tip 4 in the inner cavity of the box body 1, and then pull the automatic pipette hose, and the pipette adapter 3 connected to the automatic pipette hose will move upward, so that the spring 205 that fits with the pipette adapter 3 is deformed. In the process of the pipette adapter 3 moving upward, since the diameter of the top of the gun tip 4 is larger than the opening diameter of the through hole 204, it will be blocked and pushed by the gun tip push plate 203, so that the gun tip 4 is separated from the surface of the pipette head 301 and falls into the gun tip recovery box. This design allows the pushable gun tip assembly 2 to disassemble multiple gun tips at one time, which enhances practicality. At the same time, during the experiment, the pipette adapter can be fixed to the inner cavity of the box body 1 by a magnet, and there is no need to place the pipette adapter on the desktop of the laboratory bench, thereby avoiding secondary pollution of the laboratory environment.

[0024] In one embodiment, a ring magnet 102 is fixedly embedded inside the through hole 101 .

[0025] Specifically: it is used to fix the ring-shaped magnet 102 to prevent the ring-shaped magnet 102 from deviating and affecting the normal use of the device.

[0026] In one embodiment, the pushable gun tip assembly 2 includes an annular magnet 201, both sides of the surface of the annular magnet 201 are wrapped with iron wires 206, both sides of the bottom of the two iron wires 206 are penetrated and connected with two connecting rods 202, the bottom of the annular magnet 201 is connected with a spring 205, the bottom surfaces of the two iron wires 206 are wrapped around both sides of the top of the spring 205, the spring 205 is located on the inner side of the four connecting rods 202, the other ends of the four connecting rods 202 are fixedly connected with a gun tip push plate 203, a plurality of through holes 204 are opened on the surface of the gun tip push plate 203, and a plurality of gun tips 4 are located below the gun tip push plate 203.

[0027] Specifically: when the gun tip needs to be replaced, place the gun tip collection box below the gun tip 4 in the inner cavity of the box body 1, and then pull the automatic liquid suction hose, and the liquid suction adapter 3 connected to the automatic liquid suction hose will move upward, so that the spring 205 that fits with the liquid suction adapter 3 is deformed. In the process of the liquid suction adapter 3 moving upward, the diameter of the top of the gun tip 4 is larger than the opening diameter of the through hole 204, so it will be pushed off and fall into the gun tip recovery box. This design allows the pushable gun tip assembly 2 to disassemble multiple gun tips at one time, and its practicality is enhanced. When the liquid suction adapter 3 needs to be replaced, all the gun tips 4 are now removed, and then the automatic liquid suction hose is pulled to increase the distance between the bottom of the spring 205 and the top of the gun tip push plate 203, and multiple liquid suction heads 301 are pulled out from the inside of the through hole 204, so that the liquid suction adapter 3 can be taken out from between the connecting rods 202 on the two sides, and finally the top of the liquid suction adapter 3 is separated from the automatic liquid suction hose.

[0028] In one embodiment, a plurality of pipette heads 301 are connected to the bottom of the pipette adapter 3 , a plurality of gun tips 4 are sleeved on the surfaces of the plurality of pipette heads 301 , and the bottom of the spring 205 is attached to the surface of the pipette adapter 3 .

[0029] Specifically: after the pushable gun tip assembly 2 assists in disassembling the gun tip 4 , the liquid pipetting adapter 3 will return to the initial position under the elastic force of the spring 205 so that a new gun tip 4 can be installed.

[0030] In one embodiment, the top of the second ring magnet 201 is attracted to the bottom of the first ring magnet 102 by magnetic force.

[0031] Specifically: since the pushable gun head assembly 2 is adsorbed on the bottom of the ring-shaped magnet 102 through the ring-shaped magnet 201, the convenient pushable gun head assembly 2 can be disassembled.

[0032] In one embodiment, the surfaces of the plurality of pipette tips 301 are movably embedded inside the plurality of second through holes 204 .

[0033] Specifically: pull the automatic pipette hose, and the pipette adapter 3 connected to the automatic pipette hose will move upward, causing the spring 205 that fits the pipette adapter 3 to deform. In the process of the pipette adapter 3 moving upward, the diameter of the top of the gun tip 4 is larger than the opening diameter of the through hole 204, so it will be knocked off and fall into the gun tip recovery box.

[0034] Working principle: first, pass the automatic pipette hose through the through hole 101 from the outside of the box body 1 and connect the top of the pipette adapter 3 and the automatic pipette hose, then increase the distance between the bottom of the spring 205 and the top of the gun head push plate 203 by compressing the spring, extend the pipette adapter 3 into the interior of the pushable gun head assembly 2 from between the connecting rods 202 on the two sides and embed the surfaces of multiple pipette heads 301 in the interior of multiple through holes 204, complete the fixation of the pipette adapter 3, and install the gun head 4 on the surface of the other end of the multiple pipette heads 301, put the installed pushable gun head assembly 2 and the pipette adapter 3 into the inner cavity of the box body 1, so that the annular magnet 201 and the annular magnet 102 are fixed by magnetic attraction, start the automatic pipette, and place the orifice plate containing liquid in the inner cavity of the box body 1 by holding it in the hand, so that one end of the multiple gun heads 4 extends into multiple In the test tube, the waste liquid in the test tube is sucked out under the action of the automatic pipette and discharged into the waste liquid bottle. When the gun tip needs to be replaced, the gun tip collection box is placed under the gun tip 4 in the inner cavity of the box body 1, and then the hand is extended into the interior of the box body 1 and one side of the pipette adapter 3 is pinched and lifted upward to deform the spring 205 that fits the pipette adapter 3. In the process of the upward movement of the pipette adapter 3, since the diameter of the top of the gun tip 4 is larger than the opening diameter of the through hole 204, it will be blocked and pushed by the gun tip push plate 203, so that the gun tip 4 is separated from the surface of the pipette head 301 and falls into the gun tip recovery box. The design of the pushable gun tip assembly 2 can disassemble multiple gun tips at one time, which enhances practicality. At the same time, during the experiment, the pipette adapter can be fixed to the inner cavity of the box body 1 by a magnet, and there is no need to place the pipette adapter on the desktop of the laboratory bench, thereby avoiding secondary pollution of the laboratory environment.
