[0029] It is easy to understand that according to the technical scheme of the utility model, a plurality of structure modes and implementation modes that can be replaced each other can be proposed by the general technical personnel in the art without changing the utility model essential spirit. Therefore, the following specific embodiment and drawing are only exemplary description to the technical scheme of the utility model, and should not be regarded as the whole of the utility model or regarded as the limitation or restriction of the technical scheme of the utility model.
[0030] EMBODIMENT
[0031] As Figures 1-4 The utility model discloses a multifunctional medical examination sample subpackaging device of preventing cross contamination, including:
[0032] Shell 1: it is the support structure of whole equipment, provides mounting space and protection for other components.
[0033] Subpackager 2: set up in the side of shell 1, mainly responsible for the distribution according to certain amount and speed with filling liquid, is connected with subpackaging head 4 through pipeline, and filling liquid is transported to subpackaging head 4.
[0034] Multiple storage buckets 3: fixed in the inside of shell 1, are used to store the filling liquid after subpackaging. The middle part of the top end of each storage bucket 3 is fixed with hollow feed column 31, and it is the passageway of filling liquid into storage bucket 3.
[0035] Hollow feed column 31, vertical rod 32 and elastic sealing element 33
[0036] Hollow feed column 31: fixed in the middle part of the top end of each storage bucket 3, and the inside middle part is fixed with vertical rod 32.
[0037] Vertical rod 32: as the component of pushing sealing disc 42, when subpackaging head 4 is inserted into hollow feed column 31, vertical rod 32 extends into the lower cavity of subpackaging head 4 and pushes sealing disc 42 to separate from the lower cavity.
[0038] Elastic seal 33: annular silicone pad, fixed at the top of the vertical rod 32 and in interference fit with the inner wall of the hollow feed column 31. Its outer diameter is 0.5-1.5mm larger than the inner diameter of the hollow feed column 31, which plays a sealing role in the normal state to prevent the leakage of the filling liquid. When the dispensing head 4 is inserted, the elastic seal 33 will be deformed, and a channel will be left between the elastic seal 33 and the lower cavity, forming a flow gap, so that the filling liquid can flow into the storage barrel 3.
[0039] Dispensing head 4, elastic return member 41 and sealing disc 42
[0040] Dispensing head 4: connected to the dispenser 2 through a pipeline, it is the key component for the filling liquid to enter the storage barrel 3. Its interior is provided with a sealing disc 42 supported by an elastic return member 41, which separates the interior of the dispensing head 4 into an upper cavity and a lower cavity with a smaller diameter than the upper cavity.
[0041] Elastic return member 41: a spiral spring, its compression stroke is greater than the displacement required for the sealing disc 42 to move away from the lower cavity. During the insertion and removal of the dispensing head 4 into the hollow feed column 31, the elastic return member 41 provides a restoring force to the sealing disc 42.
[0042] Sealing disc 42: provided with at least two guide protrusions on the circumferential side, and the inner wall of the dispensing head 4 is correspondingly provided with axial guide grooves, the guide protrusions cooperate with the guide grooves to ensure that the sealing disc 42 moves linearly in the dispensing head 4. In the normal state, the sealing disc 42 separates the upper cavity and the lower cavity to prevent the flow of the filling liquid; when the dispensing head 4 is inserted into the hollow feed column 31, the vertical rod 32 pushes the sealing disc 42 away from the lower cavity, so that the filling liquid can flow into the storage barrel 3 through the upper cavity, the lower cavity and the flow gap in sequence.
[0043] The lower cavity of the dispensing head 4 is in a conical structure, and the taper thereof is matched with the shape of the end of the vertical rod 32, so that the vertical rod 32 can smoothly extend into the lower cavity and push the sealing disc 42.
[0044] The edge line of the lower cavity of the dispensing head 4 is provided with a guide chamfer, and the chamfer angle is 15-30 degrees, which plays a guiding role when the dispensing head 4 is inserted into the hollow feed column 31, making the insertion process more smooth.
[0045] Initial state
[0046] In the initial state when the equipment is not working, the elastic seal 33 is tightly attached to the inner wall of the hollow feed column 31, and since the elastic seal 33 is an annular silicone pad with an outer diameter 0.5-1.5mm larger than the inner diameter of the hollow feed column 31, the two form an interference fit, effectively preventing the air in the storage barrel 3 from flowing with the outside world, and preventing possible foreign matter from the outside world from entering the storage barrel 3.
[0047] The sealing disc 42 in the sub-packaging head 4 is tightly in the lower cavity position under the support of the elastic return member 41, separating the sub-packaging head 4 into an upper cavity and a lower cavity. The guide protrusions on the periphery of the sealing disc 42 are matched with the axial guide grooves on the inner wall of the sub-packaging head 4, ensuring the stable position of the sealing disc 42 and preventing the filling liquid from flowing from the upper cavity into the lower cavity.
[0048] Filling starts
[0049] When the filling operation is needed, the operator inserts the sub-packaging head 4 into the hollow feeding column 31. Since the lower cavity edge line of the sub-packaging head 4 is provided with a guide chamfer of 15-30 degrees, the insertion process is smoother.
[0050] As the sub-packaging head 4 extends into the hollow feeding column 31, the vertical rod 32 gradually extends into the lower cavity of the sub-packaging head 4. Because the lower cavity of the sub-packaging head 4 is a conical structure, the taper thereof is matched with the shape of the end of the vertical rod 32, and the vertical rod 32 can accurately push the sealing disc 42. After the sealing disc 42 is pushed by the vertical rod 32, it moves upward against the elastic force of the elastic return member 41. Since the elastic return member 41 is a spiral spring and its compression stroke is greater than the displacement amount required for the sealing disc 42 to move out of the lower cavity, the sealing disc 42 can smoothly move out of the lower cavity.
[0051] At the same time, the elastic sealing member 33 is deformed by the extrusion of the sub-packaging head 4. The originally tightly fitted elastic sealing member 33 and the inner wall of the hollow feeding column 31 form a flow gap.
[0052] At this time, the dispenser 2 starts to work, and the filling liquid is delivered to the upper cavity of the sub-packaging head 4 through the pipeline. After the filling liquid accumulates in the upper cavity, since the sealing disc 42 has moved out of the lower cavity, the filling liquid can flow through the upper cavity, the lower cavity, and then through the flow gap formed by the deformation of the elastic sealing member 33, and finally enters the storage barrel 3.
[0053] Filling ends
[0054] When the filling liquid in the storage barrel 3 reaches the predetermined amount, the operator pulls out the sub-packaging head 4 from the hollow feeding column 31.
[0055] During the pulling-out process, the vertical rod 32 gradually exits the lower cavity of the sub-packaging head 4, and the pushing force acting on the sealing disc 42 disappears. The elastic return member 41 begins to recover its original state, and uses its elastic potential energy to push the sealing disc 42 to move downward along the axial guide groove until the sealing disc 42 returns to the lower cavity, restoring the separation state of the upper and lower cavities of the sub-packaging head 4 and preventing the filling liquid from continuing to flow.
[0056] At the same time, the elastic sealing member 33 loses the extrusion of the dispensing head 4, and restores to the initial shape by relying on the elasticity, is tightly attached to the inner wall of the hollow feeding column 31 again, a seal is formed, the filling liquid in the storage barrel 3 is prevented from leaking, and external air and impurities are also prevented from entering the storage barrel 3. In this way, the whole filling process is completed, the equipment returns to the initial state, and waits for the next filling operation.
[0057] The technical scope of the utility model is not limited to the contents in the above description, and the skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the protection scope of the utility model.
