for example: the sealing portion 40 is in the form of a plug adapted to the shape and size of the first window 101, and the sealing portion 40 closes the first window 101 in the form of plugging and exposes the first window 101 in the form of pulling.

For another example, one side of the sealing portion 40 is hinged to the can body 10, and the sealing portion 40 opens or seals the first window 101 in a rotatable manner with respect to the can body 10.

For another example, the sealing portion 40 is slidably connected to the can body 10, the sealing portion 40 can slide along the surface of the can body 10, and the sealing portion 40 can open or seal the first window 101 in a sliding manner, specifically, if the can body 10 is a square cylindrical can body 10, the sealing portion 40 can be a sliding door disposed on one side wall of the can body 10.

In addition to the above, as shown in fig. 2, the sealing portion 40 can be configured as an annular structure, which is coaxially disposed with the can body 10 and is connected in a rotating manner, and a second window 401 is disposed on the annular structure, and the first window 101 is exposed or sealed by adjusting the overlapping degree of the second window 401 and the first window 101, and the specific scheme is analyzed below and will not be described in detail here.

In the medical specimen sealing apparatus, the first window 101 for access is provided in the side wall of the can body 10, so that the sealing portion 40 is also surrounded by the case 20 after the first window 101 is sealed, and the heat insulating effect of the can body 10 is further improved.

The lifting device 30 is arranged in the casing 20, the lifting device 30 can be positioned between the inner side wall of the casing 20 and the outer side wall of the tank body 10, and can also be positioned between the inner bottom wall of the casing 20 and the bottom of the tank body 10, preferably, the lifting device 30 is a jacking device which is positioned between the inner bottom wall of the casing 20 and the bottom of the tank body 10, so that the space between the inner bottom wall of the casing 20 and the bottom of the tank body 10 can be fully utilized, the gap between the inner side wall of the casing 20 and the outer side wall of the tank body 10 is reduced, and the heat insulation performance of the tank body is improved.

The lifting device 30 can provide a driving force for lifting the tank 10 upwards, and the lifting device 30 can be a hydraulic driving device, so that the tank 10 can be lifted automatically through the hydraulic driving device; the lifting means 30 may also be an elastic means composed of a spring 80, which automatically lifts the can body 10 by its elastic restoring force in a compressed state, and returns the can body to the inside of the housing 20 by its compressive deformation under an external pressing force, which will be described in detail later.

After the can body 10 is exposed from the housing 20, the sealing portion 40 is moved in a corresponding manner according to the fit relationship between the sealing portion 40 and the first window 101, and the first window 101 is exposed, whereby the specimen is taken in and out.

In specific arrangement, as shown in fig. 2 and 3, in the sealing device, the sealing part 40 is of an annular structure, the sealing part 40 is coaxially arranged with the tank 10 and is rotatably connected with the tank, and the sealing part 40 is provided with a second window 401;

the seal 40 is adapted to rotate relative to the can body 10 such that the second window 401 overlaps, partially overlaps or does not overlap the first window 101.

During the rotation of the sealing portion 40 relative to the can body 10 along a predetermined direction (e.g., clockwise or counterclockwise), the relative positional relationship between the second window 401 and the first window 101 changes to misalignment, partial registration, partial registration, and misalignment, and during the actual use, the overlap ratio between the second window 401 and the first window 101 can be specifically adjusted according to the position of the specimen bottle in the can body 10, and the size of the opening can be reduced as much as possible.

In the sealing device, the sealing part 40 is relatively stable in the rotating process and is not easy to cause air flow, thus reducing the convection between the air inside and outside the tank body 10, being beneficial to reducing the outward diffusion of the cold energy inside the tank body 10, improving the heat insulating property of the tank body 10, simultaneously reducing the invasion of bacteria in the external environment into the tank body 10 and reducing the probability of bacterial pollution of the specimen in the tank body 10.

As shown in fig. 3, the tank 10 includes an inner tank 11 and an outer shell 12, the inner tank 11 is used for storing a sample, and a first window 101 is arranged on a side wall of the inner tank 11; annular sealing 40 inlays and establishes on outer casing 12 to can rotate relative outer casing 12, and be equipped with second window 401 on the sealing 40, when second window 401 and first window 101 do not coincide, first window 101 will be blocked by other regions except second window 401 on the sealing 40, in order to guarantee the heat insulating ability of the jar body 10, the inside wall of sealing 40 is provided with heat preservation 402, heat preservation 402 is favorable to reducing the inner tank body 10 and scatters to outside cold volume through first window 101, optionally, heat preservation 402 is the rock wool layer.

In the sealing device, the lifting device 30 is an elastic device, the elastic device 30 is positioned between the tank body 10 and the inner bottom wall of the shell 20, and when the tank body 10 is positioned in the shell 20, the elastic device is in a compressed state;

A telescopic first connecting piece 50 is arranged on the inner side wall of the shell 20, and a second connecting piece 60 matched with the first connecting piece 50 is arranged on the tank body 10;

when the first connecting member 50 is extended, the first connecting member 50 is used to connect with the second connecting member 60 to restrict the can body 10 from being lifted out of the housing 20; when the first connector 50 is retracted, the first connector 50 is adapted to be separated from the second connector 60, allowing the can body 10 to move up and down relative to the housing 20.

Specifically, as shown in fig. 3, the elastic means is one or more sets of springs, when the can body 10 is located inside the housing 20, the elastic means is in a compressed state, the elastic means generates an elastic restoring force due to compression deformation and lifts the can body 10 upwards, at this time, since the first connecting piece 50 arranged on the inner side wall of the housing 20 is connected with the second connecting piece 60 arranged on the can body 10, a restraining force is generated, and the can body 10 is prevented from rising upwards from the housing 20 against the elastic restoring force of the elastic means; if the first connecting member 50 is separated from the second connecting member 60, the restraining effect of the first and second connecting members on the can body 10 is lost, and the can body 10 is lifted upward by the elastic restoring force of the elastic means.

Wherein, the connection of the first connecting member 50 and the second connecting member 60 means that the first connecting member 50 is in contact with and combined with the second connecting member 60, thereby restricting the up-and-down movement of the can body 10.

Compared with a hydraulic transmission device, the lifting device 30 uses the elastic restoring force of the elastic device in the compressed state to lift the tank 10 inside the housing 20 upwards, and has the characteristics of simple structure, small occupied space, light weight and low cost.

In the use process of the sealing device, firstly, the first connecting piece 50 arranged on the inner side wall of the shell 20 is separated from the second connecting piece 60 on the tank body 10, so that the tank body 10 can be lifted upwards under the action of the elastic restoring force of the elastic device and is exposed out of the shell 20; then, the sealing part 40 is moved in a corresponding manner according to the matching relationship between the sealing part 40 and the first window 101, so as to expose the first window 101, thereby performing the access operation of the specimen, for example, the sealing part 40 is a ring structure provided with a second window 401, and is coaxially arranged and rotatably connected with the can body 10, and the second window 401 is overlapped with the first window 101 by rotating the sealing part 40, so as to expose the first window 101; finally, after use, the can body 10 is pressed downwards, when the can body 10 completely falls into the housing 20, the first connecting piece 50 is controlled to extend, so that the first connecting piece 50 is connected with the second connecting piece 60, thereby generating a restraining force, and overcoming the elastic restoring force generated by the elastic device in the downward movement process of the can body 10, and restraining the can body 10 in the housing 20.

In order to ensure that the first connecting member 50 can be smoothly connected with the second connecting member 60 after being extended, the inner bottom wall of the housing 20 is provided with a limiting post 90, and when the tank 10 is pressed against the limiting post 90, the first connecting member 50 is used for being extended outwards.

As shown in fig. 3, the spring 80 provided on the inner bottom wall of the housing 20 is fitted over the stopper 90.

In the descending process of the tank 10, when the bottom of the tank 10 is pressed against the limiting column 90, the limiting column 90 can prevent the tank 10 from continuously descending, at this time, the second connecting piece 60 arranged on the tank 10 corresponds to the height of the first connecting piece 50, therefore, when the tank 10 cannot continuously descend, the first connecting piece 50 is controlled to extend outwards, and the first connecting piece 50 can be connected with the second connecting piece 60 to limit the tank 10 in the shell 20.

When the device is specifically arranged, a groove 201 is formed in the inner side wall of the shell 20, and the first connecting piece 50 is located in the groove 201 and is connected with the inner wall of the groove 201 in a sliding manner;

an electromagnet 70 is arranged at the bottom of the groove 201, and a spring 80 is arranged between the electromagnet 70 and the first connecting piece 50;

when the electromagnet 70 is powered on, a repulsive force is generated between the electromagnet 70 and the first connecting piece 50, so that the first connecting piece 50 extends outwards, and the spring 80 is stretched and deformed;

When the electromagnet 70 is de-energized, the first link 50 is retracted by the elastic restoring force of the spring 80.

Specifically, as shown in fig. 4, the notch of the groove 201 is disposed toward the can body 10, and the first connector 50 slides in the depth direction of the groove 201 to extend or retract with respect to the can body 10.

The first connecting member 50 is made of ferromagnetic material, when the electromagnet 70 is energized, a repulsive force is generated between the electromagnet 70 and the first connecting member 50, so that the first connecting member 50 is driven to move towards the can body 10 until the first connecting member 50 is connected with the second connecting member 60, and in the process that the first connecting member 50 is gradually far away from the electromagnet 70, the spring 80 between the first connecting member 50 and the electromagnet 70 is stretched to generate stretching deformation; when the electromagnet 70 is de-energized, the repulsive force between the electromagnet 70 and the first link 50 disappears, and the first link 50 is retracted toward the side of the housing 20 by the elastic restoring force of the spring 80, thereby being separated from the second link 60.

During the storage period of the specimen, since the can body 10 is confined in the housing 20, the electromagnet 70 needs to be kept in the power-on state, so that the first connecting piece 50 and the second connecting piece 60 can restrain the can body 10 in the connected state, the electromagnet 70 can be electrically connected with an external power module through the circuit design, and can also be electrically connected with a power module in the can body 10, and meanwhile, a switch can be arranged on the surface of the housing 20 to control the on-off of the circuit.

In order to prevent the first connecting member 50 from being separated from the groove 201 during the extending process, a limiting protrusion may be disposed on one of the first connecting member 50 and the groove 201, and a limiting sliding groove engaged with the limiting protrusion may be disposed on the other of the first connecting member 50 and the groove 201, so that when the limiting protrusion reaches the end of the limiting sliding groove during the sliding process of the first connecting member 50, the first connecting member 50 is prevented from continuously sliding, thereby preventing the first connecting member 50 from being separated from the groove 201.

In specific implementation, a U-shaped notch is formed at one end of the first connecting member 50 facing the tank 10, and when the first connecting member 50 is connected to the second connecting member 60, the first connecting member 50 is clamped at the edge of the second connecting member 60 through the U-shaped notch.

In the connection of the first connecting member 50 and the second connecting member 60 shown in fig. 5, the first connecting member 50 is engaged with the edge of the second connecting member 60 by the U-shaped notch, thereby preventing the can body 10 from being lifted upward by the elastic restoring force of the elastic means.

In addition to the above-described coupling form, as shown in fig. 6, the first coupling member 50 is pressed against the upper surface of the second coupling member 60 after being extended, thereby preventing the can body 10 from being lifted upward by the elastic restoring force of the elastic means.

Further, the second connecting members 60 are plate-shaped, and the number of the second connecting members 60 is two, and the two second connecting members are respectively located at the bottom and the top of the tank 10;

For each second connector 60, one or more first connectors 50 are provided on the inner side wall of the housing 20.

Specifically, as shown in fig. 3, the can body 10 is positioned between two second connectors 60 having a plate-shaped structure, and the edges of the second connectors 60 protrude beyond the edges of the can body 10, and when the can body 10 is dropped to a proper position, the first connectors 50 are controlled to protrude to be engaged with the edges of the second connectors 60.

For the second connector 60 disposed at the top of the tank 10, the second connector 60 forms a barrier for isolating the external environment at the top of the tank 10, and meanwhile, the gap between the second connector 60 and the housing 20 is small, thereby being beneficial to improving the overall sealing performance; to the second connecting piece 60 that sets up in the bottom, this second connecting piece 60 has guaranteed that the jar body 10 can steadily descend to in the casing 20 under the exogenic action, avoids jar body 10 atress inhomogeneous the time emergence slope.

For any one second connecting piece 60, one or more first connecting pieces 50 can be arranged on the inner side wall of the shell 20, when the plurality of first connecting pieces 50 are arranged on the inner side wall of the shell 20, the first connecting pieces 50 are located at the same height and are arranged along the circumferential direction, and because the upper and lower two second connecting pieces 60 are respectively clamped with the corresponding one or more first connecting pieces 50, the constraint strength on the tank body 10 is improved, and the stability of the tank body 10 is ensured.

Further, the handle 100 is provided on the upper surface of the second connector 60 positioned on the top of the can body 10.

As shown in fig. 2, the handle 100 is convenient for a user to hold and apply an upward lifting force to the can body 10, so that the can body 10 is quickly lifted out of the housing 20 under the combined action of an external force and an elastic restoring force of the elastic means; meanwhile, the user can move the sealing device by holding the handle 100, which improves portability.

In particular, the handle 100 may be configured to articulate with the second link 60 such that the handle 100 may be laid flat when not in use.

In the sealing device, the housing 20 has a protecting and heat insulating function for the internal can body 10, and since the housing 20 is an open container, in order to further improve the above effect, in a specific embodiment, the sealing device further comprises a cover (not shown) for sealing the opening on the housing 20 after the can body 10 falls into the housing 20.

Thus, the cover is arranged to enable the tank 10 to be accommodated in the sealed cavity formed by the shell 20 and the cover, so as to further enhance the protection and heat preservation effects on the tank 10.

Specifically, the cover is hinged to the housing 20 to form a flip structure, and the opening and sealing of the housing 20 are achieved by flipping the cover, or the cover and the can 10 are two independent parts, and the cover is buckled on the housing 20 to achieve the sealing, and the cover is removed from the housing 20 to achieve the opening of the housing 20.

Further, one of the cover and the housing 20 is provided with a latch, and the other is provided with a fixing portion, and the latch is used for locking or unlocking with the fixing portion.

Meanwhile, a handle may be provided on the cover body so that the user can open the housing 20 by holding the handle.

In another specific embodiment, the sealing device further comprises a cover (not shown), which is fixedly connected to the can body 10;

when the can body 10 falls into the housing 20, the cover is used for pressing the opening of the housing 20 and sealing the opening.

On one hand, the cover body is arranged, so that the tank body 10 can be accommodated in a sealed cavity formed by the shell body 20 and the sealing cover, and the sealing effect of the tank body 10 is further enhanced; on the other hand, when the lid body is pressed against the opening position of the housing 20, the can body 10 stops descending, and has a positioning function.

For example, when the lifting device 30 is an elastic device composed of elasticity, the can body 10 is pressed downward by an external force, so that the can body 10 gradually descends, when the cover body is pressed against the opening position on the housing 20, the can body 10 stops descending, and at this time, the first connecting piece 50 is controlled to extend, so that the first connecting piece 50 is connected with the second connecting piece 60, and restriction is generated, so that the can body 10 is limited in the housing 20.

Further, one of the cover and the housing 20 is provided with a latch, and the other is provided with a fixing portion, and the latch is used for locking or unlocking with the fixing portion. The cover body can be further provided with a handle, so that medical personnel can operate the cover body conveniently, and when the cover body and the shell body 20 are in a locking state, the medical personnel can lift the handle to move the sealing device.

In addition, as shown in fig. 1, in the sealing device, a rubber pad 202 is provided at the bottom of the housing 20.
