The embodiment of the application provides a sample analyzer. The following are detailed descriptions.

Fig. 1 is a schematic structural diagram of an embodiment of a sample analyzer according to an embodiment of the present disclosure. As shown in fig. 1, the sample analyzer 100 includes a rack 110 and a door assembly 120, the door assembly 120 being mounted to the rack 110, the door assembly 120 moving relative to the rack 110 to open or close (as shown in fig. 2) an interior space of the rack 110.

As shown in fig. 3, a rack 110 of the sample analyzer 100 is provided with a sample dispensing module 111, a reagent dispensing module 112, a washing module 113, a reagent storage module 114, a detection module (not shown), and a reaction module 115, wherein the reagent storage module 114 is used for storing a reagent. The reaction assembly 115 includes a reaction site for placing a reaction cup and an incubation assembly for incubating a reaction solution in the reaction cup, the reaction solution being obtained from a sample and a reagent. The sample dispensing assembly 111 is used for dispensing a sample into a reaction cup. The reagent dispensing assembly 112 is used to dispense reagents from the reagent storage assembly 114 into reaction cups. The detecting component (not shown in the figure) is used for detecting the reaction solution to obtain a detection result, so as to realize the analysis of the sample by the sample analyzer 100.

A cleaning assembly 113 may be further provided on the frame 110, and the cleaning assembly 113 is used for cleaning the reaction cup. After the sample analyzer 100 completes the analysis of the reaction solution in the reaction cup, the reaction cup may be cleaned by the cleaning assembly 113.

As shown in fig. 3, a sample supply track 116 may also be provided on the rack 110, the sample supply track 116 being used to transport sample cups in which samples are placed. Each of the reagent dispensing module 112 and the sample dispensing module 111 includes a moving member and a pipetting needle provided on the moving member. The pipetting needle of the reagent dispensing assembly 112 is used to aspirate reagent from the reagent storage assembly 114 and release the reagent into the reaction cuvette of the reaction assembly 115. The pipetting needle of the sample dispensing assembly 111 is used for aspirating a sample from a sample cup on the sample supply track 116 and releasing the sample into a reaction cup of the reaction assembly 115, so that a reagent is mixed with the sample in the reaction cup to obtain a reaction solution. Then, the reaction solution in the reaction cup is incubated by the incubation component of the reaction component 115, so that the detection component can detect the reaction solution in the reaction cup and obtain an accurate detection result.

The structures of the rack 110, the reaction module 115, the sample dispensing module 111, the reagent dispensing module 112, and the detection module may be conventional structures, and will not be described in detail here.

As shown in fig. 1 and 3, the sample analyzer 100 further includes a water tank 117 mounted to the rack 110, a syringe assembly 118, a vacuum pump assembly (not shown), and a pressure detection assembly (not shown), wherein the water tank 117 is respectively communicated with the sample dispensing assembly 111 and the reagent dispensing assembly 112 through a pipeline. The syringe assembly 118 is disposed on the tubing between the water tank 117 and the sample and reagent dispensing assemblies 111 and 112 to provide power to the sample and reagent dispensing assemblies 111 and 112 to aspirate or discharge fluids.

After the pipetting needle of the sample pipetting module 111 or the reagent pipetting module 112 is moved to the position for aspirating a sample or a reagent, the syringe module 118 may be controlled to supply a negative pressure to the pipetting needle of the sample pipetting module 111 or the reagent pipetting module 112, so that the pipetting needle of the sample pipetting module 111 or the reagent pipetting module 112 aspirates a sample or a reagent into the pipetting needle.

After the pipetting needle of the sample pipetting module 111 or the reagent pipetting module 112 is moved to the position for releasing the sample or the reagent, the syringe module 118 may be controlled to apply positive pressure to the pipetting needle of the sample pipetting module 111 or the reagent pipetting module 112, so that the pipetting needle of the sample pipetting module 111 or the reagent pipetting module 112 releases the sample or the reagent, thereby completing the pipetting of the sample or the reagent.

The pressure detection assembly is used for detecting the pressure in the pipeline. Specifically, the pressure detection module is disposed on the pipeline between the pipetting needle of the sample pipetting module 111 or the reagent pipetting module 112 and the water tank 117 to detect a pressure value of the pipeline between the pipetting needle of the sample pipetting module 111 or the reagent pipetting module 112 and the water tank 117, so as to accurately control the amount of liquid supplied to the pipetting needle of the sample pipetting module 111 or the reagent pipetting module 112 according to the pressure value.

The vacuum pump assembly is communicated with the cleaning assembly 113 to provide the cleaning assembly 113 with a power for sucking liquid, so that the cleaning assembly 113 sucks the liquid in the reaction cup out.

In some embodiments, door panel assembly 120 may be separable from chassis 110 in a first direction (e.g., from bottom to top in fig. 1). Therefore, the door panel assembly 120 can be detached from the frame 110 by controlling the door panel assembly 120 to move in the first direction relative to the frame 110.

As shown in fig. 4 and 5, the sample analyzer 100 includes a hinge structure 127, the hinge structure 127 includes a connection part 1270 and a connection shaft 1272, one of the connection part 1270 and the connection shaft 1272 is connected to the door panel assembly 120, the other of the connection part 1270 and the connection shaft 1272 is connected to the rack 110, the connection part 1270 is provided with a connection hole (not shown), and the connection shaft 1272 is inserted into the connection hole along a direction opposite to the first direction (a direction from top to bottom in fig. 4 and 5) to mount the door panel assembly 120 to the rack 110. That is, when the door panel assembly 120 is mounted to the chassis 110 in the first direction (the direction from the bottom to the top) with respect to the chassis 110, the connecting shaft 1272 is moved in the first direction with respect to the connecting member 1270 until the connecting shaft 1272 can be withdrawn from the connecting hole, thereby separating the door panel assembly 120 from the chassis 110 in the first direction.

It should be noted that the connecting member 1270 may be connected to the rack 110, and the connecting shaft 1272 may be connected to the door panel assembly 120, or the connecting member 1270 may be connected to the door panel assembly 120, and the connecting shaft 1272 may be connected to the rack 110, and the door panel assembly 120 may be mounted on the rack 110 only by inserting the connecting shaft 1272 into the connecting hole in the reverse direction of the first direction, and the door panel assembly 120 may be separated from the rack 110 when moving in the first direction with respect to the rack 110.

Specifically, the door panel assembly 120 includes a reinforcing plate 121, and a decorative plate 126 provided on the reinforcing plate 121. A supporter 122 is provided on the reinforcing plate 121, and a connecting shaft 1272 is mounted on the supporter 122 so that the connecting shaft 1272 is connected to the door panel assembly 120. Attachment member 1270 is mounted on frame 110. The connection shaft 1272 is inserted into the connection hole in the reverse direction of the first direction and is rotatable within the connection hole to rotatably connect the door panel assembly 120 with the chassis 110. In the opposite direction of the first direction, the supporting member 122 abuts against the connecting member 1270 to limit the movement of the door panel assembly 120 in the opposite direction of the first direction relative to the chassis 110.

In another embodiment, the connecting shaft 1272 may be mounted on the connecting member 1270, and the connecting hole may be opened in the supporting member 122 such that the connecting shaft 1272 is inserted into the connecting hole in the reverse direction of the first direction. In the reverse direction of the first direction, the connecting member 1270 abuts against the supporting member 122 to limit the movement of the door panel assembly 120 in the reverse direction of the first direction with respect to the chassis 110.

Of course, the door panel assembly 120 and the rack 110 may be connected without the connecting shaft 1272 being engaged with the connecting hole, and the door panel assembly 120 may be mounted on the rack 110 in the reverse direction of the first direction in other ways, and the door panel assembly 120 may be separated from the rack 110 in the first direction.

As shown in fig. 4-7, the sample analyzer 100 further includes a limiting structure 128, the limiting structure 128 can limit the door plate assembly 120 to prevent the door plate assembly 120 from moving in the first direction relative to the rack 110 and separating from the rack 110, and the limiting structure 128 can also release the limiting of the door plate assembly 120 to allow the door plate assembly 120 to move in the first direction relative to the rack 110 and separating from the rack 110.

The limiting structure 128 comprises a limiting component 1280 and an abutting component 1283, one of the limiting component 1280 and the abutting component 1283 is connected with the door panel assembly 120, and the other of the limiting component 1280 and the abutting component 1283 is connected with the frame 110. The position-limiting member 1280 is movable between an abutting position (shown in fig. 5 and 6) and an avoiding position (shown in fig. 4 and 7), and the position-limiting member 1280 is configured to abut against the abutting member 1283 when in the abutting position and limit a distance that the door panel assembly 120 moves in the first direction relative to the frame 110 to prevent the door panel assembly 120 from separating from the frame 110. The limiting member 1280 is used for avoiding the abutting member 1283 when in the avoiding position, so that the door panel assembly 120 can be separated from the frame 110 along the first direction.

The sample analyzer 100 provided by the embodiment of the present application can move between the abutment position for abutting against the abutting member 1283 to limit the distance of movement of the door panel assembly 120 relative to the rack 110 along the first direction and the avoidance position for avoiding the abutting member 1283 so that the door panel assembly 120 can be separated from the rack 110 along the first direction by making the door panel assembly 120 separable from the rack 110 along the first direction, and connecting one of the limiting member 1280 and the abutting member 1283 of the limiting structure 128 with the door panel assembly 120, and the other one with the rack 110.

After the door panel assembly 120 is mounted on the frame 110, the limit member 1280 is moved to the abutting position, so that the door panel assembly 120 is prevented from being separated from the frame 110 by being restricted from moving in the first direction, and the door panel assembly 120 is stably mounted on the frame 110. When door plant subassembly 120 is dismantled from frame 110 to needs, can make spacing part 1280 move to dodging the position from the butt position, at this moment, can make door plant subassembly 120 remove and with frame 110 separation along first direction, the operation is very simple, convenient, can save the time that door plant subassembly 120 dismantled and assembled.

It should be noted that, the connection between one of the limiting member 1280 and the abutting member 1283 and the door panel assembly 120, and the connection between the other of the limiting member 1280 and the abutting member 1283 and the frame 110 include two cases: 1. the limiting component 1280 is connected with the door panel assembly 120, and the abutting component 1283 is connected with the frame 110; 2. the position-limiting member 1280 is connected to the frame 110, and the abutting member 1283 is connected to the door panel assembly 120.

The stopper 1280 is configured to abut against the abutment member 1283 when the stopper 1280 is in the abutment position, and may be in an abutting state with the abutment member 1283 when the stopper 1280 is in the abutment position, or may be not yet abut against the abutment member 1283 when the stopper 1280 is in the abutment position, but after the door panel assembly 120 moves a certain distance in the first direction with respect to the frame 110, the stopper 1280 may abut against the abutment member 1283 and restrict the door panel assembly 120 from continuing to move in the first direction with respect to the frame 110, so as to prevent the door panel assembly 120 from separating from the frame 110 in the first direction.

In some embodiments, as shown in fig. 4 and 6, the stopping member 1280 includes a stopping portion 1281 configured to abut against the abutting member 1283, the stopping portion 1281 is located on a side of the abutting member 1283 opposite to the first direction, a distance between the stopping portion 1281 and the abutting member 1283 when the stopping member 1280 is in the abutting position in the first direction is H1, and a distance between the stopping portion 1281 and the abutting member 1283 when the stopping member 1280 is in the retreating position in the first direction is H2, wherein H1 < H2.

It can be understood that, by making the distance H1 in the first direction between the stopping part 1281 and the abutting part 1283 when the stopping part 1280 is in the abutting position smaller than the distance H2 in the first direction between the stopping part 1281 and the abutting part 1283 when the stopping part 1280 is in the avoiding position, when the stopping part 1280 is in the abutting position, the distance H1 in the first direction between the stopping part 1281 of the stopping part 1280 and the abutting part 1283 is smaller, even H1 is 0, at this time, if the door panel assembly 120 moves a smaller distance in the first direction relative to the rack 110, the stopping part 1281 of the stopping part 1280 will abut against the abutting part 1283 to limit the door panel assembly 120 from continuing to move in the first direction, thereby preventing the door panel assembly 120 from separating from the rack 110 in the first direction.

When the limiting component is located at the avoiding position, the distance H2 between the limiting part 1281 of the limiting component 1280 and the abutting component 1283 in the first direction is large, and at this time, if the door panel component 120 moves a large distance (as shown in fig. 7) along the first direction relative to the frame 110, the limiting part 1281 of the limiting component 1280 does not abut against the abutting component 1283, that is, the limiting component 1280 avoids the abutting component 1283, and the door panel component 120 can be separated from the frame 110 along the first direction.

In other embodiments, the stopping member 1280 includes a stopping portion 1281 configured to abut against the abutting member 1283, and when the stopping member 1280 is in the abutting position, the stopping portion 1281 is located on a side of the abutting member 1283 opposite to the first direction, and the stopping portion 1281 overlaps with the abutting member 1283 in the first direction. Therefore, when the door panel assembly 120 moves a small distance along the first direction relative to the frame 110, the position-limiting part 1281 of the position-limiting part 1280 abuts against the abutting part 1283 in the first direction to limit the door panel assembly 120 to continue moving along the first direction, thereby preventing the door panel assembly 120 from separating from the frame 110 along the first direction.

When the limiting member 1280 is in the avoiding position, the limiting member 1281 and the abutting member 1283 are staggered in the first direction (that is, the limiting member 1281 and the abutting member 1283 do not overlap in the first direction), so that the limiting member 1281 is avoided from the abutting member 1283. Therefore, when the door panel assembly 120 moves a large distance in the first direction with respect to the frame 110, the position-limiting part 1281 of the position-limiting member 1280 does not abut against the abutting member 1283 in the first direction, that is, the position-limiting member 1280 avoids the abutting member 1283, so that the door panel assembly 120 can be separated from the frame 110 in the first direction.

In some embodiments, as shown in fig. 4 and 5, the abutment member 1283 is connected to the frame 110. The stop member 1280 is pivotally coupled to the door panel assembly 120 such that the stop member 1280 is movable between an abutting position and an avoidance position. When the limiting component 1280 rotates relative to the door panel assembly 120, the limiting part 1281 of the limiting component 1280 moves in the first direction, so that when the limiting component 1280 is in the abutting position, the limiting part 1281 of the limiting component 1280 is close to the abutting component 1283 in the first direction, and the limiting part 1281 of the limiting component 1280 can abut against the abutting component 1283 to limit the door panel assembly 120 to be separated from the rack 110 along the first direction. When the limiting component 1280 is located at the avoiding position, the limiting part 1281 of the limiting component 1280 is away from the abutting component 1283 in the first direction, so that the limiting part 1281 of the limiting component 1280 can avoid the abutting component 1283, and the door panel assembly 120 can be separated from the rack 110 in the first direction.

Alternatively, when the stopper 1280 is rotated relative to the door panel assembly 120, the stopper 1281 of the stopper 1280 may be moved in a direction that forms an angle with the first direction, so that the stopper 1281 may be moved to a position that overlaps the contact member 1283 in the first direction, or to a position that is offset from the contact member 1283 in the first direction.

In other embodiments, the stop member 1280 is slidably coupled to the door panel assembly 120 such that the stop member 1280 is movable between an abutting position and an avoidance position. When the position limiting member 1280 slides relative to the door panel assembly 120, the position limiting portion 1281 of the position limiting member 1280 moves in the first direction, so that the position limiting portion 1281 of the position limiting member 1280 is close to or away from the abutting member 1283 in the first direction, and the position limiting portion 1281 of the position limiting member 1280 can abut against or avoid the abutting member 1283.

Alternatively, when the stopper 1280 slides relative to the door panel assembly 120, the stopper 1281 of the stopper 1280 moves in a direction that forms an angle with the first direction, and the stopper 1281 can move to a position that overlaps with the contact member 1283 in the first direction or a position that is offset from the contact member 1283 in the first direction.

In other embodiments, the abutment member 1283 is connected to the door panel assembly 120. The stop member 1280 is pivotally coupled to the frame 110 such that the stop member 1280 is movable between an abutting position and an avoidance position. When the limiting member 1280 is rotated relative to the frame 110, the limiting portion 1281 of the limiting member 1280 moves in the first direction, so that the limiting portion 1281 of the limiting member 1280 is close to or away from the abutting member 1283 in the first direction, and the limiting portion 1281 of the limiting member 1280 can abut against or avoid the abutting member 1283.

Alternatively, when the stopper 1280 is rotated relative to the frame 110, the stopper 1281 of the stopper 1280 may be moved in a direction forming an angle with the first direction, and the stopper 1281 may be moved to a position overlapping with the contact member 1283 in the first direction or to a position shifted from the contact member 1283 in the first direction.

In other embodiments, the stop member 1280 is slidably coupled to the frame 110 such that the stop member 1280 is movable between an abutting position and an avoidance position. When the limiting member 1280 slides relative to the frame 110, the limiting portion 1281 of the limiting member 1280 moves in the first direction, so that the limiting portion 1281 of the limiting member 1280 is close to or away from the abutting member 1283 in the first direction, and the limiting portion 1281 of the limiting member 1280 can abut against or avoid the abutting member 1283.

Alternatively, when the stopper 1280 is slid with respect to the frame 110, the stopper 1281 of the stopper 1280 may be moved in a direction forming an angle with the first direction, and the stopper 1281 may be moved to a position overlapping with the contact member 1283 in the first direction or to a position shifted from the contact member 1283 in the first direction.

In some embodiments, the stop 1280 is rotatable relative to the door panel assembly 120 or the frame 110 about an axis of rotation that is angled with respect to the first direction. Thus, when the position limiting member 1280 rotates relative to the door panel assembly 120 or the frame 110, the position limiting portion 1281 of the position limiting member 1280 may be moved in the first direction to make the position limiting portion 1281 approach the abutment member 1283 or move away from the abutment member 1283. Wherein the stop 1280 can be rotatably coupled to the door panel assembly 120. Alternatively, the position limiting member 1280 may be rotatably connected to the housing 110.

In other embodiments, the stop 1280 is angled relative to the first direction relative to the sliding direction of the door panel assembly 120 or the frame 110. Thus, when the position restricting member 1280 slides with respect to the door panel assembly 120 or the chassis 110, the position restricting portion 1281 of the position restricting member 1280 can be moved to a position overlapping the abutment member 1283 in the first direction or a position shifted from the abutment member 1283 in the first direction.

In the embodiment of the present application, the specific installation manner of the limiting member 1280 and the abutting member 1283 may be determined according to the structures of the rack 110 and the door panel assembly 120. In the opposite direction to the first direction, the stop member 1280 and the abutment member 1283 are located at one side of the hinge structure 127, as shown in fig. 5. Alternatively, the stop member 1280 and the abutment member 1283 are located on one side of the hinge structure 127 in the first direction. Only need make when spacing component 1280 is in the butt position can with butt component 1283 butt to restriction door plant subassembly 120 separates with frame 110 along first direction, and spacing component 1280 is in when dodging the position, can dodge butt component 1283, make door plant subassembly 120 can follow first direction and frame 110 separation can.

The limiting member 1280 and the connecting shaft 1272 are respectively connected to the door panel assembly 120, and the abutting member 1283 and the connecting member 1270 are respectively connected to the frame 110. The limiting member 1280, the abutting member 1283, the connecting member 1270 and the connecting shaft 1272 are sequentially distributed along the first direction. Thus, the connection shaft 1272 may be inserted into the connection hole of the connection member 1270 in the reverse direction of the first direction to mount the door panel assembly 120 on the chassis 110 in the reverse direction of the first direction. When the position-limiting member 1280 is at the abutting position, the position-limiting member 1280 can abut against the abutting member 1283 along the first direction to limit the moving distance of the door panel assembly 120 along the first direction, and prevent the door panel assembly 120 from separating from the rack 110 along the first direction.

Specifically, sample analyzer 100 includes an attachment socket 129 that is coupled to the housing 110. The connecting member 1270 and the abutting member 1283 are provided on the connecting base 129, the connecting shaft 1272 and the stopper 1280 are provided on the door panel assembly 120, and the connecting base 129 and the chassis 110 are connected, whereby the connecting member 1270 and the abutting member 1283 can be attached to the chassis 110.

Alternatively, the connecting member 1270 and the stopper 1280 are provided on the connecting base 129, and the connecting shaft 1272 and the abutment member 1283 are provided on the door panel assembly 120. Alternatively, the connecting shaft 1272 and the abutting member 1283 are provided to the connecting base 129, and the stopper 1280 and the connecting member 1270 are provided to the door panel assembly 120.

As shown in fig. 4 and 5, the sample analyzer 100 further includes a base 123, the base 123 is coupled to the door panel assembly 120 or the rack 110, and a retention member 1280 is mounted to the base 123 such that the retention member 1280 is mounted to the door panel assembly 120 or the rack 110. In some embodiments, the positioning member 125 is disposed on the base 123, and when the retention member 1280 is in the abutting position, the positioning member 125 is configured to apply a force to the retention member 1280 to maintain the retention member 1280 in the abutting position.

It can be understood that, when the limiting member 1280 is in the abutting position, the positioning member 125 applies an acting force to the limiting member 1280 to keep the limiting member 1280 in the abutting position, so that the limiting member 1280 can be stably limited to the door panel assembly 120, and the door panel assembly 120 can be prevented from being separated from the rack 110 in the first direction due to the movement of the limiting member 1280 from the abutting position to the avoiding position due to the vibration, shaking and the like of the sample analyzer 100.

In some embodiments, the positioning member 125 includes a magnetic member coupled to the base 123, the position-limiting member 1280 includes a magnetic-attracting portion 1282, and the magnetic-attracting portion 1282 and the magnetic member attract each other when the position-limiting member 1280 is in the abutting position. Thus, the magnetic member can apply a magnetic attraction force to the stopper 1280 to hold the stopper 1280 in the abutting position.

Wherein, the magnetic member can be a magnet or an electromagnet, and the magnetic part 1282 of the position-limiting member 1280 is made of iron, a magnet, an electromagnet, etc. magnetically attracted by the magnet or the electromagnet. Alternatively, the magnetic member may be iron, and the magnetic part 1282 of the position-limiting member 1280 may be a magnet, an electromagnet, or the like that can be magnetically attracted to the iron.

Specifically, the base 123 is mounted to the door panel assembly 120. The base 123 is mounted on the reinforcing plate 121 of the door panel assembly 120. The base 123 is welded to the reinforcing plate 121. The magnetic member may be attached to the base 123 by means of adhesion, snap fit, or the like. The base 123 includes two installation parts 1231 that set up relatively, and the stop component 1280 is located between two installation parts 1231, and the stop component 1280 is connected with two installation parts 1231 rotation through the connecting piece 124 to make the connection of stop component 1280 and base 123 more stable. The connecting member 124 includes a pin, a screw, a bolt, etc., which are not limited herein.

In other embodiments, the positioning member 125 comprises a resilient member coupled to the base 123 that is coupled to the stop member 1280 and applies a resilient force to the stop member 1280 to limit movement of the stop member 1280 from the abutting position to the retracted position. When the stop member 1280 is moved away from the abutment position by the shaking or vibration of the sample analyzer 100, the elastic force applied to the stop member 1280 by the elastic member can cause the stop member 1280 to automatically return to the abutment position.

The elastic member includes a torsion spring, a spring, rubber, and the like, and the elastic force applied by the elastic member to the limiting member 1280 may be a pushing force or a pulling force, which is specifically determined according to the type and the installation position of the elastic member.

In other embodiments, the positioning component 125 includes a positioning shaft movably connected to the base 123, the limiting component 1280 has a positioning hole, and the positioning shaft is inserted into the positioning hole when the limiting component 1280 is in the abutting position to limit the limiting component 1280 from moving to the avoiding position, so that the limiting component 1280 can be stably maintained in the abutting position. When the limiting component 1280 needs to move from the abutting position to the avoiding position, the positioning shaft can be withdrawn from the positioning hole to remove the limitation on the limiting component 1280, and then the door panel assembly 120 can be taken down from the rack 110 along the first direction by manually pushing the limiting component 1280 to move to the avoiding position.

In other embodiments, the positioning component 125 includes a snap structure connected to the base 123, and the snap structure is snapped to the stop component 1280 when the stop component 1280 is in the abutting position, so as to limit the movement of the stop component 1280, and thus the stop component 1280 can be stably maintained in the abutting position. When the limiting component 1280 needs to move from the abutting position to the avoiding position, a large pushing force can be applied to the limiting component 1280 manually, so that the limiting component 1280 is separated from the clamping state of the clamping structure, the limiting component 1280 can be pushed to move to the avoiding position, and the door panel assembly 120 is taken down from the rack 110 along the first direction.

Of course, the stop 1280 may be held in the abutting position by its own weight. Alternatively, by increasing the frictional force between the stopping member 1280 and the base 123, the stopping member 1280 is subjected to a large frictional force when moving from the abutting position to the avoiding position, so that the stopping member 1280 is held in the abutting position.
