Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments are used to further describe the cuvette holder and the sample analysis device according to the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.
Referring to fig. 5 to 8, a reaction cup holder 10 according to an embodiment of the present invention includes: the support body 100, offer the reaction cup groove 200 on the frame face 110 of the support body 100, the reaction cup groove 200 is used for holding the reaction cup 300.
Support tables are respectively arranged at two ends of the notch 210 of the reaction cup groove 200, namely a first support table 120 and a second support table 130, a first flange 310 and a second flange 320 are respectively arranged on the reaction cup 300 corresponding to the first support table 120 and the second support table 130, and when the reaction cup groove 200 accommodates the reaction cup 300, the first support table 120 supports the first flange 310, and the second support table 130 supports the second flange 320, so that the reaction cup 300 is put on between the first support table 120 and the second support table 130.
The first support 120 is provided with a sliding surface 121, and when the reaction cup groove 200 accommodates the reaction cup 300, the sliding surface 121 abuts against the first flange 310, so that the reaction cup 300 has a sliding trend. This is because the first flange 310 is caught on the sliding surface 121 when the cuvette 300 is placed in the cuvette tank 200, and the cuvette 300 tends to slide downward due to its own weight and slightly deforms both the first flange 310 and the sliding surface 121 when in a stable state (the gravity of the cuvette 300 is balanced with the upward friction force received).
Referring to fig. 4, the reaction cup 300 is generally in the shape of a hollow cuboid with one end open, and comprises a bottom 301, two opposite end cup walls 302 and two opposite side cup walls 303, wherein the cup opening is generally rectangular. Referring to fig. 5, the corresponding cuvette slot 200 is a cuvette slot 200 having a rectangular cross section and a certain slot depth, comprising two opposite end inner walls 201 and two opposite side inner walls 202. The two ends of the notch 210 of the reaction cup slot 200 are respectively provided with a first supporting table 120 and a second supporting table 130, and the cup mouth position of the reaction cup 300 or the cup wall position near the cup mouth is provided with a first flange 310 and a second flange 320, which respectively correspond to the first supporting table 120 and the second supporting table 130. As shown in fig. 4, the two ends of the rectangular cup mouth of the reaction cup 300 are respectively provided with the first flange 310 and the second flange 320, one end surface cup wall 302 corresponds to the first flange 310, and the other end surface cup wall 302 corresponds to the second flange 320. In other embodiments, the reaction cup 300 may also have a circumferentially extending annular flange at or near its rim, i.e., two opposing side walls 303 of the reaction cup 300 may also have flanges. When the reaction cup 300 is accommodated in the reaction cup groove 200, the annular flanges correspond to the first support base 120 and the second support base 130 and are respectively a first flange 310 and a second flange 320.
The sliding surface 121 may be a flat surface, a concave arc surface, a convex arc surface, or the like, as long as it has a tendency to slide down the reaction cup 300 when it abuts the first flange 310. In one embodiment, the sliding surface 121 is planar, and the sliding surface 121 is inclined at an angle of 10 ° to 60 ° with respect to the horizontal. By designing the sliding surface 121 to be a plane and the angle at which the plane is inclined from the horizontal to be 10 to 60, it is easier to put the cuvette 300 in a stable state.
The first support 120 is provided with a sliding surface 121, and when the reaction cup 300 is accommodated in the reaction cup groove 200, the sliding surface 121 abuts against the first flange 310 to enable the reaction cup 300 to slide downwards. It can be understood that the reason why the cuvette 300 is shaken is that the cuvette 300 is moved upward in a vertical direction. When the reaction cup 300 is accommodated in the reaction cup holder 10, the downward sliding surface 121 inclined downward relative to the horizontal plane can make the reaction cup 300 not easy to shake. This is because when the reaction cup 300 is moved upward in the vertical direction due to shaking, the reaction cup 300 receives a downward contact friction force by the frictional contact between the first flange 310 and the sliding surface 121, and the reaction cup 300 is not easily shaken due to the combined resistance of the gravity and the contact friction force. If the first flange 310 is placed on a horizontal surface, the cuvette 300 is not subjected to a downward contact friction. The reaction cup support 10 can prevent the reaction cup 300 from shaking in the reaction cup groove 200, and does not need to add additional parts such as an elastic sheet, thereby avoiding uncertain factors caused by adding parts such as the elastic sheet, and having high reliability.
The manner of disposing the sliding surface 121 may be various. As one embodiment, as shown in fig. 5 and 6, the lower slide surface 121 is inclined in the width direction of the notch 210; when the reaction cup 300 is accommodated in the reaction cup groove 200, the side inner wall 202 of the reaction cup groove 200 abuts against the side of the reaction cup 300 to prevent the reaction cup 300 from sliding down. It will be appreciated that when the reaction cup 300 is provided with a first flange 310 and a second flange 320 only at both ends of its rim, the side of the reaction cup 300 refers to the side cup wall 303 of the reaction cup 300, i.e. one of the side cup walls on the reaction cup 300. When the reaction cup 300 is provided with an annular flange in its rim circumference, the side of the reaction cup 300 refers to the side flange of the reaction cup 300, i.e. the flange corresponding to one of the side cup walls 303 on the reaction cup 300. The sliding surface 121 is disposed on the first support base 120 in an inclined manner along the width direction of the notch 210, and when the reaction cup 300 is placed on the first support base 120 via the first flange 310, the first flange 310 abuts against the sliding surface 121, so that the reaction cup 300 has a sliding tendency, and the whole reaction cup 300 slightly slides down until the side portion of the reaction cup 300 abuts against the side portion inner wall 202 of the reaction cup groove 200. Thus, the first flange 310 is supported by the first support table 120, the second flange 320 is supported by the second support table 130, and the inner wall of the reaction cup groove 200 is abutted against the side of the reaction cup 300, so that the reaction cup 300 is put into the reaction cup groove 200 between the first support table 120 and the second support table 130, and the reaction cup 300 can be stably accommodated in the reaction cup groove 200 finally.
Referring to fig. 5 to 8, in one embodiment, the first support stand 120 is further provided with a relief portion 122, where the relief portion 122 and the lower sliding surface 121 are disposed opposite to each other in the width direction of the slot 210, and a relief space is formed between the relief portion 122 and the lower sliding surface 121. When the reaction cup groove 200 accommodates the reaction cup 300, the sliding surface 121 abuts against the first edge 311 of the first flange 310, so that the second edge 312 of the first flange 310 is suspended (see fig. 6) and the first edge 311 is opposite to the second edge 312. By arranging the avoiding part 122 to form an avoiding space, when the reaction cup 300 slightly slides down to the position where the side cup wall 303 of the reaction cup 300 is abutted against the side inner wall 202 of the reaction cup groove 200, the second edge 312 of the first flange 310 is suspended and is not in contact with the bracket body 100, so that better contact between the side cup wall 303 of the reaction cup 300 and the side inner wall 202 of the reaction cup groove 200 is ensured. Since the side wall 303 of the reaction cup 300 has a large contact area with the side inner wall 202 of the reaction cup tank 200 and many contact points, the reaction cup 300 can be stably accommodated in the reaction cup tank 200 and is not easy to shake. The escape portion 122 may be a right angle groove provided opposite to the lower slide surface 121, and an escape space may be formed between the right angle groove and the lower slide surface 121.
It will be appreciated that, as described in the background art, the gap between the walls of the cuvette 300 and the cuvette slot 200 is small, and thus the sliding down distance of the cuvette 300 is necessarily also short. The entire reaction cup 300 is slightly slid down a certain distance, and the second flange 320 at the other end of the reaction cup 300 may have various states. The second flange 320 of the reaction cup 300 may be in contact with the inner wall of the reaction cup groove 200 at the side of the reaction cup 300 after moving down a certain distance along with the reaction cup 300, and the second flange 320 and the second support 130 are also in contact with each other, and together with the first flange 310, support the reaction cup 300 on the reaction cup groove 200. If the reaction cup 300 is directly placed at a position where the side cup wall 303 of the reaction cup 300 is just in contact with the inner wall of the reaction cup groove 200 at the time of placement, the reaction cup 300 may hardly slip down and directly deform slightly at a position in contact with the holder body 100.
With continued reference to fig. 5 and 6, in some embodiments, the second support 130 may be provided with a second sliding surface 131, where the second sliding surface 131 abuts the second flange 320. The second sliding surface 131 may be inclined in the width direction of the slot 210, and the second sliding surface 131 may also be inclined in the length direction of the slot 210. Referring to fig. 5 and 6, the second sliding down surface 131 is inclined in the width direction of the slot 210, which coincides with the inclination direction of the sliding down surface 121. In other embodiments, the second sliding surface 131 is inclined in an opposite direction to the sliding surface 121.
In the embodiment shown in fig. 5 to 8, the sliding surface 121 is inclined in the width direction of the slot 210, the second sliding surface 131 is also inclined in the width direction of the slot 210, and the second sliding surface 131 is inclined in the same direction as the sliding surface 121. When the cuvette 300 is put on the lower slide surface 121 and the second lower slide surface 131, the entire cuvette 300 slightly slides down until the side wall 303 of the cuvette 300 abuts against the side inner wall 202 of the cuvette tank 200. Thus, the first support base 120 supports the first flange 310, the second support base 130 supports the second flange 320, and the side inner wall 202 of the cuvette holder 200 abuts against the side wall 303 of the cuvette 300, so that the cuvette 300 is placed in the cuvette holder 200 between the first support base 120 and the second support base 130, and the cuvette 300 can be stably contained in the cuvette holder 200.
As another embodiment, the lower slide surface 121 is inclined along the length direction of the slot 210; when the reaction cup 300 is accommodated in the reaction cup 300 groove 200, the second support 130 supports the second flange 320 to block the reaction cup 300 from sliding down. The sliding surface 121 is obliquely arranged on the first supporting table 120 along the length direction of the notch 210, when the reaction cup 300 is put on the first supporting table 120 through the first flange 310, the first flange 310 is abutted against the sliding surface 121, the reaction cup 300 has a sliding trend due to the gravity of the reaction cup 300, and the whole reaction cup 300 slightly slides down until the second flange 320 is put on the second supporting table 130, so that the reaction cup 300 can be finally stably accommodated in the reaction cup groove 200. During the process of sliding down the reaction cup 300, the second flange 320 may be directly moved down to abut against the second support 130. In some embodiments, the second support 130 may be provided with a second sliding surface 131, and the second sliding surface 131 abuts the second flange 320.
In some embodiments, the second sliding surface 131 may be inclined in the width direction of the slot 210. In other embodiments, the second sliding surface 131 may also be inclined along the length of the slot 210.
Referring to FIG. 9, a simplified cross-sectional view of one embodiment of a cuvette 300 along the length of the slot 210 while in the cuvette slot 200 is shown. In the case where the sliding surface 121 is inclined along the length direction of the slot 210 and the second sliding surface 131 is inclined along the length direction of the slot 210, the sliding surface 121 and the second sliding surface 131 are inclined toward the slot 210, and when the reaction cup 300 is mounted on the sliding surface 121 and the second sliding surface 131, the sliding surface 121 and the second sliding surface 131 which are inclined downward with respect to the horizontal plane can make the reaction cup 300 not easy to shake. This is because the reaction cup 300 is subject to downward contact friction due to the frictional contact between the first flange 310 and the sliding down surface 121 and the frictional contact between the second flange 320 and the second sliding down surface 131, and the reaction cup 300 is not easily shaken by the combined resistance of the gravity and the contact friction.
Of course, in some embodiments, as shown in fig. 10, a schematic cross-section of the cuvette 300 along the length direction of the slot 210 when in the cuvette slot 200 according to another embodiment, the second support 130 does not need the second sliding surface 131, but is stepped. When the reaction cup 300 is placed on the first support base 120 via the first flange 310, the first flange 310 is in contact with the lower slide surface 121. When the reaction cup 300 is placed on the second support 130 via the second flange 320, the second flange 320 is placed on the step.
As an embodiment, the second support table 130 has the same structure as the first support table 120, and the first support table 120 and the second support table 130 form plane symmetry with each other. Referring to fig. 5 to 8, it can be understood that when the first support stand 120 has the sliding down surface 121 inclined in the width direction of the slot 210, the second support stand 130 also has the second sliding down surface 131 inclined in the width direction of the slot 210, and the sliding down surface 121 and the second sliding down surface 131 are oriented in unison. The first support base 120 is provided with a relief portion 122, and the second support base 130 is also provided with a relief portion 122. In other embodiments, when the first support table 120 is provided with a bearing surface 123 (as will be mentioned in the following embodiments), the second support table 130 is also provided with a bearing surface 123. When the first support stand 120 has the lower sliding surface 121 inclined along the length direction of the slot 210, the second support stand 130 also has the second lower sliding surface 131 inclined along the length direction of the slot 210, and both the lower sliding surface 121 and the second lower sliding surface 131 are inclined toward the slot 210.
By designing the second support 130 to have the same structure as the first support 120, and making the first support 120 and the second support 130 form plane symmetry with each other, the reaction cup 300 is not only stably accommodated in the reaction cup slot 200, but also more convenient for one-time processing and forming of the reaction cup slot 200 when the reaction cup slot 200 is processed on the bracket body 100.
Referring to fig. 11 and 12, fig. 11 is a simplified schematic view of one embodiment of the reaction cup 300 in the reaction cup tank 200, and fig. 12 is a simplified schematic view of another embodiment of the reaction cup 300 in the reaction cup tank 200, wherein the dotted surrounding part represents the cup body part of the reaction cup 300 shielded by the holder body 100. As another embodiment, the first support table 120 may be further provided with a bearing surface 123, the bearing surface 123 and the sliding surface 121 being disposed opposite to each other in the width direction of the slot 210, the sliding surface 121 being inclined in the width direction of the slot 210.

By providing the support surface 123 on the opposite side of the slide-down surface 121, the first flange 310 can be placed in a substantially V-shaped groove formed by the slide-down surface 121 and the support surface 123 (as shown in fig. 11, when the support surface 123 is a plane inclined with respect to the horizontal plane) when the cuvette 300 is accommodated in the cuvette groove 200, and both side edges of the first flange 310 are brought into contact with the slide-down surface 121 and the support surface 123, respectively, to thereby form friction. So that the cuvette 300 can be stably accommodated in the cuvette slot 200. In other embodiments, see FIG. 12, the bearing surface 123 may also be stepped to support the second edge 312 of the first flange 310.
An embodiment of the present invention also provides a sample analyzer, which includes the cuvette holder 10 described above. The sample analyzer may be a coagulation analyzer, or other sample analyzer. The cuvette holder 10 may be a long-strip-shaped cuvette holder 10. A plurality of reaction cup grooves 200 may be provided at intervals along the longitudinal direction of the reaction cup holder 10 on the holder surface 110 of the holder body 100.
