[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] The following is combined with Figures 1-4 This invention describes the detection structure and thromboelastography instrument of this utility model.

[0024] like Figure 1 and Figure 2As shown, in an embodiment of this utility model, the detection structure includes: a housing, a driving mechanism, a swinging mechanism, a heating element 40, and a carrier cup 50. The driving mechanism, swinging mechanism, and heating element 40 are all disposed within the housing, which has a first through hole 111. The carrier cup 50 is disposed within the first through hole 111. The carrier cup 50 is used to hold a cup containing a test sample. In this embodiment, the carrier cup 50 can be a cup structure with a bottom surface or a conical structure without a bottom surface. When the carrier cup 50 is a conical structure without a bottom surface, the shape of the cup matches the shape of the carrier cup 50, and the size of the cup is slightly larger than the size of the carrier cup 50, so that the cup and the carrier cup 50 engage. In this embodiment, the test sample is a blood sample.

[0025] A heating element 40 is fitted onto the outside of the support cup 50 to heat the test sample. The first end of the swing mechanism is connected to the support cup 50, and a driving mechanism drives the swing mechanism to swing. When the swing mechanism swings, it can cause the support cup 50 and the cup body to swing together within the first through hole 111. In an optional embodiment of this invention, the swing mechanism can be an L-shaped swing rod. The driving mechanism includes a rotary motor and a pair of gears, the pair of gears meshing, the rotating shaft of the rotary motor connected to one gear, and one end of the L-shaped swing rod connected to the other gear. When the rotary motor reciprocates, it drives the L-shaped swing rod to rotate, thereby causing the support cup 50 to swing back and forth. In another optional embodiment, the swing mechanism includes a swing rod and an elastic element. The two ends of the elastic element are respectively connected to the housing and the swing rod. The driving mechanism includes a rotary motor and a cam. The cam is rolledly connected to the swing rod. When the cam rotates, it can drive the swing rod to swing, thereby causing the support cup 50 to swing within the first through hole 111.

[0026] The detection structure provided in this embodiment of the utility model has each carrier cup driven to swing by a separate drive mechanism. When the drive mechanism fails, only the carrier cup associated with that drive mechanism cannot be used, and it will not affect other carrier cups, thus ensuring detection efficiency. By installing a heating plate on the outer sleeve of the carrier cup, the swing function and heating function of the detection structure can be integrated together, simplifying the structure of the detection structure and reducing the size of the thromboelastography instrument.

[0027] like Figure 2As shown, in an embodiment of this utility model, the driving mechanism includes a driver 31 and a cam 32, with the driver 31 connected to the cam 32. The second end of the swing mechanism is elastically connected to the housing. The swing mechanism has a protrusion, which is rolledly connected to the cam 32. When the cam 32 rotates, when the highest point of the cam 32 abuts against the protrusion, the swing mechanism drives the bearing cup 50 to swing to one side. When the highest point of the cam 32 passes the protrusion, the protrusion abuts against the cam 32 under the action of elastic force, and the swing mechanism drives the bearing cup 50 to swing to the other side, so as to realize that the bearing cup 50 swings back and forth at a preset angle. Optionally, in an embodiment of this utility model, the driver 31 is a rotary motor.

[0028] like Figure 2 As shown, in an embodiment of this utility model, the swing mechanism includes: a swing rod 21, a swing block 22, and a first elastic member 23. The two ends of the swing rod 21 are respectively connected to the first elastic member 23 and the bearing cup 50, and the first elastic member 23 is connected to the housing. The swing block 22 is sleeved on the outside of the swing rod 21, and the swing block 22 forms a protrusion of the swing mechanism.

[0029] Specifically, the first elastic element 23 is used to drive the swing block 22 to move closer to the cam 32 when the cam 32 passes the swing block 22 at its highest point, so that the swing block 22 abuts against the cam 32, thereby... Figure 2 For example, in Figure 2 In the case where the swing rod 21 is horizontally disposed inside the housing, one end of the first elastic element 23 should be connected to the left side wall of the housing, and the first elastic element 23 is disposed at an angle to the swing rod 21. Optionally, the first elastic element 23 can be a spring.

[0030] like Figure 2 As shown, in this embodiment of the present invention, the detection structure further includes a push rod 71 and a second elastic member 72. The housing has a second through hole, which is opposite to the first through hole. The push rod 71 passes through the second through hole and extends outside the housing. The second elastic member 72 is sleeved on the outside of the push rod 71. In this embodiment, the bearing cup 50 has a hollow structure. Part of the push rod 71 is sleeved inside the bearing cup 50, and the portion above the push rod 71 inside the bearing cup 50 is used to accommodate the cup body. In this embodiment, the cup body and the bearing cup 50 are engaged to achieve synchronous swinging. When disassembling the cup body, disassembly is difficult because the cup body is embedded inside the bearing cup 50. Pushing the push rod 71 upwards can push the cup body out of the bearing cup 50, thus easily disassembling the cup body. After the cup body is removed, the push rod 71 returns to its original position under the action of the second elastic member 72.

[0031] Furthermore, in an embodiment of this utility model, a bearing is sleeved on the outer wall of the bearing cup 50. The bearing is located inside the first through hole 111 and can swing together with the bearing cup 50 within the first through hole 111.

[0032] like Figure 1 As shown, in an embodiment of this utility model, the housing includes a first housing 11 and a second housing 12, which are detachably connected. The first housing 11 has a first through hole 111, and the bearing cup 50 and the bearing are located within the first through hole 111. The second housing 12 has a second through hole, and a portion of the push rod 71 is located within the second through hole. The driver 31 and the heating element 40 are located within the second housing 12, while the swing rod 21, the swing block 22, and the cam 32 are located within the first housing 11.

[0033] like Figure 3 As shown, the first housing 11 contains a first mounting plate 113 and a second mounting plate 114. The second mounting plate 114 is horizontally positioned, and the rotation shaft of the driver 31 passes through the second mounting plate 114 and is connected to the cam 32. The two ends of the first mounting plate 113 are respectively connected to the top surface of the first housing 11 and the second mounting plate 114. One end of the first elastic element 23 is connected to the swing rod 21, and the other end is connected to the end face of the first mounting plate 113. The direction of the elastic force of the first elastic element 23 is consistent with the swing direction of the swing block 22.

[0034] In this embodiment of the invention, one side of the housing is an open end; that is, after the first housing 11 and the second housing 12 are snapped together, one side is open. The detection structure also includes a connecting plate 80, which is disposed at the open end. In this embodiment, the connecting plate 80 can close the open end, thereby forming a closed space inside the housing.

[0035] like Figure 2 As shown, the detection structure also includes a circuit board 90, which is electrically connected to the driver 31 and the heating element 40. The circuit board 90 controls the driver 31 and the heating element 40 to operate or stop operating via a through-hole circuit board 90. In embodiments of this utility model, the circuit board 90 can be positioned in various ways. When the connecting plate 80 closes the open end of the housing, the circuit board 90 can be placed on the connecting plate 80; when the connecting plate 80 does not close the open end of the housing, the circuit board 90 can be spliced ​​with the connecting plate 80 to close the open end of the housing. This arrangement helps to reduce the volume of the detection structure, thereby reducing the volume of the thromboelastography instrument.

[0036] like Figure 4 As shown in the embodiment of this utility model, the detection structure further includes a washer 60. The surface of the first housing 11 is provided with an annular groove 112, which is located outside the first through hole 111. A portion of the washer 60 is embedded within the annular groove 112. When the cup is placed inside the carrier cup 50, the washer extends to the upper part of the cup to buffer and dampen vibrations during the cup's swinging motion.

[0037] This utility model embodiment also provides a thromboelastography instrument, including: a third housing, multiple cups, and multiple detection structures. The multiple detection structures are disposed within the third housing, with the support cup 50 of each detection structure exposed outside the third housing. The support cup 50 is engaged with the cup body to achieve synchronous swinging. In this embodiment, each detection structure can independently detect the sample; if any detection structure malfunctions, it will not affect the other detection structures, ensuring detection efficiency.

[0038] Furthermore, each detection structure includes: a housing, a drive mechanism, a swing mechanism, a heating element 40, and a support cup 50. The drive mechanism, the swing mechanism, and the heating element 40 are all disposed within the housing, which has a first through hole 111. The support cup 50 is disposed within the first through hole 111 and is capable of swinging within the first through hole 111.

[0039] In actual testing, the cup containing the blood sample is snapped into the carrier cup 50, and the test needle is inserted into the blood sample. The drive mechanism drives the swing mechanism to swing back and forth, which in turn drives the carrier cup 50 and the cup body to swing back and forth in the first through hole 111. When the carrier cup 50 and the cup body swing, the heating plate 40 heats the blood sample simultaneously. As the blood sample gradually coagulates from liquid to solid, the test needle, which is covered by the blood sample, also swings, thereby realizing the process of blood coagulation or fibrinolysis.

[0040] The thromboelastography instrument provided in this embodiment of the invention features multiple detection structures, each capable of independently detecting blood samples. A malfunction in any detection structure will not affect the others, ensuring detection efficiency. Furthermore, the integrated design of the oscillation mechanism and heating element in each detection structure reduces the volume of the detection structure, thereby reducing the overall size of the thromboelastography instrument.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
