[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a detection box applied to a full-automatic blood culture instrument. Background Art

[0002] The blood culture instrument is a microbiological detection medical instrument that tests whether there are bacteria in blood samples. The instrument is very important for quickly testing whether there is bacterial growth in the blood of patients with sepsis and bacteremia, which seriously endanger the patients' lives, and for clarifying the diagnosis results.

[0003] At present, the basic principle of blood culture instrument testing is: inject the sample to be tested into the reagent bottle containing the culture medium, and then place the reagent bottle in the reagent bottle socket of the detection box under a constant temperature environment for incubation. During the incubation process, the detection box needs to be shaken continuously to prevent the blood in the reagent bottle from clotting. Finally, the sensor at the bottom of the reagent bottle socket detects whether there are microorganisms in the sample in the reagent bottle. Among them, the main functions of the detection box socket include positioning and clamping the reagent bottle.

[0004] At present, the reagent bottle clamping mechanism 02 used in the detection box of the blood culture instrument adopts independent spring pieces, and each reagent bottle socket 01 corresponds to a spring piece. When the reagent bottle 03 is placed in the reagent bottle socket 01 in the detection box, the reagent bottle 03 squeezes the spring piece, thereby firmly fixing the reagent bottle 03 in the detection box. Figure 1 and Figure 2 As shown, when the number of reagent bottle jacks 01 of the detection box is large, the assembly of the spring pieces takes a long time, and the assembly is extremely inconvenient when the above structure is adopted.

[0005] Therefore, how to overcome the above technical defects is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0010] Wherein, after assembly, the elastic bending edge of the reagent bottle clamping spring extends from the avoidance hole into the reagent bottle insertion hole.

[0011] Optionally, in the detection box of the above-mentioned blood culture instrument, one end of the elastic bending edge is bent and connected to the spring fixing surface, and the other end is provided with a protective bending edge, and the bending direction of the protective bending edge is facing away from the reagent bottle socket.

[0012] Optionally, in the detection box of the above-mentioned blood culture instrument, the connection between the protective bent edge and the elastic bent edge is a smooth transition.

[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] The core of the utility model is to provide a blood culture instrument and a detection box thereof, which can effectively improve the assembly efficiency of the reagent bottle clamping spring piece and the reagent bottle plug hole structure.

[0043] In order to enable those skilled in the art to better understand the technical solution provided by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] Specifically, please refer to Figure 3-Figure 9 The utility model provides a detection box for a blood culture instrument, comprising: a box body 201 and a reagent bottle clamping spring 1.

[0045] At least one row of reagent bottle insertion holes 202 is arranged on the box body 201, and the reagent bottle insertion holes 202 are used to place the reagent bottles 3 and realize the positioning of the reagent bottles 3. The number of the reagent bottle insertion holes 202 can be selected according to actual needs and is not further limited here.

[0046] The box 201 is provided with a plurality of avoidance holes on the mounting surface with the reagent bottle clamping spring piece 1, so that the mounting surface forms a hollow state. The avoidance holes correspond to the reagent bottle sockets 202 one by one. It should be noted that the reagent bottle sockets 202 on the box 201 can be arranged in one row, two rows, or even multiple rows. When the reagent bottle sockets 202 are in one row, a mounting surface and avoidance holes are arranged on any one side of the two sides of the box 201; when the reagent bottle sockets 202 are in two rows, mounting surfaces and avoidance holes are arranged on both sides of the box 201; and when the reagent bottle sockets 202 are in three rows or more, a mounting groove can be arranged on one side of the reagent bottle sockets 202 in the middle row of the box 201, and the mounting groove separates the reagent bottle sockets 202 in adjacent rows. The groove wall of the mounting groove is provided with a mounting surface and avoidance holes.

[0047] Each row of reagent bottle jacks 202 corresponds to at least one reagent bottle clamping spring 1, which includes a spring fixing surface 101 and a plurality of elastic bending edges 102. The spring fixing surface 101 is used to be installed on the mounting surface of the box 201, and the plurality of elastic bending edges 102 are connected to the spring fixing surface 101 and arranged at intervals. Figure 3 As shown, a short side of the elastic bending edge 102 is connected to the spring sheet fixing surface 101 by bending, so that the elastic bending edge 102 forms a cantilever relative to the spring sheet fixing surface 101, and the cantilever structure has a rebound performance. It should be noted that when the reagent bottle socket 202 is a row, in one case, the reagent bottle clamping spring sheet 1 can be used as one, and the elastic bending edge 102 on the reagent bottle clamping spring sheet 1 is consistent with the number on the reagent bottle socket 202. In another case, the reagent bottle clamping spring sheet 1 can be used in plurality, and the number of elastic bending edges 102 on each reagent bottle clamping spring sheet 1 is multiple, and the number of elastic bending edges 102 on all reagent bottle clamping spring sheets 1 is equal to the number on the reagent bottle socket 202; when the reagent bottle socket 202 is a plurality of rows, the setting mode of the reagent bottle clamping spring sheet 1 corresponding to each row of reagent bottle sockets 202 is consistent with the previous embodiment (when the reagent bottle socket 202 is a row).

[0048] Among them, the elastic bending edge 102 of the assembled reagent bottle clamping spring 1 extends into the reagent bottle insertion hole 202 through the avoidance hole. The elastic bending edge 102 of the reagent bottle clamping spring 1 is installed inside the reagent bottle insertion hole 202 and is used to clamp the reagent bottle 3. The clamping principle of the reagent bottle clamping spring 1 is that after the reagent bottle 3 contacts the elastic bending edge 102, the elastic bending edge 102 deforms to generate elastic force, clamping the reagent bottle 3, thereby ensuring that the reagent bottle 3 maintains a relatively fixed position relationship with the box body 201 during the movement of the detection box. The detection box monitors the changes in blood components in the reagent bottle 3 through the detection plate on the rear end surface to perform medical diagnosis.

[0049] The utility model provides a detection box for a blood culture instrument, wherein at least one row of reagent bottle insertion holes 202 are arranged on a box body 201, and a plurality of avoidance holes are provided on the mounting surface of the box body 201 with the reagent bottle clamping spring piece 1. Each row of reagent bottle insertion holes 202 corresponds to at least one reagent bottle clamping spring piece 1, and the reagent bottle clamping spring piece 1 includes a spring piece fixing surface 101 and a plurality of elastic bending edges 102. During assembly, the spring piece fixing surface 101 of each reagent bottle clamping spring piece 1 is installed on the mounting surface of the box body 201, and each elastic bending edge 102 can extend into the reagent bottle insertion hole 202 through the avoidance hole. After the reagent bottle 3 is placed in the reagent bottle insertion hole 202, the elastic bending edge 102 of the reagent bottle clamping spring piece 1 is deformed, and the deformed elastic bending edge 102 generates a radial thrust on the reagent bottle 3, thereby ensuring that the position of the reagent bottle 3 in the reagent bottle insertion hole 202 remains unchanged.

[0050] Compared with the assembly method in the prior art in which a reagent bottle clamping spring clip 1 is assembled into a reagent bottle socket 202, this solution arranges multiple elastic bending edges 102 on a single reagent bottle clamping spring clip 1, and at the same time arranges avoidance holes on the mounting surface of the box body 201, so that one reagent bottle clamping spring clip 1 can correspond to multiple reagent bottle sockets 202, which can effectively improve the assembly efficiency of the reagent bottle clamping spring clip 1 and the reagent bottle socket 202 structure.

[0051] In a specific embodiment, one end of the elastic bending edge 102 is bent and connected to the spring fixing surface 101, and the other end is provided with a protective bending edge 103, and the bending direction of the protective bending edge 103 is facing away from the reagent bottle insertion hole 202. The above design makes the bottle clamping spring include three parts: the spring fixing surface 101, multiple elastic bending edges 102 and the protective bending edge 103 at the end of the elastic bending edge 102, see Figure 3 and Figure 7 The connection between the elastic bending edge 102 and the protective bending edge 103 can be smooth, which can protect the reagent bottle 3 and prevent the reagent bottle 3 from being scratched during the process of inserting the reagent bottle 3 into the detection box, especially protecting the paper label attached to the reagent bottle 3.

[0052] In a specific embodiment, the spring fixing surface 101 and the elastic bending edge 102 of each reagent bottle clamping spring 1 are alternately arranged, and the length of the elastic bending edge 102 is greater than or equal to the length of the spring fixing surface 101. The spring fixing surface 101 is a planar structure, and bolt holes are provided at the relative positions of each spring fixing surface and the box body 201 to ensure that the spring is firmly and effectively fixed on the detection box. The reagent bottle clamping spring 1 and the box body 201 are connected by bolts 4.

[0053] like Figure 5 As shown, the reagent bottle clamping spring piece 1 is fixed to the upper and lower sides of the detection box by bolts 4, and is used to clamp the reagent bottle 3. The side of the box body 201 has avoidance holes and bolt holes to facilitate the installation of the reagent bottle clamping spring piece 1.

[0054] Furthermore, all bolt holes are round holes, and when round holes are used, the processing accuracy is required to be high. Alternatively, some of all bolt holes are round holes and the rest are strip holes, and the length direction of the strip holes is consistent with the direction of a row of reagent bottle sockets 202.

[0055] It should be noted that since the overall length of the reagent bottle clamping spring 1 is relatively long, and the design of the fixing hole on the spring fixing surface 101 must fully consider the matching tolerance, the reagent bottle clamping spring 1 structure of this scheme uses round holes for positioning, and other bolt holes all use strip holes to be compatible with the manufacturing tolerance of the detection box and facilitate installation.

[0056] In order to match more types of reagent bottles 3, the reagent bottle jack 202 can be a circular jack or a regular polygonal jack. The specific shape can be designed according to the shape of the reagent bottle 3 and the processing technology of the detection box, and is not limited to shapes such as circle, rectangle, regular pentagon or regular hexagon.

[0057] Preferably, the spring fixing surface 101 and the elastic bending edge 102 of each reagent bottle clamping spring 1 are formed by stamping or bending a piece of elastic plate.

[0058] A reagent bottle clamping spring 1 includes multiple elastic bent edges 102, which are installed on the side of the reagent bottle socket 202 of the detection box. The matching edges (installation surfaces) of the reagent bottle socket 202 and the reagent bottle clamping spring 1 are hollowed out, so that the elastic bent edges 102 of the reagent bottle clamping spring 1 can be extended into the reagent bottle socket 202. When the reagent bottle 3 is placed in the reagent bottle socket 202, the elastic bent edges 102 of the reagent bottle clamping spring 1 contact the reagent bottle 3 and produce elastic deformation. The reagent bottle clamping spring 1 produces radial elastic force on the reagent bottle 3, thereby playing a clamping role.

[0059] The reagent bottle clamping spring 1 is an integrated spring. In terms of structure, taking into account the shortcomings of a large number of reagent bottle clamping springs 1 and time-consuming assembly when assembling traditional reagent bottle clamping springs 1 in the detection box, this solution further optimizes the structure of the reagent bottle clamping spring 1 and the reagent bottle socket 202, thereby reducing the number of reagent bottle clamping springs 1 required for assembling the detection box.

[0060] Specifically, the reagent bottle clamping spring piece 1 is made of elastic sheet metal material and needs to have a high hardness. After the reagent bottle clamping spring piece 1 is deformed, an effective radial elastic force is generated. The elastic force generated after the elastic deformation can also be changed by adjusting the bending angle of the elastic bending edge 102. Of course, the reagent bottle clamping spring piece 1 can also be made into an integral spring piece by using elastic plastic materials or other methods.

[0061] In summary, in view of the problem that the reagent bottle sockets 202 and the reagent bottle clamping springs 1 in the detection box of the current blood culture instrument need to be configured one-to-one, the number of reagent bottle clamping springs 1 is large, and the installation is time-consuming, an integral reagent bottle clamping spring 1 and a reagent bottle socket 202 matching it are developed. One reagent bottle clamping spring 1 corresponds to multiple reagent bottle sockets 202, and at the same time, the structure of the box 201 is adaptively improved. The reagent bottle socket 202 structure is only hollowed out on the side, and is used in conjunction with the reagent bottle clamping spring 1. The reagent bottle socket 202 has a simple structure, and the reagent bottle clamping spring 1 is easy to assemble, thereby saving the material quantity and assembly time of the reagent bottle clamping spring 1.

[0062] In addition, the utility model also provides a blood culture instrument, including the detection box in the above embodiment. The blood culture instrument is a microbiological detection medical instrument for detecting whether there are bacteria in the blood sample. The instrument is very important for quickly detecting whether there are bacteria growing in the blood of patients with sepsis and bacteremia that seriously endanger the patient's life clinically, and for clarifying the diagnosis result. The detection box is the core component of the blood culture instrument, which is used for fixing the reagent bottle and detecting the components.

[0063] Obviously, the blood culture instrument with the above-mentioned detection box has the same beneficial effects, which will not be described in detail here.
