Description

Technical Field

[0001] The utility model relates to a molecular diagnostic instrument, in particular to a reagent strip locking mechanism for a molecular diagnostic instrument. Background Art

[0002] For a molecular diagnostic instrument, the online management of reagent strips is the position where the human-machine interaction is the most frequent. It is required that the reagent strips can be replaced online in real time, and the used reagent strips can be replaced online without the instrument stopping. Since the reagent strips in the reagent storage are relatively dense (up to 20 can be stored), it is easy to take out the reagent strip that is being used by mistake during manual picking and placing, thus causing the instrument to stop. Therefore, the reagent storage of a molecular diagnostic instrument is usually equipped with a locking mechanism to lock the reagent strips to avoid reducing the probability of downtime caused by mis-taking. However, although the existing locking mechanism can lock and unlock the reagent strips, the state of the reagent strips remains unchanged. When it is necessary to replace the reagent strips, it is impossible to quickly identify the reagent strips that have been unlocked and need to be replaced, which increases the replacement time of the operator and there is also a possibility of missed replacement. Therefore, how to design an online management device that can quickly eject the reagent strips after unlocking the reagent strips is crucial for improving the replacement efficiency and avoiding missed replacement. Summary of the Invention

[0003] In view of this, the utility model provides a reagent strip locking mechanism for a molecular diagnostic instrument, which can be ejected after the reagent strip is unlocked, can realize quick identification, improve the replacement efficiency and avoid missed replacement.

[0004] To achieve the above object, the utility model adopts the following technical solutions:

[0005] The reagent strip locking mechanism for a molecular diagnostic instrument of the utility model includes a reagent strip rack for placing reagent strips and a locking structure arranged at the outlet end of the reagent strip rack, and further includes a plurality of ejection structures arranged at intervals on the bottom plate of the reagent strip rack. The ejection structures are arranged corresponding to the reagent strip positions on the bottom plate one by one. Each ejection structure includes a fixing member arranged on the bottom plate, a guiding member slidably penetrating through the fixing member, and an energy storage member. The energy storage member is sleeved on the guiding member outside the fixing member. Anti-disengagement members are arranged at both ends of the guiding member, and one of the anti-disengagement members abuts against the reinforcing rib at the bottom of the reagent strip.

[0006] The beneficial effects are as follows: The utility model installs an ejection structure on the bottom plate (i.e., the reagent strip position on the bottom plate) corresponding to the upper and lower parts of each reagent strip. The ejection structure adopts an energy storage type structure. When locked, the ejection structure is in an energy storage state. Once the reagent strip is unlocked, the energy stored in the ejection structure will be released, and then the reagent strip will be ejected, so that the reagent strip can be quickly identified, which is convenient for replacement and improves the replacement efficiency. In addition, the automatic ejection of the reagent strip can also avoid the situation of missed replacement and reduce the error rate.

[0007] Preferably, the fixing member is a fixing base fixed on the bottom plate, the guiding member is a guiding shaft penetrating through the fixing base, and the energy storage member is an energy storage spring sleeved on the guiding shaft. Among them, during actual installation, the fixing base can be a circular base or a rectangular base. In order to save materials, two fixing platforms can be processed on both sides of the circular base and the rectangular base, and the fixing platforms can be fixed on the bottom plate by bolts.

[0008] In a preferred embodiment of the present invention, the energy storage spring is a compression spring and is sleeved on the guiding shaft located on the right side of the fixing base. When the reagent strip is in the locked state, the compression spring is in a compressed state. Once the reagent strip is unlocked, the compression spring will push the reagent strip towards its handle direction through the anti-disengagement member at the end of the guiding shaft, making its handle protrude outwards from other reagent strips, thereby realizing quick differentiation, identification, and replacement.

[0009] In another preferred embodiment of the present invention, the energy storage spring is a tension spring and is sleeved on the guiding shaft located on the left side of the fixing base. One end of the tension spring is connected to the fixing base, and the other end is connected to the corresponding anti-disengagement member. In this embodiment, the tension spring is installed on the other side of the fixing base. In the locked state, the anti-disengagement member at the right end of the guiding shaft still abuts against the reinforcing rib, and the tension spring is in a stretched state. When the reagent strip is unlocked, the force released by the tension spring causes the guiding shaft to move to the right, thereby pushing the reagent strip out and making it protrude from other reagent strips, thereby realizing quick differentiation, identification, and replacement.

[0016] The following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings. These embodiments are implemented on the premise of the technical solution of the present utility model, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present utility model is not limited to the following embodiments.

[0017] It should be noted that in the description of the present utility model, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0018] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected" and "connected" may be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0019] As Figures 1-5 shown, the reagent strip locking mechanism for a molecular diagnostic instrument according to the present utility model includes a reagent strip holder 2 for placing reagent strips 1 (the reagent strips 1 are arranged side by side in the reagent strip holder 2), a locking structure 4 provided at the outlet end of the reagent strip holder 2 (corresponding to the reagent strips 1 one by one), and a plurality of ejection structures 3 spaced apart on the bottom plate 2.1 of the reagent strip holder 2. The ejection structures 3 and the reagent strips 1 are in one-to-one correspondence up and down, that is, an ejection structure is provided on the bottom plate 2.1 at the position corresponding to each reagent strip 1 (i.e., the reagent strip position).

[0020] The ejection structure 3 includes a fixing member (i.e., a fixing seat 3.1) provided on the bottom plate 2.1, a guiding member (i.e., a guiding shaft 3.2) slidably penetrating through the fixing seat 3.1, and an energy storage member (i.e., an energy storage spring 3.3). Both ends of the guiding shaft 3.2 are respectively located on both sides of the fixing seat 3.1, and an anti-detachment member (i.e., an anti-detachment head 3.4) is provided at each end of the guiding shaft 3.2 to prevent the guiding shaft 3.2 from sliding out of the fixing seat 3.1.

[0021] The energy storage spring 3.3 is provided on the guiding shaft 3.2 on the left or right side of the fixing seat 3.1, and the guiding shaft 3.2 is located on the left side of the reinforcing rib of the reagent strip 1. In the locked state, due to the limitation of the locking structure, the reagent strip 1 applies a leftward external force to the energy storage spring 3.3, and the energy storage spring 3.3 is in an energy storage state. After unlocking, the external force applied to the energy storage spring 3.3 disappears, and the energy storage spring 3.3 is released, thereby ejecting the reagent strip 1 out a certain distance, making it protrude from other reagent strips 1, thereby achieving rapid identification, facilitating replacement and avoiding missed replacement.

[0022] During actual installation, the energy storage spring 3.3 is a compression spring and is sleeved on the guide shaft 3.2 located on the right side of the fixed seat 3.1. When the reagent strip 1 is in the locked state, the guide shaft 3.2 is located on the left side of the reagent strip 1, and the reagent strip 1 applies a leftward force to the guide shaft 3.2, thereby causing the compression spring to be in a compressed state to achieve energy storage, as shown in Figure 3 ; after unlocking, the external force applied to the compression spring disappears, and the compression spring expands and then pushes the reagent strip 1 to the right (i.e., towards the handle direction) by a certain distance (see Figure 5 ), so that its handle protrudes from other reagent strips 1, realizing quick identification and improving the replacement efficiency.

[0023] Of course, the energy storage spring 3.3 can also be a tension spring sleeved on the guide shaft 3.2 located on the left side of the fixed seat 3.1 (see Figure 6 ). One end of the tension spring is connected to the fixed seat 3.1, and the other end is connected to the anti-disengagement part at the left end. When locking, the reagent strip 1 applies a leftward force to the guide shaft 3.2, causing the tension spring at its left end to be in a stretched state. After unlocking, the force released by the tension spring causes the guide shaft 3.2 to move to the right, and then pushes the reagent strip 1 to the right by a certain distance, making it protrude from other reagent strips 1, thereby realizing quick discrimination and replacement.

[0024] During actual installation, the fixed seat 3.1 can be a circular seat or a rectangular seat. To save materials, two fixing platforms can be processed on both sides of the circular seat and the rectangular seat, and the fixing platforms can be fixed to the bottom plate 2.1 using bolts.

[0025] Finally, it should be emphasized that the above description is only the preferred embodiment of the present invention and is not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still make modifications to the technical solutions described in the foregoing embodiments without creative efforts, or perform equivalent replacements for some of the technical features. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
