Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a strip retraction mechanism and a testing instrument incorporating the mechanism. Background Technology
[0002] In various testing fields, testing instruments are widely used, and they often need to be paired with test strips to complete the corresponding testing items. For example, in many scenarios such as blood glucose testing and biochemical indicator testing, test strips play an important role as the key component for carrying and reacting test samples.
[0003] In existing testing instruments, the removal of test strips often relies on manual operation, which has the following drawbacks:
[0004] First, there are significant health and safety risks. During the testing process, the test strips come into contact with bodily fluids and other samples from the person being tested, which may carry various pathogens such as bacteria and viruses. When manually removing the strips, operators inevitably come into direct contact with them, which can easily lead to the spread of pathogens and expose them to the risk of infection. This is especially true in scenarios involving frequent testing, such as hospital laboratories and community testing sites, where the risk of infection increases significantly with the number of tests performed.
[0005] Secondly, the operation is inefficient. Manual strip removal requires operators to spend extra time and effort to carefully pull out the test strip. Moreover, in actual operation, due to reasons such as the test strip being installed tightly or being in an inconvenient position to grasp, the test strip is often difficult to remove smoothly. This further slows down the progress of the entire testing process and affects testing efficiency. Especially in situations where a large number of testing tasks need to be completed quickly, such as large-scale physical examination activities and disease screening sites, the inefficient manual strip removal method has become a bottleneck for the efficient conduct of testing work.
[0006] Third, it can easily damage the testing instrument. Manual operation has a high degree of uncertainty. During the manual removal of the test strip, improper force or angle deviation may cause the test strip to scratch or collide with precision components such as the internal slots and sensors of the testing instrument, affecting the normal service life and detection accuracy of the testing instrument, increasing the maintenance cost and replacement frequency of the equipment, and bringing unnecessary economic burden to the user.
[0007] In view of this, the present invention provides a new solution to the above problems. Utility Model Content
[0008] The purpose of this invention is to provide a strip removal mechanism and a testing instrument with the mechanism, which solves the problems of existing testing instruments lacking a strip removal mechanism, such as easy infection during manual strip removal, low efficiency, and easy damage to the equipment.

[0020] A testing instrument includes a testing instrument body and the aforementioned strip retraction mechanism.
[0021] A further preferred embodiment is that the tester body has a receiving groove, the spring is located in the receiving groove and one end is fixed to the fixing block, and the other end is fixed to the side wall of the receiving groove.

[0027] This utility model's strip ejection mechanism, through the coordinated operation of its various components, facilitates strip ejection for operators while protecting the equipment and test strips, and simultaneously improves the overall efficiency and quality of the testing process. This orderly mechanical ejection method also prevents the test strip from colliding or scratching with other precision components inside the tester during removal, protecting internal components such as slots and sensors from damage, maintaining the normal performance and lifespan of the tester, reducing maintenance costs and downtime due to equipment failure, ensuring the continuity and stability of the testing work, and avoiding the risk of infection from manual strip ejection.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings.
[0037] Example: A strip unwinding mechanism and a testing instrument incorporating the mechanism, such as... Figure 1-5 As shown, the strip retraction mechanism includes a connecting rod 2, a strip retraction push button 1, a connector 5, and a spring 31.
[0038] The push button 1 is used to move the connecting rod 2. A limit block 6 is fixed in the middle of the connecting rod 2. A cross groove is opened on the limit block 6, and the push button 1 is inserted into the cross groove. The push button 1 and the connecting rod 2 make contact in a cross shape, which is convenient for assembly and disassembly, and at the same time makes the structure more stable.
[0039] Preferably, the push button 1 has anti-slip stripes on the other side opposite to the limit block 6.
[0040] In the above technical solution, the design of inserting the strip retraction push button 1 into the "cross groove" of the limiting block 6 creates a stable and reliable connection structure between the strip retraction push button 1 and the connecting rod 2. On the one hand, the "cross groove" can limit the strip retraction push button 1 in multiple directions, ensuring that when the strip retraction push button 1 drives the connecting rod 2 to move, there will be no relative wobbling or misalignment between the two, thus ensuring the effective transmission of force. This allows the connecting rod 2 to move precisely in the expected direction when the operator pushes the strip retraction push button 1, thereby ensuring the stability and accuracy of the subsequent use of the connecting rod 2 to push related components to achieve the strip retraction function.
[0041] The anti-slip stripes on the opposite side of the retraction push button 1 relative to the limit block 6 significantly improve ease of use and operational reliability. These stripes increase the friction on the surface of the retraction push button 1, allowing the operator to grip it more firmly when manually operating it. Even under adverse conditions such as sweaty hands or a damp operating environment, slippage is less likely, greatly improving operational accuracy and convenience. This allows the operator to push the retraction push button 1 more easily and stably, ultimately ensuring the efficient and reliable operation of the entire retraction mechanism and enhancing the overall quality and efficiency of the retraction operation.
[0042] Reference Figure 1-5 Spring 31 is used to drive the connecting rod 2 to reset, so that after the operator releases the push button 1, the connecting rod 2 can automatically move in the opposite direction and return to its original position.
[0043] Preferably, a fixing block 32 close to the limiting block 6 is fixed on the connecting rod 2, the length direction of the spring 31 is consistent with the moving direction of the connecting rod 2, and the spring 31 is connected to the fixing block 32 and the testing instrument.
[0044] Specifically, a positioning post 33 is fixed on the fixing block 32, and a spring 31 is sleeved on the positioning post 33.
[0045] In the above technical solution, the design of using spring 31 to drive the connecting rod 2 to reset has several positive technical effects. First, when the operator releases the strip retraction push button 1, spring 31 can use its own elastic force to make the connecting rod 2 automatically move in the opposite direction and return to its original position. In this way, the entire strip retraction mechanism can quickly return to its initial state and be ready for the next strip retraction operation. This greatly improves the ease of use and operational efficiency of the strip retraction mechanism, avoids the tedious process of manual reset, and enables the testing work to be carried out more continuously and efficiently.
[0046] A fixed block 32 is fixed on the connecting rod 2, which is close to the limiting block 6. The length direction of the spring 31 is consistent with the moving direction of the connecting rod 2. At the same time, the spring 31 is connected to the fixed block 32 and the testing instrument. With this design, on the one hand, the fixed block 32 provides a stable and reliable connection point for the spring 31, ensuring that the force of the spring 31 can be accurately applied to the connecting rod 2 during the extension and retraction process. This makes the reset action of the connecting rod 2 precise and smooth, avoiding jamming or incomplete reset due to unstable connection, and ensuring the reliability of the entire strip retraction mechanism.
[0047] Specifically, a positioning post 33 is fixed on the fixed block 32, and the spring 31 is sleeved on the positioning post 33. This design further enhances the stability and functionality of the structure. The positioning post 33 can accurately position the spring 31, preventing the spring 31 from shifting or twisting laterally during extension and retraction. This ensures that the spring 31 always exerts its elastic force stably along the moving direction of the connecting rod 2, which not only extends the service life of the spring 31 but also makes the reset action of the connecting rod 2 more stable and repeatable. This further improves the overall stability of the unwinding mechanism and provides a strong guarantee for continuously and accurately completing the unwinding operation.
[0048] Reference Figure 1-5The connector 5 has a slot for positioning the test strip 4. During testing, the test strip 4 is inserted into the slot of the connector 5, and the test strip 4 is connected to the tester through the connector 5. The connector 5 includes a connector body 51, on which a terminal slider 53 is provided. The connecting rod 2 is used to push the terminal slider 53 to push the test strip 4 out of the connector 5.
[0049] Preferably, there are two connectors 5, which are located at both ends of the connecting rod 2 and are used to position different test strips 4.
[0050] Preferably, the bottom of the connecting rod 2 is provided with a limiting groove 7 that is adapted to the terminal slider 53, and the terminal slider 53 is cylindrical and inserted into the limiting groove 7.
[0051] Preferably, the connector body 51 has a groove 52, the length direction of which is consistent with the moving direction of the connecting rod 2, and the terminal slider 53 slides and engages with the connector body 51 along the length direction of the groove 52. The groove 52 is configured to pass through the slot.
[0052] Specifically, the terminal slider 53 is embedded in the slide groove 52 and slides with the slide groove 52. When the test strip 4 is inserted into the connector 5, the terminal slider 53 just contacts the end of the test strip 4.
[0053] In the above technical solution, connector 5 is used to position the test strip 4, ensuring that the test strip 4 remains stably and accurately positioned during testing. This guarantees a reliable connection between the test strip 4 and the testing instrument via connector 5, laying the foundation for accurate detection. During testing, the test strip 4 is inserted into connector 5, preventing it from shaking or shifting arbitrarily. This ensures the stability of signal transmission and the accuracy of the test results, avoiding detection errors or failures that may occur due to unstable positioning of the test strip 4.
[0054] A limiting groove 7 is provided at the bottom of the connecting rod 2 to fit the terminal slider 53. The terminal slider 53 is cylindrical and inserted into the limiting groove 7. This structural design brings good fit and mechanical transmission advantages. The limiting groove 7 plays a precise limiting role for the terminal slider 53, ensuring that the terminal slider 53 can move stably in the predetermined direction under the push of the connecting rod 2, avoiding deviation from the expected trajectory. This allows the force transmitted from the connecting rod 2 to act accurately and efficiently on the terminal slider 53, ensuring the reliability and accuracy of the pushing action, and providing a strong guarantee for the subsequent smooth ejection of the test strip 4 from the connector 5.
[0055] The groove 52 provides guidance and constraint for the movement of the terminal slider 53, ensuring that the terminal slider 53 moves strictly in a predetermined straight line during its movement. This further enhances the stability and accuracy of pushing the test strip 4, preventing unnecessary damage to the test strip 4 or failure to push it out smoothly due to unstable slider movement trajectory. Secondly, the design of the terminal slider 53 making just contact with the end of the test strip 4 ensures that when the connecting rod 2 pushes the terminal slider 53, the force can be directly and effectively transmitted to the test strip 4, achieving precise and smooth pushing of the test strip 4 out of the connector 5. This not only ensures the success rate of strip ejection operation but also helps extend the service life of the test strip 4 and the entire connector 5 structure, thus improving the overall performance of the strip ejection mechanism in terms of strip ejection function.
[0056] A testing instrument, such as Figure 6 , 7 As shown, the tester includes a tester body 8 and a strip retraction mechanism, which is located inside the tester body 8. A receiving groove 10 is provided inside the tester body 8. A spring 31 is located inside the receiving groove 10, with one end fixed to a fixing block 32 and the other end fixed to the side wall of the receiving groove 10.
[0057] Preferably, the tester body 8 is provided with a guide groove 9 for guiding the connecting rod 2 to move horizontally along the length direction of the spring 31. A retaining wall 12 is fixed on the connecting rod 2. The retaining wall 12 is located in the guide groove 9 and slides with the inner wall of the guide groove 9.
[0058] Preferably, the tester body 8 has a mounting opening 11 on its outer shell. The connecting rod 2 is located inside the tester body 8. One end of the strip retraction push button 1 is connected to the connecting rod 2, and the other end passes through the mounting opening 11 and is exposed outside the tester body 8. The strip retraction push button 1 is embedded in the mounting opening 11 and slides with the mounting opening 11 along the moving direction of the connecting rod 2.
[0059] In the above technical solution, the receiving groove 10 provides a dedicated space for the spring 31, which can effectively protect the spring 31 and prevent it from being interfered with by external factors during the extension and retraction process. For example, it can prevent the spring 31 from being accidentally collided, squeezed, or hooked by other parts, thereby ensuring that the spring 31 can stably and normally exert its elastic function and reliably realize its function of driving the connecting rod 2 to reset. At the same time, this fixing method ensures that both ends of the spring 31 have stable connection points, making the force transmission more stable and precise. During the movement and reset of the connecting rod 2, the spring 31 can extend and retract in the expected manner, without problems such as uneven elastic force or incomplete reset caused by unstable connection. This ensures the continuity and accuracy of the entire strip retraction mechanism and helps maintain the long-term stable strip retraction operation performance of the testing instrument.
[0060] The guide groove 9 provides precise guidance for the movement of the connecting rod 2, restricting it to horizontal movement only along the length of the spring 31. This prevents the connecting rod 2 from deviating from its intended direction when subjected to the pushing force of the strip removal button 1 or the restoring force of the spring 31, such as swaying up and down or tilting left and right. This ensures the accuracy and stability of the moving path of the connecting rod 2. The sliding fit between the retaining wall 12 and the inner wall of the guide groove 9 enhances the stability of the connecting rod 2 during movement, allowing it to slide smoothly along the trajectory defined by the guide groove 9. Furthermore, it makes the relative positional relationship between the connecting rod 2 and the testing instrument body 8 clearer and more fixed. This contributes to the rational layout and compact installation of the entire strip removal mechanism within the testing instrument, improving the overall integrity and reliability of the internal structure. It further ensures that the strip removal operation can be performed smoothly and accurately, reducing potential damage to other internal components or impact on the strip removal effect caused by unstable movement of the connecting rod 2.
[0061] A mounting port 11 is provided on the outer shell of the tester body 8, allowing one end of the strip retraction push button 1 to connect to the connecting rod 2, while the other end passes through the mounting port 11 and is exposed outside the tester body 8. The strip retraction push button 1 is embedded in the mounting port 11 and slides along the direction of movement of the connecting rod 2. This design brings positive effects in terms of both ease of use and structural rationality. From the perspective of ease of use, the strip retraction push button 1 being exposed outside the tester body 8 facilitates direct contact and operation by the operator, allowing the operator to easily activate the strip retraction mechanism by pushing the strip retraction push button 1 without the need for complex disassembly or additional operations of the tester. This conforms to the principles of ergonomics and improves the convenience and efficiency of operation. From the perspective of structural rationality, the sliding fit between the strip ejection push button 1 and the mounting port 11 ensures that the strip ejection push button 1 will not detach from the mounting port 11 or cause large shaking during the pushing process. It can only slide stably along the moving direction of the connecting rod 2, ensuring that the force applied by the operator can be accurately transmitted to the connecting rod 2. This ensures that the internal components of the strip ejection mechanism can move in an orderly manner according to the design requirements, improving the reliability and stability of the entire strip ejection mechanism. It also makes the appearance structure of the tester simpler and more reasonable, facilitating daily use and maintenance.
[0062] In summary, before testing, the test strip 4 is inserted into the connector 5. The connector 5's structural design allows for precise positioning of the test strip 4, ensuring a correct connection between it and the testing instrument, thus guaranteeing the smooth progress of subsequent testing. At this time, the connecting rod 2 in the strip ejection mechanism is in its initial position, the spring 31 is in its natural unforced state or its pre-compressed initial setting state, and the strip ejection push button 1 is also in its original, unoperated position. When the test is completed and the test strip 4 needs to be removed, the operator pushes the strip ejection push button 1. After the push button 1 is subjected to force, due to its connection with the connecting rod 2, it will drive the connecting rod 2 to move in the corresponding direction. As the connecting rod 2 moves, its end will contact the terminal slider 53 on the connector body 51 and apply a pushing force to the terminal slider 53. Under the push of the terminal slider 53, the test strip 4 will be smoothly ejected from the connector 5 along the predetermined path, completing the strip ejection operation. After the operator releases the strip retraction push button 1, the spring 31, which was originally in a compressed state, begins to push the connecting rod 2 in the opposite direction due to its elastic restoring force, causing the connecting rod 2 to move in the opposite direction to the strip retraction, gradually returning to its initial position. During the return process of the connecting rod 2, all components of the entire strip retraction mechanism also return to their initial state, preparing for the next strip retraction operation, thus allowing for repeated detection and strip retraction operations.
[0063] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
