Description

Technical Field

[0001] This utility model relates to the field of medical reagent bottle protection, specifically a medical reagent bottle protection device. Background Technology

[0002] Protective devices for medical reagent bottles are crucial auxiliary equipment in medical settings, ensuring the safe storage of reagents and preventing contamination. Their core function is to achieve the orderly storage of reagent bottles (such as glass reagent bottles, sample tubes, and urine collection catheters) through structural design, while simultaneously blocking external contamination and the transmission of pathogens. This is especially important for reagent bottles storing biological samples, which require additional protection against cross-infection caused by residual pathogens from the sample via instruments, hands, and the human body / other instruments. Urine collection catheters, as dedicated reagent bottles for storing urine samples, are particularly susceptible to the adhesion of residual pathogens from patient urine (such as Escherichia coli, Staphylococcus epidermidis, and even pathogenic microorganisms like Neisseria gonorrhoeae and SARS-CoV-2). These pathogens can be transferred through hand contact, and if subsequent disinfection is not thorough, infection can easily occur through hand-to-mouth, hand-to-eye contact, or contact with other patients / instruments.

[0003] In practice, users are instinctively drawn to ease of use and tend to prioritize storing their samples in holes without surrounding catheters. This often results in a random and disordered storage situation. Users then have to repeatedly search for empty holes, inevitably causing their hands to scrape and touch the outer wall of the stored catheter, directly coming into contact with residual bacteria. Bacteria can be transferred again through hand contact, posing a risk of cross-infection. Therefore, a medical reagent bottle protection device is needed to solve this problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a protective device for medical reagent bottles, which solves the problem of cross-infection caused by hands coming into contact with bacteria on the outer wall of the reagent bottle when the reagent bottle is placed inside.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a medical reagent bottle protective device, including a storage rack body with a plurality of linearly arranged holes, a strip groove is provided at the top of the storage rack body, and a protruding part of a flexible cover is slidably connected in the groove, the protruding part is located on both sides of one end of the flexible cover, and the other end of the flexible cover is wound in the receiving compartment by a coil spring.

[0006] A trigger plate is slidably connected inside the main body of the storage rack. The trigger plate includes a contact part that extends into the hole. An internal spring is fixedly connected between the other end of the trigger plate and the cavity inside the main body of the storage rack. An L-shaped blocking plate is fixedly connected to one side of the trigger plate. One end of the blocking plate extends into the strip groove to block the protrusion of the flexible cover. When the protrusion of the flexible cover is blocked, the side of the flexible cover with the protrusion is between the two holes.

[0007] Preferably, a row-changing mechanism is installed between the holes closest to the coil spring on two adjacent rows on the main body of the storage rack. The row-changing mechanism includes a locking rod, a return spring, and a central shaft. The central shaft is fixedly connected to the main body of the storage rack and passes through the locking rod. The locking rod can rotate around the central shaft through the return spring. The locking rod includes a long handle and a short handle. The short handle is located on the travel path of the trigger plate, while the long handle is used to restrict the movement of the corresponding row of flexible cover plates.

[0008] By adopting the above technical solution, disorderly storage across rows is prevented: the row-changing mechanism is installed between the holes of the coil springs in two adjacent rows. Only when the last reagent tube in the upper row is inserted, the trigger plate squeezes the short handle end of the locking rod, driving the locking rod to rotate and unlock the lower row, thus avoiding accidental triggering of row changing.

[0009] Preferably, the protruding portion of the flexible cover plate is arc-shaped at the end furthest from the coil spring.

[0010] By adopting the above technical solution, when restoring the initial state, the arc-shaped surface can smoothly squeeze the blocking plate corresponding to each hole, avoiding the jamming caused by the direct rigid collision between the protruding part and the blocking plate.

[0011] Preferably, the contact portion of the trigger plate is configured as an arc shape.

[0012] By adopting the above technical solution, the reagent tube contacts the bottle wall through the arc surface when inserted, avoiding scratches on the outer wall of the glass reagent bottle and plastic sample tube due to the sharp contact surface, reducing the risk of reagent leakage. The arc surface contact can smoothly transmit the squeezing force of the reagent tube, pushing the trigger plate to retract into the storage rack body and preventing the trigger plate from jamming.

[0013] Preferably, a hollow shaft is fixedly connected inside the receiving chamber, a reel is sleeved on the hollow shaft, and a coil spring is installed between the reel and the hollow shaft.

[0014] By adopting the above technical solution, the coiling wheel rotates around the hollow shaft via the coiling spring, which can prevent the coiling spring from shifting or twisting during winding / unwinding, thus extending the service life of the coiling spring.

[0015] Preferably, a reset handle is fixedly connected to the top of the flexible cover.

[0016] By adopting the above technical solution, the flexible cover plate can be quickly reset by manually pulling it, which is convenient and quick without the need to disassemble the device.

[0017] Preferably, the flexible cover plate that the changing mechanism abuts has a slot adapted to the locking rod.

[0018] By adopting the above technical solution, the lock bar can be prevented from accidentally disengaging due to vibration or slight impact.

[0019] Compared with the prior art, this utility model has the following advantages: the flexible cover normally blocks unused holes, leaving only the first hole open. When the reagent bottle is inserted, the trigger plate is squeezed to unlock the blocking plate, so that the flexible cover unlocks the next hole simultaneously with the insertion of the test tube. The user can directly insert the reagent bottle in sequence without having to find an empty hole. At this time, the hand only touches the reagent bottle being operated, and the range of hand movement is fixed in the "area where no reagent bottle has been stored". It will not pass by or scratch the previously stored reagent bottle, cutting off the transfer of germs from the source of operation and greatly reducing the risk of cross-infection.

[0027] like Figures 1-6 As shown, a medical reagent bottle protective device includes a storage rack body 1 with a plurality of linearly arranged holes. A strip groove 2 is provided at the top of the storage rack body 1. A protruding part 301 of a flexible cover plate 3 is slidably connected in the groove. The protruding part 301 is located on both sides of one end of the flexible cover plate 3. The other end of the flexible cover plate 3 is wound into a receiving chamber 5 by a coil spring 4. A hollow shaft 10 is fixedly connected inside the receiving chamber 5. A coiling wheel 11 is sleeved on the hollow shaft 10. A coil spring 4 is installed between the coiling wheel 11 and the hollow shaft 10 to prevent the coil spring 4 from shifting or twisting during winding / unwinding, thus extending its service life.

[0028] A trigger plate 6 is slidably connected inside the main body 1 of the storage rack. The trigger plate 6 includes a contact part that extends into the hole. The contact part of the trigger plate 6 is arc-shaped. When the reagent tube is inserted, it contacts the bottle wall through the arc surface, avoiding scratches on the outer wall of the glass reagent bottle or plastic sample tube due to the sharp contact surface, reducing the risk of reagent leakage. The arc surface contact can smoothly transmit the squeezing force of the reagent tube, pushing the trigger plate 6 to retract into the main body 1 of the storage rack, preventing the trigger plate 6 from getting stuck. The other end of the trigger plate 6 is fixed to the cavity inside the main body 1 of the storage rack. A built-in spring 7 is connected, and an L-shaped blocking plate 8 is fixedly connected to one side of the trigger plate 6. One end of the blocking plate 8 extends into the strip groove 2 to block the protrusion 301 of the flexible cover plate 3. When the protrusion 301 of the flexible cover plate 3 is located between two holes, the end of the protrusion 301 of the flexible cover plate 3 away from the coil spring 4 is set in an arc shape. When returning to the initial state, the arc surface can smoothly press the blocking plate 8 corresponding to each hole, avoiding the jamming caused by the direct rigid collision between the protrusion 301 and the blocking plate 8. A row-changing mechanism 9 is installed between the holes closest to the coil springs 4 in two adjacent rows on the main body 1. The row-changing mechanism 9 includes a locking rod 901, a return spring 902, and a central shaft 903. The central shaft 903 is fixedly connected to the storage rack main body 1 and passes through the locking rod 901. The locking rod 901 can rotate around the central shaft 903 through the return spring 902. The locking rod 901 includes a long handle and a short handle. The short handle is located on the travel path of the trigger plate 6, while the long handle is used to restrict the movement of the corresponding row of flexible cover plates 3 to prevent disorderly storage across rows. Release: The row-changing mechanism 9 is installed between the holes of two adjacent rows near the coil spring 4. Only when the last reagent tube in the upper row is inserted, the trigger plate 6 presses the short handle end of the locking rod 901, driving the locking rod 901 to rotate and unlock the lower row, thus avoiding accidental triggering of the row-changing mechanism. The flexible cover plate 3 that the row-changing mechanism 9 abuts has a slot that fits the locking rod 901, thus preventing the locking rod 901 from accidentally disengaging due to vibration or slight collision. The top of the flexible cover plate 3 is fixedly connected to a reset handle 12, which can be manually pulled to quickly reset the flexible cover plate 3 without disassembling the device, which is convenient and quick.

[0029] When using

[0030] In the initial state, the first row of flexible cover plates 3 moves towards the direction of the coiling spring 4 under the elastic recoil action of the coiling spring 4, as... Figure 2 As shown, at this time, the protruding part 301 of the flexible cover plate 3 is blocked by the blocking plate 8 and stops moving, revealing the first hole. The remaining rows of flexible cover plates 3 are all locked by the long handle end of the locking rod 901 of the row changing mechanism 9 and cannot slide. Therefore, all the holes in the remaining rows are covered by the flexible cover plates 3 and cannot be used in advance.

[0031] When a reagent tube is inserted into the first exposed hole in the first row, the outer wall of the reagent tube presses against the arc-shaped portion of the trigger plate 6, pushing the trigger plate 6 to retract into the storage rack body 1. Simultaneously, the trigger plate 6 drives the portion of the blocking plate 8 extending into the strip groove 2 to retract, compressing the built-in spring 7. After the blocking plate 8 retracts, it releases its obstruction of the protruding portion 301 of the flexible cover plate 3. Under the elastic winding force of the coiling spring 4, the flexible cover plate 3 moves along the strip groove 2 towards the coiling spring 4 until it is blocked by the blocking plate 8 corresponding to the next hole. At this point, the next hole in the first row is automatically exposed for subsequent reagent tube insertion. Figure 6 As shown, the coil spring 4 serves as a power connector, with its inner end fixed to the hollow part of the hollow shaft 10 and its outer end fixed to the inner side wall of the coil wheel 11. The flexible cover plate 3 is wound onto the coil wheel 11 and housed in the receiving chamber 5 under the elastic winding action of the coil spring 4. The winding process is similar to the principle of a measuring tape. The above operation is repeated: "insert reagent tube → squeeze trigger plate 6 → unlock cover plate → reveal the next hole". The reagent tube is gradually inserted into the remaining holes in the first row until all holes in the first row are filled with reagent tubes.

[0032] When the reagent tube is inserted into the last hole of the first row, such as Figure 4 During the process of the trigger plate 6 being squeezed and retracted, it will simultaneously squeeze the short handle of the locking rod 901 of the changing mechanism 9: Under the squeezing force at the short handle, the locking rod 901 rotates around the central axis 903, and the reset spring 902 is stretched; as the locking rod 901 rotates, its long handle end disengages from the slot of the next row of flexible cover plates 3, releasing the lock on the lower row of flexible cover plates 3. After the lower row of flexible cover plates 3 is unlocked, it is consistent with the initial state of the first row. Under the action of the pre-tightening force of its own coil spring 4, it moves towards the coil spring 4, and its protruding part 301 is blocked by the corresponding blocking plate 8, automatically exposing the first hole of the lower row. At this time, the lower row can insert reagent tubes according to the storage process of the first row.

[0033] When a reagent tube needs to be retrieved, the reagent tube in the target hole is pulled out. The trigger plate 6, which was originally squeezed and retracted by the reagent tube, returns to its initial position under the elastic restoring force of the built-in spring 7. The trigger plate 6 simultaneously drives the blocking plate 8 to extend into the strip groove 2, returning to the state where it can block the protrusion 301 of the flexible cover plate 3. When the reagent tube in the last hole of each row is retrieved, in addition to the above actions, the row changing mechanism 9 will also be triggered. The trigger plate 6 no longer squeezes the short handle of the locking rod 901 of the row changing mechanism 9. The originally stretched locking rod 901 return spring 902, under the action of elastic restoring force, drives the locking rod 901 to rotate around the central axis 903 to contact the next row of flexible baffles.

[0034] To restore the initial state; when restoring the first row, grasp the reset handle 12 at the top of the flexible cover 3 and pull it away from the coil spring 4 along the strip groove 2. At this time, the flexible cover 3 overcomes the coiling force of the coil spring 4 and gradually unfolds from the roller 11 in the receiving compartment 5. Since the end of the protrusion 301 of the flexible cover 3 away from the coil spring 4 is arc-shaped, during the process of pulling and resetting, the arc-shaped surface will smoothly squeeze the blocking plate 8 corresponding to each hole, pushing the blocking plate 8 back into the storage rack body 1, avoiding the jamming caused by the direct collision between the protrusion 301 and the blocking plate 8, ensuring that the flexible cover 3 can smoothly cover all holes. At this time, the blocking plate 8 of each hole has an internal spring. When the spring 7 is activated, the device resets and re-blocks the protrusion 301 of the flexible cover plate 3. At this time, the handle is released, and the first row of devices returns to its initial state where only the first hole is exposed and the remaining holes are completely closed. When the remaining rows return to their initial state, when the flexible cover plate 3 covers all the holes, the long handle end of the row changing mechanism 9, under the elastic restoring force of the reset spring 902, drives the locking rod 901 to rotate around the central axis 903, re-blocking the empty groove of the flexible cover plate 3 and restoring the locking state of these rows. The remaining rows of flexible cover plates 3 are completely constrained and cannot slide, covering all the holes. The entire device returns to its initial state and a new round of reagent tube storage and placement can begin.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
