Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical technology, and in particular to an automatic device for identifying foreign objects in liquid medicine. Background Technology

[0002] After bottled liquid medicines are bottled, they must undergo a strict inspection process for impurities. This step is crucial for ensuring the quality of the medicines. It is necessary to test whether naturally occurring impurities in the liquid exceed the prescribed standards, and to check for foreign matter that may have been mixed in during the preparation process, such as tiny particles, fibers, or other contaminants.

[0003] Chinese patent CN211402783U discloses a liquid medicine visible foreign matter inspection station, including a tabletop and an inspection chamber. The inspection chamber includes a top plate, a back plate, a bottom plate, a left side plate, and a right side plate. A lighting lamp is installed on the inner wall of the top plate. The top plate consists of a flat plate and an inclined plate. The flat plate is parallel to the tabletop and perpendicularly connected to the back plate. The inner wall of the back plate is divided into two symmetrical areas, one white and the other black. A vertical plate is installed on the side of the bottom plate closest to the tabletop, and a long tubular bottom light is installed on the inner side of the vertical plate. The height of the vertical plate is sufficient to block the direct light from shining on the inspector. Using this liquid medicine visible foreign matter inspection station, a weak, variable light source can be simply added from the bottom of the sample, thereby quickly identifying visible foreign matter suspended in the liquid medicine, greatly improving the efficiency of liquid medicine visible foreign matter inspection and significantly reducing the eye strain and fatigue of the inspector.

[0004] However, since some bottled medicines are colored, and the color difference varies depending on the impurities contained in the medicine, quality inspectors need to wear different colored glasses to check for specific impurities in a particular medicine. Wearing colored glasses for a long time to observe the medicine and the surrounding objects can cause great damage to the eyesight of the staff and easily lead to visual fatigue. Therefore, those skilled in the art have proposed an automatic device for identifying foreign objects in medicines. Utility Model Content

[0005] In the existing technology, some bottled medicines are colored, and the color difference varies depending on the impurities contained in the medicine. This requires quality inspectors to wear different colored glasses to check for specific impurities in a particular medicine. However, wearing colored glasses for a long time to observe the medicine and the surrounding objects can cause great damage to the eyesight of the staff and easily lead to visual fatigue.

[0006] To solve the above problems, the present invention adopts the following technical solution: An automatic foreign object detection device for liquid medicine includes a base with self-locking wheels at its bottom; a connector comprising a shaft rotatably connected to the base and a connecting handle fixedly connected to the top of the shaft; a gear seat with a mounting groove in its center, the gear seat being rotatably connected to the outside of the connecting handle via the mounting groove; a support member disposed at the top of the connecting handle for holding the medicine bottle to be detected; a detection component comprising a transmitter and a receiver disposed on opposite sides of the support member; a lifting component disposed on the top of the gear seat for synchronously raising and lowering the transmitter and receiver; and a drive component disposed on the top of the base for rotating the gear seat.

[0007] In a preferred embodiment of the present invention, the carrier includes a support frame fixedly connected to the top of the connecting handle, the support frame having an inner cavity in the middle, and a lighting lamp installed in the inner cavity, and an anti-slip lens embedded in the top of the support frame.

[0008] In a preferred embodiment of the present invention, the lifting component includes two sets of lead screws rotating on the top of the gear seat. The bottom ends of the two sets of lead screws pass through the gear seat and are fixedly connected to a transmission wheel. The two sets of transmission wheels are connected by a belt drive. An L-shaped plate is fixedly connected to the bottom of the gear seat. A drive motor is fixedly installed on the outer side of the L-shaped plate. The output end of the drive motor passes through the L-shaped plate and is fixedly connected to one of the sets of transmission wheels.

[0009] In a preferred embodiment of the present invention, two sets of guide rods are fixedly connected to the top of the gear seat. Movable blocks are threadedly connected to the outer sides of both sets of lead rods. The movable blocks slide along the outer side of one set of guide rods. Mounting plates are fixedly connected to the outer sides of the movable blocks. The transmitting end and the receiving end are installed on the outer sides of the corresponding two sets of mounting plates.

[0015] Furthermore, firstly, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation on this utility model. Secondly, the term "a" should be understood as "at least one" or "one or more," that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple. The term "a" should not be construed as a limitation on the quantity.

[0016] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations are possible without departing from the stated principles.

[0017] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] Example 1: As attached Figure 1 To be continued Figure 6As shown, this utility model provides an automatic identification device for foreign objects in liquid medicine, including a base 1, with a self-locking wheel at the bottom of the base 1; a connector 2, which includes a shaft 201 rotatably connected to the base 1 and a connecting handle 202 fixedly connected to the top of the shaft 201; a gear seat 3, with a mounting groove 301 in the middle, and the gear seat 3 is rotatably connected to the outside of the connecting handle 202 through the mounting groove 301; a carrier 4, which is located at the top of the connecting handle 202 and is used to place the medicine bottle to be detected; a detection component 5, which includes a transmitter and a receiver, which are respectively located on opposite sides of the carrier 4; a lifting component 6, which is located on the top of the gear seat 3 and is used to drive the transmitter and receiver to lift synchronously; and a driving component 7, which is located on the top of the base 1 and is used to drive the gear seat 3 to rotate.

[0019] During use, medical staff first manually shake the medicine bottle to be tested to fully suspend impurities in the liquid. Then, they place the bottle stably on top of the carrier 4. If medical staff observe impurities, they can directly determine that impurities are present in the liquid. If medical staff cannot clearly determine the impurities with the naked eye, they turn on the transmitter and receiver in the detection component 5. The transmitter emits a specific wavelength of ultraviolet light, and the receiver captures the wavelength and intensity of the transmitted ultraviolet light in real time through a spectral sensor. Because the absorption and transmission characteristics of pure medicine liquid for ultraviolet light are stable, a fixed reference spectrum is formed. When impurities are present in the liquid, the impurities will produce additional ultraviolet light. Scattering, absorption, or reflection of light causes the wavelength distribution of transmitted light to deviate from the reference spectrum. The detection component 5 compares the wavelength fluctuation data acquired by the receiver with a preset threshold. If the fluctuation exceeds the threshold, the liquid is determined to contain impurities. At the same time, the lifting component 6 is activated, causing the transmitter and receiver of the detection component 5 to reciprocate around the height of the medicine bottle. Then, the drive component 7 is activated, driving the gear seat 3 to rotate. During the rotation of the gear seat 3, the detection component 5 is simultaneously driven to rotate around the circumference of the medicine bottle, thereby achieving full detection of the medicine at different heights and angles inside the medicine bottle, thus greatly ensuring the accuracy of the equipment in judging impurities.

[0020] Example 2: As attached Figure 2 As shown, this embodiment is basically the same as the previous embodiment, except that the carrier 4 includes a support frame 401 fixedly connected to the top of the connecting handle 202. The support frame 401 has an inner cavity in the middle, and a lighting lamp 402 is installed in the inner cavity. The top of the support frame 401 is inlaid with an anti-slip lens 403.

[0021] Medical staff shake the medicine bottle to be tested, then place the bottle on the anti-slip lens 403 on top of the support frame 401. They then turn on the inner light 402. The light emitted by the light 402 passes through the anti-slip lens 403 and shines directly onto the medicine bottle, making the impurities in the medicine liquid inside the bottle more likely to glow under the light. Medical staff can visually observe whether there are glowing impurities in the medicine bottle to make a preliminary judgment on whether the medicine liquid contains impurities.

[0022] Example 3: As attached Figure 3 To be continued Figure 6 As shown, this embodiment is basically the same as the previous embodiment, except that the lifting component 6 includes two sets of lead screws 601 rotating on the top of the gear seat 3. The bottom ends of the two sets of lead screws 601 pass through the gear seat 3 and are fixedly connected to transmission wheels 602. The two sets of transmission wheels 602 are connected by a belt 603. An L-shaped plate 604 is fixedly connected to the bottom of the gear seat 3. A drive motor 605 is fixedly installed on the outer side of the L-shaped plate 604. The output end of the drive motor 605 passes through the L-shaped plate 604 and is fixedly connected to one of the transmission wheels 602. Two sets of guide rods 606 are also fixedly connected to the top of the gear seat 3. The outer sides of the two sets of lead screws 601 are threaded with movable... Block 607 and movable block 607 slide along the outside of one set of guide rods 606. The outside of movable block 607 is fixedly connected to mounting plate 608. The transmitter and receiver are installed on the outside of the corresponding two sets of mounting plates 608. Pressure detectors 609 are provided on the upper and lower sides of mounting plate 608. Two sets of baffles 610 are fixedly connected to the outside of guide rod 606. The drive component 7 includes an L-shaped plate 701 fixedly connected to the top of base 1. A drive motor 702 is fixedly installed at the bottom of L-shaped plate 701. The output end of drive motor 702 passes through L-shaped plate 701 and is fixedly connected to a transmission gear 703. The transmission gear 703 meshes with gear seat 3.

[0023] Start the drive motor 605, which drives the connected transmission wheel 602 to rotate. This, via belt 603, causes another set of transmission wheels 602 to rotate synchronously. The two sets of transmission wheels 602 drive the corresponding lead screw 601 to rotate. When the lead screw 601 rotates, the movable block 607 slides smoothly along the guide rod 606, thereby causing the transmitter and receiver to rise and fall synchronously via the mounting plate 608. When the pressure detector 609 on the mounting plate 608 touches the baffle 610 on the guide rod 606, the drive motor 605 reverses its direction. The reciprocating motion of the detection component 5 around the height of the medicine bottle is achieved by rotating the drive motor 702 of the drive component 7. The drive motor 702 drives the transmission gear 703 to rotate. The transmission gear 703 meshes with the gear seat 3, causing the gear seat 3 to rotate around the connecting handle 202. During the rotation of the gear seat 3, the lifting component 6 and the detection component 5 rotate synchronously around the circumference of the medicine bottle. Through the coordinated operation of reciprocating lifting and circumferential rotation, the medicine in the medicine bottle is fully detected from multiple angles, ensuring the accuracy and comprehensiveness of impurity detection.

[0024] Working principle: Medical staff shake the medicine bottle to be tested, then place the bottle on the anti-slip lens 403 on top of the support frame 401. Next, they turn on the internal lighting lamp 402. The light emitted by the lamp 402 passes through the anti-slip lens 403 and shines directly onto the medicine bottle, making impurities in the medicine liquid more likely to glow under the light. Medical staff visually inspect the medicine bottle for glowing impurities to make a preliminary judgment on whether the medicine liquid contains impurities. Then, they turn on the transmitter and receiver in the detection component 5, and simultaneously turn on the drive... A drive motor 605 and a drive motor 702 are configured. Drive motor 605 drives the connected transmission wheel 602 to rotate, which in turn drives the other set of transmission wheels 602 to rotate synchronously via belt 603. The two sets of transmission wheels 602 drive the corresponding lead screw 601 to rotate. When the lead screw 601 rotates, the movable block 607 slides smoothly along the guide rod 606, thereby driving the transmitter and receiver to rise and fall synchronously via mounting plate 608. When the pressure detector 609 on mounting plate 608 touches the baffle 610 on guide rod 606, the drive... The first motor 605 rotates in reverse, enabling the detection component 5 to reciprocate around the height of the medicine bottle. The second motor 702 drives the transmission gear 703 to rotate, and the transmission gear 703 meshes with the gear seat 3, causing the gear seat 3 to rotate around the connecting handle 202. During the rotation of the gear seat 3, the lifting component 6 and the detection component 5 rotate synchronously around the circumference of the medicine bottle. The transmitting end emits a specific wavelength of ultraviolet light, and the receiving end captures the wavelength and intensity of the transmitted ultraviolet light in real time through a spectral sensor. Since the absorption and transmission characteristics of pure medicine liquid are stable, a fixed reference spectrum is formed. When impurities are present in the medicine liquid, the impurities will cause additional scattering, absorption, or reflection of ultraviolet light, causing the wavelength distribution of the transmitted light to deviate from the reference spectrum. The detection component 5 compares the wavelength fluctuation data obtained by the receiving end with a preset threshold. If the fluctuation exceeds the threshold, the medicine liquid is determined to "contain impurities". Through the coordinated operation of the lifting component 6, the driving component 7, and the detection component 5, the medicine in the medicine bottle is fully detected from multiple angles, ensuring the accuracy and comprehensiveness of impurity detection.

[0025] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
