Description

Technical Field

[0001] The invention relates to the technical field of intelligent detection instruments, in particular to a high-frequency oscillator for freeze-dried powder injection vials. Background Art

[0002] Lyophilized powder injections are usually stored in vials, which are sealed with rubber stoppers. In order to investigate whether the key quality indicators of lyophilized powder injections will change abnormally when the vials are in contact with the rubber stoppers for a long time, the vials need to be oscillated so that the lyophilized powder injections in the sample can be in full contact with the rubber stopper of the vial as much as possible without destroying the integrity and sealing of the vial and ensuring that the physical properties of the lyophilized powder injections remain unchanged. However, existing oscillators can usually only oscillate a single position of the vial, resulting in uneven oscillation of the lyophilized powder injections inside the vial. To this end, we proposed a high-frequency oscillator for lyophilized powder injection vials. Summary of the invention

[0003] The present invention provides a high-frequency oscillator for a freeze-dried powder injection vial, which is not only convenient for fixing and installing the vial, but also can automatically oscillate the vial evenly and comprehensively, and has higher oscillation efficiency.

[0007] Wherein: a controller is provided on the front side of the shell, the input end of the controller is electrically connected to an external power supply, and the input end of the high-frequency vibrator is electrically connected to the output end of the controller, which is convenient for the fixed installation of the vial and can automatically oscillate the vial. The oscillation of the vial is more uniform and comprehensive, and the oscillation efficiency is higher, which can make the freeze-dried powder injection inside the vial fully contact with the rubber stopper at the lower end of the vial.

[0008] Furthermore, the rotating mechanism includes a fixed ring, a transmission gear, a gear ring and a connecting rod. The fixed ring is symmetrically rotatably connected to the outer side of the placing tube through a bearing. The outer side of the placing tube is provided with a gear ring, and the gear ring is located between the two fixed rings. The upper end of the connecting rod is rotatably connected to the inner walls of the mounting openings vertically corresponding to the two fixed rings. The upper ends of the two connecting rods are respectively provided with transmission gears meshing with the gear rings. The lower ends of the connecting rods are respectively inserted into the inside of the rotating sleeves on the same side. The lower ends of the rotating sleeves are provided with driven gears. A motor is provided in the middle of the upper surface of the partition. The lower end of the output shaft of the motor is provided with a driving gear meshing with the driven gear. The input end of the motor is electrically connected to the output end of the controller, which is convenient for driving the syringe bottle to rotate and making the lyophilized powder injection inside the syringe bottle oscillate more evenly.

[0009] Furthermore, the lower end of the connecting rod is a hexagonal rod body, and the upper end of the rotating sleeve is provided with a hexagonal socket that matches the connecting rod.

[0010] Furthermore, the lower ends of the connecting rods are movably sleeved with first springs, and the first springs are respectively located inside the rotating sleeves on the same side.

[0011] Furthermore, the vibration mechanism includes a single-tooth gear, a torsion spring, a rotating shaft and an arc rod. The rotating shaft is rotatably connected to the inside of the rotating holes symmetrically arranged in the front and rear of the fixing ring at the lower end. The lower end of the rotating shaft is provided with an arc rod in contact with the outer side surface of the placement tube, and the upper end of the rotating shaft is provided with a single-tooth gear matching the gear ring. The upper end of the rotating shaft is sleeved with a torsion spring, the inner end of the torsion spring is fixedly connected to the rotating shaft on the same side, and the outer end of the torsion spring is fixedly connected to the fixing ring at the lower end.

[0012] Furthermore, the strip-shaped openings evenly arranged on the outer side of the placing tube are slidably connected with force transmission plates, the outer side of the force transmission plate is provided with an arc plate, the arc plate is cooperated with the arc rod, and reset springs are evenly arranged at the gap between the inner arc surface of the arc plate and the outer side surface of the placing tube to ensure that when the placing tube vibrates, the vibration force can be transmitted to the syringe bottle.

[0014] Furthermore, a sealing cover is buckled at the upper opening of the placing tube, a second spring is provided on the inner top wall of the sealing cover, and a pressure plate is provided at the lower end of the second spring which is slidably connected to the inner wall of the sealing cover. The pressure plate contacts the upper end of the syringe bottle, thereby fixing the syringe bottle more firmly.

[0015] Furthermore, an elastic hook that cooperates with the sealing cover is symmetrically arranged on the upper edge of the placement tube, so that the sealing cover is fixed more firmly.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The high-frequency oscillator for freeze-dried powder injection vials disclosed in the present invention places the vial containing the freeze-dried powder injection inside the placing tube, and then fastens the sealing cover so that the elastic hook on the upper surface of the placing tube cooperates with the sealing cover to engage, and the second spring and the pressure plate inside the sealing cover apply downward elastic pressure to the vial, so that the vial is fixed more firmly.

[0018] 2. The high-frequency oscillator for freeze-dried powder injection vials disclosed in the present invention controls the high-frequency vibrator inside the connecting frame to work. Under the elastic force of the first spring sleeved at the lower end of the connecting rod, downward elastic pressure is applied to the connecting rod, so that the rubber plug at the lower end of the vial can be fitted with the vibration plate. The high-frequency vibrator works to perform high-frequency oscillation on the freeze-dried powder injection inside the vial. At this time, the vial contacts the vibration plate and the vibration plate rotates synchronously with the vial, which can avoid damage to the rubber plug of the vial. The high-frequency vibrator works to perform high-frequency oscillation on the freeze-dried powder injection inside the vial. While oscillating, the controller controls the motor to work, and drives the two driven gears to rotate synchronously through the driving gear, and then the two rotating sleeves drive the connecting rod and the transmission gear to rotate synchronously. Since the force transmission plate slidingly connected inside the placement tube is in contact with the vial, the vial rotates synchronously with the placement tube under the action of friction, so that the lyophilized powder needle inside the vial oscillates more evenly, and the lyophilized powder needle is in full contact with the rubber stopper at the lower end of the vial, which is convenient for inspecting whether there will be abnormal changes in the key quality indicators of the drug when the lyophilized powder needle is in contact with the rubber stopper for a long time.

[0019] 3. The high-frequency oscillator for freeze-dried powder injection vials disclosed in the present invention, when the gear ring rotates, when the gear ring meshes with the single-tooth gear on the upper end of the rotating shaft, the single-tooth gear is rotated by a certain angle, and at the same time, the rotating shaft and the arc-shaped rod are rotated outward by a certain angle, and the torsion spring undergoes elastic deformation to store energy, and when the gear ring is disengaged from the single-tooth gear, the rotating shaft and the arc-shaped rod are quickly reset under the elastic force of the torsion spring, and the arc-shaped rod contacts the arc-shaped plate corresponding to the outer side surface of the placement tube, and at the same time, the collision force is transmitted to the vial through the force transmission plate, and then the force transmission plate is reset under the elastic force of the reset spring, which assists the vibration of the vial, and the vibration of the vial is more comprehensive, thereby greatly improving the oscillation efficiency of the freeze-dried powder injection inside the vial.

The upper end of the convex shaft is rotatably connected with a vibration plate 91 through a plane bearing. The vibration plate 91 contacts the rubber plug at the lower end of the syringe bottle 5. The rotating mechanism 2 includes a fixing ring 21, a transmission gear 22, a gear ring 23 and a connecting rod 24.

The lower end of the connecting rod 24 is movably sleeved with a first spring 241, the first spring 241 is respectively located inside the rotating sleeve 7 on the same side. Under the elastic force of the first spring 241 sleeved on the lower end of the connecting rod 24, downward elastic pressure is applied to the connecting rod 24, the fixing ring 21 and the placing tube 4, so that the rubber plug at the lower end of the vial 5 can fit with the vibration plate 91 at the upper end of the high-frequency vibrator 9. The high-frequency vibrator 9 works to perform high-frequency oscillation on the freeze-dried powder injection inside the vial 5. When the vial 5 vibrates, the placing tube 4 vibrates vertically synchronously with the vial 5 to avoid the vial 5 vibrating alone and colliding with the placing tube 4. Since the placing tube 4 is placed in the upper end opening of the shell 1, the placing tube 4 can rotate while vibrating vertically. The upper end of the placing tube 4 is provided with a convex edge, which can limit the maximum descending position of the placing tube 4.The fixing ring 21 at the upper end can limit the maximum upward position of the placement tube 4. At the same time, the motor 10 works, and the driving gear 11 drives the two driven gears 71 to rotate synchronously, so that the two rotating sleeves 7 drive the connecting rod 24 and the transmission gear 22 to rotate synchronously, and the toothed ring 23 meshing with the transmission gear 22 drives the placement tube 4 to rotate, so that the vial 5 rotates synchronously with the placement tube 4. At this time, the vial 5 contacts the vibration plate 91 and the vibration plate 91 rotates synchronously with the vial 5, which can avoid damage to the rubber stopper of the vial 5, so that the freeze-dried powder injection inside the vial 5 can vibrate more evenly;

[0030] Vibration mechanism 3: symmetrically arranged at the front and rear ends of the rotating mechanism 2, the two vibration mechanisms 3 are in contact with the outer side of the placement tube 4, the vibration mechanism 3 includes a single-tooth gear 31, a torsion spring 32, a rotating shaft 33 and an arc-shaped rod 34, the rotating shaft 33 is respectively rotatably connected to the inside of the rotating hole symmetrically arranged in the front and rear of the fixing ring 21 at the lower end, the lower end of the rotating shaft 33 is provided with an arc-shaped rod 34 in contact with the outer side of the placement tube 4, and the upper end of the rotating shaft 33 is provided with a single-tooth gear 31 matched with the gear ring 23 The upper end of the rotating shaft 33 is sleeved with a torsion spring 32, the inner end of the torsion spring 32 is fixedly connected to the rotating shaft 33 on the same side, and the outer end of the torsion spring 32 is fixedly connected to the fixing ring 21 at the lower end. The strip-shaped openings uniformly arranged on the outer side of the placement tube 4 are slidably connected with a force transmission plate 43, and the outer side of the force transmission plate 43 is provided with an arc plate 41, which is matched with the arc rod 34, and the gap between the inner arc surface of the arc plate 41 and the outer side surface of the placement tube 4 is uniformly provided with The inner ends of the return spring 42 and the force transmission plate 43 are both located inside the placement tube 4. The inner ends of the force transmission plate 43 are both provided with round rods that contact the outer side of the cillin bottle 5. The diameter of the round rods is greater than the thickness of the force transmission plate 43, which can prevent the force transmission plate 43 from being pulled out. When the gear ring 23 rotates, when the gear ring 23 meshes with the single-tooth gear 31 at the upper end of the rotating shaft 33, the single-tooth gear 31 rotates a certain angle, and at the same time, the rotating shaft 33 and the arc rod 34 rotate outwards a certain angle, and the torsion spring 32 undergoes elastic deformation and stores energy. When the gear ring 23 is out of mesh with the single-tooth gear 31, the elastic force of the torsion spring 32 drives the rotating shaft 33 and the arc rod 34 to quickly reset. The arc rod 34 contacts the arc plate 41 corresponding to the outer side of the placement tube 4. At the same time, the collision force is transmitted to the vial 5 through the force transmission plate 43. Then, the force transmission plate 43 is reset under the elastic force of the reset spring 42, which assists the vial 5 in vibrating, thereby greatly improving the oscillation efficiency of the freeze-dried powder injection inside the vial 5.

The high-frequency vibrator 9 works to perform high-frequency oscillation on the freeze-dried powder injection inside the vial 5. At this time, the vial 5 contacts the vibration plate 91 and the vibration plate 91 rotates synchronously with the vial 5, which can avoid damage to the rubber stopper of the vial 5. While oscillating, the controller 17 controls the motor 10 to work, and drives the two driven gears 71 to rotate synchronously through the driving gear 11, thereby causing The two rotating sleeves 7 drive the connecting rod 24 and the transmission gear 22 to rotate synchronously, and drive the placement tube 4 to rotate through the toothed ring 23 meshing with the transmission gear 22. When the toothed ring 23 rotates, when the toothed ring 23 meshes with the single-tooth gear 31 on the upper end of the rotating shaft 33, the single-tooth gear 31 rotates a certain angle, and at the same time, the rotating shaft 33 and the arc rod 34 rotate outwards a certain angle, and the torsion spring 32 undergoes elastic deformation to store energy. When the toothed ring 23 is out of mesh with the single-tooth gear 31, the elastic force of the torsion spring 32 drives the rotating shaft 33 and the arc rod 34 is quickly reset, and the arc rod 34 contacts the arc plate 41 corresponding to the outer side surface of the placement tube 4, and at the same time transmits the collision force to the syringe bottle 5 through the force transmission plate 43, and then the force transmission plate 43 is reset under the elastic force of the reset spring 42, which assists the syringe bottle 5 to vibrate, greatly improving the oscillation efficiency of the freeze-dried powder injection inside the syringe bottle 5, and making the freeze-dried powder injection fully contact with the rubber stopper at the lower end of the syringe bottle 5, which is convenient for inspecting whether there will be abnormal changes in the key quality indicators of the drug when the freeze-dried powder injection is in contact with the rubber stopper for a long time.
