Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically a drug horizontal oscillator. Background Technology

[0002] Currently, many drugs prepared for static compounding require agitation to dissolve. Static compounding typically requires preparation under a biosafety cabinet or laminar flow hood. Therefore, the shaker can usually only handle a limited number of drugs simultaneously, and the vibrations are significant, making it difficult to prepare other drugs on the workbench while agitating. Long-term drug preparation experience has shown that most drugs can dissolve after a period of time with solvent added and allowed to stand. A few exceptions, such as piperacillin-tazobactam, can also dissolve after slight tapping to disperse the drug at the bottom and allowing it to stand. This design addresses the problems of long standing times, limited dissolution volumes, and workbench vibrations that prevent the preparation of other drugs. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a drug level oscillator.

[0004] The present invention adopts the following technical solution:

[0005] A drug horizontal shaker includes a shaking platform, a support, a placement tray, and a shaking mechanism. The shaking platform is arranged horizontally. The support is laterally movable on the shaking platform. Several placement trays are stacked on the support and move together. The shaking mechanism, located in the shaking platform, drives the support to move back and forth horizontally. It includes a baffle, a roller, a drive motor, and a return spring. The baffle is formed at the bottom of the support and extends into the shaking platform. The roller is rotatably disposed in the shaking platform and has a protrusion extending to one side. The protrusion contacts the baffle as the roller rotates and pushes it to the left. The drive motor is connected to a cam and drives it to rotate. The return spring is connected between the bottom of the support and the right side of the shaking platform to ensure that the support always has a tendency to move to the right.

[0006] Preferably, the oscillation platform is provided with a sliding groove along the horizontal direction, the support is movably disposed in the sliding groove, the bottom of the sliding groove is recessed and formed with a groove, and the oscillation mechanism is disposed in the groove.

[0007] Preferably, the oscillation mechanism further includes a limiting plate disposed on the bottom surface of the support located on the right side of the baffle, and a limiting block formed on the inner walls of the front and rear sides of the groove that can contact the limiting plate to limit the movement range of the support.

[0008] Preferably, a first connecting rod is provided on the right side of the limiting plate, and a second connecting rod opposite to the first connecting rod is formed on the inner wall of the right side of the groove, and the return spring is connected between the first connecting rod and the second connecting rod.

[0009] Preferably, the bracket has several pairs of uprights on its front and rear sides, and each pair of uprights has an inwardly recessed mounting groove extending in the vertical direction on its opposite surface. The placement tray has mounting blocks on both sides, which can be embedded in the mounting groove and supported on the bracket or the placement tray below.

[0010] Preferably, the top surface of the placement tray is recessed downwards and has several placement slots for placing the medicine to be shaken, and the length of the mounting block is greater than the height of the medicine at the highest point in the placement slot.

[0011] Preferably, a plurality of reset springs are provided, and the number of reset springs increases with the number of brackets.

[0012] Preferably, the length and width of the groove are both smaller than the length and width of the slide.

[0013] As can be seen from the above description of this utility model, compared with the prior art, the beneficial effects of this utility model are: the rotating wheel drives the protrusion to rotate, and the protrusion intermittently contacts the baffle at the bottom of the support and pushes it to one side when rotating. When the protrusion separates from the baffle, the return spring pulls the support to reset, realizing the reciprocating motion of the support to oscillate and place the medicine in the tray. No control module is required, and it can be completed by controlling the start and stop of the motor. The structure is simple and easy to maintain, and the oscillation amplitude is very small, which can effectively avoid interfering with other operations on the dispensing table during oscillation. It has high practicality. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below through specific embodiments.

[0021] Reference Figures 1 to 5 As shown, a drug horizontal oscillator includes an oscillation platform 1, a support 2, a placement tray 3, and an oscillation mechanism 4.

[0022] The oscillation platform 1 is arranged horizontally, and a slide 11 is provided on the oscillation platform 1 along the horizontal direction. The bottom of the slide 11 is recessed to form a groove 12. The length and width of the groove 12 are smaller than the length and width of the slide 11, which facilitates the installation of the device on it.

[0023] The bracket 2 is movably mounted on the slide groove 11. Several pairs of uprights 21 are provided on the front and rear sides of the bracket 2, and each pair of uprights 21 has an inwardly recessed mounting groove 22 extending in the vertical direction on the opposite surface.

[0024] The placement trays 3 are composed of several units, which can be stacked on the support 2 and moved together. Mounting blocks 31 are provided on both sides of the placement trays 3. The mounting blocks 31 can be embedded in the mounting grooves 22 and supported on the support 2 or the lower placement tray 3. Specifically, the top surface of the placement tray 3 is recessed to form several placement grooves 32 for placing the medicine to be shaken. The length of the mounting blocks 31 is greater than the height of the medicine at its highest point in the placement grooves 32, to prevent the bottom surface of the upper placement tray 3 from contacting the medicine in the lower placement tray 3.

[0025] The oscillation mechanism 4 is set in the groove 12 of the oscillation platform 1 to drive the support 2 to move back and forth in the horizontal direction. It includes a baffle 41, a rotating wheel 42, a drive motor 43, and a return spring 44. The baffle 41 is formed at the bottom of the support 2 and extends into the oscillation platform 1. The rotating wheel 42 is rotatably set in the oscillation platform 1 and has a protrusion 45 protruding to one side. The protrusion 45 can rotate with the rotating wheel 42 to contact the baffle 41 and push it to the left. The drive motor 43 is connected to the cam and drives it to rotate. The return spring 44 is connected between the bottom of the support 2 and the right side of the oscillation platform 1 to drive the support 2 to always have a tendency to move to the right. There are several return springs 44, and the number of return springs 44 increases with the number of supports 2 to ensure the return speed of the support 2 and avoid the support 2 from being too heavy due to too much medicine on it, which would reduce the return speed of the support 2 and avoid affecting the cooperation between the protrusion 45 and the baffle 41. Specifically, it also includes a limiting plate 48 located on the bottom surface of the bracket 2 to the right of the baffle 41, and a limiting block 49 formed on the inner walls of the front and rear sides of the groove 12, which can contact the limiting plate 48 to limit the movement range of the bracket 2. Furthermore, a first connecting rod 46 is provided on the right side of the limiting plate 48, and a second connecting rod 47 opposite to the first connecting rod 46 is formed on the inner wall of the right side of the groove 12. A return spring 44 is connected between the first connecting rod 46 and the second connecting rod 47.

[0026] In use, select the corresponding number of placement trays 3 according to the quantity of medicine to be shaken. Place the medicine to be shaken into the placement trays 3 and then place them sequentially on the support 2. Connect the corresponding number of return springs 44 between the first link 46 and the second link 47 according to the number of placement trays 3. Start the device; the motor drives the rotating wheel 42 to rotate. The protrusion 45 rotates and contacts the baffle 41, pushing it forward. At this time, the support 2 begins to move to the left. When the protrusion 45 separates from the baffle 41, the support 2 quickly returns to its original position under the action of the return springs 44, completing one shake of the medicine on the placement trays 3. Repeat the above steps until the medicine shake is complete. This application requires no control module; only the start and stop of the motor need to be controlled. The structure is simple and easy to maintain, and the oscillation amplitude is very small, effectively avoiding interference with other operations on the dispensing table during oscillation, making it highly practical.

[0027] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model should still fall within the scope of the patent of the present utility model.
