Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a device for preparing and mixing injectable drugs. Background Technology

[0002] Injectable drugs refer to sterile solutions prepared for injection into the body, as well as sterile powders or concentrated solutions prepared into solutions or suspensions before use. Injectable drugs have a rapid and reliable effect, are not affected by pH, enzymes, or food, have no first-pass effect, and can exert systemic or localized effects. They are suitable for patients who cannot take oral medications or are unable to take oral medications. However, the research and production process of injectable drugs is complex, their safety and adaptability to the body are poor, and their cost is high. When preparing some injectable drugs, it is necessary to shake the solution to be prepared.

[0003] However, existing methods for preparing and mixing injectable drugs usually rely on manual shaking, which results in poor uniformity and cannot mix multiple drugs in batches. This requires repeated shaking, which can cause arm pain and heavy workload for medical staff. Therefore, we propose an injectable drug preparation and mixing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for preparing and mixing injectable drugs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mixing device for preparing injectable drugs, comprising a base, a cylinder above the base, a circular plate inside the cylinder, the circular plate being able to slide up and down inside the cylinder, a driving mechanism for driving the circular plate to slide up and down below the circular plate, and multiple clamping mechanisms for batch fixing of medicine bottles above the circular plate.

[0006] More preferably, the drive mechanism includes a second motor, which is fixedly connected to the outside of the cylinder. The output shaft of the second motor is rotatably connected to the cylinder and extends into the cylinder, where a reciprocating lead screw is fixedly connected. The other end of the reciprocating lead screw is rotatably connected to the inner wall of the cylinder. A rectangular block is fitted to the outside of the reciprocating lead screw. A connecting rod is rotatably connected to the top of the rectangular block via a hinge. The top end of the connecting rod is rotatably connected to the bottom of the circular plate via a hinge.

[0007] More preferably, a slide rail is fixedly connected to the bottom inner wall of the cylinder, and a slider is fixedly connected to the bottom of the rectangular block, with the slider slidably connected to the slide rail.

[0008] More preferably, a second round rod is fixedly connected to the inner wall of the bottom of the cylinder, a first round rod is slidably connected to the outer side of the second round rod, the top end of the first round rod is fixedly connected to the bottom of the circular plate, a first spring is fixedly connected between the first round rod and the cylinder, and the first spring is movably sleeved on the outer side of the second round rod.

[0009] More preferably, the base is hollow, and a rotating shaft is fixedly connected to the bottom of the cylinder. The rotating shaft extends into the base and is rotatably connected to the base through a bearing. A driven gear is fixedly connected to the bottom end of the rotating shaft. A first motor is fixedly connected to the bottom inner wall of the base. A driving gear is fixedly connected to the end of the output shaft of the first motor. The driving gear meshes with the driven gear.

[0010] More preferably, the clamping mechanism includes a fixed plate and a clamping block. The top of the clamping block has an arc-shaped groove, and the top of the arc-shaped groove has a bevel. Two square rods are fixedly connected to the two fixed plates on their adjacent sides. The clamping block is slidably sleeved on the outside of the square rods. A second spring is fixedly connected between the clamping block and the fixed plate.

[0011] More preferably, the top of the base is provided with a timing controller and a timing display screen, and the timing controller and timing display screen control the timing through a built-in timing sensor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this utility model, the medicine bottle is placed above the bevel and pressed down. The two clamping blocks open to both sides and slide on the outside of the square rod. The second spring is compressed, and the medicine bottle is clamped under the reaction force of the second spring. The timing sensor is controlled by rotating the timing controller to set the time. The timing display shows the timing time. The timing sensor controls the start of the first motor and the second motor. The first motor drives the drive gear to rotate. The drive gear drives the rotating shaft to rotate through the driven gear. The rotating shaft drives the cylinder to rotate, thereby rotating the medicine bottle to shake it evenly. The second motor drives the reciprocating screw to rotate. The reciprocating screw drives the rectangular block to move back and forth laterally on its outside. This pulls the circular plate up and down through the connecting rod, thereby shaking the medicine bottle up and down evenly. This allows the medicine bottle to be fully shaken. At the same time, it can be operated in batches, saving time and effort and has high practicality. Attached Figure Description
