Description

Technical Field

[0001] This utility model relates to an automatic shaker for mixed insulin, belonging to the field of medical device technology. Background Technology

[0002] Insulin is a key drug for diabetic patients to control blood sugar. Mixed insulin (such as premixed insulin) must be shaken thoroughly before injection to ensure that the liquid in the bottle is evenly suspended, thereby ensuring the accuracy of each injection dose. If it is not shaken thoroughly, it will lead to uneven insulin concentration, which will cause blood sugar fluctuations and pose a serious risk to the patient's health.

[0003] Currently, the mixing of mixed insulin mainly relies on manual operation. The common method is for the patient or medical staff to roll the insulin pen back and forth horizontally between their hands, combined with several up-and-down movements. This manual mixing method has many drawbacks: First, the force, frequency, and duration of mixing are difficult to standardize, and the operation varies greatly among different individuals, which can easily lead to inconsistent mixing results. Second, for elderly patients with arthritis, hand weakness, or poor vision, manual mixing is strenuous and difficult, making it difficult to ensure sufficient mixing. Third, manual operation takes a certain amount of time and depends on the user's compliance. When busy or negligent, insufficient mixing may affect the efficacy. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic shaker for mixed insulin.

[0005] The technical solution adopted by this utility model to solve its technical problem is: An automatic shaker for mixed insulin includes a power supply control device, a human-machine interface device is fitted into one side of the power supply control device, a partition ring is provided on the upper side of the power supply control device, a support plate is provided on the upper side of the partition ring, a soft rubber protective ring is provided on the upper side of the support plate, a mounting base is rotatably connected to the upper side of the soft rubber protective ring, a plurality of insulin placement slots are provided on the upper side of the mounting base, and a shaking drive assembly is provided on the lower side of the mounting base. The shaking drive assembly is used to rotate and vibrate the mixed insulin in the insulin placement slots to mix it.

[0006] Through the above technical solution, the soft rubber protective ring limits the rotation range of the mounting base to prevent it from shifting. The insulin placement slot is used to hold the mixed insulin container. Under the control of the power supply control device, the shaking drive component drives the mounting base to make specific movements, thereby making the mixed insulin in the insulin placement slot rotate and vibrate to ensure that the components of insulin are evenly mixed. This realizes the automated operation of shaking mixed insulin, replacing manual shaking, avoiding the problem of uneven mixing caused by inconsistent shaking force and frequency, and improving the accuracy of insulin mixing.

[0007] Preferably, the shaking drive assembly includes a through hole and a limiting member. The through hole is located in the middle of the mounting base, and a guide groove is provided inside the through hole. The limiting member is located on the upper side of the through hole, and a guide slider is provided inside the guide groove. A connecting rod is provided on one side of the guide slider. A motor is provided on the lower side of the mounting base, and the output end of the motor is connected to the bottom end of the connecting rod. Several support rods are provided on the lower side of the mounting base, and ball bearings are rotatably connected to the lower side of the support rods. The outer side of the ball bearings abuts against the upper side of the support plate. Several inclined plates are provided on the upper side of the support plate. A washer is provided at the top of the connecting rod, and a spring is provided on the lower side of the washer. An elastic sleeve is provided on the outer side of the spring.

[0008] Through the above technical solution, the motor starts under the command of the power supply control device, and its output end drives the connecting rod to rotate around its own axis; the guide slider at the top of the connecting rod is embedded in the guide groove of the through hole in the middle of the mounting base. When the connecting rod rotates, the mounting base rotates synchronously through the cooperation of the guide slider and the guide groove; the bottom end of the support rod on the lower side of the mounting base is connected to a ball bearing, which contacts the upper side of the support plate. During the rotation of the mounting base, the ball bearing rolls along the inclined plate on the support plate. Due to the height difference of the inclined plate, the mounting base vibrates up and down while rotating; the cooperation between the ball bearing and the inclined plate enables the mounting base to vibrate without additional power, simplifying the structure and reducing energy consumption. The shim plays a stabilizing role for the spring. The spring and elastic sleeve are fitted on the outside of the connecting rod to provide cushioning when the mounting base vibrates up and down, avoiding component wear caused by hard contact. The cushioning effect of the spring and elastic sleeve reduces equipment operating noise and wear between components, extending the service life of the equipment. The limiting component is fixed on the upper side of the through hole to prevent the guide slider from disengaging from the guide groove, ensuring the stability of the drive component operation. The limiting component ensures the stability of the guide slider's movement trajectory, avoiding equipment failure caused by component disengagement, and improving the reliability of equipment operation. Combining the two motion forms of rotation and vibration, compared with single rotation or vibration, it can mix mixed insulin more quickly and thoroughly, shorten the shaking time, and improve mixing efficiency.

[0009] Preferably, a fixing block is provided in the insulin placement slot, an adjusting rod is threaded through one side of the insulin placement slot, a knob is provided at the end of the adjusting rod away from the fixing block, and a fastening block is provided at the end of the adjusting rod close to the fixing block. Both the fastening block and the fixing block are arc-shaped.

[0010] With the above technical solution, the fixing block in the insulin placement slot has an arc-shaped structure that fits the outer wall of the insulin container and plays an initial positioning role. The user rotates the knob to move the adjusting rod along the threaded hole of the insulin placement slot. The end of the adjusting rod near the fixing block is connected to the arc-shaped fastening block. As the adjusting rod is pushed forward, the fastening block moves towards the fixing block and works with the fixing block to clamp the insulin container, thus fixing the container in the placement slot. After the container is fixed, it will not shift or shake during the mixing process, ensuring the stability of the insulin mixing process and avoiding leakage of the drug solution caused by the container tipping over.

[0011] Preferably, the upper side of the connecting rod is provided with a threaded groove, a threaded rod is threadedly connected in the threaded groove, a pressure plate is provided at the top of the threaded rod, a rubber plate is provided at the lower side of the pressure plate, and a protrusion is provided at the upper side of the pressure plate.

[0012] Through the above technical solution, a threaded groove is opened on the upper side of the connecting rod, and the threaded rod is threadedly connected to the threaded groove. The user drives the threaded rod to rotate by rotating the protrusion, so that the threaded rod moves up and down along the threaded groove. The top of the threaded rod is connected to the pressure plate, and the rubber plate on the lower side of the pressure plate contacts the top of the insulin container. When the threaded rod descends, the pressure plate drives the rubber plate to press down, fixing the top of the insulin container. Together with the fixing structure in the groove, the container is fixed in both directions. The two-way fixing method further improves the stability of the insulin container, especially during equipment vibration, to prevent the container from moving up and down and to ensure safety during the shaking process.

[0013] Preferably, two rubber vacuum suction cups are arranged in parallel and symmetrically on the lower side of the power supply control device.

[0014] With the above technical solution, when in use, pressing the shaker expels the air between the suction cup and the flat surface such as the table, creating a vacuum environment inside the suction cup. Atmospheric pressure then firmly adheres the suction cup to the flat surface, thus fixing the entire shaker in place. This vacuum adsorption fixing method effectively prevents the shaker from shifting or sliding during operation, ensuring the stability of the equipment and avoiding the tipping of insulin containers or interruption of mixing due to equipment sliding.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a power supply control device to drive a shaking component, enabling automatic rotation and vibration mixing of mixed insulin. This completely replaces manual shaking, avoiding uneven insulin mixing caused by inconsistent force, frequency, and duration during manual operation. It ensures uniform distribution of all effective components of insulin and guarantees accurate dosage. Compared to manual shaking, automated operation can significantly shorten the shaking time and improve the efficiency of insulin preparation in clinical or home use.

[0016] This invention uses a motor to drive a connecting rod to rotate, and the guide slider and guide groove work together to drive the mounting base to rotate synchronously. At the same time, the ball bearings roll along the inclined plate of the support plate. The height difference of the inclined plate causes the mounting base to vibrate up and down, forming a compound shaking motion of rotation and vibration. Compared with a single rotation or single vibration shaking method, this compound motion can break the layered structure inside the insulin liquid, accelerate the fusion of components, and is especially suitable for high-concentration mixed insulin that is prone to layering, significantly improving the thoroughness of shaking.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 This utility model provides a technical solution: An automatic shaker for mixed insulin includes a power supply control device 1, a human-machine interface device 2, a spacer ring 3, a support plate 4, a soft rubber protective ring 5, a mounting base 6, and a shaking drive assembly.

[0022] The power supply control device 1 is equipped with a battery and a control circuit board. The human-machine interface device 2 is embedded in the front panel of the power supply control device 1. It may include, but is not limited to, a power switch, a mode selection button, a timer setting button, and an LCD screen, which are used by the user to set the shaking parameters and display the working status.

[0023] The upper surface of the power supply control device 1 is connected to a spacer ring 3 by a snap fastener. The spacer ring 3 is preferably made of a flexible material such as rubber or silicone, and is used for shock absorption and sealing.

[0024] A support plate 4 is fixedly installed on the upper side of the spacer ring 3. The support plate 4 is preferably a circular metal or high-strength engineering plastic plate. A soft rubber protective ring 5 is fixedly installed on the upper surface edge of the support plate 4. The soft rubber protective ring 5 is made of soft material such as silicone and is used to cushion the rocking process.

[0025] The mounting base 6 is supported above the support plate 4 by the shaking drive assembly at its lower part, and can perform complex movements relative to the support plate 4. The upper surface of the mounting base 6 is evenly provided with a number of insulin placement slots 7 along its circumference. The shape of the placement slots 7 is adapted to the medicine bottle part of the insulin pen and is used to hold the insulin pen to be shaken.

[0026] The shaking drive assembly is used to drive the mounting base 6 and the insulin placement slot 7 thereon to perform a combination of rotation and vibration to achieve thorough mixing of the mixed insulin.

[0027] The shaking drive assembly includes: a through hole, a limiting member 8, a guide slider 9, a connecting rod 10, a motor 11, a support rod 12, a ball bearing 13, an inclined plate 14, a spring 15, and an elastic sleeve 16.

[0028] The motor 11 is fixedly installed at the center of the lower side of the mounting base 6.

[0029] The bottom end of the connecting rod 10 is fixedly connected to the output shaft of the motor 11, so that the motor 11 can drive the connecting rod 10 to rotate.

[0030] A through hole is provided in the middle of the mounting base 6. A guide groove is provided on the inner wall of the through hole. A limiting member 8 is provided at the upper end of the through hole to prevent internal parts from falling out.

[0031] The guide slider 9 is sleeved on the connecting rod 10 and slides in cooperation with the guide groove. When the connecting rod 10 rotates, the guide slider 9 is constrained by the guide groove, which converts the rotational motion of the connecting rod 10 into the undulating motion of the mounting base 6 on a specific trajectory.

[0032] Several support rods 12 are evenly distributed around the motor 11 on the lower side of the mounting base 6. The bottom end of each support rod 12 is rotatably connected to a ball bearing 13 via a ball hinge. All the balls bearing 13 are in contact with the upper surface of the support plate 4.

[0033] The upper surface of the support plate 4 corresponds to the movement trajectory of the ball 13 and is fixedly provided with several inclined plates 14. When the mounting base 6 is driven to rotate, the ball 13 rolls on the inclined plates 14, and the undulating contour of the inclined plates 14 will further force the mounting base 6 to vibrate up and down.

[0034] The top of the connecting rod 10 is fitted with a washer 17, a spring 15 and an elastic sleeve 16 in sequence. The upper end of the spring 15 presses against the limiting member 8 or the inner wall of the through hole, and the lower end is pressed against the guide slider 9 through the washer 17, providing continuous downward pressure to the mounting seat 6, ensuring that the ball 13 is always in close contact with the inclined plate 14, while also playing a role in buffering and energy storage, and enhancing the vibration effect. The elastic sleeve 16 is wrapped around the outside of the spring 15 to prevent dust and prevent the spring from jamming.

[0035] In this embodiment, during operation, the user starts the device through the human-computer interaction device 2. The motor 11 drives the connecting rod 10 to rotate. The connecting rod 10, through the cooperation of the guide slider 9 and the guide groove, drives the entire mounting base 6 to rotate. The ball bearings 13 at the bottom of the mounting base 6 roll on the inclined plate 14 of the support plate 4. Due to the change in height of the inclined plate 14, the rotating mounting base 6 simultaneously generates regular up-and-down vibrations. This composite motion of rotation and vibration can efficiently and quickly shake the suspension in the insulin pen.

[0036] An arc-shaped fixing block 18 is fixedly installed on one side of the inner wall of the insulin placement slot 7. On the other side of the placement slot 7, an adjusting rod 19 is threaded through the side wall of the mounting base 6. A knob 20 for easy turning is fixedly installed at the outer end of the adjusting rod 19, and an arc-shaped fastening block 21 is fixedly connected to its inner end through a bearing or directly.

[0037] In this embodiment, by turning the knob 20, the fastening block 21 can be driven to move toward or away from the fixing block 18, thereby clamping or loosening the insulin pen placed between the fixing block 18 and the fastening block 21. The opposing surfaces of the fixing block 18 and the fastening block 21 are preferably adhered with rubber or silicone pads to increase friction and prevent scratching the insulin pen.

[0038] The top of the connecting rod 10 has a threaded groove, and the lower end of the threaded rod 22 is threadedly connected to the threaded groove. A circular pressure plate 23 is fixedly connected to the top of the threaded rod 22. A layer of rubber plate 24 is adhered to the lower surface of the pressure plate 23 to increase friction with the tail of the insulin pen and to provide protection.

[0039] In this embodiment, the height of the pressure plate 23 can be adjusted by rotating the threaded rod 22. After inserting an insulin pen, unscrew the pressure plate 23 so that the rubber plate 24 presses firmly against the tail end face of all insulin pens, thus reliably fixing them in place. The upper surface of the pressure plate 23 may also be provided with protrusions 25 to facilitate the user's application of force for rotation.

[0040] Two rubber vacuum suction cups 26 are installed symmetrically at the bottom of the power supply control device 1. By pressing the power supply control device 1, the vacuum suction cups 26 can expel air and firmly adhere to the table surface.

[0041] 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.
