Description

Technical Field

[0001] This utility model relates to the field of laboratory reagent storage technology, and in particular to a medical laboratory reagent storage device. Background Technology

[0002] Medical testing reagents are preparations used in medical treatment to scientifically quantify or qualitatively detect physiological or pathological phenomena in patients. Doctors diagnose patients based on the test results and provide further accurate treatment accordingly. With the advancement of medicine and the continuous improvement of medical quality, the market demand for testing reagents is expanding. Through continuous development efforts, many new testing technologies, reagents, and equipment have emerged to meet market demands.

[0003] Existing medical testing reagent storage devices typically consist of a compartment and a reagent tray housed within it. The tray holds reagent bottles, while the compartment isolates the reagents from the external environment to maintain a suitable internal environment. However, due to the size limitations of the reagent tray, the storage capacity is relatively small, and the retrieval of reagents still requires manual operation, resulting in a low level of automation. Utility Model Content

[0004] This invention addresses the problems of the prior art by providing a medical testing reagent storage device. The device increases the capacity of the testing reagents through the design of multiple rows of ring-shaped storage units, and achieves automated operation of the testing reagents through the design of a rotating structure and a gripping mechanism.

[0005] Therefore, the technical solution of this utility model is a medical testing reagent storage device, which includes a base, an outer cylinder, an inner storage cylinder, a rotating support assembly, and a gripping mechanism. The outer cylinder is installed above the base, the inner storage cylinder and the rotating support assembly are installed inside the outer cylinder, and the gripping mechanism is installed on the outside of the base and the outer cylinder. The upper and lower ends of the rotating support assembly are fixedly connected to the outer cylinder and the base, respectively. The inner storage cylinder is rotatably connected to the outer cylinder and the base through the rotating support assembly. The inner storage cylinder includes a storage body, an upper cylinder plate, and a lower cylinder plate. The storage body is provided with multiple rows of annularly distributed storage units. The gripping mechanism includes an upper fixed plate and a lower fixed plate. A lifting support plate is provided between the upper fixed plate and the lower fixed plate. A lifting slide rail is provided in the middle of the lifting support plate. A lifting assembly is installed on the lifting slide rail, and a gripping assembly is installed on the lifting assembly.

[0006] Furthermore, a rotary motor is installed on the upper surface of the base, and an annular drive wheel is provided on the outer side of the rotary drive gear of the rotary motor. The annular drive wheel is fixedly connected to the storage inner cylinder.

[0007] Furthermore, a rotational position sensor is provided on the upper surface of the base, and a maintenance door is provided on the side of the base.

[0008] Furthermore, the bottom of the inner chamber of the storage unit is tilted downwards at an angle of 25-30 degrees.

[0009] Furthermore, the rotating support assembly includes a support column, the lower end of which is fixedly connected to the base via a lower support plate. A lower bearing seat is provided above the lower support plate and is fixedly connected to the lower cylinder plate. An upper bearing seat is provided at the upper end of the support column and is fixedly connected to the upper cylinder plate.

[0010] Furthermore, a rotating frame is provided in the middle of the support column. The rotating frame is rotatably connected to the support column through bearings. Multiple vertical plates are provided on the outer ring side of the rotating frame, and the vertical plates are fixedly connected to the storage cylinder.

[0011] Furthermore, the upper and lower ends of the lifting slide rail are respectively equipped with upper limit posts and lower limit posts.

A gripping cylinder is mounted on one end of the translational sliding frame, and a gripper is mounted on the gripping cylinder.

[0015] The beneficial effect of this utility model is that the storage cylinder is provided with multiple rows of annularly distributed storage units, which are used to hold test reagents. The storage units are arranged in annularly along the outer ring surface of the storage cylinder. The number of storage units in each group of annularly distributed storage units is several or dozens, and the number of rows of storage units is several or dozens.

[0040] The lifting assembly 54 includes a lifting slide 5401, which is slidably connected to the lifting slide rail 5301 via a slider.

[0041] The gripping assembly 55 includes a turntable 5501, which is connected to the output end of a steering motor 5404. A translational electric cylinder 5502 is fixedly mounted on the turntable 5501. A translational sliding frame 5503 is connected to the output end of the translational electric cylinder 5502.

A gripping cylinder 5505 is mounted at one end of the translational sliding frame 5503. Two grippers 5506 are mounted on the gripping cylinder 5505.

[0042] The working principle of this medical reagent storage device is as follows: When grasping a reagent, the sliding door of the outer chamber 2 is first opened. The rotary motor 12 drives the inner storage chamber 3 to rotate via the annular drive wheel 13. After being positioned by the rotation position sensor 14, the position where the reagent needs to be grasped is determined. The lifting motor 5402 drives the lifting slide 5401 to adjust its vertical position via the rack 5306. The steering motor 5404 drives the grasping assembly 55 to rotate and adjust the grasping position of the gripper 5506. The translation cylinder 5502 pushes the gripper 5506 closer to the reagent via the translation sliding frame 5503. The grasping cylinder 5505 drives the gripper 5506 to clamp the reagent, and the translation cylinder 5502 retracts to remove the reagent. Similarly, this device can also store reagents with the assistance of a feeding robotic arm.

[0043] The rotation position sensor 14, the upward lifting position sensor 5304, and the downward lifting position sensor 5305 of the present invention are specifically horseshoe-shaped photoelectric sensors. Their working principle is as follows: The horseshoe-shaped photoelectric sensor consists of two parts: a transmitter and a receiver. The transmitter emits a visible light or infrared light beam. When there is no object blocking the transmitter and the receiver, the light beam emitted by the transmitter reaches the receiver. When there is an object blocking the transmitter and the receiver, the light beam emitted by the transmitter cannot reach the receiver. By measuring the change in light intensity in the receiver, it can be determined whether there is an object blocking the light, and thus determine whether the detected object has passed through or reached the position of the sensor.

[0044] The rotation position sensor 14 of the present invention is used for positioning the rotational position of the inner storage cylinder 3. Specifically, when the inner storage cylinder 3 rotates, the rotation baffle 3301 on the lower cylinder plate 33 rotates with the inner storage cylinder 3. When the rotation baffle 3301 reaches the rotation position sensor 14, the rotation baffle 3301 blocks the transmitter and receiver of the rotation position sensor 14, and the inner storage cylinder 3 stops rotating. At this time, the first column of storage units 3101 of the inner storage cylinder 3 facing the gripping mechanism 5 is the first column. Starting from this column, the second column, the third column, the fourth column, and so on are sequentially arranged along the rotation direction of the inner storage cylinder 3. The inner storage cylinder 3 is arranged from top to bottom as the first row, the second row, the third row, the fourth row, and so on. That is, the rotational position of the inner storage cylinder 3 is initially positioned by the rotation position sensor 14, and then the reagents in the storage units 3101 of the Nth column and the Mth row can be gripped as needed.

[0045] After determining the position of the reagent to be grasped by the rotation position sensor 14, the grasping mechanism 5 is controlled by the control board to grasp the reagent in a coordinated manner. For example, if the reagent in the storage unit 3101 of the Nth column and Mth row needs to be grasped, firstly, the inner storage cylinder 3 starts to rotate. The rotating baffle 3301 on the lower cylinder plate 33 rotates with the inner storage cylinder 3. When the rotating baffle 3301 reaches the rotation position sensor 14, the rotating baffle 3301 blocks the transmitter and receiver of the rotation position sensor 14, and the inner storage cylinder 3 stops rotating. At this time, the column of storage units 3101 in the inner storage cylinder 3 directly opposite the grasping mechanism 5 is the first column, and this column is used as the starting point. The inner storage cylinder 3 is then rotated by a specific angle (e.g., 12*(N-1) degrees, which corresponds to the 30 columns of storage units 3101 on the inner storage cylinder 3), reaching the Nth column storage unit 3101. The lifting motor 5402 drives the lifting slide 5401 through the rack 5306 to adjust its vertical position, reaching the Mth row storage unit 3101 in the vertical direction. This enables the linkage of the lifting motor of the gripping mechanism 5, thereby enabling the gripping of reagents in the Nth column and Mth row storage units 3101.

[0046] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
