Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a blood collection tube grabbing and labeling device. Background Art

[0002] Blood collection and testing are common operations in medical and health settings. Blood samples are typically stored in vacuum blood collection tubes. This involves collecting blood into vacuum blood collection tubes, which are then post-processed according to specific requirements. For example, the vacuum blood collection tubes are placed in a centrifuge tube rack for blood separation.

[0003] In the actual operation process, in order to ensure that each patient's vacuum blood collection tube will not be confused with others, it is necessary to print the relevant information of each patient on a label paper, and then stick the label paper on the patient's corresponding vacuum blood collection tube, so as to facilitate the subsequent blood collection and testing procedures. The traditional labeling method is manual labeling by the operator, that is, the medical staff scans the patient's relevant information, uses a printer to print out a label containing the patient's information, and then the medical staff selects the corresponding vacuum blood collection tube and manually sticks the label on the test tube. Due to the large number of patients and the large number of types of vacuum blood collection tubes, the workload of medical staff is relatively large. In addition, manual labeling operations are prone to errors, which in turn cause medical accidents. In order to solve the above problems, researchers have developed a labeling machine to improve blood collection efficiency and reduce the workload of medical staff.

[0004] However, when using a traditional labeling machine for labeling operations, medical staff are often required to fill the vacuum blood collection tubes of specified colors and types into the corresponding test tube bins of the labeling machine in advance as required. The operation process is cumbersome. In addition, filling errors may occur, that is, the test tube bins and vacuum blood collection tube types do not match, which may cause blood collection failure or even medical accidents. To solve the above problems, a blood collection tube grabbing and labeling device can be designed using the principle of visual recognition and positioning and applied to the blood collection labeling process. The above-mentioned visual recognition and positioning technology is an existing technology and is widely used in various industries. For example, China Patent Publication No. CN118872487A discloses an autonomous picking platform and a picking method based on visual perception drive. Its working principle is to connect a positioning camera and a main control computer to obtain the location information of fruits and vegetables and then pick them. During the picking process, a picking image camera is connected to the main control computer to facilitate real-time monitoring of the picking process and operation results. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art by providing a device for grabbing and labeling blood collection tubes with a rational structural design. The device eliminates the need to fill blood collection tubes with specified colors and types as required. Instead, the entire tray of blood collection tubes can be placed on a tray and pushed into the workstation, significantly reducing operational difficulty and effectively preventing the use of incorrect blood collection tubes.

[0006] The utility model adopts the following technical solutions to solve the technical problems existing in the known technology: a blood collection tube grabbing and labeling device includes a mounting base, a mounting bracket is fixedly connected to the mounting base; a tray positioning structure is installed on the mounting base, and a plurality of tray pushing stations for inserting test tube trays are provided on the tray positioning structure, and the plurality of tray pushing stations are evenly distributed along the X direction; it also includes a printing and labeling assembly arranged beside the tray positioning structure, for printing labels and sticking labels on vacuum blood collection tubes; an X-axis traverse seat is installed on the mounting bracket, and also includes an X-axis driving assembly for driving the X-axis traverse seat to move along the X direction; a Y-axis traverse seat is installed on the X-axis traverse seat, and also includes a Y-axis driving assembly for driving the Y-axis traverse seat to move along the Y direction; a test tube clamp for grabbing the vacuum blood collection tube is installed on the Y-axis traverse seat, and also includes a lifting driving assembly for driving the test tube clamp to lift and move; it also includes a first camera installed on the Y-axis traverse seat and located beside the test tube clamp.

[0007] The advantages and positive effects of the present invention are as follows: the present invention provides a blood collection tube grabbing and labeling device, which can facilitate the staff to push in a test tube tray with a plurality of vacuum blood collection tubes by setting a tray positioning structure with multiple groups of trays pushing into the workstation, thus simplifying the loading operation, and eliminating the need for the staff to fill the blood collection test tubes of specified colors and types into the corresponding test tube bins in advance as required, and the operation process is simple; by setting a first camera that can be moved laterally, the test tube trays on each tray pushing-in workstation and the plurality of vacuum blood collection tubes inserted on the test tube tray can be photographed as a whole, and then the relevant data such as whether a vacuum blood collection tube is placed in each hole on the test tube tray and the type, model and position of the placed vacuum blood collection tubes can be identified, thereby avoiding This avoids the phenomenon of blood collection failure or even medical accidents caused by the test tube bin and the test tube type not matching, and has strong safety. By setting a test tube clamp that can move in space and cooperating with the data obtained by the first camera, the test tube clamp can be driven to move to the target vacuum blood collection tube for grabbing operation, and the grabbed vacuum blood collection tube is transferred to the labeling position for labeling operation.

Furthermore, to facilitate control of the travel of the Y-axis traversing platform 8, a light-shielding trigger plate is mounted on the pressure plate mounted on the belt. A photoelectric sensor is mounted on the bottom end of the X-axis traversing platform 6 to interact with the light-shielding trigger plate.

[0030] like Figure 2 and Figure 5 As shown, this embodiment further includes an elevating movable base 10 slidably connected to the Y-direction traversing base 8, and a test tube clamp 11 is mounted on the elevating movable base 10. The elevating drive assembly 4 includes a longitudinally arranged elevating guide rail 4-1 fixedly connected to the Y-direction traversing base 8, and the elevating movable base 10 is slidably connected to the elevating guide rail 4-1 via a slider.

[0032] Furthermore, the above-mentioned test tube clamp 11 is connected to the lifting and moving base 10 through the installation angle piece. The above-mentioned test tube clamp 11 adopts an electric clamp, and clamping members are fixedly connected to the two finger ends of the above-mentioned electric clamp. In the actual working process, the above-mentioned two sets of clamping members can be inserted into the gap between the tube bodies of adjacent vacuum blood collection tubes 100 on the test tube tray 3, thereby achieving the purpose of clamping the tube body of the vacuum blood collection tube 100.

[0033] like Figure 5 As shown, in this embodiment, the Y-axis lateral shift seat 8 is an L-shaped structure, and the above-mentioned first camera 9 is installed at the end of the upper structure of the Y-axis lateral shift seat 8.

[0035] During the actual working process, the first camera 9 is set next to the test tube clamp 11 to take a picture of the position of the test tube, and then send the picture to the main control computer for identification and processing. Since the types of vacuum blood collection tubes 100 inserted on different test tube trays 3 are different, they have tube caps of different colors. In this way, the position of the corresponding vacuum blood collection tube 100 can be determined based on the photo. At the same time, given that the position of each tray pushing station for pushing the test tube tray 3 in this embodiment is fixed, it is possible to accurately identify whether a vacuum blood collection tube 100 is placed in each hole on the test tube tray 3 and related data such as the type, model and position of the placed vacuum blood collection tube 100.

[0036] See further Figure 6 The above-mentioned printing and labeling assembly 1 includes a base installed on the mounting base 14, a peeling structure installed on the base, a reeling and unreeling mechanism installed on the base and arranged on both sides of the peeling structure, a printer 1-5 for printing labels, and a clamping roller mechanism installed on the base and located next to the peeling structure, for clamping the vacuum blood collection tube 100 and driving the vacuum blood collection tube 100 to rotate.

[0041] In actual operation, a blood collection tube dispensing box (not shown) for receiving the labeled vacuum blood collection tubes 100 may be placed below the initial position of the test tube clamp 11 .

[0042] Working principle:

[0043] 1) Loading operation: Push multiple test tube trays 3 with several vacuum blood collection tubes 100 inserted into the tray insertion station respectively, and wait for the blood collection operation. The caps of the vacuum blood collection tubes 100 inserted on different test tube trays 3 are different colors;

[0044] 2) Information entry: Enter the type or model of the required vacuum blood collection tube 100, as well as label information;

[0045] 3) Finding the target blood collection tube: The main control computer drives the X-axis drive assembly 5 and the Y-axis drive assembly 7 to operate, thereby driving the test tube clamp 11 and the first camera 9 to move, so that the first camera 9 passes over the multiple tray push-in stations from front to back, and at the same time takes pictures of the entire tray of blood collection tubes below, and sends the pictures to the main control computer, which performs image matching to determine whether they match the input information; if they match, the main control computer calculates the position information of the specific vacuum blood collection tube 100 based on the acquired image, and controls the test tube clamp 11 to move to the target vacuum blood collection tube 100 for clamping operation; if the image information does not match the input information, the first camera 9 is driven to continue to move over the next tray push-in station to take pictures, match the pictures, and determine, until the information matches and the test tube clamping operation is performed;

[0046] 4) Blood collection tube labeling operation: After the test tube gripper 11 grabs the target vacuum blood collection tube 100, the main control computer drives the X-axis drive assembly 5 and the Y-axis drive assembly 7 to operate, thereby driving the test tube gripper 11 to move to the initial position and then to the printing and labeling assembly 1. The vacuum blood collection tube 100 is inserted between the active roller 1-4 and two sets of driven rollers 1-11 in the printing and labeling assembly 1, thereby clamping the vacuum blood collection tube 100. The roller motor 1-6, printer 1-5, and rewinding mechanism are then started to stick the printed label to the tube wall of the vacuum blood collection tube 100. The rotating rollers firmly stick the label to the tube wall of the vacuum blood collection tube 100.

[0047] 5) Blood collection tube dispensing: The printing and labeling assembly 1 then stops rotating the vacuum blood collection tube 100, and the test tube clamp 11 grips the vacuum blood collection tube 100. The printing and labeling assembly 1 releases the grip of the vacuum blood collection tube 100, allowing the X-axis drive assembly 5, the Y-axis drive assembly 7, and the lifting drive assembly 4 to drive the vacuum blood collection tube 100 grasped by the test tube clamp 11 to move to the dispensing box for dispensing the test tubes, thereby releasing the vacuum blood collection tube 100.

[0048] 6) If the type or quantity of blood collection tubes in the information entry step is more than one, repeat steps 3 to 5;

[0049] 7) Reset operation: After completing the work, the main control computer drives the X-axis drive assembly 5, the Y-axis drive assembly 7 and the lifting drive assembly 4 to move the test tube clamp 11 and the first camera 9 to the initial position, thereby achieving reset.

[0050] Example 2:

[0051] like Figure 1 As shown, based on the above embodiment 1, multiple groups of second cameras 12 are further included on the mounting bracket 13, and the multiple groups of second cameras 12 are respectively arranged in a one-to-one correspondence with the multiple groups of tray pushing stations.

[0052] Furthermore, in this embodiment, an aluminum profile rail is mounted on the top surface of the mounting bracket 13. The aluminum profile rail extends in the X direction, and each second camera 12 is mounted on this profile, thereby facilitating adjustment of the position of each second camera 12 in the X direction. Furthermore, to protect each second camera 12, multiple camera brackets are mounted on the aluminum profile rail, and each second camera 12 is mounted within a corresponding camera bracket.

[0053] Each second camera 12 is used to capture images of the test tube tray 3 and several vacuum blood collection tubes 100 placed on the tray pushing station below it, and transmit the images to the main control computer, thereby identifying the number of blood collection test tubes and the color of the tube caps on the corresponding tray pushing station, and storing the information. At the same time, the identified information can be transmitted to the display screen of the main control computer, which is convenient for the staff to observe the inventory of vacuum blood collection tubes 100 in the labeling device in real time, so that medical staff can perform loading operations in a timely manner.

[0054] Working principle:

[0055] 1) Loading operation: Push multiple test tube trays 3 with several vacuum blood collection tubes 100 inserted into the tray insertion station respectively, waiting for the blood collection operation. The caps of the vacuum blood collection tubes 100 inserted on different trays are different colors;

[0056] 2) Information Collection: Each second camera 12 takes a picture of the blood collection tubes on the tray push-in station below it, and transmits the picture to the main control computer for analysis, and then stores the number and tube cap color of the blood collection tubes on each tray push-in station;

[0057] 3) Information entry: Enter the type or model of the required vacuum blood collection tube 100, as well as label information;

[0058] 4) Information comparison: The input information of the required test tube is compared with the image information on each tray push-in station; if the type matches, the position of the matching blood collection test tube is calculated based on the acquired image, and the X-axis drive assembly 5 and the Y-axis drive assembly 7 are driven, thereby driving the first camera 9 and the test tube clamp 11 to move to the target blood collection test tube;

[0059] 5) Grabbing the target blood collection tubes: The main control computer controls the test tube gripper 11 and the first camera 9 to move to the matching tray push-in station. At the same time, the first camera 9 photographs the blood collection tubes on the corresponding tray push-in station. The captured image information is fed back to the main control computer for analysis, and the number and specific location of the target blood collection tubes are determined. The test tube gripper 11 is then driven to grasp the blood collection tubes.

[0060] 6) Blood collection tube labeling operation: The specific operation process is the same as the blood collection tube labeling operation in Example 1;

[0061] 7) Blood collection tube distribution: The specific operation process is consistent with the blood collection tube distribution operation in Example 1;

[0062] 8) If the type or quantity of blood collection tubes in the information entry step is more than one, repeat steps 4 to 7;

[0063] 9) Reset operation: After completing the work, the main control computer drives the X-axis drive assembly 5, the Y-axis drive assembly 7 and the lifting drive assembly 4 to move the test tube clamp 11 and the first camera 9 to the initial position, thereby achieving reset.

[0064] The utility model can quickly realize the loading operation, collect information such as the type, quantity and position of the vacuum blood collection tubes 100 after loading, and grab the target vacuum blood collection tubes 100 for labeling according to the information.
