Description

Technical Field

[0001] The present invention relates to the technical field of medical logistics equipment, and in particular to a specimen tube transmission device, a launching device and a method. Background Art

[0002] At present, some hospitals have begun to use medical logistics transmission systems, which can realize the automatic transmission of items between different floors and rooms in the hospital. This has effectively improved the efficiency of logistics transmission in the hospital and ensured the safety of item transmission. For specimen tubes such as blood collection tubes, the timeliness of transmission is higher, and pneumatic tube logistics transmission systems are generally used for transportation. The pneumatic tube logistics transmission system uses compressed air as power to transmit the specimen tube at high speed along the pipeline, greatly improving the transmission efficiency and fully meeting the timeliness requirements of specimen tube transmission.

[0003] Among them, the specimen tube needs to be launched into the pipeline through the launching device, and the launching device is responsible for the loading, transmission, and launching of the specimen tube. The posture of the specimen tube during the transmission process is relatively messy. When launching the specimen tube into the pipeline, the cap of the specimen tube is advanced and the tube body is backward, which can avoid the risk of the cap falling off during the transportation process. The current launching equipment needs to be equipped with a more complex direction adjustment device with a sensor device to realize the direction adjustment operation of the specimen tube. The direction adjustment device has a complex structure, high cost, and complex direction adjustment operation, which makes the launch equipment operate inefficiently. Summary of the invention

[0004] The object of the present invention is to provide a specimen tube transmission device, a launching device and a method, so as to adjust the orientation of the tube cap of the specimen tube to be consistent during the specimen tube transmission process.

[0005] In order to achieve the above object, the technical solutions adopted by the present invention are as follows:

[0024] Further, the direction from the upper position of the two scanning support rods toward the upper position of the posture adjustment opening is defined as from inside to outside;

[0025] A pipe blocking frame is arranged on the outer edge of the posture adjustment opening on the material shifting frame.

[0026] A specimen tube launching device is provided with the specimen tube transmission device mentioned above.

[0027] A specimen tube transmission method, using the above-mentioned specimen tube launching device, comprises the following steps:

[0047] The support seat 201 is set on the frame 1, and the two ends of the scanning support rod 202 are rotatably connected to the support seat 201 through bearings 2021. Two scanning support rods 202 are set, and the two scanning support rods 202 are arranged side by side. There is a gap between the two scanning support rods 202, and the gap does not allow the specimen tube 4 to pass through.

[0048] The first driving mechanism is disposed on the support base 201 , and drives the two scanning rods 202 to rotate relative to the support base 201 .

[0049] The first driving mechanism includes a motor 2051, a reducer 2052, a driving pulley 2053, a passive pulley 2054 and a conveyor belt 2055. The motor 2051 is arranged on the reducer 2052, and the reducer 2052 is arranged on the support base 201. The output end of the motor 2051 is connected to the input end of the reducer 2052, and the output end of the reducer 2052 is connected to the driving pulley 2053. One end of the scanning support rod 202 is connected to the passive pulley 2054, and the conveyor belt 2055 is connected between the driving pulley 2053 and the passive pulley 2054. The output end of the motor 2051 rotates, and after being decelerated by the reducer 2052, the driving pulley 2053 drives the passive pulley 2054 to rotate, and then drives the scanning support rod 202 to rotate relative to the support base 201.

[0050] The scanner 5 is arranged on the frame 1, and the scanner 5 is located above the scanning support rod 202, and the scanning end of the scanner 5 is facing the gap between the two scanning support rods 202; the scanning support rod 202 rotates relative to the support seat 201, driving the specimen tube 4 on the scanning support rod 202 to flip over, and during the flipping process of the specimen tube 4, the scanner 5 scans and records the barcode information on the specimen tube 4.

[0051] The scanning chamber 203 is provided with an opening which passes through the upper and lower parts, and the opening allows the specimen tube 4 to pass through. The scanning chamber 203 is in a rectangular frame structure, so that the structure itself is relatively firm.

[0052] The second driving mechanism is disposed on the support base 201 , and drives the scanning chamber 203 to move to a position above the two scanning rods 202 , or drives the scanning chamber 203 to leave the position above the two scanning rods 202 and move to a position above the posture adjustment opening 3011 .

[0053] The second driving mechanism is configured as an electric cylinder 206. An L-shaped support frame 2012 is provided on the support base 201. The cylinder end of the electric cylinder 206 is provided on the support frame 2012. The telescopic end of the electric cylinder 206 is connected to the scanning chamber 203. The telescopic end of the electric cylinder 206 telescopes relative to the cylinder end to drive the scanning chamber 203 to move to a position above the two scanning support rods 202, or to drive the scanning chamber 203 to leave the position above the two scanning support rods 202 and move to a position above the posture adjustment opening 3011.

[0054] In this embodiment, a through hole 2013 is provided on the support base 201, and the scanning chamber 203 can pass through the through hole 2013. Slide blocks 2031 are provided on opposite sides of the scanning chamber 203, and slide grooves 2011 are provided on opposite sides of the support base 201. The slide blocks 2031 on the same side slide with the slide grooves 2011. When the telescopic end of the electric cylinder 206 drives the scanning chamber 203 to move, the slide blocks 2031 slide relative to the slide grooves 2011.

[0055] The material shifting frame 301 is provided with a posture adjustment opening 3011, which is connected from top to bottom, and a posture adjustment baffle 302 is arranged on the inner wall of the posture adjustment opening 3011. When the specimen tube 4 falls into the posture adjustment opening 3011, the posture adjustment baffle 302 is used to abut the tube cap of the specimen tube 4.

[0056] The posture adjustment baffle 302 is arranged in a ring shape along the inner wall of the posture adjustment opening 3011 , so that the posture adjustment baffle 302 can stably support the specimen tube 4 .

[0057] The attitude adjustment baffle 302 is located at the lower end of the inner wall of the attitude adjustment opening 3011, so that the side of the cap of the specimen tube 4 abuts against the inner wall of the attitude adjustment opening 3011, and the attitude adjustment opening 3011 guides and limits the specimen tube 4, so that the specimen tube 4 is stably in a posture with the cap facing upwards, the tube body facing in the direction, and the specimen tube 4 remains vertical.

[0058] One side end face of the material shifting frame 301 is provided with a pipe outlet 3012, and the posture adjustment opening 3011 extends toward one side end face of the material shifting frame 301. The posture adjustment opening 3011 is in the shape of an elongated strip, and the posture adjustment opening 3011 is connected with the pipe outlet 3012. In this way, the specimen tube 4 in the posture adjustment opening 3011 can be removed from the pipe outlet 3012.

[0059] The direction from the upper position of the two scanning support rods 202 to the upper position of the posture adjustment opening 3011 is defined as from inside to outside, and a tube blocking frame 3013 is provided on the material transfer rack 301 at the outer edge of the posture adjustment opening 3011. When the specimen tube 4 continues to fall from the opening of the scanning chamber 203 and falls into the posture adjustment opening 3011, the tube blocking frame 3013 implements buffering and blocking of the specimen tube 4, so that the specimen tube 304 slightly hits the tube blocking frame 3013 and then falls into the posture adjustment opening 3011, thereby improving the accuracy of the specimen tube 304 entering the posture adjustment opening 3011, thereby improving the stability of the specimen tube launching device.

[0060] The material-moving mechanism drives the specimen tube 4 in the posture-adjusting opening 3011 to move out from the tube outlet 3012 .

[0061] The material shifting mechanism comprises a motor 3031, a motor seat 3032, a driving pulley 3033, a driven pulley 3034, a conveyor belt 3035 and a shift fork 3036. The motor 3031 is arranged on the motor seat 3032, and the driving pulley 3033 and the driven pulley 3034 are both rotatably connected to the material shifting frame 301. The output end of the motor 3031 is connected to the driving pulley 3033, and the conveyor belt 3035 is connected between the driving pulley 3033 and the driven pulley 3034, and the extending direction of the conveyor belt 3035 is the same as the extending direction of the posture adjustment opening 3011. The shift fork 3036 is arranged on the conveyor belt 3035, and the shift fork 3036 can push the specimen tube 4 in the posture adjustment opening 3011 to move out from the pipe outlet 3012.

[0062] The output end of the motor 3031 drives the driving pulley 3033 to rotate, and the driving pulley 3033 drives the conveyor belt 3035 to move, and the conveyor belt 3035 drives the shift fork 3036 thereon to move, and the shift fork 3036 abuts against the specimen tube 4 and drives the specimen tube 4 to move.

[0063] A specimen tube launching device is disclosed. A loading device 6 and a launching device 7 are arranged on a frame 1 of the specimen tube launching device. The frame 1 is also provided with the specimen tube transmission device mentioned above in this embodiment.

[0064] A specimen tube transmission method, using the specimen tube launching device described above in this embodiment, comprises the following steps:

[0065] Step 1: The second driving mechanism drives the scanning chamber 203 to move to the position above the two scanning support rods 202. After the specimen tube 4 comes from the previous link (loading device 6), the specimen tube 4 passes through the opening of the scanning chamber 203 and falls onto the scanning support rod 202. The first driving mechanism drives the scanning support rod 202 to rotate, and the specimen tube 4 turns over in the gap between the two scanning support rods 202. While turning over, the scanner 5 scans and records the barcode information on the specimen tube 4.

[0066] Step 2: The second driving mechanism drives the scanning chamber 203 to separate from the upper position of the two scanning support rods 202 and move to the upper position of the posture adjustment opening 3011. The specimen tube 4 moves horizontally out from the scanning support rod 202 and continues to fall from the opening of the scanning chamber 203 and falls into the posture adjustment opening 3011. The tube body of the specimen tube 4 passes through the posture adjustment opening 3011, and the tube cap of the specimen tube 4 is abutted by the posture adjustment baffle 302. The specimen tube 4 is adjusted to a posture in which the tube cap faces upward and the tube body faces in the vertical direction and the specimen tube 4 remains vertical.

[0067] Step 3: Driven by the material-dispensing mechanism, the specimen tube 4 in the posture-adjusting opening 3011 is moved out of the tube outlet 3012 and pushed to the next link (launching device 7). It should be noted that the cap orientation of the specimen tube 4 does not need to be adjusted in the next link (launching device 7).

[0068] So far, the present embodiment has been described in detail in conjunction with the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the specimen tube transmission device, the launching device and the method of the present invention. The specimen tube transmission device, the launching device and the method of the present invention, the second driving mechanism drives the scanning chamber 203 to move to the position above the two scanning support rods 202. After the specimen tube 4 comes over from the previous link (loading device 6), the specimen tube 4 passes through the opening of the scanning chamber 203 and falls onto the scanning support rod 202. The first driving mechanism drives the scanning support rod 202 to rotate, and the specimen tube 4 flips in the gap between the two scanning support rods 202. While flipping, the scanner 5 scans and records the bar code information on the specimen tube 4; the second driving mechanism drives the scanning chamber 203 to leave the position above the two scanning support rods 202 and move to the position of the posture adjustment opening 3011. At the upper position, the specimen tube 4 is horizontally moved out from the scanning support rod 202 and continues to fall from the opening of the scanning chamber 203 and falls into the position of the posture adjustment opening 3011. The specimen tube 4 can basically maintain a horizontal posture during the falling process, so that the posture of the specimen tube 4 when falling into the posture adjustment opening 3011 is relatively simple; the tube body of the specimen tube 4 passes through the posture adjustment opening 3011, and the tube cap of the specimen tube 4 is abutted by the posture adjustment baffle 302, and the specimen tube 4 is adjusted to a posture in which the tube cap faces upward, the tube body faces upward, and the specimen tube 4 maintains a vertical posture; driven by the material-dispensing mechanism, the specimen tube 4 in the posture adjustment opening 3011 is moved out from the tube outlet 3012 and pushed to the next link (launching device). In this way, the tube cap of the specimen tube 4 is adjusted to a consistent direction during the transmission process of the specimen tube 4.
