Description

Technical Field

[0001] The present application relates to the field of pneumatic logistics technology, and in particular to a medical specimen pneumatic launching device and a pneumatic transmission system using the device. Background Art

[0002] At present, with the continuous growth of the number of hospital test specimens, traditional manual transportation can no longer meet the logistics needs of hospitals, and large hospitals have begun to deploy pneumatic tube logistics transmission systems. At present, the implementation method of pneumatic tube logistics transmission systems is mostly transmission bottle pneumatic transmission systems, which have the advantages of fast transmission speed, easy cleaning, low cost, etc., and the disadvantages are that the workflow is relatively cumbersome, the error rate is high, and the efficiency is low. As clinical laboratories have higher and higher requirements for the circulation time, timeliness, and traceability of specimens, traditional logistics transmission methods can no longer fully meet the needs of clinical laboratories. China has begun to develop a single specimen pneumatic transmission system for the transmission of test specimens. The system mainly includes an air compressor, a specimen transmitter, a transmission pipeline, a specimen receiver, etc.

[0003] Regarding the specimen transmitting end equipment, the Chinese invention patent with the authorization publication number CN115465669A discloses a pneumatic logistics transmission and sending device for specimen tubes, which includes a shell with a feeding door on the shell for feeding the specimen tubes into the shell. The shell is provided with a material sorting unit, a feeding unit, a material dialing unit and a transmitting unit. The material sorting unit is used to sort the posture of the specimen tubes entering the shell so that the specimen tubes enter the feeding unit in a horizontal state, and then use a barcode scanner at the feeding unit to scan the barcode on the specimen tube and upload it to the system. After scanning the code, the material dialing unit dials the specimen tube into the transmitting unit, and the specimen tube is blown into the transmitting transmission pipeline by blowing compressed air through the transmitting unit. The compressed air is continuously blown to transport the specimen tube to the destination.

[0004] In response to the above-mentioned related technologies, the inventors found that when multiple specimen tubes enter the launch transmission pipeline, some may have the tube caps in front, and some may have the tube caps in the back. These irregular arrangements will cause unstable air pressure in the launch transmission pipeline, affecting the transmission stability of the specimen tubes. In addition, for those specimen tubes with the tube caps in the back, the front side of the tube cap will be subjected to pressure from the air in front during the forward process, resulting in the possibility of detachment from the tube body, which reduces the safety of specimen transmission.

Since the width of the adjustment slot is not less than the diameter of the specimen tube body but less than the diameter of the tube cap, no matter whether the specimen tube enters the adjustment slot with the tube body in front or the tube cap in front, the tube body of the specimen tube will pass through the adjustment slot, and the tube cap will be stuck on the adjustment slot At this time, the posture of the specimen tube is unified, that is, the tube cap is on top. At this time, the specimen tube is continued to be pushed, and the specimen tube slides vertically from one end of the expanded opening of the adjustment slot into the reversing launching mechanism. At this time, the reversing launching mechanism launches the specimen tube with the tube cap in front, so that the specimen tubes are regularly arranged in the pipeline, maintaining the stability of the air pressure in the pipeline, thereby ensuring the stability of the specimen tube transmission in the pipeline. At the same time, because the tube cap is in the front, the cap of the specimen tube is prevented from falling off the tube body, thereby improving the safety of specimen transmission.

[0008] Optionally, a guide rail is connected to the adjustment box by bolts, and the guide rail is parallel to the opening direction of the adjustment slot.

[0010] Optionally, a support seat is provided on the back of the material sorting mechanism, and the support seat is fixedly connected to the launch box. The top surface of the support seat is lower than the top surface of the material sorting mechanism. An installation groove is opened on the top surface of the support seat, and a barcode scanner is provided in the installation groove. The adjustment box is located at one end of the support seat, and the guide rail is installed on the support seat and the adjustment box.

[0011] By adopting the above technical solution, after the specimen tubes are sorted by the material sorting mechanism, they are lifted one by one to the highest point of the material sorting mechanism, and then rolled along the material sorting mechanism to the support seat.

[0013] By adopting the above technical solution, the specimen tube is lifted by the feeding mechanism and rolled between the two guide rollers. At this time, the barcode on the specimen tube may not be facing the barcode scanner, and the turning motor drives a guide roller to rotate through a belt, and the guide roller drives the specimen tube to turn over. During the rotation process, when the barcode on the specimen tube is aligned with the barcode scanner below, the scanning can be completed, thereby facilitating the scanning of the barcode on the specimen tube, avoiding the situation where the specimen tube is not scanned, and improving the accuracy and completion of the scanning.

[0015] By adopting the above technical solution, the reversing block can slide in the launching box. When the fixed groove of the reversing block is aligned with the opening below the material guide cylinder, the specimen tube in the material guide cylinder passes through the drop opening and falls into the fixed groove. At this time, the reversing block moves in the direction close to the launching tube. When it moves to the fixed groove and is aligned with the launching hole and the air supply hole, compressed air is sent into the air supply hole to blow the specimen tube into the launching tube with the tube cap in front. At this time, the reversal of the specimen tube is completed, and it is adjusted to the posture with the tube cap in front. The reversal of the specimen tube can be completed, and it can be transmitted with the tube cap in front, avoiding pressure on the connection between the tube cap and the tube body, ensuring the firmness of the connection between the tube cap and the tube body, and thus ensuring the safety of the specimen during the transmission process.

[0016] Optionally, both ends of the launch box are provided with air jets, and driving nozzles are installed in the two air jets, and the driving nozzles are used to introduce compressed air.

[0017] By adopting the above technical solution, compressed air is introduced into the driving nozzles at both ends of the launch box, so that the reversing block can be driven to slide back and forth in the launch box, so that the specimen tube can be transported from under the guide cylinder to the launch tube, completing the transfer and reversal of the specimen tube.

[0018] In a second aspect, the present application provides a pneumatic transmission system using a medical specimen pneumatic transmitting device, which adopts the following technical solution: A pneumatic transmission system using a medical specimen pneumatic launching device comprises a specimen launching device, a specimen receiving device, a transmission pipeline and an air compressor, wherein the air supply hole is connected to the air compressor via a pipeline, the driving nozzle is connected to the air compressor via a pipeline, the launching tube of the specimen launching device and the specimen receiving device are connected via a transmission pipeline, and the air compressor is used to provide compressed air to the entire system.

[0019] By adopting the above technical scheme, the launching tube of the specimen launching device is connected with the transmission pipeline, the specimen tube enters into the transmission pipeline through the launching tube, is transmitted with the tube cap in front, and then enters into the receiving device through the transmission pipeline. During this process, the air compressor provides compressed air to the entire system. When the specimen tube arrives at the specimen receiving device, the inspector can take the specimen out of the receiving device for inspection, or connect the specimen receiving device to the hospital's existing automated specimen processing equipment. After arriving, the specimen tube can directly enter the next-level processing equipment without human intervention, thereby realizing automated and integrated transmission and processing of specimens, thereby improving medical efficiency.

[0020] Optionally, it also includes a converter, which includes a transmitting converter and a receiving converter.

[0021] By adopting the above technical solution, when one specimen transmitting device and multiple specimen receiving devices are arranged in the same system, the system selects a receiving converter, which is used to divide the transmission path into two, that is, the specimen tube emitted from the specimen transmitting device is transported to the first receiving converter through the transmission pipeline, and then it is split by the receiving converter and transmitted to two transmission pipelines respectively, one of which is transported to the first specimen receiving device, and the other continues to be transported and transmitted to the second receiving converter, and then it is split by the second receiving converter and divided into two transmission paths, one is transported to the second specimen receiving device and the other is transported to the third receiving converter... and the switching is continuously performed until it is transported to the specimen receiving device to be delivered; When one specimen receiving device and multiple specimen transmitting devices are arranged in the same system, the system uses a transmitting converter, which is used to combine the two transmission paths into one, that is, the specimen tubes emitted from the first and second specimen transmitting devices enter two different transmission pipelines respectively, and the two transmission pipelines are connected to the first transmitting converter. The specimen tubes transported by the two transmission pipelines are collected together through the first transmitting converter and output from the same transmission pipeline, and then enter the second transmitting converter, and the specimen tubes emitted by the third specimen transmitting device are also transported to the second transmitting converter through the transmission pipeline, and the second transmitting converter collects and transports them to the third transmitting converter... and the collection is continued until the specimen tubes emitted by all the specimen transmitting devices are transported to the specimen receiving device; When multiple specimen transmitting devices and multiple specimen receiving devices are set in the same system, the system selects a transmitting converter and a receiving converter, and gradually aggregates the transmission paths of multiple specimen transmitting devices to the last transmitting converter through the transmitting converter, and then gradually divides them through multiple receiving converters, so as to transport the specimens to the corresponding specimen receiving devices; Different converters and the number of converters are selected according to the number of specimen transmitting devices and specimen receiving devices in the system, so as to form a specimen ladder transmission network, realize the unified transmission and management of specimen transmitting devices in different locations, or timely and fixed-point delivery of specimen receiving devices in different locations, further improving the automation level and intelligent management level of specimen transmission, and improving medical efficiency and the degree of medical informatization.

The switching cylinder is used to drive the switching block to slide, and the switching cylinder is electrically connected to the barcode scanner.

[0023] By adopting the above technical solution, the barcode scanner is electrically connected to the switching cylinder of the receiving converter. After the barcode scanner scans the barcode on the specimen tube in real time, the information of the specimen tube is synchronously uploaded to the system, and then compared with the specimen category built into the system or provided by the hospital HIS system, so as to complete the judgment of the specimen tube category, and automatically judge the specimen receiving device that needs to be reached according to different categories, and automatically select the middle transmission path based on this, and then the switching cylinder drives the switching block to slide, so that the feed hole and the discharge hole of the corresponding transmission path are connected, thereby realizing the fixed-point transportation of specimen tubes of different categories, improving the efficiency and accuracy of specimen transmission, and thus improving the intelligence level of specimen transmission.

[0024] Optionally, the specimen receiving device includes a receiving box, a material taking port is opened on the receiving box, a receiving tube is arranged on the receiving box, the receiving tube is connected to the transmission pipeline, the air compressor can deliver compressed air to the bottom of the receiving tube through the pipeline, three groups of infrared sensors are arranged in the receiving tube along its axial direction, the three groups of infrared sensors are respectively arranged as the first group, the second group and the third group from bottom to top, the interval between the first group of infrared sensors and the second group of infrared sensors is the length of a single specimen tube, the interval between the second group and the third group is less than the length of a single specimen tube, and the three groups of infrared sensors judge the number of arrived specimen tubes by triggering recognition and the time when recognition disappears.

[0025] By adopting the above technical solution, in order to avoid the situation where multiple specimen tubes are abutted end to end during the transmission process and are mistakenly identified as one, three groups of infrared sensors are set to judge the number of specimen tubes arriving at the specimen receiving device. The specific judgment is as follows: when the first and second groups of infrared sensors recognize the signal at the same time, and the third group of infrared sensors does not recognize the signal, the system recognizes that one specimen tube has arrived; when the three groups of infrared sensors recognize the signal at the same time, the system will judge according to the following logics: within the first unit time range, the three groups of infrared sensors are triggered and disappear at the same time, and the system recognizes that two specimen tubes have arrived; within the first unit time range, the three groups of infrared sensors are triggered and disappear at the same time, and the system recognizes that two specimen tubes have arrived. The infrared sensors are triggered at the same time and do not disappear, and the system recognizes that three specimen tubes have arrived; within the second unit time range, the three groups of infrared sensors are triggered at the same time and disappear, and the system recognizes that four specimen tubes have arrived; within the second unit time range, the three groups of infrared sensors are triggered at the same time and do not disappear, and the system recognizes that five specimen tubes have arrived... The system can set the length of the unit time according to the number of specimen tubes continuously emitted by the specimen transmitting device, and increase the number of unit times used for judgment, so as to more accurately judge the number of specimen tubes arriving at the specimen receiving device, avoid misjudgment due to the end-to-end contact of the specimen tubes, and ensure the stable operation of the transmission system.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Since the width of the adjustment groove is not less than the diameter of the specimen tube body but less than the diameter of the tube cap, no matter whether the specimen tube enters the adjustment groove with the tube body in front or the tube cap in front, the tube body of the specimen tube will pass through the adjustment groove, and the tube cap will be stuck on the top of the adjustment groove. At this time, the posture of the specimen tube is unified, that is, the tube cap is on top. At this time, the specimen tube is continued to be pushed, and the specimen tube slides vertically from one end of the expanded opening of the adjustment groove into the reversing launching mechanism. At this time, the reversing launching mechanism launches the specimen tube with the tube cap in front, so that the specimen tubes are regularly arranged in the pipeline, maintaining the stability of the air pressure in the pipeline, thereby ensuring the stability of the specimen tube transmission in the pipeline. At the same time, because the tube cap is in front, the tube cap of the specimen tube is prevented from falling off from the tube body, thereby improving the safety of specimen transmission; 2.

DETAILED DESCRIPTION

[0029] After receiving multiple specimen tubes, the specimen transmitting device in the single specimen pneumatic transmission system generally needs to adjust its posture first to facilitate the subsequent scanning and transmitting operations of the single specimen tube.

[0030] At present, a common method for sorting specimen tubes is the push plate lifting method, and its working principle is as follows: an inclined material sorting bin is provided in the housing, and multiple fixed plates are provided in the material sorting bin. A push plate is provided on the side of each fixed plate close to the material sorting bin, and the push plate can slide in the vertical direction relative to the fixed plate. The width of the top surface of the push plate and the fixed plate is adapted to the width of a specimen tube, and the side of the top surface of the push plate and the fixed plate away from the material sorting bin is tilted downward. In the initial state, the top surface of the push plate closest to the sorting bin is located at the bottom of the sorting bin, and a specimen tube slides along the inclined surface and falls on the push plate. At this time, all push plates slide upward and stop when they are flush with the adjacent fixed plate. The specimen tube on the push plate falls on the adjacent fixed plate due to inertia and the inclined surface of the push plate. At this time, all push plates slide down again until the top surface is flush with the top surface of the previous fixed plate. The specimen tube on the fixed plate slides to the next push plate due to the inclined surface on the fixed plate. This cycle repeats until the specimen tube is continuously lifted to the top of the fixed plate at the top, and then slides along the inclined surface of the top of the fixed plate to the feeding unit, and scans the barcode on the tube body. During the sorting process, the specimen tube is combed and adjusted from various postures to a horizontal posture with the peripheral side wall abutting the fixed plate or push plate, while ensuring that the specimen tubes are lifted one by one in an orderly manner and sent to the feeding unit.

[0031] The following is combined with Figure 1-15 This application is described in further detail. Example 1

[0032] Example 1 of the present application discloses a medical specimen pneumatic launching device.

[0033] Reference Figure 1 , Figure 2 and Figure 3A medical specimen pneumatic launching device includes a launching box 11, a touch screen is arranged on one side of the top of the launching box 11, and a feeding port 111 is opened on the other side. A cover plate 112 is hinged on the feeding port 111. After the cover plate 112 is opened, a specimen tube can be put into the launching box 11 from the feeding port 111. A feeding box 12 is arranged on the top of the launching box 11, and a supporting frame 13 is arranged on the bottom. A feeding port 121 is arranged on the back of the feeding box 12 away from the feeding port 111, and a material handling mechanism 14 is arranged in the feeding port 121. The bottom surface of the inner wall of the feeding box 12 is provided with a first material guide step 122 and a second material guide step 123. The first material guide step 122 is arranged to be tilted downward in the direction from the feeding port 111 to the material sorting mechanism 14. The second material guide step 123 is located in front of the material sorting mechanism 14 and is arranged to be tilted downward in the direction from the front of the launch box body 11 to the back of the launch box body 11. The second material guide step 123 is lower than the first material guide step 122. A scanning mechanism 15 is arranged on the top of the feeding port 121. The scanning mechanism 15 is located on the back of the material sorting mechanism 14. An adjustment mechanism 16 and a reversing launching mechanism 17 are arranged on the support frame 13. The adjustment mechanism 16 is located on the back of the scanning mechanism 15. The reversing launching mechanism 17 is located outside the feeding box 12 and between the first material guide step 122 and the outer wall of the feeding port 121.

[0034] The specimen tube is put into the feeding box 12 from the feeding port 111, slides down the first material guide step 122 to the second material guide step 123, and then slides along the second material guide step 123 to the bottom of the material sorting mechanism 14. The material sorting mechanism 14 adjusts the posture of the specimen tube to make it horizontal, and lifts the specimen tubes one by one to the scanning mechanism 15. The scanning mechanism 15 scans and identifies the barcode on the specimen tube and uploads it to the control system to record the information of the specimen tube. After scanning, the adjustment mechanism 16 adjusts the posture of the specimen tube to a vertical state with the tube cap on top, and falls into the reversing launch mechanism 17. The reversing launch mechanism 17 then changes the sliding direction of the specimen tube so that it is launched with the tube cap in front.

[0035] Reference Figure 2 and Figure 4The material sorting mechanism 14 adopts a push plate lifting structure, and the specific structure is the existing technology and will not be repeated here. The scanning mechanism 15 includes a support seat 151, a barcode scanner 153 and a material turning assembly. The support seat 151 is fixedly connected to the inner wall of the feeding port 121 and is located on the back of the uppermost fixed plate 141 in the material sorting mechanism 14. The top surface of the support seat 151 is provided with a mounting groove 152 for mounting the barcode scanner 153. The length direction of the support seat 151 is parallel to the width direction of the material sorting mechanism 14. The turning assembly includes two guide rollers 154 rotatably connected to the top of the support seat 151. The two guide rollers 154 are located above the barcode scanner 153. The two guide rollers 154 are arranged in parallel and their axial direction is parallel to the length direction of the support seat 151. The two guide rollers 154 are arranged at an interval and the interval width is smaller than the diameter of the specimen tube body. The top of the guide roller 154 is flush with the lowest point of the top surface of the uppermost fixed plate 141, so that the specimen tube can slide between the two guide rollers 154 along the inclined top surface of the fixed plate 141. A turning motor 155 is installed on the inner wall of the feed port 121, and the turning motor 155 drives one of the guide rollers 154 to rotate through a belt. An infrared detector 156 is installed at the end of the support seat 151 away from the adjustment mechanism 16, which is used to identify whether there is a specimen tube on the two guide rollers 154 and is electrically connected to the turning motor 155.

[0036] After the specimen tubes are sorted by the material sorting mechanism 14, they are lifted one by one to the scanning mechanism 15. The specimen tubes on the uppermost fixed plate 141 slide along the inclined surface to between the two material guide rollers 154. At this time, the infrared detector 156 recognizes the specimen tube and controls the material turning motor 155 to start. The material turning motor 155 drives a material guide roller 154 to rotate through a belt, and the material guide roller 154 drives the specimen tube to turn over. During the rotation process, when the barcode on the specimen tube is aligned with the scanner 153 below, the scanner 153 scans it to record the information of the specimen tube.

[0037] Reference Figure 2 , Figure 4 and Figure 5The adjustment mechanism 16 includes an adjustment cylinder 161, a push rod 162, a guide, a push block 163 and an adjustment box 164. The adjustment box 164 is fixedly connected to the end of the support seat 151 away from the infrared detector 156. The adjustment cylinder 161 is connected to the side of the support seat 151 away from the material handling mechanism 14 by bolts, and the telescopic axis of the adjustment cylinder 161 is set downward. The first connecting plate 131 is fixedly connected to the support frame 13. The bottom of the push rod 162 is rotatably connected to the first connecting plate 131. The push rod 162 is L-shaped. The bottom of the push rod 162 is close to the end of the adjustment cylinder 161 and is bent toward the adjustment cylinder 161. The bent end is hinged to the telescopic axis of the adjustment cylinder 161. The top of the push rod 162 is provided with a limiting groove 1621 along its length. The guide member includes a slider 1661 and a guide rail 167. The guide rail 167 is fixedly connected to the support seat 151 and the adjustment box 164 on the side away from the material sorting mechanism 14, and the length direction of the guide rail 167 is parallel to the axial direction of the material guide roller 154. The slider 1661 is slidably connected to the guide rail 167. The slider 1661 is fixedly connected to a slide bar 1662, and the slide bar 1662 is slidably connected to the limit groove 1621. The push block 163 is fixedly connected to the slider 1661, and the push block 163 is located above the two material guide rollers 154. A detection hole 1631 is opened at the bottom of the push block 163, and the infrared rays emitted by the infrared detector 156 pass through the detection hole 1631 to reach the specimen tube.

[0038] When the specimen tube is scanned, the slider 1661 is located at one end of the guide roller 154 close to the infrared detector 156, which is the starting position. After the specimen tube is scanned on the guide roller 154, the telescopic shaft of the adjustment cylinder 161 is extended to drive the bottom of the push rod 162 to rotate downward, thereby driving the top of the push rod 162 to rotate toward the direction close to the adjustment box 164. The push rod 162 drives the slider 1661 from the starting position to the direction close to the adjustment box 164 through the slide bar 1662. When it moves to the point where the push block 163 abuts against the specimen tube, the push block 163 pushes the specimen tube to slide toward the direction close to the adjustment box 164, thereby sending the specimen tube to the adjustment box 164.

[0039] Reference Figure 6 The top of the adjustment box 164 is provided with an adjustment slot 1641 along the length direction of the guide rail 167. The adjustment slot 1641 is provided between the two guide rollers 154. The width of the adjustment slot 1641 is not less than the diameter of the specimen tube body and less than the diameter of the tube cap. The opening of the end of the adjustment slot 1641 away from the guide roller 154 is enlarged and larger than the area of ​​the specimen tube cap, so that the specimen tube can fall. The bottom of the adjustment box 164 is provided with a discharge port 1642 at the end corresponding to the enlarged opening of the adjustment slot 1641. The discharge port 1642 is fixedly connected to a guide cylinder 165, and the bottom of the guide cylinder 165 is inclined toward the center thereof.

[0040] When the push rod 162 pushes the slider 1661 to continue to slide to the guide rail 167 on the adjustment box 164, the specimen tube enters the adjustment slot 1641 at this time. Since the width of the adjustment slot 1641 is not less than the diameter of the specimen tube body but less than the diameter of the tube cap, no matter whether the specimen tube enters the adjustment slot 1641 with the tube body in front or the tube cap in front, the tube body of the specimen tube will pass through the adjustment slot 1641, and the tube cap will be stuck on the top of the adjustment slot 1641. At this time, the posture of the specimen tube is unified, that is, the tube cap is on top. At this time, the slider 1661 continues to push the specimen tube, and the specimen tube slides vertically from the opening at the tail of the adjustment slot 1641, and slides along the inner wall of the guide barrel 165 into the reversing launch mechanism 17.

[0041] Reference Figure 5 When the push block 163 pushes the specimen tube into the guide cylinder 165, the position of the slider 1661 is the end position. The feeding box 12 and the adjustment box 164 are fixedly connected with brackets 168. The two brackets 168 are installed with travel limiters 169 corresponding to the starting position and the end position. The travel limiter 169 is located above the slider 1661. The two travel limiters 169 are electrically connected to the adjustment cylinder 161. When the telescopic shaft of the adjustment cylinder 161 is extended to drive the slider 1661 to move from the starting position to the end position, it means that the posture unification and feeding of a specimen tube are completed. At this time, the travel limiter 169 at the end position records the position of the slider 1661, that is, the telescopic rod of the adjustment cylinder 161 is controlled to retract, driving the slider 1661 to move toward the starting position. When the travel limiter 169 moves to the starting position and records the slider 1661, the adjustment cylinder 161 stops retracting, that is, the reset of the slider 1661 is completed.

[0042] Reference Figure 2 , Figure 6 and Figure 7The reversing launching mechanism 17 includes a launching box 171, a reversing block 172, two driving nozzles 173 and a launching tube 174. The launching box 171 is bolted to the supporting frame 13 through the second connecting plate 132. The launching box 171 is located below the material guide cylinder 165. The launching box 171 is horizontally arranged in the length direction. A material drop opening 1711 is provided on the top surface of the launching box 171 corresponding to the opening below the material guide cylinder 165. The reversing block 172 is slidably connected to the launching box 171. A fixed groove 1721 is vertically provided in the reversing block 172. When the slider 1661 moves to align the fixed groove 1721 with the material drop opening 1711, the specimen tube slides from the material guide cylinder 165 into the fixed groove 1721. Both ends of the fixed groove 1721 are open. Both ends of the launch box 171 are provided with air jets 1712, and two driving nozzles 173 are respectively installed in the two air jets 1712. The two driving nozzles 173 are connected to the air compressor 5 through a pipeline, and the air compressor 5 provides compressed air to them, thereby pushing the reversing block 172 to slide back and forth in the launch box 171. The launch tube 174 is connected to the top of the launch box 171 by bolts and extends from the top surface of the launch box body 11. The top of the launch box 171 is provided with a launch hole 1713 corresponding to the launch tube 174, and the bottom of the launch box 171 is provided with an air supply hole 1714 corresponding to the launch hole 1713, and the diameter of the air supply hole 1714 is smaller than the diameter of the specimen tube body. The air supply hole 1714 is connected to the air compressor 5 through a pipeline, and the air compressor 5 provides compressed air to it.

[0043] The driving nozzle 173 at one end of the launch box 171 away from the material guide cylinder 165 is controlled to open, and compressed air is sent into the launch box 171 to push the reversing block 172 to move in the direction close to the material guide cylinder 165. When it moves to the fixed groove 1721 and is aligned with the drop opening 1711, the specimen tube in the material guide cylinder 165 falls into the fixed groove 1721. At this time, the driving nozzle 173 away from the material guide cylinder 165 is closed, and the driving nozzle 173 close to the material guide cylinder 165 is opened. The compressed air sent in pushes the reversing block 172 to move in the direction close to the launch tube 174. When it moves to the fixed groove 1721 and is aligned with the launch hole 1713 and the air supply hole 1714, compressed air is sent into the pipeline below the air supply hole 1714 to blow the specimen tube into the launch tube 174 with the tube cap in front. At this time, the reversal of the specimen tube is completed, so that it is adjusted to the posture with the tube cap in front.

[0044] The implementation principle of Example 1 of the present application is as follows: the specimen tube is put into the feeding box 12 from the feeding port 111 and slides to the bottom of the material sorting mechanism 14. The material sorting mechanism 14 adjusts its posture to make it horizontal, and lifts the specimen tubes one by one to the top fixed plate 141. The specimen tube slides along the inclined top surface of the fixed plate 141 to between the two material guide rollers 154. At this time, the infrared detector 156 recognizes the specimen tube and controls the material turning motor 155 to start. The material turning motor 155 drives a material guide roller 154 to rotate through a belt, and the material guide roller 154 drives the specimen tube to turn over. During the rotation process, when the barcode on the specimen tube is aligned with the barcode scanner 153 below, the barcode scanner 153 scans it to record the information of the specimen tube.

[0045] After the specimen tube is scanned on the guide roller 154, the telescopic shaft of the adjustment cylinder 161 extends to drive the bottom of the push rod 162 to rotate downward, thereby driving the top of the push rod 162 to rotate in the direction close to the adjustment box 164. The push rod 162 drives the slider 1661 to move from the starting position to the direction close to the adjustment box 164 through the slide bar 1662, thereby driving the push block 163 to push the specimen tube to the adjustment box 164. Since the width of the adjustment slot 1641 is not less than the diameter of the specimen tube body but less than the diameter of the tube cap, no matter whether the specimen tube enters the adjustment slot 1641 with the tube body in front or the tube cap in front, the tube body of the specimen tube will pass through the adjustment slot 1641, and the tube cap will be stuck on the top of the adjustment slot 1641. At this time, the posture of the specimen tube is unified, that is, the posture of the tube cap is on top. At this time, the slider 1661 continues to push the specimen tube, and the specimen tube slides vertically from the opening at the tail of the adjustment slot 1641.

[0046] The driving nozzle 173 at one end of the launch box 171 away from the material guide cylinder 165 is controlled to open, and compressed air is sent into the launch box 171 to push the reversing block 172 to move in the direction close to the material guide cylinder 165. When it moves to the fixed groove 1721 and is aligned with the drop opening 1711, the specimen tube in the material guide cylinder 165 falls into the fixed groove 1721. At this time, the driving nozzle 173 away from the material guide cylinder 165 is closed, and the driving nozzle 173 close to the material guide cylinder 165 is opened. The compressed air sent in pushes the reversing block 172 to move in the direction close to the launch tube 174. When it moves to the fixed groove 1721 and is aligned with the launch hole 1713 and the air supply hole 1714, compressed air is sent into the pipeline below the air supply hole 1714 to blow the specimen tube into the launch tube 174 with the tube cap in front. At this time, the reversal of the specimen tube is completed, so that it is adjusted to the posture with the tube cap in front. Example 2

[0047] Example 2 of the present application discloses a pneumatic transmission system using a medical specimen pneumatic launching device.

[0048] Reference Figure 7A pneumatic transmission system using a medical specimen pneumatic transmitting device includes a specimen transmitting device 1, a specimen receiving device 2, a transmission pipeline 3 and an air compressor 5. The specimen tube is put into the specimen transmitting device 1 and transmitted to the specimen receiving device 2 through the transmission pipeline 3. During this process, the air compressor 5 provides compressed air for the entire system. When the specimen tube arrives in the specimen receiving device 2, the inspector can directly take out the specimen tube for inspection; or connect the specimen receiving device 2 to the existing specimen automatic processing equipment in the hospital. After the specimen tube arrives, it can directly enter the next level processing equipment without manual intervention, realizing the automatic and integrated transmission and processing of specimens, and improving medical efficiency.

[0049] The launching tube 174 of the specimen launching device 1 is connected to the transmission pipeline 3. The specimen tube enters the transmission pipeline 3 through the launching tube 174 and is transmitted with the tube cap in front, thereby ensuring the stability of the connection between the tube cap and the tube body and improving the safety of specimen transmission. At the same time, since the specimen tubes have a consistent posture in the transmission pipeline 3 with the tube cap in front, the stability of the air pressure in the transmission pipeline 3 is ensured, thereby improving the stability of specimen transmission.

[0050] Reference Figure 8 , Fig. 9 and Fig.10 The specimen receiving device 2 includes a receiving box 21, a touch screen is provided on the top of the receiving box 21, a material taking port 211 is provided on the front of the receiving box 21, a material taking door 212 is hinged at the material taking port 211, and a receiving bin 22 is provided in the receiving box 21 for receiving specimen tubes. A receiving tube 23 is connected to the top of the receiving box 21 by bolts, a buffer tube 24 is connected to the bottom of the receiving tube 23, the buffer tube 24 is connected to the air compressor 5 through a pipeline, and the bottom of the buffer tube 24 is connected to the receiving bin 22 through a guide tube 25. After the specimen tube comes out of the specimen transmitting device 1, it is transmitted to the receiving tube 23 through the transmission pipeline 3. At this time, the air compressor 5 sends compressed air into the receiving tube 23 through the buffer tube 24, which acts as a buffer for the fallen specimen tube, so as to reduce the speed of the specimen tube falling, so that the specimen tube slowly enters the guide tube 25, and finally falls into the receiving bin 22, and the material taking door 212 is opened to take out the specimen tube. In addition, in order to identify whether the specimen tube has arrived and facilitate the counting of the specimen tubes, a group of infrared sensors 26 is installed at the bottom end of the receiving tube 23. One group includes two infrared sensors 26. The two infrared sensors 26 are symmetrically arranged in the plane where the axis of the receiving tube 23 is located, and jointly identify and count the fallen specimen tubes. Example 3

[0051] The difference from Example 2 is that, referring to Fig.11 , Fig.12 and Fig.13, there are multiple transmission pipelines 3, that is, there are the following three situations: first, multiple specimen receiving devices 2 are set in the same system; second, multiple specimen transmitting devices 1 are set in the same system; third, multiple specimen transmitting devices 1 and multiple specimen receiving devices 2 are set in the same system. For multiple transmission pipelines 3, the system is also provided with a converter 4, which includes a sending converter 41 and a receiving converter 42 for switching different transmission paths.

[0052] There are three specific situations: First, refer to Fig.11 , a specimen transmitting device 1 and multiple specimen receiving devices 2 are arranged in the same system. At this time, the system selects a receiving converter 42, which is used to divide the transmission path into two, that is, the specimen tube emitted from the specimen transmitting device 1 is transported to the first receiving converter 42 through the transmission pipeline 3. At this time, it is divided by the receiving converter 42 and transmitted to two transmission pipelines 3 respectively, one of which is transported to the first specimen receiving device 2, and the other continues to be transported and transmitted to the second receiving converter 42. Then, it is divided by the second receiving converter 42 and divided into two transmission paths, one to the second specimen receiving device 2 and the other to the third receiving converter 42... and so on, it is switched continuously until it is transported to the specimen receiving device 2 to be delivered. The number of receiving converters 42 can be determined according to the number of specimen receiving devices 2, and the number of receiving converters 42 is always one less than the number of specimen receiving devices 2.

[0053] Second, refer to Fig.12 , a specimen receiving device 2 and multiple specimen transmitting devices 1 are arranged in the same system. In this case, the system uses a transmitting converter 41, which is used to combine the transmission paths into one, that is, the specimen tubes emitted from the first and second specimen transmitting devices 1 enter two different transmission pipelines 3 respectively, and the two transmission pipelines 3 are connected to the first transmitting converter 41. The specimen tubes transported by the two transmission pipelines 3 are collected together through the first transmitting converter 41 and output from the same transmission pipeline 3, and then enter the second transmitting converter 41, and the specimen tubes emitted by the third specimen transmitting device 1 are also transported to the second transmitting converter 41 through the transmission pipeline 3, and the second transmitting converter 41 collects and transports them to the third transmitting converter 41... and so on, until the specimen tubes emitted by all specimen transmitting devices 1 are transported to the specimen receiving device 2. The number of transmitting converters 41 can be determined according to the number of specimen transmitting devices 1, and the number of transmitting converters 41 is always one less than the number of specimen transmitting devices 1.

[0054] Third, refer to Fig.13In the same system, multiple specimen transmitting devices 1 and multiple specimen receiving devices 2 are arranged. At this time, the system selects a transmitting converter 41 and a receiving converter 42. The transmission paths of the multiple specimen transmitting devices 1 are gradually aggregated into the last transmitting converter 41 through the transmitting converter 41, and then gradually diverted through multiple receiving converters 42, so as to transport the specimens to the corresponding specimen receiving devices 2.

[0055] During the transmission of the specimen, only one specimen transmitting device 1 is allowed to be in operation at the same time, while the other specimen transmitting devices 1 are in a waiting state, so as to ensure the stable operation of the transmission system and the orderly transmission of the specimen. In addition, the selection of the transmission path is determined according to the specimen receiving device 2 to be transported. The barcode scanner 153 is electrically connected to the switching cylinder 414 of the receiving converter 42, which is used to control the switching block 416 to connect different transmission paths. After the barcode scanner 153 scans the barcode on the specimen tube in real time, the information of the specimen tube is synchronously uploaded to the system, and then compared with the specimen category built into the system or provided by the hospital HIS system, so as to complete the identification of the specimen tube category, and automatically determine the specimen receiving device 2 that needs to be reached according to different categories, and automatically select the middle transmission path based on this, and then transport it according to the selected transmission path, and finally transport it to the corresponding specimen receiving device 2 for specimen inspection.

[0056] Reference Fig.14 The transmission converter 41 includes a box body 411, in which a switching cylinder 414, a guide box 415 and a switching block 416 are arranged. Two feed holes 412 are opened at one end of the box body 411, and a discharge hole 413 is opened at the other end. The guide box 415 is fixedly connected to the box body 411, and both ends of the guide box 415 are corresponding to the feed hole 412 and the discharge hole 413 of the box body 411 and are connected through a pipeline. The switching block 416 is slidably connected to the guide box 415, and the switching cylinder 414 is used to drive the switching block 416 to slide. Two connecting channels 417 are opened in the switching block 416, which are used to connect the discharge hole 413 with the two feed holes 412, so as to complete the collection of specimen tubes transmitted by the two transmission channels.

[0057] Reference Fig.11 and Fig.14 The structure of the receiving converter 42 is similar to that of the transmitting converter 41 and will not be described in detail here. The only difference is that the feeding hole 412 of the receiving converter 42 is set to one and the discharging hole 413 is set to two. According to the setting of the system transmission path, the switching block 416 slides to switch different connecting channels 417 to complete the transportation of different types of specimen tubes and transmit them to the corresponding specimen receiving device 2. Example 4

[0058] The difference from Example 2 is that, referring to Fig.15 The infrared sensors 26 in the receiving tube 23 of the specimen receiving device 2 are arranged in three groups, the first group is located at the bottom of the receiving tube 23, the second group is located above the first group, and the interval between the second group and the first group is the length of a single specimen tube, and the third group is located above the second group, and the interval between the third group and the second group is less than the length of a single specimen tube. The three groups of infrared sensors 26 are arranged to accurately identify the number of specimen tubes that have arrived, and avoid the situation where multiple specimen tubes are mistakenly identified as one specimen tube due to the end-to-end contact of multiple specimen tubes.

[0059] The specific judgment is as follows: when the first and second groups of infrared sensors 26 recognize signals at the same time, and the third group of infrared sensors 26 does not recognize signals, the system recognizes that one specimen tube has arrived; when the three groups of infrared sensors 26 recognize signals at the same time, the system will make judgments according to the following logics: within the first unit time range, the three groups of infrared sensors 26 are triggered and disappear at the same time, and the system recognizes that two specimen tubes have arrived; within the first unit time range, the three groups of infrared sensors 26 are triggered and do not disappear at the same time, and the system recognizes that three specimen tubes have arrived; within the second unit time range, the three groups of infrared sensors 26 are triggered and disappear at the same time, and the system recognizes that four specimen tubes have arrived; within the second unit time range, the three groups of infrared sensors 26 are triggered and do not disappear at the same time, and the system recognizes that five specimen tubes have arrived... The system can set the length of the unit time according to the number of specimen tubes continuously emitted by the specimen emitting device 1, and increase the number of unit times used for judgment, so as to more accurately judge the number of specimen tubes arriving at the specimen receiving device 2, avoid misjudgment due to the end-to-end contact of the specimen tubes, and ensure the stable operation of the transmission system.

[0060] In this embodiment, the pneumatic transmission system is set to send a maximum of five specimen tubes continuously. After the first group of infrared sensors 26 recognizes the first specimen tube, the specimen transmitting device 1 will start sending the sixth specimen tube. Therefore, when the specimen tubes arrive in succession at the specimen receiving device 2, there are at most five specimen tubes. At this time, only two different judgment conditions of unit time need to be set.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
