Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary devices, specifically a reagent graded transfer device. Background Technology

[0002] In the medical industry, hospitals draw blood from a large number of patients daily for testing, typically using vacuum test tubes. These test tubes need to be transported promptly to the testing instruments in the laboratory. Early methods involved manual transport, which suffered from problems such as delayed delivery, susceptibility to errors, and potential environmental pollution and biological hazards. To address these issues, automated mechanical transport systems were developed. These systems typically traverse walkways and different floors, hence the design for aerial transport. Upon arrival at their destination, the test tubes fall from the air into a tabletop collection basket or other equipment. Through a transport module, they can interface with blood collection tables, pneumatic equipment, sorting equipment, and pre-sorting devices to transfer the test tubes to the material hopper of a corrugated iron machine, achieving sequential and prioritized transport.

[0003] In existing technologies, test tubes are often poured directly into the hopper or slid into the hopper by gravity using the height difference. During peak periods, blockages are prone to occur during transport, and test tubes may become stuck and unable to slide down. Furthermore, multiple specimens from outpatient and emergency departments are poured directly without a specific order, which can cause hemolysis during agitation in the conveyor belt, affecting test results. In addition, during the pre-sorting stage, specimens from different departments such as outpatient, emergency, and pneumatic conveyors cannot be prioritized, making it difficult to meet priority transport requirements and causing numerous inconveniences for test tube transport and subsequent testing. Utility Model Content

[0004] The purpose of this invention is to provide a reagent graded transfer device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reagent grading and transfer device, including a hopper frame, the hopper frame having two emergency tilting troughs on the left and right, each emergency tilting trough having two pre-sorting access holes on the hopper frame at its rear side, the hopper frame having two blood collection access holes on the left and right, and the hopper frame being fixedly connected to two conveying devices on the left and right, each conveying device having a pneumatic access pipe on its upper side, and the hopper frame being fixedly connected to a feeding device located between the two conveying devices. The conveying device transports test tubes input from the pre-sorting access holes, the blood collection access holes, the pneumatic access pipes, and the emergency tilting troughs to the feeding device for discharge. Multiple sensors are used to achieve different priorities, thereby enabling the orderly centralized processing of test tubes input from different locations and their sequential transport according to different priorities. Preferably, the conveying device includes two bases fixedly connected to the hopper frame. Each base is fixedly connected to two first side plates and two second side plates symmetrically connected front and rear. Rotating shafts are rotatably connected between the two second side plates and between the two first side plates. A conveyor belt is provided between the two rotating shafts. A driving tooth is rotatably connected to one of the first side plates corresponding to each base. A driven tooth is fixedly connected to each rotating shaft. The driven tooth meshes with the driving tooth. A motor is fixedly connected to the base. The motor is poweredly connected to the driving tooth. The motor can drive the conveyor belt to rotate. Blood tubes can enter the conveyor belt from the blood collection inlet, the pre-sorting inlet, the pneumatic inlet pipe, and the emergency pouring trough, thereby conveying the tubes input from both sides. Preferably, each of the bases has a first side plate fixedly connected to a connecting frame, and a light curtain sensor fixedly connected to the lower end face of the connecting frame. The first side plate has a second detection hole horizontally aligned with the light curtain sensor. The hopper frame has a first detection hole aligned with the second detection hole. The hopper frame is fixedly connected to two first connecting plates, and each first connecting plate is fixedly connected to a second sensor. The hopper frame is also fixedly connected to two first sensors located at the emergency pouring trough. Through the light curtain sensor, the first sensor and the second sensor sense blood tubes entering in different ways. By controlling the start and stop of the rotation of the conveyor belts on both sides, blood tubes with higher priority are transported first, and the order is distinguished. Preferably, the first side plate and the second side plate are fixedly connected to the base by bolts, allowing for convenient disassembly and maintenance; Preferably, each of the first side plates is fixedly connected to a mounting bracket, which, together with the mounting bracket, fixes the hopper frame to a suitable position in the blood tube transfer process; Preferably, the first side plate is fixedly connected to a protective cover by bolts, and the protective cover covers the driving tooth and the driven tooth to provide protection.

[0006] Preferably, the feeding device includes a conveyor frame fixedly connected to the middle of the hopper frame. The conveyor frame has two inlet holes and communicates with the hopper frame through the inlet holes. A washboard driver is fixedly connected to the front end of the conveyor frame. The washboard driver is powered by a washboard machine, which includes multiple fixed washboards and multiple movable washboards that move up and down synchronously. A guide plate located above the washboard driver is fixedly connected to the front end of the conveyor frame. The washboard driver drives the movable washboards to move up and down, agitating the blood tubes in the conveyor frame and orderly moving the blood tubes to the guide plate before they slide down to connect to the subsequent conveying device for transport. This avoids the problem of tube blockage during peak periods, where the tubes may get stuck and unable to slide down. It also prevents hemolysis during agitation in the washboard machine, thus avoiding affecting the test results. Preferably, the conveyor frame is fixedly connected to a second connecting plate, and the second connecting plate is fixedly connected to a third sensor. The third sensor monitors the number of blood tubes in the hopper frame, thereby controlling the speed at which blood tubes are input into the conveyor frame and the speed at which blood tubes are conveyed out by the washboard machine, to prevent blood tubes from clogging the conveyor frame. Preferably, the vertical position of the third sensor on the second connecting plate can be adjusted, thereby adjusting the detection accuracy of the test tubes in the hopper frame and the conveyor frame, and triggering the sensor when the number of test tubes is different.

[0007] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a hopper frame, pneumatic inlet pipe, and conveyor belt. Blood tubes from different blood collection locations are separately transported to the hopper frame via blood collection inlet, emergency tilting trough, pre-sorting inlet, and pneumatic inlet pipe. A light curtain sensor, a third sensor, a first sensor, and a second sensor monitor the tube positions and adjust the transport priority of tubes under different operating modes. When a high-priority blood tube enters the hopper frame, the transport of low-priority blood tubes is paused, and high-priority blood tubes are transported first. This allows for priority transport of blood tubes from the emergency department, distinguishing between them.

[0008] This invention incorporates a movable washboard, a fixed washboard, and a conveyor frame. After blood tubes are inserted into the conveyor frame, a washboard driver moves the movable washboard up and down while the fixed washboard remains stationary. Both the movable and fixed washboards are tilted, allowing the blood tubes piled up in the conveyor frame to be conveyed one by one to the guide plate and slide down. This prioritizes the blood tubes and ensures orderly delivery, preventing tube blockages during peak periods and avoiding the problem of tubes getting stuck and unable to slide down. It also prevents hemolysis caused by agitation within the washboard machine, thus avoiding any impact on test results. Attached Figure Description

Each base 114 is fixedly connected to two symmetrically arranged first side plates 109 and two symmetrically arranged second side plates 113. Rotating shafts 120 are rotatably connected between the two second side plates 113 and between the two first side plates 109. A conveyor belt 125 is provided between the two rotating shafts 120. A drive gear 118 is rotatably connected to one of the first side plates 109 corresponding to each base 114. Each component is fixedly connected with a driven tooth 119, which meshes with the driving tooth 118. A motor 108 is fixedly connected to the base 114, and the motor 108 is poweredly connected to the driving tooth 118. The motor 108 can drive the conveyor belt 125 to rotate, and the blood tube 111 can enter the conveyor belt 125 from the blood collection inlet 102, the pre-sorting inlet 103, the pneumatic inlet pipe 104, and the emergency pouring trough 105, thereby enabling the transport of tubes input from both sides. Each of the bases 114 has a first side plate 109 fixedly connected to a connecting frame 115. A light curtain sensor 116 is fixedly connected to the lower end face of the connecting frame 115.

[0014] Example 2:

[0015] Please see Figure 1-7 In order to transport the separated blood test tubes in an orderly manner and to prevent hemolysis during agitation in the washboard machine, a conveyor frame 101, a fixed washboard 130, and a movable washboard 129 are provided. The feeding device 132 includes a conveyor frame 101 fixedly connected to the middle of the hopper frame 100. The conveyor frame 101 has two inlet holes 126, and the conveyor frame 101 communicates with the hopper frame 100 through the inlet holes 126. A washboard driver 128 is fixedly connected to the front end face of the conveyor frame 101. The washboard driver 128 is poweredly connected to a washboard machine. The washboard machine includes multiple fixed washboards 130 that are stationary and multiple movable washboards 129 that move synchronously up and down. The front end face of the conveyor frame 101 is fixedly connected to... The guide plate 127 located on the upper side of the washboard driver 128 drives the movable washboard 129 to move up and down, thereby agitating the blood test tubes 111 in the conveyor frame 101. The blood test tubes 111 are then orderly moved up to the guide plate 127 and slide down to connect to the subsequent conveying device for transport. This avoids the problem of tube blockage during peak periods, where the test tubes may get stuck at a certain point and be unable to slide down. It also prevents hemolysis from occurring during agitation in the washboard machine, thus avoiding affecting the test results. The conveyor frame 101 is fixedly connected to a second connecting plate 124, and the second connecting plate 124 is fixedly connected to a third sensor 122. The third sensor 122 monitors the number of blood tubes in the hopper frame 100, thereby controlling the speed at which blood tubes are input into the conveyor frame 101 and the speed at which blood tubes are conveyed out by the washboard machine, so as to prevent blood tubes from clogging the conveyor frame 101. The vertical position of the third sensor 122 on the second connecting plate 124 can be adjusted, thereby adjusting the detection accuracy of the test tubes in the hopper frame 100 and the conveyor frame 101, and triggering the sensor when the number of test tubes is different.

[0016] Working principle: During installation, the hopper frame 100 is installed at a suitable position below the pneumatic inlet pipe 104 using the mounting bracket 107 to collect and transfer blood test tubes 111.

[0017] Operating Mode 1: Without priority, blood tubes 111 enter the hopper rack 100 from the blood collection table clinic through the left blood collection inlet 102. The light curtain sensor 116 detects the blood tube 111, automatically starting the motor 108. The motor 108 drives the active gear 118 to rotate, which in turn drives the driven gear 119 to rotate. The driven gear 119 then drives the rotating shaft 120 to rotate, which in turn drives the conveyor belt 125 to rotate, transporting the specimen from left to right to the conveyor rack 101. At this time, emergency tubes are poured into the left emergency pouring trough 105, and the mixed tubes are transported together by the conveyor belt. If priority is required, then emergency blood tubes 111 need to be poured into the right emergency pouring trough 105. The sensor on the right hopper rack 100 detects the tubes and determines that a tube has fallen onto the right conveyor belt. When a blood tube 111 is detected being poured in, the left conveyor belt module pauses transmission according to the program settings. The right conveyor belt then transfers the higher-priority blood tubes 111 into the conveyor rack 101. The washboard driver 128 is then activated, moving the movable washboard 129 up and down to transport the blood tubes 111. After the washboard machine has transported all the blood tubes 111, the left conveyor belt 125 restarts. When a certain number of tubes are in the washboard machine hopper, the third sensor 122 detects tubes. If there are blood tubes 111 on the right side, the right conveyor belt stops transmission. The right conveyor belt restarts when the conveyor rack 101 is emptied until the third sensor 122 can no longer detect tubes. This allows for the priority transmission of blood tubes 111. Combined with the agitation of the blood tubes 111 within the conveyor rack 101, the possibility of hemolysis is reduced. Furthermore, the vertical position of the third sensor 122 can be adjusted based on the number of tubes stored in the conveyor rack 101.

[0018] Operating Mode 2: When no priority is assigned, when a pre-sorting device is connected, blood tubes 111 are connected through the left pre-sorting access port 103, and blood tubes 111 connected through the blood collection access port 102 are simultaneously conveyed away from the conveyor rack 101. If priority is assigned, pre-sorted blood tubes 111 are connected through the right pre-sorting access port 103. Once a certain number of tubes are reached, the second sensor 121 detects the tubes, the right conveyor belt starts, and the left conveyor belt stops.

[0019] Operating mode 3: When there is no priority, when a pneumatic device is connected, it falls from the air inlet of the left pneumatic access pipe 104 onto the left conveyor belt 125. It can be transported away from the conveyor rack 101 at the same time as the blood test tube 111 connected to the blood collection access hole 102. If priority is required, the blood test tube 111 connected to the pneumatic access pipe 104 falls from the right pneumatic access pipe 104 onto the right conveyor belt 125. After the number of test tubes reaches a certain number, the second sensor 121 detects the test tubes, the right conveyor belt starts, and the left conveyor belt stops.

[0020] Operating Mode 4: When no priority is assigned, blood tubes 111 are simultaneously introduced into the hopper rack 100 via the pneumatic inlet pipe 104, pre-sorting inlet hole 103, and emergency pouring trough 105. They can then be simultaneously transported together with blood tubes 111 introduced through the blood collection inlet hole 102 via the left conveyor belt 125 to the conveyor rack 101 and transported away by a washboard machine. If priority is required, blood tubes 111 must be sequentially introduced from the pre-sorting inlet hole 103, pneumatic inlet pipe 104, and emergency pouring trough 105 onto the right conveyor belt 125. Once a certain number of tubes are received, the second sensor 121 detects the tubes, the right conveyor belt starts, and the left conveyor belt stops.

[0021] The workflow can be adjusted according to the hospital's actual situation, with reasonable allocation of priorities. Various combinations are available; blood collection tubes can also be entered from the right side, operating symmetrically with the above workflow, requiring no changes to equipment placement. The program can be modified accordingly based on the hospital's needs.
