[0079] The invention discloses a medical liquid filling device, which is used for automatically filling quantitative liquid into a plurality of test tubes and sealing the tubes, so as to improve the filling efficiency and safety.

[0080] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0081] In the following, the terms "first", "second", and "third" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0082] Combination Figure 1-Figure 24 The medical liquid filling device disclosed in the present invention comprises a support assembly 100, a filling mechanism 200, a capping mechanism 300 and a rotating mechanism 400. The support assembly 100 plays a supporting role. The filling mechanism 200, the capping mechanism 300 and the rotating mechanism 400 are all arranged on the support assembly 100. The filling mechanism 200 is used to fill a quantitative amount of medical liquid into a test tube 600 located at a filling station. The capping mechanism 300 is used to screw a bottle cap 700 on the test tube 600 located at the capping station to seal the test tube 600. A test tube rack 500 is arranged on the rotating mechanism 400. The test tube rack 500 is provided with a plurality of test tube slots 501 for placing the test tube 600. The rotating mechanism 400 is used to drive the test tube rack 500 to rotate, so that each test tube 600 placed on the test tube rack 500 can be rotated to the filling station and the capping station in sequence.

[0083] In a specific implementation process, after the test tube 600 is placed on the test tube rack 500, the test tube rack 500 and the test tube 600 are placed together on the rotating mechanism 400, and the rotating mechanism 400 drives the test tube rack 500 and the test tube 600 to rotate together. During the rotation process, each test tube 600 is rotated to the filling station and the capping station in sequence. At the filling station, the filling mechanism 200 fills a quantitative amount of medical liquid into the test tube 600, and at the capping station, the capping mechanism 300 screws the bottle cap 700 to the filled test tube 600. After the rotating mechanism 400 controls the test tube rack 500 to rotate one circle, it can be ensured that each test tube 600 on the test tube rack 500 completes the quantitative liquid filling and capping.

[0084] Compared with the prior art, the medical liquid filling device disclosed in the present invention is small in size and can perform quantitative liquid filling and capping operations of test tubes 600 in batches. The filling process is intelligent, convenient, reliable and efficient. At the same time, since the bottle cap 700 of the test tube 600 is automatically tightened after the filling is completed, the safety of subsequent operations by medical staff is improved.

[0085] The support assembly 100 may be specifically formed by splicing a plurality of metal plates or plastic plates, and the specific structure of the support assembly 100 may be adjusted according to the specific structure and arrangement position of the filling mechanism 200 , the capping mechanism 300 and the rotating mechanism 400 .

[0086] The capping mechanism 300 is used to store a certain amount of bottle caps 700. During the capping process, after the capping mechanism 300 drives the bottle cap 700 to move down to the test tube 600 located at the capping station, the capping mechanism 300 drives the bottle cap 700 to rotate to complete the capping process; or, during the process of the capping mechanism 300 driving the bottle cap 700 to move down, the capping mechanism 300 is always in a state of driving the bottle cap 700 to rotate until the bottle cap 700 is screwed onto the test tube 600. For ease of description, the direction in which the capping mechanism 300 drives the bottle cap 700 to rise and fall is taken as the vertical direction, and the initial position of the bottle cap 700 on the capping mechanism 300 is taken as the upper side, and the position when the capping mechanism 300 drives the bottle cap 700 to approach the capping station is taken as the lower side.

[0087] In a specific embodiment of the present invention, the capping mechanism 300 includes a lifting frame, a screwing spindle 310, a bottle cap clip 320, a screwing assembly and a lifting assembly 340. The screwing spindle 310 is rotatably arranged on the lifting frame, and a screwing groove is provided along the axial direction. The top area of ​​the screwing groove is used as an assembly area, and the bottom area is used as a screwing area for storing a bottle cap 700. The bottle cap clip 320 is provided with a bottle cap storage tank that can store multiple bottle caps 700. The bottle cap clip 320 is detachably arranged in the assembly area, which is used to continuously transport bottle caps 700 to the screwing area to ensure the continuous supply of bottle caps 700, and to press down the bottle cap 700 during the screwing process of the bottle cap 700 to ensure that the bottle cap 700 can be buckled on the test tube 600. The screwing assembly is arranged on the lifting frame and is in transmission connection with the screwing spindle 310, and is used to drive the screwing spindle 310 to rotate, thereby driving the bottle cap 700 to rotate. The lifting assembly 340 is disposed on the support assembly 100 and is used to drive the lifting frame to move up and down along the axial direction of the screwing spindle 310 between the initial position and the capping position.

[0088] After the bottle cap clip 320 is assembled to the assembly area of ​​the screwing spindle 310, a bottle cap 700 in the bottle cap storage tank enters the screwing area. After the test tube 600 moves to the screwing station, the lifting assembly 340 drives the screwing spindle 310 and the bottle cap clip 320 to descend to the top of the test tube 600, and the bottle cap 700 in the screwing area is buckled on the test tube 600, the screwing spindle 310 stops descending, and the screwing assembly drives the screwing spindle 310 to drive the bottle cap 700 to rotate, and the bottle cap clip 320 provides a downward pressure force to the bottle cap 700. Under the joint action of the screwing spindle 310 and the bottle cap clip 320, the bottle cap 700 spirally rotates downward until it is tightened on the test tube 600, completing the tightening process of the bottle cap 700. Finally, under the action of the lifting assembly 340, the screwing spindle 310 is reset, and when the screwing spindle 310 rises and is gradually separated from the test tube 600, the bottle cap clip 320 pushes the next bottle cap 700 into the screwing area.

[0089] Those skilled in the art will appreciate that the above-mentioned bottle cap storage tank can usually store a plurality of bottle caps 700, preferably the same number as the test tube slots 501 on a test tube rack 500, so that the bottle cap clips 320 can be replaced while replacing the test tube rack 500 to ensure the production rhythm.

[0090] In order to facilitate the replacement of the bottle cap clip 320, the bottle cap clip 320 is detachably fixed to the screw spindle 310 by means of a buckle, a twist buckle, etc. Fig. 9 and Fig.19 In one embodiment, at least two fixing buckles 323 are rotatably provided on the top of the bottle cap clip 320, and a mounting boss for the fixing buckles 323 to be engaged is provided on the top of the screwing spindle 310. After the bottle cap clip 320 is installed in the assembly area, the fixing buckle 323 located on the top of the bottle cap clip 320 can be flipped and engaged to the mounting boss to achieve the buckling and fixation of the screwing spindle 310 and the bottle cap clip 320.

[0091] Specifically, combined Figure 5 and Fig.19 The fixing buckle 323 is fixed to the bottle cap clip 320 through a pin shaft, and a thrust spring is used to provide a force for the fixing buckle 323 to be securely fastened to the mounting boss of the screwing spindle 310 .

[0092] When the bottle cap clip 320 is not assembled to the screwing spindle 310, it is necessary to ensure that the bottle caps 700 do not fall out of the bottle cap storage slot. When the bottle cap clip 320 is assembled to the screwing spindle 310, it is necessary to enable the bottle caps 700 to automatically fall from the bottle cap storage slot to the screwing area and ensure a continuous supply of bottle caps 700 in the screwing area.

[0093] In a specific embodiment disclosed in the present invention, a first buckle 322 is rotatably provided on the bottle cap clip 320 via a first elastic member, and a first pushing slope is provided on the screwing spindle 310 for pushing the first buckle 322 from an initial state to an open state; when the first buckle 322 is in the initial state, the first buckle 322 is located at the outlet of the bottle cap storage tank at the lower limit of the action of the first elastic member, and when the first buckle 322 is in the open state under the action of the first pushing slope to overcome the action force of the first elastic member, the first buckle 322 rotates to a position avoiding the outlet of the bottle cap storage tank, so that the bottle cap 700 in the bottle cap storage tank can freely fall downward to the screwing area.

[0094] Specifically, combined Fig.11, the first buckle 322 can be turned over in the direction of the screwing area at the bottom of the bottle cap storage tank under the action of the first push inclined surface. The first buckle 322 can be fixed to the bottle cap clip 320 by a pin, and the first elastic member provides the force for the first buckle 322 to reset. According to the actual layout space, the first elastic member can be a torsion spring or a thrust spring. The first buckle 322 is usually evenly arranged around the circumference of the bottle cap storage tank to ensure reliable positioning of the bottle cap 700 in the bottle cap storage tank.

[0095] Combination Figure 19-21 The bottle cap clip 320 is composed of multiple components, including a clip body 321, a mounting plate 324, a thrust spring 325 and a top pressing sleeve 326. A bottle cap storage tank is axially penetrated inside the clip body 321, and the top pressing sleeve 326 is arranged in the bottle cap storage tank. The first buckle 322 is arranged at the first end of the clip body 321. The first end of the thrust spring 325 is connected to the mounting plate 324, and the other end extends into the top pressing sleeve 326, so that the top pressing sleeve 326 can provide a pressing force to the bottle cap 700 in the bottle cap storage tank. The mounting plate 324 is used to be connected to the second end of the screwing spindle 310, and the above-mentioned fixing buckle 323 is arranged on the mounting plate 324.

[0096] Those skilled in the art will appreciate that the thrust spring 325 mentioned above indirectly provides downward pressure to the bottle cap 700 via the top-pressing sleeve 326. In some embodiments, a weight may be directly used instead of the thrust spring 325 and the top-pressing sleeve 326 to provide downward pressure to the bottle cap 700. It is only necessary to ensure that the lighter bottle cap 700 can move smoothly down onto the test tube 600.

[0097] During the lifting and lowering of the screwing spindle 310 , the bottle cap 700 in the screwing area needs to be kept from falling off. After the rotation of the bottle cap 700 is completed, the bottle cap 700 in the screwing area needs to be able to escape from the screwing area and remain on the test tube 600 .

[0098] Combination Figure 11-13 In one embodiment, a second buckle 312 is rotatably provided on the screwing spindle 310 through a second elastic member, and a baffle 130 is provided on the support assembly 100. A second push slope for pushing the second buckle 312 from an initial state to an open state is provided on the baffle 130. When the lifting frame is in the initial position, the second buckle 312 is in the initial state, and the second buckle 312 is limited at the exit of the screwing area. When the lifting frame is in the capping position, the second buckle 312 is pushed from the initial state to the open state by the second push slope, and the second buckle 312 rotates to a position avoiding the exit of the screwing area, and the bottle cap 700 in the screwing area can freely fall onto the test tube 600 at the capping station.

[0099] When the screwing spindle 310 is in the initial position, the second buckle 312 has no contact with the second pushing inclined surface, the second buckle 312 is in the initial state, and the bottle cap 700 is limited in the screwing area; when the screwing spindle 310 is driven by the lifting assembly 340 to descend to the screwing station, the second buckle 312 is automatically flipped to the open state that does not affect the free fall of the bottle cap 700 under the action of the second pushing inclined surface, and the bottle cap 700 can partially fall on the test tube 600 at the screwing station. At this time, the screwing assembly drives the screwing spindle 310 to rotate, and drives the bottle cap 700 to rotate for screwing. After the screwing is completed, the screwing spindle 310 is driven by the lifting assembly 340 to move to the initial position, disengage from the bottle cap 700 that has been screwed. At the same time, the second buckle 312 is reset under the action of the second elastic member, and limits the next bottle cap 700 to be screwed in the screwing area, waiting for subsequent screwing.

[0100] Combination Fig.15 and Fig.16 The second buckle 312 is fixed on the screw spindle 310 through the pin 3122, and the second elastic member provides a resetting force. In combination with the actual layout space, the second elastic member can be a torsion spring or a thrust spring. Fig.16 A structural solution in which the second elastic member is a torsion spring 3121 is shown. The second buckles 312 are usually arranged uniformly around the circumference of the screwing area to ensure reliable positioning of the bottle cap 700 in the screwing area.

[0101] The screw spindle 310 is generally a split structure consisting of multiple parts to facilitate processing. Fig.10 The screwing spindle 310 includes a main body and a spindle head 311. The main body forms an assembly area, the spindle head 311 is arranged at the bottom end of the main body and forms a screwing area, and the second buckle 312 is arranged on the spindle head 311. The main body is transmission-connected with the screwing assembly, and can also be designed as an integrated structure or a split structure according to the actual structure.

[0102] In one embodiment, the screwing assembly includes a screwing motor 330, a first transmission gear 331, and a second transmission gear 332. The screwing motor 330 is disposed on the lifting frame, the first transmission gear 331 is in transmission connection with the screwing motor 330, and the second transmission gear 332 is coaxially fixed with the screwing spindle 310 and in transmission connection with the first transmission gear 331. When the screwing motor 330 rotates, the first transmission gear 331 and the second transmission gear 332 are sequentially driven, thereby driving the screwing spindle 310 and the bottle cap 700 in the screwing spindle 310 to rotate together.

[0103] Combination Fig. 9 , Fig.10 and Fig.17This structural form of transmission through the first transmission gear 331 and the second transmission gear 332 allows the second transmission gear 332 to be fixed in the middle position of the screwing spindle 310, and at the same time makes the screwing spindle 310 and the power output shaft of the screwing motor 330 staggered. Compared with the structural scheme in which the power output shaft of the screwing motor 330 is coaxially arranged with the screwing spindle 310 and directly connected by transmission, it can effectively reduce the extension height of the screwing component in the vertical direction and enhance the stability of the structure.

[0104] The screwing motor 330 has a stall protection function, and can identify the stall torque. When the screwing motor 330 is stalled, the screwing motor 330 is automatically powered off to prevent the screwing motor 330 from being damaged. With the help of the stall protection function of the screwing motor 330, the capping mechanism 300 can detect and identify the tightening state of the bottle cap 700. During the capping process, under the thrust of the thrust spring 325 of the bottle cap clip 320, the bottle cap 700 is automatically screwed into the test tube 600 along the thread until resistance appears and it cannot be screwed further, and the screwing motor 330 is stalled. After the control system of the medical liquid filling device collects the stall information of the screwing motor 330, it stops the rotation of the screwing motor 330 and releases the force of the screwing motor 330. The lifting frame drives the screwing spindle 310 to rise to the initial position as a whole, and the second buckle 312 rebounds to the initial state and limits the bottle cap 700 in the screwing area.

[0105] In addition, the screwing motor 330 may be configured to automatically stop rotating after driving the screwing spindle 310 and the bottle cap 700 to rotate a preset number of times, so as to prevent the screwing motor 330 from being blocked while ensuring that the bottle cap 700 and the test tube 600 are securely tightened.

[0106] The lifting assembly 340 may specifically be a motor fixedly disposed on the support assembly 100 , and the lifting frame is disposed at the output end of the motor to directly drive the lifting frame to move.

[0107] In one embodiment, the lifting assembly 340 includes a lifting motor, a lifting screw and a lifting nut. The lifting motor is arranged on the bracket assembly 100. The lifting screw is connected to the lifting motor through a coupling, and the extension direction of the lifting screw is parallel to the extension direction of the screwing spindle 310. The lifting nut is matched with the lifting screw and connected to the lifting frame. When the lifting motor is started, the lifting screw rotates and drives the lifting nut to move up and down. The lifting nut drives the lifting frame, the screwing assembly on the lifting frame, and the screwing spindle 310 to move up and down between the initial position and the screwing position.

[0108] In order to ensure the reliability of the lifting action of the lifting assembly 340, Fig.12 and Fig.18A lifting guide rail 110 is set on the bracket assembly 100, and the lifting slider 111 is connected to the screw spindle 310. The lifting guide rail 110 is arranged along the lifting direction of the lifting frame. As the lifting nut rises and falls or the motor push rod extends and retracts, the lifting slider 111 slides along the lifting guide rail 110 to guide the lifting action.

[0109] In one embodiment, in combination Fig.12 , a photoelectric sensor 121 is provided on the support assembly 100, and a trigger 120 is provided on the screwing spindle 310 or the lifting frame. When the lifting frame descends to the capping position, the trigger 120 blocks the laser beam of the photoelectric sensor 121 and triggers the photoelectric sensor 121. After the control system of the medical liquid filling device receives the signal that the photoelectric sensor 121 is triggered, the action of the lifting assembly 340 is stopped, and the screwing spindle 310 is limited to the capping position.

[0110] Furthermore, a label printing component 800 is provided on the lifting frame, and the label printing component 800 is used to print labels on the test tube 600 located at the capping station. Specifically, the label printing component 800 can be an ink cartridge. As the lifting frame descends or rises, the label printing component 800 synchronously performs the process of label printing on the test tube 600. Printing labels on the filled test tube 600 makes it easier for medical staff to operate in the future. Fig.13 and Fig.17 The label printing component 800 is connected to the lifting frame through a mounting bracket 810 and a mounting rod 820.

[0111] The lifting frame can be specifically formed by splicing a plurality of metal plates or plastic plates, and the specific structure of the lifting frame is adjusted according to the specific structure of the screwing assembly and the screwing spindle 310 .

[0112] In one embodiment, in combination Fig.13 , Fig.17 and Fig.18 , the cap screwing mechanism 300 is arranged on the bracket assembly 100 through the fixing plate 101, the lifting frame includes a first bearing seat 350 and a second bearing seat 353, the first bearing seat 350 is arranged parallel to the upper side of the second bearing seat 353, and the first bearing seat 350 and the second bearing seat 353 are connected through a connecting plate 354, and the lifting assembly 340 is connected to the connecting plate 354. The screwing spindle 310 is rotatably matched with the first bearing seat 350 through the first bearing 351, and is rotatably matched with the second bearing seat 353 through the second bearing 352, and the screwing motor 330 is arranged on the first bearing seat 350 through the fixing frame. The lifting slider 111 is fixed on the connecting plate 354, and the baffle 130, the lifting guide rail 110 and the lifting assembly 340 are all arranged on the fixing plate 101.

[0113] Combination Fig.23The test tube rack 500 is provided with a plurality of test tube slots 501 for holding the test tubes 600. In order to prevent the test tubes 600 from rotating when the bottle caps 700 are screwed, the test tubes 600 are provided with outer wall profiles, and the test tube slots 501 have fifth anti-rotation surfaces 505 for cooperating with the outer wall profiles to prevent the test tubes 600 from rotating. Exemplarily, the cross-section of the test tube slots 501 can be a polygon such as a quadrilateral or a hexagon, and correspondingly, the cross-sectional shape of the outer wall profile of the test tube 600 corresponds to the cross-sectional shape of the test tube slots 501.

[0114] In order to facilitate the screwing spindle 310 to drive the bottle cap 700 to rotate and realize the smooth transfer of the bottle cap 700 between the bottle cap storage tank and the screwing area, the cross section of the bottle cap 700 is a polygonal structure, and the side wall of the bottle cap 700 is provided with an outer wall profile. Fig. 22 The inner wall of the bottle cap storage tank of the bottle cap clip 320 (the inner wall 3201 of the clip) matches the shape of the bottle cap 700, and is provided with a plurality of third anti-transformation surfaces that correspond one-to-one with the outer wall profile of the bottle cap 700, and a plurality of fourth anti-transformation surfaces that correspond one-to-one with the outer wall profile of the bottle cap 700 are provided on the inner wall of the screwing area, and the positions of the third anti-transformation surfaces and the fourth anti-transformation surfaces correspond one-to-one, so that the bottle cap storage tank and the screwing area are aligned, and the bottle cap 700 can be directly dropped from the bottle cap storage tank into the screwing area without adjusting the angle.

[0115] A plurality of first anti-transformation surfaces are arranged on the outer wall 3202 of the bottle cap clip 320, and a plurality of second anti-transformation surfaces corresponding to the first anti-transformation surfaces are arranged on the inner wall of the assembly area. Through the cooperation of the second anti-transformation surfaces and the first anti-transformation surfaces, it is convenient for the screwing spindle 310 to drive the bottle cap clip 320 to rotate together, and ensure the alignment of the bottle cap storage tank and the screwing area.

[0116] The rotating mechanism 400 includes a tray 420 and a rotating motor 410. The tray 420 is rotatably disposed on the support assembly 100 and is provided with a receiving slot 422 for receiving the test tube rack 500. The rotating motor 410 is disposed on the support assembly 100 and is transmission-connected to the tray 420 for driving the tray 420 to rotate the test tube rack 500 so that each test tube slot 501 rotates to the filling station and the capping station in sequence during filling.

[0117] The specific structure of the rotating mechanism 400 can be adjusted according to the actual situation, and it is only necessary to ensure that the tray 420 can drive the test tube rack 500 to rotate. Figure 6 and Figure 7In the above embodiment, the tray 420 is arranged on the top of the rotating motor 410, and a three-dimensional spatial layout is adopted in which the tray 420 is directly connected to the power output shaft of the rotating motor 410, that is, the rotation axis of the tray 420 is coaxially arranged with the power output shaft of the rotating motor 410; in other embodiments, the rotation axis of the tray 420 is parallel to the power output shaft of the rotating motor 410 and is staggered, and the two are transmitted through a gear structure to realize a planar spatial layout.

[0118] Furthermore, in order to achieve safe filling of liquid and avoid the situation where the liquid is directly filled into the test tube rack 500 or the tray 420 when the test tube 600 is not placed in some test tube slots 501, a first sensor is provided on the support assembly 100. The first sensor is arranged toward the filling station and is used to detect whether there is a test tube 600 at the filling station, so as to judge whether the filling mechanism 200 currently needs to discharge liquid. The first sensor can be a distance sensor, an image sensor, a photoelectric sensor, etc. The first sensor can be specifically provided above the tray 420 to directly detect whether the test tube 600 is in place from the top position of the test tube rack 500. At this time, the detection path of the first sensor is perpendicular to the rotation plane of the test tube rack 500.

[0119] According to the specific detection principle of the first sensor, corresponding structures can be provided on the tray 420 and the test tube rack 500 to facilitate detection by the first sensor.

[0120] In some embodiments, the first sensor is an image sensor, and its detection path is parallel to the rotation plane of the test tube rack 500. Fig.23 A detection window 504 is provided on the side wall of each test tube slot 501 , and each detection window 504 is arranged on the outer peripheral wall of the test tube rack 500 . The first sensor can detect whether there is a test tube 600 at the filling station at the detection window 504 .

[0121] In some embodiments, the first sensor is a photoelectric sensor, and its detection principle is to first detect the light reflection amount of the background reference, and then detect the light reflection amount after the object to be detected is added, and calculate the difference between the two to determine whether the object to be detected exists.

[0122] Specifically, combined Fig.24A reference component 421 serving as a detection reference for the photoelectric sensor is provided on the tray 420. The reference component 421 may be a circular base column. The position on the circular base column corresponding to the photoelectric sensor is evenly painted black to serve as a calibration portion, and the calibration portion is circumferentially arranged around the reference component 421. A reference hole for embedding the reference component 421 is provided in the middle position of the test tube rack 500, and each test tube slot 501 is circumferentially arranged around the reference hole, and a detection window 504 is provided on the side wall of each test tube slot 501. Through the setting of the detection window 504, when there is no test tube 600 at the filling station, the detection aperture of the photoelectric sensor can pass through the test tube slot 501 through the detection window 504 to reach the calibration part and obtain a first light reflection amount; when there is a test tube 600 at the filling station, the detection aperture of the photoelectric sensor can pass through the detection window 504 and the test tube 600 to reach the calibration part and obtain a second light reflection amount, and whether there is a test tube 600 at the filling station is judged by the numerical difference between the first light reflection amount and the second light reflection amount.

[0123] Furthermore, combined with Fig.23 The test tube rack 500 is provided with an avoidance portion 503. Along the circumference of the test tube rack 500, each test tube slot 501 is arranged at intervals, and the avoidance portion 503 is arranged between two test tube slots 501. At the avoidance portion 503, the reference hole is connected to the outside. When the medical liquid filling device is in the initial state, the avoidance portion 503 is in the filling position, and each test tube slot 501 is not in the filling position. At this time, the detection aperture of the photoelectric sensor can be along Fig.23 The direction indicated by the middle arrow is directly irradiated from the avoidance portion 503 to the calibration portion of the reference component 421, and at the same time, the photoelectric sensor detects the first light reflection amount, and the filling mechanism 200 remains in a liquid-free state; when the rotating motor 410 controls the tray 420 to rotate one circle to complete the liquid filling and capping of all the test tubes 600 on the test tube rack 500, the avoidance portion 503 returns to the filling station, and at this time, the rotating motor 410 automatically stops, and at the same time, the photoelectric sensor detects the first light reflection amount, and the filling mechanism 200 remains in a liquid-free state.

[0124] Combination Fig.23 and Fig.24 By setting the avoidance portion 503, the test tube rack 500 has a non-rotationally symmetrical structure. At the same time, the shape of the containing groove 422 matches the bottom shape of the test tube rack 500. The avoidance portion 503 can be used as a mark to identify the rotation position of the tray 420, which is convenient for medical staff to judge the liquid filling progress of each test tube 600.

[0125] The test tube slots 501 are evenly arranged, and an angle encoder with an absolute value is provided inside the rotating motor 410 so that the rotation angle can be controlled by the angle encoder.

[0126] Furthermore, a second sensor is provided on the support assembly 100, and the second sensor is used to detect whether the test tube 600 is in place at the capping station. The specific structure and operation mechanism of the second sensor may be the same as those of the first sensor, which will not be described in detail herein; alternatively, only the first sensor is provided on the support assembly 100, and the second sensor is not provided, and the capping mechanism 300 can receive a signal indicating that filling is completed from the filling mechanism 200. When the first sensor detects that the test tube 600 has arrived at the filling station, the filling mechanism 200 discharges liquid. After the liquid discharge is completed, the filling mechanism 200 sends a signal to the capping mechanism 300. After receiving the signal, the capping mechanism 300 waits for a preset time for the rotating mechanism 400 to rotate the test tube 600 from the filling station to the capping station, and then automatically performs the capping action.

[0127] Combination Fig.23 In order to facilitate medical staff to take the test tube, a handle 502 is fixedly installed above the test tube rack 500.

[0128] The filling mechanism 200 includes a liquid storage tank 210 and a quantitative control component. The liquid storage tank 210 is arranged on the bracket component 100, and is used to hold a certain amount of medical liquid. The liquid outlet of the liquid storage tank 210 is connected to a liquid outlet pipeline 211, and the quantitative control component is arranged on the liquid outlet pipeline 211, and is used to control the liquid storage tank 210 to discharge liquid quantitatively.

[0129] In actual use, the liquid to be filled is first placed in the liquid storage tank 210, and the type of the liquid is not limited to liquid medicine, pure water, etc. Then the test tubes 600 that need to be filled with liquid are placed one by one in each test tube slot 501 of the test tube rack 500, and then the test tube rack 500 and the test tube 600 are placed on the rotating mechanism 400 together to complete the preparation work. The medical liquid filling device is started, and the rotating mechanism 400 drives the test tube rack 500 to rotate so that the first test tube 600 rotates to the filling station and then stops. At the same time, the filling mechanism 200 controls the liquid storage tank 210 to flow a preset amount of liquid to the filling station. After the first test tube 600 is filled, the filling mechanism 200 stops discharging liquid, and the rotating mechanism 400 drives the test tube rack 500 to continue rotating to the capping station for capping, and at the same time, the next test tube 600 moves to the filling station for liquid filling. The above process is repeated until a preset number of test tubes 600 or all test tubes 600 on the test tube rack 500 are filled and capped. After filling, the medical staff can directly remove the test tube rack 500 together with the test tubes 600 from the medical liquid filling device for subsequent operations.

[0130] Combination Figure 1-Figure 3The liquid storage tank 210 is arranged at the top of the bracket assembly 100 to facilitate the discharge of liquid. The specific shape of the liquid storage tank 210 is not limited. A second solenoid valve 220 is arranged at the top of the liquid storage tank 210. The second solenoid valve 220 is used as an air inlet valve to ensure the air pressure balance in the liquid storage tank 210 so that the liquid can fall smoothly. In addition, the second solenoid valve 220 is also used to prevent the liquid in the liquid storage tank 210 from volatilizing.

[0131] In order to achieve quantitative control of liquid filling, combined with Figure 5 and Figure 6 The quantitative control component includes a manual control valve 221, a first solenoid valve 222 and a filling nozzle 223. The manual control valve 221 can be a ball valve and is connected and arranged between the liquid storage tank 210 and the liquid outlet pipeline 211, so as to allow medical staff to manually control the connection and cutoff of the liquid outlet pipeline 211. The first solenoid valve 222 is connected and arranged between the outlet of the manual control valve 221 and the liquid outlet pipeline 211, so as to control the connection and cutoff of the liquid outlet pipeline 211; the filling nozzle 223 is connected and arranged at the liquid outlet of the liquid outlet pipeline 211, and the filling station is opposite to the liquid outlet of the filling nozzle 223.

[0132] Specifically, the quantitative control component can control the liquid output by the opening time of the first electromagnetic valve 222. In some embodiments, the quantitative control component further includes a flow meter, and the quantitative control component measures the liquid output in the liquid outlet pipeline 211 by the flow meter, and controls the opening time of the first electromagnetic valve 222 accordingly, thereby realizing accurate control of the filling liquid amount. Along the liquid outlet direction of the liquid outlet pipeline 211, the first electromagnetic valve 222 can be set at the upstream position or downstream position of the flow meter.

[0133] The relative positions of the first solenoid valve 222, the manual control valve 221, the flowmeter and the liquid outlet pipeline 211 can be interchanged. In one embodiment, the second solenoid valve 220 is arranged on the top of the liquid storage tank 210, the liquid outlet is arranged on the bottom of the liquid storage tank 210, the manual control valve 221 is arranged at the liquid outlet, and the manual control valve 221 is sealed and connected with the liquid outlet of the liquid storage tank 210 through the first connecting nut and the first sealing gasket; the liquid outlet pipeline 211 is a bendable silicone hose, and the first end of the silicone hose is provided with a hose connector, and the hose connector is threadedly connected with the threaded connector at the outlet of the manual control valve 221, and the two are sealed by the second connecting nut and the second sealing gasket; the second end of the silicone hose is connected to the flowmeter, and the outlet of the flowmeter is connected with the first solenoid valve 222, the first solenoid valve 222 is fixed on the bracket assembly 100, and the outlet of the first solenoid valve 222 is installed with a nozzle 223, and the nozzle 223 is fixed on the bracket assembly 100 through the nozzle bracket 224. The filling nozzle 223 is made of a rigid material to ensure stable liquid discharge.

[0134] When liquid filling is performed, the liquid flows out from the liquid storage tank 210 , passes through the manual control valve 221 , the silicone hose, the flow meter and the first electromagnetic valve 222 in sequence, and finally flows to the test tube 600 through the filling nozzle 223 .

[0135] Those skilled in the art will appreciate that the height between the filling nozzle 223 and the test tube 600 can be adjusted according to actual conditions, as long as it is ensured that the liquid does not splash.
