Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A bone marrow chromosome culture medium precision dispensing instrument includes a stable base 1, an auxiliary structure 2 attached to the inner side of the stable base 1, a protective shell 3 attached to the stable base 1, and a discharge structure 4 attached to the rear side of the top of the stable base 1.

[0027] The auxiliary structure 2 includes a mounting base 21, a rotating component 22, a placement disk 23, a fixing ring 24, a connecting block 25, and a stepper motor 26. The bottom of the mounting base 21 is bolted to the top of the stabilizing base 1. The inner wall of the mounting base 21 is rotatably connected to the outer wall of the rotating component 22. The top of the rotating component 22 is bolted to the bottom of the placement disk 23. The top of the placement disk 23 is fixedly connected to the bottom of the fixing ring 24. The bottom of the rotating component 22 is fixedly connected to the top of the connecting block 25. The outer wall of the connecting block 25 is rotatably connected to the inner wall of the mounting base 21. The bottom of the connecting block 25 is bolted to the top of the stepper motor 26. The top of the stepper motor 26 is bolted to the bottom of the stabilizing base 1.

[0028] In this embodiment: the stabilizing seat 1 serves as the base of the whole, providing stable support for the dispensing of bone marrow chromosome culture medium. The protective shell 3 installed on the top of the stabilizing seat 1 is used to protect the dispensing of bone marrow chromosome culture medium. The dispensing structure 4 installed on the top of the stabilizing seat 1 is used to dispense the dispensing of bone marrow chromosome culture medium. When the user needs to package the bone marrow chromosome culture medium, firstly, the user places six receiving containers on the inner walls of six fixing rings 24 respectively. The fixing rings 24 are fixed to the top of the placement tray 23, so that the containers are stabilized on the placement tray 23. The bone marrow chromosome culture medium can be added to the containers by controlling the dispensing structure 4. During the addition process, the user starts the stepper motor 26. The operation of the stepper motor 26 will drive the rotating component 22 to rotate through the connecting block 25, thereby driving the placement tray 23 set on the top of the rotating component 22 to rotate. The rotation of the rotating component 22 is located on the inner wall of the mounting base 21, and the mounting base 21 is bolted to the top of the stabilizing seat 1 to stabilize the rotation of the rotating component 22.

[0029] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, the discharge structure 4 includes a mounting frame 41, the bottom of which is bolted to the rear side of the top of the stabilizing seat 1, and an electrically controlled telescopic device 42 is bolted to the bottom of the mounting frame 41.

[0030] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, a connector 43 is bolted to the bottom of the electrically controlled expansion joint 42, and a discharge block 44 is threaded to the bottom of the connector 43.

[0031] Specifically, such as Figure 3 , Figure 4 , Figure 5 As shown, the left side of the connector 43 is threaded with a guide tube 45, and the right side of the guide tube 45 is threaded with an electronically controlled infusion set 46. The bottom of the electronically controlled infusion set 46 is bolted to the top of the protective shell 3.

[0032] In this embodiment: the discharge structure 4 is provided, wherein the mounting frame 41 is bolted to the top of the stabilizing base 1, serving as the stable foundation for the discharge structure 4. When the user needs to dispense bone marrow chromosome culture medium, firstly, the prepared bone marrow chromosome culture medium is filled into the existing electronically controlled infusion set 46. The operation of the electronically controlled infusion set 46 delivers the bone marrow chromosome culture medium to the connector 43 through the guide tube 45. Finally, it can be released through the discharge block 44 connected and communicated at the bottom of the connector 43, so that the bone marrow chromosome culture medium can be dripped to the top of the auxiliary structure 2. The precise control of the electronically controlled infusion set 46 can achieve the function of quantitative measurement. By setting an electronically controlled telescopic device 42 connected between the mounting frame 41 and the connector 43, the function of controlling the discharge position of the connector 43 and the discharge block 44 can be achieved.

[0033] Specifically, such as Figure 5 As shown, the top of the protective shell 3 is provided with a mating hole 5, and the inner wall of the mating hole 5 is movably connected to the outer wall of the guide tube 45.

[0034] Specifically, such as Figure 5 As shown, the bottom of the stabilizer 1 has a connection hole 6, through which the stepper motor 26 passes and is connected to the connecting block 25.

[0035] In this embodiment: the mating hole 5 opened in the protective shell 3 allows the guide tube 45 to be connected between the electronically controlled infusion set 46 and the connector 43 through the protective shell 3, so that the electronically controlled infusion set 46 can feed the material to the connector 43 through the guide tube 45. The stepper motor 26, which is bolted to the bottom of the stabilizer 1, can be connected to the bottom of the connector block 25 through the stabilizer 1 through the connection hole 6 opened in the bottom of the stabilizer 1, so that the stepper motor 26 can control the rotating part 22 to rotate through the connector block 25.

[0036] Specifically, such as Figure 2 As shown, the bottom of the mounting base 21 has a mounting hole 7, the inner wall of the mounting hole 7 is rotatably connected to the outer wall of the connecting block 25, and the top of the connecting block 25 passes through the mounting base 21 and is connected to the bottom of the rotating part 22.

[0037] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, a support rod 8 is fixedly connected to the bottom of the stabilizer 1, and an anti-slip block 9 is threadedly connected to the bottom of the support rod 8.

[0038] In this embodiment: the mounting hole 7 at the bottom of the mounting base 21 allows the connecting block 25 to penetrate the mounting base 21 and connect with the rotating member 22, so that the rotating member 22 and the connecting block 25 can rotate simultaneously. The support rod 8 fixed at the bottom of the stabilizing base 1 is used to support the bottom of the stabilizing base 1, and the anti-slip block 9 is connected to the bottom of the support rod 8 to further increase the stability of the stabilizing base 1.

[0039] Working principle: When bone marrow chromosome culture medium needs to be dispensed, the user places six receiving containers on the inner walls of six fixing rings 24, which are fixed to the top of the placement tray 23, stabilizing the containers on the tray 23. The prepared bone marrow chromosome culture medium is then filled into the existing electronically controlled infusion set 46. The operation of the electronically controlled infusion set 46 delivers the bone marrow chromosome culture medium to the connector 43 through the guide tube 45. It can then be released through the discharge block 44 connected to the bottom of the connector 43, allowing the bone marrow chromosome culture medium to drip into the container. During the addition process, the user starts the stepper motor 26. The operation of the stepper motor 26 drives the rotating part 22 to rotate through the connecting block 25, thereby rotating the placement tray 23 set on the top of the rotating part 22.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
