[0005] Furthermore, the automatic sealing door includes a sealing door and a lifting drive mechanism connected to the sealing door.

[0006] Furthermore, the perfusion device also includes a reverse suction device.

[0007] Furthermore, a lighting device is arranged in the shell.

[0008] Compared with the prior art, the effects of the present invention are positive and obvious.

[0009] 1. The present invention realizes the automation of specimen fixation. When fixing the specimen, there is no need to manually perfuse the formaldehyde solution and the packaging container, which reduces the participation of personnel as much as possible, prevents the skin, mucous membrane and respiratory tract from being damaged by formaldehyde, and plays an occupational protection role.

[0010] 2. The weighing sensor and pump body can weigh and adjust the amount of perfusion solution added respectively. The synergistic effect of the two can ensure that the amount of specimen solution added meets the industry standard (industry standard: the solution volume is 3-5 times the specimen volume, and the density of human tissue is close to that of water), thereby improving the accuracy of the fixed perfusion solution volume of the specimen.

[0011] 3. After the staff is placed in the container, the filling device and the plastic sealing device will automatically close the sealing door when working, the shell will be a closed environment, and sufficient ventilation will be carried out to minimize the volatilization and diffusion of formaldehyde, thereby avoiding direct contact between the staff and the formaldehyde liquid and preventing formaldehyde pollution.

[0016] The present invention is further described below in conjunction with an embodiment, but the present invention is not limited to the embodiment, and any similar structure and similar changes of the present invention should be included in the protection scope of the present invention. The use of directions such as up, down, front, back, left, and right in the present invention is only for the convenience of clear description, and is not a limitation of the technical solution of the present invention.

[0017] like Figure 1-Figure 4 As shown, an automated specimen fixer of the present invention comprises a shell 1, an automatic sealing door 4 is arranged on the side of the shell 1, an electric slide rail 2 is arranged in the shell 1, a tray 3 is arranged on the electric slide rail 2, a weighing sensor is arranged in the tray 3, a perfusion device 5 is arranged above the electric slide rail 2 in the shell 1, the perfusion device 5 comprises a liquid storage device 6, the liquid storage device 6 is connected to a pump body through a pipeline, and the pump body is connected to a perfusion nozzle 8 through a pipeline, a plastic sealing device 9 is further arranged above the electric slide rail 2 and on one side of the perfusion device 5 in the shell 1, an exhaust device 10 is arranged on the top of the shell 1, a controller 7 is arranged in the shell 1, and the control ends of the automatic sealing door 4, the electric slide rail 2, the perfusion device 5, the plastic sealing device 9 and the exhaust device 10, and the signal output end of the weighing sensor are all connected to the controller 7.

[0018] Furthermore, the automatic sealing door 4 includes a sealing door and a lifting drive mechanism connected to the sealing door.

[0019] Furthermore, the perfusion device 5 also includes a reverse suction device.

[0020] Specifically, the reverse suction device includes a suction pump, which reversely sucks formaldehyde in the dead space area of ​​the infusion port after infusion, which is difficult to be completely discharged due to poor liquid flow or structural design, to prevent it from dripping out in the subsequent process due to gravity or other factors.

[0021] Furthermore, a lighting device is disposed in the housing 1 .

[0022] Specifically, the automatic sealing door 4, electric slide rail 2, tray 3, weighing sensor, filling device 5, liquid storage 6, pump body, filling nozzle 8, plastic sealing device 9, exhaust device 10, controller 7, reverse suction device, suction pump, lifting drive mechanism, etc. in this embodiment all adopt well-known solutions in the prior art, which are well understood by those skilled in the art and will not be elaborated here.

[0023] The working principle of this embodiment:

[0024] The container containing the tissue specimen is placed on the tray 3. Under the control of the controller 7, the automatic sealing door 4 is closed, and the electric slide rail 2 drives the tray 3 to move to the bottom of the perfusion device 5. The pump body pours the formaldehyde solution in the liquid storage tank 6 into the container through the pipeline and the perfusion nozzle 8. After being weighed by the weighing sensor and reaching the target weight, the perfusion is stopped. Then the electric slide rail 2 drives the tray 3 to move to the bottom of the plastic sealing device 9. The plastic sealing device 9 plastic seals the container. At the same time, the exhaust device 10 starts to exhaust. Then the automatic door is opened and the container is taken away.

[0025] Advantages of the present invention:

[0026] 1. The present invention realizes the automation of specimen fixation. When fixing the specimen, there is no need to manually perfuse the formaldehyde solution and the packaging container, which reduces the participation of personnel as much as possible, prevents the skin, mucous membrane and respiratory tract from being damaged by formaldehyde, and plays an occupational protection role.

[0027] 2. The weighing sensor and pump body can weigh and adjust the amount of perfusion solution added respectively. The synergistic effect of the two can ensure that the amount of specimen solution added meets the industry standard (industry standard: the solution volume is 3-5 times the specimen volume, and the density of human tissue is close to that of water), thereby improving the accuracy of the fixed perfusion solution volume of the specimen.

[0028] 3. After the staff is placed in the container, the filling device 5 and the plastic sealing device 9 automatically close the sealing door 4 when working, the shell 1 is a closed environment, and sufficient exhaust is carried out to reduce the volatilization and diffusion of formaldehyde as much as possible, thereby avoiding direct contact between the staff and the formaldehyde liquid and preventing formaldehyde pollution.

[0029] The present invention is suitable for being placed in operating rooms, laboratories, specimen preparation units and other departments that need to fix and package tissue specimens. Exhaust ducts, information ports and circuits are reserved before installation. If larger specimens need to be fixed, the size can be designed according to actual conditions.
