Description

Technical Field

[0001] The present application relates to the technical field of perfusion tanks, and in particular to a sterilizing pot suitable for perfusion tanks and a sterilizing method thereof. Background Art

[0002] The blood perfusion device is a Class III medical device and also needs to be sterilized during the production process to ensure that it is in a sterile state during clinical use.

[0003] At present, the mainstream sterilization method of hemoperfusion devices is pasteurization, which is a sterilization method invented by French scientist Pasteur. Its target is mainly pathogenic microorganisms and other growing bacteria. Pasteurization refers to the process of placing multiple perfusion tanks in a pot, heating them to a certain temperature for a period of time, and then cooling them quickly to kill fermentation microorganisms that may cause disease, deterioration or unnecessary.

[0004] Multiple perfusion tanks are placed in a static state in the pot, so it takes a long time to heat to a specified temperature, and the heat conduction is not uniform. At the same time, the subsequent cooling also takes a long time, thereby reducing the sterilization efficiency and effect of the perfusion tank. Summary of the invention

At the same time, the control mechanism starts to heat the perfusion device tank body, and the mixing mechanism promotes the hot air to move faster, so that the hot air flows faster and more evenly. After heating to the specified temperature, the heating stops, and the placement box continues to rotate, so that the mixing mechanism continues to make the hot air flow in the pot body, and then the control mechanism starts to cool the perfusion device tank body, thereby greatly improving the sterilization efficiency and effect of the perfusion device tank body.

[0013] Optionally, the mixing mechanism includes:

[0014] A mixing hood, which is disposed on one end of the pot body and communicated with the pot body;

[0015] A rotating rod, the rotating rod is rotatably disposed on the mixing cover and connected to the driving assembly;

[0016] A fan blade is arranged on the rotating rod and is located in the mixing hood and pushes the gas into the pot body;

[0017] A reflux pipe is arranged on one end of the pot body away from the mixing hood and is connected with the pot body and the mixing hood. After the fan blade rotates, the gas in the pot body flows back into the mixing hood through the reflux pipe.

[0018] By adopting the above technical solution, the driving component is started to drive the rotating rod to rotate, and the rotation of the rotating rod drives the fan blades to rotate, so that the return pipe generates suction, and the suction pushes the gas in the pot body into the mixing hood through the return pipe, and then the gas enters the other end of the pot body, so that the gas in the pot body forms a circulation flow, thereby accelerating the airflow in the pot body, thereby improving the sterilization efficiency and effect of the perfusion tank body; and the flow of the placement box and the gas is accelerated by the driving component, thereby improving the energy saving effect.

The cooling efficiency is greatly improved by the extraction method. At the same time, the rotation of the placement box also makes the extraction speed faster and the extraction effect better. The extraction of hot steam also greatly reduces the resistance when the placement box rotates, further improving the extraction efficiency and effect. When it needs to be removed, the fan blades and the placement box are rotated and closed, and the outside air can still enter the pot body through the cooling component, and then the pot body can be opened to remove the placement box, thereby improving the sterilization efficiency and effect of the perfusion device tank body.

When cooling is required, the first tube body and the air inlet pipe are closed and the connecting pipe and the second tube body are opened. The hot steam in the pot body enters the recovery box under the action of the fan blades, so as to achieve rapid cooling of the perfusion tank body. When the placement box needs to be taken out, the second tube body is closed and the first tube body is opened, and the fan blades and the placement box stop running at the same time, and then the placement box can be replaced to continue sterilization, thereby improving the sterilization efficiency and effect of the perfusion tank body.

[0072] The guide assembly 5 is arranged on the first placement plate 41 and the second placement plate 42 and is used to guide and protect the perfusion device tank body. At least one guide assembly 5 is arranged in a placement space 44. There can also be multiple guide assemblies 5 spaced along the length direction of the placement box 22, and the multiple guide assemblies work together to guide and protect the perfusion device tank body, thereby avoiding the ventilation holes and reducing the blocking effect on the ventilation holes.

[0073] The guide assembly 5 includes a first guide block 51 and a second guide block 52, which are respectively fixedly mounted on the side walls of the first placement plate 41 and the second placement plate 42 on opposite sides.

The placement box 22 is placed in the pot body 1, and the driving assembly 23 is started to rotate the blades 63 and the placement box 22 simultaneously. The placement box 22 stirs the gas in the pot body 1, and the rotation of the blades 63 causes the gas in one end of the pot body 1 to enter the other end of the pot body 1 through the return pipe 64, so that the gas flow rate in the pot body 1 is faster and more uniform, thereby greatly improving the sterilization efficiency and effect of the perfusion tank.

[0078] The driving assembly 23 includes a driving motor 24, a ring gear 25, a main gear 26 and a sub gear 27. The driving motor 24 is fixedly mounted on the mixing cover 61 and the output shaft is connected to the rotating rod 62, so as to drive the rotating rod 62 to rotate; the ring gear 25 is coaxially fixedly mounted on the rotating shaft 12, so as to connect the ring gear 25 to the placement ring 21, and the main gear 26 is key-connected to one end of the rotating rod 62 close to the rotating shaft 12, and the main gear 26 is located on the inner side of the ring gear 25.

[0080] Reference Figure 2 and Figure 4The control mechanism 7 includes a steam tank 71, an air intake pipe 72 and a cooling assembly 8.

The air intake pipe 72 is fixedly mounted on the steam tank 71 and is fixedly connected to the outer wall of the mixing cover 61. The air intake pipe 72 communicates the steam tank 71 and the mixing cover 61 and is fixedly mounted with an air intake valve 73 for controlling opening and closing. The cooling assembly 8 is arranged on the connecting pipe 65, and when the pot body 1 needs to be cooled, the cooling assembly 8 controls the connecting pipe 65 to communicate with the pot body 1, so that the hot steam in the pot body 1 is output to achieve cooling.

[0081] The cooling assembly 8 includes a first tube body 81, a second tube body 82, and a recovery box 83. The first tube body 81 and the second tube body 82 are both fixedly mounted on the connecting tube 65 and located on both sides of the axis of the connecting tube 65.

The recovery box 83 is fixedly mounted on one end of the second tube body 82 away from the connecting tube 65, and the recovery box 83 is used to recover the hot steam entering the second tube body 82. At the same time, when there is a lot of hot steam in the recovery box 83, the hot steam can be input into the steam tank 71 for reuse.

[0082] Reference Figure 1 and Figure 4 , the first valve 84 and the second valve 85 are closed and the connecting valve 66 is opened, so that the mixing hood 61 is connected with the pot body 1, and the fan blade 63 rotates to allow the gas in the mixing hood 61 to enter the pot body 1, and the return pipe 64 allows the gas at the other end of the pot body 1 to enter the mixing hood 61, so as to accelerate the flow of gas. At the same time, hot steam can also quickly enter the pot body 1 under the pressure in the steam tank body 71 and the suction force of the fan blade 63 to heat the perfusion tank body, thereby improving the heating efficiency and effect; when the pot body 1 reaches the specified temperature, the air inlet valve 73 is closed to input hot steam, and the specified temperature is maintained while the fan blade 63 continues to rotate to accelerate the flow of gas.
