Optionally, the fan assembly 300 further comprises an auxiliary fan. The auxiliary fan is disposed in the second air duct 140, and the air volume of the second air duct 140 can be increased by the auxiliary fan, so that the air in the operation chamber 120 can rapidly enter the filter chamber 110 through the second air duct 140, and a negative pressure environment can be rapidly formed in the operation chamber 120.

In some embodiments, the housing 100 is divided into two spaces by a partition. The partition is horizontally disposed, and the upper space serves as a filter chamber 110 and the lower space serves as an operation chamber 120.

Optionally, the first air duct 130 vertically penetrates through the partition plate, an air inlet 121 of the first air duct 130 is communicated with the filtering chamber 110, and an air outlet of the first air duct 130 is communicated with the operation chamber 120. Thus, the air in the filter chamber 110 is blown into the operation chamber 120 from the top down through the first air duct 130, and the vortex of the air flow in the operation chamber 120 can be prevented. Here, the average velocity of the descending air stream is controlled between 0.25m/s and 0.5m/s by the fan assembly 300.

The second filter part 220 is disposed in the second air duct 140 for filtering the air passing through the second air duct 140. Air in the operation chamber 120 enters the second air duct 140 through the air inlet 121 of the second air duct 140, and the air in the second air duct 140 circulates toward the filter chamber 110 under the action of the fan assembly 300. At this time, under the action of the second filtering portion 220, the air is firstly filtered and then flows to the filtering chamber 110 through the second air duct 140. Under the action of the fan assembly 300, the air in the filter chamber 110 is circulated to the operation chamber 120 through the first air duct 130. At this time, the air is filtered again by the first filter portion 210, and then flows to the operation chamber 120 through the first air path 130. Thus, the air in contact with the blood sample in the operation chamber 120 is sufficiently purified through two times of filtering, and the air flows toward the operation chamber 120 again along the second air path 140 and the first air path 130 in sequence.

Optionally, the operation chamber 120 is opened with an air inlet 121. The air inlet 121 is disposed on a side plate of the operation chamber 120, and external air enters the operation chamber 120 through the air inlet 121. After the external air enters the operation chamber 120, the external air is mixed with the air in the operation chamber 120, and then the mixed air enters the second air duct 140 through the air inlet 121 of the second air duct 140. Here, the average flow velocity of the air flow entering the operation chamber 120 through the air inlet 121 is not less than 0.5 m/s.

Optionally, the blood separation workstation further comprises a wind speed detection assembly. The wind speed detection assembly includes a first sensor, a second sensor, and a third sensor. The first sensor is disposed at the air inlet 121 and is configured to detect a flow rate of air entering the operation chamber 120 from the air inlet 121; the second sensor is disposed in the first air duct 130, and is configured to detect a flow rate of air entering the operation chamber 120 through the first air duct 130; the third sensor is disposed in the operation chamber 120, and detects a flow rate of air in the operation chamber 120. Thus, the air speed detecting assembly can detect the flow speed of the air flow inside the air inlet 121, the first air duct 130 and the operation chamber 120 at any time.

Optionally, the operation chamber 120 is opened with a detection port 122. The detection port 122 is provided on one side plate of the operation chamber 120, or the detection port 122 is provided on a partition plate. The relevant parameters of the air in the operation room 120 can be detected by using the relevant detection equipment through the detection port 122, so that the user can know the quality of the air in the operation room 120 conveniently.

Optionally, the filtering chamber 110 is connected to the external environment through a third air duct 150, and the fan assembly 300 is further configured to blow air in the filtering chamber 110 to the external environment through the third air duct 150. The third air duct 150 vertically penetrates the top of the filtering chamber 110, an air inlet 121 of the third air duct 150 is communicated with the filtering chamber 110, and an air outlet of the third air duct 150 is communicated with the external environment. Under the action of the fan assembly 300, there are two flow paths for the air in the filter chamber 110. One flow path is through the first air duct 130 to the process chamber 120 and the other flow path is through the third air duct 150 to the outdoor environment. Here, the first air duct 130 is vertically opened at the top of the operation chamber 120, and the third air duct 150 is vertically opened at the top of the filter chamber 110, so that the air in the filter chamber 110 rapidly descends and flows back to the operation chamber 120, or rapidly ascends and is discharged to the external environment.

Optionally, the blood separation workstation further comprises an air guide assembly. The air guide assembly comprises an air guide plate and a first controller, wherein the air guide plate is arranged at the air outlet of the third air duct 150, and the air guide plate is driven by the air guide motor to rotate so as to shield the air outlet of the third air duct 150; the first controller is electrically connected to the air guide motor for controlling the air guide motor to rotate to adjust the opening of the air guide plate, so as to adjust the air output of the third air duct 150.

Illustratively, the opening of the air deflector ranges from 0 ° to 90 °. When the first controller adjusts the opening of the air deflector to 0 degrees, the air outlet of the third air duct 150 is not blocked, and the air outlet volume of the third air duct 150 is maximum at the moment; the first controller completely blocks the air outlet of the third air duct 150 when the opening degree of the air deflector is adjusted to 90 degrees, and the air outlet volume of the third air duct 150 is the minimum at the moment. Because there are two paths for air within the filter chamber 110, one path is directed to the process chamber 120 through the first air duct 130 and the other path is directed to the outdoor environment through the third air duct 150. Therefore, the air output of the first air duct 130 can be indirectly adjusted by adjusting the air output of the third air duct 150. For example, in the case that the opening degree of the air deflector is increased to reduce the air output of the third air duct 150, the air output of the first air duct 130 to the operation chamber 120 is increased; in the case where the opening degree of the air guide plate is decreased to increase the air output of the third air duct 150, the air output of the first air duct 130 to the operation chamber 120 is decreased. Therefore, the air output of the first air duct 130 is indirectly adjusted by controlling the opening of the air deflector.

Optionally, the fan assembly 300 further comprises a second controller. The second controller is electrically connected to the fan and is used for controlling the power of the fan. The second controller controls the power of the fan, so as to adjust the air output of the first air duct 130 and the third air duct 150. For example, when the second controller controls the power of the fan to increase, the air output of the first air duct 130 and the third air duct 150 increases; when the second controller controls the power of the fan to decrease, the air output of the first air duct 130 and the third air duct 150 decreases.

It can be understood that the air output of the first air duct 130 can be better controlled by controlling the power of the fan and controlling the opening of the air deflector, so as to maintain the average air flow of the air in the operation room 120 at a certain level.

Optionally, the filter assembly 200 further comprises a third filter portion 230. The third filter 230 is disposed in the third air duct 150 for filtering the air passing through the third air duct 150. Air in the operation chamber 120 enters the second air duct 140 through the air inlet 121 of the second air duct 140, and the air in the second air duct 140 circulates towards the filter chamber 110 under the action of the fan assembly 300. At this time, under the action of the second filtering portion 220, the air is firstly filtered and then flows from the second air duct 140 to the filtering chamber 110. Under the action of the fan assembly 300, the air in the filter chamber 110 is circulated to the external environment through the third air duct 150. At this time, the air is filtered again by the third filter 230 and then flows from the third air duct 150 to the external environment. In this way, the air contacting the blood sample in the operation chamber 120 is sufficiently purified after being filtered twice, and the air is discharged to the external environment along the second air duct 140 and the third air duct 150 in sequence, thereby preventing the external environment from being polluted.

Alternatively, the first filter part 210, the second filter part 220, and the third filter part 230 each include one air filter. Here, the types of air filters include, but are not limited to, PTFE filters, glass fiber filters, electrostatic filters, activated carbon fiber filters. The main material of the PTFE filter is polytetrafluoroethylene, and the material has wide chemical applicability, hydrophilicity and hydrophobicity. The filter has high retention rate, good thermal stability and chemical resistance, good strength and resistance to impact of forward and reverse pressure. The glass fiber filter adopts glass fiber filter paper as a material, and the material has the advantages of multiple types, good insulativity, high strength, good heat resistance and strong corrosion resistance, and has the defects of brittle material and non-wear resistance. The electrostatic filter charges particles using a high-voltage electrostatic field, and then the particles are trapped by a dust collecting plate. The inside of the filtering material of the activated carbon fiber filter has a strong loose porous structure and strong adsorbability, and has good adsorption and killing performance on toxic, harmful and peculiar smell gases and bacteria in the air.

Optionally, the blood separation workstation further comprises a sterilization assembly. The sterilization assembly includes an ultraviolet lamp disposed at the top of the operation chamber 120, or disposed around the inner wall of the side plate of the operation chamber 120. The ultraviolet lamp irradiates the operation room 120 through ultraviolet light, and the ultraviolet light has the sterilization and disinfection effects, so that the air in the operation room 120 is purified.
