[0030] like Figure 1 As shown, in one embodiment of the present invention, the laminar flow device for medical equipment includes a laminar flow filtering mechanism 100, an equipment support component 200 and a support mechanism 300; the support mechanism 300 is arranged on the equipment support component 200, and the upper surface of the support mechanism 300 is used to place the medical equipment; the laminar flow filtering mechanism 100 includes a protective shell 1, a filtering component 2 and a laminar flow generator 3; the protective shell 1 is arranged on the equipment support component 200; the laminar flow generator 3 is arranged inside the protective shell 1; and the output end of the laminar flow generator 3 faces the input end of the filtering component 2; the filtering component 2 is arranged inside the protective shell 1; and the output end of the filtering component 2 faces the upper surface of the equipment support component 200.
[0031] The technical solution of the present invention improves the delivery volume and speed of the airflow to be processed through a laminar flow generator combined with the filtering effect of the filter component on high-speed and large amounts of airflow, thereby providing a sterile microenvironment for the support mechanism placed on the medical device, and ensuring the convenience of grabbing and placing the medical device, thereby forming a stable and reliable clean laminar flow coverage area for the use environment of the device, discharging air containing bacterial particles outside the laminar flow air, so that the surgical environment is not polluted; and improving the safety and convenience of the use of medical devices.
[0032] Specifically, in some embodiments, Figure 1 and 2As shown, the instrument support component 200 includes a movable plate 210 and a positioning plate 220; the positioning plate 220 is fixedly connected to the support mechanism 300; one side end of the movable plate 210 is swingably connected to one side end of the positioning plate 220; and the bottom of the movable plate 210 abuts against the support mechanism 300. The movable plate 210 is hingedly connected to the side end of the positioning plate 220. In other words, the flow rate and flow of the laminar filtered gas are adjusted according to the requirements of environmental needs; thereby, the movable plate 210 is swung toward the direction of the filter component 2, and the laminar filtered gas can be reflected back to the medical device on the positioning plate 200 to a certain extent, thereby improving the utilization rate of the gas and preventing the medical device from falling off the positioning plate 200.
[0033] Specifically, in some embodiments, Figure 1 As shown, the support mechanism 300 includes a connection carrier 310 and a mobile carrier 320; one end of the connection carrier 310 is connected to the device support component 200; the other end of the connection carrier 310 is connected to the mobile carrier 320. Figure 2 As shown, the connecting carrier 310 includes a first connecting rod 311, an adjusting sleeve rod 312 and a second connecting rod 313; one end of the first connecting rod 311 is connected to the instrument support component 200 (middle positioning plate 220); one end of the adjusting sleeve rod 312 is sleeved on the other end of the first connecting rod 311; the other end of the adjusting sleeve rod 312 is sleeved on one end of the second connecting rod 313; the other end of the second connecting rod 313 is connected to the mobile carrier 320. Furthermore, the outer wall of one end of the first connecting rod 311 is tightly attached to or connected to the inner wall of one end of the adjusting sleeve rod 312 by a fixing bolt; the outer wall of the other end of the second connecting rod 313 is tightly attached to or connected to the inner wall of the other end of the adjusting sleeve rod 312 by a fixing bolt. Wherein, as Figure 2 As shown, at least one universal wheel 321 is provided at the bottom of the mobile carrier 320. Furthermore, there are four universal wheels 321 arranged in an array at the bottom of the mobile carrier 320. This structure ensures the convenience of movement of the laminar flow device, thereby improving the convenience of use.
[0034] Specifically, in some embodiments, Figure 1 and 2As shown in Figure 4, a swing adjustment mechanism 5 is provided between the support mechanism 300 and the device support part 200; the swing adjustment mechanism 55 includes a bracket 51 and a swing part 52; the device support part 200 is connected to the bracket 51; the bracket 51 is connected to the support mechanism 300; the swing part 52 is connected to the bracket 51; and the protective shell 1 is connected to the swing part 52. This structure is positioned and fixed to one side end of the swing adjustment mechanism 5 by the support mechanism 300; combined with the protective shell 1, it swings at a certain angle as needed to adapt to more different environments and the use of different devices, thereby improving the convenience of use. Among them, as Figure 2 and 4 As shown in Figure 5, the swing component 52 includes a first connecting plate 521, a second connecting plate 522 and a driving component 523; the first connecting plate 521 is fixedly connected to the bracket 51; one side end of the second connecting plate 522 is hinged to one side end of the first connecting plate 521; the protective shell 1 is connected to the second connecting plate 522; the mounting end of the driving component 523 is connected to the second connecting plate 522; and the movable end of the driving component 523 is connected to the first connecting plate 521. Figure 4 and 5 As shown, the driving component 523 includes a driving motor 524, a rotating shaft 525 and a connecting block 526; the driving motor 524 is connected to the second connecting plate 522 and is transmission-connected to one end of the rotating shaft 525; the other end of the rotating shaft 525 passes through the first connecting plate 521 and is movably connected to the connecting block 526; the connecting block 526 is swingably connected to the second connecting plate 522. Preferably, the connecting block 526 is hingedly swingably connected to the second connecting plate 522. That is, under the forward and reverse rotation of the driving motor, the connecting block 526 is pushed by the rotation of the rotating shaft 525 (helical shaft), and the connecting block 526 moves upward or downward, thereby causing the second connecting plate 522 to swing upward or downward, so as to change the outlet direction of the laminar gas of the protective shell 1, thereby improving the convenience of use and coverage.
[0035] Specifically, in some embodiments, Figure 1 and 3 As shown, the interior of the protective housing 1 is sequentially provided with a laminar flow conveying cavity 101 and a filter cavity 102 along the laminar flow conveying direction A. The laminar flow generator 3 includes at least one first laminar flow fan 31 and at least one second laminar flow fan 32. The second laminar flow fan 32, the first laminar flow fan 31, and the filter component 2 are sequentially arranged along the laminar flow conveying direction A. This structure, through the dual laminar flow drive, can improve the compactness of the structure, increase the delivery volume and speed of the airflow to be processed, and effectively enhance the uniformity and area of laminar flow coverage.
[0036] Specifically, in some embodiments, Figure 3 As shown, the number of the first laminar flow fans 31 is at least nine, and they are arranged in an array (3*3, etc.) inside the laminar flow conveying cavity 101; the number of the second laminar flow fans 32 is at least four, and they are arranged in an array (2*2, etc.) at the opening of the laminar flow conveying cavity 101; and the laminar flow coverage area of all the first laminar flow fans 31 is greater than or equal to the laminar flow coverage area of all the second laminar flow fans 32. Preferably, the laminar flow coverage area of all the first laminar flow fans 31 is greater than the laminar flow coverage area of all the second laminar flow fans 32. This structure can effectively increase the amount and speed of gas, and can also reduce the noise generated by the device, thereby improving the comfort of the use environment. Among them, the second laminar flow fan 32 uses a guide fan with a diameter of 8cm, 12cm or 15cm; the first laminar flow fan 31 uses a guide fan with a diameter of 8cm, 12cm or 15cm. That is to say, the machine should be turned on and run for at least 10 minutes before the operation, and the air volume of the first laminar flow fan 31 and the second laminar flow fan 32 should be changed by adjusting the knob; and the wind speed should be measured 20 cm away from the splash screen, and the control switches of the first laminar flow fan 31 and the second laminar flow fan 32 should be adjusted to make the wind speed value 0.45 m / s ± 10%.
[0037] Specifically, in some embodiments, Figure 3 As shown, the filter component 2 includes an air filter 21 and an air filter membrane 22. The air filter membrane 22 is mounted on the protective housing 1 at the outlet of the filter chamber 102. The air filter 21 is mounted on the protective housing 1 between the air filter membrane 22 and the laminar flow generator 3. This structure further improves the quality of the laminarly delivered gas through double-layer filtration of laminar flow gas, thereby achieving a stable and reliable clean laminar flow coverage area at the surgical site. Furthermore, the mesh air filter 21, positioned relatively close to the laminar flow generator 3, reduces impact damage to the air filter portion, buffers its velocity to a certain extent, and ensures the filtration quality. The air filter 21 is made of PTFE (polytetrafluoroethylene) or nanofiber carbon, while the air filter membrane 22 is made of synthetic fiber or glass fiber. This structure effectively increases the hardness of the air filter membrane 22, reduces deformation caused by excessive laminar flow, and prevents changes in its mesh size, thereby improving operational stability and ensuring filtration effectiveness.
[0038] Specifically, in some embodiments, Figure 3 and 4As shown, the protective shell 1 is further provided with a data acquisition component 4; the data acquisition component 4 comprises a view collector 41, a dust detector 42 and a fluid flow rate sensor 43; the view collector 41 is used to collect view information of the environment where the protective shell 1 is located; the dust detector 42 is used to collect dust information of PM2.5 of the environment where the protective shell 1 is located; and the fluid flow rate sensor 43 is used to collect gas flow rate information at the outlet of the filter cavity 102.
