[0008] A fixing mechanism is provided on the storage tray. The fixing mechanism includes a first vertical mesh plate, a second vertical mesh plate, and a horizontal support. The first vertical mesh plate and the second vertical mesh plate are arranged parallel to each other. The horizontal support is fixedly installed at the bottom of the second vertical mesh plate. The first vertical mesh plate, the second vertical mesh plate, and the horizontal support enclose a storage cavity for placing blood bags. The first vertical mesh plate is fixedly installed on the storage tray. Several horizontal rods are provided on the side of the second vertical mesh plate near the first vertical mesh plate. The horizontal rods are distributed around the second vertical mesh plate. A guide wheel is provided at the end of the horizontal rod away from the second vertical mesh plate. The guide wheel is slidably arranged in a guide slide. The guide slide is inclined. An automatic lifting mechanism is also provided between the rotating tray and the second vertical mesh plate. The automatic lifting mechanism is used to drive the second vertical mesh plate to reciprocate up and down when the storage tray rotates.

[0009] And a disinfection lamp installed on the inner wall of the device body is used to inactivate the virus in the blood bags on the fixing mechanism.

[0010] Furthermore, the driving mechanism includes a drive motor, which is fixedly mounted on the main body of the device, and the rotating disk is connected to the drive motor in a transmission manner.

[0011] Furthermore, the rotation mechanism includes an outer toothed ring sleeved on the outside of the storage disk and an inner toothed ring meshing with the outer toothed ring, the inner toothed ring being fixedly installed on the inner wall of the device body.

[0012] Furthermore, a support shaft is provided at the center of the storage disk, the support shaft is rotatably mounted on the rotating disk, and the support shaft is arranged in a circumferential array on the rotating disk.

[0013] Furthermore, the automatic lifting mechanism includes an abutment rod fixedly installed at the bottom of the second vertical mesh plate and a plurality of lifting protrusions arranged on the rotating disk. The plurality of lifting protrusions are arranged on the rotating disk with the supporting shaft as the center. During rotation, the abutment rod intermittently abuts against the lifting protrusions.

[0014] Furthermore, the guide slide includes a body and an inclined slide groove disposed on the side wall of the body, and the guide wheel is rotatably disposed in the inclined slide groove.

[0015] Furthermore, the storage tray includes a base and a top plate. The center of the base is fixedly sleeved on the support shaft. The center of the top plate is provided with a mounting through hole, through which the support shaft passes. An elastic element is provided between the top plate and the support shaft. The bottom of the first vertical mesh plate is fixedly installed on the storage tray. The base and the top plate are also provided with a lifting mechanism. The distance between the first end of the guide slide at the top and the first vertical mesh plate is L, and the distance between the second end of the guide slide at the bottom and the first vertical mesh plate is L, where L is greater than L.

[0016] Furthermore, the lifting mechanism includes a plurality of mating rods arrayed on the top of the chassis and an array of mating arc-shaped protrusions mounted on the top plate. The number of mating arc-shaped protrusions is equal to the number of mating rods, and the mating arc-shaped protrusions are arranged on the trajectory of the mating rods.

[0022] Turn on the disinfection lamp to inactivate the virus in the blood bags in the fixed device.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the driving mechanism drives the rotating disk to rotate, the rotating disk drives several storage disks to rotate, and at the same time, the storage disks also rotate under the action of the self-rotation mechanism. During the self-rotation, the automatic lifting mechanism drives the second vertical mesh plate to move up and down. During the up and down movement, the second vertical mesh plate, under the action of the guide wheel and guide slide, intermittently moves closer to the first vertical mesh plate to squeeze the blood bag, so that the blood in the blood bag is in a flowing state, ensuring that the blood in the blood bag can be completely inactivated. At the same time, the blood bag can not only revolve around the center of rotation of the rotating disk, but also rotate on its own axis, so that the blood bag can be fully irradiated by the disinfection lamp, which can effectively inactivate the virus. At the same time, the reciprocating squeezing of the blood bag by the second vertical mesh plate can effectively break up the ice fragments in the blood, which is convenient for subsequent processing.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Please see Figures 1 to 7The present invention provides a structural diagram of a virus inactivation device according to Embodiment 1. The virus inactivation device includes: a device body 10, a rotating mechanism 20, a fixing mechanism 30, and a disinfection lamp 40. The rotating mechanism 20, the fixing mechanism 30, and the disinfection lamp 40 are all installed in the device body 10. The rotating mechanism 20 includes a rotating disk 201 and a driving mechanism for driving the rotating disk 201 to rotate. The rotating disk 201 is rotatably installed at the bottom of the device body 10. A plurality of storage disks 203 are arranged in an array on the top of the rotating disk 201. A self-rotation mechanism is also provided between the storage disk 203 and the device body 10 to drive the storage disk 203 to rotate. Each storage disk 203 is provided with a fixing mechanism 30. The fixing mechanism 30 includes a first vertical mesh plate 301, a second vertical mesh plate 302, and a horizontal support 303. The first vertical mesh plate 301 and the second vertical mesh plate 302 are arranged parallel to each other, and the horizontal support 303 is fixed. Installed at the bottom of the second vertical mesh plate 302, the first vertical mesh plate 301, the second vertical mesh plate 302, and the horizontal support 303 form a storage cavity for placing blood bags; the first vertical mesh plate 301 is fixedly installed on the storage tray 203; several horizontal rods 304 are provided on the side of the second vertical mesh plate 302 near the first vertical mesh plate 301, the horizontal rods 304 are distributed around the second vertical mesh plate 302, and guide wheels 305 are provided at the ends of the horizontal rods 304 away from the second vertical mesh plate 302, the guide wheels 305 are slidably arranged in guide slides 306, the guide slides 306 are inclined, and an automatic lifting mechanism is also provided between the rotating disk 201 and the second vertical mesh plate 302, the automatic lifting mechanism is used to drive the second vertical mesh plate 302 to reciprocate up and down when the storage tray 203 rotates; a disinfection lamp 40 is installed on the inner wall of the device body 10 for virus inactivation treatment of the blood bags on the fixing mechanism 30.

[0036] Specifically, blood bags requiring virus inactivation are placed in several fixed mechanisms 30. Then, a drive mechanism drives a rotating disk 201 to rotate, which in turn drives several storage disks 203 to rotate. Simultaneously, the storage disks 203 also rotate under the action of a self-rotating mechanism. During the rotation, an automatic lifting mechanism drives a second vertical mesh plate 302 to move up and down. During this up-and-down movement, the second vertical mesh plate 302, under the action of guide wheels 305 and guide slides 306, intermittently moves closer to the first vertical mesh plate 301 to squeeze the blood bags, keeping the blood in the bags in a flowing state and ensuring that the blood in the bags is completely inactivated. At the same time, the blood bags not only revolve around the center of rotation of the rotating disk 201 but also rotate on their own axis, allowing the blood bags to be fully exposed to the disinfection lamp 40, effectively inactivating the virus. Meanwhile, the reciprocating squeezing of the blood bags by the second vertical mesh plate 302 effectively breaks up the ice fragments in the blood, facilitating subsequent processing.

[0037] like Figure 2 and Figure 5 As shown, in some embodiments, the driving mechanism includes a drive motor 202, which is fixedly mounted on the device body 10. The rotating disk 201 is connected to the drive motor 202 in a transmission manner, and the drive motor 202 provides power for the rotation of the rotating disk 201.

[0038] In some embodiments, the rotation mechanism includes an outer toothed ring 209 sleeved on the outside of the storage disk 203 and an inner toothed ring 212 meshing with the outer toothed ring 209. The inner toothed ring 212 is fixedly installed on the inner wall of the device body 10. Thus, when the rotating disk 201 rotates, the storage disk 203 rotates along with it, and the outer toothed ring 209 rotates under the action of the inner toothed ring 212.

[0039] In some embodiments, a support shaft 204 is provided at the center of the storage disk 203. The support shaft 204 is rotatably mounted on the rotating disk 201, and the support shaft 204 is arranged in a circumferential array on the rotating disk 201.

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the automatic lifting mechanism includes an abutment rod 307 fixedly installed at the bottom of the second vertical mesh plate 302 and a plurality of lifting protrusions 308 disposed on the rotating disk 201. The plurality of lifting protrusions 308 are arranged on the rotating disk 201 with the supporting rotating shaft 204 as the center. During rotation, the abutment rod 307 intermittently abuts against the lifting protrusions 308, causing the second vertical mesh plate 302 to move up and down, and approaching the first vertical mesh plate 301 during the movement. The two ends of the lifting protrusions 308 are slopes. Rolling balls are also rolled at the bottom of the abutment rod 307.

[0041] In some embodiments, a first ball is mounted at the bottom of the abutment rod 307, the first ball being used to abut against the rotating disk 201, thereby reducing resistance during operation.

[0042] In some embodiments, the bottom of the abutment rod 307 has a hemispherical groove, and a first rolling ball is disposed in the spherical groove.

[0043] In some embodiments, the guide slide 306 includes a body and an inclined slide groove disposed on the side wall of the body. The guide wheel 305 is rotatably disposed in the inclined slide groove. Thus, during the process of the second vertical mesh plate 302 driving the horizontal bar 304 to move up and down, the second vertical mesh plate 302 intermittently moves closer to the first vertical mesh plate 301 under the guidance of the inclined slide groove.

[0044] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, to facilitate the placement of blood bags between the first vertical mesh plate 301 and the second vertical mesh plate 302, the storage tray 203 includes a base plate 205 and a top plate 206. The center of the base plate 205 is fixedly sleeved on the support shaft 204, and the center of the top plate 206 is provided with a mounting through hole. The support shaft 204 passes through the mounting through hole, and there is an elastic element between the top plate 206 and the support shaft 204. The bottom of the first vertical mesh plate 301 is fixedly installed on the storage tray 203. The base plate 205 and the top plate 206 are also provided with a lifting mechanism. The distance between the first end of the guide slide 306 at the top and the first vertical mesh plate 301 is L1, and the distance between the second end of the guide slide 306 at the bottom and the first vertical mesh plate 301 is L2. L1 is greater than L2. In the initial state, under the action of the elastic element, the top plate 206 and the bottom plate 205 are close to each other. At this time, the guide wheel 305 is located at the first end of the guide slide 306. At this time, the distance between the second vertical mesh plate 302 and the rotating plate 201 is the largest, which makes it easy to place the blood bag between them. When the virus inactivation is stopped, the distance between them is also the largest, which makes it easy to remove the blood bag.

[0045] In some embodiments, the chassis 205 is provided with a first through hole 207, the top plate 206 is provided with a second through hole 208, and the abutting rod 307 passes through the second through hole 208 and the first through hole 207 and abuts against the top of the rotating disk 201.

[0046] In some embodiments, the lifting mechanism includes a plurality of mating rods 211 arrayed on the top of the chassis 205 and a plurality of mating arc-shaped protrusions 210 arrayed on the top plate 206. The number of mating arc-shaped protrusions 210 is equal to the number of mating rods 211, and the mating arc-shaped protrusions 210 are arranged on the trajectory of the mating rods 211.

[0047] In some embodiments, a torsion spring 213 is sleeved on the outer side of the support shaft 204. The two ends of the torsion spring 213 are respectively mounted on the top plate 206 and the sliding sleeve 214. The sliding sleeve 214 is slidably sleeved on the support shaft 204, so that the top plate 206 is elastically rotated and mounted on the support shaft 204.

[0048] In some embodiments, the inner side of the sliding sleeve 214 is symmetrically provided with sliding keys, which are slidably disposed in adjacent sliding grooves on the outer side of the support shaft 204, and the sliding grooves extend axially along the support shaft 204.

[0049] In some embodiments, the disinfection lamp 40 may be a methylene blue light lamp.

[0050] During use, the blood bags to be processed are placed between the first vertical mesh plate 301 and the second vertical mesh plate 302. Initially, the top plate 206 is in a lower position relative to 205, and the distance between the second vertical mesh plate 302 and the first vertical mesh plate 301 is large enough to place the blood bags. Then, the drive motor 202 drives the rotating disk 201 to rotate, and the disinfection lamp 40 is powered on. The base plate 205 rotates on its own axis while revolving around the central axis, under the action of the external gear ring 209 and the internal gear ring 212. At this time, under the action of the mating rod 211 and the mating arc-shaped protrusion 210... The top plate 206 moves upward relative to the bottom plate 205, which in turn moves the first vertical mesh plate 301 upward. This causes the second vertical mesh plate 302 to clamp the blood bag under its own weight and the weight of the medicine bag itself. Then, as the bottom plate 205 rotates, the contact rod 307 intermittently contacts the lifting protrusion 308, causing the second vertical mesh plate 302 to intermittently move closer to the first vertical mesh plate 301, intermittently squeezing the blood bag. This promotes blood flow and crushes the ice in the blood bag, accelerating the melting of the ice for subsequent processing.

[0051] Example 2

[0052] This embodiment also provides a method for virus inactivation, the method comprising: placing a blood bag into a fixing mechanism 30;

[0053] The drive mechanism drives the rotating disk 201 to rotate, and during the rotation of the rotating disk 201, the self-rotation mechanism drives the storage disk 203 to drive the blood bag in the fixing mechanism 30 to rotate.

[0054] Turn on the disinfection lamp 40 to inactivate the virus in the blood bag in the fixed mechanism 30.
