TECHNICAL FIELD

[0001] The utility model relates to blood filtration technical field, concretely relates to sub - bag elevating gear. BACKGROUND

[0002] Blood transfusion is an important rescue and treatment measure in clinic, and can rescue the life of patient, but also can cause harm to patient. Modern blood transfusion requires removing white blood cells to ensure blood transfusion safety. The white blood cell filtration of blood bag needs to be executed through the blood bag system of blood bag and collection bag.

[0003] The patent document with the announcement number CN502554575U discloses a blood bag system, which comprises a catheter, a blood inlet part, a filter, a clamping part, a blood recovery bag and a bypass flow path. The catheter is used for blood passing. The blood inlet part is arranged at the upper end of the catheter. The blood recovery bag is arranged at the lower end of the catheter. The filter is arranged in the catheter and can remove white blood cells from blood. The blood inlet part is used for filtering white blood cells from the blood flowing to the blood recovery bag. The bypass flow path is connected with the catheter and bypasses the filter. The clamping part is arranged in the catheter and the bypass flow path.

[0033] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail by combining with the drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0034] In order to solve the technical problem of low white blood filtration efficiency caused by the high position of the blood recovery bag in the white blood filtration system in the prior art, the utility model provides a sub-bag lifting device, which is arranged in the white blood filtration system, provides support for the collection bag of the blood bag device hung by the white blood filtration system, and can adjust the height of the collection bag, thereby improving the white blood filtration efficiency of blood.

[0035] The white blood filtration system of the embodiment filters white blood by hanging the blood bag device 10a, as shown in the figure. Figure 2 The blood bag device 10a includes a blood bag 11a, a catheter 12a, a white blood filtration module 13a, and a collection bag 14a.

[0036] Please refer to Figures 1-3 The sub-bag lifting device of the embodiment includes a rack 10, a bag body support frame 20, and a lifting driving unit 30.

[0037] Specifically, the sub-bag lifting device is provided with the rack 10, the bag body support frame 20, and the lifting driving unit 30. The bag body support frame 20 is slidably connected to the rack 10 and can support the collection bag 14a. The lifting driving unit 30 is connected to the bag body support frame 20 and can drive the bag body support frame 20 to slide, thereby adjusting the height of the bag body support frame 20. After the collection bag 14a is placed in the bag body support frame 20, the lifting driving unit 30 drives the bag body support frame 20 to descend, thereby lowering the ground level of the collection bag 14a on the bag body support frame 20 and increasing the distance between the collection bag 14a and the blood bag 11a, thereby speeding up the delivery of blood and improving the white blood filtration efficiency.

[0038] In the embodiment, the bag body support frame 20 is slidably connected to the bottom of the rack 10.

[0039] In one of the embodiments, as shown in the figure, Figures 1-3 The rack 10 is provided with a guide rod 12 extending in the height direction of the rack 10. Specifically, the guide rod 12 can limit and guide the sliding of the bag body support frame 20, thereby improving the stability of the sliding of the bag body support frame 20.

[0040] In one of the embodiments, as shown in the figure, Figures 1-3As shown, the bag body support frame 20 is provided with a sliding frame 23 and a sliding sleeve 24, the sliding frame 23 is fixed to the bag body support frame 20, and the sliding sleeve 24 is fixed to the sliding frame 23 and sleeved with the guide rod 12. Specifically, the bag body support frame 20 can be slidably connected with the guide rod 12 through the sliding sleeve 24.

[0041] In some embodiments, as shown in Figure 2 As shown, the sliding frame 23 is connected with the bag body support frame 20 through a first reinforcing rib plate 231. Specifically, the first reinforcing rib plate 231 can strengthen the strength of the sliding frame 23, thereby preventing the sliding frame 23 from deforming.

[0042] In one of the embodiments, as shown in Figures 1-3 The bag body support frame 20 is further provided with a limiting frame 25, and the limiting frame 25 is sleeved with the guide rod 12. Specifically, the limiting frame 25 can further limit the bag body support frame 20, thereby improving the stability of the bag body support frame 20.

[0043] In some embodiments, as shown in Figure 2 The limiting frame 25 is connected with the bag body support frame 20 through a second reinforcing rib plate 251. Specifically, the second reinforcing rib plate 251 can strengthen the strength of the limiting frame 25, thereby preventing the limiting frame 25 from deforming.

[0044] In one of the embodiments, as shown in Figures 1-3 The bag body support frame 20 is provided with a bag outlet on the side. Specifically, the bag outlet can facilitate the disassembly of the offspring.

[0045] In this embodiment, the lead screw nut of the bag body support frame 20 is fixed to the limiting frame 25.

[0046] In one of the embodiments, as shown in Figures 1-3 The bag body support frame 20 is provided with a containing cavity 21, and the containing cavity 21 is open on the upper side for containing the collection bag 14a. Specifically, the collection bag 14a can be placed in the containing cavity 21 through the opening on the upper side of the containing cavity 21, thereby ensuring the stability of the collection bag 14a and spacing the adjacent collection bags 14a to avoid mutual interference during the white filter work.

[0047] In one of the embodiments, the bag body support frame 20 is provided in several groups, and each bag body support frame 20 is arranged side by side. Specifically, the height of each bag body support frame 20 can be adjusted according to the length of the guide pipe 12a on the lower side of the white filter module 13a. After the installation of each collection bag 14a on the bag body support frame 20, the lifting driving unit 30 drives each bag body support frame 20 to descend, so that the guide pipe 12a on the lower side of the white filter module 13a is straightened or the bag body support frame 20 is lowered to the lowest position.

[0048] In one of the embodiments, as shown in Figures 1-3As shown, the sub-bag lifting device further comprises a gravity sensing module 40 fixed to the bag body support frame 20 and electrically connected with the lifting driving unit 30, for hanging the collecting bag 14a and sensing the gravity of the collecting bag 14a, so as to drive the lifting driving unit 30 to drive the bag body support frame 20 to descend when the collecting bag 14a is hung. Specifically, after the collecting bag 14a is hung on the gravity sensing module 40, the gravity sensing module 40 senses the gravity of the collecting bag 14a, and after sensing the gravity of the collecting bag 14a, the gravity sensing module 40 transmits the sensed gravity signal to the controller, so that the controller controls the lifting driving unit 30 to drive the bag body support frame 20 to descend, thereby increasing the distance between the collecting bag 14a and the blood bag 11a and accelerating the white blood cell filtration.

[0049] In the embodiment, since the lengths of the conduits 12a of the blood bag devices 10a are different, in a normal case, after the installation of the collecting bag 14a is completed, the lifting driving unit 30 drives the bag body support frame 20 to descend to the lowest position. However, compared with the blood bag devices 10a with relatively short conduits 12a, if the gravity sensor senses that the gravity of the collecting bag 14a decreases during the process of the lifting driving unit 30 controlling the bag body support frame 20 to descend, it indicates that the conduit 12a has been straightened, so that the collecting bag 14a cannot be lowered any more. At this time, the controller controls the lifting driving unit 30 to stop driving the bag body support frame 20, and finally the collecting bag 14a is lowered as much as possible.

[0050] In the embodiment, after the blood flows into the collecting bag 14a, the gravity of the collecting bag 14a gradually increases. When the gravity sensor 45 detects that the gravity of the collecting bag 14a reaches a certain value, the controller controls the lifting driving unit 30 to drive the bag body support frame 20 to ascend, so as to lift the collecting bag 14a, and then the staff member can take out the collecting bag 14a filled with blood by slightly bending over, thereby reducing the labor consumed by taking out the collecting bag 14a and improving the efficiency of taking out the collecting bag 14a.

[0051] In the embodiment, as shown, Figures 1-3 Specifically, the top of the collecting bag 14a can be hung on the hanging rod 41 of the sensing module, and the bottom of the collecting bag 14a is supported by the bag body support frame 20, so as to stabilize the collecting bag 14a and facilitate the gravity sensing module 40 to sense the gravity of the collecting bag 14a.

[0052] It can be understood that the lifting driving unit 30 can be any driving component that can drive the bag body support frame 20 to slide, such as a pneumatic cylinder, a hydraulic cylinder, etc.

[0053] In one of the embodiments, as shown, Figures 1-3As shown, the lifting driving unit 30 comprises a motor 31 and a screw rod 32, the screw rod 32 is rotationally connected to the rack 10 and extends towards the height direction of the rack 10, the motor 31 is fixed to the rack 10 and connected with the screw rod 32, for driving the screw rod 32 to rotate, the bag body support frame 20 is threadedly connected to the screw rod 32 through a screw nut. Specifically, when adjusting the height direction of the bag body support frame 20, the motor 31 drives the screw rod 32 to rotate, so as to drive the bag body support frame 20 to move along the axial direction of the screw rod 32, thereby realizing the adjustment of the height direction of the bag body support frame 20 and ensuring the stability of the bag body support frame 20 during sliding.

[0054] In one embodiment, as shown in the drawings, Figures 1-3 The bottom of the rack 10 is provided with a sliding rail 11 extending towards the height direction of the rack 10, and the bag body support frame 20 is provided with a sliding block 22, and the bag body support frame 20 is slidably connected to the sliding rail 11 through the sliding block 22. Specifically, through the connection of the sliding block 22 and the sliding rail 11, the stability between the bag body support frame 20 and the rack 10 can be improved, so as to ensure the stable sliding of the bag body support frame 20 along the height direction of the rack 10.

[0055] As shown in the drawings, Figure 1 The utility model embodiment further provides a white blood filtering system, which comprises a sub-bag lifting device. Specifically, the white blood filtering system can filter white blood through the blood bag device 10a, and the white blood filtering system collects the bag 14a on the bag body support frame 20, and drives the bag body support frame 20 to descend through the lifting driving unit 30, so as to lower the terrain of the collecting bag 14a on the bag body support frame 20, widen the distance between the collecting bag 14a and the blood bag 11a, and thus accelerate the blood delivery speed and improve the white blood filtering efficiency.

[0056] In the embodiment, as shown in the drawings, Figure 3 The white blood filtering system further comprises a hanging unit 50, a clamping unit, an exhaust unit and a heat sealing unit, the hanging unit 50 is arranged on the top of the rack 10, the clamping unit is used for clamping the catheter 12a or the bypass pipe 15a, the exhaust unit is used for exhausting the collecting bag 14a, and the heat sealing unit is used for heat sealing the catheter 12a.

[0057] Specifically, when the blood filtration is performed, the clamping unit clamps the bypass pipe 15a to prevent the blood from bypassing the filtration module 13a and flowing out of the bypass pipe 15a into the collection bag 14a. After all the blood in the blood bag 11a is filtered by the filtration module 13a and enters the collection bag 14a, the clamping unit clamps the catheter 12a due to the remaining air in the collection bag 14a. At this time, the exhaust unit exhausts the gas in the collection bag 14a, and the gas is discharged through the bypass pipe 15a and enters the empty blood bag 11a. Thus, the exhaust of the collection bag 14a is realized. After the exhaust of the collection bag 14a is completed, the heat sealing unit heat seals the catheter 12a connected to the collection bag 14a, so that the collection bag 14a can be sealed. Finally, the catheter 12a is pulled off from the heat sealing point, so that the collection bag 14a can be separated from the blood bag device 10a, and the blood filtration is completed.

[0058] In order to better understand the present application, the following will be combined Figures 1 to 3 The technical scheme of the present application will be described in detail. Before the blood filtration is performed, the blood bag of the blood bag device 10a is hung on the hanging unit 50, and the collection bag 14a is hung on the gravity sensing module 40. After the gravity sensing module 40 senses the gravity of the collection bag 14a, the lifting driving unit 30 drives the bag body support frame 20 to descend, and then the blood filtration is performed. During the filtration, the air inlet valve 111a of the blood bag 11a is first broken, and the clamping unit clamps the bypass pipe 15a. After all the blood in the blood bag 11a is filtered by the filtration module 13a and enters the collection bag 14a, the gravity sensor 45 detects that the gravity of the collection bag 14a increases, the lifting driving unit 30 drives the bag body support frame 20 to rise and lift the collection bag 14a, the exhaust unit exhausts the collection bag 14a, and the heat sealing unit heat seals the catheter 12a connected to the collection bag 14a. Finally, the blood filtration is completed.
