This device is installed in the filtration system and enables automatic segmented heat sealing of the catheter after the blood bag device 10a completes the blood filtration process, thereby reducing the manpower required for heat sealing and improving heat sealing efficiency.

[0037] The blood filtration system in this embodiment filters blood using a suspended blood bag device 10a, such as... Figure 3 As shown, the blood bag device 10a includes a blood bag 11a, a catheter 12a, a whitening module 13a, and a collection bag 14a. The catheter 12a connects the blood bag 11a and the collection bag 14a, and the whitening module 13a is connected to the catheter 12a.

[0038] like Figures 1-3 As shown, the heat sealing device provided in this embodiment of the present invention includes a frame 10, a transposition module 20 and a heat sealing module 30. The heat sealing module 30 is slidably connected to the frame 10 along the height direction of the frame 10. The transposition module 20 is connected to the heat sealing module 30 and is used to drive the heat sealing module 30 to slide so that the heat sealing module 30 performs multi-point heat sealing on the conduit 12a.

[0039] Specifically, the heat sealing device consists of a frame 10, a transposition module 20, and a heat sealing module 30. The heat sealing module 30 is slidably connected to the frame 10 along its height. The transposition module 20 is connected to the heat sealing module 30. When heat sealing the conduit under the bleaching module 13a, the heat sealing module 30 can be driven by the transposition module 20 to heat seal multiple points of the conduit 12a from bottom to top. After heat sealing at each point of the conduit 12a, the conduit 12a can be disconnected at each heat sealing point. After the heat sealing point near the collection bag 14a is disconnected, a seal is formed on the collection bag 14a. After the other heat sealing points are disconnected, the conduit 12a can be divided into several segments containing bleached blood. The blood in each segment can be used as a sample for subsequent testing of the bleached blood. Therefore, through the automatic segmented heat sealing of this heat sealing device, multiple segments of bleached blood can be sampled while sealing the collection bag 14a, providing convenience for the subsequent processing of the bleached blood.

[0040] In one embodiment, such as Figure 1 and 3As shown, the rack 10 is provided with a slide rail 11 extending along the height direction of the rack 10, and the heat sealing module 30 is connected to the slide rail 11 through a sliding block.

[0041] It can be understood that the transposition module 20 can be any driving component such as a pneumatic cylinder or a hydraulic cylinder, which can drive the heat sealing module 30 to move up and down.

[0042] In one embodiment, as shown in Figure 1 and 3 The transposition module 20 includes a motor 21 and a lead screw 22, the lead screw 22 is rotationally connected to the rack 10 and extends towards the height direction of the rack 10, the motor 21 is fixed to the rack 10 and connected to the lead screw 22 for driving the lead screw 22 to rotate, and the heat sealing module 30 is threadedly connected to the lead screw 22 through a lead screw nut. Specifically, when performing the segmented heat sealing of the lower side conduit 12a of the white filter module 13a, the heat sealing module 30 first performs heat sealing on the heat sealing point close to the collection bag 14a, after completing the heat sealing of the point, the motor 21 drives the lead screw 22 to rotate, which can drive the heat sealing module 30 to move upwards along the lead screw 22, and then the heat sealing module 30 performs heat sealing on the adjacent heat sealing point above, until the heat sealing of all heat sealing points is completed.

[0043] It can be understood that the heat sealing module 30 can be any heat sealing device capable of realizing heat sealing of the conduit.

[0044] In one embodiment, as shown in Figures 1-3 The heat sealing module 30 includes a heat sealing fixed frame 31, a heat sealing driving member 32, a first heat supply block 33, and a second heat supply block 34, the heat sealing fixed frame 31 is slidably connected to the rack 10, the first heat supply block 33 is fixed to the heat sealing fixed frame 31, the second heat supply block 34 is oppositely arranged with the first heat supply block 33 and forms a heat sealing gap 35 with the first heat supply block 33, and the heat sealing driving member 32 is connected to the second heat supply block 34 for driving the second heat supply block 34 to move towards or away from the first heat supply block 33. Specifically, when performing the hanging of the blood bag device 10a, the conduit located at the lower side of the white filter module 13a is placed between the heat sealing gap 35, and when performing the heat sealing of the conduit 12a, the heat sealing driving member 32 drives the second heat supply block 34 to move towards the first heat supply block 33, so that the first heat supply block 33 and the second heat supply block 34 respectively perform heat sealing on the conduit 12a at both sides of the conduit 12a, and finally complete the heat sealing of the conduit 12a.

[0045] In one embodiment, the transposition module 20 is connected to the heat sealing fixed frame 31 for driving the heat sealing fixed frame 31 to slide.

[0046] In this embodiment, the heat sealing fixed frame 31 is slidably connected to the slide rail 11.

[0047] In this embodiment, the heat-sealing fixing frame 31 is provided with an installation cavity, and the heat-sealing driving component 32 is fixed in the installation cavity.

[0048] In one embodiment, such as Figures 1-3 As shown, a heat-sealing head 311 is provided at the end of the heat-sealing fixing frame 31, and the first heating block 33 and the second heating block 34 are both located inside the heat-sealing head 311. Specifically, with the above structure, the conduit 12a only needs to pass through the heat-sealing head 311 to achieve heat sealing of the conduit 12a. Therefore, when installing the blood bag device 10a, it is only necessary to pass the conduit 12a of the blood bag device 10a through the heat-sealing head 311, which facilitates the installation of the blood bag device 10a.

[0049] In one embodiment, such as Figures 1-3 As shown, a first insertion port 312 is provided on the side of the heat-sealing head 311. The first insertion port 312 is located on one side of the heat-sealing gap, allowing the conduit to enter the heat-sealing gap 35. Specifically, when installing the blood bag device 10a, it is only necessary to allow the conduit 12a under the filter module 13a to enter the heat-sealing gap 35 through the first insertion port 312 on the side of the heat-sealing head 311, thereby facilitating the installation of the blood bag device 10a.

[0050] In one embodiment, such as Figures 1-3 As shown, the heat sealing device also includes a guide head 40, which is fixed to the heat sealing bracket 31. The guide head 40 has a guide hole 41 with an opening on one side, and the guide hole 41 is collinear with the heat sealing gap 35, allowing the conduit 12a to pass through. Specifically, the guide head 40 can provide guidance for the conduit 12a and, during the heat sealing process, limit the conduit 12a on both the upper and lower sides of the heat sealing point, thereby improving the heat sealing quality of the conduit 12a.

[0051] In this embodiment, as Figures 1-3 As shown, there are two guide heads 40, which are located on the upper and lower sides of the heat sealing module 30, respectively.

[0052] In one embodiment, such as Figures 1-3 As shown, the end face of the guide head 40 is provided with a second through port 42, which is connected to the guide hole 41, allowing the guide tube 12a to enter the guide hole 41.

[0053] Specifically, when installing the blood bag device 10a, it is only necessary to allow the conduit 12a on the lower side of the filter module 13a to enter the guide hole 41 from the second through-hole 42 on the side of the heat-sealing head 311, thereby facilitating the installation of the blood bag device 10a.

[0054] In this embodiment, as Figures 1-3As shown, the first supply opening 312 and the second supply opening 42 are staggered by being arranged on the side of the heat sealing head 311 and the end face of the guide head 40 respectively, so that the first supply opening 312 and the second supply opening 42 can effectively prevent the catheter 12a from being separated from the heat sealing gap 35 and the guide hole 41.

[0055] In one of the embodiments, as shown, Figures 1-3 The heat sealing device further comprises a position sensor 50 fixed to the heat sealing fixing frame 31 and electrically connected with the motor 21. Specifically, since the heat sealing device mainly seals the catheter 12a from bottom to top, after the exhaust of the collection bag 14a is completed, the motor 21 drives the heat sealing module 30 to descend, and when the position sensor 50 senses the marked heat sealing position of the catheter 12a, the motor 21 stops driving the heat sealing module 30, and the heat sealing module 30 starts to seal the catheter 12a from bottom to top.

[0056] As shown, Figure 3 The utility model discloses further provide a filter white system, including heat sealing device. Specifically, the filter white system passes through the heat sealing device, realizes the automatic segmented heat sealing of the catheter 12a under the filter white module 13a through the heat sealing device, effectively alleviates the manpower required for the heat sealing of the catheter 12a, improves the heat sealing efficiency of the catheter 12a, can realize the multi -section sampling of the blood after filtering white while sealing the collection bag 14a, provides the convenience for the subsequent processing of the blood after filtering white.

[0057] As shown, Figure 3 The filter white system further comprises a hanging unit 60, a supporting unit 70 and a breaking unit 80. The hanging unit 60 and the supporting unit 70 are respectively arranged on the top and the bottom of the rack 10. The hanging unit 60 can hang the blood bag 11a of the blood bag device 10a, and the supporting unit 70 can support the collection bag 14a of the blood bag device 10a. When filtering white, the blood bag 11a filled with blood is hung on the hanging unit 60, and the air inlet valve 111a of the blood bag 11a is connected to the breaking unit 80, so that the installation of the blood bag device 10a on the filter white system is completed. After the installation of the blood bag device 10a is completed, the breaking unit 80 breaks the air inlet valve 111a on the blood bag 11a, so that the gas enters the inside of the blood bag 11a, and the blood flows from the blood bag 11a into the catheter 12a, then flows through the filter white module 13a, and then flows into the collection bag 14a after being filtered by the filter white module 13a. The blood filtered by the collection bag 14a is collected, the filtering white of the blood is completed, and after the filtering white is completed, the heat sealing device performs segmented heat sealing on the catheter 12a between the filter white module 13a and the collection bag 14a.

[0058] In order to better understand the utility model, the following will be combined with Figures 1 to 3The technical scheme of the utility model is explained in detail: before carrying out the white filtering work, the blood bag 11a filled with blood is hung on the hanging unit 60, and the air inlet valve 111a of the blood bag 11a is connected to the breaking unit 80, the conduit 12a between the white filtering module 13a and the collecting bag 14a enters the heat sealing gap 35 and the guide hole 41 from the first wear opening 312 and the second wear opening 42 respectively, after the installation of the blood bag device 10a is completed, the breaking unit 80 breaks the air inlet valve 111a on the blood bag 11a, so that the blood bag device 10a carries out the white filtering, after the white filtering of the blood is completed, the transposition module 20 drives the heat sealing module 30 to gradually rise, so that the heat sealing is from bottom to top on the multiple points of the conduit 12a, and then the conduit 12a between the white filtering module 13a and the collecting bag 14a is segmented heat sealed, the manpower required for the heat sealing of the conduit 12a is significantly reduced, and the heat sealing efficiency of the conduit 12a is improved.

[0059] The specific embodiment of the utility model described above does not constitute the limitation of the protection scope of the utility model.
