[0018] This application proposes a device for detecting the volume of blood bags. The device includes a housing, a drive assembly, and a sample bag. The housing has a receiving groove and a partition, which divides the receiving groove into a storage groove and an overflow groove. The partition is located below the opening of the receiving groove, allowing the storage groove and the overflow groove to communicate. The sample bag is positioned on the output end of the drive assembly, causing it to reciprocate linearly along the depth of the storage groove under the drive assembly's direction. Therefore, when the sample bag is submerged in the storage groove and the liquid sample in the sample bag is at the same level as the liquid in the storage groove, the volume of liquid overflowing from the storage groove and flowing into the overflow groove is the volume of the liquid sample in the sample bag, based on Archimedes' principle. This effectively improves the accuracy and convenience of detecting the volume of the liquid sample in the sample bag, avoiding the technical problem of inaccurate blood sample volume in existing technologies, which affects product quality.

[0034] like Figure 1 As shown, an embodiment of this application provides a device 100 for detecting the volume of a blood bag. The device 100 for detecting the volume of a blood bag includes a housing 110, a drive assembly 120, and a sample bag.
[0035] The housing 110 has a receiving groove 111 and a partition 112, which divides the receiving groove 111 into a liquid storage groove 1111 and an overflow groove 1112. The partition 112 is located below the opening of the receiving groove 111, so that the liquid storage groove 1111 and the overflow groove 1112 are in communication. The sample bag is disposed on the output end of the drive assembly 120, which drives the sample bag to reciprocate linearly along the depth direction of the liquid storage groove 1111.
[0036] The device 100 for detecting the volume of blood bags provided in this application embodiment places the sample bag on the output end of the driving component 120, so that under the driving action of the driving component 120, the sample bag moves back and forth linearly along the depth direction of the liquid storage tank 1111 in sync with the output end of the driving component 120. Therefore, when the sample bag is submerged in the liquid storage tank 1111 and the liquid sample in the sample bag is at the same level as the liquid in the liquid storage tank 1111, the volume of liquid overflowing from the liquid storage tank 1111 and flowing into the overflow tank 1112 is the volume of the liquid sample in the sample bag, utilizing Archimedes' principle. This effectively improves the accuracy and convenience of detecting the volume of the liquid sample in the sample bag, avoiding the technical problem of inaccurate blood sample volume in blood bags in the prior art, which affects product quality.
[0037] For example, the drive assembly 120 can be a reciprocating linear motion mechanism such as a linear drive motor, cylinder, or hydraulic cylinder. The sample bag can be a blood bag, and the liquid sample can be a blood sample.
[0038] like Figure 1 As shown, in one embodiment of this application, the device 100 for detecting the volume of the blood bag further includes a first detection sensor 130, which is disposed on the side wall of the housing 110 and flush with the top wall of the partition 112, for detecting the light transmittance of the sample bag.
[0039] In this embodiment, a first detection sensor 130, flush with the top wall of the partition 112, is installed on the side wall of the housing 110 to detect the light transmittance of the sample bag. Thus, when the liquid sample in the sample bag is above the liquid in the storage tank 1111, the first detection sensor 130 detects low light transmittance of the sample bag, and the drive assembly 120 continues to drive the sample bag toward the bottom of the storage tank 1111.
[0040] When the liquid sample in the sample bag is at the same level as the liquid in the storage tank 1111, the first detection sensor 130 detects that the light transmittance of the sample bag is high, and controls the drive assembly 120 to stop driving the sample bag to move. This ensures the accuracy of detecting the volume of the liquid sample in the sample bag.
[0041] For example, the first detection sensor 130 may be a red or blue light detector.
[0042] like Figure 1 As shown in the above embodiments of this application, the device 100 for detecting the volume of blood bags further includes a control panel 140, which is disposed on the side wall of the housing 110 and electrically connected to the first detection sensor 130 and the drive assembly 120 respectively.
[0043] In this embodiment, a control panel 140 is provided on the side wall of the housing 110, which is electrically connected to the first detection sensor 130 and the drive assembly 120 respectively. Thus, when the liquid sample in the sample bag is above the liquid in the storage tank 1111, the first detection sensor 130 detects that the light transmittance of the sample bag is low and feeds back a low light transmittance signal to the control panel 140. The control panel 140 can then control the drive assembly 120 to continue automatically driving the sample bag towards the bottom of the storage tank 1111 based on this signal.
[0044] When the liquid sample in the sample bag is at the same level as the liquid in the storage tank 1111, the first detection sensor 130 detects that the light transmittance of the sample bag is high and feeds back the signal of high light transmittance to the control panel 140. The control panel 140 can control the drive component 120 to automatically stop driving the sample bag to move according to the signal.
[0045] like Figure 1 As shown, in any of the above embodiments of this application, the device 100 for detecting the volume of blood bags further includes a support member 150, which is connected to the output end of the drive assembly 120, and the sample bag is disposed on the support member 150.
[0046] In this embodiment, by connecting the support member 150 to the output end of the drive component 120 and placing the sample bag on the support member 150, the support member 150 can synchronously and stably reciprocate linearly along the depth direction of the liquid storage tank 1111, following the output end of the drive component 120, thereby driving the sample bag placed on the support member 150 to synchronously and stably reciprocate linearly along the depth direction of the liquid storage tank 1111.
[0047] like Figure 1 As shown in the above embodiments of this application, the device 100 for detecting the volume of blood bags further includes a clamping assembly 160, which is disposed on the support member 150 and used to clamp or release the sample bag. Thus, the clamping assembly 160 allows the sample bag to be easily fixed to or removed from the support member 150, ensuring the stability, ease of installation, and ease of disassembly of the sample bag.
[0048] In the above embodiments of this application, the clamping assembly 160 includes a first clamping member, a second clamping member, a rotating member, and an elastic member. The first clamping member is rotatably connected to the second clamping member through the rotating member. The elastic member is sleeved on the rotating member and abuts against the first clamping member and the second clamping member respectively.
[0049] In this embodiment, the first clamping member is rotatably connected to the second clamping member via a rotating member, and an elastic member is sleeved on the rotating member and abuts against both the first and second clamping members. Thus, when the sample bag needs to be clamped, the elastic member drives the first and second clamping members to move closer together, thereby clamping the sample bag. When the sample bag needs to be released, the operator uses external force to resist the elastic force of the elastic member, causing the first and second clamping members to move away from each other, thereby releasing the sample bag.
[0050] For example, the rotating component can be a hinge shaft, and the elastic component can be a torsion spring.
[0051] like Figure 1As shown in the above embodiments of this application, two drive components 120 are provided, and the two drive components 120 are respectively located on two opposite sides of the receiving groove 111. The support member 150 is connected to the output ends of the two drive components 120 respectively. In this way, the support member 150 can be driven to move smoothly back and forth in a linear motion along the depth direction of the liquid storage groove 1111, thereby driving the sample bag to move smoothly back and forth in a linear motion along the depth direction of the liquid storage groove 1111.
