Technical Field

[0001] The invention belongs to the field of blood separation, and in particular relates to a line sensor for detecting blood cells. Background Art

[0002] Blood is composed of plasma and blood cells. Among them, plasma, as one of the important components of blood, contains many biologically active substances, such as proteins, coagulation factors, immune factors, etc. These substances have a wide range of application value in clinical treatment. Separating and collecting plasma can better utilize blood resources, improve treatment effects, reduce the occurrence of transfusion reactions, and also prepare biological products to meet the needs of clinical treatment.

[0003] Plasma separation is generally performed using centrifugal blood separation equipment. During the centrifugation process, different blood components will form different layers due to different physical properties such as density, size, and shape. In the process of transferring plasma to the plasma collector, blood cells may enter with it. In order to prevent blood cells from entering the plasma collection bag and ensure the quality of plasma, it is necessary to monitor and identify the blood cell components in the plasma pipeline. Summary of the invention

[0004] The purpose of the present invention is to provide a line sensor for detecting blood cells, which is used to distinguish between plasma and blood cells. During the plasma separation and collection process, it monitors whether blood cells flow into the plasma collection bag in the plasma pipeline and outputs the monitoring information to the plasma separation equipment.

[0005] To achieve the above purpose, the technical solution of the present invention is a line sensor for detecting blood cells, comprising: a shell, an upper cover assembly and a lower base assembly; the shell is installed on the upper cover assembly, and the upper cover assembly is fixed on the lower base assembly.

[0006] Preferably, the upper surface of the shell is provided with ridges to facilitate opening the shell; pipe entry and exit slots are left at the lower edges on the left and right sides of the shell; and mounting holes are provided on the left and right side surfaces of the shell.

[0010] Preferably, the upper surface of the lower base assembly has clamping attachments.

[0011] Preferably, the bottom surface of the lower base assembly has a wiring terminal opening.

[0012] The beneficial effects of the present invention are as follows: the line sensor for detecting blood cells can be fixed on the blood separation device, and the plasma pipeline can be conveniently and quickly clamped in the line sensor for detecting blood cells. The monitoring signal can be output to the control circuit interface of the blood separation device through the bottom port. This design has a compact structure, a simple and compact appearance, saves space, and is easy to install. At the same time, it is simple to use and operate, saves time and effort, has high work efficiency, and has great market promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are intended to explain the present invention rather than to limit it.

[0018] like Figure 1 and Figure 2 As shown, a line sensor for detecting blood cells includes a shell 1, an upper cover assembly 2 and a lower base assembly 3; the shell 1 is hinged to the upper cover assembly 2 at the mounting holes on the left and right sides by connecting shafts, and the shell 1 can be opened and buckled. When opened, a plasma pipeline can be placed, and when buckled, the plasma pipeline can be fixed; the upper cover assembly 2 is fixed to the lower base assembly 3 by screws.

[0019] A ridge 3-1 is provided on the upper surface of the shell 1. When the shell 3 is pushed upward from the ridge 3-1, the shell 3 can be easily opened; there are bayonet holes 3-2 for pipeline entry and exit at the lower edges on the left and right sides of the shell 3. When the shell 3 is closed, the bayonet holes 3-2 can clamp the plasma pipeline in place.

[0020] An upper PCB board is installed in the upper cover assembly 2, and the upper PCB board can provide and adjust the detection light source.

[0021] A lower PCB board is installed in the lower base assembly 3, and the lower PCB board can collect, process and output signals of the detection light passing through the plasma pipeline.

[0022] There is a placement table 3-2 on the upper surface of the lower base assembly 3. During operation, the part of the plasma pipeline to be detected is placed on the placement table 3-2 to receive the transmission of the detection light source.

[0023] The upper surface of the lower base assembly 3 is provided with a clamping accessory 3-1. When in operation, the clamping accessory 3-1 clamps the plasma pipeline together with the buckled shell 1, which plays a good clamping and fixing role on the detected part of the plasma pipeline.

[0024] The bottom surface of the lower base assembly 3 has a wiring terminal opening, through which the detection signal is output and connected to the control circuit interface of the blood separation device.
