Abstract

A high-reliability cell detector, including a machine body ( 4 ) and a blood cell detector installed on the top of the machine body ( 4 ). The blood cell detector includes a vascular frame ( 1 ) installed on the top surface of the machine body ( 4 ), with a U-shaped tube orifice ( 2 ) at the top of the vascular frame ( 1 ), and the inner wall of the U-shaped tube orifice ( 2 ) is embedded with a transmissive photo sensor ( 3 ), which includes a light emitter and a light receiver. By installing a blood cell detector on the top of the blood plasma collection machine, the transfusion tube can be clamped at the top of the blood cell detector, allowing the blood cell detector to detect in real-time whether there are blood cells in the transfusion tube. The blood cell detector has high recognition accuracy, high reliability, and strong resistance to bubble interference. By embedding an electromagnetic suction cup ( 5 ) at the bottom of the blood cell detector, the installation position of the blood cell detector can be flexibly adjusted according to actual usage.

Description

TECHNICAL FIELD The present disclosure belongs to the technical field of auxiliary devices for blood plasma collection machines, specifically relating to a high-reliability cell detector. BACKGROUND ART A blood plasma collection machine is a machine that uses the principle of centrifugation to collect blood plasma. It mainly consists of a centrifuge, display, machine body, liquid pump, and other components. It can quickly complete the collection of blood plasma. It can be used not only for the collection of raw material blood plasma for the production of blood products by blood product companies but also for the collection of fresh frozen plasma, with broad practicality. Existing blood plasma collection machines, when in use, transport external blood to the inside of the plasma collection machine through a transfusion tube. Existing plasma collection machines do not have the function to detect blood within the transfusion tube, which can inconvenience operators in determining whether there is blood in the transfusion tube. Therefore, this disclosure proposes a high-reliability cell detector. SUMMARY OF THE DISCLOSURE The purpose of this disclosure is to provide a high-reliability cell detector to solve the problems mentioned in the background technology. To achieve the above objectives, the present disclosure provides the following technical solutions: a high-reliability cell detector, including a machine body and a blood cell detector installed on the top of the machine body. The blood cell detector includes a vascular frame installed on the top surface of the machine body, with a U-shaped tube orifice at the top of the vascular frame. The inner wall of the U-shaped tube orifice is embedded with a transmissive photo sensor, which includes a light emitter and a light receiver, and the light emitter and light receiver are respectively embedded in the inner walls on both sides of the U-shaped tube orifice. Preferably, the bottom surface of the vascular frame is provided with a circular mounting groove, and an electromagnetic suction cup is embedded within the circular mounting groove. The surface of the electromagnetic suction cup is equipped with a connecting wire, which passes to the outside of the vascular frame. The electromagnetic suction cup is magnetically connected to the top surface of the machine body. Preferably, L-shaped side slots are symmetrically provided on both side surfaces of the vascular frame. An L-shaped block is arranged inside the L-shaped side slot, and a limit card head is fixed at the bottom end of the L-shaped block. Limit card slots are provided on both side surfaces of the electromagnetic suction cup, and the end of the limit card head penetrates to the inside of the limit card slot. Preferably, a rectangular slot is provided on one inner wall of the L-shaped side slot, and a spring and a side slider are arranged inside the rectangular slot. The side slider is fixed to the top end of the L-shaped block. Preferably, a protruding rod is fixed to one side surface of the L-shaped block, and a rotating pull block is rotatably mounted at the end of the protruding rod. Preferably, base pads are installed on the inner walls on both sides of the U-shaped tube orifice, opposite the top of the transmissive photo sensor, and the surface of the base pad is provided with strip protrusions. Preferably, the base pad and the strip protrusion are of an integrated structure, and the cross-section of the strip protrusion is semi-circular. Compared with the Existing Technology, the Beneficial Effects of the Disclosure are: 1. By installing a blood cell detector on the top of the blood plasma collection machine, the transfusion tube can be clamped at the top of the blood cell detector, allowing the blood cell detector to detect in real-time whether there are blood cells in the transfusion tube. The blood cell detector has high recognition accuracy, high reliability, and strong resistance to bubble interference.2. By embedding an electromagnetic suction cup at the bottom of the blood cell detector, the installation position of the blood cell detector can be flexibly adjusted according to actual usage, greatly improving the flexibility of the blood cell detector, and the electromagnetic suction cup is easy to install and remove.3. By setting the base pad and strip protrusion, a good limiting effect can be achieved for the transfusion tube entering the inside of the U-shaped tube orifice, thus improving the stability of the use of the blood cell detector.
