Description

A device for measuring erythrocyte sedimentation rate

technical field

The utility model relates to a sedimentation rate measuring device, in particular to a red blood cell sedimentation rate measuring device, which belongs to the field of biotechnology.

Background technique

Although the specific gravity of erythrocytes is greater than that of plasma, it settles slowly under normal circumstances, indicating that erythrocytes can be relatively stable suspended in plasma. This characteristic of erythrocytes is called suspension stability. The sedimentation speed of red blood cells is usually expressed by the distance that red blood cells sink at the end of the first hour, which is called the erythrocyte sedimentation rate. Usually, changes in plasma components will cause erythrocytes to cascade and increase their sedimentation rate. For example, when the content of plasma fibrin, globulin and cholesterol increases, the erythrocyte sedimentation rate will increase.

The traditional method of measuring erythrocyte sedimentation rate is to inhale the negative pressure of blood into the Wechsler ESR tube by washing the ear ball, put the lower end on the rubber pad of the ESR rack, and press the white metal sheet on the top of the ESR rack to make the Wechsler ESR tube The lower end is tightly combined with the rubber pad to prevent blood from leaking out and to make the Wechsler ESR tube stand upright and fixed on the ESR rack. It is easy to suck blood directly into the ear washing ball, causing contamination of the ear washing ball, and the ear washing ball is not easy to be cleaned. At the same time, the position of the blood level in the Wechsler tube is not fixed, the experimental results are not easy to read directly, and there are errors in the results. The low-end rubber pads of the frame are also easily stained by blood, difficult to clean, and prone to aging, resulting in blood leakage from the erythrocyte sedimentation tube during the experiment, which consumes more blood and requires too many devices.

The utility model achieves the above object through the following technical solutions: a device for measuring erythrocyte sedimentation rate, including a rubber bag, a measuring tube ball, a rubber pad, a measuring tube, a scale scale, a sponge pad, a supporting ring, a supporting rod, a windshield and Anti-slip mat; the bottom of the rubber bag is connected with a measuring tube ball, and a rubber pad is arranged under the measuring tube ball, and the measuring tube ball is tightly connected with the measuring tube downward to form an integral body, and the side of the measuring tube is provided with a scale Scale, the top of the support rod is a sponge pad, the sponge pad is fixed on the upper surface of the support ring, the two sides of the support ring are respectively connected downward to the support rod, and the bottom of the support rod is connected to the windshield , the bottom of the windshield is provided with a non-slip pad.

Further, in order to achieve the purpose of avoiding negative blood pressure being sucked into the capsule, the volume of the rubber capsule is smaller than the volume of the measuring tube connected to it.

Further, in order to achieve the purpose of effective support, the ball diameter of the measuring tube ball is larger than the ring diameter of the support ring.

Further, in order to prevent the blood level from fluctuating due to the flow of wind when standing still, when the measuring tube is inserted into the support frame, the bottom end of the measuring tube is lower than the upper edge of the windshield and does not touch the support frame bottom of.

Further, in order to achieve the purpose of effectively replacing accessories and generating negative pressure without affecting the experimental results, the rubber bladder is detachably connected to the top of the measuring tube bulb, and the connection is tight and airtight.

Further, in order to achieve better reading and measurement effects, the zero scale line of the scale scale is at the middle position.

The beneficial effects of the utility model are: the device is compact in structure, easy to use, and reasonable in design, can test the sedimentation rate of red blood cells at the analysis site with a small amount of blood, can reduce the error of the measurement result, and effectively improve the accuracy of the test. At the same time, the device is easy to clean and has stable working performance. The device is equipped with a measuring tube ball, which can prevent the negative pressure of blood from being sucked into the capsule. The suction keeps the blood in the tube, which is clean and hygienic. The device consists of only two parts, which is simple, light, easy to clean, easy to prepare for experiments, and suitable for popularization and use.
