Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical inspection instruments, in particular to a new Westergren erythrocyte sedimentation rate rack. Background Art
[0002] The erythrocyte sedimentation rate (ESR) is the speed at which red blood cells sediment naturally under certain conditions in a laboratory. The whole blood anticoagulated with sodium citrate is statically placed in a small vertical glass tube. Since the specific gravity of red blood cells is relatively large, they naturally sink under the action of gravity. Under normal circumstances, the sinking is very slow. The distance that the erythrocyte sedimentation tube sinks from the start of erection to 1 hour is recorded to represent the sedimentation speed of red blood cells, which is called ESR.
[0003] (1) Currently, for the iron erythrocyte sedimentation rate rack using the traditional manual method, after sucking the mixed anticoagulated blood with a glass erythrocyte sedimentation tube, the fixed spring device at the top is pulled up to fix the top of the erythrocyte sedimentation tube, and the bottom is placed on a rubber pad to vertically fix the erythrocyte sedimentation tube. The result is observed after one hour. However, this device has many drawbacks. First, the reserved space of the top spring device is limited, and the rubber soft pad at the bottom of the rack is very thin. Often during operation, the blood specimen at the bottom will ooze out, resulting in non-standard measurement and inaccurate results. Second, the metal support rods on both sides and the screws at the top often become loose, easily causing the erythrocyte sedimentation tube to tilt and not be completely vertical. Third, the erythrocyte sedimentation rate racks are all single-row, with two types of 5 positions and 10 positions. The detection volume is relatively small. When the specimen volume is large, the erythrocyte sedimentation tubes need to be cleaned and disinfected multiple times. During the cleaning process, the glass erythrocyte sedimentation tubes are easy to break and hurt people, and are also easy to be not cleaned thoroughly, resulting in cross-contamination. (2) Some companies produce slender erythrocyte sedimentation tubes with black caps. After blood collection, they are directly placed on a special erythrocyte sedimentation rate detector for detection, which also has drawbacks. First, it is very difficult to mix evenly during blood collection, and the inspection department often receives coagulated specimens. Second, the inner diameter of this kind of erythrocyte sedimentation tube is thicker than that of the standard Westergren erythrocyte sedimentation tube, and the result is not as satisfactory as the standard erythrocyte sedimentation tube. Third, an additional erythrocyte sedimentation rate instrument needs to be purchased, and the cost is significantly increased. Therefore, it is extremely urgent to invent a new Westergren erythrocyte sedimentation rate rack to solve the above problems. Summary of the Invention
[0004] The utility model provides a new Westergren erythrocyte sedimentation rate rack, which has a simple structure and low cost, and can solve a series of problems existing in the prior art. To achieve this purpose, the utility model adopts the following technical solutions.
[0005] This new Westergren erythrocyte sedimentation rate rack is a cube, including:
[0006] A base;
[0007] There is an adjusting screw for adjusting the height at each of the four corners under the base; a vertical upright support plate and two layers of horizontal support plates are arranged on each of the two sides and the back above the base; there is an 18 cm long scale with a 0 scale on the front section of the vertical upright support plates on both sides above the base, which is convenient for measuring the height of the descent of red blood cells; 50 fixed holes with a diameter of 5 mm are punched on each layer of the horizontal support plate, and the fixed holes on the top layer of the horizontal support plate are numbered from 1 to 50, with a spirit level in the middle; there are hole grooves with a diameter of 5 mm corresponding to the fixing holes of the horizontal support plates on the base, and the depth of the hole grooves is half the thickness of the base.
[0008] Furthermore, the erythrocyte sedimentation tube used in the novel erythrocyte sedimentation rack is a hollow hard translucent PE plastic tube with an inner diameter of 2.5 mm, an outer diameter of 4 mm, and a length of 230 mm, and there is a scale line 30 mm away from one end of the plastic tube.
[0009] The beneficial effects of the utility model are as follows:
[0010] (1) The vertical support plate is perpendicular to the base, and the two layers of horizontal support plates are placed in the middle and the top. The overall shape is a rectangular parallelepiped, making the entire ESR rack firm and not easy to shake and move; and the ESR rack is not completely closed, and is made of materials such as stainless steel, copper, alloy, acrylic and plastic that are resistant to disinfectants, which brings convenience to disinfection and cleaning. (2) The fixing holes on the base and the two layers of horizontal support plates are aligned one by one, which can ensure that the ESR tube is in a vertical state; (3) The bottom of the ESR tube is sealed with plasticine to prevent the blood sample from leaking.
