Medical shaking device for blood collection tubes in test division

Abstract

The invention discloses a medical shaking device for blood collection tubes in a test division. The medical shaking device comprises fixing plates, a crankshaft, bushings, connecting rods, fixing cylinders and a motor, wherein a plurality of fixing plates are arranged at one side of the motor, a belt pulley I is arranged on one side of the motor, and a belt pulley II is arranged on one side of thebelt pulley I; the belt pulley I is connected with the belt pulley II through a belt I, the crankshaft is arranged on one side of the belt pulley II, and a plurality of journals are arranged on the crankshaft; the bushings are arranged on the journals, each connecting rod is arranged on one side of one bushing, and the other end of each connecting rod is provided with one corresponding fixing cylinder; the blood collection tubes are arranged inside the fixing cylinders, a belt pulley III is arranged on one side of the upper part of the belt pulley II, and the belt pulley III is fixedly connected with a position, above the belt pulley III, of the crankshaft; and the belt pulley II is connected with the belt pulley III through a belt II. According to the medical shaking device, the connecting rods are movably connected with the journals of the crankshaft through the bushings, and each fixing cylinder is arranged at the other end of one corresponding connecting rod, and when the blood collection tubes are placed in the fixing cylinders, the fixing cylinders are driven to move in a reciprocating linear mode through the rotation of the crankshaft so that even shaking of blood in the blood collection tubes can be achieved, the labor intensity of blood sampling personnel can be reduced, and the efficiency of blood collection can be improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a device for shaking blood collection tubes used in medical laboratories. Background technique [0002] In medical blood testing, various types of vacuum blood collection tubes generally need to be mixed on a mixing device after blood collection, so that the blood and the reagents reserved in the blood collection tubes can be mixed evenly, fully exerting the effectiveness of the reagents and promoting Various chemical reactions; traditional mixing generally uses manual hand-held blood collection tubes, and then shakes the blood collection tubes repeatedly, so that the auxiliary agent and blood in the tube can be mixed evenly, so that the blood can be effectively maintained. Although this is the simplest processing method, However, when the nursing staff has been carrying out frequent blood collection work, it is easy to make the nursing staff tired when shaking, such as a...

[0002] In medical blood testing, various types of vacuum blood collection tubes generally need to be mixed on a mixing device after blood collection, so that the blood and the reagents reserved in the blood collection tubes can be mixed evenly, fully exerting the effectiveness of the reagents and promoting Various chemical reactions; traditional mixing generally uses manual hand-held blood collection tubes, and then shakes the blood collection tubes repeatedly, so that the auxiliaries and blood in the tube can be mixed evenly, so that the blood can be effectively maintained. Although this is the simplest processing method, However, when the nursing staff has been carrying out frequent blood collection work, it is easy to make the nursing staff tired by shaking continuously, such as arm numbness, etc., which not only increases the labor intensity of the blood collection staff, but also reduces the blood collection efficiency of the blood collection staff.
