Sending mechanism and sample tube sending device

Abstract

The invention discloses a sending mechanism and a sample tube sending device and aims at solving the problem that hemolysis is prone to occurring in the sending process of an existing sample tube. The sending mechanism comprises a guiding body and an accelerating device. The guiding body is provided with a guiding channel so as to enable the sample tube to move in the guiding channel in a direction of the guiding channel, the acceleration device is used for providing an incremental transmission acceleration for the sample tube in the direction of the guiding channel, and the sending mechanism where the guiding body and the acceleration device are located is arranged in the sample tube sending device and used for sending the sample tube in the sample tube sending device. The sending mechanism and the sample tube sending device have the advantages that the sample tube is flexibly sent, so that the influence of the inertia effect of the sample tube and a blood sample self in the sample tube is weakened, the collision strength between the blood sample and the sample tube is weakened, and the hemolysis condition of the blood sample is avoided.

Description

technical field [0001] The invention relates to the technical field of medical material transmission, in particular to a sending mechanism and a sample tube sending device. Background technique [0002] At present, most of the samples in the clinical laboratory department come from different departments (wards) of the hospital. Due to the planning and layout of these departments (wards), they are often not on the same floor or in the same building as the laboratory department, which makes the transfer and transportation of samples unavoidable. At present, the single-tube pneumatic sample transmission system is widely used. This transmission system can not only effectively control the design cost, but also carry out cross-floor and cross-building transportation. However, single-tube pneumatic sample transmission systems generally exist. When the sample tube is sent, the initial transmission acceleration of the sample tube is too high, and the sample tube and the blood sample ...

Problems solved by technology

[0002] At present, most of the samples in the clinical laboratory department come from different departments (wards) of the hospital. Due to the layout of these departments (wards), they are often not on the same floor or in the same building as the laboratory department, which cannot avoid the transfer and transportation of samples.

At present, the single-tube pneumatic sample transmission system is widely used. This transmission system can not only effectively control the design cost, but also carry out cross-floor and cross-building transportation. However, single-tube pneumatic sample transmission systems generally exist. When the sample tube is sent, the initial transmission acceleration of the sample tube is too high, and the sample tube and the blood sample in the sample tube collide strongly under the action of inertia, which may easily lead to hemolysis of the blood sample
