Sample analyzer and its manual injection assembly

Abstract

The invention discloses a sample analyzer and a manual sample injection assembly thereof. The manual sample injection assembly comprises: a manual sample setting seat, which is provided with a sample setting hole for receiving a tube to be tested manually placed; a first driving part, The manual sample setting seat is driven to rotate between its initial position and the second sample setting position of the sample analyzer along the rotation path of the XY plane; the second driving member drives the manual sample setting seat along the Y direction with a preferential injection path in the second Move between the sample setting position and the first sample setting position of the sample analyzer; wherein, the second sample setting position and the first sample setting position are set back and forth along the Y direction, and the second sample setting position is on the front side of the sample analyzer; manual When the sample setting seat is in the initial position, the position of the sample setting hole deviates from the connection line between the first sample setting position and the second sample setting position. In the present invention, when the sample is detected, the user can start the emergency detection mode at any time, and manually inject the sample. The module manually injects samples into the emergency tube to be tested without waiting, avoiding the risk of contamination of emergency samples.

Description

technical field [0001] The invention relates to the technical field of sample detection, in particular to a sample analyzer and a manual sample injection assembly thereof. Background technique [0002] The sample analyzer is the most commonly used blood cell analyzer, which uses reagents to perform statistical analysis on various cells in blood samples, such as red blood cells, white blood cells, platelets, hemoglobin, etc., to provide a basis for the diagnosis and treatment of diseases. [0003] With the increasing degree of automation, more and more analyzers adopt the automatic batch injection mode. The user places the test tubes on the test tube rack, and the test tube rack transports the test tubes to the sample setting position of the analyzer in batches. The sample position grabs the test tube for detection, which can effectively reduce the user's operation and speed up the detection speed. However, in the automatic batch sampling mode, the sample tubes can only be t...

Problems solved by technology

However, in the automatic batch sampling mode, the sample tubes can only be tested one by one in order, which is not suitable for some emergency tubes that need to be treated first. Therefore, some analyzers are also equipped with a manual sampling mode. The test tube is manually placed in the sample setting position

[0004] However, in actual operation, when placing the emergency test tube manually, the test tube holder is often occupied by the test tube being tested, and the user needs to wait for the entire detection process of the test tube to be completed before putting in the emergency test tube, which not only wastes time, but also increases RISK OF CONTAMINATION OF ED SAMPLES

In addition, the existing products also have open sampling, which requires the sampling needle to extend out of the casing, and the user manually places the emergency sample under the sampling needle for sampling, which not only increases the risk of accidental stabbing for medical staff, but also if the patient of the samples carried the virus, also increasing the risk of aerosol infection
