Closed blood and bone marrow pushing device

Abstract

The invention discloses a closed blood and bone marrow pushing device. The device comprises an operation chamber and guide rails, the operation chamber is an open box body, vertical walls in the leftside and the right side of the open box body are kept parallel, the symmetrical guide rails are arranged on the inner side faces of the vertical walls on the left side and the right side, and a support capable of clamping a sample push piece to keep a fixed angle and sliding along the guide rails is arranged between the guide rails. The blood and bone marrow smear pushing device has the advantagesthat blood and bone marrow smears are prepared in the closed operation chamber, air and operators can be prevented from pollution caused by blood and bone marrow sample aerosol, the prepared blood and bone marrow smears are uniform in thickness, later observation and analysis are better facilitated, and non-laboratory doctors and non-hematology doctors can operate the device easily. The device has the characteristics of improving the preparation quality of blood and bone marrow smears and improving the clinical operation efficiency.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a closed blood and bone marrow pusher. Background technique [0002] Image analysis of peripheral blood cells and bone marrow is a commonly used diagnostic technique for blood diseases and various diseases. It is suitable for the diagnosis and identification of various blood diseases. Slices are also called smears. The method for preparing a smear in the prior art is to first drop a peripheral blood or bone marrow sample on a glass slide with a syringe, and then use a glass sample pusher to smear the peripheral blood or bone marrow sample on the glass slide to make a smear. This operation has the following disadvantages: first, due to the different technical proficiency of the operators in preparing smears, the quality of the smears produced varies, which will affect the accuracy of the test and clinical diagnosis; It is easy to damage or contaminate the sample during t...

Problems solved by technology

This operation has the following disadvantages: first, due to the different technical proficiency of the operators in preparing smears, the quality of the smears produced varies, which will affect the accuracy of the test and clinical diagnosis; It is easy to damage or contaminate the sample during the process; third, the peripheral blood or bone marrow is directly exposed to the air during smear preparation, which is easy to generate aerosols, especially when dealing with samples from patients with highly infectious diseases such as new coronavirus pneumonia. Cause infection of medical staff; Fourth, medical staff hold glass products for smear preparation, which can easily lead to accidental scratch accidents
