Description

Automatic production device for blood smear

technical field

The invention relates to the field of medical devices, in particular to an automatic production device for blood smears.

Background technique

The smear is generally made by first using a pipette to sample and drop it on a glass slide, then push the sample away with a clean pusher, and stain it after the sample is dry. However, this method is only suitable for the production of a single or a few smears and is more common in clinical practice. However, using this production method for blood smears, considering the large workload and low efficiency of manual smear production, when the detection workload is large, this manual smear production method also greatly reduces the detection efficiency. , it is difficult to meet the detection requirements.

The conveyor belt is driven to move; the drip tube, the pusher, the drying tube and the dyeing tube are arranged in sequence along the movement direction of the conveyor belt. There are several placing plates at intervals on the conveyor belt. The height of the side wall in the direction is equal to the sum of the height of the placing plate and the slide, the height of the side wall of the baffle parallel to the moving direction of the conveyor belt is greater than the sum of the height of the placing plate and the slide, the baffle is fixed with the conveyor belt, and the placing plate and the baffle The plates are slidably connected, and a sliding bar is vertically fixed at the bottom of the placing plate, and the sliding bar vertically penetrates the conveyor belt and is slidably connected to the conveyor belt; the drip tube and the dyeing tube are arranged vertically; the pusher, the drip tube, the drying tube and the dyeing tube are located above the placement board.

The transfer unit in this scheme can transfer the slides, so that the slides can automatically pass through the dropper, pusher, drying tube and staining tube, without the need to manually pick up the slides for smearing, staining and other operations. , to improve the production efficiency of blood smears.

2. There is a drying tube, which can guide the drying gas. After the drying gas is blown out from the lower end of the drying tube, the air flow around the glass slide can be accelerated, thereby reducing the humidity around the glass slide and promoting the coating on the glass slide. The moisture in the sample evaporates, thereby accelerating the drying speed of the sample and further improving the production efficiency of the blood smear.

3. The upper end of the annular baffle is higher than the placing plate, so the baffle acts as a limit for the inserted glass slide, preventing the slide glass from sliding off the placing plate, thereby preventing the slide glass from being damaged.

4. There is a sliding bar under the placing plate. Push the sliding bar upwards to make the placing plate slide upward relative to the baffle, so that the slide slides up to the top of the baffle, and the removal of the slide will not be blocked by the baffle. , it is more convenient to take out.

When the placing plate 7 continues to move to the right, the first quick connector 41 and the second quick connector 64 rotate and separate from each other. When the first quick connector 41 and the second quick connector 64 are staggered, the first quick connector 41 and the second The quick joint 64 is reset under the action of the first torsion spring and the second torsion spring, and the guide rod 65 is reset under the action of the upper sliding spring 66 .
