[0010] In order to realize the rotation of the rotating rod, threaded columns are fixed on the outer sides of the two supporting legs of the rotating rod, and threaded grooves matching the threaded columns are opened on the side of the L-shaped rod.

[0011] In order to realize the installation and disassembly of the scraper, a slot is opened on the lower side of the bottom rod of the rotating rod, and the scraper is inserted into the slot. A bolt is screwed on the side of the bottom rod of the rotating rod, and the bolt head extends into the slot and presses against the surface of the scraper.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] See also Figure 1-4 The utility model provides a blood smear apparatus, comprising a smear table 1, a U-shaped baffle 2 is fixed to the top of the smear table 1 near one end thereof, a glass sheet M is placed inside the baffle 2, a support frame is slidably mounted on the top of the smear table 1, and a plurality of fixing structures arranged at equal intervals for fixing a scraper N are mounted on the support member, and a cleaning structure is provided near the other end of the smear table 1.

[0021] In order to realize the sliding of the support frame, two symmetrically arranged guide rods 3 are fixed on the top of the smear table 1 along its length direction. The interface of the guide rods 3 is an inverted trapezoid. Slide sleeves 4 are slidably installed on the guide rods 3, and the support frame is installed on the two slide sleeves 4.

[0022] Specifically in the present invention, the support frame includes two symmetrically arranged L-shaped rods 5, the legs of the L-shaped rods 5 are fixed to the top of the sliding sleeve 4, the top rods of the two L-shaped rods 5 face the same direction, and each fixing structure is installed between the top rods of the two L-shaped rods 5.

[0023] Specifically, in the present invention, the fixing structure includes a U-shaped rotating rod 6 , two legs of the rotating rod 6 are rotatably mounted between the top rods of the two L-shaped rods 5 , and the scraper N is detachably mounted on the bottom rod of the rotating rod 6 .

[0024] In order to realize the rotation of the rotating rod 6, threaded columns 7 are fixed on the outer sides of the two supporting legs of the rotating rod 6, and threaded grooves matching the threaded columns 7 are opened on the side of the L-shaped rod 5. This design enables the rotating rod 6 to have movement stability after rotation. Although the rotating rod 6 has a certain movement, it does not affect its normal use.

[0025] In order to realize the installation and disassembly of the scraper N, a slot 6-1 is opened on the lower side of the bottom rod of the rotating rod 6, and the scraper N is inserted into the slot 6-1. A bolt 8 is screwed on the side of the bottom rod of the rotating rod 6, and the bolt head of the bolt 8 extends into the slot 6-1 and presses against the surface of the scraper N.

[0026] In order to clean the scraper N, the cleaning structure includes a water pool 9 arranged at the bottom of the smear table 1 near the other end thereof. The water pool 9 is located between the two guide rods 3. The pool mouth of the water pool 9 extends upward to the top of the smear table 1. A partition 10 is fixed in the middle of the bottom of the water pool 9.

[0027] The working principle of the present invention is described in detail below: the partition 10 divides the water pool 9 into two water storage spaces, and an electric heating tube is installed in a water storage space close to the glass sheet M to heat the water therein. The bolt 8 is unscrewed from the rotating rod 6, and the scraper N can be placed in the slot 6-1. The bolt 8 is then screwed onto the rotating rod 6 until the bolt head of the bolt 8 is tightly against the scraper N to lock the scraper N. The rotating rod 6 is rotated to tilt the scraper N against the glass sheet M, and the support frame is pushed to drive the sliding sleeve 4 to slide along the guide rod 3, thereby driving the scraper N to move on the glass sheet M to scrape the blood. After completion, the support frame is continued to be pushed to push the used scraper N to the top of the water storage space with the electric heating tube, and the rotating rod 6 is rotated downward to make the scraper N vertical. Arrangement, so that the scraper N is extended into the water, the electric heating tube is connected to the external film and started, the water is boiled, and soap can be put into the water to melt until the scraper N is boiled for twenty minutes. During this process, the smeared glass piece M can be taken down and replaced with a new glass piece M, or a new scraper N can be installed on the rotating rod 6. When the scraper N is boiled, the rotating rod 6 is rotated upward to make the scraper N extend out of the water storage space with the electric heating tube, and the support frame is continued to be pushed to drive the boiled scraper N to move above the water storage space without the electric heating tube, and then the boiled scraper N is flushed with water through the external faucet to achieve thorough cleaning. In this way, the entire device can be convenient for disassembling and assembling the scraper N and the glass piece M, and also for cleaning other scrapers N, thereby improving efficiency.

[0028] Finally, the most important contribution of the present invention is that the support frame can drive the scraper N to pass over the glass sheet M to scrape off the blood on the glass sheet M, and the scraper N after use can directly enter the pool 9 for cleaning, which is more convenient.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
