Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a small slide rinser. Background Technique

[0002] At present, the main staining methods for bone marrow and peripheral blood morphological smear staining at home and abroad are Wright staining and Wright-Giemsa staining. The staining steps of the two are basically the same. The specific staining steps are mainly as follows: Place the dried bone marrow or peripheral blood smear slide flat on the staining rack, and perform fixation, staining, rinsing and drying respectively. Among them, the rinsing step takes a long time and requires the operator to control the size of the water flow: first, use a small water flow to gently float the dye and slowly rinse off most of the staining solution and its sediment, and then turn to a large water flow to quickly rinse off the remaining staining solution. This step mainly relies on manually controlling the water flow rate of the laboratory faucet at present. The advantages are that the requirements for laboratory hardware are simple and the operation is convenient, but the current disadvantages are as follows: 1. At present, the width of the slides on the market is about 25 mm, and the water flow from the faucet is relatively thin, which easily causes uneven stress on the slides during rinsing. The position with greater stress is prone to blood film shedding, while the position with smaller stress has dye residues due to insufficient rinsing; 2. Due to the different proficiency levels of operators and the mastery of water flow rates, the final rinsing effects between different laboratories or different operators are different, ultimately affecting the staining effect.

A first diversion cavity 124 is formed between the lower layer orifice plate 122 and the upper layer plate 121, and a second diversion cavity 125 is formed between the upper layer plate 121 and the upper inner end of the spray head shell 11. The inner diameter of the extension pipe 123 is smaller than the hole diameter on the lower layer orifice plate 122.

[0018] Specifically, the pulling conversion valve 2 includes a valve shell 21, the valve shell 21 is fixedly connected to the upper end of the spray head shell 11, a first diversion pipe 22 and a second diversion pipe 23 are fixedly connected inside the valve shell 21.

The second diversion pipe 23 penetrates through the spray head shell 11 and is communicated with the second diversion cavity 125. The upper end of the first diversion pipe 22 is higher than the upper end of the second diversion pipe 23, and through holes 24 are penetrated through the outer side walls of the first diversion pipe 22 and the second diversion pipe 23. Sealing rubber rings 25 are fixedly connected to both sides of the outer side walls of the first diversion pipe 22 and the second diversion pipe 23 where the through holes 24 are located.

[0019] Specifically, the water volume regulating valve 3 includes a ball valve housing 31 integrally formed with the upper end of the regulating nozzle 27.

[0020] Working principle: When the utility model is in use, the outer end of the connecting flexible water pipe 4 is connected to the faucet in the laboratory. During use, according to the amount of water used, rotate the ball valve core 32, and adjust the water volume according to the cooperation between the pointer 34 and the scale plate 33.

At this time, the through hole 24 on the first diversion pipe 22 will enter the regulating nozzle 27, and the upper end of the second diversion pipe 23 will enter the socket hole 29 and be blocked. At this time, the water flow will flow into the first diversion cavity 124 from the first diversion pipe 22 and spray out from the lower layer orifice plate 122. At this time, the glass slide is flushed with a large amount of water. Therefore, the utility model can conveniently control the water flow rate, and at the same time can realize visual adjustment of the water flow, increasing the success rate of glass slide flushing. At the same time, using a conversion spray head increases the flushing area, avoiding uneven stress during glass slide flushing: the blood film is prone to fall off at the position with greater stress, while dye residues remain due to insufficient flushing at the position with smaller stress.
