AI Technical Summary
Existing techniques for separating semen solids in assisted reproductive technologies, such as gradient centrifugation, suffer from several drawbacks. These include insufficient structural design, potential physical damage to sperm, high sperm loss rates, complex procedures, and lengthy processing times.
A separation brush for separating solid matter in semen during assisted reproductive technology is designed. The brush uses parallel comb teeth that are staggered and fixed to the bottom of the brush body to form a multi-layered fence-like structure. Solid-liquid separation is achieved through the multi-layered combination of the two comb teeth. The precise design of the comb tooth spacing ensures effective interception of solid matter and reduces clogging. The combination of a hand handle and clamping mechanism simplifies the operation process.
It effectively intercepts unliquefied solids and flocculent matter, reduces sperm loss, improves sperm recovery rate, simplifies operation procedures, enhances processing efficiency and success rate, and meets clinical operation standards.

Description
TECHNICAL FIELD
[0001] The utility model belongs to semen processing tool technical field, especially relate to a separation brush for separating semen solid in assisted reproductive technology. BACKGROUND
[0002] Semen processing is one of the key steps in assisted reproductive technology (ART), and its purpose is to separate high-quality sperm with good activity for further in vitro fertilization or microinjection operation. In the current experiment and clinical practice, gradient centrifugation method is the main method of semen separation. However, due to incomplete liquefaction of semen of some patients, undegraded gelatinous solid or flocculent material may remain in the liquefied semen. These solids can significantly affect the layering effect and sperm recovery rate of subsequent gradient centrifugation.
[0003] Chinese patent with publication number CN204219887U discloses a special mesh screen for density gradient centrifugation of liquefied abnormal semen. The upper part of the mesh screen is a filter part in a cylindrical structure, and a filter screen is arranged inside the filter part. The filter screen is composed of two identical filter plates stacked on each other, and the relative position between the two filter plates is adjusted by a pore size adjusting knob arranged outside the filter part. The lower part of the mesh screen is a drainage part, and the upper end of the drainage part is connected with the bottom of the filter part. The opening of the lower end of the drainage part gradually narrows to one side and forms a drainage port at the bottom. A drainage tube is connected below the drainage port. However, this special mesh screen for density gradient centrifugation of liquefied abnormal semen has deficiencies in structure design, semen processing effect, and operation convenience. First, the structure may cause physical damage to sperm by gravity screening, thereby affecting the activity and function of sperm. Second, the use of multiple layers of filter membranes may cause loss of part of the sperm during the filtering process, and the sperm concentration is low, which may affect the subsequent application effect. In addition, the screening and separation process of this method takes a long time, which may reduce the processing efficiency of the system, especially when processing a large number of samples.
[0004] Therefore, a separation brush for separating semen solid in assisted reproductive technology is proposed. UTILITY MODEL CONTENT
