This invention belongs to the field of surgical instrument technology and discloses a disposable sterile specimen retrieval bag with spill prevention, comprising a cannula, a push rod, and a specimen bag. The push rod is slidably connected inside the cannula, and the specimen bag is connected to one end of the push rod. The specimen bag includes a support strap with several ratchet teeth on one side. One end of the support strap is connected to a buckle, and the buckle has protrusions that match the ratchet teeth. The other end of the support strap passes through the buckle. The support strap and the buckle form an elastic annular support ring. A hollow sleeve is fitted onto the annular support ring, with one end connected to the end of the support strap and the other end connected to the buckle. The hollow sleeve is connected to the retrieval bag body. This invention solves the technical problems of existing specimen bags having limited options for aperture specifications, being easily damaged, and having a semi-closed opening that hinders the smooth placement of specimens.

This application relates to a mobile phone securing cord structure and clothing, belonging to the field of clothing accessories technology. It includes: a cover plate, located in the pocket of the clothing and used to cover the pocket opening; and a securing cord, sewn in a wavy shape to the underside or edge of the cover plate, having multiple hook parts for flexible connection to a mobile phone case. This application connects the securing cord to the mobile phone case, allowing the phone to be placed directly in the pocket. This effectively connects the phone to the clothing body, whether during outdoor activities or when taking the phone out for use, effectively preventing the risk of the phone accidentally falling off or being lost. It is particularly suitable for use during strenuous outdoor activities and when using the phone at heights, preventing the phone from falling and improving the safety of carrying the phone while wearing clothing.

The application discloses a waistband structure, and belongs to the technical field of waistbands, which comprises a main band body and a sub-band body, the two ends of the main band body and the sub-band body are respectively and respectively detachably connected, the sub-band body is arranged near the middle position of the main band body and is used for gathering the main band body, and at least one adjusting part is formed by folding the main band body relative to the sub-band body, and a connecting piece for fixing the adjusting part is arranged on the outer wall of the main band body. The adjusting part is folded to make the main band body capable of being flexibly adjusted according to the body shape of a user, effectively avoiding that the top of the main band body presses or clamps the lower edge of the chest of the user, or that the bottom of the main band body rubs against the hip bone or the hip of the user to cause discomfort, and improving the size adaptability and ergonomics compatibility. The adjusting part can be fixedly installed on the outer wall of the main band body through the connecting piece, thereby preventing the adjusting part from being randomly rolled up and raised to cause discomfort to the user, and improving the wearing comfort of the user.
