The present invention discloses a nail polish bottle with sustainable oil supply, belonging to the technical field of nail art equipment. A nail polish bottle with sustainable oil supply includes a bottle body and a bottle cap, the end of the bottle body is connected to a liquid outlet pipe, the liquid outlet pipe is densely covered with a plurality of through holes, the end of the liquid outlet pipe is also densely covered with bristles, a push plate is installed in the bottle cap, a sealing ring is sleeved on the outer side of the push plate, the sealing ring is in frictional contact with the inner wall of the bottle body, and a pushing mechanism is also installed on one side of the bottle body. The technical solution of the present application pushes out the nail polish by the sealing ring and the push plate through the cooperation between the sealing ring arranged on the outer side of the push plate and the pushing mechanism on one side of the bottle body, and the sealing ring can push the nail polish adhered to the inner wall of the bottle body toward the direction of the liquid outlet pipe, which enables the user to make full use of the nail polish in the bottle body and effectively avoid waste.

The utility model discloses a two-channel nasal oxygen cannula relates to nasal oxygen cannula technical field, the two-channel nasal oxygen cannula includes nasal oxygen cannula body, also includes: the humidification mechanism, the humidification mechanism includes fixed nasal oxygen cannula body end portion humidification box, the inside of humidification box is filled with distilled water, the front side of humidification box is communicated with air supply pipe, the air supply pipe is communicated with the nasal oxygen cannula body end portion. A wet curtain and a water pump which are used for humidifying oxygen are respectively fixed in the humidifying box, a water pipe is fixed on the side surface of the humidifying box, a flow dividing box used for dispersing water flow is fixed on the humidifying box, and the water pipe is respectively communicated with the water pump and the flow dividing box. According to the nasal oxygen cannula, due to the arrangement of the humidifying mechanism, oxygen enters the humidifying mechanism through the air supply pipe, passing oxygen flow is humidified through the wet curtain in the humidifying mechanism, the humidified oxygen flow is conveyed into the nasal cavity of a user through the nasal oxygen cannula body, an airway of the nasal cavity is prevented from being dried, and discomfort during oxygen therapy is reduced.

The application discloses an engineering marker pen and belongs to the technical field of marker pens. The engineering marker pen comprises a shell, a fixing seat is fixedly connected to the inner wall of the shell, a pen barrel vertically and slidably arranged in the fixing seat, and a first thread is arranged on the bottom end inner wall of the shell. The engineering marker pen is characterized in that: the connecting plate is rotated counterclockwise and clockwise, the fourth thread is rotated clockwise or counterclockwise in the third thread, the gap between the connecting plate and the cap gradually increases or decreases, the pushing plate is subjected to the extrusion force of the bottom surface of the cap, the extrusion force of the pushing plate increases or decreases, the shrinkage or extension of the protection plate is controlled, the protection plate is retracted into the slot when the marker pen is used, the protection plate is extended from the slot after the use of the marker pen, the protection plate and the shell form a sealed cavity, the pen end of the pen barrel is prevented from being exposed to the air and dried, the marker pen can be continuously used, the waste of the marker pen is avoided, and the use cost of the marker pen is reduced.

An introducer tool for use with a vascular access channel system and method is provided. The aspiration catheter is pre-assembled into the expanded proximal section of the introducer tool when the radially self-expanding distal section of the aspiration catheter is in a radially uncompressed state. The introducer tool and a suction catheter pre-assembled in the introducer tool together are guided as a single unit into the hemostasis valve and the tapered guide sheath luer taper. The suction catheter is pushed through the introducer tool. The radially self-expanding distal section of the aspiration catheter is radially compressed so as to be receivable in the lumen of the guide sheath catheter when passed through the lumen of the shaft of the introducer tool and / or the compression section of the tapered inner profile of the tapered guide sheath luer taper. When the radially self-expanding distal section is radially compressed, the aspiration catheter slides into the lumen of the guide sheath catheter.
