This utility model belongs to the field of evidence extraction technology and discloses a device for extracting combustion accelerants from combustion residues. It includes a base plate, on which a water bath heating chamber, a vacuum suction device, and a controller are mounted. A sealed chamber is installed inside the water bath heating chamber. A one-way air inlet valve is located at the end of an air inlet pipe on one side of the sealed chamber, and a one-way exhaust valve on the other side of the sealed chamber is connected to the vacuum suction device via a flexible hose. An activated carbon filter is installed in a filter assembly located in the middle of the flexible hose. Water bath heating ensures more uniform heating of the sealed chamber, which is beneficial for the decomposition of combustion accelerants in the combustion residues. The vacuum suction device reduces the air pressure inside the sealed chamber, lowers the volatilization and decomposition temperature of the combustion accelerant, and increases the extraction rate of the device. Under the action of the vacuum suction device, substances volatilized from the residues are discharged from the sealed chamber and adsorbed by the activated carbon filter, thereby collecting more combustion accelerant substances and making the extraction effect of the device more ideal.

A device for introducing a VAC therapy sponge into an area of interest comprises a porous polyurethane sponge 1 for aspirating pathological secretion through an organ cavity, and a drainage tube 2, the sponge 1 being fastened to the end of the drainage tube 2. The device is characterized in that it further comprises a flexible metal guide wire 3 mounted in the drainage tube 2, a silicon tube 4 intended to encompass the compressed sponge 1, and a thread 5 compressing the sponge, said thread 5 having a knot 6 thereon which self-releases when the end 7 of the thread is pulled. The invention makes it possible to position a VAC therapy sponge in an area of interest when treating a gastrointestinal anastomotic leak using a vacuum aspirator system, while assuring compression of the entire sponge.

The invention provides a fetal head vacuum aspirator which comprises a near-end handle, a far-end suction cup and a traction component, and the traction component pulls the suction cup from the handle so as to provide auxiliary traction in the delivery process. The proximal handle includes a distal end portion that reciprocatingly receives a proximal end portion, where the distal end portion defines a neck that interfaces the traction member. A shoulder adjacent the neck provides a gripping surface for gripping relative to an index finger. The handle is manually and repeatedly pressed to operate the mechanical pump, and the mechanical pump generates suction force in the suction cup through the pneumatic pipe. A dynamometer in the handle is provided with a haptic protrusion extending through the shoulder, providing haptic force feedback to monitor the applied tension. The aspirator may also include a bending point marker on the traction member that enables precise alignment of the suction cup with a fetal bending point and monitoring of traction progression.
