The utility model provides a wearable device capable of preventing urine leakage and used for nuclear medicine imaging examination. The wearable device is composed of a protective pad and a wearable structure. The protective pad comprises a waterproof bottom layer and a water-absorbing surface layer; the wearing structure is of a T-shaped structure and is composed of a wearing body, a left wing and a right wing, the two ends of the outer side of the lower edge of the wearable body are connected with the inner sides of the left wing and the right wing through first pasting areas. The rear part of the wearable structure is connected with the upper surface of the water-absorbing surface layer through a second pasting area; drawing structures are arranged at the upper end and the lower end of the protective pad and penetrated by drawing ropes. The radioactive urine absorption device can basically absorb radioactive urine overflowing from all examinees, so that the examination bed board is prevented from being subjected to radioactive contamination, radioactive secondary pollution can be prevented from being generated when a polluted wearing device is treated, and the structure of the radioactive urine absorption device is easy to disassemble and replace and convenient to use.

This utility model relates to the field of personal care products technology, specifically a front-flow design structure for disposable diapers to prevent soiling. It includes a diaper body and an elastic barrier band structure positioned on the inner absorbent layer of the diaper body. The elastic barrier band structure starts from the outer side of one waist, extends through the groin area on the same side to the perineum, and then extends to the outer side of the other waist. This utility model, by setting the elastic barrier band structure in a three-dimensional "∞" shape, can divide the interior of the diaper body into independent rear and front areas. This innovative design effectively prevents feces and other stains from overflowing from the rear area to the front, avoiding the soiling spread problem common in traditional diapers. For example, during use by infants or adults, when excrement accumulates in the rear area, the elastic barrier band structure acts as a barrier.

The utility model provides a kind of line arrangement frame of IBE ion beam etching equipment, line arrangement frame includes first layer board, second layer board sequentially arranged from bottom to top;First layer board is equipped with liquid supply component;Second layer board is equipped with gas supply component, realize the complete isolation of liquid path and gas path in space, even if liquid leakage, also can not permeate gas path, significantly reduce cross contamination and security risk;While liquid inlet chamber and liquid outlet chamber are respectively connected to processing chamber equipment by manual ball valve parallel liquid supply and liquid return;With liquid flow detection meter, it can ensure that each chamber obtains stable, uniform process liquid, improve temperature control and etching uniformity;Compressed air component, nitrogen component are gathered by valve island, and the output end of valve island is respectively connected to each pneumatic actuating mechanism, to realize one-stop piping;Only need to operate at valve island when fault or maintenance, without disassembling one by one, can greatly shorten downtime.

The utility model discloses a novel antifouling film. The novel antifouling film comprises a rolled film body and an antifouling base layer, winding drums are inserted into the inner wall of the roll film body, spiral threads are formed in the left and right sides of the outer walls of the winding drums, and sleeves are installed on the left and right sides of the outer walls of the two winding drums through the spiral threads in a threaded mode. According to the utility model, the protective paper of the antifouling film is directly torn off for use by adopting a back adhesive technology instead of a back adhesive paper technology, the installation operation is convenient, and the oil-proof bonding layer is made of PVC (Polyvinyl Chloride) resin, so that the antifouling film is non-toxic and harmless, has excellent oil repellency and waterproofness and cannot permeate stains, thereby enhancing the waterproofness and moisture resistance of the film; by arranging the silicone oil and the oil-proof additive, the surface of the fireproof and oil-proof film is smoother and convenient to clean, and the adhesive is prepared from vinyl acetate, so that the fireproof and oil-proof film has good high-temperature resistance and chemical resistance, and the adhesion firmness and the adhesion covering rate between the fireproof and oil-proof film and a wall are enhanced; and therefore, the peeling phenomenon of the antifouling film is also prevented.

The utility model relates to the field of acrylic resin production, and discloses a quantitative feeding and mixing machine for acrylic resin production, which comprises two feeding barrels, a mixing box and a feeding cylinder, a piston is slidably and hermetically arranged in each feeding barrel, the feeding cylinder is mounted at the right end of each feeding barrel, and the mixing box is mounted in the feeding barrel. A push rod of each feeding air cylinder slidably penetrates through the right side of the corresponding feeding barrel to be connected with a piston, the mixing box is arranged in the middle of the lower portion of the two feeding barrels, the left ends of the feeding barrels communicate with the interior of the mixing box through discharging pipes, and a discharging pipe is arranged below the right end of the mixing box; the two feeding barrels are arranged above the mixing box, the push rod of the feeding air cylinder slides into the feeding barrels and is provided with the piston, the piston enables materials to be quantitatively added into the mixing box under the action of the feeding air cylinder, the piston can retract, and follow-up material adding is also facilitated.
