The invention discloses a brain-like tissue in-vitro printing and culture system and a brain-like tissue in-vitro printing and culture method. The system comprises a printing and culture module and a control module, wherein the printing and culture module comprises a mechanical hand, a printing spray head box, printing spray heads, a mobile platform and a liquid slot; the control module comprises a computer, a signal acquirer and a control box. According to the brain-like tissue in-vitro printing and culture system disclosed by the invention, an in-vitro brain tissue constructing method which is integrated with printing and culture functions can be used for increasing a survival rate of nerve cells in a printing process and later-stage tissue, preventing the interferences of environmental changes to printed brain-like tissue in a process of transferring to the culture system form the printing system, keeping the integral activity and the function construction of the tissue, the printing spray heads are combined with the mechanical hand to realize hybrid printing of various bracket materials and various cells, and a brain-like tissue gradient structure with a special function is conveniently constructed according to a relationship between each area structure of the brain tissue and the functions; the printing and culture device is provided with culture conditions for brain tissue in-vitro regeneration and a detecting device, and can be used for performing functional evaluation in a process of promoting the brain-like tissue to form.

The invention discloses a garbage bag which comprises a bag body. The opening of the bag body is provided with an opening, the upper edge of the front side wall of the bag body is below the upper edgeof the rear side wall of the bag body, the rear side surface of the front side wall of the bag body is above the rear side wall of the bag body, and the rear side surface of the rear side wall of thebag body is used for being detachably connected with a device for opening the opening in the top of the bag body. The invention also discloses a garbage can comprising the garbage bag and a garbage sorting treatment device. According to the garbage bag, the garbage can and the garbage sorting treatment device, the garbage bag in the garbage can is capable of being automatically replaced, and thelabor is saved favorably.

The invention discloses a urine detection device. The device comprises an overflow bucket, an urine inlet tube, a first urine discharging tube, a second urine discharging tube, a syringe pump and a urine sucking needle; the overflow bucket is provided with an upward opening, and is also provided with an overflow hole; the overflow bucket is connected with the urine inlet tube; the bottom of the overflow bucket is connected with a pollution discharging tube through the first urine discharging tube; the overflow hole is connected with the pollution discharging tube through the second urine discharging tube; the first urine discharging tube is provided with a valve; the syringe pump is fixedly connected to a base, and is connected with the urine syringe needle through a flexible tube; and theurine sucking needle and the overflow bucket relatively move in a perpendicular direction, and the urine sucking needle sucks urine under the action of the syringe pump, titrates the urine along a horizontal direction, and discharges the remaining urine into the overflow bucket. The device can ensure that the detected urine is the middle urine part of a detected person, and can wet the overflow bucket with the urine to make the urine detection result truly reflect the physical condition of the detected person and improve the reliability of the test result.

A heating type electronic film winding device, comprising a box body, a box door is arranged on the front side of the box body, a vertical plate is fixedly installed in the middle part of the top surface of the box body, a first motor is fixedly installed in the middle part of the right side of the vertical plate, and the controller The output end is respectively connected with the first motor and the input end of the first electric telescopic rod through a circuit, and the right side of the box body is provided with a discharge port, and a conveyor belt is arranged in the discharge port, and the left side of the conveyor belt is located at the bottom right of the upper rotating shaft , the bottom side of the rear side of the box is provided with a feed port. This device pushes the film reel on the right side to the right through the first electric telescopic rod, and through the through groove on the lower side of the film reel, the film reel can be shrunk toward the direction of the through groove when the film is cooling, reducing the size of the film reel. The diameter provides a buffer to avoid deformation or tearing of the film, and the device is located in the box to reduce heat loss, reduce the energy loss of the heating plate, and save energy.

The invention discloses a fan device for exhausting smoke and dust, which specifically comprises: a fan casing, the bottom of the fan casing is fixedly connected with a bracket, and one end of the inner wall of the fan casing is rotatably connected with a rotating fan; a filter net is arranged inside the fan casing at The part on one side of the rotating fan, the position of the filter screen is penetrated and rotatably connected with a rotating shaft, one end of the rotating shaft runs through the rotating fan and is fixedly connected with the drive shaft of the driving motor; the cleaning device is arranged on the rotating shaft away from One end of the driving motor, and the cleaning device is fixedly connected with the rotating shaft. The present invention relates to the technical field of fans. This smoke and dust discharge fan device can filter the large particles of impurities in the flue gas through the filter, avoiding the discharge of large particles of impurities into the air to pollute the environment, and can clean the surface of the filter to avoid the accumulation of dust on the surface of the filter and affect the ventilation. Efficiency with the ability to automatically change storage boxes.
