The invention relates to a method, device and medium for detecting pulmonary ventilation function based on a flow-volume loop diagram. The detection method includes the following steps: acquiring an electrical impedance signal of an object to be measured; and performing amplitude processing on the electrical impedance signal , obtain the thoracic impedance amplitude signal sequence reflecting the ventilation status of the four regions; fuse the thoracic impedance amplitude signal sequence of the four regions to obtain the thoracic impedance characteristic value sequence; transform the thoracic impedance characteristic value sequence into a lung Volume series, and perform digital differential processing on the lung volume series to obtain the lung ventilation flow series, generate the total flow-volume loop diagram and the flow-volume loop diagram of each area; obtain the total flow-volume loop diagram based on the flow-volume loop diagram Pulmonary ventilation function and test results of pulmonary ventilation function in each area. Compared with the prior art, the present invention has the advantages of simple and easy implementation of the measurement process, no risk of cross-infection, accuracy and reliability, popularization and application, and the like.

The invention discloses a disinfection-free portable ear examination endoscope. A handheld endoscope comprises an endoscope handle, an endoscope body and a disposable casing, wherein the endoscope handle and the endoscope body can be separated or combined, and the endoscope body with different view direction angles can be replaced as required; and because the casing is disposable, the endoscope does not need to be specially disinfected, the risk of cross infection does not exist, thus the endoscope can be used at any time. The disinfection-free portable ear examination endoscope solves the defects that the traditional and classic ear examination endoscope can not be used in the outpatient service condition and needs high-temperature disinfection; the disinfection-free portable ear examination endoscope can be used for the situation that otolaryngologists need to replace different view direction angles at any time in outpatient service to observe ear lesion situation, and has the advantages of low cost, clear image, light and small whole system and convenient carrying.

The invention discloses a urology catheterization set, which includes a host, a pump valve assembly detachably installed on the host, and a catheter and a urine bag respectively connected to the pump valve assembly through a flexible tube; the catheter includes a tube body , the connecting cover connected to one end of the tube body, the connecting cover connected to one end of the connecting cover, the capsule connected to the outer wall of the tube close to the end of the connecting cover, and the connecting tube connected to the end of the tube body away from the connecting cover; the inner wall of the tube is integrally formed There are a heating inner tube a, a heating inner tube b, and a capsule liquid injection tube. The positions of the connecting cover corresponding to the heating inner tube a and the heating inner tube b are respectively formed with connecting plugs a and b connected at both ends; the connecting cover and the A space connecting the connecting plug a and the connecting plug b is formed between the connecting covers; the urinary catheter cooperates with the heater, the motor, and the pump valve assembly to heat the urethra to prevent urethral edema.

The invention discloses a gas-permeable antibacterial electrode sheet and a preparation method thereof, comprising a reusable electrode sheet and a conductive film detachable from the electrode sheet. The conductive film consists of a hydrogel layer, a silver layer and a hydrocolloid layer from bottom to top Composition, the electrode sheet and the hydrocolloid layer are closely pasted; the raw materials of the hydrogel layer include: eugenol, boron trifluoride ether, triisopropylsilane, liposomes, multi-walled carbon nanotubes, polydiallyl di Methylammonium chloride, nanocellulose, polyacrylamide, ammonium persulfate, methacrylic anhydride, polyhexamethylene monoguanidine hydrochloride, octylphenol polyoxyethylene ether, Tween‑80, anhydrous tris Fluoroacetic acid or boron trifluoride. The electrode sheet uses a composite conductive hydrogel as a conductive film, which has good conductivity and good biological safety. Under the action of sweat, it still has self-adhesiveness, is breathable, sweat-absorbent, and has antibacterial properties; it can be slightly deformed according to the elasticity of human skin. , without affecting the stability of the electrical signal; the electrode sheet is easy to remove and can be reused.

The invention discloses a pump valve assembly of a urinary catheterization kit. The pump valve assembly comprises a main body part; the main body part comprises a pump shell and a valve seat which isintegrally formed at the lower end of the pump shell; an inlet joint and an outlet joint are integrally formed on the side surface of the valve seat; a cylindrical valve core made of rubber is rotatably mounted in the valve seat; a valve cover is hermetically connected to the lower end of the valve seat; the upper end of the valve cover is abutted against or close to a limiting head; a piston mounting pipe is integrally formed at the lower end of the center of the valve cover; a piston is slidably mounted in the piston mounting pipe; a cover body is fixedly connected with the lower end of thepiston mounting pipe; a spring is mounted between the piston and the cover body; a centrifugal water wheel is rotatably mounted in the pump shell; a pump cover made of aluminum alloy is hermetically connected with the upper end of the pump shell; and a liquid inlet joint and a liquid outlet joint are integrally formed on the side surface of the pump shell. The pump valve assembly has functions ofisolating urine and conducting pressure through arrangement of the piston, so that an air pressure sensor does not contact the urine in any form, and cross infection is prevented.

The invention discloses an antifogging and disinfection-free portable endoscope for examining nose and throat. The handheld endoscope comprises an endoscope handle, an adjustable endoscope body and a disposal casing; the endoscope handle can be separated or combined with the endoscope body; the endoscope body with different radial angles can be replaced at any time according to the requirement; and the casing is disposable, so that the endoscope is free from being especially disinfected without the risk of cross infection and can be used at any time. Hot air current is led to the front end ofthe casing and sprayed to the outer surface of a glass sheet, and meanwhile, the surface temperature of the endoscope body is consistent with the temperature of human body by using the heat generatedby an electrothermal film, so that the invention plays a role of eliminating a fog layer. The invention overcomes the defects that the traditional classical endoscope for nose and throat cannot be used under the condition of outpatient services, requires high-temperature disinfection and is easy to generate fog, can be used for doctors in otolaryngological departments to replace different radial angles for observing the pathological conditions of the inside of the nose and the throat part in the outpatient services at any time, and has the advantages of low cost, definite image as well as lightness, smallness and portability of the whole system.
