Therefore, the bite force of the biopsy forceps is increased, the sampling amount is greatly increased, the sampling frequency is reduced, and the application range of the biopsy forceps is expanded.

The invention belongs to the field of intelligent epidemic prevention, and relates to an active epidemic prevention device and method for intelligent recovery and detection of a mouth-nose mask. The device is combined with equipment such as a mobile phone to collect information such as a GPS of a user, the used mouth-nose mask is subjected to precise recovery management such as recovery, sealing, cross-contamination-free storage, identification, distinguishing and the like, a droplet sample on the mouth-nose mask is detected to obtain a result, information such as the GPS is combined to be fed back to a supervision department for comprehensive evaluation, and early warning and precise epidemic prevention are achieved. The device is clear in structural design, droplet samples from the upper respiratory tract, the lower respiratory tract and the digestive tract can be collected through the mouth-nose mask for detection, the efficiency is higher, a waste mouth-nose mask is reminded to be replaced and monitored, and therefore respiratory infectious diseases such as new coronavirus are found in the early stage, and positive patients arereminded to see a doctor in time; the initiative, automation and intelligence of epidemic situation monitoring are improved, the cross infection risk of medical staff and examinees is reduced, and a new direction is opened up for supervision and epidemic prevention work of respiratory infectious diseases.

The invention relates to a pulmonary ventilation function detection method and device based on a flow-volume loop graph and a medium. The detection method comprises the following steps of obtaining an electrical impedance signal of a to-be-detected object; performing amplitude solving processing on the electrical impedance signals to obtain a thoracic impedance amplitude signal sequence reflecting the ventilation conditions of the four areas; fusing the thoracic impedance amplitude signal sequences of the four areas to obtain a thoracic impedance characteristic value sequence; converting the thoracic impedance characteristic value sequence into a lung volume sequence, performing digital differential processing on the lung volume sequence to obtain a lung ventilation flow sequence, and generating a total flow-volume loop graph and a flow-volume loop graph of each area; and obtaining a total pulmonary ventilation function and a pulmonary ventilation function detection result of each region based on the flow-volume loop graph. Compared with the prior art, the method has the advantages of simple measurement process, easiness in implementation, no cross infection risk, accuracy, reliability, capability of being popularized and applied and the like.

The invention discloses a reusable breathable antibacterial electrode plate and a preparation method thereof. The reusable breathable antibacterial electrode plate comprises an electrode plate body and a conductive film, the conductive film is sequentially composed of a hydrogel layer, a silver layer and a hydrocolloid layer from bottom to top, and the electrode plate body and the hydrocolloid layer are tightly bonded, the hydrogel layer is prepared from the following raw materials: eugenol, boron trifluoride diethyl etherate, triisopropylsilane, lipidosome, multi-walled carbon nanotubes, polydiallyldimethylammonium chloride, nanocellulose, polyacrylamide, ammonium persulfate, methacrylic anhydride, polyhexamethylene guanidine hydrochloride, octylphenol polyoxyethylene ether, Tween-80, anhydrous trifluoroacetic acid or boron trifluoride. According to the electrode plate, the composite conductive hydrogel is used as a conductive film, so that the electrode plate is good in conductivityand biological safety, and still has self-adhesion, air permeability, sweat absorbability and antibacterial property under the action of sweat, slight deformation can be achieved according to human skin elasticity, and electric signal stability is not affected, and the electrode plate is convenient to remove and can be repeatedly used.

The present invention relates to a medical catheter and a medical device comprising the same, the medical catheter comprising an outer tube main body section, an outer tube curved section, and an outer tube head section, the medical catheter further comprising a support part and a passage, the support part being filled with a medium through the passage into a storage cavity, so that the support part is expanded or the medium is extracted from the storage cavity through the passage, and the supporting part is contracted. The medical device comprises the medical catheter, an inner tube and a handle, the inner tube and the handle are used in cooperation with the medical catheter, and the far end of the inner tube enters the handle from the channel of the handle, penetrates into the medical catheter and extends out of the far end of the medical catheter. The stability of the medical device is enhanced by arranging the supporting part, the storage cavity in the supporting part is filled with a medium through the passage, the supporting part is expanded and drives the whole medical catheter to move and be tightly attached to the intestinal wall, the intestinal space is expanded through the supporting part, the distance from the inner tube to the nipple is increased, and the medical device is more stable. And space and stability are provided for operation of the inner pipe.

The invention discloses a urine guide suit for the urology department. The urine guide suit comprises a main unit, a pump valve assembly which is detachably installed on the main unit, and a urine guide pipe and a urine bag which are connected with the pump valve assembly through hoses respectively. The urine guide pipe comprises a pipe body, a connecting cover connected to one end of the pipe body, a communicating cover connected to one end of the connecting cover, a bag body connected to the end, close to the connecting cover, of the pipe body, and a pipe connecting part connected to the end, away from the connecting cover, of the pipe body. A heating inner pipe a, a heating inner pipe b and a bag body liquid injecting pipe are integrally formed on the inner wall of the pipe body. A connecting plug a and a connecting plug b which are through at two ends are formed at the positions, corresponding to the heating inner pipe a and the heating inner pipe b, of one end of the connecting cover respectively.
