The utility model provides first-aid loading equipment for multiple wounded persons, which comprises a moving mechanism, a first-aid cabin, a first-aid loading device and a second-aid loading device, the loading and unloading mechanism comprises a lifting assembly and a connection assembly, and the lifting assembly comprises a lead screw; the connection assembly comprises a supporting frame and a loading platform, the supporting frame is slidably connected to the lead screw, and the loading platform is slidably connected to the supporting frame; the stretcher supporting mechanism comprises supporting rods, and the multiple supporting rods are connected to the side wall of the first-aid cabin and arranged in the height direction of the first-aid cabin. Through the lifting assembly and the connection assembly in the loading and unloading mechanism, the problem that the moving efficiency of the wounded is affected due to the fact that a chassis of transport tools such as off-road vehicles is too high is solved. The stretcher supporting mechanism makes full use of the internal space of the first-aid cabin, and therefore multiple prone wounded persons can be transported at the same time. Compared with conventional first-aid transportation equipment at the present stage, the movable first-aid transportation equipment has the remarkable advantages of being convenient to operate, high in transfer efficiency, controllable in moving process, high in space utilization rate, capable of reducing moving pain of the wounded and the like.

The invention relates to the technical field of intelligent medical instruments and wound nursing, in particular to an integrated wound monitoring and repairing method for a fluorescent nano electroactive composite material, which comprises the following steps: synchronously acquiring dual-mode signals of a fluorescence spectrum and an electrochemical impedance spectrum at a wound by using an intelligent dressing integrated with the composite material; extracting a plurality of wound physiological parameters from the dual-mode signal in real time through a signal decoupling model, forming time sequence data, and uploading the time sequence data to a cloud end; the cloud AI model performs association analysis and trend prediction on the time series data to generate a comprehensive diagnosis report; then, the system executes a hierarchical control strategy according to the report: automatically regulating and controlling low-risk parameters, generating a control request for a high-risk condition needing to be treated, manually confirming the control request through a medical care terminal, and then triggering accurate drug release and / or electrical stimulation treatment; in the whole treatment process, manual adjustment or emergency stop is allowed through the medical care terminal. According to the invention, intelligent management from perception, analysis to safety intervention of the wound is realized.

Embodiments of apparatuses and methods for providing negative pressure wound therapy to multiple wounds are disclosed. In some embodiments, an apparatus includes a negative pressure source configured to couple via a plurality of fluid flow paths to a plurality of wound dressings. The plurality of flow paths includes a plurality of calibrated leaks. The apparatus also includes a controller configured to determine a total rate of flow in the plurality of fluid flow paths and compare the total rate of flow to a plurality of thresholds associated with the plurality of calibrated leaks to determine one or more operating conditions, such as a blockage in one or more of the plurality of flow paths. An indication of the operating condition can be provided.

The invention discloses a biological polysaccharide wound dressing with the effects of diminishing inflammation, promoting healing and reducing scars and a preparation method of the biological polysaccharide wound dressing. According to the dressing, chitosan, sodium hyaluronate and the like are used as matrixes, modified biological polysaccharide and an active compound additive are compounded, and a three-dimensional network structure is constructed through a biological cross-linking agent; the preparation process adopts an isopropanol-water mixed solvent and mild conditions such as low-temperature alkalization, and is green and environment-friendly; experiments show that the dressing can achieve synergistic effects of diminishing inflammation, promoting healing and reducing scars, is excellent in biocompatibility, stable in mechanical property and controllable in sustained release of active ingredients, can remarkably shorten the wound healing time and reduce the scar hyperplasia rate, and is suitable for repairing multiple wounds such as burns and chronic ulcers.

The utility model relates to a kind of pathogenic bacteria inoculation pricking devices, needle handle bottom end is fixedly installed with external thread bolt, external thread bolt is movably installed with replaceable needle mounting seat, the bottom of replaceable needle mounting seat is fixedly installed with several pricking needles of array structure;The top of replaceable needle mounting seat is provided with cover body buckle close to the setting of circle, cover body is movably installed on cover body buckle close to the setting of circle, cover body is cylindrical tube structure with the diameter of top being matched with the diameter of needle handle, the inner diameter of cover body is matched with the outer diameter of cover body buckle close to the setting of circle;Need multiple repeated puncture, ensure the interval of wound, especially when the surface of the host surface pricking operation is flat, not only can ensure the interval of pricking wound, but also can ensure the depth of multiple wounds is consistent, improve work and operating efficiency.

An intracavitary surgical instrument comprises an operation component and a driving component that disassembled from each other, thus making full use of multiple wounds of endoscopic surgery, so that the operation component and the rod member may be placed into the cavity from wounds at different positions, reducing the corresponding wound size of the rod member, and improving the recovery speed of patients after surgery. Besides, in the assembly process of the intracavitary surgical instrument, the traction portion may pull the operating component to move in the opposite direction with the driving component, so as to facilitate the assembly of both. Meanwhile, the traction portion may further make the first operating arm and the second operating arm close to each other through the pulling action, so as to realize the electrocoagulation of biological tissues by the first operating arm and the second operating arm, and simplify the operation action.

The utility model relates to a self-made disposable flushing and drainage device which comprises at least one three-way connector, a plurality of three-way connectors are connected in series through a connecting pipe, a sputum suction pipe is inserted into one connector of each three-way connector, a flushing pipe is arranged in each sputum suction pipe, and the front ends of the sputum suction pipes and the front ends of the flushing pipes are placed in the wound of a patient. A wound is covered and sealed by a transparent application, the rear end of the flushing pipe penetrates out of the sputum suction pipe and is connected with a flushing connector, a drainage pipe is inserted into a remaining connector in the three-way connector located at the end, the drainage pipe is connected with a drainage bottle, and the drainage bottle is connected with a negative pressure source through a pipeline. A reserved pipe is inserted into the remaining connector of the three-way connector located at the tail end, and a water stop clamp is arranged on the reserved pipe.
