The application discloses a kind of children respiratory tract secretion negative pressure cleaning equipment, comprising: cleaning device and medicament adding device.Cleaning device includes secretion suction pipe, secretion collection tank and negative pressure generator, one end of secretion suction pipe is equipped with suction head, a plurality of suction holes are opened in the lateral wall of suction head, a plurality of suction holes are spaced distribution along the circumference of suction head, the tail end of secretion suction pipe is connected with the inlet of secretion collection tank, the outlet of secretion collection tank is connected with the inlet of negative pressure generator;Medicament adding device includes medicament injection pipe and liquid storage tank, one end of medicament injection pipe is communicated with liquid storage tank.A plurality of suction holes effectively expand the coverage of single suction, significantly reduce the risk of a single suction hole being completely blocked, ensure the continuity of suction process, while avoiding potential damage to respiratory mucosa by pressure fluctuation.By the way of lubricating mucosa, diluting viscous secretion, thereby reducing suction resistance and improving the tolerance of sick children.

This utility model discloses an intelligent air mattress for turning over and preventing pressure sores in critically ill cardiovascular patients, belonging to the field of medical device technology. The utility model includes a base plate with a baffle fixedly connected to the top outer wall of the base plate. By setting up a control panel and automatic telescopic rods, the extension distance of multiple automatic telescopic rods at the bottom can be changed by operating the control panel, thereby causing the automatic telescopic rods to push one side of the air mattress upwards. The other side of the air mattress is confined to the base plate, so the movement of the automatic telescopic rods causes the air mattress to bend, with the bending part precisely near the waist. This allows the patient to adjust the shape of the bed to conform to the human body curve by controlling the control panel. The height of the automatic telescopic rods can be adjusted by the control panel, causing the telescopic rods to push one side of the air mattress upwards and bend it, preventing pressure sores. For critically ill cardiovascular patients, prolonged lying flat can easily lead to the accumulation of respiratory secretions in the lungs, making it difficult to expel and causing breathing difficulties.

This invention relates to the field of medical device technology and discloses a visual respiratory secretion negative pressure suction device, comprising: a collection bottle made of transparent material with a visible cavity, the top of which is provided with an air inlet and an air outlet for establishing a negative pressure passage and observing the secretion collection status in real time; and a switchable connector detachably connected to the air inlet, constituting an integrated dynamic tube diameter control unit, including a central seat and a rotary switching plate arranged coaxially. The central seat is provided with multiple sets of first through-holes along the axial direction, and the flow cross-section of each set of first through-holes decreases in a stepped manner. This device significantly improves the precise matching capability of secretion drainage. By using the selection of the suction tube diameter as a pre-forced step and forming a physical cascade match with the multiple sets of first through-holes in the switchable connector that decrease in a stepped manner, secretions of different viscosities can be drawn out under optimal flow resistance conditions.
