An intelligentized bred locust suction trapper comprises a suction trapping mechanism, a separation box, an isolation mechanism, a collection box and a centrifugal fan communicated with the separation box. The intelligentized bred locust suction trapper is characterized in that a suction head assembly is composed of a central suction head and a plurality of side suction heads arranged in a circumferential direction; an elbow is arranged between a feeding hose and the separation box; the isolation mechanism comprises a tubular isolation box shell, an isolation box rotating shaft arranged on the axis of the tubular isolation box shell, an isolation fan connected with the rotating shaft, and blades extending in the axial direction of the tubular isolation box shell, distributed in a cross mode and fixedly arranged on the isolation box rotating shaft, and the outer edges of the blades are just in contact with the inner wall of the isolation box shell. The bottom of the collection box is provided with a screening mechanism, the screening mechanism comprises a screen with meshes smaller than the body length of locusts, a fixed rotating shaft arranged in the middle of the screen and a movable rotating shaft hinged at one end of the screen, and the movable rotating shaft is connected with an output shaft of a screening motor through a driven connecting rod and a driving connecting rod which are sequentially hinged. The intelligentized bred locust suction trapper solves the problems of low trapping efficiency and poor stability of existing locust trappers.

The invention discloses a knee joint osteotomy bone slag splash prevention device, which comprises a suction device and a support unit for supporting the suction device. The suction device includes a square baffle plate with an open lower end, an engine and an engine mounted on the moving end of the engine. For the turbine above, the front side plate of the square baffle is provided with an opening, the rear side plate of the square baffle is provided with an air exhaust port, and a filter gauze is arranged on the front side of the air exhaust port. The invention drives the turbine to cut air through the engine, which can generate a relatively large suction force and realize the suction of bone residue and blood during the osteotomy process. The combination of the square baffle and the filter gauze can effectively prevent the bone residue and blood from splashing around and splashing after inhalation, which is convenient for postoperative cleaning. On the basis of the square baffle and filter gauze, the inner baffle and bone residue collection box can be configured to collect bone residue and blood intensively. The inner baffle and filter gauze are detachable for easy cleaning.

The invention relates to the technical field of medical equipment, and provides a ventilation system for an anesthesia ventilator, which includes a flow control valve, a flow sensor, a solenoid valve and a breathing valve, and the breathing valve is provided with a driving gas outlet and an exhaust port; the flow control The inlet of the valve and the inlet of the solenoid valve are respectively connected to the air source; the outlet of the flow control valve is connected to the inlet of the flow sensor; the outlet of the flow sensor is connected to the breathing valve; the execution end of the solenoid valve is connected to the breathing valve, and the solenoid The outlet of the valve is connected with the exhaust port. The present invention also provides an anesthesia ventilator, including the ventilation system of the anesthesia ventilator mentioned above.

The invention relates to a suction chamber (5a) for a water beam (1a) for jet impacting on knitted fabric, webs or non-woven fabrics (2) composed of staple fibers, endless filaments or cellulose fibers, either composed of a plurality of layers or mixture thereof. Furthermore the invention also relates to a porous suction surfaces (3a, 3b) used for sucking jetted water (4) and disposed on a lower side (5b) of the suction chamber (5a). The invention achieves the purpose that a water jet released from the water beam is not affected by the jetted water and water fog formed by the jetting in all of the longitudinal direction and / or the latitudinal direction of the water beam in the water jet travel direction, and the conventional general production of water drop under the water beam is prevented. The purpose is realized by such that the suction surfaces (3a, 3b) are disposed in an obliquely extended form, and extended from an upper region (6b) close to the water beam (1a) and / or a liquid-dripping corner (6a) to a lower region (6c) of the suction chamber (5a).

The invention discloses a multipath simulation gas suction device which comprises a first cabin, a second cabin, a gas path module and a control structure, wherein the gas pressure in the second cabin is lower than that in the first cabin; the gas path module communicates the first cabin and the second cabin and comprises a first multi-way structure capable of implementing multi-way entrance and one-way exit of gas, a first gas outlet pipe for communicating a first gas outlet of the first multi-way structure and the second cabin, and first gas inlets which are formed on the first multi-way structure and are communicated with the second cabin; the control structure controls on-off and gas flow of the first gas inlets. In the multipath simulation gas suction device, the gas pressure difference between the first cabin and the second cabin can implement the automatic gas suction process of the device; a respiratory driving mechanism does not need to be arranged; the multipath simulation gas suction device has a simple structure and is low in production cost; meanwhile, the multipath simulation gas suction device is provided with the first multi-way structure capable of implementing multi-way entrance and one-way exit of the gas, and thus, a plurality of paths of gas suction passages are formed, a plurality of gas suction processes can be simultaneously simulated, and the multipath simulation gas suction device can meet the requirement of a large-scale oxygen system test.
