Lung volume reduction is performed in a minimally invasive manner by isolating a lung tissue segment, optionally reducing gas flow obstructions within the segment, and aspirating the segment to cause the segment to at least partially collapse. Further optionally, external pressure may be applied on the segment to assist in complete collapse. Reduction of gas flow obstructions may be achieved in a variety of ways, including over inflation of the lung, introduction of mucolytic or dilation agents, application of vibrational energy, induction of absorption atelectasis, or the like. Optionally, diagnostic procedures on the isolated lung segment may be performed, typically using the same isolation / access catheter.

A naso / orogastric device having backflow blocking means and comprises a naso / orogastric tube sized and shaped for being disposed within the esophagus so that at least a distal end thereof being placed in the stomach lumen of a patient, at least one elastic esophageal body, positioned along the naso / orogastric tube, having a pressure dependent volume, at least one esophageal sensor that detects fluid around at least one segment of the naso / orogastric tube, and a pressure regulator that regulates a pressure within the elastic esophageal body according to the detection.

A catheter having an elongated shaft formed of a polymeric tube with at least a section having an outer coiled support member wound in a first direction and embedded in the polymeric tube, and an inner coiled support member wound in a second direction opposite to the first direction. In a presently preferred embodiment, the inner coiled support member has coils spaced closer together than coils of the outer coiled support member. In one embodiment, the inner coiled support member is partially embedded in the polymeric tube.

An air pump having an impeller with double-sided blades is mounted outside an inflatable product, and has a body and a blower. The body has a first air chamber and a second air chamber communicating with each other, a first air inlet and a second air inlet formed at two ends of the first air chamber, and multiple first supplement air inlets formed through the body to communicate with the second air chamber. The blower has a motor and an impeller. The impeller driven by the motor has multiple double-sided blades capable of efficiently inflating air from the multiple first supplement air inlets or deflating air from the first air inlet. The air pump achieves to be more efficient in inflating and deflating the inflatable product, and structurally simplified to facilitate production and assembly of the air pump and cost reduction in production and assembly.

The inflation and deployment speed of an airbag of a knee-protecting airbag device is increased to quickly deploy the airbag to a position where it can protect the knees of the occupant, thereby improving the occupant protection function. An airbag (10), from a state in which it is arranged in a flat form, is folded sequentially through a first step in which a leading end (10S) is tucked and folded into the airbag (10), a second step in which left and right ends (10M) of the airbag (10) are roll-folded toward each other toward a vehicle-body-side base fabric sheet (12) on the vehicle-body side, and a third step in which the leading end side of the airbag (10) in the deploying direction (F) is roll-folded toward the base end (10T) toward the vehicle-body-side base fabric sheet (12). The folded airbag (10) is accommodated in a case together with an inflator (2), and a base end (10T) thereof is fixed to the case. Thus, an airbag device (1) is produced and is attached to a vehicle, at a position in front of the knees of the occupant.

An inflation valve seat with adjustable flow includes two valve seats and an intercommunicating valve. Each valve seat is connected to an air pump, and includes an inflation valve assembly, a deflation valve, and an air channel in communication with the air pump, the inflation valve assembly and the deflation valve. The intercommunicating valve is connected between the two valve seats to provide a disconnected state and a communicated state between the two valve seats. When the two air channels form the disconnected state, the two valve seats have a low-flow inflating state and a low-flow deflating state. When the two air channels form the communicated state, the two valve seats have a high-flow inflating state and a high-flow deflating state.

The invention discloses a self-aerating and pressure-regulating device for a rubber tire road roller, which belongs to the field of aerating and pressure-regulating devices of rubber tire road rollers. The device comprises a front wheel assembly, a frame, a cab assembly, a power system, a back wheel assembly and an air channel system, wherein the air channel system comprises an air compressor, a pressure valve bank, an aerating valve bank, rotating valves, air tank assembly, pressure gauges, rubber tires, an electromagnetic reversing valve and a deflating valve bank; the air tank assembly is connected with one end of the pressure valve bank, one end of the aerating valve bank and one pressure gauge respectively; the other end of the pressure valve bank is connected with the air compressor; the other end of the aerating valve bank is connected with another pressure gauge, one end of each of a plurality of rotating valves and the deflating valve bank respectively; and the other end of each rotating valve is connected with the rubber tires through the electromagnetic reversing valve. The self-aerating and pressure-regulating device has the advantages that: the aerating way of the conventional rubber tire road roller is greatly improved, an automatic pressure-regulating device is arranged, the complex and dangerous situations caused by an original operation method are avoided, and the reliability and operating convenience are improved.
