The invention relates to a device for synchronously recording the metabolism and swimming motion of fish, comprising a sealed water groove, which is connected with a water inlet tube and a water outlet tube, and a flux adjuster mounted on the water inlet tube. The water groove has annular water channel, and a water-flow generating adjusting device for controlling the water flow to flow along the annular water channel in one direction. The sealed water groove is made from transparent material. The camera device is mounted above / beside the sealed breath room. The invention can measure the basic or general metabolism, at different strengths, and record the swimming motion.

The invention discloses a soil respiration chamber. The soil respiration chamber comprises a bottom case, supporting plates, supporting legs, a sealed box, a circuit board, a control case, a long shaft, a driven shaft, a travel switch and a blade chamber cavity. When the soil respiration chamber is in use, the bottom case is adjusted to be at an appropriate height relative to the ground, a motor is controlled to rotate so as to make the blade chamber cavity cover a through hole in a right bottom plate, the blade chamber cavity and the soil surface form an airtight space through a soil ring, one end of the soil ring is buried in earth by 2-5 cm, and the other end of the soil ring is closely combined with a U-shaped sealing ring. When gas released by soil is collected, the respiration chamber is closed, a control system with a pump extracts the gas into the control system from one end of a gas inlet of the respiration chamber, then the gas is delivered into a gas analyzer from the control system, the gas analyzer analyzes the gas and then delivers the gas back into a control box, and the gas is delivered back into the respiration chamber through the control box, so that a complete closed cycle of gas extraction, collection and analysis is formed. When the respiration chamber is not use, the motor is controlled to rotate backwards so as to separate the blade chamber cavity from the right bottom plate.

A face mask apparatus is formed with a breathing chamber that provides adjustable warm and humidified air for inhalation. The breathing chamber heats cold air that is breathed in through the face mask during normal breathing, which is worn over the nose and mouth of a person. A temperature gauge monitors temperature for future adjustment of the amount of heat generating current. The air in the chamber is heated for inhalation by a resistive carbon fiber tape. The temperature of the resistive material (and by extension the warm air generated), is regulated / adjusted by increasing or decreasing the current output settings on the power source. Warm and humidified air is produced. The face mask may be part of a balaclava hood or a hat, or to other head gear, or as a stand-alone with straps around the head, optionally with an adjustable solar powered battery.

A patient interface for sealed delivery of a flow of air to ameliorate sleep disordered breathing may include: a seal-forming structure to form a pneumatic seal with the entrance to the patient's airways; a positioning and stabilising structure to maintain the seal-forming structure in sealing contact with an area surrounding the entrance to the patient's airways; a plenum chamber pressurised at a pressure above ambient pressure in use; a connection port for the delivery of the flow of breathable gas into the patient interface; and a device positioned within a breathing chamber defined, at least in part, by the seal-forming structure and the plenum chamber, wherein the device divides the breathing chamber into a posterior chamber and an anterior chamber, and wherein the device comprises a plurality of apertures such that turbulence of the air in the posterior chamber is less than turbulence in the air in the anterior chamber.

Disclosed is a battery ventilation device (10) and, more particularly, a multifunctional breathing and ventilation device applied to a casing of one of a battery sub-module, a battery module, or a battery system, and the ventilation device (10) comprises: a housing (20) attached to a vent opening of a battery casing in a sealing manner and including at least one sidewall (21); an air-permeable filter (30) for separating the interior (91) of the battery casing from a breathing chamber (22) inside the housing (20); a ventilation membrane (40) for separating the breathing chamber (22) from an external environment (92) in an airtight manner; and a breathing part (50) fluidly connecting the breathing chamber (22) to the external environment (92) and bypassing the ventilation membrane (40). Furthermore, disclosed is a battery comprising the ventilation device attached to the battery casing. The ventilation device and the battery comprising the same, according to embodiments of the present disclosure, can be applied to electric vehicles and energy storage system (ESS) battery packs.

The invention provides an oxygen consumption rate and choke point measuring device of fishes, and relates to a device for measuring oxygen consumption rate and choke point of the fishes. The invention aims to solve the problems that a special device for measuring the choke point of the fishes is lacked, and the existing oxygen consumption rate and choke point of the fishes cannot be measured in the same device by an iodometry method. A respiratory chamber of the device is of a cylinder structure; a cover plate is arranged at an opening end of the respiratory chamber; a water outlet pipe is arranged on the cover plate; a water outlet valve is formed on the water outlet pipe; an axis, vertical to the cylinder, of a pushing plate is arranged in the respiratory chamber; screw threads are formed at the external surface of a water inlet pipe; one end of the water inlet pipe is fixedly connected with the pushing plate, and the other end of the water inlet pipe is in threaded connection with a nut after penetrating through a closed end of the respiratory chamber; the nuts are in embedded connection with the external wall of the respiratory chamber; a water inlet communicated with the water inlet pipe is formed in the pushing plate; a water inlet valve is formed on the water inlet pipe; one end of a round bar is fixedly connected with the pushing plate, and the other end of the round bar penetrates through the closed end of the respiratory chamber. The device is used for measuring the oxygen consumption rate and choke point of the fishes.
