The utility model discloses a respiratory muscle training vest which comprises a vest body, an air inflation piece and four air bag pieces, the four air bag pieces are arranged on the front side of the vest body in a matrix mode and are all connected and communicated with the air inflation piece through pipelines, the two air bag pieces located on the upper portion correspond to the positions of chest cavities on the two sides respectively, and the air bag pieces are arranged on the lower portion of the vest body. The two air bag pieces located on the lower portion correspond to the positions of the abdominal cavities on the two sides respectively, the inflation pieces are used for inflating the air bag pieces, and the four air bag pieces apply compression force to the chest cavity and the abdominal cavities respectively, so that after the vest body is worn, the four air bag pieces can be inflated synchronously through the inflation pieces, and the chest cavity and the abdominal cavities can be inflated synchronously. At the moment, the air bag piece expands to apply pressure to the chest and the abdominal cavity, so that the breathing difficulty of the wearer is improved, and respiratory muscles are exercised.

The invention relates to the technical field of emergency lighting, in particular to a fire emergency lighting device which comprises a mounting shell and two lighting lamps mounted on the mounting shell. The device further comprises a box body. The lower part of the mounting shell is slidably connected with a box body in a damping manner; the upper surface of the box body is fixedly connected with two ropes fixedly connected with the mounting shell; a winding frame is connected in the box body; and a filter cotton roll is wound on a rotating shaft of the winding frame. An escape person grabs a drooping rope to move downwards, a sawtooth part of a rotating plate is forced to puncture a water bag, a filter cotton roll is soaked by water in the water bag, dust attached to the illuminating lamp is cleaned through fluff on an elastic rope, and the situation that the illuminating brightness of the illuminating lamp is affected by accumulated dust is prevented; and then the box body is separated from the mounting shell, continuously falls down, is hung in the air and is at a height which is convenient for the escape personnel to contact, so that the subsequent escape personnel can conveniently pull apart the filter cotton roll to cover the mouth and the nose, and the phenomenon that the human body cannot breathe smoothly or death due to suffocation when absorbing smoke dust is prevented.

A method operates a hearing aid, which has a sensor, a microphone, and a receiver. Breathing difficulties of a wearer are inferred on the basis of measurement data created by the sensor and a measure for a risk is determined based thereon. An activity helping the wearer is carried out depending on the measure. Furthermore, the hearing aid is configured for carrying out the method.

To solve the problem of conventional masks which are divided into an expensive and high performance NPR mask which uses a material with extremely poor breathability on a surface, and a disposable nonwoven mask for general use with a non-breathable material on a surface, and the former is highly efficient but expensive, makes breathing difficult and is specialized for medical use while the latter is inexpensive and is easy to use but has slightly inferior performance.SOLUTION: The present invention achieves high performance of a mask cover and inexpensiveness of a mask frame by cooperation of the mask cover in which a non-breathable material is used for a front face and material portions with extremely poor breathability are set on side faces using the non-breathable material, and the mask frame which supports the mask cover and displays a function of smooth breathing and comprehensive virus protection. Patent No. 7364150, which has a similar concept to the present invention, lacks a concept of cooperation between the mask cover and the mask frame, and has a weak point in which a function of virus intrusion prevention from the side faces is left to a conventional gauze mask.SELECTED DRAWING: Figure 1

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.

A headrest for preventing occipital pressure injury comprises four air bags, a control console and an air source, and the four air bags are sequentially connected end to end to form a ring; a controller is arranged in the console, and an instruction input device is connected to the input end of the controller; any air bag is communicated with the air source through an air inflation pipeline, any air inflation pipeline is provided with a ventilation electromagnetic valve, and the control end of any ventilation electromagnetic valve is in communication connection with the output end of the controller; any air bag is further connected with an exhaust device. Compared with the prior art, the head rotating device has the advantages that the head of a patient can rotate within a controllable range, and pressure injury or unsmooth breathing of the head due to the fact that the patient keeps lying on the back for a long time is prevented.

A chick basket, comprising a basket body and a plurality of partition structures arranged in the basket body, the partition structures separate the basket body into a plurality of separate cavities, the inner side walls of the four perimeters of the basket body are respectively provided with vertical support bars protruding from the basket body, the top opening area of the basket body is larger than the bottom area of the basket body, and the top height of the vertical support bars is lower than the top opening height of the basket body, so that the bottom edge of the upper basket body is just supported on the upper end of the vertical support bar of the top opening of the lower basket body. The utility model can effectively separate the chicks, prevent a large number of chicks from being too concentrated to cause problems such as trampling and breathing difficulties, facilitate the stacking of a plurality of the utility model together for use, and make the stacking more firm; not only is a plurality of air vents arranged to form a breathable gap, but air can also enter from the top gap, effectively improving the ventilation effect, preventing the up-down stacking of the basket from affecting air circulation, and ensuring smooth breathing of the chicks inside.

This invention relates to the field of respiratory mask technology, and in particular to a respiratory mask with an electrically powered air delivery mechanism. The mask includes a mask body and an external connecting cover installed at the air inlet at the front end of the mask body. An external connecting cover for connecting an external oxygen tank is snapped onto the outer opening of the external connecting cover. This respiratory mask with an electrically powered air delivery mechanism, through a lateral pressure-boosting cover with an integrated structure on one side of the external connecting cover, not only increases the delivery pressure of the oxygen tank but also reduces oxygen tank consumption. When worn alone, an electrically controlled booster fan inside the lateral pressure-boosting cover pressurizes and guides external air into the external connecting cover, greatly reducing the wearer's breathing difficulty and fatigue. A detachable external filter cover is threaded onto the outer opening of the lateral pressure-boosting cover, allowing for increased filtration through layering, making it adaptable to various working environments.
