Description

Portable oxygen cylinder
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a portable oxygen cylinder.
Background
It is well known that oxygen is the gas on which humans rely for survival. In recent years, with the emission of automobile exhaust and industrial waste gas, the air environment is more and more severe, the haze weather is increasingly intensified, and pure oxygen breathing in nature becomes a luxury. People are easy to cause acute upper respiratory tract infection, acute tracheobronchial pneumonia, pulmonary heart disease and asthma attack in severe air environment; hypoxia aggravates blood circulation disorder, induces the attack of cardiovascular and cerebrovascular diseases such as angina pectoris, myocardial infarction, hypertension, cerebral hemorrhage, coronary heart disease and the like, and threatens life safety. Oxygen inhalation is an important rescue measure, can correct the oxygen deficiency state of the organism, is very important for relieving the oxygen deficiency symptom of the sick and wounded, and whether the sick and wounded can inhale oxygen in time in gold 1 hour or platinum ten minutes for rescue is an important factor for reducing the death rate and improving the rescue ability of the battle site, so the portable oxygen bottle becomes more important.
At present, most portable oxygen bottles on the market pressurize and fill oxygen into a gas tank, and directly inhale, insert a conduit and install a mask to inhale the oxygen by using a squeezing type valve. For example, chinese patent CN202715100U discloses a portable oxygen cylinder, which is composed of an oxygen cylinder, an oxygen therapy device and a connection therebetween; and the portable oxygen cylinder disclosed in chinese patent CN2779209Y is composed of an oxygen tank and a valve. The products have the advantages of small size, portability and capability of enabling people to use the products on plateaus and other places at any time and any place; however, the oxygen cylinder belongs to a pressure container, has certain danger when in use, and is managed by special equipment listed in China. The oxygen cylinder is generally of a cylindrical thin and high structure, the bottom surface of the oxygen cylinder is not designed into a plane structure but is designed into a slightly-outward-protruding arc-shaped plane, the stability is poor, the oxygen cylinder is vertically placed on the plane when in use, and the oxygen cylinder is extremely easy to knock down or topple over due to slight shaking due to poor stability, can roll around after toppling over, is extremely easy to collide with other objects, and has more obvious defects; in addition, when the oxygen cylinder is used in a high-temperature environment, the pressure in the oxygen cylinder with overhigh temperature is increased, and danger is easy to occur.
Disclosure of Invention
The portable oxygen cylinder aims at the problems that the portable oxygen cylinder in the prior art is poor in stability, easy to roll and easy to explode when the temperature is too high.
The invention provides a portable oxygen cylinder which comprises an oxygen cylinder, wherein the oxygen cylinder comprises a cylinder body and a cylinder top, an air outlet is formed in the cylinder top, a constant-flow valve is arranged at the upper end of the cylinder top, oxygen in the oxygen cylinder is connected with the external air outlet through the constant-flow valve, and a sealing rubber ring and a dust screen are arranged at the joint of the constant-flow valve; the oxygen tank is characterized in that a square protective shell is arranged outside the oxygen tank and made of plastic materials, the inner wall of the protective shell is tangent to the outer wall of the oxygen tank, a water injection cavity is arranged inside the protective shell, a water injection port and a water outlet are arranged on the protective shell, the water injection port is arranged at the top of the protective shell, a plug for plugging the water injection port is arranged on the water injection port, the water outlet is arranged at the bottom of the protective shell opposite to the water injection port, and a plug for plugging the water outlet is also arranged on the water outlet; the protective shell is provided with a detachable clip.
The working principle of the invention is as follows: the portable oxygen bottle comprises an oxygen tank, wherein the oxygen tank comprises a tank body and a tank top, the tank body is used for storing high-pressure oxygen, the oxygen flows out from an air outlet after being controlled by a constant-flow valve arranged on the tank top, in order to prevent dust and avoid air leakage, a sealing ring and a dust screen are arranged at the joint of the constant-flow valve, and an oxygen absorption pipeline is connected to the air outlet to absorb oxygen. The cladding of square protecting sheathing is in the outside of can body, but the bottom of tank deck and can body spills, during the use with the can body insert in protecting sheathing can, because the outer wall of can body is tangent with protecting sheathing's inner wall, in addition protecting sheathing is that plastic material makes, can ensure the laminating that can body and protecting sheathing are tight, can be crashproof again when the oxygen jar falls down on the second place, the upset of oxygen jar has still been avoided to square protecting sheathing on the third place, play a fine guard action to the oxygen jar.
In addition, because the water injection chamber is in the middle of the protecting sheathing, when ambient temperature was too high, when passing through the water filling port with microthermal liquid like water and pouring into the water injection chamber, plugged up the water filling port with the stopper, the liquid in the water injection intracavity can prevent the temperature rising of oxygen jar, and then takes place dangerously, when need not cool down, opens the stopper of water outlet department, with water put out can.
The setting of checkpost is when needs hang portable oxygen cylinder in somewhere, with the checkpost installation hang can.
The invention has the beneficial effects that: according to the portable oxygen tank, the square protective shell is arranged, so that the stability of the oxygen tank can be improved, meanwhile, the danger caused by high temperature can be avoided due to the arrangement of the water injection cavity, when the portable oxygen tank is transported and stored, the oxygen tank with the protective shell is of the square structure, when a plurality of portable oxygen tanks are put together, due to the fact that the gaps between the adjacent portable oxygen tanks are small, the large-scale shaking is avoided, and the mutual friction is reduced.
