Description

Medical oxygen cylinder carrier of static is prevented to pair

Technical Field

The invention relates to the field of carriers, in particular to a duplex anti-static medical oxygen cylinder carrier.

Background

The oxygen cylinder is a very frequently used and very important medical device in a hospital, and is mainly used for the auxiliary treatment of respiratory system diseases (such as asthma, bronchitis, pulmonary heart disease and the like) and heart and cerebrovascular system diseases (such as coronary heart disease, myocardial infarction, cerebral hemorrhage and cerebral infarction) caused by oxygen deficiency so as to relieve the oxygen deficiency symptom; can also be used for health care oxygen inhalation or rapid relief of fatigue after mental labor and physical labor; oxygen cylinder erects in the ward generally during oxygen therapy, because oxygen cylinder is thin high, stability is very poor, if touch carelessly, takes place to empty very easily, in case empty, the patient will be very dangerous, and oxygen cylinder is from great moreover, need remove after using up and change new oxygen cylinder, and the body is smooth cylinder, does not have the stress point, is difficult to the transport.

The oxygen cylinder is a high-pressure container for storing and transporting oxygen, generally, a cylindrical airtight bottle body is made of alloy structural steel through stamping and welding, the whole weight is larger after the oxygen cylinder is filled with high-pressure oxygen, and the oxygen cylinder can be lifted and moved by two workers in a close-distance moving mode, but the danger is larger, and the personal safety of peripheral personnel is also threatened greatly; the transportation of longer distance can be realized through the oxygen cylinder carrier, the oxygen cylinder carrier usually includes the automobile body of slim and long type, the automobile body lower extreme has the layer board, the lower part of automobile body is provided with the gyro wheel, when carrying the oxygen cylinder, adjust the automobile body to vertical state, a staff lifts the bottom one side of oxygen cylinder off ground earlier, another staff impels the automobile body, make the layer board stretch into between the bottom surface and the ground of oxygen cylinder, then release the oxygen cylinder, the bottom of oxygen cylinder just is located the layer board, fix the jar body on the carrier main part with the bandage, pull the upper end of automobile body backward again, make the automobile body incline backward, it shifts the oxygen cylinder to promote the automobile body at last, this kind of method needs two people to cooperate just can accomplish, and consuming time and difficultly, efficiency is lower.

The invention patent with publication number CN107600130A discloses a medical oxygen bottle carrier, in order to make a pushing plate push an oxygen bottle forward to incline, a supporting plate is required to press the ground tightly and the carrier body is pushed forward, so that the pushing plate is pushed forward by the transmission of a bevel gear transmission rod, after the pushing plate pushes the oxygen bottle forward to generate a gap with the ground, the carrier body is pushed forward to insert the supporting plate into the lower side of the oxygen bottle, and the carrier body is pushed backward, thereby completing the loading of the oxygen bottle, but the technical defects are as follows: firstly, the oxygen cylinder is a slender cylinder, when the pushing plate pushes the oxygen cylinder to incline forwards, the gravity center of the oxygen cylinder is easy to move forwards and exceeds the range of the bottom of the oxygen cylinder, so that the oxygen cylinder drives the carrier to dump forwards through the protective belt, personnel are easy to hurt, and high-pressure oxygen in the oxygen cylinder can be exploded due to large vibration, thereby causing greater safety accidents; secondly, waterproof and anti-skid coatings are generally brushed on the ground of the ward, and when the carrier body is pushed forwards, the supporting plate always presses the ground, so that the ground coating can be scratched, scraping noise can be generated, and the recovery of patients is not favorable; the structure is unreasonable, the pushing plate can be extended forwards and the oxygen cylinder can be pushed forwards by the forward tilting carrier body, and when the supporting plate is about to be inserted into the lower end of the oxygen cylinder, if the oxygen cylinder is not tilted forwards, the supporting plate cannot be inserted into the lower end of the oxygen cylinder; if the oxygen cylinder is inclined forwards, the oxygen cylinder moves forwards continuously to ensure that the oxygen cylinder inclines forwards in the process that the supporting plate is inserted into the lower end of the oxygen cylinder, so that the oxygen cylinder is toppled forwards to cause safety accidents; fourthly, the operation is very difficult, and an operator needs to control the proper forward inclination angle of the carrier body and push the carrier to move forward to insert the supporting plate into the lower end of the oxygen cylinder in the process of loading the oxygen cylinder; the carrier inclines forward the angle undersize, and the gap between oxygen cylinder and the ground is not enough inserts the layer board, and the carrier inclines forward the angle oversize, will make the oxygen cylinder empty forward again, and the operation degree of difficulty when uninstalling the oxygen cylinder is also great.
