Problems solved by technology

Due to its small capacity and the oxygen is stored in gaseous form, as the amount of oxygen decreases, its output pressure gradually weakens and cannot meet the demand for oxygen supply. At this time, it is necessary to manually press and apply external force to ensure normal oxygen output. The operation is troublesome and The oxygen supply effect is not good, and there is a big shortage in use

Embodiment 1

[0013] In order to overcome the defects of the existing oxygen bag that the amount of oxygen is reduced and the output pressure is gradually weakened, it is necessary to press and apply external force by manpower to ensure the normal output of oxygen. This embodiment provides a figure 1 and figure 2 Shown is a spring supply pressure medical support device.

[0014] The present invention comprises a bag body and an oxygen conduit 2. The bag body is cylindrical when it is filled with oxygen. The inner surfaces of the two bottom surfaces of the cylindrical bag body are provided with a circular hard plate 3 having the same shape as the bottom surface. A spring 1 is arranged in the bag body. The two joints of 1 are respectively arranged on the centers of two circular hard plates 3 .

[0015] Such a structure makes when the oxygen volume decreases and the output pressure weakens during the use of the oxygen bag, the spring 1 arranged inside the oxygen bag will automatically shrink...

Embodiment 2

[0017] On the basis of Example 1, the above-mentioned spring 1 is stretched when the oxygen bag is full of gas, and the oxygen conduit 2 is arranged on one of the bottom surfaces of the bag body, and passes through the bottom surface, the circular hard plate 3 and the oxygen storage in the bag body The space communicates. Along with the reduction of the oxygen in the oxygen bag, the spring 1 shrinks and compresses the oxygen supply bag gradually, until the oxygen supply is finished, the spring 1 returns to the unstretched state, and the oxygen bag is also compressed to the minimum state. When the oxygen bag is full of air, the stretched state of the spring 1 makes the tension of the spring 1 be used as the power to compress the oxygen bag. The advantage of the oxygen conduit being arranged on the bottom surface is that the oxygen conduit 2 is not easily affected when the oxygen bag is expanded or contracted, so it is not easy to be damaged after long-term use.

Abstract

The invention belongs to the technical field of medical supplies, and particularly provides a spring pressure medical oxygen supply device comprising a bag body and an oxygen tube. The bag body takes the shape of a column when being filled with oxygen, round hard plates taking the same shape as those of two bottom surfaces of the column shaped bag body are arranged on the inner surfaces of the two bottom surfaces of the column shaped bag body, a spring is arranged in the bag body, and two connectors of the spring are respectively arranged in the centers of the two round hard plates. The spring is stretched when the oxygen bag is filled with oxygen; when output pressure is reduced due to decrease of oxygen content during the use of the oxygen bag, the spring in the oxygen bag retracts automatically to gradually reduce the volume of the oxygen bag until oxygen supply pressure is output normally, so that the oxygen uptake demand of a patient is met. The spring pressure medical oxygen supply device overcomes the defect that during the using process of a conventional oxygen bag, when output pressure gradually weakens due to the reduction of oxygen content, oxygen is not output normally unless external force is applied by pressing the oxygen bag.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, in particular to a spring supply pressure medical support device. Background technique [0002] Oxygen bags are clinically commonly used oxygen containers, often used in patient transfer or first aid. Due to its small capacity and the oxygen is stored in gaseous form, as the amount of oxygen decreases, its output pressure gradually weakens and cannot meet the demand for oxygen supply. At this time, it is necessary to manually press and apply external force to ensure normal oxygen output. The operation is troublesome and The oxygen supply effect is not good, and there is a big deficiency in use. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcoming that the output pressure gradually weakens with the reduction of the amount of oxygen in the use of the oxygen bag, and the normal output of oxygen must be ensured by manpower pressing and app...
