Abstract

The utility model relates to an intelligent external chest pressing machine which can use an alternating-current or a direct-current. A soft magnetism steel cylinder is connected with the bottom of an insulated aluminium alloy cylinder. The bottom of the steel cylinder is connected with an aluminium cylinder or a copper alloy cylinder. The inner of the steel cylinder is a cylindrical electromagnet with a hollow copper pipe core. Soft magnetism steel loops are fixed to both end of the copper pipe. An enameled wire circles the outer case of the copper pipe and is between the two soft magnetism steel loops. The inner of the copper pipe is a metal round bar. The upper part of the metal round bar forms a steel bar which is made of soft magnetism steel material. The longitudinal section is in T-shape and extends out an electromagnet. A spring which is made of soft magnetism material is provided between the T-shaped head and the electromagnet. The lower part forms a copper bar which is made of copper alloy. An electromagnet is extended out by the copper bar and connected with a press head. After the power is connected, the round bar moves upwards and downwards in the copper pipe. When the pressing reaches the maximal deepness, the lower end of the steel bar just reaches the outer edge of the lower end of the steel loop. After receiving a control console and a sensor signal, a single chip computer carries out the intelligent control to the action of the electromagnet. The intelligent external chest pressing machine has the advantage of that a strong acting force is provided between the magnetic poles of a short distance (5cm) in the closed magnetic field.

Description

A kind of intelligent external chest compression machine

Affiliated technical field

This utility model relates to a kind of first aid external chest compression machine, especially AC/DC, and is simple in structure, and the efficient height is made easily, and tool is intelligent, and reliability and safe meets the human physilogical characteristic.Be fit in the institute and ambulance first aid use.

Background technology

External chest compression is the basic fundamental of clinical emergency treatment, but is all finished by manpower for a long time, has wasted a large amount of muscle power, and the medical worker presses for the external chest compression machine of the safe and effective work of a kind of energy.

At present, the external chest compression machine commodity that are commercially available almost are oxygen cylinder internal pressure, piston actuated mode, must rely on high pressure oxygen to be used as power but have, and are prone to the oxygen blast, and pressure is subjected to oxygen cylinder to influence big shortcoming.All the other patents are not outer following several: pure mechanical motor drives; Pure mechanical manpower drives; Piston of electromagnetic valve drives, above patent is difficult to become commodity, first and second kind complex structure, poor reliability, the third complex structure, inefficiency, and three kinds all have the pressure degree of depth to be difficult for dynamically control, easily to cause complication such as rib fracture, and heaviness is arranged, and be difficult to meet inherent defect such as human physilogical characteristic, it is imperative therefore to develop a kind of novel safely and effectively external chest compression machine.

Summary of the invention

In order to overcome the deficiency of existing external chest compression machine, make it satisfy safe, practical requirement, this utility model provides a kind of external chest compression machine, but this machine AC/DC, simple in structure, the efficient height, in light weight, portable band can link to each other with any respirator, and be controlled by microcomputer-based intelligent.

The technical scheme that its technical problem that solves this utility model adopts is: connect a soft magnetism steel cylinder below the insulation aluminum alloy drum, the steel cylinder below connects aluminum or copper alloy cylinder (vertical section is V-shaped), steel cylinder inside is cylindrical electric magnet, its core is a hollow copper pipe, the soft magnetism steel loop is fixed in the copper pipe two ends, enamel-covered wire is around on the copper pipe shell, between two steel loops; In the copper pipe is metal round rod, the metal round rod first half constitutes rod iron by the soft magnetic material material, the vertical section is T-shaped, and stretch out electric magnet, the spring that constitutes for the soft magnetic materials that just round bar can have been upspring between T shape head and electric magnet, Lower Half constitutes copper rod by copper alloy, and copper rod stretches out electric magnet and is connected on the press head.After the energising, round bar can be in copper pipe up and down about 5cm, the magnetically soft steel material act as the gathering magnetic field energy, as the media of electromagnetic force and mechanical force conversion, the effect of copper aluminum is to reduce magnetic field to leak.Electromagnet power supply is according to pressing depth measured by the pick off that is attached on the barrel by providing through monolithic processor controlled power source special, and controls by the single-chip microcomputer feedback.

Operation principle: after powering up, microcomputer circuit work, in control station, set compression frequency, the degree of depth, press start key, microcomputer output enabling signal, power work, the continuous adjustable voltage of output duty cycle, electromagnet current increases to maximum rapidly and since only in the metallic rod Lower Half for being difficult for the magnetic conduction district, satisfy the huge magnetic force of generation between iron staff and bottom magnetic pole, iron staff moves down, and active force also increases gradually, and this mode meets human body thorax tension force and the physiological property that according to pressing depth is directly proportional again within the specific limits, can prevent that the unexpected application of force and pressure from crossing ambassador's fracture of rib.When pushing when reaching depth capacity, rod iron reaches lower end steel loop outer rim bottom just.After voltage stopped, electric magnet magnetic field reduced to minima very soon, and thrust also reduces to minima very soon, borrowed multiple tension force of thorax and spring tension, and press head resets; One-period finishes, as does not reach assigned position, and the next cycle microcomputer will make the power supply output duty cycle raise automatically, till amplitude being increased to meet the demands; Vice versa.As linking to each other with respirator, as long as the breather and the respirator outlet tube that have baroceptor are joined, like this, when aspiratory action took place, external chest compression stopped.

Of the present utility model successfully is between magnetic pole in magnetic confining field short-distance and medium-distance (5cm) powerful active force to be arranged, and realizes that thus rectilinear motion, beneficial effect are, simply mode realizes the efficient, safe, light and intelligent of external chest compression.
