DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cardiac massage device for compressing a chest wall of a patient who has undergone cardiac arrest and performing a cardiac massage, and in particular, a cardiac massage for a patient being transported from a site away from the patient. It relates to a portable heart massage device that can be continued.

2. Description of the Related Art As a conventional portable heart massage device,
There is a device using air pressure (conventional device 1). For example, as described in Japanese Utility Model Laid-Open Publication No. 60-166333, this conventional device 1 is made of a hard plate material, has a planar fastener on an upper surface, and has a chest wall front plate attached to the chest side of a patient. , Has a belt-shaped fastener at both ends, wraps around the chest wall of the patient, and tightens both ends to the chest wall front plate so as to be freely detachable and attached. , A balloon for sternal compression that expands and contracts by discharging,
Air supplying means for supplying and discharging air from a remote portion to the balloon, inserting the balloon between the chest wall front plate and the sternum, and supplying and discharging air to the balloon by the air supplying means. , So that the patient's chest is compressed by expanding and contracting the balloon.
This conventional device 1 was proposed by the present inventor, and it was thought that this would allow chest compression heart massage.

[0003] However, the balloon of the conventional device 1 has a bottom area substantially equal to the average contact area of the carpal part of the human, so that a high pressure is required and a sufficient compression effect of the sternum is required. It was difficult to get. The cause was found to be due to the compressibility of the gas involved.After that, various trial productions were repeated for many years, but as a result the intended purpose could not be achieved, did.

As another conventional portable heart massage device, there is a device utilizing water pressure (conventional device 2). The conventional device 2 employs a piston-type hydraulic cylinder in place of the pneumatic balloon of the conventional device 1. For example, as described in Japanese Utility Model Publication No. 5-19061, a piston mounted on a chest wall front plate is used. Type hydraulic cylinder, and a piston pump connected to the cylinder by a flexible tube and mounted on an operating device. The operating device pushes and pulls the piston operating rod of the pump to reciprocate the piston of the hydraulic cylinder. The sternum is moved and the sternum is compressed by a sternum compression device provided at the lower end of the piston rod of the hydraulic cylinder. The conventional device 2 was proposed by the present inventor, and as a result, a portable heart massage device capable of accurately controlling the vertical reciprocating motion of the chest compression device from a remote portion was obtained.

[0005] The conventional device 2 was applied to an actual resuscitation method and proved to be practicable. However, it has been found that the conventional device 2 has the following problems. That is, in a normal case, the heart massage is 1
The compression is repeated about 60 to 80 times per minute, and when the piston is reciprocated at such a speed, that is, at a speed of 60 times or more per minute, the inertia of the water and the fluid Due to the resistance, the operator who operates the actuator increases the labor, not only the fatigue, but also the time when a strong negative pressure occurs in the cylinder and the outside air is sucked in or the air dissolved in the water Is released to form bubbles, which causes a decrease in the efficiency of the pump, and the like, and there is a need for improvement in this respect.

As another conventional portable heart massager,
As a method of transmitting power to a chest compression device, there is a device (conventional device 3) using a wire pulling mechanism applied to a handbrake mechanism of a motorcycle or the like. In this conventional device 3, an operating rod is provided on a cylinder erected on the front wall of the chest wall so as to be movable in the vertical direction, and a sternum compression body is fixed to a lower end of the operating rod, and the other end of the wire is connected to the operating rod. At the same time, the other end of the wire is connected to the operating device, and the operating device is operated to reciprocate the operating rod (chest compression body) in the vertical direction (see Japanese Utility Model Laid-Open No. 1-68038). .

In the conventional device 3, the chest compression device reciprocated smoothly by operating the operation device.
It was found that the wire was cut in a short time, and it was difficult to put the wire into practical use.

[0008] As another portable heart massage device, an attempt has been made to develop a device that reciprocates the chest compressions with a motor. This motor system is considered to be one of the most promising cardiac resuscitators that can perform heart massage without operator fatigue, but has not been completed at this time.

[0009]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention not only reduces the effort of a surgeon performing a heart massage, but also reduces the force of chest wall compression on the floor on which the patient is lying. The purpose of the present invention is to provide a portable heart massage device capable of continuously performing an effective heart massage from a position away from the patient even during transportation or on a soft bed. is there.

[0010]

In order to achieve the above object, the present inventor has returned to the pneumatic method based on the thoracic pump theory, which is one of the heart massage mechanisms, and has been conducting tests and research for many years. As a result, the present inventors have found that desired results can be obtained by increasing the chest wall compression area of the chest compression balloon, and have completed the present invention.

That is, in the invention according to one aspect of the present invention, a backing plate made of a hard plate material having an appropriate length is interposed at the center of a belt portion having an appropriate width and length. Equipped with one fastener structure of a planar fastener on one or both sides of both ends of the belt portion, a tightening belt device to be wound around and attached to the chest wall of a patient, and a rigid flat plate having an appropriate width and length, A chest wall front plate provided with the other fastener constituting body of the planar fastener on an upper surface, and both ends of the belt portion are detachably engaged and fixed, and a chest wall fixedly provided on a lower surface of the chest wall front plate It has a compression accordion-type balloon, an air supply sieve provided by connecting the air inlet and outlet of the balloon with a flexible air supply pipe, and two operating rods. The base ends of the two rods can be freely opened and closed A bellows operation device that is provided with the bellows interposed and fixed between the two rods, and that operates to extend and contract the bellows, wherein the bottom area of the balloon is larger than the contact area of the human carpal part. It is characterized by having been done.

With the above arrangement, when the operation device is operated to compress the bellows, the air in the bellows is pressure-introduced into the balloon through the air supply pipe, so that the balloon is inflated and the patient is inflated. Squeezing the chest wall. Further, when the bellows is extended by operating the operating device, the compressed air in the balloon returns to the bellows through the air supply pipe, and the balloon contracts flat.

In the present invention, since the bottom area of the balloon, ie, the chest wall compression area, is configured to be larger than the contact area of the wrist, a sufficient compression effect can be obtained even with low-pressure air. That is, the area of the chest wall presser (the bottom area of the balloon) and the compression force are proportional to each other according to the principle of Pascal, and 1 kg of force is applied per 1 cm ² under one atmosphere. Dividing by the area gives the required balloon internal pressure. Therefore, in order to apply a force of 50 kg to the chest wall, the contact area of the carpal part is, for example, 50 cm ^2.
If 50 と 50 = 1, a pressure of 2 atm is required in addition to 1 atm and atmospheric pressure, but the compression area (bottom area) of the balloon
Is set to 200 cm ² , 1.25 atm is sufficient. In such a low pressure range, the gas compressibility according to Boyle-Charles' law also becomes small.

With this configuration, the air can be deflated in a flat shape by opening the valve and exhausting the air in the balloon and the bellows, which is convenient for storage and handling of the device. Then, before use, the bellows is extended with the valve open to draw air into the bellows, and then the valve is closed for use.

In the present invention, a stand rod having an appropriate length with one end pivotally attached to one end of the operating rod of the operating device is provided on the base end side of the operating rod. Lock means may be provided for locking the rod so that the movement in the rotation direction of the rod can be released in a posture in which the rod is opened at a predetermined angle with respect to the operating rod. With this configuration, in addition to the above-described operation, it is possible to perform a heart massage by opening the rod for a stand at a predetermined angle and using the stand as a stand to fix one operation rod, and opening and closing the other operation rod with both hands. Since it is possible, operation is further simplified and fatigue is reduced.
