Description

[Detailed explanation of the invention] [Industrial application field] This invention is a device that can perform emergency safety first aid such as cardiopulmonary resuscitation and airway opening, which is used to transport emergency patients to the nearest emergency hospital by placing them in an ambulance on the way. Regarding anti-vibration stretchers.

[Prior Art] Conventionally, there are the types of stretch chairs for ambulances shown in Figs. 6 and 7, in which a bed frame mounted on a tire-equipped trolley is placed on the lower body side and upper body side when lying on their back. It is divided into sections, and a single piece of urethane mat is laid over the inside of each section, which is lattice-plated with round pipes (not shown).

[Problem that the invention aims to solve] Recently, the influence of vibrations on transporting injured and sick people has been considered a problem, and when transporting emergency patients, how to keep them more stable has become an important issue. When operating an ambulance, we pay close attention to the road surface and traffic conditions, and take the utmost care to ensure that the vehicle remains calm. It has been reported that the human body is directly transmitted to the patient and may cause pain or vomiting, especially in patients with severe illness, heart disease, or fractures, and there is a risk of worsening the symptoms.According to literature, the human body is Vibrations are attenuated at a certain frequency, but if the frequency of the applied vibration matches the natural frequency of the human body, the vibration is amplified and resonance occurs, which causes the shaking of that part to become even larger. It has been revealed that it has vibrational characteristics that have a significant psychological and physiological impact on the human body. Additionally, the Society of Emergency Medicine has published research results stating that how to reduce the effects of low frequency waves on the brains and organs of victims is an important point in preventing the severity of the injury from worsening.

The riding comfort of a stretcher for an ambulance while it is in motion is extremely uncomfortable, even for healthy people.The reason for this is that the patient is usually accommodated with the tube facing the direction of travel of the ambulance, so when the ambulance is stopped or It has also been reported that when decelerating, a person feels pressure towards the head and feels unwell.

Therefore, the vibrations that occur during transportation and the movement of the affected area during first aid treatment not only cause mental vibration and pain to emergency patients, but also affect the prognosis of patients with fractures, brain injuries, cervical spine injuries, etc. It is considered.

Therefore, looking at the above-mentioned conventional stretch tires for ambulances, all four tires are made of rubber or other plastic material, and the tire parts are either made of 100% material or have some space. Since it is made of a solid type solid type, the vibration of the tire group itself attached to the caster is almost zero.

Furthermore, since the bed surface inside the bed frame was constructed of a latticework of round pipes, it was unable to absorb vibrations at all.

In addition, cardiopulmonary resuscitation (artificial respiration, cardiac massage)
This is a critical procedure, and as shown in the Trinker Survival Curve α in Figure 8, if the timing is missed, no life-saving effect can be expected, and it is essential to improve the survival rate. However, in the case of cardiac pine surge, the upper body sinks when compressed on the urethane pine, weakening the compression effect. Although this is done as shown in Fig. 11, since the pressure is applied to the urethane mat, the compression effect is not perfect, and there is a risk that an unexpected situation may occur.

Moreover, the conventional stretcher wheels for emergency vehicles are relatively heavy, so having a back plate on hand would further increase the weight and there is no space to accommodate the cargo, so it was inevitable that the emergency vehicles, which were always on hand, would have to be taken out whenever needed. There was a risk of missing the time for first aid due to the hassle of going to the hospital. Furthermore, when securing a patient's airway, a back plate is still required, and it is a hassle to have to go to an emergency car each time.

Here, the present invention aims to provide a vibration-proof stretcher that is effective and capable of providing emergency safety first aid to solve the above-mentioned conventional problems.

[Means for Solving the Problems] The above-mentioned problems can be solved by using a vibration-proof stretcher capable of emergency safety treatment, which stretches the bed surface on the lower body side of a supine patient inside a bed frame mounted on a tire-equipped trolley. At least both sides of the bed frame are constructed with net springs that are stretched over the bed frame by a group of springs, and
The bed surface of the bed frame on the supine upper body side,
The bed frame is constructed of a back plate with a cylindrical depression part formed at a position corresponding to the head, while a mat is placed on the lower body side of the bed frame by covering the net spring, and a mat is placed on the upper body side of the bed frame by covering the back plate. This is achieved by employing the above-mentioned configuration means, in which pneumatic mats each having an air inlet and outlet are installed.

[Operation] Since the above-mentioned measures have been taken in this case, when a patient is transported supine by placing an air pillow under the cylinder on the pneumatic mat installed on the upper body side and lower body side, and on the mat, the Vibration during loading is absorbed and alleviated by the net spring tensioned by a group of springs, the pneumatic mat, and the mat, allowing the patient to rest without applying shock to the affected area.

If the patient's symptoms require cardiac surgery or airway maintenance, the air pillow is removed, the air outlet of the pneumatic mat is opened, and the air is naturally deflated for about 4 to 5 seconds depending on the weight of the upper half of the body, and the pneumatic mat is flattened. After crushing the head and sinking it into the head depression of the backboard to secure the airway, perform cardiac pine surgery on the hard backboard using the same procedure as in Figure 11.

In addition, the amount of air inflated into the pneumatic mattress should be adjusted depending on the patient's symptoms and weight differences.

[Example] An embodiment of the present invention will be described with reference to the drawings.

For a patient who requires emergency treatment for an intravenous drip, as shown in FIG. The lower end of the drip rod 18 is inserted into the tube, and a drip device (not shown) is suspended from the upper end.

[Effects of the invention] Thus, according to the present invention, it is possible to change the tires from non-puncture tires to pneumatic tires and to make the diameter of the tires a little larger, thereby alleviating the vibrations given to patients during transportation on roads with poor surfaces. I can do it. Attach a net spring to the bed surface on the lower body side inside the bed frame of the stretcher.
It can reduce the impact on the patient. A hard backboard is laid on the bed surface on the upper body side inside the bed frame of the stretcher, and a pneumatic mat is placed on top of it, and when the air is let out, it becomes possible to secure the airway and perform cardiac massage in an instant of 4 to 5 seconds.

Therefore, the use of pneumatic tires and springs is an effective structure that reduces vibration and allows the fracture patient's affected area to rest.In addition, the back plate and pneumatic mats are well-made, allowing the airway to be placed in the ideal body position. Because it is possible to secure the
For patients with cervical vertebrae injuries (however, in the case of cervical vertebrae fractures, insert a thin plate or similar under the head to prevent the head from falling), it is safe and suitable for patients with less movement of the affected area. In this position, there is no risk of stomach contents refluxing from the esophagus to the trachea, and the patient can be transported directly to the intensive care unit for treatment, which has excellent practicality and usefulness.
