Stretcher for patient transport {Stretcher for patient transport}

The present invention relates to a stretcher for transporting a patient, and more particularly, the legs are configured to be foldable and unfoldable using cylinders, and the legs or back can be lifted or erected according to the patient's condition, and the patient can By configuring the bed member to lie down movably, it is possible to protect the musculoskeletal system disease of paramedics from the impact force applied by the impact by preventing the leg part from being folded while colliding with the ambulance, and the patient can be transported more safely and comfortably And, it is possible to move the center of gravity by moving the bed member, it relates to a stretcher for transporting the patient to allow the patient to board the ambulance easily.

In general, transporting an emergency patient who has suffered a traffic accident to a hospital is a difficult task that requires careful attention, and sometimes patients suffer greater injuries due to mistakes during transport.

Therefore, as a means of moving the patient from the location where the patient occurred to the ambulance vehicle or from the ambulance vehicle to the emergency room of the hospital, the ambulance stretcher is always seated in the ambulance vehicle and is used for the movement of the patient.

In this stretcher, a mattress is installed on the inside of a square frame-shaped main frame, and handles are installed on both sides of the main frame.

On the other hand, auxiliary wheels are installed on the front of the main frame to guide the stretcher when seated in the ambulance.

In addition, a front support bar is installed at the lower front of the main frame so as to be rotatable via a front fixing hinge, a front wheel is installed at an end of the front support bar, and a front connecting bar is installed between the front support bars.

In addition, a rear support rod is installed at the lower rear of the main frame so as to be rotatable via a rear fixing hinge, a rear wheel is installed at an end of the rear support rod, and a rear connecting rod is installed between the rear support rods.

A stopper coupled to a fixing means installed in the stretcher seating portion of the ambulance is installed at the center of the rear connecting rod to prevent the stretcher from moving in a state in which the stretcher is drawn into the stretcher seating portion of the ambulance.

A side connecting rod is installed between the front connecting rod and the rear connecting rod.

A central support rod is installed at the lower center of the bottom surface of the main frame to be rotatable via a central fixed hinge, and one end of the central extension rod is installed at an end of the central support rod via a movable hinge, and the other end of the central extension rod is a front support rod. installed at the bottom of

On the other hand, the front support bar and the rear support bar are elastically installed via an elastic member so that they can be maintained in a vertical state.

When the stretcher is withdrawn from the ambulance, the front support rod and the rear support rod are maintained in a vertical state, so that the front wheel and the rear wheel contact the ground, so that the stretcher can be easily moved.

When transferring a patient using a stretcher, the patient is laid on a mattress and pushed while holding a main frame or a handle.

And when the stretcher is seated on the ambulance, when the auxiliary wheel is brought into contact with the bottom surface of the stretcher seating portion and then the stretcher is pushed, the front support bar is in contact with the bottom surface of the stretcher seating portion and is rotated around the front fixed hinge.

When the front support rod is rotated, the central extension rod is rotated around the movable hinge, and after the central extension rod is rotated, the central support rod is rotated around the central fixed hinge.

Meanwhile, since the side connecting rods installed on the front supporting rods are moved together, the rear supporting rods installed on the side connecting rods are rotated around the rear fixed hinge.

That is, the front support bar, the central extension bar, the center support bar, and the rear support bar are folded, and when the front end of the stretcher is seated on the bottom surface of the stretcher seat, the auxiliary wheel is in contact, and when the stretcher is seated to some extent, the surface of the center extension rod The surface of the stretcher seat is contacted, and when the stretcher is fully seated, the front wheel is contacted.

As described above, when the stretcher is seated on the stretcher seat, the stopper installed on the rear connecting rod is inserted into the fixing means installed in the vehicle and fixed.

On the other hand, when the stretcher seated in the ambulance is pulled out, the fixing force of the fixing means is released and the main frame is pulled, the stopper is separated from the fixing means, and the front wheels and auxiliary wheels are rotated while being in contact with the stretcher seating part to move the stretcher. It is withdrawn, and at this time, the front support bar and the rear support bar are maintained in a vertical state by the restoring force of the elastic member.

However, when these conventional stretchers are seated on an ambulance, the central extension rod contacts the bottom surface of the stretcher seat, causing friction, and due to the friction, excessive force must be transmitted when the stretcher is seated, which increases fatigue of the transporter as well as , there was a problem that interfered with the patient's stability.

In addition, due to the friction generated on the contact surface, the contact surface (the bottom surface of the stretcher seat, and the outer surface of the central extension rod) is worn, resulting in a shortened lifespan.

On the other hand, since no means for guiding the stopper to prevent the movement of the stretcher seated in the ambulance has been devised, the vibration generated when the stretcher is seated causes the stopper to be seated in a state separated from the fixing means and the stretcher while the vehicle is driving There was a problem, such as the fluid flow and disturbing the patient's stability.

In view of this, a patient transfer stretcher for an ambulance has been proposed in Utility Model Registration Application No. 20-2009-0006206.

Looking at the conventional ambulance patient transport stretcher, a mattress is installed on the inside, handles are installed on both sides, and a main frame in the form of a square frame with auxiliary wheels installed on the front side, and a front fixed hinge on the lower front side of the main frame A front support rod installed to be rotatable, and a front wheel installed at the lower end, a rear support rod installed to be rotatable via a rear fixing hinge at the lower rear of the main frame, and rear wheels installed at the lower end, and the front support rod A front connecting rod for connecting and a rear connecting rod for connecting the rear support rod, a fixing means installed in the center of the rear connecting rod and installed in a grooved shape on a stretcher seat of an ambulance, and a stopper coupled to the fixing means, and the front For patient transfer consisting of a side connecting rod installed between the connecting rod and the rear connecting rod, and a central support rod installed rotatably through a central fixing hinge on the lower center of the bottom of the main frame and a central extension rod installed through a movable hinge at the lower end. In the stretcher, a guide wheel installed on the surface of the central extension rod to guide the stretcher in a sliding manner when the stretcher is seated on the stretcher seat of the ambulance, and a stopper on the surface of the fixing means when the stretcher is seated on the stretcher seat of the ambulance It consists of a guide wheel installed on one side of the stopper in order to guide it to be stably inserted into the fixing means along the way.

However, as described above, the conventional general ambulance patient transfer stretcher configured as described above is in contact with the stretcher seating portion when the guide wheel installed on the surface of the central extension rod is pushed into the ambulance's stretcher seating portion after loading the patient on the stretcher. Since the bottom surface of the stretcher slides smoothly without friction with the surface of the stretcher seating area and is seated, the patient is protected, and the stopper of the stretcher is easily attached to the fixing means of the stretcher seating area by the guide wheel installed on one side of the stopper. When the stretcher on which the patient is lying is drawn into the ambulance, it can be gently loaded into the ambulance without causing shock and noise to the patient. However, in order to load the stretcher into the ambulance, first, when the stretcher enters the ambulance, the auxiliary wheels are moved to the inside of the ambulance. When supported on the surface, the front support bar collides with the ambulance by pushing the stretcher while applying force to the inside of the ambulance, and as a result, the center support bar and the rear support bar are folded along with the rotation to the bottom of the main frame, and loaded into the ambulance, the front support bar When colliding with this ambulance, there is a problem in that musculoskeletal disorders are damaged due to shock applied to the arms and shoulders of paramedics.

In addition, the conventional ambulance patient transport stretcher described above is configured in a state in which the main frame with the mattress installed on the upper surface is fixed, that is, in a fixed state without moving in the front and rear directions, so that the stretcher on which the patient is lying is transported to the ambulance There is a disadvantage in that a lot of force is required because the paramedics have to push the weight of the patient on the side that is not supported by the auxiliary wheel while supporting it while loading on the support wheel.
