Description

Safety lifter get down device for ambulance and ambulance with the same}

The present invention relates to a stretcher safety unloading device and an ambulance equipped with the same. More specifically, when unloading a stretcher carrying a patient, even if carelessness or mistake occurs, the stretcher randomly falls to the ground and crashes, preventing the patient from being injured. It relates to an effectively preventable stretcher safe unloading device and an ambulance equipped therewith.

An ambulance is a vehicle that quickly transports critically ill or injured patients (hereinafter referred to as patients) to a hospital. Usually, it is called ambulance as it is in English.

The ambulance is equipped with various medical equipment, tools, and supplies for quick and immediate treatment of patients. In particular, a stretcher loading bed is provided on one side of the ambulance for raising or lowering the stretcher.

For reference, a stretcher refers to a foldable mobile bed that is not only movable but also foldable. To reduce volume, the bridge portion is structured to fold or unfold. Wheels are provided at the ends of the legs. The wheels roll on the ground and also move on rails on the stretcher loading bed.

The stretcher is usually loaded, that is, fixed, on the stretcher loading bed in the ambulance with the legs folded. Then, when the ambulance arrives at the scene, the paramedics unload the stretcher from the stretcher loading bed, that is, lower it to the ground. At this time, the folded legs naturally unfold and the wheels provided at the ends of the legs touch the ground. . Accordingly, the stretcher is quickly moved to the position of the patient to load the patient, and then the stretcher carrying the patient is loaded onto the stretcher loading bed in the opposite operation as above. Meanwhile, upon arriving at the hospital, the paramedics unload the stretcher carrying the patient from the stretcher loading bed and then transfer the patient to the portable bed provided by the hospital.

However, existing ambulances are not equipped with any means to guide the unloading of the stretcher stably when unloading it from the stretcher loading bed, and the work has to be done solely based on the abilities of the paramedics, so depending on the time, that is, the patient There is a problem that can lead to a dangerous situation when unloading a loaded stretcher from the stretcher loading bed.

This will be explained in more detail. For example, assuming that a stretcher carrying a man weighing approximately 60 kg is unloaded from the stretcher loading bed of an ambulance, two paramedics will work on it. If the legs of the stretcher are not fully extended due to a mistake or due to the heavy weight, the stretcher may be unloaded from the stretcher loading bed of an ambulance. The need for safety measures arises because, if placed or missed, the stretcher may randomly fall and collide with the ground (floor), which may lead to injury to the patient.

Referring to these drawings, the present invention effectively prevents the stretcher 130 from randomly falling and colliding with the ground and injuring the patient even if carelessness or mistake occurs when disembarking the stretcher 180 carrying a patient. The scope of the present invention, which can provide these effects, can be applied to the stretcher safe unloading device 140 and the ambulance 100 equipped with it.

Looking at the ambulance 100 with reference to FIG. 1, the ambulance 100 is a car that quickly transports emergency patients or injured patients (hereinafter referred to as patients) to a hospital. This ambulance 100 includes an ambulance body 110 and wheels 121.

The ambulance body 110, which has a box structure, is equipped with various medical equipment, tools, and supplies for quick and immediate treatment of patients. In particular, a stretcher loading bed 130 is provided on one side of the ambulance main body 110.

The stretcher loading bed 130 forms a place where the stretcher 130 is loaded. This main stretcher loading bed 130 includes rails 131 and an inclined surface 132 on which the wheels 184 of the main stretcher 180 can move. The inclined surface 132 forms one front side of the main stretcher loading bed 130 and guides the wheels 184 of the main stretcher 180 so that it can be safely unloaded.

The main stretcher 180 that is loaded or unloaded on the main stretcher loading bed 130 refers to a portable cot as described above. That is, the main stretcher 180 includes a mat 181, a mat support frame 182 that supports the mat 181, a foldable leg 183 that is foldably coupled to the mat support frame 182, and a foldable leg 183. It includes a plurality of wheels 184 rotatably coupled to the ends of the legs 183. A total of four wheels 184 are provided, one pair at the front and rear of the foldable leg 183, and each pair of wheels 184 is connected by a shaft 185.

Meanwhile, as described above, assuming that the stretcher 180 carrying a man weighing approximately 60 kg is unloaded from the stretcher loading bed 130, two paramedics will work, and if the stretcher 180 carrying a man weighing approximately 60 kg is unloaded from the stretcher loading bed 130, the stretcher 180 will be unloaded by mistake or due to the high weight. If the foldable leg 183 of the 180 is not fully extended and the stretcher 180 is placed or lost, the stretcher 180 may randomly fall and collide with the ground (floor), resulting in injury to the patient.

Accordingly, in the case of this embodiment, the stretcher safe unloading device 140 is applied to solve this problem.

The main stretcher safety unloading device 140 is coupled to the main stretcher loading bed 130, and when the main stretcher 180 is unloaded from the main stretcher loading bed 130 as shown in FIGS. 4 to 6, the main stretcher 180 is It serves to prevent random fall and collision from the main stretcher loading bed 130 to the ground.

This main stretcher safety unloading device 140 may include a device coupling portion 141, a shaft locking portion 143, and a departure prevention protrusion portion 144. The main stretcher safety unloading device 140 is partially disposed only in a central portion of one side of the main stretcher loading bed 130, as shown. This may be a way to prevent interference with the wheels 184 of the stretcher 180.

The device coupling portion 141 is a portion coupled to one side of the main stretcher loading bed 130. In this embodiment, the device coupling portion 141 may be coupled to the lower portion of the inclined surface 132 on one side of the main stretcher loading bed 130 using a screw 142.

The shaft locking portion 143 is connected to the device coupling portion 141, and when the wheels 184 of the main stretcher 180 fall from the inclined surface 132 of the main stretcher loading bed 130, the main stretcher 180 This is the part that guides the shaft 185 to engage. When the wheels 184 of the main stretcher 180 fall from the inclined surface 132 of the main stretcher loading bed 130, the shaft 185 of the main stretcher 180 must be caught, so the shaft engaging portion 143 is The main stretcher loading bed 130 may have a shape that opens in the opposite direction on the inclined surface 132. Since the device coupling portion 141 is fixed, some elasticity may be formed in the shaft locking portion 143, which is plate-shaped.

The departure prevention protrusion 144 is formed to be bent from the end of the shaft locking portion 143 toward the main stretcher loading bed 130 and serves to prevent the main stretcher 180 from arbitrarily leaving the shaft 185.

In the case of the present embodiment, the device coupling portion 141, the shaft locking portion 143, and the separation blocking portion 144 forming the main stretcher safety unloading device 140 have been described separately, but they may be an integrated structure. In this case, the convenience of manufacturing or installation can be increased, and replacement is also easy.

Hereinafter, we will look at the operation of the stretcher safety unloading device 140.

When the ambulance 100 carrying the patient arrives at the hospital, the paramedics unload the stretcher 180 carrying the patient from the stretcher loading bed 130. At this time, as shown in Figures 4 to 5, the wheels of the stretcher 180 (184) is let off along the rails 131 and the inclined surface 132 of the main stretcher loading bed 130.

Meanwhile, when the wheels 184 of the main stretcher 180 are unloaded along the inclined surface 132 of the main stretcher loading bed 130, the shaft of the main stretcher safety unloading device 140 provided in the area of the inclined surface 132 is caught. Since the shaft 185 of the main stretcher 180 is caught on the part 143, the main stretcher 180 is prevented from falling arbitrarily.

In this state, that is, in a state in which the shaft 185 of the main stretcher 180 is caught on the shaft locking portion 143 of the main stretcher safety unloading device 140, the foldable leg 183 of the main stretcher 180 is fully unfolded and fixed. Afterwards, lift the main stretcher 180 slightly so that the shaft 185 of the main stretcher 180 comes out of the shaft locking portion 143. Then, the problem of accidental fall and collision of the stretcher 180 that may occur can be resolved.

According to this embodiment, which operates based on the structure described above, when dismounting the stretcher 180 carrying a patient, even if carelessness or mistake occurs, the stretcher 180 randomly falls to the ground and collides, causing the patient to be injured. You can effectively prevent injuries.

Figures 8 and 9 are partial structural operational diagrams of the main stretcher safe unloading device according to the second embodiment of the present invention.

Referring to these drawings, the main stretcher safety unloading device 240 according to this embodiment is also used by being coupled to one side of the main stretcher loading bed 230, and is attached to the main stretcher loading bed 230 with a screw 242. It may include a device coupling portion 241 coupled to one side, a shaft locking portion 243, and a departure prevention protrusion portion 244. Their structure, function, and role are the same as the above-described embodiment.

However, in the case of this embodiment, the main stretcher safety unloading device 240 is further provided with a shaft supporter 245 having a tunnel portion 245a. The shaft supporter 245 is connected on one side to the device coupling portion 241, while allowing the shaft locking portion 243 to slide. That is, the shaft locking portion 243 may be reduced in length as shown in FIG. 8 or may be extended in length as shown in FIG. 9 .

In this way, when the shaft locking portion 243 formed at the end of the breakaway protrusion 244 is capable of sliding movement based on the shaft supporter 245 rather than a fixed structure, it is appropriate depending on the type of the main stretcher 180 (see FIG. 3). It has the advantage of being able to be used with variable length.

Even if this embodiment is applied, when unloading the stretcher 180 carrying a patient, even if carelessness or mistake occurs, it is possible to effectively prevent the stretcher 180 from randomly falling and colliding with the ground and injuring the patient.

Figure 10 is a partially exploded perspective view of the main stretcher safe unloading device according to the third embodiment of the present invention, Figure 11 is an assembly diagram of Figure 10, Figure 12 is an operation diagram of Figure 11, and Figure 13 is a safe unloading of the main stretcher of Figure 10. This is a control block diagram for the device.

Referring to these drawings, the main stretcher safety unloading device 340 according to this embodiment is also used in conjunction with one side of the main stretcher loading bed 330.

The main stretcher loading bed 330 is provided with rails 331 and an inclined surface 332. A main stretcher presence sensor 395 is installed around the rail 331 to sense whether the main stretcher 180 (see FIG. 3) is loaded.

Meanwhile, the main stretcher safety unloading device 340 according to this embodiment is different from the structure described above, but is provided in an electric manner. This main stretcher safety unloading device 340 includes a bed coupling unit 350 coupled to the front wall 333 on one side of the main stretcher loading bed 330, and a safe unloading unit detachably connected to the bed coupling unit 350. It may include (360).

A dove tail groove (351) is formed in the bed coupling unit (350), and is coupled with a screw (351).

The safe unloading unit 360 is formed on the back of the unit body 361 and a unit body 361 equipped with electronic components inside, and has a dove tail in the dove tail groove 351 of the bed coupling unit 350. A dovetail protrusion 362 that engages and combines in a way, a warning lamp window 363 formed on the front of the unit body 361, and a pair of rolling elements 364 formed on both sides of the unit body 361. , It includes a telescopic electric boom 365 that is electrically coupled to the rolling elements 364 so that each can be extended or shortened in length. The telescopic electric boom 365 replaces the role of the shaft locking portion 143 of the first embodiment described above.

The warning lamp window 363 is turned on when the telescopic electric boom 365 is extended as shown in FIG. 12 and is actually used, visually indicating that the stretcher safety unloading device 340 according to this embodiment is in use. It plays an informing role.

Meanwhile, in this embodiment, a controller 380 is further provided to drive the telescopic electric boom 365, warning lamp window 363, etc.

The controller 380 automatically controls the operation of the telescopic electric boom 365 and the warning lamp window 363 based on the sensing operation of the main stretcher presence sensor 395. For example, as shown in Figure 4, when the main stretcher 180 is loaded around the rails 331 of the main stretcher loading bed 330, the main stretcher presence sensor 395 detects this and transmits a signal to the controller 380. Then, the controller 380 causes the telescopic electric boom 365 to extend upward as shown in FIG. 12 and turns on a green or red light in the warning lamp window 363 to prevent the stretcher 180 from falling arbitrarily. Don't let it happen. However, when the main stretcher 180 is not in the main stretcher loading bed 330, it is advantageous to have the telescopic electric boom 365 reduced to its original position as shown in FIG. 11 while the warning lamp window 363 is turned off. The controller 380 is responsible for this.

The controller 390 that performs this role may include a central processing unit (391, CPU), memory (392, MEMORY), and a support circuit (393, SUPPORT CIRCUIT).

In this embodiment, the central processing unit 391 is an industrially applicable device to automatically control the operation of the telescopic electric boom 365 and the warning lamp window 363 based on the sensing operation of the stretcher presence sensor 395. It can be one of a variety of computer processors.

Memory 392 (MEMORY) is connected to the central processing unit 391. Memory 392 is a computer-readable recording medium that can be installed locally or remotely, for example, in a readily available storage medium such as random access memory (RAM), ROM, floppy disk, hard disk, or any other digital storage form. It may be at least one memory.

The support circuit 393 (SUPPORT CIRCUIT) is combined with the central processing unit 391 to support typical operations of the processor. This support circuit 393 may include a cache, power supply, clock circuit, input/output circuit, subsystem, etc.

In this embodiment, the controller 390 automatically controls the operation of the telescopic electric boom 365 and the warning lamp window 363 based on the sensing operation of the main stretcher presence sensor 395. This series of control processes, etc. It may be stored in memory 392. Typically, software routines may be stored in memory 392. Software routines may also be stored or executed by other central processing units (not shown).

Although the process according to the present invention has been described as being executed by software routines, it is also possible that at least some of the processes according to the present invention are performed by hardware. As such, the processes of the present invention may be implemented as software running on a computer system, as hardware such as an integrated circuit, or as a combination of software and hardware.

Even if this embodiment is applied, when unloading the stretcher 180 carrying a patient, even if carelessness or mistake occurs, it is possible to effectively prevent the stretcher 180 from randomly falling and colliding with the ground and injuring the patient.
