Description

  The present invention is capable of changing the shape of the stretcher according to the passage conditions even in a narrow corridor or narrowly bent passage, and not only the burden on the patient but also the burden on the carrier is light and prompt The present invention relates to a foldable stretcher that can carry in a stretcher and rescue and transport a patient.

In recent years, with the increase in the number of emergency dispatches due to the aging of the population and the like, the labor of emergency personnel in emergency activities has increased.
The ratio of housing is very high in the place where emergency transport personnel are generated in emergency dispatch. In recent housing conditions, although barrier-free has become widespread, most emergency activities such as the vicinity of toilets and dressing rooms are common. Such narrow corridors and bent passages are used.
In order to move the patient in this narrow passage or the like, a cloth stretcher or a blanket is used, and the patient is moved using the main stretcher loaded to a position where the patient can be loaded.
If a cloth stretcher or blanket is used, the ambulance crew must continue to lift the patient with an unstable posture, and the patient will also be in an unstable posture and the burden will increase considerably.
As a result, there is a concern that this unstable posture may lead to worsening of the medical condition in patients who have life effects such as brain diseases and heart diseases.
In particular, there is a problem that cardiopulmonary resuscitation must be interrupted in patients with cardiopulmonary arrest.
Currently, there are main stretchers, folding stretchers, flat stretchers, scoop stretchers, backboards, and cloth stretchers for transport and fixing as the transport equipment loaded on high-standard ambulances. A cloth stretcher can be used with
The main stretcher is used at most emergency sites, but it is long and heavy, making it difficult to carry it into narrow streets.
A chair-like folding stretcher is used on a staircase or the like and moves with an inclination, but it is still difficult to use in a bent passage.
Although the flat stretcher is lightweight, it requires 2 to 4 people to move the patient, and the patient must move while continuing to lift the patient. Absent.
Scoop stretchers and backboards are used to fix a patient's whole body, are lightweight but long and still unsuitable for use in flexure paths.
Although the fabric stretcher is lightweight and can be used in narrow passages, the patient is moved in an unstable state, and further, the ambulance crew needs to continue to be lifted, which is a heavy burden.
Accordingly, since the main stretcher or the like cannot be carried in the patient movement in the narrow passage in the current housing situation, the movement is performed manually or by a cloth stretcher.
In manual movement, three people lift the patient and continue to lift, but the balance is unstable and the influence on the patient is great, and further movement takes time.
And even on the cloth stretcher, three people hold up the patient and continue to lift, but the balance is unstable, the load on the ambulance crew varies greatly at the lifting position, and the burden on the patient is large and it takes time to move End up.
In this way, movement on a manual or cloth stretcher places a heavy burden on emergency personnel and patients, and it takes time to move.
From the above situation, in an emergency operation using a narrow bent passage, it is possible to move the patient alone in the situation, but there is no need to continue lifting, and stable movement There is a demand for a stretcher that can be performed and that does not affect the patient and does not require time for movement.
Japanese Laid-Open Patent Publication No. 2002-345894 discloses a foldable stretcher structure. The foldable structure is obtained by using an air suction type foldable mattress, but the foldable structure has a compact shape. It is intended to improve portability and does not support transport in narrowly bent paths.
Japanese Laid-Open Patent Publication No. 2000-24037 also discloses a foldable stretcher structure, but the foldable structure is a structure that is folded in two via a connecting member provided between the support frames. This is different from the gist of the present invention because it is stored in a simple shape and is not intended to be conveyed in a folded state.

JP 2002-345894 A JP 2000-24037 A

  In view of the above technical problem, the present invention can transport a patient with a small number of transporters with a light and stable posture even in a narrow bent path, and can easily and stably stabilize the posture of the patient. The purpose of the present invention is to provide a foldable stretcher that can be conveyed quickly.

  The technical gist of the present invention is that a through hole for inserting a connector into a plurality of mounting panel members is communicated with each mounting panel member, and this connector is slidably mounted, and the connector is rigid. A plurality of core rod portions and a connecting portion that connects the core rod portions so as to be bendable. When the connecting portions are slid between the mounting panel members, the mounting panel member can be folded. And when the said connection part is slid and arrange | positioned inside each mounting panel member, it is a point by which at least 2 or more of each mounting panel member is regulated by the same surface.

If a caster is attached to the back surface of the mounting panel, the caster can be easily transported without lifting the stretcher with a patient or the like on it.
As a result, in the arrangement in which the mounting panel member and the mounting panel member are inserted and connected by the core rod portion, the mounting panel members on both sides of the core rod portion are restrained linearly by the core rod portion. When the mounting panel members are brought into contact with each other, the mounting panel members on both sides form a flush state.
On the other hand, in the arrangement in which a space is provided between the mounting panel member and the mounting panel member, and the connecting portion is positioned in the interval portion, the mounting panel members on both sides of the connecting portion can be bent via the connecting portion. It becomes.
When the length of the connecting portion is matched to the folded thickness of the mounting panel member, a compact state in which the two mounting panel members are folded and combined can be formed.

In the folding stretcher according to the present invention, it is possible to carry it in a path that is extremely narrow and bent by forming a compact shape by folding, and since the casters are provided, the burden on the emergency personnel is small, and the burden on the patient And a stable conveyance state can be obtained.
In addition, since the shape of the stretcher is changed to correspond to a narrowly bent path and transport is performed using a caster, the patient can be transported even with a small number of personnel.
Since the stretcher is compact even in a narrowly bent path, it is effective for patient movement, and by changing the stretcher shape, an appropriate stretcher shape that stabilizes the patient's posture can be selected and used. Helps prevent condition deterioration.
Moreover, since not only can it fold up compactly but the connection shape of a mounting panel member can be changed, it can be used for many uses.
For example, it can be used not only for transporting people but also equipment and the like.

FIG. 1 (a) shows a side view of a folding stretcher according to the present invention, and FIG. 1 (b) shows a top view.
The mounting panel members 20a, 20b, and 20c are arranged with the mounting surface 21 on which the transported person is placed facing upward, and the side surface 23 is connected by a connector 40 built in the mounting panel member. 10a is formed.
A cushioning material is attached to the mounting surface 21 as necessary.
Casters 22a are attached to the back surfaces 22 of the mounting panel members 20a, 20b, and 20c.
As for the caster, only the caster at one end of the stretcher is fixed to turn, and the other is set to be turnable so that the transporter can easily determine the transport direction.
Each loading panel member is provided with a hand 25 for carrying that the carrier lifts the folding stretcher.

The structure of the connector shown in FIG. 1 will be described with reference to FIG. 2 (a) showing a state where the cover 21a of the mounting panel member is removed and FIG. 2 (b) showing a state where only the connector is taken out.
The connection tool 40 includes an inner connection tool 40a and an outer connection tool 40b, and ends of the inner connection tools are connected to each other via operation portions 51a and 51b.
The coupling tool connects the core rod portion 42 with a coupling portion 43 so that the core rod portions 42 can be bent.
The connection tool 40 is composed of inner connection tool operation parts 51a and 51b provided in the operation part inner connection tool 40a and outer connection tool operation parts 52a and 52b provided in the outer connection tool 40b. It is inserted through a plurality of insertion holes 24 penetrating from the placement portion side surface 23 to the side surface 23 on both sides in the longitudinal direction.
The outer peripheral shape of the core rod portion 42 of the connector 40 corresponds to the cross-sectional shape of the insertion hole 24 as shown in FIG. The outer shape of the cross section is smaller than that of the hole 24, and the connector 40 can slide within the insertion hole 24.
In the state where the operation parts 51b and 52b are pulled out from the mounting panel member 20c, the connecting part 40 is connected to the interval 30a between the mounting panel members 20a and 20b and the interval 30b between the mounting panel members 20b and 20c. The core rod part 42 and the connecting part 43 are arranged so that 43 is located respectively.
Therefore, the placement panel members 20 a, 20 b, and 20 c can be bent at the connecting portion 43.

The core bar part 42 is a lightweight rigid body such as a pipe, and the core bar part 42 and the connecting part 43 are rotatably connected.
Specifically, for example, as shown in FIG. 1 (a), a pin 44 is disposed at the end of the core bar portion 42, and a pin hole is formed in the connecting portion 43 to be connected.
The connection between the core rod portions may be a connection using a cross shaft or the like, a connection structure using a bending member such as a rope or rubber, or a structure using the connection member itself as a bending member such as a rope or rubber.
When a predetermined play is provided between the pin diameter and the pin hole diameter, the pin connecting portion of the connecting portion 43 and the core rod portion 42 can be bent to some extent in the stretcher width direction as shown in FIG.

As shown in FIG. 4, when the placement panel member 20 a is pressed with one hand and the operation portions 51 a and 52 a are pulled with the other hand, the connector slides to the left.
Further, FIG. 5 (a) shows an appearance in a state where a cover is attached.
Then, the straight portion of the core bar portion 42 is positioned between the mounting panel members 20a, 20b, and 20c, and the mounting panel members 20a, 20b, and 20c are constrained to be flush with each other. .

As shown in FIG. 2, the operation portions 51a and 51b and the gripping portion side arms 51c and 52c are connected to each other so that the core rod side arms 51d and 52d can be bent by bending portions 53a and 53b formed by ring connection or pin connection, respectively. .
Here, by setting the lengths of the gripping part side arms 51c and 52c and the core bar side arms 51d and 52d to the total length of the distance 30a and the distance 30b, the arms are placed as shown in FIG. When the panel member side surfaces 23 are brought into contact with each other, the connector 40 corresponding to the length contracted between the placement panel member side surfaces 23 is pushed out from the placement panel member 20a. By making the length approximately equal to the length of 52c, the positions of the bent portions 53a and 53b of the grip portion side arms 51c and 52c and the core rod side arms 51d and 52d correspond to the placement portion side surface 23a.
Thus, by setting the positions of the bent portions 53a and 53b of the operation portions 51a and 52a to the positions corresponding to the placement portion side surface 23a on the operation portion side, the operation portions 51a and 52a are mounted on the bent portions 53a and 53b. It can be accommodated by being bent on the side of the mounting portion side surface 23a, and provided with a recess in the vicinity of the side surface of the mounting panel member or on the back surface of the mounting panel member.
Further, it can be used as a puller at the time of conveyance.
On the other hand, when the operation parts 51b and 52b are pushed in and the operation parts 51a and 52a are further pulled out, as shown in FIGS. 4 and 5A, the lengths of the gripper side arms 51c and 52c of the operation parts 51b and 52b and the core bar part Since the lengths of the side arms 51d and 52d are substantially equal, the bent portions 53a and 53b between the core rod portion side arms 51d and 52d and the core rod portion 42 are positioned corresponding to the placement portion side surface 23a.
Even in this state, the operation portion 51a can be bent upward by the bending portion 53a, and can be used as a puller that is easy to pull long when the stretcher is pulled.
When the operation portion 51a is not used, it can be locked and fixed to the placement panel member side.
In FIG. 5A, the operation portion 52a is folded and stored toward the side surface 23a.
It can also be locked and fixed to the mounting panel member side.
The operation unit can abut and fix the mounting panel members by engaging with the mounting panel member.

As shown in FIG. 4, the connecting tool 40 is provided with a plurality of insertion holes 24 in the mounting panel members 20a, 20b, and 20c so that the connecting tool 40 in the mounting panel members 20a, 20b, and 20c is used as a shaft. Rotation is restricted.
In this case, since the four insertion holes 24 are provided in the mounting panel member, even if the outer peripheral shape of the cross section of the connecting portion is circular, this rotation is restricted.
If the core bar portion 42 is, for example, a flat plate shape and has a non-circular cross section having rigidity in the torsional direction, the insertion hole of the mounting panel member may be one having the same cross section.

FIG. 6 shows a state where the respective mounting panel members are bent from the state shown in FIG.
A placement surface 21 for one placement panel member is formed in the upper part and can be moved by a caster 22a.
An example of the transport state in this state is shown in FIG.
Even in a path that is extremely narrow and bent, the patient 2 can sit on the placement surface 21 and the transporter 3 can quickly transport the patient 2 by supporting the body of the patient 2 by moving the caster.
Thereby, compared with the case where a patient is picked up and conveyed, the patient's posture is stabilized, and the burden on the carrier is lighter as well as the burden on the patient.
Conveyance can also be performed quickly by moving the casters.

FIG. 8 shows an example of a transport state using the stretcher in the state shown in FIG.
As a small stretcher with casters, a patient can be transported even in a narrowly bent path.
The patient 2 is stable by riding on the stretcher 10a with casters.
The burden on the patient is small, and the patient is in a stable posture with measures to prevent the deterioration of the condition.
Since the carrier 3 does not need to lift the patient or lift the stretcher, the load is light.
The folding stretcher is transported to the place where the stretcher is transported, and the patient is transferred to the stretcher by holding the handle 25 of the folding stretcher 10a, and the patient 2 is transferred to the stretcher together with the folding stretcher. The transfer in a stable state of the patient can be performed.
When the carrying handle 25 is not used, for example, the stretcher can be folded back to the back surface of the mounting panel member to make the stretcher more compact.
Moreover, the structure of the handle 25 may form a recessed part directly in a panel, and various structures are applied.

FIG. 9 shows a state in which one of the mounting panel members is inclined and fixed with a wire, and a slope is formed on the stretcher.
By pulling and extending the tilt fixing member 28a such as a wire or metal fitting from the back surface 22 of the mounting panel member 20c and attaching one end to the fastener 28b of another mounting panel member 20b, the mounting panel member 20c is tilted. The slope 21c is formed on the stretcher by being fixed.
This makes it possible to handle conveyance through stairs or slopes that are easy to convey when there is a backrest.
In the example shown in FIG. 9, the tilt angle is small, but it can be used in several stages, such as making it almost perpendicular by changing the hook position.
Further, the strength of the wire may be increased by using a metal fitting having a hook portion.

An example of another deformation state of the folding stretcher is shown in FIG.
FIG. 10A shows a case where the folding stretcher is bent, and FIG. 10B shows a case where the folding stretcher has an S shape.
The connection between the connecting portion 43 and the core rod portion 42 is bent because, for example, in the case of pin connection, a play is provided between the pin and the pin hole, so that it can be bent in the width direction of the stretcher 10a. It is easy to transport in the passage.

FIG. 11 shows an embodiment of a stretcher using five mounting panel members.
Five plate-like mounting panel members 20d, 20e, 20f, 20g, and 20h are arranged, and their side surfaces are connected by a connecting tool 40 to form a folding stretcher 10b.

FIG. 12 shows a state where the connecting tool of the stretcher is slid relative to the mounting panel member.
FIG. 12 (a) shows a state where the cover of the placement panel member is removed, and FIG. 12 (b) shows a state where the cover is attached.
In the arrangement in which the mounting panel member and the mounting panel member are connected by the core rod portion 42, the mounting panel members on both sides of the core rod portion are linearly constrained by the core rod portion 42, and are thus mounted. By placing the panel members in contact with each other, the mounting surface 21 is formed to be constrained to be flush with each other.
The operation portion 50 a protrudes from one end of the placement surface 21, but the placement surface 21 is provided with a notch portion 21 b to expose the bent portion 53 c formed of the connecting portion 43.
As a result, the operation portion can be bent upward at the bending portion 53c, and the operation portion 50a can be used as a pulling hand when the foldable stretcher is moved on a caster.

Another deformation shape when five mounting panel members are used will be described.
FIG. 13 shows a case where the mounting surface 21 for one mounting panel member 20d is formed on the upper part, with five mounting panel members 20d, 20e, 20f, 20g, and 20h stacked vertically.
In FIG. 14, the three mounting panel members 20f, 20g, and 20h are stacked on the side of the mounting panel member 20d to incline the mounting panel member 20e between the mounting panel member 20d and the mounting panel member 20f. A case where a step is formed between the placing panel member 20d and the placing panel member 20f to form a simple wheelchair is shown.
The patient sits on the mounting panel member 20f, puts his / her foot on the mounting panel member 20d, and is transported while the body is supported.

The foldable stretcher according to the present invention is not limited to the emergency activities of ambulance crews, but also in places where there are narrow bent passages, for example, elderly welfare facilities, department stores, schools, stations, airports, gymnasiums, stadiums, etc. Since the patient can transport the patient with a stable posture while reducing the load, and the patient can also be transported stably, it can be used in emergency activities in these places.
In the emergency activities of ambulance crew members, stable transportation of the patient can be obtained, so cardiopulmonary resuscitation can be continued, contributing to the prevention of deterioration of the patient's condition.
In addition, in the event of a fire, earthquake, or other disaster, the person responsible for the facility can be used not only for the injured person but also for the removal of important items, etc. It can be easily used for moving and transporting goods.
