Description

Bed for a patient using plastic bottle

The present invention relates to a patient bed using a plastic bottle, and more particularly to a patient bed using a plastic bottle that the mattress of the bed can be smoothly folded along the unit frames.

Generally, a bed is divided into a hard stone bed, a latex bed with a cushion, a spring bed, and the like, and various kinds of functions are added to the bed.

Cushion beds, such as latex beds and spring beds, are usually composed of a frame supporting the entire bed and a mattress seated on the frame and having elasticity.

Long-term use of such a cushion bed, such as a latex bed or a spring bed, will not only reduce the elasticity of the mattress as the spring or latex elastic member is continuously pressed, but also the concentrated and continuously pressed part of the mattress of the bed The problem is that the elasticity is reduced as it sags. Therefore, conventionally, when the mattress of the bed is used for a certain period of time and sag occurs in a specific part, the mattress is flipped or repositioned by changing the position of the mattress.

In order to solve this problem, the present applicant, the patent registration No. 0377326 (multi-cell tube and its manufacturing method), the patent registration No. 0449994 (multi-air mat), Utility Model Registration No. 0305992 (mattress using latex and air tube ), Patent Registration No. 0510006 (Mattress), Patent Publication No. 10-2005-0104571 (Multi-chamber) (Publication date: November 03, 2005), Patent Registration No. 0721440 (Air for air mat using blow molding) Chamber) and Patent No. 0721438 (air mat using blow molded air chamber and its manufacturing method).

These inventions relate to an air mattress capable of simultaneously filling air into a plurality of air chambers, and thus connecting an air injection device to the inlets with a plurality of air chambers arranged horizontally. The device made it possible to simultaneously inject and exhaust air to multiple air chambers.

Bed production using such an air chamber is as follows.

First, a plurality of air chambers are arranged horizontally and an inner cushion is placed therebetween. An air supply pipe is connected to the inlets of the air chambers, a guide rail is positioned around the air chambers, and a comfort layer is seated thereon. The entire air chamber, including the guide rail and comfort layer, is covered with a mattress cover. The air mattress manufactured as described above is seated on the frame of the bed and covers the bed and the air mattress and the frame.

By the way, such a conventional air mattress for the bed can not be applied to the patient bed because it does not fold smoothly, the reason is as follows.

The patient bed is provided with a plurality of unit frames that can be adjusted angle. The angle adjustment of the unit frame may be made automatically by the lifting of the screw shaft by the rotation of the drive motor or the operation of the link, and may be made manually by lifting the screw shaft or by operating the links when the operator rotates the handle by hand. Since one mattress is fixed on the plurality of unit frames, when the angle of the unit frames is adjusted, the mattress fixed thereto is bent along the same.

Patients with uncomfortable behavior can watch TV, read, relax or receive treatment in a comfortable posture by raising one side of the mattress or allowing various parts of the mattress to be bent while lying in the patient bed described above.

However, the above-described air mattresses developed by the applicant have not been smoothly folded along the unit frames because of the hoses connecting the air chambers and the rigid guide rails.

That is, when a part of the air mattress is folded to the comfort layer side, the distance between two adjacent air chambers of the folding part should be opened to each other. However, the two air chambers were not opened smoothly by the hoses connected between them, and when the air mattress was folded forcibly in such a state, the hose and its connection part were also damaged.

In addition, in order to fold the air mattress described above, the guide rail embedded therein must also be folded therewith, and as the guide rail is folded, the bent portion is increased in density, and the air mattress is not further folded as the density is increased.

An object of the present invention for solving the above problems is to provide a patient bed using a plastic bottle so that the mattress of the bed can be folded smoothly along the unit frames.

Patient bed using a plastic bottle of the present invention for achieving the above object, Bed frame is installed a plurality of unit frames connected to each other to be bent; A plurality of plastic bottles seated on the unit frames and having a self-elasticity so that air is discharged or sucked while being deformed or restored according to an external force; Inner cushions provided between a plurality of the plastic bottles to absorb the pressure applied to the plastic bottles and to help the plastic bottles to be restored; A guide rail installed around the plastic bottles connected by a hose and having bending guide parts formed to be bent along the unit frames; A comfort layer seated on the plastic bottles; And a mattress cover surrounding the plastic bottles, the guide rail and the comfort layer.

Another feature of the patient bed using the plastic bottle of the present invention is that the plastic bottle has a bellows portion formed around the two corresponding surfaces such that two opposite surfaces of each of the plastic bottles face each other.

Another feature of the patient bed using the plastic bottle of the present invention, the bending guide portion, is formed inside the bent portion of the guide rail is deformed during bending of the guide rail while bending guide holes or notches, In either case, the incision is made.

Another feature of the patient bed using the plastic bottle of the present invention, the mattress cover is made of any one of the pleated cloth, spandex so as to stretch according to the bending of the mattress.

In the present invention as described above, the bending induction hose is connected to the portion of the hoses connecting the plastic bottles opposed to the bending portion of the mattress. Therefore, even when the mattress is folded, the two adjacent plastic bottles are spaced apart from each other, so that the bending induction hose to compensate for the gap is not hindered by the hose folding of the mattress or damage to the hose.

In addition, among the hard guide rails provided around the plastic bottles, a bending guide portion is formed at a portion opposite to the bending portion of the mattress. Therefore, when the mattress is folded, the guide rail is easily folded while the bending guide portion is deformed. Therefore, an air mattress with plastic bottles can be applied to the patient's bed.

In the present invention, the plastic bottle constituting the mattress is formed by the blow molding of the bottle body and the inlet without a fusion part, so that the air leakage problem of the fusion is solved, and the manufacturing process is very simple, thus reducing the product cost. However, they can be mass-produced, so that good products can be supplied to many people at low cost.

In addition, since the bellows portion, which is a space compression means, is formed in the bottle body so that two corresponding surfaces facing each other of the bottle body are folded or unfolded, the bottle is stored in a warehouse or container for storing or transporting the plastic bottle. By compressing the bellows portion of the body to minimize the volume, it is possible to load the maximum plastic bottle in a predetermined space.

Specific features and advantages of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawings.

1 is a schematic side view showing a patient bed using a plastic bottle of the present invention, Figure 2 is a schematic perspective view showing the interior of the bed mattress, Figure 3 is a schematic side view showing the interior of the bed mattress. 4 is a schematic side view showing a state in which the mattress of the bed is bent, FIG. 5 is a schematic side view showing the inside of FIG. 4, and FIGS. 6 to 8 are partially enlarged side views showing the bent portions.

The patient bed using the plastic bottle of the present invention is composed of a bed frame (1) for supporting the entire bed and the mattress 10 seated on the frame (1) and the outer surface of the mattress (10) It may also be wrapped with a cover (not shown).

The bed frame 1 forms a frame of the bed, supports the mattress 10 of the bed, and is provided with a supporting leg 2. At the bottom of the support leg (2) is provided a wheel (3) to transport the bed. Frame 1 of such a bed may be provided in various ways according to the design of the bed.

The upper part of the patient bed frame 1 is provided with a plurality of unit frames (4) capable of adjusting the angle. The unit frame 4 is composed of a first unit frame 5, a second unit frame 6, a third unit frame 7, and a fourth unit frame 8. It is fixed to the bed frame (1).

The form of the unit frame 4 is not limited to the above. That is, other unit frames other than the third unit frame 7 may be fixed to the bed frame 1, and the number of the unit frames 4 may be provided less than four or more than four.

The angle adjustment of the unit frame (4) may be made automatically by the lifting of the screw shaft by the rotation of the drive motor or by the operation of the links, and if the operator rotates the handle by hand, the screw shaft may be lifted or the link is operated manually. have. Since one mattress 10 is fixed above the plurality of unit frames 4, when the angle of the unit frames 4 is adjusted, the mattress 10 fixed thereto is bent along the same.

The mattress 10 here is a plastic bottle 11, inner cushions 14 therebetween, guide rails 24 around the plastic bottles 11, and a comfort layer 17 above the plastic bottles 11. (comport layer), and the mattress cover 19 surrounding the circumference.

The plastic bottle 11 is seated on the supporting frame 1 of the whole bed, and has its own elasticity and blow molding so that air is discharged or sucked while being deformed or restored according to external force.

The plastic bottle 11 is blow molded so as to have a closed space, and the entire outer circumferential surface of the plastic bottle 11 is blow molded integrally with the bottle body 12 to externally space the space of the bottle body 12. It consists of an inlet 13 to connect with. A hose 15 is connected to the inlets 13 and the air pump (not shown) of the plastic bottle 11.

Here, a bending induction hose 16 is connected to a portion of the hoses 15 connecting the plastic bottles 11 opposite to the bending portion of the mattress 10. The bending induction hose 16 is formed longer in length than the hoses 15 of the other portions connecting the plastic bottles 11, and thus the mattress 10 is folded and the two adjacent plastic bottles 11 are separated. Even if the gaps are spaced apart, the bending induction hoses compensate for the gaps. Therefore, the conventional problem that the plastic bottle of the bent portion is not opened properly and the folding of the mattress is hindered, or the conventional problem that the connection part of the hose is broken when the mattress is bent is solved.

Since the plastic bottle 11 is blow molded, the bottle body 12 and the injection port 13 are integrally formed at once without the fusion portion, so that the air leakage problem of the fusion portion is solved, and the manufacturing process thereof is very simple. Not only will the cost of the product be reduced, but also the mass production will be possible, which will enable the supply of superior products at low prices to many people.

On the other hand, the plastic bottle 11 formed by the blow mold, the material is made of a non-elastic material, when the pressure is applied to the plastic bottle 11 in the state filled with air, the shape is deformed to some extent to remove the pressure If the material can be restored to its appearance again. As a material of the plastic bottle 11 that satisfies these conditions, it may be made of a polyethylene-based (PE) material mainly used for manufacturing a bucket, a food packaging container, or the like.

The guide rail 24 is installed around the plastic bottles 11 and has bending guide parts formed to be bent along the unit frames 4. Here, the bending induction part is formed inside the bent portion of the guide rail 24 and is formed by the bending induction hole 24a which induces the bending while being deformed when the guide rail 24 is bent.

Since the bending guide hole 24a is formed in a portion of the guide rail 24 opposite to the bent portion of the mattress 10, the density of the guide rail 24 in that portion is smaller than that of other portions. Therefore, when the mattress is folded, the guide rail 24 is easily folded while the portion of the bending guide hole 24a having a smaller density than the other part is deformed.

The guide rail 24 may be made of a material such as a rigid polyurethane foam (polyurethane foam).

10 and 11 are schematic front views illustrating various embodiments of the bending guide part, and the bending guide part of the guide rail 34 may be formed in the shape of the notch part 34a as shown in FIG. 10, and the guide rail 44 as shown in FIG. 11. The bending guide portion of) may be formed in the form of incision line (44a).

Therefore, the bending guide portion of the guide rails 24, 34, 44 of the present invention may be made of any one of the bending guide hole 24a, the notch 34a, and the cut line 44a.

The comfort layer 17 is seated on the plastic bottles 11 and may be made of soft latex, urethane foam, memory foam, or the like.

The mattress cover 19 wraps the plastic bottles 11, the guide rails 24, and the comfort layer 17 thereon to form a mattress 10.

The mattress cover 19 may be made of a cotton material, made of a good elastic material so that the mattress 10 is smoothly stretched when it is bent. When the mattress cover 19 is made of a good elastic material, it may be made of a material such as wrinkled cloth or excellent spandex elasticity.

The mattress cover 19 is preferably made of an antibacterial cloth to prevent the penetration of bacteria or foreign matter into the mattress (10).

The patient bed using the plastic bottle of the present invention in this configuration arranges a plurality of plastic bottles 11 horizontally and positions the inner cushions 14 therebetween. Inlets 13 of the plastic bottles 11 connect a hose 15, and an air pump (not shown) is connected to the hose 15. The inner cushion 14 is provided between the plurality of plastic bottles 11 to absorb the pressure applied to the plastic bottles 11 and to help the plastic bottles 11 to be restored.

Here, a portion of the hoses 15 connecting the plastic bottles 11 to the bending portion of the mattress 10 is connected to the bending induction hose 16 formed longer than the hoses 15 of the other portions. do. Thus, even when the mattress 10 is folded, even if the two adjacent plastic bottles 11 are spaced apart from each other, the bending induction hose 16 compensates for the gap.

The guide rails 24 are installed around the plastic bottles 11 coupled as described above. The guide rail 24 is formed with a bending guide hole 24a which is a bending guide part so that the mattress 10 is easily bent when the mattress 10 is bent along the unit frames 4. Therefore, when the mattress 10 is folded, the guide rail 24 is easily folded while the portion of the bending guide hole 24a having a smaller density than the other part is deformed. And the comfort layer 17 is seated on the upper portion of the plastic bottle (11).

On the other hand, the guide rail 24 may be formed with a bending guide hole 24a as a bending guide portion, but may be formed with notches 34a or cut lines 44a as described with reference to FIGS. 10 and 11. The bending guide part such as the notch part 34a or the incision line 44a is guided so that the guide rails 34 and 44 are bent smoothly while being opened to each other when the guide rails 34 and 44 are bent.

When the comfort layer 17 is seated on the upper part of the plastic bottles 11, the mattress cover 19 is put around them. The mattress cover 19 may be made of a cotton material, but may be made of a material such as pleated cloth, spandex, or the like so that the mattress 10 may be stretched and bent when the mattress 10 is bent, and infiltration of bacteria or foreign matter into the mattress 10. It is made of antibacterial cloth so that it is prevented.

When the mattress 10 is completed, the mattress 10 is seated on the frame 1 and the mattress 10 and the unit frame 4 are fixed with a string. That is, both ends of the first unit frame 5 and the corresponding portions of the mattress 10 corresponding thereto are connected, and both ends of the third unit frame 7 and the corresponding portions of the mattress 10 corresponding thereto are connected, and One end of the four unit frame 8 and the end of the mattress 10 corresponding thereto are connected.

In this way, when the mattress 10 is fixed to the unit frames 4, the mattress 10 is bent together when the unit frames 4 are bent.

Patient bed using the plastic bottle of the present invention has the following advantages.

First, a bending induction hose 16 is connected to a portion of the hoses 15 connecting the plastic bottles 11 opposite to the bending portion of the mattress 10. Therefore, even when the mattress 10 is folded and the gap between the two adjacent plastic bottles 11 are mutually widened, the bending induction hose 16 is to compensate for the gap between the gaps of the mattress 10 is hindered by the hose 15 or No damage is caused to the hose 15.

Second, in the guide rails 24, 34 and 44 provided around the plastic bottles 11, the portions opposed to the bent portions of the mattress 10 are bent guide holes 24a so as to have a smaller density than the other portions. May be formed, the notch 34a may be formed, or the cut line 44a may be formed. Therefore, when the mattress 10 is folded, the portion of the bending guide hole 24a having a smaller density than the other portion is deformed, or the notches 34a or the incision line 44a are opened and the guide rails 24, 34 and 44 are opened. ) Is easily folded. Therefore, the air mattress 10 in which the plastic bottles 11 are embedded may be applied to the patient bed.

Third, the plastic bottle 11 constituting the mattress 10 is integrally molded without blown by the bottle body 12 and the injection port 13 by blow molding. Therefore, the air leakage problem of the welded part is solved, and the manufacturing process is very simple, not only the product cost is reduced, but also the mass production is possible, thereby providing excellent products at a low price to many people.
