Description

Constant pressure supporting assembly, constant pressure mattress and constant pressure bed

Technical Field

The disclosure relates to the field of medical equipment, in particular to an equal-pressure supporting assembly, an equal-pressure mattress and an equal-pressure bed.

Background

For patients with cerebrovascular diseases, osteoarticular diseases, and the like, and elderly people affected by disability or aging, long-term bed rest is required. On one hand, long-term bed rest can affect the skin of a patient and easily generate bedsore, the bedsore not only increases the treatment and nursing difficulty and cost, but also increases the pain of the patient, and the complication even can cause death of the patient; secondly, when the patient lies in bed for a long time, complications of a vascular system can be caused, namely the formation of venous thrombosis, and venous thrombosis is easy to occur due to the fact that venous blood backflow is slow and blood viscosity is increased, particularly the venous thrombosis is common to both lower limbs.

At present, the mattress pad is replaced by the air cushion clinically, the air cushion is a rectangular sealed air bag, a person directly lies on the air bag, the waist curve can be completely contacted with the air bag, the contact area of the human body and the air cushion is increased, the pressure on the skin of the bedridden human body is reduced, the pressure is not enough to seriously hinder the blood circulation in the muscle tissue of the human body, the local tissue necrosis of the bedridden person can not be caused, and therefore the bedsore of the hip, the caudal vertebra and the back can be effectively prevented.

Because the rectangular air cushion is expensive and the technical threshold is higher, the bedsore-preventing air cushion which is easy to manufacture and is arranged in the air pipe array is further provided, a plurality of sealing air pipes which are arranged in parallel are transversely arranged, a human body lies on the air pipe array after inflation, and adjacent air pipes are deflated and inflated in turn, so that the human body is stressed alternately, the compression time of the compression surface of the human body is shortened, and the possibility of bedsore caused by long-term compression of human body tissues is reduced.

Although the above products are effective in preventing bedsores, when a person directly lies on the air bag, the person lying in bed will shake on the bed surface with slight external interference; when the air cushions in the tubular array are alternately inflated and deflated, the pressed parts of the human body, which are stressed, bear higher pressure. It is obvious that a person lying on the cushions is very uncomfortable, especially with cushions in tubular arrays, because none of the healthy persons or persons who may self-express self-consciousness have chosen or used these cushions as their own daily bedding.

Moreover, the air cushion occupies the whole bed surface, so that the bed can not have other functions, which is a great obstacle to the technical progress of hospital beds and nursing beds.

Therefore, there is a need in the art of anti-decubitus devices to develop an alternative to air cushions that not only maintain the same pressure on the contact surface of the body with the bed, but also retain all the advantages of conventional mattresses.

the support bag supports the parts at two ends or the parts near the two ends of the floating horizontal grid, so that when a human body is positioned on the floating horizontal grid, different pressures are transmitted to different parts of the support bag by the concave-convex parts of the human body through the floating horizontal grid, gas and/or liquid in the support bag flows, the pressures of different parts, in contact with the support bag, of the floating horizontal grid tend to be the same, and therefore the floating horizontal grid is matched with the curved surface of the human body, in interaction with the floating horizontal grid.
The isostatic support assembly as claimed in claim 1, wherein a pad is provided on the floating bed grid to support a human body through the pad when the human body is positioned on the pad, and the pad forms a concave-convex shape fitting a curved surface of the human body.
The isostatic support assembly as claimed in claim 1 or 2, wherein said floating bedding grid comprises a plurality of bar members, each bar member being supported by said support bladder, such that the height and/or inclination of each bar member is individually adjustable by said support bladder.
The isostatic support assembly as claimed in claim 3, wherein at least two support bladders are provided, wherein at least two support bladders support each rod member near the inner side of both ends or both ends of each rod member.
The isostatic support assembly as claimed in claim 3, wherein each bar member is connected to each other by a bar connecting member such that said floating picket grid is formed as one piece.
An isostatic mattress, comprising:

a cover member having an accommodating space formed therein;

the supporting bag is arranged in the accommodating space of the cover component, and gas and/or liquid is filled in the supporting bag; and

the floating lying surface grid is arranged in the accommodating space of the cover component, and the supporting bag supports the parts at two ends or the parts near the two ends of the floating lying surface grid, so that when a human body is in contact with the cover component, different pressures are transmitted to different parts of the supporting bag by the concave-convex parts of the human body through the floating lying surface grid, so that gas and/or liquid in the supporting bag flows, the pressures of the different parts of the floating lying surface grid in contact with the supporting bag tend to be the same, and the curved surface of the human body interacted with the floating lying surface grid is matched by the cover component.
An isostatic mattress as claimed in claim 6, wherein said cover means is provided with pads which, when a person is positioned on said pads, are caused to form a relief which conforms to the curved surface of the person by said floating grid and said support cell.
An isopressure mattress as recited in claim 6, further comprising a support bladder support panel disposed within the cover member for supporting the support bladder.
An isobaric mattress according to claim 6, characterized in that said floating mat comprises a plurality of bar elements, each supported by said supporting bladders, so that the height and/or inclination of each bar element can be individually adjusted by said supporting bladders.
An isobaric mattress according to claim 9, wherein said supporting cells are provided with at least two, wherein at least two supporting cells support each bar element near the inside of two or more ends of each bar element.
An isobaric mattress according to claim 10, characterized in that each bar element is connected to each other by means of bar connecting elements so that said floating grates are formed as one piece.
An isobaric mattress according to claim 9, characterized in that a rotatable turning tube is provided on the outside of each rod element to reduce the friction generated by said floating grates by turning said turning tube with respect to the rod elements.
An isobaric support bed, characterized in that it comprises an isobaric support assembly according to any one of claims 1 to 5, or an isobaric mattress according to any one of claims 6 to 12, said isostatic support assembly or said isobaric mattress being supported on a bed frame of said isobaric bed.
The isobaric bed according to claim 13, characterized in that it comprises a back portion corresponding to the back of the human body and a buttocks portion corresponding to the buttocks of the human body, said back portion being able to rotate with respect to said buttocks portion to lift the back of the human body,

the back section and the hip section are provided with respective isopressure support assemblies or respective isopressure mattresses, respectively.
The isobaric bed according to claim 13, further comprising height adjustment members capable of adjusting the height of said floating horizontal grid so as to support said floating horizontal grid by said height adjustment members without using support of said support cell.
