Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to an inflatable mattress. Background Art

[0002] Because paralyzed patients cannot take care of themselves, long-term bed rest may cause bedsores on the back and limbs. Without the help of others, they cannot turn over, get up or even lift their legs, which brings great pain to the patients. At the same time, due to long-term lack of exercise, it may also cause atrophy of the trunk and limb muscles, which has a negative impact on future rehabilitation.

[0003] The mattresses that can assist patients to turn over in the existing technology usually can only help patients to turn over from one side to the other side, but cannot assist patients to stand up and lie down and lift their legs. Moreover, the structure is complicated and inconvenient for family members to operate. At the same time, some patients with diseases cannot lie flat due to their condition and need to be given an appropriate lying angle: for example, patients with heart failure need to rest in a semi-recumbent position. The air mattresses in the existing technology cannot provide different turning angles and cannot meet the needs of patients with different diseases. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] The following is a further detailed description of an embodiment of an inflatable bed of the utility model in conjunction with the accompanying drawings.

[0031] like Figure 1 As shown, the present application provides an inflatable mattress, comprising at least one airbag body 1, a first connecting valve group 2, a second connecting valve group 3 and an inflation and deflation valve group 4. The airbag body 1 is inflated and deflated through the inflation and deflation valve group 4, and under the action of the first connecting valve group 2 and the second connecting valve group 3, left-right unilateral inflation or upper-lower unilateral inflation is achieved to help patients turn over left-right or lie down and lift their legs.

[0032] Specifically, the circumference of the airbag body 1 can be extended and retracted in the height direction; the first connecting valve group 2 is arranged along the length direction of the above-mentioned airbag body 1 and is located in the middle of the length direction of the above-mentioned airbag body 1, and is used to separate the above-mentioned airbag body 1 into a left-flip airbag 11 and a right-flip airbag 12; the second connecting valve group 3 is arranged along the width direction of the above-mentioned airbag body 1 and is located in the middle of the width direction of the above-mentioned airbag body 1, and is used to separate the above-mentioned airbag body 1 into an upward-flip airbag 13 and a downward-flip airbag 14; the inflation and deflation valve group 4 is arranged along the circumference of the above-mentioned airbag body 1, and is used to inflate and deflate the above-mentioned left-flip airbag 11, right-flip airbag 12, upward-flip airbag 13 and downward-flip airbag 14, and flip them upward in a fan shape.

[0033] It can be understood that when the first connecting valve group 2 is opened, the second connecting valve group 3 is closed, and the inflation and deflation valve group 4 corresponding to the upward flip airbag 13 or the downward flip airbag 14 is opened, the patient's needs of standing up or lying down or lifting legs can be realized; when the first connecting valve group 2 is closed, the second connecting valve group 3 is opened, and the inflation and deflation valve group 4 corresponding to the left flip airbag 11 or the right flip airbag 12 is opened, the patient's left side or right side can be turned over.

[0034] Since the present application realizes the height adjustment of different areas of the airbag body 1 by inflating and deflating the airbag body 1, compared with the method of adjusting the height by a mechanical structure, the patient's comfort is higher, and there will be no excessive pressure in a certain part of the body causing discomfort to the patient. The force is evenly applied to various parts of the body, and the cost is lower and it is easier to store and move.

[0035] It should be noted that when the left flip airbag 11, the right flip airbag 12, the upward flip airbag 13 or the downward flip airbag 14 are opened, they are opened in a fan shape, that is, the closer the area is to the peripheral side, the higher the rising height is, and the closer the area is to the middle, the lower the rising height is.

[0036] In some optional embodiments, the inflation and deflation valve group 4 includes a plurality of one-way inflation valves and at least one one-way deflation valve. When it is necessary to inflate a corresponding area of ​​the airbag body 1, the one-way inflation valve of the corresponding area is opened and the one-way deflation valve is closed, so that the area is fan-shaped after inflation; when it is necessary to restore to the initial state, the one-way inflation valve is closed and the one-way deflation valve is opened, and the area is restored to a level state with other areas after deflation.

[0037] The structures of the one-way inflation valve and the one-way deflation valve are not described in detail here.

[0038] In some optional embodiments, the airbag body 1 may be provided with multiple ones, which are stacked in sequence along the height direction. The purpose of such arrangement is to change the lifting angle of the same area of ​​the multiple-layer airbag body 1 by inflating and deflating the air in the area. For example, if the left-turning airbag 11 of a layer of airbag body 1 can be fan-shaped and opened at an angle of 30°, then opening the left-turning airbag 11 of two layers of airbag body 1 can enable the patient to turn over at 60°. Therefore, the number of airbag bodies 1 can be arranged according to the needs of the patient to meet the needs of the patient at different turning angles.

[0039] In some optional embodiments, such as Figure 2 As shown, the airbag body 1 includes an upper body 15, an annular folded portion 16 and a lower body 17 which are sealed and connected. The upper body 15 and the lower body 17 are respectively connected to both sides of the annular folded portion 16 in the height direction, and the annular folded portion 16 is folded in the height direction.

[0040] That is to say, the airbag body 1 is fan-shapedly opened through the annular folding portion 16, and the maximum opening range of the annular folding portion 16 is the maximum angle at which the area can be flipped upwards.

[0041] In some optional embodiments, a folding portion is provided on the upper body 15 at positions corresponding to the positions of the first connecting valve group 2 and the second connecting valve group 3 .

[0042] It can be understood that the folding portion can be an arc-shaped concave structure, so that the left-flip airbag 11, the right-flip airbag 12, the upward-flip airbag 13 or the downward-flip airbag 14 can be folded more easily when they are opened.

[0043] In some optional embodiments, the first connecting valve group 2 includes a plurality of first connecting valves 21 , the second connecting valve group 3 includes a plurality of second connecting valves 31 , and both the first connecting valve 21 and the second connecting valve 31 are two-position two-way valves.

[0044] Specifically, the first connecting valve group 2 includes a first isolating member arranged in the middle of the length direction of the airbag body 1 and a first connecting valve 21 installed on the isolating member, and the second connecting valve group includes a second isolating member arranged in the middle of the width direction of the airbag body 1 and a second connecting valve 31 installed on the isolating member. By pressing the first connecting valve 21 and the second connecting valve 31, the left flip airbag 11 and the right flip airbag 12, and the upward flip airbag 13 and the downward flip airbag 14 are connected or isolated.

[0045] By providing the first connecting valve 21 and the second connecting valve 31, the connection or isolation of different areas of the airbag body 1 is achieved, thereby taking into account the functions of turning over, lying down and raising the legs of the patient.

[0046] In some optional embodiments, such as Figure 5 As shown, the inflatable mattress also includes a cover body 5, which is arranged outside the airbag body 1 and includes an upper cover body and a lower cover body. The upper cover body is connected to the top surface of the airbag body 1, and the lower cover body is connected to the bottom surface of the airbag body 1. The upper cover body and the lower cover body are detachably connected along the circumferential side.

[0047] It can be understood that the cover body 5 can not only provide protection for the airbag body 1 to prevent the airbag from being damaged due to external sharp objects and affecting its use, but also fix the area that does not need to be inflated through the detachable connection between the upper cover body and the lower cover body on the circumferential side, and ensure that the corresponding area of ​​the airbag body 1 can be maintained in a horizontal state after deflation through the fixation between the upper cover body and the lower cover body, which will not affect the patient's normal lying.

[0048] Furthermore, the upper cover body and the lower cover body are detachably connected via an annular first zipper 51 and an annular second zipper 52, the first zipper 51 is used to separate or connect the upper cover body and the lower cover body at both ends in the width direction, and the second zipper 52 is used to separate or connect the upper cover body and the lower cover body at both sides in the length direction.

[0049] In this example, the first zipper 51 and the second zipper 52 are spaced apart in the height direction. Opening the first zipper 51 separates the upper cover body and the lower cover body corresponding to the left-flip airbag 11 or the right-flip airbag 12 area, so that when the left-flip airbag 11 or the right-flip airbag 12 is inflated, no interference will be caused, while ensuring that other uninflated areas remain in their initial state.

[0050] In some optional embodiments, a buffer pad of a set thickness is provided in the upper cover body, and the upper surface of the buffer pad is uneven, so as to reduce the pressure area of ​​the patient's skin.

[0051] It can be understood that the cushion can reduce the downward pressure on the patient when turning over to this area and improve the comfort of the patient when using it.

[0052] In some optional embodiments, a plurality of supporting structures 6 are further provided in the airbag body 1 , and the supporting structures 6 can be extended and retracted along the height direction of the airbag body 1 .

[0053] It can be understood that the inflation and deflation valve group 4 can realize the inflation and deflation of the corresponding area of ​​the airbag body 1 through the inflation pump and the exhaust pump. In the case of no use conditions, the support structure 6 is set and matched with the cover body 5, so that the inflation and deflation of the airbag body 1 can be realized without the inflation pump and the exhaust pump. The following is a detailed description:

[0054] When the patient needs to be turned over to the left side, the first zipper 51 is opened to separate the upper and lower mask bodies on the left side in the width direction, and the inflation and deflation valve group 4 at the left-turned airbag 11 is opened. At this time, the support structure 6 is no longer constrained by the mask body and begins to stretch. The left-turned airbag 11 is stretched open by the support structure 6 and generates negative pressure with the outside. The gas enters the left-turned airbag 11 from the inflation and deflation valve group 4 until the support structure 6 stops stretching. When the left-turned airbag 11 needs to be restored to its initial state, the left-turned airbag 11 is pressed down to compress the support structure 6, and the gas is discharged from the inflation and deflation valve group 4. The first zipper 51 is closed to keep the support structure 6 under downward pressure.

[0055] Therefore, the inflation and deflation valve group 4 can be a switchable valve at this time, and the gas can enter and exit the valve by changing the volume change of the corresponding area of ​​the airbag body 1.

[0056] Preferably, the supporting structure 6 is a telescopic spring, both ends of which are respectively connected to the inner wall of the airbag body 1 .

[0057] In other embodiments, the support structure 6 may also be a hydraulic spring whose initial state is a fully extended state. The compressed hydraulic spring accumulates elastic potential energy to prepare for the release of the elastic potential energy after the zipper is opened to inflate the airbag.

[0058] In some optional embodiments, the elastic potential energy of the plurality of telescopic springs gradually decreases as they approach the first connecting valve group 2 and the second connecting valve group 3 .

[0059] Preferably, the telescopic springs are arranged in a matrix in the airbag body 1, and the telescopic springs near the peripheral side have a large stretchability, while the telescopic springs near the middle have a small stretchability.

[0060] The purpose of such arrangement is to cooperate with the left flip airbag 11, the right flip airbag 12, the upward flip airbag 13 or the downward flip airbag 14 to open in a fan shape.

[0061] The following example illustrates how the air mattress of the present application can be used to achieve the patient's turning over or getting up from the left side.

[0062] When the patient needs to turn over to the left side, the first zipper 51 is opened to separate the upper cover body and the lower cover body on the left side in the width direction, and the inflation and deflation valve group 4 at the left-turning airbag 11 is opened. At this time, the support structure 6 is no longer constrained by the cover body and begins to stretch. The left-turning airbag 11 is stretched out by the support structure 6 and generates negative pressure with the outside. The gas enters the left-turning airbag 11 from the inflation and deflation valve group 4 until the support structure 6 stops stretching and the left-turning airbag 11 flips up to a set angle, and the patient turns over to the left side; when the patient needs to stand up or lie down, the second zipper 52 is opened to separate the upper cover body and the lower cover body on the upper side in the length direction, and the inflation and deflation valve group 4 of the upward-turning airbag 13 is opened. At this time, the support structure 6 is no longer constrained by the cover body and begins to stretch. The upward-turning airbag 13 is stretched out by the support structure 6 and generates negative pressure with the outside. The gas enters the upward-turning airbag 13 from the inflation and deflation valve group 4 until the support structure 6 stops stretching and the upward-turning airbag 13 flips up to a set angle, and the patient stands up or lies down.

[0063] The inflatable mattress of the present application is inflated and deflated by an inflation and deflation valve group 4, and under the action of the first connecting valve group 2 and the second connecting valve group 3, it can be inflated on one side or on the upper and lower sides, so as to help the patient turn over or lie down and lift his legs. Compared with the height adjustment method using a mechanical structure, the patient's comfort is higher, and there will be no discomfort caused by excessive pressure in a certain part of the body. The force is evenly applied to all parts of the body, and the cost is lower, and it is easier to store and move. By setting a multi-layer airbag body 1, the lifting angle of the area can be changed to meet the needs of the patient's different turning angles. By setting a cover body 5, not only can the airbag body 1 be protected to avoid damage to the airbag due to external sharp objects, which affects the use, but also the upper cover body and the lower cover body can be detachably connected on the peripheral side to fix the area that does not need to be inflated, and also ensure the airbag is inflated. After being deflated, the corresponding area of ​​the airbag body 1 can be kept in a horizontal state by fixing the upper cover body and the lower cover body, and will not affect the patient's normal lying; by setting the first zipper 51 and the second zipper 52, the corresponding area of ​​the airbag body 1 can be opened in a fan shape without causing interference, while ensuring that other uninflated areas remain in their initial state; by setting a buffer pad, the downward pressure of the patient when turning over to this area can be reduced, and the comfort of the patient when using it can be improved; by setting a support structure 6 and cooperating with the cover body 5, the inflation and deflation of the airbag body 1 can be achieved without an inflation pump and an exhaust pump; by gradually reducing the elastic potential energy of the multiple telescopic springs as they approach the first connecting valve group 2 and the second connecting valve group 3, the left-turning airbag 11, the right-turning airbag 12, the upward-turning airbag 13 or the downward-turning airbag 14 can be opened in a fan shape.
