Description

Technical Field

[0001] The present invention belongs to the technical field of living equipment, and particularly relates to a comfortable air mattress for preventing pressure sores. Background Art

[0002] A pressure sore air mattress is a specially designed medical auxiliary device aimed at preventing and alleviating pressure sores that may occur in patients who are bedridden for a long time. It is particularly suitable for patients with limited mobility, unclear consciousness, postoperative recovery, fracture fixation, severe burns, and other critically ill or end-of-life care stages. Whether in medical institutions such as hospitals and nursing homes or in the home care bed environment, this air mattress plays an important role.

[0003] The existing pressure sore prevention air mattress system mainly inflates through an in-built air pump to form a soft support surface composed of multiple independent air chambers. In the inflated state, the entire air mattress surface presents a wavy design aimed at dispersing the pressure on the patient's body to reduce the risk of long-term pressure on specific parts. However, in actual use, although part of the air mattress is designed to support the patient's back while other parts are intentionally designed to avoid pressing on the patient, after long-term use, it is found that some parts of the patient's back that are in contact with and supported by the air mattress are still prone to pressure sores, and its overall use effect is not satisfactory. Summary of the Invention

[0004] In view of this, the present invention provides a comfortable air mattress for preventing pressure sores.

[0005] The technical implementation solution of the present invention is: a comfortable air mattress for preventing pressure sores, including a bed frame, an air mattress, an electric air pump, an air delivery pipe, and an intermittent support mechanism. The air mattress is connected to the top of the bed frame, and an air delivery pipe is connected between the electric air pump and the air mattress. The electric air pump can deliver air into the air mattress or extract the air in the air mattress through the air delivery pipe. An intermittent support mechanism for intermittently supporting the patient's back is provided on the air mattress.

[0006] More preferably, the intermittent support mechanism includes airbag columns, connecting pipes, air extraction pipes, air release valves, and air inlet valves. A plurality of airbag columns are evenly spaced and connected to the top of the air mattress. A communication channel is opened between the airbag columns and the air mattress, and an air inlet valve is provided at the communication channel. An air extraction pipe is arranged in the air mattress, and a plurality of air extraction ends are arranged on the air extraction pipe. The number of air extraction ends of the air extraction pipe is the same as the number of airbag columns. The air extraction ends of the air extraction pipe extend into the airbag columns and are provided with air release valves. A connecting pipe is connected between the air extraction pipe and the electric air pump. The electric air pump controls air extraction to generate negative pressure at the air extraction pipe through the connecting pipe.

[0007] More preferably, it further includes a controller. The controller is installed on the bed frame, and both the air release valve and the air inlet valve are electrically connected to the controller.

[0008] More preferably, it further includes an auxiliary turning mechanism. The auxiliary turning mechanism includes side airbags, air ducts, air inlet valves, and air outlet valves. Side airbags are connected to both sides of the bottom of the air cushion. An air duct is connected between the side airbags and the air cushion. The gas in the air cushion can enter the side airbags through the air duct. An air inlet valve is installed on the air duct, and an air outlet valve is arranged on the side airbag.

[0009] More preferably, it further includes a massage mechanism. The massage mechanism includes an air injection pipe, an air ventilation bracket, a squeezing airbag, and a hard top block. An air injection pipe is arranged inside the air cushion. The air injection pipe is connected to an electric air pump. The part of the air injection pipe extending into the air cushion is a hard pipe, and the part of the air injection pipe located outside the air cushion is a flexible pipe. A plurality of air ventilation brackets are evenly spaced on the air injection pipe. A plurality of squeezing airbags are evenly spaced on the top of each air ventilation bracket. The squeezing airbags are located inside the airbag columns, and a hard top block is connected to the top of the squeezing airbags.

[0010] More preferably, it further includes a bottom cushion plate and a heating wire. A bottom cushion plate is connected to the inner bottom of the air cushion, and a heating wire is installed on the bottom cushion plate. By controlling the operation of the heating wire, the air cushion and the airbag columns can be heated.

[0011] More preferably, it further includes a support plate. One side of the bottom of the air cushion is rotatably connected to the support plate.

[0012] More preferably, it further includes an anti-slip pad I and an anti-slip pad II. Anti-slip pads I are arranged at the bottoms of the two side airbags, and an anti-slip pad II is arranged at the bottom of the support plate. Through the dual functions of the anti-slip pad I and the anti-slip pad II, the air cushion bed can be effectively prevented from slipping during use.

[0013] Compared with the prior art, the present invention has the following advantages: 1. During the use of the present invention, the patient is supported by a plurality of airbag columns.

Detailed Embodiment

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0028] A comfortable air cushion bed for preventing pressure sores, as Figures 1-4As shown in the figure, it includes a bed frame 1, an air cushion 2, an electric air pump 3, an air delivery pipe 4 and an intermittent support mechanism. The air cushion 2 is connected to the top of the bed frame 1. An air delivery pipe 4 is connected between the electric air pump 3 and the air cushion 2. The electric air pump 3 can deliver air into the air cushion 2 or extract the air in the air cushion 2 through the air delivery pipe 4. The electric air pump 3 can be placed around the air delivery pipe 4. An intermittent support mechanism for intermittently supporting the patient's back is provided on the air cushion 2.

[0029] As Figures 2-4 shown in the figure, the intermittent support mechanism includes airbag columns 51, a connecting pipe 52, an air extraction pipe 53, a controller 56, a deflation valve 54 and an intake valve 55. A plurality of airbag columns 51 are evenly spaced and connected to the top of the air cushion 2. A communication channel is provided between the airbag column 51 and the air cushion 2, and an intake valve 55 is provided at the communication channel. Opening the intake valve 55 can enable the air in the air cushion 2 to enter the airbag column 51 through the communication channel. An air extraction pipe 53 is arranged in the air cushion 2. A plurality of air extraction ends are arranged on the air extraction pipe 53. The number of air extraction ends of the air extraction pipe 53 is the same as the number of airbag columns 51. The air extraction ends of the air extraction pipe 53 extend into the airbag column 51 and are provided with a deflation valve 54. A connecting pipe 52 is connected between the air extraction pipe 53 and the electric air pump 3. The electric air pump 3 can control the air extraction to generate negative pressure at the air extraction pipe 53 through the connecting pipe 52. At this time, when the deflation valve 54 is opened, the air in the airbag column 51 can be extracted by the air extraction pipe 53. The controller 56 is installed on the bed frame 1. Both the deflation valve 54 and the intake valve 55 are electrically connected to the controller 56.

[0030] When the air cushion 2 bed needs to be used, this air cushion 2 bed can be used. When using this air cushion 2 bed, the patient can lie between the tops of a plurality of airbag columns 51. Subsequently, the electric air pump 3 can be controlled to inflate the air cushion 2. After inflation, the intake valve 55 can be controlled to open through the controller 56, so that the air in the air cushion 2 can enter the airbag column 51, making the airbag column 51 expand, and the patient can be supported by the airbag column 51. Subsequently, the deflation valve 54 can be intermittently controlled to open through the controller 56. At this time, the electric air pump 3 can be controlled to extract air. When the deflation valve 54 deflates, the intake valve 55 is controlled to close. In this process, only the deflation valve 54 under several airbag columns 51 needs to be intermittently controlled to open, so that the airbag column 51 retracts. After retracting for a period of time, the intake valve 55 is controlled to open, and at the same time the deflation valve 54 is controlled to close. At this time, the deflation valve 54 on other airbag columns 51 is opened. Each operation only opens several deflation valves 54, specifically 5 - 10. In this way, when the patient lies on the airbag column 51, some of the airbag columns 51 can be intermittently controlled to retract, so that the airbag column 51 does not continuously press the patient, avoiding the occurrence of pressure sores.

[0031] As Figure 5 and Figure 6As shown in the figure, it further includes an auxiliary turning-over mechanism. The auxiliary turning-over mechanism includes side air bags 61, air ducts 62, air inlet valves 63 and air outlet valves 64. Side air bags 61 are connected to both the front and rear sides of the bottom of the air cushion 2. An air duct 62 is communicated between the side air bag 61 and the air cushion 2. The gas in the air cushion 2 can enter the side air bag 61 through the air duct 62, causing the side air bag 61 to expand. An air inlet valve 63 is installed on the air duct 62. Opening the air inlet valve 63 allows the gas in the air cushion 2 to enter the side air bag 61 through the air duct 62. An air outlet valve 64 is arranged on the right side of the side air bag 61. Opening the air outlet valve 64 can discharge the gas in the side air bag 61.

[0032] When a patient lies on the air cushion 2, if the patient needs to turn over, the air inlet valve 63 can be opened. For example, if the patient needs to turn to the right, the left air inlet valve 63 is opened. Conversely, if the patient needs to turn to the left, the right air inlet valve 63 is opened. After the air inlet valve 63 is opened, the gas in the air cushion 2 enters the side air bag 61 through the air duct 62, causing the side air bag 61 to expand. When the side air bag 61 expands, it will cause the air cushion 2 to stand upright, and then the patient can turn over. When turning over, since the air cushion 2 stands upright, it is more convenient for the patient to turn over. In this way, the patient can perform the turning-over operation more conveniently.

[0033] As Figure 7 and Figure 8 As shown in the figure, it further includes a massage mechanism. The massage mechanism includes an air injection pipe 71, an air ventilation bracket 72, a squeezing air bag 73 and a hard top block 74. An air injection pipe 71 is arranged in the air cushion 2. The air injection pipe 71 is communicated with the electric air pump 3. The position where the air injection pipe 71 extends into the air cushion 2 is a hard pipe, and the position of the air injection pipe 71 outside the air cushion 2 is a flexible pipe. A plurality of air ventilation brackets 72 are evenly spaced on the right side of the air injection pipe 71. A plurality of squeezing air bags 73 are evenly spaced on the top of each air ventilation bracket 72. The squeezing air bags 73 are located in the air bag columns 51. A hard top block 74 is connected to the top of the squeezing air bag 73. When the electric air pump 3 operates, it can inject air into the squeezing air bags 73 through the air injection pipe 71 and the air ventilation brackets 72, causing the squeezing air bags 73 to expand.

[0034] When the patient lies on the airbag column 51, their back will rest on the airbag column 51 with the extrusion airbag 73 arranged inside. By intermittently controlling the operation of the electric air pump 3, air is injected into the extrusion airbag 73 through the air injection pipe 71 and the ventilation bracket 72, causing the extrusion airbag 73 to expand periodically. When the extrusion airbag 73 expands, it drives the hard top block 74 to move upward, and the hard top block 74 presses against the patient's back by squeezing the airbag column 51 of the extrusion airbag 73, thereby achieving the massage effect on the patient's back. This design can not only relieve the discomfort caused by long-term lying but also promote blood circulation, helping the patient feel more comfortable when lying. In this way, the device provides an effective massage function, enhancing the patient's usage experience, and is especially suitable for patients who need to stay in bed for a long time.

[0035] As Figure 9 shown, it also includes a bottom cushion plate 8 and a heating wire 81. The bottom cushion plate 8 is connected to the inner bottom of the air cushion 2, and the heating wire 81 is installed on the bottom cushion plate 8. By controlling the operation of the heating wire 81, the air cushion 2 and the airbag column 51 can be heated, raising the temperature of the airbag column 51. When the temperature is low, the heating wire can effectively increase the temperature of the air cushion 2, ensuring that the patient is warmer when lying down, and it is suitable for use in various climate conditions. This design not only improves the patient's comfort but also provides additional warmth in a cold environment, especially suitable for patients who need to stay in bed for a long time. In this way, the effect of thermotherapy is increased, further enhancing the overall experience of the user.

[0036] As Figure 10 and Figure 11 shown, it also includes a support plate 9. The right side of the bottom of the air cushion 2 is rotatably connected to the support plate 9. By rotating the support plate 9, one side of the air cushion 2 can be lifted to assist the patient in sitting up, making it more convenient for the patient to sit up when needed. Specifically, when the patient needs to change from a lying position to a sitting position, they only need to gently rotate the support plate 9, and the right side of the air cushion 2 will be raised, providing additional support force to help the patient adjust their body position more easily. This design not only improves the patient's self-care ability and reduces the operation difficulty of the nursing staff but also effectively prevents secondary injuries that may be caused by frequent moving, enhancing the overall convenience and safety of use.

[0037] As Figure 10As shown, it further includes an anti-slip pad 91 and an anti-slip pad 92. The anti-slip pad 91 is provided at the bottom of both side airbags 61, and the anti-slip pad 92 is provided at the bottom of the support plate 9. Through the dual functions of the anti-slip pad 91 and the anti-slip pad 92, it can effectively prevent the air cushion 2 bed from slipping during use, providing a more stable support. When the patient adjusts the body position or is assisted to sit up, the anti-slip pad 91 and the anti-slip pad 92 can ensure that the air cushion 2 bed remains stable and does not move, avoiding potential safety hazards caused by sliding. This design not only improves the safety of use, but also enhances the comfort of the patient and the operation convenience of the caregiver.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
