Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a clinical adaptive medical mattress based on giant electrorheological fluid and its control system. Background Technology

[0002] Medical mattresses are core auxiliary equipment in the medical and nursing field, widely used in hospitals, rehabilitation centers, and home care settings. They primarily provide body support, posture adaptation, and basic nursing care for bedridden patients. With the increasing aging population, the growing demand for more refined medical and nursing care, and the clinical emphasis on patient comfort and nursing safety, medical mattresses have become an important medical accessory for optimizing nursing processes and reducing nursing stress. Their technological applications and adaptability to various scenarios continue to receive industry attention.

[0003] An existing patent (publication number: CN203576802U) discloses a mattress for preventing pressure sores in long-term bedridden patients. The air mattress is composed of multiple air bladders arranged side by side, each of which is equipped with an exhaust pipe. The exhaust pipe is equipped with a solenoid valve controlled by a controller. When the solenoid valve on a certain air bladder is opened, the gas in that air bladder is discharged through the exhaust pipe and instantly collapses. The collapsed air bladder is then re-inflated by the air bladder of the next level. The air bladder between the deflation end and the air intake end continuously undergoes air intake and deflation cycles. The air bladders alternately inflate and collapse, avoiding prolonged pressure on the same part of the patient's body and preventing pressure sores.

[0004] Although the application allows the gas in a bladder to be released through the exhaust pipe and then instantly deflate after being opened by the solenoid valve on one of the bladders, and the deflated bladder to be re-inflated by the bladder of the next level, thus achieving the alternating opening and closing of the bladders and providing intermittent support to the human body, the pressure is concentrated at the contact points when the air cushion is in use, which can easily lead to discomfort at the contact points.

[0005] An existing patent (publication number: CN114631999B) discloses a combined intelligent massage mattress. Due to the use of a hammer disc and massage hammer, the overall massage area can be expanded, so that the entire waist or back can be massaged evenly, increasing comfort. Due to the sliding cooperation between the double gear and the fixed rack, the sliding block can be made to reciprocate linearly, thereby driving the entire massage mechanism to move. The overall massage position can be adjusted according to the needs of the human body, adapting to different people and making it more humane.

[0006] Although the application uses a vibrating motor to generate force, causing the hammer disc to vibrate, and the internal massage hammer to massage the human body under the action of vibration, and the massage mechanism uses a reciprocating motor to drive the reciprocating connecting parts to move the massage mechanism to massage different parts of the human body, the adjustment method of the massage mechanism of this patent has obvious shortcomings. The position of the massage mechanism needs to be adjusted every time it is used, which is inconvenient. Summary of the Invention

[0007] The purpose of this invention is to provide a clinically adaptive medical mattress based on giant electrorheological fluid and its control system, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a frame including a base shell, an intermittent adjustment mechanism disposed on the base shell, and a support assembly movably disposed on the base shell. The support assembly includes a bladder, with one-way valves installed at both ends of the bladder, and the two one-way valves having opposite output directions. The support assembly also includes a vibration device disposed within the bladder, with a massage ball installed at the top and a pressure sensor installed at the bottom.

[0009] When the patient lies on the bladder, the bladder will be compressed, and some of the gas inside the bladder will be released through the one-way valve until the bladder comes into contact with the massage ball. The massage ball will transmit the pressure it receives to the pressure sensor. After the pressure sensor detects the signal, the vibration device will be activated, which will drive the massage ball to vibrate, thereby massaging the body through the vibrating massage ball. The vibration device and massage ball will not be activated when they are not compressed, so there is no need for manual adjustment of the massage position and there will be no ineffective massage.

[0010] Preferably, the intermittent adjustment mechanism includes a drive motor, which is mounted on the side of the bottom shell. The output end of the drive motor is connected to a rotating shaft via a coupling. The other end of the rotating shaft is rotatably connected to the bottom shell. A first eccentric block and a second eccentric block are fixed on the rotating shaft.

[0011] The drive motor can be a miniature geared motor with a large output torque. Multiple drive motors are set, and they need to be synchronized by a controller. The rotating shaft is made of stainless steel. The first and second eccentric blocks are evenly distributed along the axial direction of the rotating shaft. The drive motor drives the rotating shaft. The rotation of the rotating shaft will drive the first and second eccentric blocks to rotate. The rotation of the first and second eccentric blocks will cause the U-shaped mounting plate and the bladder set above them to move up and down periodically, so as to provide intermittent support for the human body, avoid long-term pressure on the same part of the human body, and reduce the risk of pressure sores.

[0012] Preferably, the device further includes a guide assembly disposed on the bottom shell. The guide assembly includes a guide seat fixed to the inner side of the bottom shell, and a guide plate slidably connected to the guide seat. The guide plate is connected to the end of the bladder. The guide assembly also includes a U-shaped mounting plate fixed to the guide plate and fixed to the bottom of the bladder.

[0013] The guide seat is fixed to the inside of the bottom shell by bolts. The guide plate can slide up and down on the guide seat. The guide seat, guide plate and U-shaped mounting plate are used to limit the movement trajectory of the bladder to ensure that it moves in the vertical direction in order to intermittently support the human body.

[0014] Preferably, the bottom shell has ventilation holes on its side, the inner contour of which is elongated and evenly distributed on both sides of the bottom shell. The ventilation holes allow the inside of the bottom shell to communicate with the outside, preventing the inside of the bottom shell from overheating or becoming excessively humid.

[0015] Preferably, the bottom shell is fixed with straps on its side. The straps are made of high-strength nylon and have Velcro sewn at both ends. The Velcro is used to connect the straps, thereby reinforcing the bottom shell and reducing the risk of it shifting on the bed.

[0016] Preferably, a breathable sponge layer is fixed to the bottom of the bottom shell, and a silicone anti-slip pad is fixed to the bottom of the breathable sponge layer. The breathable sponge layer has a high density and a high thickness. The breathable sponge layer is fixed to the bottom of the bottom shell by spraying adhesive, and the silicone anti-slip pad is fixed to the bottom surface of the breathable sponge layer by spraying adhesive. The breathable sponge layer cushions the overall vibration of the mattress and enhances breathability, while the silicone anti-slip pad increases the friction with the bed frame, strengthens the anti-slip effect, and prevents the mattress from shifting.

[0017] Preferably, the device also includes an electrorheological fluid pad, which is disposed on the frame. The electrorheological fluid pad includes a flexible wrapping material, in which the electrorheological fluid material is disposed, and an insulating material is disposed on the outside of the electrorheological fluid material. The flexible wrapping material also needs to be made of insulating material. The viscosity of the electrorheological fluid material can be controlled by electricity, and the softness and hardness of the electrorheological fluid material can be adjusted to suit different patients and improve the comfort of patients.

[0018] In addition, when the electrorheological fluid material is switched to a rigid state, the electrorheological fluid pad becomes rigid as a whole. At this time, the electrorheological fluid pad can support the human body and has a strong load-bearing capacity. It can be used directly as a stretcher. Medical staff can lift the electrorheological fluid pad to directly complete the non-contact horizontal displacement of patients on the operating table, transfer bed, and hospital bed. This completely eliminates the risk of incision traction caused by traditional manual patient handling and the shearing damage caused by friction of mechanical devices. At the same time, it reduces the manpower required for bed transfer operations, significantly reduces the incidence of postoperative transfer-related complications, and improves the turnover efficiency of ICU or operating room.

[0019] A control system includes the following steps: S1: The control system is activated. The pressure sensor monitors the pressure distribution on the bladder. After the patient lies on the bladder, the pressure sensor feeds back the captured pressure signal to the control system. The control system then activates the vibration device inside the bladder. The vibration device drives the massage ball on top to vibrate, massaging the contact area between the patient and the bladder.

[0020] S2: The drive motor is started at regular intervals by the control system. The working drive motor drives the first eccentric block and the second eccentric block to rotate 180 degrees through the rotating shaft. The U-shaped mounting plate on the first eccentric block and the bladder and the U-shaped mounting plate on the second eccentric block will move up and down relative to each other, so that the bladder provides intermittent support to the human body.

[0021] S3: When the human body leaves the capsule, the capsule will reset. During the reset process, external air is drawn in through the one-way valve on the other side, thereby forming a directional airflow circulation, accelerating the exchange of air between the inside of the bottom shell and the outside, and removing the heat accumulated in the area where the capsule contacts the human body.

[0022] S4: By controlling the electrorheological fluid material through the regulation system, the electrorheological fluid material is switched to a hard state. In this state, the electrorheological fluid pad can support the human body and can be used directly as a stretcher.

[0023] The technical effects and advantages of this invention are as follows: 1. The intermittent adjustment mechanism of this invention drives the bladder to move up and down periodically. The one-way valves at both ends of the bladder output in opposite directions. When the bladder is compressed and contracts, the internal air is quickly discharged through one-way valve on one side. During the reset process, external air is drawn in through the other one-way valve, forming a directional airflow circulation. This accelerates the exchange of air between the bottom shell and the outside air, and removes the heat accumulated in the area where the bladder contacts the human body. This avoids the stuffy and damp skin caused by prolonged bed rest. This heat dissipation method does not require additional power and is achieved naturally by intermittent mechanical movement, continuously keeping the contact area dry and relieving discomfort in the contact area.

[0024] 2. During intermittent support, the capsule of this invention is in close contact with the human body. When the weight of the human body causes the capsule to deform and compress the pressure sensor at the bottom, the pressure sensor captures the pressure signal in real time and feeds it back to the control system. The control system activates the vibration device inside the capsule, which drives the massage ball at the top to vibrate and massage the pressure area. There is no need to manually adjust the massage position. The massage function is synchronized with the intermittent support and is triggered only when the human body is under pressure, avoiding ineffective vibration interference. The massage and heat dissipation functions of this device are synchronized during intermittent support. The heat dissipation function reduces the temperature of the contact area, and the massage function relieves the discomfort caused by pressure on the contact area. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] This invention provides, for example Figures 1 to 7The clinical adaptive medical mattress and its control system based on giant electrorheological fluid shown includes a frame 1, which includes a bottom shell 101. The bottom shell 101 has ventilation holes 102 on its side. The inner contour of the ventilation holes 102 is elongated. The ventilation holes 102 are evenly distributed on both sides of the bottom shell 101. The ventilation holes 102 can connect the inside of the bottom shell 101 with the outside, thus preventing the inside of the bottom shell 101 from overheating or becoming excessively humid.

[0029] The bottom shell 101 is fixed with straps 103 on its side. The straps 103 are high-strength nylon straps with Velcro sewn at both ends. The Velcro is used to connect the straps 103, thereby reinforcing the bottom shell 101 and reducing the risk of it shifting on the bed.

[0030] A breathable sponge layer 104 is fixed to the bottom of the bottom shell 101, and a silicone anti-slip pad 105 is fixed to the bottom of the breathable sponge layer 104. The breathable sponge layer 104 is a high-density breathable sponge layer. The breathable sponge layer 104 is fixed to the bottom of the bottom shell 101 by spraying adhesive, and the silicone anti-slip pad 105 is fixed to the bottom surface of the breathable sponge layer 104 by spraying adhesive. The breathable sponge layer 104 cushions the overall vibration of the mattress and enhances breathability. The silicone anti-slip pad 105 increases the friction with the bed frame, strengthens the anti-slip effect, and prevents the mattress from shifting.

[0031] Intermittent adjustment mechanism 3 is disposed on the bottom shell 101. The intermittent adjustment mechanism 3 includes a drive motor 301, which is mounted on the side of the bottom shell 101. The output end of the drive motor 301 is connected to a rotating shaft 302 via a coupling. The other end of the rotating shaft 302 is rotatably connected to the bottom shell 101. A first eccentric block 303 and a second eccentric block 304 are fixed on the rotating shaft 302.

[0032] The drive motor 301 can be a miniature geared motor with a large output torque. Multiple drive motors 301 are provided, and they need to be synchronized with each other through a controller. The rotating shaft 302 is made of stainless steel. The first eccentric block 303 and the second eccentric block 304 are evenly distributed along the axial direction of the rotating shaft 302. The drive motor 301 is used to drive the rotating shaft 302. The rotation of the rotating shaft 302 will drive the first eccentric block 303 and the second eccentric block 304 to rotate. The rotation of the first eccentric block 303 and the second eccentric block 304 will cause the U-shaped mounting plate 403 and the bladder 201 set above it to move up and down periodically, so as to provide intermittent support for the human body, avoid long-term pressure on the same part of the human body, and reduce the risk of pressure sores.

[0033] Support assembly 2 is movably mounted on bottom shell 101. Support assembly 2 includes a bladder 201. One-way valves 202 are installed at both ends of the bladder 201, and the output directions of the two one-way valves 202 are opposite. Support assembly 2 also includes a vibration device 203, which is disposed inside the bladder 201. A massage ball 204 is installed on the top of the vibration device 203, and a pressure sensor 205 is installed on the bottom of the vibration device 203.

[0034] When the patient lies on the bladder 201, the bladder 201 will be compressed, and some of the gas inside the bladder 201 will be discharged through the one-way valve 202 until the bladder 201 contacts the massage ball 204. The massage ball 204 will transmit the pressure it receives to the pressure sensor 205. After the pressure sensor 205 detects the signal, the vibration device 203 will be activated. The vibration device 203 can drive the massage ball 204 to vibrate together, thereby massaging the human body through the vibrating massage ball 204. The vibration device 203 and the massage ball 204 will not be activated when they are not compressed, so there is no need for manual adjustment of the massage position and there will be no ineffective massage.

[0035] The guide assembly 4 is disposed on the bottom shell 101. The guide assembly 4 includes a guide seat 401, which is fixed to the inner side of the bottom shell 101. A guide plate 402 is slidably connected to the guide seat 401 and is connected to the end of the bladder 201. The guide assembly 4 also includes a U-shaped mounting plate 403, which is fixed to the guide plate 402 and is fixed to the bottom of the bladder 201.

[0036] The guide seat 401 is fixed to the inside of the bottom shell 101 by bolts. The guide plate 402 can slide up and down on the guide seat 401. The guide seat 401, the guide plate 402 and the U-shaped mounting plate 403 are used to limit the movement trajectory of the bladder 201 to ensure that it moves in the vertical direction in order to achieve intermittent support for the human body.

[0037] An electrorheological fluid pad 5 is mounted on the frame 1. The electrorheological fluid pad 5 includes a flexible wrapping material 501, within which an electrorheological fluid material 502 is disposed. The flexible wrapping material 501 is used to wrap the electrorheological fluid material 502, and an insulating material is disposed on the outside of the electrorheological fluid material 502. The flexible wrapping material 501 also needs to be made of insulating material. When the electrorheological fluid material 502 is energized, its viscosity can be controlled, and its softness and hardness can be adjusted to suit different patients and improve patient comfort.

[0038] In addition, when the electrorheological fluid material 502 switches to a rigid state, the electrorheological fluid pad 5 becomes rigid as a whole. At this time, the electrorheological fluid pad 5 can support the human body and has a strong load-bearing capacity. It can be used directly as a stretcher. Medical staff can lift the electrorheological fluid pad 5 to directly complete the non-contact horizontal displacement of the patient on the operating table, transfer bed, and hospital bed. This completely eliminates the risk of incision traction caused by traditional manual patient handling and the shearing damage caused by friction of mechanical devices. At the same time, it reduces the manpower required for bed transfer operations, significantly reduces the incidence of postoperative transfer-related complications, and improves the turnover efficiency of the ICU or operating room.

[0039] A control system includes the following steps: S1: The control system is activated. The pressure distribution on the bladder 201 is monitored by the pressure sensor 205. After the patient lies on the bladder 201, the pressure sensor 205 feeds back the captured pressure signal to the control system. The control system activates the vibration device 203 inside the bladder 201. The vibration device 203 drives the massage ball 204 on its top to vibrate, massaging the contact area between the human body and the bladder 201.

[0040] S2: The drive motor 301 is started at regular intervals by the control system. The working drive motor 301 drives the first eccentric block 303 and the second eccentric block 304 to rotate 180 degrees through the rotating shaft 302. The U-shaped mounting plate 403 on the first eccentric block 303, the bladder 201, and the U-shaped mounting plate 403 on the second eccentric block 304, as well as the bladder 201, will move up and down relative to each other, so that the bladder 201 provides intermittent support to the human body.

[0041] S3: When the human body leaves the capsule 201, the capsule 201 will reset. During the reset process, external air is drawn in through the one-way valve 202 on the other side, thereby forming a directional airflow circulation, accelerating the exchange of air between the inside of the bottom shell 101 and the outside air, and taking away the heat accumulated in the contact area between the capsule 201 and the human body.

[0042] S4: The electrorheological fluid material 502 is controlled by the control system to switch the electrorheological fluid material 502 to a hard state. In this state, the electrorheological fluid pad 5 can support the human body and can be used directly as a stretcher.

[0043] In use, the patient lies on the capsule 201, which supports the patient. When the capsule 201 is compressed and contracts, the air inside the capsule 201 is quickly discharged through the one-way valve 202 on one side. The start of the drive motor 301 can drive the rotating shaft 302 to rotate. The rotation of the rotating shaft 302 will cause the first eccentric block 303 and the second eccentric block 304 to rotate. Through the rotation of the first eccentric block 303 and the second eccentric block 304, the capsule 201 can provide intermittent support to the human body.

[0044] During intermittent support, the capsule 201 is in close contact with the human body. When the weight of the human body causes the capsule 201 to deform and squeeze the pressure sensor 205 at the bottom, the pressure sensor 205 captures the pressure signal in real time and feeds it back to the control system. The control system activates the vibration device 203 inside the capsule 201. The vibration device 203 drives the massage ball 204 at the top to vibrate and massage the pressure area. There is no need to manually adjust the massage position. The massage function is synchronized with the intermittent support and is triggered only when the human body is under pressure, avoiding interference from ineffective vibration.

[0045] During the intermittent support process, when the human body leaves the bladder 201, the bladder 201 will reset. During the reset process, external air is drawn in through the one-way valve 202 on the other side, thereby forming a directional airflow circulation, accelerating the exchange of air between the inside of the bottom shell 101 and the outside air, and removing the heat accumulated in the contact area between the bladder 201 and the human body. This avoids the stuffy and damp skin caused by prolonged bed rest. This heat dissipation method does not require additional power and is achieved naturally by intermittent mechanical movement, continuously keeping the contact area dry and relieving discomfort in the contact area.

[0046] The device's massage and heat dissipation functions work in tandem during intermittent support. The heat dissipation function lowers the temperature of the contact area, while the massage function relieves the discomfort caused by pressure on the contact area.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
