Detailed ways

In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments; in the drawings or descriptions, similar or identical parts use the same reference numerals, and in practical applications, the shape, thickness or height of each component can be enlarged or reduced. The various embodiments listed in the present invention are only used to illustrate the present invention and are not used to limit the scope of the present invention. Any obvious modifications or changes made to the present invention do not depart from the spirit and scope of the present invention.

Embodiment 1:

As shown in FIG. 1 to FIG. 5 , a massage and care foot cover for preventing pressure injuries of the foot provided by the present invention comprises:

The foot cover body 1 is a double-layer structure, and a plurality of air bags 2 are arranged in the hollow part, one side of the air bags 2 is fixed to the outer structure of the foot cover body 1, and the other side is freely arranged;

A massage control system configured to independently inflate and deflate the plurality of airbags 2 to enter a massage mode or to inflate all the airbags 2 to achieve a protection mode;

The side water bags 31 are arranged on two sides of the foot cover body 1 corresponding to the ankles of the human body;

The bottom water bag 32 is arranged at the bottom of the foot cover body 1 corresponding to the ankle of the human body; specifically, the side water bag 31 and the bottom water bag 32 are both arranged outside the foot cover body 1;

The anti-pressure control system is configured to fill or release water into the two side water bags 31 so as to make the foot cover body 1 tilt to one side or be placed in the center.

In this way, after the nursing foot cover of the present application is worn on the foot of a bedridden patient, the multiple air bags 2 are independently inflated and deflated through the massage control system, which can achieve the squeezing and massaging effect on the patient's foot and calf, promote the blood circulation of the legs of bedridden patients, and ensure the patient's certain physiological functions. In this process, the bottom water bag 32 and the two side water bags 31 can flexibly support the patient's ankle bone protrusions, which can effectively reduce the probability of pressure injuries on the ankle bone protrusions of patients who lie for a long time; and, with the help of the setting of the anti-pressure injury control system, the two side water bags 31 can also be controlled to alternately fill and discharge water, and the posture of the patient's feet can be automatically adjusted, which is suitable for automatic care of the patient's feet when there is no one to accompany or it is inconvenient to accompany at night.

In specific settings, the massage control system can be started manually, such as by timing or program; it can also be started automatically, for example, a number of blood oxygen saturation sensors are provided in the foot cover body 1, and the blood oxygen saturation sensors are connected to the massage control system; when the blood oxygen saturation sensor detects that the blood oxygen concentration has dropped to a preset value, the massage control system is controlled to start the massage mode. At this time, the blood oxygen saturation sensor provided in the foot cover body 1 can detect the blood oxygen concentration of the patient's feet in real time. When the blood flow in the patient's feet is not smooth, the blood oxygen concentration detected by the blood oxygen saturation sensor decreases, and the massage mode of the massage control system is started, which can timely perform air pressure massage on the patient's feet, which is especially suitable for patients who are in a coma and cannot express pain, and can greatly improve the user experience of this application.

Specifically, referring to FIG. 1 and FIG. 2 , the massage control system includes:

The bronchus 41 is provided in plurality and connected to the plurality of airbags 2 in a one-to-one correspondence;

The main airway 42 is provided in plurality and connected to the plurality of bronchi 41 , one main airway 42 corresponds to the plurality of bronchi 41 , and two adjacent bronchi 41 are connected to different main airways 42 ;

A first control valve 43 is provided on the main gas pipe 42;

An air pump 44 is connected to the plurality of main air pipes 42;

A first controller connected to the plurality of first control valves 43; and

A second controller connected to the air pump 44;

And when in the protection mode, the first controller controls the multiple first control valves 43 to open, and the second controller controls the air pump 44 to inflate. At this time, the multiple airbags 2 are inflated, and the patient's feet can be fully wrapped and shaped.

When in the massage mode, the second controller controls the air pump 44 to be opened and closed alternately, and the first controller controls the plurality of first control valves 43 to be opened and closed alternately.

Specifically, when the air pump 44 is turned on, the first group of first control valves 43 are closed, and the corresponding first group of airbags 2 are in a flattened state; the second group of first control valves 43 are opened, and the corresponding second group of airbags 2 are inflated, forming an air pressure massage effect on the second group of areas of the patient's feet; then the air pump 44 is closed, the second group of first control valves 43 remain open, and the gas in the second group of airbags 2 is released, and the second group of first control valves 43 are closed after a certain period of time. Subsequently, the air pump 44 continues to be turned on, the first group of first control valves 43 are opened, and the corresponding first group of airbags 2 are inflated, forming an air pressure massage effect on the first group of areas of the patient's feet. Such cyclic control can achieve an alternating air pressure massage effect on various parts of the patient's feet.

In addition, referring to FIG. 1 and FIG. 3 , the above-mentioned anti-pressure injury control system includes:

There are three water pipes 51, which are respectively connected to the bottom water bag 32 and the two side water bags 31;

A second control valve 52 is provided on the water pipe 51;

A water pump 53 connected to the three water pipes 51;

A third controller connected to the plurality of second control valves 52; and

A fourth controller connected to the water pump 53;

When the foot cover body 1 needs to be controlled to tilt to one side, the second control valve 52 corresponding to the side is controlled to open for a period of time and then closed; then the water pump 53 is controlled to open, and the second control valve 52 corresponding to the water bag 31 on the other side is controlled to open.

Specifically, when the patient's legs need to be tilted to the right, the second control valve 52 on the right is opened, the water in the side water bag 31 on the right is discharged and a certain amount is retained, and then the second control valve 52 is closed, the water pump 53 is controlled to be opened, the second control valve 52 on the left is opened, and the side water bag 31 on the left is filled with water. The expanded side water bag 31 can push the foot cover body 1 to drive the patient's feet to tilt to the right, thereby adjusting the posture of the patient's feet, and at the same time, it can always ensure the protection effect of the patient's ankle bone protrusion. In this process, the bottom water bag 32 can always maintain the flexible supporting effect of being filled with water, and can also be intermittent as needed to relieve the pressure on the bottom of the leg.

In order to realize the automatic start-up effect of the anti-pressure injury control system, blood oxygen saturation sensors are arranged on both sides of the foot cover body 1. When the blood oxygen saturation sensor on one side detects that the blood oxygen concentration on that side is reduced to a preset value, the anti-pressure injury control system is controlled to start to change the placement posture of the foot cover body 1.

In this way, for example, when the right blood oxygen saturation sensor detects that the blood oxygen concentration on that side of the patient's foot is reduced, it means that this side has been compressed for a long time. At this time, the second control valve 52 on the left is controlled to open, and the side bag on the left is released. Then the water pump 53 is started, and the side water bag 31 on the right is filled with water and expanded, which can lift up the right side of the patient's foot to release the pressure on the right side of the foot. In this way, it can be adaptively adjusted according to the patient's leg condition.

Furthermore, considering that after the patient wears the nursing foot cover of the present application for a long time, a lot of moisture and heat will accumulate in the legs, which will also cause pressure sores and cause skin ulcers.

To this end, referring to Figures 2, 4 and 5, a blowing tube 61 with its opening pointing into the foot cover body 1 is connected to the airbag 2, a valve structure is provided on the blowing tube 61, and a temperature detection component is provided on the foot cover body 1. When the temperature detection component detects that the temperature inside the foot cover body 1 is higher than a preset value, the valve structure is controlled to open.

Specifically, the valve structure includes:

A control tube 631, one end of which is closed and the other end of which is connected to the air blowing tube 61;

The connecting pipe 632 has one end connected to the airbag 2 and connected to the side wall of the connecting pipe 632;

A slider 633 is slidably disposed in the control tube 631;

The control spring 634 is disposed in the control tube 631, and one end of the control spring 634 is fixedly connected to the slider 633, and the other end of the control spring 634 is fixedly connected to one end of the control tube 631 close to the air blowing tube 61. In the initial state, the slider 633 is directly opposite to the connection part between the connecting tube 632 and the control tube 631;

The memory alloy spring 635 is disposed at the closed end of the control tube 631, and one end is fixedly connected to the slider 633, and the other end is connected to the closed end of the control tube 631, and it can stretch freely when the temperature is lower than the preset temperature, and return to the spring shape when the temperature is higher than the preset temperature;

The memory alloy spring 635 is used as a temperature detection element, and its stiffness coefficient in the spring form is greater than the stiffness coefficient of the control spring 634; when the slider 633 is facing the connection part between the connecting pipe 632 and the control pipe 631, the memory alloy spring 635 is in a stretched state when it restores the spring form.

Furthermore, a heat conducting sheet may be provided in the foot cover body 1, and the heat conducting sheet may be connected to the memory alloy spring 635, so as to ensure the temperature measurement sensitivity of the memory alloy spring 635 as much as possible.

In this way, when the temperature inside the foot cover body 1 is lower than the normal body temperature, the memory alloy spring 635 can be stretched arbitrarily, and the slider 633 moves to block the connection between the connecting pipe 632 and the control pipe 631 under the action of the control spring 634. At this time, the airbag 2 can be inflated and deflated under the control of the massage control system to perform air pressure massage operations. As the patient wears the foot cover body 1 for a long time, the temperature inside the foot cover body 1 rises. When the temperature inside the foot cover body 1 rises to exceed the normal body temperature, the memory alloy spring 635 returns to the spring shape and has elastic potential energy, which can pull the slider 633 to move away from the control spring 634. The control spring 634 is stretched. At this time, the connecting pipe 632 is connected to the control pipe 631, and the control pipe 631 is connected to the air blowing pipe 61. Therefore, the gas in the airbag 2 flows through the control pipe 631 and is blown out from the air blowing pipe 61, which can promote the flow of gas in the foot cover body 1 to bring out the heat and moisture in the foot cover body 1, and can effectively prevent the occurrence of pressure sores.

When the temperature inside the foot cover body 1 drops, the memory alloy spring 635 is in a freely stretchable state again. At this time, the elastic force of the control spring 634 pulls the slider 633 toward it to continue to block the connection between the connecting tube 632 and the control tube 631 to ensure that the massage control system can be restored to the massage mode.

Embodiment 2:

The difference between this embodiment and the first embodiment is that:

An air pressure sensor is also provided in the airbag 2. When the massage control system is not in the massage mode and the air pressure sensor detects that the airbag 2 loses pressure, the massage control system is controlled to replenish the pressure in the airbag 2, specifically, controlling the air pump 44 to inflate the airbag 2 until the set air pressure is reached.

In this way, when the airbag 2 loses pressure, it may be that the massage control system is in the massage mode, and the airbag 2 is deflated. At this time, there is no need to inflate the airbag 2 to replenish the pressure; if the massage control system is not in the massage mode, the airbag 2 loses pressure at this time, which means that the temperature inside the foot cover body 1 is too high, triggering the air blowing pipe 61 to blow air. In order to ensure the dehumidification and cooling effect of the air blowing pipe 61, the air pump 44 is controlled to inflate the airbag 2 at this time, which can ensure that the air blowing pipe 61 can continue to spray air until the temperature inside the foot cover body 1 drops, the slider 633 moves back to block the connecting pipe 632, and the air pressure in the airbag 2 rises to the set air pressure.

The specific working effects of the present invention are as follows:

When the whole device is in use, the nursing foot cover of the present application is worn on the foot of the bedridden patient, and the multiple air bags 2 are independently inflated and deflated through the massage control system, which can achieve the squeezing and massaging effect on the patient's feet and calves, promote the blood circulation of the legs of bedridden patients, and ensure the patient's certain physiological functions. In this process, the bottom water bag 32 and the two side water bags 31 can flexibly support the patient's ankle bone protrusions, which can effectively reduce the probability of pressure injuries on the ankle bone protrusions of patients who lie for a long time; and, with the help of the setting of the anti-pressure injury control system, the two side water bags 31 can also be controlled to alternately fill and discharge water, and the posture of the patient's feet can be automatically adjusted, which is suitable for automatic care of the patient's feet when there is no one to accompany or it is inconvenient to accompany at night.
