Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a skin care pad. Background Art

[0002] Clinically, patients are in a sitting position for a long time. In this case, the risk of pressure sores on the buttocks of patients is relatively high. For postpartum or postoperative patients, pressure sores may also easily lead to the deterioration of existing skin inflammation. Therefore, a seat cushion for such patients is needed. Currently, existing seat cushions have the following problems:

[0003] 1. Currently, most commonly used seat cushions are integrated and do not have the function of regional pressure adjustment. They cannot achieve dynamic pressure adjustment well and still have the risk of pressure sores under long-term contact.

[0004] 2. The ventilation and air permeability function of existing seat cushions is mostly achieved by the loose structure or material of the seat cushions themselves, and the direction and strength of ventilation and air permeability cannot be controlled. When the seat cushions have temperature regulation or constant temperature functions, low-permeability seat cushions are particularly prone to causing new dermatitis in patients.

[0005] Therefore, there is a need for a nursing cushion that can control the pressure on the part in contact with the patient and can ensure ventilation effect under the premise of constant temperature, specifically a skin care cushion. Summary of the invention

[0006] In order to overcome the problems raised in the background technology, the present invention adopts the following technical solutions:

[0007] A skin care pad comprises a decompression module, a containing module, a breathable component and a temperature control component; the decompression module can change the pressure at the contact position with the patient, comprises a decompression unit that directly contacts the patient, and a first control component that controls the pressure between the decompression unit and the patient, and the decompression unit is connected to the first control component; the containing module is used to provide a placement space for the decompression module, comprises a pad body that directly contacts the patient and a placement cavity that accommodates the decompression module, the placement cavity is arranged inside the pad body and communicates with the outside world through the top of the pad body; the breathable component is used to increase the air flow rate at the contact point between the patient and the care pad, thereby facilitating the recovery of dermatitis and avoiding the generation of new skin inflammation, by arranging the breathable component and cooperating with the gap between the decompression unit and the containing module, the air flow moves smoothly on the surface of the care pad, and the breathable component is arranged on the containing module; the temperature control component is used to keep the care pad in a constant temperature state when it contacts the patient, and the temperature control component is arranged inside the containing module.

[0008] Furthermore, the decompression unit is arranged inside the placement cavity, and the decompression unit includes an initial state and a decompression state. When in the initial state, the top of the decompression unit protrudes from the placement cavity and is higher than the top of the cushion body; when in the decompression state, the decompression unit retracts into the placement cavity so that the pressure on the corresponding part of the patient decreases.

[0009] Furthermore, the first control component includes a timing control structure, which defines a control interval as a minute and a control duration as b minutes. When a decompression unit is in contact with the patient for a period of time in an initial state, the timing control structure controls the decompression unit to be converted to a decompression state and converts the decompression unit back to the initial state after b minutes.

[0010] Furthermore, the regulation interval and regulation duration of each decompression unit are the same, but the timing start time points of different decompression units are different, so that different decompression units will not simultaneously undergo conversion between two states.

[0011] Furthermore, each of the placement cavities is composed of at least one cavity unit, the placement cavities are not connected to each other, and the cushion body is vertically provided with vertical holes at positions between different placement cavities. By arranging the vertical holes around the placement cavities, the cushion body has better air permeability, and the vertical holes are not connected to the placement cavities.

[0012] Furthermore, a vertical through hole is provided in the center of the cushion body, which is used to keep the center of the buttocks suspended and enhance the ventilation effect, and the breathable component is connected to the through hole.

[0013] Furthermore, the breathable component includes an air supply structure for guiding the airflow direction in one direction and a second control component. The air supply structure and the second control component are connected by a wire. The second control component is used to change the airflow direction of the air supply structure. When the air supply structure guides the airflow toward the top of the cushion body, the breathable component is in a heat dissipation state; when the air supply structure guides the airflow toward the bottom of the cushion body, the breathable component is in a breathable state.

[0014] Furthermore, the temperature control component includes a constant temperature structure, and the constant temperature structure is arranged on one side of the interior of the pad body close to the top.

[0015] Furthermore, the temperature control component also includes a third control component for automatically and / or manually controlling the temperature of the constant temperature structure, and the third control component is connected to the constant temperature structure via a wire.

[0016] Furthermore, when the cushion body is placed on a platform parallel to a horizontal plane, the cross-sectional shape of the cushion body along the vertical direction is annular.

[0017] Beneficial effects of the present invention:

[0018] 1. By setting a controllable decompression unit, when multiple decompression units are in the initial state, a certain decompression unit is put in the decompression state, so that the pressure between the decompression unit in the decompression state and its corresponding patient part is reduced, and after the decompression unit returns to the initial state, the states of other decompression units are changed in turn, thereby achieving dynamic regulation of the patient contact surface pressure, which has a good effect in preventing pressure sores.

[0019] 2. By setting up ventilation components and coordinating the gaps between the decompression units and the vertical holes on the pad body, the nursing pad has good ventilation effect, controllable ventilation direction and multiple ventilation paths.

[0020] 3. By setting up a constant temperature component and cooperating with a ventilation component, the patient's skin is kept in a constant temperature and relatively dry state, thereby effectively inhibiting the spread of dermatitis. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below through specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation methods. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] A skin care pad, reference Figure 1-7 , including a decompression module 1, a receiving module 2, a breathable component 3 and a temperature control component 4; the decompression module 1 can change the pressure at the contact position with the patient, including a decompression unit 11 that directly contacts the patient, and a first control component 12 that controls the pressure between the decompression unit 11 and the patient, and the decompression unit 11 is connected to the first control component 12; the receiving module 2 is used to provide a placement space for the decompression module 1, including a pad body 21 that directly contacts the patient and a placement cavity 22 that accommodates the decompression module 1, and the placement cavity 22 is arranged inside the pad body 21 and communicates with the outside world through the top of the pad body 21; the breathable component 3 is used to increase the air flow rate at the contact part between the patient and the nursing pad so as to keep the skin dry and accelerate the recovery of dermatitis. By setting the breathable component 3 and cooperating with the gap between the decompression unit 11 and the receiving module 2, the air flow moves smoothly on the surface of the nursing pad, and the breathable component 3 is arranged on the receiving module 2; the temperature control component 4 is used to keep the nursing pad in a constant temperature state when it contacts the patient, and the temperature control component 4 is arranged inside the receiving module 2.

[0032] A more preferred embodiment is to refer to Figure 1-7The decompression unit 11 is arranged inside the placement cavity 22. The decompression unit 11 includes an initial state and a decompression state. When in the initial state, the top of the decompression unit 11 protrudes from the placement cavity 22 and is higher than the top of the cushion body 21. When in the decompression state, the decompression unit 11 retracts into the placement cavity 22 so that the pressure on the corresponding part of the patient decreases. The decompression unit 11 is specifically an air bag with an inflation pipeline 111, and the air bag is placed in the placement cavity 22. The inflation pipeline 111 passes through the cushion body 21 and is exposed to the outside of the cushion body 21. The first control component 12 is connected to the inflation pipelines 111 of all the decompression units 11 on the outside of the cushion body 21. An inflation device is arranged on the outside of the cushion body 21. The inflation device is connected to the first control component 12 by setting an external pipeline. A one-way valve or a one-way flap is provided on the external pipeline to prevent the gas in the inflation device from being directly output. Each inflation pipeline 111 can be inserted into or withdrawn from the external pipeline under the control of the first control component 12. The first control component 12 includes a plurality of claws connected to a timer. The claws can slide back and forth along the axial direction when the inflation pipeline 111 is inserted into the first control component 12. When the inflation pipeline 111 is inserted into the first control component 12, it will be sleeved by the claw, and then can be inserted into the external pipeline according to the defined control interval, and can be withdrawn from the external pipeline after the control time ends, finally realizing the switching between the initial state and the decompression state.

[0033] In this embodiment, the decompression units 11 are distributed on the cushion body 21 in a circular array around the through hole 212. The first control component 12 includes a single-chip microcomputer that can write and control the on-off relationship between the external pipeline and the inflation pipeline 111, as well as a replaceable battery. These are all existing technologies. Under the action of the first control component 12, each decompression unit 11 in the circular array can shrink and expand in turn, providing uniform and appropriate decompression and relaxation to different contact parts of the patient, thereby achieving a good preventive effect on dermatitis and pressure sores.

[0034] Another more preferred implementation is that the decompression unit 11 is an elastic block, the specific material of the elastic block is silicone or medical rubber or latex, and a telescopic structure that can be vertically lifted and lowered is connected to the lower end of the elastic block. When the first control component 12 is connected to the telescopic structure, the elastic block can be controlled to squeeze the patient upward or move downward away from the patient. When all the elastic blocks move up and down according to the set rules, the contact parts of the patient and the nursing pad can be relaxed in turn, thereby preventing the occurrence of pressure sores and dermatitis.

[0035] A more preferred embodiment is to refer to Figure 1-7The first control component 12 includes a timing control structure 121, that is, various existing technologies for calculating time and controlling the on-off of the circuit and claws connected to such existing technologies, which can be specifically a reset claw connected to the timer. When the first timing is over, the connection between the external pipeline and the inflation pipeline 111 is disconnected, and when the second timing is over, the connection between the external pipeline and the inflation pipeline 111 is restored, and then the next cycle is entered. The control interval is defined as a minute and the control duration is b minutes. When a decompression unit 11 is in contact with the patient in the initial state for a, the timing control structure 121 controls the decompression unit 11 to be converted to the decompression state and converts the decompression unit 11 back to the initial state after b minutes, where 20min<a<120min, 5min<b<10min. The control interval and control duration of each decompression unit 11 are the same, but the time points for starting timing between different decompression units 11 are different, so that different decompression units 11 will not simultaneously undergo conversion between two states.

[0036] A more preferred embodiment is to refer to Figure 1-7 Each placement cavity 22 is composed of at least one cavity unit. The placement cavities 22 are not connected. The cushion body 21 is vertically penetrated with vertical holes 211 at positions between different placement cavities 22. The cushion body 21 has better air permeability by arranging the vertical holes 211 around the placement cavities 22. The vertical holes 211 are not connected to the placement cavities 22. The cushion body 21 is made of high-strength gel or medical plastic wrapped with an elastic layer, which can ensure that patients of different weights will not bend the vertical holes 211 and through holes 212 to a blocked state when sitting down. The arrangement of the vertical holes 211 can also enhance the longitudinal pressure resistance of the cushion body 21 to a certain extent, thereby avoiding the occurrence of ventilation obstruction. The elastic layer is tpe, foam or latex, which brings a smoother contact experience to the patient.

[0037] A more preferred embodiment is to refer to Figure 1-7The center of the cushion body 21 is provided with a vertical through hole 212, which is used to keep the center of the buttocks suspended and enhance the ventilation effect. The ventilation component 3 is connected to the through hole 212. The ventilation component 3 includes an air supply structure 31 and a second control component 32 for guiding the airflow direction in one direction. The air supply structure 31 and the second control component 32 are connected by a wire. The second control component 32 is used to change the airflow direction of the air supply structure 31. When the air supply structure 31 guides the airflow to the top of the cushion body 21, the ventilation component 3 is in a heat dissipation state; when the air supply structure 31 guides the airflow to the bottom of the cushion body 21, the ventilation component 3 is in a ventilation state. The air supply structure 31 can be one or more groups of vertically stacked rotor fans. The second control component 32 is a direction-changing switch and an energy supply structure embedded in the rotor fan. The energy supply structure can be a rechargeable battery or a micro battery. Because the air supply structure 31 needs to run continuously during use, the ventilation direction can be selected before each use. The above structure can achieve this function.

[0038] Another more preferred embodiment is that the second control component 32 is also a control module connected to the air supply structure 31, but the ventilation direction of the air supply structure 31 can be controlled from the outside through wired or wireless control when the patient uses it, which has a more flexible operation method.

[0039] A more preferred embodiment is to refer to Figure 1-7 The temperature control component 4 includes a constant temperature structure 41, which is arranged on one side of the inner part of the pad body 21 near the top. The temperature control component 4 also includes a third control component 42, which is used to automatically and / or manually control the temperature of the constant temperature structure 41, and the third control component 42 is connected to the constant temperature structure 41 through a wire. The constant temperature structure 41 is an electric heating wire or electric heating plate, and the outside of the constant temperature structure 41 is wrapped with an insulating heat-conducting structure, and the top area of ​​the pad body 21 corresponding to the constant temperature structure 41 is no longer provided with an elastic layer, but is provided with a woolen fabric or a fabric with velvet on the surface, so as to achieve a certain heat preservation effect and relatively concentrate the temperature at the wound position close to the center of the patient's buttocks.

[0040] A more preferred embodiment is to refer to Figure 1-7 When the cushion body 21 is placed on a platform parallel to the horizontal plane, the cross-sectional shape of the cushion body 21 along the vertical direction is annular, and the outermost contour of the cushion body 21 is closer to an ellipse, which can better adapt to the contour of the patient's buttocks in a sitting position.

[0041] Example 2

By setting the breathable component 3 and cooperating with the gap between the decompression unit 11 and the receiving module 2, the air flow moves smoothly on the surface of the nursing pad, and the breathable component 3 is arranged on the receiving module 2; the temperature control component 4 is used to keep the nursing pad in a constant temperature state when it contacts the patient, and the temperature control component 4 is arranged inside the receiving module 2.

These decompression units 11 and placement cavities 22 are radially diffused outward with the center of the through hole 212 as the reference point. The principle of the first control component 12 in this embodiment is the same as the first control component 12 in embodiment 1, except that the different decompression units 11 in this embodiment can slightly push the patient's skin at the corresponding position around during the expansion process, and can reduce the pressure on the patient's contact parts during the contraction process, thereby preventing the patient from developing pressure sores and dermatitis while having a better rehabilitation auxiliary effect.

[0044] A more preferred embodiment is to refer to Figure 1-7 The first control component 12 includes a timing control structure 121, that is, various existing technologies for calculating time and controlling the on-off of the circuit and claws connected to such existing technologies, which can be specifically a reset claw connected to the timer. When the first timing is over, the connection between the external pipeline and the inflation pipeline 111 is disconnected, and when the second timing is over, the connection between the external pipeline and the inflation pipeline 111 is restored, and then the next cycle is entered. The control interval is defined as a minute and the control duration is b minutes. When a decompression unit 11 is in contact with the patient in the initial state for a, the timing control structure 121 controls the decompression unit 11 to be converted to the decompression state and converts the decompression unit 11 back to the initial state after b minutes, where 20min<a<120min, 5min<b<10min. The control interval and control duration of each decompression unit 11 are the same, but the time points for starting timing between different decompression units 11 are different, so that different decompression units 11 will not simultaneously undergo conversion between two states.

The cushion body 21 is made of high-strength gel or medical plastic wrapped with an elastic layer, which can ensure that patients of different weights will not bend the vertical holes 211 and through holes 212 to a blocked state when sitting down. The arrangement of the vertical holes 211 can also enhance the longitudinal pressure resistance of the cushion body 21 to a certain extent, thereby avoiding the occurrence of ventilation obstruction. The elastic layer is tpe, foam or latex, which brings a smoother contact experience to the patient.

The air supply structure 31 and the second control component 32 are connected by a wire. The second control component 32 is used to change the airflow direction of the air supply structure 31. When the air supply structure 31 guides the airflow to the top of the cushion body 21, the ventilation component 3 is in a heat dissipation state; when the air supply structure 31 guides the airflow to the bottom of the cushion body 21, the ventilation component 3 is in a ventilation state.
