Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, specifically a combination pad for intelligent positioning support and pressure ulcer early warning for critically ill patients. Background Technology

[0002] In modern healthcare systems, nursing care in intensive care units (ICUs) is crucial, with patient safety being paramount. Critically ill patients often have severe conditions requiring prolonged bed rest and treatment, including intravenous fluids, oxygen therapy, and other medical interventions. During nursing care, ensuring patient comfort, regular turning, sputum expectoration, and airway clearance are key aspects of preventing various complications.

[0003] However, most critically ill patients suffer from severely impaired bodily functions and are unable to move independently. Maintaining the same bedridden position for extended periods can lead to numerous problems. On one hand, continuous pressure on local tissues obstructs blood circulation, easily causing muscle atrophy and significantly hindering the patient's recovery process. On the other hand, and more seriously, pressure injuries, commonly known as pressure sores, can develop insidiously. Clinical data shows that a significant proportion of critically ill patients who are bedridden for extended periods suffer from pressure sores. Once pressure sores develop, they not only increase patient suffering and prolong hospital stays but can also lead to serious complications such as infections, and even threaten the patient's life.

[0004] Although some pressure ulcer prevention devices and nursing mattresses exist on the market, many shortcomings remain. Some products only provide simple turning assistance, lacking intelligent support for patient positioning and failing to accurately adapt to different patients' physical conditions and treatment needs. Others, while offering massage functions, are ineffective and fail to effectively promote blood circulation. Furthermore, existing pressure ulcer prevention products generally lack effective pressure ulcer warning mechanisms, failing to detect potential pressure ulcer risks in a timely manner, thus hindering caregivers from taking immediate intervention measures.

[0005] To effectively address these issues, meet the nursing needs of critically ill patients, and improve the quality of care, we have developed a smart postural support and pressure ulcer warning combination pad for critically ill patients. This combination pad aims to provide comprehensive postural support and pressure ulcer prevention protection for critically ill patients through innovative design and advanced technology. Simultaneously, it utilizes an intelligent warning system to help nursing staff promptly identify and manage pressure ulcer risks, thus safeguarding the recovery of critically ill patients. Utility Model Content

[0006] In view of the shortcomings of the existing technology, a combination pad for intelligent positioning support and pressure ulcer warning for critically ill patients is provided. It can easily observe the location of pressure ulcers in critically ill patients, locate the pressure ulcers in a timely manner, and adjust the patient's lying position to alleviate pressure ulcer problems.

[0007] To achieve the above and other related objectives, this utility model proposes a combination pad for intelligent postural support and pressure ulcer early warning in critically ill patients, comprising:

[0008] Support pad;

[0009] An airbag assembly is mounted on the support pad. The airbag assembly is connected to the air inlet and air outlet of an air supply device via a pipeline. The air supply device is capable of supplying or venting air to a portion of the airbag assembly.

[0010] Install a soft pad on the airbag assembly;

[0011] A temperature-sensing pad is laid on the mounting pad;

[0012] A temperature sensing element is arranged in an array on the temperature sensing pad and is used to acquire the temperature of each area on the temperature sensing pad.

[0013] The control unit acquires the temperature of the temperature sensing element and controls the air supply device to supply or vent air to a portion of the airbag assembly in order to adjust the patient's posture.

[0014] In one embodiment of the present invention, the airbag assembly includes multiple sets of unit airbags, which are arranged in an array on the support pad, and the multiple sets of unit airbags are respectively connected to the air inlet and exhaust outlet of the air supply device through pipelines.

[0015] In one embodiment of the present invention, the unit airbag is in the form of a cuboid, and the unit airbag is composed of at least three airbags connected in series. An air inlet pipe and an air outlet pipe are respectively provided on both sides of the unit airbag.

[0016] In one embodiment of this utility model, the support pad is made of flexible silicone, and a receiving groove is formed on the support pad. Multiple sets of receiving grooves are arranged parallel to each other along the width and length directions of the support pad, and the tubing of the unit airbag is located in the receiving groove.

[0017] In one embodiment of this utility model, a rigid support plate is provided on the support pad, and multiple sets of the rigid support plate are arranged parallel to each other along the length direction of the support pad, with the multiple sets of unit airbags abutting against the rigid support plate.

[0018] In one embodiment of this utility model, the mounting pad is made of highly elastic sponge, and grooves are formed on both sides of the mounting pad. Multiple sets of grooves are arranged parallel to each other along the width and length directions of the mounting pad, and the intersecting grooves divide the two sides of the mounting pad into a grid surface.

[0019] In one embodiment of this utility model, the mounting pad and the temperature sensing pad are connected by Velcro, and multiple sets of Velcro are arranged at intervals between the mounting pad and the temperature sensing pad.

[0020] In one embodiment of the present invention, a connecting pin is provided between the support pad and the mounting pad, and the connecting pin is arranged at the four corners of the support pad and the mounting pad.

[0021] In one embodiment of the present invention, insertion tubes are provided at the four corners of the support pad. The insertion tubes are plastic tubes with deformation openings on the outer wall. Insertion pins are provided at the four corners of the mounting pad. One end of the insertion pin is spherical and inserted into the cavity of the insertion tube.

[0022] In one embodiment of this utility model, stepped holes are provided at the four corners of the mounting pad, and the plug pin is T-shaped in general. The smaller end of the plug pin passes through the stepped hole and is plugged into the plug tube.

[0023] By adopting the above technical solution, the technical effect of this utility model is as follows: the temperature sensing pad and temperature sensing element monitor the temperature of various parts of the patient's body in real time. Once an abnormal increase in local temperature is detected, it indicates that the area may have poor blood circulation due to prolonged pressure, and there is a risk of pressure sores. At this time, the control unit responds quickly, accurately judges the pressure area based on the temperature data, and then controls the air supply device to supply or vent air to the corresponding part of the airbag assembly, adjusts the patient's position in time, reduces local pressure, effectively prevents the occurrence of pressure sores, and reduces patient pain and medical costs.

[0024] The airbag assembly works in conjunction with the air supply device. According to the instructions of the control unit, it can supply or vent air to different areas of the airbag assembly in a targeted manner. This allows the support pad to flexibly adjust its shape and support strength according to the patient's physical condition and treatment needs, providing precise positional support for the patient. Whether it is helping the patient turn over, lie on their side, or adjust to a specific treatment position, it can be easily achieved, improving the patient's comfort and promoting the treatment effect.

[0025] The temperature sensors are arrayed on the temperature pad, which can comprehensively acquire temperature information from all areas of the temperature pad. This temperature data is transmitted to the control unit in real time. Medical staff can intuitively view the temperature changes of various parts of the patient's body through relevant equipment, realize real-time monitoring of the patient's physical condition, and take timely measures in case of any abnormality, providing more reliable protection for the patient's life and health.

[0026] The entire system operates intelligently, eliminating the need for medical staff to frequently adjust the patient's position manually. The control unit automatically analyzes the data collected by the temperature sensor and controls the gas supply equipment to perform corresponding actions, greatly reducing the workload of medical staff and improving nursing efficiency and quality. At the same time, the intelligent nursing mode also reduces the risk of pressure ulcers caused by untimely or inaccurate manual operation, providing more scientific and humane nursing services for critically ill patients.

[0037] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0038] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0039] Most critically ill patients currently suffer from severely impaired bodily functions and are unable to move independently. Maintaining the same bedridden position for extended periods can lead to numerous problems. On one hand, continuous pressure on local tissues obstructs blood circulation, easily causing muscle atrophy and significantly hindering the patient's recovery process. On the other hand, and more seriously, pressure injuries, commonly known as pressure sores, can develop insidiously. Clinical data shows that a significant proportion of critically ill patients who are bedridden for extended periods suffer from pressure sores. Pressure ulcers not only increase patient suffering and prolong hospital stays, but can also lead to serious complications such as infection, and even threaten the patient's life. To address this, a smart positioning support and pressure ulcer warning combination pad for critically ill patients is proposed, comprising: a support pad 10; an airbag assembly 20 disposed on the support pad 10, the airbag assembly 20 being connected to the air inlet and outlet of an air supply device via tubing, the air supply device being able to supply or vent air to a portion of the airbag assembly 20; a mounting pad 30 disposed on the airbag assembly 20; a temperature-sensing pad 40 laid on the mounting pad 30; temperature sensors 50 arranged in an array on the temperature-sensing pad 40 for acquiring the temperature of various areas on the temperature-sensing pad 40; and a control unit acquiring the temperature of the temperature sensors 50 and controlling the air supply device to supply or vent air to a portion of the airbag assembly 20 to adjust the patient's posture.

[0040] In one embodiment, see Figures 1 to 10The support pad 10 is made of a relatively hard material. As the support frame of the entire mattress, it should not be too hard and is preferably soft silicone. The airbag assembly 20 is provided with multiple independent inflation zones. The air supply device can be controlled by the control unit to supply or deflate air to some areas of the airbag assembly 20 to adjust the patient's posture, thereby avoiding pressure sores caused by prolonged contact between the patient's body and the mattress.

[0041] In one embodiment, when the patient is in a supine position, the arrangement area of ​​the airbag assembly 20 can be set according to the position of the sacrum, coccyx, occiput, elbow, and heel of the critically ill patient. When the patient is in a prone position, the arrangement area of ​​the airbag assembly 20 can be set according to the position of the subclavian, forehead, mandible, bilateral acromion, anterior superior iliac spine, knee, and toes of the critically ill patient.

[0042] In one embodiment, see Figure 4 and Figure 5 The installed pad 30 can move up and down with the inflation or deflation of certain areas to adjust the posture of critically ill patients and prevent the patient's body from being in contact with the mattress for a long time.

[0043] In one embodiment, see Figure 1 The temperature-sensing pad 40 is a pad made of commercially available temperature-sensing film. When a patient lies on the temperature-sensing pad 40 for a long time, the area in contact with the temperature-sensing pad 40 will change color. Nursing staff can adjust the patient's posture in a timely manner. They can also adjust the patient's posture by controlling the airbag assembly 20 through the control unit based on the temperature collected by the temperature-sensing component 50.

[0044] In one embodiment, see Figure 1 The temperature sensing element 50 is a patch-type temperature sensor. Multiple sets of temperature sensing elements 50 are embedded on the temperature sensing pad 40, which can collect the temperature of multiple locations on the temperature sensing pad 40.

[0045] In one embodiment, see Figure 6 and Figure 7 In order to achieve precise control of air release or deflation in multiple areas of the airbag assembly 20, the airbag assembly 20 includes multiple sets of unit airbags 21, which are arranged in an array on the support pad 10, and the multiple sets of unit airbags 21 are respectively connected to the air inlet and air outlet of the air supply device through pipelines.

[0046] In one embodiment, see Figure 6 and Figure 7 The unit airbag 21 has a rectangular parallelepiped structure and is composed of at least three airbags connected in series. An air inlet pipe 211 and an air outlet pipe 212 are respectively provided on both sides of the unit airbag 21.

[0047] In one embodiment, the multiple sets of unit airbags 21 cooperate with each other to adjust the lying posture of critically ill patients, so as to separate the area of ​​the critically ill patient in contact with the mattress for a long time from the mattress.

[0048] In one embodiment, see Figure 9 To facilitate the accommodation of the pipeline, the support pad 10 is made of flexible silicone, and a receiving groove 11 is provided on the support pad 10. Multiple sets of receiving grooves 11 are arranged parallel to each other along the width and length directions of the support pad 10, and the pipeline of the unit airbag 21 is located in the receiving groove 11.

[0049] In one embodiment, to support the unit airbag 21, a rigid support plate 60 is provided on the support pad 10. Multiple sets of rigid support plates 60 are arranged parallel to each other along the length direction of the support pad 10, and multiple sets of unit airbags 21 are attached to the rigid support plate 60.

[0050] In one embodiment, the rigid support plate 60 is made of polymer plastic material, and when the unit airbag 21 abuts against the rigid support plate 60, it can drive the mounting pad 30 to deform.

[0051] In one embodiment, the mounting pad 30 is made of highly elastic sponge, and grooves 31 are formed on both sides of the mounting pad 30. Multiple sets of grooves 31 are arranged parallel to each other along the width and length directions of the mounting pad 30. The intersecting grooves 31 divide the two sides of the mounting pad 30 into a grid surface.

[0052] In one embodiment, see Figure 1 and Figure 4 To facilitate the connection between the mounting pad 30 and the temperature sensing pad 40 and to make disassembly convenient, the mounting pad 30 and the temperature sensing pad 40 are connected by Velcro 70, and multiple sets of Velcro 70 are arranged at intervals between the mounting pad 30 and the temperature sensing pad 40.

[0053] In one embodiment, in order to achieve a fixed connection between the support pad 10 and the mounting pad 30, a connecting pin 32 is provided between the support pad 10 and the mounting pad 30, and the connecting pin 32 is arranged at the four corners of the support pad 10 and the mounting pad 30.

[0054] Specifically, see Figure 5 and Figure 10The support pad 10 is provided with insertion tubes 12 at its four corners. The insertion tubes 12 are plastic tubes with deformation openings 121 on their outer walls. Insertion pins 32 are provided at the four corners of the mounting pad 30. One end of the insertion pin 32 is spherical and is inserted into the cavity of the insertion tube 12. When the insertion pin 32 is inserted into the cavity of the insertion tube 12, the insertion tube 12 opens at the deformation opening 121, and the tube wall of the insertion tube 12 clamps the ball end of the insertion pin 32, thus achieving a reliable connection between the support pad 10 and the mounting pad 30.

[0055] More specifically, see Figure 10 The mounting pad 30 has stepped holes 33 at its four corners. The insertion pin 32 is T-shaped. The smaller end of the insertion pin 32 passes through the stepped holes 33 and is inserted into the insertion tube 12.

[0056] In summary, by using the temperature-sensing pad 40 and temperature-sensing element 50 to monitor the temperature of various parts of the patient's body in real time, if an abnormally high local temperature is detected, it indicates that the area may be experiencing poor blood circulation due to prolonged pressure, posing a risk of pressure sores. At this time, the control unit responds quickly, accurately determining the pressure area based on the temperature data, and then controlling the air supply device to supply or deflate the corresponding part of the airbag assembly 20, adjusting the patient's position in a timely manner, reducing local pressure, effectively preventing the occurrence of pressure sores, and reducing patient suffering and medical costs. The airbag assembly 20 and the air supply device work together, and according to the instructions of the control unit, can provide targeted air supply or deflation to different areas of the airbag assembly 20. This allows the support pad 10 to flexibly adjust its shape and support strength according to the patient's physical condition and treatment needs, providing precise positional support for the patient. Whether helping the patient turn over, lie on their side, or adjust to a specific treatment position, it can be done easily. This system improves patient comfort and enhances treatment effectiveness. Temperature sensors 50 are arrayed on the temperature-sensing pad 40, comprehensively acquiring temperature information from all areas of the pad. This temperature data is transmitted to the control unit in real time, allowing medical staff to visually monitor temperature changes in various parts of the patient's body. This enables real-time monitoring of the patient's condition, allowing for timely intervention in case of abnormalities and providing more reliable protection for the patient's health. The entire system operates intelligently, eliminating the need for frequent manual adjustments to the patient's position. The control unit automatically analyzes the data collected by the temperature sensors and controls the air supply equipment accordingly, significantly reducing the workload of medical staff and improving nursing efficiency and quality. Furthermore, this intelligent nursing model reduces the risk of pressure ulcers caused by untimely or inaccurate manual operations, providing more scientific and humane nursing services for critically ill patients.
