Description

Technical Field

[0001] This invention belongs to the field of nursing devices, and specifically relates to a postoperative nursing device for dowager's hump and its control method. Background Technology

[0002] The procedure for treating a "dowager's hump" is a liposuction or fat removal procedure at the back of the neck. Currently, the mainstream post-operative care for dowager's hump generally uses either a "cotton pad with elastic bandage" or a "one-piece elastic garment". The "cotton pad with elastic bandage" method involves the doctor placing a cotton pad in the surgical area (the junction of the neck and back) and then tightening it with an elastic bandage. The elasticity of the bandage compresses the skin flap to prevent subcutaneous fluid accumulation and hematoma, and promotes healing. The "one-piece elastic garment" is used in a similar way.

[0003] However, the aforementioned devices have the following significant drawbacks: Constant pressure, unable to adapt to changes in body position. The pressure of the elastic bandage is fixed; when the patient stands / walks, gravity causes the skin flap to sag, often resulting in insufficient bandage pressure, unstable fixation, and easy fluid accumulation. When the patient lies flat, their entire body weight presses on the back wound, compounded by the pressure of the elastic bandage or elastic garment, leading to extremely high local pressure (often exceeding the 32 mmHg capillary occlusion threshold), easily causing skin ischemia and necrosis or pressure sores; lack of physical protection, existing bandages are soft and cannot provide cushioning space for the wound when lying flat, resulting in intense pain for the patient; poor breathability, prone to infection, the tight elastic bandage causes the affected area to be hot and moist, preventing sweat from escaping and increasing the risk of wound infection, and the device cannot actively ventilate; lack of quantitative standards, the applied pressure is entirely based on the doctor's feel, lacking digital monitoring methods, posing a risk of over- or under-pressure. Summary of the Invention

[0004] To overcome the shortcomings and problems of existing technologies, this invention provides a postoperative care device and control method for dowager's hump, which can automatically adjust the pressure when the patient's body position changes and causes pressure changes, thereby promoting the patient's recovery.

[0005] This invention is achieved through the following technical solution:

[0006] A postoperative care device for dowager's hump includes a care panel, an air supply drive system, and a controller. The care panel is connected to a strap and includes a rigid outer shell and a skin-friendly breathable layer that fit together. The rigid outer shell has a recessed cavity adapted to the surgical area of ​​the dowager's hump. Corresponding to the recessed cavity, an airbag is exposed on the skin-friendly breathable layer. The side of the airbag facing the surgical area of ​​the dowager's hump is provided with a waterproof and breathable isolation membrane. The airbag contains multiple independent airbags. Each independent airbag is provided with a pressure sensor between itself and the rigid outer shell. Each independent airbag is connected to the air supply system. The pressure sensors and the air supply system are electrically connected to the controller.

[0007] The multiple independent airbags within the airbag cushion consist of a central airbag and multiple peripheral airbags. The central airbag is positioned at the center of the recessed receiving cavity, and the multiple peripheral airbags are arranged around the central airbag, with each peripheral airbag being equidistant.

[0008] The air supply drive system includes an air pump, and each air pump is connected to an air supply pipe. Each air supply pipe is equipped with an air supply control solenoid valve that is electrically connected to the controller.

[0009] The inner surface of the rigid shell is provided with a reciprocating, serpentine tube groove. A vent pipe is arranged in the tube groove, and multiple air inlets are arranged on the vent pipe. The vent pipe is connected to an air pump via an air blowing solenoid valve, and the air blowing solenoid valve is electrically connected to the controller.

[0010] The airbag is equipped with a temperature sensor and a humidity sensor.

[0011] The rigid outer shell is made of ABS or carbon fiber, and the waterproof and breathable isolation membrane is made of expanded polytetrafluoroethylene.

[0012] The end of the strap is fixed to the nursing plate. The strap is flat and wide, and a quick-release buckle assembly is provided in the middle of the strap.

[0013] This invention is also achieved through the following technical solutions:

[0014] A method for controlling a postoperative care device for dowager's hump includes:

[0015] Step S01: Preset multiple modes according to the postoperative time, and preset the pressure of each independent airbag according to the mode. The preset pressure of the central airbag is 4 mmHg lower than that of the peripheral airbags.

[0016] Step S02: The pressure sensor feeds back the real-time pressure of each independent airbag to the controller, and the controller adjusts the pressure of each independent airbag to the preset pressure range according to the mode.

[0017] There are three preset modes in step S01: an acute phase mode for 0-2 days post-surgery, a subacute phase mode for 3-7 days post-surgery, and a remodeling phase mode for 7 days post-surgery. The preset pressure of the periphery airbag in the acute phase mode is 22-26 mmHg, the preset pressure of the periphery airbag in the subacute phase mode is 18-22 mmHg, and the preset pressure of the periphery airbag in the remodeling phase mode is 15-18 mmHg.

[0018] The control method of the postoperative care device for dowager's hump also includes step S03, in which the temperature sensor and humidity sensor respectively feed back the temperature and humidity information to the controller. For example, if the relative humidity is ≥70% or the skin temperature is ≥36.5℃, the controller controls the air blowing solenoid valve to open the ventilation tube for blowing. When the relative humidity is ≤60%, the controller controls the air blowing solenoid valve to close.

[0019] This invention features a rigid outer shell and airbag cushions. The independent airbags within the cushions can independently adjust their pressure. The rigid outer shell provides rigid support, withstanding body weight when the patient is lying down, thus completely eliminating the risk of pressure sores. As the patient's position changes, altering the gap between the airbag cushions and the surgical area, each independent airbag automatically adjusts its pressure, maintaining a constant pressure within a range conducive to recovery. The dynamic pressure application by the independent airbags ensures a shaping effect, simultaneously preventing pressure sores and promoting healing. The waterproof and breathable isolation membrane achieves a "breathable but not leaking" effect, keeping the surgical area dry and preventing fluid backflow that could damage the device, avoiding the risk of cross-infection and enhancing safety. The automatic pressure adjustment of each independent airbag within the cushions allows for digital management, standardizing and reproducible postoperative care, and enabling precise quantification of nursing care.

Detailed Implementation

[0026] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] like Figure 1-5As shown, a postoperative care device for dowager's hump includes a care plate 1, an air supply drive system, and a controller. The care plate 1 is connected to a strap 2, which allows the care plate 1 to be easily fixed to the head. The end of the strap 2 is fixed to the care plate 1. The strap 2 is flat and wide to facilitate pressure reduction and make it more comfortable to wear. A quick-release buckle assembly 21 is provided in the middle of the strap 2 for easy and quick putting on and taking off.

[0029] The nursing panel 1 includes a rigid outer shell 11 and a skin-friendly breathable layer 12 that fit together. The rigid outer shell 11 is made of ABS or carbon fiber. The rigid outer shell 11 has a recessed cavity 111 adapted to the surgical area of ​​the scrotum. The rigid outer shell 11 provides effective support, even when the patient is in a supine position, while the recessed cavity 111 prevents direct pressure on the surgical area. Corresponding to the recessed cavity 111, an airbag 3 is exposed above the skin-friendly breathable layer 12. The side of the airbag 3 facing the surgical area of ​​the scrotum has a waterproof and breathable insulating membrane 4, which provides good waterproofing without affecting breathability. The waterproof and breathable insulating membrane 4 is made of expanded polytetrafluoroethylene (ePTFE), a commonly used medical material with good skin-friendliness. The air cushion 3 contains multiple independent airbags 31. Each independent airbag 31 is connected to a pressure sensor 5 between itself and the rigid outer shell. Each independent airbag 31 is connected to an air supply system. The pressure sensor 5 and the air supply system are electrically connected to a controller. The controller independently controls the pressure of each independent airbag 31 based on the pressure feedback from the pressure sensor 5, so that the air cushion 3 maintains a constant pressure with the surgical area of ​​the dowager's hump, which is beneficial to surgical recovery.

[0030] The air supply drive system includes an air pump, and each air pump is connected to an individual airbag 31 by an air supply pipe. Each air supply pipe is equipped with an air supply control solenoid valve electrically connected to the controller. The air pump pumps air, which inflates the individual airbags 31 via the air supply control solenoid valve. The air supply control solenoid valve can be a three-way, three-position solenoid valve, capable of pressurizing, holding, and depressurizing.

[0031] The multiple independent airbags 31 within the airbag cushion 3 consist of a central airbag 311 and multiple peripheral airbags 312. The central airbag 311 is positioned at the center of the recessed receiving cavity 111, and the multiple peripheral airbags 312 are arranged around the central airbag 311, with each peripheral airbag 312 being equidistant. The central airbag 311 can compress the surgical area of ​​the dowager's hump, and appropriate postoperative pressure can effectively prevent bleeding and fluid accumulation at the skin flap dissection surface. The pressure of the peripheral airbags 312 ensures that the airbag cushion 3 is fixed in position and will not deviate, while also providing a certain amount of pressure to the surgical area of ​​the dowager's hump.

[0032] The inner surface of the rigid outer shell 11 is provided with a reciprocating, serpentine-shaped tube groove 112. A ventilation tube is arranged within the tube groove 112, and multiple air outlets are arranged on the ventilation tube. The ventilation tube is connected to an air pump via an air-blowing solenoid valve. The air-blowing solenoid valve is electrically connected to a controller, which controls the opening of the air-blowing solenoid valve. The air from the air pump enters the ventilation tube through the air-blowing solenoid valve and is blown out through the air outlets. The air passes through the skin-friendly breathable layer 12 and is blown onto the human body, reducing humidity and temperature. Preferably, the tube groove 112 is arranged around the recessed receiving cavity 111. The airflow formed by the air blown out through the air outlets passes through the skin-friendly breathable layer 12 and is blown onto the healthy skin surface around the area of ​​the dowager's hump surgery, actively removing surrounding sweat and lowering local body temperature, thereby indirectly inhibiting glandular sweating in the core area of ​​the dowager's hump surgery. During this process, the hot and humid sweat generated in the core area of ​​the dowager's hump surgery naturally permeates and diffuses to the periphery of the recessed receiving cavity 111 through the waterproof and breathable isolation membrane 4 with a microporous structure, and is then quickly carried away by the surrounding airflow. This design ensures stable airbag pressure and an absolutely sterile environment in the core area of ​​the surgery for dowager's hump, while avoiding patient discomfort caused by external airflow directly blowing on the wound. The airbag cushion 3 is equipped with a temperature sensor 6 and a humidity sensor 7, which monitor temperature and humidity in real time and feed the data back to the controller, allowing the controller to control the opening of the air-blowing solenoid valve as needed. The air-blowing solenoid valve can be a two-position three-way solenoid valve, which can control the opening and closing of related pipelines.

[0033] Example 2

[0034] A method for controlling a postoperative care device for dowager's hump includes:

[0035] Step S01: Multiple modes are preset based on postoperative time. The pressure of each individual balloon is preset according to the mode. Different postoperative times require different optimal pressure environments. The mode is determined based on the postoperative time, and different modes set different pressures for the individual balloons, thus ensuring the surgical area of ​​the "dowager's hump" is in a pressure environment conducive to recovery. The preset pressure of the central balloon is 4 mmHg lower than that of the peripheral balloons. The center of the surgical area of ​​the "dowager's hump" is the area with the deepest skin flap dissection, the most severe damage to the vascular network, and the most vulnerable area. Fine-tuning and reducing the pressure in this area can maximize local microcirculation blood perfusion and avoid ischemia and necrosis of the central skin flap. Meanwhile, the peripheral balloons maintain a relatively high pressure, which on the one hand provides stable support and anchoring force for the nursing board, and on the other hand forms a "high-pressure water-blocking ring" around the surgical area, effectively preventing subcutaneous exudate from spreading to surrounding healthy tissue, thereby accelerating the closure and healing of the dead space in the central area, achieving an unexpected local healing-promoting effect.

[0036] Step S02: The pressure sensor feeds back the real-time pressure of each individual airbag to the controller. The controller adjusts the pressure of each individual airbag to the preset pressure range according to the mode. When the human body is in different positions, the gap between the airbag cushion and the surgical area of ​​the dowager's hump will change, resulting in pressure changes. The pressure sensor detects these changes in real time, so that the controller can control the air supply drive system to work according to the changes and control the pressure of each individual airbag.

[0037] Furthermore, step S01 includes three preset modes: an acute phase mode for days 0-2 post-surgery, a subacute phase mode for days 3-7 post-surgery, and a remodeling phase mode for days 7 and beyond post-surgery. The acute phase mode presets a pressure of 22-26 mmHg for the peripheral airbag, the subacute phase mode presets a pressure of 18-22 mmHg for the peripheral airbag, and the remodeling phase mode presets a pressure of 15-18 mmHg for the peripheral airbag. This setting allows switching between different modes depending on the post-operative time, thus providing a better recovery environment for the patient. Given that the normal capillary occlusion threshold in the human body is approximately 32 mmHg, this invention strictly controls the maximum pressure limit to 26 mmHg, completely eliminating the risk of ischemia, necrosis, and pressure ulcers caused by traditional bandages due to localized high pressure (often exceeding 32 mmHg). Simultaneously, maintaining effective compression of 22-26 mmHg during the acute phase can quickly close dead space and prevent post-operative hematoma. As the healing process progresses into the subacute and remodeling phases, the device gradually reduces pressure, satisfying tissue remodeling requirements while progressively releasing vascular pressure to accelerate lymphatic and blood return. This dynamic pressure reduction setting overcomes the shortcomings of traditional dressings with constant pressure, greatly optimizing the patient's recovery environment.

[0038] The control method for the postoperative care device for dowager's hump also includes step S03, where the temperature sensor and humidity sensor respectively feed back temperature and humidity information to the controller. For example, if the relative humidity is ≥70% or the skin temperature is ≥36.5℃, the controller controls the air blowing solenoid valve to open the ventilation tube for air blowing. When the relative humidity is ≤60%, the controller controls the air blowing solenoid valve to close. This setting can provide a better temperature and humidity environment for the surgical area.

[0039] The above embodiments are preferred implementations of the present invention and are not intended to limit the present invention. Any obvious substitutions are within the protection scope of the present invention without departing from the inventive concept.
