Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a bandage dressing auxiliary device for pressure treatment of lymphedema. Background Technology
[0002] Lymphedema is a chronic disease caused by dysfunction of the lymphatic system. As a key part of the human immune system, the lymphatic system plays a vital role in transporting lymph fluid, maintaining fluid balance, and participating in immune responses. When the lymphatic system malfunctions and lymph fluid cannot flow back properly, lymphedema occurs. Currently, bandaging is an important treatment method. However, during the maintenance phase after bandaging, due to the structure of the joints, uneven pressure distribution can easily occur at prominent joint areas, leading to adverse reactions such as pressure sores. For example, at the medial and lateral malleoli, after bandaging, pressure tends to concentrate at the bony prominences of the malleoli, while the depressions below the malleoli receive insufficient pressure.
[0003] The prior art CN215915244U discloses a lymphedema bandage binding aid, which has a flexible layer on the inner side of the main body and is filled with fluid. When the main body is wrapped around the area to be bound, the flexible layer will conform to the human body. As the bandage is tightened, the flexible layer will be compressed, and the fluid inside will flow according to the shape of the joint. The fluid in the bone position will flow to the concave position, balancing the pressure and avoiding adverse reactions such as pressure damage.
[0004] Regarding the aforementioned bandage application aids for lymphedema, since the bandaging process mainly relies on the nurse's experience, the bandage pressure is prone to uneven distribution, leading to local ischemia, affecting the treatment effect, and even causing complications. Utility Model Content
[0005] The purpose of this invention is to provide an auxiliary device for bandaging in the treatment of lymphedema pressure, which solves the problem that the bandage pressure is easily unevenly distributed due to the reliance on the nurse's experience during the bandaging process, leading to local ischemia, affecting the treatment effect and even causing complications.
[0006] To achieve the above objectives, this utility model provides a bandage dressing auxiliary device for pressure therapy of lymphedema, including an outer bandage and a dressing assembly. The dressing assembly includes an inner bandage, a pressure sensor, an airbag, a feedback component, and a monitoring component. The inner bandage is disposed on one side of the outer bandage. The pressure sensor is disposed between the inner and outer bandages. The airbag is disposed on the inner bandage and located on the side of the inner bandage away from the outer bandage. The feedback component is disposed on the outer bandage, and the monitoring component is mounted on the inner bandage.
[0007] The feedback component includes a light strip and a vibration motor. The light strip is disposed on the outer bandage and located on the side of the outer bandage away from the pressure sensor. The vibration motor is disposed on the outer bandage and located on the side of the outer bandage closer to the light strip.
[0008] The bandaging assembly also includes a fluorescent arrow, which is disposed on the outer bandage and located on the side of the outer bandage closest to the light strip.
[0009] The bandaging assembly further includes a humidity sensor and a temperature sensor. The humidity sensor is disposed on the inner bandage and located on the side of the inner bandage closer to the airbag. The temperature sensor is disposed on the inner bandage and located on the side of the inner bandage closer to the humidity sensor.
[0010] The bandaging assembly also includes a silicone protective layer, which is disposed between the outer bandage and the inner bandage and encloses the pressure sensor.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0018] The embodiment of this application is as follows:
[0019] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the bandage dressing auxiliary device for pressure therapy of lymphedema according to this utility model. Figure 2 This is a structural schematic diagram of the pressure sensor 103 of this utility model. Figure 3 This is a structural schematic diagram of the monitoring component of this utility model.
[0020] This utility model discloses an auxiliary bandage device for pressure therapy of lymphedema, comprising an outer bandage 101, an inner bandage 102, a pressure sensor 103, an airbag 104, a light strip 105, a vibration motor 106, a fluorescent arrow 107, a humidity sensor 108, a temperature sensor 109, and a silicone protective layer 110. It solves the problem that during bandaging, the reliance on nurses' experience leads to uneven bandage pressure distribution, resulting in local ischemia, affecting treatment effectiveness, and even causing complications. It is understood that the aforementioned solution can also be used to address the issues of high operational barriers and uneven pressure associated with traditional bandage techniques.
[0021] In this embodiment, the outer bandage 101 is made of elastic fibers and is placed on the outer bandage 101 by the bandaging component, thereby solving the problem that the bandage pressure is easily unevenly distributed due to the reliance on the nurse's experience during the bandaging process, which can lead to local ischemia, affect the treatment effect, or even cause complications.
[0022] The inner bandage 102 is disposed on one side of the outer bandage 101. The pressure sensor 103 is disposed between the inner bandage 102 and the outer bandage 101. The airbag 104 is disposed on the inner bandage 102, located on the side of the inner bandage 102 away from the outer bandage 101. The feedback component is disposed on the outer bandage 101. The monitoring component is mounted on the inner bandage 102. The inner bandage 102 is made of memory foam. The pressure sensor 103 is a flexible piezoresistive sensor array, disposed between the outer bandage 101 and the inner bandage 102 in a grid distribution (5cm × 5cm interval), used to monitor the pressure value of each area in real time. The pressure sensor 103 is connected to an external processor. The system is equipped with a Bluetooth module for external processing. The data monitored by the pressure sensor 103 is fed back to the external processor. After processing by the external processor, the specific pressure value can be transmitted to a dedicated APP via the Bluetooth module. The airbag 104 is set on the inner bandage 102 and connected to an external micro air pump. The external micro air pump can dynamically inflate and deflate the airbag to increase the pressure. The feedback component is used to provide feedback on the pressure status. The monitoring component can monitor the temperature and humidity of the skin in real time. By combining the pressure sensor 103 and the airbag 104, precise control of the bandage pressure can be achieved. This solves the problem that during the bandaging process, the bandage pressure is easily unevenly distributed, leading to local ischemia, affecting the treatment effect, and even causing complications, because the main reliance is on the nurse's experience.
[0023] Secondly, the light strip 105 is disposed on the outer bandage 101 and located on the side of the outer bandage 101 away from the pressure sensor 103; the vibration motor 106 is disposed on the outer bandage 101 and located on the side of the outer bandage 101 close to the light strip 105. The light strip 105 is an LED light strip 105, distributed along the edge of the outer bandage 101, and is used for pressure indication. When the light strip 105 is green, it indicates that the pressure is normal. When the light strip 105 is red, it indicates that the pressure needs to be adjusted. The vibration motor 106 is used for lifting and vibrating, and triggers intermittent vibration warning when there is overpressure. Through the light strip 105 and the vibration motor 106, corresponding feedback can be given according to the pressure.
[0024] Meanwhile, the fluorescent arrow 107 is disposed on the outer bandage 101 and located on the side of the outer bandage 101 close to the light strip 105. The fluorescent arrow 107 is woven from fluorescent threads and can emit light in the dark. The fluorescent arrow 107 is sewn on the outer bandage 101 along its length to indicate the bandaging direction and prevent the bandage from wrapping in the opposite direction. The fluorescent arrow 107 can thus indicate the direction of bandaging.
[0025] In addition, the humidity sensor 108 is disposed on the inner bandage 102 and located on the side of the inner bandage 102 close to the airbag 104; the temperature sensor 109 is disposed on the inner bandage 102 and located on the side of the inner bandage 102 close to the humidity sensor 108. The humidity sensor 108 and the temperature sensor are also connected to an external processor. The humidity sensor 108 is used to monitor the amount of sweat produced by the skin and prompts the user to change the bandage via the APP. The temperature sensor 109 is used to monitor the skin temperature. When the local temperature rises above 1.5°C, the user is prompted by the APP to warn of the risk of infection. Through the humidity sensor 108 and the temperature sensor 109, real-time monitoring of skin temperature and humidity can be achieved.
[0026] Finally, the silicone protective layer 110 is disposed between the outer bandage 101 and the inner bandage 102, and wraps the pressure sensor 103. The silicone protective layer 110 wraps the pressure sensor 103, thereby protecting the pressure sensor 103.
[0027] In this embodiment, the application employs a flexible circuit, replacing traditional wires with laser-engraved conductive ink, which can withstand bending more than 100,000 times. The external processor has a pre-set bandaging program suitable for both the acute and long-term postoperative periods. During use, the appropriate mode can be selected based on the patient's specific condition. In use, following the direction of the fluorescent arrow 107, the bandage is wrapped around the patient's upper limb, starting from the wrist, elbow, and armpit. As the bandage is wrapped, the arrow illuminates segment by segment. The pressure sensor 103 monitors the pressure in real time, and the corresponding LED strip 105 illuminates according to the pressure status. Red indicates overpressure, and the vibration motor 106 synchronously triggers an intermittent vibration warning, requiring adjustment. Green indicates normal pressure, and subsequent wrapping can continue. Additionally, the airbag 104 can adjust the pressure of localized bulges (the airbag 104's adjustment logic: when the pressure in a certain area exceeds the standard, adjacent airbags 104 automatically deflate, while the distal airbag 104 pressurizes to maintain overall pressure balance). By cooperating with the airbag 104, the pressure sensor 103 can be precisely controlled to control the pressure of the bandage. This solves the problem that the bandage pressure is easily unevenly distributed, leading to local ischemia, affecting the treatment effect, or even causing complications, because the bandage process mainly relies on the nurse's experience.
[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
