[0002] At present, in the daily nursing work in the medical field, the dressing change for the patients with hip joint diseases or postoperative recovery is a crucial link. In this process, the patient is usually required to maintain a side-lying posture, so that the medical staff can accurately and effectively treat the wound. However, in order to ensure that the side-lying posture of the patient is stable during this process, and to avoid unnecessary movement or distortion that may cause secondary injury to the wound, certain measures must be taken to properly support and fix the patient's legs, especially the knee joints.
[0003] At present, medical practice mainly relies on fixed pads, support pads and fixed belts and other equipment to complete this task. The basic design intention of these devices is to solve the problem of fixing the patient when lying on one side, and to ensure that the dressing change process can proceed smoothly. However, in actual application, these devices often fail to provide ideal comfort, stability and operational convenience at the same time, thereby affecting the patient's nursing experience and recovery effect to some extent.

[0037] As shown in FIG. 1, Figure 1 The embodiment of the utility model provides a hip joint dressing auxiliary device, including support 100, clamping assembly 200.
[0038] The support 100 has two support parts arranged in the vertical direction, and the two support parts are used to provide lifting support for the two knee joints of the patient when lying on the side; the upper end of the support 100 is provided with a placing surface 110; the clamping assembly 200 is arranged correspondingly with the support part, and the clamping assembly 200 is used to clamp and fix the knee joint when the support part lifts and supports the knee joint of the patient.
[0039] The hip joint dressing change auxiliary device provided by the embodiment, when the hip joint region of the patient needs to be changed or dressed, first, the medical staff will guide the patient to take a side-lying position and lie stably on the bed. Then, the two knee joints of the patient are placed in the corresponding support part positions. Next, the clamping assembly 200 on the support 100 can gently and firmly clamp the patient's knee joint. This design not only further stabilizes the patient's lower limbs, but more importantly, effectively avoids the mutual extrusion of the patient's legs in the side-lying state due to direct contact, thereby reducing the discomfort of the patient.
[0040] Through this series of designs, the patient can maintain the body position more easily and durably in the side-lying state, which is crucial for medical staff. It ensures that medical staff can have a clearer operating field of view when treating the hip joint wound, thereby achieving the accuracy and effectiveness of wound treatment. In addition, the embodiment also provides a placement surface 110 on the support 100, which can be used to place related medicines, consumables and tools. Such a layout enables medical staff to quickly and conveniently access the required items during dressing change, without the need to frequently get up or bend down to look for them, thereby significantly improving work efficiency.
[0041] In some specific embodiments, the support part includes two through support grooves 120, and the axes of the two support grooves 120 are arranged in parallel. This design ensures that when the patient's knee joint is placed in the support groove 120, it can enjoy uniform and stable support force, which is conducive to maintaining the stability of the patient's body position during dressing change. The side wall of the support groove 120 is provided with a placement opening 121, and the patient's knee joint can pass through the placement opening 121 by translation to enter the support groove 120. The design width of the placement opening 121 is moderate, which not only ensures that the patient's knee joint can easily and smoothly pass through the translation action to enter the inside of the support groove 120, but also avoids the problem of weakened support due to the opening being too large. The medical staff only need to align the patient's knee joint with the placement opening 121 and slightly translate it to place the knee joint in the corresponding support groove 120, thereby achieving a stable support state, greatly simplifying the operation process and improving the convenience of use.
[0042] As shown in Figure 2 In some specific embodiments, the cross-sectional area of the middle part of the support groove 120 is greater than the cross-sectional area of the two through openings of the support groove 120. This is because the knee joint part of the human body usually presents a shape similar to a bamboo joint, that is, the middle part is relatively thick, and the two ends are relatively small.
[0043] Therefore, the middle part of the support groove 120 is designed to be relatively wide and large in shape to better adapt to the natural curve of the patient's lower limbs at this critical position. Such a design not only ensures that the patient can feel high comfort and fit when receiving support, but also substantially improves the support effect. By tightly wrapping the knee joint of the patient in the middle part of the support groove 120, the shaking or sliding caused by unstable support is effectively reduced, thereby providing more stable and reliable support for the patient's lower limbs.
[0044] In addition, this design also fully considers the actual needs of patients during use. Since the knee joint is one of the more complex and easily damaged parts of the human body, it is particularly important to provide sufficient and appropriate support. The special shape of the support groove 120 meets this need, making patients feel more secure when receiving support, and also provides more convenience for medical personnel.
[0045] In some specific embodiments, the end surface of the bracket 100 away from the placement opening 121 is a convex arc surface; in actual application, patients may change from a side-lying position to a flat-lying position due to sudden changes in the external environment, such as the operation of medical personnel, the movement of equipment, or the adjustment of their own body state. In this process, if the end surface of the bracket 100 is flat or sharp, the patient may be uncomfortable or even injured when the lower limbs come into contact with the bed surface due to excessive impact.
[0046] By designing the end surface of the bracket 100 as a convex arc surface, this problem is effectively solved. When the patient changes from a side-lying position to a flat-lying position, the arc surface will come into contact with the bed surface first. Due to the shape characteristics of the arc surface, it can better disperse the impact force, making the transition process more gentle, thereby greatly reducing the potential harm to the patient's lower limbs.
[0047] In addition, this design also improves the safety of the embodiment. Patients can feel more secure when using it and do not have to worry too much about the potential risks caused by the change in posture. At the same time, this also provides more convenience for medical personnel, so that they can focus more on the treatment needs of the patient during the operation, without having to worry too much about the safety of the equipment.
[0048] In some specific embodiments, the clamping assembly 200 comprises a clamping air cushion 210 laid on the inner side wall of the support groove 120, which can closely fit the contour of the lower limb of the patient in the inflated state. Such design not only ensures the maximum contact area of the air cushion with the patient, but also enables the air cushion to uniformly distribute pressure after inflation, avoiding local compression or discomfort to the patient. The air pump is used to inflate the clamping air cushion 210, thereby driving the clamping air cushion 210 to clamp and fix the knee joint of the patient in the support groove 120; during the inflation process, the air pump gradually increases the air pressure in the clamping air cushion 210 according to the preset program or the instructions of medical staff, thereby driving the clamping air cushion 210 to gradually expand and tightly wrap around the knee joint of the patient. The process is gradual and controllable, ensuring uniform application of clamping force and avoiding discomfort or injury to the patient caused by sudden increase in pressure.
[0049] In some specific embodiments, the clamping air cushion 210 extends towards each other at both ends near the side opening of the support groove 120, respectively, with a blocking part 211; this design not only takes into account the basic functional requirements of the clamping air cushion 210, but also fully considers the convenience and safety of patient use.
[0050] Before the clamping air cushion 210 is inflated, its overall shape is relatively flat, closely fitted with the inner side wall of the support groove 120 but without causing additional obstruction. At this time, the clamping air cushion 210 and its extended blocking part 211 will not cause any blocking effect on the operation of placing the knee joint of the patient into the support groove 120. Such design enables the patient or medical staff to easily place the knee joint in the support groove 120, greatly improving the convenience of use.
[0051] When the knee joint of the patient is properly placed in the support groove 120, the inflation process of the clamping air cushion 210 begins. As the air pump continuously injects gas into the clamping air cushion 210, the air pressure in the clamping air cushion 210 gradually rises, causing it to begin to expand and tightly fit around the knee joint of the patient. In this process, the blocking part 211 also expands and gradually extends towards the placement opening 121 of the support groove 120.
[0052] The expansion of the blocking part 211 not only plays a role in plugging the placing opening 121 of the support groove 120, effectively avoiding the risk of the patient's lower limbs accidentally separating from the support groove 120, but also further enhances the clamping effect of the clamping air cushion 210 on the patient's knee joint. Specifically, when the blocking part 211 is fully inflated, it forms a stable and reliable support structure together with other positions of the clamping air cushion 210, which clamps and lifts the patient's knee joint in all directions. Such a design not only ensures the stability and safety of the patient during treatment or rehabilitation training, but also greatly improves the overall comfort.
[0053] In some specific embodiments, the bottom of the support 100 is provided with a support air cushion 130. By inflating the support air cushion 130 with the air pump, the contact area of the support air cushion 130 with the hospital bed is greater than the projected area of the support 100 relative to the hospital bed. This design makes the placement of the support 100 on the hospital bed more stable, effectively reducing the risk of the support 100 toppling due to external forces or patient movement. When the support air cushion 130 is in an uninflated state, its overall shape is flat and compact, occupying relatively less space. This feature allows the present embodiment to be more conveniently stored and stored when not in use.
[0054] In some specific embodiments, the bottom of the support 100 and the bottom of the support air cushion 130 are provided with a non-slip mat to increase the friction between the bottom of the support 100 and the hospital bed, reduce the probability of the support 100 sliding relative to the hospital bed, and improve the safety of the present embodiment.
[0055] In some specific embodiments, the clamping assembly 200 further includes a control panel 220, which is provided on the support 100. The control panel 220 is electrically connected to the air pump, and is used to control and adjust the opening and closing and power of the air pump, facilitating quick operation of the air pump.
[0056] In some specific embodiments, the clamping air cushion 210 is provided with a pressure sensor on the end face close to the patient's knee joint. The pressure sensor is electrically connected to the control panel 220, and through the control panel 220, the pressure data on the patient's knee joint can be observed in real time. This function not only helps medical staff to understand the stress condition of the patient in time, but also allows timely adjustment of the air pump as needed to ensure that the pressure on the patient's knee joint always remains within a safe and comfortable range. Such a design not only improves the safety of the present embodiment, but also greatly improves the user experience of the patient.
[0057] As Figure 3As shown, in some specific embodiments, the control panel 220 comprises a screen and a button; the screen can directly display the received data measured by the pressure sensor and the working time of the air pump, and the working state of the air pump can be controlled and adjusted by pressing the button; medical staff only need to press the button to quickly control and adjust the working state of the air pump. Such design not only simplifies the operation process, but also improves the use efficiency of users, so that the whole device is easier to use and use.
[0058] In some specific embodiments, the placing surface 110 is provided with a placing groove 140 for placing a dressing disc, so as to ensure that the dressing disc is stable and does not slide during operation, and is convenient for medical staff to use.
[0059] In some specific embodiments, the inner wall of the placing groove 140 is provided with an elastic layer, which can provide a certain extrusion force to the dressing disc when the dressing disc is placed in the placing groove 140, so as to further improve the placing reliability of the dressing disc.
