Description

Technical Field

[0001] The present application relates to the field of medical devices, and more specifically, to an auxiliary device for patients after pelvic fracture surgery. Background Art

[0002] Because the center of the fracture site of pelvic fracture is close to the internal organs, patients with pelvic fractures often use external fixators to fix the pelvic fracture site. In order to avoid displacement of the fracture site, patients need to lie flat for a long time. Even patients with comminuted pelvic fractures need to lie supine for 3 months. In the process of caring for patients with pelvic fractures, in order to prevent patients from lying flat for a long time and developing pressure sores, patients need to be turned over regularly. However, because the patient's pelvic fracture site is fixed with steel nails, he cannot move on his own and needs the help of family members or medical staff to turn over.

[0003] In the prior art, most of the products focus on the auxiliary turning function after pelvic fracture. By setting a turning bed body, a turning sheet and a placement groove, it is convenient for patients with pelvic fracture to lie on it. By setting a small driver, the rotating shaft can be driven to rotate. By setting a control panel, a rotating shaft and a wire, it is convenient to control the rotation of the rotating shaft, and the turning sheet is wrapped so that the patient on the turning sheet can turn over, thereby achieving the effect of assisting turning over. At the same time, some products also use a pure cotton layer and a breathable layer with a hole-like structure evenly opened inside, which can facilitate the liquid to be quickly absorbed by the water-absorbing layer. Since the water-absorbing layer is arranged in a wavy structure, it can effectively increase the contact area with the liquid and has a stronger absorption capacity for liquid. Through the elastic layer of latex material, although the use of the turning device can make the patient more comfortable when turning over, the turning device will still be in contact with the external fixator of the pelvic fracture, which may cause the pelvic fracture to be displaced due to stress stimulation, which has hidden dangers for the healing of the patient's fracture site and cannot meet the patient's urination and defecation needs.

[0004] Therefore, it is of great significance to study an auxiliary device that can assist patients in turning over while effectively protecting the external fixator from stress stimulation, and can also meet the patients' needs for urination and defecation on the bed. Utility Model Content

[0005] The invention of this application aims to comprehensively improve the back pain and discomfort caused by long-term bed rest in patients with pelvic fractures, assist patients in turning over while effectively protecting the external fixator from stress stimulation, reduce the occurrence of lumbar and sacral pressure ulcers, and also meet the patients' needs for urination and defecation on the bed.

[0006] The present application provides an auxiliary device for patients after pelvic fracture surgery, comprising:

[0031] The structure and effect of the present application are further described in detail below in conjunction with the embodiments. It is to be understood that the specific embodiments described herein are only used to explain the invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention rather than the entire structure are shown in the accompanying drawings.

[0032] Example

[0033] The present application embodiment discloses an auxiliary device for patients after pelvic fracture surgery, referring to Figure 1 The auxiliary device includes a bed body 1, a support plate 2, a support frame 3, a telescopic component 4, a fixing plate 5, a railing 6, a protective strip 7 and a controller 8.

[0034] The bed body 1 is a prior art, which includes a bed body, a bed head and bed legs. The attached figure is a schematic diagram, so part of the structure of the bed body 1 is hidden. A receiving groove 11 is provided in the middle of the top surface of the bed body 1. The receiving groove 11 is arranged corresponding to the support frame 3, so that the support frame 3 can enter the receiving groove 11. When the support frame 3 enters the receiving groove 11, a certain amount of gap can be left at the edge, thereby avoiding the support frame 3 being obstructed by the edge of the receiving groove 11 when the support frame 3 is raised or lowered. The depth of the receiving groove 11 can be set as needed, but it should be noted that when the support frame 3 is retracted by the telescopic component 4 and stored in the receiving groove 11, the surface of the support frame 3 is coplanar with the surface of the bed body 1, thereby ensuring that the patient's normal lying is not disturbed by the height difference, thereby improving the comfort.

[0035] The support plate 2 is arranged at the bottom of the receiving groove 11, and the telescopic assembly 4 is arranged on the support plate 2, and is used to control the lifting of the support frame 3. The telescopic assembly 4 includes two groups of lifting units 41, and each group of lifting units 41 includes at least two lifting rods 411. The top of the lifting rod 411 is connected to the support frame 3 through the connecting assembly 9. The connecting assembly 9 includes a fixed part 91 fixedly arranged at the bottom of the support frame 3 and a connecting part 92 fixedly arranged at the end of the lifting rod 411. The connecting part 92 is rotatably connected to the fixed part 91. The structure of the fixed part 91 and the connecting part 92 can be an existing structure. For example, the fixed part 91 is composed of two ear plates fixedly arranged at the bottom of the support frame 3 and a fixed rod fixedly arranged between the two ear plates. The connecting part 92 is composed of two ear plates fixedly arranged at the end of the lifting rod 411. The two ear plates of the connecting part 92 are both provided with holes, and the fixing rod of the fixed part 91 is passed through the two holes to realize rotation.

[0036] The fixing plate 5 is arranged on the support frame 3 corresponding to the perineum of the patient, and the middle part is a hollow structure for the patient to excrete. Two railings 6 are provided, and are respectively arranged on both sides of the support frame 3. The provision of the railings 6 effectively reduces the occurrence of the patient falling during the turning process, and can be used as a patient support handrail. The protective strip 7 is arranged between the two railings 6, and is used to fix the patient, and there are multiple protective strips 7. A human body pressure tester is provided on the protective strip 7, and the protective strip 7 can be tightened according to the appropriate pressure test value. This structure is also a prior art. Alternatively, the protective strip 7 selects a protective strip 7 similar to the structure of a car seat belt.

[0037] The controller 8 is electrically connected to the telescopic assembly 4 and is used to control the lifting and lowering of the telescopic rod. The controller 8 is provided with a button for manipulating the lifting and lowering of each lifting unit 41 individually and a button for manipulating the synchronous lifting and lowering of the two groups of lifting units 41. Such a configuration can meet the lifting and lowering of the support frame 3 and the turning of the patient. For greater safety, when the two groups of lifting units 41 are lifted and lowered individually, the bevel angle of the support frame 3 does not exceed 45°, and this limitation can be achieved by adjusting the lifting height of the lifting rod 411. In order to facilitate wiring, a plurality of through holes are provided at the bottom of the support plate 2, and the plurality of through holes are provided corresponding to the lifting rod 411, and the power cord of the lifting rod 411 is connected to the lifting rod 411 through the through holes.

[0038] The implementation principle of the present invention is: when a patient with a pelvic fracture wants to turn over or improve the discomfort in the waist and back, he presses the switch button of the controller 8 with his free upper limbs, and drives the telescopic component 4 separately or synchronously to move, so that the support frame 3 is raised or lowered or turned over, thereby realizing the patient's "turning over". At this stage, the maximum turning over safety angle is set to 45° to ensure the safety of the patient. During the turning over process, the patient is fixed by the protective strip 7, which effectively reduces the displacement of the pelvic fracture due to stress stimulation, and the protective strip 7 has a human body pressure tester, which can tighten the protective strip according to the pressure test value, making it more convenient to use. If the patient needs to urinate or defecate, the two groups of telescopic units can be driven to start synchronously through the controller 8, so that the support frame 3 is raised a certain distance, and then the bedpan can be placed under the hollow structure of the fixed plate 5. It is easy to use and effectively improves the convenience of the patient's toilet.

[0039] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
