Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a perioperative nursing and turning assistance device for orthopedic bone tumor patients. Background Technology

[0002] Bone tumors are tumors that occur in the bones or their surrounding tissues. Malignant bone tumors, commonly known as "bone cancer," develop rapidly, have a poor prognosis, and a high mortality rate. They are a type of malignant tumor that primarily affects children and adolescents, with an incidence rate of only three per million. Our hospital's Department of Bone Tumors pioneered and implemented multi-joint replacement surgeries, including artificial shoulder, hip, knee, and elbow replacements, for tumor-related conditions. We also developed various limb-sparing methods for malignant tumors. While improving limb salvage rates, this approach has also presented significant challenges to perioperative clinical nursing care.

[0003] Bone tumor patients often suffer from prolonged bed rest, limited mobility, and severe impairment of self-care abilities due to pain, functional impairment, deformity, and pathological fractures. In severe cases, pressure injuries to the skin can occur. To address this, turning assistance devices such as triangular pillows, U-shaped pillows, or pressure-reducing mats are used. For example, Chinese invention patent 201310349929.0 discloses a breathable turning mat, which includes a right-angled triangular prism with ventilation holes on its slope. This is the most common triangular pillow-shaped turning mat. However, during use, multiple people are required to operate it to complete the patient's turning action, which requires a lot of manpower and resources and is difficult to cope with the near-total disability of bone tumor patients in clinical care. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a perioperative nursing turning assistance device for orthopedic bone tumor patients. It aims to solve the problem that the existing triangular pillow requires multiple people to operate in order to complete the turning action of the patient, which requires a lot of manpower and resources and is difficult to cope with the near-total disability of bone tumor patients in clinical nursing.

[0006] (2) Technical solution

[0007] To address the aforementioned technical problems, this utility model provides a perioperative nursing turning assistance device for orthopedic bone tumor patients, comprising an elastic pad. The elastic pad includes an insertion bucket for insertion into the patient's back, a pressure-bearing support connected to the insertion bucket, an abutment connected to the pressure-bearing support, and a plane at the end of the abutment. The insertion bucket includes a tip and a transition portion connected to the tip. The tip includes a bottom plane and an upper surface, forming an angle of 6-8°. The transition portion includes a bottom plane and an upper surface, forming an angle of 13-15°.

[0008] Preferably, the bottom surface of the pressure-bearing support and the bottom surface of the abutment are arc surfaces.

[0009] Furthermore, the thickness of the pressure-bearing support increases as it approaches the abutment, and the thickness of the abutment increases as it moves away from the pressure-bearing support.

[0010] Furthermore, the end of the abutment portion is provided with an upper extension support portion, and the upper extension support portion has a lateral protrusion on the side facing the pressure-bearing support portion.

[0011] Furthermore, the upper surface of the pressure-bearing support is provided with multiple arc-shaped protrusions.

[0012] Furthermore, the elastic pad has an inner layer and an outer layer, the outer layer being made of polyurethane foam and the inner layer being made of HIPS high-impact polystyrene.

[0013] Furthermore, the polyurethane foam is a low-density PU with a foam density of less than 18 kg / m3.

[0014] Furthermore, handles are fixedly connected to both the front and rear sides of the elastic pad.

[0015] Furthermore, the handle is made of 600D nylon webbing, and the 600D nylon webbing is bonded and fixed to the elastic pad with epoxy resin soft glue.

[0016] Furthermore, hook and loop fasteners are fixedly connected to both the front and rear sides of the abutment, and hook and loop fasteners corresponding to the hook and loop fasteners are fixedly connected to the handle.

[0017] Beneficial effects

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention utilizes polyurethane foam as the outer layer of the elastic pad, with 8-10 sets of semi-circular foam protrusions providing a soft feel, a highly porous structure, and good resilience. This allows for effective drainage of epidermal sweat and keeps the patient's skin dry and cool during prolonged use, support, and contact. Additionally, the elastic pad features double-sided handles on both the front and back, secured with 600D nylon webbing, facilitating easy carrying and use by nursing staff and allowing for convenient drying and storage after cleaning and disinfection.

[0020] This invention utilizes an insertable bucket that is inserted into the patient's back. Medical staff then move to the other side of the patient's bed, reaching under the bucket to pull it out until it protrudes. The patient is then gently and slowly turned over. Because of the pressure-bearing support, the patient is consistently supported during the turning process until the turning is complete, at which point the support part provides further support. The entire operation can be completed by a single medical staff member, significantly improving their work efficiency. Attached Figure Description

[0028] This specific embodiment is a perioperative turning assistance device for orthopedic bone tumor patients, and its structural schematic diagram is shown below. Figures 1-4 As shown, the device includes an elastic pad 1, which comprises an insertion bucket 11 for insertion into the patient's back, a pressure-bearing support 12 connected to the insertion bucket 11, an abutment 13 connected to the pressure-bearing support 12, and a plane 14 at the end of the abutment 13. The insertion bucket 11 includes a tip 111 and a transition portion 112 connected to the tip 111. The tip 111 includes a bottom plane 1111 and an upper surface 1112, which form an angle of 6-8°. The transition portion 112 includes a bottom plane 1121 and an upper surface 1122, which form an angle of 13-15°. Figure 4 As shown, the angle of the tip 111 is preferably 7 degrees and the angle of the transition part 112 is preferably 15 degrees, which not only makes it easy to scoop into the patient's lower back, but also helps the patient to turn over and move around while leaning on the device.

[0029] To facilitate the patient's turning over, such as Figure 2 and Figure 3 As shown: In this embodiment, the bottom surface of the pressure-bearing support 12 and the bottom surface of the abutment 13 are arc surfaces. The thickness of the pressure-bearing support 12 increases as it approaches the abutment 13, and the thickness of the abutment 13 increases as it moves away from the pressure-bearing support 12.

[0030] When using it, pull the insertion bucket 11 through under the patient until it is exposed, and then gently and slowly turn the patient over. Because the bottom is curved, it can reduce the force of turning over, making it more convenient to use.

[0031] like Figure 1 and Figure 2 As shown: In this embodiment, the end of the abutment portion 13 is provided with an upper extension support portion 15, the side of the upper extension support portion 15 facing the pressure support portion 12 is provided with a lateral protrusion 151, and the upper surface of the pressure support portion 12 is provided with a plurality of arc protrusions 16.

[0032] The number of protrusions is not limited to 8 and can also be 10. During the turning process, the patient's back is placed on 8-10 closely arranged semi-circular foam protrusions, which can reduce and improve the pressure on the patient's trunk and limbs and bony prominences.

[0033] To avoid the skin becoming damp, sticky, and smelly due to pressure on the skin of patients who are bedridden for a long time, such as... Figure 1 and Figure 5 As shown: In this embodiment, the elastic pad 1 has an inner layer 101 and an outer layer 102. The outer layer 102 is made of polyurethane foam, and the inner layer 101 is made of HIPS high-impact polystyrene. The polyurethane foam is a low-density PU with a foam density of less than 18 kg / m3.

[0034] By using polyurethane foam as the contact surface material for the outer layer 102 of the elastic pad 1, the 8-10 sets of protrusions have a soft feel, a highly porous structure, and good resilience, which can effectively expel epidermal sweat and keep the skin dry and cool when the patient relies on, supports, or contacts it for a long time.

[0035] To facilitate lifting of the elastic pad 1, such as Figure 1 As shown: In this embodiment, handles 17 are fixedly connected to both the left and right sides of the elastic pad 1. The handles 17 are made of 600D nylon webbing. The 600D nylon webbing is bonded to the elastic pad 1 with epoxy resin soft glue. By designing double handles 17 on the front and back sides of the elastic pad 1 and bonding them with 600D nylon webbing, it is convenient for nursing staff to carry and use, and it is also convenient to dry and store after cleaning and disinfection.

[0036] like Figure 6 As shown: In this embodiment, hook and loop fasteners 171 are fixedly connected to both the front and rear sides of the abutment part 13, and hook and loop fasteners corresponding to the hook and loop fasteners 171 are fixedly connected to the handle 17. In this way, when the handle 17 is bent to the side during use, it is fixed by the cooperation of the hook and loop fasteners 171 and the hook and loop fasteners, which prevents the handle 17 from bending to the bottom of the elastic pad 1. When turning over, it rolls better along the arc-shaped bottom and does not affect the use of the device.

[0037] Working Principle: Our assistive device, when the patient is lying flat and needs to be turned over, first inserts the insertion bucket 11 into the patient's back. Then, the medical staff moves to the other side of the bed and pulls the insertion bucket 11 under the patient until it is exposed. The patient is then gently and slowly turned over. Because of the pressure support 12, the patient's body is consistently supported during the turning process until the turning is complete. At this point, the abutment 13 provides support. The pressure support 12 is located under the patient's body, and the abutment 13 provides support for the patient's back. The entire operation can be completed by one medical staff member, significantly improving the efficiency of medical personnel. The efficiency of turning over is limited. Existing triangular pillow-structured turning mats only provide support after the patient has turned over, offering little assistance. More importantly, turning over requires the cooperation of several people: one person needs to operate the triangular pillow to assist in turning, and another person needs to turn the patient over. The turning over is completed through mutual cooperation. While common thin turning mats on the market can be used by one person to turn the patient over, they cannot provide adequate support during the turning process. This is unacceptable for patients with bone tumors. In other words, common thin mats are not the preferred choice for turning over patients with bone tumors.

[0038] Because tumors affect the development and strength of limb bones, leading to deformities, especially in the lower limbs, this device is available in trunk and limb models. The trunk model is shortened, while all other parameters remain the same. It is specifically designed for use after limb bone tumor surgery or in cases of combined deformities. It can be used in parallel with the trunk model to aid in clinical nursing and perioperative functional recovery. Model A is for trunk use, with dimensions of 1200mm*350mm*680mm and a total weight of 1300g. Model B is for limbs, with dimensions of 600mm*350mm*680mm and a total weight of 650g.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
