Description

Technical Field

[0001] The present disclosure belongs to the technical field of medical devices, and in particular relates to an auxiliary device for preventing pressure sores. Background Art

[0002] Pressure ulcers are caused by long-term pressure on local tissues, resulting in continuous ischemia, hypoxia, and malnutrition, leading to tissue ulceration and necrosis. Skin pressure ulcers are a common problem in rehabilitation treatment and nursing. Therefore, helping bedridden patients to turn over can effectively alleviate the formation of pressure ulcers.

[0003] An existing patent (publication number CN212186976U) and a nursing anti-pressure sore auxiliary turning device, this patent sets an anti-pressure sore auxiliary turning device support structure, an anti-pressure sore auxiliary turning device rotation structure, an anti-pressure sore auxiliary turning device power structure and other structures to cooperate with each other to form a device that can assist the injured to turn over by themselves, save manpower, and reduce the burden of nursing work. The above patent pushes people to turn over through a support rod, and the person and the support rod are in rigid contact. At the same time, the human body is an elastic body. Pushing the body to turn over through a single area and rigid contact can easily cause soft tissue contusion. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an auxiliary device for preventing pressure sores, which uses a blanket to assist the patient to turn over, thereby alleviating pressure sores caused by long-term pressure on the patient's local tissue. The blanket has a large contact area with the patient's body and there is no rigid contact, so that rigid contact can be avoided during the turning process to prevent soft tissue contusion.

[0005] The purpose of this disclosure can be achieved through the following technical solutions:

[0006] An auxiliary device for preventing pressure sores, comprising:

[0007] A turning blanket, wherein a plurality of hanging rings are fixedly connected to both sides of the turning blanket;

[0008] A support frame, a cross beam is provided at the upper end of the support frame, a slide groove is opened on the cross beam along its length direction, a slider is slidably connected in the slide groove, a screw rod is provided in the slide groove along its length direction, both ends of the screw rod are rotatably connected to the end of the cross beam, the screw rod passes through the slider and is threadedly connected to the slider, the lower end of the slider is fixedly connected to a fixed block, telescopic sleeve rods are fixedly connected to both sides of the fixed block, and a rope is fixedly connected to the lower end of the fixed block and the end of the telescopic sleeve rod away from the fixed block.

[0009] The above technical solution, its principle and technical effect:

[0010] A turning blanket is laid under the patient in advance. When the patient needs to be turned over, the support frame is set up on the side of the bed and fixed to the side of the bed, the lower ends of the ropes are fixed to the corresponding hanging rings respectively, and the screw is driven to rotate by a driving source. The screw causes the slider to move along the direction of the slide groove, and the side connected to the turning blanket is pulled in one direction, so that the turning blanket is used to assist the patient in turning over.

[0011] In a preferred example, the utility model can be further configured as follows: one end of the screw rod is fixedly connected to the output end of the motor, and the motor is fixedly connected to the crossbeam.

[0012] In a preferred example, the utility model can be further configured as follows: a hook is fixedly connected to the lower end of the rope.

[0013] In a preferred example, the utility model can be further configured as follows: two limit plates are fixedly connected to the inner wall of the lower end of the support frame, a clamping plate is arranged between the two limit plates, and the upper end of the clamping plate is rotatably connected to a threaded column, and the threaded column passes through the upper limit plate and is threadedly connected thereto.

[0014] In a preferred example, the present invention can be further configured as follows: a rotating member is fixedly connected to the upper end of the threaded column.

[0015] In a preferred example, the utility model can be further configured as follows: one end of the crossbeam is fixedly connected to a lug plate, and the upper end of the support frame is rotatably connected to the lug plate.

[0016] In a preferred example, the utility model can be further configured as follows: bolts are threadedly connected to the ear plate, and two limiting holes for inserting the bolts are provided at the upper end of the crossbeam.

[0017] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0018] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0019] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0020] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0021] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0022] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0023] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0024] Beneficial effects of the present disclosure:

[0025] Blankets are used to assist patients in turning over, alleviating pressure ulcers caused by long-term pressure on the patient's local tissues. The blanket has a large contact area with the patient's body and there is no rigid contact, which avoids rigid contact and soft tissue contusion during the turning process.
