Abstract
Description
Technical Field
[0001] The utility model relates to human daily necessities, in particular to auxiliary medical equipment, in particular to an inflatable restraint device for preventing pressure sores. Background Art
[0002] Some psychiatric patients suffer from neurological diseases characterized by behavioral and psychological disorders. During treatment, these patients need to use auxiliary restraint devices to restrain their limbs to avoid hurting themselves or others.
[0003] The prior art generally uses restraint belts for restraint, but the restraint belts are tough and often cause strangulation marks and trauma to the patient's limbs.
[0004] There are also technical solutions in the prior art that use inflatable airbags to tightly clamp the patient's limbs. Compared with restraint belts, this technical solution can better protect patients from strangulation marks and trauma. For example, the existing patent (publication number CN211985851U) discloses a hand restraint belt for psychiatric care. Through the arrangement of airbags and air inlet pipes, the patient's arm is placed in the corresponding hollow area of the airbag, and then the airbag is inflated by connecting the air inlet pipe through an external air pump. The patient's arm is clamped by the airbag, and the arm is fixed by wrapping the airbag to avoid strangulation marks in the process of the patient's escape.
[0005] However, this type of technology also has some problems: the airbag being close to the patient's skin for a long time can cause pressure sores, and the airbag wrapping the skin and not being breathable can also easily cause skin diseases. Summary of the invention
[0006] The utility model aims to provide an inflatable restraint device for preventing pressure sores, which aims to solve the problems that the air bag may cause pressure sores when it is close to the patient's skin for a long time, and the air bag may easily cause skin diseases when it wraps the skin and is not breathable.
[0007] An inflatable restraint device for preventing pressure sores comprises a fixed cylinder, a rotating cylinder and an airbag cylinder; one end of the fixed cylinder is coaxially rotatably connected to one end of the rotating cylinder, and the other end of the rotating cylinder is connected to the airbag cylinder; more than two cylindrical airbags are arranged on the inner wall of the airbag cylinder; an inflation port is arranged on the outer wall of the airbag cylinder, and the inflation port is connected to the cylindrical airbag; the fixed cylinder is connected to a restraint belt.
[0008] Furthermore, a fixing ring is provided on the fixing tube, and a snap button is provided at one end of the restraining belt, and the snap button is connected to the fixing ring.
[0009] Furthermore, the number of the cylindrical airbags is three, and the bottoms of adjacent cylindrical airbags are connected.
[0010] Furthermore, skin-friendly pads are provided on the inner walls of the fixed cylinder and the rotating cylinder.
[0011] Beneficial Effects
[0012] Compared with the prior art, the utility model has positive and obvious effects:
[0013] 1. Reduce the contact area with the patient's skin through the cylindrical airbag.
[0014] 2. The contact position between the cylindrical airbag and the patient's skin is adjusted by the rotating device to prevent the cylindrical airbag from pressing on the same position for a long time and causing pressure sores. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following embodiments will further illustrate the present invention, but are not intended to limit the present invention.
[0021] like Figures 1 to 4 As shown, the present embodiment provides an inflatable restraint device for preventing pressure sores, comprising a fixed cylinder 1, a rotating cylinder 2 and an airbag cylinder 3; one end of the fixed cylinder 1 is coaxially rotatably connected to one end of the rotating cylinder 2, and the other end of the rotating cylinder 2 is fixedly connected to the airbag cylinder 3. A circle of convex rings is provided on the inner cylinder edge of the rotating cylinder 2, and a circle of grooves is provided on the outer cylinder edge of the fixed cylinder 1. The convex rings and the grooves are matched and connected, thereby realizing a coaxial rotation connection between the rotating cylinder 2 and the fixed cylinder 1.
[0022] Three long cylindrical airbags 4 are arranged on the inner wall of the airbag tube 3 along the direction parallel to the axis of the airbag tube 3, namely the first airbag 401, the second airbag 402 and the third airbag 403. The three cylindrical airbags 4 are adjacent to each other, and the bottoms of the adjacent airbags are connected. The cylindrical airbags 4 are long and flat when not inflated, and cylindrical when inflated. When the first airbag 401, the second airbag 402 and the third airbag 403 are inflated, they can fill the gap between the patient's limbs and the inner wall of the airbag tube 3, so as to achieve the effect of flexible restraint of the patient's limbs and avoid the marks caused by the restraint belt or the restraint ring directly restraining the patient; and the three cylindrical airbags 4 contact the patient's skin with strip contact surfaces from three directions around the patient's limbs, respectively, and there are gaps between adjacent strip contact surfaces, so that the skin not in contact with the airbag can be ventilated and rested. After the rotating cylinder 2 drives the airbag tube 3 to rotate, the cylindrical airbag 4 changes the contact position with the patient's skin, so as to achieve the effect of preventing pressure sores and ventilation.
[0023] An inflation port 5 is provided on the outer wall of the airbag tube 3. The inflation port 5 is a valve core structure. The inflation port 5 can be connected to the inflation device 6 to inflate the cylindrical airbag 4. Pulling out the inflation device 6 can prevent the gas leakage in the cylindrical airbag 4. Pulling out the valve core can deflate the cylindrical airbag 4. This type of inflation port 5 is a common prior art and its details are not repeated here. One end of the inflation port 5 passes through the outer wall of the airbag tube 3 and is connected with the cylindrical airbag 4, thereby achieving the effect of inflation and deflation through the inflation port 5. The inflation device 6 can be an electric air pump or a manual air pump.
[0024] A skin-friendly pad 10 is arranged on the inner wall of the fixed cylinder 1 and the rotating cylinder 2. The inner liner of the skin-friendly pad 10 is filled with soft material and the surface is made of anti-allergic fabric, which improves the wearing comfort of the patient and avoids allergies.
[0025] A fixing ring 7 is fixedly connected to the fixing tube 1, and a buckle 8 is provided at one end of the restraint belt 9. The buckle 8 is detachably connected to the fixing ring 7, and the other end of the restraint belt 9 is connected to a fixed object, such as a bed frame, a column, etc. The restraint effect on the patient is achieved by connecting the restraint belt 9 to the fixing tube 1.
[0026] Specific usage:
[0027] The patient's limbs (such as arms) are passed through the fixed tube 1, the rotating tube 2 and the airbag tube 3 in sequence, and the inflation port 5 is inflated using the inflation device 6 to expand the cylindrical airbag 4 and fix the patient's limbs in the airbag tube 3.
[0028] One end of the restraint belt 9 is fixed to a fixed object such as a bed frame, and the snap buckle 8 at the other end of the restraint belt 9 is connected to the fixing ring 7 on the fixing tube 1, thereby achieving the effect of restraining the patient's limbs and the fixed object.
[0029] After restraining for a period of time, the rotating cylinder 2 can be manually rotated to drive the airbag cylinder 3 to rotate, thereby changing the contact position between the cylindrical airbag 4 and the skin of the patient's limbs to avoid pressure sores.
[0030] Pull out the valve core to release the gas in the cylindrical airbag 4 and release the restraint.
[0031] This embodiment needs to be cleaned and disinfected before and after use to meet medical standards.
[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
