Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an adjustable thoracolumbar pillow. Background Art

[0002] Thoracolumbar pillows play a vital role in the rehabilitation care of patients with thoracolumbar fractures. Traditional thoracolumbar pillows have many limitations. First, in terms of height adjustment, most traditional pillows are fixed in height and cannot be flexibly adjusted according to the severity of the patient's fracture and individual differences. This makes it difficult for patients to obtain the most suitable support height during use, which may aggravate pain and affect the recovery of the fracture site. For example, for patients with more serious fractures, a higher pillow height is required to provide sufficient support to promote reduction and healing of the fracture site. For patients with milder fractures, excessively high pillow height will cause discomfort.

[0003] Secondly, in terms of length adjustment, traditional pillows also lack an effective adjustment mechanism; the locations of thoracolumbar fractures are different, and fractures may occur from T1 to L5 to S1, and traditional pillows cannot accurately locate the fracture site for support; for patients with thoracic fractures, the pillow cannot be adjusted to a suitable position to focus on supporting the thoracic spine, so that patients cannot receive targeted care during the rehabilitation process, so an adjustable thoracolumbar pillow is proposed to solve the above-mentioned problems.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-7 An adjustable thoracolumbar pillow comprises a pillow 1, the outer surface of the pillow 1 is covered with a pillowcase 2, the sides of the pillow 1 are respectively provided with a wire insertion hole 3 and a charging port 4, the interior of the pillow 1 is provided with a height adjustment component 5 and a length adjustment component 6, and the gap between the pillow 1 and the pillowcase 2 is filled with a high-density sponge 7.

[0032] Specifically, in the rehabilitation care of patients with thoracolumbar fractures, the thoracolumbar pillow plays a vital role; and the thoracolumbar pillow is composed of the above-arranged pillow 1, pillowcase 2, wire plug hole 3, charging port 4, height adjustment component 5, length adjustment component 6 and high-density sponge 7.

[0033] A zipper and a pull ring are arranged on one side of the pillowcase 2, and the pillowcase 2 is made of elastic and breathable fabric.

[0034] Specifically, the pillow 1 serves as the core supporting structure of the entire pillow, carrying the height adjustment component 5 and the length adjustment component 6, providing a basic framework for the entire pillow 1 and ensuring the installation and stable operation of various components; the pillowcase 2 is on the outer surface of the pillow 1, on the one hand, it plays a role in protecting the pillow body and preventing the internal components from external pollution and wear; on the other hand, the pillowcase 2 is made of elastic and breathable fabric, which can improve the comfort of patients when using it, and the zipper and pull ring arranged on one side are convenient for disassembly and cleaning.

[0035] The length adjustment component 6 includes a mounting plate 601 fixedly installed on the inner bottom wall of the pillow 1, and pushing blocks 602 are slidably installed inside the pillow 1 and on the left and right sides of the mounting plate 601. A driving motor 603 is fixedly installed on the surface of the mounting plate 601, and a bidirectional threaded rod 604 is fixedly installed on the output shaft of the driving motor 603. The outer surface of the bidirectional threaded rod 604 is threadedly connected to two bidirectional threaded blocks 605, and connecting plates 606 are fixedly installed on the opposite sides of the two pushing blocks 602. Two rotating shafts 607 are rotatably installed inside the pillow 1, and cross rods 608 are fixedly installed on the outer surfaces of the two rotating shafts 607.

[0036] Specifically, the driving motor 603 drives the bidirectional threaded rod 604 to rotate, so that the bidirectional threaded block 605 moves, and the pushing block 602 is pushed to slide in the pillow 1 through the cross rod 608 to achieve length adjustment. The fracture site can be accurately located from thoracic 1 to lumbar 5 sacral 1 for support, providing targeted care for patients; through the unique stretching design, it can be accurately located according to the fracture site; for patients with thoracic fractures, the pillow can be pulled forward to focus on supporting the thoracic spine; for patients with lumbar fractures, it can be adjusted to a suitable lumbar position to provide stable support for the fracture site.

[0037] The height adjustment component 5 includes a groove body 501 opened inside the pillow 1, and a main airbag 502 is fixedly installed inside the groove body 501, and a main pressure sensor 503 is fixedly installed on the surface of the main airbag 502. Two mounting grooves 504 are opened inside the two pushing blocks 602, and airbag 1 505 is fixedly installed inside one of the mounting grooves 504. An air pump 506 is fixedly installed on the inner bottom wall of the mounting groove 504 and at the bottom of the airbag 1 505. A main air pipe 507 is fixedly installed at the air outlet of the air pump 506, and four branch air pipes are fixedly installed at one end of the main air pipe 507. A main air relief valve 508 and a main pressure monitor 509 are fixedly installed on the surface of the main air pipe 507, and air relief valve 1, air relief valve 2, air relief valve 3 and air relief valve 4 are fixedly installed on the outer surfaces of the four branch air pipes, and pressure monitor 1, pressure monitor 2, pressure monitor 3 and pressure monitor 4 are fixedly installed on the outer surfaces of the four branch air pipes.

[0038] Specifically, the height of the pillow 1 is adjusted by inflating the main airbag 502 and each sub-airbag through the air pump 506 and controlling the deflation through the air release valve. The height adjustment is controlled between 8-10 cm and can be accurately adjusted according to the severity of the patient's fracture and body pressure feedback to provide just the right support for the injured part, relieve the patient's pain, and promote fracture recovery. If the height needs to be lowered, the control terminal controls the deflation of each airbag, and deflation is achieved by setting an air release valve on the inflation pipeline.

[0039] Specifically, after the patient lies on the pillow 1, the main pressure sensor 503 will judge the severity of the fracture based on the pressure of various parts of the body on the pillow 1 (the greater the pressure, the more serious the fracture may be). After the main pressure sensor 503 transmits the pressure data to the control terminal, the control terminal calculates the required inflation or deflation amount of each airbag according to a preset algorithm.

[0040] The space between the pillow 1 and the pillowcase 2 is filled with high-density sponge 7 .

[0041] Specifically, soft materials such as high-density sponge 7 are used inside the pillow 1 for the thoracic and lumbar vertebrae. The high-density sponge 7 can fit the body curve and disperse the pressure, thereby avoiding additional pressure on the injured thoracic and lumbar vertebrae and providing gentle care for the fracture site. The pillow 1 and the push block 602 are made of high-strength plastic to provide stable support force, prevent the pillow 1 from deforming, and ensure consistent support effect.

[0042] In summary, the adjustable thoracolumbar pillow, through the height adjustment component 5 and the length adjustment component 6, can achieve precise adjustment of the height between 8-10cm and the length from thoracic 1 to lumbar 5 sacral 1; the height adjustment can be based on the severity of the patient's fracture and body pressure feedback, and the inflation and deflation of the airbag can be precisely controlled by the inflation pump 506 and the deflation valve; the length adjustment is driven by the driving motor 603 to drive the bidirectional threaded rod 604, and the cross rod 608 to push the push block 602 to slide; this provides personalized support for patients with different fracture conditions, can effectively reduce pain, and promote fracture recovery.

[0043] In addition, the pillow 1 adopts a structure in which high-density sponge 7 is filled inside and high-strength supporting material is used outside. The high-density sponge 7 fits the body curve, disperses pressure, avoids additional pressure on the injured part, and improves comfort. The pillow 1 and the push block 602 are made of high-strength plastic to provide stable supporting force, prevent the pillow 1 from deforming, ensure consistent supporting effect, and provide reliable support for patients during the rehabilitation process.
