Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a skeletal traction correction device for spinal deformities. Background Technology

[0002] Scoliosis, commonly known as scoliosis, is a three-dimensional deformity of the spine, including abnormalities in the coronal, sagittal, and axial planes. Severe scoliosis can affect a person's daily life, deform the body, affect cardiopulmonary function, and even involve the spinal cord, potentially causing paralysis. In the treatment of patients with severe scoliosis, simple mechanical surgery is often ineffective. Forced surgical correction can cause excessive tension on the spinal cord, potentially leading to paraplegia. Therefore, chronic traction using a craniopelvic traction device is necessary to gradually straighten the spine before performing other spinal correction surgeries, increasing the safety of the procedure.

[0003] Furthermore, a common method used in previous treatments was to fix a ring around the patient's skull and pelvis (see the attached diagram in the instruction manual). Figure 10 As shown in the diagram, support rods are added between the rings to achieve chronic traction on the spine of patients with severe scoliosis. However, when patients wear the traction device to rest, they often have to use thick foam padding on the bed or lean against a chair, making rest inconvenient. This traction is also quite painful for patients, often affecting their sleep at night, and carries the risk of skin infection around the steel pins. Furthermore, the patient's body is in a state of tension throughout the traction process, and maintaining one posture for a long time can easily lead to muscle strain. Therefore, while ensuring the traction support of the pelvic structure, the device should allow patients to sleep comfortably while wearing it.

[0004] Chinese patent application CN208693555U discloses a multifunctional orthopedic traction bed for medical use, including a bed board. A movable bed board is located at the upper left end of the bed board, and a fixed bed board is located at the right end of the movable bed board. The movable and fixed bed boards are connected by a rotating device. A traction bed board is located on the right side of the fixed bed board, and its lower end is mounted on the upper side of the bed board via a slide rail. A control panel is located on the right end of the bed board, and a hydraulic cylinder is located between the control panel and the traction bed board. This device combines cervical and leg traction, allowing patients to receive simultaneous cervical and leg traction on the traction bed. It offers good traction effect, high efficiency, and ease of operation. During prolonged traction treatment, patients can lift their upper body, effectively reducing fatigue and facilitating movement. It also includes a companion bed, allowing caregivers to rest without occupying ward space. However, this device only meets the needs of some ordinary traction patients and cannot be used by patients with severe scoliosis.

[0005] Therefore, there is an urgent need for a spinal deformity bone traction correction device that can meet the daily lying and resting needs of patients with severe scoliosis, and also provide back muscle massage during long-term lying to reduce muscle strain and pressure sores. However, there is no report on a spinal deformity bone traction correction device. SUMMARY

[0035] This device primarily addresses the issues faced by patients with spinal deformities undergoing skeletal traction, such as the tension in their bodies during traction, the prolonged maintenance of a single posture leading to muscle strain, and the inability to rest properly while wearing the traction device. To resolve these problems, a spinal deformity skeletal traction correction device is designed to assist patients in resting and falling asleep, reducing muscle strain during traction. Specifically, it is a resting bed suitable for correcting spinal deformities undergoing skeletal traction. This bed mainly includes a bed frame 1, a headboard 2, and bed legs 3. An air mattress 4 is laid on the upper surface of the bed frame 1. The air mattress 4 has several sets of independent, matrix-arranged airbag units 41. Each airbag unit 41 consists of several airbags 42, and each airbag 42 is equipped with an air valve 43. A control module 44 is also located inside each airbag 42. The control module 44 includes an electrically connected controller 45, a pressure sensor 44, and a timer 47. The pressure sensor 46 is used to measure… The pressure applied to the air mattress is transmitted to the controller 45. The controller 45 judges the value read by the pressure sensor 46 and then starts the timer 47 according to the read value, thereby realizing the inflation and deflation of the air valve 43. Each airbag 42 is connected to an inflation branch tube 48, and the inflation branch tubes of the same group of airbags are connected to the same inflation tube 49. The inflation tube 49 is equipped with an air source device 50. The air source device 50 includes a main controller 71 and an air pump system 72. When the pressure sensor 44 on the air mattress senses the pressure in the airbag and converts it into a signal to be fed back to the controller 45, the main controller 71 issues an instruction according to the set program, controls the opening and closing of the air valve 43 to control the air intake and exhaust volume of the air valve, so that the airbag units in different matrix positions meet the pressure support requirements of a single point in the matrix, and the contact surface between the air mattress and the patient presents a specific support surface as needed. Preferably, the airbags on the airbag units are independent of each other and arranged in a matrix.

[0036] The specific control process is as follows: When inflating, according to the disease requirements, the program sets the pressure of the matrix-arranged airbags to A. At this time point T1, the pressure sensor 44 detects the pressure of the airbag as A1. If the value read by the pressure sensor 46 is lower than the pressure setting value A, the timer is started. If the timer 47 records a time exceeding the time setting value T1, the controller 45 starts the air valve, inflating and pressurizing until the pressure inside the airbag is higher than the pressure setting value A. When deflating: According to the disease requirements, the program sets the pressure of the matrix-arranged airbags to P. At this time point T1, the pressure sensor 44 detects the pressure of the airbag as P2. If P2>P, the pressure sensor converts the sensed pressure P2 value into an electrical signal and feeds it back to the main controller 71. The main controller 71 issues an instruction to the air valve according to the set program, controlling the air valve to open and deflate the airbag unit. When the pressure inside the airbag unit reaches P, the air valve closes, and the airbag unit stops deflating. This time point is t2.

[0037] Please see the appendix Figure 4 As shown, in this embodiment, preferably, the airbags 42 on the airbag unit 41 are independent of each other and arranged laterally, and multiple airbags 42 are combined in a matrix. The shape of the airbags 42 can be elliptical or rectangular. The inflation tube 48 controls each individual airbag 42, allowing the airbag to present different heights. The height can be adjusted appropriately according to different pressure levels. Specifically, because different airbag positions, different pressure requirements, and different time points combine to form different patient contact surface patterns, such as... Figure 5 As shown in modes 1, 2, 3, and 4, modes 1 and 2 indicate that the air mattress presses on the patient's contact surface at different times or prevents pressure sores by using different contact surfaces; mode 3 (if pressure sores occur) indicates that the pressure sore area is vacated so that the patient's pressure sore area is not under pressure, thereby achieving the therapeutic purpose; mode 4 indicates that the optimal contact surface is adjusted according to the patient's position and the size of the pressure sore as needed, so that the patient can receive appropriate support while lying in bed for a long time. The matrix combination of airbag units 41 of the present invention can also be set with a variety of different treatment modes according to specific usage. Each mode can be defined at the point of contact, pressure, and time according to the patient's needs, so that the contact surface between the mattress and the patient presents different contact surfaces at different times. Moreover, at a specific time (such as before going to sleep at night), the up and down peristaltic movement of the airbag units can perform peristaltic massage on specific parts of the patient, prevent poor blood circulation caused by prolonged bed rest, increase the patient's treatment effect, prevent and treat pressure sores, reduce the burden on medical staff, and save medical expenses.

[0038] In this embodiment, preferably, the main controller 71 and the controller 45 in each airbag 42 are electrically connected to simultaneously control the inflation or deflation of multiple airbags 42. The main controller 71 can perform timed and pressure-controlled air pressure in the airbags at different matrix positions according to a set program, and control the air pressure in the air pump system so that the air mattress presents a specific support surface at a specific time point. Depending on the patient's condition, it can perform percussion massage on the cervical spine, lumbar spine, legs, wrist joints, etc., reducing muscle stiffness and improving patient comfort.

[0039] In this example, the device preferably also includes a noise reduction unit 73 for eliminating noise during the use of the medical air mattress, the noise reduction unit 73 being electrically connected to the air source device 70. The noise reduction unit 73 reduces noise during the use of the air mattress, making the patient more comfortable; the electrical connection between the noise reduction unit and the air source device allows the noise reduction unit to be activated simultaneously with the start of the main controller and the air pump system, making it more convenient to use.

[0040] A safety placement plate 5 is also provided on the air cushion 4. The safety placement plate 5 is further provided with a head ring fixing placement groove 51 and a pelvic ring fixing placement groove 52. Preferably, the head ring fixing placement groove 51 and the pelvic ring fixing placement groove 52 are both I-shaped structures, which include a horizontal groove 53 and a vertical groove 54. The horizontal groove 53 and the vertical groove 54 are arranged vertically, and the depth of the horizontal groove is greater than the depth of the vertical groove. When the patient lies flat on the bed, the head fixing ring fixed on his head can be placed in the corresponding head ring fixing placement groove. The cranial fixation ring is much higher than the fixation rings on both sides of the head, so the depth of the transverse groove can accommodate the use of the fixation ring at the bottom of the patient's head, allowing the patient with the head fixation ring to be fixed in the cranial ring fixation groove. Similarly, the corresponding pelvic ring fixation groove can also accommodate the pelvic fixation ring fixed at the patient's pelvis. This design facilitates the patient's ability to lie flat on the bed and rest, reduces the pressure and pain from the cranial and pelvic fixation rings on the patient's head and pelvis, improves the comfort of patients with scoliosis, and helps the patient fall asleep.

[0041] In this embodiment, preferably, a traditional Chinese medicine (TCM) placement pocket 55 is also provided on one side of the cranial ring fixing placement groove 51 and the pelvic ring fixing placement groove 52, and the TCM placement pocket 55 is provided with several ventilation holes 56. A Velcro closure 57 for controlling the opening and closing of the TCM placement pocket 55 is also provided on one side of the TCM placement pocket 55. The TCM placement pocket 55 can hold a TCM poultice for relieving spinal pain and assisting in treatment, thereby assisting the patient's treatment and reducing the patient's pain. During use, it can be opened and closed through the Velcro closure, and the ventilation holes allow the medicinal vapor to seep out. The TCM placement pocket can be placed on the patient's neck and lumbar spine, thereby achieving targeted treatment assistance.

[0042] Shock-absorbing casters 6 are also fixedly installed under the bed legs 3. Preferably, the shock-absorbing casters 61 are located at the four corners of the bed legs 2, and a foot-operated braking device 62 is also provided on the shock-absorbing casters 61. The braking device 62 is designed to facilitate operation by medical staff, conforms to the principle of saving effort, and is easy to fix and move. At the same time, the braking device is also provided with anti-slip texture 63, which increases the contact area between the medical staff's feet and the braking device, preventing side slippage when stepping on it and causing unnecessary damage, thereby increasing the stability and safety of the device.

[0043] The method of using the air cushion in this invention is as follows: During use, the patient lies flat on the bed, and the corresponding head fixation ring and pelvic fixation ring are placed in their respective head ring fixing slots and pelvic ring fixing slots. Then, when the patient needs a massage, the medical staff sets the instructions on the main controller, which sends a control signal. The air pump system and the silent unit start simultaneously, inflating and deflating the airbags on several airbag units at intervals. The main controller controls the airbags to slowly and evenly deflate and deflate from left to right at set time intervals, repeating the cycle until the preset time is reached, at which point the air pump system stops inflating or deflating. Simultaneously, the inflation and deflation levels of each chamber can be controlled to achieve different massage amplitudes. Because each airbag is connected to an inflation branch tube, the pressure position of the airbag can be better controlled individually, allowing the patient to lie stably on the air cushion bed and avoiding unnecessary harm to the patient due to excessive pressure during the massage, thus improving patient safety.

[0044] It should be noted that this invention is convenient to operate and simple to use, enabling patients with spinal deformities to rest and fall asleep before or after surgery. Simultaneously, the airbag device can collect real-time pressure data on each airbag in the bed, integrate and analyze the data, depressurize airbags that are under excessive pressure for a certain period, and inflate airbags that are under insufficient pressure for a certain period, preventing uneven weight distribution and effectively preventing pressure sores. Furthermore, the matrix combination of airbag units in this invention can be configured with various treatment modes according to specific usage conditions. Each mode can be defined according to the patient's needs in terms of location, pressure, and time, ensuring that the contact surface between the mattress and the patient is adjusted at different times. The device features different contact surfaces and can perform peristaltic massage on specific areas of the patient through the up-and-down movement of the airbag units at specific times (such as before bedtime). This prevents poor blood circulation and muscle stiffness caused by prolonged bed rest, increases the effectiveness of treatment, prevents pressure sores, reduces the burden on medical staff, and saves medical expenses. Furthermore, each airbag in this invention is controlled by an individual inflation branch tube, which can flexibly adjust the air pressure in different parts of the air mattress, maintaining blood circulation in the patient's body, preventing pressure sores, and improving patient comfort. The airbag device described in this invention is based on a novel rehabilitation and pressure sore prevention air mattress in patent publication number "CN207323638U", and its pneumatic principle can be referred to that patent.

[0045] Example 2

[0046] Please see the appendix Figure 8 Appendix Figure 9 As shown, attached Figure 8 This is a schematic diagram of the skeletal traction correction device for spinal deformity described in Embodiment 2. Figure 9This is a cross-sectional schematic diagram of the slide block and slide groove on the safety placement plate described in Embodiment 2.

[0047] The resting bed described in this embodiment is basically the same as the spinal deformity skeletal traction correction device in Embodiment 1. The only difference is that the safety placement plate 5 can be detachably fixed to the air cushion. Specifically, a groove 81 is provided on the air cushion corresponding to the safety placement plate, and a slide rail groove 82 is provided in the groove 81. The bottom of the safety placement plate 5 is provided with a slide rail block 83 that matches the slide rail groove, and the safety placement plate is slidably installed on the slide rail groove 81 in the groove of the air cushion. This setting allows the size of the safety placement plate to be changed and moved appropriately according to the height needs of different patients. For example, for shorter / taller patients, the safety placement plate at the head and pelvis can be moved relatively to meet the clinical needs of different patients.

[0048] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and additions without departing from the principle of the present invention, and these improvements and additions should also be considered within the scope of protection of the present invention.
