Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a multifunctional bed used for traction of patients after spinal deformity release surgery. Background Art

[0002] Scoliosis deformity bone traction is to drive steel nails into the patient's head, pelvis or lower limbs, and use gravity or the power of a weight to perform traction. This type of traction is generally suitable for severe rigid scoliosis of more than 100 degrees, and can effectively loosen the deformity. Traction can also be used to test whether there is a reaction to nerve damage (leg pain, numbness, etc.) after spinal correction.

[0003] When treating patients with severe scoliosis, simple instrumental surgery is no longer effective. Forced surgical correction will cause excessive tension on the spinal cord and may lead to paraplegia. Therefore, chronic traction is required through a cranio-pelvic traction device to gradually straighten the spine before other spinal correction surgeries are performed to increase the safety of the operation. Usually, a traction bed is introduced during the traction process, and the patient's head and neck are connected to the bedside traction device respectively to achieve a traction effect. However, during the traction process, since the patient maintains a posture for a long time, the body is prone to stiffness, which makes the patient very uncomfortable. In addition, it is difficult for bedridden patients to turn over. Therefore, due to long-term pressure on local tissues, patients will suffer from persistent ischemia, hypoxia, and malnutrition, leading to tissue ulcers and necrosis, thereby forming pressure injuries or causing blood clots.

[0004] So in summary, there is an urgent need for a multifunctional bed for traction of patients after spinal deformity release surgery, which is easy to operate, simple to use, can ensure the traction of patients with scoliosis, improve the comfort of patients during traction, and relieve the stiffness of patients' local compressed muscles.

[0045] The device mainly provides a comfortable bed for patients who undergo traction after spinal deformity release surgery, thereby improving the comfort of patients and reducing the occurrence of pressure sores and other problems caused by muscle stiffness and inability to relax during lying flat on a traditional bed; it also reduces the incidence of thrombosis caused by long-term bed rest; it specifically provides a multifunctional bed for patients who undergo traction after spinal deformity release surgery; Figure 1 As shown, the traction multifunctional bed comprises a bed body 1, bed legs 2, and a bed head 3;

[0046] Wherein, traction braces are provided at both ends of the bedside; correspondingly, the traction braces include a head traction brace 4 and a leg traction brace 5; and the head traction brace 4 includes a head elastic traction belt 41 and a head fixation ring 42; and the leg traction brace 5 includes a leg elastic traction belt 51 and a leg fixation ring 52;

[0047] The head elastic traction belt 41 and the leg elastic traction belt 51 are movably connected to the bedside 3, and can be fixed to the bedside 3 by buckles, snaps and other devices. The bedside 3 in the device is generally a bedside with multiple cylindrical support rods, wherein the head elastic traction belt 41 and the leg elastic traction belt 51 can be movably fixed on the cylindrical support rods, and the distance between the head elastic traction belt 41 or the leg elastic traction belt 51 can also be adjusted as needed to achieve traction and fixation of the patient's head or legs, and the head elastic traction belt 41 and the leg elastic traction belt 51 in this embodiment have a certain elasticity and can be pulled appropriately;

[0048] Correspondingly, a plurality of threaded holes 53 are provided on the head fixing ring 42 and the leg fixing ring 52 , and when fixing the patient's head and legs, screws can be inserted through the threaded holes 53 to achieve fixation.

[0049] In addition, see Figure 2 and Figure 3 In order to reduce the stiffness of the patient's body caused by lying in bed for a long time, an air cushion is laid on the upper surface of the bed, wherein a plurality of groups of air bag units which are independent of each other and arranged in a matrix are arranged on the air cushion.

[0050] Correspondingly, the airbag unit 61 is composed of a plurality of airbags 62, and an air valve 63 is arranged on the airbag 62. A control module 64 is also arranged inside the airbag 62. The control module 64 also includes a controller 65, a pressure sensor 66 and a timer 67 which are electrically connected to each other.

[0051] The pressure sensor 66 is used to measure the pressure applied to the air mattress and transmit it to the controller 65; the controller 65 determines the value read by the pressure sensor 66, and then starts the timer 67 according to the read value, so as to realize the inflation and deflation of the air valve 63; and each air bag 62 is connected to an inflation branch pipe 68, and the inflation branches on the same air bag group are connected to the same inflation pipe 69, and the inflation pipe 69 is provided with an air source device 70;

[0052] Among them, the air source device 70 includes a main controller 71 and an air pump system 72; when the pressure sensor 66 on the air cushion bed senses the pressure in the airbag and converts it into a signal to feed back to the controller 65, the main controller 71 issues instructions according to the set program, and controls the air inlet and outlet of the air valve 63 by controlling the opening and closing of the air valve, so that the airbag units at different matrix positions can meet the pressure support requirements of a single point in the matrix, so that the contact surface between the air cushion and the patient presents a specific support surface according to the needs of the situation; preferably, the airbags on the airbag units are independent of each other and are combined in a matrix.

[0053] The specific control process is as follows: when inflating, according to the disease requirements, the program sets the pressure of the airbags arranged in the matrix to A. At this time point T1, the pressure sensor 66 detects that the pressure of the airbag is A1. If the value read by the pressure sensor 66 is lower than the pressure setting value A, the timer is started. If the time recorded by the timer 67 exceeds the time setting value T1, the controller 7 starts the air valve and inflates and pressurizes the airbag until the pressure inside the airbag is higher than the pressure setting value A; when deflation: according to the disease requirements, the program sets the pressure of the airbags arranged in the matrix to P. At this time point T1, the pressure sensor 66 detects that the pressure of the airbag is 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 sends an instruction to the exhaust valve according to the set program to control the exhaust valve to open and deflate the airbag unit. When the pressure inside the airbag unit reaches P, the exhaust valve is closed and the airbag unit stops deflation. This time point is t2.

[0054] Please see attached Figure 4 As shown, in this embodiment, the airbags 62 on the airbag unit 61 are preferably independent of each other and arranged in a horizontal direction, and the multiple airbags 62 are combined in a matrix, and the shape of the airbags 62 can be an elliptical or rectangular structure. The inflation branch 68 controls each individual airbag 62, so that the airbags can present different heights, and the appropriate height can be adjusted according to different pressures. The specific operation is as follows: Due to different airbag positions, different pressure requirements and different time points, different patient contact surface modes are combined; Figure 5 As shown in the modes 1, 2, 3, and 4 in the figure, modes 1 and 2 indicate that the air cushion bed body presses the patient contact surface at different time points or prevents the occurrence of bedsores through different contact surfaces; mode 3 (if the patient has bedsores) can indicate that the bedsore area is vacated, so that the bedsore area of ​​the patient will not be subjected to pressure, thereby achieving the purpose of treatment; (when in bedsore state) mode 4 indicates that the best contact surface is adjusted as needed according to the patient's body position and the size of the bedsore, so that the patient can be properly supported while lying in bed for a long time. The matrix combination of the airbag unit 61 of the utility model can also set a variety of different treatment modes according to specific usage conditions. Each mode can be defined in terms of position, pressure and time point according to the patient's needs, so that the contact surface between the mattress and the patient presents different contact surfaces at different times, and the airbag unit can be used at a specific time (such as before going to bed at night) to perform peristaltic massage on specific parts of the patient through the up and down peristalsis of the airbag unit, guide the patient to turn over regularly, prevent the patient from having poor blood circulation caused by lying in bed for a long time, increase the patient's treatment effect, prevent and treat bedsores, reduce the burden of medical care, and save medical expenses.

[0055] In this embodiment, the master controller 71 is preferably electrically connected to the controller 65 in each airbag 62, so as to simultaneously control the inflation or deflation of multiple airbags 62. The master controller 71 can perform timing and constant pressure control on the 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, and meets the patient's need to prevent bedsores according to the condition.

[0056] In this example, it is preferred to further include a mute unit 73 for eliminating noise during the use of the medical air mattress, and the mute unit 73 is electrically connected to the air source device 70. The mute unit 73 in the device can reduce the noise during the use of the air mattress, so that the patient feels more comfortable; the mute unit is electrically connected to the air source device, and the mute unit can be started at the same time when the main controller and the air pump system are started, which is more convenient to use.

[0057] like Figure 7 As shown, correspondingly, two connecting plates 11 are symmetrically fixedly installed on two outer walls away from each other of the bed body 1, and one of the bed heads 3 is rotatably installed between the two connecting plates 11 relative to the inner wall; wherein the bed head 3 is rotatably connected to the bed body 1. Specifically:

[0058] A rotating shaft 14 is symmetrically fixedly installed on the head of the bed 3 and at positions corresponding to the two connecting plates, and the rotating shaft 14 is rotatably connected to the corresponding connecting plates 11; when the patient needs to sit in a semi-supine position, the patient's head end can be moved to the head of the bed with the rotating shaft end, and the head of the bed 3 can be rotated with the bed body by manually adjusting it upwards, and adjusted to a certain height according to traction needs, thereby improving the patient's comfort and meeting the clinical patient's use; at the same time, when the adjustable head of the bed is used as a footrest, it can also be adjusted up and down appropriately according to needs, so as to achieve appropriate up and down activities of the patient's leg joints to reduce the incidence of thrombosis.

[0059] In order to facilitate the fixation of the headboard 3 after upward rotation, a fixing ear A12 is provided on the connecting plate 11; correspondingly, a plurality of fixing ears B13 are evenly provided on the headboard 3, wherein the fixing ears A12 and the fixing ears B13 are provided with telescopic hanging ears 15; therefore, the headboard can be fixed after rotation through the telescopic hanging ears 15.

[0060] In this embodiment, the telescopic hanging ear 15 is in an S-shaped structure, wherein the two ends of the telescopic hanging ear 15 are respectively hung on the fixed ear A12 and the fixed ear B13. Correspondingly, the fixed ear A12 and the fixed ear B13 are in a truncated cone structure, and an annular groove 16 for accommodating the telescopic hanging ear 15 is provided on the fixed ear A12 and the fixed ear B13; correspondingly, the two ends of the telescopic hanging ear 15 are respectively located in the annular groove 16 of the telescopic hanging ear 15.

[0061] The method for using the traction device and the bed body in the utility model is as follows: the patient lies flat on the bed body with an air cushion, and the corresponding parts of the patient are fixed by using the head traction brace and the leg traction brace on the bed head, and the threaded holes provided on the head fixing ring and the leg fixing ring are used to match the insertion of screws, so as to achieve fixation; one of the bed heads can be adjusted according to the actual needs of the patient, and the fixed ears and the telescopic hanging ears that cooperate with each other on the bed head and the bed body can be operated to achieve different height adjustments to match the daily use of the patient (such as eating, semi-supine state, etc.), thereby improving the comfort of the patient.

[0062] Among them, the telescopic principle of the "telescopic ear" in this embodiment is mainly realized by the structure of the sleeve and the latch. It is relatively common in the prior art, such as "fishing rod", "photography tripod", "selfie stick" and "travel stick", etc., and will not be elaborated here.

[0063] The method for using the air cushion in the utility model is as follows: during use, the patient lies flat on the air cushion bed body. When the patient needs to achieve a massage effect, the medical staff sets the instruction on the main controller, and the main controller sends a control signal, the air pump system and the silent unit are started at the same time, and the air bags on the air bag units are inflated and exhausted at intervals, and the time interval is set. The main controller controls the air bags to slowly and evenly pump air from left to right, and repeats the cycle until the preset time is reached, and the air pump system stops inflating or pumping air; at the same time, the inflation and exhaust degrees of each chamber can be controlled to achieve massages of different amplitudes; because each air bag is respectively connected to an inflation branch pipe, the pressure position of the air bag can be better controlled separately, so that the patient lies stably on the air cushion bed, and the patient is prevented from sliding sideways during the massage process; if a flipping effect is needed, the patient lies flat on the air cushion bed, and the main controller is operated to set the program. The main controller sends a control signal, and the air pump fills the air bags on the entire air bag unit with air, and controls the air pressure in the overall air bags on the air bag units on the left and right sides, thereby achieving different flipping amplitudes.

[0064] It should be noted that the utility model is easy to operate and simple to use, and can achieve the purpose of postoperative or preoperative correction and traction for patients with spinal deformity; at the same time, the airbag device provided can also collect the pressure borne by each airbag of the bed in real time, and integrate and analyze the data, and deflate and release the pressure of the airbags that are under too much pressure for more than a certain period of time, and inflate and pressurize the airbags that are under too little pressure for more than a certain period of time, so as to prevent uneven weight distribution among body parts, and can effectively prevent the occurrence of pressure sores from the root; and the matrix combination of airbag units in the utility model can set a variety of different treatment modes according to specific usage conditions, and each mode can be defined in terms of site, pressure and time point according to patient needs, so that the contact surface between the mattress and the patient is different at different times. Different contact surfaces are presented at different times, and the up and down peristaltic movement of the airbag unit can be used to perform peristaltic massage on specific parts of the patient at specific times (such as before going to bed at night), thereby guiding the patient to turn over regularly and preventing the patient from having poor blood circulation due to long-term bed rest, thereby increasing the treatment effect of the patient, preventing bedsores, reducing the burden on medical care, and saving medical expenses; and each airbag described in the utility model is controlled by a separate inflation branch pipe, which can flexibly adjust the air pressure of various parts of the air mattress, has the function of maintaining blood circulation in the patient's body and preventing bedsores, and also improves the comfort of the patient; and the airbag device described in the device is based on a new type of air mattress for rehabilitation and prevention of bedsores in patent publication number "CN207323638U", and its pneumatic principle can refer to the patent.
