Cerebrospinal fluid leakage body position correction device

Abstract

The utility model relates to a cerebrospinal fluid leakage body position correcting device which comprises a positioning pad and an adjustable air bag. The positioning pad is used for being cushioned at the position above the waist of the lying-position patient so as to keep the relative position with the patient. The adjustable air bag is used for being cushioned at the leg position of the lying position patient so as to keep the leg height higher than the brain height. The positioning pad and the adjustable air bag are connected in a spaced mode. In the inflated state, the adjustable air bag comprises a first air bag in an inclined state and a second air bag in a plane state, a spacing space exists between the lower end of the first air bag and the positioning pad, and the lower end of the first air bag is higher than the positioning pad, so that the posture of the patient is in a head-low and foot-high state. The height of the positioning pad is not adjusted, so that the risk of wrong posture correction possibly caused by multi-selectivity control is reduced. According to the utility model, the legs instead of the head are adjusted, so that the head is prevented from being adjusted, and the oppression of the chest of a patient and even female breasts is reduced.

Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a cerebrospinal fluid leakage posture correction device. Background Art

[0002] Cerebrospinal fluid (CSF) is a colorless and transparent liquid present in the ventricles and subarachnoid space. When the cerebrospinal fluid cavity is connected to the outside world and cerebrospinal fluid leaks out, it is called cerebrospinal fluid leakage (CSFL). Cerebrospinal fluid leakage is one of the common complications after spinal surgery. It is caused by damage to the dura mater, which causes cerebrospinal fluid to leak out from the surgical incision or drainage tube. This complication often occurs due to damage to the dura mater and arachnoid mater during the surgical operation.

[0003] At present, the head-down-feet-high position is often used clinically to relieve the symptoms of low intracranial pressure in patients with cerebrospinal fluid leakage after thoracic and lumbar surgery. Some doctors will sew a deep stitch at the drainage tube opening after the patient removes the drainage tube and use a sandbag to apply pressure bandage, and then lie prone for 24 hours. However, the head-down-feet-high position will cause congestion in the head, increase the amount of blood returning to the heart, and increase the heart load; the prone position will compress the patient's face, chest cavity and even female breasts, affecting the patient's vision and breathing. Many patients cannot fully adapt to the change in body position, which in a sense increases the patient's discomfort and affects the quality of care for the patient; secondly, because the patient maintains the same body position for a long time, the risk of pressure injury will also increase.

[0004] There are generally two types of beds with posture correction (e.g., lying posture) in the prior art: first, the posture of the patient lying on the bed is changed by changing the shape of the bed itself; second, a mattress is added to the bed to adjust the patient's posture. Since the mattress can adapt to a variety of beds and is low in cost, when correcting the patient's posture, both patients and medical staff are more willing to use a mattress with a changeable shape to correct the patient's posture.

[0005] Regarding the airbag adjustment cushion that is most commonly used in the prior art, when adjusting the patient's prone position with the head low and the feet high, the patient's family members generally adopt the adjustment method of moving the feet up or lowering the head. The airbags in the prior art are set in an integrated manner, with the family members being able to choose the elevated part by themselves, or are set to cover the entire bed and the medical staff or the patient's family members being able to choose the adjustment area by themselves. The former setting method has the risk of causing the elevation device to be misplaced when the patient moves, causing the adjusted posture to shift and affecting the patient's recovery. The latter setting method has the risk of causing the patient's elevated area to be misplaced due to operational errors by the guardians of some patients.

[0006] Therefore, it is very important to correct the posture of patients with cerebrospinal fluid leakage in a special posture, which not only needs to meet the treatment plan requirements, but also needs to increase the comfort of patients. However, most of the existing technologies are auxiliary devices for fixing the patient's posture, and the structure is complex, which makes it inconvenient and inaccurate for medical staff or the patient's guardian to operate correctly. Therefore, the utility model proposes a posture correction device specifically suitable for patients with cerebrospinal fluid leakage, which can simultaneously meet the treatment needs and improve the comfort of patients.

[0007] The invention patent with application publication number CN107594998A discloses a multifunctional orthopedic mattress, which can more conveniently fix the patient's heel when performing calcaneal traction. The traction needle is arranged in the recess and is not easy to hit the mattress. The patient's heel can be observed more easily through a mirror. When a patient has cerebrospinal fluid leakage, the patient can be safely and easily placed in the required position by removing part of the mattress. The patent discloses a multifunctional orthopedic mattress, including a lower limb mattress and an upper limb mattress connected to the lower limb mattress. The lower limb mattress includes a lower limb bearing mattress and a filling pad arranged on the lower limb bearing mattress. The upper surface of the lower limb bearing mattress is provided with a groove, the groove extends outward to the end face of the lower limb bearing mattress, an outer opening is provided on the outer end of the groove, the width of the outer opening is greater than the distance between the two side walls of the groove, the filling pad is embedded in the groove, and a concave recess is provided on the outer end of the bottom surface of the groove. However, the defect of the patent is that the patient's head-low-foot-high position cannot be achieved by simply removing part of the mattress. The mattress also requires other supporting equipment to lift the patient's lower limbs in order to correct the patient's desired body position, and cannot achieve rapid adjustment of the patient's body position. In addition, the device cannot adjust the lifting height and angle of the patient's legs according to the patient's different body shapes, causing the patient to feel uncomfortable. The mattress is not suitable for meeting treatment needs and patient comfort needs.

[0008] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the inventor studied a large number of documents and patents when making the present utility model, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present utility model does not have the characteristics of these prior arts. On the contrary, the present utility model already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Utility Model Content

[0009] The existing technology mainly changes the lying posture of the patient by setting a medical bed device that can adjust the support state. For example, the patent document with publication number CN105287129A discloses a multifunctional medical bed, including a bed board, a bed frame, and wheels. The bed board includes a lying part, a backrest and a leg part that are rotatably connected to the front and rear sides of the lying part. The bed frame includes a lower bed frame and an upper bed frame. The upper bed frame can be raised and lowered on the lower bed frame along its own height direction. The wheels are located at the bottom of the lower bed frame. The medical bed also includes a first adjustment mechanism and a second adjustment mechanism for adjusting the lifting of one end of the backrest and the leg part, and a third adjustment mechanism for adjusting the lifting of the upper bed frame. The third adjustment mechanism includes two relatively independent lifting units installed on the front and rear sides of the bed frame. The two lifting units can synchronously or asynchronously drive the front and rear ends of the upper bed frame to rise or fall. By setting the third adjustment mechanism, the technical solution can enable the medical bed to achieve the tilting requirement of the patient's head being higher or lower than the feet, and at the same time ensure that no horizontal displacement occurs during the lifting process of the bed board. However, the medical bed in this technical solution can only adjust the support position of the patient's head and legs, and cannot adjust the pressure position according to the patient's actual surgical site; at the same time, there is no spacing space structure between the lying part and the backrest and leg support part in this technical solution that can allow the patient's lumbar drainage tube to pass through, which makes it impossible to be used for patients with a drainage tube on the waist.

[0010] In view of the shortcomings of the prior art, the technical solution of the utility model is to provide a cerebrospinal fluid leakage posture correction device, which includes a positioning pad and an adjustable airbag. The positioning pad is used to pad the position above the waist of a lying patient to maintain the relative position with the patient. The adjustable airbag is used to pad the leg position of the lying patient to keep the leg height higher than the brain height. The positioning pad and the adjustable airbag are connected in a manner of having a gap. The positioning pad and the adjustable airbag are connected in a manner of forming a gap space between the two to allow the patient's lumbar drainage tube to pass through. In the inflated state, the adjustable airbag includes a first airbag in an inclined state and a second airbag in a planar state, and there is a gap space between the lower end of the first airbag and the positioning pad, and the height of the lower end of the first airbag is greater than the height of the positioning pad, so that the patient's posture is in a head-down-feet-high position. When the adjustable airbag is inflated and the legs are raised, the patient's lumbar drainage tube passes through the gap space between the positioning pad and the adjustable airbag to avoid being compressed. Compared with the above-mentioned prior art, the positioning pad in the utility model can be used to contact with the patient and maintain the relative position between the two, and the adjustable airbag placed at the position of the patient's legs in a supine position can be adjusted in height so that the patient's legs are higher than the brain, and there is a spacing space between the positioning pad and the adjustable airbag to allow the patient's lumbar drainage tube to pass through. Based on the above-mentioned distinguishing technical features, the technical problems to be solved by the utility model may include: how to provide a drainage component setting space for the patient while adjusting the patient's supine position, so as to prevent the patient's supine position adjustment from interfering with the drainage process. Specifically, the positioning pad of the utility model does not adjust the height, reducing the risk of incorrect posture correction that may be caused by multiple selective control. The low intracranial pressure symptoms of patients with cerebrospinal fluid leakage can make the patient's head more sensitive. The utility model is set to adjust the legs instead of the head, which can reduce the pressure on the patient's chest and even the female breast while avoiding adjusting the head. A spacing space for placing the drainage tube is provided between the positioning pad and the adjustable airbag, thereby avoiding the pressure on the drainage tube during the correction of the patient's body position. Especially for patients with drainage tubes in their waist, the provision of this separation space is an important technical means.

[0011] According to a preferred embodiment, a telescopic belt with adjustable length is provided between the positioning pad and the adjustable airbag. The telescopic belt is used to limit the distance between the positioning pad and the adjustable airbag. The two ends of the telescopic belt are respectively connected to at least one side of the positioning pad and the adjustable airbag. Compared with the above-mentioned prior art, the positioning pad and the adjustable airbag in the utility model are connected by a telescopic belt provided therebetween. Based on the above-mentioned distinguishing technical features, the technical problems to be solved by the utility model may include: how to adjust the size of the interval space, and at the same time adjust the distance between the positioning pad and the adjustable airbag according to the adaptability of patients of different heights, so as to prevent the phenomenon that the positions of various parts of different patients do not match the positioning pad and the adjustable airbag when using the airbag. Specifically, the telescopic belt can be used to adjust and limit the size of the interval space, so as to avoid the positioning pad and the adjustable airbag being too far apart, so that the patient's body position is affected and changed.

[0012] According to a preferred embodiment, the retractable belt includes a first retractable belt connected between the positioning pad and the adjustable airbag on one side and a second retractable belt connected between the positioning pad and the adjustable airbag on the other side. The first retractable belt and the second retractable belt jointly define the position of the positioning pad to prevent the positioning pad from shifting. Medical staff can also choose to stretch the first retractable belt or the second retractable belt to form a smaller fan-shaped spacing space located on the patient's buttocks that is only used to accommodate the drainage tube, thereby avoiding the discomfort caused to the patient by the larger gap.

[0013] According to a preferred embodiment, the positioning pad includes a pressure piece. At least one strip airbag is arranged on the surface of the pressure piece in contact with the patient, and the strip airbag is arranged at one end of the positioning pad close to the adjustable airbag to apply pressure to the surgical wound. The strip airbag has a first length along the circumference of the patient's waist and a second length along the axial direction of the patient's waist. When the patient does not have a surgical wound and needs to be pressed, the strip airbag can be used to press the wound. When there is no surgical wound, the strip airbag can be used to support the patient's waist to avoid obvious discomfort in the waist due to the height difference.

[0014] According to a preferred embodiment, the positioning pad includes a fixing belt extending from at least one side of the positioning pad, the fixing belt is wrapped around the patient's waist and detachably attached to the other side of the positioning pad, and when the fixing belt is wrapped around the patient's waist, the pressure between the strip airbag and the patient increases. Compared with the above-mentioned prior art, the positioning pad in the utility model is provided with a pressurizing member capable of applying pressure to the postoperative wound of the lumbar spine of the patient's waist. Based on the above-mentioned distinguishing technical features, the technical problems to be solved by the utility model may include: how to pressurize and fix the wound after the drainage tube is removed to improve the pressurization and fixation effect of the patient's postoperative incision. Specifically, the position of the strip airbag corresponds to at least a part of the postoperative wound of the lumbar spine of the patient's waist, so as to pressurize the postoperative wound of the lumbar spine of the patient through the strip airbag. The pressurizing member corresponding to the patient's waist can be filled with gas to fix the patient on the positioning pad in the form of the expansion of the strip airbag, that is, the utility model fixes the patient and the positioning pad by the cooperation of the pressurizing member and the fixing belt, thereby avoiding the relative displacement of the patient and the positioning pad. Since the postoperative wound on the patient's lumbar spine needs to drain the blood congestion in the surgical wound, reduce the formation of hematoma in the wound, and avoid nerve compression. Therefore, the patient needs to undergo drainage observation for 1 to 7 days after lumbar spine surgery. After the drainage is completed, the healing of the wound can be promoted by applying pressure. Therefore, during the drainage stage of the patient, the utility model forms a spacing space for accommodating the drainage tube and corresponding to the postoperative wound on the patient's lumbar spine by stretching the retractable belt, thereby avoiding compression of the drainage tube. Not only that, after the patient's drainage is completed, the retractable belt can shrink so that the pressure piece corresponds to the postoperative wound on the patient's lumbar spine, thereby assisting the patient's healing by applying pressure to the patient's wound.

[0015] According to a preferred embodiment, the position of the strip airbag on the pressure piece is adjustable. The strip airbag is arranged on the pressure piece in an adhesive manner. The first length and / or the second length of the strip airbag are variable along the direction of the postoperative lumbar vertebrae wound of the patient's waist to cover the postoperative lumbar vertebrae wound of the patient's waist. The strip airbag can be tilted so that the direction of its first length and / or the second length conforms to the actual direction of the postoperative lumbar vertebrae wound of the patient's waist, thereby completely covering the postoperative lumbar vertebrae wound of the patient's waist.

[0016] According to a preferred embodiment, when the adjustable airbag is inflated, an inclined surface is provided at the top of the adjustable airbag. An inclined surface is provided at the top of the first airbag, and the lowest point height of the inclined surface is higher than the highest point height of the positioning pad. The side with a lower height of the inclined surface is adjacent to the positioning pad. The lowest point height of the inclined surface is higher than the highest point height of the positioning pad. The angle of the inclined surface of the utility model can be adjusted by the inflation amount of the adjustable airbag to meet the needs of patients with cerebrospinal fluid leakage in different regions and under different conditions, thereby achieving patient posture correction and facilitating patient recovery.

[0017] According to a preferred embodiment, the first airbag is connected to the second airbag but not connected, and the inclined surface of the first airbag is a plane formed of a non-soft material. The separation of the first airbag and the second airbag enables their respective inflation volumes to be independently controlled, thereby achieving adjustment of the height and angle of the inclined surface to meet different recovery time periods or different recovery needs of patients after surgery.

[0018] According to a preferred embodiment, a pleated structure is provided on a side of the second airbag away from the first airbag. The pleated structure includes a plurality of layers folded toward the inside of the second airbag. The plurality of layers divide the interior of the second airbag into a plurality of spaces. Adjacent layers are connected by through holes, so that when the second airbag is inflated, the height of the second airbag changes based on the amount of inflation. Moreover, when the second airbag is inflated, the second airbag forms an inclined angle. The pleated structure is, for example, a pleated structure, the interior of which is composed of a multi-layer structure, and each layer is connected by a through hole. Thus, when the pleated structure reaches a filled state, the second airbag behaves as an inclined airbag with an inclined angle, so as to achieve further angle adjustment of the inclined surface.

[0019] According to a preferred embodiment, a limiting structure for preventing the patient's legs from moving is provided on the inclined surface. The limiting structure is provided on the inclined surface in the form of a groove. The limiting structure can effectively limit the movement of the patient's legs, preventing the patient from falling from the inclined surface due to unconscious leg movement.

[0020] According to a preferred embodiment, the positioning pad is provided with a headrest having a head shape for placing the patient's head. The headrest is connected to the positioning pad in an adhesive manner so that the patient's face can be placed in the headrest. The height of the positioning pad close to the headrest is level with the height of the lowest point of the headrest. When using it, patients with cerebrospinal fluid leakage can place their heads in the headrest, and adjust the height of the legs through the adjustable airbag to achieve a head-low-feet-high position. The utility model position pad has the advantages of easy operation and economic applicability. It does not affect the patient's view of objects from above, and can well improve the comfort of the lying position of patients with cerebrospinal fluid leakage, meet treatment needs, and improve the quality of care. The patient's head is in a low position, while the height from the chest and waist to the legs increases. The slope change is set to avoid the formation of a "step" between the head and the high position that affects the patient's comfort, which solves the problem that existing patients with cerebrospinal fluid leakage need to maintain a special position for a long time.

[0021] According to a preferred embodiment, the positioning pad is also provided with a transverse structure for placing the patient's arm transversely. The transverse structure is rotatably connected to the main structure of the positioning pad located at the patient's waist. The transverse structure serves as a receiving component after the patient's arm is unfolded, and can be used to receive the patient's hand when the patient needs to receive an infusion.

DETAILED DESCRIPTION

[0029] The following is a detailed description with reference to the accompanying drawings.

[0030] Example 1

[0031] The present application relates to a cerebrospinal fluid leakage posture correction device, such as Figure 1 As shown, the device includes a positioning pad 100 and an adjustable airbag 200. The positioning pad 100 is used to pad the position above the waist of a lying patient to maintain the relative position with the patient. The adjustable airbag 200 is used to pad the leg position of a lying patient to keep the leg height higher than the brain height. The positioning pad 100 and the adjustable airbag 200 are connected in a manner of having a gap. The positioning pad 100 and the adjustable airbag 200 are connected in a manner of forming a spacing space 300 between the two to allow the patient's lumbar drainage tube to pass through. When the adjustable airbag 200 is inflated and the legs are raised, the patient's lumbar drainage tube passes through the spacing space 300 between the positioning pad 100 and the adjustable airbag 200 to avoid being compressed. The positioning pad 100 can be a rectangular, circular or other shaped body position pad placed under the patient, which is made of a flexible material. The positioning pad 100 of the utility model is arranged at the patient's waist to confirm whether the leg raising part has jumped.

[0032] According to a preferred embodiment, Figure 3 and Figure 4 As shown, a retractable belt 400 for changing the size of the interval space 300 is provided between the positioning pad 100 and the adjustable airbag 200. The retractable belt 400 is connected to at least one side of the positioning pad 100 and the adjustable airbag 200 in a manner of adjusting the distance between the positioning pad 100 and the adjustable airbag 200 by changing the length. Medical staff can form the interval space 300 by stretching the positioning pad 100 and the adjustable airbag 200. The retractable belt 400 can be used to limit the size of the interval space 300 to prevent the positioning pad 100 and the adjustable airbag 200 from being too far apart, so that the patient's body position is affected and changed.

[0033] According to a preferred embodiment, the retractable belt 400 includes a first retractable belt 401 connected between the positioning pad 100 and the adjustable airbag 200 on one side and a second retractable belt 402 connected between the positioning pad 100 and the adjustable airbag 200 on the other side. Figure 5 As shown, the first retractable belt 401 and the second retractable belt 402 jointly define a space 300 to accommodate the patient's lumbar drainage tube. When the patient needs lumbar drainage, the medical staff can separate the positioning pad 100 from the adjustable airbag 200 through the first retractable belt 401 and the second retractable belt 402, thereby leaving a space 300 that can accommodate the drainage tube, thereby avoiding the compression of the drainage tube during the process of correcting the patient's body position. Furthermore, the medical staff can choose to stretch the first retractable belt 401 or the second retractable belt 402 to form a smaller fan-shaped space 300 located on the patient's buttocks that is only used to accommodate the drainage tube, thereby avoiding the discomfort caused to the patient by the larger gap.

[0034] According to a preferred embodiment, Figure 2As shown, the positioning pad 100 includes a pressure piece 500. At least one strip airbag 501 is arranged on the surface of the pressure piece 500 in contact with the patient, and the strip airbag 501 has a first length along the circumference of the patient's waist and a second length along the axial direction of the patient's waist. The pressure piece 500 is used to maintain the relative position of the positioning pad 100 and the patient. The pressure piece 500 is a pasteable plate with a certain thickness. The pressure piece 500 is fixed on the positioning pad 100, which reduces the height difference between the positioning pad 100 and the first airbag 201 on the one hand, and also increases the pressure between the strip airbag 501 and the wound. For example, the pressure piece 500 is pasted on the positioning pad 100 by glue, or the pressure piece 500 is fixed on the positioning pad 100 by a fixing member such as a bolt. On the other hand, it can be used to paste the strip airbag 501. The strip airbag 501 and the pressure piece 500 are pasteable, so that the position of the strip airbag 501 can be adjusted according to the position of the wound. The strip-shaped airbag 501 may be an inflatable airbag or a capsule filled with elastic liquid material.

[0035] According to a preferred embodiment, the positioning pad 100 includes a fixing belt 103 extending from at least one side of the positioning pad 100. The fixing belt 103 is wrapped around the patient's waist and is detachably connected to the other side of the positioning pad 100 to fix the pressure member 500 on the patient's waist. The position of the strip airbag 501 corresponds to at least a portion of the postoperative lumbar vertebrae wound of the patient's waist, so that the strip airbag 501 can pressurize the postoperative lumbar vertebrae wound of the patient. When the patient is relatively fixed to the positioning pad 100 by the fixing belt 103, the uneven surface formed by the plurality of strip airbags 501 can also fix the patient to avoid relative displacement between the positioning pad 100 and the patient.

[0036] According to a preferred embodiment, the position of the strip airbag 501 on the pressure piece 500 is adjustable. The first length and / or the second length of the strip airbag 501 are variable along the direction of the postoperative wound on the patient's waist and lumbar spine to cover the postoperative wound on the patient's waist and lumbar spine. The contact surface between the strip airbag 501 and the pressure piece 500 can be changed in position by Velcro. Thus, the strip airbag 501 can be placed at the position of the pressure piece 500 corresponding to the postoperative wound on the patient's waist and lumbar spine. In addition, due to the setting of the Velcro, the first length and / or the second length of the strip airbag 501 do not need to be strictly set along the circumference or axial direction of the patient's waist, that is, the strip airbag 501 can be tilted so that the direction of its first length and / or the second length conforms to the actual direction of the postoperative wound on the patient's waist and lumbar spine, thereby completely covering the postoperative wound on the patient's waist and lumbar spine.

[0037] Furthermore, the strip airbag 501 is provided with a buckle or Velcro for limiting the volume of the strip airbag 501 after inflation, so that the first length and / or second length of the strip airbag 501 can be reduced by folding part of the outer surface of the strip airbag 501 into the strip airbag 501 and fixing it by the buckle or Velcro. For example, a snap button can be provided near the midpoint of one side of the first length direction of the strip airbag 501. Medical staff can achieve the effect of reducing the first length of the strip airbag 501 by folding the midpoint of the strip airbag 501 inward and fixing the folded shape by the snap button.

[0038] Since the patient's body position is head-down, there is a risk that the patient may be slightly displaced toward the head of the bed, which may cause the opening at the head of the bed that allows the patient to see to be misaligned with the patient's face. The non-planar setting of the strip airbag 501 can avoid the change caused by the positioning pad 100 moving from the patient's waist to the chest. In addition, when there is a relative displacement between the patient and the positioning pad 100, the height of the patient's legs may drop. Since the height of the legs is adjusted by medical staff, the drop in height may affect the patient's recovery. In addition, the positioning pad 100 of the utility model does not perform height adjustment, reducing the risk of incorrect posture correction that may be caused by multiple selective controls.

[0039] The low intracranial pressure symptoms of patients with cerebrospinal fluid leakage will make the patient's head more sensitive. The utility model adjusts the legs instead of the head, which can avoid adjusting the head and reduce the pressure on the patient's chest and even the female breast. According to the physiological characteristics of female patients, the utility model can completely raise the waist by arranging more strip air bags 501 at the waist, so that the female patient's chest is not squeezed, reducing the discomfort of the female patient's chest.

[0040] According to a preferred embodiment, when the adjustable airbag 200 is inflated, an inclined surface 210 is provided at the top of the adjustable airbag 200. The side of the inclined surface 210 with a lower height is adjacent to the positioning pad 100, so that the legs begin to rise. The angle of the inclined surface 210 of the utility model can be set to 15° to 30° to meet the needs of patients with cerebrospinal fluid leakage in different regions and under different conditions. The patient's body position can be quickly corrected by adjusting the inflation amount of the adjustable airbag 200, which is convenient for the patient to recover. The height difference between the highest position and the lowest position of the inclined surface 210 is preferably 20cm to 60cm. The horizontal length of the inclined surface 210 is preferably 80cm to 100cm.

[0041] According to a preferred embodiment, the adjustable airbag 200 includes a first airbag 201 for lifting the patient's legs and a second airbag 202 for increasing the inclination angle of the patient's legs. The first airbag 201 is not connected to the second airbag 202, and is inflated by a first air pump and a second air pump, respectively. The first airbag 201 is arranged on the side of the inclined surface 210 close to the positioning pad 100. The second airbag 202 is connected to the side of the first airbag 201 away from the positioning pad 100. In the utility model, the first airbag 201 and the second airbag 202 can be composed of sealing cloth and PVC material. The first airbag 201 and the second airbag 202 are respectively connected to different air pumps for inflation, thereby adjusting the inflation amount of the first airbag 201 and the second airbag 202 by adjusting the switch of the air pump, so as to adjust the height and angle of the inclined surface 210, and meet the different rehabilitation time periods or different rehabilitation needs of patients after surgery.

[0042] According to a preferred embodiment, the first airbag 201 is used to place the patient's thigh. The second airbag 202 is used to place the patient's calf. The connection between the first airbag 201 and the second airbag 202 corresponds to the knee where the patient's thigh and calf are connected. Therefore, the utility model can adjust the support height and angle of the patient's thigh and calf by controlling the difference in the amount of air filled into the first airbag 201 and the second airbag 202, thereby performing posture correction for patients of different body shapes.

[0043] According to a preferred embodiment, the side of the second airbag 202 away from the first airbag 201 is provided with a pleated structure 203 having an outer surface of the second airbag 202 folded to increase the inflation space on one side of the second airbag 202. When the second airbag 202 is inflated, the second airbag 202 raises the side with a higher height of the inclined surface 210. The interior of the pleated structure 203 is composed of a multi-layer structure, and each layer is connected by a through hole. Thus, when the pleated structure 203 reaches a full state, the second airbag 202 behaves as an inclined airbag with an inclined angle to achieve further angle adjustment of the inclined surface 210. Preferably, the angle of the inclined surface 210 can also be adjusted by adjusting the ratio of the inflation amount between the first airbag 201 and the second airbag 202. The design of the pleated structure 203 can increase the degree of angle change of the second airbag 202, improve the angle change range of the inclined surface 210, and avoid the large height difference between the first airbag 201 and the second airbag 202 due to the different inflation amounts. Moreover, the pleated structure 203 can be used to further adjust the patient's calf to avoid discomfort caused by the patient's leg not fitting with the inclined surface 210. Especially when the patient needs to stay in the prone position for a long time, the adjustment of the calf can relieve the patient's fatigue and ensure that the knee is raised.

[0044] Since patients who lie prone for a long time with their head down and feet high are restricted by their body position, their legs may be in great discomfort. If the inclined plane 210 with a single tilt angle is used, the patient's legs need to be straightened or the knees need to be against the inclined plane 210 while the head is down and the feet are high, so the patient cannot tolerate this body position for a long time. Therefore, the utility model adjusts the height and angle of the patient's thigh and calf respectively through the first airbag 201 and the second airbag 202, and the second airbag 202 has a pleated structure 203 that can form a different tilt angle from the first airbag 201, so that the patient's knee can be placed at the connection between the first airbag 201 and the second airbag 202, and the head down and feet high body position is still maintained.

[0045] According to a preferred embodiment, a limiting structure 211 for preventing the patient's legs from moving is provided on the inclined surface 210. The limiting structure 211 is provided on the inclined surface 210 in the form of a groove. Further, a groove matching the limiting structure 211 is provided on the first airbag 201 and the second airbag 202, so that the limiting structure 211 on the inclined surface 210 still exists during the subsequent inflation process. The limiting structure 211 can effectively limit the movement of the patient's legs and prevent them from falling from the inclined surface 210 due to the patient's unconscious leg movement.

[0046] According to a preferred embodiment, the positioning pad 100 is provided with a headrest 101 having a head shape for placing the patient's head. The headrest 101 can be used to prompt the patient's correct posture and prevent the user from setting the adjustable airbag 200 at the head position and raising the wrong position. It should be noted that since the patient is usually in a prone position, the headrest 101 is not necessarily used to accommodate the patient's head, and it can also be used as a patient support point for the patient to maintain a prone position on the bed. Preferably, the headrest 101 can move on the positioning pad 100. In other words, the headrest 101 and the positioning pad 100 can be connected by Velcro to use the head placement position of patients with different body shapes. When using it, the patient with cerebrospinal fluid leakage can place the head in the headrest 101, and adjust the leg height by the adjustable airbag 200 to achieve a head-low foot-high position. The utility model position pad has the advantages of simple operation, economical and applicable, does not affect the patient's view of objects from the top, can well improve the comfort of the lying position of the patient with cerebrospinal fluid leakage, meet the treatment needs, and improve the quality of nursing.

[0047] According to a preferred embodiment, the positioning pad 100 is also provided with a transverse structure 102 for horizontally placing the patient's arm. The transverse structure 102 is rotatably connected to the main structure of the positioning pad 100 located at the patient's waist. As a result, the patient can place his arm on the transverse structure 102. The transverse structure 102 can be rotationally limitedly connected to the main structure of the positioning pad 100 by a rotating shaft or a hinge. The transverse structure 102 serves as a receiving component after the patient's arm is unfolded, and can be used to receive the patient's hand when the patient needs an infusion. Furthermore, a detachable waterproof cloth cover can be provided on the surface of the positioning pad 100 to avoid the risk of leakage due to the drainage incision on the waist after surgery.

[0048] In order to facilitate understanding, the working principle and use method of the cerebrospinal fluid leakage posture correction device of the utility model are discussed.

[0049] First, the patient lies prone on the positioning pad 100, and places the head into the headrest 101, and the legs into the limiting structure 211. The patient keeps himself corresponding to the positioning pad 100 through the fixing belt 103 or other fixing devices on the positioning pad 100. The patient's family or medical staff can set at least one strip airbag 501 located at the patient's waist to increase the strength of fixation, and the strip airbag 501 can also be used to compress the patient's lumbar postoperative wound to promote healing. Then, the patient's family or medical staff can start the air pump to inflate the first airbag 201 and the second airbag 202 respectively. When the patient's thigh is raised to the required height, the patient's family or medical staff turns off the air pump connected to the first airbag 201. The second airbag 202 continues to inflate to continuously raise the patient's calf. When the patient's calf is raised to the required height or the overall lifting angle of the patient's lower limb reaches a specified angle, the patient's family or medical staff turns off the air pump connected to the second airbag 202, thereby completing the correction of the patient's body position.
