Description

Technical Field

[0001] This application belongs to the technical field of medical devices, and specifically relates to a body position cushion for hip fracture anesthesia. Background Art

[0002] Hip fractures in the elderly are often referred to as "the last fracture in life" because non-surgical conservative treatment can lead to various cardiopulmonary complications and a very high mortality rate. Surgery can improve the prognosis of patients, so 98% of elderly hip fractures require surgical treatment. However, elderly patients often suffer from multiple severe systemic diseases. Compared with general anesthesia, the incidence of cardiopulmonary complications, deep vein thrombosis, pulmonary embolism, delirium, and cognitive dysfunction in patients after regional anesthesia is lower. Therefore, spinal anesthesia is preferentially selected in clinical practice.

[0003] Hip fractures include intertrochanteric fractures, subtrochanteric fractures, and femoral neck fractures. During the anesthesia puncture process: due to the pain of the fracture, the patient cannot turn over to the lateral position by himself. First, the doctor or nurse assists the patient to switch the body position to the lateral position, and then the doctor or nurse assists the patient to flex the non-affected lower limb towards the abdomen. The patient bends forward and arches the back, assuming a head-down and back-bent posture. However, since the affected side (the fractured side) cannot be flexed, the affected limb is generally in a straight position. This body position often causes unbearable pain to the patient. The placement of the body position is very important for the success of spinal anesthesia puncture because a good body position will open the spinous process space, enabling the puncture needle to smoothly enter the intraspinal space. Due to factors such as age, the legs of the elderly are relatively fragile. After being injured, it is even more difficult to independently control leg movement, and it is also difficult for some special patients to adjust the leg position for better treatment. Utility Model Content

[0004] In order to better open the spinous process space, facilitate the placement of the body position for spinal anesthesia in patients with hip fractures, relieve the pain of patients, facilitate the smooth progress of spinal anesthesia puncture, and improve the puncture success rate, this application provides a body position cushion for hip fracture anesthesia.

[0005] A body position cushion for hip fracture anesthesia includes a main body, a locking member, a plurality of placing rollers, and four legs; the four legs are respectively connected to the main body through a height adjustment mechanism, and the height adjustment mechanism can adjust the height of the legs relative to the main body; the main body is provided with a placing groove penetrating the main body, and the bottom of the placing groove is arc-shaped; a plurality of placing rollers are arranged along the circumferential direction of the placing groove at the bottom of the placing groove, and the axis of the placing roller is parallel to the extending direction of the placing groove; the locking member is slidably connected to the main body, and the locking member can move between a first position and a second position. When the locking member is in the first position, the locking member is in contact with a plurality of placing rollers at the same time, restricting the rotation of each placing roller; when the locking member moves from the first position to the second position, the locking member is not in contact with a plurality of placing rollers and no longer restricts the rotation of a plurality of placing rollers.

[0006] In an embodiment of the present application, the direction collinear with the depth direction of the placement groove is the first direction, and the locking member can approach or move away from the plurality of placement rollers along the first direction; the first curved surface of the locking member can be in contact with the plurality of placement rollers simultaneously.

[0007] In an embodiment of the present application, elastic friction layers are provided on the side walls of the placement rollers and the first curved surface.

[0008] In an embodiment of the present application, the body position cushion for hip fracture anesthesia further includes an adjustment screw. The locking member is connected to the main body through the adjustment screw. When the adjustment screw rotates around its own axis, it can drive the locking member to approach the plurality of placement rollers so that the locking member is in contact with the plurality of placement rollers simultaneously.

[0009] In an embodiment of the present application, the axial direction of the adjustment screw is the same as the first direction.

[0010] In an embodiment of the present application, the direction collinear with the depth direction of the placement groove is the first direction; the height adjustment mechanism includes a height adjustment slider slidably connected to the main body. The height adjustment slider can move in the first direction, and the support leg is connected to the main body through the height adjustment slider.

[0011] In an embodiment of the present application, the height adjustment mechanism further includes a height adjustment screw. The axial direction of the height adjustment screw is the same as the first direction. The height adjustment screw connects the height adjustment slider and the main body. When the height adjustment screw rotates around its own axis, it drives the height adjustment slider to move along the first direction.

[0012] In an embodiment of the present application, the four support legs are divided into two groups of support units, and the two groups of support units are respectively arranged on both sides of the extending direction of the placement groove; each support leg is respectively connected to the working part in the height adjustment mechanism through a first pivot shaft. The support leg can rotate around the first pivot shaft to switch between the retracted state and the supporting state; when the support leg is in the retracted state, the support leg abuts against the main body; when the support leg is in the supporting state, the support leg supports the main body.

[0013] In an embodiment of the present application, the first pivot shaft is perpendicular to the longitudinal section of the placement groove and perpendicular to the depth direction of the placement groove.

[0014] In an embodiment of the present application, a handle is connected to the main body.

[0015] The present application has at least the following beneficial effects:

[0016] 1. The four support legs of the present application are respectively connected to the main body through the height adjustment mechanism, so that the height of the support ends of the four support legs relative to the main body can be adjusted independently, so that the main body has different inclination angles and heights, so that the legs placed in the placement groove can have different postures to better open the spinous process gap.

[0017] 2. The placement roller provided in the placement groove reduces the friction between the affected leg of the patient and the placement groove by rotating. Thus, when adjusting the main body's posture, the aggravation of the condition at the affected area can be avoided. After the main body is in a suitable posture, the locking member locks each placement roller to prevent relative movement between the main body and the affected leg during the puncture process, which may affect the puncture.

[0029] For a clearer understanding of the technical features, objectives, and effects of the present application, the specific embodiments of the present application will now be described with reference to the accompanying drawings. Components with the same reference numerals in the figures represent components with the same or similar structures but the same functions.

[0030] As used herein, "schematic" means "serving as an example, instance, or illustration", and any diagram or embodiment described as "schematic" herein should not be construed as a more preferred or advantageous technical solution.

[0031] For the sake of simplicity of the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product as a whole. Additionally, for the sake of simplicity and easy understanding of the drawings, among the parts with the same structure or function in some figures, only one of them is schematically shown, or only one of them is labeled.

[0032] Please refer to Figures 1 to 7 to understand the present application.

[0033] Refer to Figure 1 , a body position cushion for hip fracture anesthesia, which includes a main body 101, a locking member 201, a plurality of placing rollers 103, and four legs 301.

[0034] Refer to Figure 1 , Figure 2 , the main body 101 is provided with a placing groove 102 penetrating the main body 101, and the bottom of the placing groove 102 is arc-shaped, so that the patient's leg can be placed in the placing groove 102. And when the posture of the main body 101 changes and the placing groove 102 rotates relative to the patient's leg, due to the shape of the placing groove 102, the placing groove 102 can always support the patient's leg.

[0035] The four legs 301 are respectively connected to the main body 101 through a height adjustment mechanism, and the height adjustment mechanism can adjust the height of the legs 301 relative to the main body 101; in an embodiment of the present application, the direction collinear with the depth direction of the placing groove 102 is the first direction. Refer to Figure 3 , the height adjustment mechanism includes a height adjustment slider 302 slidably connected to the main body 101. The height adjustment slider 302 can move in the first direction, and the legs 301 are connected to the main body 101 through the height adjustment slider 302. Thus, when the height adjustment slider 302 moves in the first direction, it drives the legs 301 to move in the first direction, thereby changing the distance between the supporting end 305 of the legs 301 and the main body 101. During use, one leg of a patient in the lateral position can be placed in the placing groove 102, and the other leg can be placed between the four legs 301 below the placing groove 102.

[0036] In an embodiment of the present application, the height adjustment mechanism further includes a height adjustment screw 303. The axial direction of the height adjustment screw 303 is the same as the first direction. The height adjustment screw 303 connects the height adjustment slider 302 and the main body 101. When the height adjustment screw 303 rotates around its own axis, it drives the height adjustment slider 302 to move in the first direction. Refer to Figure 3, the height-adjusting screw 303 is rotatably connected to the main body 101. The height-adjusting screw 303 only rotates around its own axis relative to the main body 101. The height-adjusting screw 303 is threadedly connected to the height-adjusting slider 302. When the height-adjusting screw 303 rotates around its own axis, it drives the height-adjusting slider 302 to move in the first direction, thereby changing the distance between the support end 305 of the support leg 301 and the main body 101. The distances between the support ends 305 of the four support legs 301 and the main body 101 can be different from each other, thereby changing the pose of the placement groove 102, enabling the patient's leg to have different poses, so that the spinous process space can be fully opened and the puncture operation can be carried out smoothly.

[0037] Those skilled in the art to which this application belongs can understand that the setting manner of the height-adjusting mechanism in this application is not limited to the above manner, and there can also be other implementation manners. For example, the height-adjusting screw 303 is rotatably connected to the height-adjusting slider 302 and threadedly connected to the main body 101. Or, the height-adjusting mechanism includes an electric push rod, and the height-adjusting slider 302 is connected to the main body 101 through the electric push rod, thereby driving the height-adjusting slider 302 to move in the first direction. Of course, there are also other ways, which will not be elaborated here.

[0038] See Figure 1 , a plurality of placement rollers 103 are arranged on the bottom of the placement groove 102 along the circumferential direction of the placement groove 102. The axis of the placement roller 103 is parallel to the extension direction of the placement groove 102. The patient's leg can be placed on the plurality of placement rollers 103. When the pose of the main body 101 is adjusted, the placement rollers 103 can rotate to reduce the deformation of the patient's leg surface caused by the main body 101 and avoid the patient's leg being damaged by the main body 101.

[0039] See Figure 1 、 Figure 4 、 Figure 5 , the locking member 201 in this application is slidably connected to the main body 101. The locking member 201 can move between a first position and a second position. When the locking member 201 is in the first position, the locking member 201 abuts against a plurality of placement rollers 103 at the same time. The frictional force between the locking member 201 and the placement rollers 103 restricts the rotation of each placement roller 103. When the locking member 201 moves from the first position to the second position, the locking member 201 does not abut against the plurality of placement rollers 103 and no longer restricts the rotation of the plurality of placement rollers 103. Thus, when the pose of the main body 101 is adjusted, the placement rollers 103 can rotate to reduce the acting force of the main body 101 on the patient's leg and prevent the main body 101 from damaging the patient's leg. After the pose adjustment of the main body 101 is completed, the locking member 201 is adjusted to the first position, so that the locking member 201 locks each placement roller 103 to prevent the patient's leg from moving relative to the main body 101 during the puncture process and affecting the puncture.

[0040] See Figure 1 、Figure 4 , Figure 5 , in an embodiment of the present application, the direction collinear with the depth direction of the placement groove 102 is the first direction, and the first direction is the same as the axial direction of the adjusting screw 202 in Figure 4 . The locking member 201 can approach or move away from the plurality of placement rollers 103 along the first direction; the first curved surface 203 of the locking member 201 can be in contact with the plurality of placement rollers 103 simultaneously.

[0041] Furthermore, elastic friction layers are provided on the side walls of the placement rollers 103 and the first curved surface 203. The elastic friction layers can be made of materials such as rubber and silica gel, so as to increase the friction force between the placement rollers 103 and the first curved surface 203. And the elastic friction layers provided on the placement rollers 103 can undergo elastic deformation to improve the comfort of the patient; and when the locking member 201 restricts the rotation of the placement rollers 103, the elastic friction layers can prevent relative movement between the patient's legs and the placement rollers 103 and avoid affecting the puncture.

[0042] See Figure 1 , Figure 4 , Figure 5 , in an embodiment of the present application, the body position cushion for hip fracture anesthesia further includes an adjusting screw 202. The locking member 201 is connected to the main body 101 through the adjusting screw 202. When the adjusting screw 202 rotates around its own axis, it can drive the locking member 201 to approach the plurality of placement rollers 103, so that the locking member 201 is in contact with the plurality of placement rollers 103 simultaneously. Furthermore, the axial direction of the adjusting screw 202 is the same as the first direction, so as to facilitate the medical staff to adjust the position of the locking member 201 relative to the plurality of placement rollers 103.

[0043] Those skilled in the art to which the present application pertains can understand that the setting method of the adjusting screw 202 in the present application is not limited to the above method, and can also be other methods. For example, the adjusting screw 202 is arranged along the extension direction of the placement groove 102, and the locking member 201 is provided with an inclined surface. When the adjusting screw 202 presses the inclined surface of the locking member 201, the locking member 201 moves along the first direction and is pressed to the first position, so that the locking member 201 locks each placement roller 103. When the adjusting screw 202 does not press the inclined surface of the locking member 201, the friction force between the locking member 201 and the placement roller 103 is not sufficient to restrict the rotation of the placement roller 103, so that the placement roller 103 can rotate freely.

[0044] See Figure 1 , Figure 6 , Figure 7, in an embodiment of the present application, the four legs 301 are divided into two groups of support units, and the two groups of support units are respectively arranged on both sides of the extending direction of the placement groove 102; each leg 301 is respectively connected to the working part in the height adjustment mechanism through a first pivot shaft 304, see Figure 1 , the leg 301 is pivotally connected to the height adjustment slider 302 through the first pivot shaft 304, the height adjustment slider 302 is the working part, and the leg 301 can rotate around the first pivot shaft 304 to switch between the retracted state and the supported state; when the leg 301 is in the retracted state, the leg 301 abuts against the main body 101; when the leg 301 is in the supported state, the leg 301 supports the main body 101. When the legs 301 in one group of support units are in the retracted state, the legs 301 in the other group of support units can be in the supported state, so that the main body 101 is inclined, which is convenient for putting the affected leg of the patient into the placement groove 102. Then, the main body 101 is rotated around the leg 301 in the supported state, so that the main body 101 is placed horizontally. Then, the legs 301 in the retracted state are switched to the supported state, so that the four legs 301 can support the main body 101, which is convenient for medical staff to help the patient switch positions, so that the patient is switched from the supine position to the lateral position; at the same time, the placement roller 103 in the placement groove 102 can rotate, which can reduce the possibility of the leg in the placement groove 102 being injured during the movement of the main body 101.

[0045] Those skilled in the art to which the present application belongs can understand that the legs 301 in the present application can be in a locked state when in the supported state. For example, through the cooperation of the fixing pin and the pin holes provided on the legs 301 and the height adjustment sliders 302, the legs 301 are prevented from rotating during the process of adjusting the position and posture of the main body 101. When it is necessary to switch the legs 301 to the retracted state, the locking of the legs 301 is released, so that the legs 301 can rotate around the first pivot shaft 304. Of course, there are other ways to ensure the stability of the legs 301 when in the supported state, which will not be elaborated here.

[0046] In an embodiment of the present application, the first pivot shaft 304 is perpendicular to the longitudinal section of the placement groove 102 and perpendicular to the depth direction of the placement groove 102, so as to reduce the possibility of the legs 301 rotating when a force perpendicular to the longitudinal section of the placement groove 102 and perpendicular to the depth direction of the placement groove 102 is applied when placing the patient's leg in the placement groove 102, and to avoid secondary trauma to the patient.

[0047] See Figure 1 , Figure 5 , in an embodiment of the present application, the main body 101 is connected with a handle 104, which is convenient for medical staff to carry the patient's leg by using the main body 101.

[0048] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0049] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of this application, and they are not intended to limit the protection scope of this application. Any equivalent implementation or change made without departing from the technical spirit of this application, such as the combination, division or repetition of features, should be included in the protection scope of this application.
