When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component. The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positions shown in the accompanying drawings and are only for the convenience of description and cannot be understood as limitations on the present technical solution. The terms "first" and "second" are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0052] like Figure 1 As shown, this embodiment proposes an arm fixing device for tube insertion, which is used to fix the patient's arm during the process of tracheal intubation, so that the arm can be spread out left and right and keep the spread out posture, so that medical staff can perform tracheal intubation at a better insertion angle. For the convenience of structural description, the left and right directions of the patient's body are used as the left and right directions of the structural description, the up and down directions of the patient when standing are the vertical directions, and the front and back directions of the patient are the front and back directions of the structural description of this embodiment. The various components of this embodiment are described structurally with the above directions as reference datums.

[0053] like Figure 1 , Figure 2 As shown, the arm fixing device for tube insertion in this embodiment mainly includes: a body abutment member 100, a first restraining member 200, an arm support member 300 and a second restraining member 400. The body abutment member 100 is used to abut against the patient's side waist and is located under the patient's arm. The first restraining member 200 is arranged on the body abutment member 100 and is used to be restrained on the patient's body; the first restraining member 200 can be a binding belt with a lock (such as a belt structure) or Velcro. The binding belt is wrapped around the patient, so that the body abutment member 100 is limited to the position below the patient's left or right armpit. The arm support 300 can be movably arranged on the body support 100 and used to support the patient's arm. The second binding member 400 is arranged on the arm support 300 and used to bind the patient's arm. The second binding member 400 can be arranged in plurality, and the plurality of second binding members 400 are arranged along the extension direction of the arm support 300. The arm support 300 extends in a straight line away from the body support 100 so that the patient's arm bound on the arm support 300 can be straightened. For example, when the body support 100 is bound under the armpit on the left side of the patient, the arm support 300 extends along the left side, and the extension length can be almost the same as the patient's arm length. The second binding member 400 can be a binding rope with a lock (such as a belt structure) or Velcro, which makes binding more convenient. The arm is bound by a plurality of binding ropes arranged on the arm support 300 in the left and right directions, so that the patient's arm is bound and will not move around.

[0054] like Figure 1 , Figure 2 As shown, an arm fixing device for tube insertion of this embodiment has a body abutment member 100 abutting against the patient's side waist and under the patient's arm, and the first restraining member 200 is tied to the patient's body to fix the body abutment member 100; the patient's arm is tied to the arm support member 300 by the second restraining member 400 to achieve support and limit the patient's arm. Since the arm support member 300 extends in a straight line away from the body abutment member 100, the patient's arm restrained on the arm support member 300 is straightened. Thus, the patient's arm is fixed by the arm fixing device, and during the process of tracheal intubation, the arm is prevented from moving randomly and affecting the tracheal intubation. In addition, during the tracheal intubation process, no other medical staff is required to assist in pressing the patient's arm, which makes the intubation process more convenient and improves the success rate of tracheal intubation.

[0055] like Figure 1 , Figure 2 , Figure 3As shown, further, the arm support 300 of this embodiment is movably connected with the body abutment 100 through the rotating bracket 500, and the rotating bracket 500 includes a first angle adjustment part 600, and the first angle adjustment part 600 is used to adjust the angle of rotation of the arm support 300 around the vertical direction. The first angle adjustment part 600 can make the arm support 300 rotate relative to the body abutment 100, and the arm support 300 rotates a certain angle with the vertical direction as the axis, so that the arm support 300 swings a certain angle between the left and right directions, thereby facilitating the angle adjustment of the arm support 300. The opening angle of the patient's arm can be adjusted, so that the doctor's tracheal intubation process is more convenient.

[0056] like Figure 2 , Figure 3 , Figure 4 As shown, further, the first angle adjustment part 600 of this embodiment specifically includes: a rotating seat 610, a rotating rod 620 and a first angle locking knob 630. The rotating seat 610 is set on the body abutment member 100, the rotating rod 620 is rotatably set on the rotating seat 610, the top of the rotating rod 620 is used to connect the arm support member 300, and the first angle locking knob 630 is connected to the rotating seat 610 and is used to fix the rotating rod 620 at a predetermined rotation position. The body abutment member 100 includes an arc plate 110, and the arc surface of the front of the arc plate 110 faces the side of the patient's body, so that it can abut against the side position of the patient's left armpit. The rotating seat 610 is fixedly set on the back of the arc plate 110 in the up-down direction, and the rotating rod 620 is installed on the rotating seat 610 in the up-down direction through a bearing, so that the rotating rod 620 can drive the arm support member 300 to rotate a certain angle. After adjusting to the preset angle, the first angle locking knob 630 is tightened to fix the rotating rod 620 at the angle position, so that the arm support 300 can be fixed at different angle positions to fix the patient's arm.

[0057] like Figure 2 , Figure 3 , Figure 4 As shown, further, the rotating bracket 500 also includes a second angle adjustment portion 700, which is arranged on the first angle adjustment portion 600 and is used to adjust the lifting angle between the arm support member 300 and the body abutment member 100. The second angle adjustment portion 700 is arranged on the upper part of the rotating rod 620, and the arm support member 300 can swing in the up and down direction through the second angle adjustment portion, so that the angle of the arm support member 300 in the up and down direction can be adjusted, which not only allows the arm support member 300 to adjust the lifting angle, but also allows it to be folded for easy storage. The lifting angle refers to the angle between the extension direction of the arm support member 300 and the vertical direction.

[0058] like Figure 2 , Figure 3 , Figure 4 As shown, further, the second angle adjustment part of this embodiment specifically includes: a hinge 710 and an adjustment screw rod 720. The hinge 710 has a fixed plate 711 and a lifting plate 713 hinged to the fixed plate 711, the fixed plate 711 is fixedly connected to the rotating rod 620, and the lifting plate 713 is fixedly connected to the arm support member 300. In the specific structure, the fixed plate 711 is fixedly set at the top of the rotating rod 620, and the lifting plate 713 is hinged to the fixed plate 711 on the side facing the body abutment member 100, so that the lifting plate 713 can be flipped upward toward the side of the body abutment member 100, and the lifting angle between the lifting plate 713 and the fixed plate 711 can be changed during the flipping process, and the arm support member 300 is fixedly connected to the lifting plate 713, so that the arm support member 300 can be adjusted to a predetermined lifting angle. The adjusting screw rod 720 is screwed on the first angle adjustment part 600, and one end of the adjusting screw rod is against the bottom of the arm support 300. The arm support 300 rotates around the hinge 710 by screwing the adjusting screw rod 720. The adjusting screw plate is screwed on the fixed plate 711 and is located below the lifting plate 713. Therefore, the adjusting screw plate can be raised or lowered by screwing the adjusting screw plate. The raising and lowering of the adjusting screw plate pushes the lifting plate 713 so that the lifting angle of the lifting plate 713 can be adjusted. When folding and storage are required, the body abutment 100 can be directly turned toward the arm support 300, so that the body abutment 100 and the arm support 300 are stacked together under the action of the hinge 710 to reduce the structural volume and facilitate storage.

[0059] like Figure 3 , Figure 5 As shown, the adjusting screw rod 720 of this embodiment can be tilted, and its head end gradually approaches the body abutment member 100 along the up and down direction. By using the tilted adjusting screw rod 720, the inclination of the lifting plate 713 can be increased during the twisting process.

[0060] like Figure 2 , Figure 3 , Figure 4As shown, further, the hinge 710 of this embodiment also includes: a fixed ring 712, a movable ring 714 and a hinge rod 715. The fixed ring 712 is connected to the fixed plate 711, the movable ring 714 is connected to the lifting plate 713, and the hinge rod 715 is inserted into the fixed ring 712 and the movable ring 714; through the cooperation of the fixed ring 712 and the movable ring 714, the lifting plate 713 drives the arm support member 300 to flip in a direction away from the adjustment screw rod 720, and fold with the body abutment member 100. In the specific structure, the fixed ring 712 is arranged on the side of the fixed plate 711 facing the body abutment 100. For example, when the hinge 710 is arranged along the front-to-back direction, a plurality of fixed rings 712 are arranged along the front-to-back direction (the axial direction of the hinge rod 715), and a hinge mounting groove 716 is formed between adjacent fixed rings 712; the movable ring 714 is arranged in the hinge mounting groove 716, so that the movable rod drives the lifting plate 713 to rotate around the hinge rod 715.

[0061] like Figure 2 , Figure 3 , Figure 4 As shown, in another structure, at least one side of the width direction of the arm support 300 of this embodiment is provided with a widening plate 320, and the widening plate 320 is retractably provided on the arm support 300. The width direction is perpendicular to the extension direction of the arm support 300. In the specific structure, the widening plates 320 are provided on both sides of the width direction of the arm support 300. When the arm is fixed, the width of the arm support 300 is increased by extending the widening plates 320 from both sides of the arm support 300, so that the arm support 300 has enough width to support the patient's arm, especially the patient's big arm, and the patient's arm fixation is more stable. When the arm fixing device is not used, the arm fixing device needs to be stored, and the widening plate 320 is retracted into the arm support 300, thereby reducing the width of the arm support 300 and making it more convenient to store.

[0062] like Figure 2 , Figure 3 , Figure 4As shown, further, in the specific structure of the widening plate 320 and the arm support 300 of this embodiment, a driving rod 321 is provided at one end of the widening plate 320 in the length direction, and the driving rod 321 is extended toward the fixing ring 712; a guide spiral groove 717 is provided on the outer wall of the fixing ring 712, and the driving rod 321 is movably arranged in the guide spiral groove 717; the rotation of the arm support 300 is used to drive the widening plate 320 to rotate, and the rotating driving rod 321 is converted into an axial movement along the hinge rod 715 in the guide spiral groove 717, so that the widening plate 320 can be extended and retracted on the arm support 300. Specifically, the length direction of the widening plate 320 is the extension direction of the arm support 300, and storage grooves 311 are provided on both sides of the width direction of the arm support 300, so that the widening plate 320 can extend out of the storage groove 311 or retract into the storage groove 311; the driving rod 321 is fixed to one end of the widening plate 320 and embedded in the guide spiral groove 717. The fixing rings 712 of this embodiment are respectively located on both sides of the width direction of the fixing plate 711 so that a hinged mounting groove 716 is formed in the middle of the fixing plate 711 facing the side of the body abutment 100, and the axial length of the fixing rings 712 located on both sides is greater than the width of the widening plate 320, so that when the guide spiral groove 717 is opened on the fixing ring 712, there is sufficient length to enable the driving rod 321 to move and guide the widening plate 320 to extend and retract. The specific shape of the guide spiral groove 717 on the outer wall of the fixing ring 712 is that the end of the fixing ring 712 facing the hinged installation groove 716 is the inner side, and the end away from the hinged installation groove 716 is the outer side. The guide spiral groove 717 is spirally wound around the fixing ring 712 with a length of 0.6-0.7 turns. The opening of the guide spiral groove 717 on the side close to the outer end of the fixing ring 712 is away from the body abutment 100, and the opening of the guide groove 312 on the side close to the inner end of the fixing ring 712 is toward the body abutment 100; the spiral direction of the guide spiral groove 717 is consistent with the folding direction, which is the direction in which the arm support member 300 rotates and folds toward the body abutment 100. Therefore, when the arm support 300 rotates and unfolds away from the body abutment 100, the widening plate 320 also rotates under the drive of the arm support 300, thereby driving the driving rod 321 to rotate around the fixed ring 712. During the rotation, the driving rod 321 gradually slides toward the outside of the fixed ring 712 along the trajectory of the guide spiral groove 717, so that the widening plate 320 is driven to move toward the outside of the storage groove 311 of the arm support 300 during the outward sliding of the driving rod 321, thereby realizing the unfolding of the widening plate 320.When the arm support 300 is rotated and folded toward the body abutment 100, the widening plate 320 is also rotated under the drive of the arm support 300, thereby driving the driving rod 321 to rotate around the fixed ring 712. During the rotation, the driving rod 321 gradually slides toward the inner side of the fixed ring 712 along the trajectory of the guide spiral groove 717, so that the widening plate 320 is driven to move toward the inner side of the storage groove 311 of the arm support 300 during the inward sliding of the driving rod 321, thereby realizing the storage of the widening plate 320.

[0063] In addition, in order to make the widening plate 320 more smoothly retractable, the distance between the inner wall of the end of the receiving groove 311 away from the body abutment 100 and the bottom of the guide spiral groove 717 is greater than the sum of the lengths of the widening plate 320 and the driving rod 321 in the length direction. For example, the inner side of the end of the receiving groove 311 away from the body abutment 100 can limit the widening plate 320, so that the widening plate 320 can be extended and retracted against the inner side of the end of the receiving groove 311 away from the body abutment 100; there is a small gap between the end of the driving rod 321 away from the widening plate 320 and the bottom of the guide spiral groove 717, so that during the guiding process of the guide spiral groove 717, only the two side walls of the guide spiral groove 717 are attached to the outer wall of the driving rod 321, thereby generating a driving force for the driving rod 321. In this way, interference with the driving rod 321 during the rotation process can be avoided, so that the widening plate 320 can be retracted and extended more smoothly.

[0064] like Figure 3 , Figure 6 , Figure 7 As shown, further, the arm support member 300 of this embodiment specifically includes: a main support plate 310, a telescopic plate 330 and a telescopic locking assembly 340. The main support plate 310 is movably arranged on the body abutment member 100, and the telescopic plate 330 is movably arranged on the main support plate 310 along the length direction of the main support plate 310; the telescopic locking assembly 340 is arranged on the main support plate 310 and is used to lock the telescopic plate 330. In the specific structure, the storage groove 311 is arranged on the main support plate 310, and the width of the main support plate 310 is larger than the width of the telescopic plate 330, so that the telescopic plate 330 can be telescoped along the main support plate 310, and the adaptability can be adjusted for patients with different arm lengths, and the versatility is strong. In addition, the telescopic plate 330 can be retracted with the main support plate 310, so as to reduce the overall length of the device, and it is more convenient to store when not in use.

[0065] like Figure 3 , Figure 6 , Figure 7As shown, further, in this embodiment, a guide groove 312 is provided on the main support plate 310, and a connecting rod 331 is provided on the telescopic plate 330, and the connecting rod 331 is movably inserted in the guide groove 312. The telescopic locking assembly 340 specifically includes: an extrusion block 341 and a telescopic locking screw 345. The extrusion block 341 is movably arranged in the main support plate 310, and the telescopic locking screw 345 is screwed on the main support plate 310 and movably connected with the extrusion block 341. The extrusion block 341 is driven to move in a direction toward or away from the connecting rod 331 by screwing the telescopic locking screw 345. In the specific structure, a latching tooth 343 is provided on the surface of the extrusion block 341, and a docking tooth 332 is provided on the surface of the connecting rod 331 facing the extrusion block 341 accordingly; guide blocks 342 are provided on both sides of the outer wall of the extrusion block 341, and a locking groove corresponding to the guide block 342 is provided in the main support plate 310, and the extrusion block 341 performs directional movement in the locking groove in the up and down directions. The end of the telescopic locking screw 345 located in the locking groove is provided with a T-shaped head 346, and the end of the extrusion block 341 away from the connecting rod 331 is provided with a T-shaped slot 344, which is connected to the T-shaped slot 344 through the T-shaped head 346, and the T-shaped head 346 can rotate in the T-shaped slot 344, so that when the telescopic locking screw 345 is screwed, it can push the extrusion block 341 to move up and down.

[0066] like Figure 1 , Figure 3 , Figure 6 As shown, in another structure, the arm support 300 of this embodiment is further provided with a hand grip 800 at one end away from the body abutment 100, and the hand grip 800 is held upward by the patient's palm to straighten the patient's arm on the arm support 300. Usually, during the process of related nursing work such as tracheal intubation, the patient will definitely have an uncomfortable reaction, and the hand grip 800 can be used to restrain the patient's hand. In addition, under the patient's uncomfortable emergency reaction, the patient's hand can hold the hand grip 800 with force to make the arm part straighter, so that when the arm is tied and fixed, it is conducive to straightening the arm and correcting the posture, so that the action of fixing the arm is more standardized. Third, the hand force can make the force point concentrated on the hand position, thereby relieving the muscle strength at the oral position, making the process of inserting the cannula into the oral cavity more favorable, and the hand as a force point can divert the patient's force point during the intubation process, play a role in distracting the patient's attention to a certain extent, thereby facilitating the smooth progress of the nursing work related to tracheal intubation.

[0067] like Figure 1 , Figure 3 , Figure 6As shown, further, the hand grip 800 of this embodiment specifically includes: a grip ring 810, an outer support member 820 and a hand grip elastic member 830. The grip ring 810 is arranged on the arm support member 300; the outer support member 820 is arranged on the side of the grip ring 810 away from the body abutment member 100; the hand grip elastic member 830 is arranged between the grip ring 810 and the outer support member 820; the patient's palm passes through the grip ring 810, so that the fingers hold the outer support member 820 upward, and the hand grip elastic member 830 applies elastic force to the outer support member 820, so that the outer support member 820 is away from the grip ring 810. After the fingers pass through the grip ring 810, it is convenient for the hand to hold the grip ring 810 upward to form a fist state, and the hand grip elastic member 830 provides an outward push force. When the patient's hand is in a fist state, the outward push force prompts the patient to make a fist, so that the force point is concentrated at the hand position, thereby relieving the muscle strength at the oral position, making the process of inserting the cannula into the oral cavity more favorable. In addition, a grip ring 810 is provided, and the palm passes through the grip ring 810, which can play a certain limiting role on the hand.

[0068] In addition, to facilitate storage, the grip ring 810 can be rotatably set on the arm support 300. For example, the grip ring 810 can be rotatable at the end of the arm support 300. When storage is required, the grip ring 810 is rotated to the same direction as the extension direction of the arm support 300, making storage more convenient.

[0069] In summary, the present application provides an arm fixing device for tube insertion, in which one end of the body abutment member is pressed against the lower side of the patient's arm near the chest, and the arm support member is arranged along the direction in which the arm is swung open and uses Velcro to restrain the patient's arm, thereby achieving the arm fixing function. The arm support member is retractable in the direction in which the arm extends, and the arm support member and the body abutment member can be folded in the upper and lower directions for easy storage. This eliminates the need for additional medical staff to assist in pressing the patient's arm during tracheal intubation, making the intubation process more convenient and improving the success rate of tracheal intubation.
