Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a fixing device for opening the airway of a patient. Background Art

[0002] Now in clinical medicine, sometimes it is necessary to anesthetize a patient during treatment so as to facilitate the rescue work. However, for some comatose patients, their airways are in a closed state. At this time, medical staff need to open the airway of the comatose patient first and then can anesthetize the patient.

[0003] In the prior art, most often a lifting device is arranged on the patient's neck to raise the patient's mandible, so as to open the patient's airway. However, the following problems will exist in actual operation:

[0004] 1. The mandible of the patient is not limited in the existing device. On the one hand, it may cause the patient's head to rotate during the lifting process, resulting in the patient's airway being blocked and other situations. Seriously, it may cause the patient to suffocate, presenting a safety hazard.

[0005] 2. The operation area of the existing device is on the patient's neck. During the operation, if adjustment is needed (such as the patient's body shifting, etc.), the anesthesiologist needs to move to the side of the patient to make the adjustment, thus reducing the activity area of the surgeon during the operation and interfering with the operation. Summary of the Utility Model

[0006] In order to solve the above problems, the purpose of the utility model is to provide a fixing device for opening the airway of a patient, which limits the mandible of the patient and moves the operation space to the forehead of the patient, reducing the interference of opening the airway on the operation.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A fixing device for opening the airway of a patient includes fixing components symmetrically arranged on the left and right sides of the bed board of the operating table, a rotating rod rotatably arranged circumferentially between the two fixing components, and an airway opening component movably sleeved outside the rotating rod and perpendicular to the rotating rod; the airway opening component includes a collar rotatably sleeved outside the rotating rod, a C-shaped fixing strip fixed to the front side of the collar, a pressing block installed below the front part of the C-shaped fixing strip and abutted against the patient's forehead, and a fastening sub-component fixed to the rear side of the collar. The fastening sub-component includes a pair of connecting rods symmetrically fixed at both ends of one side of the collar, and a pair of fastening pieces respectively rotatably connected to the movable ends of the corresponding connecting rods and used for buckling on both sides of the patient's mandible.

[0009] Preferably, the fixing component includes two hinged mounting blocks, a reset spring arranged between the two mounting blocks, a telescopic rod fixed to the top of the mounting block at the top, and a mounting plate fixed to the driving end of the telescopic rod; both axial ends of the rotating rod are respectively fixed to the corresponding mounting plates.

[0010] Preferably, a first elastic sleeve is sleeved outside the fastening member, and a second elastic sleeve is sleeved outside the pressing block.

[0011] Preferably, the airway opening component further includes holding rods symmetrically arranged on both sides of the C-shaped fixing strip, and a handle is arranged at the end of the holding rod.

[0012] Preferably, the airway opening component further includes a constraint sub-component arranged on the pressing block for restricting the rotation of the airway opening component; the constraint sub-component includes a fixing ring fixed to one end of the top side of the pressing block and a constraint belt fixed to the other end of the top side of the pressing block and cooperating with the fixing ring for fixation.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model fastens the two fastening members to both sides of the patient's mandible respectively. While lifting the patient's mandible, it can limit the patient's head from both sides, thus avoiding the rotation of the patient's head when lifted, etc., thereby avoiding the situation of unsmooth airway of the patient, and further avoiding suffocation caused by the rotation of the patient's head, improving the safety during anesthesia;

[0015] 2. Through the cooperation of the pressing block, C-shaped fixing strip, collar, fastening member and connecting rod, the utility model can realize that when pressing down the pressing block, the fastening members respectively fastened to both sides of the patient's mandible will drive the patient's mandible to move upward, so as to open the patient's airway. On the one hand, in this device, the length of the connecting rod is less than that of the C-shaped fixing strip, and the force required to lift the patient's mandible can be saved through the lever principle. On the other hand, when the angle of lifting the patient's mandible needs to be adjusted, the anesthesiologist does not need to move to the side of the patient to adjust the lifting angle, thus reducing the activities of the anesthesiologist in the surgical area and reducing the interference with the operation.

[0023] The following further describes the present utility model in detail with reference to the drawings and specific embodiments.

[0024] A fixing device for opening the airway of a patient includes fixing components 1 symmetrically arranged on the left and right sides of the bed board of the operating table, a rotating rod 2 rotatable circumferentially between the two fixing components 1, and an airway opening component 3 movably sleeved outside the rotating rod 2 and perpendicular to the rotating rod 2; the airway opening component 3 includes a collar 31 rotatably sleeved outside the rotating rod 2, a C-shaped fixing strip 32 fixed to the front side of the collar 31, a pressing block 33 installed below the front part of the C-shaped fixing strip 32 and abutted against the forehead of the patient, and a buckling sub-component 34 fixed to the rear side of the collar 31. The buckling sub-component 34 includes a pair of connecting rods 341 symmetrically fixed to both ends of one side of the collar 31 and a pair of buckling members 342 respectively rotatably connected to the movable ends of the corresponding connecting rods 341 and used for buckling on both sides of the patient's mandible.

[0025] In this device, the two buckling members 342 are respectively buckled on both sides of the patient's mandible. While lifting the patient's mandible, it can limit the patient's head from both sides, thereby preventing the patient's head from rotating when lifted, etc., thus avoiding situations such as unsmooth airway of the patient, and further avoiding suffocation caused by the rotation of the patient's head, improving the safety during anesthesia; through the cooperation of the pressing block 33, the C-shaped fixing strip 32, the collar 31, the buckling member 342 and the connecting rod 341, it can be realized that when pressing down the pressing block 33, the buckling members 342 respectively buckled on both sides of the patient's mandible will drive the patient's mandible to move upward, so as to open the patient's airway. On the one hand, in this device, the length of the connecting rod 341 is less than that of the C-shaped fixing strip 32, and the force required to lift the patient's mandible can be saved through the lever principle. On the other hand, when it is necessary to adjust the angle of lifting the patient's mandible, the anesthesiologist does not need to move to the side of the patient to adjust the lifting angle, thereby reducing the activities of the anesthesiologist in the surgical area and reducing the interference with the operation.

[0026] As a possible implementation of this solution, preferably, the fixing component 1 includes two hinged mounting blocks 11, a return spring 12 disposed between the two mounting blocks 11, a telescopic rod 13 fixed to the top of the mounting block 11 at the top, and a mounting plate 14 fixed to the driving end of the telescopic rod 13; both ends of the rotating rod 2 are respectively fixed to the corresponding mounting plates 14; the two mounting blocks 11 are fixed to the edge of the operating bed under the action of the return spring 12, so as to realize the fixation of the device. On the one hand, the stability of the device can be improved, and on the other hand, quick disassembly can be realized; the setting of the telescopic rod 13 enables the height of the device to be adjusted according to the height of the patient's head and the angle by which the patient's mandible needs to be lifted, so as to avoid excessive or insufficient lifting amplitude of the patient's mandible when the pressing block 33 rotates to abut against the patient's forehead, thereby avoiding the obstruction of the airway opening caused by excessive or insufficient lifting angle of the mandible, and further avoiding the risk of patient asphyxia.

[0027] As a possible implementation of this solution, preferably, a first elastic sleeve 343 is sleeved outside the fastening member 342, and a second elastic sleeve 331 is sleeved outside the pressing block 33; through the settings of the first elastic sleeve 343 and the second elastic sleeve 331, on the one hand, cross-infection between patients can be avoided, and on the other hand, the comfort of the patient when using the device can be improved.

[0028] As a possible implementation of this solution, preferably, the airway opening component 3 further includes gripping rods 35 symmetrically disposed on both sides of the C-shaped fixing strip 32, and a grip 36 is provided at the end of the gripping rod 35; through the gripping rods 35 and the grip 36, it is convenient for an anesthesiologist to press the pressing block 33.

[0029] As a possible implementation of this solution, preferably, the airway opening component 3 further includes a constraint sub-component 37 disposed on the pressing block 33 for restricting the rotation of the airway opening component 3; the constraint sub-component 37 includes a fixing ring 371 fixed to one end of the top side of the pressing block 33 and a constraint band 372 fixed to the other end of the top side of the pressing block 33 and cooperating with the fixing ring 371 for fixation; through the cooperation of the fixing ring 371 and the constraint band 372, the constraint of the pressing block 33 can be realized, so as to avoid the automatic downward rotation of the patient's head resulting in airway closure when the anesthesiologist accidentally releases the fixation of the airway opening component 3, and further resulting in the risk of patient asphyxia.

[0030] The working principle of this device is as follows:

[0031] During use, first fix the fixing components 1 on both sides to both sides of the operating table. Adjust the height of the device according to the height of the patient's head and the height that the patient's mandible needs to be lifted. Fasten the two fastening members 342 to both sides of the patient's mandible respectively, lift the patient's head, pass the restraint strap 372 around the back of the patient's head, and then hold the grip 36 and press downwards so that the pressing block 33 abuts against the patient's forehead. At this time, the patient's mandible is lifted upwards under the action of the fastening member 342 and the airway is opened. Then, pass the end of the restraint strap 372 through the fixing ring 371 and buckle it back to achieve fixation. In this device, the C-shaped fixing strip 32 and the connecting rod 341 are both ergonomic. At the same time, in this device, the length of the C-shaped fixing strip 32 is greater than the length of the connecting rod 341.

[0032] The above are only the specific embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
