Technical Field
[0001] The present disclosure relates to the field of surgical auxiliary equipment, and in particular to a limb support bracket for radial artery angiography. Background Art
[0002] Radial artery puncture is a commonly used medical method. At present, when doctors puncture the right radial artery of patients, they usually stand on the right side of the patient for the convenience of operation. However, when the doctor fails to puncture the radial artery with his right hand or the right radial artery pulse is weak, and he needs to change his left hand to puncture the radial artery, the doctor usually chooses to go around the bed to the left side of the patient to puncture, or use the existing radial artery angiography limb support bracket. Most of the existing brackets raise and rotate the patient's left arm to make the patient's left arm close to the right arm, so that the doctor can directly puncture the patient's left radial artery without moving. However, when the existing bracket is used, the patient's arm is easily twisted unnaturally and feels uncomfortable when rotating because the radial artery is exposed to the field of vision of medical staff; secondly, the arm is kept in an unnatural posture for a long time, which is easy to cause damage to the patient's arm.

[0010] In an embodiment of the first aspect, the radial artery angiography limb support bracket also includes a first limiting component, which includes at least one first limiting portion and a first clamping portion; the multiple first limiting portions are formed on the side wall of the swinging member at intervals along the length direction of the swinging member, and the first clamping portion is slidably engaged with the fixing member and passes through one end of the fixing member to engage with one of the first limiting portions.
[0011] In an embodiment of the first aspect, the support member is ball-hingedly connected to the swing member.
[0012] In an embodiment of the first aspect, friction between the support member and the swing member enables the support member to remain stable when supporting the patient's arm.
[0013] In an embodiment of the first aspect, a first avoidance area is formed on the top of the fixing member for avoiding the connection between the supporting member and the swinging member, so that the supporting member is in a horizontal state when abutting against the fixing member.
[0014] In an embodiment of the first aspect, a second avoidance area recessed inwardly is formed on a wall surface of the swinging member facing the hospital bed.
[0015] In an embodiment of the first aspect, the length of the support member enables the patient's palm to remain on the support member during the exercise.
[0016] In an embodiment of the first aspect, the swinging member is connected to a driving device and can be driven by the driving device to perform the movement; the driving device includes a wireless receiver, and the wireless receiver is connected to a remote control to receive a remote control signal for triggering the driving action of the driving device on the swinging member.

[0032] Radial artery puncture is a commonly used medical method. At present, when doctors puncture the right radial artery of patients, they usually stand on the right side of the patient for the convenience of operation. However, when the doctor fails to puncture the radial artery with his right hand or the right radial artery pulse is weak, and he needs to change his left hand to puncture the radial artery, the doctor usually chooses to go around the bed to the left side of the patient to puncture, or use the existing radial artery angiography limb support bracket. Most of the existing brackets raise and rotate the patient's left arm to make the patient's left arm close to the right arm, so that the doctor can directly puncture the patient's left radial artery without moving. However, when the existing bracket rotates, the patient's arm is easily twisted unnaturally and feels uncomfortable because the radial artery is exposed to the field of vision of medical staff; secondly, the arm is kept in an unnatural posture for a long time, which is easy to cause damage to the patient's arm.
[0033] Based on the above problems, an embodiment of the present disclosure provides a limb support bracket for radial artery angiography, wherein the support member drives the patient's left arm along a spherical arc trajectory toward the right side of the bed, so that the patient's left arm can be in a comfortable state when approaching the right side of the bed, and at the same time, the patient's left arm is in a posture that allows medical staff to smoothly perform radial artery puncture on the right side of the bed.
[0034] Figure 1 The figure shows a cross-sectional schematic diagram of the overall structure of the radial artery angiography limb support bracket in the present disclosure in its initial state. Figure 1 In the example, the radial artery angiography limb support bracket includes a fixing member 10 , a swinging member 20 and a supporting member 30 .
[0035] The fixing member 10 is detachably arranged on the left side of the bed. The swinging member 20 is connected to the fixing member 10 so as to be movable along an arc track in the width direction of the bed toward the right side of the bed. The supporting member 30 is connected to the swinging member 20 so as to be driven by the swinging member 20 toward the right side of the bed. It can be understood by those skilled in the art that the supporting member 30 drives the patient's left arm toward the right side of the bed along a spherical arc track so that the patient's left arm can be in a comfortable state when approaching the right side of the bed, and at the same time, the left arm is in a posture that the medical staff can smoothly perform left-hand radial artery puncture on the right side of the bed.
[0036] For example, the support member 30 is connected to the swing member 20 by a ball hinge. The friction between the support member 30 and the swing member 20 allows the support member 30 to remain stable when supporting the patient's arm. In this way, the ball hinge method enables the support member 30 to keep the patient's left arm in a natural state when the swing member 20 moves along the arc track, thereby improving the comfort of the patient's arm.
[0037] exist Figure 1In the example, the swing member 20 is implemented as an arc shape, the swing member 20 is slidably coupled to the fixing member 10 in an adjustable position, and the support member 30 is connected to an end of the swing member 20 that is exposed upward from the fixing member 10. Exemplarily, the arc opening of the arc in the initial state faces the upper right.
[0038] Figure 2 The present disclosure is shown in Figure 1 A top view of the fixed frame in the example. Figure 2 In the example, the fixing member 10 forms an arc-shaped slide groove 101 for the swing member 20 to slide. The support member 30 is connected to the end of the swing member 20 that is exposed upward from the arc-shaped slide groove 101. Further exemplarily, the end of the arc-shaped slide groove 101 that is close to the bed in the width direction points to the head of the bed, so when the swing member 20 slides upward in the arc-shaped slide groove 101, it can drive the patient's left arm to swing along a spherical trajectory through the support member 30, thereby avoiding discomfort caused by unnatural twisting of the patient's left arm during the swing.
[0039] Exemplarily, a first avoidance area 11 is formed on the top of the fixing member 10 to avoid the connection between the support member 30 and the swing member 20, so that the support member 30 is in a horizontal state when abutting against the fixing member 10. The advantage of such a setting is that the comfort of the present invention can be further improved. At the same time, by setting the length of the fixing member 10 and the depth of the first avoidance area 11, the support member 30 can be prevented from protruding from the upper surface of the bed.
[0040] Exemplarily, the radial artery angiography limb support bracket further includes a first limiting component 40, which includes at least one first limiting portion 41 and a first clamping portion 42; the first limiting portion 41 is formed on the side wall of the swinging member 20 away from the support member 30, and exemplarily, the first limiting portion 41 is formed on the arc-shaped side wall surface of the swinging member 20. The first clamping portion 42 is slidably combined with the fixing member 10 and passes through one end of the fixing member 10 to be engaged with the first limiting portion 41. That is, when the patient's left arm needs to be close to the arm on the right side of the bed, the first clamping portion 42 is disengaged from the first limiting portion 41, and the swinging member 20 is pushed upward, so that the swinging member 20 slides upward along the arc-shaped slide groove 101 until the first clamping portion 42 is aligned with the first limiting portion 41, and then the first clamping portion 42 is pushed to be engaged with the first limiting portion 41, thereby realizing the position limitation of the swinging member 20 and the support member 30.
[0041] Exemplarily, the arc opening of the arc in the use state faces the lower right. Exemplarily, the end of the swing member 20 away from the support member 30 is disassembled with an operating end 21. The operating end 21 can facilitate the operator to apply force to the swing member 20, and can prevent the swing member 20 from slipping out of the arc-shaped slide groove 101.
[0042] In another embodiment, the first limiting portion 41 is formed on other sidewall surfaces of the swinging member 20 , and the position of the sliding engagement between the first clamping portion 42 and the fixing member 10 is changed accordingly.
[0043] In another embodiment, the limiting assembly 40 includes a plurality of first limiting portions 41 and a first clamping portion 42; the plurality of first limiting portions 41 are formed on the arc-shaped side wall of the swinging member 20 at intervals along the length direction of the swinging member 20, and the first clamping portion 42 is slidably coupled to the fixing member 10 and one end of the fixing member 10 is engaged with one of the first limiting portions 41. In this way, medical staff can adjust the swing amplitude of the patient's left arm driven by the support member to the right side of the bed by engaging the first clamping portion 42 in the first limiting portion 41 at different positions.
[0044] Figure 3 The figure shows a cross-sectional view of the overall structure of another embodiment of the radial artery angiography limb support bracket disclosed in the present invention. Figure 3 In the example, the swing member 20A is implemented as a straight line, the swing member 20A is hinged to the fixing member 10 with an adjustable swing angle, and the support member 30 is connected to one end of the swing member 20A that is exposed upward from the fixing member 10. Further exemplarily, the radial artery angiography limb support bracket also includes a second limiting component 50, and the limiting component includes at least one second limiting portion 51 and a second clamping portion 52; the one second limiting portion 51 is formed on the side wall of the swing member 20A facing the foot of the bed, the second clamping portion 52 is slidably combined with the side wall of the fixing member 10 facing the head of the bed, and the second clamping portion 52 passes through one end of the fixing member 10 and is engaged with the second limiting portion 51.
[0045] For example, after the fixing frame 10 is installed on the bed, at least one side wall 110 is inclined with respect to the length direction of the bed, and the inclined side wall 110 is close to the end of the bed and points to the head of the bed. The swing member 20 is hinged to the side wall 110. The advantage of such a setting is that the support member 30 can drive the patient's left arm to swing along a spherical trajectory, thereby avoiding discomfort caused by unnatural twisting of the patient's left arm during the swing.
[0046] Figure 4 The present disclosure is shown in Figure 3 A top view schematically showing a first embodiment in which a fixing frame is connected to a hospital bed in the example.
[0047] Figure 5 The present disclosure is shown in Figure 3 A schematic top view of a second embodiment of the example in which a fixing frame is connected to a hospital bed.
[0048] Back to Figure 3 In the example, the wall of the swing member 20 facing the bed is formed with an inwardly recessed second avoidance area 201. The second avoidance area 201 can prevent the swing member 20 from causing damage to the patient's body due to contact with the patient's body when swinging along the arc track.
[0049] Exemplarily, the length of the support member 30 allows the patient's palm to remain on the support member 30 during the movement. Further exemplary, the support member 30 is implemented in an arc shape with the arc opening facing away from the bed.
[0050] In this way, when the swing member 20 swings along the arc trajectory, the patient's left arm can adjust its posture on the support member 30 with natural limb flexion to be in a comfortable and natural state. In this process, since the support member 30 is relatively long, the patient's left palm can always be supported by the support member 30, so that when it swings to a predetermined posture, it can avoid the patient's palm being out of contact with the support member 30, which can affect the medical staff's left hand radial artery puncture.
[0051] Exemplarily, the wall surface of the support member 30 that contacts the patient's arm is provided with a soft pad 31, such as a sponge pad, to improve the comfort of the patient's arm.
[0052] In another embodiment, the support plate 30 is provided with a plurality of pairs of fixing straps spaced apart along its length direction, and the free ends of each pair of the fixing straps are connected by Velcro, thereby cooperating with the wall surface of the support member 30 to restrain the patient's arms to the support member 30, so as to further facilitate puncture by medical staff.
[0053] exist Figure 1 In the example, the fixing member 10 includes a fixing frame 12 clamped on the bed and a screw 13 threadedly connected to the bottom wall of the fixing frame 12; the fixing frame 12 has a clamping opening 1201 for accommodating the bed, and one end of the screw 13 inserted into the clamping opening 1201 presses against the bed. Exemplarily, a force-applying member 131 is provided at one end of the screw 13 inserted into the clamping opening 1201. The area of the force-applying member 131 is larger than the cross-sectional area of the end of the screw 13, so as to prevent the screw 13 from causing damage to the bed when pressing against the bed.
[0054] Exemplarily, the swing member 20 is connected to a driving device (not shown) and can be driven by the driving device to perform the movement; the driving device includes a wireless receiver, and the wireless receiver is connected to a remote controller to receive a remote control signal for triggering the driving action of the driving device on the swing member 20. The advantage of this arrangement is that when the medical staff on the right side of the bed needs to perform radial artery puncture on the left arm of the patient, the driving device can drive the swing member 20 to move along the arc track by operating the remote controller, thereby realizing that the medical staff no longer need to operate manually, reducing the workload of the medical staff and improving the operation efficiency.
[0055] In summary, a radial artery angiography limb support bracket is provided in an embodiment of the present disclosure, comprising a fixing member, a swinging member and a supporting member. The fixing member is detachably arranged on the left side of the bed; the swinging member can be connected to the fixing member so as to move along an arc trajectory toward the right side of the bed in the width direction of the bed; the supporting member is connected to the swinging member so as to be driven by the swinging member to approach the right side of the bed. The advantage of such a setting is that the supporting member drives the patient's left arm along a spherical arc trajectory toward the right side of the bed, so that the patient's left arm can be in a comfortable state when approaching the right side of the bed, and at the same time, the left arm is in a posture that medical staff can smoothly perform radial artery puncture.
[0056] The above embodiments are merely illustrative of the principles and effects of the present disclosure, and are not intended to limit the present disclosure. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in the present disclosure shall still be covered by the protection scope of the present disclosure.
