Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an arm supporting device. Background Art

[0002] PICC central venous catheter puncture is a deep vein catheterization technique for central venous catheterization via peripheral venous puncture. The catheter is implanted through the peripheral (basilic vein, median cubital vein, cephalic vein) axillary vein, subclavian vein, and innominate vein to the junction of the middle and lower 1 / 3 of the superior vena cava and the right atrium for infusion and nutritional therapy. The retention time can be more than 1 year.

[0003] During puncture, the patient usually lies flat with the arm abducted at 45 to 90 degrees to the trunk. This ensures that the puncture site is fully exposed and facilitates the nurse to perform the puncture operation. However, due to the limited space of the bed, the patient's arm often needs to be extended to the outside of the bed and suspended in the air when abducted. This not only increases the discomfort of the hand, but also makes it difficult for the patient's arm to maintain stability in this state, which easily increases the risk of puncture. Utility Model Content

[0004] The utility model aims to provide an arm support device which can support a patient's arm when the patient's arm is abducted and improve the stability of the arm.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] An arm support device includes a support plate body, a slot is provided inside the support plate body, an extended support plate is inserted inside the slot, and a fastening bolt for fixing the extended support plate is installed on the lower surface of the support plate body. A bottom plate is rotatably installed on the lower surface of the support plate body through a connecting shaft, a fixing plate is provided on the lower side of the bottom plate, a lifting mechanism capable of adjusting the height of the support plate body is provided on the fixing plate, and a fixing mechanism capable of fixing the support plate body on a bed is provided on the lower side of the fixing plate. An annular plate is installed on the lower surface of the support plate body, and the annular plate is coaxially arranged with the connecting shaft, a plurality of plug holes are provided on the surface of the annular plate in a coaxial array, and a positioning mechanism capable of plugging and cooperating with the plug holes is provided on the outer side of the bottom plate.

[0007] It can be seen that the device can be fixed on the bed through the fixing mechanism, and then the patient places the arm on the support board body to support the arm, thereby improving the stability of the patient's arm and reducing the risk of puncture, and by extending the support board, the support length of the arm can be extended, so it is suitable for patients with different arm lengths, and when not in use, it can also be stored to reduce the occupied space. Through the setting of the fixing mechanism, the height of the support board body can be adjusted, so that the support board body and the patient's body are at the same level. In the case of needing to maintain the arm posture for a long time, the patient's discomfort can be reduced and the convenience of operation for medical staff can be increased. Through the setting of the positioning mechanism, the angle of the support board body can be adjusted, and then the angle of the patient's arm can be adjusted, which helps to improve the accuracy and safety of the operation and improve the patient's comfort.

[0008] Furthermore, the lifting mechanism includes a first screw rod that passes through the interior of the fixed plate and is threadedly connected thereto, and the end of the first screw rod is rotatably connected to the lower surface of the base plate, a first knob is installed at the bottom of the first screw rod, and four limit rods are connected to the lower surface of the base plate in a coaxial array, and the end of the limit rod passes through the lower side of the fixed plate, and a limit block is installed at the end of the limit rod.

[0009] After the fixing plate is fixed to the bed by the fixing mechanism, the first knob is turned to drive the first screw to rotate. Since the bottom plate is limited by the four limit rods, the bottom plate can be driven to rise and fall, and the height of the support plate body can be adjusted so that the patient's arm can be at the same level as the torso when placed on the support plate body.

[0010] Furthermore, the fixing mechanism includes an L-shaped plate installed on the lower surface of the fixing plate, a second screw rod passes through the interior of the L-shaped plate and is threadedly connected, a pressure block is installed at the upper end of the second screw rod, and a second knob is installed at the bottom of the second screw rod.

[0011] During installation, the fixing plate and the L-shaped plate are clamped on the upper and lower sides of the bed respectively, and then the second knob is turned to drive the second screw to rotate, thereby driving the pressing block to rise and press against the lower side of the bed, thereby achieving the installation and fixation of the device.

[0012] Furthermore, the positioning mechanism includes a hollow tube installed on the side surface of the fixed plate, a positioning rod is inserted into the interior of the hollow tube, and the end of the positioning rod is plugged into the socket, a shoulder is provided on the outer surface of the positioning rod, a spring is sleeved on the outer surface of the positioning rod, and both ends of the spring are respectively abutted against the shoulder and the inner wall of the hollow tube.

[0013] When the patient's arm angle needs to be adjusted, the positioning rod can be pulled downward to drive its end to be pulled out of the socket, and drive the shoulder to compress the spring. Then the support plate body can be rotated to adjust its angle. When the angle is adjusted, release the positioning rod. At this time, the compressed spring pushes the shoulder upward, thereby driving the positioning rod to move upward and reinsert into the socket, so that the support plate body can be fixed at the current angle and the purpose of adjusting the patient's arm angle is achieved.

[0014] Furthermore, a treatment tray is installed at the end of the extended support plate.

[0015] Through the setting of the treatment tray, puncture supplies can be placed, making it convenient for medical staff to take and use them.

[0016] Furthermore, the upper surfaces of the support plate body and the extended support plate are both provided with rubber pads, and the outer surfaces of the rubber pads are provided with anti-slip grooves.

[0017] The provision of the rubber pad can improve the comfort of the patient's arm, and the provision of the anti-slip pattern can increase the friction with the patient's arm, thereby further improving the stability of the arm. BRIEF DESCRIPTION OF THE DRAWINGS

Since the bed is provided with a mattress and the patients have different body shapes, when the patient's arm is placed on the support plate body 100, the height of the arm may be higher or lower than the height of the torso. At this time, the height of the support plate body 100 can be adjusted by the lifting mechanism 200 so that the patient's arm can be at the same level as the torso. When the arm posture needs to be maintained for a long time, the patient's discomfort can be reduced and the convenience of operation for medical staff can be increased. Finally, the angle of the support plate body 100 can be adjusted by the positioning mechanism 400, and then the angle of the patient's arm can be adjusted, which helps to improve the accuracy and safety of the operation and improve the comfort of the patient.

When the patient's arm angle needs to be adjusted, the positioning rod 402 can be pulled downward to The positioning rod 402 drives its end to be pulled out from the socket 108, and drives the shoulder 403 to compress the spring 404. Then the support plate body 100 can be rotated to adjust its angle. When the angle is adjusted, the positioning rod 402 is released. At this time, the compressed spring 404 pushes the shoulder 403 to move upward, thereby driving the positioning rod 402 to move upward and reinsert into the socket 108, so that the support plate body 100 can be fixed at the current angle and the purpose of adjusting the patient's arm angle is achieved.

[0029] Specifically, a treatment tray 500 is installed at the end of the extended support plate 102. Through the arrangement of the treatment tray 500, puncture supplies can be placed, which is convenient for medical staff to take and use.
