Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an adjustable hand support plate across the chest. Background Art

[0002] Before the operation, various operations need to be performed on the patient's hands according to requirements, such as venipuncture and blood pressure measurement. In order to facilitate medical staff to operate on the patient's hands, detachable hand supports are set on both sides of the operating table.

[0003] After searching, a radial artery puncture hand support board with announcement number CN211271029U includes a base, a hand buckle is provided at one end of the base, a connecting belt is fixedly connected to one side of the base, an adhesive strip is fixedly connected to the other side of the base, an adhesive burr is fixedly connected to the end of the connecting belt away from the base, and a hand support groove is provided on the upper surface of the base. The radial artery puncture hand support board is provided with a hand support pad and a thermal insulation pad. The hand support pad is made of artificial leather, which is soft and comfortable. The thermal insulation pad can effectively slow down the rate of body temperature loss and increase comfort. Through the provision of the hand buckle and the stabilizing device, the palm needs to be turned outward and pressed down outward during radial artery puncture. It is very uncomfortable to maintain it for a long time. If the palm is in a fist-like posture, it may cause the needle to puncture the blood vessel, and the hand buckle can prevent the wrist from lifting up. The patient's arm is placed in the hand support groove. When the arm is pressed down, the stabilizing device can allow the patient to ensure the position of the arm;

[0004] Based on the above patent, the provision of the hand buckle and the stabilizing device can prevent medical accidents caused by squeezing the needle with a fist. When puncturing the radial artery, the palm needs to be turned outward and pressed down outward for a long time, which is very uncomfortable. If the palm is in a clenched fist and raised posture, the needle may puncture the blood vessel, and the hand buckle can prevent the wrist from being lifted up. The patient's arm is placed in the hand support groove. When the arm is pressed down, the stabilizing device can allow the patient to experience the squeezing feeling and know the position of his arm. The patient can adjust the downward pressure of his arm according to the squeezing feeling to ensure the position of the arm. However, the overall structure of the device is fixed. When the length of the patient's arm is greater than or less than the length of the hand support board, the patient's arm will be suspended in the air or squeezed by the hand support board, feeling uncomfortable, which can easily cause the patient to move abnormally and affect the doctor's operation.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-3 An embodiment of the utility model provides: an adjustable cross-chest hand support board, including a base 2 4, a soft pad 3 is fixedly connected to the top of the base 2 4, two fixed blocks 13 are fixedly connected to the left and right sides of the rear end of the base 2 4, the top of the fixed block 13 is fixedly connected to a fixing belt 6, the other end of the fixing belt 6 is fixedly connected to a clamping block 15, the inner wall of the clamping block 15 is connected to the limited block 5 through a spring 17, one end of the two springs 17 is fixedly connected to the inner wall of the clamping block 15, the other ends of the two springs 17 are fixedly connected to the rear end of the limit block 15, the outer wall of the clamping block 15 is provided with a buckle 2, the rear ends of the two buckles 2 are fixedly connected to the front end of the base 2 4, and the outer walls of the two limit blocks 15 are slidably connected Connected to the inner wall of the card block 15, the outer walls of the two limit blocks 15 are both set on the inner wall of the buckle 2, the base 24 is slidably connected with a slide rod 16, the right end of the slide rod 16 is fixedly connected to the limit block 214, the limit block 214 is slidably connected to the inner wall of the base 24, the left side of the outer wall of the slide rod 16 is fixedly connected to the base 1, the inner wall of the base 1 is rotatably connected with a threaded rod 12, the left end of the threaded rod 12 is fixedly connected with a rotating block 8, the right side of the outer wall of the threaded rod 12 is threadedly connected to the inner wall of the base 24, the top of the base 1 is fixedly connected with a cushion 27, the outward end of the base 1 is fixedly connected with two rotating shafts 11, the outer wall of the rotating shaft 11 is rotatably connected with a connecting block 10, and the top of the connecting block 10 is fixedly connected with a hand buckle 9;

[0024] Specifically, the patient's arm is placed on the base 2 4, and the threaded rod 12 is driven to rotate by turning the rotary block 8, so that the base 1 is away from the base 2 4 with the cooperation of the slide bar 16, and the distance between the base 1 and the base 2 4 is adjusted according to the length of the patient's arm, so that the patient's arm is completely on the device, and will not be suspended in the air or squeezed by the device to cause discomfort and affect the doctor's operation.
