[0002] The heart is a vital organ in the human body. Following cardiac surgery, appropriate nursing care is necessary, including constant monitoring of the patient's vital signs and timely dressing changes at the wound site, to aid in recovery. During vital sign monitoring, instrument fixation devices are required to ensure stable placement of the relevant equipment.

[0003] Chinese utility model patent CN210043997U discloses a fixing device for a cardiac surgery nursing examination instrument. By setting up a placement frame, the electrocardiogram monitor can be fixed on the placement frame with the help of casters, without occupying the patient's bed and bedside table, and the device can be moved easily. By setting up a transparent glass and using a concealed lock, the electrocardiogram monitor can be locked inside the placement box, effectively preventing unauthorized personnel from operating the device and allowing easy viewing of the device. By setting up a winding tube, the various cables of the electrocardiogram monitor can be wound around the outside of the winding tube one by one.

[0004] A search revealed that the fixation devices proposed in the aforementioned comparative documents have a constant height, cannot be adjusted according to actual needs, and the instrument is directly locked inside the placement box without a positioning structure. During movement, the instrument is prone to collision with the placement box, leading to damage. Therefore, there is an urgent need to improve the existing fixation devices for cardiac surgery nursing examination instruments and provide a new fixation device for cardiac surgery nursing examination instruments.

[0018] Example 1, see Figure 1-6As shown, a cardiac surgical nursing examination instrument fixing device includes a movable base 1 and an electrocardiogram (ECG) monitor 6. A height control component 2 is fixed to the upper rear of the movable base 1. A tray 4 is fixedly installed on the outer side of the top of the height control component 2. A base plate 7 is fixedly installed at the bottom of the ECG monitor 6. The base plate 7 is snapped into the inner side of the front end of the tray 4. The front end of the tray 4 has symmetrically opened through grooves 8. Positioning components 9 are installed in both through grooves 8. A vertical shaft 10 is installed on the bottom end face of the tray 4 through a spiral spring 11. A disc 12 is fixedly sleeved on the outer side of the middle part of the vertical shaft 10. An arc-shaped groove 13 is opened inside the disc 12. There are two arc-shaped grooves 13, which are symmetrical about the center point of the disc 12.

[0019] In Example 2, the height control component 2 includes an inner rod 21, a slide groove 22, an outer rod 23, a trapezoidal lead screw 24, and rollers 25. The inner rod 21 is fixedly installed at the upper rear center of the movable base 1. Slide grooves 22 are provided on the outer walls of both the left and right sides of the inner rod 21. The outer rod 23 is slidably sleeved on the outer side of the inner rod 21. The trapezoidal lead screw 24 is mounted on the bearing in the middle of the outer rod 23. The trapezoidal lead screw 24 is threadedly connected to the inner rod 21. Rollers 25 are rotatably installed on the inner walls of both the left and right sides of the bottom end of the outer rod 23. The two rollers 25 are respectively guided and slidably located in the two slide grooves 22.

[0020] In this embodiment, by controlling the rotation of the trapezoidal lead screw 24, it is convenient to control the outer rod 23 to be raised and lowered outside the inner rod 21, thereby facilitating the adjustment of the device height and the positioning height of the electrocardiogram monitor 6 as needed.

[0021] In Example 3, the top end of the outer rod 23 is fixedly connected to the tray 4 and a diagonal brace 5 is fixedly installed between the two. The diagonal brace 5, the outer rod 23 and the tray 4 are distributed in a triangular structure. A positioning bolt 3 is threaded on the outer wall behind the top end of the outer rod 23.

[0022] In this embodiment, the diagonal brace 5 is used to reinforce and support the tray 4, and the trapezoidal screw 24 is positioned by tightening the positioning bolt 3.

[0023] In Example 4, the positioning component 9 includes a crossbar 91, a limiting block 92, and a fixing post 93. The crossbar 91 is fixedly installed in the middle of the inner side of the through groove 8. The limiting block 92 is slidably sleeved on the outer side of the crossbar 91. The vertical section of the limiting block 92 is engaged and slidably located in the through groove 8, and the bottom of the vertical section of the limiting block 92 is fixedly connected to the fixing post 93.

[0024] In Example 5, the bottom guide slide of the fixed column 93 is located in the arc groove 13, the two limiting blocks 92 are linked by the disc 12, and the sliding directions of the two limiting blocks 92 are always opposite.

[0025] In Example 6, the limiting block 92 and the base plate 7 form a snap-fit ​​installation and disassembly structure.

[0026] In this embodiment, by controlling the rotation of the disc 12, the arc groove 13 inside the disc 12 facilitates the squeezing and pushing of the fixed column 93, thereby controlling the two limit blocks 92 to slide synchronously in opposite directions, which facilitates the installation and disassembly of the ECG monitor 6.

[0027] Working principle: In use, first hold the vertical shaft 10 and control it to drive the disc 12 to rotate. Use the arc groove 13 inside the disc 12 to squeeze the fixing column 93, thereby pushing the two left and right limit blocks 92 to slide synchronously along the horizontal bar 91 and move away from each other. Then, snap the bottom plate 7 of the ECG monitor 6 into place on the inner front end of the tray 4. Then release the vertical shaft 10. At this time, the vertical shaft 10 and the disc 12 can be rotated by the spiral spring 11, which can make the two limit blocks 92 slide back and reset and stably snap into place with the bottom plate 7, thus achieving a stable positioning and installation of the ECG monitor 6. Similarly, it is also convenient to quickly disassemble the ECG monitor 6, making the operation convenient. After the ECG monitor 6 is positioned and installed, the device can be pushed to the side of the patient's bed. Then, the trapezoidal screw 24 can be manually rotated to control the vertical lifting and lowering of the outer rod 23 along the inner rod 21. The sliding grooves 22 on the outer walls of the left and right sides of the inner rod 21 and the rollers 25 mounted on the inner walls of the left and right sides of the bottom of the outer rod 23 can improve the lifting and lowering stability of the outer rod 23. The sliding grooves 22 and rollers 25 can also limit the lifting and lowering range of the outer rod 23, enabling quick adjustment of the device height and facilitating the adjustment of the fixed height of the ECG monitor 6 as needed. The trapezoidal screw 24 has a self-locking function, and the positioning bolts 3 can be tightened to achieve a resisting positioning effect on the trapezoidal screw 24, ensuring the stability of the device height adjustment.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
