Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a finger fixing and clamping device. Background Art

[0002] ICU stands for Intensive Care Unit, where treatment, nursing and rehabilitation can be carried out simultaneously, providing isolation space and equipment for critically ill or comatose patients. Electrocardiogram is a commonly used instrument in ICU wards to monitor the patient's heart rate, and the electrocardiogram often monitors by clamping the patient's finger with a finger clamp.

[0003] The utility model with authorization announcement number CN213372040U provides an electrocardiograph finger clamping device for ICU patients. When clamping the finger, it can measure the clamping force to the set value and provide a prompt, keeping the force within the appropriate clamping range and improving clamping comfort.

[0004] However, in the above patent, in the process of pressing the upper clamping box toward the lower clamping box so that the two snap springs are vertically inserted into the two grooves respectively, the upper clamping box may be skewed due to uneven pressing force, resulting in different depths of the two snap springs inserted into the two grooves, and the two snap hooks are clamped into two snap grooves at different heights. When the upper clamping box in a skewed state is clamped and fixed on the patient's finger in conjunction with the lower clamping box, the upper clamping box and the lower clamping box exert uneven squeezing force on various parts of the patient's finger, which may easily make the patient's finger feel uncomfortable. In view of this, we propose a finger fixing clamping device. Summary of the Invention

[0008] As a further improvement of the present technical solution, a hook is fixedly connected to a position near the lower end of one side of the elastic plate, and a number of upper slots are provided in a vertical array on the inner wall of the slot. The hook and the upper slot are located on the same side of the elastic plate. After the elastic plate is inserted into the slot, a gap is formed between the side of the elastic plate away from the hook and the inner wall of the slot.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0028] See also Figure 1-Figure 7As shown, this embodiment provides a finger fixing clamping device, including a lower clamping box 1, a bracket 2 is slidably arranged inside the lower clamping box 1, two first springs 3 are fixedly connected between the lower surface of the bracket 2 and the bottom surface of the lower clamping box 1, and two vertical rods are fixedly connected between the top surface and the bottom surface of the lower clamping box 1. The vertical rods are arranged vertically, and the horizontal section of the bracket 2 is slidably sleeved on the outside of the two vertical rods. The first spring 3 is sleeved on the outside of the vertical rods. The vertical rods limit the bracket 2 to only vertical up and down movement. When the bracket 2 moves vertically downward, the first spring 3 When the first spring 3 elastically contracts and rebounds, the bracket 2 is lifted upward, and a slot 4 is symmetrically provided on the top of the lower clamping box 1. The slot 4 is connected to the interior of the lower clamping box 1. The bracket 2 is a U-shaped structure. The two vertical sections of the bracket 2 are respectively slidably arranged in the two slots 4. The vertical sections of the bracket 2 fit tightly with the inner walls of the slots 4, further limiting the stability of the vertical movement of the bracket 2 in the lower clamping box 1. A locking mechanism 5 is symmetrically provided on the bracket 2. The locking mechanism 5 limits the position of the vertical section of the bracket 2 in the slot 4, so that the bracket 2 cannot move vertically. An upper clamping box 6 is provided above the lower clamping box 1. Elastic plates 71 are symmetrically provided at the bottom of the upper clamping box 6 near both sides. When the upper clamping box 6 is moved vertically toward the lower clamping box 1, the two elastic plates 71 are respectively inserted into the two slots 4, and then the two elastic plates 71 press the two locking mechanisms 5 downward respectively, releasing the restrictions of the two locking mechanisms 5 on the position of the bracket 2, so that the bracket 2 can move vertically downward. When the two elastic plates 71 press the bracket 2 downward, the upper clamping box 6 is clamped and fixed with the lower clamping box 1, and the bracket 2 can be further clamped. The upper clamping box 6 moves vertically toward the lower clamping box 1, causing the bracket 2 under pressure to move downward. The top of the lower clamping box 1 is fixedly connected to an electrode touch plate 8 between the two slots 4. The electrode touch plate 8 is electrically connected to an external electrocardiograph. After the patient places his finger between the lower clamping box 1 and the upper clamping box 6 to contact the electrode touch plate 8, the distance between the upper clamping box 6 and the lower clamping box 1 is adjusted so that the upper clamping box 6 and the lower clamping box 1 are clamped and fixed on the patient's finger, which makes it convenient to use the electrocardiograph to monitor the patient's heart rate.

[0029] Reference Figure 4The cam 72 is fixedly connected to the lower end of one side of the elastic plate 71, and a plurality of upper slots 73 are vertically arranged in an array on the inner wall of the slot 4. The hook 72 and the upper slot 73 are located on the same side of the elastic plate 71. After the elastic plate 71 is inserted into the slot 4, a gap is formed between the side of the elastic plate 71 away from the hook 72 and the inner wall of the slot 4. When the two elastic plates 71 are vertically inserted downward into the two slots 4, the inclined side of the hook 72 contacts the inner wall of the slot 4, and the inner wall of the slot 4 presses the hook 72 and the elastic plate 7 1 is squeezed toward the electrode contact plate 8, and the elastic plate 71 undergoes elastic deformation. When the elastic plate 71 drives the hook 72 to squeeze into the interior of the slot 4, the rebound force of the elastic plate 71 causes the hook 72 to squeeze the side of the slot 4 away from the electrode contact plate 8. After the elastic plate 71 presses the locking mechanism 5 downward and releases the locking mechanism 5 from limiting the bracket 2, in order to clamp and fix the upper clamping box 6 and the lower clamping box 1, the upper clamping box 6 and the lower clamping box 1 are clamped and fixed on fingers of different sizes to perform heart rate monitoring on patients of different body shapes.

[0030] Reference Figure 4 The locking mechanism 5 includes a mounting cavity 51 provided inside the bracket 2, and a vertical plate 52 is slidingly provided on the inner wall of the mounting cavity 51. The vertical plate 52 is vertically arranged, and the upper end of the vertical plate 52 passes through the mounting cavity 51 and extends to the top of the bracket 2. A horizontal plate 54 is slidingly provided on the bottom surface of the mounting cavity 51, and the horizontal plate 54 is horizontally arranged. A second spring 55 is fixedly connected between one end of the horizontal plate 54 and the inner wall of the mounting cavity 51. A slide is provided inside the horizontal plate 54, and a guide rod is slidingly provided on the inner wall of the slide. The end of the guide rod away from the lower card slot 11 is fixedly connected to the inner wall of the mounting cavity 51, so that the horizontal plate 54 can only move horizontally along the outer wall of the guide rod. The second spring 55 is sleeved on the outer side of the guide rod, and the other end of the horizontal plate 54 passes through the side wall of the bracket 2 and extends to the outside of the bracket 2 The bottom of the vertical plate 52 is hinged with a connecting rod 53, which is set at an angle. The lower end of the connecting rod 53 is hinged to the top of the cross plate 54. A number of lower card slots 11 are provided in the vertical array on the inner wall of the lower clamping box 1. One end of the cross plate 54 away from the second spring 55 is slidably set inside one of the lower card slots 11. The lower card slot 11 limits the vertical movement of the cross plate 54, thereby preventing the bracket 2 from moving vertically. After the elastic plate 71 contacts the upper end of the vertical plate 52, the elastic plate 71 continues to move downward, which will drive the vertical plate 52 to move downward synchronously. The downward moving vertical plate 52 squeezes the connecting rod 53. After one end of the connecting rod 53 is subjected to downward pressure, the connecting rod 53 drives the cross plate 54 to move horizontally in the direction away from the lower card slot 11, and the second spring 55 elastically contracts. Figure 7As shown, when the elastic plate 71 presses the vertical plate 52 to a position on the same horizontal plane as the upper end surface of the bracket 2, one end of the horizontal plate 54 moves out from the inside of the lower slot 11, releasing the limit of the bracket 2 by the locking mechanism 5. At this time, the bracket 2 can move vertically downward to adjust the distance between the upper clamping box 6 and the lower clamping box 1, so that the upper clamping box 6 and the lower clamping box 1 are clamped and fixed on the patient's fingers, so that the electrode touch plate 8 can monitor the heart rate.

[0031] When the locking cam 72 is in the closed position, the locking cam 72 is in the closed position, and the spring 72 is in the closed position, so that the winch 72 can be locked.

[0032] When the clamping box 72 moves downward to the other side of the upper clamping slot 73, the elastic plate 71 rebounds to make the hook 72 clamp the upper clamping slot 73, and so on. When the upper clamping box 6 is pressed in the direction close to the lower clamping box 1, the adjustment is carried out. When the distance between the upper clamping box 6 and the lower clamping box 1 is adjusted, the hook 72 will be sequentially inserted into different upper clamping slots 73 from top to bottom, and the upper clamping box 6 and the lower clamping box 1 can be clamped and fixed by the hook 72 being inserted into any upper clamping slot 73. The bottom of the upper clamping box 6 is located between the two elastic plates 71 and is fixedly connected with a buffer pad 9. The buffer pad 9 is located directly above the electrode contact plate 8. When the distance between the upper clamping box 6 and the lower clamping box 1 is adjusted so that the upper clamping box 6 and the lower clamping box 1 are clamped and fixed on the patient's finger, the buffer pad 9 elastically deforms after contacting the finger, which makes it convenient to adjust the squeezing force of the upper clamping box 6 and the lower clamping box 1 on the patient's finger. When the patient feels comfortable, the hook 72 is inserted into the nearest upper clamping slot 73 to improve the patient's comfort during electrocardiogram monitoring.

[0033] When the medical staff presses the upper clamping box 6 toward the lower clamping box 1, so that the two elastic plates 71 push the bracket 2 to move vertically downward, if the upper clamping box 6 tilts due to uneven force, one of the elastic plates 71 will not be able to press the vertical plate 52 below it downward into place, that is, the elastic plate 71 cannot contact the upper surface of the bracket 2, and the horizontal plate 54 below the vertical plate 52 will be pushed toward the lower slot 11 by the rebounding second spring 55 until it is stuck in the nearest slot below it. Inside the lower card slot 11, the horizontal plate 54 blocks the upper clamping box 6 from moving toward the lower clamping box 1, thereby reminding medical staff to adjust the posture of the upper clamping box 6 so that the upper clamping box 6 remains parallel to the lower clamping box 1, so that when the upper clamping box 6 and the lower clamping box 1 are clamped and fixed on the patient's fingers, the upper clamping box 6 and the lower clamping box 1 are in a state of vertical parallelism, so that the upper clamping box 6 and the lower clamping box 1 exert uniform squeezing force on various parts of the patient's fingers, ensuring that the patient's fingers are in a comfortable state.

[0034] When the electrocardiogram monitoring is finished and the upper clamping box 6 and the lower clamping box 1 need to be removed from the patient's finger, the two elastic plates 71 are pressed in the direction approaching each other, so that the two elastic plates 71 are elastically deformed, driving the hooks 72 to move out from the inside of the upper clamping slots 73, and the elastic plates 71 can be pulled out from the slots 4, and the upper clamping box 6 and the lower clamping box 1 are separated and removed from the patient's finger. To facilitate the medical staff to press the two elastic plates 71 in the direction approaching each other, side windows 74 are symmetrically provided on both sides of the lower clamping box 1 near the top, and the side windows 74 are connected to the inside of the slot 4. The medical staff puts their fingers into contact with the position near the lower end of one side of the elastic plate 71 through the side windows 74, and can press the two elastic plates 71 in the direction approaching each other with less effort, making it convenient to remove the upper clamping box 6 and the lower clamping box 1 from the patient's finger.
