Description

Technical Field

[0001] This utility model relates to the field of oral medical device technology, and in particular to a rapid head deflection angle measuring device. Background Technology

[0002] Oral cancer is the most common malignant tumor of the head and neck, and is mainly treated clinically with surgery. Because the defect is located in the oral-maxillofacial region, repair of the defect tissue is necessary simultaneously with tumor resection. Pedicled free tissue flap transfer has become a safe and effective tissue repair method; however, due to the need for intraoperative anastomosis of the vascular pedicle, postoperative vascular torsion and vascular crisis can easily occur, affecting flap survival and directly determining the success or failure of the repair surgery. Therefore, postoperative patient positioning management is particularly important.

[0003] Patients with oral cancer who undergo radical surgery and concurrent flap reconstruction typically require head immobilization for 72 hours. Postoperatively, depending on the intraoperative vascular anastomosis, patients should follow their doctor's instructions to immobilize their head in a neutral or lateral position upon returning to the ward. This is to prevent improper lateral head rotation, which could lead to flap vascular distortion and affect flap survival. Currently, clinical head immobilization relies primarily on the subjective judgment of medical staff; there is no rapid and precise method for angle assessment or measurement. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] To achieve the above objectives, this utility model proposes a rapid head deflection angle measuring device, including a headband mechanism and a color gamut angle display mechanism. The color gamut angle display mechanism is disposed on the headband mechanism and is used to measure the deflection angle of the patient's head. The headband mechanism includes a top headband and two sideburn bands, with two sideburn bands respectively disposed on both sides of the top headband. The color gamut angle display mechanism includes a housing, a dial, and a pointer assembly. The housing is disposed on the top headband, the dial is disposed inside the housing, and the pointer assembly is disposed on the dial.

[0006] Furthermore, the pointer assembly includes a center pointer and a counterweight, wherein the center pointer is rotatably positioned in the center of the dial, the counterweight is positioned at the bottom of the center pointer, and a pivot is provided between the center pointer and the counterweight.

[0007] Furthermore, a connecting seat is provided at the bottom of the outer shell, and a snap-fit ​​rod is provided on the top band, the snap-fit ​​rod being adapted to the connecting seat.

[0008] Furthermore, a hinge seat is provided at the bottom of the snap-fit ​​rod, and the bottom of the hinge seat is connected to the headband.

[0009] Furthermore, the headband has adjustment arms on both sides, the sideband has adjustment grooves that are compatible with the adjustment arms, the sideband has a headband length adjustment knob, and the surfaces of the headband and the sideband are both covered with flexible material.

[0010] Furthermore, the dial is provided with several indicator stickers, and a centerline positioning pointer is provided in the middle of the headband. The centerline positioning pointer is aligned with the 0° mark in the middle of the dial and the root of the patient's nose.

[0011] Beneficial effects: This utility model features a color gamut angle display mechanism on the headband. When in use, the patient lies flat and the headband is placed on the patient's head. When the patient's head turns at an angle, the pointer component deflects on the dial, allowing medical staff to intuitively observe the angle of the patient's head turn. This facilitates adjustment of the angle that needs to be braked on one side of the head, ensuring blood supply to the skin flap and promoting postoperative recovery.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The rapid head deflection angle measuring device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0020] like Figures 1-3 As shown, the rapid head deflection angle measuring device provided in this embodiment of the present invention includes a headband mechanism 2 and a color gamut angle display mechanism 1, wherein the color gamut angle display mechanism 1 is disposed on the headband mechanism 2 and is used to measure the deflection angle of the patient's head.

[0021] The headband mechanism 2 includes a top headband 21 and sidebands 23, wherein two sidebands 23 are provided, respectively located on both sides of the top headband 21.

[0022] The color gamut angle display mechanism 1 includes a housing 11, a dial 12, and a pointer assembly 13. The housing 11 is mounted on the headband 21, the dial 12 is mounted inside the housing 11, and the pointer assembly 13 is mounted on the dial 12.

[0023] Specifically, when patients who have undergone radical surgery for oral malignant tumors and concurrent flap transplantation return to their rooms after surgery, they should lie flat as instructed by the doctor. When the head needs to be turned to one side and requires angle immobilization, the medical staff should quickly put the headband 21 of the headband mechanism 2 on the center of the patient's forehead, and the sidebands 23 should be secured to the patient's temples. The extension line of the tail of the midline pointer 133 should be placed on the line connecting the tip and root of the nose. Then, the patient's head should be turned or the patient's head should be assisted to turn. When the midline pointer 133 points to the required angle on the dial 12, the patient's head should stop turning. Finally, the patient's head should be fixed on both sides with a saline bag, the device should be removed, cleaned, wiped and disinfected, and placed in a designated location.

[0024] In one embodiment of this utility model, such as Figure 3 As shown, the pointer assembly 13 includes a center pointer 133 and a counterweight 131. The center pointer 133 is rotatably positioned in the middle of the dial 12, and the counterweight 131 is positioned at the bottom of the center pointer 133. A pivot 132 is provided between the center pointer 133 and the counterweight 131.

[0025] Specifically, the counterweight 131 keeps the centerline pointer 133 vertically upward. After the patient's head deflects, it drives the entire rapid head deflection angle measuring device to deflect by a certain angle. The degree at which the centerline pointer 133 points to the dial 12 is the head deflection angle, ensuring the stability of the measurement.

[0026] In one embodiment of this utility model, such as Figure 3 As shown, a connecting seat 111 is provided at the bottom of the outer casing 11, and a snap-fit ​​rod 14 is provided on the headband 21. The snap-fit ​​rod 14 and the connecting seat 111 are mutually compatible. In use, the connecting seat 111 and the snap-fit ​​rod 14 can be plugged and unplugged to be used, which facilitates the separate use of the color gamut angle display mechanism 1 and the headband mechanism 2.

[0027] In one embodiment of this utility model, such as Figure 2 As shown, a hinge seat 15 is provided at the bottom of the snap rod 14. The bottom of the hinge seat 15 is connected to the headband 21 and can be used to adjust the angle on the vertical plane of the color gamut angle display mechanism 1. This allows for timely adjustment based on the supine position of different patients, facilitating the optimal angle display of the color gamut angle display mechanism 1.

[0028] In one embodiment of this utility model, such as Figure 2 As shown, the width of the sideburn band 23 is 5mm to 25mm. Adjustable arms 22 are provided on both sides of the headband 21. Adjustable grooves 25 are provided on the sideburn band 23. The adjustment grooves 25 and the adjustment arms 22 are adapted to each other. The headband length adjustment knob 27 is provided on the sideburn band 23. The surfaces of the headband 21 and the sideburn band 23 are provided with flexible material 24. The extension and retraction of the adjustment arms 22 can be adjusted according to the different head sizes of patients, thereby adjusting the clamping width of the sideburn band 23 to adapt to different head sizes. The flexible material 24 makes the headband 21 and the sideburn band 23 fit the patient's scalp better and reduces the pressure and irritation to the skin.

[0029] In one embodiment of this utility model, such as Figure 2 As shown, the dial 12 is equipped with several indicator stickers. The indicator stickers are divided into color gamuts and have sticker features, which are used by medical staff to intuitively obtain the angle of deflection that the patient's head needs to be adjusted. The centerline positioning pointer 26 is set in the middle of the headband 21. The centerline positioning pointer 26 is aligned with the 0° scale in the middle of the dial 12 and the root of the patient's nose, so as to align with the patient's bridge of the nose and make the centerline pointer 133 correspond to the center line of the patient's face.

[0030] Among them, color gamut division and sticker features:

[0031] In a preferred embodiment, in order to further enhance the visualization and comparison of the measurement results, the indicator sticker of this utility model divides the center scale of 0°, 15°, 30°, 45° and 60° into color gamuts within ±5° to the left and right, and marks them with different colors, so that users can quickly determine the angle range they are in by color.

[0032] Correspondingly, stickers in the same color gamut are provided, available in adhesive, removable, or disposable forms. Users can attach the corresponding stickers to additional reference objects or surfaces (such as the headboard of a hospital bed, a wall, or nearby medical equipment) to quickly compare and confirm the current color gamut range when measuring head deflection angles, thereby significantly improving the intuitiveness and convenience of the measurement.

[0033] Specifically, sticker colors may include:

[0034] 0°±5°: Red (hexadecimal color code: #FF0000) and light red (#FFCCCC);

[0035] 15°±5°: Dark orange (#FF7F00) and light orange (#FFBB80);

[0036] 30°±5°: Yellow (#FFFF00) and light yellow (#FFFFCC);

[0037] 45°±5°: Green (#008000) and light green (#CCFFCC);

[0038] 60°±5°: Blue (#0000FF) and light blue (#CCCCFF).

[0039] In addition, to help users understand the deflection angle more clearly, the sticker can be labeled with text information such as "center braking 0°", "left deflection ××°±5°" or "right deflection ××°±5°", which is convenient for quick identification.

[0040] To clearly illustrate the above embodiments, refer to Figures 1-3 The working principle of the rapid head deflection angle measuring device of this utility model is as follows: The color gamut angle display mechanism 1 provided by this utility model can be in the form of a 180° automatic protractor. When the patient's head deflects, the pointer of the midline pointer 133 can automatically point to the angle of deflection. In use, it is preferable to wear the retractable headband mechanism 2 on the forehead, and make the 0° angle scale line of the dial 12 and the line connecting the tip of the nose and the root of the nose in the same vertical plane, so as to determine the central reference position of the head. In a preferred embodiment, the indicator sticker in the dial 12 can also divide the center scales of 0°, 15°, 30°, 45°, 60°, etc. into different color gamuts within ±5° to the left and right respectively; at the same time, in order to further enhance the visualization and comparison effect of the measurement results, stickers corresponding to each color gamut can be provided separately. The user can stick the stickers on external reference objects such as mirrors, walls or auxiliary tools to quickly confirm the deflection angle range when observing or adjusting the head.

[0041] The bottom surface of the color gamut angle display mechanism 1 can be directly attached to the top surface of the retractable headband mechanism 2, or it can be installed via the connecting seat 111. The connecting seat 111 is a lightweight component (such as foam material) with a curved bottom and a flat top. This not only reduces the overall weight but also better matches the structural features of the retractable headband mechanism 2 and the color gamut angle display mechanism 1, ensuring a secure assembly and comfortable wearing.

[0042] Through the above design, the retractable headband mechanism 2 can adapt to different head circumferences of wearers, and the color gamut angle display mechanism 1 can clearly display the angle of the patient's head rotation, and can be quickly interpreted with the help of color gamut or sticker markings, meeting the clinical needs for precise control and management of the head rotation angle.

[0043] In summary, the rapid head deflection angle measuring device of this utility model, by setting a color gamut angle display mechanism on the headband mechanism, allows the patient to lie flat during use. By putting the headband on the patient's head, when the patient's head deflects, the pointer component deflects on the dial, so that medical staff can intuitively observe the angle of the patient's head deflection and easily adjust the angle that needs to be braked on the side of the head deflection.

[0044] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
