[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] In related techniques, novice medical staff often have difficulty directly grasping the size of the skin preparation area, leading to errors in the skin preparation area and consequently, poor surgical treatment results.

[0032] To improve the effectiveness of surgical treatment, refer to Figures 1 to 3 As shown, the periauricular skin preparation measuring ruler of this utility model includes: a support piece 100 and a measuring element 200. The support piece 100 is used to fit the human head and has an arc-shaped first side for measurement. The measuring element 200 includes a connecting part 210, a measuring part 220 and an abutting part 230. The connecting part 210 is connected to the support piece 100. At least a portion of the measuring part 220 extends out of the first side. The abutting part 230 is connected to the extended end of the measuring part 220 and is used to abut against the back of the ear.

[0033] In this embodiment, the support sheet 100 is a flexible sheet, allowing it to deform through its own flexibility and conform to the outer periphery of the human head. This enables the support sheet 100 to adapt to different patients' heads, improving patient comfort. Simultaneously, the support sheet 100 can be pre-formed into a curved surface with a certain curvature to generally conform to the heads of most patients and reduce its own deformation. This allows the support sheet 100 to be made of a material with a certain degree of plasticity, preventing it from being too soft and improving the user experience for medical staff. Alternatively, the support sheet 100 can also be a rigid sheet pre-formed to fit the shape of the patient's head.

[0034] The measuring piece 200 determines the distance between the first side and the abutment part 230 by a preset length. The area corresponding to this distance is the area where the patient needs to have the skin prepared. When using the periauricular skin preparation measuring ruler, medical staff can directly align the abutment part 230 with the back of the ear and then press the support piece 100 onto the outer periphery of the human head to divide the approximate periauricular skin preparation area. Medical staff can then directly prepare the skin in this area, making it more convenient for medical staff to operate and simpler to use.

[0035] Specifically, the measuring component 200 is connected to the support plate 100 via the connecting part 210. The connection method between the connecting part 210 and the support plate 100 includes bonding them together with glue, heat fusion, or other methods. The connection method between the connecting part 210 and the support plate 100 also includes detachable connection via fasteners such as bolts, or detachable connection via snap-fit.

[0036] The connecting part 210 and the measuring part 220 can also be integrally molded, bonded together with adhesive, heat-fused together, or connected together by other means. The connection methods for the connecting part 210 and the measuring part 220 also include detachable connection via bolts or other fasteners, or detachable connection via clips. When the connecting part 210 and the measuring part 220 are detachably connected, measuring parts 220 of different lengths can be replaced to meet the measurement needs of different patients. It should be noted that patients typically select an integer area or a decimal place after the decimal point for the skin preparation area; therefore, only a limited number of measuring parts 220 are needed to meet the usage requirements of most scenarios, making the measuring part 200 more convenient to use.

[0037] The measuring part 220 and the abutment part 230 can be integrally molded, glued together, heat-fused together, or connected in other ways. The connection methods between the measuring part 220 and the abutment part 230 also include detachable connection via bolts or other fasteners, or detachable connection via clips. When the measuring part 220 and the abutment part 230 are detachably connected, even if the measuring part 220 is replaced, the abutment part 230 does not need to be replaced, saving on the cost of the abutment part 230. Furthermore, different types of abutment parts 230 can be used to meet the measurement needs of different patients, thereby improving patient comfort.

[0038] It is understandable that when medical staff use it, they can directly attach the support plate 100 to the surface of the human head and use their fingers to press the support plate 100 to the surface of the human head for fixation. The abutment part 230 of the measuring part 200 abuts against the back of the human ear so that the distance between the first side and the abutment part 230 is exactly the measuring length corresponding to the measuring part 220. Medical staff can directly determine the skin preparation area by measuring the length, thereby improving the accuracy of the skin preparation area around the ear and improving the treatment effect.

[0039] Reference Figure 1 and Figure 3 As shown, in some specific embodiments of this utility model, the abutment portion 230 is similar in shape to the back of the ear to fit the back of the ear, so that the abutment portion 230 and the back of the ear can fit better and the pressure is evenly distributed, thereby improving the patient's comfort.

[0040] In this embodiment, the abutment portion 230 is arc-shaped, and the shape of the arc is basically consistent with the outline shape of the back of the ear. The distance from the first side of the support piece 100 to the back of the ear is basically consistent, so that the area between the support piece 100 and the abutment portion 230 is basically consistent in size, thereby improving the accuracy of the skin preparation area.

[0041] Reference Figure 1 and Figure 3 As shown, in some specific embodiments of this utility model, the support piece 100 includes a main piece portion 110 and a finger placement portion 120. The finger placement portion 120 is used to place human fingers. Medical staff can place their fingers directly in the finger placement portion 120 and press the support piece 100 on the patient's head, making it more convenient for medical staff to fix the support piece 100.

[0042] Reference Figure 1 As shown, in some specific embodiments of this utility model, the finger placement part 120 is a finger-shaped recess for placing the finger pad or a fingertip sleeve for placing the fingertip.

[0043] In this embodiment, the finger placement part 120 is a finger-shaped recess, and a friction layer may be provided inside the finger-shaped recess. Specifically, the friction layer may be multiple protrusions, multiple protrusions, or other structures that can increase friction, thereby increasing the friction between the fingertip and the finger-shaped recess. When medical staff apply external force to the support plate 100, it is not easy for the support plate 100 to slip off. Medical staff can better apply force to the support plate 100, so that the support plate 100 has a better fixation effect on the patient's head.

[0044] As another implementation, the finger placement part 120 is a fingertip sleeve. When medical staff use the periauricular skin preparation measuring ruler, they insert their fingertips into the fingertip sleeve. The fingertip sleeve fixes the medical staff's fingertips and the support plate 100. The medical staff then fixes the support plate 100 to the patient's head. The fingers and the support plate 100 are less likely to slip relative to each other, making it easier for medical staff to fix the support plate 100.

[0045] In some specific embodiments of this utility model, the finger placement part 120 is a flexible part.

[0046] In this embodiment, when the finger placement part 120 is a finger-shaped recess, the flexible finger-shaped recess can provide a better feel. When the finger-shaped recess is subjected to external force, it also undergoes elastic deformation. The deformed finger-shaped recess fits more closely with the fingertips of medical staff, improving the effectiveness of use for medical staff. At the same time, the pressure applied by medical staff can be partially absorbed by the elasticity of the finger-shaped recess itself, so as to avoid the local pressure applied by medical staff to the support plate 100 being transmitted to the human head, thereby avoiding the patient's head being squeezed by local stress and feeling pain, and improving the patient's comfort.

[0047] As another implementation, when the finger placement part 120 is a fingertip sleeve, the flexible fingertip sleeve can adapt to the size of different fingers through its own elasticity, making the adaptation range of the fingertip sleeve wider. In addition, the fingertip sleeve fits more closely with the fingertips of medical staff, allowing medical staff to better control the support plate 100 to contact the patient's head, making it more convenient for medical staff to use. At the same time, the pressure applied by medical staff can be partially absorbed by the elasticity of the finger-shaped indentation itself, so as to avoid the local pressure applied by medical staff to the support plate 100 being transmitted to the human head, thereby avoiding the patient's head being squeezed by local stress and feeling pain, and improving the patient's comfort.

[0048] Reference Figure 1 and Figure 3 As shown, in some specific embodiments of this utility model, the support piece 100 includes five finger placement portions 120.

[0049] In this embodiment, medical personnel typically use one hand to press the support plate 100 and then use the other hand to shave hair. Therefore, providing five finger placement portions 120 can meet the needs of medical personnel. The five fingers are spaced apart sequentially along the length of the first side of the support plate 100 to secure the support plate 100 as a whole. Alternatively, the finger placement portions 120 can be one, two, three, or four.

[0050] In addition, the measuring unit 220 will form a shield in the shaving area, but after the hair in other parts of the shaving area is shaved, only the area corresponding to the measuring unit 220 still has hair. At this time, the hair in the shaving area can be shaved according to the shaving range of other parts of the shaving area.

[0051] In some specific embodiments of this utility model, the length of the measuring part 220 is 4mm to 6mm. Further, the length of the measuring part 220 is 5mm.

[0052] Generally speaking, the size of the skin preparation area is about 5mm, so a 5mm length for the measuring section 220 is sufficient to meet the usage requirements and make it more convenient to use.

[0053] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some specific embodiments of this utility model, the measuring member 200 further includes a rotating part 240 disposed between the connecting part 210 and the measuring part 220, and the measuring part 220 further includes a first position and a second position; wherein, the measuring part 220 is configured such that: in the first position, the measuring part 220 overlaps with the support piece 100; in the second position, the measuring part 220 extends out of the first side.

[0054] It is worth understanding that the measuring part 220 can be rotated by the rotating part 240 to coincide with the support piece 100, thereby making the measuring part 220 and the support piece 100 overlap in space. The periauricular skin preparation measuring ruler occupies less space, which makes it easier to store and use, and makes it more convenient for medical staff.

[0055] In this embodiment, the rotating part 240 is a rotating shaft, the connecting part 210 has a first connecting end, and the measuring part 220 has a second connecting end. The first connecting end has a first shaft hole, and the second connecting end has a second shaft hole. The first shaft hole and the second shaft hole are aligned along the axial direction. The rotating shaft passes through the first shaft hole and the second shaft hole, thereby realizing the rotational connection between the connecting part 210 and the measuring part 220.

[0056] Furthermore, when the measuring unit 220 forms an obstruction in the skin preparation area, the measuring unit 220 can be rotated to the area where the support plate 100 is located by the rotating unit 240, thereby eliminating the influence of the measuring unit 220.

[0057] Reference Figure 1 and Figure 3 As shown, in some specific embodiments of this utility model, the measuring part 220 has a first magnetic element 221, and the support sheet 100 has a second magnetic element 130 and a third magnetic element 140; wherein, the measuring part 220 is configured such that: in a first position, the first magnetic element 221 is magnetically connected to the second magnetic element 130; and in a second position, the first magnetic element 221 is magnetically connected to the third magnetic element 140.

[0058] It is worth understanding that when the measuring part 220 rotates to overlap with the support plate 100, the magnetic attraction of the first magnetic element 221 and the second magnetic element 130 achieves relative fixation between the measuring part 220 and the support plate 100, thereby improving the stability of the measuring part 220 in the first position. This makes it less likely for the measuring part 220 to separate from the support plate 100 in the first position, thus avoiding trouble and repetitive overlapping work, and making it more convenient for medical staff to store it.

[0059] In this embodiment, a portion of the measuring section 220 extends from the first side, and another portion is aligned with the support plate 100 at a second position. The other portion of the measuring section 220 has a first magnetic element 221, which extends through both opposite sides of the measuring section 220. In the first position, the first magnetic element 221 on one side is magnetically attracted to a second magnetic element 130 on the support plate 100. In the second position, the second magnetic element 130 on the other opposite side is magnetically attracted to a third magnetic element 140 on the support plate 100. Specifically, the magnetic attraction can be between two magnets or between a magnet and iron.

[0060] In another embodiment, the measuring unit 220 may include a first magnetic element 221 and a fourth magnetic element, and the support sheet 100 has a second magnetic element 130 and a third magnetic element 140; wherein the measuring unit 220 is configured such that: in a first position, the first magnetic element 221 is magnetically connected to the second magnetic element 130; and in a second position, the fourth magnetic element is magnetically connected to the third magnetic element 140.

[0061] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
