[0039] See also Figures 1 to 8 In an embodiment of the present invention, an adjustable postoperative peri-auricular pressure device comprises a head-mounted body 1, and a connecting block 101 fixedly mounted on the head-mounted body 1;

[0040] The head-mounted body 1 is provided with an adjustment block 2, and the adjustment block 2 is connected to the connection block 101 through a fitting mechanism; and the distance between the adjustment block 2 and the head-mounted body 1 can be increased or decreased through the fitting mechanism;

[0041] The adjusting block 2 is rotatably provided with a connecting plate 4, and a mounting plate 5 is fixedly mounted on the connecting plate 4; a pressure block 6 is provided on the mounting plate 5, and a vertical control block 7 is provided on the pressure block 6; and an ear pad 8 is provided on the vertical control block 7;

[0042] A position adjustment mechanism is provided on the mounting plate 5, and the position adjustment mechanism can drive the vertical control block 7 to move on the pressure block 6 to change the vertical position of the ear pad 8; and can drive the ear pad 8 to move on the vertical control block 7 to change the horizontal position of the ear pad 8;

[0043] The mounting plate 5 is provided with a pressurizing mechanism, and the pressurizing mechanism can drive the pressurizing block 6 away from or close to the mounting plate 5;

[0044] The mounting plate 5 is also provided with a control button 505 for controlling the actions of the pressurizing mechanism and the position adjusting mechanism.

[0045] Taking the embodiment of the combination of all the features recorded in this application as an example, when in use, the ear pad 8 is in a "V-shaped" shape, adapted to the shape of the human ear, and is divided into a pre-ear pressure zone and a post-ear pressure zone. The pre-ear pressure zone is in a rounded quadrilateral shape, covering the temporomandibular joint and parotid gland area, and the pressure zone is in an oblate spherical shape, adapted to the concave shape behind the ear. The ear pad 8 has a sponge pad on the skin side, which is disposable and detachable to effectively avoid cross infection. It has a heating function, and the heating temperature is controlled by the control button 505. Hot compress after surgery is beneficial to reduce swelling.

[0046] After the operation, the patient can lie on the bed and connect the periauricular pressurizing device through an external power supply, or the pressurizing mechanism and the position adjusting mechanism can be driven by the power supply installed in the mounting plate 5, so that the device can be used in various environments.

[0047] The control button 505 is connected to the control system, and when it is actuated, it can drive the position adjustment mechanism and the pressurizing mechanism to actuate through the control system.

[0048] First, the ear pad 8 is covered around the patient's ear, and the vertical control block 7 is driven to move on the pressure block 6 through the position adjustment mechanism, and the ear pad 8 is driven to move on the vertical control block 7, so as to adjust the position of the ear pad 8 so that each pressure zone can correspond to the affected area, thereby improving the application range of the device.

[0049] The pressure blocks 6 are driven toward the ear pads 8 by the pressure mechanisms on the left and right sides respectively, so as to increase the squeezing force of the ear pads 8 on the patient, until the squeezing force on the left and right sides can meet the squeezing requirement of the affected part and is within the patient's tolerance range; in this way, the pressure is adjusted to avoid postoperative complications, reduce the patient's pain in the surgical area, and improve comfort.

[0050] Then, the distance between the head-mounted body 1 and the adjustment block 2 is adjusted through the fitting mechanism until the head-mounted body 1 contacts the top of the patient's head, and the stability of the pressure of the ear pad 8 on the affected part is improved by supporting the head-mounted body 1 with the top of the patient's head.

[0051] In another embodiment of the present invention, the fitting mechanism includes a tooth groove 102 provided in the connecting block 101 ; a contraction seam 201 is provided on the adjusting block 2 , and a protruding block 202 engaged with the tooth groove 102 is fixedly mounted on the adjusting block 2 .

[0052] Taking the embodiment combining all the features recorded in this application as an example, when in use, when an external force is applied to the adjustment block 2 to move in the direction of the head-mounted body 1, the adjustment block 2 will move inward in the tooth groove 102. During the movement, the inner wall of the tooth groove 102 will squeeze the protruding block 202, so that the protruding blocks 202 on both sides are close to each other, thereby reducing the gap spacing of the contraction seam 201, so that the adjustment block 2 can move smoothly in the tooth groove 102. After the head-mounted body 1 contacts the top of the patient's head, the inner wall of the tooth groove 102 will bite into the protruding block 202, thereby increasing the difficulty of the adjustment block 2 moving outward in the tooth groove 102, thereby improving the stability of the ear pad 8 squeezing the patient's affected part.

[0053] In another embodiment of the present invention, the protruding block 202 is triangular in shape, and the slope of a side close to the head-mounted body 1 is smaller than the slope of a side away from the head-mounted body 1 .

[0054] Taking the embodiment combining all the features described in the present application as an example, when in use, the side of the protruding block 202 that slides toward the adjusting block 2 into the tooth groove 102 has a slope, which reduces the resistance of the tooth groove 102 to the movement of the protruding block 202 along with the adjusting block 2, thereby reducing the difficulty of operating the fitting mechanism; and the side of the protruding block 202 that slides away from the adjusting block 2 into the tooth groove 102 has a steeper slope, which can increase the resistance of the tooth groove 102 to the outward movement of the protruding block 202 along with the adjusting block 2, thereby improving the stability of the fitting mechanism, thereby improving the stability of the ear pad 8 squeezing the patient's affected area.

[0055] According to another embodiment of the present invention, the position adjustment mechanism includes a vertical slide groove 601 provided on the pressure block 6, a vertical screw rod 602 is rotatably installed in the vertical slide groove 601, and a vertical internal threaded sleeve 703 threadedly connected to the vertical screw rod 602 is fixedly installed on the vertical control block 7; a horizontal slide groove 701 is provided on the vertical control block 7, a horizontal screw rod 702 is rotatably installed in the horizontal slide groove 701, and a horizontal internal threaded sleeve 801 threadedly connected to the horizontal screw rod 702 is fixedly installed on the ear pad 8.

[0056] Taking the embodiment combining all the features described in the present application as an example, when in use, after the ear pad 8 contacts the patient's ear, the position adjustment mechanism is controlled by the control button 505 to control the position of the ear pad 8.

[0057] First, the vertical screw rod 602 is driven to rotate so that the vertical screw rod 602 and the vertical internal threaded sleeve 703 are threadedly engaged, so that the vertical control block 7 slides vertically on the pressure block 6, thereby changing the vertical position of the ear pad 8; then the transverse screw rod 702 is driven to rotate, and the transverse internal threaded sleeve 801 is driven to move in the transverse direction of the vertical control block 7 through thread engagement, thereby changing the transverse position of the ear pad 8; each pressure zone can correspond to the affected area, thereby improving the application range of the device.

[0058] According to another embodiment of the present invention, the pressurizing mechanism includes a pressurizing groove 501 opened on the mounting plate 5, and the pressurizing groove 501 is slidably engaged with the pressurizing block 6; a pressurizing screw 603 is fixedly mounted on the pressurizing block 6, and a pressurizing internal threaded sleeve 502 threadedly connected to the pressurizing screw 603 is rotatably mounted on the mounting plate 5, a first gear 503 is fixedly mounted on the pressurizing internal threaded sleeve 502, and a second gear 504 meshing with the first gear 503 is rotatably mounted on the mounting plate 5.

[0059] Taking the embodiment combining all the features described in the present application as an example, when in use, after the position of the ear pad 8 is adjusted, the pressure mechanism is driven by the control button 505 to increase the squeezing force of the ear pad 8 on the patient's ear area.

[0060] The second gear 504 is driven to rotate, and the first gear 503 is driven to rotate through its meshing action with the first gear 503, thereby driving the pressurizing internal threaded sleeve 502 to rotate, and the pressurizing screw 603 is driven to move toward the pressurizing groove 501 through the thread cooperation between the pressurizing internal threaded sleeve 502 and the pressurizing screw 603, thereby driving the pressurizing block 6 to slide in the pressurizing groove 501 toward the ear pad 8, thereby increasing the squeezing force of the ear pad 8 on the patient's affected area; thereby, pressure adjustment is performed, postoperative complications are avoided, pain in the surgical area of ​​the patient is reduced, and comfort is improved.

[0061] In another embodiment of the present invention, a rotating sleeve 203 rotatably connected to the connecting plate 4 is fixedly installed on the adjusting block 2, a limiting block 3 is slidably engaged in the rotating sleeve 203, a limiting protrusion 204 is fixedly installed in the rotating sleeve 203, a limiting groove 301 slidably engaged with the limiting protrusion 204 is opened on the limiting block 3, a first locking tooth block 302 is fixedly installed on the limiting block 3; a second locking tooth block 401 cooperating with the first locking tooth block 302 is fixedly installed on the connecting plate 4.

[0062] Taking the embodiment combining all the features described in the present application as an example, when in use, before the ear pad 8 is brought into contact with the patient's ear, an external force is applied to the first locking tooth block 302 to move away from the rotating sleeve 203, thereby driving the limit block 3 to slide in the rotating sleeve 203, so that the first locking tooth block 302 is disengaged from the second locking tooth block 401. At this time, the connecting plate 4 can rotate on the adjusting block 2, thereby reducing the difficulty of wearing the ear pad 8 and increasing the fit between the ear pad 8 and the patient's ear.

[0063] After the pressurizing mechanism, the position adjusting mechanism and the fitting mechanism have completed their operation, an external force is applied to the first locking tooth block 302 to move in the direction close to the rotating sleeve 203, so that the limit block 3 slides in the rotating sleeve 203, so that the first locking tooth block 302 and the second locking tooth block 401 cooperate with each other, and the locking action of the second locking tooth block 401 on the first locking tooth block 302 can limit the rotation of the limit block 3, and the mutual interference action between the limit groove 301 and the limit protrusion 204 can limit the rotation of the connecting plate 4 on the rotating sleeve 203, so that the ear pad 8 can maintain a fitting angle with the patient's ear, so that the squeezing force and squeezing direction of the ear pad 8 on the patient's ear will not change easily.

[0064] In another embodiment of the present invention, a plurality of groups of protrusions are fixedly mounted on the first locking tooth block 302 , and the protrusions are in the shape of isosceles triangles with steep hypotenuses.

[0065] Taking the embodiment combining all the features recorded in the present application as an example, when in use, the first locking tooth block 302 and the second locking tooth block 401 can be kept in a relatively static state through the bite action of the protrusion on the first locking tooth block 302 and the protrusion on the second locking tooth block 401 (increasing the difficulty of driving the second locking tooth block 401 to rotate by rotating the connecting plate 4), so that the connecting plate 4 and the adjustment block 2 can maintain an unchanged angle, so that the squeezing force and squeezing direction of the ear pad 8 on the patient's ear will not change easily.

[0066] In another embodiment of the present invention, the head-mounted body 1 is elastic.

[0067] Taking the embodiment combining all the features described in the present application as an example, when in use, the head-mounted body 1 is elastic, and its elastic force is used to offset the force generated by a series of muscle movements around the ear caused by the patient's talking, chewing, and turning the head. This force acts on the ear pad 8 in a direction opposite to the squeezing force of the ear pad 8, thereby increasing the comfort of the patient wearing the device.

[0068] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
