DETAILED DESCRIPTION

[0035] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in further detail below with reference to the drawings and in combination with the embodiments.

[0036] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings accompanying the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should fall within the scope of protection of the present application. ​​​​

[0037] As Figures 1-2 shown, the present application provides a drainage device for rhinoplasty, comprising a negative pressure mechanism 1 for generating negative pressure to guide the liquid at the wound to flow out;

[0038] The negative pressure mechanism 1 comprises a syringe barrel 10, which is an important part for making negative pressure and is used to contain the drained liquid, and a piston 14 is slidably arranged inside the syringe barrel 10;

[0039] It should be noted that the piston 14 is tightly attached to the inner wall of the syringe barrel 10, which can effectively prevent external air from entering the syringe barrel 10, thereby maintaining the sealing state inside the syringe barrel 10. When the piston 14 is slowly and smoothly moved in the syringe barrel 10, the volume inside the syringe barrel 10 can be increased. Due to the sealing property of the piston 14, external air cannot quickly enter the inside of the syringe barrel 10 to fill the newly added volume, so the air pressure inside the syringe barrel 10 will gradually decrease as the volume increases, thereby forming negative pressure;

[0040] And a handle 13 is fixedly arranged on one side of the piston 14, which is used to facilitate medical staff to pull the piston 14 to slide inside the syringe barrel 10;

[0041] At the same time, a connecting head 11 is detachably arranged at the output end of the syringe barrel 10, which is used to connect the syringe barrel 10 with other components, and further maintains the sealing property of the syringe barrel 10, and a drainage tube 12 is detachably arranged at the other end of the connecting head 11, which is a key component for draining excess liquid or gas at the surgical site. One end of the drainage tube 12 is connected to the syringe barrel 10 through the connecting head 11, and the other end is inserted into the site that needs to be drained;

[0042] Before negative pressure drainage is needed, medical staff first need to connect one end of the drainage tube 12 to the syringe barrel 10 through the connecting head 11. After the connection is completed, the handle 13 can be slowly and smoothly pulled to make the piston 14 slide inside the syringe barrel 10, thereby forming negative pressure inside the syringe barrel 10, and the pulling of the handle 13 can be stopped until the required negative pressure level is reached;

[0043] When negative pressure is generated, the other end of the drainage tube 12 is quickly placed in the wound or liquid accumulation area that needs to be drained, thereby sucking the liquid into the syringe barrel 10 through the drainage tube 12. When the liquid in the syringe barrel 10 reaches a certain degree, a new syringe barrel 10 is replaced in time to continue the drainage;

[0044] As Figure 1 and Figures 3-4As shown, in order to prevent the occurrence of slippage during the drainage process due to patient activity or skin oil, sweating and other conditions, thereby interrupting the drainage process, affecting the drainage effect, causing wound effusion, swelling and other problems, therefore, a fixing mechanism 2 is installed on the syringe barrel 10, which is used to fix the negative pressure mechanism 1 on a certain part of the patient;

[0045] The fixing mechanism 2 includes a bracket 20, which is arc-shaped, and the two ends of the bracket 20 are used to be erected on the patient's ear position, and in order to fix the negative pressure mechanism 1 on the bracket 20, a support frame 22 is fixed on one side of the bracket 20, which is hollow inside, used for placing the drainage tube 12, and a locking assembly 24 is fixed on the outside of the support frame 22, which is used to lock the negative pressure mechanism 1 on the bracket 20, thereby preventing slippage in the case of patient activity or skin oil, sweating and other conditions;

[0046] The locking assembly 24 includes a fixed seat 241 fixed on the outside of the support frame 22, one side of the fixed seat 241 is fixedly provided with a fixed ring 243, the fixed ring 243 is hinged with a movable ring 244, and a locking block 242 is fixedly arranged at one end of the movable ring 244 and the fixed ring 243, the locking block 242 is provided with a locking hole (not shown in the figure), and a positioning pin 245 is detachably arranged in the locking hole, which is used to fix the negative pressure mechanism 1 by locking the fixed ring 243 and the movable ring 244;

[0047] When the drainage begins, the syringe barrel 10 can be placed on the fixed ring 243, and then the movable ring 244 is rotated until the locking block 242 of the fixed ring 243 and the movable ring 244 are in contact, and then the positioning pin 245 is clamped into the locking hole in the locking block 242, and the syringe barrel 10 is locked to prevent falling during use;

[0048] Finally, one end of the drainage tube 12 is inserted through the support frame 22 until it is placed on the area of the patient that needs to be drained, that is, the fixation of the negative pressure mechanism 1 is completed;

[0049] And in order to prevent the bracket 20 from falling off when the patient moves, a clamping block 21 is fixed at both ends of the bracket 20, which is used to clamp the bracket 20 on the patient's ear;

[0050] Meanwhile, in order to fix the support 20, prevent it from falling off when the patient is moving, a sliding assembly is fixed on one of the clamping blocks 21, which comprises a mounting seat 25 fixed on the clamping block 21, a sliding groove (not shown in the figure) is formed in the mounting seat 25, a sliding block 26 is slidably arranged in the sliding groove, and a blocking block (not shown in the figure) is fixed at both ends of the sliding groove, which is used to prevent the sliding block 26 from falling off;

[0051] Meanwhile, a clamping strip 27 is fixed on the sliding block 26, which is made of elastic material, and is arranged along the sliding groove and extends to the outside through the blocking block, so that the clamping strip 27 can drive the sliding block 26 to slide in the sliding groove by pulling it, a plurality of positioning holes 28 are formed in the clamping strip 27, which are used for positioning and fixing;

[0052] And the end of the clamping strip 27 on the other clamping block 21 is fixed with a positioning column 29 (refer to Figure 5 ), which corresponds to the positioning hole 28, so that the support 20 can be tightened by clamping the positioning column 29 into the positioning hole 28, thereby achieving the purpose of fixing the support 20, and the positioning column 29 can be clamped into different positioning holes 28 to adapt to different sizes of the head;

[0053] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
