Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a saliva suction tube combination support. Background Technology

[0002] A saliva suction tube is a tool used in medical or oral care settings to suction saliva, blood, or other liquids. It is usually made of soft and durable plastic or rubber and is designed with a slender tube and a suction tip. It can be used with dental treatment equipment to effectively keep the treatment area clean and dry, improving treatment efficiency and patient comfort.

[0003] In existing technologies, dentists typically need to hold the suction tip of a saliva suction tube with one hand and control other instruments with the other. When additional auxiliary instruments are needed, the suction tube must be removed from the patient's mouth to retrieve the other instruments, which is quite cumbersome. In addition, the end of the saliva suction tube furthest from the suction tip is usually connected to a collection device. When the saliva suction tube is not needed, the operator needs to manually close the collection device, which may require the dentist to turn around during the operation, and the hands are easily contaminated due to contact. Therefore, a saliva suction tube combination support is proposed to solve the above problems. Utility Model Content

An adjustment knob 215 is fixedly connected to one end of the telescopic block 212 outside the handle 201. Figures 1-3 As shown, the handle 201 can be made of stainless steel, and the horizontal groove 204 can support the telescopic block 212 through the horizontal protrusion 214, thereby limiting the lifting and lowering movement of the adjustment knob 215.

[0017] A semi-cylinder 205 is fixedly installed on the inner wall of the handle 201 near the outer lifting groove 203. An inner lifting groove 206 is formed in the middle of the side of the semi-cylinder 205. The inner lifting groove 206 is aligned with the outer lifting groove 203 and extends vertically. Figure 3As shown, a gap is left between the semi-cylinder 205 and the inner left side of the handle 201, so that the saliva tube 107 can pass through and be clamped.

[0018] Guide grooves 207 are provided on both sides of the middle of the inner lifting groove 206. A guide shaft 208 is slidably connected to the inner side of each guide groove 207. A rotating rod 209 is embedded and fixed in the middle of the guide shaft 208. A pressing block 210 is fixedly installed on the upper side of the rotating rod 209. A sleeve 211 is rotatably connected to the lower outer wall of the rotating rod 209. Figures 4-5 As shown, the guide groove 207 has an angle of approximately 45 degrees with the vertical direction.

[0019] The inner wall of sleeve 211 is slidably connected to the end of telescopic block 212, and the inner side of sleeve 211 is slidably connected to horizontal protrusion 214. A return spring 213 is fixedly connected to the end of the inner wall of sleeve 211, and the other end of the return spring 213 is fixedly connected to the end face of telescopic block 212. Figures 4-5 As shown, the telescopic block 212 is restricted from sliding in the sleeve 211, and the telescopic block 212 cannot be completely disengaged from the inside of the sleeve 211. The return spring 213 pushes the telescopic block 212 toward the sleeve 211 to complete the push. The elastic coefficient of the return spring 213 is about 15 N / mm.

[0020] The combined bracket 1 includes a mounting base 101. One end of the top surface of the mounting base 101 is rotatably connected to a first rotating joint 102. The other end of the first rotating joint 102 is rotatably connected to a second rotating joint 103. The other end of the second rotating joint 103 is rotatably connected to a third rotating joint 104. The end of the third rotating joint 104 is rotatably connected to a grip handle 201. Mounting ears 105 are fixedly connected to the outer side walls of both the first and second rotating joints 102 and 103. A strap 1 is wrapped around the inner side of each mounting ear 105. 06. Each strap 106 has a saliva suction tube 107 penetrating and supporting its inner side. The end of the saliva suction tube 107 penetrates and clamps the handle 201, and the opening at the end of the saliva suction tube 107 is connected to the suction port 202. The outer wall of the saliva suction tube 107 abuts against the squeezing block 210.

Figure 1 As shown, each rotating joint of the combined bracket 1 uses a high-damping material (such as rubber or anti-slip coating) at the joint to provide continuous resistance through the viscoelasticity of the material itself, thus maintaining angular stability.

[0021] The working principle of this utility model: During dental treatment, the patient lies on the treatment chair, and the combined bracket 1 is fixed to the side of the treatment chair by fasteners or adhesives via the mounting base 101. The dentist can then push the handle 201 to bring the suction port 202 closer to the inside of the patient's mouth, making it convenient for the suction tube 107 to clean the inside of the patient's mouth. When performing a medical procedure on a patient's oral cavity and when the saliva suction tube 107 is not required, the dentist can press the adjustment knob 215, causing the horizontal protrusion 214 to disengage from the horizontal groove 204. The telescopic block 212 then pushes the return spring 213 to retract. The dentist can then push the adjustment knob 215 upwards until the telescopic block 212 slides to the top of the outer lifting groove 203. During this process, the guide shaft 208 slides upwards along the guide groove 207, the rotating rod 209 moves towards the saliva suction tube 107, and the squeezing block 210 gradually presses against the surface of the saliva suction tube 107. Until the saliva suction tube 107 is completely closed under the clamping of the squeezing block 210 and the inner wall of the grip 201, the adjusting knob 215 is gradually released. The return spring 213 releases its elastic potential energy and pushes the telescopic block 212 to move back to its original position. The horizontal protrusion 214 is inserted into the upper horizontal groove 204, thereby fixing the position of the guide shaft 208 inside the guide groove 207. The squeezing block 210 maintains the clamping state of the saliva suction tube 107. When the saliva suction tube 107 needs to be used again, the above operation is performed. The adjusting knob 215 is pressed down and moved down.

[0022] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
