Description

Technical Field

[0001] This utility model belongs to the technical field of oral treatment auxiliary equipment, specifically relating to a support device for a saliva suction tube for oral use. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] During oral disease treatment, it's essential to promptly remove the cooling water from high-speed handpieces, dental scalers, and other equipment, as well as the patient's saliva. This process is known as saliva suction. Proper saliva suction maintains a clear field of vision, facilitating precise manipulation and preventing saliva contamination of the treatment area. This allows for uninterrupted treatment, improving efficiency and effectiveness. Furthermore, it eliminates the need for patients to frequently sit up and rinse their mouths, saving time and increasing patient comfort.

[0004] Currently, routine medical procedures primarily utilize disposable saliva suction tubes. These tubes are held by an assistant or bent at an angle and placed near the corner of the patient's mouth to suction out the saliva and water mixture. The saliva then passes through a flexible tube connected to the suction tube (the suction pipette) and drains through a dedicated channel connected to the treatment chair. Saliva suction tubes are typically made of plastic tubing. Although lightweight, the tubing itself still has some weight. When the suction tube is in use, the water flowing through it adds to the weight, causing instability and making the tube prone to tilting in the mouth, affecting the doctor's manipulation. Furthermore, the downward pull of gravity on the corner of the patient's mouth can cause discomfort, negatively impacting the patient's experience. In clinical practice, four-handed saliva suction, where an assistant holds the suction tube, can solve these problems, but it increases manpower requirements. For clinics or hospitals unable to perform four-handed saliva suction, these issues significantly hinder the doctor's work and cause patient discomfort. Utility Model Content

[0005] To address the aforementioned issues, this invention provides a support device for oral saliva suction tubes, which can support the weight of the saliva suction tube, making it easier to fix the disposable saliva suction tube relatively in the patient's mouth without affecting the doctor's operation; at the same time, since there is no gravitational pull, it does not put pressure on the corners of the patient's mouth, thus improving the patient's comfort.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A support device for an oral suction tube includes a first suction tube clamp and a second suction tube clamp.

[0024] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0025] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a support device for an oral saliva suction tube, such as... Figure 1 As shown, it includes a first saliva suction tube clamp 1 and a second saliva suction tube clamp 4. One end of the first saliva suction tube clamp 1 is connected to a first connecting rod 2, and one end of the first connecting rod 2 is connected to a first U-shaped metal piece 3. One end of the second saliva suction tube clamp 4 is connected to a second connecting rod 5, and one end of the second connecting rod 5 is connected to a second U-shaped metal piece 6. The first U-shaped metal piece 3 and the second U-shaped metal piece 6 are cross-connected.

[0026] The saliva tube 11 can be held by the saliva tube clamp. The clamping direction of the saliva tube clamp is adjustable so that the clamping direction is always perpendicular to the ground after clamping the saliva tube 11. The clamping force of the saliva tube clamp is adjustable so that it is neither too tight nor too loose. This allows the saliva tube clamp to hold the saliva tube 11 and prevent it from moving downward due to gravity, and it is also convenient for the saliva tube 11 to be inserted horizontally into the saliva tube clamp.

[0027] The screw is connected to the connecting rod, but not tightened. This allows the saliva straw to hang naturally towards the ground due to gravity after the clamp holds it, while the clamp rotates at a certain angle due to the weight of the straw. Alternatively, the screw can be tightened to fix the clamp's gripping direction perpendicular to the ground. The saliva straw clamp is made of a flexible metal material; the tightness of the clamp can be adjusted by tightening and loosening the clamp opening.

[0028] The first U-shaped metal piece 3 and the second U-shaped metal piece 6 are fixed to the metal strip at the head and neck joint of the dental chair by the third flat-head screw 9. Then, the suction tube clamp and the connecting rod work together to support the weight of the suction tube 11, so that the disposable suction tube 10 can be relatively fixed in the patient's mouth without affecting the doctor's operation. At the same time, since the position of the suction tube 11 is fixed, there is no gravity pulling during use, which does not put pressure on the corners of the patient's mouth and improves the patient's comfort.

[0029] The first saliva suction tube clamp 1 has a threaded hole, and one end of the first connecting rod has a threaded hole. The first saliva suction tube clamp 1 and the first connecting rod are connected by a first flat-head screw 7. The other end of the first connecting rod has a threaded hole, and the first U-shaped metal plate 3 has a threaded hole. The first connecting rod and the first U-shaped metal plate 3 are connected by a second flat-head screw 8.

[0030] The second saliva suction tube clamp 4 has a threaded hole, and one end of the second connecting rod has a threaded hole. The second saliva suction tube clamp 4 and the second connecting rod are connected by a first flat-head screw 7. The other end of the second connecting rod has a threaded hole, and the second U-shaped metal plate 6 has a threaded hole. The second connecting rod and the second U-shaped metal plate 6 are connected by a second flat-head screw 8.

[0031] Both the first connecting rod 2 and the second connecting rod 5 are lightweight metal rods with threaded holes at both ends. One end is connected to the tail end of the saliva suction tube clamp via a first flat-head screw 7, and the other end is connected and fixed to the tail end of the U-shaped metal plate via a second flat-head screw 8. The connecting rods can also be connected to the U-shaped metal plate by welding.

[0032] The first saliva suction tube clamp 1 and the second saliva suction tube clamp 4 have the same structure. The first saliva suction tube clamp 1 and the second saliva suction tube clamp 4 are rigid metal clamps, both of which are flexible metal sheet-shaped bending structures used to clamp the saliva suction tube. During treatment, the disposable saliva suction tube 10 is first placed in a suitable position in the patient's oral cavity, and then the saliva suction tube 11 is naturally lowered to the horizontal position of the saliva suction tube clamp and inserted into the saliva suction tube clamp for fixation.

[0033] Threaded holes are provided at the upper and lower ends of the first U-shaped metal sheet 3 and the second U-shaped metal sheet 6. A third flat-head screw is provided at the mating position of the first U-shaped metal sheet 3 and the second U-shaped metal sheet 6. The third flat-head screw connects the first U-shaped metal sheet 3 and the second U-shaped metal sheet 6, and the third flat-head screws are symmetrically arranged.

[0034] The first U-shaped metal piece 3 and the second U-shaped metal piece 6 have threaded holes for inserting flat-head screws at the top, bottom and tail ends. The first U-shaped metal piece 3 and the second U-shaped metal piece 6 are connected and fixed to the connecting rod through the small hole at the tail end using the second flat-head screw 8. The first U-shaped metal piece 3 and the second U-shaped metal piece 6 are cross-connected and the threaded holes are aligned. The first U-shaped metal piece 3 and the second U-shaped metal piece 6 are fixed to the metal strip at the head and neck joint of the dental chair by the third flat-head screw 9.

[0035] like Figure 2 As shown, a saliva suction tube 11 is mounted on the first suction tube clamp 1. A disposable saliva suction tube 10 is attached to one end of the suction tube 11. The saliva suction tube 11 is an important structural component of the dental chair, transporting saliva and water from the oral cavity. One end is a plastic tube connected to the dental chair; the other end is a metal tube connected to the disposable saliva suction tube. The disposable saliva suction tube is a single-use consumable. During use, one end is inserted into the metal tube and connected by friction, while the other end is placed in the patient's mouth. After the procedure, the disposable saliva suction tube is disposed of.

[0036] The saliva suction tube clamp and connecting rod form the main structure, while the U-shaped metal plate serves as the fixing device, which is an auxiliary structure. The auxiliary structure can be modified according to the different ways the headrest of the dental chair is connected to the chair body. For example, if the headrest is connected to the chair body by two metal pillars, the U-shaped metal plate of the fixing device can be designed in a wave shape suitable for fixing. Alternatively, during the manufacturing of the dental chair, the main structure of this device can be directly integrated and fixed to the chair (removing the U-shaped metal plate and welding the connecting rod directly to the metal strip or metal pillar at the head-neck joint of the dental chair).

[0037] The method of using the support device is as follows: First, connect the first connecting rod 2 and the first suction tube clamp 1 with the first flat-head screw 7, and connect the second connecting rod 5 and the second suction tube clamp 4; then connect the first connecting rod 2 and the first U-shaped metal piece 3 with the second flat-head screw 8, and connect the second connecting rod 5 and the second U-shaped metal piece 6; next, align the first U-shaped metal piece 3 and the second U-shaped metal piece 6 with the metal strip at the head and neck joint of the dental chair, and connect the first U-shaped metal piece 3 and the second U-shaped metal piece 6 with the third flat-head screw 9; finally, clamp the suction tube 11 with the suction tube clamp to perform suction; by loosening the first flat-head screw 7, then rotating the suction tube clamp to the desired angle, and then tightening the first flat-head screw 7, the clamping direction of the suction tube clamp can be adjusted so that the clamping direction of the suction tube 11 is always perpendicular to the ground after clamping the suction tube 11, making it convenient for the suction tube 11 to be inserted horizontally into the suction tube clamp.

[0038] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
