[0022] Embodiments of the present application will be described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0023] Reference will be made to Figs. 1-2 A saliva suction device 100 according to an embodiment of the present application is described below.

[0024] As Figs. 1-2 shown, the saliva suction device 100 according to an embodiment of the present application comprises a saliva suction head 10 and a connecting pipe 20.

[0025] The saliva suction head 10 is the part of the saliva suction device 100 placed in the oral cavity, and the connecting pipe 20 is the part connecting the saliva suction head 10 and the operating device. Specifically, the saliva suction device 100 is connected to the operating device through the connecting pipe 20 to generate negative pressure inside the saliva suction device 100, thereby sucking saliva in the oral cavity.

[0026] Specifically, the saliva suction head 10 is provided with a bite portion 11, and the bite portion 11 is formed with an anti-skid structure 12. It can be understood that the bite portion 11 of the saliva suction head 10 is the position for the patient to bite, and thus the bite portion 11 is formed with the anti-skid structure 12, which can increase the friction between the teeth and the saliva suction head 10, thereby effectively preventing the saliva suction head 10 from falling out during use, so as to improve the reliability of the saliva suction device 100 during use and ensure the continuity of saliva suction.

[0027] The saliva suction head 10 is formed with a cavity inside, and the saliva suction head 10 is provided with a plurality of suction holes 13, which are in communication with the cavity; one end of the connecting pipe 20 is connected to the saliva suction head 10, and the connecting pipe 20 is formed with a flow passage inside, which is in communication with the cavity.

[0028] The flow passage and the cavity are in communication to form a complete flow channel to ensure that saliva can be discharged from the saliva suction head 10; the plurality of suction holes 13 are used to communicate the cavity and the external environment, so that saliva can enter the cavity of the saliva suction head 10 from the oral cavity and then be discharged through the connecting pipe 20. It should be noted that the discharge of saliva is mainly through negative pressure adsorption, and thus the other end of the connecting pipe 20 is in communication with the negative pressure system of the operating device.

[0029] Specifically, during use, the operator first connects the other end of the connecting pipe 20 to the stomatological negative pressure system. Then, the operator holds the connecting pipe 20 by hand, places the saliva suction head 10 on the occlusal surface of the teeth on one side of the patient's mouth, so that the patient can occlude the occlusion part 11, and then performs the operation on the patient's teeth. When saliva continuously secretes in the patient's mouth, the saliva is sucked into the cavity of the saliva suction head 10 through the suction hole 13 on the saliva suction head 10, and then is discharged through the communication channel of the connecting pipe 20. In this way, the influence of a large amount of saliva on the operation of the operator during the operation can be effectively avoided, and the operation reliability of the operator can be improved.

[0030] It should be noted that the saliva suction device 100 of the present application can be used in the process of attaching accessories. On the one hand, when the teeth are coated with adhesive, the saliva suction device 100 can suck saliva at any time, thereby avoiding the influence of saliva on the adhesion of the adhesive, and improving the stability of the attachment of the accessories. On the other hand, when the orthodontic template needs to be pressed and fixed after being worn, the saliva suction device 100 can play a role similar to that of “chewing gum”, thereby making the orthodontic template closely fit the teeth, playing a role of fixation. At the same time, the anti-skid structure 12 on the saliva suction head 10 can also avoid the problem of slipping during occlusion, thereby improving the accuracy and firmness of the attachment of the accessories. It should be further noted that the saliva suction device 100 of the present application can also be used in the operation process of other oral problems, and is not limited to the above operation.

[0031] Optionally, the connecting pipe 20 can also serve as a hand-held part of the operator. In this way, the operator can flexibly control the position of the saliva suction head 10 during the operation, thereby improving the operation efficiency and accuracy of the operator.

[0032] According to the saliva suction device 100 of the present application, the anti-skid structure 12 is arranged on the occlusion part 11, which can increase the friction between the occlusal surface of the teeth and the saliva suction head 10, thereby effectively preventing the saliva suction head 10 from falling out during use, improving the reliability of the saliva suction device 100 during use, and ensuring the continuity of saliva suction. At the same time, during the process of attaching accessories, the orthodontic template can be closely fitted to the teeth while ensuring moisture isolation, thereby improving the accuracy and firmness of the attachment of the accessories.

[0033] According to some embodiments of the present application, as Figs. 1-2As shown, the saliva suction head 10 is flat, and in the direction of the connecting pipe 20 towards the saliva suction head 10, the saliva suction head 10 extends along the radial direction of the connecting pipe 20 outwardly in an arc line. It can be understood that the shape of the saliva suction head 10 is similar to the letter "C", so that the shape of the saliva suction head 10 can be more fitted to the shape of the oral cavity, thereby facilitating the saliva suction head 10 to be better placed in the oral cavity. At the same time, the flat saliva suction head 10 can also enable the patient to better occlude, increase the comfort of occlusion, and reduce the foreign body sensation and discomfort in the patient's oral cavity; in addition, it can also reduce the occupied space of the saliva suction head 10, thereby improving the operation space in the oral cavity and reducing the operation difficulty of the doctor.

[0034] According to some embodiments of the present application, the occlusion part 11 is formed with a groove recessed from one side surface to the other side surface in the thickness direction of the saliva suction head 10. In this way, when the patient occludes, the teeth can cooperate with the groove, which can increase the firmness of the patient's occlusion, prevent the saliva suction device 100 from slipping out and slipping during use, and thereby improve the reliability of the operation.

[0035] According to some embodiments of the present application, as shown, Figs. 1-2 The anti-skid structure 12 includes a plurality of ribs arranged on the bottom wall of the groove. The structure of the rib is relatively simple, and therefore, using the rib structure as the anti-skid structure 12 can reduce the production difficulty of the saliva suction device 100, thereby reducing the production cost of the saliva suction device 100.

[0036] It should be noted that the rib can have various shapes, for example, the rib can be a long strip-shaped reinforcing rib, or a protruding scattered block.

[0037] For example, the number of ribs can be two, three or more.

[0038] According to some embodiments of the present application, in the direction of the connecting pipe 20 towards the saliva suction head 10, the groove extends outwardly in an arc line along the radial direction of the connecting pipe 20. It can be understood that the extension direction of the groove conforms to the direction of the teeth, and therefore, when the patient occludes, the teeth can be adapted to the groove, thereby improving the comfort and stability of the patient during occlusion, and thereby reducing the risk of the saliva suction device 100 slipping out and slipping during use.

[0039] According to some embodiments of the present application, in the direction of the connecting pipe 20 towards the saliva suction head 10, the width dimension of the groove gradually increases. It should be noted that the width of the teeth gradually increases in the direction from the middle to the sides, and therefore, in the direction of the connecting pipe 20 towards the saliva suction head 10, the width dimension of the groove gradually increases. It can be understood that the size of the groove can be matched with the size of the teeth, thereby further improving the comfort and stability of the patient during occlusion.

[0040] According to some embodiments of the present application, the number of grooves is two, and the two grooves are symmetrically arranged on the two side surfaces of the saliva suction head 10 in the thickness direction, and the bottom walls of the two grooves are in abutment. In this way, the thickness of the saliva suction head 10 can be further reduced, and the occupied space of the saliva suction head 10 can be reduced, so that the operation space in the oral cavity can be improved, and the operation difficulty of the doctor can be reduced; at the same time, the two grooves can also make the occlusion more stable, so that the risk of the saliva suction device 100 being pulled out and the risk of slipping can be further reduced when in use.

[0041] According to some embodiments of the present application, the cavity is formed in the shape of an annulus extending circumferentially around the occlusion part 11, and the plurality of suction holes 13 are connected to the flow channel through the cavity. In this way, the saliva can be sucked out in the circumferential direction of the occlusion part 11, so that the rate of saliva suction can be further improved; at the same time, the cavity is formed in the shape of an annulus extending circumferentially around the occlusion part 11, so that the cavity can be unaffected by the occlusion, thereby ensuring that the saliva can be sucked out.

[0042] According to some embodiments of the present application, as shown in Figs. 1-2 It should be noted that saliva generally accumulates on the inside of the oral cavity, and therefore, the plurality of suction holes 13 arranged at the end of the saliva suction head 10 away from the connecting pipe 20 can better discharge the saliva.

[0043] It should be further noted that the plurality of suction holes 13 can be arranged on the end face of the end of the saliva suction head 10 away from the connecting pipe 20, or can be arranged on the two side end faces of the end of the saliva suction head 10 away from the connecting pipe 20 in the thickness direction or the width direction, or can be arranged on each side face and end face in the circumferential direction, wherein the specific arrangement position is designed according to the actual situation.

[0044] According to some embodiments of the present application, the saliva suction device 100 is an integral molded part. In this way, the processing difficulty of the saliva suction device 100 can be reduced, so that the production rate of the saliva suction device 100 can be improved, the production cost of the saliva suction device 100 can be reduced, and at the same time, the number of connection points can be reduced, so that the structural strength of the saliva suction device 100 can be improved.

[0045] Optionally, the saliva suction device 100 is a transparent flexible part, so that the flexibility and visibility of the saliva suction device 100 as a whole can be ensured, so that the user experience can be improved.
