Description

Technical Field

[0001] This utility model relates to the field of oral treatment instruments, specifically to a saliva suction tube with an anti-cheek suction tip. Background Technology

[0002] Saliva suction tubes are commonly used auxiliary tools in dental treatment. Their main function is to keep the oral operating area dry and clean by continuously suctioning, providing doctors with a clear view. Existing saliva suction tubes typically use a single-aperture suction head design and rely on a negative pressure system to generate suction to remove saliva, rinsing fluid, and other liquids.

[0003] In actual use, due to the unreasonable matching between the aperture size of the saliva suction head and the suction parameters, and the lack of an anti-adsorption buffer structure, the buccal mucosa is easily adsorbed to the saliva suction head port due to excessive negative pressure during suction. This not only causes pain and discomfort to the patient, but may also cause mucosal congestion, edema, or even mechanical damage due to prolonged adsorption.

[0004] Currently, although there are improved saliva suction tips with anti-cheek suction function on the market (i.e., anti-cheek suction tips), they generally use interference fit or complex snap-fit ​​structure to connect with the main body of the saliva suction tube, which requires medical staff to spend a lot of time on installation, alignment and disassembly cleaning during clinical operation, significantly increasing the complexity of operation and the workload of medical staff.

[0005] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0006] The purpose of this invention is to provide a saliva suction tube that prevents cheek suction.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A saliva suction tube with an anti-cheek-sucking tip, comprising a saliva suction tube body and an anti-cheek-sucking tip;

[0009] The main body of the saliva suction tube has a saliva suction end, and the saliva suction end is provided with a first snap-fit ​​component;

[0010] The anti-sucking cheek tip includes:

[0011] A sleeve end, used for sealing and fitting with the saliva suction end;

[0012] The second snap-fit ​​component is disposed at the socket end and is used for snap-fit ​​assembly with the first snap-fit ​​component.

[0013] An exhaust end is provided at the socket end and has an exhaust groove, at least a portion of which is located on the end face of the exhaust end away from the socket end.

[0014] The saliva straw is in an assembled state:

[0015] In the assembled state, the sleeve end is sleeved and assembled with the saliva suction end, and the first snap-fit ​​component is snap-fitted and assembled with the second snap-fit ​​component.

[0016] In the above solution, the anti-suction cheek tip works in conjunction with the main body of the suction tube to complete the suction operation. Due to the setting of the air vent, the negative pressure of the suction end can be prevented from adhering to the buccal mucosa, improving the patient experience and avoiding damage to the buccal mucosa.

[0017] The suction end and the socket end are connected and assembled to complete the initial assembly. The assembly stability of the suction end and the socket end is further improved by the snap-fit ​​assembly of the first snap-fit ​​component and the second snap-fit ​​component. The double fixation ensures the stable use of the suction tube while reducing the difficulty of installing and removing the anti-suction cheek tip. This reduces the complexity of operation and alleviates the workload of medical staff.

[0018] In a further technical solution, a portion of the outer wall of the suction end is recessed to form a groove, and the groove constitutes the first snap-fit ​​component;

[0019] The sleeve end itself forms a receiving groove for accommodating the saliva suction end, and the second snap-fit ​​member is disposed on the inner wall of the receiving groove;

[0020] The socket end and at least one of the second snap-fit ​​components are elastic;

[0021] In the assembled state, the second snap-fit ​​component snaps into the slot.

[0022] This embodiment further clarifies the implementation method of the above-mentioned snap-fit ​​assembly, that is, the snap-fit ​​assembly is performed by the second snap-fit ​​component and the slot, which is simple and convenient.

[0023] At least one of the socket end and the second snap-fit ​​component is elastic, facilitating the smooth insertion of the second snap-fit ​​component into the slot while the socket end and the saliva suction end are in contact. The socket end may have a groove to accommodate the end of the second snap-fit ​​component.

[0024] The card slot constitutes the first card connector, which can avoid adding a structure and reduce structural costs.

[0025] In a further technical solution, the slot is an annular groove;

[0026] The inner wall of the receiving groove is provided with a plurality of engaging protrusions, and each engaging protrusion is evenly distributed in a circle around the axis of the receiving groove, and each engaging protrusion constitutes the second engaging member;

[0027] In the assembled state, each of the engagement protrusions is located in the slot, realizing snap-fit ​​assembly.

[0028] The combination of annular grooves and multiple engaging protrusions further enhances the assembly stability of the saliva-suction end and the socket end, and also further improves the utilization of these structures on the saliva-suction end.

[0029] In a further technical solution, the socket end includes a plurality of elastic fastening tabs, and each of the fastening tabs surrounds and forms the receiving groove;

[0030] Each of the fastening pieces is evenly distributed circumferentially around the axis of the receiving groove;

[0031] In the assembled state, each of the fastening tabs is tightly attached to the outer wall of the saliva suction end.

[0032] The fastening tab is elastic. On the one hand, the deformation of the fastening tab can allow the second snap-fit ​​to avoid the outer wall of the saliva suction end, and the reset of the fastening tab can allow the second snap-fit ​​to be inserted into the slot. On the other hand, the fastening tab can fit tightly against the outer wall of the saliva suction end, improving the assembly stability of the saliva suction end and the socket end.

[0033] When multiple fastening pieces are arranged separately, the structural cost can be reduced compared to using a ring, and the sleeve end can be easily bent to deform it.

[0034] When the fastening clip is tightly attached to the outer wall of the saliva suction end, it can prevent the saliva suction effect from being affected by a large gap between the outer wall of the saliva suction end and the inner wall of the sleeve end.

[0035] In a further technical solution, the exhaust grooves are provided in multiple ways, and each exhaust groove is evenly distributed in a circular pattern around the axis of the exhaust end.

[0036] The multiple venting channels ensure effective venting, thereby preventing the suction end from adhering to the buccal mucosa due to negative pressure, making it more suitable for situations with strong suction during saliva suction.

[0037] Each venting groove is evenly distributed in a circular pattern around the axis of the venting end, which improves the aesthetics and ensures uniform venting, further guaranteeing the effect of preventing the negative pressure of the suction end from adhering to the buccal mucosa.

[0038] In a further technical solution, the main body of the saliva suction tube includes a saliva delivery section connected to the suction end;

[0039] Along the length of the saliva suction tube body, the projection of the suction end and the projection of the anti-suction cheek tip are both covered by the projection of the saliva delivery section.

[0040] This implementation essentially restricts the shape (or size) of the suction end and the anti-suction cheek tip. For ease of understanding, let's take the saliva delivery section as a cylindrical tube structure as an example: In this case, compared to the suction end and the anti-suction cheek tip, the saliva delivery section protrudes radially (for example, all three could have the same radial dimension). By avoiding the protrusion of the anti-suction cheek tip, the degree of obstruction encountered when the suction tube moves in the oral cavity is reduced, improving the intraoral flexibility of the suction tube and thus enhancing the patient experience.

[0041] By avoiding the protrusion of the anti-sucking cheek tip, the placement of the saliva suction tube body can be prevented, thus ensuring the suction effect.

[0047] The working principle and advantages of this utility model are as follows:

[0048] The anti-suction buccal tip works in conjunction with the main body of the suction tube to complete the suction operation. Due to the design of the air vent, the negative pressure of the suction end can be prevented from adhering to the buccal mucosa, improving the patient experience and avoiding damage to the buccal mucosa.

[0049] The suction end and the socket end are connected and assembled to complete the initial assembly. The assembly stability of the suction end and the socket end is further improved by the snap-fit ​​assembly of the first snap-fit ​​component and the second snap-fit ​​component. The double fixation ensures the stable use of the suction tube while reducing the difficulty of installing and removing the anti-suction cheek tip. This reduces the complexity of operation and alleviates the workload of medical staff. Attached Figure Description

[0055] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0056] The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the embodiments of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0057] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0058] Example 1: See Figures 1-4 A saliva suction tube with an anti-cheek suction tip, comprising a saliva suction tube body 1 and an anti-cheek suction tip 2;

[0059] The saliva suction tube body 1 has a saliva suction end 11, and the saliva suction end 11 is provided with a first snap-fit ​​member 3;

[0060] The anti-sucking cheek tip 2 includes:

[0061] The sleeve end 21 is used for sealing and fitting with the saliva suction end 11;

[0062] The second snap-fit ​​component 22 is disposed on the sleeve end 21 and is used to snap-fit ​​and assemble with the first snap-fit ​​component 3.

[0063] An exhaust end 23 is provided at the socket end 21 and has an exhaust groove 231, at least a portion of which is located on the end face of the exhaust end 23 away from the socket end 21.

[0064] The saliva straw is in an assembled state:

[0065] In the assembled state, the sleeve end 21 is sleeved and assembled with the saliva suction end 11, and the first snap-fit ​​member 3 is snap-fitted and assembled with the second snap-fit ​​member 22.

[0066] The anti-suction cheek tip 2 works in conjunction with the main body of the saliva suction tube 1 to complete the saliva suction operation. Due to the setting of the air vent 231, the negative pressure of the suction end 11 can be prevented from adhering to the buccal mucosa, improving the patient experience and avoiding damage to the buccal mucosa.

[0067] The suction end 11 and the socket end 21 are connected and assembled to complete the initial assembly. The assembly stability of the suction end 11 and the socket end 21 is further improved by the snap-fit ​​assembly of the first snap-fit ​​part 3 and the second snap-fit ​​part 22. The double fixation makes the suction tube stable to use, while reducing the difficulty of installing and removing the anti-suction cheek tip 2. The complexity of operation is reduced to reduce the workload of medical staff.

[0068] It should be noted that this application does not change the working principle of the saliva suction tube; the specific saliva suction process can be referred to the existing technology. This application also does not change the working principle of the anti-sucking cheek tip 2.

[0069] A specific shape of the exhaust channel 231 is shown in the attached drawing.

[0070] See Figure 3 In this embodiment 1, a portion of the outer wall of the saliva suction end 11 is recessed to form a groove 4, and the groove 4 constitutes the first snap-fit ​​member 3;

[0071] The sleeve end 21 itself forms a receiving groove 5 for accommodating the saliva suction end 11, and the second snap-fit ​​member 22 is provided on the inner wall of the receiving groove 5.

[0072] At least one of the socket end 21 and the second snap-fit ​​member 22 is elastic;

[0073] In the assembled state, the second snap-fit ​​component 22 is snap-fitted into the slot 4.

[0074] This embodiment further clarifies the implementation method of the above-mentioned snap-fit ​​assembly, that is, the snap-fit ​​assembly is performed by the second snap-fit ​​component 22 and the slot 4, which is simple and convenient.

[0075] At least one of the socket end 21 and the second snap-fit ​​member 22 is elastic, which facilitates the smooth insertion of the second snap-fit ​​member 22 into the slot 4 based on the fit between the socket end 21 and the saliva suction end 11. The socket end 21 may be provided with a groove to accommodate the end of the second snap-fit ​​member 22.

[0076] The card slot 4 constitutes the first card connector 3, which can avoid adding a structure and reduce structural costs.

[0077] It should be noted that the flexible setting in this application can be achieved through materials, such as the second snap-fit ​​22, which is flexible due to the use of materials such as rubber.

[0078] See Figure 2 , Figure 3 In this embodiment 1, the slot 4 is an annular slot;

[0079] The inner wall of the receiving groove 5 is provided with a plurality of engaging protrusions 221, and each engaging protrusion 221 is evenly distributed in a circle around the axis of the receiving groove 5, and each engaging protrusion 221 constitutes the second engaging member 22.

[0080] In the assembled state, each of the engagement protrusions 221 engages with the slot 4.

[0081] The arrangement of the annular groove and multiple engaging protrusions 221 further improves the assembly stability of the saliva-suction end 11 and the sleeve end 21, and also further improves the utilization of these structures of the saliva-suction end 11.

[0082] See Figure 1 , Figure 3 In this embodiment 1, the socket end 21 includes a plurality of elastic fastening pieces 211, and each of the fastening pieces 211 surrounds to form the receiving groove 5;

[0083] Each of the fastening pieces 211 is evenly distributed circumferentially around the axis of the receiving groove 5;

[0084] In the assembled state, each of the fastening pieces 211 is tightly attached to the outer wall of the saliva suction end 11.

[0085] The saliva-suction end 11 and the socket end 21 can be fitted together or tightly attached; in this embodiment, they are tightly attached.

[0086] In the above scheme, at least one fastening piece 211 is connected to the second snap-fit ​​piece 22.

[0087] The fastening piece 211 is elastic. On the one hand, the deformation of the fastening piece 211 can cause the second snap-fit ​​piece 22 to avoid the outer wall of the saliva suction end 11, and the reset of the fastening piece 211 can cause the second snap-fit ​​piece 22 to be inserted into the slot 4. On the other hand, the fastening piece 211 can be tightly attached to the outer wall of the saliva suction end 11, improving the assembly stability of the saliva suction end 11 and the sleeve end 21.

[0088] When multiple fastening pieces 211 are arranged separately from each other, the structural cost can be reduced compared to using an annular ring, and it is also easier to bend the sleeve end 21 to deform it.

[0089] When the fastening piece 211 is tightly attached to the outer wall of the saliva-suction end 11, it can prevent the saliva-suction effect from being affected by a large gap between the outer wall of the saliva-suction end 11 and the inner wall of the sleeve end 21.

[0090] See Figure 3 In this embodiment 1, there are multiple exhaust grooves 231, and each exhaust groove 231 is evenly distributed in a circle around the axis of the exhaust end 23.

[0091] The multiple venting grooves 231 ensure venting effect, thereby preventing the suction end 11 from adhering to the buccal mucosa under negative pressure, making it more suitable for situations with greater suction force during saliva suction.

[0092] Each venting groove 231 is evenly distributed in a circular pattern around the axis of the venting end 23, which can improve the aesthetics and achieve uniform venting, further ensuring the effect of preventing the negative pressure of the suction end 11 from adhering to the buccal mucosa.

[0093] See Figure 2 In this embodiment 1, the saliva suction tube body 1 includes a saliva delivery section 12 connected to the saliva suction end 11.

[0094] Example 2: In the length direction of the saliva suction tube body 1, the projection of the saliva suction end 11 and the projection of the anti-suction cheek tip 2 are both covered by the projection of the saliva delivery section 12 (not shown).

[0095] When the first connector 3 is not part of the saliva suction end 11, its projection is also covered by the projection of the saliva delivery section 12.

[0096] This embodiment 2 essentially restricts the shape (or size) of the suction end 11 and the anti-suction cheek tip 2. For ease of understanding, the saliva delivery section 12 is illustrated as a circular tube structure: In this case, in the radial direction of the saliva delivery section 12, compared to the suction end 11 and the anti-suction cheek tip 2, the saliva delivery section 12 is convex (for example, the radial dimensions of the three can also be the same). By avoiding the protrusion of the anti-suction cheek tip 2, the degree of obstruction encountered when the saliva suction tube moves in the oral cavity is reduced, the intraoral movement flexibility of the saliva suction tube is improved, and thus the patient experience is enhanced.

[0097] By avoiding the protrusion of the anti-sucking cheek tip 2, it is also possible to prevent the anti-sucking cheek tip 2 from affecting the placement of the saliva suction tube body 1, thus ensuring the saliva suction effect.

[0098] In some embodiments, only the projection of the saliva-suction end 11 is covered by the projection of the saliva-transfer section 12. In this case, the saliva-suction end 11 is narrowed relative to the saliva-transfer section 12, while the projection of the anti-suction cheek tip 2 may be slightly larger than the projection of the saliva-transfer section 12.

[0099] The other structures of this embodiment 2 are the same as those of embodiment 1, and will not be described again here.

[0100] The specific settings (such as position settings) of each structure in this application can be referred to the accompanying drawings, but are not limited to the settings shown in the accompanying drawings.

[0101] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
