Description

Technical Field

[0001] This utility model relates to the field of dental instrument technology, and in particular to a saliva absorber for tooth extraction. Background Technology

[0002] Currently, in dental and oral treatments at major hospitals and clinics, cotton balls or rigid plastic tubes are commonly used to directly collect and drain saliva from the mouth. This is not only very uncomfortable for patients, but it can also easily cause abnormal sensations and lead to vomiting, requiring the doctor to interrupt the diagnosis or treatment process.

[0003] In current dental treatments, cotton balls are used to fill the patient's cheeks and teeth, which cannot fully expose the teeth and other areas that need treatment. The cotton balls also need to be changed frequently, causing interruptions to the doctor's treatment and increasing repetitive and meaningless workload. Alternatively, a drainage plastic tube connected to a ventilation pump is used to suction saliva with the tip of the tube. However, the drainage plastic tube only suctions saliva locally, covering a small area. At the same time, the drainage plastic tube can damage the oral lining due to excessive force, and the doctor also needs to frequently change the suction position. Summary of the Invention

[0004] This invention provides a saliva absorber for tooth extraction. The porous outer gauze layer and the soft outer medicated cotton layer ensure comfort upon contact with the patient's mouth and absorb saliva. The microporous support allows saliva to seep out as extremely fine particles from the medicated cotton through the connecting holes. The combination of the microporous support and the outer medicated cotton layer not only eliminates the noise of air suction but also avoids the noise of rapid water flow, creating a stable and quiet environment. The U-shaped clip holds the microporous support to both sides of the tooth, achieving fixed position operation and eliminating the need for manual handling.

[0005] This utility model provides a saliva absorber for tooth extraction, specifically including a microporous support, an outer cotton layer, and a U-shaped clip. The outer cotton layer is fixedly fixed around the outside of the microporous support, the U-shaped clip is provided above the microporous support, the lower part of the microporous support is provided with a ring array of connecting holes, the top of the microporous support is fixedly connected to an upper connecting slide, and the tail of the microporous support is connected and fixedly connected to a drainage tube frame.

[0006] Furthermore, the interior of the microporous scaffold is connected to the exterior through a connecting hole, and the outer cotton wool layer surrounds and covers the outside of the connecting hole. A negative pressure is generated inside the microporous scaffold, and the saliva in the outer cotton wool layer seeps out as extremely fine particles from the cotton wool into the microporous scaffold through the connecting hole.

[0007] Furthermore, the outer cotton layer is surrounded by an outer gauze layer with a mesh structure. The outer cotton layer and the outer gauze layer are in close contact with the inside of the oral cavity. The porosity of the outer gauze layer and the softness of the outer cotton layer enhance the comfort of contact with the patient's oral cavity.

[0008] Furthermore, the U-shaped clip is an inverted U-shaped elastic structure, and side connecting sliding columns are fixedly connected to both sides of the U-shaped clip.

[0009] Furthermore, the side connecting slides on both sides of the U-shaped clip are connected to the upper connecting slide, and the side connecting slide and the upper connecting slide are axially slidably connected. The sliding of the side connecting slide and the upper connecting slide adjusts the position between the U-shaped clip and the microporous support.

[0010] Furthermore, the upper connecting slide and microporous support on both sides of the U-shaped clip support move closer together, and the microporous support is clamped on both sides of the tooth to achieve the position fixation operation of the microporous support.

[0011] Furthermore, the microporous scaffold is a flexible structure, with an outer cotton layer surrounding and covering the outside of the upper connecting slide. The outer cotton layer and outer gauze layer of the microporous scaffold are in close contact with the inside of the oral cavity. The porous nature of the soft outer gauze layer and the contact between the outer cotton layer and the patient's oral cavity improve comfort, and the outer cotton layer absorbs saliva that seeps out of the oral cavity.

[0012] This utility model provides a saliva absorber for tooth extraction, which has the following beneficial effects:

[0013] The porous outer gauze layer and the soft outer medicated cotton layer ensure both comfort upon contact with the patient's mouth and perfect absorption of saliva, preventing it from dripping. The microporous support allows saliva to seep out as extremely fine particles from the medicated cotton into the microporous support through the connecting holes, and then flows out into the negative pressure machine through the drainage tube, eliminating the need for frequent cotton ball replacements.

[0014] The microporous scaffold indirectly contacts the oral cavity and saliva through the outer medicated cotton layer, avoiding the damage to the oral lining that occurs when existing drainage plastic tubes directly contact the oral cavity. The combination of the microporous scaffold and the outer medicated cotton layer not only eliminates the noise of air suction but also avoids the noise of rapid water flow, creating a stable and quiet environment. U-shaped clips hold the microporous scaffold on both sides of the teeth, achieving fixed positioning of the microporous scaffold and eliminating the need for manual handling, thus freeing up the doctor's hands during treatment.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] This invention proposes a saliva absorber for tooth extraction, comprising a microporous support 1, an outer cotton swab layer 2, and a U-shaped clip 3. The lower part of the microporous support 1 has a ring array of connecting holes 101. An upper connecting slide 102 is fixedly connected to the top of the microporous support 1. A drainage tube frame 103 is fixedly connected to the tail of the microporous support 1. The interior of the microporous support 1 communicates with the exterior through the connecting holes 101. The outer cotton swab layer 2 surrounds and covers the outside of the connecting holes 101. A negative pressure is generated inside the microporous support 1, allowing saliva in the outer cotton swab layer 201 to seep out as extremely fine particles into the microporous support 1 through the connecting holes 101. The outer cotton swab layer 2 is fixedly surrounded on the outside of the microporous support 1. A U-shaped clip 3 is positioned above the microporous support 1. The U-shaped clip 3 is an inverted U-shaped elastic structure. Both sides of the U-shaped clip 3 are fixedly connected to side connecting slides 301. Both sides of the side connecting slides 301 of the U-shaped clip 3 are connected to upper connecting slides 102. The side connecting slides 301 and upper connecting slides 102 are axially slidably connected. The sliding adjustment of the side connecting slides 301 and upper connecting slides 102 adjusts the position between the U-shaped clip 3 and the microporous support 1, avoiding the U-shaped clip 3, which is higher than the tooth, from obstructing the view during tooth extraction. The U-shaped clip 3 supports the upper connecting slides 102 on both sides and the microporous support 1 to move closer together. The microporous support 1 is clamped on both sides of the tooth, realizing the fixed position operation of the microporous support 1, eliminating the need for personnel to hold the microporous support 1 and eliminating the need to constantly watch and operate the microporous support 1.

[0031] In this embodiment, the outer cotton swab layer 2 is surrounded by an outer gauze cotton layer 201, which has a mesh structure. The outer cotton swab layer 2 and the outer gauze cotton layer 201 are in close contact with the inside of the oral cavity. The porosity of the outer gauze cotton layer 201 and the softness of the outer cotton swab layer 2 improve the comfort of contact with the patient's oral cavity. The microporous support 1 indirectly contacts the oral cavity and saliva through the cooperation of the cotton swab material outer cotton swab layer 2, which optimizes the shortcomings of the existing drainage plastic tube that damages the oral lining when it directly contacts the oral cavity. It also eliminates the need for frequent cotton swab replacement, which would cause the doctor to interrupt treatment and increase the amount of repetitive and meaningless work.

[0032] In this embodiment, the microporous scaffold 1 is a flexible structure. The outer cotton layer 2 surrounds and covers the outside of the upper connecting slide 102. The outer cotton layer 2 and the outer gauze layer 201 of the microporous scaffold 1 are in close contact with the inside of the oral cavity. The porous nature of the soft outer gauze layer 201 and the contact between the outer cotton layer 2 and the patient's oral cavity improve comfort. The outer cotton layer 2 also perfectly absorbs saliva from the oral cavity, preventing saliva from flowing freely. The cotton-like material of the outer cotton layer 2 weakens the direct suction of the connecting hole 101 of the microporous scaffold 1 to the outside, eliminating the air suction noise of the microporous scaffold 1. The microporous scaffold 1 does not come into direct contact with saliva, avoiding the rapid water flow noise generated by the suction of the microporous scaffold 1 similar to that of a flow-guiding plastic tube.

[0033] In this second embodiment, based on the first embodiment, the U-shaped clip 3 is not used. A microporous support 1 and an outer cotton layer 2 are placed between the cheek and the tooth, enabling the microporous support 1 and the outer cotton layer 2 to be used in a single state, meeting different usage environments and habits. Alternatively, the U-shaped clip 3 may have a microporous support 1 on only one side, with the other side of the U-shaped clip 3 attached to the tooth through the outer cotton layer 2. The number of microporous supports 1 is reduced from two to one, reducing production costs.

[0034] The working principle of this embodiment is as follows: The U-shaped clip 3 holds the microporous support 1 on both sides of the teeth. The outer cotton swab layer 2 and the outer gauze layer 201 of the microporous support 1 are in close contact with the inside of the oral cavity. The porosity of the outer gauze layer 201 and the softness of the outer cotton swab layer 2 ensure both comfort when in contact with the patient's oral cavity and perfect absorption of saliva that seeps out of the oral cavity, preventing saliva from flowing arbitrarily. The drainage tube frame 103 is connected to the negative pressure pump, generating negative pressure inside the microporous support 1. The microporous support 1 allows saliva in the outer gauze layer 201 to seep out from the cotton swab as extremely fine particles into the microporous support 1 through the connecting hole 101. The saliva in the microporous support 1 flows out of the negative pressure pump through the drainage tube frame 103, realizing the collection of saliva and avoiding the situation where the cotton ball reaches the upper limit of saliva absorption. At the same time, the cotton ball expands the range of saliva absorption, possessing the dual advantages of the drainage plastic tube and the cotton ball, eliminating the need for frequent replacement of the cotton ball, which would cause interruption of the doctor's treatment and increase repetitive and meaningless workload.

[0035] The microporous stent 1 indirectly contacts the oral cavity and saliva through the outer cotton pad 2, avoiding the damage to the oral lining that occurs when the existing drainage plastic tube directly contacts the oral cavity. The outer cotton pad 2 weakens the direct suction of the microporous stent 1's connecting hole 101 to the outside, eliminating the noise of air suction. The microporous stent 1 does not directly contact saliva, avoiding the noise of rapid water flow generated by the suction of the microporous stent 1, thus creating a stable and quiet environment. The malleable microporous stent 1 and drainage tube frame 103 can be bent and fixed at will. The U-shaped clip 3 holds the microporous support 1 on both sides of the tooth, thus fixing the position of the microporous support 1. This eliminates the need for the operator to hold the microporous support 1, freeing up the operator's hands and preventing interruptions in treatment due to the operator holding the microporous support 1. The U-shaped clip 3 adjusts the position between the U-shaped clip 3 and the microporous support 1 through the side connecting slide 301 and the upper connecting slide 102, preventing the U-shaped clip 3 from obstructing the view during tooth extraction.
