Detailed description of the invention
To the technical scheme in this utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of this utility model protection.
Refer to Fig. 1 and Fig. 2, this utility model embodiment comprises:
A kind of dental care dental floss stick, comprising: dental floss holder 1 and expanded PTFE dental floss 2, and described dental floss holder 1 comprises one handle, and described handle one end is dental floss end, and described dental floss holder 1 other end is the pointed end of picking one's teeth, and can pick out the food being embedded in teeth space.
On described dental floss end, be fixed with the expanded PTFE dental floss 2 of two settings parallel to each other, two rooted tooth line tensioners are in the two sides of tooth, strengthen the frictional force of dental floss and tooth, by handle by a small margin move forward and backward up and down handle, more effectively remove the dental plaque of tooth side, tartar and food debris.
The body of expanded PTFE dental floss 2 is eptfe film, and described eptfe film surface is the micro-flank of tooth of burnishing.
Expanded PTFE is a kind of novel medical macromolecular materials, due to its good biocompatibility and distinctive microcellular structure, nontoxic, without carcinogenic, without side effect such as sensitization, and human tissue cell and blood vessel its micropore of can growing into, formative tissue connects, as autologous tissue, widely apply aspect health care.
This macromolecule new material has the microcellular structure of the perforation of interconnecting, and (micropore diameter at 8~30 μ m), the microfibre of these micropores and expanded PTFE and microfibre node have formed a kind of three-dimensional microporous membrane, the microfibre of expanded PTFE and microfibre node have formed the micro-flank of tooth of elastic-friction polishing of ups and downs softness, the micro-flank of tooth of elastic-friction polishing of this softness is used in people's dental surface health care polishing, as expanded PTFE dental floss 2, the neither adamantine layer of damage tooth, do not damage again gingiva, and can effectively remove the dental plaque of tooth side, tartar and food debris.
The core technology of the manufacture of expanded PTFE health dental floss teeth thin film: by polytetrafluoroethyldispersion dispersion resin and liquid extrusion aid be mixed in proportion-give be pressed into cylinder blank-by rolling process cylinder blank is laminated-through drying tunnel heat up slough the pore structure-sizing of extrusion aid-stretching microfibre (thickness <150 μ m)-rolling-inspection-ultraviolet radiation sterilizes-packs.
The thickness of described expanded PTFE dental floss 2 is less than 150 μ m.The width of described expanded PTFE dental floss 2 is less than or equal to 2.2mm.Select dental floss and the two rooted tooth line facewidth spacing of different-thickness to enter in different teeth spaces, effectively remove proximal surface and flank dental plaque, tartar and food debris, efficient safer more healthy.
The processing technology of described expanded PTFE dental floss 2 comprises the following steps:
1) get eptfe film and do technological preparation;
2) molding of eptfe film hobboing cutter is cut, the width of cutting is less than or equal to 2.2mm;
3), after having cut, carry out dry heat sterilization, then fixed length rolling;
4) carried out again ultraviolet radiation sterilization;
5) complete the making of expanded PTFE dental floss 2 after having sterilized.
The processing technology of described dental floss holder 1 comprises the following steps:
1) mould of dental floss holder 1 is fixed, dental floss 2 is fixed in mould simultaneously;
2) in mould, carry out injection moulding, dental floss 2 is connected and fixed firmly by injection moulding with dental floss holder 1;
3) parting, takes out dental floss holder 1;
4) dental floss holder 1 is tested, and carry out dry heat sterilization, make dental floss holder 1.
Dental floss stick of the present utility model can enter teeth space easily, can not cause extruding force, not damage tooth surface enamel; The soft micro-flank of tooth of elastic-friction polishing is used in efficient convenience in people's dental surface health care polishing.The soft micro-flank of tooth of elasticity micropore burnishing acts on the principle in people's dental surface health care polishing, effectively removes residue and bacterial plaque between teeth space, effectively prevents periodontal disease.
Dental floss stick of the present utility model in the two sides of tooth, has strengthened the frictional force of dental floss and tooth by double joint dental floss tensioner, by handle by a small margin move forward and backward up and down handle, more effectively remove the dental plaque of tooth side, tartar and food debris; The food being embedded in teeth space can be picked out in handle tip;
Dental floss stick of the present utility model can be massaged stimulates periodontal gingiva, increases the blood circulation of gingiva, thereby reaches the effect of dental care.Due to its good biocompatibility and distinctive microcellular structure, nontoxic, without carcinogenic, without side effect such as sensitization.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes this utility model description to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
