Description
Technical field
The utility model relates to a kind of special painless gingival sulcus drug delivery heads, are applied to local anaesthetics, antibiosis in tooth gingival sulcus
The administration of the drugs such as element.
Background technique
At present for the conveying of drug in tooth gingival sulcus, regular injection syringe needle and continuous rod, injection needle are clinically generallyd use
Head disadvantage are as follows: 1. pain, for such syringe needle since material is iron or stainless steel, needle point is more sharp, and patient usually feels in administration
Feel needle pricked pain.2. measuring bad control, regular injection syringe needle drug is conveyed through pinprick shaped opening, and pinprick shaped opening is narrow,
The bad control of dose, easy excess cause to waste.3. it is time-consuming, it is limited due to squeezing out drug in the pinprick shaped opening unit time, it infuses
It is very time-consuming to penetrate process.
Continuous rod disadvantage are as follows: 1. inaccurate, continuous club head volume is bigger than normal, cannot accurately be coated onto gingival sulcus drug, cause medicine
Beyond the region of objective existence overflows, and drug waste is serious and ineffective.2. it is time-consuming, it is time-consuming and laborious in order to reach effect.
Gum is the mucous membrane of mouth for being enclosed in neck portion, and gingival sulcus is cyclic annular narrow gap between gum and facing, average
Depth is 0.5-3mm, arc-shaped.The drug conveying of department of stomatology tooth gingival sulcus is different from other positions, does not need by sharp
Syringe needle penetrates soft tissue, but only that delivery head is put into gingival sulcus conveying drug, although needle point can be on the market
It is put into gingival sulcus but sharp syringe needle is not careful will puncture soft tissue, cause patient pain.Continuous nunchakus body product can not be put into greatly very much
In gingival sulcus, fineness is poor, wastes drug, therefore it is particularly necessary to design a kind of delivery head for meeting the conveying of gingival sulcus drug.This hair
Bright that delivery head is designed radian in pairs, be open linear flat slot, eliminates the needle pricked pain in patient's administration process, reaches nothing
Pain conveying purpose, delivery head conveying drug be it is linear, dose can be effectively controlled in operator, and delivery head radian is according to gum radian
It designs, drug can be accurately transported in gingival sulcus, no waste, one injection achievable tooth position side with facing radian
The conveying of drug, saves the time in 1/2 gingival sulcus.
Utility model content
The utility model relates to a kind of special painless gingival sulcus drug delivery heads, are applied to local anaesthetics, antibiosis in tooth gingival sulcus
The administration of the drugs such as element.
In order to solve the above technical problems, the technical solution of the utility model is:
A kind of special painless gingival sulcus drug delivery head.The utility model belongs to a kind of dental medical instrument, is applied to tooth
The administration of local anaesthetics, antibiotic etc in gingival sulcus.Including delivery head, needle tubing and needle stand.It is characterized in that, the delivery head
Material is flexible plastic or silica gel, and delivery head designs radian in pairs, and be open linear flat slot；The needle cannula material is flexible plastic,
Design has certain angle between needle tubing and needle stand, is helical structure in needle tubing, drug is made to reach buffering effect through helicoidal path conveying
Fruit；The needle stand material be duroplasts, needle stand be it is general, conventional syringe can be connected.
Preferably, above-mentioned special painless gingival sulcus drug delivery head, conveying head material are flexible plastic or silica gel, and needle tubing is soft modeling
Material, needle stand is duroplasts；The stimulation to gum can be effectively reduced.
Preferably, above-mentioned special painless gingival sulcus drug delivery head, conveying head shapes are double radians, and radian one is that imitative gum edge is raw
Radian is managed, angular range is 90 ° -180 °, and radian two is imitative facing physiologic radian, and angular range, which is 90 ° -180 °, (to be detailed in attached
Figure), the long 2-4mm of delivery head.
Preferably, above-mentioned special painless gingival sulcus drug delivery head, delivery head distal opening are linear flat slot.
Preferably, above-mentioned special painless gingival sulcus drug delivery head, design has certain angle between needle tubing and needle stand, is 90-
180 °, interior needle tubing is auger conveyor, and drug is made to reach buffering effect through helicoidal path conveying.
Preferably, above-mentioned special painless gingival sulcus drug delivery head, needle stand be it is general, conventional syringe can be connected
The utility model has the advantages that
The utility model can eliminate the needle pricked pain in Patient drug's transmission process, reach painless conveying drug
Purpose, delivery head conveying drug be it is linear, dose can be effectively controlled in operator, and delivery head radian is according to gum edge radian and facing arc
It spends and designs, drug can be accurately transported in gingival sulcus, no waste, 1/2 gingival sulcus of one injection achievable tooth position side
The conveying of interior drug, saves the time.Generally speaking such special painless gingival sulcus drug delivery head can eliminate conventional administration method
When pain, and can accurately conduct drugs in gingival sulcus, save drug dose, while administration time can also be saved to save
Save the consultation time of patient.
