Abstract
An injector comprises an injection needle and a needle tube, wherein the injection needle is marked with calibrations which divide the injection needle into 8 sections from a first marked section to an eighth marked section from the needle point, and the length of each section is 5 mm, wherein the second marked section, the fourth marked section, the sixth marked section and the eighth marked section are marked with different colors respectively. Volume calibrations within 5 ml are included on the needle tube. The utility model has simple structure and convenient operation, which can be mastered with ease. In anaesthetizing the oral and maxillofacial region, the color calibrations on the injection needle can remind the operator the depth of the anesthesia. As a special injection needle fordental system and oral anesthesia, the injection needle can reach safely and precisely any part of the oral and maxillofacial region required to be injected, which can improve the effectiveness of anesthesia, reduce the pain of patient, lower effectively the number of medical accidents, and is safe, practical and convenient for popularization.
Description
Technical field
This utility model belongs to the oral device technical field, relates to a kind of syringe, is particularly useful for the syringe of oromaxillo-facial region anesthesia.
Background technology
At present, known syringe construction is by needle tubing, needle body, and needle body is made up of syringe needle socket and syringe needle.When carrying out oromaxillo-facial region corresponding site when anesthesia, syringe needle enters start injection anaesthetic behind the certain depth, thereby reaches the effect of anesthesia.But, used syringe needle is slick surface now, there is not scale, the operator generally is difficult to accurately estimate the degree of depth that syringe needle injects in when anesthesia, is especially carrying out crucial and special position such as infraorbital foramen when anaesthetizing, may be owing to operator's error, cause clinical accident, perhaps bring misery, make clinical manipulation become difficult, can not reach effective anaesthetic effect to patient.
Summary of the invention
Can not accurately arrive anesthesia position so that the insufficient shortcoming of anaesthetic effect safely in order to overcome existing entry needle, this utility model provides a kind of syringe needle that has the color scale chi, the color scale that syringe needle is marked with can play suggesting effect, can conveniently allow the operator accurately weigh inject the degree of depth at position.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of syringe, comprise injection needle and needle tubing, and this injection needle is marked with rule.
Further, distinguish between different scale area with color on this rule.
The scale of institute's labelling is divided into first marker field to the, eight marker fields that begun by needle point totally 8 segments with syringe needle on this injection needle, and the length of each marker field is 5mm.
Second marker field, the 4th marker field, the 6th marker field and the 8th marker field in described 8 segments are respectively by different color marks.
Come labelling second marker field, the 4th marker field, the 6th marker field and the 8th marker field with yellow, blue, green, black four kinds of colors, yellow marker field termination is represented 1cm, blue markings section termination is represented 2cm, and Green Marker section termination is represented 3cm, and density bullet section termination is represented 4cm.
Comprise 5ml on this needle tubing with interior volume markings.When the medical matters operator carried out oromaxillo-facial region anesthesia, the operator can read the degree of depth of being injected from the color scale on the syringe needle, when entry needle arrives the specified position and the degree of depth, can inject anaesthetic, guaranteed the effectiveness of anesthesia.If injection depth has exceeded normal range, then the expression injection is wrong, reminds the operator to adjust, and key position more should be watched out for, and to avoid malpractice, guarantees patient's life security.Save time, easy to use, reach safe and reliable purpose.
The beneficial effects of the utility model are, can be when carrying out oromaxillo-facial region anesthesia, and the degree of depth of accurately reading entry needle and being entered is anaesthetized the nerve at position, place effectively, avoids operator's error, and is clinical safe and reliable.Indicate graduated syringe needle, simple in structure, easy to use.
Description of drawings
Fig. 1 is syringe needle figure of the present utility model.
1. syringe needles among the figure, 2. syringe needle socket, 3. needle tubing, 4. needle tubing piston.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further specified.
In Fig. 1, syringe needle 1 and syringe needle socket 2
Syringe needle socket 2 joins with needle tubing 3 one ends, is inserted with needle tubing piston 4 in the needle tubing 3.
This injection needle 1 is marked with rule, and long 4cm has 8 segments, and every segment is 5mm.The scale of institute's labelling is divided into first marker field to the, eight marker fields that begun by needle point totally 8 segments with syringe needle on this injection needle, and the length of every segment is 5mm.
Second marker field 11, the 4th marker field 12, the 6th marker field 13 and the 8th labelling in 8 segments
14 respectively with different color marks.For example come labelling second marker field 11, the 4th marker field 12, the 6th marker field 13 and the 8th marker field 14 with yellow, blue, green, black four kinds of colors respectively, then yellow marker field 11 terminations are represented 1cm, the blue markings section 12 only locates to represent 2cm eventually, the representative of Green Marker section 13 terminations
Density bullet section 14 terminations are represented 4cm.Can certainly adopt other color or alternate manner district
Between scale area together, this does not give unnecessary details.
It is 5ml that needle tubing 3 is marked with volume markings.
Needle length is 3-4cm, and the needle tubing inner capacities is 5ml, and oromaxillo-facial region is anaesthetized the general degree of depth and is no more than
Injection anaesthetic consumption generally is no more than 4ml, and for guaranteeing anaesthetic effect, syringe needle is marked with the color scale chi, from 1cm to 4cm.In clinical, need the patient of row block anesthesia of inferior alveolar nerve more, when the row alveolus
When block anesthesia, according to writing about general syringe needle inserting needle 2.5cm injection in " oral and maxillofacial surgery "
Medicine 1-1.5ml anaesthetizes inferior alveolar nerve, and syringe needle retreats 1cm then, injection anaesthetic 1-1.5ml, anesthesia tongue
Warp, then syringe needle retreats 1cm again, injection anaesthetic 1-1.5ml, the anesthesia nervus buccinatorius, in this process I
The general degree of depth that is difficult to determine the syringe needle inserting needle, this brings puzzlement for effective anesthesia, also brings misery to the patient sometimes, and the color scale chi that the syringe needle of utility model is marked with, it is difficult clinically but can to solve
The problem of depth of needle can the handled easily personnel intuitively, accurately be found out the degree of depth that syringe needle enters like this,
Personal safety, the effectiveness of raising nerve anesthesia.
The above-mentioned description to embodiment is for ease of this
This utility model can be understood and use to the those of ordinary skill in art field.The person skilled in the art obviously can easily make various modifications to these embodiment, and the General Principle in this explanation is applied to
Among the embodiment and needn't pass through performing creative labour.Therefore, this utility model is not limited to the foregoing description,
Those skilled in the art answer for improvement and modification that this utility model is made according to announcement of the present utility model
Within the protection domain of the present utility model.
