Description
Technical field
The utility model relates to one of medical device research field needle inserter, especially a kind of disposable quick needle insertion
Device.
Background technique
Needle thorn, which refers to, is pierced into patient's body according to certain angle needle set (being often referred to acupuncture needle) under the guidance of theory of traditional Chinese medical science
It is interior, with it is twisted with mention the manipulations of acupuncture such as slotting come to human body privileged site carry out stimulation to achieve the purpose that treat disease.Needle
Piercing has distinct Chinese national culture and regional feature, is that the preciousness generated based on Chinese national culture and scientific tradition is lost
It produces.In recent years, since significant in efficacy, adverse reaction is few and without pharmacology toxic side effect, needle thorn gradually by the approval of the people of the world,
Acupuncture is also more and more extensive in clinical use.However, many patients can preferentially select other treatment side for the fear to needle
Formula, though the clinical householder method for having other quick needle insertions such as pipe needle, there are still inserting needle direction, depth to be difficult to the problems such as holding.
Utility model content
The purpose of this utility model is to provide a kind of disposable quick needle insertion device, can pass through the dynamics control of pressing
The compression degree of spring processed, and then control the depth of inserting needle.
The solution that the utility model solves its technical problem is: disposable quick needle insertion device, including shell, two press
Briquetting, needle body and spring, the shell include open end and closed end, and the briquetting is symmetrically mounted on shell by sliding rail
On, there is an inclined-plane in the inside of briquetting close to closed end location arrangements, limit space is formed between the inclined-plane of two briquettings,
The lower end of the sliding rail extends toward outside, and one end of the spring is fixed on the medial surface of closed end, and the other end of spring is direct
Or press and touch with the tail end of needle body indirectly, the tail end of needle body is located in limit space.
As a further improvement of the above technical scheme, auxiliary block is disposed between the spring and needle body tail end, it is described
The lower end surface of auxiliary block is located at needle body to be contacted, and the upper surface of auxiliary block is disposed with a mounting post, one end suit of the spring
In the outer surface of mounting post.
As a further improvement of the above technical scheme, the sliding rail includes straightway and segmental arc, the arc section
Below straightway, the segmental arc is the past outside extension in sliding rail.
As a further improvement of the above technical scheme, a fixture block, institute are disposed between the straightway and segmental arc
Stating fixture block is the protrusion for protruding 0.1~0.2mm of sliding rail.
As a further improvement of the above technical scheme, the shell includes upper casing and lower casing, the closed end and straight line
Section is located at upper casing, and the open end and segmental arc are located at lower casing.
As a further improvement of the above technical scheme, there are two window, the sliding rail positions for the side arrangement of the shell
In the two sides of the window, the two sides of the briquetting are disposed with the sliding slot to match with sliding rail.
The beneficial effects of the utility model are: the utility model passes through two briquettings of setting, in use, first driving pressing
After block is moved toward closed end, so that spring-compressed, after loosing one's grip, spring reset generates deformation power and makes needle body mobile toward open end,
After briquetting is moved to the outside along the lower end of sliding rail, the lower end spacing of limit space increases, and the tail end of needle body is empty from limit
Between be detached from, thus the head end of needle body from open end come out after be inserted into patient corresponding position.The utility model be suitable for quickly into
In the treatment of needle.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described.Obviously, described attached drawing is a part of the embodiment of the utility model, rather than complete
Portion's embodiment, those skilled in the art without creative efforts, can also be obtained according to these attached drawings it
His design scheme and attached drawing.
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation
It clearly and completely describes, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is a part of the embodiment of the utility model, rather than whole embodiments, it is based on the embodiments of the present invention, the skill of this field
Art personnel other embodiments obtained without creative efforts belong to the model of the utility model protection
It encloses.In addition, all connection/connection relationships being previously mentioned in text, not singly refer to that component directly connects, and referring to can be according to specific reality
Situation is applied, by adding or reducing couple auxiliary, to form more preferably coupling structure.
Referring to Fig.1, disposable quick needle insertion device, including 1, two briquetting 2 of shell, needle body 4 and spring 6, it is described outer
Shell 1 includes open end and closed end, and the briquetting 2 is symmetrically mounted on shell 1 by sliding rail 3, and the inside of briquetting 2 is close
