Abstract
The invention relates to a safe needle head, comprising a limiting cannula, the middle of which is provided with a clamping channel used for tightly clamping the needle head. By muff coupling of the limiting cannula at the front end of the medal needle head, the length of the limiting cannula can be set differently for patients at different stages of the life cycle, the safe needle head effectively prevents the problem of too long needle head piercing, improves the experience of seeking medical advice, and makes improvements in the doctor-patient relationship to some extent; in addition, as the limiting cannula adopts an elastic component, the safe needle head has excellent resilience, and thus the needle head is convenient to pull out or take down. According to the design, the safe needle head is suitable for large-scale promotion.
Description
Technical field
The present invention relates to a kind of technical field of medical instruments, more particularly, to a kind of safety needle.
Background technology
Syringe is a kind of common medical instruments, uses very frequent as medicine equipment.Injection needle is by using function
Injection needle and transfusion needle can be divided into.During use, by penetrating in the patient the metal needle part of front end of the syringe needle, it penetrates
Depth relies on the operating experience of medical worker.This is for the practice medical worker lacking practical experience is difficult control.In addition, pin
Patient to different age group, it is also different that its syringe needle penetrates depth, and subdivision all do not made by existing syringe needle, and this just makes
Become, the inconvenience of medical personnel's operation, there is potential safety hazard；Reduce the experience of seeking medical advice of patient simultaneously, be unfavorable for doctors and patients pass of furthering
System.
Content of the invention
For the present situation of above-mentioned prior art, the technical problem to be solved is to provide a kind of simple operation,
Safe and reliable safety needle.
The technical scheme that present invention solution above-mentioned technical problem is adopted is: a kind of safety needle, including limit casing, institute
State the clamping channel being provided with the middle part of limit casing for clamping syringe needle.
Further, described limit casing bottom is provided with flange, between described end face of flange and the cross section of limit casing
It is provided with angle, the working face penetrating for different syringes, it is provided with different angles, realize completely docile.
Further, described clamping channel porch is provided with positioning convex, and described positioning convex upper end caliber is more than syringe needle
Caliber, its lower end caliber is less than syringe needle caliber, install convenient, simultaneously facilitates clamping needle.
Further, described limit casing bottom is provided with horn mouth, and described loudspeaker discharge surface is provided with least one through hole, loudspeaker
Mouth improves the contact comfort level with skin for the limit casing, and has good anti-pressure ability, arranges through hole on horn mouth, prevents
Only horn mouth and skin form negative pressure of vacuum.
Further, described limit casing adopts flexible member, improves the comfortableness that limit casing is contacted with skin, also just
Reset in syringe needle.
Compared with prior art, the invention has the beneficial effects as follows: the present invention pass through metal needle front end be socketed stop collar
Pipe, limit casing arranges different length according to the patient of different age group, is effectively prevented syringe needle and penetrates long problem, carries
Height is sought medical advice experience, improves doctor-patient relationship to a certain extent；Further, since limit casing adopts flexible member, have good
Restoring force, is easy to syringe needle and chooses.The present invention designs, suitable large-scale promotion.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the skill embodiment in the embodiment of the present invention, rather than all
Embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art institute under the premise of not making creative work
The every other embodiment obtaining, broadly falls into the scope of protection of the invention.
Embodiment 1
As shown in figure 1, a kind of described safety needle, including limit casing 2a, be provided with the middle part of described limit casing 2a for
The clamping channel 1a of clamping syringe needle.Described limit casing 2a adopts flexible member, and what raising limit casing 2a was contacted with skin relaxes
Adaptive, also allows for the reset of syringe needle.
For meeting the use of different age group patient, the limit casing 2a length specification of the present invention can arrange multistage, to reach
To most preferably penetrating depth, improve experience of seeking medical advice.
Embodiment 2
As shown in Fig. 2 the present embodiment is on the basis of embodiment 1, it is provided with flange 2b, institute in described limit casing 1b bottom
State and be provided with angle α between flange 2b end face and the cross section of limit casing 1b, for different syringes, such as: injection needle and defeated
The working face penetrating of liquid pin is different, is provided with different angle α, realizes completely docile.
Embodiment 3
As shown in figure 3, on the basis of being originally implemented in embodiment 1, being provided with positioning convex in described clamping channel 1c porch
2c, described positioning convex 2c upper end caliber be more than syringe needle caliber, its lower end caliber be less than syringe needle caliber, install convenient, simultaneously just
In clamping needle, improve structural stability.
Embodiment 4
As illustrated in figures 4-5, on the basis of being originally implemented in embodiment 1, it is provided with horn mouth 2d in described limit casing 1d bottom,
The lower pressure of buffering, and increase the contact area with patient skin, improve comfortableness, there is good anti-pressure ability, just simultaneously
In pulling out pin；Described horn mouth 2d surface is provided with least one through hole 3d, arranges through hole 3d, prevent horn mouth and skin on horn mouth
Skin forms negative pressure of vacuum.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of the spirit or essential attributes of the present invention, the present invention can be realized in other specific forms.Therefore, no matter
