Abstract
The utility model is related to the clamping channel being provided with the middle part of a kind of safety needle, including limit casing, the limit casing for clamping syringe needle.The utility model sets different length by being socketed limit casing, limit casing in metal needle front end according to the patient of different age group, is effectively prevented the problem of syringe needle penetrates long, improves experience of seeing a doctor, improves doctor-patient relationship to a certain extent；Further, since limit casing uses flexible member, with good restoring force, it is easy to syringe needle to choose.The utility model is designed, and is adapted to large-scale promotion.
Description
Technical field
The utility model is related 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, is used as medicine equipment very frequent.Injection needle is by using function
Injection needle and transfusion needle can be divided into.In use, by the way that the metal needle part of front end of the syringe needle is penetrated in patient's body, it is penetrated
Depth relies on the operating experience of medical worker.This is for the practice medical worker for lacking practical experience is difficult control.In addition, pin
To the patient of different age group, it is also different that its syringe needle penetrates depth, and existing syringe needle does not make subdivision, and this just makes
Into the inconvenience of medical personnel's operation has potential safety hazard；The medical treatment experience of patient is reduced simultaneously, is unfavorable for doctors and patients pass of furthering
System.
Utility model content
In view of the above-mentioned state of the art, technical problem to be solved in the utility model is to provide a kind of operation just
Victory, safe and reliable safety needle.
The utility model solve the technical scheme that is used of above-mentioned technical problem for：A kind of safety needle, including stop collar
The clamping channel for clamping syringe needle is provided with the middle part of pipe, the limit casing.
Further, the limit casing bottom is provided between flange, the cross section of the end face of flange and limit casing
Provided with angle, the working face penetrated for different syringes, provided with different angles, is realized completely docile.
Further, the clamping channel porch is provided with positioning convex, and positioning convex upper end caliber is more than syringe needle
Caliber, its lower end caliber is less than syringe needle caliber, install convenient, while being easy to clamping needle.
Further, the limit casing bottom is provided with horn mouth, and the loudspeaker discharge surface is provided with least one through hole, loudspeaker
Mouth improves contact comfort level of the limit casing with skin, and with good anti-pressure ability, through hole is set on horn mouth, prevents
Only horn mouth forms negative pressure of vacuum with skin.
Further, the limit casing uses flexible member, improves the comfortableness that limit casing is contacted with skin, also just
In the reset of syringe needle.
Compared with prior art, the beneficial effects of the utility model are：The utility model passes through in metal needle front end sleeve
Connect limit casing, limit casing sets different length according to the patient of different age group, be effectively prevented syringe needle penetrate it is long
The problem of, experience of seeing a doctor is improved, improves doctor-patient relationship to a certain extent；Further, since limit casing uses flexible member, tool
There is good restoring force, be easy to syringe needle to choose.The utility model is designed, and is adapted to large-scale promotion.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, to the skill embodiment in the utility model embodiment, and
The embodiment being not all of.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creativeness
The every other embodiment obtained under the premise of work, belongs to the scope of the utility model protection.
Embodiment 1
As shown in figure 1, being provided with the middle part of a kind of safety needle, including limit casing 2a, the limit casing 2a is used for
The clamping channel 1a of clamping syringe needle.The limit casing 2a uses flexible member, and what raising limit casing 2a was contacted with skin relaxes
Adaptive, also allows for the reset of syringe needle.
To meet the use of different age group patient, limit casing 2a length specifications of the present utility model are settable multistage,
Depth is most preferably penetrated to reach, experience of seeing a doctor is improved.
Embodiment 2
As shown in Fig. 2 the present embodiment is on the basis of embodiment 1, flange 2b, institute are provided with the limit casing 1b bottoms
State and angle α is provided between flange 2b end faces and limit casing 1b cross section, for different syringes, such as：Injection needle and defeated
The working face penetrated of liquid pin is different, provided with different angle αs, realizes completely docile.
Embodiment 3
As shown in figure 3, this implementation is on the basis of embodiment 1, positioning convex is provided with the clamping channel 1c porch
2c, the positioning convex 2c upper ends caliber is more than syringe needle caliber, and its lower end caliber is less than syringe needle caliber, install convenient, while just
In clamping needle, structural stability is improved.
Embodiment 4
As illustrated in figures 4-5, this implementation is provided with horn mouth 2d on the basis of embodiment 1 in the limit casing 1d bottoms,
The lower pressure of buffering, and the contact area with patient skin is increased, comfortableness is improved, while there is good anti-pressure ability, just
In pulling out pin；The horn mouth 2d surfaces are provided with least one through hole 3d, and through hole 3d is set on horn mouth, horn mouth and skin is prevented
Skin formation negative pressure of vacuum.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
