Abstract
本实用新型提供了一种皮下注射专用的预灌封注射器，其包括玻璃外套、推杆、活塞、针、护帽，所述玻璃针管的前端设置有与针管贯通的短针，护帽套装于针头外且与针头外表面密闭配合。目前市场上常规的皮下注射器，注射角度为30‑45度，深度一般要求为针头的2/3，用户在使用过程中因为操作不正确容易造成重度疼痛或刺伤自己的风险，本实用新型即方便医护人员使用的同时，也降低用户自行注射的要求，可以任意角度直接注射，安全有效。
The utility model provides a special pre-filled syringe for hypodermic injection, which comprises a glass jacket, a push rod, a piston, a needle and a protective cap. Outside the needle and in a tight fit with the outside surface of the needle. The conventional hypodermic syringes currently on the market have an injection angle of 30-45 degrees, and the depth is generally required to be 2/3 of the needle. During use, the user may cause severe pain or risk of stabbing himself due to incorrect operation. It is convenient for medical staff to use, and it also reduces the requirement for users to inject themselves. It can be injected directly at any angle, which is safe and effective.
Description
Technical field
The utility model relates to a kind of medicament packaging container, specifically a kind of dedicated pre- encapsulating injection of subcutaneous injection
Device.
Background technique
Pre-encapsulated injector is a kind of novel drug packing material, it is directly loadable into liquid medicine in syringe and protects
It deposits, is equivalent to typical medicine packing container when storing drug, and be equivalent to common syringe when in use, when use is simple
It is convenient.Injector assembly generally comprises housing, piston, push rod, needle, and piston is mounted on push rod front, can be driven outside by push rod
It is twitched back and forth in set, needle installation is connected to housing front end, is equipped with silica gel helmet thereon.As pre-encapsulated injector, housing is
It is processed by glass tube, has good compatibility with drug, it in this way can be in order to long term storage liquid drug.
Glass cloth currently on the market does not have hour hand product, medical staff's use aspect is caused it is certain constant,
Medical staff's working efficiency can be improved in hour hand product, and user can also be used by simply training oneself, be not concerned about
Needle point is too long to stab oneself.
Utility model content
The purpose of this utility model is to solve user to be easy to stab oneself since needle point is too long in voluntarily use process, is mentioned
It for a kind of subcutaneous hour hand syringe of advantages of simple, can be used directly, avoid because operation is not professional to lead to malpractice.
The technical scheme in the invention for solving the above technical problem is: a kind of dedicated pre- encapsulating note of subcutaneous injection
The front end of emitter, including housing, push rod, piston, steel needle and helmet, housing is equipped with conehead, and steel needle is connected with conehead, push rod
Front end is equipped with piston, and piston is set to jacket internal, and helmet is set on conehead, before the steel needle front end and glass cloth conehead
The distance between end is 6-8mm, and steel needle is located inside helmet.
The steel needle length of the hypodermic needle of the prior art is mostly 20-25mm, and steel needle is easy to be pierced into muscle layer, and when use
Needle point and skin is needed to be pierced into 30-40 ° subcutaneous, general injection depth is 2/3rds of syringe needle to be advisable, and operates professional ratio
It is relatively strong.It is only 6-8mm that dedicated pre-encapsulated injector steel needle length, which is subcutaneously injected, in the utility model, and user can be without training
Instruction directly uses, in use, it is highly-safe, it can be pierced into muscle layer to avoid steel needle, so as to cause the generation of malpractice.
The distance between the steel needle front end and glass cloth conehead front end are 8mm.
The housing is glass cloth.
The helmet is glass helmet.
Glass cloth is conducive to long term storage liquid drug.
The length that dedicated pre-encapsulated injector steel needle is subcutaneously injected in the utility model is less than the length of prior art steel needle,
It can be used directly, not consider the angle and depth punctured, avoid because operation is not professional to lead to malpractice.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that dedicated pre-encapsulated injector is subcutaneously injected in the utility model
Fig. 2 is the structural schematic diagram of the housing of the utility model

Detailed description of the invention
1, helmet 2, steel needle 3, housing 4, push rod 5, conehead
Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of dedicated pre-encapsulated injector of subcutaneous injection, including housing 3, push rod 4, work
The front end of plug, steel needle 2 and helmet 1, housing 3 is equipped with conehead 4, and steel needle 2 is connected with conehead 5, and the front end of push rod 4 is equipped with piston,
Piston is set to inside housing 3, and helmet 1 is set on conehead 5, and the distance between 2 front end of steel needle and 3 conehead front end of housing are 6-
8mm, steel needle 2 are located inside helmet 1.
Further, the distance between 2 front end of steel needle and 3 conehead front end of housing are 8mm.
Housing 3 is glass cloth.Helmet 1 is glass helmet.
3 open rearward end of housing, wherein medical fluid can have been filled in advance, glass cloth is conducive to long term storage liquid drug.It pushes away
5 front end of bar installation connection piston, piston are packed into housing 3 after liquid drug, are used as the closure of 3 Chinese medicine liquid of housing simultaneously
Lid, piston can be slided and be sealed in housing 3, driven by push rod 5 and moved in glass cloth 3.
The utility model is characterized in that: being equipped with steel needle 2, exposed length 6-8mm on the housing 3.User is solved to exist
It voluntarily is easy to stab oneself since operation is not professional in use process, a kind of syringe of advantages of simple is provided, can be used directly,
Do not consider the angle and depth punctured, avoids because operation is not professional to lead to malpractice.
