Description
Technical field
This utility model belongs to syringe art, especially relates to a kind of disposable syringe.
Background technology
Cause for fear of reuse syringe at present infecting, the disposable syringes that use more, and existing disposable syringe, generally comprise hollow structure syringe, establish the syringe needle of syringe front end and be located at the push rod that can move forward and backward in syringe, and between syringe and syringe needle, be demountable structure, therefore a lot of people can change syringe needle for convenient, continue to use, cause undoubtedly the probability of cross infection, affect people's health; And syringe needle is not only thin but also long, is easily ignored by people, in use easily stabs user or people around, also can cause syringe needle bending because of shock; The pin cap being simultaneously enclosed within on syringe needle is easy to come off, not only dangerous, has also increased the probability infecting in moving process.
Utility model content
This utility model, in order to overcome the deficiencies in the prior art, provides one can avoid secondary to use, and strengthens the disposable syringe of safety in utilization.
To achieve these goals, this utility model by the following technical solutions: a kind of disposable syringe, comprise hollow syringe, be located at the push rod that can move forward and backward in syringe and be located at the needle component of syringe front end, the front end of push rod is sealing-plug; Described needle component comprises the card division that is arranged in syringe front end inside and the needle tubing that passes card division front end; Rear end, card division is extended a vertical inserting column vertically, and sealing-plug is provided with an inclination jack that can in the time that vertically inserting column inserts, needle component be tilted with vertical inserting column corresponding position; The outer inclination card being arranged with to vertical inserting column end tilts of described vertical inserting column, inclination jack inwall forms and can block inclination card and then needle component is pulled with push rod and enter the annular groove in syringe; The peripheral sheathed dismountable needle tube protecting sleeve of described syringe front end, the front end of this needle tube protecting sleeve is near needle tubing end, and the front end of this needle tube protecting sleeve is provided with an end cap sealing in the time that needle component enters syringe; The rear end inwall of described syringe forms the card section that anti-throw-out lever departs from syringe.Vertical inserting column and inclination jack are set, in vertical inserting column inserts inclination jack time, can make whole needle component tilt, and card is set and groove can make vertical inserting column be stuck in inclination jack, and then reach fixing of needle component and push rod, after a shot, while again pulling back push rod, can drive needle component to be moved in syringe backward together, and then avoid recycling, avoid cross infection, transmission of disease; Protective sleeve of syringe needle is set and makes the position of syringe needle more obvious, also form a circle guard circle in the periphery of syringe needle, in use can be more prone to notice syringe needle, also can reduce to encounter the probability of syringe needle, and then avoid being injured by syringe needle; And while using, need the degree of depth of acupuncture treatment can take protective sleeve of syringe needle when darker, and can be with this protective sleeve to use in the time that the acupuncture treatment degree of depth is more shallow, can select according to individual demand; Seal cover is set, also the Cotton Gossypii with blood samples of patients in use procedure can be put into afterwards to protective sleeve of syringe needle inner cap top cover labyrinth in use and further reach anti-dry effect of dying; Also can further stop that needle tubing gets out from front end simultaneously, improve the safety using; And card section can get out by further anti-throw-out lever in syringe, and then avoid needle component to get out from back end of syringe, further improved the safety using.
As preferably, the rear end of described syringe and the rear end of push rod radially extended spot convenient grip hold limit, this two sides of holding limit all forms anti-slip veins.Hold the limit person of being easy to use and grip, and anti-slip veins strengthens the stability and the skid resistance that use.
As preferably, described syringe comprises the canned paragraph being connected with needle component and the mobile section sliding for push rod, and the diameter of canned paragraph is less than the diameter of mobile section.This setting can be avoided, because thrust is excessive, needle component being released outside syringe, the liquid in syringe all being injected in patient body simultaneously.
As preferably, described push rod is decussation by the first push pedal and the second push pedal and forms, and described card section is for to extend to form rectangle blend stop by back end of syringe edge to the space between the first push pedal and the second push pedal.This arrange simple in structure, easily realize, and stop effective, and in the time that recovery personnel need to be isolated, just can be extracted without very large power, and can avoid separating with syringe because the reasons such as vibrations cause push rod after syringe use.
In sum, the utlity model has following advantage: vertically inserting column and inclination jack can make the fixing of needle component and push rod, while pulling back push rod, can drive needle component to be moved in syringe backward together, and then avoid recycling; Protective sleeve of syringe needle makes the position of syringe needle more obvious, has reduced to encounter the probability of syringe needle, and then avoids being injured by syringe needle.
