When the push rod is retracted, the rubber plug is pulled out of the tubular container due to the hook at the tip end and is fixed on the tip end, and the rubber plug can be taken down only by other instruments, which is very troublesome; furthermore, the plunger 20 cannot be held in place when it is retracted to the far left end of the barrel, so that the tip may slip off at any time and may be easily punctured by the user inadvertently.
SUMMERY OF THE UTILITY MODEL
In view of the above problems, the present application aims to provide a Bilanma injector for stomatology department, which can automatically withdraw the rubber plug; the application aims at providing a Billand hemp syringe for department of stomatology, which can fix the push rod when the push rod is withdrawn, and reduces the needle stick injury caused by the tip.
The utility model provides a Bilanma injector for department of stomatology, it includes barrel and push rod; an opening is formed in the side part of the cylinder body and used for loading a tubular container of the Bilastine injection, and a rubber plug is arranged at an opening in the rear end of the tubular container of the Bilastine injection; the front end of the push rod forms a tip with a hook; the tip is inserted into the barrel from an opening of the end head at the rear end of the barrel so as to pierce into the rubber plug;
the cylinder body is provided with two blocking pieces at the rear part, and the two blocking pieces are arranged in the cylinder body along the extending direction of the cylinder body; the first of the two baffle plates is arranged at the upper side of the cylinder body, and the second baffle plate is arranged at the lower side of the cylinder body, and the two baffle plates are opposite to each other and form a gap; the separation distance of the front ends of the two separation blades is larger than the size of the outer side outline of the tip of the push rod and smaller than the diameter of the rear end of the rubber plug, so that the tip of the push rod is allowed to pass through but the rubber plug can be blocked.
Preferably, the two blocking pieces are identical in shape and arranged in mirror symmetry.
Preferably, the front ends of the two blocking pieces form a right-angle or acute-angle bending part respectively.
Preferably, a magnet is arranged at the rear part of the tip end of the push rod, and the end head of the rear end of the barrel body is made of iron; when the push rod retracts to the rear end of the barrel, the magnet is attracted with the end head together.
By arranging the baffle plate on the barrel, the rubber plug combined on the tip can be blocked by the baffle plate and falls off from the tip in the process of retracting the push rod; when the push rod retreats to the rear end of the barrel body, the magnet at the rear part of the tip is attracted to the iron end head at the rear end of the barrel body, the tip is fixed and cannot slip off, and the accidental puncture is reduced.

Detailed Description
The oral cavity use Bilanma syringe of the present application will be described in detail with reference to the accompanying drawings.
The Bilanma injector for the department of stomatology comprises a cylinder body 10 and a push rod 20; an opening 12 is formed in the side of the cylinder 10 and used for loading a bluish dogbane injection liquid tubular container, and a rubber plug is installed at an opening in the rear end of the bluish dogbane injection liquid tubular container; the front end of the push rod 20 forms a tip 21 with a hook; the tip 21 is inserted into the barrel 10 from an opening in the end of the rear end of the barrel to pierce the plug.
The barrel 10 is formed with two blocking pieces 11 at the rear part thereof, and the two blocking pieces 11 are arranged in the barrel along the extending direction of the barrel 10; the first of the two baffle plates 11 is arranged at the upper side of the cylinder body 10, and the second baffle plate is arranged at the lower side of the cylinder body 10, and is opposite to each other and forms a gap; the distance separating the front ends of the two flaps 11 is greater than the size of the outside profile of the tip 21 of the pusher and smaller than the diameter of the rear end of the plug, so that it allows the tip 21 of the pusher 20 to pass but blocks the plug.
The two baffle plates 11 are identical in shape and are arranged in mirror symmetry.
The front ends of the two blocking sheets 11 form a right-angle or acute-angle bending part respectively.
A magnet 22 is arranged at the rear part of the tip 21 of the push rod 20, and the end head of the rear end of the barrel 10 is made of iron; when the plunger 20 is retracted to the rear end of the barrel 10, the magnet 22 is attracted to the tip.
When in use, the pushing process is the same as that of the Bilanma injector used in the department of stomatology in the prior art, and the description is omitted. When the push rod returns, the push rod passes through the gap between the baffle plates, but the rubber plug can be blocked, therefore, in the process of returning the push rod, the rubber plug can be retreated from the tip end of the push rod by the baffle plates, and other instruments are not required to be reused for taking down the rubber plug. When the push rod reaches the rear end of the barrel, the magnet at the rear end of the tip of the push rod is attracted with the end head of the rear end of the barrel, the push rod cannot slide in the opening of the end head, the tip cannot slide, and accidental puncture is avoided.
