Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to portable pre-filled syringe protection device.
Background
At present, the conventional prefilled syringe is a medicament product which is filled with common medicaments and can be directly injected; but part of the medicament is not suitable for filling by adopting a pre-filled syringe; particularly, in the places of medium and large hospitals where centralized dispensing rooms are arranged, the syringes are dispensed to corresponding patients after the syringes are used for dispensing; in the process of rotating the injector shaft with the medicine, under the condition that the push rod is not protected, the dosage of the medicine can be changed due to the problems of collision and the like in the measuring range, and the diagnosis and treatment effect of a patient is influenced.
Disclosure of Invention
The invention aims to solve the problems and provides a portable pre-filled syringe protection device;
a portable pre-filled syringe protection device comprising: a barrel sleeve 1 and a push rod sleeve 2;
the pipe barrel sleeve 1 is a hollow pipe with one end provided with a plug, and the other end of the pipe barrel sleeve 1 is provided with a connecting part 11; the connecting part 11 is provided with two opening parts 12, and the two opening parts 12 are oppositely arranged;
the push rod sleeve 2 is a hollow round pipe with one end provided with a plug; the other end of the pipe barrel sleeve 1 is provided with an external thread connecting port 21; the external thread connecting port 21 is in thread locking connection with the connecting part 11.
The inner side of the connecting part 11 is provided with locking internal threads 13; the lower part of the locking internal thread 13 is provided with a spigot edge 14.
The pipe body of the pipe barrel sleeve 1 is a polygon.

Detailed Description
Referring to fig. 1 to 4, a portable pre-filled syringe protection device includes: a barrel sleeve 1 and a push rod sleeve 2;
the pipe body of the pipe barrel sleeve 1 is a polygon, one end of the pipe barrel sleeve 1 is a hollow pipe with a plug, and the other end of the pipe barrel sleeve 1 is provided with a connecting part 11;
the connecting part 11 is provided with two opening parts 12, and the two opening parts 12 are oppositely arranged; the inner side of the connecting part 11 is provided with locking internal threads 13; the lower part of the locking internal thread 13 is provided with a spigot edge 14;
the inner side of the spigot edge 14 is in clearance fit with the syringe barrel;
the fall between the end surface of the spigot edge 14 and the end surface of the gap part 12 is the thickness of the pipe lug finger handle 33;
the connecting part 11 is formed by oppositely arranging two quarter pipe diameters, and the connecting parts 11 formed by the two opening parts 12 and the two quarter pipe diameters are arranged in a crisscross manner;
the push rod sleeve 2 is a hollow round pipe with one end provided with a plug; the other end of the pipe barrel sleeve 1 is provided with an external thread connecting port 21;
the external thread connecting port 21 on the push rod sleeve 2 is screwed and locked in the connecting part 11; after locking, the bottom edge of the external thread connecting port 21 is abutted against the spigot edge 14;
the use method comprises the following steps:
the hospital pharmacy inserts a pre-injection syringe tube 32 with a medicine prepared by a patient into the tube sleeve 1, and a tube ear finger handle 33 of the syringe is clamped at the notch part 12; then the push rod sleeve 2 and the tube barrel sleeve 1 are screwed and locked, and after the push rod sleeve 2 is screwed tightly, the bottom edge of the external thread connecting port 21 is abutted against the spigot edge 14; the motion range of the tube ear finger handle 33 is limited between the end part of the external thread connecting port 21 and the notch part 12, thereby protecting the syringe needle 31 and the syringe push rod 34; prevent the pollution and the medicine loss caused by mistakenly touching the syringe; the polygonal design of the barrel housing 1 also prevents the portable pre-filled syringe protection device from sliding and rolling off on a table top.
