Abstract
The utility model belongs to the pressure syringe apparatus technical field and relates to a disposable sterile syringe which comprises a needle tube, a plunger which is arranged in the needle tube, a plunger pole which is connected with the plunger, a convex platform which is connected with the plunger pole into a whole arraned on the plunger pole, and a separating layer is arranged between the rear end of the needle tube and the convex platform. The utility model does not pollute the plunger pole regardless of whether the medical peoples operate according to the operation rules, thus does not pollute the medicine liquids.
Description
This utility model belongs to the technical field of pressure infusion apparatus.
The disposable sterilized injector that present hospital uses, reduced the probability of happening of cross infection, can guarantee that by normal operations medicinal liquid is not contaminated when injecting, but at many bottles of injections of preparation, or the dosage of a shot is bigger, in the time of need taking out notes repeatedly with a needle tubing, be difficult to guarantee that medical personnel's hands can not touch the piston rod of syringe, and sometimes when medical personnel when accelerating operating rate, also can adopt and hold piston rod and take out notes fast, and piston rod to contact with needle interior wall, hold the piston rod operation if adopt, or careless hands runs into piston rod and will pollute needle interior wall, thereby also will pollute medicinal liquid.
The purpose of this utility model provides a kind of disposable sterilized injector that also can not pollute piston rod when irregular operation.
This disposable sterilized injector comprises needle tubing, the piston in needle tubing, and the piston rod that is connected with piston is provided with the boss that is connected as a single entity with piston rod on piston rod, be connected with sealing coat between the rear end of needle tubing and boss.
Owing between piston rod and syringe rear end, be connected with sealing coat, thereby make, thereby also just can not be with liquid medicine contamination no matter whether medical personnel by the rule of operation operation, can not pollute piston rod.
Accompanying drawing shows embodiment of the present utility model, wherein:
Front view cuts open in the office that Figure 1 shows that disposable sterilized injector;
Figure 2 shows that the right view of disposable sterilized injector;
Figure 3 shows that along the cutaway view of A_A line shown in Figure 1;
Disposable sterilized injector as shown in the figure comprises needle tubing 1, the piston 2 in needle tubing 1, the piston rod 3 that is connected with piston 2, pintle 7 with piston rod 3 is connected as a single entity is provided with the boss 5 that is connected as a single entity with piston rod 3 on piston rod 3, boss 5 is located at piston rod 3 and pintle 7 junctions.Rear end and 5 of boss at needle tubing 1 are connected with sealing coat 6.Be provided with the big boss 4 that is connected as a single entity with needle tubing 1 in the rear end of needle tubing 1.Sealing coat 6 is connected between big boss 4 and the boss 5.
