Infusion bottle plug puncturing device with dropping preventing function

Abstract

The invention discloses an infusion bottle plug puncturing device with a dropping preventing function. The puncturing device comprises an arrow-shaped puncturing needle, the puncturing needle comprises a needle tip which is used for puncturing into the infusion bottle, the needle tip is conical, the bottom of the needle tip is elliptical, a connecting pipe and a hand-held pipe sequentially extended from the lower end of the needle tip, the end, close to the connecting pipe, of the hand-held is provided with a baffle ring groove in the circumferential direction, a fixing ring is fixed to the interior of the baffle ring groove, the connecting pipe is sleeved with a connecting sleeve, a rubber sleeve is embedded to the part between the connecting sleeve and the connecting pipe, the connectingsleeve and the rubber sleeve are cylindrical, the end face of the connecting sleeve is elliptical and has the same size and shape with the bottom of the needle tip, a step-shaped baffle is arranged at the end, away from the connecting sleeve, of the needle tip, the other end of the step-shaped baffle fits the baffle ring, a transition pipe is in threaded connection with the end, away from the connecting pipe, of the hand-held pipe, the other end of the transition pipe is connected with an infusion pipe, a threaded hole is formed in the side face of the transition pipe, and an air inlet pipe which is used for balancing the external pressure of the infusion bottle is cooperatively arranged in the threaded hole.

Description

technical field [0001] The invention relates to a transfusion bottle stopper piercer, in particular to a transfusion bottle stopper piercer with the function of preventing falling off. Background technique [0002] Intravenous infusion is a common technical means in the medical industry at present. During the infusion process, only the infusion bottle or infusion bag is required to maintain a certain height difference from the patient's arm, and there is no restriction on the patient's posture. The infusion bottle moves slightly, and the entire infusion process lasts for a long time. Unintentional touch by the patient or others may cause the cork piercer inserted in the infusion bottle to fall off, causing blood back, polluting the cork piercer, and requiring medical staff to replace the infusion thong Re-infusion, even some patients or family members with weak safety awareness, will quickly reinsert the bottle stopper piercer that fell on the ground into the bottle to conti...

[0002] Intravenous infusion is a common technical means in the medical industry at present. During the infusion process, only the infusion bottle or infusion bag is required to maintain a certain height difference from the patient's arm, and there is no restriction on the patient's posture. The infusion bottle moves slightly, and the entire infusion process lasts for a long time. Unintentional touch by the patient or others may cause the cork piercer inserted in the infusion bottle to fall off, causing blood back, polluting the cork piercer, and requiring medical staff to replace the infusion thong Re-infusion, even some patients or family members with weak safety awareness, will quickly reinsert the bottle stopper piercer that fell on the ground into the bottle to continue the infusion, and enter the pollutants carried by the contaminated bottle stopper piercer into the vein. Unimaginable, therefore, it is particularly necessary to design a bottle stopper piercer that can prevent falling off during infusion
