Problems solved by technology

[0002] At present, the ointment medicines all use an open tube head of an ordinary hose. During use, the medicine that is squeezed out of the nozzle is unavoidable, and it is sucked back into the tube after contacting the air and the skin of the user. There may be hidden dangers of bacterial infection in the tube; the open tube head and the common material with high oxygen transmission rate provide sufficient oxygen for the bacteria entering the tube to multiply, which can easily promote the bacteria's reproduction and reduce the safety performance of the drug.
The longer the drug storage period and the more times it is used, the higher the probability of unsafe performance

Embodiment 1

[0012] Embodiment 1: According to figure 1 , the inner plug 3 of the present invention is an inverted umbrella-shaped inner plug, the height of the inverted umbrella-shaped inner plug umbrella rod can control the amount of ointment used, and the inner plug 3 is customized according to the requirements of different ointment dosages each time, so as to control each ointment. Squeeze out the dose at a time to ensure the safety of medication. In the present invention, under the pressure of the extruded hose, the anti-suckback inner plug support is raised, and the medicine is extruded accordingly; After blocking, after the ointment flows out from the anti-suckback tip, the inner plug automatically falls back to seal the ointment outlet hole of the support.

Embodiment 2

[0013] Embodiment 2: According to figure 2 , the inner plug of the present invention is an inverted "T" shaped inner plug, and its function and principle are the same as those in Example 1 to ensure the safety of medication.

Abstract

The backflow-preventing medical hose joint includes one hose joint and one ointment outlet hole. The hose joint consists of acute tip, inner stopper and seat connected to the hose. Unlike available ointment holding medical hose, which may have the squeezed out ointment withdrawn into the hose after contacting air and the skin of the user to cause bacterial infection, the present invention can avoid backsiphon to ensure medicine safety.

Description

technical field [0001] The invention relates to a medical hose, in particular to a medical anti-suction hose head. Background technique [0002] At present, the ointment medicines all use an open tube head of an ordinary hose. During use, the medicine that is squeezed out of the nozzle is unavoidable, and it is sucked back into the tube after contacting the air and the skin of the user. There may be hidden dangers of bacterial infection in the tube; the open tube head and the ordinary material with high oxygen transmission rate provide sufficient oxygen for the bacteria entering the tube to multiply, which can easily promote the breeding of bacteria and reduce the safety performance of the drug. The longer the drug storage period and the more times it is used, the higher the probability of unsafe performance. Contents of the invention [0003] The purpose of the present invention is to overcome various disadvantages caused by the open tube head used in the existing ointme...
