Summary of the invention
The purpose of this utility model is exactly will solve that traditional injection Nasal feeding device is difficult to inject thickness food, can only uses once, the nasal feeding flexible pipe easily comes off and the problem such as the food cooling is too fast, and a kind of injection Nasal feeding device that can overcome preferably defects is provided.
Concrete scheme of the present utility model is: improve for traditional Nasal feeding device, it is comprised of syringe and nasal feeding flexible pipe, and this syringe has injection tube, and the head of injection tube is provided with injection nozzle, be provided with discharging opening in the injection nozzle, cooperate in the injection tube piston and piston rod are housed; Nasal feeding flexible pipe one end is provided with joint and cooperates installation with injection nozzle; It is characterized in that: the end of described injection nozzle is provided with three positioning tooths, and three positioning tooths are 120 ° of angles to be arranged, forms three locating slots between three positioning tooths; The inside of joint is provided with inner chamber, inner chamber one end and nasal feeding soft pipe connection, other end sidewall is provided with three briar tooths that point to the inner chamber axis, three briar tooths are 120 ° of angles and arrange, three briar tooths and three positioning tooth spiral-locks together, in the inner chamber by between an end of nasal feeding flexible pipe and the injection nozzle rubber seal being housed.
In order to make syringe of the present utility model can carry out high-temperature sterilization, realize Reusability, save patient's expense, the syringe in this utility model adopts the epoxide resin type syringe, and the epoxide resin type syringe can high temperature resistant, antioxidation.
In order to prevent that the food cooling is too fast to patient injection food the time, the barrel inside of injection tube described in this utility model is provided with vacuum chamber.
In order to make things convenient for thickness food inhalation syringe and to push the nasal feeding flexible pipe, this utility model is with the diameter D of discharging opening
1Inside diameter D with the nasal feeding flexible pipe
2All be designed to 4mm.
Food when finishing in order to prevent from injecting food in the nasal feeding flexible pipe flows backwards, and this utility model also is equipped with stop valve on the nasal feeding flexible pipe, in case injection food finishes, prevents that by closing stop valve the food in the nasal feeding flexible pipe from flowing backwards out.
This utility model can be realized being connected and separating of syringe and nasal feeding flexible pipe fast, and nasal feeding is hose connection firmly, and difficult drop-off can Reusability, and the food in the syringe is difficult for cooling, looked at by patient and medical personnel's parent.
