Description

Special manual injector for nasal feeding

Technical Field

The utility model relates to a manual injector, in particular to a manual injector special for nasal feeding.

Background

The nasal feeding tube is commonly used for patients who can not take food through mouth to ensure that the patients take enough nutrition, moisture and medicine, and the current clinical nasal feeding injector has the following defects and hidden danger of safe medication: firstly, a special manual nasal feeding injector is not provided, an intravenous injector is used instead of the nasal feeding injector, the intravenous and nasal feeding are easily mixed, and the nursing safety risk exists; the syringe has insufficient volume, the feeding liquid is pumped after the tube is repeatedly detached for many times, the working time and the working amount of nursing personnel are increased, and the syringe is easy to pollute; because the common injector is used for veins, the scales on the injector are fine and complex, the characters of the scales are small, the use of middle-aged and elderly people is influenced, the feeding of a patient is not enough or the nasal feeding liquid is excessive, the aspiration is caused, and the lung infection is caused; at present, a 30-degree crack is formed in a piston rod of the syringe needle, residues such as food or medicines are easy to remain in the crack and cannot be cleaned in the administration process, and the risk of intestinal infection is increased.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to provide the manual injector special for nasal feeding.

One of the purposes of the utility model is realized by adopting the following technical scheme:

special manual syringe of nasal feed, the novel nipple rectifier comprises a cylindrical shel, be provided with the scale mark on the lateral wall of barrel, the barrel inner chamber is provided with the piston, fixedly connected with push rod on the left side wall of piston, the push rod is circular setting, piston one end fixedly connected with plectane is kept away from to the push rod, fixedly connected with injection head on the right side wall of barrel, be provided with the valve on the injection head, the injection head is curved tapered setting, the injection head is close to barrel one side cross sectional area and is greater than its cross sectional area of keeping away from barrel one side.

Furthermore, five scale marks are uniformly distributed and arranged, and the scale marks sequentially comprise 20ML, 40ML, 60ML, 80ML and 100ML from right to left.

Furthermore, the cylinder, the push rod, the circular plate and the injection head are all arranged in green.

Further, the diameter of the circular plate is larger than the outer diameter of the cylinder.

Compared with the prior art, the utility model has the beneficial effects that:

1. the nasal feeding injector is designed to be green, thereby reducing the visual fatigue of nurses, being easy to instantly distinguish and use the injector and avoiding the mixed use in emergency;

2. the volume of the injector is increased to 100ml, the injector is separated from the size of the intravenous injector used clinically, the scales are changed to 20, 40, 60, 80 and 100ml, and the injector is thickened and enlarged, so that the injector is convenient for middle-aged and elderly people to use;

3. the injection head is a bent conical threaded connector, is favorable for being connected with nasal feeding tubes and nasointestinal tubes of various types, is not easy to fall off under the action of the threaded tubes after being connected, and is favorable for a nurse to save labor;

4. the valve is added in the injection head, when the nasal feeding process needs to be temporarily suspended or liquid food needs to be pumped again, the valve can be opened and closed at any time only by slightly pushing the piston valve by the left index finger and the rear index finger of an operator, so that air is prevented from entering the nasal feeding tube, liquid leakage and pollution increase during continuous injection are avoided, and the operation steps of a user can be reduced;

5. the size of the push rod is increased, so that the internal angle of the push rod is changed into a round shape, food and medicine residues are prevented from being left in the crack and cannot be cleaned, and intestinal infection is prevented from being increased.

The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented in accordance with the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more clearly understood, the following preferred embodiments are described in detail with reference to the accompanying drawings.
