Abstract
The utility model discloses a fluid infusion control device, which comprises a Murphy's dropper body, wherein a large-diameter cylindrical cavity is formed in the middle part of the Murphy's dropper body; the bottom of the cylindrical cavity is provide with an N-shaped liquid channel; the liquid inlet of the N-shaped liquid channel is communicated with the cylindrical cavity; the liquid outlet of the N-shaped liquid channel is communicated with the dropper body on the lower part of the cylindrical cavity; liquid drops from the upper side of the cylindrical cavity, enters a liquid isolating cavity from the liquid inlet, flows out of the liquid outlet and enters the dropper body from a lower dropper orifice. When liquid in an infusion bottle or infusion bag is used up, a part of liquid is stored in the liquid isolating cavity under the blocking action of the left section of a lower liquid isolating sheet, so that automatic stopping of infusion is realized, and blood is prevented from flowing back. The fluid infusion control device has the characteristics of simple structure, low cost, high safety and easiness in machining.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of fluid infusion control device.
Background technology
At present, in the time giving patient infusion, generally use Mo Feishi dropper, liquid is entered in body under the effect of gravity, include stilligout, by-pass cock and Transfusion needle pipe, it utilizes stilligout and by-pass cock, can only control fluid flow and speed, it cannot make liquid in stilligout, stop for a long time, therefore, and in infusion process, need to someone nurse, prevent from not processing in time after liquid is totally lost and cause air to enter human body, or after infusion-completed, occurring a large amount of blood back phenomenons, thisly may cause life danger because pulling out not in time pin.Because current medical condition is limit, hospital conventionally has a lot of patients and infuses simultaneously, and medical personnel's quantity is few, can not process in time after will causing liquid to be totally lost and bring above-mentioned danger.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object that this utility model is adopted is to provide a kind of fluid infusion control device, have simple in structure, cost is low, the feature of safe and easy processing.
To achieve these goals, the technical solution adopted in the utility model is: a kind of fluid infusion control device, include Mo Feishi dropper body, be provided with a large diameter cylindrical cavity at Mo Feishi dropper body 1 middle part, be provided with N shape fluid passage in the bottom of cylindrical cavity, the inlet of N shape fluid passage is connected with cylindrical cavity, and the liquid outlet of N shape fluid passage is connected with the body of cylindrical cavity bottom.
Described N shape fluid passage by upper every liquid sheet and under fill the span of a man's arms and form every liquid sheet.
Described upper every liquid sheet and under be L shaped every liquid sheet, above be connected with cylindrical cavity left side wall every left section of liquid sheet, under be connected with cylindrical cavity bottom interior wall every right section of liquid sheet, under every right section of liquid sheet the top in lower nozzle, under be the left side of vertical direction in cylindrical cavity every left section of liquid sheet, upper every liquid sheet right section is the right side of vertical direction in cylindrical cavity, upper every right section of liquid sheet with under every formation between left section of liquid sheet every sap cavity body.
Described upper every right section of liquid sheet and under be inlet every the space between right section of liquid sheet.
Described upper every left section of liquid sheet and under be liquid outlet every the space between left section of liquid sheet.
Described upper every liquid sheet, under be less than the hardness of cylindrical cavity 2 every the hardness of liquid sheet.
The beneficial effects of the utility model are:
Due to this utility model in cylindrical cavity, be provided with by every liquid sheet and under every the liquid sheet N shape fluid passage forming of filling the span of a man's arms, mainly utilize siphon principle, after liquid is totally lost, in sap cavity body, stored partially liq, be used for stoping air to enter human body, can stop blood backflow simultaneously; Solve the problem that can not in time, automatically close after Mo Feishi dropper has been infused, there is feature simple in structure, with low cost, easy to operate and safe, be generally applicable to dropping bottle and drip bag.
Accompanying drawing explanation
