Abstract
The utility model relates to a Murphy tube provided with an automatic exhaust device. An infusion tube and an infusion dropper are respectively connected at the upper end and the lower end of the Murphy tube which is internally provided with the automatic exhaust device that consists of a stream guide component and a liquid preventing air hood; a connecting column tightly connected with the stream guide component is arranged in the middle of the liquid preventing air hood; the upper section of the stream guide component takes on a slender shape, liquid guide grooves are arranged at two sides of the stream guide component, and the lower section of the stream guide component takes on a reversed funnel shape; and the bottom of the reversed funnel shape is in tight fit or integral with the lower opening of the Murphy tube, and the bottom surface of the reversed funnel shape is communicated with the infusion dropper. When liquid medicine flows into the Murphy tube from the infusion tube, the liquid medicine is blocked and shunt by the liquid preventing air hood so as to be scattered to the tube wall and the bottom of the Murphy tube, so that the liquid medicine is prevented from mixing with air to form bubbles; when air exists in the Murphy tube, the air can be discharged as quickly as possible, thus lowering the generating rate of the bubbles due to the mixing of air and liquid. By adopting the Murphy tube, working efficiency of nursing personnel is improved, and working strength is reduced; and the Murphy tube has the advantages of simple structure, easy manufacture, low cost and large scale production.
Description
Technical field
This utility model relates to a kind of Murphy tube, is specially the Murphy tube that development has automatic exhaust device.
Background technology
Existing Murphy tube 6 upper and lower tube for transfusion 7, the transfusion drip tubes 4 of connecing, before transfusion, or after the liquid in infusion bottle is totally lost, for preventing that the air admission blood vessel in the Murphy tube from causing malpractice, routine operation is, or Murphy tube is inverted, discharge air wherein, or Murphy tube given a discount the upper end clamp, and hold in hands, discharge gas by syringe needle.For preventing the generation of this type of accident, existing " a kind of Murphy tube " (China Patent No. 2005200814650.0) with inner guide, top at Murphy tube has upper conduit, the bottom has downcomer, last downcomer is communicated with the inner chamber of Murphy tube by the liquid hole, it is characterized in that in Murphy tube, having a location guide, on guide rod, cooperate a valve plate.After the liquid in the infusion bottle dripped off, valve plate fell along inner guide, and downcomer is sealed, air is isolated, stop transfusion, after the liquid bottles that more renews, operation routinely only needs downcomer is pushed, makes valve plate overcome initial pressure and can proceed transfusion.It still needs artificial aerofluxus.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide a kind of air that can discharge fast in the Murphy tube, improves nursery work person's work efficiency; reduce working strength; the energy large-scale production, production cost is low, the Murphy tube that automatic exhaust device is arranged that is easy to assemble.
The implementation of this utility model purpose is, the Murphy tube that automatic exhaust device is arranged, upper and lower tube for transfusion, the transfusion drip tube of connecing of Murphy tube, automatic exhaust device is arranged in the Murphy tube, end shield blocking solution gas hood on the guiding subassembly of automatic exhaust device, have one and the close-connected joint pin of guiding subassembly in the middle of the blocking solution gas hood, the guiding subassembly epimere is a slender type, there are two symmetric guiding gutters both sides, guiding gutter passes to the top, hypomere is a upside down funnel shape, and the end opening of upside down funnel shape bottom and Murphy tube closely cooperates or is one, and the bottom surface is communicated with transfusion drip tube.
In clinical transfusion, when medicinal liquid flows into this utility model from tube for transfusion, the retardance and the shunting of blocking solution gas hood are arranged at first, make medicinal liquid scatter to Murphy tube tube wall and bottom, can not directly infiltrate guiding gutter, avoid medicinal liquid to mix and form bubble with air.When in the Murphy tube gas being arranged, utilize the surface tension of liquid and gravity to interact, can fast air be discharged as far as possible, reduce the probability that gas-liquid mixed produces bubble, improved nursery work person's work efficiency in the traditional infusion, reduced working strength.
This utility model is simple in structure, easy to manufacture, and cost is low, can large-scale production; Automatic exhaust device is supporting with traditional Murphy tube, easy to assembly again after both can having produced separately, also can directly produce an integral body.
Description of drawings
Fig. 1 is this utility model structural representation,
Fig. 2 is the automatic exhaust device structural representation.
The specific embodiment
With reference to Fig. 1,2, Murphy tube 6 upper and lower tube for transfusion 7, the transfusion drip tubes 4 of connecing, automatic exhaust device is arranged in the Murphy tube, have one and the close-connected joint pin 5 of guiding subassembly in the middle of the end shield blocking solution gas hood 1 on the guiding subassembly 2 of automatic exhaust device, blocking solution gas hood 1, the guiding subassembly epimere is a slender type, there are two symmetric guiding gutters 3 both sides, and guiding gutter passes to the top, and hypomere is a upside down funnel shape, upside down funnel shape bottom closely cooperates with the end opening of Murphy tube 6, and the bottom surface is communicated with transfusion drip tube 4.
The guiding subassembly epimere is a slender type, and there are two symmetric guiding gutters 3 both sides, and guiding gutter passes to the top, guiding gutter length is the 1/4-1/2 of guiding subassembly, be beneficial in the transfusion air in the Murphy tube be discharged as much as possible, reduce gas and the blended probability of medicinal liquid, reduce the possibility that bubble produces.
Hypomere is a upside down funnel shape, can reduce the air capacity in the Murphy tube.The end opening of upside down funnel shape bottom and Murphy tube 6 closely cooperates or is one, and the bottom surface is communicated with transfusion drip tube 4.
In clinical transfusion, when medicinal liquid flows into Murphy tube 6 from tube for transfusion 7, the retardance and the shunting of blocking solution gas hood 1 are arranged at first, make medicinal liquid scatter to Murphy tube tube wall and bottom, can not directly infiltrate guiding gutter, avoid medicinal liquid to mix and form bubble with air.
Along with medicinal liquid is assembled in the Murphy tube bottom, because there is certain distance bottom, guiding gutter 3 slits with guiding subassembly elongated segment bottom, when liquid level rises gradually, the very fast outflow of liquid that can not, and the meeting Compressed Gas, gas is discharged from guiding gutter 3 as far as possible, the blocking solution gas hood has also reflected the air-flow that rises simultaneously, accelerate gas and discharge, reduce gas and the blended probability of medicinal liquid from guiding gutter.
When beginning was flooded guiding gutter gradually bottom liquid level arrived guiding gutter, because the surface tension of liquid, liquid can not flow out from guiding gutter at once, when the gravity of liquid is increased to when being enough to overcome surface tension, owing to formed negative pressure in the Murphy tube, medicinal liquid is just directly discharged from guiding gutter fast, enters transfusion drip tube 4.
Whole process is because the effect of the automatic exhaust device in the Murphy tube has reached automatic vent and effectively prevented the effect that bubble produces.
