Abstract

The utility model discloses a novel Murphy dripper infusion device comprising a Murphy dripper. A lower tube is connected with the lower portion of the Murphy dripper. A sealing floater matched with an upper end opening of the lower tube is arranged in the Murphy dripper. When infusion is conducted, the sealing floater can float in liquid of an inner cavity of the portion, with the large diameter, of the Murphy dripper, meanwhile is controlled by a pulling line and upward floating of the sealing floater is limited by a support and a convex edge. When liquid medicine goes down and no liquid medicine above the sealing floater can be dripped, the sealing floater can go down along with the liquid medicine and timely seal an upper opening of the lower tube. Therefore, air is prevented from entering the human body when pressurized infusion is conducted, and the possibility of air embolism is thoroughly avoided. The liquid medicine is prevented from flowing to the portion below the Murphy dripper. The undesirable phenomenon that the liquid medicine is discharged outwards due to incorrect infusion is avoided, and therefore the physical and psychological health of a patient, medical care personnel and accompanying people is guaranteed. The phenomena that blood returning occurs and a needle is blocked due to the fact the liquid medicine liquid drops excessively are avoided. The structure is simple.

Description

New-type luxuriant luxuriant and rich with fragrance dropper infusion set
Technical field
This utility model relates to a kind of hospital medical apparatus commonly used, particularly a kind of new-type luxuriant luxuriant and rich with fragrance dropper infusion set.
Background technology
Infusion set is the indispensable utensil of being infused to the patient, normally utilizes luxuriant luxuriant and rich with fragrance dropper infusion set to be infused.Existing luxuriant luxuriant and rich with fragrance dropper infusion set includes the luxuriant luxuriant and rich with fragrance dropper of one section diameter chap, and bottom is connected with the lower pipe of loading liquid.During transfusion, particle size part inner chamber has the liquid level of medicinal liquid to show, to mean transfusion state.The transfusion device of this structure has following shortcoming: the one, and when pressure transfusion, air is easy to enter human body, may produce the phenomenon of air embolism; The 2nd, while changing liquid, particularly during the medicine of some chemotherapy of infusion and zest, high volatility, often can find that liquid has flow to luxuriant luxuriant and rich with fragrance dropper following, need in case of necessity the nurse that liquid is discharged to outside, so not only wasted medicine, not only can not guarantee to input the dose in patient body, produce unnecessary medical tangle, but also pollute the environment, will be with active drug exposure in air, patient, medical personnel, entourage's health is exerted an influence; The 3rd, the blood back phenomenon easily appears.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, prevent gas enter human body, change medicinal liquid smooth and easy, process without effluxing medicinal liquid the new-type luxuriant luxuriant and rich with fragrance dropper infusion set that transfusion improper point, anti-return blood phenomenon occur, overcome the deficiencies in the prior art.
New-type luxuriant luxuriant and rich with fragrance dropper infusion set of the present utility model, comprise luxuriant luxuriant and rich with fragrance dropper, is connected with lower pipe below luxuriant luxuriant and rich with fragrance dropper, in described luxuriant luxuriant and rich with fragrance dropper, is provided with the sealing float matched with lower pipe upper port.
New-type luxuriant luxuriant and rich with fragrance dropper infusion set of the present utility model, the upper end of wherein said lower pipe stretches to the inner chamber of luxuriant luxuriant and rich with fragrance dropper, and described sealing float is tabular or spherical.
New-type luxuriant luxuriant and rich with fragrance dropper infusion set of the present utility model, the upper port place periphery of wherein said lower pipe has the flange of turnup laterally, and flange and described sealing float match.
New-type luxuriant luxuriant and rich with fragrance dropper infusion set of the present utility model, an end of the bottom centre position of wherein said sealing float and bracing wire joins, and the other end and the support of bracing wire join, and in the inboard of lower pipe, are provided with chimb, and described support is positioned at the below of chimb.
New-type luxuriant luxuriant and rich with fragrance dropper infusion set of the present utility model seals the float floatability in the medicinal liquid of luxuriant luxuriant and rich with fragrance dropper particle size part inner chamber when transfusion, and is controlled by bracing wire, by support and chimb restriction floating.When the liquid medicine descends, top is during without lower of medicinal liquid, and the sealing float can descend with medicinal liquid, and pipe suitable for reading under timely shutoff.While having prevented pressure transfusion, air enters the generation of human body phenomenon, has thoroughly avoided the possibility of air embolism, especially rescuing and curing the wounded in enormous quantities, more applicable in the insufficient operation process of medical personnel.Can avoid liquid to flow to luxuriant luxuriant and rich with fragrance dropper following, without processing because of the improper bad phenomenon that effluxes medicinal liquid that causes of infusing, guaranteed patient, medical personnel, entourage's physical and mental health while particularly the medicine of some chemotherapy of infusion and zest, high volatility being changed to liquid.Avoid liquid to descend and excessively cause blood back, obstruction syringe needle phenomenon to occur, there are characteristics simple in structure simultaneously.
The accompanying drawing explanation
Fig. 1 is the structural representation of this utility model specific embodiment 1;
Fig. 2 is the structural representation of this utility model specific embodiment 2.
The specific embodiment
As shown in Figure 1: 1 is luxuriant luxuriant and rich with fragrance dropper, is connected with lower pipe 4 below luxuriant luxuriant and rich with fragrance dropper 1, is provided with the sealing float 7 matched with lower pipe 4 upper port in luxuriant luxuriant and rich with fragrance dropper 1.The upper end of lower pipe 4 stretches to the inner chamber of luxuriant luxuriant and rich with fragrance dropper 1, and sealing float 7 is tabular or lamellar, as long as can carry out shutoff to lower pipe 4 when sealing float 7 drops on lower pipe 4 upper port.For sealing preferably, at the upper port place of lower pipe 4 periphery, the flange 3 of turnup is laterally arranged, flange 3 matches with sealing float 7.The bottom centre position of sealing float 7 and an end of bracing wire 2 join, and the other end of bracing wire 2 and support 5 join, and in the inboard of lower pipe 4, are provided with chimb 6, and support 5 is positioned at the below of chimb 6.
Seal float 7 floatabilitys in the medicinal liquid of luxuriant luxuriant and rich with fragrance dropper 1 particle size part inner chamber when transfusion, and controlled by bracing wire 2, by support 5 and chimb 6 restriction floatings.When the liquid medicine descends, top is during without lower of medicinal liquid, and sealing float 7 can descend with medicinal liquid, and under shutoff in time, manage 4 suitable for reading.While having prevented pressure transfusion, air enters the generation of human body phenomenon, has thoroughly avoided the possibility of air embolism.Can avoid liquid to flow to luxuriant luxuriant and rich with fragrance dropper following, without processing because of the improper bad phenomenon that effluxes medicinal liquid that causes of infusing, guarantee patient, medical personnel, entourage's physical and mental health.Avoid liquid to descend and excessively cause blood back, obstruction syringe needle phenomenon to occur.
As shown in Figure 2: be to seal float 7 for spherical shape with above-mentioned difference, match with the upper port of lower pipe 4.When spherical sealing float 7 falls to the upper port of lower pipe 4 with liquid level, but manage 4 under shutoff.
