Abstract
The utility model discloses an air-intake-preventing infusion drip cup which comprises a drip cup body and a funnel-shaped flow guide part arranged in the drip cup body, wherein a floating body matched with an inner cavity of the funnel-shaped flow guide part is arranged at the upper part of the funnel-shaped flow guide part. The infusion bag has the advantages of being reasonable in design and simple in structure, air can be effectively prevented from entering a human body to form an air inlet air plug after liquid medicine in the infusion bag or the infusion bottle is dripped, infusion safety is guaranteed, and operation of a patient or a nursing staff is facilitated.
Description
Technical Field
The utility model relates to the technical field of infusion equipment, in particular to an air-intake-preventing infusion drip cup.
Background
The infusion apparatus is generally composed of a vein needle, an infusion hose, a liquid medicine filter, a flow rate regulator, a drip cup and an air filter of an air inlet pipe. The use principle is that under the action of atmospheric pressure, liquid in the bottle flows into the dropping funnel along a thin infusion hose, and when the pressure of a water column of the dropping funnel is greater than the venous pressure, the liquid in the bottle flows into veins along the hose.
As the transfusion time of the patient in the cardiovascular and cerebrovascular department is longer, the nursing person or the patient is easy to feel fatigue, once the liquid medicine is dripped, the nursing person is not in time to nurse or the patient is not found after sleeping, or the phenomenon of air inlet embolism occurs, thereby increasing the pain of the patient.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model aims to provide an air-intake-preventing infusion drip cup which is reasonable in design and simple in structure, can effectively prevent air from entering a human body to generate an air-intake air plug after liquid medicine in an infusion bag or an infusion bottle is completely dripped, ensures infusion safety, and is convenient for a patient or a nursing staff to operate.
An air-intake-preventing infusion drip cup comprises a drip cup body and a funnel-shaped flow guide part arranged in the drip cup body, wherein a floating body matched with the inner cavity of the funnel-shaped flow guide part is arranged at the upper part of the funnel-shaped flow guide part.
The funnel-shaped flow guide part is provided with a second flow guide part which is convenient for the floating body to enter the cavity of the funnel-shaped flow guide part.
A lower slotted hole is arranged below the funnel-shaped flow guide piece, and a clamping ball is arranged below the floating body.
The two lower slotted holes are symmetrically arranged below the funnel-shaped flow guide piece.
The lower slotted hole adopts four, and the equipartition is under infundibulate water conservancy diversion spare.
Compared with the prior art, the utility model has the following beneficial effects: the liquid in the bottle flows into the drip cup along the thinner transfusion hose, when the liquid inlet in the drip cup is higher than the funnel-shaped flow guide part, the floating body floats under the action of buoyancy, the liquid floating body in the drip cup can not be contacted with the funnel-shaped flow guide part, and the liquid can only flow into the lower transfusion tube from the funnel-shaped flow guide part (the cavity in the funnel-shaped flow guide part); when the liquid in the drip cup is lower than the funnel-shaped flow guide part, the floating body is contacted with the funnel-shaped flow guide part due to the action of gravity, the contact area is large, the sealing effect is good, and the phenomenon of air inlet air embolism cannot occur at the moment; more importantly: because the clamping ball is arranged below the floating body, the clamping ball is arranged below the funnel flow guide piece, the floating body floats, liquid flows into the liquid drainage pipe from the lower slotted hole, and the floating body is under the action of the clamping ball.
Drawings
The drawings described herein are provided to provide a further understanding of the present application:
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of the float of the present invention;
FIG. 3 is a schematic view of the structure A-A in FIG. 1.
Detailed Description
Embodiments of the utility model are disclosed below with the aid of the following figures:
example 1: as shown in figures 1-3, the infusion drip cup capable of preventing air intake comprises a drip cup 1 and a funnel-shaped flow guide part 4 arranged in the drip cup 1, wherein a floating body 3 matched with the inner cavity of the funnel-shaped flow guide part 4 is arranged at the upper part of the funnel-shaped flow guide part 4.
The difference between example 2 and example 1 is: the funnel-shaped flow guide part 4 is provided with a second flow guide part 2 which is convenient for the floating body 3 to enter the cavity of the funnel-shaped flow guide part 4.
The difference between example 3 and example 2 is: a lower slotted hole 6 is arranged below the funnel-shaped flow guide part 4, and a clamping ball 5 is arranged below the floating body 3.
The difference between example 4 and example 3 is: the number of the lower slotted holes 6 is two, and the two lower slotted holes are symmetrically arranged below the funnel-shaped flow guide piece.
Compared with the prior art, the utility model has the following beneficial effects: the liquid in the bottle flows into the drip cup along the thinner transfusion hose, when the liquid inlet in the drip cup is higher than the funnel-shaped flow guide part, the floating body floats under the action of buoyancy, the liquid floating body in the drip cup can not be contacted with the funnel-shaped flow guide part, and the liquid can only flow into the lower transfusion tube from the funnel-shaped flow guide part (the cavity in the funnel-shaped flow guide part); when the liquid in the drip cup is lower than the funnel-shaped flow guide part, the floating body is contacted with the funnel-shaped flow guide part due to the action of gravity, the contact area is large, the sealing effect is good, and the phenomenon of air inlet air embolism cannot occur at the moment; more importantly: because set up the card ball under the body, the card ball prevents that the body is unstable, and the card ball is under funnel water conservancy diversion spare, and the body floats, and liquid flows into the downcomer from lower slotted hole, because the effect body of card ball.
The above description is only an embodiment of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
