Abstract
The utility model discloses an intravenous infusion apparatus which consists of an intravenous infusion needle, an infusion tube, a drip cup and a bottle inserting needle, wherein the intravenous infusion needle is connected with a lower infusion tube; the lower infusion tube is provided with a speed controller for controlling the liquid flow rate and is connected with the drip cup; the drip cup is connected with an upper infusion tube; the bottle inserting needle is arranged at the front end of the upper infusion tube so as to connect an infusion bottle; the lower part of the drip cup is in a conical shape; a floating ball is arranged in the drip cup; the floating ball is a cone of which the diameter-height ratio is the same as that of the lower part of the drip cup; and after complete infusion of the liquid medicine, the floating ball settles to block the orifice of the lower infusion tube, and the infusion is automatically stopped so as to prevent the air from entering the lower infusion tube and even the blood vessel.
Description
Technical field
This utility model relates to medical apparatus and instruments, specifically is used for the transfusion device of venous transfusion.
Background technology
Intravenous transfusion device is comprised of venoclysis needle, tube for transfusion, a kettle and needle for inserting bottle, venoclysis needle connects lower tube for transfusion, and the speed regulator of control flow rate of liquid is arranged on the lower tube for transfusion, and lower tube for transfusion connects a kettle, drip kettle and connect upper tubing, the upper tubing front end has needle for inserting bottle in order to connect infusion bottle.The common many bottle liquid medicines of infusion process are continuous, the nursing staff needs often to observe medicine bottle so that when medicinal liquid just is totally lost, needle for inserting bottle is inserted into the new medicine bottle that medicinal liquid is housed, sometimes not careful, after being totally lost, medicinal liquid do not find, air has just entered tube for transfusion, if when changing medicine bottle the air in the tube for transfusion is sent into accidents such as causing angiemphraxis in the blood vessel, so should or change intravenous transfusion device with the Bas Discharged tube for transfusion in the tube for transfusion.
Summary of the invention
The purpose of this utility model provides a kind of air that prevents and enters the intravenous transfusion device of lower tube for transfusion and even intravasation.
Intravenous transfusion device of the present utility model is comprised of venoclysis needle, tube for transfusion, a kettle and needle for inserting bottle, venoclysis needle connects lower tube for transfusion, the speed regulator that the control flow rate of liquid is arranged on the lower tube for transfusion, lower tube for transfusion connects a kettle, drip kettle and connect upper tubing, the upper tubing front end has needle for inserting bottle in order to connect infusion bottle, drips the kettle bottom and is conical, and dripping in the kettle has ball float.
Preferably, ball float is cone, and its diameter aspect ratio is identical with the bottom of dripping kettle.
The tube for transfusion mouth of pipe under this utility model ball float sedimentation after medicinal liquid is totally lost is stopped up, transfusion stops automatically, prevents that thus air from entering lower tube for transfusion even intravasation.
Description of drawings
Fig. 1 is a kind of embodiment schematic diagram of this utility model.
Fig. 2 drips the kettle cutaway view.
The specific embodiment
Shown in Figure 1, intravenous transfusion device is comprised of venoclysis needle 1, lower tube for transfusion 2, upper tubing 3, a kettle 4 and needle for inserting bottle 5, venoclysis needle 1 connects lower tube for transfusion 2, the speed regulator 6 that the control flow rate of liquid is arranged on the lower tube for transfusion 2, lower tube for transfusion 2 connects a kettle 4, drip kettle 4 and connect upper tubing 3, upper tubing 3 front ends have needle for inserting bottle 5 in order to connect infusion bottle.
Shown in Figure 2, the bottom of dripping kettle 4 is conical, drip in the kettle 4 cone shape ball float 7 is arranged, these ball float 7 diameter aspect ratios are identical with the bottom of dripping kettle 4, because ball float weight is little, coupling by ball float and a kettle lower shape increases contact surface, the mouth of pipe of tube for transfusion 2 under the air pressure adequate closure of tube for transfusion fluid column under utilizing after transfusion is finished.
Claims (2)
1. intravenous transfusion device, formed by venoclysis needle, tube for transfusion, a kettle and needle for inserting bottle, venoclysis needle connects lower tube for transfusion, the speed regulator that the control flow rate of liquid is arranged on the lower tube for transfusion, lower tube for transfusion connects a kettle, drips kettle and connects upper tubing, the upper tubing front end has needle for inserting bottle in order to connect infusion bottle, it is characterized in that, described kettle bottom is conical, and dripping in the kettle has ball float.
2. described transfusion device according to claim 1 is characterized in that, described ball float is cone, and its diameter aspect ratio is identical with the bottom of dripping kettle 4.
