Abstract
The utility model discloses a venous transfusion speed regulation device. A drip cup is internally provided with a conical body; the conical body is entirely or partly inserted into a transfusion tube at the lower part of the drip cup; an oblate cylindrical strainer is connected to the upper part of the conical body; the upper part of the strainer is provided with an arc-shaped flange; the inner side wall of the drip cup is provided with a plurality of radially symmetrical clamping blocks so as to clamp the arc-shaped flange at the upper part of the strainer; the strainer is clamped on the clamping blocks through the flange at the upper part of the strainer; the conical body is partly inserted into the transfusion tube at the lower part of the drip cup; and liquid medicine flows from a gap between the conical body and the transfusion tube. When the flange at the upper part of the strainer is clamped on the clamping blocks in different positions, the size of the gap between the conical body and the transfusion tube changes so as to regulate transfusion flow rate; and the drip cup is extruded by two hands, so that the inner diameter of the drip cup is increased in the direction of the clamping blocks, the flange at the upper part of the strainer disengages from the clamping blocks and can be moved, the drip cup restores into a round through the elasticity of the drip cup after the two hands loosen, and the flange is clamped on another clamping block.
Description
Technical field
This utility model medical apparatus and instruments relates in particular to the speed regulator of regulating flow velocity in the intravenous transfusion device.
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, 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, the speed governing of transfusion device herb liquid is by speed regulator tube for transfusion to be squeezed into flat its middle through hole reduced cross-sectional that makes to regulate, medical personnel need to observe in adjustment process drips in the kettle speed of dripping of drop and estimates the medicinal liquid flow velocity, degree of accuracy is poor, and needs to consume the long period.
Summary of the invention
The purpose of this utility model provides a kind of venous transfusion arrangements for speed regulation that make things convenient for the regulating flow velocity.
Venous transfusion arrangements for speed regulation of the present utility model are in dripping kettle bullet to be arranged, the all or part of tube for transfusion that drips the kettle bottom that is inserted into of this bullet, the connection flat cylindrical screen is arranged at bullet top, curved flanges is arranged at screen cloth top, the screens piece of some radial symmetric is arranged in order to stick the curved flanges on screen cloth top on the medial wall of a kettle.
The correspondence position of above-mentioned kettle outside screens piece can have the flow velocity scale.
This utility model is stuck on the screens piece by the flange on screen cloth top, the bullet partial insertion is at the tube for transfusion that drips the kettle bottom, medicinal liquid flows down from the gap between bullet and the tube for transfusion, when the flange on screen cloth top is stuck in the screens piece of diverse location, gap length between bullet and the tube for transfusion changes, thereby regulating transfusion flow velocity, kettle is dripped in the both hands extruding makes a kettle add large diameter in screens piece direction, the flange on screen cloth top breaks away from the screens piece, can mobile flange, circular by the elastic return of dripping kettle after both hands unclamp, flange is stuck in another screens piece.

Fig. 1 is a kind of embodiment cutaway view of this utility model.
Fig. 2 is that Fig. 1 drips kettle A-A cutaway view under squeezed state.
The specific embodiment
This utility model is the improvement to intravenous transfusion device commonly used, this 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, 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.
Venous transfusion arrangements for speed regulation of the present utility model are in above-mentioned kettle 1 bullet 2 to be arranged, bullet 2 upper diameter are larger, lower diameter is less, bullet 2 is all or part of be inserted into the tube for transfusion 6 that drips the kettle bottom after, medicinal liquid is by the Clearance Flow between bullet 2 and the tube for transfusion 6, when bullet 2 is positioned at a high position, gap between bullet 2 and the tube for transfusion 6 is larger, and the medicinal liquid flow velocity is larger, otherwise, when bullet 2 is positioned at low level, gap between bullet 2 and the tube for transfusion 6 is less, and the medicinal liquid flow velocity is less, this shows, by the position of cone governor body 2, just can the regulating flow velocity.
The top connection flat cylindrical screen 3 of bullet 2, curved flanges 4 is arranged at screen cloth 3 tops, and the screens piece 5 of some radial symmetric is arranged on the medial wall of a kettle 1, and curved flanges 4 is stuck in the screens piece 5.Screen cloth 3 can make medicinal liquid not pass through arrangements for speed regulation with being stopped.By regulating the height that screens piece 5 that curved flanges 4 is stuck in diverse location can cone governor body 2 positions.When bullet 2 positions are turned down, the top of curved flanges 4 on the kettle 1 is dripped in two finger extruding, make a kettle 1 add large diameter at screens piece direction place, curved flanges 4 just breaks away from screens piece 5, curved flanges 4 can move down, circular by the elastic return of dripping kettle after both hands unclamp, curved flanges 4 is stuck in next screens piece 5; When bullet 2 positions are heightened, the bottom of curved flanges 4 on the kettle 1 is dripped in two finger extruding, make a kettle 1 add large diameter at screens piece direction place, curved flanges 4 just breaks away from screens piece 5, curved flanges 4 can move up, if curved flanges 4 moves up is obstructed, and can drip kettle generation thrust upwards in a kettle bottom extruding curved flanges 4 is moved up smoothly, circular by the elastic return of dripping kettle after both hands unclamp, curved flanges 4 is stuck in a screens piece 5.
Because after curved flanges 4 is stuck in each screens piece 5, bullet 2 and the gap of dripping between the tube for transfusion of kettle bottom are determined, the flow velocity of medicinal liquid when can obtain curved flanges 4 and be stuck in each screens piece 5 by measuring, the corresponding position that measured value is labeled in the outside screens piece 5 that drips kettle 1 becomes the flow velocity scale, can allow medical personnel's quick adjustment to suitable transfusion speed.
Claims (2)
1. venous transfusion arrangements for speed regulation, it is characterized in that, drip in the kettle bullet is arranged, the all or part of tube for transfusion that drips the kettle bottom that is inserted into of this bullet, bullet top connection flat cylindrical screen, curved flanges is arranged at screen cloth top, the screens piece of some radial symmetric is arranged in order to stick the curved flanges on screen cloth top on the medial wall of a kettle.
