Abstract
An infusion apparatus flow velocity control valve consists of an upper pipe joint, a valve body, a valve core, a control handle, a lower pipe joint and a helical locking joint. The valve body is a main body piece of the utility model and is in a hollow round shape. The rotatable valve core is arranged in the valve body. The outer edge of the valve core is provided with a control handle which can control the rotation of the valve core. 2 to 6 through holes are arranged in the valve core and the 2 to 6 through holes with different inner diameters are formed. The utility model is provided with 7 control gears. The seventh control gear is not communicated, i.e. a close gear on the control valve. The upper end of the valve body is provided with the internally communicated upper pipe joint and the lower end thereof is provided with the internally communicated lower pipe joint which is provided with the helical locking joint connected through an internal wire. The utility model has the advantages of simple whole structure, convenient operation and use, good stability and high reliability.
Description
Technical field:
This utility model relates to medical apparatus and instruments, relates in particular to a kind of transfusion device flow control valve.
Background technology:
The size of transfusion device medicinal liquid flow depends on the speed of dripping of Murphy's burette place medicinal liquid, i.e. the unit interval inner liquid medicine quantity of dripping.The flow controller of prior art adopts the roller type structure, with the flow velocity of the extent control medicinal liquid that compresses conduit, when specifically regulating, on one side to see stopwatch, on one side number drip several.The transfusion device of this structure is feasible for general transfusion, but is infeasible for accurate transfusion.Because from the actual volume of effusive each drops physic liquor of dropper, can be subjected to the influence of the factor such as temperature, density, viscosity, flow velocity of medicinal liquid, environment and himself condition different all can cause the actual volume of each drops physic liquor also inequality.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of transfusion device flow control valve is provided, and the control flow velocity is realized relative accurate measurement.
Transfusion device flow control valve described in the utility model includes upper conduit joint, valve body, spool, joystick, downcomer joint and spiral lock-on connection and forms.Said valve body is a main component of the present utility model, and whole hollow circle is provided with rotary spool in the valve body.Said spool, outer are provided with the joystick that is used to control valve core rotation, are provided with 2 to 6 through holes in the spool, form 2 to 6 through holes that the internal diameter size has nothing in common with each other.With 6 through holes is example, first through hole wherein is that per minute drips 15 through hole, second through hole is that per minute drips 30 through hole, the 3rd through hole is that per minute drips 45 through hole, the 4th through hole is that per minute drips 90 through hole, and the 5th through hole is that per minute drips 120 through hole, and the 6th through hole is the through hole of limited flow rate not, that is to say that the internal diameter of the 6th through hole is identical with the internal diameter of transfusion catheter.This utility model is provided with 7 control gears, and said the 7th control bit is not conducting position, the close stance that just is provided with on control valve.In the upper end of said valve body, the upper conduit joint that leads in being provided with, in the lower end of said valve body, the downcomer joint that leads in being provided with.On said downcomer joint, be provided with the spiral lock-on connection that internal thread connects.
Transfusion device flow control valve described in the utility model, overall structure is simple, and is easy for operation, good stability, reliability height.
Description of drawings:
The specific embodiment:
Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: transfusion device flow control valve described in the utility model includes upper conduit joint 1, valve body 2, spool 3, joystick 4, downcomer joint 5 and spiral lock-on connection 6 and forms.Said valve body 2 is main components of the present utility model, and whole hollow circle is provided with rotary spool 3 in the valve body 2.Said spool 3, outer are provided with and are used to control the joystick 4 that spool 3 rotates, and are provided with 2 to 6 through holes in the spool 3, are formed with 2 to 6 through holes that the internal diameter size has nothing in common with each other.With 6 through holes is example, first through hole wherein is that per minute drips 15 through hole, second through hole is that per minute drips 30 through hole, the 3rd through hole is that per minute drips 45 through hole, the 4th through hole is that per minute drips 90 through hole, and the 5th through hole is that per minute drips 120 through hole, and the 6th through hole is the through hole of limited flow rate not, that is to say that the internal diameter of the 6th through hole is identical with the internal diameter of transfusion catheter.This utility model is provided with 7 control gears, and said the 7th control bit is not conducting position, the close stance that just is provided with on control valve.In the upper end of said valve body 2, the upper conduit joint 1 that leads in being provided with, in the lower end of said valve body 2, the downcomer joint 5 that leads in being provided with.On said downcomer joint 5, be provided with the spiral lock-on connection 6 that internal thread connects.Transfusion device flow control valve described in the utility model, overall structure is simple, and is easy for operation, good stability, reliability height.
