Description

[0001] The present invention relates to an adjustable travel path for a liquid injector,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable conduit variable connector, and more particularly, to a movable conduit variable connector capable of varying a path through which a chemical liquid moves according to a type of a chemical liquid, To a moving path variable connector for an injection device.

Patients admitted to a hospital or illnesses with reduced digestive function are often given nutritional supplements, such as sap, or drugs such as glucose. In this case, the liquid is injected into the patient through a chemical liquid adjusting device which can be easily seen at a place such as a hospital. The liquid medicament adjusting device connects the end of the hose connected to the linger bottle or the pack and the injection needle inserted into the blood vessel of the patient, The amount of the drug solution contained in the bottle or pack is administered to the blood vessel of the patient.

Currently, a ringer device commonly used in medical institutions is classified into two types: a method in which a pack or a bottle containing a liquid is lifted higher than a scanning position by gravity and the potential energy is secured and the pressure difference is used for scanning.

One method is to install the hose connected to the injection needle so as to be accommodated inside the chemical liquid control device and to move the pressure roller moving in the inclined groove to press the hose to change the flow cross section of the hose to reduce or enlarge the cross- And the other method is a method of controlling the flow rate of the chemical liquid by using the flow resistance of the fluid by constructing the micro flow path in the flow control valve of the chemical liquid control device.

On the other hand, a three-way valve is used in order to inject a different chemical solution in addition to the solution administration, or to collect a chemical solution flowing through the passage.

This three-way valve is constituted by a main body portion having a branch pipe capable of moving a chemical solution in three branch openings and a flow path switching portion. And a combination of branch pipes through which the chemical liquid in communication with the branch pipe into which the chemical liquid is introduced by the rotation operation of the handle integrally formed with the channel switching portion can be selected.

Among the three branch pipes in the conventional three-phase valve, the first branch pipe and the second branch pipe are arranged so as to form a straight line flow path when they communicate with each other, and this flow path serves as a main line.

Further, the branch pipe arranged so as to be vertically positioned on the main line is used as the third branch pipe, and the chemical liquid is mixedly injected or collected in the third branch pipe. The communicating flow path is mainly formed in a T shape.

Korean Patent No. 10-0731429 discloses that among the branch openings, the first branch opening and the second branch opening are formed in a straight line, and the third branch opening is perpendicular to the straight line connecting the first branch opening and the second branch opening A third flow path is formed in a direction orthogonal to a straight line connecting the first flow path and the second flow path and the first flow path and the second flow path formed in a line on the flow path switching portion, There is described a description of a three-way valve in which two fluid paths connecting a flow path, a third flow path, a third flow path and a second flow path are formed, and two flow paths are communicable in the vicinity of the third flow path .

Japanese Unexamined Patent Application Publication No. 11-342209 discloses that a partition made of an elastic body having a slit capable of puncturing the blunt needle is provided at a position corresponding to the third branch, A description of a technique for a three-way valve for eliminating negative pressure is described.

In Korean Patent Laid-Open Publication No. 10-2003-0060424, the one end is connected to a three-way valve commonly used for other connectors or medical use, and the other end is connected to insert the front end of the syringe so that the front end of the syringe is inserted, It can be seen that the constructed medical connector is open

Conventionally, however, when a drug solution injector or a syringe injects a drug into a drug solution, the drug solution injected into the ampule or vial used as an injection solution enters the body and flows along the bloodstream From the lungs sequentially through the liver, spleen and many other organs to reach the kidney. When such glass fragments occlude blood vessels, they block blood supply and are exposed to risks of chronic tissue necrosis, vascular granuloma, embolization, and the like.

Accordingly, a technique has been actively developed to provide a filter in a drug solution regulating device or a syringe to inject an injecting solution through a built-in filter, thereby effectively suppressing the foreign substance to be injected into the human body together with the injecting solution.

However, the chemical liquid is classified into a chemical liquid containing a pure liquid and a chemical liquid containing a powder chemical. Accordingly, when a chemical solution containing a powdered medicament is injected into a human body using a medicinal solution regulating device or a syringe containing a filter, there is a problem that the filter filters the medicines required for healing.

Further, since the use thereof has to be limitedly limited, there has been a problem that inconvenience is caused in the use process.
