Description

Connector Integral Clamp Assembly {CONNECTER INTEGRATED TYPE CLAMP ASSEMBLY}

The present invention relates to a clamp assembly, and more particularly, to a connector-integrated clamp assembly for controlling the flow of gas or liquid moving through a tube.

In general, in the case of patients who cannot eat food, surgery patients, and patients who need to supply nutrients due to deterioration of the human body, the fluid is administered into the blood vessel of the patient through a medical fluid set. In addition, in the case of patients in need of blood transfusion, the blood transfusion is performed into the blood vessel of the patient through a blood transfusion set.

For example, when administering infusion or blood transfusion to the human body, a catheter is mounted on the patient's vein or tissue, and then, with the cannula and cannula hub removed, the connector connected to the distal end of the infusion tube is connected to the rear end of the catheter. will be used

At this time, depending on whether the IV tube and the catheter are connected and the condition of the patient, it is necessary to open and close the flow path of the IV tube or adjust the flow rate of the IV fluid. For this, a clamp for adjusting the flow rate of the IV fluid is provided on the IV tube.

There are various clamp units such as roller clamp method, dosi-flow method, and pinch clamp method as clamps that control the flow rate of infusion fluid passing through the infusion tube. At the distal end of the infusion tube connected to the catheter or syringe, a clamp unit of a pinch clamp type for opening and closing the infusion toward the catheter or syringe is basically mounted.

In the existing pinch clamp, through holes are formed in the front and rear so that the IV tube is inserted therethrough, and the fixed plate and the moving plate disposed with the IV tube in between are closed or spread by the user's pinch force by pressing the IV tube placed in between. It opens or closes or controls the flow rate of the infusion fluid passing through the infusion tube.

However, since the existing pinch clamp simply maintains a state of being hung over the IV tube, it cannot be fixed at a fixed position in the open state of the passage of the IV tube and can be easily moved along the IV tube.

In general, a connector (connection tip) for connecting an external device such as a catheter or syringe is provided at the distal end of the IV tube. If the pinch clamp moves away from the connector as the position on the IV tube is moved, an external device is installed Difficulty arises in the process.

For example, when a user holds a connector with one hand and wants to attach an external device to the connector with the other hand, it is necessary to open and close the flow path of the IV tube by manipulating a pinch clamp. Many difficulties arise in manipulating the pinch clamp while holding the connector.

In describing the present embodiments, the same names and reference numerals may be used for the same components, and an additional description thereof may be omitted.

The connector-integrated clamp assembly according to an embodiment of the present invention includes a clamp unit 100 and a connector unit 200 .

In the following description, for convenience, the infusion tube (T) is divided into before (front) and after (after) based on the direction in which the infusion fluid flows. For example, the direction from the clamp unit 100 toward the connector unit 200 is the front, and the direction from the connector unit 200 to the clamp unit 100 is the rear.

The clamp body 110 is inserted through the infusion tube (T), and the flow rate of the infusion can be adjusted according to the user's external force pressing the infusion tube (T) to change the channel cross-sectional area of the infusion tube (T). .

For this purpose, the clamp body 110 may include a fixed part 111 , a rear extension part 112 , a front connection part 113 , and a moving part 114 .

The fixing part 111 may be formed to extend in parallel with the IV tube (T), and a first pressing part (111a) in close contact with the IV tube (T) may be formed to protrude from one surface facing the IV tube (T). .

The rear extension part 112 may be formed to extend upward to cross the IV tube (T) at the rear end of the fixed part, and in this case, the rear extension part 112 has a rear through hole (110a) through which the IV tube (T) passes. ) can be formed. When viewed from the rear, the rear through hole (110a) may be a long hole elongated in the direction (up and down direction in the drawing) crossing the infusion tube (T), and accordingly, the rear extension part 112 is the infusion tube (T). It may be formed in a long annular shape in an intersecting direction. As such, in the rear extension portion 112 formed in a substantially annular shape, elastic restoring force may be generated in the front and rear directions with respect to the fixing portion 111 .

In addition, a locking jaw 112a protruding forward may be provided at an end of the rear extension portion 112 , and a locking jaw 112b may be formed to protrude rearward to the opposite side of the locking jaw 112a. .

When an external force is applied to the portion 112b, the rear extension portion 112 is elastically deformed and the locking jaw 112a may be separated from the locking hook 114b.

The front connection part 113 may be formed to extend upward to face the rear extension part 112 from the front end of the fixing part 111, and in this case, the front connection part 113 has a front through hole through which the IV tube (T) passes. 110b may be formed. When viewed from the front, the front through hole 110b may be a long hole elongated in the direction (up and down direction in the drawing) intersecting the infusion tube T, and accordingly, the front connection part 113 crosses the infusion tube T. It may be formed in an approximately annular shape elongated in the direction of As such, the rear extension portion 112 formed in the annular shape may generate an elastic restoring force in the front and rear directions around the fixing portion 111 .

The moving part 114 may be formed extending rearwardly to face the fixed part 111 from the end of the front connecting part 113, and one surface facing the first pressing part 111a with the infusion tube T interposed therebetween. The second pressing portion 114a in close contact with the infusion tube (T) may be formed to protrude.

In addition, a locking hook 114b coupled to the locking jaw 112a may be formed at an end of the moving part 114 . At this time, the flow path of the infusion tube (T) can be maintained in a completely closed state in the state in which the locking jaw (112a) and the locking hook (114b) are coupled.

In addition, a gripping protrusion 114c may be formed on the upper surface of the moving part 114 so that an accurate pressing force can be applied without slipping when an external force is applied from the user.

The contact portion 235 may be in close contact with the front surface of the front connection part 113 while the first locking part 132 and the second locking part 233 are caught and supported. Accordingly, the clamp unit 100 and the connector The coupling position of the unit 200 can be made more firmly.

And, since the front connection part 113 and the close contact part 235 are kept in close contact, if it is necessary to separate the clamp body 110 from the connector unit 200, the rear extension part 112 When the locking hook (114b) part of the moving part 114 separated from the front side is pressed upward, a reaction force is generated rearwardly in the front connection part 113 in close contact with the close contact part 235, like the principle of a lever, As the first locking part 132 is separated from the second locking part 233 by this reaction force, the coupling protrusion 131 may be easily separated from the coupling groove part 232 .

The coupling groove 232 is arranged in a pair on both sides of the body 231, and each coupling groove 232 is concave in a shape corresponding to the shape of the coupling protrusion 131 so that the coupling protrusion 131 is inserted. can be
