Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Please refer to fig. 1 to fig. 3. According to an embodiment of the present invention, an infusion tube clamp includes a first arm 1, a second arm 2, a connecting portion 3 connecting one end of the first arm 1 and one end of the second arm 2, a latch arm 4 bent from the other end of the first arm 1 toward the second arm 2, a first pressing portion 5, and a second pressing portion 6.

The first pressing portion 5 and the second pressing portion 6 are fixed to the inner surface of the first arm portion 1 and the inner surface of the second arm portion 2, respectively. The first arm 1 and the second arm 2 are expandable in a direction away from each other by an elastic force provided by the connecting portion 3, and in this embodiment, the connecting portion 3 has a U-shape.

The top of the latch arm 4 is provided with a first locking portion 41 and a second locking portion 42, and the second locking portion 42 is located below the first locking portion 41. The other end of the second arm 2 is provided with a locking hole 20 for the locking arm to pass through, a first buckling part 21 matched with the first buckling part 41, and a second buckling part 22 matched with the second buckling part 42.

In the present embodiment, the first locking portion 41 is located at the tip of the latch arm portion 4. The first engaging portion 41 includes a pair of protruding portions 411 protruding outward from opposite sides of the latch arm portion 4, respectively, and the first engaging portion 21 includes a pair of protrusions 211 protruding inward of the card hole 20 from opposite sides thereof. Alternatively, the opposite surfaces of the pair of protrusions 211 have guiding inclined surfaces 213, and the guiding inclined surfaces 213 are used for guiding the pair of protrusions 411 to be engaged with the pair of protrusions 211. The gap between the guide slopes 213 of the pair of projections 211 gradually narrows from wide (in the example of fig. 1, from below to above) in the direction in which the pair of projections 213 enter the card hole 20.

In the present embodiment, the second fastening portion 42 is a hook portion disposed outside the latch arm, and the edge of the card hole 20 near the other end (free end) of the second arm portion constitutes the second engaging portion 22. The hook portion 42 has a guiding inclined surface 421 and a fastening surface 422, the guiding inclined surface 421 is used for guiding the hook portion 42 to enter the fastening hole 20, and the fastening surface 421 is used for fastening the second fastening portion 22.

The second arm 2 is movable relative to the latch arm 4 from a first latching position to a second latching position. When the second arm 2 is moved downward by an external force, the pair of guiding slopes 213 abut against the pair of protrusions 411 and slide downward, and when the pair of protrusions 411 reach above the pair of guiding slopes 213, the pair of guiding slopes 213 are slightly spread outward, so that the pair of protrusions 411 can pass over the pair of guiding slopes 213 and snap onto the top surfaces of the pair of protrusions 211, respectively, and the second arm 2 is in the first locking position, as shown in fig. 4. When the second arm 2 is at the first lock position, the first pressing portion 5 and the second pressing portion 6 abut against the infusion tube 9, the flow path of the infusion tube 9 is opened, and the conduction state is maintained, as shown in fig. 6.

When the second arm portion 2 continues to move downward under the external force, the engaging hole 20 abuts against the guiding inclined surface 421 of the engaging portion, the second arm portion 2 slides downward along the guiding inclined surface 421 and drives the locking arm portion 4 to elastically deform inward, and when the engaging surface 422 of the engaging portion 42 engages with the edge 22 of the engaging hole 20 close to the other end of the second arm portion, the second arm portion 2 is in the second locking position, as shown in fig. 5. When the second arm 2 is at the second lock position, the first pressing portion 5 and the second pressing portion 6 press the infusion tube 9, and the flow path of the infusion tube 9 is closed.

When unlocking is required, only a force of deforming inward is applied to the latch arm portion 4, and the second arm portion 2 is opened away from the first arm portion 1 by the elastic force of the connecting portion 3, thereby releasing the latch with the first arm portion 1.

In the present embodiment, the first pressing portion 5 and the second pressing portion 6 both define a closed space 7 for accommodating the infusion tube 9 when the second arm portion 2 is in the first locking position and the second locking position, so that the infusion tube 9 can be prevented from being displaced under the action of external force, and the safety of infusion can be improved. When the infusion tube 9 is displaced during infusion, the safety of the infusion may be affected.

In this embodiment, the first pressing part 5 includes a first pressing part body 50, and both sides of the first pressing part body 50 are respectively provided with a first boss 51 and a first boss groove 52; the second pressing part 6 includes a second pressing part body 60, and both sides of the second pressing part body 60 are respectively provided with a second boss groove 61 matched with the first boss 51 and a second boss 62 matched with the first boss groove 52.

When the second arm 2 is in the first locking position, the first pressing body 50 and the second pressing body 60 abut against the infusion tube 9, and the first boss 51 and the second boss 62 respectively partially extend into the second boss groove 61 and the first boss groove 52, so that the infusion tube 9 is fixed but is not clamped until the flow path is closed; when the second arm 2 is in the second locking position, the infusion tube 9 is pressed by the first pressing part body 50 and the second pressing part body 60, the first boss 51 and the second boss 62 respectively and completely extend into the second boss groove 61 and the first boss groove 52, at this time, the first pressing part 5 and the second pressing part 6 are completely clamped, and the infusion tube 9 is clamped to the flow path to be closed. The first and second

squeeze part bodies

50, 60, the first and

second bosses

51, 62 together define the aforementioned enclosed space 7.

Optionally, the infusion tube clamp of the present embodiment is integrally formed by injection molding. The infusion tube clamp has the advantages of simple structure and small volume, and can save the occupied space when being used for an infusion pump.

The present embodiments have been described in conjunction with specific examples, but it will be understood by those of ordinary skill in the art that the present invention is not limited to the examples described herein, and that various modifications and changes may be made without departing from the spirit and scope of the present invention.
