Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to an infusion connector. Background Art

[0002] It is known that patients are often given infusion therapy during hospital treatment. The infusion connectors used in the infusion process play an important role in the infusion, not only affecting the patient's infusion safety, but also directly affecting the quality of medical care. When using the infusion connector, it is necessary to ensure that the connection is tight to avoid air residue and liquid reflux. In order to reduce the risk of infection, the infusion connector must be replaced or disinfected in a timely manner. Among them, the infusion tube connectors are mostly threaded Luer connectors.

[0003] However, in actual use, when performing multi-channel drug delivery, multiple infusion tubes are often connected to a multi-way connector, and the existing multi-way connector has some difficult-to-overcome problems:

[0004] 1. The conduction direction of the multi-way connector needs to be controlled by a control valve;

[0005] 2. After the infusion bottle has finished infusing the medicine, if it is not discovered and closed in time or a new infusion bottle is not added, medical accidents such as blood backflow may occur. If the infusion bottle is checked frequently, the workload of medical staff will increase.

[0006] Therefore, an infusion connector is proposed as a further improvement. Utility Model Content

[0007] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present utility model provides an infusion connector to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an infusion connector, comprising: an infusion tube body, a butt joint tube and an anti-dropping member;

[0009] The butt joint is fixedly mounted on the inner wall of the infusion tube body, and a one-way duckbill valve is fixedly mounted on the butt joint inside the infusion tube body;

[0010] The anti-falling part includes: a connecting piece, a push piece, a paddle piece and a power-assisting piece;

[0011] One end of the connecting piece is fixedly connected to the paddle, and the other end of the connecting piece is fixedly connected to the push piece and the power-assisting piece. A U-shaped frame is fixedly installed at the end of the infusion tube near the butt joint, and both sides of the connecting piece are rotatably connected to the two inner sides of the U-shaped frame through a rotating shaft;

[0012] The push piece and the paddle are both provided with a tube opening groove for clamping with the infusion tube connector.

[0013] Furthermore, the rotation angle of the connecting piece with the rotation axis as the center is set to 0-30°.

[0014] Furthermore, the push piece and the paddle are both configured to be U-shaped.

[0015] Furthermore, the angle between the power-assisting plate and the connecting plate is set to 90-180°.

[0016] Furthermore, the angle between the connecting piece and the paddle is set at 100-110°.

[0017] Furthermore, the material of the connecting piece is set to be elastic silicone material.

[0018] The technical effects and advantages of this utility model are:

[0019] Compared with the prior art, by setting up a docking tube, since the docking tube is fixedly installed with a one-way duckbill valve, the one-way duckbill valve can prevent the infusion tube body from backflowing, that is, after the infusion bottle has infused the medicine, the infusion tube body uses the anti-return effect of the one-way duckbill valve, which not only always keeps the pressure inside the infusion tube body higher than the pressure of the external environment, but also prevents the medicine inside the infusion tube body from entering the docking tube, thereby achieving a one-way sealing effect. After the infusion bottle has infused the medicine, there is no need to check the infusion bottle frequently, which will reduce the workload of medical staff; and there is no need to control the conduction direction through a control valve, thereby improving practicality; by setting up an anti-falling part, the infusion tube connector connected to the infusion bottle is prevented from falling off due to external force after docking with the docking tube; according to the infusion tube connector connected to the infusion bottle adopts a Luer connector, the tube mouth groove opened by the push piece and the pick piece is clamped with the infusion tube connector, thereby preventing the infusion tube from being subjected to external force and causing the infusion tube connector to fall off after docking with the docking tube.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] As attached Figure 1 , Attachment Figure 2 and attached Figure 3 The infusion connector shown includes: an infusion tube body 1, a butt joint tube 2 and an anti-dropping member 3;

[0033] The butt joint pipe 2 is fixedly mounted on the inner wall of the infusion tube body 1, and a one-way duckbill valve is fixedly mounted on the butt joint pipe 2 located inside the infusion tube body 1;

[0034] Among them, the one-way duckbill valve is used to prevent backflow in the infusion tube body 1. That is, after the infusion bottle has finished infusing the liquid medicine, the infusion tube body 1 uses the one-way duckbill valve to prevent backflow, not only always keeping the pressure inside the infusion tube body 1 higher than the pressure of the external environment, but also preventing the liquid medicine inside the infusion tube body 1 from entering the docking tube 2, achieving a one-way sealing effect;

[0035] Among them, when the infusion tube connector 7 connected to the infusion bottle is docked with the docking tube 2, only the external medicine will enter the one-way duckbill valve along the docking tube 2; there is no need to control the conduction direction through the control valve;

[0036] The anti-falling member 3 includes: a connecting piece 31, a push piece 32, a paddle 33 and a power-assisting piece 34;

[0037] One end of the connecting piece 31 is fixedly connected to the paddle 33, and the other end of the connecting piece 31 is fixedly connected to the push piece 32 and the assist piece 34. A U-shaped frame 4 is fixedly installed on the end of the infusion tube body 1 near the docking tube 2. The two sides of the connecting piece 31 are rotatably connected to the two inner sides of the U-shaped frame 4 through the rotating shaft 5.

[0038] The push piece 32 and the paddle 33 are both provided with a tube opening groove 6 for engaging with the infusion tube connector 7 .

[0039] The anti-dropout member 3 is used to prevent the infusion tube connector 7 connected to the infusion bottle from being dropped off due to external force after being docked with the docking tube 2. Therefore, since the infusion tube connector 7 connected to the infusion bottle adopts a Luer connector, the tube opening groove 6 formed by the push piece 32 and the paddle 33 is engaged with the infusion tube connector 7 to prevent the infusion tube from being dropped off due to external force after being docked with the docking tube 2.

[0040] When the anti-dropping member 3 is in the closed state, the upper surface of the connecting piece 31 is flush with the upper surface of the infusion tube body 1 so that the whole is flat and easy to disinfect;

[0041] In a preferred embodiment, as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the rotation angle of the connecting piece 31 with the rotating shaft 5 as the center is set to 0-30 degrees, so that the connecting piece 31 rotates to drive the push piece 32 and the paddle 33 to control the clamped infusion tube connector 7:

[0042] Among them, when the surface of the connecting piece 31 is parallel to the infusion direction of the docking tube 2, the push piece 32 and the paddle 33 can maintain the connection between the infusion tube connector 7 and the docking tube 2; and when the surface of the connecting piece 31 deviates from the parallelism with the infusion direction of the docking tube 2, the increased deviation angle will cause the push piece 32 and the paddle 33 to disconnect the infusion tube connector 7 from the docking tube 2, thereby facilitating the removal of the infusion tube connector 7.

[0043] In a preferred embodiment, as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the push piece 32 and the paddle 33 are both U-shaped so that the push piece 32 and the paddle 33 can clamp the infusion tube connector 7 to prevent it from falling off.

[0044] In a preferred embodiment, as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the angle between the assisting piece 34 and the connecting piece 31 is set to 90-180 degrees, so that the operator can use the assisting piece 34 to control the connecting piece 31 to rotate around the rotating shaft 5 as the center.

[0045] In a preferred embodiment, as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the angle between the connecting piece 31 and the paddle 33 is set at 100-110°;

[0046] When the operator manipulates the infusion tube connector 7 to connect with the docking tube 2, the axial direction of the end of the infusion tube connector 7 is perpendicular to the paddle 33, and the infusion tube connector 7 passes through the tube opening groove 6 of the paddle 33 and connects with the docking tube 2 without being hindered by the paddle 33. The connecting piece 31 then rotates to clamp the tube opening groove 6 of the push piece 32 to the infusion tube connector 7, preventing it from falling off. At this time, the paddle 33 rotates with the connecting piece 31 in a direction away from the infusion tube connector 7.

[0047] If the operator needs to disconnect the infusion tube connector 7 from the docking tube 2, the operator rotates the connecting piece 31 to move the paddle 33 toward the infusion tube connector 7, and then the infusion tube connector 7 can be pulled out. At this time, the tube opening groove 6 of the push piece 32 that rotates with the connecting piece 31 will also be disengaged from the infusion tube connector 7.

[0048] In a preferred embodiment, as shown in the attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the material of the connecting piece 31 is set to be elastic silicone material, so as to ensure that the infusion tube connector 7 is connected or disconnected with the docking tube 2.

[0049] Working principle of this utility model:

[0050] When in use, if the infusion tube connector 7 is connected to the butt joint 2, the user lifts the connecting piece 31 and the push piece 32 by lifting the assisting piece 34, so that the axial direction of the end of the infusion tube connector 7 is perpendicular to the paddle piece 33, and the infusion tube connector 7 passes through the tube opening groove 6 of the paddle piece 33 and is connected to the butt joint 2; then, the assisting piece 34 is pressed down to rotate the connecting piece 31 and the tube opening groove 6 of the push piece 32 is engaged with the infusion tube connector 7 to prevent it from falling off; at this time, the paddle piece 33, which rotates with the connecting piece 31, rotates away from the infusion tube connector 7 to avoid mutual interference;

[0051] If it is necessary to disconnect the infusion tube connector 7 from the docking tube 2, the user lifts the connecting piece 31 and moves the paddle 33 toward the infusion tube connector 7 to remove the infusion tube connector 7. At this time, the push piece 32 lifted by the connecting piece 31 will also disengage the tube opening groove 6 from the infusion tube connector 7.
