Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a medical four-way infusion connector. Background Technology

[0002] In modern medical practice, administering multiple medications to patients simultaneously is a common and crucial procedure for the treatment and rescue of complex diseases. In the intensive care unit, the treatment of critically ill patients often requires the simultaneous implementation of multiple measures, such as anti-infection, maintaining electrolyte balance, supplementing nutrients, and administering emergency drug injections. This necessitates the administration of different types of medications to patients within the same timeframe.

[0003] A search revealed that publication number CN220125232U describes an infusion four-way connector, comprising an outer shell, an inner shell, a central chamber, and an inlet pipe, an outlet pipe, a first side pipe, and a second side pipe arranged in a cross shape. An annular channel is provided between the outer shell and the inner shell. A rotatable adjusting ring is located above the inlet in the annular channel, and two adjacent 90-degree stop valves are located below the adjusting ring. The stop valves can completely cover the inlet. When any two adjacent inlets are blocked by the stop valves, the other two inlets can still communicate through the central chamber. When the stop valve is located between two inlets, all four inlets can communicate through the central chamber. This utility model provides an infusion four-way connector that, compared to a three-way connector, adds a medication side port, saving resources. Simultaneously, through the built-in adjusting ring and the adjacent 90-degree stop valves, it can achieve the same "two-way" and "full-way" functions as a three-way connector.

[0004] While the aforementioned device can achieve multi-channel infusion in actual use, it lacks effective anti-backflow measures. When the infusion pressure of different channels is uneven, backflow of medication is likely to occur. This may not only lead to an uncontrolled mixing ratio of different medications, affecting the treatment effect, but may also cause cross-contamination and increase the risk of infection for patients.

[0006] This utility model is a medical four-way infusion connector, comprising:

[0007] An interface component, comprising a docking seat, a tube body, and a handle, wherein the tube body is fixed to both sides of the outer surface of the docking seat, and the handle is mounted on the upper surface of the docking seat;

[0008] The anti-backflow component includes a positioning ring, a support block, a damping rod, a support ring, and a damping ring. The positioning ring is fixed at both ends of the outer surface of the tube body, the support block is fixed at the top and bottom of the positioning ring, the damping rod is disposed between the two support blocks, the damping ring is dampingly connected to the outer surface of the damping rod, and the positioning ring is located on the outer surface of the damping ring and clamped to the outer surface of the handle.

[0009] Furthermore, the anti-backflow component also includes a support frame, which is fixed between the damping ring and the positioning ring.

[0010] Furthermore, a rubber inner ring is bonded to the inner surface of the positioning ring, and limit rings are fixed to the top and bottom of the rubber inner ring.

[0011] Furthermore, the inner rubber ring surrounds the outer surface of the handle, and the limiting ring fits against the top and bottom of the handle.

[0012] Furthermore, the interface component also includes a control base and an interface. The control base is disposed on the inner surface of the docking seat, the handle is fixed to the top of the control base, and the interface is fixed to one end of the outer surface of the docking seat.

[0013] Furthermore, it also includes installation components, which include a connecting pipe, a retaining ring, an extension ring, a rubber post, a snap-fit ​​groove, and a snap-fit ​​block. The connecting pipe is embedded at one end of the outer surface of the interface, the retaining ring is fixed to the outer surface of the interface, the extension ring is disposed on the outer surface of the retaining ring and surrounds the outer surface of the connecting pipe, the snap-fit ​​groove is opened at one end of the outer surface of the extension ring, the snap-fit ​​block is fixed to the outer surface of the connecting pipe and inserted into the inside of the snap-fit ​​groove, and the rubber post is adhered to the inner wall of the snap-fit ​​groove.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-3 As shown, this utility model is a medical four-way infusion connector, comprising:

[0029] The interface 104 component includes a docking seat 100, a tube body 101, and a handle 103. The tube body 101 is fixed to both sides of the outer surface of the docking seat 100, and the handle 103 is installed on the upper surface of the docking seat 100.

[0030] The anti-backflow component includes a positioning ring 200, a support block 201, a damping rod 202, a support ring 203, and a damping ring 204. The positioning ring 200 is fixed at both ends of the outer surface of the tube body 101, the support block 201 is fixed at the top and bottom of the positioning ring 200, the damping rod 202 is disposed between the two support blocks 201, the damping ring 204 is dampingly connected to the outer surface of the damping rod 202, and the positioning ring 200 is located on the outer surface of the damping ring 204 and clamped on the outer surface of the handle 103.

[0031] By moving the damping ring 204 outside the damping rod 202, the positioning ring 200 can be pushed, so that the positioning ring 200 is clamped outside the handle 103, thereby fixing the angle of the handle 103 after rotation.

[0032] The anti-backflow component also includes a support frame 205, which is fixed between the damping ring 204 and the positioning ring 200;

[0033] The damping ring 204 and the positioning ring 200 are supported by the support frame 205.

[0034] A rubber inner ring 207 is bonded to the inner surface of the positioning ring 200, and a limit ring 206 is fixed to the top and bottom of the rubber inner ring 207.

[0035] The inner rubber ring 207 is made of a relatively soft material, which can achieve a wear-resistant effect when the positioning ring 200 is clamped on the outside of the handle 103.

[0036] A rubber inner ring 207 surrounds the outer surface of the handle 103, and a limiting ring 206 fits against the top and bottom of the handle 103.

[0037] The interface 104 component also includes a control base 102 and an interface 104. The control base 102 is disposed on the inner surface of the docking seat 100, the handle 103 is fixed to the top of the control base 102, and the interface 104 is fixed to one end of the outer surface of the docking seat 100.

[0038] There are four interfaces 104 between the docking seats 100, which can be connected to different infusion bottles or infusion tubes respectively. When the infusion starts, the medicine in each infusion bottle flows to the corresponding interface 104 of the four-way connector under the action of gravity through the infusion tubes they are connected to, and then converges in the internal channel of the four-way connector.

[0039] Working principle: First, there are four interfaces 104 between the docking seats 100, which can be connected to different infusion bottles or infusion tubes. When the infusion begins, the liquid in each infusion bottle flows under the action of gravity through its respective infusion tube to the corresponding interface 104 of the four-way connector. Then, it converges in the internal channel of the four-way connector. The user can rotate the handle 103 to allow the liquid to be delivered through the four-way interface 104. The handle 103 extends outwards with multiple angles, allowing the user to easily rotate the infusion docking device by holding the extended angles of the handle 103. The damping ring 204 can move outside the damping rod 202 and has a damping effect. As a result, the handle 103 can achieve precise positioning and adjustment during rotation. By pushing, the positioning ring 200 can be tightly clamped to the outside of the handle 103, quickly locking the angle. Once the angle of the handle 103 is locked, the positions of each channel of the infusion dock are relatively fixed, effectively preventing backflow of the medicine caused by accidental rotation of the handle 103. In actual infusion, even if subjected to certain external impacts or vibrations, the locking effect of the positioning ring 200 can ensure that the angle of the handle 103 remains stable, providing a strong guarantee for the safety and stability of the infusion process and achieving the purpose of preventing backflow.

[0040] Please see Figure 1 , Figure 2 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0041] The mounting components include a connecting pipe 300, a retaining ring 301, an extension ring 302, a rubber post 303, a snap-fit ​​groove 304, and a snap-fit ​​block 306. The connecting pipe 300 is embedded at one end of the outer surface of the interface 104. The retaining ring 301 is fixed to the outer surface of the interface 104. The extension ring 302 is disposed on the outer surface of the retaining ring 301 and surrounds the outer surface of the connecting pipe 300. The snap-fit ​​groove 304 is opened at one end of the outer surface of the extension ring 302. The snap-fit ​​block 306 is fixed to the outer surface of the connecting pipe 300 and inserted into the inside of the snap-fit ​​groove 304. The rubber post 303 is adhered to the inner wall of the snap-fit ​​groove 304.

[0042] Install the connecting pipe 300 on the outside of the interface 104, insert the snap-fit ​​block 306 into the inside of the snap-fit ​​groove 304, and block the outer surface of the snap-fit ​​block 306 with the rubber post 303 to fix the snap-fit ​​block 306, thus completing the installation of the connecting pipe 300.

[0043] The mounting components also include a slot 305 and an insert plate 307. The slot 305 is formed inside the retaining ring 301, and the insert plate 307 is fixed to one end of the connecting tube 300 and inserted into the slot 305.

[0044] Insert plate 307 is inserted into slot 305 to make the connection tube 300 and interface 104 correspond.

[0045] Working principle: When the connecting tube 300 needs to be installed onto the interface 104 of the infusion four-way connector, the insert plate 307 is accurately aligned with the slot 305. The user will first perform a precise initial alignment operation. As the insert plate 307 is inserted into the slot 305, the locking block 306 at the end of the connecting tube 300 will also move towards the locking groove 304 at the interface 104. When the locking block 306 reaches the position of the locking groove 304, the medical staff will continue to apply a certain amount of pressure to make the locking block 306 smoothly insert into the locking groove 304. The design of the 06 and the snap-fit ​​groove 304 adopts a matching shape and size, which can fit tightly into it to form a reliable mechanical connection. The rubber post 303 has good elasticity and flexibility. When the snap-fit ​​block 306 is inserted, the rubber post 303 will be squeezed and deformed. The deformed rubber post 303 will tightly adhere to the outer surface of the snap-fit ​​block 306, generating a large friction force. This friction force can effectively prevent the snap-fit ​​block 306 from coming out of the snap-fit ​​groove 304, thereby firmly fixing the snap-fit ​​block 306.
