Description

Technical Field

[0001] This utility model belongs to the field of infusion connector technology, specifically relating to a three-way connector infusion connector connection structure. Background Technology

[0002] Infusion connectors are connecting devices used to connect infusion tubing and infusion equipment. They play important functions such as connection, sealing, regulation, and prevention of contamination during infusion. A three-way connector is a device that can connect multiple channels simultaneously to achieve drug delivery in various channels. Different drugs, nutritional solutions, or flushing solutions can be delivered to the patient through three channels, and the infusion ratio and rate of each fluid can be flexibly adjusted according to treatment needs. At the same time, medication can be added to one channel, another channel is used to monitor infusion pressure or blood return, and the third channel can be used as a backup channel or for infusing other special drugs.

[0003] In the existing technology, when using a three-way connector for infusion, the cap of the corresponding connection port of the three-way connector needs to be removed before connecting the infusion connector. However, after the cap is removed, the storage environment cannot reach a sterile state, so it cannot be used again. Moreover, after the infusion connector is removed, the corresponding connection port of the three-way connector cannot reach a sterile state, which in turn makes the three-way connector unusable, resulting in waste of consumables and poor practicality.

Additionally, "multiple" and "several" mean two or more, unless otherwise explicitly specified.

[0018] Please refer to the following: Figures 1 to 4 The connection structure of the three-way connector infusion joint provided by this utility model is now described. The three-way connector infusion joint connection structure includes a three-way body 10 with three connection ports. Multiple connecting caps 20 are provided, each cap 20 being detachably connected to each connection port. Each connecting cap 20 has a self-sealing part. Multiple infusion joint bodies 30 are provided, each corresponding to one of the connecting caps 20. After each infusion joint body 30 is connected to the corresponding connecting cap 20, the self-sealing part is released, and communication with the corresponding connection port of the three-way body 10 is established.

[0019] The three-way connector infusion joint connection structure provided in this embodiment, compared with the prior art, includes a three-way body 10, a connecting cap 20, and an infusion joint body 30. This allows the connection port of the three-way body 10 to be sealed and protected by the connecting cap 20 when not in use, preventing external contamination. When infusion is needed, the infusion joint body 30 can be easily connected to the connecting cap 20 to achieve communication. This is simple and safe to operate, greatly reducing the risk of contamination at the connection port and minimizing the possibility of patient infection. Furthermore, the detachable connection method allows medical staff to flexibly adjust the infusion route according to actual needs, improving work efficiency.

[0020] The three-way connector infusion fitting connection structure provided in this embodiment has the following connection scenarios: When the three-way body 10 only needs to connect to one infusion fitting body 30, only one connecting cap 20 is needed. The original sealing cap 15 on the three-way body 10 needs to be removed, the connecting cap 20 is installed, and finally the infusion fitting is installed. When the three-way body 10 needs to connect to two infusion fitting bodies 30, two connecting caps 20 are needed. The original sealing cap 15 on the three-way body 10 needs to be removed, the connecting cap 20 is installed on the corresponding connection port, and finally the infusion fitting is installed. When the three-way body 10 needs to connect to three infusion fitting bodies 30, three connecting caps 20 are needed. The original sealing cap 15 on the three-way body 10 needs to be removed, the connecting cap 20 is installed on the corresponding connection port, and finally the infusion fitting is installed.

[0021] In some embodiments, the aforementioned three-way body 10 can be adopted as follows: Figure 1 The structure shown. See also Figure 1 The tee body 10 includes: a main connecting pipe 11, a side connecting pipe 12, a main connecting connector 13, and a side connecting connector 14. The main connecting pipe 11 has a main connecting cavity. One end of the side connecting pipe 12 is connected to the main connecting pipe 11, and the other end of the side connecting pipe 12 extends outward. The axis of the side connecting pipe 12 is perpendicular to and horizontally arranged with the axis of the main connecting pipe 11. The side connecting pipe 12 has a side connecting cavity that communicates with the main connecting cavity. Two main connecting connectors 13 are provided, respectively located at both ends of the main connecting pipe 11. The side connecting connector 14 is located on the extended end of the side connecting pipe 12.

[0022] Both the main connector 13 and the side connector 14 have connection ports.

[0023] This three-way connector 10 structure enables multi-directional infusion connections to meet diverse infusion needs. The vertical arrangement of the main connecting tube 11 and the side connecting tube 12 allows for more flexible infusion tubing layout, facilitating operation by medical staff. When administering multiple medications simultaneously, different infusion bottles can be connected to the two ends of the main connecting tube 11, while the side connecting tube 12 can be connected to a syringe for injecting specific drugs. This allows for the simultaneous infusion of multiple medications, improving therapeutic efficacy. It increases the flexibility and versatility of infusion services, better meeting clinical treatment needs. Furthermore, the design of each connector ensures a more stable infusion tubing connection, reducing the risk of leakage.

[0024] The three-way body 10 can also be equipped with a three-way valve, which mainly consists of a valve body, a valve core, and a drive device (such as manual, electric, or pneumatic). The drive device controls the movement or rotation of the valve core within the valve body, changing the relative position between the valve core and the valve body, thereby opening or closing different channels to control the flow direction of the fluid. For example, in a T-type three-way valve, when the valve core is in a certain position, fluid can enter from one inlet and exit from one outlet. After moving the valve core, the fluid can flow out from the other outlet.

[0025] In some embodiments, the infusion connector body 30 described above can be adopted as follows: Figure 2 , Figure 3 The structure shown. See also Figure 2 , Figure 3 Each infusion connector body 30 includes: a protective housing 31, a connecting housing 32, and a diaphragm 33. The protective housing 31 has a protective cavity extending through both ends of the protective housing 31. The connecting housing 32 is detachably connected to the protective housing 31. One end of the connecting housing 32 extends into the protective cavity, and the extended end of the connecting housing 32 is spaced apart from the protective housing 31. The other end of the connecting housing 32 extends outward, and the connecting housing 32 has a communicating cavity extending through both ends of the connecting housing 32. The diaphragm 33 is disposed within the protective cavity and covers the extended end of the connecting housing 32. The diaphragm 33 is used to keep the extended end of the connecting housing 32 sterile.

[0026] The protective housing 31 and the separator 33 effectively protect the insertion end of the connecting housing 32, preventing contamination before use and ensuring the sterility of the infusion connector body 30. When the infusion connector body 30 is not in use, the separator 33 seals the insertion end of the connecting housing 32 within the protective cavity, maintaining its sterility. This improves the safety and reliability of the infusion connector body 30 and reduces adverse infusion reactions caused by contamination.

[0027] In some embodiments, the connecting cap 20 may be adopted as follows: Figure 2 , Figure 4 The structure shown. See also Figure 2 , Figure 4 Each connecting cap 20 includes a cap body 21 and an isolation membrane 22. One end of the cap body 21 is detachably connected to the protruding end of the connecting housing 32, and the other end is detachably connected to the corresponding connecting port. The isolation membrane 22 is disposed on the cap body 21 and located at the connecting end of the cap body 21 and the connecting housing 32. The isolation membrane 22 is used to isolate the corresponding connecting port when the cap body 21 and the connecting housing 32 are separated. The isolation membrane 22 is a self-sealing part.

[0028] The isolation membrane 22, acting as a self-sealing component, automatically seals the connection port when the connecting cap 20 is separated from the infusion connector body 30, preventing external contamination from entering the tee body 10. When the infusion connector body 30 is connected to the connecting cap 20, the protruding end of the connecting housing 32 passes through the isolation membrane 22, releasing the seal and allowing the infusion passage to open. After the infusion is completed, separating the infusion connector body 30 from the connecting cap 20 causes the isolation membrane 22 to automatically reset, isolating the connection port. This further enhances the sealing and safety of the connection port, reducing the risk of infection. Simultaneously, the self-sealing function simplifies operation, eliminating the need for additional sealing measures.

[0029] In some embodiments, the aforementioned separator 22 may be adopted as follows: Figure 2 , Figure 4 The structure shown. See also Figure 2 , Figure 4 The isolation membrane 22 is provided with multiple flexible opening and closing flaps 221 through which the protruding end of the connecting housing 32 passes. Each flexible opening and closing flap 221 is used to reset the connecting housing 32 and the cap body 21 when separated, so as to isolate the corresponding connection port.

[0030] The flexible opening and closing flap 221 design allows the protruding end of the connecting housing 32 to smoothly pass through the isolation membrane 22, and also enables it to quickly return to its original position upon separation, achieving effective isolation of the connection port. When the protruding end of the connecting housing 32 passes through the isolation membrane 22, the flexible opening and closing flap 221 is opened. After the connecting housing 32 separates from the cap body 21, the flexible opening and closing flap 221 quickly returns to its original position under its own elasticity, resealing the connection port. This improves the sealing performance and reliability of the isolation membrane 22, ensuring that the connection port remains isolated when not in use. Simultaneously, the design of the flexible opening and closing flap 221 makes the connection operation smoother and reduces resistance.

[0031] In some embodiments, the protective housing 31 may be adopted as follows: Figure 2 , Figure 3 The structure shown. See also Figure 2 , Figure 3 The protective housing 31 and the connecting housing 32 are made of transparent material.

[0032] The transparent protective housing 31 and connecting housing 32 allow medical staff to easily observe the internal conditions, such as the flow of the liquid and the presence of air bubbles. This improves the visibility and safety of the infusion process, making it easier for medical staff to detect and address problems promptly. Furthermore, the transparent material meets the hygiene requirements for medical devices in the medical industry.

[0033] In some embodiments, the separator 33 may be adopted as follows: Figure 2 , Figure 3 The structure shown. See also Figure 2 , Figure 3The separator 33 is made of flexible material.

[0034] The flexible separator membrane 33 can better fit the extended end of the connecting housing 32, ensuring its sealing effect, while being less prone to damage during connection and separation. This improves the sealing performance and durability of the separator membrane 33, reducing the risk of contamination caused by damage to the separator membrane 33. At the same time, the flexible material also makes operation more convenient.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
