Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a connection auxiliary device for multi-channel infusion. Background Technology

[0002] Traditional infusion tubing is known to have limitations, typically only capable of delivering a single type of fluid. However, in complex medical scenarios, such as during surgery or emergency resuscitation, it is often necessary to deliver multiple medications or fluids to patients simultaneously. This necessitates a device that can flexibly handle various infusion needs to meet medical requirements. Some infusion tubing systems are equipped with multiple inlet channels and multiple extension tubes with excellent sealing and stability to ensure that various fluids do not interfere with or contaminate each other, guaranteeing the safety and reliability of the infusion. This enables the simultaneous delivery of multiple fluids, greatly improving infusion efficiency and convenience.

[0003] However, in actual use, due to the small diameter of the infusion tubing, when multiple infusion tubings are used simultaneously, they are prone to tangling, leading to interruptions in the infusion. This not only requires medical staff to sort them out, but in severe cases, it can also affect the patient's treatment. Existing equipment lacks measures to restrain the infusion tubing. Therefore, a connection auxiliary device for multi-pathway infusion is proposed as a further improvement. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a connection auxiliary device for multi-channel infusion to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connection auxiliary device for multi-channel infusion, the auxiliary device comprising: an infusion extension tube and an anti-dislodgement mechanism;

[0006] One end of the infusion extension tube is detachably connected to the outer shell of the multi-channel infusion set, and the other end of the infusion extension tube is sleeved on the end of the syringe; the anti-dislodgement mechanism is provided at the end of the infusion extension tube near the syringe.

[0007] The infusion extension tube is spiral-shaped.

[0008] The infusion extension tube is made of a highly elastic, repositionable rubber material.

[0009] Furthermore, the outer surface of the infusion extension tube is coated with a material distinguished by color.

[0010] Furthermore, the spiral extension tube has at least 5 turns.

[0011] Furthermore, the helical pitch of the spiral-shaped infusion extension tube is set to a constant pitch.

[0012] Furthermore, the spiral pitch of the infusion extension tube is set to a variable pitch.

[0013] Furthermore, the anti-detachment mechanism includes: a fixed base and a tubular clamping sleeve.

[0014] One end of the fixing seat is fixedly installed on the side of the end of the infusion extension tube, and the other end of the fixing seat is rotatably connected to one side of the two tubular clamping sleeves through a rotating shaft. The two tubular clamping sleeves are clamped on the end of the syringe, and the side of the two tubular clamping sleeves away from the fixing seat is connected by a fixing member.

[0015] Furthermore, a fixing clip is fixedly installed on the surface of the infusion extension tube, a T-shaped fixing block is fixedly installed on one side of the fixing clip, and a T-shaped sliding groove is opened on the other side of the fixing clip. The T-shaped fixing block of one fixing clip is inserted into the T-shaped sliding groove of the adjacent fixing clip; a clamping block that contacts the infusion extension tube is fixedly connected inside the fixing clip by a return spring.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] Compared with existing technologies, the infusion extension tube in the auxiliary device is made of a highly elastic, repositionable material. Its repositioning is achieved by spiraling and coiling, thus saving space and providing mutual restraint; therefore, it has the function of organizing the tubing. An anti-detachment mechanism is used to connect the infusion extension tube to the syringe, preventing the syringe and the infusion extension tube from easily breaking off due to external forces. To improve the anti-winding effect, the fixing clip of the auxiliary device is used to fix the infusion extension tube. When multiple infusion extension tubes are used, the fixing clip maintains a fixed distance between the multiple infusion extension tubes, thus improving the anti-winding effect.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] As attached Figure 1-4 The diagram shows a connection auxiliary device for multi-channel infusion, the auxiliary device including: an infusion extension tube 1 and an anti-dislodgement mechanism 2;

[0029] One end of the infusion extension tube 1 is detachably connected to the outer shell of the multi-channel infusion set, and the other end of the infusion extension tube 1 is sleeved on the end of the syringe 3; the anti-dislodgement mechanism 2 is provided at the end of the infusion extension tube 1 near the syringe 3.

[0030] The infusion extension tube 1 is designed to be spiral-shaped;

[0031] The infusion extension tube 1 is made of a highly elastic, repositionable rubber material.

[0032] In this invention, the characteristics of the spiral infusion extension tube 1 that can be reset after being straightened are fully utilized. When multiple infusion extension tubes 1 are used for infusion, in order to avoid entanglement between them, and after being straightened into a bundle, because they have the same length, the same spiral pitch and the same number of turns, it is difficult for them to entangle after being reset; and by using their spiral coils together, space is saved.

[0033] In a preferred embodiment, as shown in the appendix Figure 1-4 As shown, the outer surface of the infusion extension tube 1 is coated with a material that is distinguished by color; this makes it easier to identify and locate the corresponding infusion extension tube 1.

[0034] In a preferred embodiment, as shown in the appendix Figure 1-4 As shown, the spiral extension tube 1 has at least 5 turns; this ensures that the extension tube 1 saves space and prevents tangling when spiraling.

[0035] In a preferred embodiment, as shown in the appendix Figure 1-4 As shown, the spiral pitch of the infusion extension tube 1 is set to a constant pitch so that it can be easily straightened into a bundle.

[0036] In a preferred embodiment, as shown in the appendix Figure 1-4 As shown, the spiral pitch of the spiral infusion extension tube 1 is set to a variable pitch to save space; the pitch can be set to gradually increase.

[0037] In a preferred embodiment, as shown in the appendix Figure 1-4 As shown, the anti-falling mechanism 2 includes: a fixed base 21 and a tubular clamping sleeve 22.

[0038] One end of the fixing seat 21 is fixedly installed on the side of the end of the infusion extension tube 1. The other end of the fixing seat 21 is rotatably connected to one side of the two tubular clamping sleeves 22 through a rotating shaft. The two tubular clamping sleeves 22 are clamped at the end of the syringe 3. The side of the two tubular clamping sleeves 22 away from the fixing seat 21 is connected by a fixing member 23.

[0039] Among them, the fastener 23 can be a snap fastener to directly fix the two tubular clamping sleeves 22;

[0040] Alternatively, bolts can be used to fix the two tubular clamping sleeves 22 together, and the tightness can be adjusted.

[0041] In a preferred embodiment, as shown in the appendix Figure 1-4 As shown, a fixing clip 4 is fixedly installed on the surface of the infusion extension tube 1. A T-shaped fixing block 41 is fixedly installed on one side of the fixing clip 4, and a T-shaped sliding groove 42 is opened on the other side of the fixing clip 4. The T-shaped fixing block 41 of one fixing clip 4 is inserted into the T-shaped sliding groove 42 of the adjacent fixing clip 4. The clamping block 44 that contacts the infusion extension tube 1 is fixedly connected inside the fixing clip 4 by a reset spring 43.

[0042] Among them, multiple infusion extension tubes 1 can be connected at the same position by fixing clips 4, thereby ensuring that the spacing between multiple infusion extension tubes 1 is fixed and improving the anti-tangling effect;

[0043] The working principle of this utility model is as follows: When in use, medical staff connect the two ends of the infusion extension tube 1 to the multi-channel infusion set and the syringe 3 respectively; when connecting the syringe 3, the two tubular clamping sleeves 22 are clamped by the fixing piece 23 to prevent the infusion extension tube 1 from detaching from the syringe 3.

[0044] If there are multiple infusion extension tubes 1, each additional infusion extension tube 1 will straighten all the infusion extension tubes 1 used into a bundle. After being loosened, the multiple infusion extension tubes 1 are spirally coiled together using a spiral-shaped, highly elastic, and repositionable rubber material. Because they are the same length, the same pitch and the same number of turns, they are unlikely to entangle with each other, thus saving space.

[0045] If an improved anti-tangling effect is required, when all the infusion extension tubes 1 used are straightened into a bundle, the fixing clips 4 on each infusion extension tube 1 are joined together and then released, and the multiple infusion extension tubes 1 are reset and spirally coiled together; due to the fixing clips 4, there is a fixed distance between the multiple infusion extension tubes 1.
