Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a multi-port infusion tube. Background Technology

[0002] An infusion tubing is a medical device used to deliver liquid medications from a container into a patient's vein. It typically consists of components such as tubing, needles, and connectors, which allow medications to be introduced from a storage bottle or bag into the patient's vein.

[0003] Existing infusion devices generally use a single connecting tube, which can only deliver one type of medication at a time. Changing the medication after each infusion is time-consuming and requires calling medical staff to change the medication bottle, making the operation cumbersome. Therefore, a multi-port infusion connecting tube is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a multi-port infusion tube to solve the problems mentioned in the background art, where existing infusion devices are generally single-port tubes that can only deliver one type of medication at a time. After each infusion of one type of medication, it is time-consuming to change the medication, and it is also cumbersome to call medical staff to change the medication bottle.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a multi-port infusion connection tube, comprising:

[0007] An infusion connection tube, comprising an infusion hose, a fitting, and a four-way fitting;

[0008] The pipe fitting is sleeved on one end of the infusion tubing, and the other end of the pipe fitting is screwed onto one end of the four-way connector.

[0009] The positioning assembly includes a support plate, an arc-shaped threaded plate, a limit cap, a fixing plate, a connecting shaft, a torsion spring, and an arc-shaped clamping plate.

[0010] The support plate is attached to the lower surface of the four-way connector. There are four arc-shaped threaded plates, which are fixed in the middle of the support plate and are distributed symmetrically in a ring. The limiting cap is screwed to the upper end of the arc-shaped threaded plate. The fixing plate is fixed to one end of the support plate surface. The connecting shaft is fixed to the side of the fixing plate. The torsion spring is sleeved on the connecting shaft. The arc-shaped clamp is sleeved on the connecting shaft.

[0011] Furthermore, there are four sets of infusion tubing and fittings, which are respectively connected to the four joints of the four-way connector.

[0012] Furthermore, there are four sets of fixed plates, connecting shafts, torsion springs and arc-shaped clamps, which are symmetrically distributed in a ring on the support plate, and the arc-shaped clamps are respectively clamped on the four pipe joints.

[0013] Furthermore, the infusion connecting tube also includes a valve and a needle;

[0014] The valve is fixed at three joints on the four-way connector, and the needle is fixed at one end of one of the three infusion tubing.

[0015] Furthermore, it also includes stabilizing components;

[0016] The stabilizing component includes a spring and a limiting plate;

[0017] One end of the spring is fixed to the inner top surface of the limiting cap, and the limiting plate is fixed to the other end of the spring.

[0018] Furthermore, the stabilizing component also includes grooves and rubber wheels;

[0019] The groove is formed on the lower surface of the limiting plate, and the rubber wheel is rotatably connected in the groove.

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] I. This utility model, through the positioning component, places the center of the four-way connector in the middle of the arc-shaped threaded plate on the support plate. The infusion tubing connector is pressed down, causing the arc-shaped clamp on the fixing plate to open. After the connector is inserted into the arc-shaped clamp, the torsion spring on the connecting shaft resets, causing the arc-shaped clamp to close. Then, the limiting cap is aligned with the arc-shaped threaded plate and tightened. The limiting cap presses the four-way connector onto the support plate. This design can provide rigid support and protection for the four-way connector and the tubing connector, avoiding accidental contact or damage, and preventing the catheter from coming out due to gravity.

[0022] II. In this utility model, the stabilizing component is set to align the arc-shaped threaded plate and tighten the limiting cap. As the limiting cap is tightened, the spring moves downward, which in turn moves the limiting plate downward. As the limiting cap rotates, the rubber wheel in the groove rotates on the upper surface of the four-way connector. This setting can prevent the limiting cap from pressing the four-way connector too tightly, which would affect the flow of liquid, and at the same time ensure the stability of the four-way connector.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] 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.

[0034] Please see Figures 1-4 As shown, this embodiment is a multi-port infusion connection tube, comprising:

[0035] The infusion connection tube includes an infusion hose 10, a tube connector 11, and a four-way connector 12.

[0036] The pipe fitting 11 is sleeved on one end of the infusion tubing 10, and the other end of the pipe fitting 11 is screwed onto one end of the four-way connector 12.

[0037] The infusion tubing 10 provides a liquid flow channel, with three tubes connected to different liquids and the other connected to an infusion set or collected into a bottle of liquid. The tube connector 11 and the four-way connector 12 serve as connections.

[0038] The positioning assembly includes a support plate 20, an arc-shaped threaded plate 21, a limit cap 22, a fixing plate 23, a connecting shaft 24, a torsion spring 25, and an arc-shaped clamping plate 26.

[0039] The support plate 20 is attached to the lower surface of the four-way connector 12. There are four arc-shaped threaded plates 21, which are fixed in the middle of the support plate 20 and are distributed in a ring symmetrically. The limit cap 22 is screwed to the upper end of the arc-shaped threaded plate 21. The fixing plate 23 is fixed to one end of the surface of the support plate 20. The connecting shaft 24 is fixed to the side of the fixing plate 23. The torsion spring 25 is sleeved on the connecting shaft 24. The arc-shaped clamp 26 is sleeved on the connecting shaft 24.

[0040] The support plate 20 provides support, the arc-shaped threaded plate 21 provides connection, the limit cap 22 provides limit, the fixing plate 23 provides support, the connecting shaft 24 facilitates the rotation of the arc-shaped clamping plate 26, the torsion spring 25 has a reset function, and the arc-shaped clamping plate 26 has a clamping function.

[0041] There are four sets of infusion tubing 10 and tubing connector 11, which are respectively connected to the four connectors of the four-way connector 12;

[0042] There are four sets of fixed plate 23, connecting shaft 24, torsion spring 25 and arc-shaped clamping plate 26, which are symmetrically distributed in a ring on the support plate 20, and the arc-shaped clamping plate 26 is clamped on the four pipe joints 11 respectively.

[0043] The infusion tubing also includes a valve 13 and a needle 14;

[0044] Valve 13 is fixed to three joints on four-way connector 12, and needle 14 is fixed to one end of three infusion tubing 10.

[0045] Valve 13 is used to open and close infusion tubing 10, and needle 14 serves as a connector.

[0046] Working principle:

[0047] The four-way connector 12 is placed in the middle of the arc-shaped threaded plate 21 on the support plate 20. The pipe connector 11 of the infusion tubing 10 is pressed down, which causes the arc-shaped clamp 26 on the fixing plate 23 to open. After the pipe connector 11 is inserted into the arc-shaped clamp 26, the torsion spring 25 on the connecting shaft 24 is reset, which causes the arc-shaped clamp 26 to close. Then the limit cap 22 is aligned with the arc-shaped threaded plate 21 and tightened. The limit cap 22 presses the four-way connector 12 onto the support plate 20.

[0048] This step provides rigid support and protection for the four-way connector 12 and the pipe connector 11, preventing accidental contact or damage, and also preventing the conduit from coming out due to gravity.

[0049] Please see Figure 5 This embodiment, based on the above embodiments, further includes:

[0050] The stabilizing component includes a spring 30 and a limiting plate 31;

[0051] One end of the spring 30 is fixed to the inner top surface of the limiting cap 22, and the limiting plate 31 is fixed to the other end of the spring 30;

[0052] Spring 30 has a compression function, and limiting plate 31 provides support and limitation.

[0053] The stabilizing components also include groove 32 and rubber wheel 33;

[0054] The groove 32 is formed on the lower surface of the limiting plate 31, and the rubber wheel 33 is rotatably connected in the groove 32;

[0055] The groove 32 serves as a storage compartment, and the rubber wheel 33 facilitates the rotation of the limiting plate 31.

[0056] Working principle:

[0057] Align the arc-shaped threaded plate 21 and tighten the limit cap 22. As the limit cap 22 is tightened, the spring 30 moves downward, which in turn moves the limit plate 31 downward. As the limit cap 22 rotates, the rubber wheel 33 in the groove 32 rotates on the upper surface of the four-way connector 12.

[0058] This step prevents the limit cap 22 from pressing the four-way connector 12 too tightly, which would affect the flow of liquid, and also ensures the stability of the four-way connector 12.
