Description

Technical Field

[0001] This utility model relates to the field of infusion set technology, specifically to an anti-bubble and light-blocking infusion set. Background Technology

[0002] Compared to ordinary infusion sets, light-proof infusion sets have the same components, the difference being that they are darker in color, providing a certain degree of light protection. For infusion sets, the drip chamber is an essential component. Currently, clinically used drip chambers typically have the inlet at the top and the outlet at the bottom. For convenience, infusion sets used in medical institutions often contain air bubbles. While air bubble filters are usually installed on the infusion tubing, the fundamental problem of air bubble generation remains unsolved. During infusion, as the liquid drips from the infusion tubing into the drip chamber, the height of the drip chamber means that each drop, impacting the liquid surface, easily generates air bubbles. Therefore, this paper provides an anti-air bubble, light-proof infusion set to solve these problems. Utility Model Content

[0003] To solve the problems mentioned above in the background technology, the technical solution adopted by this utility model is: an anti-bubble and light-proof infusion set, which includes: an infusion set drip chamber, a first rigid tube connected to one side of the upper end of the infusion set drip chamber, a second rigid tube slidably sleeved inside the lower end of the first rigid tube, a support rod fixedly connected to the outer side of the bottom circumference of the second rigid tube, and a floating ring fixedly connected to the bottom of the second rigid tube through the support rod.

[0004] As a preferred embodiment of this utility model, the second rigid tube extends into the drip chamber of the infusion set, the outer diameter of the second rigid tube is the same as the inner diameter of the first rigid tube, and both the outer diameter of the second rigid tube and the inner diameter of the first rigid tube are smooth surfaces.

[0005] As a preferred embodiment of this utility model, the upper end of the drip chamber of the infusion set is connected to an infusion tube through a first rigid tube, the bottom of the drip chamber of the infusion set is directly connected to an infusion tube, and the infusion tube at the upper end of the drip chamber of the infusion set is connected to a bottle stopper puncture needle.

[0006] As a preferred embodiment of this utility model, the number of support rods is four, the floating ring has a hollow structure inside, and the outer diameter of the floating ring is smaller than the inner diameter of the infusion set drip chamber.

[0007] As a preferred embodiment of this invention, the bottom of the second rigid tube is higher than the top of the floating ring, and the inner diameter of the second rigid tube is smaller than the inner diameter of the infusion tube.

[0008] As a preferred embodiment of this utility model, the infusion tube connector adjuster below the drip chamber of the infusion set has a precision filter connected to its bottom via an infusion tube, and an infusion needle connected to the bottom of the precision filter via a pipe.

[0009] As a preferred embodiment of this utility model, the first rigid tube, the second rigid tube, the support rod, and the floating ring are all made of transparent material.

[0010] This invention has the following advantages: the floating ring can always float on the liquid surface in the drip chamber of the infusion set, thereby ensuring that the effective distance between the bottom of the second rigid tube and the liquid surface in the drip chamber of the infusion set remains constant, effectively controlling the distance the drip falls to the liquid surface in the drip chamber of the infusion set, and effectively avoiding the formation of air bubbles when the drip falls on the liquid surface by effectively shortening the drop height.

In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Please refer to the following: Figures 1-3 This utility model discloses an anti-bubble and light-blocking infusion set, comprising: an infusion set drip chamber 2, a first rigid tube 3 connected to one side of the upper end of the infusion set drip chamber 2, a second rigid tube 4 slidably sleeved inside the lower end of the first rigid tube 3, a support rod 5 fixedly connected to the outer side of the bottom circumference of the second rigid tube 4, and a floating ring 6 fixedly connected to the bottom of the second rigid tube 4 through the support rod 5.

[0019] Combination Figure 1 and Figure 2 As shown, the second rigid tube 4 extends into the inside of the infusion set drip chamber 2. The outer diameter of the second rigid tube 4 is the same as the inner diameter of the first rigid tube 3, and both the outer and inner surfaces of the second rigid tube 4 and the first rigid tube 3 are smooth, which facilitates the sliding of the second rigid tube 4 along the inner wall of the first rigid tube 3. The upper end of the infusion set drip chamber 2 is connected to the infusion tube 1 through the first rigid tube 3, and the bottom of the infusion set drip chamber 2 is directly connected to the infusion tube 1. The infusion tube 1 at the upper end of the infusion set drip chamber 2 is connected to the bottle stopper puncture needle 7.

[0020] The system includes four support rods 5, a hollow floating ring 6 with an outer diameter smaller than the inner diameter of the drip chamber 2, a second rigid tube 4 with its bottom higher than the top of the floating ring 6, and an inner diameter smaller than the inner diameter of the infusion tube 1. Below the drip chamber 2 is an infusion tube 1 connector adjuster 8. The bottom of the adjuster 8 is connected to a precision filter 9 via the infusion tube 1, and the bottom of the precision filter 9 is connected to an infusion needle 10 via a pipe. The first rigid tube 3, the second rigid tube 4, the support rods 5, and the floating ring 6 are all made of transparent material, allowing personnel to visually observe the dripping at the bottom of the second rigid tube 4.

[0021] Specifically, when this invention is used, after the liquid in the infusion bottle enters the drip chamber 2 of the infusion set through the infusion tube 1, the floating ring 6 automatically floats up under the buoyancy of the liquid, causing the second rigid tube 4 to rise along the inner wall of the first rigid tube 3. At this time, the liquid in the infusion tube 1 first passes through the first rigid tube 3 and then enters the second rigid tube 4, finally dripping from the bottom of the second rigid tube 4 onto the storage liquid surface inside the drip chamber 2. Since the floating ring 6 can always float on the liquid surface in the drip chamber 2, the effective distance between the bottom of the second rigid tube 4 and the liquid surface in the drip chamber 2 remains constant, thereby effectively controlling the distance the drip falls to the liquid surface in the drip chamber 2. By effectively shortening the drop height, the impact of the drip on the liquid surface and the generation of air bubbles is effectively avoided.

[0022] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0023] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
