Existing tee infusion devices are prone to blockage when different drugs are injected, resulting in interruption of fluid rehydration or rapid blockage of central venous catheter during treatment, secondary clinical adverse events.
An anti-blocking tee infusion device is designed, using a combination of a dual filter and a pressure sensing column. The filter is initially filtered at the input end of the medicine liquid, and the mixing end is secondary filtered to prevent flocs from entering the vein; the pressure sensing column displaces when the filter is blocked, remind the nursing staff to change the infusion device to prevent blockage.
Through the design of the dual filter and pressure sensing column, the possibility of flocs entering the central vein is reduced, and caregivers are promptly reminded to change the infusion device, avoiding interruption of fluid replenishment and the occurrence of clinical adverse events, and ensuring the safety and stability of the patient's treatment process.

Abstract
Description
Technical Field
[0001] The utility model relates to an anti-blocking three-way infusion set, belonging to the technical field of medical devices. Background Art
[0002] Based on the retention of a central venous catheter, by connecting one or more three-way fluid infusion sets, it is possible to simultaneously infuse drugs with different therapeutic effects. Especially important drugs such as adrenaline, noradrenaline, and dobutamine for maintaining blood pressure and improving cardiac function can control the infusion rate while ensuring the input of such important drugs; even for critically ill patients with multiple indwelling central venous catheters, it is inevitable that multiple drugs may need to be pumped in simultaneously through a three-way infusion set; however, when there are drugs without obvious incompatibility taboos, even when pumped in from different three-way infusion sets, unpredictable floccules or crystals may appear. Once this situation occurs, it may lead to the inability to continue infusing the fluid or drugs for maintaining the patient's survival. When the blockage range is relatively large, it may cause the central venous catheter to be quickly blocked and unusable, thus secondary clinical adverse events, especially when not detected in time. Summary of the Invention
[0003] The purpose of the utility model is to solve the technical problem that the existing three-way infusion set is prone to blockage when different drugs are input. The utility model provides an anti-blocking three-way infusion set, and the pressure sensing column provided on the anti-blocking three-way infusion set can play a prompting role, enabling nursing staff to timely discover a three-way infusion set that may have or has already had a blockage, so as to timely replace the three-way infusion set or stop or replace the drug infused from this three-way infusion set, ensuring the safety and stability of the patient's treatment process.
[0004] In order to achieve the above purpose, the utility model provides an anti-blocking three-way infusion set, including a three-way pipe body. The three-way pipe body includes a main pipe, a branch pipe, and a three-way knob. The main pipe and the branch pipe are vertically connected through the three-way knob to form a T-shaped structure, and the inside of the three-way pipe body and the three-way knob are both in a T-shaped structure and communicate with each other; filters are respectively provided at both ends of the main pipe and the end of the branch pipe, and the filters are detachably installed at the end of the main pipe or the branch pipe; the three-way pipe body includes a first liquid medicine input end and a second liquid medicine input end. The first liquid medicine input end is provided at one end of the main pipe, the second liquid medicine input end is provided at the other end of the main pipe or the end of the branch pipe, and pressure sensing columns are respectively provided at the first liquid medicine input end and the second liquid medicine input end.
[0005] Preferably, the filter is installed in a detachable joint, and the connection mode between the detachable joint and the main pipe and the branch pipe is a detachable connection.
[0006] Preferably, the material of the filter is stainless steel, nylon, or high molecular material.
[0007] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0008] A non-blocking three-way infusion set provided by the present utility model can reduce the direct entry of floccules into the central vein by setting a double filter. At the same time, when the blocked area of the filter gradually increases, resulting in an increase in the pressure of the three-way infusion set, the set pressure sensing column displaces, which can timely remind the nursing staff to replace the corresponding three-way infusion set, thereby avoiding the interruption of fluid infusion or other major clinical adverse events. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In order to make the present utility model more obvious and understandable, preferred embodiments are given below in conjunction with the accompanying drawings for detailed description as follows.
[0012] Embodiment
[0013] This embodiment provides a non-blocking three-way infusion set, as Figure 1As shown in the figure, it includes a tee pipe body 1, the tee pipe body 1 includes a main pipe 2, a branch pipe 3 and a tee knob 4, and the main pipe 2 and the branch pipe 3 are vertically connected by the tee knob 4 to form a T-shaped structure; the inside of the tee pipe body 1 and the tee knob 4 are both in a T-shaped structure and communicate with each other; filters 5 are respectively provided at both ends of the main pipe 2 and the port of the branch pipe 3, which are respectively used for primary filtration at the liquid medicine input end and secondary filtration at the liquid medicine mixing end. The filter 5 is detachably connected to the main pipe 2 and the branch pipe 3 through a detachable joint 6. Specifically, a threaded connection can be adopted between the detachable joint 6 and the main pipe 2 and the branch pipe 3. The material of the filter 5 is stainless steel, nylon or polymer material, such as polymer materials like polytetrafluoroethylene. In actual use, a filter of a suitable material is selected according to the physical and chemical properties of the drug. The aperture of the filter is in the micron range, and the aperture of the filter can be specifically set at 1-5 μm. In order to prevent blockage, the detachable joint 6 can be removed after each use, and a new filter can be replaced and then used for the next infusion; both ends of the main pipe 2 are respectively set as the first liquid medicine input end and the second liquid medicine input end. It is also possible to use one end of the main pipe as the first liquid medicine input end, the other end as the liquid medicine mixing end, and the branch pipe as the second liquid medicine input end. Correspondingly, pressure sensing columns 7 are respectively provided at the first liquid medicine input end and the second liquid medicine input end. The pressure sensing column 7 is arranged in front of the filter 6 (the front and back positions are relative and are defined according to the sequence of the liquid medicine flowing through. The position where the liquid medicine first flows through is the relative front end, and the position where the liquid medicine then flows through is the relative back end). The pressure sensing column 7 can be a green liquid column encapsulated in the pipe (it can also be red or other colors). When blockage occurs, the pressure at the liquid medicine input end increases, thereby causing the pressure sensing column 7 to move, indicating that the liquid medicine is blocked, and reminding the nursing staff that the corresponding three-way infusion set needs to be replaced to avoid interruption of fluid infusion or other major clinical adverse events.
[0014] The above embodiments are only the preferred embodiments of the present invention, and do not impose any formal or substantial limitations on the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the premise of the present invention, several improvements and supplements can still be made, and these improvements and supplements should also be regarded as the protection scope of the present invention.
