Description

Technical Field

[0001] This utility model relates to the field of medical supplies technology, and in particular to a Y-shaped syringe that facilitates the examination of blood clots. Background Technology

[0002] In the treatment of hemodialysis patients, semi-permanent catheters serve as an important vascular access, playing a crucial role in connecting the patient to the dialysis machine. However, during clinical procedures, medical staff need to periodically draw blood from the patient to check for the presence of blood clots.

[0003] The traditional method involves directly injecting the aspirated blood onto gauze for observation. This means medical staff need to inject blood from a syringe onto the gauze, which absorbs the blood, while the thrombus fibers are exposed on the gauze. However, this method has drawbacks. When medical staff inject blood, it can easily cause blood splatter, which may contaminate the surrounding environment and increase the risk of cross-infection. Furthermore, after drawing blood with the syringe connected to the semi-permanent catheter, the syringe needs to be separated from the catheter and injected onto the gauze. The syringe tip is exposed to outside air, making it susceptible to external pathogens. Subsequent blood draws from the semi-permanent catheter can easily lead to infection of the catheter itself.

[0004] Therefore, a Y-shaped syringe that facilitates the examination of blood clots is needed to solve the above problems. Utility Model Content

[0005] This invention provides a Y-shaped syringe that facilitates the examination of blood clots, thus solving the aforementioned technical problems.

[0006] To solve the above-mentioned technical problems, this utility model provides a Y-shaped syringe for easy examination of thrombi, including a syringe and a semi-permanent catheter. A Y-shaped catheter is fixedly connected to the syringe orifice. One end of the Y-shaped catheter is spirally connected to the semi-permanent catheter, and the other end of the Y-shaped catheter is fixedly connected to a thrombus filter. A medical two-way valve I and a medical two-way valve II are fixedly installed in the middle of the two tubes separated by the Y-shaped catheter.

[0007] Preferably, the thrombus filter includes a transparent tube that is fixedly connected to the Y-shaped catheter, a filter screen is fixed in the middle of the transparent tube, and the inside of the transparent tube is filled with a moisture-absorbing filling material at the lower end of the filter screen.

[0008] Preferably, the moisture-absorbing filling material is a non-woven composite material, polyester fiber, or polyurethane porous membrane.

[0009] Preferably, the bottom of the transparent tube is fixedly connected to a vent.

[0010] Compared with related technologies, the Y-shaped syringe provided by this utility model, which facilitates the examination of blood clots, has the following beneficial effects:

[0011] This invention provides a method for aspirating blood using a syringe, then injecting the aspirated blood into a thrombus filter. The blood then passes through a Y-shaped catheter into a transparent tube, where it is filtered through a filter screen to remove thrombus fibers. The blood is then absorbed by the absorbent filling material after passing through the filter screen, allowing medical personnel to easily observe the presence of thrombi on the filter screen through the transparent tube. The entire operation is performed within a closed system, avoiding the risk of cross-infection caused by blood splashing. Furthermore, the syringe does not need to be separated from the semi-permanent catheter, preventing contact with external pathogens that could lead to infection of the semi-permanent catheter.

[0012] In summary, this device achieves seamless switching between "aspiration-detection" dual modes through a Y-shaped catheter and employs a multi-layer imaging structure, namely a filter layer + a moisture-absorbing layer, to enhance thrombus identification. Attached Figure Description

[0016] Implementation examples, by Figure 1-2 Provided is a Y-shaped syringe for easy viewing of thrombi, comprising a syringe 1 and a semi-permanent catheter 4. A Y-shaped catheter 2 is fixedly connected to the tip of the syringe 1. One end of the Y-shaped catheter 2 is spirally connected to the semi-permanent catheter 4, and the other end of the Y-shaped catheter 2 is fixedly connected to a thrombus filter 6. A medical two-way valve 3 and a medical two-way valve 5 are fixedly installed in the middle of the two tubes of the Y-shaped catheter 2.

[0017] Specifically, first, connect one end of the Y-shaped syringe to the patient's semi-permanent catheter, ensuring a tight, leak-free connection. At this point, both medical two-way valve 3 and medical two-way valve 5 are closed. Then, open medical two-way valve 3 and close medical two-way valve 5. Perform blood aspiration using syringe 1, drawing blood from the patient's body through syringe 1. The blood, affected by the negative pressure of syringe 1, flows out of the semi-permanent catheter, through the Y-shaped catheter 2, and into syringe 1. Once a sufficient amount of blood has been aspirated, close medical two-way valve 3. Next, open medical two-way valve 5, and the medical staff push syringe 1 to push the internal blood into the thrombus filter 6 for thrombus separation. The entire operation is performed within a closed system, avoiding the risk of blood splashing and cross-infection.

[0018] In this embodiment, the thrombus filter 6 includes a transparent tube 64 that is fixedly connected to the Y-shaped catheter 2. A filter screen 61 is fixed in the middle of the transparent tube 64, and the interior of the transparent tube 64 is filled with a moisture-absorbing filling material 62 at the lower end of the filter screen 61.

[0019] Specifically, blood enters the transparent tube 6 through the Y-shaped catheter, and the blood clots and fibers in the blood are filtered through the filter screen 61. The blood is then absorbed by the moisture-absorbing filling material 62 after passing through the filter screen 61, making it convenient for medical staff to observe whether there are blood clots on the filter screen through the transparent tube 64.

[0020] Among them, the moisture-absorbing filling material 62 is a non-woven composite material, polyester fiber, or polyurethane porous membrane; the moisture-absorbing filling material 62 is a non-woven composite material, that is, a multi-layer non-woven fabric combination, which can absorb blood, thereby better exposing the thrombus fibers on the filter screen 61.

[0021] The bottom of the transparent tube 64 is fixedly connected to a vent 63. This design allows for ventilation when necessary to maintain pressure balance within the pipe.

[0022] Working principle:

[0023] Preparation phase: First, connect one end of the Y-shaped syringe to the patient's semi-permanent catheter, ensuring a tight, leak-free connection. At this time, both medical two-way valve 3 and medical two-way valve 5 are in the closed position.

[0024] Blood aspiration: Open medical two-way valve 1 3 and close medical two-way valve 2 5. Perform blood aspiration through syringe 1. That is, draw blood from the patient's body through syringe 1. The blood is affected by the negative pressure of syringe 1 and flows out from the semi-permanent catheter. It then enters syringe 1 through Y-shaped catheter 2.

[0025] Preparation for thrombus observation: After a sufficient amount of blood is drawn back, close the medical two-way valve 1 3. Next, open the medical two-way valve 2 5. The medical staff push the syringe 1 to push out the blood inside. The blood enters the transparent tube 6 through the Y-shaped catheter. The blood passes through the filter screen 61 to filter the thrombus fibers in the blood. The blood comes into contact with the moisture-absorbing filling material 62 after passing through the filter screen 61. The moisture-absorbing filling material 62 is a non-woven composite material, that is, a combination of multiple non-woven fabrics, which can absorb the blood and make it convenient for the medical staff to observe whether there is a thrombus on the filter screen through the transparent tube 64.

[0026] The entire procedure was carried out within a closed conduit, avoiding the risks of blood splashing and cross-infection.
