[0002] A transfusion tube is a medical device used for blood transfusion procedures. It is primarily used to deliver blood or blood products from a donor to a recipient. In clinical treatment, when patients experience excessive blood loss (such as from trauma or surgery), severe anemia, or certain blood disorders, they require transfusions to replenish lost blood components and maintain normal physiological functions.

[0003] The aforementioned device lacks a structure for rapid air venting of the transfusion tube during use. This means that most existing transfusion tubes do not have an internal air venting mechanism. After the plasma bag is used up, air will enter the tube. If the transfusion bag is replaced at this time to continue transfusion, the needle hub and transfusion tube must be temporarily disconnected to vent the air before reconnecting for transfusion. During this process, the connection end is easily contaminated, which can affect the patient. Based on the shortcomings of existing technology, this utility model designs a transfusion set with an air vent. Utility Model Content

The exhaust mechanism 3 is provided to facilitate the discharge of air generated inside the transfusion tube 101 during blood transfusion.

[0029] Example 2

[0030] Please see Figure 3-5 The present invention provides the following technical solution:

[0031] The exhaust mechanism 3 includes an exhaust pipe 301, a filter screen 302, an upper chamber 303, a lower chamber 304, and a one-way membrane tube 305. The exhaust pipe 301 is located at the top of the latch 2. The filter screen 302 is installed inside the exhaust pipe 301. The upper chamber 303 is installed inside the exhaust pipe 301. The lower chamber 304 is installed inside the exhaust pipe 301. The one-way membrane tube 305 is installed at the top of the exhaust pipe 301.

[0032] The exhaust pipe 301 is fixedly connected to the upper surface of the connecting pipe 201, and the exhaust pipe 301 is fixedly connected to the lower surface of the connecting pipe 203.

[0033] The upper cavity 303 is located at the top of the filter screen 302, and the lower cavity 304 is located at the bottom of the filter screen 302.

[0034] The one-way membrane tube 305 is located on one side of the connecting tube 203 and at the bottom of the locking buckle 202.

[0035] The inside of the second latch 2 is provided with a second connecting pipe 201, the top of the second connecting pipe 201 is provided with a first connecting pipe 203, and the outer surface of the first connecting pipe 203 is provided with a first latch 202.

[0036] Connecting tube 1 203 is located on one side of the drug delivery head 103, and connecting tube 2 201 is located on one side of the infusion tube 2 104.

[0037] Further explanation is needed: The filter 302 installed inside the exhaust pipe 301 has the function of filtering blood membranes and blood bubbles. During normal blood transfusion, both latch 2 and latch 1 202 are in the open state. When expelling air, first close latch 2 and then close latch 1 202. At this time, press the exhaust pipe 301 so that the air inside the exhaust pipe 301 is expelled from the one-way membrane tube 305. At this time, the exhaust pipe 301 is in a negative pressure state. Then open latch 1 202 so that the blood inside the transfusion tube 101 and the connecting tube 1 203 enters the exhaust pipe 301. Finally, open latch 2. If the air inside the transfusion tube 101 and the connecting tube 1 203 is not completely expelled in one go, you need to close latch 1 202 before opening latch 2 and squeeze the exhaust pipe 301 again until the air is completely expelled.

[0038] Working principle: When a blood transfusion set with an exhaust port is used, a transfusion tube 101 is first set on one side of the insertion needle 1. The transfusion tube 101 is connected to the drug dispensing head 103. At the bottom of the drug dispensing head 103, it is connected to the transfusion tube 204 through connecting tube 1 203 and connecting tube 2 201. An exhaust mechanism 3 is set between connecting tube 1 203 and connecting tube 2 201. The exhaust mechanism 3 facilitates the discharge of air generated inside the transfusion tube 101 during blood transfusion.

[0039] When it is necessary to expel air from inside transfusion tube 101, during normal blood transfusion, both latch 2 and latch 202 are in the open state. To expel air, first close latch 2, then close latch 202. At this time, press the exhaust pipe 301 to allow the air inside the exhaust pipe 301 to be expelled from the one-way membrane tube 305. At this time, the exhaust pipe 301 is under negative pressure. Then open latch 202 to allow the blood inside transfusion tube 101 and connecting tube 203 to enter the exhaust pipe 301. Finally, open latch 2. If the air inside transfusion tube 101 and connecting tube 203 is not completely expelled in one go, close latch 202 before opening latch 2, and squeeze the exhaust pipe 301 again until the air is completely expelled. This device facilitates the expulsion of air from inside transfusion tube 101.
