Example 1

A kind of disposable blood transfusion bag sealing plug, in order to avoid blood flowing out when the used blood transfusion bag is placed, the inventors set a plug 2, as a preferred embodiment, as shown in Figure 1, Figure 2 and Figure 3, including The blood transfusion bag 1 and a plurality of blood transfusion ports 10 provided at the bottom end thereof are inserted into the blood transfusion port 10 with a plug plunger 2, and an annular groove 20 is provided on the outside near the bottom end of the plug plunger 2, and the outer side of the annular groove 20 is provided with a sealing partition. 21. The sealing partition 21 is inserted and matched with the blood transfusion port 10. The center of the top surface of the sealing partition 21 is provided with a sleeve hole 210, and the inner middle of the sleeve hole 210 is provided with a circular boss 211. The circular boss 211 and the annular groove 20 is snap-fitted, the top edge of the sealing partition 21 is provided with a conical surface 212, the bottom end of the sealing partition 21 is provided with a limiting platform 213, the bottom end surface of the plug 2 is provided with a pull ring 22, and the top of the plug 2 is provided with Blunt needle 23.

In this embodiment, the plug 2 is made of PP material into an integrally formed structure, which is light in weight, good in toughness and rigid in strength. The sealing partition 21 is made of silica gel, which has good flexibility and good sealing performance, and plays a very good role. The sealing function of the seal is played, and the arrangement of the tapered surface 212 makes the insertion of the sealing partition 21 into the blood transfusion port 10 easily and unobstructed.

Further, the plug plunger 2 is cylindrical and its outer diameter is larger than the inner diameter of the blood transfusion port 10. Since the blood transfusion bag 1 is made of plastic, it has a certain elasticity, so that the plug rod 2 is inserted into the blood transfusion port 10 tightly to prevent blood from flowing out.

Specifically, the inner diameter of the sleeve hole 210 is smaller than the outer diameter of the plug 2, so that the sealing partition 21 is tightly sleeved on the outside of the plug 2, and then the annular boss 211 is snap-fitted with the annular groove 20, so that the sealing partition 21 is sleeved It is tightly connected and will not be squeezed out when the plunger 2 is inserted into the blood transfusion port 10 . The outer diameter of the limiting platform 213 is larger than the outer diameter of the blood transfusion port 10 , which is beneficial to block the bottom end of the blood transfusion port 10 .

In addition, the pull ring 22 is in the form of a circular ring, which is convenient for fingers to be pulled through by force. The blunt needle 23 is in the shape of a semi-circle, which is convenient to insert into the blood transfusion port 10 without being punctured.

Example 2

As the second embodiment of the present invention, in order to protect the plug, the inventor has provided a needle cover 3. As a preferred embodiment, as shown in FIG. 4, the top of the plug 2 is covered with a needle cover 3. The top of the needle cover 3 is provided with a suction cup 30, and the suction cup 30 is in the shape of an inverted trumpet.

In this embodiment, the needle cover 3 is made of a silicone material to form an integral structure, which has good flexibility and good adsorption.

Further, the bottom end of the needle sleeve 3 is provided with a sleeve cavity 31, and the inner diameter of the sleeve cavity 31 is smaller than the outer diameter of the plug rod 2. Because the needle sleeve 3 has a certain elasticity, it can be tightly sleeved outside the plug rod 2, Avoid slipping.

Specifically, the suction cup 30 and the needle cover 3 are integrally formed. When the suction cup 30 is pressed against the smooth contact surface, the internal air can be eliminated to generate negative pressure, and the suction can be tightly absorbed, which is convenient for fingers to hook the pull ring 22 and pull it. Out of the plunger 2.

When the disposable blood transfusion bag of the present invention is closed and plugged in use, when the patient's blood transfusion bag 1 is completely transfused, the medical staff can hook all four fingers on the pull ring 22, bring it to the ward, and plug one of them into the ward. The column 2 touches the glass or tile wall, so that the suction cup 30 of the needle cover 3 is forced to fit on the glass or tile wall, and the internal air is discharged to generate negative pressure, so that the adsorption is stable. At this time, the plug column 2 is pulled out. Insert it into the blood transfusion port 10 of the blood transfusion bag 1 until the sealing partition 21 enters the blood transfusion port 10, so that the limiter 213 touches the outer end of the blood transfusion port 10, and plays a sealing role to prevent the residual blood from flowing out and polluting the environment when the blood transfusion bag 1 is placed. , the next blood transfusion bag 1 can be collected after it is plugged, so that the blood transfusion bag 1 can be well cleaned in a centralized manner.

The basic principles, main features and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Under the premise of the spirit and scope, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the claimed invention. The claimed scope of the present invention is defined by the appended claims and their equivalents.
