Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Please refer to fig. 1-3, in the embodiment of the present invention, an anti-prick immune cell extraction blood transfusion bag comprises a blood transfusion bag body 1 and an anti-puncture mechanism, a hanging ring 14 is fixedly connected to the upper end of the blood transfusion bag body 1 for hanging the blood transfusion bag body 1, a pressure balance tube 15 for balancing the internal pressure of the blood transfusion bag body 1 is fixedly installed at the lower end of the blood transfusion bag body 1, a fixing tube 2 is fixedly connected to the lower end of the blood transfusion bag body 1, a first connecting tube 3 is fixedly connected to the lower end of the fixing tube 2, a first handle 10 is fixedly connected to the side wall of the first connecting tube 3, a second connecting tube 5 is arranged at the lower end of the first connecting tube 3, a rubber block 6 for plugging the second connecting tube 5 is fixedly connected to the first connecting tube 3 and the second connecting tube 5 for separation, a second handle 8 is fixedly connected to the side wall of the second connecting tube 5 for rotating the second connecting tube 5 for breaking off the second connecting tube 4, a rubber block 6 for plugging the second handle 5 is sleeved on the lower end of the first handle 10 and a second handle 8, and a second handle 8 for plugging the fixing frame 9 for fixing the second handle 8.
The puncture-preventing mechanism is arranged inside the fixed tube 2, the first connecting tube 3 and the second connecting tube 5 and is used for preventing the syringe needle from puncturing the side wall of the blood transfusion bag body 1 and preventing medical personnel from separating the second connecting tube 5 from the first connecting tube 3 by mistake, so that the second connecting tube 5 can work normally.
Prevent that puncture mechanism includes steel pipe 11, steel pipe 11 sets up inside fixed pipe 2, first connecting pipe 3 and second connecting pipe 5, 11 lower extreme fixedly connected with guide housing 7 of steel pipe, the one end fixed connection that steel pipe 11 was kept away from to guide housing 7 is on block rubber 6, cover 13 is collected to 11 upper end fixedly connected with of steel pipe, fixedly connected with is used for preventing on the collection cover 13 lateral wall that 1 inside blood of blood transfusion bag body from flowing to the inside sealing ring 12 of first connecting pipe 3, sealing ring 12 hugs closely on fixed pipe 2 lateral walls.
The operating principle of the puncture-proof mechanism is that when medical personnel sucks the blood inside the blood transfusion bag body 1 through the injector, the needle head of the injector penetrates from the center of the rubber block 6, the needle head moves along the steel pipe 11, then the medical personnel can suck the blood inside the blood transfusion bag body 1 through the injector, when the medical personnel need to remove the second connecting pipe 5, the medical personnel can remove the clamping frame 9, then the second handle 8 is rotated, the second handle 8 drives the second connecting pipe 5 to rotate, the second connecting pipe 5 drives the loosening block 4 to rotate, so that the loosening block 4 is broken, then the medical personnel can move the second connecting pipe 5 out, the second connecting pipe 5 drives the guide cover 7 to move, the guide cover 7 drives the steel pipe 11, the collecting cover 13 and the sealing ring 12 to move out, when the medical personnel mistakenly separate the second connecting pipe 5 from the first connecting pipe 3, and the sealing ring 12 still stays inside the fixed pipe 2, the medical personnel can sleeve the clamping frame 9 on the side walls of the first handle 10 and the second handle 8 again, because the sealing ring 12 seals the inner wall of the fixed pipe 2, and the blood transfusion bag body inside the steel pipe 11 is not influenced.
The utility model discloses a blood transfusion bag, including blood transfusion bag body 1, prevent that the syringe needle from punctureing transfusion bag body 1 lateral wall, prevent that the syringe needle from utilizing steel pipe 11 to carry out spacing the blocking to the syringe needle, prevent that the syringe needle from punctureing transfusion bag body 1 lateral wall, avoid the inside blood leakage of transfusion bag body 1, avoid blood to produce the pollution, and utilize and collect cover 13 and sealing ring 12 to prevent that the inside blood of transfusion bag body 1 from flowing to inside first connecting pipe 3 and the second connecting pipe 5, avoid the needle to absorb the inside blood of first connecting pipe 3 and second connecting pipe 5, and then avoid blood extravagant, avoid medical personnel to miss second connecting pipe 5 and the separation of first connecting pipe 3 simultaneously, as long as sealing ring 12 and collection cover 13 still stop inside fixed pipe 2, still can carry out the absorption of blood through the syringe needle, improve the availability factor of blood transfusion bag, and convenient for user uses.
The utility model discloses a theory of operation is:
when medical personnel absorb the blood inside the blood transfusion bag body 1 through the syringe, the needle head of the syringe penetrates from the center position of the rubber block 6, the needle head moves along the steel tube 11, and then the medical personnel can absorb the blood inside the blood transfusion bag body 1 by using the syringe.
When medical personnel need demolish second connecting pipe 5, medical personnel will block frame 9 and get rid of, then rotate second handle 8, and second handle 8 drives second connecting pipe 5 and rotates, and second connecting pipe 5 drives pine and takes off piece 4 and rotate to make pine take off piece 4 cracked, then medical personnel shift out second connecting pipe 5, and second connecting pipe 5 drives guide housing 7 and removes, and guide housing 7 drives steel pipe 11, collects cover 13 and sealing ring 12 and shifts out.
When medical personnel mistake with the separation of second connecting pipe 5 with first connecting pipe 3, and sealing ring 12 still stops when fixed pipe 2 is inside, medical personnel can be once more with card frame 9 cover on first in command 10 and the 8 lateral walls of second in command, because sealing ring 12 seals fixed 2 inner walls of pipe to do not influence the syringe needle of 11 inside steel pipes and absorb the blood of transfusion bag body 1 inside.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
