Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to automatic medical blood irradiation equipment of continuous type.
Background
Transfusion-associated graft-versus-host disease (TA-GVHD) is a fatal complication of transfusion in which immunocompetent lymphocytes in transfused blood cannot be removed, transplanted in vivo, proliferated, identified as non-self substances in tissues and organs of a patient, and targeted for immune attack and destruction. The clinical manifestations of TA-GVHD lack specificity, and are easy to miss diagnosis and misdiagnose.
Irradiation of blood products prior to transfusion is currently considered to be the only effective way to prevent TA-GVHD. The blood irradiator is a medical device which uses rays to irradiate blood products, inactivates lymphocytes and prevents TA-GVHD diseases (transfusion-related graft-versus-host disease) in transfusion activities; the mechanism is as follows: lymphocytes are sensitive to radiation, and by irradiation with radiation of appropriate dose, immunocompetent lymphocytes can be inactivated and lose their proliferative capacity. But has little influence on the functions of red blood cells and platelets and the activity of blood coagulation factors.
From the ray source, the blood irradiator can be divided into two types, one is to irradiate the blood product with gamma rays generated by the radioactive source (mainly Cs-137 and Co-60), and the other is to irradiate the blood product with X rays generated by the X-ray tube.
Radioactive source type blood irradiator apparatuses require the assembly of several hundred to thousands of curie isotope radioactive sources, which presents a potential risk of nuclear leakage. The X-ray source type blood irradiator has no risk of nuclear leakage, but no radiation is generated when the apparatus is powered off.
In summary, the disadvantages of the prior art are as follows:
1) the existing X-ray blood irradiation instrument device adopts a blood cup as a container of a blood bag, such as CN206652034U, a plurality of blood bags are stacked after being placed in the blood cup, and the blood bags cannot be placed in the blood cup without air gaps, so that the difference between the actual irradiation dose of the blood bag in the blood cup and the dose in a theoretical state is too large. Even if the blood cup is placed without air gaps, the irradiation dose deviation of the blood bag in the blood cup is larger than 10%.
2) The existing irradiators can be used intermittently, namely, the equipment needs to be stopped after a sample finishes irradiation, and can be started again for irradiation after the sample is replaced, so that the working efficiency is low.
3) The existing national regulation blood bags are provided with codes, and the existing equipment is in work, the codes are not input or are input manually, so that the error probability is very high.

The platelets or fresh blood are mixed with lymphocytes, and the allogenic lymphocytes enter the body of a patient with low immunity to cause the occurrence of transfusion-related graft-versus-host disease (TA-GVHD), and the serious degree can cause the death of the patient. Irradiation of blood products prior to transfusion is currently considered to be the only effective way to prevent TA-GVHD. The mechanism is as follows: lymphocytes are sensitive to radiation, and by irradiation with radiation of appropriate dose, immunocompetent lymphocytes can be inactivated and lose their proliferative capacity. The radiation with proper dose has little influence on the functions of red blood cells and platelets and the activity of blood coagulation factors. Therefore, after sufficient radiation of platelets or fresh blood, lymphocytes with immunological activity in the blood can be effectively inactivated, thereby greatly reducing the incidence rate of GVHD and ensuring the safety of blood transfusion.
The X-ray spectrum consists of a continuous spectrum and a marking spectrum, the content of a low-energy part in the spectrum is more, and the low-energy part is easily absorbed by a large amount of superficial blood in the process of irradiating blood or blood products, so that the quantity of X photons reaching the deep part is rapidly reduced. The ray propagation of the X-ray source type blood irradiator follows the following formula
The radiation dose is therefore also inversely related to the square of the distance of the radiation source. In order to ensure the quantity of single irradiation, the existing equipment mostly adopts a cylinder mode and places most blood bags into a cylinder. This results in the radiation penetrating the blood in the cylinder to a great thickness, which makes the irradiation dose hard to meet the requirement of the blood irradiator standard for the uniformity of the radiation (the national standard requires the non-uniformity of the irradiation of the blood irradiator<20%). The blood bag is placed in the irradiation box and irradiated on the platform, so that the thickness of the blood bag in the vertical direction of rays is reduced, and the nonuniformity of actual blood irradiation in irradiation is far less than 20% specified by national standards.
Owing to adopted above-mentioned technical scheme, compare with prior art, the beneficial effects of the utility model are that:

The consistency of the irradiation dose of the blood bag of the system is good and far superior to the requirement of national regulation (20 percent).
