Description

A kind of monitoring of automatic cytological preparation venous transfusion bag cell concentration and evenly mixing device

Technical field

The utility model relates to the field of medical instrument technology, in particular to a kind of automatic cytological preparation venous transfusion bag is thin Born of the same parents' concentration monitor and evenly mixing device.

Background technique

Cell therapy the Fashion of Future Medical Revolution, cell therapy refer to the human body cell that normal or bioengineering was transformed Patient's body is inputted, the cell newly inputted can supplement, substitute damaged cell, or have the function of stronger immunologic cytotoxicity, from And achievees the purpose that alleviate symptom or treat disease.Cell therapy is alleviating shock and treatment wound, cancer, blood disease, painstaking effort Pipe disease, diabetes, senile dementia etc. show higher and higher application value.Using cell preparation as medicine Object is one of future clinical developing direction.It is normal to divide, cell therapy include find and be widely used very early it is defeated Blood, in addition to this, novel tumor cellular immunotherapy and stem-cell therapy are also gradually applied to clinic.

The blood product that clinic is often transfused includes: Red Blood Cells Concentrate, red cell suspension and Platelet Concentrate etc..Cell Immunization therapy is a kind of emerging tumor treatment model, it acquires immunocyte from the patient, then carry out in vitro culture and Amplification, then feeds back in patient body, Lai Jifa and the autoimmune function for enhancing body to treat tumour, mainly include CIK, A few major class immunocytes such as DC, NK.Stem cell is the initial cell with self-replacation and multi-lineage potential, is rising for body Source cell is the initial cell to form the various histoorgans of human body.Under certain condition, it can be divided into multiple functions cell Or histoorgan, medical field are called " general-purpose cell ".Stem-cell therapy be health stem cell transplantation to patient or oneself In vivo, to achieve the purpose that repair sick cell or the normal cell of Reconstruction of The Function and tissue.

Existing clinical application status and deficiency:

1, whole blood or red blood cell are clinically inputted now: the coarseer venipuncture of selection；It is needed before infusion by blood bag hand It is dynamic to overturn for several times repeatedly, be sufficiently mixed red blood cell with additive, when necessary in infusion process manual jog blood bag make it is red carefully Born of the same parents are hanged,, can be by a small amount of 0.9% sodium chloride injection if it is unsmooth drop speed occurred to avoid there is more more defeated slower phenomenon It is injected in blood bag by Y-piece (double-end blood transfusion apparatus) and is diluted and mixed, 0.9% chloride injection can be used when blood is finished Liquid rinses blood bag, and diluting cells suspension washes away the cell of adhesion, and does not waste the remaining blood in blood bag as far as possible；It strictly grasps defeated It infuses the time, fast after first slow, Infusion Time is usually no more than 4h；Washed Red Blood Cells should be transfused as early as possible, it is necessary to be finished in 2h, as because Therefore fail to be transfused in time, it can only be saved for 24 hours in 4 DEG C of refrigerators；Any drug cannot be added in red blood cell, solidification otherwise can occur, coagulate Collection or haemolysis；

2, input blood platelet: preservation condition is 24~26 DEG C, checks platelet-free clustering phenomena before being transfused, gently vibrates； Decline because of extension of the platelet function with the holding time, so should be transfused immediately after fetching (blood bag is mixed before infusion, is cut Avoid and be aggressively shaken, to prevent platelet injury), 80-100 drop/point, or with the patient rate infusion of patient, in infusion process The manual jog blood bag of medical worker hangs blood platelet, 1 part the therapeutic dose platelet transfusion time < 20 minutes, and infusion process Middle nurse must not leave, and forbid for a long time resting on blood platelet on table top, avoid being aggregated；

3, input the immunocytes such as CIK cell: multi-pass is crossed transfusion bags and is fed back, and the drip velocity in returning step has Strict requirements usually require that preceding 15 minutes drip velocities are 30 drops/minute, and it is 45 that 15-30 minutes drip velocities, which can increase, Drop/minute, if drop speed can be gradually increased without discomfort in patient, not more than 70 drops/minute are finished in 1 hour.In order to prevent CIK cell blocking feeds back the lumen of bag or sticks tube wall, and every 5-10 minutes needs shake gently during CIK cell feeds back instillation Feed back bag, cell settlement avoided to accumulate, keep infusion unobstructed, until drip off, after infusion again with normal saline flushing feed back bag and Pipeline avoids the immunocyte in waste preparation.Can be advised in returning step family members or nurse shaked gently every 5-10 minutes or It squeezes and feeds back bag bottom, sedimentation cell is made to suspend again；

4, stem cell is inputted: the coarseer venipuncture of selection；It needs manually to overturn blood bag for several times repeatedly before infusion, make Stem cell is sufficiently mixed with additive, and overturning infusion bag manually in infusion process hangs stem cell, more defeated to avoid occurring The slower and agglomerating phenomenon of cell；

Cell feedback is the very important link of cell therapy, these cell products are in the preparation often by cell at present It is suspended in the cell feedback bag for filling physiological saline or annex solution, but has two big difficulties in use, first is that due to thin Born of the same parents' specific gravity is larger, and cell is easy for being deposited in the lower part of infusion bag after being transfused a period of time, causes solution viscosity excessive, occurs More more defeated, slower phenomenon；In addition, because cell biological nature, feed back suspension in cell be easy to stick it is agglomerating, if filtering Will lead to the cell fed back in bag cannot feed back completely to patient, cause cell to waste, but if do not use filtration system, very To blocking blood vessel is possible to, patient is made to cause danger.

Present clinically application cell product, by overturning solution bag or gently shaking for several times repeatedly, keeps cell mixed before transporting to It is even to be transfused.Also to gently shake solution bag frequently in infusion process when necessary mixes cell, if having there is drop speed not Freely, then on the basis of mixing gently, physiological saline is added and is diluted and is mixed.The method has very big drawback, is logical first Cross medical worker's subjective judgement, it may be found that when to have resulted in cell settlement excessive or agglomerating；Secondly, not only waste of manpower, and And may be because the negligence of family members or nurse, forget aforesaid operations, result in blockage, cause to be infused unsmooth, wastes cell；Most Afterwards, the amplitude shaken manually is not easy to control, and dynamics cannot gentlier reach mixing purpose, and the excessive cellular damage that may cause of dynamics is broken It bursts, influences therapeutic effect.

Existing research disadvantage:

Firstly, existing study the not intelligent apparatus about concentration monitor automatic in infusion vessel during cell infusion. In addition, entitled " a kind of cell feedback Special Automatic pendulous device of bag " and the patent No. of existing patent No. CN201420862102.X The utility model of entitled " cell feeds back liquid evenly mixing device " of CN201521030159.4, two kinds of utility models are using pendulum respectively The method that dynamic or vibration feeds back bag mixes cell preparation, and preferred application range is immune cell therapy and stem-cell therapy, ignores The most wide blood product of clinical application range is transfused problem at this stage；Secondly intelligent cell concentration does not monitor system, carefully The concentration of born of the same parents' preparation is not sufficiently stable, to influence the process and final therapeutic effect of infusion.
