Description
Technical Field
The utility model belongs to the medical treatment field especially relates to a blood filter blood filtration waste liquid bag that can empty fast.
Background
Continuous blood purification (cbp), also known as Continuous Renal Replacement Therapy (CRRT), is an important treatment and support means for critically ill patients, and has been widely used for various diseases such as acute renal insufficiency, severe pancreatitis, severe infection, refractory heart failure, etc. The hemofilter simulates glomerular filtration and renal tubule reabsorption, and ultrafilters water in blood while replenishing replacement liquid, maintains acid-base balance of patient's body and eliminates harmful matter. The specific method is that the blood of a patient is introduced into a semi-membrane filter which has good permeability and is equivalent to the area of a glomerular filtration membrane, when the blood flows through the filter, the water and most of the molecular substances in the blood plasma are filtered out except the proteins, cells and other visible components, so as to achieve the treatment purpose of removing the excessive water and solute remained in the blood. The currently used prism Flex hemofilter adopts a waste liquid dumping method in a hemofilter bag: when the machine alarms that the waste liquid is full, the blood filter bag is taken down, the waste liquid is poured, the blood filter bag is installed, and the machine continues to work.
The blood filter matching pipeline of the blood purifying and filtering instrument (blood filter) is only provided with a special waste liquid bag. In the blood purification process, the waste liquid bag is mainly used for collecting waste liquid filtered from the blood of a patient in the blood purification process, wherein the waste liquid comprises water and toxic metabolites in the blood, and the waste liquid is equivalent to kidney excrement (urine) of a normal human body. Such waste liquids are clinically referred to as controlled volume waste liquids.
The waste liquid in the hemofiltration waste liquid needs to be poured by a clinical nurse at regular time in the working process of the hemofiltration machine, and the waste liquid bag is installed on the hemofiltration machine again. The capacity of a common waste liquid bag is 3L, and clinical nurses always have very serious technical defects in the process of emptying the waste liquid bag:
one is slow pouring speed. The opening of the existing waste liquid bag is small, and the diameter of the pipe orifice is only about 3 cm. The clinical nurse needs to wait for the waste liquid to slowly flow out of the reserved small pipeline. The time of clinical nurses is required to be 6-8 minutes for completely emptying the waste liquid bag, and the nurses reinstall the emptied waste liquid bag into the hemodiafiltration machine, so that the working efficiency of the clinical nurses is seriously influenced. The method is not beneficial to the effective utilization of manpower, increases the workload of nurses, and makes statistics on the psychological and physiological stress state caused by serious fatigue strength due to the severe fatigue strength caused by the high-strength working pressure of hemofilter nurses in 2015, 11, 22, 33 < China contemporary medicine-nursing research >;
secondly, potential safety hazards exist. The waste liquid in the waste liquid bag needs to be specially treated, a nurse needs to leave a ward to dump the waste liquid to a sewage treatment room, and in a time space of leaving the ward, a critically ill patient is separated from monitoring, so that potential safety hazards exist;
thirdly, during the waste liquid dumping, the hemofilter is in a low-speed running state, and the dehydration effect of a patient in unit hour is influenced. For example, the dehydration amount is set to 200 ml under the normal operation condition of the hemofilter, namely the dehydration amount per hour of a patient is 200 ml when waste liquid is not poured; when the waste liquid needs to be poured, the hemofilter does not generate the waste liquid when in a low-speed running state, and the dehydration amount of a patient in a unit hour is only 110 milliliters. The time that the patient is wasted because of empting the waste liquid and actual dehydration volume are the inverse ratio, and the longer the time, the less the patient actually dehydrates, has seriously influenced patient's blood and has strained treatment effect.
Fourthly, the treatment cost of the patient is increased. If the number of waste liquid bags is increased, the blood filter manufacturer will increase the material cost of blood filter treatment of patients, and the running time of the blood filter machine at low speed is too long due to too long waste liquid pouring time, so that the blood filter time of the patients can only be increased to achieve the target dehydration amount. Hemofiltration therapy is charged hourly, virtually increasing the economic burden on the patient of 100-.
The blood filtering waste liquid bag of the blood filter has the defect of being unobtrusive, thereby not only increasing the operation difficulty and occupational exposure for clinical nurses, but also increasing the treatment cost for treating patients and influencing the treatment effect. Therefore, there is a need to develop a device capable of rapidly emptying the waste liquid in the blood filtration waste liquid bag to improve the therapeutic effect and embody the humanistic care purpose of modern medical treatment.
SUMMERY OF THE UTILITY MODEL
The utility model relates to an overcome not enough among the prior art, provide a blood filter blood filtration waste liquid bag that can empty fast, can empty the waste liquid of blood filtration waste liquid bag fast, ensure the treatment of patient's blood filtration.
The utility model discloses a realize above-mentioned purpose, realize through following technical scheme, a waste liquid bag is strained to blood filter blood that can empty fast, including blood waste liquid bag body, characterized by: the blood filtering waste liquid bag is characterized in that a zipper type self-sealing opening is formed in the upper end opening of the blood filtering waste liquid bag body, a liquid inlet pipe communicated with the blood filtering waste liquid bag body is fixedly connected to the lower side of the zipper type self-sealing opening, and the liquid inlet pipe is sealed through a clamp.
