Description
Technical Field
The invention relates to a medical appliance, in particular to a blood collection bag.
Background
The blood drawing bag is a common blood drawing device, and is widely applied due to low cost, convenient use and no cross contamination of blood; in the blood sampling process, medical personnel often require a blood sampler to periodically grip and relax a fist so as to facilitate blood vessel expansion and promote blood outflow; because animals are different from human beings, the animals cannot cooperate with blood sampling operation of medical staff in the blood sampling process, so the blood sampling speed is low, the time cost is long, and meanwhile, the blood sampling operation becomes abnormally difficult along with struggle of the animals; also causes a long time of suffering to the animals; in addition, for patients with low internal blood pressure, such as weak women and the elderly, the blood flow speed is slow, and too much time is consumed in the blood drawing process, which undoubtedly brings great resistance to blood drawing.
Disclosure of Invention
In order to solve the problems, the invention provides a power-assisted blood collection bag which is novel and unique in structure, can effectively improve the blood collection speed, accelerate the medical process and reduce the pain time and psychological pressure of patients on the premise of ensuring the blood collection cleanliness.
In order to solve the problems, the technical scheme adopted by the invention is as follows: the power-assisted blood collection bag comprises a bag body, wherein a standby tube and a blood collection tube are arranged on the bag body, and a blood collection needle is arranged at the end part of the blood collection tube;
a booster is connected in series between the blood collection tube and the blood collection needle;
the booster comprises a booster cavity, a driving cylinder is movably arranged on the booster cavity, and two ends of the driving cylinder penetrate through the cavity wall of the booster cavity; the driving cylinder can freely rotate around the axis of the driving cylinder, and the driving cylinder and the power-assisted cavity are kept in a liquid seal state in the rotating process;
the outer cylinder wall of the driving cylinder is provided with a power-assisted wind wheel; a driving rod is arranged on the axis of the driving cylinder, and the driving rod is connected with the driving cylinder through a one-way bearing; the outer wheel of the one-way bearing is fixedly connected with the inner cylinder wall of the driving cylinder, and the inner wheel of the one-way bearing is combined with the driving rod through threads; a limiting plate and a driving plate are fixed at two ends of the driving rod, and a reset pressure spring is arranged between the driving plate and the power assisting cavity.
The invention has the beneficial effects that: during blood collection, after the blood taking needle punctures a blood vessel, the bag body and the blood taking needle are fixed; blood flows through the boosting cavity and the blood collection tube from the blood collection needle and then enters the blood bag; in order to improve the blood drawing efficiency, the medical staff periodically presses the driving plate to enable the driving rod to reciprocate on the axis of the driving cylinder; the driving rod drives the one-way bearing to rotate directionally through transmission of a thread structure, so that the driving cylinder and the power-assisted wind wheel are driven to rotate directionally; the boosting wind wheel rotates in the boosting cavity and presses the blood in the boosting cavity to the blood collection tube from the blood collection needle, so that the blood drawing speed is improved; along with the pressing of drive plate, blood can accelerate the outflow, effectively improves the speed of drawing blood, shortens the time of drawing blood.
In addition, in the blood drawing process, the blood is stirred and pretreated by the power-assisted wind wheel, so that the blood is effectively prevented from coagulating, and the preliminary separation of the blood can be promoted; providing convenience for the next blood treatment.
In conclusion, the blood sampling device is simple in structure and convenient to operate, and can effectively improve the blood sampling speed and shorten the blood sampling time; for the crowd afraid of blood, the fear time and the pain time of the crowd can be effectively shortened, the blood sampling is facilitated, and the working efficiency of medical personnel is also improved.
Preferably, a stopper is arranged on the blood collection tube, and the stopper is positioned between the bag body and the boosting cavity; under the condition that the blood needs to be processed in time, the blood sampling tube can be blocked by using a stopper, the driving plate is extruded for multiple times, the blood is fully stirred and processed, and the stopper is opened after the blood reaches the pretreatment standard; in addition, the cut-off device can also be used for blood sampling, and the blood in the bag body is effectively prevented from being polluted.
Preferably, a blood type indicating ring is arranged on the outer cylinder surface of the driving cylinder; when blood flows through the blood type indicating ring, the corresponding blood type indicating ring can display the blood type of carrying blood to carry out audio-visual suggestion to medical personnel, prevent that medical personnel from getting wrong blood type.
