Problems solved by technology

Due to the physiological characteristics of platelets that are easy to aggregate, in order to avoid platelet aggregation during clinical transfusion, nurses generally use regular inspections. Once the platelets in the blood bag are found to be aggregated or have a tendency to aggregate, the blood bag needs to be shaken manually; The shaking strength of personnel is different, and the appropriate oscillation frequency and amplitude cannot be guaranteed, which may easily cause uneven oscillation of platelets and increase the risk of platelet aggregation. In addition, the work intensity of nursing staff is high; therefore, there is an urgent need for a medical anticoagulation device for platelet transfusion

Embodiment 1

[0022] Such as figure 1 As shown, a medical platelet transfusion anticoagulation device includes: a bracket 1, an outer tube 2, an inner tube 3, and an anticoagulation component; the outer tube 2 is arranged on the upper side of the bracket 1, and the outer tube 2 and the bracket 1 connection; the inner tube 3 is set inside the outer tube 2 and coaxial with it, and the inner tube 3 is connected to the outer tube 2 in rotation; the platelet bag can be rotated and shaken by the rotating ring formed by the outer tube and the inner tube; anticoagulation The assembly is arranged on the inner tube 3, and is used to prevent platelet aggregation inside the platelet bag by shaking the platelet bag; the anticoagulation assembly includes: two U-shaped splints 4, which are symmetrically arranged at the bottom of the inner tube 3, and the two Two U-shaped splints 4 are respectively movably connected with the inner wall of the inner tube 3 to form an annular clamp; the hook 5 is arranged on...

Embodiment 2

[0027]In order to further improve the safety of platelet transfusion, the first double output end motor of the driving mechanism and the ring tooth arc are used together to precisely control the frequency of inner tube rotation, ensure the frequency and amplitude of platelet bag shaking, and effectively avoid the occurrence of platelets. gather.

[0028] Such as image 3 , 4 As shown, preferably, the drive mechanism includes an annular sinker 21 provided on the side of the inner tube 3 close to the outer tube 2, an annular connector 22 is fixed on the inner wall of the outer tube 2, and the annular connector 22 is embedded in the annular sinker 21 and connected with it, the inner pipe 3 is located in the annular sinker 21 and is provided with a through hole 23 on the side away from the outer pipe 2, the inner side of the through hole 23 is provided with a mounting plate 24, the mounting plate 24 is fixedly connected with the inner pipe 3, installed The plate 24 is fixedly pr...

Embodiment 3

[0030] In order to further improve the convenience of platelet transfusion, through the two toggle wheels formed by the rotating shaft above the motor side of the first double output end and the lever, it can be toggled on both sides of the platelet bag. It can make the platelets flow up and down, and can re-disperse the platelets that have just aggregated or have the tendency to aggregate, so as to avoid the aggregation of platelets and also prevent the blood bag from clogging.

[0031] Such as figure 2 As shown, preferably, the toggling mechanism includes two rotating shafts 31 symmetrically arranged above the two sides of the first double output end motor 25 and parallel to the output shafts. Two driving rods 32 are arranged symmetrically on the side, and a connecting rod 33 is arranged between the two driving rods 32. The connecting rod 33 passes through the rotating shaft 31 and is fixedly connected thereto. The two ends of the connecting rod 33 are perpendicular to the ...

Abstract

The invention relates to medical platelet infusion anti-coagulation equipment, and belongs to the technical field of blood transfusion equipment. The platelet bag comprises a support, an outer tube arranged on the upper side of the support, an inner tube arranged in the outer tube in a penetrating mode and coaxial with the outer tube, and an anti-coagulation assembly arranged on the inner tube and used for preventing platelet aggregation in the platelet bag by shaking the platelet bag. The anti-condensation assembly comprises two U-shaped clamping plates symmetrically arranged at the bottom of the inner pipe and a hook arranged at the top of the outer pipe. The platelet bag can be rotated and shaken through the rotating ring formed by the outer tube and the inner tube, and the platelet bag can be fixed by matching the rotating ring with the U-shaped clamping piece and the hook, so that the shaking stability is improved, and the shaking frequency and amplitude are ensured to be optimal; the risk of platelet aggregation and platelet damage caused by human factors in the clinical platelet infusion process is reduced, and the safety of platelet infusion is ensured; the anti-condensation equipment is convenient to use, easy to operate, high in practicability and worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of blood transfusion equipment, in particular to a medical platelet transfusion anticoagulation equipment. Background technique [0002] Platelet transfusion is suitable for the treatment and prevention of bleeding caused by platelet count reduction or functional defect, so as to restore and maintain the normal hemostasis and coagulation function of the body. As an important part of component blood transfusion, it plays an irreplaceable role in clinical treatment and rescue of patients role. Due to the physiological characteristics of platelets that are easy to aggregate, in order to avoid platelet aggregation during clinical transfusion, nurses generally use regular inspections. Once the platelets in the blood bag are found to be aggregated or have a tendency to aggregate, the blood bag needs to be shaken manually; The shaking strength of personnel is different, and the appropriate oscillation frequency an...
