Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and more specifically, particularly relates to a plastic blood bag for preventing blood leakage. Background Art
[0002] A disposable plastic blood bag is used to store the blood of unpaid blood donors. The blood bag is generally provided with an outlet tube, that is, a blood transfusion socket. Clinical medical staff insert a puncture needle of a blood transfusion device into the outlet tube to deliver the blood into the body of a patient in need of blood transfusion.
[0003] Based on the above, the inventor found the following problems: When the blood storage bag is picked up by hand due to gravity, it often tilts to one side and is uneven; when in an emergency rescue for a car accident injury and blood transfusion is needed, if the medical staff operate improperly, it is easy to cause the puncture needle of the blood transfusion device to pierce the bag body near the outlet tube of the disposable plastic blood bag, resulting in a series of safety hazards such as blood outflow and blood contamination; this may lead to the patient not being able to receive blood transfusion in time, affecting the treatment. In today's society, blood resources are very scarce, and wasting and discarding blood due to work mistakes is a very serious medical malpractice.
[0004] When pulling out the puncture needle of the blood transfusion device from the outlet tube of the blood bag after blood transfusion, the residual blood in the bag body sometimes leaks out, dripping onto the hospital gown or the ground beside the bed, etc., polluting the environment and causing the patient and their family members to worry about the medical staff's unqualified operation skills during the treatment.
[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a plastic blood bag for preventing blood leakage is provided, in order to achieve a more practical value. Content of the Utility Model
[0006] In order to solve the above technical problems, the utility model provides a plastic blood bag for preventing blood leakage to solve the problem that the puncture needle of the current blood transfusion device pierces the bag body near the outlet tube of the disposable plastic blood bag and blood flows out.
[0007] The purpose and effect of the plastic blood bag for preventing blood leakage of the utility model are achieved by the following specific technical means:
[0008] A plastic blood bag for preventing blood leakage includes a blood bag and an outlet tube. A first plastic sleeve and a second plastic sleeve are arranged on the blood bag below the outlet tube. The first plastic sleeve and the second plastic sleeve are movably connected by a central column. An upper inner part of one end of the first plastic sleeve is provided with a first mounting sleeve, and a lower inner part of one end of the second plastic sleeve is provided with a second mounting sleeve. The first mounting sleeve and the second mounting sleeve are connected by a torsion spring.
[0009] Furthermore, the inner sides of the first plastic ferrule and the second plastic ferrule are respectively adhered to the two sides of the blood bag, and the torsion spring is located on the outer side of the central column.
[0010] Furthermore, a fastening sleeve is provided on the liquid outlet pipe, the fastening sleeve is annular, and a connecting piece is installed at one end of the fastening sleeve, and the two connecting pieces are connected by a clamping piece.
[0011] Furthermore, the two connecting members are provided with notches, which extend from one side of the connecting member to the connection with the two ends of the fastening sleeve, and the notches are arranged obliquely.
[0012] Furthermore, a V-shaped groove is provided on the inner side of the clamp, and limiting buckles are installed inside the V-shaped groove at both ends of the inner side of the clamp, and a limiting hole is provided on the inner side of the groove. The size of the limiting hole is adapted to the size of the limiting buckle, and the limiting buckle is located on the inner side of the limiting hole.
[0013] Furthermore, the elastic part of the clamping part has toggling blocks installed on both ends of the outer side of the clamping part.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] In the utility model, the first plastic ferrule and the second plastic ferrule are separated in a V shape with the central column as the center. The first mounting sleeve drives the torsion spring to move, and the torsion spring is deformed. The first plastic ferrule and the second plastic ferrule are placed on the side of the blood transfusion needle inside the blood bag. The first plastic ferrule and the second plastic ferrule are loosened. Through the action of the torsion spring, the first plastic ferrule and the second plastic ferrule can be tightly attached to the blood bag, thereby protecting the blood bag part and effectively preventing the needle from penetrating the blood bag.
[0016] In the utility model, the card is pushed so that the card gradually enters the inner side of the slot. The slot is set obliquely, so the card can be gradually expanded. By continuously pushing the card, when the limit buckle on the inner side of the card moves to correspond to the limit hole, the limit buckle can enter the inside of the limit hole through the elasticity of the card itself, and fix the two ends of the fastening sleeve. After the needle is pulled out, the fastening sleeve is clamped to the liquid outlet tube at the same time, which can effectively prevent liquid leakage. BRIEF DESCRIPTION OF THE DRAWINGS
