Description

Technical Field

[0001] The utility model belongs to the technical field of blood transfusion apparatuses, and in particular relates to a blood transfusion apparatus with a self-fixing structure. Background Art

[0002] With the improvement of modern medical technology, the research and development and application of medical auxiliary equipment are becoming more and more extensive. Among them, the research and development technology and use technology of blood transfusion devices used for continued blood transfusions for emergency patients are becoming more and more mature. A blood transfusion device is a device that can be used to transport blood in a blood bag into the patient's body. It generally includes a blood bag puncture needle, a blood transfusion line, a venous puncture needle and other components.

[0003] The existing blood transfusion device has no fixed structure on the blood transfusion line. During the use of the blood transfusion device, the blood transfusion line is prone to shaking. The shaking blood transfusion line will have a certain impact on the flow and delivery of blood. For this reason, we propose a blood transfusion device with a self-fixing structure. Utility Model Content

[0004] The utility model aims to provide a blood transfusion set with a self-fixing structure, so as to solve the problem in the above-mentioned background technology that the blood transfusion line of the existing blood transfusion set is not provided with a fixing structure, and the blood transfusion line is prone to shaking during the use of the blood transfusion set, and the shaking blood transfusion line will cause a certain influence on the flow and delivery of blood.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blood transfusion device with a self-fixing structure, comprising a blood transfusion device main body, a fixing mechanism being arranged on the outer surface of a blood transfusion blood path of the blood transfusion device main body, the fixing mechanism comprising a through-tube sleeved on the blood transfusion blood path of the blood transfusion device main body, a mounting seat 1 and a mounting seat 2 being fixedly mounted on the outer surface of the through-tube, two clamping plates being slidably mounted on the side surface of the mounting seat 1, a fixing seat and a clamping seat being fixedly mounted on the side surface of the mounting seat 2, a rotating shaft being rotatably mounted on the inner wall of the fixing seat, a winding rod being fixedly mounted on the outer surface of the rotating shaft, the winding rod being clamped on the inner wall of the clamping seat, a clamping rod being slidably mounted on the clamping seat at a position directly opposite to the winding rod, and a clamping hole for the clamping rod to be clamped into is provided on the surface of the winding rod.

[0006] By adopting the above scheme, a through-tube is provided to cooperate with the mounting seat 1 and the clamping plate. The two clamping plates are clamped on the surface of the infusion stand and the position is locked by fixing screws and nuts, so that the blood transfusion line can be stabilized, and the shaking of the blood transfusion line during the blood transfusion process can be avoided, which has a good stabilizing effect. By providing the mounting seat 2 to cooperate with the winding rod, the winding rod can be unlocked and rotated to unfold, and the excess length of the blood transfusion line can be wound and collected, and the winding rod can be rotated, closed and locked to achieve storage, so as to avoid the blood transfusion line being too long and placed arbitrarily, which is convenient for operation.

[0007] As a preferred embodiment, the upper surface and the lower surface of the through-tube are both fitted with limiting rings, and the limiting rings are fixed to the outer surface of the blood transfusion blood circuit of the blood transfusion device body.

[0008] By adopting the above solution, the setting of the limiting ring can limit the position of the penetrating tube, thereby preventing the penetrating tube from shaking and moving randomly on the surface of the blood transfusion line.

[0009] As a preferred embodiment, a trapezoidal slider is fixedly installed on the side of the positioning plate, a trapezoidal slide groove is opened on the side of the mounting seat for the trapezoidal slider to slide, and a spring 1 is fixedly installed on the inner wall of the trapezoidal slide groove, and the other end of the spring 1 is fixedly connected to the side of the trapezoidal slider.

[0010] By adopting the above scheme, the trapezoidal slider is used in conjunction with the trapezoidal slide groove, which can provide limit support for the movement of the locking plate, ensure the stability of the movement, and prevent the locking plate from separating from the mounting seat. When the two locking plates move away from each other, the spring 1 is in a deformed state, so the elasticity of the spring 1 can be used to achieve an initial fixing effect.

[0011] As a preferred embodiment, a fixing screw is fixedly installed on the upper surface of the trapezoidal sliding block, and a strip hole is opened on the upper surface of the mounting seat, which is opposite to the trapezoidal sliding groove and connected to the trapezoidal sliding groove, and the fixing screw passes through the strip hole and is threadedly installed with a nut.

[0012] By adopting the above solution, after the positioning plate is slid to adjust the position, the fixing screw is screwed on with the nut to achieve a squeezing and locking effect to prevent the position from loosening.

[0013] As a preferred implementation, the side surface of the positioning plate has an arc-shaped area, and an anti-slip pad is pasted in the arc-shaped area.

[0014] By adopting the above solution, the arc-shaped area is used together with the anti-skid pad, so that the whole can be stably fixed on the surface of the infusion stand to avoid slipping during fixation.

[0015] As a preferred implementation, an operating disk is fixedly mounted on the top end of the locking rod, and a second spring is fixedly mounted between the operating disk and the locking seat.

[0016] By adopting the above solution and utilizing the elasticity of the second spring, it can be ensured that the locking rod is quickly and stably locked into the locking hole, thereby realizing convenient locking of the winding rod.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The blood transfusion set with a self-fixing structure is used by arranging a through-tube to cooperate with a mounting seat and a clamping plate. The two clamping plates are clamped on the surface of the infusion stand and the position is locked by fixing screws and nuts, so that the blood transfusion line can be stabilized, and the shaking of the blood transfusion line during the blood transfusion process can be avoided, which has a good stabilizing effect.

[0019] The blood transfusion device with a self-fixing structure is used in conjunction with a winding rod by arranging a second mounting seat. When the winding rod is unlocked and rotated to unfold, the excess length of the blood transfusion tube can be wound and collected, and the winding rod can be rotated, closed and locked to achieve storage, thereby preventing the blood transfusion tube from being too long and placed arbitrarily, and facilitating operation.
