DETAILED DESCRIPTION

[0021] The following embodiments will further illustrate the utility model, but the utility model is not limited by the following embodiments.

[0022] As Figs. 1 to 4As shown, the embodiment provides a transfusion tube winding device, which comprises a wheel shell 1 and a wheel hub inner core 2. The wheel shell 1 is hollow inside, and the wheel hub inner core 2 is coaxially placed in the inner cavity of the wheel shell 1 and can rotate in the inner cavity of the wheel shell 1, thereby realizing the effect of rotating and winding the transfusion tube. Two sides of the wheel shell 1 are respectively provided with threading holes 103. In use, the transfusion tube is inserted into the wheel shell 1 from one of the threading holes 103 and then is threaded out from the other threading hole 103.

[0023] The wheel shell 1 comprises an upper shell 101 and a lower shell 102. One side of the upper shell 101 is connected with one side of the lower shell 102 through a hinge 105, and the other side of the upper shell 101 is detachably connected with the other side of the lower shell 102 through a buckle 104, thereby realizing the opening and closing effect of the wheel shell 1, facilitating disassembly and assembly, and being more convenient to use.

[0024] A bottom of the wheel hub inner core 2 is upwardly provided with a wire clamping groove 201 penetrating through two sides. The transfusion tube is clamped in the wire clamping groove 201 before winding, and the center of the wire clamping groove 201 serves as the center of rotation.

[0025] A through hole 106 is formed in a top of the wheel shell 1, and a bending strip 4 is arranged on the edge of the through hole 106 in the axial direction. The bending strip 4 is made of plastic material and is convenient to bend. A pin 401 is arranged at the bottom of the free end of the bending strip 4. A pin hole 202 is formed in the center of the top of the wheel hub inner core 2. The pin 401 is inserted into the pin hole 202 in correspondence. The pin 401 is in the shape of a flat strip, and the shape of the pin hole 202 matches the pin 401. After the pin 401 is inserted into the pin hole 202, the relative position of the wheel hub inner core 2 and the wheel shell 1 is fixed, the wheel hub inner core 2 is prevented from rotating, and the fixing effect is realized.

[0026] A handle 203 is arranged on the top of the wheel hub inner core 2, and the pin hole 202 is formed in the center of the handle 203. The handle 203 can be directly operated by hand through the through hole 106, and the pipe line can be operated without disassembling the wheel shell 1, so that the operation is more convenient.

[0027] A bandage 5 is arranged at the bottom of the wheel shell 1, and two belt buckles 3 are arranged at the bottom of the wheel shell 1. The bandage 5 is inserted into the belt buckles 3, and the two ends of the bandage 5 are detachably connected through magic tapes. The wheel shell 1 can be bound to the limbs of a patient through the bandage 5, thereby facilitating fixation.

[0028] The use method of the embodiment is as follows:

[0029] Firstly, the wheel hub inner core 2 is taken out of the wheel shell 1, the transfusion tube is clamped in the wire clamping groove 201, the wheel hub inner core 2 is rotated to wind the transfusion tube on the outer periphery of the wheel hub inner core 2, then the wheel hub inner core 2 is put into the wheel shell 1, the transfusion tube is threaded out from the two threading holes 103, and the upper shell 101 and the lower shell 102 are assembled.

[0030] The bending strip 4 can be plastically bent, and when the bending strip 4 is lifted, the handle 203 can be directly rotated by hand through the through hole 106, so that the wheel hub inner core 2 is rotated, and the rolling and unfolding of the infusion tube are performed without opening the wheel shell 1.

[0031] After the bending strip 4 is pressed down, the pin 401 on the bending strip 4 is inserted into the pin hole 202 of the wheel hub inner core 2, so that the wheel hub inner core 2 is fixed and cannot be rotated, and the surface of the rear wheel shell 1 is not protruded after the bending strip 4 is pressed down and bent, so that bumping is avoided.

[0032] Finally, the wheel shell 1 is fixed on the limbs of a patient by the binding belt 5.

[0033] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
