[0027] The transfusion device has the following advantages:

[0028] 1. The flow is regulated by rotating the upper adjusting part and the lower adjusting part to change the width of the flow channel, which has higher accuracy than the way of squeezing the hose.

[0029] 2. When the liquid is high in viscosity, the first connecting pipe can be used to input warm water, and the second connecting pipe can be used to discharge warm water, so that the upper connecting part and the lower connecting part are heated to prevent the liquid from solidifying and blocking the flow channel at low temperature.

[0030] In one embodiment, the upper adjusting member is provided with an upper adjusting hole 4-16, the fourth connecting pipe communicates with the upper adjusting hole, the lower adjusting member is provided with a lower adjusting hole 4-23, and the fifth connecting pipe communicates with the lower adjusting hole; the top surface of the lower adjusting member is provided with a strip-shaped groove 4-24 and an arc-shaped groove 4-25, one end of the strip-shaped groove corresponds to the upper adjusting hole, and the other end communicates with the lower adjusting hole; the arc-shaped groove is concentrically arranged with the second center hole, the width of the arc-shaped groove smoothly transitions from one end to the other end, one end of the arc-shaped groove is connected with the strip-shaped groove, and the connection position corresponds to the upper adjusting hole, and the width of the other end of the arc-shaped groove is zero. In use, by rotating the upper adjusting member or the lower adjusting member, the area corresponding to the upper adjusting hole and the arc-shaped groove changes, thereby changing the flow rate of the liquid flowing into the arc-shaped groove through the upper adjusting hole.

[0031] In one embodiment, the bottom surface of the upper adjusting member is inlaid with an elastic gasket 4-4, wherein the elastic gasket can be a rubber gasket or a silica gel gasket, the elastic gasket is provided with a through hole 4-41 communicating with the upper adjusting hole, the top surface of the elastic gasket is provided with a cannula 4-42 communicating with the through hole, the cannula is inserted into the upper adjusting hole, and the cannula is coaxially arranged with the through hole; a water storage groove 4-17 is arranged between the top surface of the elastic gasket and the upper adjusting member, and the water storage groove communicates with the first center hole. By arranging the elastic gasket, the lower surface of the upper connecting member and the upper surface of the lower connecting member are in close contact, which effectively prevents the liquid passing through the upper adjusting hole from overflowing to the outside of the arc-shaped groove and directly flowing into the strip-shaped groove, thereby affecting the accuracy of the flow regulator.

[0032] Embodiment 2 is a further improvement based on Embodiment 1, see Figure 4 , the water storage groove is provided with an electric heating element 4-5, the upper adjusting member is provided with a power supply connector 4-6 connected with the electric heating element, which can be a plug or a USB connector, etc., for the fourth connecting pipe to connect the water supply pipe, and the electric heating element is powered to heat the water in the water outlet groove. In addition, the fifth connecting pipe can also be threadedly connected with a plugging cap to block the fifth connecting pipe from below when the water outlet groove needs to store water.

[0033] As a preferred embodiment, the edge of the upper adjusting member extends upward to form an upper extension 4-18, and the edge of the lower adjusting member extends downward to form a lower extension 4-26, so that the upper extension and the lower extension are convenient for the user to hold during operation. In addition, the annular upper extension forms a shield for the first connecting pipe and the fourth connecting pipe, and the lower extension forms a shield for the third connecting pipe and the fifth connecting pipe. When the connecting pipes are connected with the corresponding pipelines, the connection position is not easy to be accidentally separated.

[0034] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent substitutions or changes within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
