Referring to fig. 1-2, the present invention provides a technical solution:

a heating device for liquid before entering blood vessel is shown in figure 1, and comprises a first heating member 1, and a second heating member 2 is arranged on the first heating member 1.

In this embodiment, first heating member 1 and second heating member 2 all adopt the rigid plastic material to can realize that first heating member 1 and second heating member 2 carry out the fixed effect of centre gripping to returning the blood vessel.

As shown in fig. 2, close welding has two archs 11 on the first heating member 1, jack 111 has been seted up to the inboard of arch 11, all seted up recess 12 on first heating member 1 and the second heating member 2, draw-in groove 121 has all been seted up on the both sides cell wall of recess 12, the internally mounted of recess 12 has a plurality of heater strip 122, heater strip 122 passes through the wire and is connected with external power supply, arc wall 13 has all been seted up at the both ends of first heating member 1 and second heating member 2, all bond on arc wall 13 and have shell fragment 14, all bond on first heating member 1 and the second heating member 2 and have magnet piece 15, it has baffle 16 to closely bond in the recess 12, it has cover 161 to closely bond on baffle 16, be equipped with water bag 17 on baffle 16, the both sides of water bag 17 closely bond and have calorie strip 171, close welding has the protruding pole 21 of two position symmetries on the second heating member 2, protruding pole 21 is pegged graft in jack 111.

In this embodiment, the central point of shell fragment 14 is the arc to when returning the blood vessel card in two arc walls 13, the blood return pipe hugs closely with the arc segment in shell fragment 14, according to the elasticity of shell fragment 14 self, thereby can realize carrying out spacing fixed effect to the blood return pipe.

In this embodiment, the two magnet pieces 15 are positioned to correspond to each other, so that when the first heating member 1 and the second heating member 2 are fastened to each other, the two magnet pieces 15 achieve the effect of connecting the first heating member 1 and the second heating member 2 together due to the attraction of each other.

In this embodiment, the partition 16 is arc-shaped and has a gap with the bottom wall of the groove 12, and the heating wire 122 is located in the gap between the partition 16 and the bottom wall of the groove 12, so as to avoid the mutual contact between the heating wire 122 and the walls of the groove 12 and the partition 16.

In this embodiment, the thickness of the water bag 17 is smaller than the distance between the partition 16 and the opening of the groove 12, so that the situation that the first heating member 1 and the second heating member 2 cannot be completely clamped together due to the thickness of the two water bags 17 when the first heating member 1 and the second heating member 2 are clamped together with each other can be avoided.

In this embodiment, the clamping strip 171 is clamped into the clamping groove 121 and tightly adhered to the groove wall of the clamping groove 121, so that the water bag 17 is limited and fixed.

In this embodiment, the two ends of the torsion spring 22 are respectively and tightly bonded with the protruding rod 21 and the hole wall of the insertion hole 111, so that the effect of resetting the second heating member 2 which can rotate on the first heating member 1 is realized.

When the heating device before liquid enters the blood vessel in the embodiment, firstly, the first heating member 1 and the second heating member 2 are broken off, at the moment, the torsion spring 22 is distorted and deformed, then the blood return tube is placed between the first heating member 1 and the second heating member 2 corresponding to the arc-shaped groove 13, then the second heating member 2 is turned over to be clamped on the first heating member 1, at the moment, the second heating member 2 is fixed on the first heating member 1 due to mutual attraction between the two magnet sheets 15 and the torsion of the torsion spring 22, and when the first heating member 1 and the second heating member 2 are mutually fastened together, the elastic sheets 14 in the arc-shaped groove 13 are mutually extruded to clamp and fix the blood return tube, then the heating wire 122 is mutually communicated with an external power supply and starts to work, the heating wire 122 is electrified to generate heat, so that the water bag 17 can be heated, because of the water bag 17, the blood return tube between the two water bags 17 is indirectly heated, finally, the effect of heating the liquid in the blood return pipe is achieved.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
