Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-Figure 5 An infusion heater shown in the figure comprises a shell 2 and a cover plate 1 detachably arranged on the shell 2, the cover plate 1 and the shell 2 both have heating cavities inside, and heating boxes 5 are arranged in the two heating cavities, the two heating boxes 5 have sides facing each other recessed inward to form arc grooves, notches for the infusion tube to pass through are provided on both sides of the cover plate 1 and the shell 2, and the two notches can be spliced ​​to form a circular opening, a temperature display is also provided on the cover plate 1, and temperature sensors are provided in the two heating cavities for detecting the temperature of the heating boxes 5 and displaying the temperature through the temperature display, and a valve nozzle for convenient water addition and drainage is provided on the heating box 5;

[0027] A tube clamping mechanism 4 is provided in both openings, and the tube clamping mechanism 4 includes a plurality of fixing plates 41 respectively fixed on the cover plate 1 and the inner wall of the shell body 2, a first spring 42 is installed on one side of the plurality of fixing plates 41, and one end of the plurality of first springs 42 is connected to a tube clamping plate 43, the plurality of tube clamping plates 43 are arc-shaped, and the plurality of tube clamping plates 43 can be combined to form an annular tube clamping member.

[0028] When in use, hot water can be first injected into the heating box 5 through the valve nozzle, and then one heating box 5 is placed into the heating cavity in the shell 2, and the infusion tube is laid in the arc groove on the heating box 5, and then another heating box 5 is covered on the infusion tube to clamp the infusion tube between the two heating boxes 5, and then the cover plate 1 is covered on the shell 2 and fixed, and then the infusion tube is heated by the heating box 5 to improve the comfort of the patient during infusion, and during use, the temperature of the heating box 5 can be checked through the temperature display on the cover plate 1. If the temperature of the heating box 5 is low and the heating effect on the infusion tube is not good, the cover plate 1 can be removed from the shell 2, and then the heating box 5 can be taken out of the shell 2, and the water in the heating box 5 can be poured out through the valve nozzle, and then hot water can be injected into the heating box 5 again, and the heating box 5 can be installed in the shell 2 to continue heating the infusion tube;

[0029] At the same time, when the infusion tube is laid between the two heating boxes 5 and the cover 1 is installed on the shell 2, the tube clamp composed of multiple tube clamping plates 43 at both ends of the cover 1 and the shell 2 clamps the infusion tube, and through the elasticity of the first spring 42, the tube clamp can clamp infusion tubes of different diameters, thereby fixing the heater on the infusion tube to prevent the heater from sliding along the infusion tube and causing its position to change, and the heater can be pulled along the infusion tube so that the heater straightens the bend of the infusion tube, which is beneficial to normal infusion and improves the practicality of the heater.

[0030] Specifically, Figure 1-Figure 4 As shown, connecting plates 7 are installed on both sides of the bottom of the cover plate 1, a connecting groove 8 corresponding to the connecting plate 7 is opened on the top of the shell 2, and locking screws 3 are screwed on both sides of the shell 2, and the connecting plate 7 has a screw hole that matches the locking screw 3.

[0031] When the cover plate 1 is installed on the shell 2, the cover plate 1 is first covered on the shell 2 so that the connecting plate 7 is inserted into the connecting groove 8, and then the locking screw 3 is screwed into the shell 2 to screw the cover plate 1 and the shell 2 together. When the heating box 5 needs to be taken out, the locking screw 3 can be unscrewed from the shell 2, and then the cover plate 1 can be removed from the shell 2, so as to achieve quick disassembly and assembly between the cover plate 1 and the shell 2, and facilitate the replacement of the heating box 5.

[0032] Furthermore, if Figure 2-Figure 4 As shown, positioning blocks 10 are installed at the four corners of the top of the shell 2, and positioning grooves 11 corresponding to the positioning blocks 10 are opened at the bottom of the cover plate 1.

[0033] When the cover plate 1 is installed on the shell 2 , the positioning block 10 on the shell 2 is inserted into the positioning groove 11 on the cover plate 1 to position the cover plate 1 and the shell 2 , thereby facilitating quick installation of the cover plate 1 and the shell 2 .

[0034] Furthermore, if Figure 2 As shown, the inner walls of the two arc-shaped grooves are both provided with cotton pads 6, and the two cotton pads 6 are both arc-shaped.

[0035] When the infusion tube is laid in the arc groove on the heating box 5, the cotton pad 6 can cushion the infusion tube to prevent the infusion tube from directly contacting the heating box 5 and can keep the infusion tube warm.

[0036] Furthermore, if Figure 1-Figure 5 As shown, a retractable linkage rod is connected between the fixing plate 41 and the tube clamping plate 43, and the first spring 42 is sleeved on the outside of the linkage rod.

[0037] During the expansion and contraction process of the first spring 42 , the linkage rod can be expanded and contracted synchronously therewith to support and stabilize the first spring 42 , which is beneficial to the stable expansion and contraction of the first spring 42 .

[0038] In addition, in one embodiment, if Figure 2-Figure 5 As shown, a pop-up mechanism 9 is also provided inside the cover 1 and the shell 2, and the pop-up mechanism 9 includes a plurality of concave cavities connected to the heating chamber, and a group of second springs 92 are fixed in each of the plurality of concave cavities, and the top of each group of second springs 92 is commonly connected to a pop-up plate 91, and the top of the pop-up plate 91 is in contact with the bottom of the heating box 5, and each group of second springs 92 can be set to 4, 6 or 9.

[0039] When taking out the heating box 5, first remove the cover plate 1 from the shell 2. At this time, the second spring 92 pushes the pop-up plate 91 upward under the action of its own elasticity, so that the pop-up plate 91 pops out the heating box 5 in the shell 2, so that the heating box 5 in the shell 2 can be quickly taken out, which is beneficial to the replacement of the heating box 5.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
