[0031] The host 100 is provided with a water circulation heating module. The heating tube sleeve 200 includes a heat-conducting inner sleeve 210 and a heat-insulating outer sleeve 220. The heat-conducting inner sleeve 210 is made of elastic heat-conducting material. The material of the heat-conducting inner sleeve 210 is selected as heat-conducting silicone. The cross section of the heat-conducting inner sleeve 210 is C-shaped, and a bayonet 211 extending along the length direction is formed on one side thereof. The wall of the heat-conducting inner sleeve 210 is provided with a water inlet channel 212 and a water return channel 213 extending along the length direction. The lower ends of the water inlet channel 212 and the water return channel 213 are interconnected, and the upper ends of the water inlet channel 212 and the water return channel 213 are respectively connected to the water outlet end and the water return end of the water circulation heating module. The heat-insulating outer sleeve 220 is wrapped on the outside of the heat-conducting inner sleeve 210, and the material of the heat-insulating outer sleeve 220 is preferably heat-insulating cotton.
[0032] In a specific embodiment, referring to Figure 1 The water circulation heating module includes a water tank 110, a water pump 120 and a heater 130 arranged in the host 100. The water outlet of the water tank 110 is connected to the water inlet of the water pump 120 through a pipe, the water outlet of the water pump 120 is connected to the upper end of the water inlet channel 212 through a pipe, and the upper end of the return water channel 213 is connected to the water inlet of the water tank 110 through a pipe. The water tank 110 is used to store circulating hot water, and a water replenishment port is provided on the upper part and an observation port is provided on the side. The water volume in the water tank 110 can be observed through the observation port. When the water volume in the water tank is insufficient, it can be replenished into the water tank 110 through the water replenishment port. The water pump 120 is used to provide power for hot water circulation, and the heater 130 is used to heat the circulating hot water.
[0033] Preferably, refer to Figure 1 and Figure 2 , a circulating water joint 140 is provided in the host 100, and a socket 141 is provided at the outer end of the circulating water joint 140 and is located outside the host 100, and an inner water inlet interface 142 and an inner water return interface 143 are provided at the inner end of the circulating water joint 140, and the water outlet of the water pump 120 is connected to the inner water inlet interface 142 through a pipeline, and the water inlet end of the water tank 110 is connected to the inner water return interface 143 through a pipeline. A plug joint 214 is provided at the upper end of the heat-conducting inner sleeve 210, and the plug joint 214 is plugged and matched with the socket 141, and two outer water inlet interfaces 215 and outer water return interfaces 216 are provided in the plug joint 214, which are respectively connected to the water inlet channel 212 and the water return channel 213, and the outer water inlet interface 215 is connected to the inner water inlet interface 142, and the outer water return interface 216 is connected to the inner water return interface 143. The heating sleeve 200 of this embodiment is plugged into the circulating water connector 140 on the host 100 via the plug connector 214, which facilitates the installation and removal of the heating sleeve 200.
[0034] In one embodiment, referring to Figure 2-Figure 5The two ends of the bayonet 211 of the heat-conducting inner sleeve 210 are arc-shaped, so that it is convenient to clip the infusion tube 400 into the heat-conducting inner sleeve 210 through the bayonet 211 .
[0035] In one embodiment, referring to Figure 3 and Figure 4 The outer walls of both ends of the bayonet 211 of the heat-conducting inner sleeve 210 are provided with outwardly protruding baffles 217, and the two side edges of the thermal insulation outer sleeve 220 are respectively against the side of each baffle 217 away from the bayonet 211. The baffles 217 block the side edges of the thermal insulation outer sleeve 220, which can protect the side edges of the thermal insulation outer sleeve 220 and prevent the infusion tube 400 from contacting the thermal insulation outer sleeve 220 when it is inserted.

The temperature sensing sheet is connected to the data interface of the host 100 through a data line 231, and the data line 231 extends from between the heat-conducting inner sleeve 210 and the heat-insulating outer sleeve 220 to the upper end, so that the liquid medicine temperature detected by the temperature sensing sheet can be transmitted to the host 100 through the data line 231 for display.
[0037] During infusion, the infusion tube 400 of the present embodiment is inserted into the heat-conductive inner sleeve 210, and the water circulation heating module passes the circulating hot water into the water inlet channel 212. The circulating hot water flows back to the water circulation heating module through the water inlet channel 212 and the return water channel 213 in turn, and then is circulated and heated by the water circulation heating module. The circulating hot water flowing through the water inlet channel 212 and the return water channel 213 heats the infusion tube 400 stuck in the heat-conductive inner sleeve 210, thereby heating the medicine passing through the infusion tube 400. The medicine is heated evenly, which is convenient for controlling the heating temperature. The infusion tube 400 is convenient to combine with the heating tube sleeve 200. At the same time, a thermal insulation outer sleeve 220 is provided outside the heat-conductive inner sleeve 210, which can reduce the heat loss of the circulating hot water flowing through the heating tube sleeve 200. Therefore, compared with the prior art, the present application solves the problems of inconvenient wrapping operation of the infusion tube 400 and large heat loss of circulating hot water.
