Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an infusion hose heater. Background Art

[0002] An infusion hose heater is a device that heats infusion hoses. It's commonly used in winter, especially for pediatric patients. It heats the liquid medicine inside the tube, ensuring it flows into the bloodstream at a moderate temperature.

[0003] Currently, portable heating devices use chemical reaction heating and are disposable products. Although these products are low-cost, they are in high demand and are disposed of as medical waste after use, which is a waste of resources.

[0004] In addition, infusion hoses are usually heated in the exposed state, which results in poor heating effect. Utility Model Content

[0005] In view of the above problems, the purpose of the present invention is to provide an infusion hose heater to solve the above technical problems.

[0006] The utility model adopts the following technical solutions:

[0007] The infusion hose heater includes a heating column and an insulation sleeve. The surface of the heating column has a forward spiral groove and a reverse spiral groove, and the two spiral grooves are connected at the top. The bottom edge of the heating column also has a bottom groove that is connected to the two spiral grooves in a one-to-one correspondence. The inner diameter of the insulation sleeve matches the diameter of the heating column. There is a heating cavity in the heating column, and a heating wire is wound in the heating cavity.

[0008] Furthermore, there is a conductive slot on the top of the heating column, a conductive plug on the top of the insulation sleeve, and a power supply module inside the insulation sleeve. The power supply module is connected to the conductive plug, and the conductive slot is connected to the heating wire.

[0009] Furthermore, the inner wall of the thermal insulation sleeve has a thermal insulation layer.

[0010] Furthermore, a pull block is provided at the tail of the heating column.

[0011] The beneficial effects of the present invention are as follows: the surface of the heating column of the present structure has two spiral grooves in opposite directions, which are connected at the top. The infusion hose is first wound around the forward spiral groove and then continuously wound around the reverse spiral groove, and finally led out from the bottom groove and covered with a thermal insulation sleeve; through this design, the heating length of the infusion hose is lengthened and the heating effect is improved; in addition, the thermal insulation sleeve is designed to prevent heat from being lost quickly, further improving the use effect.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0018] like Figure 1-4 As shown, the infusion hose heater provided in this embodiment includes a heating column 1 and an insulation sleeve 2. The surface of the heating column 1 has a forward spiral groove 3 and a reverse spiral groove 4, and the two spiral grooves are connected at the top. The bottom edge of the heating column 1 also has a bottom groove 5 that is connected to the two spiral grooves one by one. The inner diameter of the insulation sleeve 2 matches the diameter of the heating column 1. The heating column 1 has a heating cavity 6, and the heating cavity 6 is wound with a heating wire 7.

[0019] This product utilizes electric heating and consists of two components: a heating cylinder 1 and an insulation sleeve 2. The heating cylinder 1 can be inserted into the insulation sleeve 2. In existing designs, the infusion hose is wrapped directly around the surface of the heating cylinder, resulting in rapid heat loss and poor heating performance. In this design, the insulation sleeve 2 acts as a heat insulator, preventing rapid heat loss and improving heating effectiveness. Furthermore, the inner wall of the insulation sleeve is insulated.

[0020] In this structure, there are two spiral grooves in both directions on the surface of the heating column, and there is a bottom groove at the bottom of each spiral groove. When in use, the infusion hose is first inserted into one bottom groove, and then wound upward along the forward spiral groove. After reaching the top, it is then wound downward along the reverse spiral groove, and finally led out from the other bottom groove. Therefore, the design of the forward and reverse spiral grooves can multiply the heating length of the infusion hose and significantly improve the heating effect. It should be noted that the depth of the spiral groove is close to twice the outer diameter of the infusion hose, and there will be no interference at the intersection. In addition, the inner diameter of the insulation sleeve matches the diameter of the heating column, and there is friction between the two, so the insulation sleeve will not fall off at will.

[0021] For a specific structure of the electric heating method, there is a conductive slot 11 on the top of the heating column 1, a conductive plug 21 is provided on the top of the insulation sleeve 2, and a power supply module 22 is provided in the insulation sleeve 21. The power supply module 22 is connected to the conductive plug 21, and the conductive slot 11 is connected to the heating wire 7. There is a guide port at the port position of the conductive slot 11. After inserting the heating column, the heating column or the insulation sleeve is rotated so that the conductive plug 21 is aligned with the conductive slot 11 and inserted. In order to facilitate operation, there is a pull block 12 at the tail of the heating column 1. At the same time, the pull block also facilitates the operation of removing the heating column.

[0022] The power supply module is powered by a rechargeable battery, and there is a charging port 23 on the top of the insulation cover. In this way, the protective cover can be replaced. That is, during the heating process, if the battery power is low, you can directly replace it with a fully charged protective cover to continue heating without removing the infusion hose and replacing the entire product, which is more convenient to use.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
