Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, and in particular to a nutrition tube warmer which is convenient for temperature control. Background Art

[0002] The temperature generated by the heating strip of the nutrition tube warmer currently used in clinical practice generally reaches 65° to ensure that the nutrient solution in the pipe is heated to human body temperature, which is about 37°. The outer layer of the warmer is protected by a plastic shell to prevent the nutrient solution from scalding the patient when the temperature has not reached self-cooling.

[0003] Generally, in clinical use, the warmer needs to be far away from the patient, but if the distance is too far, it is easy to cause the heated nutrient solution to lose temperature during long-distance flow. In the prior art, a temperature controller is usually used to control the heating cylinder to adjust the temperature of the delivered nutrient solution, and the nutrient tube passes directly through the heating cylinder to use its heating function to heat the nutrient tube once, thereby ensuring that the temperature of the nutrient solution reaches the human body temperature when it enters the patient's body. However, there are many uncontrollable factors in the process of nutrient solution being transported along the nutrient tube, which can easily cause the delivery temperature of the nutrient solution to be inaccurate, such as bending or damage of the nutrient tube.

[0004] Therefore, it is necessary to provide a nutrition tube warmer that is easy to control temperature so as to improve the heating stability of the existing warmers. Utility Model Content

[0005] The purpose of the utility model is to provide a nutrition tube warmer which is convenient for temperature control, so as to solve the technical problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0008] Furthermore, a guide plate is provided at the end of the heating channel, and the guide plate is used to change the direction of the end of the nutrition tube after passing through one end of the heating channel; wherein the guide plate is an arc-shaped structure with the end bent toward the insulation channel.

[0009] Furthermore, the support portion includes a telescopic rod, so that the length of the exposed section of the nutrition tube can be increased / reduced by the extension / contraction action of the telescopic rod; wherein the end of the telescopic rod is provided with a groove for fixing the nutrition tube.

[0010] Furthermore, a rubber inner tube is provided in the heating channel and the heat preservation channel respectively to fit the nutrition tube; wherein the inner wall of the rubber inner tube protrudes inward to form an air cavity, and the air cavity can produce elastic deformation when squeezed by the nutrition tube;

[0011] A plurality of air cavities are arranged at equal intervals on the peripheral wall of the rubber inner tube.

[0012] Furthermore, a temperature detector is provided inside the groove and fits the nutrition tube to detect the temperature of the nutrition tube.

[0013] Furthermore, the outer cover of the heating tube is provided with a mesh protective cover.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0030] like Figure 1 , 6 As shown in , 7, the utility model provides a nutrient tube warmer that is easy to control temperature, including:

[0031] The heating cylinder 1 has a heating channel 11 and a heat preservation channel 12 extending along its axis for passing the nutrition tube 3 to be heated;

[0032] The support part 2 is arranged at the end of the heating tube 1 and between the ends of the heating channel 11 and the heat preservation channel 12, and the support part 2 is in contact with a portion of the nutrition tube 3;

[0033] The middle part of the heating tube 1 is divided into a heating zone 13 and a heat preservation zone 14 respectively provided with electric heating wires. The heating zone 13 is close to the heating channel 11, and the heat preservation zone 14 is close to the heat preservation channel 12. The power of the electric heating wire in the heating zone 13 is greater than that in the heat preservation zone 14.

[0034] The utility model aims to achieve different degrees of heating effect on the nutrition tube 3 by successively passing the nutrition tube 3 through the heating channel 11 and the insulation channel 12 arranged inside the heating cylinder 1, and then through the electric heating wires of different powers respectively arranged in the heating area 13 and the insulation area 14, thereby reducing the heat loss of the nutrient solution in the nutrition tube 3 and improving the insulation effect of heating the nutrient solution delivered to the patient by the heating cylinder 1; on the other hand, the utility model can also support and guide the portion of the nutrition tube 3 exposed outside the heating cylinder 1 through the arrangement of the support part 2, so as to avoid excessive bending of the nutrition tube 3 before entering the insulation channel 12, which may cause obstruction of the nutrient solution delivery, and is not conducive to timely supplementation of necessary nutrients to the patient's body. It should be noted that, in actual use, the heater provided by the utility model can increase the length of the nutrient tube 3 exposed outside the heating tube 1 by arranging support portions 2 of different heights at the end of the heating tube 1, so as to accelerate the temperature loss process of the nutrient solution inside the nutrient tube 3, thereby reducing the temperature of the nutrient solution after passing through the insulation channel 12, thereby achieving temperature regulation of the nutrient solution, and also enabling the user to monitor the temperature of the nutrient solution in real time and observe the delivery of the nutrient solution in real time, thereby avoiding problems that affect the patient's health due to obstruction of nutrient solution delivery, too low nutrient solution delivery temperature, etc.

[0035] In order to facilitate the nutrition tube 3 to pass through one end of the heating channel 11 and enter the end close to the heat preservation channel 12, as shown in FIG. Figure 2-3 As shown, in another embodiment provided by the present invention based on the above embodiment, a guide plate 15 is provided at the end of the heating channel 11, and the guide plate 15 is used to change the direction of the end of the nutrition tube 3 after passing through one end of the heating channel 11;

[0036] The guide plate 15 is an arc-shaped structure with its end bent toward the heat preservation channel 12 .

[0037] In this embodiment, by setting the guide plate 15, the nutrition tube 3 can be easily passed through one end of the heating channel 11 and enter the end close to the insulation channel 12, which simplifies the operation process of inserting the nutrition tube 3 into the heating tube 1 and improves the insertion efficiency of the nutrition tube 3. It can avoid the medical staff from passing the nutrition tube 3 through the heating channel 11 and leaving the exposed part too long, causing the nutrition tube 3 to be excessively bent, which can easily cause local damage to the nutrition tube 3 and cause leakage during the nutrient solution delivery process.

[0038] In the above embodiment, although the height of the support portion 2 can be pre-set, it is not convenient for medical staff to make timely adjustments according to actual heating conditions during use, that is, it is not convenient to adjust the heating degree by adjusting the exposed length of the nutrition tube 3.

[0039] To solve the above problems, please continue to refer to Figure 2-3 As shown, in another embodiment provided by the present invention based on the above embodiment, the support portion 2 includes a telescopic rod 21, so that the length of the exposed section of the feeding tube 3 can be increased / reduced by the extension / contraction action of the telescopic rod 21;

[0040] The end of the telescopic rod 21 is provided with a groove 211 for fixing the feeding tube 3 .

[0041] In this embodiment, by setting the telescopic rod 21, it can utilize its own telescopic effect to increase or reduce the part of the nutrition tube 3 exposed outside the heating tube 1, thereby accelerating the temperature loss process of the nutrient solution after flowing through the heating channel 11, and achieving the purpose of adjusting the heating effect by lowering the temperature of the nutrient solution before entering the insulation channel 12.

[0042] In the above embodiment, in order to ensure the stability of the nutrition tube 3, the inner diameters of the heating channel 11 and the insulation channel 12 are usually equivalent to the diameter of the nutrition tube 3. A too tight fit will make it difficult for the nutrition tube 3 to penetrate therein, and a too loose fit will reduce the contact area between the heating zone 13, the insulation zone 14 and the nutrition tube 3, thereby reducing the heating effect of the heating tube 1 on the nutrition tube 3.

[0043] In order to solve the above problems, Figure 4-5 As shown, in another embodiment provided by the present invention based on the above embodiment, a rubber inner tube 16 is respectively provided in the heating channel 11 and the heat preservation channel 12 to fit with the nutrition tube 3;

[0044] The inner wall of the rubber inner tube 16 bulges inward to form an air cavity 161 , and the air cavity 161 can generate elastic deformation when squeezed by the nutrition tube 3 ; a plurality of air cavities 161 are equidistantly arranged on the peripheral wall of the rubber inner tube 16 .

[0045] In this embodiment, by providing a flexible rubber inner tube 16, the limiting space for the nutrition tube 3 in the heating channel 11 and the insulation channel 12 is variable, so that adaptive expansion can be formed during the insertion of the nutrition tube 3, and by providing an air cavity 161 surrounding the nutrition tube 3 on the rubber inner tube 16, the flexible deformation ability of the rubber inner tube 16 is further increased, so that the rubber inner tube 16 can play a stable limiting role on the nutrition tube 3, thereby preventing the nutrition tube 3 from slipping significantly relative to the heating tube 1 when subjected to external force, thereby affecting the heating and insulation effect of the heating tube 1 on the nutrition tube 3.

[0046] In order to monitor and feedback the temperature of the nutrition tube 3 , the present invention can further provide a temperature detector in the groove 211 based on the above embodiment to fit the nutrition tube 3 so as to detect the temperature of the nutrition tube 3 .

[0047] In order to avoid low-temperature burns caused by long-term contact with the heating tube 1 when the user uses it for a long time, Figure 8 As shown, in another embodiment provided by the utility model based on the above embodiment, the outer sleeve of the heating tube 1 is provided with a mesh protective sleeve 4. In this embodiment, the heating tube 1 is wrapped by the mesh protective sleeve 4, which can reduce the heat transfer capacity of the heating tube 1, thereby preventing the patient from being burned by low temperature during use.

[0048] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
