Description

Technical Field

[0001] The utility model relates to the technical field of infusion heating, in particular to an auxiliary heater suitable for infusion tubes of multiple sizes. Background Art

[0002] Intravenous infusion is a commonly used treatment method in clinical medicine. During the infusion process, body fluids, electrolytes or nutrients are continuously replenished to the patient's body through the infusion tube. The storage temperature of the liquid medicine is generally below 5°. The temperature is even lower in winter, generally around 0°. During the infusion, there is a large difference between the patient's body temperature and the liquid temperature. The puncture and injection sites of the patient's body are easily stimulated by the cold and cause discomfort.

[0003] In order to avoid irritation and discomfort to patients caused by large temperature differences during infusion, medical staff usually use hot water bottles and heat packs to apply to the outside of the infusion tube to heat the liquid medicine before it enters the patient's body. During use, this method has a short heating duration and poor effect because the temperature of the method itself is not high and it is easy to cool down in a short time in a low temperature environment.

The heating water source is driven by a micro water pump to circulate inside the heat exchange micro tube, and heat exchange is performed with the infusion tube passing through the inside of the heating tube from downward to upward, so as to continuously heat the infusion tube. In actual application, an infusion set of suitable size needs to be selected for different dosages. The outer diameters of infusion tubes of different infusion sets are different. If the outer diameter of the infusion tube is large, it cannot be placed in the heating tube. If the inner diameter of the infusion tube is small, the infusion tube and the heating tube cannot be in contact as much as possible, and the heat exchange effect is poor. Therefore, the prior art cannot meet the conditions for achieving the corresponding heating effect during the heating process of infusion tubes of different sizes. Utility Model Content

[0036] 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.

[0037] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides an auxiliary heater suitable for infusion tubes of various sizes, comprising a heating chamber 2 and a heat exchange return pipe 1.

[0038] A micro water pump 21 and an electric heater 22 are installed in the heating chamber 2. A water inlet 4 is provided on the top of the heating chamber. Before heating the infusion tube 5, an appropriate amount of water needs to be injected into the heating chamber 2 through the water inlet 4, and then the electric heater 22 is turned on.

[0039] In order to automatically control the electric heating during the infusion process, a microcontroller, a battery and a corresponding mounting structure can also be arranged outside the heating cabin 2. The battery can power the microcontroller and the electric heater 22. A temperature sensor is arranged in the heating cabin 2. The temperature sensor is communicated with the microcontroller. The temperature sensor transmits the liquid temperature data in the heating cabin collected in real time to the microcontroller. The microcontroller analyzes the temperature data. If it is lower than a certain temperature, the electric heater 22 is controlled to start heating. If it exceeds a certain temperature, the electric heater 22 is controlled to stop heating, thereby realizing automatic control of the heating process of the electric heater 22. The above-mentioned automatic control procedures are all performed after liquid is injected into the heating cabin 2 (there is liquid in the heating cabin 2).

[0040] The micro water pump 21 is used to pump the hot water in the heating chamber 2 into the heat exchange return pipe 1. The micro water pump 21 is in a normally open state during the infusion process to ensure that the hot water in the heat exchange return pipe 1 is always maintained within a certain temperature range. In addition, the micro water pump 21 also requires an external power supply.

[0041] like Figure 1 As shown, the heat exchange return pipe 1 extends from the outer pipe outlet 6 of the heating chamber 2 along the outer circumference of the infusion tube 5 for at least half a circle and then bends back to extend into the heating chamber 2. The heat exchange return pipe 1 goes around the infusion tube 5 at least half a circle and then returns to the heating chamber 2 along the original path. The above is the direction of the heat exchange return pipe 1, that is, both ends of the heat exchange return pipe 1 are placed in the heating chamber 2, and a single heat exchange return pipe 1 forms a double-layer pipe body structure. The hot water in the heating chamber 2 passes through the single heat exchange return pipe 1 to form a double-layer heat exchange path, and performs double heat exchange with the liquid medicine in the infusion tube 5, further ensuring the heat exchange effect.

[0042] In addition, in order to make the heat exchange return pipe 1 basically close to the outer wall of the infusion tube 5, a binding patch 3 is provided at the bending part of the heat exchange return pipe 1. The binding patch 3 positions the bending part of the heat exchange return pipe 1 on the side outside the heating chamber 2 away from the pipe outlet 6, so as to bind the infusion tube 5 in the heat exchange return pipe 1 in a tightly fitting state. Therefore, this design is suitable for infusion tubes with any outer diameter. The infusion tube 5 with any outer diameter is placed on the side of the heating chamber 2, and the infusion tube 5 is tightly fixed in the heat exchange return pipe 1 by the binding patch 3. The tight fit ensures the corresponding heat exchange rate.

[0043] In the utility model, Figure 3 As shown, the heat exchange return pipe 1 is provided in a plurality of pieces, and the two ends of the heat exchange return pipe 1 extending to the heating chamber 2 respectively form a water inlet pipe port 7 and a water outlet pipe port 8, wherein the plurality of water inlet pipe ports 7 are connected in series through a main pipe 9, and a micro water pump 21 is installed on the main pipe 9.

[0044] Driven by the micro water pump 21, the hot water in the heating chamber 2 enters the main pipe 9, and then enters the corresponding heat exchange return pipe 1 through multiple water inlet pipes 7, and then flows back to the heating chamber 2 through the heat exchange return pipe 1. The heat exchange return pipe 1 and the heating chamber 2 as a whole can be regarded as forming a heat exchange loop, which realizes the real-time replacement of the liquid in the pipe and ensures the heating effect.

[0045] Initially, the outer wall of the heat exchange return pipe 1 is basically at room temperature, and the temperature gradually rises after hot water is injected into it. Therefore, in order to ensure the effect of heating the liquid medicine, the micro water pump 21 should be turned on for a period of time before the infusion work is carried out.

[0046] In order to ensure that the upper and lower tube bodies of the heat exchange return pipe 1 can fit tightly with the infusion tube 5, it is necessary to align the positions of the upper and lower tube bodies and the corresponding outlet pipes 6. In addition, in order to avoid interference between the main pipe 9 and the outlet pipe 8, a certain space needs to be set between the main pipe 9 and the outlet pipe 8. Therefore, it is necessary to make the length of the water inlet pipe 7 greater than the length of the outlet pipe 8. Correspondingly, the main pipe 9 is located away from the outlet pipe 8. On the one hand, this can avoid the main pipe 9 blocking the outlet pipe 8. On the other hand, it can enable the hot water that has passed through a heat exchange circuit to be heated in the cabin for a certain period of time when it re-enters the heating cabin 2 and then be discharged from the inlet pipe 7.

[0047] In the utility model, the heat exchange return pipe 1 can form a heat exchange loop, and the heat exchange return pipe 1 includes a flushing pipe 11 and a return pipe 12 arranged in sequence. The flushing pipe 11 and the return pipe 12 are respectively the upper and lower pipe bodies of the heat exchange loop, wherein the flushing pipe 11 and the return pipe 12 can both be made of medical soft silicone tube material, which can be bent and wrapped around the outside of the infusion tube 5 to fully contact the outer wall of the infusion tube 5.

[0048] like Figure 2 As shown, the flush pipe 11 and the return pipe 12 are connected, the bending part of the heat exchange return pipe 1 is located between the flush pipe 11 and the return pipe 12, and the flush pipe 11 and the return pipe 12 are connected by a bending support tube 13, wherein the flush pipe 11 and the return pipe 12 are both made of soft materials, and in order to avoid the pipe walls overlapping at the bending part so as to prevent the liquid from being unable to flow, the bending support tube 13 arranged at the bending part is a hard structure, which supports and connects the ends of the flush pipe 11 and the return pipe 12 to maintain a certain gap between the flush pipe 11 and the return pipe 12 to prevent the bending part from folding.

[0049] The bending angle between the upper end and the lower end of the bending support tube 13 provided at the bending part of the heat exchange return pipe 1 is 360°.

[0050] The restraining patch 3 fixes the curved support tube 13 to fix the heat exchange return pipe 1 as a whole. The restraining patch 3 includes a ring pull rope 31 arranged around the outer periphery of the curved support tube 13 and a Velcro 32 connected to the end of the ring pull rope 31. The outer wall of the heating chamber 2 facing the bend of the heat exchange return pipe 1 is recessed inward to form a concave cavity 10. The inner wall of the concave cavity 10 is installed with a Velcro mother patch 33, and the Velcro son patch 32 is pasted on the Velcro mother patch 33.

[0051] Correspondingly, the number of Velcro mother patches 33, concave cavities 10 and Velcro son-shaped patches 32 is consistent, and is consistent with the number of heat exchange return pipes 1. In actual application, only one concave cavity 10 and one Velcro mother patch 33 may be provided, and the ends of multiple ring pull ropes 31 are all connected to one Velcro son-shaped patch 32, and then one Velcro son-shaped patch 32 is pasted on a corresponding Velcro mother patch 33 for fixation.

[0052] In order to support the infusion tube 5, a side arc groove 14 is vertically opened outside the heating chamber 2, and the outer wall of the infusion tube 5 at least partially fits the side arc groove 14. The infusion tube 5 is arranged along the vertical direction. In order to further improve the heat exchange rate, a heating plate can also be installed in the side arc groove 14. However, the infusion tube 5 has a variable size, and its outer wall does not completely fit the inner wall of the side arc groove 14, and cannot completely fit the shape of the heating plate. Therefore, the heating process in this design mainly relies on the heat exchange work of the heat exchange return pipe 1.

[0053] A sealing cover 15 is installed on the water injection port 4 to ensure the sealing of the interior of the heating chamber 2.

[0054] 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.
