Description

Technical Field

[0001] The utility model relates to a heating device, in particular to a nutrient solution heating device. Background Art

[0002] Nutrient solution is usually introduced into the digestive system through nasogastric tube and nasointestinal tube. The time of introduction is generally two to four hours. At this time, the temperature of the nutrient solution will become cold. During the cooling process, the patient will experience gastrointestinal intolerance when it is introduced. In severe cases, nausea, vomiting, and diarrhea will occur. This situation is especially obvious in winter because the gastrointestinal tract is more sensitive to temperature stimulation, and the gastrointestinal function of critically ill patients is relatively low. Nutrient solution close to human body temperature has better absorption rate and gastrointestinal tolerance. Therefore, such patients need to use corresponding heating devices to heat the nutrient solution to the required temperature when introducing nutrient solution.

[0003] However, the heating device in the prior art only provides a heater on a small section of the infusion tube. The heater cannot fully heat the nutrient solution in the infusion tube, resulting in uneven heating of the nutrient solution in the infusion tube, which ultimately reduces the patient's absorption rate of the nutrient solution and causes discomfort to the patient's stomach and intestines.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0021] like Figures 1 to 4 A nutrient solution heating device is shown, comprising a front shell 5 and a rear shell 6, wherein the front shell 5 and the rear shell 6 are matched with each other to form a sealing structure; a heating component 3 is arranged in the sealing structure;

[0022] The heating assembly 3 includes a front heat-conducting silicone sheet 32, a rear heat-conducting silicone sheet 34, a front guide groove 37, and a rear guide groove 36; the front heat-conducting silicone sheet 32 ​​is arranged in the front housing 5, and the rear heat-conducting silicone sheet 34 is arranged in the rear housing 6. The front heat-conducting silicone sheet 32 ​​and the rear heat-conducting silicone sheet 34 are both provided with electric heating wires 38, and the electric heating wires 38 are connected to the thermostat 32, and the thermostat 32 is connected to a power supply;

[0023] The front heat-conducting silicone sheet 32 ​​is provided with a front guide groove 37, and the rear heat-conducting silicone sheet 34 is provided with a rear guide groove 36; the front guide groove 37 and the rear guide groove 36 are provided with an infusion tube 2. In the present application, the infusion tube 2 is connected to the nutrient solution storage bag 1.

[0024] When it is necessary to heat the nutrient solution in the infusion tube 2 when the nutrient solution is infused to the patient, the lower end of the infusion tube 2 to be heated is embedded in the front guide groove 37 or the rear guide groove 36. After the embedding is completed, the front shell 5 and the rear shell 6 can be closed. Then the medical staff connects the temperature controller 32 to the external power supply through the wire, and controls the multiple electric heating wires 38 to work according to the preset temperature value through the temperature controller 32, so that the multiple electric heating wires 38 heat the front heat-conducting silicone sheet 33 and the rear heat-conducting silicone sheet 34 respectively. , thereby making the front heat-conductive silicone sheet 33 and the rear heat-conductive silicone sheet 34 heat the infusion tube 2 in contact with each other. Due to the opening of the front guide groove 37 or the rear guide groove 36, the path of the infusion tube 2 inside the front heat-conductive silicone sheet 33 and the rear heat-conductive silicone sheet 34 becomes longer, so that the heated front heat-conductive silicone sheet 33 and the rear heat-conductive silicone sheet 34 can fully heat the nutrient solution flowing through the infusion tube 2 to ensure the temperature of the nutrient solution input into the patient's body, thereby facilitating the improvement of the patient's absorption rate of the nutrient solution and reducing the patient's gastrointestinal discomfort.

[0025] As a preferred embodiment, the front housing 5 and the rear housing 6 are connected by an opening and closing assembly 4, and the opening and closing assembly 4 includes a hinge 41, a connecting buckle 43 and a connecting hook 42. One end of the front housing 5 and one end of the rear housing 6 are connected by a hinge 41, and the other end of the front housing 5 is provided with a connecting hook 42, and the other end of the rear housing 6 is provided with a connecting buckle 43, and the connecting hook 42 matches the connecting buckle 43. The setting of the hinge facilitates the closing and opening of the front housing 5 and the rear housing 6, and the setting of the connecting hook and the connecting buckle facilitates the locking between the front housing 5 and the rear housing, and facilitates the fixing of the infusion tube by the heating device.

[0026] As a preferred embodiment, the front housing 5 in the present application is provided with a front baffle 31, the rear housing 6 is provided with a rear baffle 35, and a heat insulation layer 311 is provided between the front heat-conducting silicone sheet 32 ​​and the front baffle 31, and between the rear heat-conducting silicone sheet 34 and the rear housing 6. The heat insulation layer 311 improves the heat insulation capacity of the front baffle 31 and the rear baffle 35, prevents the heat generated by the multiple electric heating wires 38 from being quickly lost to the outside through the front baffle 31 or the rear baffle 35 when working, and improves the heating efficiency of the nutrient solution heating device for the nutrient solution in the infusion tube.

[0027] In the present application, the front heat-conducting silicone sheet 32 ​​and the rear heat-conducting silicone sheet 34 are respectively provided with a clamping block 331, and the front heat-conducting silicone sheet 32 ​​and the rear heat-conducting silicone sheet 34 are respectively arranged on the front shell 5 and the rear shell 6 through the clamping blocks 34. The arrangement of the clamping block 331 prevents the front heat-conducting silicone sheet 33 and the rear heat-conducting silicone sheet 34 from being easily loosened and falling off during use, and later medical personnel can also use the device repeatedly by disassembling, disinfecting, cleaning or replacing the front heat-conducting silicone sheet 33 and the rear heat-conducting silicone sheet 34 separately.

[0028] The electric heating wire 38 in the present application is respectively arranged on the front heat-conducting silicone sheet and the rear heat-conducting silicone sheet through the support seat 39. The support seat 39 supports and fixes the electric heating wire 38.

[0029] In the present application, the front guide groove and the rear guide groove are both S-shaped. The S-shaped front guide groove 37 or rear guide groove 36 lengthens the path of the infusion tube 2 inside the front thermal conductive silicone sheet 33 and the rear thermal conductive silicone sheet 34, so as to fully heat the nutrient solution flowing through the infusion tube 2 and improve the heating efficiency of the nutrient solution in the infusion tube.

[0030] The nutrient solution heating device of the present invention lengthens the path of the infusion tube inside the front heat-conducting silicone sheet and the rear heat-conducting silicone sheet by setting the front guide groove and the rear guide groove, so as to fully heat the nutrient solution flowing through the infusion tube and avoid uneven heating of the nutrient solution in the infusion tube. At the same time, the thermal insulation layer will further improve the thermal insulation capacity of the front baffle and the rear baffle, and avoid the heat generated by multiple electric heating wires when working to be quickly lost to the outside through the front baffle or the rear baffle, thereby ensuring the heating effect of the electric heating wire. The setting of the hinge, the connecting buckle and the connecting hook can realize the opening between the front shell and the rear shell or the locking after the front and rear shells are closed, which is convenient for fixing the infusion tube and improving the heating and fixing efficiency of the infusion tube.
