Detailed Description
The accompanying drawings illustrate embodiments of the present disclosure and it is to be understood that the disclosed embodiments are merely examples of the disclosure, which can be embodied in various forms, and therefore, specific details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure.
Referring to fig. 1 to 3, the infusion device 100 includes a first housing 1, a second housing 2, a thermoelectric Cooler (Thermal Cooler)3, a temperature sensor 4, and a thermostat 5.
The first housing 1 and the second housing 2 can be assembled together, and a part of the infusion tube 200 can be accommodated in the combined first housing 1 and second housing 2. Thermoelectric refrigerator 3 has hot end 31, and hot end 31 is adjacent to infusion tube 200, and hot end 31 is used for delivering heat to infusion tube 200 to heat the liquid medicine in infusion tube 200. The temperature sensor 4 is arranged in the combined first shell 1 and second shell 2 and is positioned at the downstream of the thermoelectric refrigerator 3 in the direction in which the liquid medicine in the liquid conveying pipe 200 is to be conveyed, and the temperature sensor 4 is used for sensing the temperature of the liquid conveying pipe 200 heated by the hot end 31 of the thermoelectric refrigerator 3. The temperature controller 5 is connected to the thermoelectric refrigerator 3 and the temperature sensor 4 in a communication manner, and the temperature controller 5 is used for controlling the working power of the thermoelectric refrigerator 3 according to the temperature of the heated infusion tube 200 sensed by the temperature sensor 4 so as to control the temperature of the heated infusion tube 200.
In the infusion apparatus 100 of the present disclosure, heat is transferred to the infusion tube 200 through the hot end 31 of the thermoelectric refrigerator 3 to heat the medical fluid in the infusion tube 200, so that the heated medical fluid is transferred to the human body through the infusion tube 200 immediately after the medical fluid is taken out from the refrigerated environment and the human body is infused, thereby avoiding the impact of low temperature on the human body and improving the comfort of the human body during infusion.
Due to the characteristics of the thermoelectric refrigerator 3, the temperature rises rapidly, the temperature control precision is high, and the temperature uniformity is good, so that the heated liquid medicine can reach the proper temperature before being conveyed into a human body, the comfort of the human body during transfusion is improved, and the liquid medicine deterioration caused by overhigh heating temperature can be avoided.
The infusion device 100 is simple in construction due to the use of the thermoelectric cooler 3 as compared to the use of a fluid medium, such as water.
In one example, the first housing 1 and the second housing 2 are detachably fixed to each other at both ends in a direction in which the infusion tube 200 extends. Specifically, the first housing 1 and the second housing 2 may be detachably connected at different or the same positions along the extension direction of the infusion tube 200. For example, the housing 1 and the second housing 2 are snap-connected at the downstream end in the extending direction of the infusion tube 200. For example, the first and second housings 1 and 2 are provided with external threads at the upstream end portions in the extending direction of the infusion tube 200, and the infusion apparatus 100 further includes a nut 6 provided with internal threads, the nut 6 being screwed and fixed together with the end portions of the first and second housings 1 and 2.
To enhance the heat transfer effect, in an example, referring to fig. 2, the infusion device 100 further includes a first heat conduction layer 7 and a thermal insulation layer 8, the first heat conduction layer 7 is disposed on the first casing 1, the first heat conduction layer 7 is used for directly contacting the infusion tube 200, the first thermal insulation layer 8 is disposed outside the first heat conduction layer 7, and the first thermal insulation layer 8 is used for preventing the heat of the first heat conduction layer 7 from being transferred outwards. Thereby increasing the heat transfer and insulation effects to the infusion tube 200. The first heat conducting layer 7 may be a high heat conducting material, such as a heat conducting ceramic layer, a metal layer. The metal layer is, for example, a copper layer.
Furthermore, the infusion device 100 comprises a second heat conducting layer 11, the second heat conducting layer 11 being arranged on the hot end 31 of the thermoelectric cooler 3 for direct contact with the infusion tube 200. Through second heat-conducting layer 11, improve the heat transfer effect to transfer line 200, reinforcing heating efficiency.
Referring to fig. 2, in one example, the second housing 2 is provided with a vacuum chamber S, the thermoelectric cooler 3 is located within the vacuum chamber S, and the second heat conducting layer 11 seals the vacuum chamber S. The vacuum chamber S is provided to improve the service life of the thermoelectric refrigerator 3 and prevent the air in the vacuum chamber S from oxidizing the material of the thermoelectric refrigerator 3. In addition, as shown in fig. 2, the thermoelectric refrigerator 3 further has a cold end 32, the cold end 32 is also enclosed in the vacuum cavity S, and since the second heat conducting layer 11 encloses the vacuum cavity S, the cold end 32 and the air in the vacuum cavity S can be prevented from forming condensation or frost to further damage the thermoelectric refrigerator 3. Further, as shown in fig. 2, the cold end 32 dissipates heat by contact with the second housing 2.
Referring to fig. 2, the infusion device 100 further comprises a detachable built-in power supply 9, and the built-in power supply 9 is disposed in the first housing 1 and electrically connected to the temperature controller 5 and the thermoelectric refrigerator 3. The provision of the built-in power supply 9 enables the infusion device 100 to be disconnected from a fixed external power supply connection, improving the portability of the infusion device 100. The internal power source 9 is electrically connected to the thermostat 5, for example, through a connector (not shown) provided in the first housing 1, and the internal power source 9 is electrically connected to the thermoelectric refrigerator 3, for example, through another connector provided in the second housing 2, and the two connectors are detachably mated, thereby achieving detachable connection of the internal power source 9.
In order to improve portability, in one example, the internal power source 9 is a rechargeable battery, the infusion device 100 further comprises an external interface 10, the external interface 10 is disposed on the first housing 1 and electrically connected to the internal power source 9 and the temperature controller 5, and the external interface 10 is used for connecting an external power source (not shown) so that the external power source directly serves as a power source for the infusion device 100 or charges the internal power source 9.
Referring to fig. 4, the first layer 7 and the second layer 11 cooperate with each other to form a fluid conduit well G that houses the fluid conduit 200. Since the heat conduction functions of the first heat conduction layer 7 and the second heat conduction layer 11 are simultaneously performed, the heat transfer area can be increased, and the heating efficiency can be improved. Further, the infusion tube grooves G contact each other and form an interference fit with the infusion tube 200 when assembled with the first housing 1 and the second housing 2. This further enhances the heat transfer and limits the infusion tube 200, thereby preventing the needle (not shown) connected to the infusion tube 200 from coming off the body when the infusion tube 200 is pulled by an external force (e.g., in the opposite direction of the infusion). Further, as shown in fig. 4, the infusion tube groove G is bent back and forth in a direction perpendicular to the direction in which the first housing 1 and the second housing 2 face each other, so as to prevent the needle connected to the infusion tube 200 from coming off the human body when the infusion tube 200 is pulled by an external force (for example, pulled in the opposite direction of the infusion).
The above detailed description is used to describe a number of exemplary embodiments, but is not intended to limit the combinations explicitly disclosed herein. Thus, unless otherwise specified, various features disclosed herein can be combined together to form a number of additional combinations that are not shown for the sake of brevity.
