[0023] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described below are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0024] Reference Figure 1-Figure 5 A thermocouple for measuring the temperature of mice includes a thermocouple body connection end 1, an auxiliary end 5 is fixedly connected to one side of the thermocouple body connection end 1, a thermocouple pin 9 is fixedly connected to one side of the thermocouple body connection end 1, a connection end 10 is fixedly connected to one side of the thermocouple pin 9, a thermocouple wire 7 is fixedly connected to one side of the connection end 10, and the thermocouple wire 7 includes two metal wires. The outer ring surfaces of the two horizontally arranged thermocouple wires 7 are bonded to form an auxiliary wire 4, which is a thermocouple. The thermocouple wire is bent to form a fixed knot 3, and a fixed hole is formed inside the fixed knot 3. The thermocouple wire 7 can also be bent into an arc shape. The outer ring surfaces of the non-arc-shaped parts of the two thermocouple wires 7 are bonded together. The two thermocouple wires 7 can be twisted into a spiral shape, and the thermocouple wire 7 is electrically connected to the thermocouple pin 9.
[0025] Specifically, the auxiliary end 5 can be used to assist the use of the thermocouple body connection end 1, and the connection end 10 can assist the connection between the end of the thermocouple pin 9 and the thermocouple wire 7, avoiding the connection between one end of the thermocouple wire 7 and the thermocouple pin 9. The thermocouple pin 9 and the connection end 10 can realize the electrical connection between the thermocouple body connection end 1 and the thermocouple wire 7, thereby ensuring the circuit connectivity inside the thermocouple body connection end 1, so that the thermocouple body connection end 1 can be used normally. The multiple fixing knots 3 made by the auxiliary wire 4 can form a corresponding number of fixing holes, and the fixing holes can be used to guide the installation of the suture, and the contact between the auxiliary suture and the mouse skin can be achieved through the spiral gap and the ring made of arc symmetry, so that the auxiliary wire 4 fits the mouse skin and reduces the looseness of the auxiliary wire 4 during use.
[0026] As an optimization solution, Figure 1-Figure 5As shown, a fixing block 6 is bonded to the bottom of the thermocouple body connection end 1, and the fixing block 6 is penetrated by the thermocouple pin 9. A protective net 2 is bonded to one side of the fixing block 6. The protective net 2 is in a grid shape, and the through hole on the protective net 2 is penetrated by the thermocouple pin 9. A fixing block 2 8 is bonded to one side of the protective net 2, and one side of the fixing block 2 8 is fixedly connected to the connection end 10.
[0027] Specifically, the fixing block 1 6 can be used to support the bottom of the thermocouple body connection end 1, assisting in the initial connection between the bottom of the thermocouple body connection end 1 and the protective net 2. The fixing block 2 8 can be used to reinforce the connection between the thermocouple pin 9 and the connection end 10, and can also improve the stability of the connection between the connection end 10 and the thermocouple wire 7, and reduce the looseness of the connection at the thermocouple wire 7. Since a number of through holes are provided on the protective net 2, the glue on the protective net 2 and the fixing block 1 6 can pass through the protective net 2, realizing the connection between the fixing block 1 6 and the fixing block 2 8, so that the fixing block 2 8 can be used to reinforce the thermocouple body connection end 1 again, reducing the shaking of the thermocouple body connection end 1 during use.
[0028] Working principle: First, pass the two thermocouple pins 9 at the bottom of the thermocouple body connection end 1 through the protective net 2, then weld one end of the thermocouple wire 7 to the connection end 10, and then use glue to bond them on both sides of the protective net 2 to form a fixing block 1 6 and a fixing block 2 8, to limit and fix the thermocouple body connection end 1 and the connection end 10. When the two thermocouple wires 7 are horizontally distributed to make auxiliary wires 4, the auxiliary wires 4 can be overlapped to make a fixing knot 3, and the suture is passed through the fixing hole on the fixing knot 3 and fixed to the mouse skin to achieve the fixation of the thermocouple, or the two thermocouple wires 7 are twisted into a spiral. At this time, the fixation of the thermocouple wire 7 and the thermocouple can be achieved through the gap directly in the spiral. When the two thermocouple wires 7 are bent into an arc, the suture can be passed through the circular ring surrounded by the arcs on both sides to bind the thermocouple wire 7 to the mouse, so that the thermocouple wire 7 can move synchronously with the mouse, thereby achieving stable installation and use of the thermocouple body connection end 1, facilitating accurate measurement of the mouse body temperature through the thermocouple body connection end 1.
