Description

Technical Field

[0001] The utility model relates to a constant temperature heater, in particular to a digital display constant temperature heater for an infusion tube with an infrared alarm structure, belonging to the technical field of medical equipment. Background Art

[0002] In the prior art, for example, a utility model with application number 202020441765.X discloses an infusion tube heater. In order to reduce the stimulation of the veins caused by the cold temperature and improve the comfort during infusion, a stepless temperature adjustment handle is provided, and the switch button is pushed to turn on the power. The heating temperature and time are set using the timing switch. Under the action of the torsion spring, the first swing block and the second swing block respectively keep the first hinge and the second hinge stable, and the infusion tube is clamped between the first hinge and the second hinge to heat the liquid. The temperature sensor transmits the temperature to the temperature display. When the temperature is higher than the set temperature, the temperature controller will issue an instruction to stop the electric heater. When the temperature is lower than the set temperature, the temperature controller will issue an instruction to make the electric heater work.

[0003] Similar to the above application, there are still some shortcomings:

[0004] 1. It can only heat the liquid, but cannot give an infusion alarm when the infusion is completed, which reduces the functionality of the device. In addition, it is inconvenient to control the temperature during the infusion process.

[0005] 2. The device is clamped on the infusion tube, which has a certain weight, increases the attachment of the infusion tube, and affects the plug-in stability of the infusion tube joint;

[0006] Therefore, a digital display constant temperature heater for infusion tube with infrared alarm structure is designed to optimize the above problems. Utility Model Content

[0026] like Figure 1-Figure 4 As shown, the present embodiment provides a digital constant temperature heater for an infusion tube with an infrared alarm structure, comprising a shell 1, a cover plate 2 is hingedly mounted on one end of the shell 1, a heating chamber 3 is provided inside the shell 1 along the length direction, a guiding mechanism for the infusion tube is provided inside the heating chamber 3, an electric heating plate 4 is provided at the end of the heating chamber 3, a guide groove 5 is vertically provided at one end of the shell 1 away from the hinge of the cover plate 2, the guide groove 5 is connected to the inside of the heating chamber 3, a temperature sensor 11 is provided at the top and bottom of the inner side of the guide groove 5, a display screen 12 is provided on the cover plate 2, and one side of the top of the guide groove 5 An infrared transmitter 13 is installed, and a receiver 14 is provided at a position on the top of the guide groove 5 corresponding to the infrared transmitter 13. An electric telescopic rod 15 is provided on the outside of the shell 1 and below the infrared transmitter 13, and the output end of the electric telescopic rod 15 extends to the inside of the guide groove 5. A controller 16 is installed below the electric telescopic rod 15, and a buzzer 18 is installed on the outside of the shell 1. The output end of the receiver 14 is electrically connected to the controller 16, and the output end of the controller 16 is electrically connected to the electric telescopic rod 15 and the buzzer 18. A suspension mechanism 17 is provided on the top of the shell 1.

[0027] The overall working principle is as follows: during the installation process, the cover plate 2 is opened, the infusion tube is inserted into the guide groove 5, and the infusion tube passes through the interior of the heating chamber 3 and fits against the outside of the guide mechanism. The guide mechanism is used to control the passing length of the infusion tube in the heating chamber 3, and then the cover plate 2 is covered, and the device is suspended by the suspension mechanism 17. When in use, the temperature sensor 11 detects the temperature of the infusion tube during input and output, and displays the detection result on the display screen 12. In addition, during the infusion process, the infrared ray emitted by the infrared transmitter 13 passes through the interior of the infusion tube. When there is or is no liquid medicine in the infusion tube, the attenuation degree of the infrared ray reaching the receiver 14 is different, that is, the infrared ray intensity received by the receiver 14 is different. When the receiver 14 receives the infrared ray intensity, the controller 16 controls the buzzer 18 to sound an alarm, and controls the electric telescopic rod 15 to extend to squeeze the infusion tube, block the infusion tube, and prevent the continued input of liquid medicine.

[0028] In this embodiment, the guiding mechanism includes a slide groove 6, a slider 7, a screw 8 and an extrusion block 9. The slide groove 6 is opened on the side of the heating bin 3 along the length direction of the heating bin 3. A slider 7 is provided inside the slide groove 6 for sliding along the length direction. An extrusion block 9 is fixedly installed on the slider 7. A screw 8 is rotatably installed between the two ends of the slide groove 6. The screw 8 is threadedly connected to the slider 7, and one end of the screw 8 extends to the outside of the shell 1.

[0029] Local working principle: When the infusion tube passes through the heating chamber 3, it is tightly attached to the outer surface of the extrusion block 9. By controlling the rotation of the screw 8, the extrusion block 9 is driven to slide inside the heating chamber 3 and push the infusion tube toward the inside of the heating chamber 3, thereby changing the path of the infusion tube, increasing the heating time of the medicine, and ensuring the heating effect.

[0030] In this embodiment, the side of the extrusion block 9 close to the electric heating plate 4 is arc-shaped, and the distance between the two ends of the extrusion block 9 and the upper and lower surfaces of the heating chamber 3 is greater than the diameter of the infusion tube.

[0031] Partial working principle: The arc-shaped extrusion block 9 avoids deformation of the infusion tube and ensures the stability of the infusion.

[0032] In this embodiment, an adjusting block 10 is fixedly mounted on one end of the screw rod 8 located outside the housing 1 , and anti-slip grooves are provided on the outside of the adjusting block 10 .

[0033] Partial working principle: When the control screw 8 rotates, the adjusting block 10 is turned by fingers, and the adjustment is more convenient.

[0034] In this embodiment, the suspension mechanism 17 includes a storage box 19, a rotating rod 20, a hanging rope 22 and a positioning screw 24. The storage box 19 is fixed to the top of the outer side of the shell 1. The rotating rod 20 is rotatably installed between the two ends inside the storage box 19. The hanging rope 22 is wrapped around the outer side of the rotating rod 20. One end of the hanging rope 22 extends to the outside of the storage box 19. The side thread of the storage box 19 is threaded with a positioning screw 24.

[0035] Local working principle: After the installation of the shell 1 is completed, the hanging rope 22 is pulled upward, the top of the hanging rope 22 is fixed on the object, the shell 1 is in a suspended state, the pressure caused by the shell 1 on the infusion tube is reduced, and then the positioning screw 24 is tightened to fix the extended length of the hanging rope 22.

[0036] In this embodiment, springs 21 are installed at both ends of the rotating rod 20 , the inner ends of the springs 21 are fixed on the rotating rod 20 , and the outer ends of the springs 21 are fixed on the inner side of the storage box 19 .

[0037] Partial working principle: by using the clockwork spring 21, the hanging rope 22 can be automatically wound around the rotating rod 20 after use, and the storage of the hanging rope 22 is more convenient.

[0038] In this embodiment, a magnet block 23 is fixedly mounted on the top of the hanging rope 22 , and a storage slot is provided on the top of the storage box 19 .

[0039] Partial working principle: The use of the magnet block 23 can be directly adsorbed on the iron object, and the end of the hanging rope 22 is more convenient to fix.
