DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] The utility model provides Figure 1-3The infusion monitoring device shown includes a main shell 100 and a clamping shell 200 arranged on one side of the main shell 100 and capable of translating along the extension direction of the main shell 100. The interior of the main shell 100 is respectively provided with a liquid sensing unit, an MCU and a power supply unit. The power supply unit supplies power, and the liquid sensing unit monitors whether there is liquid medicine transmission in the infusion tube and transmits the signal to the MCU. The MCU analyzes and processes the signal and controls the sound and light alarm 105 to give an alarm prompt. For the specific principle, please refer to a shared infusion alarm disclosed in the authorization announcement number CN215987462U (not described here). A heating switch 103, a monitoring switch 104, and an sound and light alarm 105 are fixedly embedded at the top of the main shell 100. The liquid sensing unit, the power supply unit, the heating switch 103, the monitoring switch 104 and the sound and light alarm 105 are electrically connected to the MCU respectively. A monitoring indicator light 101 and a heating indicator light 102 are fixedly embedded at the top of the main shell 100. The monitoring indicator light 101 and the heating indicator light 102 are electrically connected to the MCU respectively. The switch 103 is used to control the connection between the electric heating rod 301 and the power supply unit, the room version controls the start and stop of the electric heating rod 301, the monitoring switch 104 controls the start and stop of the liquid sensing unit, and the monitoring indicator light 101 and the heating indicator light 102 are convenient for intuitively understanding whether the liquid sensing unit and the electric heating rod 301 are working. The side wall of the main shell 100 is provided with a charging interface 106 electrically connected to the power supply unit, whose main function is to facilitate charging the power supply unit so that it can maintain long-term battery life; the opposite side of the main shell 100 and the clamping shell 200 are A circular arc groove 201 is provided for positioning the infusion tube. A heating structure 300 is provided at positions corresponding to the circular arc groove 201 on the main housing 100 and the clamping housing 200. The heating structure 300 is used to heat the infusion tube. When the circular arc groove 201 is installed with the heating structure 300, the infusion tube can be heated by the heating structure 300 inside the circular arc groove 201 when the circular arc groove 201 clamps the infusion tube. In this way, the liquid medicine can be heated during infusion in cold seasons, making the infusion monitoring device multifunctional and more suitable for diverse usage needs.

[0023] The heating structure 300 includes an electric heating rod 301 and an arc piece 303 fixedly arranged on the inner side of the arc slot 201. The outer wall of the electric heating rod 301 is fixedly sleeved with a connecting kit 302. The connecting kit 302 and the arc piece 303 are both made of heat-conducting materials, and one end of the connecting kit 302 is fixedly connected to the outer wall of the arc piece 303. Heat conduction is carried out through the connecting kit 302, so that the heat generated by the outer wall of the electric heating rod 301 can be transferred to the outer wall of the arc piece 303, thereby heating the outer wall of the infusion tube through the arc piece 303, which not only makes the outer wall of the infusion tube more evenly heated, but also facilitates the installation of the electric heating rod 301 on the main shell 100 and the clamping shell 200. ; Preferably, the connecting kit 302 and the arc piece 303 are both made of copper. The high thermal conductivity of the same material can increase the heat transfer effect and reduce energy loss. The end of the connecting kit 302 corresponding to the electric heating rod 301 is hollow cylindrical, and the length of the connecting kit 302 is less than the length of the arc piece 303, and the length of the arc piece 303 is less than the length of the arc groove 201. In this way, the connecting kit 302 can be installed inside the main shell 100 and the clamping shell 200. At the same time, the length of the arc piece 303 is shorter than the arc groove 201, so that the monitoring end of the liquid sensing unit can be connected to the inner wall of the arc groove 201, which is convenient for directly monitoring whether there is liquid medicine in the infusion tube.

[0024] Furthermore, both ends of the clamping shell 200 facing the main shell 100 are fixedly connected to the connecting rod 400, and both ends of the main shell 100 facing the clamping shell 200 are provided with mounting grooves 107. The outer wall of the connecting rod 400 extends to the inside of the mounting groove 107, and the outer wall of the connecting rod 400 is fixedly connected to a retaining ring 402, and a return spring 401 is fixedly connected between the side wall of the retaining ring 402 and the inner wall of the mounting groove 107. The connecting rod 400 cooperates with the return spring 401 and the retaining ring 402 to enable the clamping shell 200 to elastically reciprocate on one side of the main shell 100, so that after the clamping shell 200 is pulled open and the infusion tube is placed in, the clamping shell 200 can automatically move back to automatically clamp and position the infusion tube, so that the infusion monitoring device can be clamped and hung on the infusion tube. The outer wall of the connecting rod 400; at the same time, a straight through hole 403 is provided in the middle of the connecting rod 400, and a pressing rod 404 is movably inserted in the straight through hole 403, and one end of the pressing rod 404 extends to the outside of the side wall of the main shell 100, and the inner end of the straight through hole 403 is rotatably connected to a hinged connecting rod 405, and the other end of the hinged connecting rod 405 is rotatably connected to the outer wall of the pressing rod 404. When the pressing rod 404 is manually pressed to move, the hinged connecting rod 405 is driven to rotate, so that one end of the hinged connecting rod 405 pushes the connecting rod 400 to extend outward, thereby driving the clamping shell 200 away from the main shell 100. After releasing the pressure on the pressing rod 404, the reset spring 401 can be cooperated to realize the return movement of the clamping shell 200, making the clamping and installation operation of the main shell 100 on the outer wall of the infusion tube more labor-saving and convenient.
