Description

Technical Field

[0001] The utility model relates to the field of experimental animal monitoring equipment, in particular to a multi-channel mouse heart rate and body temperature monitor. Background Art

[0002] In the process of drug development, mouse drug experiments are a crucial link. Through drug experiments on mice, the safety, effectiveness and potential side effects of drugs can be evaluated, providing important data support for subsequent clinical trials. In mouse drug experiments, monitoring the heart rate and body temperature data of mice is of great significance.

[0003] Heart rate and body temperature are important indicators of the physiological state of mice. Changes in heart rate can reflect the effects of drugs on the cardiovascular system, while changes in body temperature may be related to drug metabolism, immune response, etc. Accurately monitoring these data can help researchers better understand the mechanism and effect of drugs.

[0004] The existing monitoring method for the heart rate and body temperature of mice is mainly to record the heart rate data of mice through an electrocardiograph. However, an electrocardiograph can usually only synchronously record the physiological signals of one mouse, and cannot meet the needs of monitoring multiple mice at the same time. If the heart rate and body temperature data of multiple mice need to be recorded, the mice need to be monitored in sequence one after another. The process is cumbersome and time-consuming. If the mouse is in a struggling state, it is more likely to consume time, and the accuracy of the heart rate and body temperature data collected from different mice at similar times is also easily affected. Utility Model Content

[0007] Furthermore, the fastening structure includes a guide seat fixed to the upper surface of each group of limit strips, the inner side of the guide seat is rotatably connected to a pressure rod, and the lower surface of the pressure rod is connected to the limit strip via a pressure spring.

[0009] Furthermore, a pair of limiting protrusions are symmetrically arranged on the inner side of the placing plate. When the placing plate carrying the mouse is moved to the inner side of the channel, the limiting protrusions abut against two legs of the limiting rod.

[0010] Furthermore, the left and right ends of the placement plate are fixedly connected with an alignment plate, the surface of each group of the limit strips is provided with a recessed portion for accommodating the alignment plate, and a pair of pulleys are installed on the lower surface of the alignment plate, and the pulleys are against the inner bottom wall of the channel.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1 A multi-channel mouse heart rate and body temperature monitor shown in the figure includes a rotatable bracket 1, a base 2 installed under the bracket 1 through a bearing, and a plurality of placement plates 3 arranged above the bracket 1. The bracket 1 and the base 2 are coaxially distributed, and the upper surface of the bracket 1 has a plurality of groups of equidistant limit bars 11 symmetrically arranged along a circular trajectory, and the opposite sides of each group of limit bars 11 form a channel.

[0024] As the bracket 1 rotates, multiple placement plates 3 carrying mice can be moved into the inner side of the channel in sequence, and each channel is arranged with a temperature probe 4 that can detect the body temperature of the mouse and a heart rate electrode patch 5 that detects the heart rate. During the monitoring process, the temperature probe 4 above the operation channel is placed on the body of the mouse to measure the body temperature of the mouse. The number of each heart rate electrode patch 5 is two, and the two heart rate electrode patches 5 are operated to fit the front and hind legs of the mouse to measure the heart rate of the mouse. Therefore, above multiple placement plates 3, the heart rate and body temperature of multiple mice can be measured synchronously, which greatly improves the experimental efficiency and data comparability.

[0025] like Figure 5As shown, an adjustable fastening structure is arranged above each set of limit strips 11. When the placement plate 3 carrying the mouse is moved to the inner side of the channel, the fastening structure is located directly above the mouse to prevent the mouse from struggling drastically, making it easier for the temperature probe 4 to make precise contact with the heart rate electrode patch 5 for detecting the heart rate.

[0026] like Figure 2 , Figure 5 As shown, the fastening structure includes a guide seat 12 fixed to the upper surface of each group of limit strips 11, and the inner side of the guide seat 12 is rotatably connected to a pressure rod 13, and the lower surface of the pressure rod 13 is connected to the limit strip 11 through a pressure spring 131. In the natural state, the pressure rod 13 and the limit strip 11 form an angle less than 90 degrees.

[0027] The ends of the pressure rods 13 located above the same channel away from the guide seat 12 are connected by a linkage rod 14, and the surfaces of the linkage rods 14 are fixedly connected with pressure plates 15, the pressure plates 15 face the center position of the bracket 1, and the ends of the pressure plates 15 close to the center position of the bracket 1 are fixedly connected with limiting rods 16, and the limiting rods 16 are distributed in an inverted U shape, with their legs facing the inner side of the placement plate 3.

[0028] When the placement plate 3 carries the mouse and moves to the inner side of the channel, under the elastic potential energy of the pressure spring 131, the pressure rod 13, the pressure rod 13, the linkage rod 14, the pressure plate 15 and the limiting rod 16 are attached to the skin surface of the mouse to suppress the mouse, so as to prevent the mouse from struggling greatly, and facilitate the precise contact between the temperature measuring probe 4 and the heart rate electrode patch 5 for detecting the heart rate. The accuracy of measuring the heart rate and body temperature of the mouse is improved.

[0029] like Figure 3 , Figure 5 As shown, a pair of limiting protrusions 31 are symmetrically arranged on the inner side of the placement plate 3. When the placement plate 3 carrying the mouse is controlled to slide into the inner side of the channel, the pressure rod 13 can be rotated upward to increase the height of the pressure rod 13, the linkage rod 14, the pressure plate 15 and the limiting rod 16. A space is left for the placement plate 3 to smoothly move into the inner side of the channel.

[0030] When the placement board 3 carrying the mouse is moved to the inner side of the channel, the pressure rod 13, the pressure rod 13, the linkage rod 14, the pressure board 15 and the limiting rod 16 are reset under the elastic potential energy of the pressure spring 131, and at this time, the limiting protrusion 31 and the two legs of the limiting rod 16 are against each other. This can effectively prevent the placement board 3 from moving out of the inner side of the channel due to the struggle of the mouse, thereby improving the stability of the placement board 3.

[0031] like Figure 4 , Figure 5As shown, the left and right ends of the placement plate 3 are fixedly connected with alignment plates 32, and the surface of each set of limit strips 11 is provided with a recessed portion that can accommodate the alignment plate 32, and the lower surface of the alignment plate 32 is installed with a pair of pulleys 33, and the pulleys 33 are against the inner bottom wall of the channel. Through the connection between the alignment plate 32 and the limit strips 11, the placement plate 3 can be kept tightly connected with the limit strips 11 after moving into the channel, avoiding the placement plate 3 from shaking left or right on the inner side of the channel. The purpose of adding pulleys 33 is to reduce the friction resistance when the alignment plate 32 is inserted into the inner side of the recessed portion, and to improve the smoothness of the placement plate 3 during the sliding process.

[0032] like Figure 1 As shown, a base 6 is installed at the center of the bracket 1, and a plurality of connecting arms 41 are connected to the side surface and the upper side of the base 6 through a rotating shaft, and the ends of the connecting arms 41 away from the base 6 are rotatably connected to the temperature probe 4. When the placement plate 3 carrying the mouse moves to the inner position of the channel, the connecting arm 41 and the temperature probe 4 can be rotated to ensure that the temperature probe 4 can smoothly contact the mouse skin to measure its body temperature.

[0033] like Figure 3 As shown, a main controller 7 is installed on the upper surface of the base 6, and the temperature probe 4 and the heart rate electrode patch 5 are electrically connected to the main controller 7. The main controller 7 can synchronously record the heart rate and body temperature data of multiple mice when in working state. And the collected data can be uploaded to the analysis software on the computer through the USB communication circuit for management and analysis, so as to facilitate data storage and processing.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
