Description
Technical Field
[0001] This utility model belongs to the field of animal experiments, and in particular relates to an animal blood pressure measuring device. Background Technology
[0002] Most laboratory animal diagnoses require blood pressure measurement. Currently, most laboratory animal blood pressure measurement devices on the market have empty tubes. The laboratory animal is directly inserted into the empty tube for measurement, which can easily cause scratches to the laboratory animal. In addition, the air bladder is directly installed on the animal's tail for measurement, which cannot fix the animal's tail. When the animal's tail moves around, the measurement results will be worse. Summary of the Invention

The measuring device also includes a conventional blood pressure measuring sensor and other structures. The first connecting member 134 and the second connecting member 135 form a ring-shaped structure.
[0031] The external fixing unit 1 has an external head clamping groove 15 at one end and an external tail clamping groove 16 at the other end; the internal fixing unit 2 has an internal head clamping groove 26 at one end and an internal tail clamping groove 27 at the other end. If the head cannot be clamped, the tail needs to be clamped.
[0032] The upper part of the outer sleeve 133 has a first limiting hole 1331, and the middle part of the outer sleeve 133 has a second limiting hole 1332. The reset assembly 1310 is located outside the second limiting hole 1332. The top of the limiting rod 138 is provided with a limiting block 1381. The limiting rod 138 cooperates with the first limiting hole 1331 and the second limiting hole 1332 through the limiting block 1381. The reset assembly 1310 cooperates with the limiting rod 138 through the second limiting hole 1332. The outer diameter of the connecting rod 132 is smaller than the outer diameter of the button 131. The limiting rod 138 is located between the button 131 and the connecting spring 139. The inner diameters of the first connecting collar 136 and the second connecting collar 137 are both larger than the outer diameter of the connecting rod 132.
[0033] The reset assembly 1310 includes a reset rod 13101, a reset sleeve 13102, and a reset spring 13103.

The other end of the inner first clamping member 21 is connected to the other end of the inner second clamping member 22 through the inner connecting assembly 23. An inner clamping block 25 is provided on the inner side of both the inner first clamping member 21 and the inner second clamping member 22.
[0035] The structure of the inner connection component 23 is the same as that of the outer connection component 13.
[0036] Implementation process:
[0037] When measuring rats, the outer first clamp 11 and outer second clamp 12 are used for clamping, while the inner first clamp 21 and inner second clamp 22 remain inside them but do not need to be connected, serving a clamping function inside; when measuring mice, the inner first clamp 21 and inner second clamp 22 are used for clamping, and the outer first clamp 11 and outer second clamp 12 do not need to be connected.
[0038] For measuring a mouse, first place the mouse between the inner first clamp 21 and the inner second clamp 22, with the mouse's head in the inner head clamping groove 26 and its tail in the inner tail clamping groove 27. Then, merge the first connecting piece 134 and the second connecting piece 135 into a ring. Then, press down on the button 131. The limiting rod 138 moves downward by the push of the button 131, compressing the connecting spring 139. The limiting block 1381 disengages from the first limiting hole 1331 and moves into the second limiting hole 1332. At this time, the bottom of the connecting rod 132 is positioned... In the second connecting ring, the first clamping member is connected to the inner second clamping member 22 to fix the mouse. After the blood pressure measurement is completed, press the reset rod 13101. The reset rod 13101 moves down and pushes the limiting block 1381, causing it to disengage from the second limiting hole 1332. The limiting rod 138 rises under the action of the connecting spring 139. At this time, the connecting rod 132 moves upward, and the limiting block 1381 re-enters the first limiting hole 1331. The top of the connecting rod 132 leaves the second connecting ring, thus separating the first clamping member from the inner second clamping member 22.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
