Description

Technical Field

[0001] The utility model relates to the technical field of gas anesthesia, in particular to a gas anesthesia system of a photoacoustic ultrasound imaging device for small animals. Background Art

[0002] Small animal photoacoustic ultrasound imaging equipment is a medical device used for non-invasive image diagnosis of small animals. It combines optical imaging and ultrasound imaging technology. A short pulse laser beam is sent into the animal's body through a laser light source. When the laser interacts with the tissue, a photoacoustic effect is generated. The generated ultrasonic signal is then received by an ultrasound probe, and an image is generated after processing and analysis. Before performing photoacoustic ultrasound imaging on small animals, it is usually necessary to use an anesthesia machine to anesthetize the small animal to keep it quiet.

[0003] Since the mask at the front end of the gas anesthesia machine pipeline lacks a head fixation design, in actual operation, the heads of small animals (small rodents) are directly pushed into the mask without any fixation. During animal experiments, the heads are easily detached from the mask. If the animals are slightly awake, they are likely to break free from the mask, resulting in failure of the experiment.

[0004] In view of the above problems, the present utility model document proposes a small animal photoacoustic ultrasound imaging device anesthesia system. Utility Model Content

Under the limiting action of the first limiting block, the second limiting block and the limiting slide groove, the rack is translated to cause the tooth rod to shrink into the regulating frame until the head of the mouse is tightened and completely embedded in the mask, effectively avoiding the failure of the experiment caused by the mouse escaping from the mask during the animal experiment, and the use is convenient;

[0018] Then start the gas anesthesia machine to deliver anesthetic gas to anesthetize the mice. After the experiment is completed, start the micro vacuum pump to recover the waste gas remaining in the anesthesia pipeline into the waste gas collection tank through the first hose and the second hose to avoid waste gas leakage.

[0032] The output end of the anesthesia pipeline 1 is connected to the input end of the regulating frame 2 by a threaded connection. This connection method not only ensures the firmness of the connection, but also facilitates disassembly and cleaning when necessary. The anesthetic gas is transported to the regulating frame 2 through the anesthesia pipeline 1, and then acts on the face of the small animal through the mask 3;

[0033] An adjustable fixing component is provided inside the regulating frame 2, which is used to fix the head of the small animal, and the tightness of the fixation can be adjusted according to the experimental requirements. Specifically, the adjustable fixing component includes a tooth rod 4, one end of which extends into the mask 3 and is fixedly provided with a hook ring 5. The hook ring 5 can firmly hook the teeth of the small animal to ensure that the head of the small animal remains fixed during the imaging process. The top and one side of the tooth rod 4 are respectively fixedly provided with a second limit block 7 and a first limit block 6. The inner wall of the regulating frame 2 is provided with a corresponding limit slide groove 8. By sliding the second limit block 7 and the first limit block 6 in the limit slide groove 8, the position of the tooth rod 4 can be conveniently adjusted, thereby achieving fine adjustment of the fixed position of the small animal's head;

[0034] In order to achieve precise control of the position of the tooth rod 4, the present application has a rack 11 fixedly arranged on one side of the tooth rod 4, and a threaded rod 9 is threadedly connected to the top of the regulating frame 2. The bottom end of the threaded rod 9 passes through the top of the inner wall of the regulating frame 2 and is rotatably connected to the bottom of the inner wall of the regulating frame 2. A gear 12 is fixedly arranged on the threaded rod 9, and the gear 12 is meshed with the rack 11. By rotating the threaded rod 9, the gear 12 can be driven to rotate, and then the rack 11 can be driven to move, thereby achieving precise adjustment of the position of the tooth rod 4. In order to facilitate user operation, the top end of the threaded rod 9 passes through the top of the outer wall of the regulating frame 2 and is fixedly arranged with a screw cap 10. The screw cap 10 is provided with multiple anti-slip convex pieces in a ring array to increase friction and prevent hand slippage;

[0035] In addition, the present application also provides a waste gas recovery component for recovering waste gas in the anesthesia pipeline 1 after the test. The waste gas recovery component includes a micro-vacuum pump 14 and a waste gas collection tank 16. The micro-vacuum pump 14 is connected to an external power supply through an external switch and powered on. The model is Hailin D08. The output end of the micro-vacuum pump 14 is connected to the inner wall of the anesthesia pipeline 1 through a first hose 13. The output end of the micro-vacuum pump 14 is connected to the inner wall of the waste gas collection tank 16 through a second hose 15. After the test, the micro-vacuum pump 14 is started, and the waste gas in the anesthesia pipeline 1 can be sucked into the micro-vacuum pump 14 through the first hose 13, and then discharged into the waste gas collection tank 16 through the second hose 15, so as to realize the recovery and treatment of the waste gas.
