Description

Technical Field

[0001] The utility model relates to the technical field of experimental anesthesia instruments, in particular to a multi-channel anesthesia device for experimental mice. Background Art

[0002] In some animal surgical experiments, in order to reduce the animals' struggles and keep them quiet for easy operation, necessary anesthesia is often given to the experimental animals. Although experimental animal anesthesia is one of the commonly used methods in medical experiments, achieving accurate anesthesia for experimental animals has always been one of the difficult problems that puzzled researchers. Traditional experimental animal anesthesia mainly involves injecting anesthetics through muscles, abdominal cavity or veins. For example, intramuscular injection of pentobarbital for experimental mice can easily cause problems such as expiratory depression, hypoxia and difficulty in maintaining anesthesia. If the experiment time is too long, anesthetics must be continuously added, and the dosage is not easy to control accurately. In addition, the awakening of injected anesthesia is generally slow. The existing method of inhalation anesthesia for experimental mice is to place a sponge containing the volatile anesthetic ether and the experimental animal in a glass cover, and take out the experimental mouse after the animal is anesthetized.

[0003] With the existing inhalation anesthesia method, due to the differences among individual experimental mice, if multiple experimental mice are placed in a single container for anesthesia at the same time, the unanesthetized individuals are in the process of movement and can easily affect the anesthetized individuals. At the same time, due to the increase in the containing space, additional anesthetic gas is required to achieve anesthesia for all individuals, and the overall anesthesia cost is high. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a multi-channel anesthesia device for experimental mice, which solves the problem that when the existing inhalation anesthesia device anesthetizes multiple experimental mice, the multiple experimental mice are easily interfered with each other and affect the anesthesia effect, and the anesthesia cost is also relatively high.

When the clip portion is clipped to the fixed clip, the other end of the V-shaped plate is in a vertical state, and the experimental mouse can push the V-shaped plate when moving along the secondary channel, so that the clip portion is separated from the fixed clip.

[0010] Preferably, a sealing plate is fixedly connected to the lower end surface of the sealing plate.

[0021] 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.

[0022] See also Figure 1 The utility model provides a technical solution: a multi-channel anesthesia device for experimental mice, comprising a main channel 1, both sides and the end of the main channel 1 are connected with a plurality of side channels 2, the end of the side channel 2 is connected with an anesthetic gas inlet pipe 3, a temporary sealing component is arranged in the inner cavity of the side channel 2, when the experimental mouse moves in the side channel 2, the temporary sealing component can be triggered, the temporary sealing component blocks another experimental mouse from entering the side channel 2 again and makes the side channel 2 in a sealed state, a reset cover 4 and a removal cover 5 are arranged on the upper end surface of the side channel 2, and an attracting component 10 is arranged near the end of the inner cavity of the side channel 2 to attract the experimental mouse to move along the side channel 2.

[0023] The utility model can lure individuals in the experimental mouse group into the secondary channel 2 through the set luring component 10, and in the process of moving, trigger the temporary sealing component to complete the temporary sealing of the secondary channel 2, and then the personnel can pass the anesthetic gas into the single secondary channel 2 through the anesthetic gas inlet pipe 3, so as to complete the anesthesia treatment of the single experimental mouse, and can conveniently and quickly open the removal cover 5 to take out the anesthetized experimental mouse, and at the same time, reset the temporary sealing component by opening the reset cover 4 for the next use. Due to the blocking effect of the temporary limit component, multiple experimental mice can be effectively prevented from entering the same secondary channel 2, ensuring the anesthesia effect for a single individual.

[0024] Reference Figure 3 As shown, in this embodiment, the temporary sealing assembly includes a rotating sealing plate 7 and a plurality of elastic members 8 fixed to the sealing plate 7. The inner cavity of the secondary channel 2 is rotatably connected to the sealing plate 7 through a connecting shaft 6. The end of the elastic member 8 away from the sealing plate 7 is fixedly connected to the cavity wall of the secondary channel 2. The sealing plate 7 is suspended in the inner cavity of the secondary channel 2 through a temporary limiting assembly. When the experimental mouse moves along the secondary channel 2, the temporary limiting assembly 9 can be triggered to release the limiting effect of the sealing plate 7, and then the elastic member 8 drives the sealing plate 7 to reset and complete the blocking and sealing of the secondary channel 2. Through the provision of the temporary limiting assembly 9, when the experimental mouse moves along the secondary channel 2, the temporary limiting assembly 9 can be triggered to release the limiting effect of the sealing plate 7, so that under the elastic reset of the elastic member 8, the sealing plate 7 rotates and then blocks and seals the secondary channel 2, so that a single experimental mouse is independently isolated in the inner cavity of the secondary channel 2, so that subsequent anesthesia treatment can be implemented.

[0025] Reference Figure 4 As shown, in this embodiment, the temporary limit assembly 9 includes a fixed clip 91 fixedly arranged on the sealing plate 7 and a V-shaped plate 92 arranged between the cavity walls of the secondary channel 2 through the connecting shaft 6. A clip portion 93 is arranged at one end of the V-shaped plate 92 close to the sealing plate 7. The clip portion 93 can be clipped with the fixed clip 91. When the clip portion 93 is clipped with the fixed clip 91, the other end of the V-shaped plate 92 is in a vertical state. When the experimental mouse moves along the secondary channel 2, it can push the V-shaped plate 92 to separate the clip portion 93 from the fixed clip 91. When the experimental mouse moves along the secondary channel 2, the V-shaped plate 92 is pushed to rotate during the movement, thereby separating the fixed clip 91 from the clip portion to release the clip connection relationship, so that the elastic member 8 drives the sealing plate 7 to rotate and close the entire secondary channel 2.

[0026] Reference Figure 3 and 4As shown, in this embodiment, a sealing plate 11 is fixedly connected to the lower end surface of the sealing plate 7. When the sealing plate 7 is driven by the elastic member 8 and completes the blocking seal for the secondary channel 2, the sealing plate 11 is deformed and seals the gap between the sealing plate 7 and the lower cavity wall of the secondary channel 2. The sealing plate 11 can improve the sealing performance of the entire secondary channel 2 after the sealing plate 7 seals the secondary channel 2. In actual application, even if there is partial gas leakage in the secondary channel 2, it is only necessary to ensure the sealing performance of one end of the main channel 1 to effectively prevent the anesthetic gas from leaking into the external environment.

[0027] Reference Figure 3 As shown, in this embodiment, the attractant assembly 10 includes a placement base 101 and an attractant disposed on the placement base 101, and the placement base 101 is fixedly disposed in the inner cavity of the secondary channel 2. Since the attractant is attractive to the experimental mouse, the experimental mouse can move along the secondary channel 2, thereby triggering the temporary limit assembly 9, so that the sealing plate 7 can block and isolate a single experimental mouse in a single secondary channel 2 for subsequent anesthesia treatment.

[0028] Reference Figure 3 and 4 As shown, in this embodiment, a shielding sleeve 102 is detachably mounted on the upper portion of the placement base 101, the attractant is located in the inner cavity of the shielding sleeve 102, and a plurality of through holes are provided on the shielding sleeve 102. The shielding sleeve 102 can effectively prevent the experimental mice located in the inner cavity of the secondary channel 2 from directly contacting the attractant, thereby causing unnecessary loss of the attractant, thereby reducing the anesthesia cost for the experimental mice.
