Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit fly anesthesia technology, specifically a fruit fly anesthesia device. Background Technology
[0002] In the field of biological research, fruit flies are widely used as a classic model organism in research on genetics, developmental biology, neurobiology and many other fields. Anesthetizing fruit flies is an indispensable part of many experimental steps and plays a vital role in the smooth progress of subsequent experimental steps.
[0003] Traditional methods of anesthetizing fruit flies typically involve transferring them from their culture bottles to another empty bottle for anesthesia. The transfer between different containers requires a high degree of alignment between the bottle openings, demanding a high level of skill and expertise from the operator. Operations such as "removing the stopper" and "closing the bottle" during the transfer process, as well as gaps caused by misalignment of the bottle openings, can all lead to the fruit flies escaping during the transfer, increasing the uncertainty of fruit fly anesthesia.
[0004] Therefore, this utility model proposes a fruit fly anesthesia device to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a fruit fly anesthesia device to solve the above-mentioned problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A fruit fly anesthesia device includes a cylinder, a cylinder cap, a positioning mechanism, and a cap removal mechanism. During the anesthesia operation, the fruit fly culture bottle is placed in the cylinder, the positioning mechanism is used to position the fruit fly culture bottle, and the cap removal mechanism is used to remove the cap of the fruit fly culture bottle.
[0008] The positioning mechanism includes at least three first clamping members evenly arranged circumferentially in the cylinder and telescopic members corresponding to the first clamping members one by one. The telescopic end of the telescopic member is fixedly connected to the corresponding first clamping member.
[0009] The cap removal mechanism includes a guide cylinder passing through the cap, a sealing piston disposed in the guide cylinder, and a first operating rod passing through the sealing piston. The lower end of the first operating rod is provided with a slide rail, and two second clamping members for clamping the cap of the culture bottle are slidably engaged on the slide rail. The midpoint of the line connecting the two second clamping members is coaxial with the center point of the plurality of first clamping members.
[0010] In one alternative: both the first clamping member and the second clamping member have adhesive pads attached to their clamping sides.
[0011] In one alternative: a pressure sensor for real-time sensing of clamping pressure is provided between the telescopic end of the first clamping member and the first clamping member.
[0012] In one alternative embodiment: a bidirectional lead screw is rotatably mounted on the slide rail, and two segments of the bidirectional lead screw with opposite thread directions pass through two second clamping members in a threaded engagement manner. The first operating rod is hollow and tubular, and a second operating rod is inserted through the first operating rod. A sealed bearing is provided between the second operating rod and the first operating rod, and a first bevel gear is provided at the lower end of the second operating rod. A second bevel gear that meshes with the first bevel gear is provided on the bidirectional lead screw.
[0013] In one alternative: the cylinder is provided with a drug tray for placing anesthetic agents for evaporation, and the cylinder wall is provided with a drug injection port.
[0014] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows:
[0015] Open the tube lid, place the fruit fly culture bottle inside the tube and position it using the positioning mechanism, then replace the tube lid. Next, remove the cap from the fruit fly culture bottle using the cap removal mechanism, and the fruit flies will fly out of the bottle opening. Then, add an appropriate amount of anesthetic to the tube. The fruit flies will be anesthetized by the evaporation of the anesthetic. The operation is simple and convenient, effectively solving the problem of fruit flies easily flying out and escaping during transfer operations, and ensuring the smooth progress of fruit fly anesthesia.

Detailed Implementation
[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0024] Please see Figure 1 A fruit fly anesthesia device includes a cylinder 1, a cylinder cap 2, a positioning mechanism 3, and a cap removal mechanism 4. During the anesthesia operation, the fruit fly culture bottle is placed in the cylinder 1. The positioning mechanism 3 is used to position the fruit fly culture bottle, and the cap removal mechanism 4 is used to remove the cap of the fruit fly culture bottle.
[0025] It should be noted that the cap 2 is adapted to the body 1, and the connection between the cap 2 and the body 1 can be achieved by means of threaded connection, snap-fit connection, etc. This application does not limit the connection. When the cap 2 is assembled on the body 1, the body 1 is in a sealed state, thereby preventing the anesthetic from evaporating and leaking to the outside of the device. In addition, the body 1 is made of transparent material, such as acrylic material, PC material, etc., so that the operator can directly observe the anesthetized state of the fruit flies through the wall of the body 1.
[0026] Open the cap 2, place the fruit fly culture bottle into the cylinder 1 and position it using the positioning mechanism 3, then reassemble the cap 2. Next, remove the cap from the fruit fly culture bottle using the cap removal mechanism 4. The fruit flies will fly out of the bottle opening. Then, add an appropriate amount of anesthetic (such as ether) into the cylinder 1. The fruit flies will be anesthetized by the evaporation of the anesthetic. The operation is simple and convenient, effectively solving the problem of fruit flies easily flying out and escaping during transfer operations, ensuring the smooth progress of fruit fly anesthesia. It should be further noted that after all the fruit flies have flown out, the cap is closed onto the bottle body using the cap removal mechanism 4, and then the anesthetic is added into the cylinder 1. The cap seals the bottle, preventing the evaporating anesthetic from entering the culture bottle and remaining, which would affect subsequent use.
[0027] Furthermore, the cylinder 1 is provided with a drug tray 5 for placing anesthetic agents for evaporation, and the cylinder wall of the cylinder 1 is provided with a drug injection port 6. The drug injection port 6 is provided with corresponding sealing measures, such as a sealing cap or valve. When adding drugs, the drug injection port 6 is opened to add an appropriate amount of anesthetic agent to the drug tray 5 for evaporation. After the drug addition is completed, the drug injection port 6 is closed.
[0028] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the positioning mechanism 3 includes at least three first clamping members 301 evenly arranged in the cylinder 1 in the circumferential direction and telescopic members 302 corresponding to the first clamping members 301. The telescopic end of the telescopic member 302 is fixedly connected to the corresponding first clamping member 301. Preferably, the telescopic member 302 is an electric telescopic rod.
[0029] A pressure sensor 303 for real-time sensing of clamping pressure is provided between the telescopic end of the first clamping member 301 and the first clamping member 301. The pressure sensor 303 is model DSHW-108.
[0030] In this embodiment, the fruit fly culture bottle is placed between multiple first clamping members 301, and then multiple telescopic members 302 are controlled to extend synchronously, causing the first clamping members 301 to move synchronously closer to the fruit fly culture bottle until the fruit fly culture bottle is clamped and positioned. The clamping pressure is sensed in real time by the pressure sensor 303. When the pressure sensor 303 senses that the clamping pressure reaches the set value, the telescopic member 302 automatically stops extending and retracting, indicating that the fruit fly culture bottle has been clamped in place (i.e., the fruit fly culture bottle is centered). It should be noted that the anesthesia device also includes a corresponding processing control unit (not shown in the figure). The processing control unit receives the signal feedback from the pressure sensor 303 in real time and controls the telescopic member 302 to make corresponding actions, realizing the linkage between the telescopic member 302 and the pressure sensor 303. The corresponding processing control technology is existing technology and will not be described in detail here. In addition, in this embodiment, the fruit fly anesthesia device also includes a control panel for controlling the extension and retraction of the telescopic member 302 and a power supply for powering the electrical components in the anesthesia device (not shown in the figure).
[0031] Furthermore, in this embodiment, the first clamping member 301 has an adhesive pad attached to its clamping side to provide clamping protection and prevent damage such as clamping marks from being left on the bottle.
[0032] Please see Figure 1 , Figure 3 and Figure 4In one embodiment of this utility model, the cap removal mechanism 4 includes a guide cylinder 401 passing through the cap 2, a sealing piston 406 disposed in the guide cylinder 401, and a first operating rod 404 passing through the sealing piston 406. A slide rail 402 is provided at the lower end of the first operating rod 404. Two second clamping members 403 for clamping the cap of the culture bottle are slidably engaged on the slide rail 402. A bidirectional lead screw 409 is also rotatably disposed on the slide rail 402. The two segments of the bidirectional lead screw 409 with opposite thread directions are respectively threaded... The two second clamping members 403 are connected in a manner that allows them to pass through each other. The midpoint of the line connecting the two second clamping members 403 is coaxial with the center point of the multiple first clamping members 301. The first operating rod 404 is hollow and a second operating rod 405 is inserted through it. A sealed bearing 407 is provided between the second operating rod 405 and the first operating rod 404. A first bevel gear 408 is provided at the lower end of the second operating rod 405. A second bevel gear 410 that meshes with the first bevel gear 408 is provided on the bidirectional lead screw 409.
[0033] In this embodiment, after the fruit fly culture bottle is centered, the first operating lever 404 is pushed downwards, causing the two second clamping members 403 to move downwards accordingly until the height is reached to clamp the culture bottle cap. Then, by rotating the second operating lever 405, the bidirectional lead screw 409 is rotated, which in turn causes the two second clamping members 403 to move synchronously closer to the culture bottle cap until the culture bottle cap is clamped. Next, the operation is performed according to the fit between the culture bottle cap and the bottle body. If the cap and the bottle body are threaded, the first operating lever 404 is rotated, causing the slide rail 402 to rotate as a whole, that is, causing the two second clamping members 403 to revolve and unscrew the cap. After unscrewing, the first... The operating lever 404 can be moved upward a certain distance; if the bottle cap and bottle body adopt a pull-out type fit, the first operating lever 404 can be pulled upward directly by hand; it should be noted that the sealing piston 406 can simultaneously meet the needs of the first operating lever 404 to move up and down and rotate, and the squeezing force between the sealing piston 406 and the inner wall of the guide cylinder 401 can play a certain positioning role, so that when the operator's hand is removed from the first operating lever 404, the first operating lever 404, the slide rail 402, the two second clamping parts 403 and the clamped culture bottle cap and other components will not move downward due to gravity; in addition, the sealing piston 406 and the sealing bearing 407 are used to seal and prevent the anesthetic agent from evaporating and leaking to the outside of the device.
[0034] Furthermore, in this embodiment, the second clamping member 403 is also provided with an adhesive pad on its clamping side, which also serves as a clamping and protective measure to prevent damage such as clamping marks from being left on the bottle cap.
[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
