Description

Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a rat feces cleaning and collecting device. Background Art

[0002] During animal experiments, feces and urine are often collected for laboratory testing. Laboratory rats are currently the most widely used experimental animals. Usually, a feces collection device is used to directly enter the rat's body, which can easily irritate the rat, causing sampling failure and making sampling more difficult. Alternatively, the rat is placed in a metabolic cage to collect feces, but the feces excreted by the rat has difficulty falling into the collection box, resulting in cross-infection between the feces and other bacteria. After collection, the workload of cleaning and disinfecting the feces is relatively large.

[0003] In order to solve the above problems, a Chinese patent (patent publication number CN218587904U) discloses a simple mouse defecation collection device, including a mouse plate and a box cover. A defecation collection opening is opened on the right side of the top of the mouse plate, and four limb positioning columns are fixedly installed on both sides of the top of the mouse plate, and the outer surfaces of the eight limb positioning columns are wrapped with limb fastening belts; a tail placement opening is opened at the lower left side of the box cover, and a tail positioning column is fixedly installed on the left side of the box cover, and the outer surface of the tail positioning column is wrapped with a rear tail fastening belt.

[0004] The above scheme secures the limbs and tail of the experimental mouse by tying them up, and positions the hind limbs and the anus of the experimental mouse above the fecal collection opening, so that the feces of the experimental mouse can fall accurately into the interior of the sterile box after defecation, thereby preventing the feces from being contaminated by other bacteria and achieving the purpose of aseptic feces collection. However, when tying the experimental mouse, the tightness of the tie cannot be adjusted at any time. When the tie is too loose or too tight, it will affect sampling when the experimental mouse is stimulated. In addition, the body shapes of the experimental mice are different, making it difficult to control the tightness of the tie when tying them. Utility Model Content

[0005] The utility model is intended to provide a rat cleaning and excrement collection device to solve the problem in the above background technology that the tightness of the rat binding cannot be adjusted at any time.

[0008] The principle of the technical solution: through the combination of a frame and an iron frame, the support column on the frame can slide through the connecting block, the rat is placed on the iron frame, and the rat's limbs are fixed with straps through the support column. After fixation, the tightness of the binding can be adjusted by sliding the support column, so that the rat can move slightly, align the rat's anus with the defecation opening, and then stimulate the rat to defecate, so that the feces fall accurately into the defecation collection component.

[0009] Preferably, the groove is rotatably connected to a screw rod, the screw rod is provided with a left thread segment and a right thread segment, the left thread segment and the right thread segment of the screw rod are respectively connected to a connecting block, and the right end of the screw rod is provided with a rotating head.

[0010] Through the above setting, the connecting block can be controlled to slide left and right by rotating the rotating head, so that the support column on the connecting block can move left and right, which can facilitate the fixation of the limbs of rats of different sizes. After the limbs of the rat are fixed, the tightness of the limb fixation can be adjusted by sliding and rotating the rotating head, so as to facilitate the control of the rat for sampling.

[0011] Preferably, the defecation collection assembly includes a bottom box and a defecation collection box, the bottom box is fixedly connected below the defecation collection port, a slide groove is provided on the bottom box, a convex strip is provided on the defecation collection box, the convex strip is slidably connected to the slide groove, and a handle is provided on the defecation collection box.

[0012] Through the above arrangement, the rats are stimulated to excrete feces into the feces collection box, and then the handle is pulled to remove the feces collection box from the bottom box, so that the feces can be taken out conveniently and quickly, and the feces are prevented from contaminating other places and being contaminated.

[0013] Preferably, a boss is provided in the defecation box, and a filter is placed on the boss.

[0014] Through the above arrangement, when the rat is stimulated to defecate, the feces discharged by the rat will fall into the filter net, and the corresponding urine will flow through the filter net and fall to the bottom of the feces collection box, thereby realizing the separation and collection of feces and urine.

[0015] Preferably, a U-shaped extension plate is provided on the base box.

[0016] Through the above-mentioned setting, when stimulating rats to defecate, the corresponding excrement can be prevented from splashing to other places and causing pollution, and the rat's excrement can be effectively and accurately dropped into the defecation box.

[0017] Preferably, the U-shaped plate is provided with a through hole, and the frame is provided with a support column corresponding to the through hole.

[0018] With the above arrangement, the rat's tail can be passed through the through hole and fixed on the support column, thereby preventing the rat's tail from moving around when the rat is stimulated. BRIEF DESCRIPTION OF THE DRAWINGS
