Abstract
Description
Technical Field
[0001] This application relates to the field of animal experimental technology, specifically to a suction device for animal experiments. Background Technology
[0002] In the field of animal experiments, especially in medical and biological research, it is often necessary to clean the secretions from the airways of experimental animals to prevent airway blockage and death, thus ensuring the smooth progress of experiments and the health of the animals.
[0003] Because small animals such as mice, rats, rabbits, and toads are small, there are currently no suitable devices for suctioning sputum. The main method used is for researchers to use simple tools such as thin cotton swabs and capillary tubes to suction sputum.
[0004] When researchers use thin cotton swabs, capillaries, or other tools to suction sputum, they may encounter problems such as unstable operation, difficulty in suctioning sputum, and insufficient suction volume. Furthermore, they may push sputum and other secretions deeper into the throat, damaging the throat of the experimental animal and, in severe cases, causing the animal to die from hypoxia. Utility Model Content
[0005] The purpose of this application is to provide a suction device for animal experiments, which solves the problem of unstable operation when experimental personnel use hand tools to suction sputum, resulting in unsuccessful sputum suction and small suction volume.
[0006] The technical solution adopted by this application to solve its technical problem is:
[0007] A suction device for animal experiments includes an experimental table and a capillary tube. A support base is provided on one side of the experimental table, and a height-adjustable upright is provided on the support base. A capillary tube connector is provided at the upper end of the upright, and the capillary tube connector is connected to the capillary tube.
[0008] Furthermore, the uprights include folding poles or telescopic poles.
[0009] Furthermore, the capillary connector includes a spring, a silicone ring, an adhesive tape, or a capillary clamp.
[0010] Furthermore, the upper end of the upright is provided with a hook, which is connected to the capillary connector.
[0011] Furthermore, the support base includes a base plate, a top plate disposed above the base plate, and a side plate fixedly connected to the base plate. The side plate is provided with a plurality of fixing holes spaced from top to bottom. One side of the top plate is inserted into one of the fixing holes, and the upright is fixedly connected to the top plate.
[0012] Furthermore, the support base also includes a support column supporting the base plate and the top plate.
[0013] Furthermore, the experimental platform is equipped with several fixing clips.
[0014] Furthermore, the width of the experimental platform is adjustable.
[0015] Furthermore, the experimental platform includes a fixed platform and a movable platform disposed on one side of the fixed platform, the movable platform being able to be close to or away from the fixed platform.
[0016] Furthermore, the experimental platform also includes a replacement platform for being disposed between the fixed platform and the movable platform.
[0017] The beneficial effects of this application are:
[0018] The animal suction device provided in this application is used to suction sputum from experimental animals. During operation, the anesthetized experimental animal is fixed on the experimental table, the capillary tube is connected to the capillary tube connector, and the height of the stand is adjusted to stabilize the capillary tube at a suitable height. The capillary tube uses surface tension to suction sputum from the airway of the experimental animal. Compared with the prior art, it eliminates the need for the experimenter to hold the capillary tube to suction sputum, solving the problem of unstable operation and insufficient sputum suction caused by the experimenter holding the tool to suction sputum. It also avoids damage to the throat of the experimental animal by the capillary tube. Attached Figure Description

[0047] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0048] See Figure 1 This application provides an animal experimental suction device, including an experimental table 1 and a capillary tube 2. A support base 3 is provided on one side of the experimental table 1. A height-adjustable upright rod 4 is provided on the support base 3. A capillary tube connector 5 is provided at the upper end of the upright rod 4. The capillary tube connector 5 is connected to the capillary tube 2.
[0049] Laboratory table 1 provides a specialized operating platform for animal experiments, allowing anesthetized experimental animals to be fixed on the table surface for medical and biological research. Experimental animals may include small animals such as mice, rats, rabbits, and toads, or other small animals; no specific limitations are made here.
[0050] Capillary tube 2 typically refers to a tube with a very small inner diameter that can automatically suction sputum using its surface tension. There are various models of capillary tube 2, and different models are used for suctioning sputum in animals of different sizes, thus broadening the application range of suction devices.
[0051] The support base 3 is set on one side of the experimental table 1 and is used to install and support the upright 4. The upright 4 is set vertically and its lower end is fixedly connected to the support base 3. The upper end of the upright 4 is connected to the capillary connector 5, which is connected to the capillary 2. Thus, the capillary 2 can be stably placed above the experimental table 1, so that the capillary 2 remains stable during suctioning. At the same time, the height of the capillary 2 can be adjusted by adjusting the height of the upright 4.
[0052] The suction device for animal experiments provided in this application embodiment is used to suction sputum from experimental animals. The specific suctioning process is as follows: the anesthetized experimental animal is fixed on the experimental table 1, the capillary tube 2 is connected to the capillary tube connector 5, the position of the support base 3 and the height of the upright 4 are adjusted to stabilize the capillary tube 2 in a suitable position and height, and the lower end of the capillary tube 2 is placed in the sputum in the airway of the experimental animal. The capillary tube 2 uses the surface tension to aspirate the sputum in the airway of the experimental animal.
[0053] Compared with the prior art, the suction device of this application eliminates the need for the experimenter to hold the capillary tube 2 to suction sputum, solving the problem of unstable operation when the experimenter holds the tool to suction sputum, resulting in unsuccessful suction and small suction volume. It also avoids capillary tube damage to the experimental animal's throat, improving the safety of suctioning.
[0054] In some embodiments, see Figure 1 The upright pole 4 may include a folding pole or a telescopic pole.
[0055] A folding rod is a type of support rod that can be folded. It is typically composed of multiple rod segments connected by hinges and locking bolts, and can be folded into different shapes. Utilizing the folding function of the folding rod, not only the height of capillary tube 2 can be adjusted, but also its horizontal position.
[0056] A telescopic rod is a retractable support rod, typically consisting of one or more inner tubes enclosing an outer tube, with its length adjusted by pushing and pulling. Utilizing the telescopic function of the rod, the height of the capillary tube 2 can be adjusted, and by horizontally moving the support base 3, the horizontal position of the capillary tube 2 can be adjusted.
[0057] In some embodiments, see Figure 1 The capillary connector 5 may include a spring. Specifically, the spring is vertically positioned, with its upper end connected to the upper end of the upright rod 4. Since the spring has an inner hole at its center, the capillary 2 can be directly fixed within this inner hole, ensuring stability during suctioning. The size of the spring's inner hole can be the same as or slightly smaller than the outer diameter of the capillary 2, allowing friction to directly fix the capillary 2 within the spring's inner hole. Alternatively, the size of the spring's inner hole can be larger than the outer diameter of the capillary 2, allowing a rubber sleeve to be fitted onto the capillary 2 before fixing it within the spring's inner hole.
[0058] For example, see Figure 3 Springs of various sizes can be set, with the inner diameter of each spring corresponding to the outer diameter of different capillary tubes 2. This allows for the use of different springs to fix different capillary tubes 2, and then to use different capillary tubes 2 to suction sputum from experimental animals of different sizes.
[0059] In other embodiments, the capillary connector 5 may also include a silicone ring, tape, or capillary clamp, as long as it can fix the capillary 2 and keep the capillary 2 stable during suctioning. No specific limitation is made here.
[0060] In some embodiments, see Figure 1 The upper end of the upright 4 is provided with a hook 6, which is connected to the capillary connector 5. Accordingly, by setting the hook 6, the capillary connector 5 can be installed simply by hanging it on the hook 6, which facilitates the quick installation and replacement of the corresponding capillary connector 5 according to the model of the capillary 2.
[0061] In some embodiments, see Figure 2 The support base 3 includes a base plate 31, a top plate 32 disposed above the base plate 31, and a side plate 33 fixedly connected to the base plate 31. The side plate 33 has several fixing holes 321 spaced from top to bottom. One side of the top plate 32 is inserted into one of the fixing holes 321, and the upright 4 is fixedly connected to the top plate 32. Accordingly, by inserting the top plate 32 into fixing holes 321 at different heights, the top plate 32 can be fixed at different heights, thus adjusting the installation height of the upright 4. When the height of the top plate 32 is higher than the tabletop height of the experimental platform 1, the base plate 31 can be moved horizontally to suspend the top plate 32 and the upright 4 above the tabletop of the experimental platform 1.
[0062] In some embodiments, see Figure 2 The support base 3 also includes a support column 34 supported between the base plate 31 and the top plate 32. Accordingly, using the support column 34 to support the base base 31 and the top plate 32 improves the stability and robustness of the support base 3. See also... Figure 4 The support column 34 includes various lengths. When the top plate 32 is inserted into the fixing holes 321 at different heights, support columns 34 of different lengths can be used for support between the bottom plate 31 and the top plate 32. For example, the top of the bottom plate 31 is provided with a bottom plate positioning groove that mates with the lower end of the support column 34, and the bottom of the top plate 32 is provided with a top plate positioning groove that mates with the upper end of the support column 34.
[0063] In some embodiments, see Figure 1 The experimental table 1 has several fixing clips 7 on its surface. For example, there are four fixing clips 7, which are used to fix the limbs of the experimental animal. Accordingly, when the anesthetized experimental animal is placed on the surface of the experimental table 1, the four fixing clips 7 can be used to clamp the limbs of the experimental animal to fix it and prevent the experimental animal from moving during the experiment.
[0064] Of course, in other embodiments, after the anesthetized experimental animal is placed on the table of experimental table 1, the experimental animal can be fixed by other means such as straps, and no specific limitation is made here.
[0065] In some embodiments, the width of the experimental table 1 is adjustable. Accordingly, the adjustable table width can accommodate animals of different sizes and shapes, improving the versatility and flexibility of the experimental table 1.
[0066] In some embodiments, see Figure 5 , Figure 6 The experimental table 1 includes a fixed table 11 and a movable table 12 located on one side of the fixed table 11. The movable table 12 can be moved closer to or further away from the fixed table 11. Accordingly, the movable table 12 can be moved closer to or further away from the fixed table 11 according to experimental needs, which not only makes the spatial layout more flexible and adaptable to the layout requirements of different experiments, but also allows for adjustment of the table surface width of the experimental table 1 to accommodate experiments on animals of different sizes and shapes. In some cases, the movable table 12 can also serve as an additional work area, reducing crowding on the fixed table 11 and lowering the safety risks caused by space congestion.
[0067] Both the fixed platform 11 and the movable platform 12 can be equipped with two fixing clips 7, and the four fixing clips 7 can be used together to fix the limbs of the experimental animal. Of course, both the fixed platform 11 and the movable platform 12 can also be equipped with four fixing clips 7, and no specific limitation is made here.
[0068] For example, the fixed stage 11 and the movable stage 12 are slidably engaged via a slide rail structure 14. The slide rail structure 14 not only reduces friction when the movable stage 12 approaches or moves away from the fixed stage 11, but also provides precise positioning, allowing the movable stage 12 to accurately stop at the desired position, facilitating precise operation by the experimenter. Specifically, the fixed stage 11 has a positioning groove on its side facing the movable stage 12, and the movable stage 12 has a positioning block on its side facing the fixed stage 11 that mates with the positioning groove. When the movable stage 12 approaches the fixed stage 11, the positioning block can be inserted into the positioning groove.
[0069] In some embodiments, see Figure 7 , Figure 8 The experimental platform 1 also includes a replacement platform 13 for placement between the fixed platform 11 and the movable platform 12. Accordingly, the replacement platform 13 can fill the space between the fixed platform 11 and the movable platform 12, so that the fixed platform 11, the replacement platform 13 and the movable platform 12 together form the experimental platform 1, thereby realizing the adjustment of the width of the experimental platform 1.
[0070] For example, the replacement stage 13 may include various width dimensions to flexibly adjust the width of the experimental tabletop according to experimental requirements. During operation, first control the movable stage 12 away from the fixed stage 11, then place the replacement stage 13 of the corresponding size between the movable stage 12 and the fixed stage 11, and then control the movable stage 12 closer to the fixed stage 11 until the replacement stage 13 is clamped, thereby completing the adjustment of the tabletop width of the experimental table 1.
[0071] The suction device for animal experiments provided in this application embodiment can also be used as an animal dissection table in some cases. A lighting lamp can be installed on the upper end of the upright 4 for local illumination, which facilitates the observation of the tissues and organs of the experimental animals.
[0072] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
