Description

Technical Field

[0001] This utility model relates to the technical field of animal experiments, and in particular to an experimental device for rat drug metabolism kinetic surgery. Background Technology

[0002] In animal experiments, one type of experiment is the rat pharmacokinetic study, which involves measuring the concentration of the drug in the blood at different time points after administration to understand how the drug is metabolized in the body. Commonly, rats are used as experimental animals to dynamically collect blood, urine, and bile samples from multiple sites according to pharmacokinetic requirements. This requires a specialized operating table to facilitate dissection and experimentation.

[0003] Patent application 202322579245.1 discloses an experimental operating table for mice, comprising an operating table and a restraint device for securing experimental mice to the table surface. The operating table includes a tabletop with its upper and lower surfaces forming the table surface. The tabletop is supported by a height-adjustable support mechanism. An operating window is provided on the tabletop. After the experimental mouse is restrained to one side of the tabletop with restraint straps, the tabletop is flipped over, exposing the mouse's tissue through the operating window for surgical experiments. This novel operating table facilitates surgical experiments by allowing the tissue of the experimental mouse restrained on the opposite tabletop to be exposed through the window on the tabletop.

[0004] However, such operating tables are mainly used for collecting hematuria from mice, and the effect on bile collection is not ideal. This is because the lack of supplemental lighting affects the visual effect and leads to an increase in experimental error. At the same time, the lack of bile duct fixation device makes it unsuitable for bile collection from mice, and improvements are urgently needed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a rat operating table for bile collection experiments. The operating table facilitates the bile tube insertion operation by adding a lighting device and a centrifuge tube fixator, and ensures the stability of the centrifuge tube when receiving bile.

[0006] In view of the above, the present invention provides the following technical solution:

[0007] A rat operating table for bile collection experiments includes a lower support and an upper operating table.

[0008] The lower support mainly consists of a base plate and a support device. The support device is fixedly connected to the base plate and extends upward to support the upper operating table, ensuring the stability of the entire device.

[0009] The support device supports a lighting device via a pole. The lighting device is higher than the upper operating table to illuminate the operating table.

[0010] The upper part of the support device is the upper operating table, which includes an operating table angle adjustment module and a surgical plate. The support device supports the operating table angle adjustment module, which includes two semicircular rings and a positioning bolt. The two semicircular rings are slidable and fixedly connected to the surgical plate, and the positioning bolt is used for positioning. The angle of the surgical plate can be adjusted and fixed through the operating table angle adjustment module.

[0011] The surgical board includes a rectangular platform with fixing clips at the four corners for securing the limbs of small animals. Two centrifuge tube holders are designed in the lower middle part of the platform, symmetrically arranged on the left and right, and fixedly connected to the side of the platform and slightly higher than the surface of the surgical platform. The extra distance allows for the placement of centrifuge tubes.

[0012] This invention improves the smooth progress of rat pharmacokinetic surgery by adding a lighting device and providing sufficient light source. At the same time, fixing the centrifuge tube between two freely movable bolts ensures the stability of the centrifuge tube during bile collection.

[0013] Furthermore, the support device is a telescopic column with fastening bolts for fixing the telescopic column after height adjustment. In this way, the lower part of the cylindrical support device can freely extend and retract, and the height of the bracket can be fixed using the bolts on the right side after adjustment to a suitable height.

[0014] Furthermore, the lighting device is an LED light, which is positioned above the upper operating table. The lamp head uses a low-wattage yellow LED light source to protect the eyes of the experimenters during prolonged operation.

[0015] Furthermore, the pole is a flexible plastic tube, which is fixedly connected to the lighting device. Since the flexible plastic tube can be changed at any angle and shape, it is convenient for the experimenter to adjust the position of the light source at any time according to the situation.

[0016] Furthermore, the LED lamp has a lamp tube, a light switch, and a battery compartment. The light switch is located on the left side of the lamp tube for easy control. The battery compartment, which provides power, is located at the top of the lamp tube for easy battery replacement. Even if the power is exhausted during the experiment, the battery can be replaced in time to ensure the experiment can continue.

[0017] Furthermore, a constant temperature heating pad is also laid on the platform. The constant temperature heating pad is electrically connected to the power supply to keep the rat's body temperature constant during the experiment, reduce the animal mortality rate, and ensure that experiments requiring long-term anesthesia can be carried out smoothly.

[0018] Furthermore, the constant temperature heating pad is fixed to the operating table with clamps around its perimeter. When the experiment does not require the heating pad or the cleaning device needs to be installed, the clamps can be loosened and the heating pad removed at any time. The clamps around the perimeter are fixed to the table with bolts, and the clamps have movable bolts for fixing the rat's limbs. Therefore, the experimenter can use cotton rope to wrap around the bolts to fix the rat, and can flexibly adjust the bolts according to the size of the animal to find the most suitable fixation position.

[0019] As can be seen from the above technical solutions, the embodiments of this utility model have the following advantages:

[0020] 1. The rat operating table for bile collection experiments implemented in this utility model, by adding a lighting device, provides sufficient light source, which is conducive to the smooth performance of rat drug metabolism kinetic surgery and also makes the surgery more precise.

[0021] 2. The rat operating table for bile collection experiments implemented by this utility model, by setting a centrifuge tube fixator, facilitates the experimenter's bile tube insertion operation and ensures the stability of the centrifuge tube when receiving bile.

[0022] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0027] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0028] The following describes in detail, with reference to the accompanying drawings, a rat operating table for bile collection experiments according to an embodiment of the present invention.

[0029] For easier understanding, please refer to Figure 1-Figure 2 This invention provides a rat operating table for bile collection experiments, comprising a lower support and an upper operating table.

[0030] The lower support is mainly divided into a base plate 1 and a support device 2. The support device 2 is fixedly connected to the base plate 1 and extends upward to support the upper operating table to ensure the stability of the entire device.

[0031] The support device 2 is a telescopic column, which is equipped with fastening bolts 3 for fixing the telescopic column after height adjustment. In this way, the lower part of the cylindrical support device can extend and retract freely, and the height of the bracket can be fixed using the bolts on the right side after adjustment to a suitable height.

[0032] The support device 2 supports the lighting device 5 via the upright 4. The lighting device 5 is higher than the upper operating table 6 to illuminate the operating table.

[0033] The lighting device is an LED light, which is positioned above the upper operating table. The light source uses a low-wattage yellow LED to protect the eyes of the experimenters during prolonged operation.

[0034] The support pole 4 is a flexible plastic tube, which is fixedly connected to the lighting device. Because the flexible plastic tube can be changed at any angle and shape, it is convenient for the experimenter to adjust the position of the light source at any time according to the situation.

[0035] Specifically, the LED lamp has a lamp tube 51, a light switch 52, and a battery compartment 53. The light switch 52 is located on the left side of the LED lamp tube 51 for easy control. The battery compartment 53, which provides power, is located at the top of the LED lamp tube and contains a battery. The location of the battery compartment 53 makes it easy to replace the battery, so that even if the power is exhausted during the experiment, the battery can be replaced in time to ensure the experiment can continue.

[0036] The upper part of the support device is the upper operating table, which includes an operating table angle adjustment module 7 and a surgical plate 6. The support device 2 supports the operating table angle adjustment module 7, which includes two semicircular rings and positioning bolts. The two semicircular rings are slidable and fixedly connected to the surgical plate, and are positioned by the positioning bolts. The angle of the surgical plate can be adjusted and fixed by the operating table angle adjustment module.

[0037] The operating table is fixed to the rat operating board by two sliding semicircular rings. Therefore, the operator can adjust the tilt angle of the rat operating table at will by providing the semicircular rings. After adjusting to the optimal angle for the experiment, the positioning bolts can be tightened to fix the rat operating table.

[0038] The surgical board 6 includes a rectangular platform 61. Fixing clips 63 are provided at the four corners of the platform 61 for fixing the limbs of small animals. Normally, the fixing clips 63 are fixed to the platform 61 with bolts. The lower part of the platform 61 is designed with two centrifuge tube holders 65. The two centrifuge tube holders 65 are symmetrical. In order to make the structure more stable, the centrifuge tube holders 65 are fixedly connected to the side of the platform 61 by fasteners 66, and then bent to the surface of the platform 61, slightly higher than the surface of the platform. The extra distance can meet the placement of centrifuge tubes.

[0039] A constant temperature heating pad 62 is also laid on the platform 61. The constant temperature heating pad 62 is electrically connected to the power supply to keep the rat's body temperature constant during the experiment, reduce the animal mortality rate, and ensure that experiments requiring long-term anesthesia can be carried out smoothly.

[0040] The constant temperature heating pad 62 is fixed to the operating table by clamps 63. When the experiment does not require the heating pad or the cleaning device is needed, the clamps 63 can be loosened and the constant temperature heating pad 62 can be removed at any time. The clamps 62 are fixedly connected to the table 61 by bolts 64. At the same time, the middle of the clamps 63 is provided with a groove 67, and can also be provided with movable bolts for fixing the rat's limbs. The movable bolts are set in the grooves 67, so the experimenter can use cotton rope to fix the rat around the bolts, and can flexibly adjust the bolts according to the size of the animal to find the most suitable fixation position.

[0041] To prevent the centrifuge tubes collecting bile from shifting during the experiment, which could lead to dislodgement or spillage due to tilting, two centrifuge tube holders are designed symmetrically on the lower part of the operating table. These holders are fixed to the side of the table and slightly higher than the surface, allowing for proper placement of the centrifuge tubes. Once the experimenters determine the correct placement of the centrifuge tubes within the holders, they can be secured between two freely movable bolts, ensuring stability during bile collection.

[0042] In summary, this invention facilitates the smooth conduct of rat pharmacokinetic surgery by adding a lighting device and providing sufficient light source. At the same time, fixing the centrifuge tube between two freely movable bolts ensures the stability of the centrifuge tube during bile collection.

[0043] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
