DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] like Figures 1 to 7 As shown, the first embodiment of the present invention provides an animal test drainage tube fixing device, which is used to fix the drainage tube on the animal body during the animal test. The present invention mainly includes a shell 1, a hooking mechanism, a clamping mechanism and a guiding mechanism. Among them, the shell 1 serves as the outer shell of the entire device and provides a basis for the installation of other components. The bottom of the shell has a flat base plate 2. The hooking mechanism includes a plurality of parallel barb units 3, such as Figure 3 As shown, these barb units 3 are movably interspersed on the base plate 2, and can extend out from the bottom of the base plate 2 or retract into the housing 1. The bottom of the barb unit 3 is provided with a fine hook claw, which can be made of Velcro. When the hook claw contacts the hair on the animal's body surface, the complex and staggered barb structure on its surface can hook part of the hair. When the Velcro rubs against the hair, it will also produce an electrostatic adsorption effect, which further improves the ability of the hook claw to drive the hair.

[0037] The clamping mechanism designed in the present invention is used to clamp the hair brought up by the barb unit 3, so that the device can be stably fixed on the hair on the surface of the animal. The clamping mechanism of the present invention is composed of a first clamping part and a second clamping part 5. Figure 2 As shown, the first clamping part includes a first clamping piece 4 whose number and position correspond to the barb unit 3, and the first clamping piece 4 is fixed to the bottom of the substrate 2. The second clamping part 5 is slidably mounted on the substrate 2, and has a plurality of second clamping pieces 6 corresponding to the first clamping pieces 4. When the barb unit 3 extends out of the substrate 2, the barb unit 3 is between the first clamping piece 4 and the second clamping piece 6. When the barb unit 3 hooks the hair and retracts into the housing 1, the barb unit 3 places the hair between the first clamping piece 4 and the second clamping piece 6. When the second clamping part 5 slides to a certain position along the substrate 2, the second clamping piece 6 can press against the first clamping piece 4, thereby tightly clamping the hair hooked by the barb unit 3. This design ensures that the drainage tube fixing device can be stably fixed on the hair on the surface of the animal body and is not easy to loosen and slide off.

[0038] Considering that the drainage tube needs to maintain a certain angle in order to achieve a better drainage effect and reduce the impact on the wound, the drainage tube also needs to be able to adjust a certain angle on the shell 1. Therefore, the present invention designs a guide mechanism on the shell 1 to fix the drainage tube. The guide mechanism of the present invention uses an elastic tube clamp 20, and the tube clamp 20 is installed on the shell 1 through a ball joint support 21. In this way, the tube clamp 20 can use the ball joint support 21 to adjust the angle, so that the angle position of the drainage tube is easier to adjust. The tube clamp 20 can adopt the pipeline restraint structure in the prior art, such as a hoop. The present invention also threadedly installs a locking bolt 22 on the ball joint support 21 to fix the angle of the tube clamp 20 on the ball joint support 21, thereby ensuring that the drainage tube can be accurately positioned according to the test requirements.

[0039] Embodiment 2:

[0040] On the basis of the first embodiment, in order to facilitate operation, the present invention fixes all the barb units 3 on an integration plate 7, so as to control all the barb units 3 to extend out of the base plate 2 by driving the integration plate 7 to move. An adjustment mechanism is provided on the housing 1 to drive the integration plate 7 to move along the length direction of the barb units 3.

[0041] like Figure 3 As shown, the adjustment mechanism of the present invention specifically includes components such as a guide rod 8, a drive block 9, a limit frame 11, a slider 12, and a spring 13. The guide rod 8 is movably plugged into the housing 1 and is perpendicular to the moving direction of the hook unit 3. The drive block 9 is fixed to one end of the guide rod 8 located in the housing 1, and an inclined drive slot 10 is provided on the guide rod 8. The spring 13 is sleeved on the guide rod 8 between the drive block 9 and the housing 1. Figure 7 As shown, the limit frame 11 is fixed on the side of the integration plate 7 away from the barb unit 3, and a slider 12 that slidably cooperates with the driving groove 10 is fixed on the limit frame 11. Figure 5 As shown in the figure, when the driving block 9 is pushed to compress the spring 13, the driving slot 10 forces the slider 12 to move downward, so that the integration plate 7 and the barb unit 3 move along their length direction (i.e. downward). When the driving block 9 is released, under the action of the spring 13, the driving block 9 can lift the slider 12 again, so that the barb unit 3 is retracted into the housing 1.

[0042] In order to allow the spring 13 to make the second clamp 6 press against the first clamp 4, a baffle 14 is fixed on the second clamping portion 5 of the present invention, and the baffle 14 is located on the side of the driving block 9 away from the spring 13. Figure 3 As shown, when the spring 13 is in the natural state, the driving block 9 will push the baffle 14 to make the second clamping portion 5 slide on the substrate 2, thereby keeping the second clamping piece 6 in a state of being pressed against the first clamping piece 4. When the barb unit 3 needs to extend out of the substrate 2, the second clamping piece 6 needs to make way for the barb unit 3. For this purpose, the second clamping portion 5 of the present invention is fixed with a making way block 15 that cooperates with the slider 12. Figure 5 As viewed from the reference point, when the slider 12 moves toward the substrate 2 , the inclined surface of the slider 12 pushes the stop block 15 to move rightward, thereby moving the second clamp 6 away from the first clamp 4 , allowing the barb unit 3 to extend from between the first clamp 4 and the second clamp 6 .

[0043] Embodiment three:

[0044] Based on the above embodiments, Figure 5As shown, in order to facilitate operation, the present invention fixes a first pressing portion 16 and a second pressing portion 17 on the housing 1 and the driving block 9, respectively, so that the user can pinch the first pressing portion 16 and the second pressing portion 17 with one hand to control the movement of the driving block 9. In addition, in order to enhance the clamping effect, a groove 18 is provided on the first clamping piece 4, and a convex ridge 19 matching the groove 18 is provided on the second clamping piece 6. The hair is clamped by the convex ridge 19 and the groove 18, which further increases the resistance to hair pulling out and improves the stability and reliability when clamping the hair.

[0045] When in use, the user only needs to pinch the first pressing part 16 and the second pressing part 17 with one hand to push the driving block 9 to compress the spring 13, so that the driving block 9 pushes the slider 12 to move, and the slider 12 pushes the second clamping part 5 in the direction away from the first clamp 4, so that the second clamp 6 is separated from the first clamp 4, and the movement of the slider 12 will also cause the barb unit 3 to extend from between the second clamp 6 and the first clamp 4. Then the user rubs the bottom of the barb unit 3 on the hair on the surface of the animal body, so that the barb unit 3 fully attracts and hooks the hair. Then the user releases the first pressing part 16 and the second pressing part 17, and the driving block 9 is reset under the action of the spring 13, so that the barb unit 3 retracts into the housing 1, and at the same time pulls the hair between the first clamp 4 and the second clamp 6, and then the driving block 9 will push the baffle 14, so that the second clamp 6 moves toward the first clamp 4, and the hair is pressed tightly between the first clamp 4 and the second clamp 6, and the device is fixed to the hair on the surface of the animal body. Then fix the drainage tube on the tube clamp 20, adjust the angle of the tube clamp 20, complete the adjustment of the angle of the drainage tube, and tighten the locking bolt 22 to fix the angle of the drainage tube, so that the drainage tube can be stably fixed on the animal body surface.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
