Description

Technical Field

[0001] This utility model relates to the field of animal experimental technology, specifically to an animal experimental drug administration device. Background Technology

[0002] In livestock farming, animals inevitably fall ill, requiring treatment, and oral medication is a common treatment method. This is especially true for large animals like pigs, whose large size and complex oral structures make oral medication administration relatively difficult. Therefore, specialized medication administration devices are needed to ensure that the medication is accurately and safely administered into the animal's body.

[0003] Currently, in existing technologies, the filling head lacks proper protection, which may lead to leakage of the drug solution during the filling process. This not only affects the accurate delivery of the drug but may also pollute the experimental environment. For some drug solutions that require temperature control, such as high-concentration traditional Chinese medicine solutions, the lack of protection of the filling head may cause the drug solution to lose its suitable temperature before filling, affecting the experimental results. In view of this, we propose a drug filling device for animal experiments. Utility Model Content

[0004] The main objective of this invention is to provide an animal testing drug administration device that can solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention proposes an animal experimental drug delivery device, comprising a power assembly, a support base fixedly connected to the lower part of the power assembly, a control handle slidably connected to the lower part of the power assembly, a drug solution container fixedly connected to the power assembly, the drug solution container being conveyed to a filling head via a delivery pipe, a protective assembly provided on the outer wall of the filling head, and a locking component provided on the protective assembly, the protective assembly comprising:

[0006] A fixed column is fixedly connected to the outer wall of the control handle, and an annular groove is opened on the surface of the fixed column, in which an elastic rope is fixedly connected.

[0007] A fixing rod is fixedly connected to one end of the elastic rope away from the annular groove. A locking block is fixedly connected to the surface of the fixing rod, and the locking block is engaged in the locking groove of the fixing shell. The fixing shell is fixedly connected to the outer wall of the protective shell.

[0008] The protective shell is hinged to a hinge plate, which is hinged in a sliding groove of a hinge rod, and the hinge rod is rotatably connected to the outer wall of the conveying pipe.

[0009] Preferably, the locking component includes a first connecting plate, and the protective shell is provided in two sets. The first connecting plate is fixedly connected to the outer wall of the first set of protective shells, and the surface of the first connecting plate is provided with a through hole. The outer wall of the other set of protective shells is fixedly connected to the second connecting plate. The connection is integrated by connecting the components on the other set of protective shells through the through hole of the first connecting plate.

[0010] Preferably, the surface of the second connecting plate is fixedly connected to the fixed plate, and two sets of limiting rings are fixedly connected to the second connecting plate.

[0011] Preferably, a limiting rod is slidably connected in the through hole and the limiting ring, and a limiting disk is fixedly connected to the outer wall of the limiting rod. During the sliding process of the limiting rod, the limiting disk is limited by the limiting ring to prevent the limiting rod from sliding off-center.

[0012] Preferably, the limiting ring and the fixing ring of the limiting rod are elastically connected by a spring, and a pulling rod is fixedly connected to the fixing ring, which drives the sliding of the fixing ring and the limiting rod.

[0013] Preferably, the pull rod is slidably connected in a through groove in the fixed plate, and the sliding space of the pull rod facilitates the adjustment of the locking and unlocking relationship.

[0014] This invention provides a drug administration device for animal experiments. It has the following beneficial effects:

[0015] (1) The animal experiment drug delivery device has a protective component. When the control handle is manually operated, the elastic rope is pulled backward. The stretching of the elastic rope causes the snap-fit ​​protective shell to unfold. During the unfolding of the protective shell, the hinge plate drives the unfolding of the protective shell. The sliding groove provides the movement space for the deflection of the hinge plate. The filling head can be opened when the drug delivery device is used, thereby reducing drug leakage. After use, the fixing rod is pulled out to release the limit between the locking block and the locking groove. The elastic rope is wrapped in the annular groove and the protective shell is closed to maintain the temperature of the drug.

[0016] (2) The animal experiment drug delivery device has a locking component. When the protective shell is closed, the pull rod is pulled back. The pull rod drives the fixing ring and the limiting rod to slide in a straight line along the through groove of the fixing plate. The spring squeezes and drives the limiting rod to retract until the two sets of protective shells are completely closed. When the pull rod is released, the spring returns to its original position and drives the limiting rod through the through hole of the connecting plate. The two sets of protective shells isolate the filling head from the outside world, prevent drug contamination, and improve the use effect of the subsequent drug delivery device.

The operator injects the drug solution into the target experimental pig by manually operating the control handle 3. A drug solution container 4 is fixedly connected to the power component 1, and the drug solution container 4 is conveyed to the filling head 501 through a delivery pipe 5. A protective component 6 is provided on the outer wall of the filling head 501, and a locking component 7 is provided on the protective component 6. The protective component 6 includes a fixing post 61.

[0030] In this embodiment of the invention, to reduce liquid leakage and control liquid temperature, a fixing post 61 is fixedly connected to the outer wall of the control handle 3, and an annular groove 62 is formed on the surface of the fixing post 61. An elastic rope 63 is fixedly connected in the annular groove 62. When the control handle 3 is manually operated, the elastic rope 63 is pulled backward by force. A fixing rod 64 is fixedly connected to the end of the elastic rope 63 away from the annular groove 62. A locking block 65 is fixedly connected to the surface of the fixing rod 64, and the locking block 65 is engaged in the locking groove 67 of the fixing shell 66. The fixing shell 66 is fixedly connected to the outer wall of the protective shell 68. The stretching of the elastic rope 63 causes the engaged protective shell 68 to unfold, thus opening the fixed... When rod 64 is inserted into fixed housing 66, its locking block 65 automatically engages in locking groove 67, forming a stable connection. When the connection is released, fixed rod 64 is pulled out to release the limiting between locking block 65 and locking groove 67. Protective housing 68 is hinged with hinge plate 69, and hinge plate 69 is hinged in sliding groove 611 of hinge rod 610. Hinge rod 610 is rotatably connected to the outer wall of delivery pipe 5. During the unfolding of protective housing 68, hinge plate 69 drives the unfolding of protective housing 68. Sliding groove 611 provides room for the deflection of hinge plate 69, which can open filling head 501 when using filling device to reduce liquid leakage and control liquid temperature when closed.

[0031] Furthermore, to prevent contamination of the medicine and improve the effectiveness of subsequent dosing devices, the locking assembly 7 specifically includes a connecting plate 71. Two sets of protective shells 68 are provided. The connecting plate 71 is fixedly connected to the outer wall of one set of protective shells 68, and a through hole 72 is provided on the surface of the connecting plate 71. The outer wall of the other set of protective shells 68 is fixedly connected to a connecting plate 73. The connection is achieved by connecting the connecting plate 71 to the assembly on the other set of protective shells 68 through the through hole 72. The surface of the connecting plate 73 is fixedly connected to a fixing plate 74, and a limit ring 75 is fixedly connected to the connecting plate 73. The positioning ring 75 is provided with two sets of limiting rods 77 slidably connected in the through hole 72 and the limiting ring 75. The limiting rod 77 is fixedly connected to the outer wall of the limiting plate 78. During the sliding of the limiting rod 77, the limiting plate 78 is limited by the limiting ring 75 to prevent the limiting rod 77 from sliding off-center. The fixing ring of the limiting ring 75 and the limiting rod 77 is elastically connected by a spring 76. A pull rod 79 is fixedly connected to the fixing ring. The pull rod 79 drives the fixing ring and the limiting rod 77 to slide. The pull rod 79 is slidably connected in the through groove opened in the fixing plate 74. The sliding space of the pull rod 79 facilitates the adjustment of the locking and unlocking relationship.

[0032] In this invention, during use, the operator manually operates the control handle 3 to deliver the liquid medicine through the liquid medicine container 4 and the delivery pipe 5 to the filling head 501, injecting it into the target experimental pig. Simultaneously with manual operation of the control handle 3, the elastic rope 63 is pulled backward, causing the snap-fit ​​protective shell 68 to unfold. During the unfolding of the protective shell 68, the hinge plate 69 also unfolds the protective shell 68. The sliding groove 611 provides space for the deflection of the hinge plate 69, allowing the filling head 501 to be opened when using the dispensing device, thereby reducing liquid medicine leakage. After use, the fixing rod 64 is pulled out to release the lock. The limit between block 65 and slot 67, the elastic rope 63 is wound in the annular groove 62, the protective shell 68 is closed to maintain the temperature of the medicine liquid. When the protective shell 68 is closed, the pull rod 79 is pulled back. The pull rod 79 drives the fixing ring and the limit rod 77 to slide linearly along the through groove of the fixing plate 74. The spring 76 squeezes and drives the limit rod 77 to retract until the two sets of protective shells 68 are completely closed. The pull rod 79 is released, the spring 76 returns to its original position and drives the limit rod 77 through the through hole 72 of the connecting plate 71. The two sets of protective shells 68 isolate the filling head 501 from the outside world, prevent the medicine liquid from being contaminated, and improve the use effect of the subsequent filling device.
