Description

Technical Field

[0001] This utility model belongs to the field of pet medical supplies technology, and in particular relates to a long-term drug delivery device for canine and feline stem cell factors in bone and joint. Background Technology

[0002] Osteoarthritis is based on acute or chronic damage to the articular cartilage or degeneration of the articular cartilage. In the veterinary field, osteoarthritis mostly occurs in older animals (including pets) or animals with bone injuries that are difficult to heal, and requires the use of cytokines or stem cells for combined treatment.

[0003] The treatment process involves injecting medication into the animal's knee joint or performing surgery followed by immobilization. After a certain period, the joint is opened, and the medical effects or physiological changes in the knee joint are assessed to determine the effectiveness of the treatment. Currently, there is a lack of a device to assist veterinarians in immobilizing the joint during drug injection treatment. This often requires an additional staff member to stabilize the joint, facilitating drug administration and preventing the animal from bending and affecting the injection. Therefore, it is difficult for a staff member to perform the injection alone. Thus, there is an urgent need to design a long-term bone and joint drug delivery device for canine and feline stem cell factors to solve these problems. Utility Model Content

[0004] This invention provides a long-term bone and joint drug delivery device for canine and feline stem cell factors with a reasonable structural design to solve the technical problems existing in the prior art. This invention can fix the limbs on both sides of the joint in dogs / cats, preventing the joint from bending during drug injection. It eliminates the need for additional personnel to perform limb fixation operations and allows for precise positioning of the injection site, making it highly versatile.

[0005] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A long-term drug delivery device for canine and feline stem cell factors in bone and joints includes a semi-circular intermediate positioning member. A saddle-shaped upper clamping plate is pivotally connected to one end of the intermediate positioning member, and a saddle-shaped upper clamping plate is pivotally connected to the other end. The position of the pivot connection between the intermediate positioning member and the upper clamping plate is adjustable. A saddle-shaped lower clamping plate is bolted to the upper clamping plate, and a saddle-shaped lower clamping plate is bolted to the upper clamping plate. A device located between the lower clamping plate and the lower clamping plate is installed on the lower clamping plate. The system includes an intermediate supporting arc plate; a positioning arc plate that can move circumferentially and is position-adjustable is installed on the intermediate positioning component; a through hole is opened in the middle of the positioning arc plate and a drug delivery positioning sleeve is installed at the through hole; multiple threaded sleeves that are fixedly connected to the positioning arc plate are provided around the drug delivery positioning sleeve; a pressing positioning mechanism that penetrates the positioning arc plate is screwed onto each threaded sleeve; a positioning support is installed on the upper clamping plate 2; an elastic pushing component that is elastically connected to the upper clamping plate 1 is installed on the positioning support; and an inner clamping arc plate is installed on the inner arc surfaces of the upper clamping plate 1 and the lower clamping plate 1, as well as the inner arc surfaces of the upper clamping plate 2 and the lower clamping plate 2, by means of several springs.

[0006] The advantages and positive effects of this utility model are as follows: This utility model provides a long-term drug delivery device for canine and feline stem cell factors in bone and joints. The device uses two upper and two lower clamps, as well as one upper clamp and one lower clamp, to fix the limbs on both sides of the joint of a dog / cat. This ensures that the intermediate positioning component is directly opposite the joint, preventing joint bending from affecting subsequent drug injection. Multiple pressing and positioning mechanisms can press down on the joint, preventing joint bending during drug injection. Furthermore, the pivot position of the intermediate positioning component and the upper clamp is adjustable, and the elastic pushing component can push the lower clamp away from the fixed position. The directional movement of the support allows for fine-tuning of the relative positions of the intermediate positioning component and the upper clamp plate during joint fixation, based on individual differences in dogs / cats. Furthermore, the adjustable position of the positioning arc plate in the circumferential direction of the intermediate positioning component ensures that the drug delivery positioning sleeve installed on the positioning arc plate is directly aligned with the drug injection site at the joint, guaranteeing precise injection location and improving the device's applicability. This invention can fix the limbs on both sides of a dog / cat's joint, preventing bending during drug injection. It eliminates the need for additional personnel to perform limb fixation and allows for precise injection positioning, making it highly versatile.

[0028] Working principle:

[0029] In actual operation, the upper clamp 2 8 and lower clamp 2 10, as well as the upper clamp 1 and lower clamp 15, installed together can be used to fix the limbs on both sides of the dog / cat's joint, so that the middle positioning piece 6 is directly opposite the joint, avoiding joint bending that would affect subsequent drug injection operations; drive the positioning arc plate 5 to slide in the adjustment groove 13, so that the drug delivery positioning sleeve 4 is directly opposite the drug injection position at the joint, and then lock the position of the positioning arc plate 5. Before drug injection, rotate the pressing screw 2 to move the pressing pad 14, thereby pressing the joint and preventing the dog / cat from bending its joint during drug injection;

[0030] Since the pivot position of the intermediate positioning member 6 and the upper clamping plate 2 8 is adjustable, and the elastic pushing component 17 can push the lower clamping plate 15 to move away from the positioning support 9, the relative position of the intermediate positioning member 6 and the upper clamping plate 2 8 can be finely adjusted according to the individual differences of dogs / cats during the joint fixing process, thereby ensuring that the drug delivery positioning sleeve 4 is aligned with the drug injection position at the joint, thus improving the applicability of the device.
