[0014] Preferably, the outer wall of the mounting post is rotatably connected to the inner wall of the housing, and the outer wall of the mounting post is fixedly connected to a rotating disk.
[0015] Working principle: First, perform comprehensive sterilization 24 hours in advance. The operating table, floor, and tabletop need to be cleaned with new benzalkonium chloride, and the room needs to be irradiated with ultraviolet light; the second step is to sterilize and disinfect surgical instruments, surgical clothing, and other auxiliary equipment in advance and place them in the operating room or locker room. The third step is to fast the animal overnight one day in advance; the fourth step is to prepare insulation measures, such as insulation pads and room heating, to prevent the animal from hypothermia during surgery and before awakening after surgery. The fifth step is to anesthetize the animal: the anesthetic preparation uses atropine + Shutai 50, which can be adjusted according to the animal's condition. Adjust the dosage of anesthetic preparations according to the state. The sixth step is disinfection: disinfect with iodine-containing disinfectant, and then use 75% alcohol to deiodine. The seventh step is to lay a sterile pad and make an incision on the inner thigh of the animal. Use a puncture sleeve to puncture subcutaneously to the appropriate part of the back. The eighth step is to separate the muscles at the inner thigh incision and find the femoral vein. The ninth step is to insert the heparin-filled internal catheter into the vein 30cm, and pass the other end through the built passage to the back. The tenth step is to suture the muscle layer and skin. Finally, connect the equipment: the animal wears a special vest and The catheter in the dog's body passes through the opening of the vest and is connected to the bottom end of the three-way valve. One end of the infusion extension tube is connected to the other port of the three-way valve, and the other end of the infusion extension tube is connected to the injection pump. By setting the injection parameters of the injection pump to control the rate, time and volume of the infusion, the animal can be continuously infused for a long time and multiple times in a waking state. Then, by rotating the rotating disk, the rotating disk will drive the installation column to rotate, the installation column will drive the rotating plate to rotate, and the rotating plate will drive the rotating column to slide. The rotating column will slide under the action of the sliding plate, and the sliding plate will slide on the inner wall of the sliding groove. When the rotating column slides, the spring will be compressed. When the rotating plate rotates to the top of the rotating column, the push column will be fixed to prevent the push column from rebounding. When the rotating plate rotates to the inner wall of the rotating column, the spring will be stretched. When the spring stretches, the push column will be contracted. Finally, the push column will squeeze the infusion extension tube to the inner wall of the card slot, so that when the manual fine-tuning is completed, the operator can lock the fine-tuning device to avoid accidentally changing the infusion speed, which causes the dog to feel uncomfortable due to the influence of the infusion speed.
[0016] The present invention provides a model device for continuous infusion of canines. It has the following beneficial effects: 1. The present invention allows the animal to wear a special vest, and passes the catheter in the dog's body through the opening of the vest and connects it to the bottom end of the three-way valve. One end of the infusion extension tube is connected to the other port of the three-way valve, and the other end of the infusion extension tube is connected to the injection pump. By setting the injection parameters of the injection pump to control the rate, time and volume of the infusion, the animal can be continuously infused for a long time and multiple times in a conscious state, so that the animal can move freely in a conscious state without affecting eating and drinking, which meets the requirements of animal welfare.
[0017] 2. The present invention makes an incision on the inner thigh of the animal, uses a puncture sleeve to puncture subcutaneously to a suitable place on the back, separates the muscles at the inner thigh incision, finds the femoral vein, inserts an in vivo catheter filled with heparin into the vein 30 cm, and passes the other end through an established passage to the back, sutures the muscle layer and the skin, and does not require continuous human attention during the infusion process, does not require continuous human restraint of the animal, and reduces manpower and material resources.
[0018] 3. The present invention allows the animal to wear a special vest, and the catheter in the dog's body is passed through the opening of the vest and connected to the bottom end of the three-way valve, one end of the infusion extension tube is connected to the other end of the three-way valve, and the other end of the infusion extension tube is connected to the injection pump, so as to improve the success rate and accuracy of the infusion, and more time can be used to observe the changes in the dog's condition, formulate treatment plans and perform other nursing work, thereby improving work efficiency.
[0019] 4. Due to the presence of the three-way valve, when an animal develops symptoms such as allergies during the infusion process, the corresponding medicine can be injected at one end of the three-way valve to provide timely treatment and avoid accidents to the animal.
[0020] 5. The present invention manually rotates the rotating disk, which drives the push column to move, so that after the manual fine-tuning is completed, the operator can lock the fine-tuning device to avoid accidental changes in the infusion speed, which may cause the dog to feel uncomfortable due to the influence of the infusion speed.
