Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a portable stem cell injection device. Background Technology

[0002] As people's living standards continue to improve, the number of pet owners is gradually increasing, and people are paying more and more attention to their pets. However, if pets are not properly cared for, they can easily become ill. In the veterinary field, stem cell therapy can effectively improve the quality of life for animals and help them overcome illness.

[0003] Stem cells are immature tissue precursor cells with the ability to self-renew, form clonal cell populations, and differentiate into multiple pluripotent cells. Stem cell therapy is used to regenerate and repair damaged tissues and organs and rebuild their function after acute or chronic injuries. Stem cell injection via epidural puncture in pets can be used for cell transplantation therapy for spinal cord injuries. During epidural injection, the needle should be inserted between the lumbar vertebrae or L7-S1 to puncture the skin. After strict sterilization, the bevel of the needle should face the tail, and the spinal cord should be inserted perpendicularly to the skin at a 90-degree angle. The needle should puncture the skin, subcutaneous tissue, supraspinous ligament, intervertebral ligament, and ligamentum flavum in sequence before entering the epidural space, where the medication is gently injected.

[0004] When administering epidural injections into the spinal cord, dogs or cats must be strictly restrained to prevent them from suddenly moving due to fright during the injection process. Therefore, an additional staff member is required to restrain the pet during the injection to facilitate the injection procedure. It is difficult to perform the injection alone. In addition, when dogs or cats are frightened and suddenly move, it is often difficult for one staff member to maintain strict restraint, which can easily lead to injection deviation and serious spinal cord damage. Therefore, there is an urgent need to design a portable stem cell injection device to solve the above problems. Summary of the Invention

[0005] This invention provides a portable stem cell injection device with a reasonable structural design to solve the technical problems existing in the prior art. This invention can securely fix the pet, ensure precise positioning of the syringe for injection and perpendicular insertion into the skin at a 90-degree angle, and prevent syringe deviation.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A portable stem cell injection device includes a central saddle-shaped seat, with a clamp seat one pivotally connected to one end of the central saddle-shaped seat and a clamp seat two pivotally connected to the other end. The pivot positions of the central saddle-shaped seat and the clamp seat one, as well as the pivot positions of the central saddle-shaped seat and the clamp seat two, are adjustable. A positioning groove two is provided on the clamp seat one, and an adjustable seat plate two, whose position in the axial direction of the clamp seat one is adjustable, is provided at the positioning groove two. An adjusting screw two is screwed onto the adjustable seat plate two.

[0027] Working principle: In the actual work process, the pet is placed on the treatment table 24, and then the splint seat 1 and splint seat 2 13 are placed on the pet's torso and locked to the treatment table 24 respectively; then the adjusting screw 15 and adjusting screw 22 are rotated respectively, thereby driving the corresponding positioning splint 2 11 and positioning splint 4 to move toward the pet's torso until the pet is pressed on the treatment table 24, thereby restraining the pet's torso and preventing the pet from moving around and affecting the subsequent injection operation; After completing the above restraint operation, the position of the intermediate saddle seat 16 can be adjusted according to the site of the drug to be injected, that is, the position of the movable pivot block 15 relative to the clamp seat 1 and the position of the movable pivot block 28 relative to the clamp seat 23 can be adjusted so that the operating slide plate 18 installed on the intermediate saddle seat 16 can be directly facing the site of the pet to be injected. Then, the position of the operating slide plate 18 in the circumferential direction of the intermediate saddle seat 16 is adjusted, and the position of the operating slide plate 18 is locked by the bolt passing through the end face locking hole 17. After the above adjustments are completed, the syringe 20 can be used to inject drugs into the pet's epidural space. In actual operation, the injection mounting component 19 ensures the stable installation of the syringe 20. With the cooperation of the operating slide plate 18 and the injection mounting component 19, the syringe 20 can always be perpendicular to the pet's skin at a 90-degree angle. When performing the injection, push the moving guide block 19-8 along the guide strip hole 19-6, so that the outer sleeve 19-9 compresses the support spring 19-4, and at the same time, drive the syringe 20 to move towards the pet until the tip of the syringe 20 is perpendicular to the pet's skin at a 90-degree angle. Then push the syringe 20 to push the drug in the syringe 20 into the pet's body. After the injection is completed, the elastic limiting claw 19-10 can be pried outward to release the positioning pressure on the syringe 20, so that the syringe 20 can be ejected under the action of the support spring 19-5, which facilitates the next injection operation.
