Technical Field
The utility model relates to the technical field of medical equipment, in particular to an injector for intramuscular injection of tranexamic acid around a hip joint.
Background
Hip stiffness is easily reappeared after total hip replacement, and once the hip stiffness occurs, the daily life and work of a patient are greatly damaged. Tranexamic acid is an effective hemostatic drug, and can also play a part of anti-inflammatory and detumescence roles in operations and wounds due to an anti-fibrinolytic reaction mechanism, and is applied to hip joint replacement operation to reduce the curative effect of bleeding in the wound peri-operation period. Hip joint stiffness occurring after total hip arthroplasty belongs to extra-articular stiffness, and the formation of periarticular ectopic ossification is a major factor of the extra-articular stiffness. Ectopic ossification is a pathological bone formation that is most probably due to the formation of hematomas that are not absorbed and are organized and further calcified to form ossification.
After continuous research and theoretical demonstration, in the treatment process of total hip arthroplasty, tranexamic acid injection is carried out on muscles around the hip joint, and by reducing local muscle bleeding, ectopic ossification can be prevented, and hip joint stiffness is reduced again after total hip arthroplasty.
Therefore, the injector for injecting the tranexamic acid into the muscles around the hip joint is provided, so that the puncture times of the tranexamic acid to the muscles around the hip joint can be reduced, more local bleeding can be avoided, and the local medicine concentration of the tranexamic acid in the muscles around the hip joint can be diffused to the greatest extent.

By adopting the technical scheme, when tranexamic acid is injected, the needle tip is inserted into the hip joint muscle to a deeper depth, so that the first opening, the second opening and the third opening can be submerged into the hip joint muscle of a patient, wherein the directions of the needle tip, the first opening, the second opening and the third opening are different, the local medicine concentration of tranexamic acid in the surrounding muscle of the hip joint can be diffused to the greatest extent, and the puncture times are reduced.
Further, the outer wall of the needle cylinder is provided with scale marks.
By adopting the technical scheme, the setting of scale mark can be convenient for medical personnel to quantify the dosage of tranexamic acid.
Further, the first opening, the second opening and the third opening are all elliptical.
By adopting the technical scheme, the tranexamic acid is convenient to be injected into muscles around the hip joint.
Further, the piston is made of rubber.
By adopting the technical scheme, the rubber material has elasticity and can be tightly attached to the inner wall of the needle cylinder.
In summary, the utility model has the following beneficial effects: the utility model has simple structure and strong practicability, can reduce the puncture times to surrounding muscles when the tranexamic acid is injected into the surrounding muscles of the hip joint, avoid more local bleeding, and can maximally diffuse the local medicine concentration of the tranexamic acid in the surrounding muscles of the hip joint.
