A syringe for intramuscular injection of tranexamic acid around the hip joint

technical field

The utility model relates to the technical field of medical equipment, in particular to a syringe for intramuscular injection of tranexamic acid around the hip joint.

Background technique

Hip joint stiffness is prone to reappear after total hip arthroplasty. Once hip joint stiffness occurs, it will cause great damage to patients' daily life and work. Tranexamic acid is an effective hemostatic drug. Due to its anti-fibrinolytic reaction mechanism, it can also play a part in anti-inflammatory and anti-inflammatory effects in surgery and trauma. It is used in hip replacement to reduce wound perioperative effect on period bleeding. The hip joint stiffness after total hip arthroplasty belongs to extra-articular stiffness, and the formation of heterotopic ossification around the joint is the main factor of extra-articular stiffness. Heterotopic ossification is a kind of pathological bone formation. Most studies believe that it is caused by hematoma not being absorbed after formation, and then organized and further calcified to form ossification.

After continuous research and theoretical demonstration, during the treatment of total hip arthroplasty, injection of tranexamic acid into the muscles around the hip joint can prevent the occurrence of heterotopic ossification by reducing local muscle bleeding and reduce the risk of total hip arthroplasty. Hip stiffness recurred after replacement.

Therefore, the present application provides a kind of syringe that is used for the intramuscular injection of tranexamic acid around the hip joint, so that when tranexamic acid is injected intramuscularly around the hip joint, it can reduce the number of punctures to the surrounding muscles and avoid more Local hemorrhage also maximizes the local drug concentration of tranexamic acid in the muscles around the hip joint.

In order to overcome the above-mentioned defects in the prior art, the utility model provides a syringe for intramuscular injection of tranexamic acid around the hip joint, so that when tranexamic acid is injected intramuscularly around the hip joint, it can reduce The number of punctures in the surrounding muscles can avoid more local bleeding, and can also maximize the local drug concentration of tranexamic acid in the muscles around the hip joint.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a syringe for intramuscular injection of tranexamic acid around the hip joint, including a syringe, one end of the syringe is provided with a needle tube, and the syringe is provided with Piston, the end of the piston far away from the syringe is provided with a push rod, the end of the push rod far away from the piston extends out of the syringe, the end of the push rod extending out of the syringe is provided with a push handle, and the outer wall of the end of the syringe near the push handle is provided with an annular stop plate; the end of the needle tube far away from the needle cylinder is provided with a needle point, and the needle point is a bevel; the side wall of the needle tube close to the needle point is provided with opening one, opening two and opening three, and the opening one, opening two and opening three are along the needle tip to the needle cylinder The directions are arranged at intervals in sequence. The connection line of the first opening, the second opening and the third opening is a helical line wound around the wall surface of the needle tube. The projection of the opening direction of the direction and the opening direction of the needle tip on the horizontal plane forms an included angle of 180°, and the projection of the opening direction of opening three and the opening direction of the needle tip on the horizontal plane forms an included angle of 270°.

By adopting the above-mentioned technical scheme, when injecting tranexamic acid, the depth of the needle tip inserted into the hip joint muscle is relatively deep, so that the first opening, the second opening and the third opening can all be submerged in the hip joint muscle of the patient, wherein the needle tip, the first opening, and the second opening The direction of opening 3 is different from that of opening 3, which can maximize the local drug concentration of tranexamic acid in the muscles around the hip joint and reduce the number of punctures.

Further, the outer wall of the syringe is provided with scale lines.

By adopting the above technical solution, the setting of the scale line can facilitate the quantification of the dosage of tranexamic acid by medical personnel.

Further, the first opening, the second opening and the third opening are all elliptical.

By adopting the above-mentioned technical scheme, it is convenient to inject tranexamic acid into the muscles around the hip joint.

Further, the piston is made of rubber.

By adopting the above technical solution, the rubber material is elastic and can closely fit the inner wall of the syringe.

In summary, the utility model has the following beneficial effects: the utility model is simple in structure and strong in practicability, so that when tranexamic acid is injected intramuscularly around the hip joint, the number of punctures to the surrounding muscles can be reduced and more injuries can be avoided. Local hemorrhage also maximizes the local drug concentration of tranexamic acid in the muscles around the hip joint.
