By the adoption of the arm fixing device, the arm of an examined patient can be fixed, the abduction angle of the arm of the patient can be adjusted according to needs, the problem that contrast media are retained in veins due to the fact that the vein blood vessel angle becomes large when the two arms are lifted upwards is solved, and the examination quality is improved.

Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a CT enhanced auxiliary device. Background Art

[0002] For patients undergoing enhanced CT, a conventional indwelling needle is inserted into the median vein of the right elbow, and the contrast agent flows through the subclavian vein into the superior vena cava and finally into the heart. For patients undergoing chest and abdominal examinations, in order to avoid the arms at the side affecting the image quality (the overlap of the arms with the chest and abdomen will produce image artifacts) and thus affect the diagnosis results, medical staff will ask the patients to raise their arms above their heads, so as not to affect the examination quality.

[0003] However, after the arm is raised, due to the change in body position, the angle of the subclavian vein will become larger during enhanced CT, and the contrast agent will often be retained in the vein. The amount of contrast agent that enters the heart cannot achieve the ideal medical effect, thus affecting the examination result. If the patient's arm is abducted and not fixed, most patients cannot persist, affecting the quality of the examination. Utility Model Content

[0028] Example

[0029] Please refer to Figure 1-Figure 4 The present embodiment provides a CT enhancement auxiliary device, including a headrest 1 and two arm restraint plates 2 for restraining arms, the two arm restraint plates 2 are arranged at intervals, and one end of the two arm restraint plates 2 is rotatably arranged on the headrest 1; the headrest 1 is provided with a locking component for locking the arm restraint plates 2 to the headrest 1.

[0030] The arm restraint plate 2 is provided with a plurality of straps 3 at intervals along its extension direction, one end of the strap 3 is fixed to the arm restraint plate 2, and the other end of the strap 3 is a free end. By providing the strap 3, after the patient's arm is placed on the arm restraint plate 2, the patient's arm can be tied to the arm restraint plate 2 through the strap 3.

[0031] In actual use, the CT enhanced auxiliary device is placed on the mobile bed of the CT machine. After the patient lies on the mobile bed of the CT machine, the patient's head is placed on the headrest 1, and the patient's arms are placed on the arm restraint plate 2. Since one end of the arm restraint plate 2 is rotatably arranged on the headrest 1, the arm restraint plate 2 can be rotated as needed to adjust the angle of the patient's arm abduction. After adjustment, the arm restraint plate 2 can be locked to the headrest 1 by the locking component, and the patient's arms can be tied to the arm restraint plate 2 by the strap 3. In this way, the patient can be scanned by CT.

[0032] In this way, the CT enhanced auxiliary device provided in the present application can fix the arm of the patient being examined and adjust the angle of the patient's arm abduction as needed, thereby solving the problem of contrast agent being retained in the veins due to the increase in the angle of the venous vessels caused by raising the arms, thereby improving the quality of the examination.

[0033] like Figure 1-Figure 4 As shown, in some embodiments of the present invention, the cross section of the arm restraint plate 2 is a concave arc, which makes it easier for the patient's arm to be placed in the arm restraint plate 2, thereby facilitating restraining the patient's arm.

[0034] like Figure 1-Figure 4As shown, in some embodiments of the present invention, a connecting rod 4 is provided between the arm restraint plate 2 and the headrest 1, one end of the connecting rod 4 is fixed to the arm restraint plate 2, and the other end of the connecting rod 4 is rotatably provided on the headrest 1. The headrest 1 is provided with a pin shaft 5, and the connecting rod 4 is rotatably provided on the pin shaft 5. By providing the pin shaft 5, it is convenient for the connecting rod 4 and the arm restraint plate 2 to rotate along the headrest 1 as a whole to adjust the angle.

[0035] The locking assembly includes a locking pin 6, a through hole is provided on the connecting rod 4, and a plurality of locking holes 7 are provided at intervals along the rotation direction of the connecting rod 4; the locking pin 6 passes through the through hole and is embedded in the locking hole 7. The locking pin 6 is a bolt, and the locking hole 7 is a screw hole, and the locking pin 6 is threadedly connected to the headrest 1.

[0036] In this way, when the angle of the arm restraint plate 2 needs to be adjusted, the locking pin 6 is rotated to remove it, and then the arm restraint plate 2 can be rotated freely. After the angle of the arm restraint plate 2 is adjusted, the locking pin 6 passes through the through hole and is embedded in the locking hole 7 at the corresponding position, and is connected by threading. In this way, the connecting rod 4 can be fixed to the headrest 1 through the locking pin 6, preventing the arm restraint plate 2 from moving relative to the headrest 1, and improving the stability after fixation. The headrest 1 and the arm restraint plate 2 of this embodiment can be made of materials such as plastic.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments and that the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application.

[0038] Therefore, no matter from which point of view, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present application is limited by the attached claims rather than the above description, so it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims in the present application. Any figure mark in the claims should not be regarded as limiting the claims involved. For those skilled in the art, the utility model can have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
