Description

Technical Field

[0001] The utility model relates to the technical field of injection beds, in particular to an injection auxiliary device and an injection bed. Background Art

[0002] In the field of medical care, intravenous drip beds, as a common medical device, are widely used in hospitals, clinics and home care to provide patients with a comfortable infusion environment. For example, the intravenous drip bed disclosed in the technical solution of Patent No. 202323302033.5, the existing intravenous drip bed usually includes a main bed board and auxiliary bed boards connected to both ends of the main bed board. These auxiliary bed boards are usually driven by telescopic cylinders and can be adjusted in angle relative to the main bed board to adapt to the lying needs of different patients and improve the flexibility and comfort of care. At the same time, in order to facilitate the infusion operation, a hanging shaft is usually rotatably installed on the side wall of the main bed board. The hanging shaft is provided with a hanging slot for hanging an infusion bottle or an infusion bag. The hanging shaft can be rotated relative to the main bed board so that the hanging shaft can be laid flat when not in use to avoid obstruction to the activities of medical staff and patients.

[0003] However, while this technical solution improves the practicality of the IV bed to a certain extent, the length of the hanging shaft is fixed. When the hanging shaft is erected to suspend an infusion bottle or bag, the hanging height it can provide is fixed. This fixed height design may not be suitable for all situations, as different infusion bottles or bags vary in size and weight, and factors such as the patient's height and body position may also affect the optimal hanging height. Therefore, in actual use, medical staff may need to adjust the IV stand or other auxiliary equipment to adapt to different infusion needs, which undoubtedly increases the complexity and inconvenience of operation.

[0029] Furthermore, one end of the second straight rod 3 is telescopically and slidably connected to the other end of the first straight rod 2, and the second straight rod 3 is provided with a telescopic locking structure for buckling on the first straight rod 2 to limit the fitting length between the first straight rod 2 and the second straight rod 3. The other end of the second straight rod 3 is provided with a hanging part 5 for hanging an infusion bottle and an infusion bag, and the hanging part 5 can be folded relative to the second straight rod 3. The second straight rod 3 is provided with a state maintaining structure for limiting the folding angle and the unfolding angle of the hanging part 5.

[0030] The present invention utilizes a telescopic rod with a retractable length as the main structure of the injection assist device, allowing medical personnel to conveniently adjust the length of the telescopic rod based on factors such as the patient's height, body position, and the size and weight of the infusion bottle or bag, thereby finding the optimal hanging height. This not only improves the convenience of infusion operations but also helps optimize the patient's infusion experience and reduces discomfort caused by improper hanging height. Furthermore, when the injection assist device is not in use, medical personnel can retract the telescopic rod to its minimum length and fold up the telescopic rod and hanging member 5, thereby reducing the space occupied by the entire injection assist device.
