Puncture bed for children

Abstract

The invention discloses a puncture bed for children. The puncture bed comprises a bed board horizontally arranged left and right, a bed frame arranged on the outer side of the bed board and supporting legs installed at the lower end of the bed frame. A through hole for fixing a child is formed in the upper end of the bed board, a U-shaped pull belt penetrating downwards is installed in the through hole, an anti-falling tray abutting against the upper side of the bed board is arranged at the upper end of the pull belt, a bandage mechanism for fixing the body of the child is installed at the upper end of the tray, and the other end of the pull belt is connected with elastic cloth installed at the lower end of the side, close to the bed frame, of the bed frame and used for providing elastic tension. The puncture bed further comprises a guide mechanism arranged at the lower ends of the pull belt and the bed board and used for keeping the pull belt in a U shape, and a speed control mechanism capable of being clamped and fixed when the pull belt is rapidly pulled is arranged between the pull belt and the elastic cloth. When the child twists by a large margin, the pull belt rapidly moves and drives a guide plate to move downwards, and due to the inertia effect, a clamping plate and the guide plate are promoted to move relatively, and the clamping plate turns over and is clamped between protruding edges.

Description

technical field [0001] The invention relates to the field of puncture beds for children, in particular to a puncture bed for children. Background technique [0002] For bone marrow aspiration examination, considering the safety of the operation and the success rate of puncture, the posterior superior iliac crest of the child is usually selected as the puncture point, which requires the patient to have a fixed position, and the prone position is often chosen. Children have their own characteristics, and children often have fear. Psychological and unable to cooperate, thereby increasing the difficulty of puncture and reducing the success rate of puncture. For bone marrow puncture in children, at least two or more medical staff are required to fix the child, expose the puncture point of the posterior superior iliac crest, the operating doctor will perform the puncture, and another doctor will perform the bone marrow smear. It takes four people to complete the piercing. The ex...

AI Technical Summary

Problems solved by technology

The existing puncture bed is only an ordinary hospital bed, which does not fix the child, or fixes the child relatively firmly and has no toughness, resulting in a strong sense of restraint for the child, resistance to the child, great pain, and lack of humanistic care

The other type has toughness, but when the child twists hard, it will cause the body to shake a lot, affect the puncture, it is difficult to guarantee the success rate of puncture, it is easy to cause puncture injury, failure and dilution of bone marrow fluid, and it is impossible to achieve accurate bone marrow cytology or bone marrow biopsy
