Operating anesthesia head rack

Abstract

The invention relates to an operating anesthesia head rack. A supporting fan-shaped surface comprises a rotating shaft which is arranged in the middle of a transverse rod, wherein a plurality of fan blades are arranged on the rotating shaft; a universal mechanism is additionally arranged on the transverse rod; the universal mechanism is connected to a fixed pillar by virtue of a supporting rod; a telescopic rod comprises a first hollow rod and a second hollow rod; at least one part of the second hollow rod is located within an inner hole of the first hollow rod; one end of the first hollow rod and one end of the second hollow rod are connected by virtue of an eccentric lock mechanism; the eccentric lock mechanism comprises an eccentric lock cylinder and a non-closed-loop lock sleeve; one end of the eccentric lock cylinder is integrally fastened with the second hollow rod; a cam is arranged on the peripheral surface of the other end of the eccentric lock cylinder; and the lock sleeve is tensioned between the cam and the inner wall surface of the first hollow rod when the second hollow rod is rotated after the lock sleeve is arranged on the cam of the eccentric lock cylinder. The head rack provided by the invention is prevented from sliding after being lifted; therefore, the head rack has the advantage of being high in stability.

Description

technical field [0001] The invention relates to an anesthesia head frame for operation. Background technique [0002] In the process of preparing for anesthesia, many anesthetics and instruments are needed, and the operation rhythm is often very tight, and every second counts. In order to facilitate the operation, sometimes the doctor will spread a sterile towel on the patient, and place the medicine used for anesthesia induction on the tray and Relevant equipment during general anesthesia (such as: tracheal intubation, etc.) is placed on the sterile towel. On the one hand, this operation does not conform to the norms (contrary to the concept of love and injury and the principle of medical aseptic operation), and on the other hand, the tray is not easy to place stably . [0003] For some patients with endotracheal intubation, the ventilator needs to be supplied immediately through the threaded hose, and the ventilator is generally set next to the operating bed in front of t...

Problems solved by technology

The above-mentioned positioning method through the knob will cause unreliable positioning of the inner tube. The reason is that although the contact between the knob and the outer circumferential surface of the inner tube is surface contact, the contact area between the two is small. It is unreliable, and when medicines, instruments and other items are placed on the fan, these items exert axial pressure on the inner tube, which is more likely to cause the inner tube to slide downwards. In this way, the final result is that the medicines, instruments and other items fall to the patient's head or body, causing harm to the patient, therefore, it is necessary to consider improving the telescopic rod of this anesthesia head frame
