Description

Technical Field

[0001] The invention relates to the field of trays for operating room nursing, in particular to a cross-infection-proof detachable tray for temporarily placing instruments for operating room nursing. Background Art

[0002] During the operation in the operating room, doctors use a large number of surgical instruments, such as suture needles, scalpels, hemostatic forceps, etc. Because doctors need to use these surgical instruments at any time, they will place the surgical instruments on temporary storage equipment. These instruments and tools are generally placed in surgical nursing trays by nurses and handed to the doctors when they need them. However, the current surgical nursing tray design is relatively simple, the desktop space is limited, the number of trays and tools that can be placed is small, and the height cannot be adjusted, which causes inconvenience to the operation of nurses and has low practicality. Among them, an operating room with application number "CN202120282459.0" A new type of tray for nursing in the operating room can place more surgical instruments on a table with limited space through an expansion device, and can reduce the occupied space while ensuring that there are enough surgical trays. The height of the tray can be adjusted according to the height of the surgical operation through an adjustment device, making it convenient for nursing staff to take and place the instruments. However, this tray still has certain shortcomings during use: since it is equipped with multiple trays for placing instruments, a high degree of concentration is required during the process of taking and placing instruments on different trays. In some emergency situations or if you are not careful, the instruments may be placed in the wrong tray, resulting in cross infection, and the tray cannot be disassembled and replaced, making it inconvenient to use.

[0018] Compared with the prior art, the present application has the following advantages:

[0019] (1) The installation cavity is provided in the placing table, the rotating disc is rotatably installed in the installation cavity, the plurality of swing arms are hingedly installed on the surface of the rotating disc, the bracket is hingedly installed at one end of the swing arm, the L-shaped fixed clamping block is fixedly installed at the top of the bracket, the L-shaped fixed clamping block is slidably installed in the guide groove obliquely provided on the surface of the placing table, the slide rail is installed on the inner wall of the installation cavity corresponding to the guide groove, the bracket is slidably installed on the surface of the slide rail through the guide block, when the rotating disc rotates, the swing arm on the surface is displaced, the swing arm moves to drive the L-shaped fixed clamping block to slide in the guide groove and approach, so as to fix the placing tray in the placing table through the L-shaped fixed clamping block, the L-shaped fixed clamping block can be temporarily fixed on the placing tray of different sizes by adjusting the sliding position of the L-shaped fixed clamping block, when disassembly is needed, the rotating disc is reversely rotated to drive the L-shaped fixed clamping block to move away from the four edges of the placing tray, so as to facilitate the disassembly of the tray, the nursing personnel can replace the placing tray according to the operation requirement during the operation process, so as to avoid the misplacement caused by the simultaneous use of multiple placing trays and the cross infection, the length of the slide rail is greater than the length of the slot of the guide groove, so as to satisfy the sliding range of the guide block driving the bracket along the slide rail;

[0020] (2) Through the provided lifting assembly, a lifting cylinder is inserted into the interior of the support sleeve, and the screw rod installed in rotation inside the support sleeve is inserted into the interior of the lifting cylinder. A slider is installed on the surface of the screw rod, and the lifting cylinder is connected to the slider. When the rocker wheel outside the installation cylinder is rotated, the worm is driven to rotate. The worm is meshed with the worm gear, so that when the worm rotates, the screw rod is driven to rotate by the worm gear, and the screw rod rotates to rotate. Since the limit blocks are installed on both sides of the slider, the limit blocks slide in the limit grooves opened on both sides of the inner wall of the support sleeve, so that when the screw rod rotates, the slider slides up and down along the fiber groove, thereby driving the lifting cylinder on the top to follow the lifting adjustment through the slider. Before the operation, the lifting cylinder is adjusted to a height suitable for surgical nursing staff to pick up, thereby improving the flexibility of the placement table;

[0021] (3) The storage box is installed on the surface of the I-shaped base. A multi-layer placement rack is installed inside the storage box. The spare placement tray is placed in the placement rack to facilitate the replacement of the placement tray according to needs. A reel is installed on the top of the storage box. Bearings are installed at both ends of the reel. The rotating shaft is rotated and installed in the reel through the bearings. A dust curtain is wrapped around the surface of the rotating shaft. The dust curtain plays the role of shielding the storage box to prevent the spare placement tray from being contaminated during surgery. Coil springs are installed at both ends of the rotating shaft. When the hanging rod at the bottom of the dust curtain is pulled, the dust curtain drives the rotating shaft to rotate, thereby compressing the coil spring and storing force. After the hanging rod is pulled down, it is fixed by a hook. When the dust curtain needs to be opened, the hanging rod is removed from the hook. The coil spring releases the stored force and drives the rotating shaft to rotate, thereby rolling up the dust curtain on the surface of the rotating shaft. BRIEF DESCRIPTION OF THE DRAWINGS
