It is not easy to do animal experiments and disaster relief, and it is easy to carry and easy to carry. Conclusion: The device belt has the functions of putting medical instruments, power supplies and gas types together, and is easy to move and carry. Compared with equipment hanging towers and wall-mounted equipment belts, the production cost is low, and there are clinical, scientific research and disaster medicine. Larger application value is worth promoting.
1 Introduction
The head mast for medical use and the bedhead unit are special devices that can be used to put together the instruments, power supplies, and gas types used. In clinical medical work, many modern new medical instruments and equipment, such as monitors, ventilators, infusion pumps, syringe pumps, oxygen, anesthetic gases, negative pressure, compressed air and other gas pipelines, power supply lines and various power outlets Etc., it is easy to cause crowded space around the operating room and hospital bed, hinder medical operation, and even delay the best treatment opportunity. Equipment hanging towers and equipment belts are a new collection device for modern medical instruments and equipment. All instruments, equipment, power supplies, gas lines, etc. can be placed in a centralized organization to ensure that there is enough rescue space around the operating room and the ward to ensure emergency. Normal use of equipment and power supply circuits. Equipment hanging towers and equipment belts are usually used in clinical intensive care units, operating rooms, emergency rooms, general wards and other clinical departments in tertiary hospitals.
China is a disaster-prone country. China's disaster medical rescue system and technology have made great progress in recent years. It has played a vital role in disaster relief such as the Hanchuan earthquake, but it also revealed many shortcomings in the rescue implementation process. It is worth discussing and improving m. The performance of most of the rescue machinery is huge, and the portable excavation and rescue equipment is lacking. Therefore, the development and use of small portable multi-functional rescue equipment is very necessary, which will bring innovation and progress to disaster medicine.
The portable medical equipment belt made in our hospital is shown in Figure 1. With wall and tower equipment, it provides oxygen, air, vacuum suction and power, as well as mobile and portable. According to the clinical and first-aid procedures and functions, provide first-aid, surgery, shadowless lamps, anesthesia machines, anesthesia monitors, high-frequency electric knives, inspection, X-ray and other systems of power supply, equipped with central oxygen supply, central vacuum suction, etc. Fully equipped. It works well in the operation of our hospital ward and animal laboratory.
2 Portable medical equipment with overall structure and parameters
With reference to the HTM2022 standard, the design concept of electrical separation and strong and weak electrical separation is adopted. The portable equipment consists of four parts: the lateral gas pipeline operation panel, the longitudinal power supply pipeline operation panel, the base and the wheel, as shown in Fig. 1(a), b) shown. It adopts aluminum alloy one-time forming technology. The thickness of aluminum alloy sheet is 2 mm, which has the advantages of “light, hard and toughâ€.
As shown in Figure 1 (a), (c), there is a roller under the base, and the rear wall of the base is provided with a power connection terminal, an oxygen pipe connection pipe, a negative pressure pipe connection pipe, and an air connection pipe, as shown in Fig. 1 (b). ) shown. A support shell is arranged on the base, and a power switch and a power socket, a data line interface, a grounding terminal, an oxygen pressure gauge, a negative pressure gauge and an air pressure gauge are fixed on the shell wall of the support shell.
As shown in Fig. 1(b), the supporting shell is connected with an oxygen gas guiding tube, a negative pressure air guiding tube and an air air guiding tube; the oxygen air guiding tube, the negative pressure air guiding tube and the air air guiding tube respectively correspond to respective oxygen pressure gauges and negative The pressure gauge and the air pressure gauge are connected.
As shown in FIG. 1(a), the support housing is provided with a device belt housing, and the wall of the device belt housing is provided with a medical gas socket, and the medical gas socket is respectively an oxygen gas socket, a negative pressure gas socket, and an air gas socket. As shown in Figure I(b), the oxygen gas socket is in communication with the oxygen gas guiding tube; the negative pressure gas socket is in communication with the negative pressure air guiding tube; and the air gas socket is in communication with the air guiding air tube.

Figure 1 Schematic diagram of equipment belt structure
In the specific design, there are four cavities in the support housing, which are used to install gas pipelines, strong electric pipelines and weak electric pipelines.
(1) Gas pipeline operation panel design: the operation panel size is 53 cmx13 cmx6 cm, and the gas pipeline is installed separately, including 2 air pipelines, 2 oxygen pipelines, and 2 vacuum suction pipelines for one unit. Bed use.
(2) Power line operation panel design: The vertical power supply line operation panel is compactly cmx68 cmx7.5 cm. It is equipped with three monitoring pressure gauges and three power sockets to provide power for medical equipment.
(3) Base: Made of stainless steel, the volume is 35 cmx35 cmx15 cm, filled with cement, keeping the bottom enough weight to avoid tilting. All gas and power lines are routed from the base. The line is concentrated to the outside, and all gas bottles or other equipment can be placed outdoors without taking up indoor space.
(4) Wheels: There are 4 universal wheels at the bottom to facilitate the movement of equipment in different rooms or different places in the room.
(5) The equipment has a large internal cavity and can be loaded with a variety of electrical equipment and gas outlets, including lighting, reading lights, special purpose lights, power outlets, telephone or network outlets, electrical switches, medical gas outlets, nurse calls System, etc.
(6) It adopts modular structure assembly, that is, the main panel is composed of one independent standardized module, which has beautiful style and strong expandability. The panel is assembled by crimping and is easy to disassemble for easy maintenance and cleaning.
