Description

Technical Field

[0001] The utility model relates to the technical field of medical transfer cabins, in particular to a pressure-adjustable sealed medical transfer cabin. Background Art

[0002] At disaster sites such as fires, chemicals / toxic fumes, etc., the treatment of the wounded must be fast and timely. During the transfer process, environmental factors such as toxic fumes and high temperature burns can damage the respiratory tract, which is the key to the success rate of patient treatment. In a disaster environment, rescuers can protect themselves by wearing fireproof isolation suits and gas masks, but for the wounded at the disaster site, there are often the following hidden dangers: 1. It is time-consuming and laborious to put a gas mask on unconscious wounded; 2. The gas mask may further aggravate the respiratory hypoxia of the wounded; 3. In the process of wearing a gas mask, secondary damage is caused to possible cervical spine injuries; 4. There is no effective protection for the trunk and limbs of the wounded. There are currently no high-temperature resistant transfer cabins available.

[0003] The negative pressure sealed transfer cabins currently used in the market have disadvantages such as large size and weight, inability to adjust pressure, not resistant to high temperatures, and high price.

[0004] Chinese patent CN2776361Y discloses an inflatable sealed oxygen chamber stretcher, which is provided with an inflatable sealed oxygen chamber connected to the stretcher handle and crossbar. The upper part of the oxygen chamber is arched and the lower part is a rectangular parallelepiped. A double-layer sealed patient entrance with an observation window is provided on the chamber body, and an overpressure exhaust valve is provided on one side of the arched surface; a compressed oxygen cylinder and a CO2 purifier powered by the oxygen cylinder are provided at one end of the bottom surface. The compressed oxygen cylinder is also connected to an automatic lung oxygen mask at the other end of the bottom surface through the CO2 purifier and a high-pressure oxygen supply pipe. A mask switch is also provided at the connection between the mask and the oxygen supply pipe; a chamber body inflation hand ball and an inflation valve are provided at the lower part of one end of the chamber body. The sealed oxygen chamber can only be pressurized in one direction and has no pressure regulating function; it can only filter carbon dioxide, but cannot filter toxic and harmful gases; its applicability to high temperature environments is also unclear, and its applicable occasions are relatively single. In addition, the sealed oxygen chamber is large in size, cannot be stored, and is not convenient for storage and transportation.

[0005] Therefore, in view of the practical problem that different rescue requirements require different cabin pressures, it is urgent to develop a sealable transfer cabin that can adapt to different rescue requirements and can be used to transport the wounded and sick, so as to effectively improve the efficiency of rescue and transfer in emergency situations.

The inflatable frame 11 is also provided with a nylon buckle 112 that can be connected to the stretcher buckle. The cabin sealing surface 12 is provided with a warning color coating. Both sides of the cabin sealing surface 12 along the length direction are provided with observation windows 14, which can observe the conditions of the injured and sick in the cabin. The top surface is provided with a waterproof sealing zipper 15 for transporting the injured. The cabin sealing surface 12 in this embodiment includes a TPU film layer and a polyester cloth layer, specifically a sealing material synthesized by hot pressing a thermoplastic polyurethane elastomer rubber film and a polyester cloth.

[0040] like Figure 2 As shown, a plurality of interfaces 13 are provided on the cabin sealing surface 12, and the interfaces 13 are respectively provided at both ends near the bottom of both sides of the cabin sealing surface 12, and a one-way vent 131 is provided on the interface 13. Each interface 13 is connected to a filter component 2, and the filter component 2 includes a microbial filter component and a smoke filter component, and a suitable filter component can be replaced according to the specific scenario. In this embodiment, all or part of the filter component 2 can be connected to the pressure regulating component 3 according to the specific scenario. The pressure regulating component 3 is provided with an air inlet 31 for inflating the inflatable sealed cabin 1 and an air outlet 32 ​​for extracting air from the inflatable sealed cabin 1. In this embodiment, the pressure regulating component 3 and the filter component 2, as well as the filter component 2 and the interface 13 are connected through a sealed connecting pipe 4.

[0041] Embodiment 3:

[0042] like Figure 1-2 As shown, a pressure-adjustable sealed medical transfer cabin of this embodiment includes an inflatable frame 11, an inflatable connection port 111, a nylon buckle 112, a cabin sealing surface 12, an interface 13, a one-way vent 131, an observation window 14, a waterproof sealing zipper 15, a pressure regulating component 3 and a filter component 2.

[0043] The inflatable sealed cabin 1 is supported by a rectangular inflatable frame 11, and a portable 55g carbon dioxide cylinder is used as the inflatable gas source. The inflatable sealed cabin 1 can be fully opened within 10 seconds through the inflatable connection port 111, and the wounded enter the cabin through the waterproof sealing zipper 15. The cabin sealing surface 12 is made of a new type of sealing material synthesized by hot pressing of thermoplastic polyurethane elastomer rubber (TPU) film and polyester cloth, with an outer dimension of 190×60×60cm and an inner space volume of 684000cm 3The appearance is bright yellow warning color, and observation windows 14 are provided on both sides of the cabin body to observe the condition of the injured and sick in the cabin. There are three interfaces 13 on both sides of the transfer cabin of this embodiment, two of which are located at the head end of the cabin body and one at the tail end of the cabin body. The interface 13 has a convertible spring gasket built in as a one-way vent 131.
