A fully openable transport cabin for critically injured patients

Abstract

This invention provides a fully openable critical patient transport cabin, comprising an inner cabin unit and an outer cabin unit. Thermal insulation layers are provided between the inner upper cabin and the outer upper cabin, and between the inner lower cabin and the outer lower cabin. The elongation rate of the main body of the outer cabin unit is less than that of the main body of the inner cabin unit. When the end cap zipper and the outer sealing zipper are opened simultaneously, the rotation angle of the outer upper cabin relative to the outer lower cabin is greater than or equal to 270°. Alternatively, the outer sealing zipper extends to the end cap, so that when the outer sealing zipper is fully opened, the rotation angle of the outer upper cabin relative to the outer lower cabin is greater than or equal to 270°. The outer upper cabin of this invention can be fully opened, allowing the injured patient to lie flat on the air cushion at the bottom of the cabin. Medical personnel can perform resuscitation, intravenous infusion, and vital sign monitoring without obstruction. After the resuscitation work is completed, the cabin can be directly closed, pressurized, and transported.

Description

Technical Field

[0001] This invention belongs to the technical field of plateau rescue equipment, and in particular relates to a fully openable transfer cabin for the treatment of critically injured patients. Background Technology

[0002] Rescue and transport equipment used in high-altitude areas requires pressurization to restore the injured to a near-flatland state, thereby preventing further deterioration of pulmonary edema and cerebral edema. Existing pressurized medical transport equipment generally falls into two categories: land-based pressurized chambers and diving rescue chambers. Current medical rescue chambers or soft oxygen chambers for healthcare typically have an opening angle of less than 180°, with hatch lengths generally around 1.6 meters, making treatment and entry / exit for the injured extremely inconvenient. The inability to open and close the chamber significantly stems from limitations imposed by the material properties and structure of the chamber. As is well known, common pressurized chambers consist of two layers: an inner chamber base fabric and a sealing zipper base fabric formed by high-frequency welding or adhesive bonding. The sealing principle of the zipper is as follows: the zipper teeth lock onto the zipper base fabric; when the zipper closes, the metal zipper teeth are clamped, compressing the sealing strip below the metal head to achieve a seal. Therefore, if the sealing zipper is stretched or deformed, the metal teeth will deform, and the compressive force will loosen, causing the seal to fail. How to improve the opening of the transfer cabin while ensuring structural stability, so as to facilitate the entry and exit of the wounded, is a problem that urgently needs to be solved. Therefore, it is necessary to optimize and improve the existing cabin structure. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a fully openable transfer cabin for the treatment of critically injured patients.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0005] A fully openable critical patient transport cabin includes an inner cabin unit and an outer cabin unit. The inner cabin unit includes an inner upper cabin and an inner lower cabin, with the inner upper cabin and inner lower cabin hinged on one side and connected on the other side by an inner sealing zipper. The outer cabin unit includes an outer upper cabin and an outer lower cabin, with the outer upper cabin and outer lower cabin hinged on one side and connected on the other side by an outer sealing zipper. Thermal insulation layers are provided between the inner upper cabin and the outer upper cabin, and between the inner lower cabin and the outer lower cabin. The outer... Both the upper compartment and the outer lower compartment include a main body and end caps on both sides. The elongation rate of the main body of the outer compartment unit is less than that of the main body of the inner compartment unit. The two end caps on the same side are connected by an end cap zipper, so that when the end cap zipper and the outer sealing zipper are opened at the same time, the rotation angle of the outer upper compartment relative to the outer lower compartment is greater than or equal to 270°. Alternatively, the outer sealing zipper extends to the end cap position, so that when the outer sealing zipper is fully opened, the rotation angle of the outer upper compartment relative to the outer lower compartment is greater than or equal to 270°.

[0006] Furthermore, the outer upper compartment is provided with an inflation port and an vent port, with a one-way valve installed on the inflation port and a vent valve installed on the vent port.

[0007] Furthermore, the outer upper cabin and the inner upper cabin are provided with corresponding viewing window openings, and viewing windows are installed at the viewing window openings.

[0008] Furthermore, the inner cabin is made of knitted fiber material with a tensile strength of over 15%, while the outer cabin is made of multi-strand twisted fiber material with a tensile strength of less than 5%.

[0009] Furthermore, the outer upper compartment and the outer lower compartment are covered by an overlapping covering layer to cover the outer sealing zipper.

[0010] Furthermore, the thermal insulation layer is made of polymer foam material or aerogel material.

[0011] Furthermore, the inner sealing zipper is horizontally arranged corresponding to the center of the inner compartment unit axis, and the outer sealing zipper is horizontally arranged corresponding to the center of the outer compartment unit axis, with both located on the same side of the transfer compartment.

[0012] Furthermore, stretcher poles are provided on both sides of the outer upper cabin or both sides of the outer lower cabin.

[0013] Compared with existing technologies, the present invention has the following advantages:

[0014] This invention features a rationally designed structure. The outer upper compartment of the outer unit can be fully opened, facilitating the treatment and transfer of wounded personnel by medical staff. During treatment, the compartment can be fully deployed, allowing the wounded to lie flat on the air cushion at the bottom with their bodies completely exposed outside the compartment. Medical personnel can then provide unrestricted treatment. After treatment, the compartment can be sealed with a zipper, allowing the internal microenvironment to be regulated. Pressurization and heating can then be performed to restore the compartment to a near-flat state, further promoting recovery. The transport compartment can then be used to quickly transfer wounded personnel to a lower-altitude rear hospital. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] A fully openable critical care transport cabin, such as Figures 1 to 4 As shown, the system includes an inner cabin unit and an outer cabin unit. The inner cabin unit includes an inner upper cabin 1 and an inner lower cabin 2, which are hinged on one side and connected on the other side by an inner sealing zipper. The outer cabin unit includes an outer upper cabin 3 and an outer lower cabin 4, which are hinged on one side and connected on the other side by an outer sealing zipper. Thermal insulation layers 5 are provided between the inner upper cabin and the outer upper cabin, and between the inner lower cabin and the outer lower cabin. For example, the thermal insulation layers are made of polymer foam or aerogel material. In extreme natural environments, this shields the cabin from the influence of the external environment (temperature, humidity, noise), ensuring that a microenvironment conducive to conserving the wounded's energy can be established inside the cabin.

[0025] The inner cabin is made of a knitted fiber material with a high tensile deformation capacity, exceeding 15% in elongation. The outer cabin is made of a multi-strand twisted fiber material with high tensile strength and low deformation, with an elongation capacity below 5%. The upper and lower outer cabins are covered by an overlapping layer to seal the outer zipper. When the cabin is under stress, the outer cabin deforms very little, effectively restraining the inner cabin. The minor deformation of the inner cabin is entirely compensated by the deformation of the inner cabin wall material. The sealing zipper on the inner cabin deforms very little, ensuring its reliable operation. Furthermore, the cabin fabric is highly scratch- and tear-resistant, making it resistant to tearing during patient transport and loading. Even contact or scratches will not compromise the patient's safety.

[0026] Both the outer upper and outer lower compartments include a main body and end caps on both sides. The elongation rate of the main body of the outer compartment unit is less than that of the main body of the inner compartment unit. The two end caps on the same side are connected by an end cap zipper, so that when the end cap zipper and the outer sealing zipper are opened simultaneously, the rotation angle of the outer upper compartment relative to the outer lower compartment is greater than or equal to 270°. Alternatively, the outer sealing zipper extends to the end cap position, so that when the outer sealing zipper is fully opened, the rotation angle of the outer upper compartment relative to the outer lower compartment is greater than or equal to 270°.

[0027] The aforementioned outer upper cabin is equipped with an inflation port and an deflation port. A one-way valve 6 is installed on the inflation port, and a deflation valve 7 is installed on the deflation port. The aforementioned inner lower cabin has a basal air cushion 8 located on its inner side, and a strap assembly is installed on the side wall of the inner lower cabin. The strap assembly includes a head strap 9, a waist strap 10, a hand strap 11, and a foot strap 12. A heating unit is installed inside the basal air cushion, and an aviation socket 13 is located on the end cap of either the outer upper or outer lower cabin. This aviation socket is connected to the heating unit via a cable. Corresponding viewing window openings are provided on the outer upper and inner upper cabins, and viewing windows 14 are installed at these openings. The basal air cushion provides a bed-like surface for the injured, facilitating medical treatment; it also provides thermal insulation to prevent heat conduction and vibration damping, shielding the injured from the effects of uneven ground and preventing secondary injuries.

[0028] The aforementioned inner sealing zipper is horizontally arranged corresponding to the center of the inner compartment unit's axis, and the outer sealing zipper is horizontally arranged corresponding to the center of the outer compartment unit's axis, with both located on the same side of the transfer compartment. Additionally, stretcher poles 17 are provided on both sides of the aforementioned upper outer compartment or both sides of the lower outer compartment to facilitate the transport of the wounded. The end caps of the upper and lower outer compartments are bound together by crisscrossing outer straps 15, and the main body of the upper and lower outer compartments are connected by several parallel outer fastening straps 16. This ensures the compartment's load-bearing capacity, resulting in better stress resistance and airtightness under pressure, stronger pressure deformation resistance, and reduced susceptibility to damage, leakage, and compartment failure.

[0029] This invention features a rationally designed structure. The outer upper compartment of the outer unit can be fully opened, facilitating the treatment and transfer of injured personnel by medical staff. Injured personnel can lie flat on the air cushion at the bottom of the compartment, allowing medical personnel to perform resuscitation, intravenous infusion, and vital sign monitoring without obstruction. After the resuscitation work is completed, the compartment can be directly closed, pressurized, and transferred. Furthermore, the zipper deformation of the transfer compartment provided by this invention is minimal during pressurization, typically controlled to around 2%. Additionally, the zipper arrangement at the end caps during outer compartment wrapping and compartment opening further enhances structural pressure resistance and overall stability.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
